Is mobile data enabled? That can cane battery life...I'm starting to wonder about LTE though...My carrier (O2) here in the UK isn't rolling it out until next year, so I can't make a comparison...It's a distinct possibility though.


I'm getting excellent battery stamina with good old 3G only...I'm not saying LTE is the culprit here, just maybe

WHAT GIVES?! I have done nothing on this phone except text, a phone call, and check email!
That's not unusual. I've been getting ***** battery lid. Did you restore from a backup or setup as new? Many have suggested setting up as new is a better way. I'm trying it.

That is better than what I have gotten. If I use it for like 1hour straight, it drops really fast... I get between 4-5hours on my phone. I would really like to hit the 7-9 hours I am seeing on this forum from some users.
I am restoring the phone in iTunes, then will set up as new and restore from iCloud. Apparently this has helping some people. Let me try and see the usage tomorrow.

Had similar concerns...

Took my girlfriends phone into Apple for Genius Bar appointment. Genius took the phone and ran some diagnostics and said "It's charging erratically" and swapped the phone. Hopefully the new one holds up better.

Asked him to run the diagnostic on mine, but they were running behind so made another appointment for tomorrow. Guess we'll see how it goes. Also curious to see what they will do since I used Unlock_Fusion to get mine unlocked if a swap is required.

Both phones were set up as new on Sep 21st when we got them as to avoid this type of issue (had it before with my 4).

I notice you are at one bar signal strength. You don't have a very strong signal and that will drain your battery in a hurry. I get 1 to 2 at best at home, so I always switch over to wifi at home, and battery life is much better.

It was hard to tell, but they had a drawer full of them. I asked if it was a refurb, he said they were so new they didn't have refurbs available yet. The box didn't look thick enough like the retail box though, so I imagine it was some kind of replacement inventory.

Your signal could be the answer, with only one bar the phone has to work harder to maintain signal.

In one of my classes last year I did nothing but use my phone (still got a A) and I would go from 80% to 0% in less than two hours because of how bad my signal was.

Ive been able to go a day and a half without charging. I suggest you try these things.

Turn off auto brightness and set the brightness level at about 25%-33%

Even though you dont have LTE in your area, your phone may still be searching for it. Go into your settings and disable the LTE even if you dont have it in your area.

Turn off iCloud backups, this can take up alot of data and battery over time

Turn off push settings in email and make it Manuel instead

Also run your battery down to 0% and charge it over-night to 100%

These should all help in some way or another...

That's strange. I'm on my phone all day long (web browsing, game playing, texting) on both WiFi and LTE and I usually have 45% or more left at the end of the day when I go to plug it in for the night.

most likely weak signal causing the phone to constantly have to search and hold the connection.

Mine was at 100% 12 hours ago and now is 98% , this is just overnight.

I always turn cellular data off, because if I am at home, Wifi is on anyway.

I will test mine out today using it for texts, browsing etc and see what battery life I get.
