[Q]Battery or other problem?

Hey guys I need a little troubleshooting help from the community! I have a rooted(of course) mt4g. Recently I have been having an issue that I think may be battery related. Dont think its rom related but just for info, it happened to me on darkside ROM and capy's port, both sense 3.5. I thought it was a kernel or overclock/voltage problem but it happens on any kernel and i dont mess with voltages nor overclock more than stock. So now to the problem:
My phone randomly just shuts off at times. Usually when I'm on the phone or even when I'm just scrolling on a screen! I have noticed that when I go into recovery it shows me a battery percentage at the top but when I boot the phone without the charger connected, the rom shows a much lower percentage! However if I boot the phone with the charger connected, the rom shows the same percentage as recovery does! I have the battery calibration app from the market and used that as well as wiping batt stats from recovery and nothing has worked! So with that, I'm thinking I have a fried battery! Any thoughts or help would be greatly appreciated! If more info is needed, I will be happy to answer!

From reading this, i can say it's likely the battery, but a suggestion would be to try another battery on your phone before jumping to conclusions...i've had my phone reboot itself several times, especially when i first bought the phone, but has stopped.. am currently using the Darkside Rom as well.. there's an updated version 4.0 out.... so try another battery.Also not to bash any app developer, but 4ext recovery battery stats basically does the same things as the other battery app used..For me, i shut down my phone, and plug it till i get the green light(100%), then take out the battery, wait like 1minute, put it back have the charger plugged in, reboot in recovery clear battery stats.. reboot when fully booted take out the charger..it should be good..i don't do this all the time, but i noticed doing this helps my battery in terms of fully charging..

Thanks! I will try your method while i'm waiting on the battery I ordered to come in.

Looking for advice regarding my battery life after 4.2.2.

Hey I've searched for help on the subject all over and. I'm not seeing anyone with this problem, on the contrary everyone seems to be doing better.
Anyway I got the OTA update to 4.2.2 from the. General forum a few days ago and flashed it without much consequence and everything seemed fine. I reaquired my root but I have noticed my battery is losing charge way too fast doing light browsing and use.
Checking battery use I got 2 hours of screen time with 30% of the battery and again this has been simply browsing sites with pure text. As I'm writing this it went from 70% to 68%
To list a few key things that have happened that might be important and I'm hoping anybody can help or give advice.
1) I stupidly forgot to wipe cache and dalvik before and after flashing the update, when I remembered I went to recovery and did this
2) I rerooted
3) On Friday I fell asleep using it and when I woke up it was completely drained, honestly I don't even remembered what I was doing cause I had a bit too much wine but I think I was playing an emulator and when I woke up it wouldn't even turn on so I charged it back to 100%
As I write this now I think back and problem seems to have started then.
I tried re flashing a backup, which didn't help and I flashed franco kernel reading it gave good battery.
My last idea is simply reverting back to stock and see if it helps but before that I wanted to check some opinions or advice here.
PS I have already used BBS and its finding nothing wrong in wakelocks or use (except something called AudioOut2)
As I finish this im down to 66%, definitely not normal.
Any help is appreciated.

Having the same problem.
Didn't even make it to work and was below 50%. Weird.

Did you at some point let it drain completely to 0% after updating to 4.2.2?
If nobody has any idea ill just go back to stock and report results.

Well if anybody has a similar issue or cares, going back to stock seems to have fixed the issue. Regardless I did some light testing on the battery. It shows marginal better perfomance on 4.2.2
By switching Kernel there was no change it seems but then again the test only covered two activities perhaps with further comparissons better results would be gotten.
But long story short if anybody has this problem apparently going back to stock is the way to go.
I'll keep a careful eye on the battery and gauge on regular use and if it happens again have a better idea of what caused it.

Its a program that's running or not completely shutting down.
Torrent was my issue. Uninstalled rebooted and then reinstalled.
My battery life is good now.all day and still over 80%.

Well I have encountered a completely new problem lately.
In the last week this has happened 3-4 times. I leave it charging or simply on deep sleep for a while and when I try to turn it on it won't, I'm not sure if its shutting down since when I plugged it in (thinking battery had drained) not battery charging animation came up, instead I left the power button pressed and it came up with whatever charge it had.
Not sure if its a side effect of the original problem of the battery discharge or something to do with torrent clients as 3 of the total times it has happened I was downloading something and left it running.
Not sure what to do at this point since I find no info on this or it happening to anybody else. What I find are things like it not charging etc which really arent my issues.
I will avoid using torrents on it for a few days and see if it happens again, if it does I will seriously have to consider contacting Google or Asus since this device doesn't even have 90 days in my possession yet.

If anyone is following this (really just posting here to help anybody who finds the same problem and as a sort of journal) I found this post on the kernel im running thread
http://forum.xda-developers.com/showpost.php?p=38422891&postcount=4603
Somebody replied to that post stating its a 4.2.x problem
It could also be a kernel problem with torrents as further down the posts another person complains about the same happening when using a bittorrent client
I'll post with whatever I find out.

I've been having the same problem glad to see it isn't just me.

Hi Chaps, Since my upgrade to 4.2.2 I thought the battery life was great. It stayed at 100% for ages and when I was streaming music for a few of hours and the battery only went to 96%. Superb I thought..
But, yes there is a but. My N7 now shuts down when the battery is at 32% and I need to charge it to get it to reboot as it is well drained. Is it possible to zero the battery indicator or recalibrate it for an accurate reading? TATA R.

Battery calibration, which should be done rarely, is merely a matter of putting your device through one complete charge/discharge cycle. Don't waste your time with battery calibration apps, as they are 100% snake oil. Likewise, you can disregard any misinformation about wiping battery stats, as that has absolutely no bearing on battery charge indication.
Try unplugging your battery for a few minutes, and then plug it back in, ensuring that the connector is firmly seated.

Getting pissed off here. N7 shuts down at 42% now. WTF. Is this a 4.2.2 problem? If so how do I revert back to an earlier version?

Mine is ****ing **** since 4.2.2 and its official, writing this it went from 40 to 37 the ****

I am seeing reduced battery life on 4.2.2...
I used to be able to go all day on a charge. Now I can't make it through the evening ...
I know that is subjective as I didn't indicate my prior usage compared to my current usage pattern.
But my perception is that battery life has degraded ...
As an aside, I noticed that an el-cheapo IKEA power strip didn't provide enough juice to keep the battery from draining further while using it when plugged in...
It plugged in at 20% and kept using the N7... awhile later I was in the mid-teens.
I don't use that power strip any longer....

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.

GT-i9505 odd behavior - help needed

I'd really appreciate it if someone could help with the problems I'm having.
Here's the rundown. Rooted my phone and installed a google edition rom almost immediately after buying. Unfortunately, though, as time went by I'd get frequent reboots with any GE rom I tried so I decided to go back to a custom TW rom. But I'm now getting another problem which is really odd. Basically, on a fresh factory reset 100% charge the phone starts up fine and works impeccably for the whole day until the battery goes down to 20-30%. At this point it either shuts off or gets stuck on the black screen with the white Samsung logo. It will reboot but as soon as it finishes loading up it either reboots again by itself or gets stuck on the Samsung screen. I've even tried the stock 4.3 rom and it does the same thing.
Any ideas as to what it might be? Any solutions?
Thanks

You have a faulty battery. Check serial number,if it starts with BD this is a recognised faulty batch.
If you plug your phone into charge it should boot up fine yes?
Buy a new battery and call should be good mate

I believe its the battery as mine did the same thing until i replaced it with a new one.

More odd behavior
...Taking out the battery and putting it back in stops the bootloops and allows it to start up normally again till the next charge. Any ideas because I'm not sure it's the battery? The battery lasted nearly 2 days on a full charge yesterday and went down normally this time to 0% before turning off

tried many roms still powering down, I'm lost!

Nexus 4 16gb White
bought off ebay used but in mint condition.
received it with 4.2.2 kitkat, started powering off an losing signal an data so I rooted/unlocked and started with a installing roms, from rooted kitkat roms then back down to 4.2.2 with franco kernel, 27 hybrid radio with various roms and all get the same results of the phone powering off, and earlier today I could barely keep the phone powered on while connected to usb to my pc.
no I do not have the netflix app installed either.
I have done tons of reading and some say it could be a battery issue but my dilemma is that Im about to send this back to the ebay seller and dont want to crack this phone open to check the battery connection or battery itself with the possibility of sending it back.
just hate to return this phone cause I love the looks of the white LG Nexus 4.
From my search of reading endless threads through google that no one has found a definite answer to the phone popwering off, yes found the franco kernel to help with signal along with the 27 hybrid radio.
please chime in if im missing something in my search or is this a sitting duck situation awaiting on google to send a new update??

I pulled the back cover off an noticed towards one end of the battery it had a crease along the top of it kind of sunken in, I checked the connection an put back together. but when I check the battery status is said "good or okay" cant remember which one

Would defective battery also cause signal issues? Im sure it causes the powering down problems of course.
