Hi all! So after my iPhone 4S began to drain from 100% to 0% in under 10 hours without even being touched I decided to go in to Apple and get it changed. Using it would see it fully drain in under 3 hours (and that's just for texting occasionally and viewing calendars etc). Now Apple advised me that they will replace the phone (which they did for another fault) but regarding battery life they said that my backup is probably corrupt and that I would need to set it up as a new phone. I wasn't in a position to do that as I am travelling and really need all my texts etc. Today after 2 hours of very light use the phone is on 83% which to me indicates that there may be something sinister happening in my backup? Even while writing this it went down 5%. My brightness is low, SIRI is off, there's no apps in the background and I have deleted most apps too. Has anyone encountered the above bug that apple speaks of? Thanks!
