What Apple didn’t tell you about the iPhone 4s

Apple made a big deal during the presentation about how talk time is longer with the new iPhone 4s. However what they didn’t mention is that web browsing and standby time (according to their own statistics) are reduced!

Video playbackUp to 10 hoursUp to 10 hours

Not exactly a scandal, but I was really hoping for across the board enhanced battery life from the iPhone 4s. Both the processors of the current iPhone 4 (A4) and the newer iPhone 4S (A5) use a 45 nanometer process and perhaps if Apple move to a 32 nanometer or smaller process in their next chip we’ll see efficiency gains up front as a line one item on the next iPhone’s keynote (WWDC July?).
