This is weird!
The battery on my iPhone 3G seems to get stuck on 100%, if i go to usage it sais
"Time since last full charge"
USAGE = 2 Hours, 24 Minutes
STANDBY= 1Day, 20 Hours
and the battery is at 100%
THAT! is impossible!, i will continue using it to see what happens!
I even download a app from the appstore that shows the battery (it sucks, HHEHEHEHEHEH) and it shows 100% too...
You guys may not be far off with the suggestions of problems with the battery percentage meter. I had both the SBSettings battery percentage hack and the plist hack installed. When I disabled the SBSettings hack, the battery percentage jumped from 87% to 92% immediately, without respring (the toggle in the Settings app was turned to on). So it looks like those who turned on the percentage via SBSettings are reporting a lower battery percentage than those who turned it on with the plist edit. It may be that the SBSettings hack is pulling the value from another area than the plist hack, making it look like the battery is draining faster than it really is. Something to look into.
i was having lots of problems with battery drain..my iphone would barely make it a day of light use. this was jailbroken 3.0 with sbsettings installed.
i restored to 3.0, then jailbroke to 3.0 but did not install sbsettings. my battery is better than ever now. started the day around 11 (took my phone off the charger.) i ended the day at 2 am with 60% battery. this was after 30 min of phone, an hour of 3g internet surfing, an hour of edge internet, and a LOT of texting.
TO EVERYONE WITH BATTERY ISSUES, I SUGGEST YOU RESTORE, REJAILBREAK, AND DO NOT INSTALL SBSETTINGS. I AM ALMOST POSITIVE YOUR BATTERY LIFE WILL INCREASE TENFOLD.
