Ok, I also have same battery issues and this is what happened last time:
100% charged and I went to bed. Just pressed power once for standby mode
Woke up in the morning and it said low battery, please connect power
Came home for lunch and it was totally dead
Tried pushing the power and it started the tablet...and its now 70% charged, without me doing anything
So there is some issue with battery info and by powering off and on it seems to correct, but quite annoying

I bought 3 of these tablets and only one did I change firmware on. The other 2 has no battery issues with the stock firmware and the info is following in tablet:
4.1.1
3.0.8
smp preempt fri sep
rk30_android4.1.1-sdk-1.0
rksdk-eng 4.1.1 jr003H eng.root.20120923.101756
By the way has anyone tried the app battery calibrator? It is supposed to delete a system file and place a new one after charging the tablet to 100% to configure this system file correctly. After that you drain battery and then charge to 100%. I am currently at 40% so cannot confirm this "hack" yet

First I thought this really worked because before it got stuck at 97% no matter how long it was plugged in. After this hack it went all the way up to 100%. But after coming back after lunch I get the same low battery notice. But when restarting the power goes back again. Will try 1.01 firmware now

To help with the battery draining quickly in standby, I installed an app called DS Battery saver. Supposedly it puts the tablet into a deeper sleep, waking it up periodically based on your preferences. I've only had it for a couple of days, but i left it in standby for about 9 hours last night and only lost about 12 percent battery vs about 60 percent without it, so i think it is helping.
