Hum Posted September 10, 2016 Share Posted September 10, 2016 Could the battery be going bad ? I've had this tablet about 2 years. I charge it up to 100% -- which used to last about 6 hours. Now when I use it away from home, after say, 2 hours, I get a battery-low warning -- plug device in. But the strange thing is, when I get home and plug in the charger, the screen says anywhere from 30 to 70% charge left. Any ideas ? Link to comment Share on other sites More sharing options...
Hum Posted September 11, 2016 Author Share Posted September 11, 2016 I added a battery charge management app. It seemed to help a little. But after using the tablet for about 3 hours, it said 10% power left. Plugged it in at home -- read 56%. Something in the OS software must be screwy. Maybe I will back-up files and do a Factory reset. Link to comment Share on other sites More sharing options...
The Evil Overlord Posted September 11, 2016 Share Posted September 11, 2016 I'm thinking battery abuse, try draining it completely, and then a couple of power cycles other than that, probably needs a battery change what I do find interesting however, is that I have the 2010 version of that tablet and it'll go weeks between charging, (but that's very light use and reading) Hum and Victor Rambo 2 Share Link to comment Share on other sites More sharing options...

HoochieMamma Posted September 11, 2016 Share Posted September 11, 2016 If you have done a full reset/made sure its not an app using CPU or making the tablet sleep correctly then I would just replace it. http://www.ebay.com/itm/Genuine-SP3676B1A-1S2P-Battery-for-Samsung-Galaxy-Tab-10-1-P7510-P7500-N8000-/152225116098?hash=item237152efc2:g:OxIAAOSwFV9XxvEy https://www.ifixit.com/Guide/Samsung+Galaxy+Tab+10.1+Battery+Replacement/18432 Never ever let your battery go to 0% it destroys Li-Ion batteries doing so. Let them get to minimum 35% and then recharge them to 100% and then disconnect them. Link to comment Share on other sites More sharing options...

I hear everyone say this, but to be honest I'm not even sure what this means, I've always fully discharged my lithium batteries (By this I mean the device will turn off from lack of power <I understand that there is still power within the cell and it's not completely 0%> sometimes I won't even bother charging the device until the next morning, and devices like my note 10.1, or my 2012 moto g still run fine) If it's a guideline, then so be it.

Hum Posted September 11, 2016 Author Share Posted September 11, 2016 I think 10% is about the lowest it ever gets. I mildly panic and turn it off. For the first couple of years, I could rely on my tablet to go 6 hours. I don't understand why the 2 different readings, saying 10% when it really is 56%, or whatever.

The Evil Overlord Posted September 11, 2016 Share Posted September 11, 2016 Try leaving it idle after it's been charged, just so you can gauge how long it takes to discharge? Link to comment Share on other sites More sharing options...

Hum Posted September 11, 2016 Author Share Posted September 11, 2016 If I would do a Factory reset, would my Android tablet return to the Kit-kat version ? Lollipop screwed up so many things. Link to comment Share on other sites More sharing options...
The Evil Overlord Posted September 11, 2016 Share Posted September 11, 2016 (edited) No, it'll be whatever the current operating system version it is running at the time as far as I can tell it basically wipes all user data (not on the sd card if applicable) and restores the installed os Then you'll have to re download all your apps (not a problem as play store keeps a record) and restore your personalised settings Link to comment Share on other sites More sharing options...
