Mine do to , I thought that was bad *sighs* coming from iphone4 so the higher the number the better?Settings > About phone > Battery > Battery use. Mine shows 86% of total usage is caused by the screen. So turning it down helps.
I think it's kind of strange... I've been using my phone quite a lot (screen turned on & surfing websites and such) with wifi on... made 2 phone calls (1 was about 15 minutes long, the other was maybe 5 minutes)
Display: 45%
Voice Calls: 35%
I find the tremendous drain from my voice calls as curious to say the least. That said, I'm getting good battery life overall.
Anyone have suggestions as to how to reduce the amount percentage wise of battery use coming from the display? I have my brightness to about half but is there another suggestion?
Also, do live wallpapers use up more of your battery? I don't have one equipped but I thought about it but want to make sure it won't affect my battery...
