    Pretty much what he title says I have noticed that when I reboot my phone the battery % drops significantly for instance today I was at 88% then rebooted and it came back up it was reading 74%. I have had the issue with both regular and extended battries. FYI I am rooted and running das BAMF 1.4 I saw this mentioned inside another thread and was wondering if this was something that a lot if users are experiencing and wether it happens on non rooted phones as well

    It happens on unrooted phones as well. I'm not convinced the battery meter even knows what percentage of the battery is left. I've seen mine stuck at 20% for longer than it took to get from full to 20%.

    A reboot does use some additional power, though and I'm thinking it's a combination of poor metering and the extra power needed for the reboot.

    Yeah, if this doesn't prove to you that the battery meter reading is a load of <cough> I don't know what will. Ever since I got this phone on the release date, every time you boot, you lose about 10-15% battery. Now that I'm rooted with roms claiming to have a more accurate battery reading meter - I still have around 5-8% loss when I reboot. Just enjoy the phone and charge it when you can.

    Like jdk2 said - it's incredibly inaccurate. This is my experience too - the battery will drain in like crazy but then last 10+ hours at 30% or 40%.
