That's 10 hours at that usage, give or take, and right around what I'm seeing, 10% per hour of actual usage as an ebook, about 2-5% per hour if it's just sitting there connected, and about 15-20%/hour with heavy surfing or game playing.

2-5% per hour just sitting there connected? Are you talking about standby here (i.e. screen locked, phone not doing anything), or am I misunderstanding? Because in those circumstances I've observed much less than 1% per hour drain. I observed a drop of 3-4% overnight (9 hours). That works out to about 9-13 days, which is what I would expect for a phone in standby when the battery is as huge as this. Are you guys seeing less than this for standby?

standby maybe ok, but as soon you start doing anything, surfing the web or doing anything else , battery drain is fast, you can loose up to 15% in one hour, so is a poor performance somehow...

Maybe its because the speed of the processor or some firmware bugs ...

Sounds like your Batterystats are way off, try getting into CWM and wipe the batterystats...

Strange... I did yesterday a trip with BT and navigation on for about 4 hrs driving, 2 calls etc. At arrival on destiny I still had 87% left ...



edit : I'm using latest Sygic from Market as navi

I'm running Juice Defender and I've UV the CPU with SetCPU to -75mV on all CPU settings (OC to 1.3Ghz - min set 100Mhz).

I did a little test with an overnight charge to 100% and I 'just about' got 36hrs out of it - that was a couple of hours playing games (Trial Extreme 2 and Super Stickman golf ), several hours browsing including Tweetdeck refreshing, texting and 3G (or rather "H") usage.
There was an element of standby for several hours not least over the second night (approx. 7.5 hrs).

Not bad at all I think - gave me confidence that my JD and SetCPU profiles are doing what I want.
I normally charge every night anyway which gives me plenty of Juice for the days ahead.
