Okay, Im now ready to make a statement about abttery life.
-Last night on airplane mode - 3%.
-Normal night (with pretty much all kernels, with +-2%) is 8% (norm for froyo, had a bit smaller drop on eclair).
-Usage with latest G kernel (browsing internet mostly, either opera or stock). Just crazy. I can go through 40% of battery in just a bit more than hour. What I am not sure is that it is hardcore kernel to blame - same is on other kernels (even oc, or uv).
So its either some traits that latest kernels (YAOK, OC and this) share, or something to do with ROM, or something to do with my configuration.
Configuration. ext4X3, all hardcore tweaks (all!), Docs ROM, Launcherpro with twitter 15min, facebook 3hours, beatigul widgets 30 min-wakeup.
Services/apps: flip2silent (never had issues), nobars (never had issues), powerstrip (never had issues), ocassionaly systempanel (but without monitoring in background).
