I'm running CM9 and have had this problem with 2 different Samsung Epics...I'll be on a phone call with, say 38% battery and all of a sudden I'll hear a system beep and look at the phone and see it's dropped to 0%, shutting down the phone. I've had different modems installed and always had the same result. Just wondering if anyone can point me in the right direction.
Sounds like old batteries.

Yeah, it seems to me like it could have something to do with voltage or something, but I've been using about 4 or 5 different batteries with the same results.
Try updating to CM 9.1 Stable, CM 10 Stable, or CM 10.1 RC5

Just shutdown phone properly
Restart the phone..
After your booted up completely then plugin the charger.. Let it be 100%

Do you think it is as simple as that? I am pretty bad about popping the battery out when I change batteries without shutting down. I charge them in an external charger (and charge the one in the phone overnight in the phone). I'll give it a shot and start shutting down properly before putting a fresh battery in. Thanks for the tip.

hi i have a
Gnex
im using
>Codenameandroid v3.3.2
>Trinity kernal
Everytime my phone reaches around 30% my phone just dies, then wont start till i connect it to a ac wall charger.
i have two batteries and at first i thought it might of been a ebay battery i purchase but it does it with both.
any help?
Try to wipe the battery stat in recovery.
I tried wiping it Ndnit continues to behave this way. Thank you for replying

Did this just start happening with the new kernel? If you are sure it isnt a hardware/battery issue, I would set it back to stock and see if that fixes it. Hopefully its just a bad combination of kernel/rom. Good luck !
You know what it might be the kernal I using the Trinity kernal experimental 537. I'm flash back to the stable version. See if that helps.

I have never gone into any such issues like this b4...
If i feel like battery drain or something like tat.. I do wipe cache and dalvik and install the ROM and fix permission in CWM...
Then it will be back again..
Its my Daily driver. So most of the time i will be on Calls and msgs and also Wifi and bluetooth will be on 24/7
Auto Sync on..
My Battery will Remain till nxt day morning and still i will be having 25~30% left out...
Well I need to know from you guys, it's not that I don't know, but need to reconfirm. I think mine is taking much lower now than it was. A full charge, say from 5% to 100%, with Stock charger?
Thanks in adv.

roughly 1 percent for 1 minute. should be charged in a couple of hours

Charging from 0 to 90% happens in no more that 2 hours I would say. from 90% to 100% the charging rate gets slowed a lot. So basically shouldn't take more than 2:30 hours from 0 to 100%.
Thanks guys. Now I remember it was 2 hours 45 mins for me too at first.
Today it took 4 hrs 30 mins. Reason? I'll say tomorrow, after confirming.

I rarely charge it to 100%, usually to 70 or 80%. much better for the battery in the long term
Any research or refrence for this longevity ? I heard its always better to charge 100% ?

you are welcome. the general rule is to try to 1) avoid charging to 100%, really diminishing return the higher it goes; and 2) avoid deep discharge cycle. I usually use 40% of the capacity at work everyday, so charge to ~70% in the morning, use down to ~30% and then charge again. charging time in this range is rather linear, about 1 percent a minute

Yeah, it happened to mine too few days back. My Note2 went crazy, taking around 7-8 hrs to fully charge from 15%. So, i tried searching about the problem on google but to no avail. Did a factory reset with cache wipe and problem solved :good:. Now it takes about 2.5 hrs to fully charge from say 10% (using the samsung wall charger with phone switched on). I can only say that the slow charging was caused due to some software but don't know exactly which one? You may as well try the hard reset if anything else doesn't work out .
P.S : Btw i'm on stock fw with no root or mod! Only did some OTA updates couple of weeks ago.
Guys, we have a changeable battery and is already writed Inside to android that it won't charge to 100%, it just shows at 100% but really it is at 95%-98% that feature came with 2.2.1 update 2yrs ago.
And we can change the battery after 2yrs for 20-30$, unlike Nokia lumia users or HTC one x or iPhone users.

Yeah, thanks. But if you've Watchdog installed then you can see which app is going over threshold and keep running on background. And yes, this time, again, the culprit was PowerAMP! Uninstalled it and voila. The same app created problem for me when I had my S2, charging was pathetically slow, even I had to go to SC and they said battery is gone. But I didn't believe and asked a techy friend and he said it might be some app, and damn right he was.
Anyway, if anyone having the same issue like mine, that is, charging duration has increased with Stock charger, then install Watchdog (the lite version will do) and see who is the culprit.
I have no idea how a top app like PowerAMP could cause this! Jeez!

OK guys not sure whats been going on but i had around 8% left its been 4hrs or 5 and its only up to 78% thats a bit crazy if you ask me. Im running a custom Rom 4.2.1 i believe i feel like going back to stock...
Where did you get 4.2.1? The kernel in something that for off from what is in the usual development channels may have an impact on charging. I'd stick with 4.1.1 or 4.1.2 for current kernels.

I had this problem also when I had the note 2 for about a month...happened twice only though, not every time. I ended up returning that phone because the mic kept cutting out. I haven't had this problem on a new note 2 yet (been about 3 weeks). So there might be something wrong with the device, i don't know.

When you plug in the charger, double check that it says "AC Charging." I have plugged mine in and gotten mixed results:
1. AC charging
2. USB charging
3. Nothing
If I get #3, I restart and usually get #1.
You can also install a battery monitor app and check the log to see how much charge you are getting.

Was your phone just charging or were you doing stuff?
More importantly, what does it say for mA in the log.?

If you were flashing a new rom or any big file. You should never flash below 50% percent. I did this the other day and it was just charging so so slow. So what I did was turned it off and let it charge. While that was happening I guess when it hits a certain percentage it automatically turns on. It turned back on and it was charging just fine. And also when your on the phone while charging the percent goes down for me as well.

I dont think your charger likes you ^_^ Jokes aside, is your charger going through an extension or straight off the wall? Maybe try a new extension or a different wall socket.

Something is wrong there. Easy candidates are:
Your battery
your charger
your cable
Do you have any way to swap out any of the above to see what it may be?

I just happened to be charging my phone while browsing the forum yesterday when I came across this thread. I'm not having any issues I was just killing time and being lazy..
It made me check my battery and I noticed it seemed to be charging kinda slow. (I had been plugged in a while and hadn't gone up much) I checked battery in settings and it said charging USB. I was plugged into the wall outlet. Strange indeed!
I unplugged the usb from the phone then plugged it back in and it switched to AC. It definitely started charging faster after that.
I never would have thought to check this so I'm glad I was snooping around.
Just figured I'd share my experience.

I've had the same problem with slow charging every once in a while. I think it has more to do with the kernel and/or rom. I had times when it took overnight for the phone to charge. Now it charges full in about 2-3 hours.

Either a CPU max run state...or a serious wake lock...or both..
Zero lemon getting drained like that is a serious problem...
I would suggest a "complete" wipe...and the flashing of a rooted stock rom as a test base...
If the device still exhibits the behavior...then a hardware issue may be at Work here...
If the device gets hot to the touch....then get the device to a stock and clean state...so some unmodified testing can take place...
Let us know...g
