I know the longevity of smartphone batteries aren't great, but within this last week mine has declined noticeably. I can't think that I've added any new apps that would be the cause. I've had this phone since July 2011 and I'm running 2.3.4 on my rooted SGS2, I use Battery Monitor Widget and SetCPU (which seems to have helped in the past). The only thing I've noticed but don't fully understand despite searching online is the high percentage of time the phone is 'awake' and whether that is a good or bad thing (I would assume it's bad to be awake if the phone is sitting idle). I have attached some screenshots to illustrate this...
I'm seriously considering the genuine Samsung 2000mAH battery upgrade. Any thoughts on a cause or can anyone enlighten me about what being 'awake' means?
Any help appreciated. Lisa
