Hey all, My girlfriend has an iPhone 5. The first few days she used it, she saw huge difference between her iPhone 4S and iPhone 5 in terms of battery life. Now, she says and I've noticed this myself when I use her phone that her drains pretty queckly. For example, one minute it's at 68% and the next couple minuteis it goes down to about 54% or so. The iPhone used to last about a day or so before needed to charged. Now, it doesn't even last about 6 hours before needing a charge. She doesn't run that much apps and she closes a lot of them when she's done. She doesn't have wifi, location service, or Bluetooth on at all times. I've shown her how to turn those off when she's sure she's not gonna need them. Any other tips on what could be causing this.
