9 hours to charge and then discharge in less than an hour? Other times it will charge in an hour and discharge even quicker.
Tab is rooted and I've tried clearing battery stats and the fully charge, off for an hour, discharge to 50% and off for five hours with no consistent results.
Sometimes it will charge in the normal time (2-3 hours) and discharge normally (8-12 hours) but that is the exception.

Using 4.4, aren't you? Does it happen on Gingerbread, too? All 4.0+ ROMs on the P1000 have shown battery issues on some devices. Also you can try to recalibrate the battery:
1. fully discharge the Tab until it doesn't turn on any more;
2. charge it while switched off (when on 100%, leave it connected for at least 2 hours);
3. with the cable connected, turn on the Tab and leave it for five minutes;
4. unplug it and repeat the cycle for 2-3 times.

Strange battery drain.

Well, some time ago (Like 3 days) i've installed Pure Vainilla v4. So, when i let my charger plugged in the night and in midnight i turn a bit the screen. The battery starts to drain very fast :$
Without any use and the stats go crazy .-. Any ideas?

The strange thing is that, when i wake up in the morning and i disconnect the charger, before i do it, the battery icon shows 100 and the fully charged notification is there but when i disconnect the charger, the battery drops to 40 in the stats, i plugged the charger again so now it is charging normally. But, i'm pretty sure it will happen again.
Edit: I plugged it and it seemed to be working fine but still discharging D:

[Q] Nook HD+ doesn't turn on, just charging indicator

Hi,
My Nook HD+ shut down after battery drained, now after hours of charging all I see is this:

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

}
What should I do to run the OS? is it bricked? Anything possible to make it work again?
This happens to mine every now and then.
To fix, try:
1) make sure you use the Nook transformer (some phone or other usb adapters may not provide sufficient current to recharge a drained battery);
2) soft reset while attached to powered Nook transformer (hold power button for 20 seconds).
To avoid in the future, never let the battery completely drain. That is where I go wrong each time, forgetting I left it in standby mode with a low charge for a couple days.
I hope this helps.

[i9305] after 100%, charging continues for 2-3h more till green LED

Hi Guys,
I have small problem with my Galaxy S 3 LTE. When charging phone it reaches 100% (2-3 hours of charging), however when it is 100% charged still red LED is showing up and status is charging for next 2 or 3 hours till green LED show up. I found topic when they advised to charge it till green LED when phone is on, unplug charger, power off phone and plug charger again till 100% (green LED). This didn't help for me.
Going across threads on forum I found some APS were I noticed that android is showing up my battery capacity is 3100 mAh. Phone is not rooted (4 months old).
Please find attached picture

What I did recently it was changing soft from 4.3 to 4.4.4.
Thank you for help and ideas how to solve it up.
Any ideas?

Is my Battery toast after 300 cycles?

I have this phone since a bit over a year. When i got it I installed the app "charge cycle counter" which counts the total of 0%-100% charge cycles. My phone has 280 so far. My battery life got worse and worse (both standby drain and sot) so i did a reset and switched to xiaomi.eu. Shortly after the reset with no apps installed the battery drain didnt get better. Im in airplane mode all the time. Do you think my battery has degraded so much already?

Did you try recalibrating battery without root?
I read on some thread that when phone shuts down with 0 battery, boot into twrp, screen brightness at maxximum, disable locking the screen.... And wait until phone shuts down. Mine stayed on for 1h45min. After the phone dies in twrp, charge it when its off to 100%. Got from not even 2h SOT to easily 4h on xiaomi.eu.

Redmi K20 Pro Air Temperature is Low

Hello Friends. I got a warning that the "Air Temperature is Low bla bla" with an indication that my battery is not normal, for example my battery is in the 80% position and it drops for a very long time, but suddenly from 80% to 70% or even below. and when I'm charging in the 50% position, but it doesn't go up as if charging doesn't come in, but instantly from 50% to 60% and keeps going up. This abnormality when I checked using Franco Kernel Manager the temperature position reached minus for example -37. And suddenly the temperature returns to normal and the battery is normal.
I think the problem is with the battery, I've replaced it 2 times with different brands but the problem doesn't go away, anyone knows the solution? I'm so dizzy, thank you.
