As I mentioned in my review of the iPhone 5, battery life was certainly a concern during the first several days of use. The battery drained at an alarming rate of 1% every 3-4 minutes with just basic web browsing (3G on, LTE off), and during the first 2 days, my phone would lose 20-30% overnight while on standby. With my iPhone 4, it would drain no more than 1 or 2% throughout the night. Not surprisingly, after searching online for similar cases, I soon found that many iPhone 5 users were also experiencing poor battery performance. Furthermore, those who upgraded to iOS 6 with their iPhone 3GS/4/4S were also finding that they weren’t getting nearly as much juice out of their phones. Not wanting to exchange my iPhone 5 a second time unless I really had to (i.e defective battery), I tried a number of “fixes” in hopes of rectifying the issue. Thankfully, they seem to be working and I’m starting to see some improvements.
The iPhone 5 not only got a facelift by growing to 4″, but it’s internals have been upgraded as well. Utilizing the all new A6 chip, it’s even smaller and faster. 2x faster then the iPhone 4S’s A5X chip for CPU and graphics. Apple claims that the iPhone 5 will launch the Pages app 2.1x faster and load the music app with songs 1.9x snappier.
