I've tried just about every trick in the book to try to improve my battery life. I can no longer get my 5s to last longer than 7 hours usage. I've restored phone as new, tried not fetching email, taken off location services. Seems nothing has worked. At one point on my iphone 5 I used to get around 9 hours but that was on ios6. Not sure it could be the OS. Anyways just wondering if anybody has any tips that has worked. Thanks
