A1: Unusual battery depletion is almost always caused by people choosing to “Restore from backup” instead of “Setup as new iPhone” when iTunes asks you. This isn’t caused by either the jailbreak or the unlock, but it’s a common 3.0 snafu. The fix is to just re-run the official 3.0 restore and choose “Setup as new” this time. Your music and apps and all that will still be synced, but you’ll get rid of any conflicting wifi, bluetooth, or carrier settings.
A2: Disable/off these functions and use it whenever you need.
1) Push Notification
2) Location Services
3) EDGE
4) 3G
5) Wifi
6) Brightness set to half or less and off auto brightness
7) Mail - fetch new data set to off and Push Off
8) Kill all background apps by using Processes via SBSettings for jailbreak iPhones. For non jailbreak iPhones, use
4. Force Quit Program 9) Disable SSH if you install earlier for jailbreak iPhones.
Take note: Charge your iPhone for atleast 4 hrs + (USB cable or 3 pin plug). Then shutdown and boot your iPhone. This will give you longer lasting batt as in the spoiler. Do drain your battery once a month whenever possible.
