Battery Drainage in Standby Mode

AppleFanatic10 said:

Has anyone else noticed that their battery drains significantly when it's not connected to the charger but its not being used either? I've noticed that when I unplug my iPhone then go to sleep my battery will sometimes go from 100 to 70. Anyone else have this problem?

I did for a while at first. It was from a back up of my 4s. My battery would lose at least 10-15 percent each night. Finally restored as a new phone and never had the problem anymore.

How strong is your LTE or 3G signal at home. If it is weak, it can drain the battery. I always leave wifi on because LTE signal is pretty weak at home.

Leaving WiFi on is much easier on battery than off.

Not an issue here.

my phone does the same thing, 8-10% overnight.

I get all 5 bars and my 3G/LTE are pretty good. I do notice that my phone constantly switches from wifi to LTE when it's locked, and I'm not sure why it does that. If anyone knows how to fix this please tell me lol. Maybe that's the problem?

You know I haven't tested that really since I moved into my new place with my two other friends. I've noticed that the connection isn't that great and the internet will randomly drop out (but show connected on all my devices/computers) throughout the day. One of the reasons I don't leave wifi on all the time in my house. My LTE is much better and more reliable anyway. But I've either always had my phone plugged in at night or didn't pay attention at all to the battery stats. I'll check it out soon.

My iphone 5 went from 99% to 96% last night with about 45 minutes of usage before I went to bed. Definitely make a genius appointment and get a replacement.

I did that a couple weeks ago. Restored my iPhone 5 to a new phone, thinking that it would resolve a bug I recently had. I've turned most of iCloud off, just left the contacts and find my iPhone on, put auto-lock to 1 minute. Bluetooth, and Personal Hotspot are off. And the brightness is not even close to 50%. I'm not sure what the problem could be.

No, you should have great battery life even with those things turned on. You need to get a replacement. I leave BT, GPS/location, iCloud on and brightness way up and the battery kicks ass.
