Chinese tablet battery problems
August 3rd 2011 -
For over 6 months I’ve been a happy user of Chinese manufactured Android tablet, HaiPad M701-R based on Telechips TCC8902 core.
I was happy – but I was disappointed with one thing – battery life. I had to turn off the device completely very often (using built in hardware switch) – because the device had broken sleep mechanism, and was draining battery like crazy (even on upgraded 2.3 firmware).
I got around 6hr standby time max (with WiFi radio off) – and this was when device was not used at all – even less than my MSI Wind U100 with new 7.2Ah battery running with WiFi on (this may not be the best comparison, but I hope you understand the reason for my disappointment).
Few day ago, while I was browsing slatedroid.com forum, I found a guide that mentioned recalibrating battery as remedy for short battery life – and to my surprise, it worked incredibly well.
From 6hr standby time, I managed to get 17hr, half of that time with WiFi radio on. I have not measured run time while browsing/watching movies (I don’t think I will be a lot better than before calibration), but now I know that I don’t have to turn my tablet off when I don’t use it.
