Battery Use

2011-11-22, 23:30 PM

I have a US A1 which does not have cellular capabilities, only WIFI. Under Settings>About Tablet>Battery use, the greatest use  right now is Cell standby (77%). Tapping on Cell standby I am told that the "Time without a signal is 100% and get the advice "Switch to airplane mode to save power in areas with no cell coverage". If I do this WiFi is also turned off. This is a serious bug as my battery is being drained by cellular hardware that is not used..

Yeah, we are seeing that. Mine is going back for WiFi issues, but same data on battery usage showing. Someone said to go into airplane mode, then "reclick" the WiFi buttone. I have not done a comparison on that.

Does not seem to make a difference.

It did for me... once you are fully recharged, the cell service item will go away.

So you leave it in airplane mode permanently with WiFi on?

Either put it in airplane mode, or hack it and disable the phone and telephone provider APKs. This is Android version 2.3, and was not designed for tablets.

I see the Phone.apk but do not see a TelephonyProvider.apk.

 

Do you have this on your tablet?

I haven't bothered to look since my tablet has good enough battery for my needs. Sorry.
