iPhone 5s iOS8.4 no service issues
I recently upgraded my iPhone 5s to OS8.4. The next day (yesterday) my phone was in and out of service between "No Service" and one bar. I can use the apps and send/receive texts when there is just the one bar, but I can't make/receive calls at any time (even when I do have a bar of service). Also, my battery power is fading really quickly. Like from 98% to 48% in 5 hours. I don't use anything excessive on my phone and keep the brightness low. I haven't changed any settings or anything like that so I know it's not me who is doing something wrong. I'm just wondering if there is a fix for this or if other people have been having similar issues. I'm not sure if it's due to the update or not. If I need to take it in to an Apple Store, I will - I just want to try everything in my power first.
Thanks!
