I just opened my replacement phone last night; I haven't sent my old one back yet. The past two weeks have yielded awful battery life. Yes, I have location services on, bluetooth, wifi, et cetera. But I've never turned these things off and something has changed dramatically, even after a restore as new. I've had this phone now for about 12 hours. At 0530, I took it off the charger at 100%. This is my usage as of this morning and I'm at 81%. If it's worth noting, I watched it go from 84 to 83 to 82 in a matter of 30 seconds. Can using a third party lightning cable cause this even if I'm using the apple brick? This does not seem normal. First world problems, I get it, but this is really frustrating me.
