also have you enabled power management for the WIFI? Have you reduced the output from 100 mw to 10 mw? How is this done? and what exactly does it mean by reducing the power of the wifi. What does this do to your web browsing experience?
immediately after the phone states it is fully charged, open xterminal and type this: lshal | grep perc it should give you the percentage. To enable power saving on the wfi follow the steps: Settings -> Internet Connections -> Connections Select your wifi connection and press Edit then : Next - > Next -> Next -> Advanced Then click on the Other tab and change WLAN transmission power to 10 mW and power saving to On (maximum) press Save - > Finish -> Done -> Save You should be ready now. In any case, make sure you disable the wifi when it is not needed I hope this helps
