Would it be possible do modify the Photon Q's battery at all? Like replace it with a RAZR MAXX HD's battery? I can't find dimensions on either battery or anything like that.
I was also wondering if it'd be possible to maybe take apart a battery (perhaps two Photon Q batteries) and somehow put them all in sequence and have it work like that. I'm a noob when it comes to these types of things. Any help is greatly appreciated!
You would have to get the measurements of both batteries and compare the sizes to see if the RAZR batt will fit. It looks to be the same voltage and chemistry.
You cant use multiple cells without special circuitry for charging. The best option is to find a larger cell of the same chemistry and voltage then mod the phone to hold it. Also, you would probably have to sacrifice a working battery to get the connector.
I added a larger cell to my Motorola Triumph

It's not easy to get that info, but looks like the RAZR battery, altough surely electrically compatible is not the same size.
Razer's one is 1.5 cm longer, and is also narrower.

Well, surely you can't put two "smart" batteries in parallel from the outside, but it's feasible opening the battery and connecting properly the cells, internally.
But this must be done by someone who really knows what should be done, to avoid risky situations.
You can connect multiple cells in parallel but it's not a good idea without a proper circuit to charge the cells. Over time the cells will need charged at different rates.

On small batteries like the one you can find on a cellphone "Proper circuit" could be just a couple of resistors to balance the "neighbor" cells.
I'ts way different on bigger batteries, like notebooks' or electric cars' ones.
Given the increased energy stored (and the increased risk) in the latter cases the charging circuitry checks every single cell, not the whole battery as happens on cellphones.
So doubling the capacity of such batteries is a completely different matter, a complete redesign of the charging circuitry (and battery firmware) is needed.
Alright, so I'm pretty sure I've this all figured out except for one thing. What the crap is this green..... thing on the back of the battery? It's like superglued onto it and I'm thinking it's an antenna of some kind, perhaps for NFC.
BUT, I can basically just connect the RAZR Maxx battery like this to mah phone I'm thinking. (see image)

Wiring a different battery is definitely possible.
I did it on a HD2 clone, using a Mugen battery meant for the Palm PRE.
The hardest part is to find a battery with the correct dimensions, usually find the right one is just matter of luck, given is hard to know the exact dimensions of a battery before buying it.
There's finally an extended battery (3800mAh) available for Droid 4.
(Droid 4 comes with the same EB41 battery as Photon Q).
So there's a battery that should fit (apart from its thickness, obviously).
The main issue is that there's no back cover for Photon Q to fit this battery.

We need 3d printer for back covers!
Or just wait a few month, I think that the back cover will come for the XT897.

The main issua, as usual for the mugen batteries, is the price.
89$ is more than what I paid the whole Photon Q.
Or, if you prefer, is 15x the price of the original extended motorola battery I'm using on the Phonton 4G
i just wrote to mugen power an email and asked if there is the possibility for a extended battery, as the droid 4 battery fits in the photon and only a bigger backcover is needed. this is what they replayed to me:
Thank you for your email!
I will pass it to our technology and marketing group to see will them make the cover for photon Q.
Will let you know later!
Please contact me if you need any additional info.

Just got a Photon Q so I would certainly love if they made a back cover but am doubting they will. Thought of just buying a second cover on ebay and cutting it / using some epoxy to make my own with the Droid 4 battery.
Dual Battery Photon Q
I know, seems insane but I've been running my phone like this for the past year and have even made a second one which is also running fine. Reason why I did this was because I'd bought a Photon Q in the summer of 2014 (previously with Verizon). The phone was brand new but the battery has been on the shelf so long that it was crap by the time it got to me. So I went and bought a replacement batter on Amazon. It already being a two year old phone, the replacement batteries went for only about $8. So I bought two. Upon receipt, I inspected it an thought of possibly soldering the two together to see what would happen.
Initially, I soldered the primary contacts of both batteries to each other (including the PCB), which didn't work. On my second attempt, I disassembled the housing for the PCB and soldered just the leads of the cells together and kept the PCB of one of the batteries. It powered on and worked properly. In fact, with two batteries, it seemed as so the phone worked faster than it did prior. I'm assuming more stable voltage.
Anywho, if anyone wants a 16 hour Photon Q, this mod works. The only thing that's off though is the battery meter. Since I don't know how to reprogram the PCB, the phone will hit 3% battery life after eight hours of use but will continue on for another eight hours. I've been using my phone like this for about a year now and it also seemed to have learned the new battery life. In recent days, the phone would actually shut off soon after the 3% warning. The second phone came into play because the touch screen stopped working. I tried to fix it but ended up breaking my phone instead.
I know I know. I'm crazy for allowing a lithium cell to be that closely exposed to the atmosphere. Whatevers, yolo. Anyways, the antenna is sandwiched between the two cells, back cover chopped up with a razor, and if you're fans of the car dock, you can take off the top layer, chop off what you need to accomodate the battery, and glue the remainder of the top layer back to the base. Like a glove!

Hi, I was how hard it is to replace the battery on the photon q.
Sent from my SGH-i927 using Tapatalk 2
I would say next to impossible - even if you did crack the back open and "replace" the battery with a bigger one (feasible), you would have to put a bigger cover on it - as I assume you want to put in a larger battery?
I think they make one of those cases that has a battery in it for the Q... Other than that, I would say carry around one of those emergency recharger thingys.
Battery can be replaced easily, it just needs a T5 screwdriver and something thin and plastic to remove the back cover (of course, you don't crack it), if you want just to replace it with another stock one.

Re: [Kernel] arrrghhh's kernel!
The only thing that could make problems is that the nfc antenna is placed on the baterry. The rest is really simple, just two t5 screws and the back as said before
I guess I assumed he was trying to replace it with a physically and capacity-wise larger battery...
Obviously you can replace the battery with the same battery... lol. It does take a bit more work than a 'normal' battery replacement, but it's certainly not out of the question.
Now I would be interested to see how someone shoehorns in a larger battery!
actually what about a combination of the two? would it be possible to drill 2 micro holes in the cover and connect a second battery in paralleled to the first? (like i do in a n ebike, just soldier 2 thing wires and connect them the phone 's contact. ), i'll attach it to the cover somehow maybe via velcro. this way when it will be charged, both of them will be charged.

You can't just put two batteries in parallel without additional circuits to prevent one sending current to another (which will happen whenever their voltages are not equal and is like shorting the battery (see Kirchoff's laws), because the internal resistance of the battery is low when charged). And then you have to secure the same thing for charging.
Also other issues like not knowing the current state of the both of the batteries etc.
I someone would be to "mod" the cover, I'd suggest checking out on RAZR MAXX 3300 mAh battery (the phone is 4.3"). Can't find the size of RAZR MAXX EB40 battery anywhere
Also looks like somebody did that for Atrix HD (http://www.youtube.com/watch?v=0jql0jxpBpA), but that is using EB20 battery like the original RAZR, we have a different one (strangely, named EB41).

The NFC antenna comes off pretty easily.
Will it be possible to mod by screwing the 2 metal pins down to the position where EB41 was originally connected, then housing the similar looking but ordinary after-the-market batteries not EB**?
Then, we can easily replace batteries on the go.
AW: How integrated is the battery?
I have to say till now I am comfortable with the built in battery. It lasts a normal workday, so no problems.
But as always bigger battery would be better. Personally I wouldn't put another back on to increase battery lifetime, but exchanging the original one with a stronger one (maybe with some small 'mods' inside the original housing) is a way I would consider.
So if anyone has news on increasing lifetime without to strong mods I would appreciate suggestions.
Sincerely

We were looking on the size of RAZR (XT910/XT912) EB20 battery, it's sized:
96 x 56.5 x 2.5 mm and the MAXX battery (3300 mAh) is just thicker. Unfortunately, Photon Q battery is sized cca. 71 x 46.5 x 3.0 mm (measured roughly, didn't find it on the net). That's 1 cm overlap on side and 1.5 cm overlap on lenght, won't fit there, unlike on the Atrix HD

Got it about a week ago. Came with a star bit screw driver that was the wrong size. I was at work so I just broke the 4 little plastic corners to remove battery. Had to take off some of the white plastic covering the battery to get the NFC coil off.
It's lasting twice as long as the old stock battery. Lasted 8 plus hrs as a computer. Clean install, downloaded apps, setup, and nandroid backup etc.
Use as a Media Device, and a "Phone". I think it was worth it!
Is it exactly the same size? Also what country do you live?

How much screen on time do you get? If it is over 6h, that would be very good.
I received my battery a few days ago, and a nice toolkit from Amazon yesterday:
www.amazon.com/gp/product/B00D9O3QBO
I had a lot of trouble prying the phone's rear cover off, but fortunately got some help from my teenage son. We used this excellent video:
https://www.youtube.com/watch?v=x2YVBJqA1do
Better prying tools would have been helpful, although my toolkit is excellent in all other respects. I think that the video omits a 14th screw which must be removed (after the rear cover is removed), near the center-bottom.
On to the matter at hand: I replaced the battery on my spare phone, which runs stock ICS and some (but not much) software.
Since some of the better-regarded battery benchmarks wouldn't install from Google Play, I used Battery Benchmark ( https://play.google.com/store/apps/details?id=com.batterybench ) on that phone, prior to replacing the battery. From a full charge, after 20,121 seconds, there was 25% charge remaining. Battery Benchmark said that it detected a cheating attempt.
After replacing the battery I ran the same software. Again it only made it to 25% discharge, saying that it detected a cheating attempt. We made it a bit farther, to 22,734 seconds. This is only a 13% improvement, but it seems to me that the screen brightness (100% with the new battery) had been dimmer with the old battery; perhaps one of my kids or I increased it during the intervening days.
It's too much of a hassle to swap the batteries and go through this testing again. I was hoping/expecting at least a 50% improvement, and perhaps that is really present, but is "hidden" by my sloppy testing regimen.
It certainly takes a long time to fully charge this battery, but I didn't run any comparisons.
I hope this helps someone; if you order a battery and repeat this exercise, I recommend setting the screen to 100% brightness using both the old and new batteries, prior to running your benchmarks. If it's easy for you to run an out-of-the-box ROM (stock or custom, but with no additional apps installed), that would also yield more reliable test results.

If you have a screen benchmark that you'd like me to run, then I'll be happy to do it with the new battery, using stock ICS. Swapping batteries was pretty time-consuming for me, so I'm not willing to do that again. But we can compare my results with the new battery to your results with your original battery.

Wow. That seems like outright fraud. Did the seller have any response (assuming you contacted them)?
yes I contacted the seller. I want full refund. Under the label is the same battery as original photon battery.
Only a very high quality battery manufacturer can increase the output of a cell of the same physical size. Motorola & other OEM manufacturers would have built batteries with the max capacity possible for the given space.
Unless you find a way to increase the physical size of the battery, you won't get any improvement out of a 'cheap' replacement, most likely a reduction in performance.
If it's cheap, and from a questionable manufacturer/supplier, it will be rubbish.

Hey guys,
I was looking into extended batteries for the Photon Q and noticed that the Droid 4 uses the same battery as our phone. Is it possible to use one of their aftermarket batteries?
I want a slim battery (not interested in making the phone bigger) and this one shows the best results from the D4 forums
Our original battery has some green tag on it as seen here:
http://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/ECQAAMXQUmFSjm2l/$_35.JPG
Is that just for NFC or something else? I don't mind losing NFC if that means I get more battery life
I got the mugen power battery to fit by removing some plastic and the back of the case, and of course NFC. Problem is it would get hot and slow down too often. Maybe that phone, maybe the battery, not sure, never tried it in another xt897.
I went ahead and ordered this gold slim battery
I'll be happy if it's even 10-15% better than a fresh stock battery
I will report back with my findings. In my current usage with one of the latest nightlies, I barely get 1-1.5 hours of screen on time when on mobile data and about 2 hours of screen on time when on wifi
While I've had decent luck with the gold batteries, they are actually just a factory Motorola battery with a shiny gold wrapper put on them. With that said though, at least from the ones I got they seem in every way to be genuine Motorola batteries, so still a good deal. I ended up getting a Mugen too and am working on making a case. I've got one molded up with some bondo but think I might end up trying to make one with super glue and baking soda like another poster did to make it more durable. I can still fit it in the vehicle dock by filing the USB port holder on the dock down a little bit.
If anyone uses the Mugen and happens to use Tasker, I wrote a tasker script to attempt to get an accurate battery percentage from the voltage readings and then update the OS if anyone wants. I also wrote one to keep the keyboard backlight more like the factory ROM instead of following the display backlight like it does in CM.
Just an update. Installed the battery today. I did partially peel off the gold sticker and it was all silver underneath. I know in other threads, the gold battery was reported to be a fake battery, or even stock battery with a new wrapper.
Initial results are good, but it's too early to tell. I will report back with updated usage. So far I'm not even sure battery stats are being reported correctly but it's a drastic increase in battery life.
So the gold battery has mixed results. The first few days I used it, the battery seemed pretty good. About 1.5 times longer than my shot original battery. However I noticed this battery does weird things in reporting numbers. Many times it will report 20% and then drop drastically fast to 0%.
Overall it's a decent battery but certainly not the capacity on the label. I would think a fresh stock battery would perform similarly without the weird drop off.
The biggest difference between my the gold and old stock battery is that it tends to sip power better. When the phone is not in use, the battery won't drain as fast. However when in use the battery drains just as fast. Maybe a little slower with gold, but not a huge difference.
My only concern is sourcing good batteries for this phone now. Even if I found a new stock battery, the unit itself has to be at least 3 years old. I'm sure motorola doesn't make new batteries for this phone anymore...

Lenmar still makes batteries for this phone (EB41, fits Droid 4 and Photon Q). I ordered 3 about 6 months ago and there was a 2 month lead time, so they obviously were newly manufactured batteries. I keep a spare in the fridge, the ones in my Droid 4 and Photon Q perform like new as expected.
Note: it won't come with the NFC antenna, but with great care this can be removed from the old battery and reattached.
I would like an extended battery too, but only if it came with a nicely fitting cover. Mugen makes one for the Droid 4 which could be used with the Photon Q, but they don't make a corresponding cover for the Photon Q.
Hope this helps.
P.S. which ROM do you guys use on this phone? I'm running CM 12.1 and it is fine, but when I have a few apps running like Google Music and Navigation, the phone gets super slow due to lack of memory. Under 'Apps -> Running' it shows 450 MB used just for System! I guess 1 GB phones are just passe at this point--or is there a better way to get more life out of this phone?
Cheers,

Alright. Just like what happens with many smartphones, third party sources have started releasing batteries with a little more juice than the Original LG Batteries of 2800mAh. I have to admit it, i was kind of counting on it because it happens a lot of time. But how reliable could they be? Would NFC work with them? Will it make our phone explode? From 2800mAh to 3250mAh is 450 more juice to drain. Has someone tested it? I've posted the link and a couple of pictures.

I have tested for two day and although I haven't gotten any numbers to prove it...the battery works great. It does last longer with the same usage...but I wouldn't say that the difference is huge but it does have a little more endurance. I'd say that if you are looking for an extra battery...this is not a bad choice especially just to keep as a spare. Everything works fine as well.
Also...it may take a few cycles to get the battery calibrated...my first discharge I was disappointed because it dad extremely fast but after letting it run down and charging it a few times it seems to last a little longer than stock. I'll leave the battery in for a while and if I get time to collect screen on before I charge it I will.

I think one would see a real difference if it had 900mah ane up more than usual. I was kind of expecting for that though. Hahaha. But i have the feeling they will release an eveb bigger one. Something like 4000mAh+ but you have provided us with great detail. Thank you. If you have the SOT in the future feel free to provide if
I doubt we will see anything much larger in the same size. Batteries have limited capacity/cm3, and LG, being one of the best and largest battery manufacturer, maxed out on that value. The problem here is the physical size of the battery cell...

Actually Zerolemon emailed me and said they are working on a battery for the G5 as we speak. They can be miracle workers lol

They managed to do that by replacing the back cover with their own "case", including an extra-size cell. The G5's different battery removal mechanics make it a lot less viable option, especially adding the bottom module (which houses not just the USB connector, but speakers, microphone, and some antennas) as a cost.
My original comment was directed at the allegedly 3200/3250mAh cells popping up for 5-10$ a piece. There's a reason why official LG cells are 25$, and these after-market ones cost less than half of that. Sure, LG needs to cover the development costs, but I'm pretty sure the after-market ones are so cheap mainly because of corner cutting. And that comes with extended hazard. But if you feel like ruining your 600$+ phone because you went cheap and paid 10$ instead of 25$ for a battery... It's your call.

They could create a module similar to the Cam+ that has an 'extra' battery in it. Maybe slimmer but further up the case.

I have been following the forum site for lg g5 modules development and untill now no one has has stepped up with the idea (no one that would have the knowledge to start building a module for the g5 at least)

Check out this thread I did for the Sensation (ages ago). It's not relevant to this phone, other than to say that you'll recognize some of the labels:
http://forum.xda-developers.com/showthread.php?t=1753726
The TLDR: Actual mAh was was tested reliably (external discharge, outside of the phone) and batteries with the same label style as the two linked in the OP actually had roughly 30% and 50% of their stated capacity, and much less than stock.
I've got a G5 coming this week. I wouldn't be against doing another thread like the one I did in 2012 on the Sensation, if there's demand.
I have this one coming, so i will let you all know what i find. There seems to be mixed reviews, and even my Stock Battery had to be calibrated up/down charge for 3-5 times before i had good life.

The mixed reviews are in part my fault. I'm one of the reviewers with that battery and for some reason Amazon will not post my updated review, I've tried 3 different occasions to post follow ups but they won't post.
What I learned with that battery is it works, only it does give me the invalid battery message and the phone shuts off but only if I reboot the phone at 100% battery life, upon booting the phone reports 50% charge and shuts off. You have to restart it a couple times until it's used a percentage or 2, then it boots fine. I emailed the seller about it and they responded with the cells are tested and they only use quality parts, they sent me another battery but that one does the same as the original. With the issue with the note 7 and other phones/chargers I stopped using the battery. It might be perfectly safe but I can't determine that and the risk is not one I am willing to wait and see. Here's a link to another topic here on XDA where I responded about this battery.

So, after the first full charge and discharge to 11%, I'm getting very good times better than stock. This will probably increase with a few more charging cycles. My opinion is this battery is definitely more mA. I will review more when later.
Gentlemen,
I have successfully swapped out my battery in my Nvidia Shield Tablet K1! I was so excited about doing it! I wanted to get some practice soldering, as this was my first time, so I tried it out while swapping this battery here. I don't think my job was great, just adequate. I'm going to document the process here so that you guys who want to try can benefit. :good:
Without further adieu....
Since I couldn't post what I wanted to here, I did the write up on Google Photos instead. Here's the link to the pictures and my instructions to go along with them.
Link to gallery of photos + FULL WRITE UP here - https://photos.app.goo.gl/4jlzvnHpoBXwffOn1 :highfive:
I'm a little disappointed that the cells don't hold advertised charge. Take a look at my picture here from AccuBattery with the "new" swapped battery installed. It's basically only 83% effective out of the box.
Please give me a thumbs :good: up here or send me any gratitude if you felt this post has helped you in anyway. I really like this community. :laugh:
Shoot me any questions you may have on my battery swap on this thread here.
Cheers!

Updates?
It's been a couple weeks since you posted this battery replacement, how has your tablet held up? Have you noticed if the battery charge levels have regularized, or is it still operating at a lower capacity than advertised? Also, any power quirks to note?

Hey JP,
Thanks for the questions. I'd be more than happy to answer them. The tablet has held up great! No weird issues or problems since swapping out the battery. The levels have regularized, as it were, around 81% of stated capacity. That's around 4100mah, so it's still operating at a lower capacity than advertised, unfortunately. No power quirks to note. :good:
I would say, that to anyone who's going to undertake this, it's not worth it unless your battery is about 50-60% of stated value (5100mah). I had about 75% in my old battery and it wasn't worth it to gain only 6% or so. It's so sad that there is no OEM Nvidia Replacement Battery for your Shield Tablet.
THat's why I think so many people are selling this tablet now -- the battery is finally giving out after 2-3+ years... The best thing that you can do if you want this tablet to last another 2 years with awesome battery life is to buy another Shield Tablet as "NEW" as you can find it. You might luck out if you can get a used original Shield Tablet that has a B01 battery installed.
That's my two cents anyhow. Kinda sad unfortunately, but the swap is absolutely working well...shame it's just CRAP batteries to replace your nice OEM one with!
-Elo
The results speak for themselves ?? Unless your battery is completely shot, you're not getting the whole 5100mah. I'm getting about 80% after a month. Not getting any better! Considering selling this tablet for the Huawei Mediapad M5 ... So sad.
Hello there
I tried and probably was successful swapping the battery (the good one) with another korean one <<[V071] 3.8V,3.7V 5000mAh [3565153] NTC; Polymer lithium ion / Li-ion battery for tablet pc,POWER BANK,cell phone;GPS>>. The oem one suddenly didn t charge at all.... after a lot of reading decided to order a cheap one to check if battery was the problem.
It shipped two days ago and went straight to an electronic guy i knew for soldering the new battery to the old controller. It came alive!!! Had some problems with the solder since the pads are electropods and need another method with a heating pistol or something. Never the less we solder it . What i ve noticed.....
1. I didn't measure the battery but it lasted the day with gaming.
2. After 20 mins of playing the tablet was way to hot than the previous battery to a point that i couldnt handle it...felt discomfort....the screen was warmer also.
3.Battery went to 10% and that s it.Since then i cant charge it anymore...stays at 10%
Do you think its a problem with the battery board and as many batteries i change ill have the same result?
Thnakyou in advance
OG Shield Tablet
First: Thanks for the tutorial! The photography/documentation was very helpful and allowed me to do my own swap.
I decided to try the same surgery on my OG (pyro) Shield Tablet; The battery capacity had fallen to about 2000mah and it was starting to run a bit hot so... it was time.
I used a combination of your notes and a YouTube video found at...
(can't post external links on new accounts, but the video is called "How To - Nvidia Shield Tablet Battery Swap")
Notes
I used a new-old-stock Padphone battery, Asus branded, labelled 5100mah @ 3.75v
The white "whatever module" found on the positive lead on the K1 is found on the negative side on the OG. Still need to keep it, but keep it on the negative side.
Snipping the battery leads (rather than prying them off) from the original battery<->control board gives you more/longer material to work with (such that you don't need extra wires). Effectively this gives the controller board longish "tabs" of its own to bridge the connection.
The metal lead sandwich is a little trickier (than wires) in terms of soldering jobs; definitely not my best work. Liquid flux helped a lot here.
Capacity is still working itself out (going to need a few full discharges) but it looks like it's going to come in around the 3800-4000mah mark; Not bad for a battery that has probably been sitting on a shelf for years.
That's about it. Everything else went fine.
Agreed on difficulty in prying off tabs - Getting the leads/tabs pried off the new battery's control board is a brutal task. I wonder if, with the longer tabs (created by stealing them from the old battery), one could just snip-off the new battery's board... and still have enough material to make the bridge (just over top of the welded-on tab remnants). Didn't think of that at the time... No reason for it not to work.
Anyway, thanks again for the guide!
No offense but man your soldering is awful!
Your photos were exactly what I needed to find a battery though! Here's a link to it on Amazon https://www.amazon.com/gp/product/B01DM29PTY/ref=ppx_od_dt_b_asin_title_s00
I just cut the tabs off the old battery to make it easier to work with the control board. The tabs are spot welded to small metal plates that are then soldered to the PCB. You can very carefully rip the left over tabs off then you can easily desolder the left over metal tabs leaving just the clean PCB to solder the new battery tabs to. The correct tool is a heat gun (Rework Station), but I don't have one so I managed with a soldering iron. (I managed to change the charging port with the same soldering iron, that was a *****)
The 'Unknown white thing" is a Thermal cutoff. If it gets too hot it opens, disconnecting the battery from the device. I posted a link to a replacement as a comment to the photo on google.
Note: The device did not turn on until I plugged the charger in. Apparently the control board needs the input to switch on the battery.
Thank you. We've had our K1 for several years now and to replace it with one as powerful isn't cheap. The whole family uses it for playing games and watching videos.
It's great to see that people are successfully doing this. Main thing is keeping that board in good condition, else all is lost, the tablet will not boot up. It's also sad to see that no tablet out there except maybe the iPads can walk toe to toe with the shield tablet performance wise. But I'm looking for a replacement and would love to know if I'm wrong...
I've got a shield tablet I bought about 4 years ago, and it's still going strong. But for you guys looking for a good replacement, I bought a Huawei M5, and it's the best tablet I've ever had. Much faster and more powerful than my K1. The last time I saw a brand new K1 for sale, the price was $500 U.S. Theyre nice, but... But I do have three old nexus tablets that need new batteries, so this info goes a long way in helping for those as well. Thanks
There are a couple options

Great to see some people still getting benefit from this tutorial! A lot has changed for me and "tablet" Android gaming over the past year. Basically my journey went like this - Nvidia Tablet K1 => Huawei Mediapad M5 => Honor Note 10 => Huawei Mate 20X.
Now I love the 8" form-factor, but couldn't find the power to play all games that I wanted for several years to come. I could have gone with the Xiaomi Mi4, but it was a little slower (in RAW processing power) than even the Mediapad M5. I like the Kirin set of chipsets, even if their GPUs aren't as great as NVidia's or Snapdragon's, but they have great optimization for their hardware.
Also the Mate 20X is a little more portable while still having a "somewhat" big screen compared to the tablets. If I was really hardcore about gaming on a tablet, there's little reason *NOT* to go to Apple, as they JUST refreshed the iPad Mini, but I love Android too much to ever consider doing that
Anyhow, I'll wrap up this long post saying the main reasons I switched, even though the Shield Tablet K1 was one of the best Tablets I have ever owned -- It came down to battery life. I couldn't get more than 2.5 hours of screen on time for most games, whether they were through GRID, native Android, or emulation. My Huawei Mate 20X gets about 9 hours of screen on time while gaming, and that's on a BAD day (most time I get like 10 hours or so). So, a massive 5000 mAH battery with a 7" inch screen is a win for me, while the processor is super fast, and the screen is good. Plus, being able to play certain games on the Play Store (like Final Fantasy XV Pocket Edition) that I couldn't on the Shield Tablet K1, was awesome. That's why I left the Shield Tablet behind. :crying:
Enjoy those Tabs while you can! Shame that Samsung discontinue the Galaxy Tab S series 8.4 inch devices... would've bought that instead last year.

I changed mine out as well. Found a comparable sized 6000mah battery, 3.8v, on AliExpress. It still says it's a 5100mah on cpu-z as I reused the old battery's circuit board, which I assume tells the device what it is. Not sure if I see a great increase but it is up and working. No heat issues, other than gaming which it always got warm gaming something like Half Life or Oddworld.

How as your battery life been since the replacement compared to stock? I think my original battery is starting to fade, it gets relatively hot and loses charge fast now on the original battery. Do you have a link to the one you installed? Thanks.

I bought this one, https://www.aliexpress.com/item/32807442206.html?spm=a2g0s.9042311.0.0.78584c4dqP3CHO. I really can't say I was super impressed but it's not dying fast, which I believe it was. I took it and my son's, he almost never used his but just about as old, we have the original models with the stylus, anyway I put them side by side with the same 24 hour rain YouTube video and they lasted about exactly the same. I can't remember how many hours of that YouTube play they lasted, maybe around 5-6 hours straight. It's been a while since I did that experiment.

There are two connections from the original battery to the battery logic board. I pried them off and just soldered the two leads from the AliExpress batt and used some tape to keep it in place. Plenty room for this new batt. I did not dissect the new batt to remove the board it comes with. The tablet does get warm gaming more intensive games, but not unlike it did prior to the batt swap. Pretty much the back gets warm but I'm not sure that's the batt or the processor. I did see some heat sync paste back there but no real metal for it to dissipate to. Doesn't get any warmer than my LTE model I haven't changed the batt on.
---------- Post added at 03:48 AM ---------- Previous post was at 03:42 AM ----------
And when I swapped the batt I had to plug the power cord in to get it to come on. Then I unplugged it to completely drain the batt. I read somewhere to do that the first time then recharge, leaving it for a good day. I still go in my settings and select no more than one background process and a custom power setting with 1 to 4 cores, 1 when there's little demand, and I think I limit my fps to 30, without looking. I'm writing from the very tablet now.
What about Nintendo switch batteries too thick?

I ordered this battery 2x a week ago because I have 2 original Shields and waiting for delivery now.
Will report here after I swapped the original battery for this one.
Yeah, I saw someone on eBay selling that very battery for over $30. Probably buys them like I did and sells them for more on eBay.

I'd say that the most important item in that tablet, if it is inoperable, would be that battery logic or protection board. It has 4 wires which I might know what three of them are for but not the fourth. I think a green wire. And because I reused that battery board, it will still show up to the tablet as a 5100mah battery, no matter the size you connect to it.
I replaced the battery (the one that was posted above from Aliexpress) of one of my Shield Tablets and it fits nice.
Only precaution you must take when removing the back is that there is a flatcable connection between tablet and back for the stylus recognition.
When it breaks no big issue just the stylus is not activated anymore when you remove its from the storageplace.
Also it is a delicate job to remove the small circuitboard on top of the battery because it is very tight packed with sealtape.
Don't desolder the 4 wires going to that board and just remove the board very carefully from the top of the battery.by cutting the 2 connections to the battery itself.
On the circuitboard it is written B+ for the red wire from the new battery and B- for the black wire.
Ré-attach the new wires from the new battery to the 2 terminals and wrap them preferably with shrinksleeves.
You can then store the circuitboard next to the new battery and cover it with duct tape or something like that.
Then press the back gently back to the tablet and done.
I paid USD 22,50 for 2 batteries including shipment.

I was wondering what those 2 other smaller wires are too. Must be for data only based on the small gauge.
What will the small grey wire be that you have an idea about?
I'm looking into getting rid of the battery altogether to run my K1 off USB power only. Battery had always been the K1's weakness. From the original battery getting recalled, to the crappy battery life even on my updated ST8 model battery, to running hot all the time, and now my ST8 battery is bloated too and looks pretty shady. I'm not sure I want to replace the battery anymore and looking for solutions to go plug in USB power only.
