do you have any battery programs installed?, any special Kernels? my QBW is also 1.3.3 could you try some terminal command: Code: hal-device | grep voltage.current & hal-device | grep voltage.current | awk '{printf "%4.0f",$3}' and post the results
hal-device | grep voltage.current & hal-device | grep voltage.current | awk '{printf "%4.0f",$3}'
hal-device bme | awk -F"[. ]" '$5 == "is_charging" {chrg = $7}; $5 == "percentage" {perc = $7} END if (chrg == "false") {print perc "%"} else {print "Chrg"}'
