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.

After my phone had been on the charger all night I pulled it off the charger and noticed my battery immediately went to 98% after I unplugged it. What seemed to correct this for me was I had to turn the phone off let it fully charge then for safe measures I unplugged it and plugged it back in again till it said 100% again. After doing this my phone now fully charges and stays at 100% after I pull it off the charger.
Just thought I'd share...

The reason for this is for battery health. The phone will actually slowly leech a charge down while plugged in once it hits 100% and then recharge. The reason for this is because it's bad to leave a phone at 100% all the time. It's normal for that to happen with phones. Some phones are more accurate with displaying the proper percentage than others.
Thats odd. My phone charged to 100% yesterday and after about 30-40 minutes of rarely any usage it was still at 100
yeah it happens from time to time. But its easy to remedy.
I'm having this problem while charging my battery during the night. I'll plug the phone in when i'm in bed, and when i wake up, the phone says charging but it will be down to about 85%. i've had it show up at different levels multiple times (78%, 80%,88%, 92%, etc.) i know that the battery will charge completely and then stop charging for a little bit as to not damage the battery, but going all the way down to 78%????
any thoughts?
Today my phone ran down to 0% and it shut down. When I got home I plugged the charger in at around 5pm. Now almost 7 hours later it is still not fully charged. This has never happened before.
Do you know what could be causing it to take so long?
It is plugged in to the wall.
Thanks.
either the phone is not charging at full rate or is discharging very fast. I would try to charge with phone being off, monitor battery discharge during day especially in IDLE and take it from there. You can also download program that shows charging rate.
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.
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.
