My phone has been pissing battery life down the drain in the last month or so.

It was a real fucking trooper before lasting for a day or two depending on usage. Now I've had to turn off the GPS and even if the display is off it can barely do 10 hours before conking out. Should I actually want to use it that number reduces dranatically.

It was fully charged when I left my car at 8:30 this morning (had it on charge), I played a game for about 10 minutes on the bus to Uni and another 20 minutes or so during my lunch break. I've had to break my charger out just now at 60% or so.

40% loss with 20 minutes usage in 7 hours, ugh.
