Anybody had this problem?
I've had my GS2 for nearly 3 months and all has been well. Coming from a Motorola XT720, EVERYTHING is better including the battery life.
Last week I noticed that when connecting the charger, it took a long time for the phone to register that it was connected, ie. it didn't beep, light up and show the charging icon. It was also slow to recognize that the charger had been disconnected. (The charging icon would stay on for some time after.)
I thought a re-boot would help and it threw up the big battery charging icon flashing alternately with the battery over heating icon! Even pulling the battery wouldn't stop the warning message unless it was removed for at least a couple of hours or re-booting via Home, Vol+ and Power.
Whilst all of this was happening, battery life plummeted. I normally get about 1-3% loss of battery per hour in standby but this increased to 5-10% per hour.
The phone has somehow regained its normal response to the charger being connected and disconnected but the poor battery life remains.
Its un-locked, un-rooted and running KF3:KE7:KD1
Any ideas before I do a complete reset?
I would get a new battery to start with, if you UK, 7dayshop.com have an 1800mah for only. £4.49 delivered.

Thanks. I forgot to mention that I've just bought an Andida "2000"mAh battery from Mobilefun. It's only had a couple charging cycles but it's behaving exactly the same as the original battery, which confuses things!
It could be that the problem is effecting it our it's just not working at it's full potential yet.

Even the biggest best know battery manufactures cannot make a 2000mah battery to fit the S2 without needing a replacement back cover, the new Samsung 2000mah needs one.
So the Andida "2000"mAh battery , is more likely to be around 1500-1800mah
Yep, if something sounds too good to be true, it probably is! Will probably return it and wait for the
official Samsung 2000 mAh.
Would still like to know what's going on with the sudden loss of battery life.

Since you have tried a second battery and the phone is acting the same way the fault must be with the phone, the charging socket is not loose or something?
Or maybe the phone charger is faulty, do you have a second to try?
It looks like you should try a reset before you seek refund/replacement.
Since Sunday my Aria has started heating up weirdly. When charging and while using, there is tremendous heating in the area right behind the optical touchpad.
Also the battery is not charging properly and discharging quickly.
I first thought it may be a battery problem, but wanted some genuine views regarding this.
Will changing my battery remove this issue? Has anyone faced anything similar?
There will always be heat around the touchpad whenever you are charging while using it. Happens to me all the time at least. Unless your battery exceeded 45 degrees Celsius, then that's abnormal.
You can track your battery stats for example, heat with apps in Market.
You said it discharges awfully quickly. Mind telling me, how long does it take for it to discharge from 100% to below 10%?
Really quickly.
For example, I charged the phone whole night from a wall charger, while switched off.
In the morning, I turn on the phone, it shows me 19% battery. I rebooted: 8%. Rebooted again: 2%. This all happened in about 5 minutes after taking the phone off the charger.
The phone used the 2% battery for about 15 minutes on standby, with no internet, before dying.
Now it does not even turn on. The battery is definitely gone, since it has bulged a bit. But I want to be sure before buying a new battery, if the new battery will face the same fate or not.
For now, I have given the phone to my brother who will test the battery in his phone. Let's see.
There's definitely a problem with the battery. It is advised you do not charge a faulty battery. It may damage your device or worse, explode depending on what the fault may be.

New battery should fix the problem. There's no reason to suspect that the phone is causing the problem.
[Q] Crash&battery drop then recharge w/o plugging in on rooted i9100 Jellybean 4.1.2
I've been getting an issue with my almost-new i9100. By Googling, I've found a few other people who've been getting the same issue but most haven't noticed something important that is probably pretty important to fixing the problem. So far I've not solved the issue.
I'm running stock Jellybean 4.1.2 updated over Kies. My phone is rooted.
If, say, I charge my phone overnight, so I have a full (or nearly full) battery, at some point (usually when the battery has got down to about 50%) the phone will die. If the screen happens to be on when it dies then you'll see a screen flicker before it dies.
When you manage to get the phone back on (usually by plugging it in, waiting for it to start to charge, then turning it on, the battery reads 0%! If, however, you allow the percentage to climb a bit then unplug the phone, the percentage continues to climb.
Once the reported battery level has stabilised, the graph of battery charge level over time looks like the normal steady gradient down, but with a huge chunk out of it, showing that the battery dropped from about 50% to 0 instantly and then climbed to its true level gradually.
(I'll try to get a screengrab of the graph next time)
There's also a gap in the graph that I think indicates an OS crash?
Does anyone have any idea what might be causing this? A factory reset didn't fix it.
At first I thought it was a battery calibration error, but I've run the phone to fully dead to fully charged a couple of times now and deleted batterystats.bin (even though reliable sources say that this does jack ****). Beginning to think it's a kernel crash.
All the symptoms of a faulty battery.

Are those symptoms definitely confirmed to be symptoms of a faulty battery? I can't find it now, but in another forum post I found describing very similar symptoms, the guy swapped his battery to no avail.
Had the same symptoms for a faulty battery.Reflash stock ROM through Odin and see.

Okay I just had this issue on my N10, but I solved it by switching the charger out (yes sounds stupid, but it helped)
I did have this problem on other tablets however and I am happy to share the solutions I have found over the years.
Solution 1: Battery stats.
Plug it in and boot into twrp. If it just keeps showing a faint white battery icon, use solution 2. Now max out the screen brightness, and let it die. Now plug it in and charge it to 100%, boot into the OS and calibrate the battery by wiping the battery stats or grabbing a battery calibration app off the play store.
Solution 2: Different charger/Wall Brick
This was my N10s issue, I tried solution 1 but that didn't help, so I tried switching out the wall brick. I traded my 5 Watt amazon adapter for a generic usb wall brick. My wall brick heats up, yours might not. You know that the charger is a problem when you plug it in and the battery icon is dim, it should be full brightness and doing a little charging animation. I noticed that this generic brick would do the animation so I tried just leaving it plugged into that, and my tablet is now at 7% and going up slowly.
Solution 3: Reboot over and over again
Exactly the title. On my old kindle, the battery would occasionally come up with a real number rather than 0%.
Solution 4: Rom cycling
Flashing a different rom. I had to do this on my old tablet a few times, but it would fix it sometimes. Honestly any rom will do, just keep cycling.
Solution 5: Replace the battery
Lastly you could just replace the battery. a battery is about 40$ on amazon, so this is a bit pricey. This is a last resort and will most likely fix your problem, and if it doesn't, you'll at least have a nice full battery for when you do. I've never done this, but I've read about people having success when they do.
Tried most of the items you pointed out and unfortunately changing the battery was my only success.
However the new battery is also starting to give away. Using it as a photo frame so battery is not a issue, the yellowing of the screen however is..

'ole N10 user here, ordered a $23 replacement battery just now then hoping it resolves basically a dead battery. I own lots of tablets but a "why not" feeling if $23 makes it as-new.

I can confirm that there is something strange going on on the nexus 10 hardware. When I received my second hand nexus 10 ,it shoots down at 40% . Now after 3 months, I don't know why but trying to charge in twrp, let it go drain all the battery in twrp, and charging when it's turned off completely recovered the charging hardware ,because I know the battery can't recover from a bad state . Now it turns off at 0% , and it's not only a calibration effect, it lasts longer than before. I charged mine with an aukey charger and some good quality cables . I never used the original wall charger , because the aukey has 5 connectors and I use it to charge all my devices

I fixed it, turns out it was the charger I was using. Guess I was lucky, my Nexus 10 is a champ now.
I fitted my Nexus 10 battery. Bought the battery [URL="https://www.youtube.com/watch?v=yru4k62qdEU"]here[/URL] and used this video guide. It was very easy took me about 30m watching and re-watching the key steps, the ribbons being the one to pay particular attention. Wow, though 17 screws......
I have Android N via Pure Nexus unofficial build and its performing well. Its relatively slow cpu by today's standards does make it stutter more if I make it do a few things at once, relative to my Pixel C, but I love the forward speakers and good now for a spare tablet. I just did similar thing for my Nexus 7 2013.
The Pogo pins is finnicky takes a few connection attempts til it works. I can see why 2 models later (after Nexus 10 was 9 then Pixel C) they moved to USB-C 3A 5V 15W its far quicker.
I've replaced the battery, changed a few roms, use different chargers all the time (whichever is Handy), and tried resetting the battery stats. No joy so far. Always shuts down at 30%.

I had the same issue with a new battery. I charged it up to 100% then went into twrp (I'm running linage) and wiped the cache. Touch wood it seems fixed.
I'm having a good experience once I opened up my N10 and replaced the battery. I'm getting very good battery life, on full brightness about 8-9 hours.
I like the screen form factor for watching videos like MP4 or Netflix. It is so good I turned off my Pixel C at 60% charge to make its $600 expense I spent 18 months ago last as long as possible for when I need its performance which is when traveling.
The recharge performance is the biggest weakness, I have to plug in the Pogo cable and leave it alone. I have a bit of light bleed on bottom right corner. Audio via built in speaker is a bit feeble. Running Pure Nexus which eventually will get Oreo.
I bought my Nexus 10 when released. Battery still lasts till the end and charges fine to 100%.
But this screen is so bright, I always kept it at lowest brightness. No screen issues and no battery issues and use it everyday since new.
I bought my Nexus 10 the week it was released. The battery eventually stopped holding a charge, and I replaced it. Now my battery indicator is stuck at 100%, which is as bad as 0%.
I'm about to try a different ROM. Hopefully that will help.

Fully charge it, wipe battery stats, reboot
This is a common problem when swapping batteries on any device. It took me a while to respond because MeowDude is my old account.

I tried letting the battery drain until it shut down, then recharging to 100%. I think it's better - not sure.
How do I wipe the battery stats?

Last year my Nexus 10 was due for a new battery. I swapped it for a new genuine one, but since that day the Nexus will shut down at around 80% charge. It's not that this percentage is incorrect (it happens at around two hours of light use), but it somehow sees 80% as 'empty' and shuts down. I've tried all solutions mentioned in this thread but to no avail. Any ideas?

Since I replaced my battery, my Nexus 10 stays charged for days. If you've replaced the ROM (so you know it's not a software problem), then it must be a hardware problem. Hopefully you just got a bad battery, and it's not the Nexus 10 itself.
Phone is a ANS UL40 running 7.1.1
Battery will randomly go from partial charge to 0%.
This just started happening after having the phone about 6 months.
If I leave the phone unplugged overnight, it will be dead by morning (this is a new thing, it holds a charge pretty well). Doesn't have to be overnight either, could be just a half hour or something. The battery just dies randomly.
Even if I do have the phone plugged in and have the screen on (watching a youtube stream) it will randomly go to 0% and self shutdown.
Stock battery which seems to be stuck inside the phone. It doesn't seem to come out, I don't know if it's glued in or what.
ANS branded 3.8v 1700mAh 6.46Wh part # UL40BATT limited charge voltage: 4.35v
Printed: "Warning: This battery is built-in and is not removable"

Its actually removable -
I have the same issue with mine and I just received it as a replacement phone about 3 months ago. If anyone has a clue as to what to do please share. Been to all the blog pages and customer pages related to this model and it seems to be a recurring issue and so is overheating and a dozen other things. What the point in having Lifeline when all the phones that they give or sell don't work.
And I thought it was just me. Needing a lifeline phone seems to mean we get the worst of the worst devices. I had to pay extra for the UL40 because the "free" phone was useless. The UL40 is near useless, and this battery issue makes it unreliable.
i have the UL40 and requested a replacement phone (because of unsustainable malware issues that survived a factory reset) and the L50 they sent me had this issue. i couldn't find a solution and had to request another replacement.
oddly, i occasionally experienced an apparent battery discharge (phone powers off, needs to be connected to power to boot up again) but when it powered back on the battery was at ~65%, clearly plenty of power.
my completely uneducated guess is that the battery terminals in some of these phones are loose, either causing the battery to discharge completely or simply disconnect momentarily, resulting in the phone losing power.
