I charged my battery when it was at about 49% overnight with the wall charger and unplugged it when it was full. I thought it was completely off. I booted it up today and I get the battery specs in the picture below. Does anyone know what happened? I have the screen brightness pretty low too.
The up time of the tablet is 1:17:53 but the screen time on says 2h 56m 22s. Any help would be appreciated.

I'm brand new to android really and I could have also read this all wrong. If so tell me so, lol. Thanks.

Hello,
yesterday i played around with the nexus awhile and before i went to sleep it showed me a battery percentage of about 40 percent. today i wanted to turn on the device but it was completely discharged. it seems that the battery indicator doesn't behave correctly on my device. is there somebody else who has the same problem?
EDIT:
Sorry, I missed this thread: http://forum.xda-developers.com/showthread.php?t=2015728
Hello all,
As the title says, I'm having this weird issue with the tablet. The tablet loses a significant amount of battery charge when the device is turned off completely. For example I would charge it to 100% at night then switch it off completely, not just to sleep, I would wake up to about 60% battery left. I'm seriously confused what to do. I have taken this tablet 3 times now to the service centre. They even changed the battery for me but the problem persists.
I've attached a screenshot of the battery stats example. I've turned the device off then when I wake up a few hours after, it was only 57% left.
If the device is on /sleep mode, the battery actually drained normally.
Any help would be appreciate it, otherwise I would have to let this tablet go.:
I recently purchased a used S4 through Swappa from XDA user @disasp6. When the phone arrived, the battery was fully discharged. I let my wife use the phone a couple of days while hers was being repaired, and she experienced the battery running completely down and needing a recharge before the end of the day after being 100% in the morning. I then turned the phone off and put it aside for over a week and when I tried to turn it on, the battery was dead.
I tried a test, charging the battery to 100% and pulling the battery out of the phone for 24 hours. The battery retained it's charge. It did lose just a little bit of charge in a 24 hour period, but I was able to top it off with about 10 minutes of charging. I then left it in the phone for 24 hours with the phone turned off, and at the end of 24 hours the battery was fully discharged.
I've never seen a problem like this. Any phone I have ever owned has retained it's full charge when turned off. The phone is running safestrap with Goldfinger 9.0 XXUGNK4. It seems to be running normally. I haven't seen any issues with the phone firmware or its operation in the limited time I have been using it.
Does anyone have any idea what the cause of this could be, or how to troubleshoot the issue?

I'd say first thing to do is wipe and start from stock. See if that fixes anything.

I flashed back to stock NJ4, rooted and installed Better Battery Stats. I fully charged the phone and left it unplugged over night. After 8 hours of total inactivity, the battery had discharged from 100% to 60%, and Bettery Battery Stats indicated that the phone was in Deep Sleep 100% of the time since unplugged. There were 0% partial wakelocks of any kind. In my thinking, this verifies that the issue is hardware related. Does anyone have any thoughts on this?
I would think idle drain with 100% Deep Sleep should produce somewhere around 0.5% per hour drain, and certainly less than 1%. I'm not familiar with the S IV so I'm not sure the exact number. Can anyone verify this?
Hey all
I've noticed something of late with my OP6T. When I charge it to 100% and take it off the charger, it drops ~5% very quickly seemingly without any wakelocks/alarms that cause it. Does anyone else experience this? Is there something I can do about this or is the battery just on it's way out? It's a little strange as the device is only 1yr old. I bought it around 9 Nov.
Here are some of the screens from BBS attached. As you can see it doesn't look out of the ordinary.
Another strange thing is that once it reaches around ~95% then it will start to act as normal, so it takes MUCH longer to go from 95 downwards.
What's going on here?
Other things tried:
- root and run battery calibrate
- factory flash fastboot images
- use custom kernel
All show the same issue so far. This did not happen at all until recently. Any help would be appreciated!
UPDATE: I let the battery drain completely and had the phone self-power off, then powered it up a couple more times until the "Battery too low, charge before use" sign started coming up. Once that happened, I plugged the phone into a slow charger, turned it on and left it to charge. I plugged it out when I went to bed (at 100%) and it seems to be all good now. Woke up 6 hours later with the phone at 98%.
Just in case anyone else is having the issue, give that a try.

Battery percentage is a estimate. Discharging it fully and charging it only makes the estimate a bit more precise. I remember on my old phone that it could drop 40 percent in 15 minutes and when you put the device away in your pocket it could go up about 5 percent.
Hi, Let me elaborate.
My Mi A1 is running Derpfest AOSiP (The latest update). I just now noticed that when my phone is off, it shows a different battery Percentage but when I turn it on, it shows more (All while charging of course). I also noticed that 71% while off is 100% while on. I also once decided to stress my battery and see if it would go past 71% but it wouldn't because it's at it maximum capacity but the phone would keep charging. What's wrong with my phone? This looks really dangerous, charging my phone while off.
EDIT: I know the battery is fine because I just changed it a few days ago. And also nothing wrong with my charger. Could this be a kernel thing?
Thank you for taking your time reading, any help is greatly appreciated
It's probably the battery has fake capacity, download AccuBattery and use your phone as normal to determine the real battery capacity.
