the battery icon status not update

i use a battery indicator app. the app does show some what lower than the icon, ya. so not sure which one is correct. i know the icon can reach orange if it's too low, as a warning per se.

Only occasionally. When I'm through the working day, usually I end up with 60 or 70%. If I see it's still full, I just hard restart the phone. The icon definitely will be updated.

Also, I've been on firmware JF3 for ages, now finally Kies provided me with JM2. And maybe some people complained about the battery life to Samsung, so they decided to cheat.

JF3: 88%, first drop in battery icon, about 5 pixels wide
JM2: 79%, first drop in battery icon, about 3 pixels wide

Haha, it's just psychological, the battery is still the same, they just want to hide it better so people won't complain so much.

But as I said, even with extreme usage, at the end of the working day it's around 20-50%, still enough, so it's fine for me.
