Is this battery usage normal?

[Guest Farquea]

I have just put GSF on my phone and been pretty disappointed when i woke up this morning to see my battery has drained 15% in 7.5 hours. Now i have read lots of threads of battery drain, done recalibration etc but just wondered if the following is normal - as soon as i used it this morning i went into battery usage in settings and 50% was taken up by "Power Idle" and 50% by "Mobile Standby". Now if im a sleep and not using the phone surely it should be closer to 100% for one (whichever is sleeping)? i charged it to 100% then unplugged it and pressed the power button straight away and went to bed.

I have noticed that spare parts battery usage doesnt work on GSF so can anyone reccommend what apps i can use to try and discover what has caused this drain as previously on SS i would get no more than 10% drain overnights which i wasn't impressed with and installed GSF to hopefully fix and improve on.

For the record i have wifi turned off data and 3g left on but i'm using JuiceDefender free version in Balanced mode. I was considering buying it to put it into airplane mode on schedule during the night but still thought without this i shouldnt be having 15% drain. I have sync disabled and i think the only apps using data would have been Words With Friends which checks every hour and assume it still does this while the phone is sleeping and JuiceDefender balanced mode in active?

So yes, i'm not asking for someone to solve my problems but to suggest the tools available for me to hopefully get to the bottom of it myself would be greatly appreciated!
