I recently downloaded beta 4 OTA instead of via iTunes because I was away and didn't have my laptop, now on beta 3 my battery life was actually pretty good and then after I OTA'd beta 4, my battery life has become so bad I'm not sure what to do. My phone, (Verizon 5S) goes down 1-2% every 3-4 minutes when I'm using it. Today I decided to wipe my device and restore it back to beta 4 to see if downloading it OTA somehow corrupted it; I see a minor improvement but it's still isn't very good. Should I let the phone die and then, using a wall charger, charge it to 100%? Or should I give it more time and see what happens. Last resort I downgrade to beta 3 as I do not think my actual phone is the problem, or could it be?
