Battery keeps dying at around 30 - 40%. When I go to recharge, it starts at 0? - Nexus 4 Q&A, Help & Troubleshooting

Does anyone have any idea why this is happening? Started happening randomly about 2 weeks ago on stock 4.3. Switched to PA 3.99 then to CM, still happened. Flashed 4.4 and it died today at about 20%, usually it's around 40%.

Do you get a blinking red light sometimes when you charge it?
Try this for me. When your battery is at 30% try to take a picture with flash. If your phone shuts off then it might be that your battery is bad. From you have said I think the battery is bad. You will need to replace the battery.

you van try this:
1st: Set both max clock and min clock to 1.5ghz(1512 or something mhz).PS use trickster because sometimes setcpu dosent work or it get reverted.
2nd: use your phone normal, until it reaches 0% of battery(i dont mean 0%,what i mean is the state of it dosent even turning on because of low battery,a.k.a flashing red light).
3rd: hold down both volume rocker buttons for 60 seconds and then plug in the charger(if this is right it will simulate that you have removed the battery, you may wanna check if the combination is right, because my n4 is on rma :/)
4th: after that, recharge your phone for at least 6hours(remember: dont turn on the phone while recharging, let recharge with the phone off)
5th: after phone turned on, get back the min clock and max clock to its original value(usualy max 1512 or something and min 384 or something)
6th: profit(if it worked lol).

I've had similar issues after rebooting, particularly after doing something resource intensive like flashing or running a full backup. I think it's caused by a defect in the battery and plan on having Sprint replace my battery.

I had this issue twice already. I was not sure what the cause was. I believe it is a horrible battery bug.
I have this issue to. I went from 46 to 13. I also noticed that the battery meter in the staus bar seems off. While batt stat and gauge say i have 50% the meter looks if i have 80%
I was able to reproduce this bug fairly easily by rebooting while the phone is on the AC Charger while it's really low. I turned it back on and it went to like 50% when it really was at 10%. I unplugged it from the AC and then "Shutdown" not reboot. Turned it back on and it went back to 10%. Yeah just seems like a battery bug.
You dont actually lose that battery life, your phone just doesn't display it correctly. I bet you will be @ 3% for a loooooong time, also if you charge your phone, it will charge a lot faster than normal untill you reach 60% again.

"Show low low battery logo" Nexus 7 thinks battery is dead even when fully charged!

"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.

Incorrect reading for battery after updated to 4.2.2

Hi, today I went to office, I can see the battery reading is 84% after one hour of use in the transportation. When I plug the phone to the charger it shows 100% immediately (Charge so quickly isn't it ? :laugh. It remains 100% even I reboot the phone. Did anyone meet this bug?
Have never encounterd such a thing. Are you rooted?
Sv: Incorrect reading for battery after updated to 4.2.2
Never seem it but try a factory reset. I always do one after a system update.
Skickat från min Nexus 4
It's likely nothing is wrong. After every ROM flash, the battery calibration always messes up a bit. Just use the phone normally and the calibration will fix itself after a couple charge cycles. If you want to fix it sooner, run the battery down and charge it again.

That will happen with any/all N4's at some point. More commonly the battery will lie to you, forget to update battery level during deep sleep, etc... Your phone isn't "broken".
Mines just did that today.. Was at around 38, plugged it to the laptop to transfer stuff, took it off showed 100.. reboot fixed it but now I have to recalibrate

i tried it on my old phone and it worked. So far my N4 is still fairly calibrated.
batterystats.bin has absolutely nothing to do with the battery level your phone is showing you. Its a per charge battery history file, i.e. what you see if you go to Settings>Battery.

As far as am aware it doesn't really work? So your saying changing recovery for you helped with your battery, coz like i take it off charge and its 100% then it jumps down to 97% after a few minutes and am not even doing anything.. and i just got this phone this week. Am tempted to send it back, i don't know what to do?

That is because you left the phone plugged in for so long that it hits 100%, then it starts discharging to prevent overcharge.. so it drops to 95%, then charges again. You took it off at 97% (yes, it might still have shown 100% for a little while so you don't go and plug it in again).

is this the battery or the phones issuse?

Hi everyone im new to the forums and recently got my note 3 last week on Thursday. I have the Tmobile version.
When I charge the phone when the device is completely turned off and it fully charges and the red LED turns green, I turn on my phone and my battery percentage shows 99%, but if I charge while the phone is on then itll charge too 100%.
Another issue that I am having is that my battery dies qquicky. I don't know if this has something to do when I first got the phone because I didnt charge it once I had got the phone and once I did get the phone I factory reseted it so that I could go through the initial setup (you know the menus that tell you to put your language, wifi, gmail etc.)
I have everything turned off I have my brightness always set to 0 I don't use auto brightness. I only increase the brightness when im outside in the sun. I have auto syncing completley turned off I only have notifications from apps such as Facebook, instagram and other apps.
I Don't have anything running in the background nor do I have any wakelocks happening.
My battery life right now is at 85% I was using the chrome browser since this morning starting at 7:10am its now 8:48am. Im a heavy user I guess because I use the web Brower a lot. On the second day that I had the device I was using the web constantly it total time was 8 or 8 and a half hours with 5 and a halfs of screen on time.
I really don't wanna go and exchange the device because this is the only issue that im having and I already have everything that I want setup and am accustomed to this phone but if its the devices problem and not the battery than I have no choice but to exchange.
Im hoping that you guys on xda will be able to help me out thanks in advance
I forgot to inform you guys that I also have gps and location services completely turned off aswell

hmm from my opinion of it is when u charge a phone which is completely off. after you fully charge your phone and unplug the charger it takes more energy to power on the phone.Therefore it is recommended to charge by not switching off the phone or running any apps or games while charging it and let it charge.

it is normal. like i said never ever turn off your phone while charging it as it consume much more energy or power to turn it back on. and for a newer phone always let it die completely to 0% and let it charge fully until 100% without turn off the phone. it takes awhile before the battery being callibrated
It is normal. The GN3 drop from 100% to 99% very fast compared to the GN2.

it is normal. like i said never ever turn off your phone while charging it as it consume much more energy or power to turn it back on. and for a newer phone always let it die completely to 0% and let it charge fully until 100% without turn off the phone. it takes awhile before the battery being callibrated

I let the battery die down to 1% lastnight and then turned it off b4 it turned itself off. But I read that it was bad to let the battery die down to 0 though.

its normal. its a battery protection method i first saw in S3 if i remember correctly.
the usage you mentioned earlier seems reasonable to me. you will need to use the phone longer to get an idea of how much battery certain apps will take.
BTW, you can use reading mode to reduce the battery drain even further.
to do that, click on the more settings icon in notification drawer, long press the reading mode icon, turn it on, press the pencil icon then select the app or apps that you use most with screen on. you will notice that the screen gets a red tint when u use this mode, but for me it does save a bit more battery than normal mode.
i use it with whatsapp, music and chrome.
hope that helps!
I let my phone fully die to where it turn itself off and pluged it in the charger and turn it back on once it fully charge I unpluged it and started using it its at 95%, and has been on for 37 mins with 32 min on screen time I updated 3 apps went on facebook and instagram for a quick bit. I dont think thats normal

Looks normal to me. My N3 decreases quickly from 100% to 90% then decreases slowly.
I'am not an heavy user : a few calls, a few sms/mms, facebook, twitter, web thru apps like magazine or flipboard, calendar and task usage, mp3 (around 20 min), no gps or location (only if needed), phone mode at night in order to use alarm on morning ...
My N3 lasts 3 days (last time was 3 days et 8 hours !) where my N2 was down after 2 days or less usage.

Battery dropped from 30% to 0% in a few seconds

Battery dropped from 30% to 0% in a few seconds and phone shut down. Unplugged from car at 40%, took pics from 30 minutes, while taking a photosphere, around 30% from the batt history, phone suddenly shut down. Recharged in car for 15 minutes a day it went up to 18% and then started working fine without shutting down.

Welcome to the battery bug! Send your phone to RMA while you can.
You believe it's that problem?
It's my very first time and outside was -2 degree...
Let's see if it does it again...
I wouldn't panic yet. Custom ROM or kernel? Check under normal temperature conditions...
No custom ROM, no custom kernel.
Just systemless root on new 7.1.1 Jan patch

Hi! If I buy a new phone with a new battery, I will not experience this problem? Right?

Don't buy one without a warranty. Huawei quality control appears to have been very poor for this phone.
I use my phone during winter. We go as low at -25 and have no problem whatsoever with the phone shutting down.
You battery is degrating. Have it RMA if it's under warranty.
I just got off the phone and google they told me that they are no longer sending out replacement batteries that there will be a software update to fix the problem and to run it in battery saving mode or put the phone in safe more......really?! C'mon this is complete bs
actually, if they really did tell you that, that's not bull****, in fact, it's fantastic news. That means they were able to find the problem and that it was software related (obviously, many different devices with the same issue)
