hi, my battery of my Galaxy Tab T311 is not charging, the charge is really slow and it gets stuck somewhere between 20-30%, i've charged the tab for a whole night but the charging process stays the same. I'm using Slimkat rom 4.4.4
i've re-flashed it, wiped everything still no help.

Hello guys
I had my Note II (N7100) for over a year now. The battery was fantastic till like last week. I used to go from this ROM to that ROM a lot, but always went back to my rooted stock (4.1.2) and I went to 4.3 once and after realizing that it is draining my battery, I recovered.
Last week I installed DN4 and also changed my kernel and bootloader, it booted but the battery had issues. I realized that the battery isn't calibrated. So I googled and found that using *#0228# would help to calibrate the battery.
I did that but I decided I want my good old rom back. So after recovering, I re did the *#0228# again.
Then I realized the battery life has dropped to 4 hours with my normal usage (it was about a day before) and that crazy things happen on about 20% or less. Like the phone asks for sim card, or that it would turn it self off at 18% etc. This happened once at 60% as well.
And then it will stay off unless I charge it for a few seconds while off and then boot it up.
I have also realized, when charging off, it shows an empty battery, while my recovery or android itself shows 90+%.
I tried to change my kernel, no luck and I'm back to the back up before going to dn4 in first place.
Any ideas what I should do?
So I changed the batteries, and now I have my old life time back.
But still it shows an empty battery whenever I charge while the phone is off. Any ideas guys?
Hey everyone! For some odd reason every time I charge my Tab S, when I charge it up to 97 percent, 1 minute later it would jump to 100%?! But I still get 8+ hours screen on time after unplugging it so I know its not the battery. Could it be the battery meter being uncalibrated or unstable charging voltages? Im using the Samsung charger that came with my device and I own the Galaxy tab s 10.5 WiFi. I am also running cm11 and this problem happens even on stock two ROM. Would love to hear your feedback on this. Thanks!

yes sammy 4.4.2 devices have sucky battery calibration
just calibrate it. I happens when using the device while charging. Next time it does that wait for it to shut down then turn it on, do not charge yet until the device has 1% or cannot be turned on. Good luck
Hi. I have galaxy tab s 8.4 lte version. It bootloops non-stop, but ince I connect the charger, bootloop stops and it works normally. I can do the usual stuff I do with my tablet. Once I disocnnect the charger, bootloop starts again. I tried doing factory reset and wiping cache and those sis jot resolve my concern. I brought it to Samsung Service Center and they want me to pay Php12,000 ($300). I don't wanna pay that amount of money because it's like buying a new tablet. Please help! I feel devastated because I use my tablet to read ebooks. Thank you!
Have you tried the standard Android battery re-calibrate.
For anybody reading this going from 100% when charger is connected and straight to 99% when you disconnect it, is supposedly NORMAL from what i have read about how the battery gauge works.

Hi Folks,
I have bought a new original battery for my Galaxy S2 SGH T989 since my old battery is not holding the charge and discharges quickly. The new battery came with 40% charge. I have inserted the battery, turned off the phone and plugged into the charger whole night to make it ready for use. At morning, I am surprised to see the charge animation logo is showing as it is charging from 40%. I turned the phone on and saw the battery percentage as 41.
I tried to charge with the phone turned ON. And I noticed that it just charges for 2 to 3 seconds and then stops charging. The charging animation of the battery runs for 2 to 3 seconds and then stops. Have tried with different chargers, cables, power banks but it behaves the same. At times it charges for sometime like 15 to 20 mins and then stops. Somehow I managed to charge it to 90% but its really tiring to always keep an eye on it.
I am not facing this issue with my old battery. The old battery charges well with all the cables and chargers I have. I am not sure where could be the problem. Please help.
Hi,
Bit long story, I know, but I'll have rooted Galaxy tab 3 8.0 and the problem for few weeks has been that the battery has gone mad.
So, when battery dies and tablet shutdown and I try to start again after a while there's no enough juice to even start fully or if it starts it shows 1% and shutdown immediately. That's as it should be I guess.
BUT, if I plug into charger when batt is empty and it has shutdown it suddenly shows very random percentages like 12%, 45%, 52%. 75% etc totally random even it should be something like 0%-1%.
If I then fully start it android shows that same big percentage but batt won't last a minute if I plug off the charging cord.
If I then plug in the charger again when it has shutdown it may show totally different percentage than last time but also dies as soon as I plug off the charger.
First time it could be like 12% but immediately after shutdown suddenly 71% etc.
Also when I try to fully charge battery it often jumps from around 70%-80% to 100% and while discharging it can suddenly drop from around 45% to 1%.
I have tried many things like wiping batt stats and fully charge from empty to full with power off/on, restart after full and charge again, leaved it screen on to slowly kill the batt etc.
So is that batt just badly worn after many years or is that "battery information file etc" somehow messed up that it can still be fixed/calibrated?
Ouh, and my current rom is AICP 12.1 (Nougat 7.1.1) if it matters.
Thanks
Hello
I have a P601 that charges very slowly. It almost takes an hour for %10.
Today I decided to test charging when tablet is off, strangely I saw that its %71 charged but when I turn it on is shows %48 charged.
Tablet is not rooted and its on Lollipop.
Thanks
