I noticed yesterday my battery seemed to be draining very fast so I rebooted it, yet 2 hours later I noticed it was still draining as the same rate. Then I noticed I couldn't turn my WiFi or BT on. Multiple power cycles and turned off phone completely, also removed the battery and replaced it with a spare, still no joy. It also won't turn on unless it's plugged into a charging cable.
I switched it off overnight at 15% batt, in the morning I switched it back on and found it had somehow drained to 0% even though it was off overnight.
I've been charging it today and it's taking 2-3x longer than usual, something is still draining the battery.
Any ideas on what the cause is? I think it's hardware related. I tried to take a screenshot of the battery screen but for some reason my screenshots turn up blank when I transfer them to PC, but all the previous screens are still fine.

If the phone was off yet the battery still drained, that means you have a bad battery. There's nothing to use power while the phone is turned off.
Batteries still lose charge over time even when left inactive, but a good battery won't lose charge in just one night.
It's draining with both batteries (standard and extended 5200mah), neither of them had this problem until yesterday.
Extended batteries are fake, buy a new genuine battery and let us know

It's an Anker battery which are really reliable. Like I said I tried the original Samsung batt as well, that also drains very fast and charges slow, same issue on both batteries and they were both working fine before. Started draining the same time the WiFi/BT stopped working. Happened in the middle of the day, just had it sitting on my desk.

my phone battery was inflated, so I had to buy another, the phone was working fine with the new battery for a few days until it stopped charging the battery, my phone will not charge the battery when it is on, I have to turn it off to charge the battery, when I put the old battery it charges properly, turned on and off.
know any solution?
Sounds like a battery problem. You'll need to exchange it.
Ok so my phone will not charge over 60%. Anyone else having a problem? Going to go back to AT&T and swap batteries to see if it changes anything.
Is there a way to clear the battery memory? I have tried to run it all the way down, then back up but it hasnt changed anything.
Mine wont turn on unless its above 5%, even if plugged in to the wall. I thought it was a brick, doesnt look like it charges well while powered on.
Mine wouldn't charge past 50% most of yesterday. I plugged it in to the wall for a few hours and left it alone. I returned and it had started charging. It also charges very slowly for me over USB.

Dont use the phone while its charging.. it will take forever.
I wonder if the charger can't supply enough juice to the battery.
It does have the biggest battery of any current cell phone.
Has anyone with these issues actually charged the phone while it was off?
I fully charged the phone powered off as soon as I opened the package and I havent had a problem charging at all..
I wonder if anyone knows what apps are active and syncing in the background when the screen is blank? On my previous myTouch 4G (not-so dearly departed), I would start the day with a fully charged battery. For an experiment, I did not use the phone all day until 5pm. When I unlocked it at 5, I had 30% charge left. So where did it go?
I had power saving on, and all social network updates turned off.
I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
So I noticed last time that while the phone was plugged in to charge, the battery started to drain instead of charge, even though I wasn't using it, which was kind of odd since it drained pretty quickly. Unplugging and plugging back in seemed to fix the problem, but when i tried to charge the phone today, somehow the battery instantly jumped up to 100% and it doesn't show up as charging.
Is this a software bug, or is there something wrong with my battery?
I've been having similar issues. i would leave my phone plugged in all night and it would be charged to 80% when i wake up in the morning.
Yeah, sometimes mine charges really slowly too, but in the screenshot the battery doesn't even charge and drains faster than when it is idle.
Hello, it has been happening to me for last 2 days that when I put the phone on charger, the battery sometimes charges at an extremely slow rate (14% to 23% in 1.5 hrs), and sometimes it even discharges while the charger is connected. I am attaching the battery screen here.
You can see that first it goes down from 100 during morning to evening. This is normal behavior owing to my usage. Then I charged it and up goes the curve with a high angle because I use a good charger. This is also fine. Then I disconnect and heavily use the phone again and then put the phone on charger overnight. This is where the problem starts!
Now you see, first of all the battery starts going up then it suddenly starts dropping while still on charger. I woke up to find 23% battery after charging overnight. I noticed in the screenshot that my phone was constantly waking up all night long, may be this could have been the problem. So I connected it to charger again to see the battery level rising in front of my eyes. But again, after 3 hours I found that my battery is 51% and the curve has started to fall down again, and this time there were not enough wakeups.wakelocks.
I am using a powerful charger. It is made in china but it charges all the phones in my home perfectly. I also tried on another charger (also probably china) with the same results on my phone only.
I am using the stock rom, unrooted (can't root version 182.*.*.*)
Do you have thinks running in the background while you charge? Mines charges a lot faster if I turn off internet, kill background apps.
Also is it overheating while chsrgeing? You get a better charge if the phone stays cool
And third your phone might think the charger is a computer. I say this because mines charges really sloe when I connect it to a computer, like 12% per hour. Try a third charger, diffrent brand and wattage compared to the ones yoive tried. it might help.
yes there are background apps but there hasn't been a change which triggered this. the background have worked fine before.
no overheating issue. in fact, this device always feels cooler.
I've always used this charger, my whole family uses it without any issue but now the problem just started happening to me. and even with me the problem is not constant. I just charged up to 50% without any problem. there is one thing left to try. that is, I should try to restart in safe mode and try charging in that mode. if that works fine then it's definitely an app, otherwise the issue may be bigger.
