Cheers,
I've been having this weird problems with my N7 32GB recently, it started to happen about 3 weeks ago, then it stops and starts again this week.
It seems that the battery percentage is not being reported correctly, I remember the first time it happened is that I still have > 50% battery, then
the device shutdown and booted and then the screen flickered and shutdown and booted again it went on in this cycle for about 2mins and every it
went into this cycle the screen flickers which is kinda alarming and asked that it be connected to a charger. This week it happened again, I have
85% battery charge, and then device went into the same shutdown - boot, cycle and asks to be connected to a charger. And every time this happens
when I first boot the device the battery percentage shown is way less than that of the reported charge just before it shutsdown. And today it happened
again, the device has about 70% charge and it just shutdown, but this time without the shutdown-boot cycle, so knowing of the issue, I attached it
to my usb to charge and booted it, and it shows that it only has 11% charge.
Any idea on why is this? and how to avoid this issue? I have already installed Battery Widget Reborn and DS Battery Saver.
BTW, Im on stock non-rooted 4.2.1
Thanks.
These issues started up when I was on slimbean ROM and franco kernel r102, but I don't think its a software issue. My phone would randomly reboot at around 70% battery and sometimes around 20-40%, and when it would restart it would show 5-10% battery and sometimes wouldn't start because the battery was completely dead. I recalibrated the battery by removing the battery bin file after a full charge and did all the necessary steps to do it over and over again. When that didn't work I did a full wipe and flashed stock factory image. I even recalibrated battery again, and now the phone shut off over night (5 hours in according to the battery stats), and when i turned the phone on again it showed 10%. I'm scared my charger sometime down the line messed with the micro usb port and shorted my battery or something.....whats even freaking weirder is that I would have auto rotation screen issues where when I would plug my phone to charge, auto rotate wouldn't work even if i enabled it, then would start working again randomly....any help would be great before i drop another 300 on a new nexus.
I just calibrated my battery in my samsung galaxy s4 because ive heard that it speeds up the charging process, but then after 10 seconds my phone reboots/restart and when its turned on again ive got about 10 seconds to do something untill it reboots again. I have searched some forums for this problem but the only problem i found when the battery was drained. But ive still got the same amount of battery power(don't know what its called, so i call it power). Please help me with this, i have tried taking out battery and having a charger connected but it don't help! I have a rooted device btw. Please help me ASAP!
Battery Calibration was ok for older phones (before the galaxys). But u can do this:
- After you reset your battery stats, it is suggested to do a few full battery circle (use til dead, full charge, rince and repeat). You should be fine after 2-3 circles.
Hmm

But i cant use the phone?
turn off your galaxy s 4 and load it completely auf.Danach you let the battery for 15 minutes outside. Then you put the battery back in and booting into recovery, there you make a full wipe and reflashing a new rom, then your problem should be solved.
Does anyone else have a massive battery drain in Kit Kat? I can charge my Nexus to 100% and in an hour or two it's completely dead with blinking red light. I tried restarting to bootloader when it was at 5% but it was still on for like a half hour. Once I restarted my phone, my battery read 0%. I'm thinking it may be time to change the battery if no one else is having this problem.
I suggest you to reset the battery stat from the recovery. The probability that this works are low but is better then nothing.
How do I do that from recovery?
Edit: phone was charged to 98%, rebooted into recovery to see if I could wipe stats in TWRP, rebooted again, phone reads 28%, 3 minutes later it read 66%.

To wipe battery stats in TWRP:
boot into TWRP recovery
/advanced/File Manager/
folder /data/system/
click batterystats.bin
click Delete
reboot system
If you can't see the folder, you need to mount the data folder.
Well I switched to Philz Touch, do I have to do the same thing then?

You should have the wipe battery stat under advanced in your recovery.
The right step to follow are:
1. charging the battery FULLY
2. wipe Battery Stats
3. don't charge the device until the battery still turns off your device because it empty
4. now again FULLY charge without interruption
Wiping battery stats does nothing, see here: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/ . Sounds like your battery is borked. May need to send away for repair. Are you still under warranty?

Yeah I figured. Thought it was a KitKat bug at first but then it started getting ridiculous. Phone was at 70%, started taking a photosphere, phone shut off, and when I turned it back on it was at 3%.
No its not. Bought it off Craigslist. Just gonna order a battery off eBay for $18 and replace it myself, see if that fixes anything.
I just got out of a similar problem.
My battery percentage was jumping all over the place.
It would charge fully in about 5 mins, and die in about 20.
Everytime I restarted the phone, it would read a different percent.
I ended up running the phone on full brightness, with like everything turned on to drain the battery all the way down.
& Everytime it would shut off cause it had no battery left, just restart it and keep draining it until when you reboot the phone it no longer turns on(because the battery if fully drained of course).
That's when it is really dead.
Then just charge it to 100%, and keep it charging for about 20 extra minutes once it hits 100%, and now it's back to normal!

That really worked? Any problems with it since and is this a common issue with the N4? For some reason it won't die when it's in the bootloader even though the percentage read 5.
So yesterday it was so dead that it gave me the red blinking light, should I charge it when that happens again and should I leave it off while charging it or turn it on and not touch it?
How many times did you have to do this until it straightened itself out?

I am currently having WakeLock problems, but I do not beleive this was the cause.
I was able to restart it after it died about 4-6 times, till it was fully dead.
Then I charged the phone, and kept it off the whole time.
I installed wakelock detector to make sure that wasn't the problem. I had this problem on the stock rom even before I rooted. So the problem hasn't persisted since?
Hey all,
so after 2 years using my N4 I bought a new battery since I exchanged my display and sort of damaged the original battery (it was bended, smelled strange (could also be the glue) and I had the feeling it performed worse).
In the beginning I was satisfied but now after some time, I have some weired charging effects:
Using the stock rom (Android 5.0.1), I charge the battery to 100%. If I reboot the phone, the battery percentage dropped back to something between 50%-80%. It will the charge back to 100% within a quite short time. If I reboot again, the battery percentage dropps down again, but not that much. This can be repeated several times... Further, if I boot into recovery (TWRP) after reachin 100%, it also shows something between 50%-70%. After changing the battery and flashing Lolipop, I used an app to "calibrate the battery" - don't know if this helped smth or messed up everything.
Furthermore I noticed sometimes, that battery percentage drops down instantly about 20-30% within a sec while using the phone normally.
Is it just a bad replacement battery? Or is it a issue due to Lolipop (can't say if this will happen with KitKat since I changed the battery using the developer preview and stock Lolipop only)?
Right now, I'm trying to charge the battery while beeing in TWRP and see what happens then if I boot the phone.
Edit: Within minutes, battery was up to 100% in TWRP too. I rebooted TWRP and it's now back down to 58%... So it seems that Lolipop is not the reason.
