In the past week, realised that WiFi at work (using 802.1x auth) has been draining my battery like crazy.
Here are some stats I took over the past few days:
Case Connection Duration Battery left A 802.1x Wifi ~10hrs 0% B 3G ~17hrs 46% C WPA2 Wifi ~1d 11hrs 34%
In all three cases, usage was light: occasional checking of email, sms or two, short phone call etc. If anything, probably used the phone more in case B&C - played some light games.
The odd thing is this crazy battery drain has only been happening in the past week or so - used to be at 20% after ~15hours when connected to 802.1x Wifi.
Does anyone know why Enterprise/802.1x WiFi is causing significant battery drain?
