Been running Android for over a week now and this morning when pulling the phone of the charger I noticed it was only at 89%. This is from a full overnight charge.
Got to work and it had dropped to 85% (Watching videos) and plugged it into my laptop at work and it again only charged to 89%
Anyone else had the same issue. Will cut back to Windows to see if it goes further.

Hello dude!
Try removing the battery, wait a few minutes and put it again. See what happen.
Sometimes it is a error when the driver is "reading" the battery settings/status.
Hope it help!!
Same with me, only 90% with all night chage
Same here mine will only charge to 93% while charging overnight
Rebooting into womo and it then proceeded to charge to 100%.
Not a major but a bug that needs investigating.
also had this issue a user responded to me on the builds thread, he said to let it run down to 5% and plug the charger back in. also the one about booting to wm then back on android should fix it.
Same here at 94%. Seems to be a common problem...

Yes, I've got a same problem.
I've heard that no Charging-Stop exists (in kernel), so you may "destroy" your battery because it is overcharging ... so be careful
mine stops at 93%
yeah im a bit scared for my battery...ive been charging it almost twice a day now cause it dies so fast
i even have SetCPU with the profiles from the other thread, but its still draining REALLY fast...
i hope this doesnt have any permanent damage to the battery :S

where did you hear that? can you confirm?
The no stop sounds like complete nonsense. For one, it would be an obvious massive problem so the devs would have worked on it. Two, if you can detect battery charge it would be really easy to make it stop. Three, if it didn't stop, why did it used to halt at 98% for most people?

also battery working in read only mode, it's why during long android usage u can get wrong results. Will be fixed in future.
Hard reset..is only one solution
Actually _everyone_ can get this problem - after reboot u won't able to launch any external exe (exe from rom will work).
It happen because something sometimes can be corrupted during WM shutdown...
I got this problem two times Both time need to hard reset device.
So I recommend to everyone make backups!
So is it confirmed that robot voice (apt voice ) issue fixed now?
^^
confirm problem
read this before post
I have the same problem. HTC wildfire.
Try recalibrating the battery:
1. Turn off all uncessesary apps in the background.
2. Let the battery of the phone run out until it turns its self off.
3. Take out the battery for 2 minutes
4. Put the battery back in and charge the battery until it is fully charged "At least 4 hours"
5. Once it has charged take the battery out for 2 minutes then put it back in and boot the phone up
I managed
The phone was on and charging all night and it was at 97%. I turned off the phone and left it plugged for couple of hours, on and its 100%. Simples
"Show low low battery logo" Nexus 7 thinks battery is dead even when fully charged!
I have already got a replacement on order from the Play Store but since I haven't seen any reports on this after plenty of searching I figured I'd describe the issue.
My 16gb Nexus 7 worked pretty much flawlessly for the first several days of pretty light use minus very minimal flicker on occasion. As of two days ago the unit is basically unusable as it randomly but excessively decides that the battery is dead even though it is fully charged. The first several times this happened I wasn't paying attention and I thought it just shut off by itself, but then I started to watch it more closely but it also started happening more and more. As of this morning it will not stay on more than 5 minutes before it audibly notifies a low battery with the messages "Connect Charger" and "Powering down". Sometimes it will give two options "Battery" and "OK" but I was never able to actually get the buttons to respond because it would already be shutting down. Other times it will just show the connect charger and powering down messages with no buttons which is strange, but in either case the device shuts down.
Once I started troubleshooting I figured out a little more information.
Watching the lock screen while it is charging I will see it go from it's (I think) correct charge percent to 0% randomly.
While not charging it will either show a red battery indicator in the notification area or just an empty battery when it decides to shut down
Sometimes it will boot right up and be back up to regular charge level (of course just to shut down again within a few minutes)
Other times it will not boot up and I noticed the error message (almost like a debug prompt mistakenly left in the code) in the upper left corner "Show low low battery logo" + some strange symbol like when you get 100 1-Ups in Super Mario Brothers . Yes the message has the word "low" twice - I guess this is lower than standard low!
Anyway, kinda bummed but since I have not seen any other report of this particular issue I'm hopeful that the replacement will not have the same problem. I'm just hoping I don't get a unit that has some of the other problems being reported so I'm crossing my fingers.
Mine started doing the same this morning

This sounds pretty similar to my problem from another thread. Every time it hits 25% while discharging it dies. Normally I'd say it's just a software calibration issue and fixable by wiping battery stats, but I've wiped several times at 100% and run down to 25% and it still dies.
Do you find that you still get a normal amount of battery life before it dies? It'd help to establish whether this is the battery misreporting, or actually not discharging properly.
* Strangely this time after my N7 had died at 25% I turned it on and it's at 0% battery. It's been charging for ~15min and it still says 0%... When you all first got the device, did you let it run to 0%, or did you charge it right away?
** And now, after almost an hour, it's at 1%. Seems to be charging, but brutally slowly (and I'm using the bundled charger, not PC USB).

Yours sounds like a similar but different issue. My N7 dies regardless of how much charge it has. It can have 100% charge and within 5 minutes it will report 0% charge and die. Then when I can get it to boot again it will be back up to 99% charge again. I can't get more than 10 minutes of use before it dies regardless of how much charge it truly has.

I'm starting to have this same issue, however mine goes at about 19%. Just turns off. I have also seen the show low battery in white text thing. I have tried calibrating by fully charging then deleting batterystats.bin from data/system and letting it decharge and it still died around there, I'm recharging again to 100 to see what happens this next time I let it go... thought mine was issue free than this happens
Well in case anyone else runs into this, I have no idea what caused this or how I got out of it thinking it was dead at 20%. I tried deleting the stats, reflashed stock and then CM10 and back again, tried a different kernel, and still died at 20 and gave me the "low low battery logo".
I just took it into Gamestop where I got it and started the process for an exchange, so I have another one coming now. Go figure when I got home I plugged it back in, and now this time just like omnikai said instead of being at 20% it was at 0 when I turned it on. Been a while and now and seems to be charging normally so hopefully it will decharge fine.. either way really weird only problem I've had with mine so far
** Just wanted to edit and say its now decharging normally dont know what caused it to spazz out or fix it one of those ghost in the machine android moments

Replacement N7 seems to be fine thusfar...
Apparently, somebody in StackExchange is having the same issue as well:
http://android.stackexchange.com/questions/27222/nexus-7-system-error-show-low-battery-logo
if anyone else gets this, try disconnecting the battery and then re connect and see if that fixes it. i had same type of issue on viewsonic g-tab and that was the required fix.
Mine did it at 10%, calibrated the battery and im getting truly awesome battery life 2 full days without a charge

While this reply is late to the game, it needs to be pointed out that such apps are 100% snake oil and do not calibrate the battery. They are based upon gross misinformation and any dev that tells you that clearing batterystats.bin has any effect on battery life or reported battery charge clearly doesn't know how Android works.

Have you fixed this yet cos mine does the same?
I had been having the same problems that everyone described: would suddenly die at 25% and wouldn't turn back on unless I gave it a charge for a bit and then held the power button down for a while.
For the last 2 weeks, I've been charging it only with the stock charger and that seems to have fixed it. Previously I would charge with any charger I had around.
Not sure if it's a permanent fix but it's working now (I've taken it down to 4% before charging it back up).

I only use the stock charger on mine but after this happened so often I tried another one and battery charged OK but then kept blipping from say 50% to 54%, went bed with it at 49% and this morning dead again. Charged it again today on stock charger and waiting to see what happens.
Sorry all for this bump.
I just got this same issue tonight on stock, unrooted nexus 7 16gb and I only use the stock charger, I let it die through battery and then when I charged it amend turned it on, all these problems happened.
One symptom that hasn't been mentioned is that the clock is set back to January 1st 1am.
I managed to get it to start without turning off by holding the power button until the Google logo showed twice, at the moment it's on but charging.
Hope this doesn't become a problem again in the future.

I recently started having the same problem with my 2 month old rooted Nexus 7 (wifi only) . It was dying at about 19% - 23% charge . Tried doing the battery recallibration at 100% charge, even wiped the device clean and flashed the Jellybean 4.2 factory image but it didn't work.
I talked with the ASUS service center guys to get it fixed, and created a sort of guest user so that I won't have to disconnect my accounts. After that my problem seems to have been fixed. I discharged it to about 4% and then put it to charge, it's charging properly now so I am hoping the problem has been fixed.
I am not sure whether this would work for everybody, but I guess it's worth a try.
I have this strange issue with the battery calibration.
At first i thought the battery was dying on me. It normally stay active to 35-44% and then the OS would just suddenly report the battery is dead and just turns off.
Then i just boot into TWRP recovery and leave the screen on. And it's able to stay on for another whole hour at maximum screen brightness till it actually dies.
I tried deleting the battery stats in the data folder and letting it drain to 0%. But the OS still thinks it's out of juice around 35-44%...despite the fact that it can stay on for another hour or so in TWRP recovery.
Is there anyway to adjust the capacity of the battery in the OS?
Hi,
When this happened to me (but with 20%), all I did was letting the battery drain and charge it fully while turned off. Don't know if it actually works, but it solved my issue. Give it a try .
Good luck,

Funny, I had just about the opposite problem. It was stuck at 35-45% while charging, or it would only go up about 1% every 20-30 minutes. Sloooowwww. Same solution seemed to fix it--let it drain to shut-down, recharge with power off to 100%. It seems to charge faster with power off, but I haven't done an a-b test to verify.
So I just started getting this after the update to 5.0 on my N10.
Beforehand I never noticed anything, although its been a few months since i have used it till a really low battery.
But I updated to 5.0. Used it for a while, the OS registered like 70% battery and then instantly 0% and it shut down. So I booted to the bootloader to see and it ran just fine for a while. I got bored and booted it back up, immediately shut down.
I plugged it in and booted it up and it was a 0% for a LONG time before it ever registered as actually charging. Then it charged normally until it got to like 25% and then instantly to 100%.
Im hoping its just a calibration thing, I did a factory reset just to be safe but it still did it. I guess the next steps if it still does it after a few cycles is to install a custom recovery and clear stats.
Same thing here
I've got almost the identical issue as the OP. Tablet shuts off without warning around 35-40% batter. When I reboot it says 0% battery and immediatley shuts down. If I boot into recovery mode though it will stay on for 2-3 hours before dying. I tried this and then charged it to full overnight with the device powered down and still today it shutdown again around 40% battery. Tried a battery calibration app before too but nothing has fixed it. This is 4.4.4 stock rooted with xposed. Been happening for about 2-3 weeks now. I'm pretty sure it's got to be software related right?? Anyone find a fix yet?
Just posting to say I'm seeing the exact same thing. It also just started happening since the update to Lollipop. It is shutting down at about 30-40%, then when I turn it back on it is at 0% and will shut down immediately unless it's plugged in. However, like the rest of you also said, in safe mode it'll stay on for a while longer without being plugged in. We really need a way to calibrate the battery somehow. This is a very frustrating problem. No warning at all!
I also have this problem.....this updates are so bugged.....

I have the exact same issue
After a full charge it's saying I only have three hours left on the battery. Battery life is really poor. I'm not sure if the battery is worn out (I've had the tablet since it came out) or if it's from the update.
Same same.
Just had the same start yesterday. Was charged to 100% ran a high intenssity game for an hour (makes my cell phone heat up and kills the battery like mad) but it was NOT affecting the 100% charge. I thought 'thats funny' then it started to go down some then it hit about 55% then BAM. Drops to zero and shuts off.
After that it would not take a charge no matter what I did but then for no particular reason except I was lazy and didnt wanna have to boot it up again after I plugged it in, I left it plugged in and went to take a nap. Came back an hour later and it had charged to 43% after having been at zero for about 20 minutes after I left the room.
Now its stuck at 43% and wont charge any higher. I'm leaving it alone for a few hours to see if it will ever get to 100% then ill run it down to zero then charge it over night turned off to 100%.
Ive been reading this as a battery calibration problem and came across a HUGE variance on the net about what to do about 'that'.
Some say the charge to 100% drop to 0% charge to 100% will calibrate it. Some say thats old Ni-Cad tech and you shouldnt do that with the Lithium Ions. But then others say you should do it with the Nexus 10 because it DOES calibrate the battery and that the tablet software protects the battery from actually going to zero%. (Saves a few percent and shuts off).
But then also someone else said battery calibration only works via a hardware change inside the tablet and that we are actually talking about conditioning. But then someone said conditioning is the max storage and that the 40% to 0% drop is not conditioning and since the charge discharge charge is for conditioning a Ni-Cad it wont help. Around we go.
There was also mention of a samsung PHONE having a problem with a bent usb pin inside the phone. But you had to pop the battery to bend the pin and since you cant do that a on Nexus 10 that doesnt help. (Plus the pin doesnt look bent to me even though about 30 people chimed in saying it helped them. But that was all phones.)
And finally. One website says you have to root the nexus 10 and use a batter calibratino app to calibrate it as option a but option b was some crazy combination of charge to 100 discharge for an hour, charge to 100, discharge for an hour, charge to 100, discharge till your aunts pink underwear falls off or something equally strange.
I'm betting based on you guys os upgrade bug. Just too strange. My 2 year warrenty ran out last month but I hadnt turned it on in six. Maybe thats a good thing. Be stupid to send it in for repair only to find out it was software.
Have to see if after my full cycle charge-discharge-charge it works again.
Prayin for everyone's devices. This sucks.

Suffice it to say I've been seeing this issue as of Android 4.4.4... NONE of the posted recalibration techniques seem to work and as usual, Google non-support is just as useless. As far as I can tell, once in this state it's here to stay... I've had my N10 shut down at 28%, 37%... even as high as 55%, and on re-charge (if I do it turned on) it charges to a point and then shoots straight up to 100%. I've seen the "takes forever to get above 0%" issue too... none of this has happened in any consistent fashion. I had hoped that friggin lollipop would solve this but instead they added a host of OTHER annoying bugs: as in after I restart it, the tablet goes into an optimization mode where it decides it has to re-optimize all 362 apps I have on the wretched thing. There naturally are a few others but they are beyond the mainstream of this evening's symposium....
Same exact thing is happening to me, but I'm on 4.4.
Same issue for me toosince 5.0 (now 5.1.1 BlissPop)
I'm gonna try to see if after my full cycle charge/discharge/charge it will work again...
Same issue for me too, since 5.0
Same issue for me too, since 5.0
to all of you how had had battery charging problems, please advise y you have used the "magenetic" charging cable. (It charge to a 25% higer rate)
I don't know how... I don't know why... After nearly 10 months of this behavior... I recently went through a couple of charge cycles (after it dropped to zero yet again) without letting it drop to zero.. AND NOW IT'S FINE!!!! I have no clue why... None of the stupid on-line non root solutions worked... I think that it's possible for this thing to recover after a random sequence of events which unfortunately cannot quantify because I had pretty much given up.

I am getting the same experience as most of you. Tablet shuts off at around 45% saying there's zero battery left. I assumed it was the battery going bad.
Sent from my Nexus 10 using Tapatalk
Well technically the battery starts going bad (yeah it's not supposed to... but nothing lasts forever) once you start running the discharge/charge cyle over and over again. To be sure my N10 is more than a few years old and while depending on use it can last a few days... it sure doesn't go quite as long as it did between charges as when it was brand-spanking-new. That said, and as said in my more recent post where I thought that the battery was borked, it now will last around two days with heavy use and about three with moderate use... and it now discharges appropriately to near zero warning me to connect the charger without just dying at 30-50 %... and the charge profile is a smooth curve from low to high with no sudden jog to 100% once the charge indication hits 60-65% like it did before. That would *seem* to indicate to me that this is far more a software issue than a battery one, and that purchasing a new battery may "fix" the problem but it won't FIX the problem! i.e. it'll only be a matter of time before it comes back. For all I know, some recent update to some google app took care of it...
After updating from CM11 to stock 5.1.1 I got the same problem. My N10 switch emmidiatly off at 70% battery. It was fine with CM11. Any news on this? Did a battery calibration, but this didn't helped.
I'm also getting this problem for the first time on the Temasek CM rom from 11/05/2015. It seems to have come up only since the 11/05 version.
Still no solution!?
I am having this issue (I think) since I received the update to Lollipop. So, basically it is a bit more than a year now. I was hoping a Marshmallow update would solve it, but: nope!
For installing Marshmallow I also did factory reset and all that stuff: it does not fix the problem...
Each time I reboot my OPT, the battery level drops by at least 4-5%. I also find the phone takes pretty long to boot in general (around half a minute, if not more). With my Huawei Mate 7, rebooting was a matter of seconds, and the battery hardly lost 1% in the process. (The phone had other issues, though ...)
Who is experiencing the same? What could be the issue? Purely apps autostarting, or could it be something else? Note that I am rooted, running Xposed (with only 2 modules: GravityBox and VibrateMode) and on Boeffla Kernel beta15. I don't use Greenify and Amplify (anymore) and don't perform any heavy tasks on startup, except for loading some widgets (Google News & Weather, Google Calendar and Google Keep).
Same
Happens to me as well, using the same kernel, though i use kernel Auditor app too which starts on reboot, have greenify aswell .. battery drains by 4-5% on a reboot
Wow ... this is really such bulls**t ...
I adjusted multiple settings today that each needed a reboot. First I was at 30% battery, after the reboot I was suddenly at 20%. Note that before that, the indicated battery percentage had stayed at 30% for about two hours, despite being on mobile data with apps running in the background (not normal!) Then, I made a nother reboot. Immediately after that, the battery was at 17%, then suddenly dropped to 15% after several minutes, and several minutes later again to 11%.
Clearly this is a bug in how OOS calculates the battery percentage and something OnePlus needs to address in (one of) the next system update(s).
EDIT: LOL ... while I wrote this, my battery dropped to 7% ...
i can second this..., so if you dont want your battery to drop, dont reboot! LoL, kind pain in the *ss

Yeah, but you sometimes have to, like when updating an Xposed module or changing a setting that requries a reboot ... though I admit, none of this happens on a daily basis.
I tried soft reboots, but those seem to lead to issues with the phone recognizing the network carrier correctly ...
Hello, OnePlus, are you going to fix all of these annoying bugs in the next OOS update?
Today: percentage stuck at 44%, down to 41% after reboot, drop to 33% after several minutes. This is the most extreme case I have experienced yet ...

That's exactly why i only updating xposed modules, adaway host etc at night before sleeping with the phone plugged to wall charger, LoL
Like those?
First time that happens to me.

Whoa! I never had it THAT extreme ... I wonder what is wrong with the way the battery percentage is calculated. Seems like something with the calibration is way off in OOS.
Another observation: This doesn't seem to happen when the battery is freshly charged. I just did 2 reboots after charging to 100%, the first time it dropped to 99%, the second time to 97%. -> more evidence that the percentage isn't properly calculated while the phone is in use, hence these heavy drops from time to time vs. percentage staying the same for multiple hours.
Yep I'm seeing this too, mine even appeared to jump up after a reboot a couple of times
I am having the same issues, easily leading to 5-10% less battery after rebooting!
Also, my battery goes through the first 15 % or so very easily and then settles, there is clearly something wrong with the calibration!
There is clearly something very wrong with the battery calibration and/or the way OOS calculates the remaining battery percentage/time. I charged my phone to 100% percent over night, played a power-hungry 3D game on the train for 30 minutes, then flashed the latest Boeffla Kernel and did two reboots. I was at 78% after playing and at 64% after the second reboot (which seems "normal"), now my phone is idling at 64% since 2 hours.
Notice that the remaining time is shown as less than 2 hrs, and has been like that for 2 hrs ... this is highly unlikely. Also, what's the big gap there? The reboots surely didn't take half an hour ...
I also experienced this battery percentage stuck thing it stuck at 24%for few hours during that period my cellular data is on and sot is also half an hour during that time.
After that battery percentage suddenly drops to 20%.
Was experiencing the same, I tried calibrating my battery (Let it die, then charge it while it's off to 100%, run a battery calibration app, restart, charge it again to 100%), I used a 5V/1.8A LG adaptor (and not the original one, which seems to mess up touch sensitivity) and it seems to be fixed by now.
[TL;DR]
Phone battery suddenly drains faster than usual, drains to 0% overnight. Problem still persist even after April update and after battery change. Can't find any solutions. Help me.
Hey, so about a week ago something very strange happened to my Mi A1 and got worse overtime. So what happened was my battery went from 80+% to 0% overnight. I woke up confused and just recharged it and didn't think too much. After a full charge, I noticed the battery drains abit more than usual and had to plug it in constantly. Before going to bed I charged my phone to 100% to see if it would drain to 0% again. It did. As time passes the problem gets worst. The phone started getting warm when charging (around 40+°C up to 50°C) then after a while the phone runs warm even when not charging (never goes below 40°C). My phone always used to run at about 30-35°C even when charging. I changed the battery myself because there was no warranty on it but it didn't fix the problem. However it did help abit. The battery drains ever so slightly slower now but still drains to 0% overnight. It still runs warm but now it does go below 40°C (rarely). Before and after the battery change, the discharging rate is about 700mA and sometimes reaches 1000+mA (used an app called Ampere, not too sure how accurate it is). The phone was also warmer than usual when charging even when the phone was off (before and after the battery change). I tried factory resetting to see if that does anything but had no luck. I also tried using a Wakelock detector app to see if there was an app excessively triggering a wakelock but all seemed normal. I even tried downloading a "battery calibration app" which obviously didn't work. So I feel like it's a hardware problem.
Now here's what I did and did not do to the phone before the problem happened. What I did was I do charge the phone quite alot most of the time. What I mean by that is when it hits about 30% I'll plug it in but I never leave it plugged in after a full charge or charge it overnight and I seldom let the battery drain to below 10%. Even so, the phone never got warm like how it is now. That's about all I did to it. Now what I didn't do was, I never tried to install custom ROMs or root/modify my phone in anyway except for the post about how to enable 4G+ which didn't work for me.. My phone is completely stock. I also didn't install any new apps from the playstore or from any 3rd party sites nor were there any updates for any apps installed in my phone. I've had the same apps installed for a couple of months before this happened. I also haven't dropped my phone for a couple of months. I only dropped it less than 5 times from short heights and I have a very rugged case on. I also didn't use any 3rd party chargers. I'm still using the charging brick and cable that came with the phone. I have tried using other chargers that are 2A but no luck. So basically I didn't do anything out of the ordinary prior to this problem.
Just some extra information
1. The hottest part of the phone is at the top right corner of the back. I assume the CPU is there (?).
2. It happened before the April update. It was the same before and after the April update.
3. Phone is running on Android Pie if that wasn't clear
4. The phone is only 10 months old
5. My phone is the Global ROM version
6. Performance wise, its still responsive and snappy. Doesn't lag or freeze or anything.
6. I always have mobile data on and use it as hotspot for my laptop at uni. I have been using it like that for the past 9 months. However the problem happened when I was at home during sem break so I was mostly connected to Wi-Fi.
Sorry for such a long post. I hope somewhere out there, there is someone who can help me or other people that have a similar problem so we can fix it.
Thanks.
In the upper right corner, should be the modem area.
Try holding the phone on airplane mode during the night and monitor drain.
Also, try changing the SIM slot and do an APN reset. If this fails too, try changing your SIM card or if u can, try another operator SIM.
If you changed any value with QXDM PRO , try and put back the default values.
Good luck
