The new iPhone sucks, even more then the 4. Battery lasts for a day. If you have luck.
It's not the problem of the new phone, it's the iOS 5... Apple is fixing the problem... It seems to check the time zone all the time, which drains the battery, or that's the most common rumor :D
hmmm - i have ipad - haven't upgraded to ios 5 yet - even though there is a jailbreak already

i wonder if i upgrade, will that affect my battery ? gotta ask my friend who already upgraded
p.s. i wouldn't say new iphone sucks - neither does the 4th one - i think its absolutely brilliant, masterpiece of technology
