Hello all and thanks in advance ..Ive seem to come across a vary stange issue i cant find any info about anywhere ..mu situation is this: i charge my tablet (polaroid s8) to %60 then it drops down to 14% and will continue to charge to 100 so essentially i have to charge it %160 but if i charge to 60 it drops to 14 and it will die after the %14 depletes HOWEVER sometimes i am able to power down after the drop and when i reboot and re plug the meter will go back up to 60 but if it goes up %1 it will drop again..wondering if its a software/hardware issue or possibly a combination..please help

i am having a quite unusual problem with the battery on my TP. it is hard to explain but i will try my best to do so. While i was casually surfing the web while on the charger i noticed that my battery started to drain ( this is the more ordinary problem that has been posted on many threads ) but this new situation is. The indicator lights and meters within the TP indicate that the battery is charging yet it still drains. I tried turning it completely off and removing the battery and then putting it back in and charge the unit for one hour. After one hour it charged to 20% which is reasonable enough for normal use, so i turn it back on and continue to use the device again the TP still indicates that the battery is charging after listening to about 7 songs i get a very low battery indicator warning (at the same time the battery indicates its charging) there is NO overheating and when the battery reaches 0% it does not die the screen just goes off and i can turn it back on and still recieve the low battery warning but what i cannot do is use data or even turn the phone radio back on. I am on the NFS 1.05 ROM, any suggestions?

Try to get a charger with an output of at least 1 A. It could be that your charger is not powerful enough to compensate for the drainage. The other thing is that WM' battery indicator flat out sucks... it is like Windows file system when it is desperately trying to tell you how much time you have left before your task is done (2 minutes jumping to 15 seconds jumping to 54 minutes jumping to 2 seconds jumping to 3 days, etc)..
Flash to another rom and see if the behavior still remains.... I doubt NFS messed up that badly with power settings, but it is always worth giving it a shot.
yea i doubt its the rom either as i was having overheating/drainage problems on stock but it wasnt anything like this
this piece of crap phone started to go worser by the minute.
First, it heats up the battery whenever i use wifi or 3g and it will also shut down. Switch battery and it will last a bit longer then still shut down.
Now, it give me this problem where a 91% charged battery would turn out to be red under 5% once insert. The battery indicator will recover slowly over time for no reason.
And i am also having trouble charging the battery by phone, if i charge the phone by usb when the phone is ON, the phone will heat up and turn off and continue to heat up for infinity until unplug.
I don't know what should i do with my x10 anymore... i am not paying out another 700 bucks CAD for a new phone in canada after just 1 years use *out of warranty*.
anyone have a fix for these? or know how do i revert back to 1.6 android?
Where is justice! Samsung should crush Sony already.
Hi everyone!
About two days ago I decided to switch off my ACER Liquid Z3 after charging the battery to 100%. Now I am not able to switch the phone on in the first instance and when I use the AC adapter to start the phone, the battery shows 1% battery.
The strange thing is that when I leave the phone on overnight (8 hours), the battery only discharges by about 2%. So, assuming the discharge is constant, after two days the battery should be at about 88%.
The other thing to note is that I did a 'update' on this phone before switching it off. But this does not tell me if the update is causing the problem because I did not do this 2-day discharge test before the 'phone update'. Also, the phone is running on Android 4.2.2.
Another interesting observation is that when the phone is plugged into a power source, the cpu locks onto the highest frequency (~1000 Mhz) and when you disconnect the power source, the cpu frequency drops and stays at around ~598Mhz
Is anyone else with this phone having the same issues? If so, has anyone resolved it? I know other phones have experienced this issue in the past.
I have not noticed this issue. Generally when on my phone drops 1% over night.
I did try to use the power scheduler to turn it off at night. It turns the phone off but does not turn it back on! Interestingly if the phone is off the alarm works, but the damn thing will not come back on when scheduled.
So in the one test I have done I have not noticed significant battery drain when the power is off. Maybe its because the battery is new. Is it any better now?

Samsung Galaxy Tab 10.1 wont start-up, after further research online i came across a few threads, which lead into the direction of draining the device residual voltage, which supposedly either usually or is supposed to take about 10 minutes.
However, i disconnected the battery from the device hours ago, (approximately 12 hours ago) and monitored the residual voltage dropping from the battery terminal on the device, not on the battery. It dropped rapidly initially then became a slow process at 0.13V, now after 12 hours, it is still sitting at 0.01V for over 5 hours now.
I am trying to drain the residual voltage so i can reconnect the battery to see if it will start-up.
It might also worth to mention that, the device was recognized in device manager on a PC under other device as APX, and i also tested the voltage output from the battery itself as its currently fully charge and seem to be outputting the correct voltage, doesn't seem to be any problem with the battery, so as it is now, i am just waiting for this 0.01V to drain so i can reconnect the battery.
Is it normal to take this long to drain? or will it ever drain to 0? or is it ok to reconnect at 0.01?
Any input or idea would be greatly appreciated.

0.01v is nothing, you can reconnect
Anyone had success with running ACC https://github.com/VR-25/acc with Zenfone 9 ? For me it does not stop charging (tried test with 3 methods). Or maybe someone uses any other stop charging method/app?
I know I can limit chaging to 80% with Asus ROM, but what I do not know, what happens next - once charging thershold is reached, does then phone get's power directly from charger not from battery? Because if it get's from battery, means phone is charging battery, every time it will drop 1%, which is bad.
According to someone in Asus forum, it indeed uses trickle charging:
Re: How battery care charging limitworks? What happens after charging will reach X%?
phone just stop pulling power from the wall, before its drop to 79% its start to charge again, u can monitor this behavior by using usb tester, its also known as trickle charging.

which means still battery life decreases. Which means it still needs some root solution, to stop charging at all :/
