I have been having major battery issues ever since getting the 5s. I've restored a couple of times from iCloud, but it hasn't worked. Apple has said they can see a lot of crashing apps in the diagnostics report (about 30). The tech suggested I wipe it out and do a sync with iTunes instead of a restore, but apparently I would lose all of my iMessages. He said there are 3rd party apps to recover that. Anyone have experience with recovering iMessages after an iTunes sync? Any recommendations on what software to use for that? I'm assuming I would also lose any other data I have on my phone - like in Viber, Whatsapp, etc, is there any way to recover other data as well? Will I lose all of my settings this way too? I've come to depend on the iCloud backup and disappointed that I can't use it and have a stable phone.
