asked on How do I tell if it is it my battery or something else
I have a small Lenovo Pad that, until last week, would always charge to 100% and gave me very good life. Usually I only use it for a couple of hours so it goes back on charge at around 90% and stays on charge until I need it again (two or 3 times a week). Occasionally I leave it in sleep mode and forget to connect the charger so it goes totally flat. Not sure if this happened in the last week. At any rate I now find it will only charge to 60% then it says "Not Charging" but the symbol shows that it is connected to a charger and if I unplug it, the unit goes to its "running on battery" settings. If I unplug and immediately reconnect it, the unit will then keep charging for another few minutes before saying "not charging" again. And if I persevere I can get it up to 65% charge. But if I leave it alone, yet connected, it drops to below 60%. I've tried a different charger and cable but the result is the same.
It's not a very good unit (quite slow) so I don't want to spend a lot of money on a new battery unless I can be reasonably confident that the problem is the battery. Is there any way I can know with some level of confidence? The battery is not easily removable.

I have a Lenovo laptop that has been pretty much always on power for it's entire life and I haven't noticed an issue.
I spoke to someone who claims knowledge of batteries some time ago and was told that the best thing to do for max battery life is to keep it at about 30% until you need it but that's a bit impractical so I just keep it fully charged. Apparently that's not good for the battery but for me it's the only practical option.

Thanks for all your comments. I will have to resolder as I managed to get it back to 100% with a bit of perseverance. At this stage I am not ready to buy another tablet so I will have to solder. Thanks for the instructions about the battery too. I will share the points as you all taught me something
Just a bit more advice....use a good quality soldering iron.
I also used leaded solder. My experience with lead-free is sloppy solder connections.
If you're concerned with absorbing lead through your skin, use latex gloves and/or wash your hands after you are finished.

Thanks ScottCha. I may end up taking it to an expert as I am not very confident with soldering, especially micro circuits. As it turns out my DVR is in for repairs so I may ask the repairer to look at the Tablet at the same time. Thanks for your ongoing support
I am going to leave on test a little longer but I am starting to suspect it may be a loose connection inside the tablet. I've left the tablet at an angle, so I can keep an eye on it, and it's only stopped charging once. When I put a bit of torsion on the plug it started charging again and it's now up to 72%. If I can get it to close to 100% it may be the female Micro USB connector in the tablet. Not sure if that's easily repairable.
