    Hi All,

    I'm hoping someone can give me some advice with my battery. I got an iPhone 6 in early December, so almost exactly 2 months ago. It's been working great. I'm not a power user, so I've been getting about 2.5 days of use off a full charge. Then last week the battery just starting draining way faster. Now I get about 10 hours of standby and 2 hours of use before it completely dies. When compared to my wife's iPhone 6, after 10 hours of standby and 2 hours of use, she still has 75% of her battery left.

    Here's what I've tried or have ruled out:

    - I don't think it's the LTE as I live in Los Angeles and have a solid signal most places I go, and those habits didn't change last week.
    - I don't use push, background app updates, location services or anything else that hogs battery, except for Waze, that I mention below.
    - I tried deleting my email thats on Exchange, I heard that can help.
    - I let it drain to shutdown then charged it uninterrupted to full charge, a few times.
    - I did a restore to new phone from iTunes, but none of this has helped.
    - I called apple and was told that the long battery life I was getting was abnormal, and I should settle for this new shorter battery life.

    Here's what's weird. This is the third phone this has happened to. It happened in November to my iPhone 5, which had great battery life for over 2 years, then the same symptoms developed. When the Genius bar couldn't fix it, I traded it in for an iPhone 6, but the same thing started happening the first week I had that phone, so I returned it for the one I have, which has been great for 2 months, until last week.

    I only have 3 theories left.

    I use iCloud and it's the first thing I log into after a restore. Is it possible that something in there is draining the battery in the background, maybe my podcast subscriptions or something like that?

    I started using the app Waze a while ago, which I know uses a lot of battery, even in the background. Even though I don't even have it on my phone now, could it have fried the battery?

    I have a Griffin car charger, which I use with an apple cable. Could it have fried the battery?

    Sorry to write so much. Any advice or guidance would be appreciated.

    Thanks so much.

    Make sure you don't have background app refresh on.. and same with location services. I'm not sure what could be causing the drain.. have you tried to do a restore? Just make sure you back up before you do, but sometimes it helps.

    Thanks for your reply, heyyitssusan. I have tried all of those things, including the restore. I was really hoping that one would do the trick.

    did you restore from a previous backup?
    Have you tried restoring the phone and not setting up from your previous backup?

    I did not restore from backup. I restored it to be a new phone. So currently it has no apps on it, or music of anything like that. When I log into iCloud it pulls all my email, contacts, calendars, etc from the cloud. I suppose I could run a test where I restore and do not log into iCloud, to see if that helps?
