    • RE: Halo - is the battery capacity a lie?

      @SurixTM what I'd expect from them is pretty straightforward: admit the mistake, and update the specs on Amazon, etc.

      Falsifying battery capacity can be a major reason for a (temporary) product ban. Regulations exist for a reason, namely so that companies can't just write whatever they want on the packaging. You can't sell a power bank that is 5000mAh as if it was 20000mAh (no matter how you twist the math). Thereby you also can't sell a projector that has an at best 9000mAh battery pack (at 3.6/4.2V as per it is customary to indicate) as a 17000mAh one.

      I bought my Halo partly because it has a built-in battery. I expect the capacity to be as indicated on the packaging, not some random measurements that were done in a lab for "play time".

      @Ari there's no confusion, I ran the numbers down already.

      Your packaging, as well as the battery's packaging, claims 59.454Wh.

      • This is 17.000mAh at exactly 3.476V - which is not a standard voltage to measure capacity at, for batteries or power banks
      • At 3.6V (nominal voltage of Li-ion batteries) we get 16.500mAh, which is kinda close, but not close enough to be considered a marginal error.
      • At 4.2V, it's even less, 14155mAh

      Then, the problem of battery cells. Again, the photos of the Halo interior clearly show it is a 3-cell pack, further confirmed by the voltage (~11Vnom), which is precisely 3x 3.6V (which is 10.8V, but we can take 11 if the cells in question have a slightly higher optimal maximum voltage).

      So we are ought to believe that the combined capacity of the 3 cells is 17100mAh, which would put each cell at 5700mAh capacity - that is still over 50% higher than any actually verified 18650 cell on the market. Simply said, a 3.6V 5700mAh battery, in the shape shown on the interior photos, cannot exist.


      And as I mentioned on Facebook, I did some measurements on the power usage of the Halo.


      Brightness: Max
      Image mode: Game
      Power usage is ~52W with display on, ~14W display off
      Brightness: Max
      Image mode: Bright
      Power usage is ~50W with display on, ~13W display off


      Brightness: Power save
      Image mode: Game
      Power usage is ~18W with display on, ~14W display off
      Brightness: Power save
      Image mode: Bright
      Power usage is ~16W with display on, ~12W display off


      Brightness: Night
      Image mode: Game
      Power usage is ~40W with display on, ~14 display off
      Brightness: Night
      Image mode: Bright
      Power usage is ~38W with display on, ~12W display off


      Brightness: Office
      Image mode: Game
      Power usage is ~70W with display on, ~13W display off
      Brightness: Office
      Image mode: Bright
      Power usage is ~70W with display on, ~13W display off


      Brightness: Video
      Image mode: Game
      Power usage is ~57W with display on, 13W display off
      Brightness: Video
      Image mode: Bright
      Power usage is ~55W with display on, ~13W display off


      Brightness mode "Max" is my custom setup that sets every colour channel to 100% as well as the actual brightness.

      Brightness mode "Night" is also a custom setup with 50% brightness, and colours tuned to be more realistic (R: 40% G: 40%, B: 50%)
      I've taken multiple measurements in each mode, to make sure everything is correct and I didn't run into some sneaky drip charging of sorts.

      I also tried video playback with max and half volume - the difference was almost negligible, 2-3W at most on max volume with local hardware decoding h.264 1080p stream from a local server.

      Conclusion:

      • The board (with Android TV running, connected to WiF and the Bluetooth remote), depending on mode, eats around 12-15W
      • The projector assembly, depending on brightness, can eat up to 55W on its own (in Office mode). How Office mode can be more power hungry than my custom Max mode, I don't understand - maybe Ari has an explanation?
        In power save mode, the projector assembly eats between 15-25W
      • When running from battery power, like most devices, the Halo most likely goes into a more power-saving mode (not display, but hardware!), such as lowering the fan speed, reducing the CPU frequency and not bumping it up to maximum unless needed, which would result in the board power usage going down to around 5-7W.
      • When running from battery power, the projector brightness is reduced, but not as much as the "Power save" mode. I'm guessing a ~20-30% reduction in brightness, which should lower power usage by as much as 50%, thereby giving an approx. power usage of 7W + 20W ~ 30W
      • Speaker volume (weirdly) does not affect power usage

      This equals the rough estimate of 2 hours playback on battery power, as the battery would be almost 60Wh.

      Generally, I think the current OS is badly optimised, and the projector assembly handling as well. The Anker Nebula Mars 2 Pro, for example, has a 48.642Wh battery (4 cell 18650 at 3350mAh capacity), and slightly worse brightness (500 ANSI lumen on battery vs. the 600 ANSI lumen of the Halo), and although it uses a different CPU (based on the specs, a Qualcomm Snapdragon 205), the board's power usage is negligible. So how can the Anker manage 3 hours out of that <50Wh battery, when our 60Wh one can barely push out 2 hours?

    • RE: Halo - is the battery capacity a lie?

      @Ari it's been over 5 days. I'd like to see some results about the battery. It shouldn't be so hard to open up a production unit in your office, and open up the battery packaging to see the actual cells.

    • RE: Halo - is the battery capacity a lie?

      @SurixTM that's why I asked @Ari to have one of the Halo battery packs in their manufacturing line opened. The cells would need to be imprinted with either the actual specs, or the chemistry and capacity indicators at least.

      @Ari the FCC images clearly show that the Halo has a 3-cell battery, not 4-6. And as someone who has worked for companies designing hardware that had to pass FCC certification... They will ask you to re-certify if you do as little as change the casing colour. A battery pack change would assuredly require a re-certification. Seeing how you haven't submitted anything that is public since July, and before that, it's the first and only Halo application.

    • RE: Halo - is the battery capacity a lie?

      @SurixTM feel free to use it! I'm also Hungarian by the way 😉

      I've messaged the manufacturer of the battery, since they're the ones who print the labels. It is quite possible that someone at the battery manufacturer fucked up big time, the product got mislabeled with the bad data, and Xgimi just thought that a cheaper, smaller, but much larger capacity battery would fit the Halo more... I just find it incredibly perplexing that not just one, but TWO companies' electronic and battery engineers have skipped over this obvious thing. I'm not even an electronic engineer by degree, and the moment I saw the 3-cell battery pack, it was straight obvious that it can't be almost 60Wh - unless it's some new battery technology, but that would be advertised to hell on the packaging. I just hope we get an explanation soon.

    • RE: Halo - is the battery capacity a lie?

      @Ari There IS a PMIC in the Halo - a Power Management Integrated Circuit. It handles charging the battery. And to know how to charge said battery, it needs to be able to calculate the battery percentages. But the issue is not with the battery percentage... It's with the actual capacity of what is on paper (or rather, on your website), i.e. what you promised, versus what's actually in the Halo.

      What if I told you the power bank I'm selling you is 60Wh, and when you get home, you realise that it is only 20Wh? What if I sold you a house that is supposed to be 60 square meters, but then you get to it, and realise it's only 20 square meters? See my problem? My problem is that throughout the process of purchase, each and every person who was promised this "magical" 17100mAh battery, they were

      LIED TO.

      Specifically,

      YOU LIED.

      I'm stating that YOU, @Ari lied, because you're here representing your company, and you literally took zero effort to actually read my post and understand what the issue is. I paid £760 for this device, and what am I receiving for that money? A device I could've put together from approx. £300-400 (depending on if I can source the DLP projection assembly from the UK, or have to order it from Texas Instruments from the US or China), and apparently zero support, sprinkled with lies.

      @salmanmunawar please stop derailing this thread. The battery capacity issue is much more important than the HDR issue - latter can be fixed with a firmware upgrade, but I doubt Xgimi will be replacing the units they already sold with units that have the actual advertised battery capacity. HDR has had its own threads, please continue the discussion there.

    • Halo - is the battery capacity a lie?

      I've been doing some research into the battery of the Halo, since the claimed 17100mAh capacity simply doesn't seem to add up.

      First, here's the claim from the website:

      3719f240-96c0-409f-a460-52b65a2bcc07-image.png

      I'd like to point out the obvious mathematical error. The website claims 58.6Wh at 17100mAh/4.2V. First of all, the formula to calculate battery capacity is Voltage multiplied with Current (or Amperage in other words). To simplify this, the formula is, using the unit indicators is:

      Wh = Ah * V
      

      What the website claims is the following - having converted the 17100mAh to 17.1Ah (1000mAh = 1Ah):

      58.6Wh = 17.1Ah * 4.2V
      

      Except first grade math already disproves this: 17.1 * 4.2 is 71.82, NOT 58.6! That's already a ~20% difference. 58.6Wh at 4.2V would be 13.95Ah, or 13950mAh. And 58.6Wh at 17.1Ah would mean 3.42V. No pairing adds up.

      Not to mention that battery capacity is generally calculated not at the maximum voltage of the cells, but at the nominal voltage - this is due to "voltage sag" - as the battery discharges, its internal voltage drops from the maximum (4.2V) to approx. halfway empty (3.6V) to completely discharged (3-3.2V depending on the cell). During this time, the current that can be drawn from the battery raises, to provide an even wattage (say, to get 5W out of a battery at 4.2V will require an approx. 1.19A current, but at 3.6V it needs more, 1.4A, and at the end of the battery, up to 1.6A). The more amps you pull, the faster the battery discharges, so altogether you are closer to the actual capacity of the battery if you calculate with the nominal voltage, 3.6V on average.

      At 3.6V, the numbers look a bit better: 17.1Ah * 3.6V = 61.56Wh which is much closer to the claimed capacity. Still not quite right though. The closest match is still 3.42V, but that voltage is completely unconventional, even for LiFePo4 cells. Conclusion: either the indicated power capacity (58.6Wh) or the indicated current capacity (17100mAh) is wrong.

      Conclusion 1: The indicated capacity on the website is WRONG

      Now, I couldn't rest, so looked some details up. Luckily, the FCC - the Federal Communications Commission (yes, those assholes who almost ruined net neutrality for some sweet lobby money) does one thing that we all benefit from. They certify any and all devices that are to be sold on the US market, and can be used for communication in any way. If it includes any sort of wired or wireless communication - WiFi, Bluetooth, USB, hell, if it outputs Morse chirps, even that is covered - they need to certify it. One key part of this process is to take measurements and photos of the device in question, outside and in. Lucky for us, Xgimi did not ask for confidentiality, so the interior and exterior photos are available, albeit at a reduced resolution. I would like to point out a close up photo of the battery:

      output-onlinepngtools.png

      According to the packaging, this battery is 11.01V nominal, 12.6V maximum voltage, at 5400mAh - giving us an ample 59.454Wh, a whole Watt hour more than the website claims! Well, we obviously have to consider conversion loss - the cell is around 11V, but most integrated circuits like the CPU in these devices, work at 3.3V - this was specifically chosen for Li-Ion cells, because most are tolerant of a little over-voltage (which can be easily regulated with a step down buck converter, and are quite efficient), so you could technically run most boards off of a Li-Ion cell directly. But our cell is 11V!

      The reason for this is also simple - the CPU, the board, etc. requires a specific level of wattage. At 3.6Vnom, you need more amps to provide the same wattage. A math example: 50W at 3.6V needs ~14A, whereas at 11V, you need less than 5A. This is important because Li-Ion batteries are designed to provide a given continuous (and another rated, called "spike") current. If you vape, you might've come across of people warning you not to use a low continuous current cell in your high wattage vape. E.g. a 160W vape is usually using two Li-Ion batteries connected in series (connecting batteries in series increases voltage, connecting them parallel increases current rating), because they need to provide up to 4.5-5V voltage - and a step down buck converter is much more efficient converting from 7.2V (the nominal voltage of two 3.6V cells connected in series) at a low current, than a step up unit converting a high current 3.6V input to 5V. So, at 7.2V, you will need cells that can sustain ~22A continuous current draws. Generally it's recommended to go for 25-30A cells.

      So, as the above image shows, we have 3 cells, obviously connected in series - since the voltage is exactly 3 times as much as the nominal, and maximum voltage of a single Li-Ion cell is. 11.01V / 3 = 3.67V and 12.6V / 3 = 4.2V.

      Conclusion 2: The battery in the Halo is a 3S cell

      Now, here comes the weird part. I did a bit of photo measuring, using the less clear photo of the internals, that clearly shows a millimeter ruler:

      ea2a4c21-ebb0-41fd-8323-39cb762edea8-image.png

      I know, I know, really bad resolution. But enough to work with! Here is the result:

      Screenshot 2020-09-03 at 03.44.04_measure00.png

      The total cell height is 69.5mm (number 3 on the image), but we can clearly see from the first, higher resolution photo that the battery pack has a "hat" (on the bottom, where the wires are coming out). This "cap" is roughly 4mm in height (number 4 on the image), making the batteries within the wrapper (which you can clearly see, are 3 cylindrical units) about 65mm high.

      The width of the pack is roughly 56.5mm - divided by 3, it's roughly 18.8mm. Take away the wrapper, and we have three, approx 18.5mm thick cells.

      These values are eerily close to the 18650 battery format - used in all sorts of electronics, from flashlights, to laptop batteries: yes, when your laptop manufacturer says it's a "6 cell battery", it means there's 6 of these bad boys in it. Or, an even bigger surprise - those Tesla electric cars? They pack some 7000+ of these cells to drive you around (note: Tesla recently changed from 18650 to 21700 - a battery cylinder that is 21mm wide and 70mm long, due to better energy density). But 21700 is way too big for this pack to work out.

      Conclusion 3: The battery pack is built of 3x 18650 cells

      Well, the Halo only got three of these.

      An interesting claim: 5400mAh?

      It is clearly visible that the claimed current capacity of these units is 5400mAh. There's only a little problem with that: if the batteries are connected in series, that means each and every cell is 5400mAh. Remember, battery voltage adds up in serial connection, current adds up in parallel connection. An 59Wh cell in parallels will be ~16000mAh at 3.6V, and the same 59Wh cell will be 5400mAh at 11V.

      Except... There's not a single (actually verified) 18650 cell that is 5400mAh! Sure, you can find AliBaba and Wish links that claim some ridiculously high capacity - often up to 9900mAh - but these are mostly lies. In fact those are mostly reject cells that could not deliver the needed continuous current draw, and were dumped, bought up by other companies who relabeled them, and are now selling basically explosives worse than the Galaxy Note 7 was. Most of the "my vape exploded" stories end up being these shitty, relabeled cells being sold to people who don't know better, and try to pull 20A on a battery that didn't even pass the 5A test. This causes a thermal runaway, and boom, battery bomb.

      The claimed 5400mAh capacity is actually 50% more than any verified cell in existence. Simply said, the claims on the battery are NOT CORRECT. In fact, if you divide it by 3, you get 1800mAh - which is a quite common capacity for everyday cells, with a usual continuous current rating of 10-15A. Since the Halo needs ~90W power (the charger is a 19V 4.7A one, which is in total ~89W), at 11V, the 10A provides ample power, allowing the Halo to draw roughly 110W at any time (turning on the device does cause a current jump which then settles, so I'm guessing the cells are rated 15A to provide headspace without damaging the batteries).

      The thing is... The math does not add up in any way if we go by the official documents. If my above statement is correct, and the manufacturer of these cells did indeed multiply not just the voltage, but the amperage of the cells by 3 as well, simply said, Xgimi's claims on the 17100mAh at 4.2V are a lie. In fact, this little "skimming" on the details triples the claimed capacity. I'm about 99% sure that these cells are indeed 1800mAh, putting the battery pack at 19.818Wh, or precisely at 1/3 of the claimed capacity. Quick math: 19.818Wh at 4.2V is 4700mAh, 27.5% of the claimed capacity. Even at 3.6V, it only adds up to 5500mAh, or 32% of the claimed capacity.

      FINAL CONCLUSION: WE'VE BEEN ACTUALLY CHEATED OUT OF 2/3 OF THE CLAIMED CAPACITY

      Another calculation I can run by you to verify this is the energy density of Li-Ion batteries, which is in the range of 250-693 Wh/L - this is coming from Wikipedia. We will do the math with both the highest and lowest density.

      First, let's calculate the volume of the pack! We know that it is roughly 70mm tall, 56.5mm wide, and the height comes easy, 1/3 of the width, or 18.83mm. For the simplicity I will calculate both the boxed volume (ignoring that the three cylinders do not fill all the available space), and the volume of 3x 18650 cells as well.

      The first, boxed volume is easy. 70 * 56.5 * 18.83 = 74 473 cubic millimeter, rounded up. 1 liter is exactly 1 000 000 cubic millimeter. So, we're talking about 7.5% of a liter, if we count by boxed volume. 7.5% of 250Wh is 18.75Wh, 7.5% of 693Wh is 52Wh. So even the highest density battery, filling out the whole space the battery pack occupies, would not be enough to get to the claimed 58/59Wh!

      Now, let's account for the packaging, the "hat" of wiring, and all. Let's count with 3x 18650 cells. The volume of a cylinder is V=Ï€ r^2 h

      The radius, r, is half of the diameter, which we established at 18mm - so it is 9mm. Height, h is 65mm. π is a constant, 3.14.

      So volume here would be: V = 3.14 * 9*9 * 65. The total volume of a 18650 cell is then ~16550 cubic millimeter. Triple it up, and you get 49600 cubic millimeter. Turns out, almost 1/3 of the volume of the pack is lost due to packaging, the batteries being cylinder shaped, and the wiring. But let's not get stuck on the details. Rounded up, because we're nice, this gives us 5% of a liter's worth of batteries. 5% of 250Wh is 12.5Wh, 5% of 693Wh is 34.65Wh.

      If we're kind, and average it out, we get:

      • 35.5Wh average for boxed volume
      • 23.6Wh average for proper battery volume

      Our previously calculated ~20Wh capacity is just around the average of proper battery volume - slightly less, since we calculated with low capacity (1800mAh) cells).

      @Ari I understand you're just community support and most likely have little to no oversight on the technical details, however I'd like to ask you to go into your R&D or manufacturing department, and just to verify, open up one of these battery packages. Seeing the specifications that are most likely printed on the cells, just under the blue plastic shrink wrap, would resolve this mystery once and for all. I won't call Xgimi liars outright - most likely you're purchasing these cells readily wrapped and labeled from another manufacturer, and have been misled yourself, however the battery being less than 1/3 of the advertised capacity is a serious issue, and would explain why the projector only lasts about 2 hours on battery power alone.

      I would also like to make note of the fact that the Mogo/Mogo Pro (and apparently there's a new model called Mogo Play coming out?) all have 4-cell batteries, and both of them come with considerably lower capacity - 36Wh and 44.8Wh, respectively. Wasn't it a bit suspicious for you that a smaller battery pack contains almost twice as much capacity? Didn't your engineers realise that all the power usage of the internals of the Halo is almost exactly 1/3 of the power usage needed to deplete the claimed battery capacity in that amount of time? If the labeling was correct, the Halo should be getting a much higher, approx. 6 hour battery life. I hope these questions can be answered properly, and not just wish-washed away like most of the complaints on this forum.

      THIS IS A VERY SERIOUS ISSUE. THE REPUTATION OF YOUR COMPANY DEPENDS ON IT.

    • RE: A few questions about the Halo

      @salmanmunawar said in A few questions about the Halo:

      @fonix232 I totally agree with you on the Facebook. I don't use Facebook and don't attend to join it. How is joining Facebook group going to solve these issues?

      I am so glad I am not the only one raising these issues.

      It's not going to help, and it's only muddying the waters - you report the issue here, you get directed to Facebook, you report it there, and they can claim it "got lost" and that's why it is being delayed.

      Halo is a great projector but it has issues that can resolved with software updates. I didn't even know about 32bit and 64bit issue you highlighted but that can resolved with software update if xgimi cares for it's customer needs.

      The 32b vs 64b issue most likely comes from the BSP they received from Amlogic - the SOC manufacturer tends to limit the default BSP to 32bit even on their latest devices, and the device manufacturer needs to finetune this.

      Luckily, Xgimi did not disable the kernel config exposure during runtime, so I was able to grab a copy and verify a few things, one of them being that it's indeed targeting armv7l instead of aarch64/armv8. Which will be a big issue - as I said for example I'm unable to run Plex Media Server on it, which only has builds for the Nvidia SHIELD TV. I bought a portable projector so that I can grab it and go to a park with friends, but Plex does not support sync for TV devices, thus can't easily make it work in circumstances when there's no WiFi.

      I could buy a SHIELD TV Pro, but that would add extra volume (and power needs) to the overall device.

      HDR issue

      HDR is a big one. Top reason I bought Halo. Even worse xgimi disabled in the last update instead of fixing the tone map. Everything plays in SDR especially from the Android TV apps. Halo homepage still says HDR decoding it is false advertisement. I was able to tweak HDR when connected to PC by playing with image setting from Nvidia control but that totally screwed up SDR content.

      I completely agree. I don't mind HDR being disabled if it's not working.

      Another thing that I noticed - the battery claims are completely false. The battery in the Halo is a 12.6V unit, made up of three 18650 cells - each of them 4.2V, so connected in series. But the packaging also claims to be 5400mAh - which is impossible for a 18650 cell, the largest ones are 3500-3600mAh at most, and those can't safely power this device. Since it needs a 90W charger, I'd presume at the 12.6V the battery provides, it would need at least a 10A continuous discharge rate to be safe (and as someone who has a bit of technical expertise in the field, 15A would be ideal due to overhead and sudden power spikes e.g. when the projector light turns on in standby mode). Given the price of 18650 cells that are capable of 10A discharge and have 3000+mAh capacity, I doubt they were used as such. But the 17000mAh claimed battery capacity still doesn't add up, even with knowing the energy density, which is 59.454Wh:

      • At 3.6V (which is the nominal battery voltage for Li-Ion cells), the capacity is 16500mAh
      • At 3.3V (which is most likely the board's main operating voltage, as it is for most electronics), the capacity is 18000mAh
      • At 5V (which would be the "powerbank output" which most likely doesn't happen, since the board has an internal LiPo interface and power regulator) the capacity is 11890mAh

      No matter how I'm looking at it, the capacity simply cannot match the advertised one.

      @wincore Hi, good day. sorry for the late reply. Hope you guys had a nice weekend. 🙂

      But I've checked all the issues here. 😞

      1. battery percentage. As I've mentioned before, Halo needs a small part to test how much battery left. There is no way to get the data, even the rough battery percentage needs to be tested as well, so to display it at the home page, this small part is to test the data, since there is no way to get it via software. That's why. Appreciate your understanding.

      Ari dear, you can keep repeating this, it won't make it true. Somehow you already report battery percentage - otherwise the updater wouldn't cry below 50%, and the battery icon on the home screen wouldn't work!

      1. Sorry to say this, but it's the truth, Halo is running the official android tv system, which is from google side. Google would update their own system regularly.

      And again, untrue. Google has already released not just Android 10 for Android TV, but there's an Android 11 preview ongoing right now! And Google releases security updates for TV on a monthly schedule - I should know, since my day job is basically developing an applications framework for my company's various channels, and I can clearly see the statistics, including security patch updates.

      The reason why you're not getting security updates is because you're sticking to Android TV 9. Update to 10 already, and we will have monthly updates. Even better, start open sourcing your work, let the community help!

      1. For the focus issue, part of Halo lens is made of resin materials, it gets softer in warm environment, so the focus would lose a little as the temperature goes higher, that's why we suggest to focus after 20 minutes using. Or turn on the dynamic focal lengh compensation-- help to focus on the back ground.

      I monitor my device's temperature, and it doesn't change considerably - in fact I keep it turned on 24/7, with the projection part disabled (so it's awake, but dark). However automatic refocusing - even if it's not needed since the image is crystal clear - does happen randomly. Sometimes my Halo can go for 3-4 hours without refocusing, sometimes it happens every 10 minutes, regardless of heat.

    • RE: A few questions about the Halo

      @Ari why do you have a forum if you want to communicate on Facebook? I think that's quite unprofessional. Nonetheless, I joined the group.

      On the other hand I'd have another request. Since you base your software on Android TV, which is running on the Linux kernel, which is covered by GPLv2, I'd like you to publish the source code for the kernel itself, and any other GPLv2 covered bits and pieces of the Halo firmware. And if possible, a full stock firmware image of the Halo as well.

      Also, is there any chance that the next update of the Halo would be compiled for ARMv8? The SoC in the Halo (Amlogic T950X2) is a 64 bit SoC, and should support 64 bit software, yet the whole system was compiled in armv7l mode only. Android is slowly transitioning to 64 bit only applications (a bunch of software is 64 bit only already!), and releasing a product limited to 32bit severely impacts the available apps. I for one wanted to install the Plex Media Server designed for the Nvidia Shield, however since it's armv8/64bit only, it cannot be installed...

      @Ari said in A few questions about the Halo:

      1. I understand your request, but it can be added due to the hardware limits indeed, the projector needs a small part to be installed to test the battery storage, that's why it shows the "battery" instead of battery *%.
        We can't just ask all customers to send the projector back to China and disassemble each one to add the parts, so we'll try our best to work on the software support, make it more accurate to show the battery on the screen. Appreciate your understanding.

      Except the hardware you're talking about is already in place! How else would you be displaying the "rough" battery percentage? Some sort of measuring must be in place for protection and such - all I'm asking is that you display the percentage and not hide it.

      1. Projector is different from other devices, there is no specical security for it. 😞 But we'll always there whenever any issue happens. And some issues can only be fixed in the firmware update, not like the regular update from phone or PC.

      Google releases security updates to Android TV (regardless if the implementing device is a full-blown TV, a set top box, or a projector).

      And what is this BS about the "firmware update" being different to "regular" updates on phones and PCs?

      1. The battery limits is original setup to protect the system, appreciate your understanding.

      Again, I get it, but those things can be changed 🙂 All I'm saying is, that based on user feedback, you could optimise the required percentage of battery capacity for an update.

      1. it's from the system setup as well, we can't take every projector for the same situation, appreciate your understanding.

      No, this is a SOFTWARE issue. And apparently it only happens with a handful of devices - my laptop, for example, had no problem reconnecting to the projector, but a HomeAssistant system I'm running (it's a Python app running on a Linux server, connecting via the same standard ADB) has the "forgotten keys" issue.

      1. Thanks in advance

      For the other issues, please email to service@xgimi.com, attaching the related pictures or video, I'll check it for you. 🙂

      How could I make a video of HDR not being available, when I can't roll the update back?

      The only issue listed that I can actually capture on video is the volume setting, but that should be obvious for you in the factory too - just turn a Halo unit on, long press volume up/down and observe that nothing happens, you need to repeatedly press and release the volume button for it to change properly.

      Also, any chance you could do something about the spam on the forum?

      It's incredibly annoying. I keep reporting it, but nothing seems to happen. If you need help
