Hello friends, using Lenovo ThinkPad slate tablet and having lot of problems with battery, such it hardly remains for six hours if I am suing Wi-Fi. It is not happening for all the time it was fine with new unit which is having complete first charge before using. I do feel that reason of poor battery performance is due to 10% battery is wasted on "Cell standby” which is having a 100% time without any signal. I would believe that it might be consequence of an old udev enabling WWAN when there is no SIM card in it, but I do not know much about Android. Does anyone is getting this problem with Ice Cream Sandwich? Please help me out with it and what I should do to make it use for longer time? Thank you.
