I started having this weird problem the past few days. My tablet seems to become very hot while charging. It also runs quite hot when on wifi. As a result the battery performance seems to be degrading. Any light on this...our has anyone faced similar problem. A possible solution to this would be highly appreciated.

if you read the user manual which comes with the tablet ( pdf is also available on official website) they have mentioned it in manual that tablet can get hot while charging and using processor intensive tasks like wifi and games. They have also said that it will not affect the longevity of tablet or battery in any way . My tablet does get a little warm while charging and after heavy usage. i guess its universal

I wouldn't worry if the tablet was getting a little warm. But the moment i turn on the screen, the left side of the tablet. both back and front become exceedingly warm even without running any intensive programs. The issue started about 2-3 days back only. i never had this problem before.
While charging the tablet is literally quite hot, and like I said more on the left side.
I think I need to go to a service center to get it checked.

If the battery gets hot, the effects are similar to those of overcharging. You know how bad overcharging would be. So I recommend you to take a deeper look into the issue.
Taking it to service center is a good idea; but since the service center would wipe your tablet clean anyway, so why don't you check if there are any background processes that have been causing this acting up lately? Messengers like whatsapp/line, screen lock apps, weather and news widgets, adware/free games with ad are examples of the apps that would be taking background resources, you would like to check whether you have installed new apps like that.
Most background processes usually won't cause your battery to act up, except when they got stuck on something. You probably couldn't fix it by yourself so you would better track them down and remove them.
TasKiller is one of the app that could show you background processes. There are countless others good app for the same purpose.
My tablet has been on charge (while off) for almost 24hrs and still hasn't fully charged yet.
What gives?

Do you use the stock wall charger to charge it?
My tab was sitting on my desk in sleep mode. I picked it up and tried to unlock it and it seemed frozen for a moment, then let me swipe. It seemed fine after that. A few hours later I picked it up again and it was very sluggish and the back was warm and my battery at 15%. (it was at about 50% a few hours earlier) I rebooted it and it's fine, but I am wondering what caused it to get so warm. I know that happens when it's being used a lot but it was just sitting on my desk. There were no apps running in the background. Any ideas what could have happened? I haven't installed anything new in the last few days.
Are you running stock?

And we assume ICS (apart from stock)? But there are quite a few threads on the increased power-consumption on ICS (Stock and other). So might be some run-away process or service. What is the highest battery-user according to the device info? And how much? Has ICS gotten rid of the dialer goof-up for non-3G tablets?
P.S. Like the off limits (slap on the wrist) of the better half's tablet, same here :laugh:
Yes assuming ICS...my bad lol. It was more of a "tell me everything you've done lately" type of question. I have noticed increased battery consumption myself but that's why I switched ROMs today. If I lose a couple extra ticks on the battery in exchange for the performance I've gotten I can live with that
And yes I will lose whatever part of my body touches the wife's tablet. She's heard enough profanity in the last month as I got my feet wet hahaha!
Yes, stock ICS. Sorry for omitting that!
The highest battery user is the screen. I'm thinking maybe the tablet froze and I didn't notice it. Having the screen on constantly for several hours is probably not battery friendly. I'm concerned because it's still warm between the Samsung logo and the camera on the back. It's not hot or anything, just noticeably warm, and it's just sitting there charging. I'm not using it.
I have (or you can do it yourself) to delve in other threads, where they dismantle the tablet. Is it a P7500, or just a plain P7510? I thought that the 3G radio-part was about there where it still is hot (residual heat probably by now), but I can be mistaken. If this is a P7510, then I do not know what would be there at that location. It certainly is not the battery, that is much lower...
I will try and find what is about there, but other solder-happy soldiers must be able to tell you exactly what is located there.
Anybody?

A friend of mine had a similar problem with his galaxy s2 locking up and needing a long-press power reboot to get it working again on stock ICS 4.0.3. The culprit ended up being android os in battery stats, but the problem has not happened again yet. As for the warmth on the back of your tab, this is caused by the processor running at full speed for extended periods of time. If your screen is on, and you are interacting with it a lot, then you should expect the upper left back side of the tab to heat up and not cool down until you stop using it. This is normal... if it continues to stay hot for long periods of time after the screen is off, then you are probably not going into deep sleep mode because of a rogue app. If you are rooted, install better battery stats and CPU spy to do a little more digging. Good luck, I hope you figure it out and get your tab running the way you would like it to.
I figured out what it was. I'd seen the Ebook icon in my app tray and tapped it. It took me to the Samsung App store. I left immediately but that visit apparently installed "Samsung Push Service" which was taking 62% of my battery and causing 100% wake lock. What a POS! I uninstalled it and everything is normal again. Won't ever visit the Samsung App store again.
I froze that app. Ugly. Glad you worked it out!
I've had my new phone for almost two weeks now and noticed that it runs uncomfortably warm. I noticed this right at the start in fact, a few minutes after I first turned it on, but as the built-in apps updated themselves I knew that would heat it up. It still got warm afterwards though, even before I installed my usual apps and transferred my data to it. Just having it switched on and fiddling about with the built-in apps was enough to make it heat up significantly after about 10 minutes use.
I then installed Battery Circle which reported a toasty 43 degrees centigrade. This seems rather too hot for comfort and the battery drain is quite significant - it dropped from 100% to 75% in just under two hours of use (not totally continuous) of web browsing, BBC and Facebook apps etc so I wonder, is there a hardware problem with my phone or if it's just the 808 chipset that's prone to running hot and hence normal for this model? Overall battery life even with moderate use isn't exactly fantastic, either and rather worse than my old Moto G (2014).
I did Google it, but couldn't find anything conclusive, even on XDA, with quite a lot of people seeing this issue and an equal number not seeing it, so can anyone shed some light on it? Is the upcoming Marshmallow update with its improved power management likely to alleviate it?
Although I like the phone and the performance is very good, I might just return it because of this issue and get a different phone. Prerequisites are stereo speakers and a minimum of 2GB RAM for smooth, stutter-free operation, everything else is not so critical. Any suggestions for alternatives? I paid about £350 for it off Amazon and would like to spend about the same on a possible replacement.
Same here, just browsing internet for 10 minutes, and phone turns noticeable hot.
Android 6.0 installed yesterday, same hot issue in the new ROM ( bootloader locked, ROM stock, recovery Stock)
Purchased in Amazon (399 + tax)

I own MXS XT1572 (Indian dual sim variant) and it does not get as hot as you say... but yes, after 1 hour of internet browsing it does get hot enough to feel uncomfortable in hand. 10 minutes is something I noticed in one of my friend's Moto X Pure... and another friend has no issue with his moto x pure...
So maybe yes it can be a problem with half of the devices...
Well, good thing about 6.0 update is: temp is about 10degrees cooler from lollipop. I been doing the exact same thing and noticed the change. Pretty much constant gaming with full gpu use. Must be updated kernel or gpu. I'm hoping devs can look into this and come up with a rom/kernel to tweak these settings little bit more to make this device solid and put heating issue to bed.

That's great news.
Been using it over the last couple of days in this colder winter weather without it getting excessively warm. It looks like it's quite sensitive to the ambient temperature, so I wouldn't be surprised if it suffered thermal runaway on a really hot day and burned itself out.
Do you people recommends to send this phone to warranty with this issue?
Just using Chrome for 5 minutes and battery show 42 degrees (celcius) , i dont remember any other app doing the same thing
Thanks in advance

I was running the battery dead out-of-the-box due to Google shovelware. Disabling as many Google apps as possible and using a browser with an ad blocker has me ending the day at 45%. If you have any ad spewing apps, get rid of them too. Buy or find ad-free versions of your apps.
Hello everyone!
So I have been having these battery issues since April security patch. the phone gets really warm to the touch even by doing the simplest of things like browsing and watching youtube. Android OS keeps the phone awake 80% of the time and I am only getting 2-3 hours of use throughout the day. Restored the phone to factory settings(fresh start, nothing restored) three days ago and still the same issue. Android OS drains the battery life even though I made sure that only google apps are installed on the phone.
But today things got even weirder. I disabled Google Now and location services as a test and the battery drain and heat issues were gone temporarily. I was getting a great battery performance from morning to afternoon. I check my battery stats and I notice that Google services mysteriously drained 17% of my battery life and that it's been running for 21 days straight? That's impossible since I just did a fresh reset to the phone three days ago. I rebooted the phone and that "Google services" drain changed to WiFi instead?! That's crazy!
I contacted Google store support team and they have been really helpful so far. They offered to replace the phone with a refurbished unit, but I don't think I am ready to give up on this phone just yet.
Thank you!

I hate to recommend this, but sometimes things go out of wack after a SW update, so a hard reset would probably be needed. I would try that (just start from zero) before jumping into a refurbished phone that might have some other kind of issues. Have you tried a hard reset yet? I see that you did a fresh reset. Did you go through the recovery though? Not just the regular UI. I think it's better to clear cache, and every thing through the recovery (custom or stock).

I did it through recovery. I have cleared the cache and rebooted the phone several times the past few days. Nothing seems to help at all.

Wow. Maybe a custom ROM might help? Have you tried that? That's the last thing I would do. Good luck!
Not recommended but I just flashed January vendor and ROM and that has helped my battery life. I. Believe it is the security updates that kill our battery.

Is it a widespread issue? Like I said in my post, I saw the decline ever since I got the April security update. The May patch actually managed to make things worse. There seems to be something hidden in the OS that it's draining the battery and causing the awake issues. I haven't tried rooting the device because I lack the experience to do so. I will probably look into it on these forums, but at this point I have tried everything.
Disabling Google now helped a lot and it exposed some sort of a glitch with the stock battery monitoring app. I am not sure if it's hardware or software, but it's certainly not normal. I am tempted to just replace it, but I am afraid that this issue will just plague the new one from Google. I am really disappointed How Google handles updates on this device. I always thought that stock android is most stable version of android, but the software on my old Xperia Z is actually more stable than this. It never had battery drain issues and standby battery life was always great. The battery life on Nexus 6P is actually worse than the Xperia Z even though that phone is 3 years old.

I've seen a lot of posts over the months with people having the same problem we are. I came from a mid range LG stylo with a snapdragon 610. I would have 8 hours screen on time daily. Its sad that goggle cant get the same out of their own hardware. Also I have seen that the Note 5 and S7 Edge both get better battery life as opposed to our stock phones. For as much as people praise stock and look down on Touchwiz, they are doing something right over there.
But it doesn't affect everyone and that what puzzles me. Only certain phones are hit by these issues, while other people are getting excellent battery life. I have seen plenty of people post screenshots of 6 hours+ of on screen time. I am lucky to get 3 hours. I think Google should really invest in creating a better power management system into Android. Companies like Sony and Samsung built their own and the battery life on their devices always perform predictably relative to what I am seeing on this phone. I have never witnessed The doze feature kick in since I have bought this phone. Sony had stamina mode since 2013 and it actually worked.

Most of those people posting those outrageous number root and do kernel tweaks. I've gotten at most 6 hours SOT on stock without root. You are right our phones do all react differently to certain circumstances. I don't know if it's feasible to you ,but you should try rooting and trying out a few Roms some help others don't. If you aren't into Roms and decide to root try earlier vendors and stock roms and see it those work. I'm not an expert by any means just my suggestions.

Well, the fact that you are having great battery life proves my point. It's either that the quality control of the batteries used on these phones are terrible, or that the software or kernel are corrupted from factory causing these issues. There is no way to fix them by hard reseting the phone so far. I am going to try to flash a stock rom on this device and see what happens. Thanks by the way.
1) Are you rooted? If not, at least do that and install BBS in order to track down what's eating your battery.
2) Probably we'll run into a common problem / bug the last two months.
After unplugging the phone, it seems that the wakelock *backup* runs constantly, does not let phone get into sleep, and runs in the background while using your phone causin battery to drain faster.
3) About battery life. Comparing battery results between two users it has no point, unless you really now his usage pattern. Not only the setup, but which apps of them used most etc.
For example Facebook app is real battery eater. I've seen an hour more SOT without this app.
I can give several examples like this.

I jumped in and bought a K1 to replace my dying GPad GPE. After 3 days, this seems like a huge mistake.
The K1 is very laggy in basic apps like Play Store and Chrome, does not register touches very well and has terrible battery life. I even charged it overnight and didn't get a full charge. On top of that, I am constantly getting the screen overlay message any time I need to enable a permission.
What could be causing this? This tablet is so highly regarded I don't get it.

For charging you need a 2 or 2,5 A charger. Then it will charge (if it's not faulty) in around 2 hours. The screen overlay message is coming from the quick launcher (or how it is called). So disable it or give it the right to draw over other apps.
I don't have problems with lags or touches. Are you on the latest updates?

I am using the correct rated charger. This even happened when charging with the tablet off.
I am on the latest update. I waited to install my apps until after all updates were applied. The touch issues may be lag related. The back button almost always requires multiple touches. Keyboards often time register multiple touches or just freezes.
I am also noticing network issues. Apps report loss of connection when the wifi shows connected.
I hate to say it, but I am leaning towards returning this for a Samsung.

Also a recent owner of the k1. Running stock firmware (1.5) but with BitO-K kernel. The only thing I am experiencing is mediocre battery life, charges from 50-100% in under an hour using a 2.5A charger. The only thing that sucks, and this goes for android tablets in general, is the removal from 4.4 of the TabletUI. Seeing we're already at 7.1 and TabletUI is still dead, it looks like we'll have to fight to get it back again.

That lag is not normal. And my tablet charges from around 10% to full in about 2 hours. Maybe you should try a factory reset. If that doesn't help I would return it.
I won't buy a Samsung tablet. I would try a replacement. I own the k1 for a year now and I'm still very satisfied with. And Nvidia updates it. Which Samsung usually doesn't.
Don't listen to Nvidia trolls... ⬆
Your experience does not sound typical. Perhaps it's a hardware issue, but I agree with @edisso10018 that the first step would be a factory reset.
Wish you luck!
The Nvidia CPU is pretty good shame it's not the X1, It performs better then some of my phones with QC chips, Do a factory reset and see if the lag is still there, Battery life is poor can agree on that
My k1 is over a year old it is still playing games with no trouble yes a agree with the battery life but mine charges with no problems a have noticed a little slow down but am not running bit os updated kernel yet but a still rate 10/10 best tablet a ever owned.
Tablet is laggy, no denying it.

K1 here-- I don't run stock (DU 6.0.1), but I used BitOK for a while and realized its not very good. Switched back to stock kernel (from my ROM) and its more stable. You don't lose out on much anyway-- BitOK doesn't have features I want like voltage control. Examples of instability caued by BitOK: GPU was stuck at ~350mhz, would not ramp down fully to 72mhz. Also stock is smoother. You can still use adiutor to monitor and control a few things.
One more thing: be very careful when flashing blobs and other stuff in fastboot that it is for the K1 version and not OG shield! A lot of devs posting these things arent explicit as to which version. DTBs and Blobs are specific to the shield type-- one might work for the wrong tablet version, or it might brick it, or it might be unstable.
As for the Batery life I can tell you it does suck even on the best case scenario. There is no way around this as it is small and the large screen, as nice as it is, sucks a lot of juice. Lowering brightness helps somewhat but still I'll be lucky to get a couple hours of SOT out of it.
For the price its a great tablet, with a few small compromises, such as bat life, but thats the price you pay for great screen and sound at a cheap price. We are lucky to have at least a few devs still doing work with this device, and luckier still that nvidia is STILL supporting it with updates, even if slowly. They recently announced 7.1.1 will be forthcoming.
Mine was laggy too, I flashed stock firmware with my PC and now it's working perfectly.
Bought mine as a refurb and it works fine. I think you either have bad hardware, or a bad install. Try flashing stock and see if it improves.
Tbh my only complaint is with battery life, I switched to BitO to see if it got any better, the tablet is smoother with this kernel than stock but the battery is the same, I wish we had UV'ing, my favorite setting on any kernel, back on my N10 my battery could easily be improved 10-15% and the heat was reduced drastically, good binned ones could shave up to 200mV on some steps. K wish this was implemented

I just bought a K1 (discount price 169€) and I don't have this problem at all. Even if I use only 1 core (settings performance) for basic app it's smooth smooth smooth.
And the battery life is huge !!
For gaming tho I switch back ofc the performance setting.
:good:
I bought a K1 three weeks ago to use as a display for my phantom 4 quadcopter. I am very impressed with its performance. I'm not experiencing any lag other than at startup. Once it's up and startup is finalized I dont have any problems. The battery life isn't great, I'll agree there but hopefully it gets better with Nougat.

I bought a K1 last week to replace my aging Nexus 7, did a factory reset and still wasn't satisfied with it being laggy. Did my share of Google searching and finally stumbled upon a quick fix to try : disable Daydream. Since changing this one setting it has been very smooth since, no issue for lag or touch registrations.
Give it a try, might not help your charging but I did notice a much reduced battery drain while sleeping also.
My only other changes were to root, change the DPI to 240 and use the Google Now Launcher which compliments the display nicely.
I wasn't happy with it as well until I flashed cyanogenmod 13 and a custom kernel with overclock. Now it's a beast, battery is great, signal as well. And I also now have the option to OC the processor to 2.5 GHz before I play some more demanding games and then set it back to 2.2 or even lower if I won't need all the juice. Seriously, the stock marshmallow ROM sucks, I have only heard bad stuff about it. Also, the nougat update is about to come out so I'd give android N a chance, too.
About the battery life -- see which apps are using the most juice under settings/battery/. Some of them may be using more CPU cores, and have a higher frame rate than is needed. Go to settings/App optimisation/ and crank the numbers down. Next go to settings/Accounts and see the long list of things that want to autosync with you. Turn the autosync off for those you aren't using. Turning off wifi except when I am using it has made a significant difference for me as well.

Putting the CPU at 80 or 90% CPU speed in the performance settings will get you that reduced power consumption. You might not even notice the speed difference. These speed tiers also run at lower voltage.
Using the GPU frame rate limiter will dramatically extend gaming time too. I find 30 fps acceptable most of the time.
Of course it would be nice to run the thing unrestricted, but it's just not practical when you also want battery life. Look at what Nintendo is doing with the clock speeds of the X1 in the Switch.
