[Q] Nexus 7 Battery?

hello guys, i had recently bought a nexus 7 16gb about a month ago, and while i was gone for the weekend, my little sister was using it. When i returned, she said it had completely died and she had been charging all night but was still at 0%. I've tried the common fixes that everyone has tried, but for some reason my battery says it will not charge, but yet i left it on the charged for over 6 hours and its still at 0%. When i got to Settings > Battery > it has been unplugged for well over 18 hours. is there any fixes out there or any way to reset the battery stats? i'm on 4.1.2/ stock non-rooted. can post screenshots if needed. i dont want to keep charging and risk overcharging my battery or anything like that. It doesnt get hot, make any weird noises or anything. Thank you in advance!

I think you have loose battery connector.
and please post questions in Q&A section (xda made it for a reason)

Sounds like a loose connection in the battery.
If you dare, pop the back open and then check the flex cable.

When she said that 'it has completely died', did she mean it just randomly went off when she was using it and the battery level wasn't empty, or did she mean that she had got the 4% warning and kept using it until it died? This is important.
If it was the former, then yes, the battery connector may have come out. If it was the latter, it's very unlikely its anything to do with the connector. I'm sure I've seen something before about a problem when someone has used it until it has completely ran out of charge until it switched off.

Ask her by the scruff of neck, did you drop my n7. If she say's yes, either send in for repair using your warranty or pop off the back. Since it is recently bought - probably better to use the warranty...

thank you guys for the replys, i dont think its a loose battery connector, i popped the back off and everything seems to be okay, i let it charge for like 8 hours and then have been playing with it for about 9 hours now, its what it says in the settings, but it still says the battery has 0%, but its functioning just fine..? idk, its pretty weird but its running completely normal..

Your charger might not be putting out 5volts

thank you xateeq, Wilks3y, and knuckles, it was just a loose cable. Also, when i had the back off, i noticed there was 4 soft buttons but only three that are pressable (power, vol up and vol down). did they have plans to make a camera shortcut perhaps? also, i realized there were two screws that are missing out of the holes. is that a normal mishap on their behalf? thanks for the answers guys, just a little curious.

Yes, that's normal, because they caused the screen lift in the first parties of N7, and without them the issue seems to have been resolved

Yeah when you had the back off you would have seen the empty square bit where there was originally going to be a rear camera, before Google told asus to take it out of the design. Sure someone from the modding community will be working on that.... In fact i saw a thread where they found out what camera was going to be in there, and they were in the process of trying to get it in and working...

Nexus 4 Shuts Down Randomly and Battery Problem

Help people, I have the nexus 4 for over 3 weeks and great but a few days ago when it was nearly full battery (around 80% or so) suddenly shutted down and I couldn't turn it back on until after 1 min or so plugging in. I did not care about it the first time ... But today, after having it charging about 2 or 3 hours I disconnected the cable to use the phone and the battery dropped from 90%+ to 8%, so I connected the cable and put it back to 100%, used it for 1 hour and it suddenly dropped back to 2% from 80% and then shutted down instantly.
Here are some screens.
Help please, and yes I have used the search function, but didn't find the solution on other posts.

What apps have you installed lately, maybe there is a rogue one. Install BetterBatteryStats for app behaviour and Cpu Spy for deep sleep issues.
Are you rooted? Custom rom or kernel? Undervolted or overclocked?

I'm not rooted, all at stock. I didn't touch the voltages, I didn't do anything. I installed some games (vector, pudding thd, order and chaos) evernote, mega manager, pulwifi.
I'll install betterbatterystats and cpuspy, thank you.
Edit: look what happened to the battery now...
Also I attached a pic of the cpuspy, I can't install betterbatterystats because it costs 2 dollars

I think there is a free version of BBS on XDA , here http://forum.xda-developers.com/attachment.php?attachmentid=1240843&d=1344068311. Consider buying it on Play in the future if it benefits you.
Battery levels can be inconsistent at times, especialy after deep sleep.

I see nothing abnormal on usage, just use the phone and see if this behaviour continues. If it does better do a factory reset or reflash the latest factory image.

Okay I'll uninstall the latest apps I installed and will use the phone normally, if this happens again I'll do a factory reset and if the problem continues I'll call google. Thank you :good:

I wish I could be more help but I had the exact same issue. I could not figure out what was wrong with it but I had previously broken the screen and sent my N4 back to LG for repair. Since it was still under limited warrenty from that repair I sent it back to them again. They said they replaced the charger connector. I got it back and it seems to work fine now.
My issue started after I updated to 4.2.2 I believe. I don't know the root of it but my advice would be to do what you said and call Google or LG.

Thank you anyway

Similar issue here - I've been using the same apps since I first installed them after N4 purchase (meaning no new apps/games installed in the last few days and no settings changed). Took a nap for a couple of hours and woke up to see N4 completely dead - 0% batt. Charging it now and looking at partial wakelocks etc, havn't seen anything out of the ordinary. Hopefully it doesn't occur again but in the meantime still looking for a reason why this would suddenly happen.

Are you guys using the stock chargers? And charging through mains?

Yeah, am on stock JB 4.2.2, unlocked and rooted though, no other change like new roms flashed or anything. I use the stock charger and charge through mains.

I think there have been a few threads with this issue and nexus4s even prior to 4.2.2 and supposedly it was hardware. I called support while talking it through she had heard a few similar cases and it seems to be a hardware/software design issue. My wonder is how can I enforce 'never deep sleep' because my kernel doesn't seem obey.
I woke up this morning with the indicator light on but phone dead requiring reset (charged though - if not overly so). Just now it died again while sitting on my desk at 80% charge and deep sleeping again.

I've read in a few places today the stock charger has been causing a lot of the charging issues and plan to switch to my old g2's charger tonight

Just RMA'd my nexus for powering off for no reason - would do it a few times a week (and extremely buzzing earpiece - which I was living with), never had a problem putting it back on though or had issues by battery levels being eratic) did quite a bit of testing over the space of a few weeks and found it continued to do it after wiping/fomatting everything and on Stock 4.2.2 non rooted and locked BL. As far as I am concerned if its still doing it with the stock out of the box set up its a hardware fault.

Mine has powered off unexpectedly twice in 30 days. Should I get it rmad?

Dunno about that its up to you mine was doing it 2-3 times per week. I would wipe everything including userdata, reflash stock rom and monitor before going through the rigmorole of the RMA to make sure its deffo a hardware fault. Biggest problem with the RMA is the fact they put a hold on your credit/debit card for the price of the phone. So basically if you don't have the funds available you are shafted (I think you would have to send off to LG in that case).

I got the same problem ..just that my n4 back cracked while was charging :-\

maybe you should try to flash other kernel and rom if you cant solve this issus. if your N4 is unrooted then just bring it to LG store, you got warranty rite ?

Ok, this has to be glitch....

How is this possible? Last night my Nexus 7 shut down at 14%, right after the battery warning.
Fully charged afterwards and not touched for 12 hours. This has to be a glitch.
Anyone know if it's possible to reset the battery stats?

Shut your N7 down, put it on the charger till it is really full, then power up your N7 till it's fully booted, unplug and you should be good to go again. Have had a similar problem and this solved my problem

Read the thread again. He is asking how to fix his BUGGED stats, not what is the latest trend in illusionary battery tweaks.
If his database is bugged and not being reset, nuking it is the fastest way to fix ****.

Rgrds,
Ged.

ok no need to calibrate the battery stats in this case. Just reboot and the problem should be gone.
Note: you will see the stats will reset on the next charge.

Thanks for the replies.
It seems like Fotogravin's method did the trick. Though the initial boot required me to hold on to the power button a bit longer than usual.
On another maybe related note, has anyone found that the Nexus 7 sometimes charges slowly? I left it on charge from around 17% and after 5 hours or so, it only charged to around 70%.
It's not the first time it's happened either...

I'm experiencing this exact series of problems currently. No amount of reboots will help. It decides at around 15-20% that it's actually dead and powers down. Now I'm sitting here in TWRP recovery, full brightness, and it's been running for 10 mins now without problem. Talk about dead battery....NOT!
I'm going to let this recovery menu run til it ACTUALLY dies, then charge it from 0% and hope that it will actually run down correctly.

Battery charge values

Hi all!
I've some strange problems with mt nexus 4 battery values.
Today i had 59% of battery and i plug it to the original charger. After 2 hours i saw the battery with 100% charge value. OK. Nothing wrong here. I rebooted the phone and after that i had 84% of battery.
This is happening almost every time i charge my nexus 4.
I had stock rom with franco.kernel updater. Now i have paranoid Android with The same kernel.
Any idea about this?

Have you been dirty flashing a lot?

your battery reading needs to be recalibrated.... Charge full than use until it shuts down...than charge again fully, at 100% reboot phone & connect to charge again.....
You also can try "BatteryRepair.apk" from market..most of the time it helps to recalibrate..just install, open & follow on screen instruction....

I had the same issue with my previous nexus 4. Did you ever get your screen/display changed? Or do you charge your phone overnight? Do you rely on USB charging a lot? If any of those answers is YES, its probable that your battery has gone bad (as mine had)

I don't think that's the solution, but give a try to this free app from the play store: https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=it
I always thought this problem was related to rom development but I'm not sure. It happened to me with CM11 at the very beginning in november, and then it just stopped. Since January I'm on slimkat, at first it didn't happen and then for a few weeks i noticed the same problem you have, now everything has been fine again for the last two weeks.

I had changed my display and i charge over night.
I've tried the calibration 2 days in a row (battery at 0%, then charge till 100%, reboot, charge till 100% again). Yesterday i had 90% after the reboot. Today i got 91% after the reboot.

I'm gonna try that app. I rebooted the phone around 9am and now is almost finishing the charge. The battery lasts till tomorrow with my normal use of the phone, but i tough strange that every time i rebooted the phone, i lose battery % :s

Just try avoiding the charge to 100%->reboot->charge to 100% again for a few days.
Don't let it discharge till 0%, connect the charge when you have 1%-4% left and let it charge till 100% with the phone on, and then use your phone normally.

Please go through this thread. A couple of other members (myself included) finally deduced that if you ever have your display changed you NEED to get your battery changed as well. Trust me on this, get your battery checked once. It WILL be bloated. Also, if upon restarting there is a break in the battery graph and there is a significant drop/rise in battery level, that is another indicator that your battery is going.

I've been reading that thread but for example, what happens to me it's nothing compared to the first topic of that thread. I only miss sometimes 10% after restart, sometimes 5%, sometimes nothing. From what i understand, in that thread most of users with battery problem had like 80% and after reboot they only had 2%, or 0%. Thats different i think, but i'm not expert on this subject
Anyway, installed the suggested app and calibrated the battery throw the app. For now i have this data (Paranoid Android Beta6+Franco.Kernel.Updater r201):

Try Battery Monitor Widget from the Market - you can see what current the phone is pulling, and if indeed full charge is reached. There are also calibration tools inside - the app calculates the real capacity of the battery, for example. If it's a long way from 2100mAh it would be a sign you need a new battery.
Though like everyone else, I think it´s a software problem. With previous Android phones I had to be careful calibrating, flashing etc. With the N4 I've had no such issues in the year I've had it. That app can help you sort out battery calibration though.

Can you tell me The dev name? Got 2 battery monitor widgets :s

This looks normal, although if you see a break in the battery graph and huge drop/rise in battery then its definitely done for. However its not the case with your phone, so relax

Well this evening i left the phone with 60% of battery and at 7am the battery was death. Just ordered a new one. I've only one problem. I dont have any plastic screw to open it. I've the torx t5 screw only.
Any advise to the new battery?

10-20% (+/-) battery drop after a reboot

I've already tried doing a battery calibration as recommended by many people on the V20 threads, buts this is still happening to me. If I reboot my phone, when the phone comes back on, my battery level has dropped 10-20% (give or take). I know reboots can consume battery, but this is quite a large consumption.
Last night, for example, my battery was at 60%, but after I rebooted, I was immediately at 25%.
Again, I've down the whole calibration thing at least 5x now, and it hasn't helped with this. So now I'm wondering:
1) Is anyone else having this issue, especially with the same variant as me (see below)
2) Is this a Nougat 7.0 issue
3) Is this a battery (hardware) problem. I ordered one of the spare battery kits that come with an extra battery. I figured that I'd try the new battery, but if it doesn't help, then I have a second battery anyway.
ATT variant (h910)
Running on ATT
Battery life has been mediocre to poor, and I've disabled so many features by now that it's gotten kinda ridiculous.

Try the battery if not, warranty, that's not normal

Yeah, I didn't think it was normal. I was hoping it was a Nougat 7.0 issue, but I wasn't hearing anyone else with this issue. And as stated too, my battery life hasn't been great. I make it through the day, but only of the phone isn't used much. Otherwise, the battery will drain pretty fast.

What was your calibration method? Running it down to zero once should be good enough then charge with phone on or off without using it to 100%. If still doing it try your other battery. If still doing it exchange.

I pretty much did as you just said.
I ran the battery down until the phone powered off. Then I kept attempting to power it on until the LG logo stopped showing up and the phone said that there wasn't enough power to turn on. Then I charged the phone to 100% while phone was still off. Once it hit 100%, I left it charging for another 2 hours.
Overall, it helped, but once I reboot the phone, the battery always drops quite a bit as stated in my first post.

Do you have twrp intalled? I think Lg has a problem with it's battery stats because of the removable battery. On my v10 I had two spare batteries. When one got to like 4% I would power down and pop in the new one. When back on it would read the battery at like 19% or something to the liking. I had to leave my phone off for about 30 secs between changes. I was having similar issues to what you're describing with my v20. I ended up formatting data in twrp and then set my phone up old school style with manual app installation and no data transfer whatsoever. I let the phone die completely and then charged while on uninterrupted. I then at 100% unplugged it and plugged it back in for 20 minutes. My battery has been perfect since. I would also note similar issues on the G4 too. I think this is the cause for the notorious Lg bootloop.. My G4 did it right before the battery drained out and so did my V10..

I had that problem on an old note 4. But not a drastic a jump in percentage. Brought it to Samsung and they just changed the battery and the problem went away.

I have the ATT V20, which doesn't have the bootloader unlocked. So, no TWRP.

I heard similar issues when I had my Note 4, but in this (using a new Android OS that not many other phones have yet), I wasn't sure if this was hardware or software. I really hope the second battery fixes the problem!

I'd rather not since I don't have the time to re-setup all the programs I need for work. It takes several days to get everything up and running again, and after having to do this 2x already this past month thanks to the Note7, I don't want to go through it all AGAIN. Its too much of a hassle and shouldn't be necessary since this is a new phone. I mean, w y reset a new phone that's only a couple weeks old?
