the meter only gets upto around 30% no matter how long i charge it for, when i reset it goes to around 60% but never 100%. anyone know whats going on here!?
hopefully, you have another app that is causing a false reading, if not check the time you get and clean the terminals on batt and pda
it was doing this without anything installed, will try a hard reset and check again.
how long it take to do a full charge?
did a hard reset been charginh for 1.5 hours no progress bar just goes up and down. unplugged said 18% did soft reset says 56% back on charge looks like its going to take 3 hours for a full charge!
is some going to tell me how long it takes to do a full charge!?

All,
Please try this before complaining about battery.
Go to:
Settings then to privacy then do a Factory Data Reset.

What ive noticed on day 1 Battery showed full charge. After a factory data reset the battery meter dropped to almost empty
full charge overnight and i went all day and night after using pandora, making 3 hours worth of calls, using the web, check checking work and gmail email, sending texts and a few other thing.
With my evo i would have had to charge it after about 6 hours. PLease try the above and post your results.
Nice find dude. I just tried it out on my phone and while it may be a bit preliminary it seems to of fixed my issues. Before I had only been able to charge my phone to 100% TWICE. All the other times it would hit 95-97% and tell me its fully charged and would not go any further, i would turn off my phone and plug it back in and it would charge a little more, but as soon as i unplugged my phone and booted back up it would be at 95% and fall very quickly. This morning it had only been unplugged for 1 hour and 20 minutes after being plugged in all night and it went down to 65% I plugged it back in and let it charge, it was at 95% and still charging when i saw your post and decided WTH and gave it a try.
While it was still plugged in i did a factory reset and it erased everything and when it booted back up it said my phone was at 100% but the charging light was still red. I let it keep charging, even turned it off and it was still charging, it charged for probably another half hour before the light turned blue, i unplugged it and turned it on and it was still at 100% I used my phone sending texts and reinstalling all my apps and setting them up and its been probably half an hour and its at 98% as i type this So things are looking up I never even saw 98% before haha, the two times it DID charge to 100% it literally jumped from 96% straight to 100%, then fell to 95% once unplugged.
Just out of curiosity what do you guys use to check your battery percentages? (i'm new to android having come from the iphone 3g)
I've been using Battery Indicator, I really like it.
h**p://www.androlib.com/android.application.com-darshancomputing-batteryindicator-xxti.aspx
Also, from what I've been reading so far, most of the issues are app related and a few defective batteries.
Tried this and didn't seem to work, the display is still hogging 70%+
RE: Battery Stat Wipe
I did a factory restore today bc my phone was acting all crazy. Do I need to do a battery stat wipe? I'm not sure, but I think it has been going down quicker than usual today for some reason. Thank you in advance for your input.
I also want to know how. My batt went crazy since yesterday
looks like everytime the phone is hooked up to the sync cable, the system interprets it as hooking up to the power supply because it's low-batt.. so the calibration calculates the last time you unplugged from the power supply to the time you synchronize your phone thus gives you the expected uptime duration of the remaining charge from there.. correct me if im wrong.. but my duration now is shortened to 6hours (expected) on one full charge.
can somebody confirm if the uptime is governed by the batterystats.bin/software issue and not the actual power left on the battery? your phone will die eventhough you still have an actual 40% of charge if the software says so?
btw, to address your issues Gseeker and acPIZZA, at 5% charge left, go to data>system and delete batterystats.bin.. then use your phone all the way til it dies. from off state, charge it all the way up to 100% (stay connected to the charger for another 2 hours even it already displays 100% because it is not actually 100%). then power up your phone, you can notice the difference.. i did it like that and my phone lasts for more than a day at average use.
So I noticed something weird about my phone. When you go to menu>settings>about phone>battery usage, it tells you when you last unplugged well my phone does not seem to reset that timer always . I can plug it in for a couple hours and take it off charge (battery level does increase) and it will still say i have been unplugged for X amount of hours. Anyone have this issue. Never happened in any of my previous android phones. Btw stock Nexus S 4g, Im truly stumped on this and looks like no one else has this issue.
I think it only resets once the battery becomes fully charged.
Thats what it seems like its doing but i know my previous android devices would restart the timer when i would plug in even for a second or when i turn off my phone and turn it back on granted my last phone was a Epic on 2.2 so i don't know if that makes a difference. This one only seems to do it at a full charge like you said hmm interesting. Other people having the same results?
I've seen it before. I once had it going to five days. I tried restarting the phone, but didn't work. Had to clear battery stats in recovery but like you said you're stock.
yes, since gingerbread, battery stats reset only if you keep charging until 90% or more. I have a nexus one and with 2.2 it reset every time, but not anymore.
Okay good to know its just a gingerbread 90% thing because i thought something was messed up. thanks!
Did you used the USB-charger? Then it won't reset the timer.

Yes I am using the Stock charger in my PC or plugged into the wall plug it wont reset it until it hits a high battery charge level.
Soo i fully charged to 95% last night and when i took it off this morning the timer still didn't reset hmmm at this point im tempted to go around root and clear my battery stats
No one has mentioned the battery usage graph (hard to notice, but there behind the "Time since last charge" message on the top) which shows battery usage over time since last full charge, including interim partial charges as hills...

I am now getting this problem too where it doesn't reset, even after it charges overnight and hits a high charge amount (94+%). Did you ever figure out a way to get it to reset to 0 sec on battery without resetting battery stats?
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...
Yesterday, my battery was running perfectly fine. Today, the battery goes for about 10 minutes on screen time. Getting it charged from 10% to 100% is very quick, maybe takes about 10 minutes. But going from 100%, it can discharge at about 5% per minute, regardless if im using it or not. When I was at 70%, i tried to restart my phone to see if it would fix it, but when It was going to turn back on, i was greeted with the low battery sign, signaling that the phone wasn't able to turn on. 70% = No Battery? Battery drains by 2% per minute when screen is off.
I'm running Lineage OS 14.1 official rom with magisk. Please help.
GSam Battery Monitor Says that 60% of battery is consumed by "Kernel (Android OS)"
Many times i have watched my battery go down multiple percent in a matter of a second its really scary

Your phone needs to re calibrate the battery. This is probably the bit I like the least about these phones. Near as I can tell the best method is to let it drain till dead - then plug in with your charger and leave for several hours. Power on while phone is still plugged in - let it continue charging another hour.
Use normally. You may need to repeat this a few times.

I've done that about 4 times. It didn't really make a difference... then I used a battery callibration app from the play store which didn't even require a full battery drain or charge and it worked very well... weird.
