I'd take it into the Apple Store to ask for a replacement, but I don't want to seem like a whiner, so I want to make sure it's not normal (in other words, a problematic battery). I used my iPhone 3GS while on a trip to NYC last week. It was on the battery for 10 hours, but was on standby almost the whole time (I only took it out to look at the map for a minute, and to take a couple of photos, that's it). When I came back home that night, I noticed the battery is close to the red zone. The battery almost depleted by about 10 hours of standby? My original iPhone could stay in standby for 3 days before depleting the battery. Isn't the new iPhone batteries supposed to be better? I just wanted to check if this is normal, or I should take it into the Apple Store and ask for a replacement?
