My Nexus 7 is doomed...

A few weeks ago, i flashed a stock rom on my wifi nexus. I was happy with it until last week. Charging became incredibly slow - 30% over 8 hours. I threw it in my bag and wheb i got home 8 hours later, the battery was depleted completely. I couldn't turn it on. I plugged it in over night and it stayed at zero percent. I booted into recovery and reflashed my stock rom abd wiped my data. Still didn't charge. I tried going into my bootloader and hitting power off and then plugging in, but it still wouldn't charge. I can't flash my backup because it's on my card that i lost, and even if i had it, i wouldn't be able to keep it on long enough to flash it. ADB won't run on my pc and i don't know how to use the program anyway. What can i do to save my device? Please help.....

Not the average flasher knows how to tear apart a device - including myself. Anyways, this thing won't power up at all? You tried leaving it plugged in and booted into bootloader? If so, sounds like a hardware issue or the battery is defective.

I would be willing to bet that your battery connection came loose. Start at your USB port with a thin piece of plastic, such as a guitar pic. Work your way around the device and remove the back.

It's not too difficult. iFixit has a good tutorial on it. http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1

Sounds like my device... only I even can't get into the bootloader nothing... Someone suggested that the battery got so far depleted that it will nor recharge.
However seems you at least can run the bootloader... for me it just stays black ..... nothing nopes nadda

I heard that was a good site. I'm more scared of screwing up any hardware than doing the actually tearing apart.

I can boot for like 30 seconds and then it shuts off. I've tried the solutions in the thread link above; however, i still think it is a software issue. I've used other roms that had really slow charging, but i was able to switch to another one before the battery got depleted. So i think my best bet is to somehow get a new rom on my device somehow. ADB won't run on my computer. It just flashes a command prompt on the screen for like half a second and closes.

What kernel are you on? The kernel is what does the charging operations.

I had a similar situation in that after the battery died, I got it to the point where I could boot up, but after a screen timeout, it would be dead again. Finally, I got it booted again (while plugged into power) and immediately went to developer options and checked the Stay Awake, never sleep while charging. Keeping the screen awake kept the N7 on and it charged up.

Funny my Galaxy Nexus started doing this crap on me too after I updated the rom and kernel. The phone and battery are only 2 months old replaced in April.
Occasionally it won't take a charge. I have to **** with the battery, removing it several times. Then all of a sudden it starts charging again after 10-15 resets.
Haven't had a problem in a while. Typically hits me like every 2 weeks.
No problem on N7 though but it happens. First thing is to change your kernel and rom to something else. If still draining, flash stock and relock, unlock, relock, wipe. Boot, upgrade to 4.2.2 and test.

i9505 strange battery problems

Hi there.
I own my stock Galaxy S4 i9505 for 2 months now, and since a week or 2 it started to act strange.
The phone turned always around 20% battery off, and started to freeze sometimes in normal use.
I did today a factory reset, since then it turns off around 63% battery.
Ill try to charge it for 100% and let it charge for some more hours, and do another factory reset then, but i doubt its a battery calibration problem.
Do you guys have any tip that could help me, or should i just return it to seller?
Thanks in advance!

Don't know if this will work but factory reset the phone then use until battery dies then charge whilst off untill 100% may be battery calibration issue.
Let me know how u get on mate

It's definitely not a calibration issue as that has no correlation to battery life. Thee OP is facing a hardware issue- either a defective battery or PMIC.

similar problem
I'm facing similar problems. sometimes it last for a day and dies at 10% but sometimes it dies after a few hours with still 30 to 40 % battery left. After the phone switches off automaticaly i'm not able to restart unless i plug him in.
I tried a lot of things like flashing custom roms, factory reset, flash stock rom with odin with factory reset afterwards.
All with no luck.
It all started after flashing I9505XXUBMGA-PRE-ROOTED
Currently i'm on an older version suited for my region but the problem is still there.
I'm considering to buy a new battery. Can anybode help me please?

You are not alone.Many people report that problem with the original battery.Have a look at your battery if it is/gets fatter.
Buy a new one or go to the shop where you bought the phone,maybe they give you a new one.

I9505 problem battery

hello,
i'm using a galaxy s4 since 3 months now but i have a problem since this week.
my phone looses signal at some point. nothing that i know that can cause it. it doenst turn back when activating airplane mode and then deactivating this mode.
and when i turn of the phone it turns on to the standard galaxy S4 logo and then samsung logo but then it just dies.
i have to connect it to a charger and then it works.
also my phone doenst give an announcement when my battery is emptY. it sometimes displays 15% on battery and then it dies. when charging the battery icon displays and the battery is completly empty?
i looked at my battery and it is a little bit swollen and i only use official charger at night from samsung and during the day one of nokia
anyone else with this problem?

I had the same issue. My battery was also swollen.
Replacing my battery solved the problem. At least till now (fingers crossed)

Exact same issue here. Replaced the swollen battery with a new one and its working as usual again.
Strange that original battery lived only a few months.

I´m experience that too. My battery is going slowly... Every new charge theems the phone lasts less... Battery issue?

I have experienced this during my Galaxy W days. And samsungs centre's technician told me it's because I charge my phone while using it for hours, and it's straining the battery causing the gradual swell. Since then I never plug my phone while using it and until now my s4's battery is still good as new. My phone's 4 months old already.
FYI.

I'm sorry but this doesn't make any sense to me. Maybe it's Samsung's was of "diverting" the fault to the user. The battery should not swell because you're using it while charging. I've never had this issue with with my other phone, which had a very small battery by design and had to stay plugged in if I were to get any real use out of it. Over charging does gradually reduce battery life but no swelling.

I have also had this issue. Started a few days ago with random reboots and signal losses.
Has anyone taken it back to the shop? Will they want to keep the phone for testing? I just want to replace the battery and not have to send my device away for a long time. I need to know because it's rooted and if they see that the warranty will be voided. Phone is only 3 months old, this really shouldn't happen.

I think it's battery issue. Maybe Samsung spares on the battery this time... on s3 it was on memory.
I solved this issue flashing a Google edition romantic with a full wipe (formating internal sd). Take some days with this Google edition tom and battery drain stopped. This can be related to last firmware releases. Just guessing...

[Q] Fault battery indicator [SOLVED]

Hello, :fingers-crossed:
i'm having a lot of troubles with the battery of my Nexus 4. I'll try to explain this strange situation...
Few days ago i noticed a ridicoulous battery drain while i was, as usually, listening to some music with my bluetooth A2DP headset Jabra HALO2. It was something like 1% every less then 1 minute. At first i thought it was due to a recently upgrade to CM10.2M1 (which is a monthly build of Cyanogenmod on 4.3) or due to a 5 minutes fast charge from the 2A charger of Nexus 10 that could have "upset" the battery.
At first i started focusing on the software side problem; i tried CM10.2RC1, CM10.2, stock 4.3, stock 4.4 and now CM11M1, and, while doing all of those wipes, i noticed that not only the discharge was insanely fast, but even the charge! The graph on the setting panel is almost vertical while cahrging, like 3% to 40% in 25 minutes.
But that's not all, sometimes, after rebooting, i noticed a battery level different from the previous boot, so i decided to wait a full discharge and then fully recharge it. I have waited the 0% (not so much time ) putting the screen always on and the LED flash too, then, i tried few times to turn it on and every time, after the boot screen disappeared it immediately started to turning off due to 0% battery.
Moreover, for being certain, i tried to turn it on in recovery and wait how much time it would take to consume the lasting charge on the battery. Surprisingly, after 30 minutes it was still there! I tried a reboot into system, showing me a 10% remaining battery (WTF), which discharged to 0% in like 3 minutes. Now i'm waiting the whole night the real discharge in recovery with screen always on, hoping that a full recharge could fix it. I would like to evidence that the phone do not overheat during both charghe and discharge, so i guess the battery itself may be ok.
I'm still not sure if it's a software problem, and i'm worrid if it could be an hardware related issue. Maybe it could have been the charge from the 2A adapter.
I really don't know what to do next. Someone knows how to help me?

EDIT:
I've done a full discharge until even the full hybernation has been shutted down, but seems that it hasn't solved anything. I've also noticed that in the battery stat is missing the display consumption (WTF?!?). Maybe it's a CM11M1 bug, it happen even to my Nexus 10. Here other shots:

EDIT:
I've noticed just now that while I was waiting a real full discharge of the battery the TWRP couldn't show me the battery percentage. Really strange...
[SOLVED]
In summary, the problem was the combination of kernel+ROM. The CM with his kernel on N4 was consuming tons of electrons. I tried Purity+Hellscore, now i reach few days of low usage and one and half of medium usage

How old is your phone? You might be able to get a replacement from Google under warranty.

I don't think it'd be the 2A charge, I use the 2A charger on my battery all the time.

It have 9 months, and yes is still under warrenty, but I've bought it in Spain, and I live in Italy. I think this will be hard to solve

I have some strange problemi too.
Sometines the phone reboot itself and the battery drops (i tried to flash all stock: recovery, bootloader,ROM ecc..)

It could be a faulty battery.. Read this topic, it looks like you have the same kind of problems.
Do you also have simlocks/loss of network connection?

I've already read this topic, i think the source of the problem may be related with mine, but symptoms are different. It is strange that this happened 9 months later!

Gully discharging the phone, rebooting, discharge again if any, reboot. Connect charger, charge full. Reboot, charge full again if any, reboot. This always worked for me.
You can also try to fully discharge, completely power off the phone and let it fully charge while powered off ( only a white battery should be shown on the display).

Unfortunately, no. Probably it is a battery related problem, i'm going to replace it and see what happen. In the meantime not even PurityROM+HellsCore kernel may handle this battery draining...

[Q][URGENT] Galaxy S4 LTE Reboots

Hi,
I haven't asked questions in a while but this one is beyond me. I have researched around but there's so many different types of rebooting errors I can't find one that matches my problem.
My S4 reboots to the Samsung logo where it says I9505 and then shuts down and repeats the boot to the same place back to the splash screen and does that over and over again. However if I connect it to the charger it is fine. So right now I'm using my S4 with the AC charging in.
Battery stats claim my battery health is good but the battery itself has swollen up (so do I need to replace battery?)
If I take it off charge I can use it for a few minutes but then it'll turn off and if I start it up the splash reboot process starts again. Some times if I leave the phone for a while it'll work but again for a few minutes.
Is this a battery issue or the phone and do I replace battery or send to repair.
I'm running official 4.3 and never been rooted on this device

This a good battery failure diagnosis!
So go to your service shop and ask for the free battery replacement. this issue is well known at Samsung.
For more info just google it. As exemple:

Please stop charging it because you risk to make it to explode.
