Also just to acknowledge the troll who keeps saying Chrome is off topic. 1. All any of us care about is a fix, whether that's a setting or an app change or something else.
2. Maybe Chrome worked fine prior to 6.1.3 but now there is an incompatibility. Or perhaps Chrome updated around the same time as 6.1.3 and we are wrongly blaming 6.1.3.
The fact is, there are likely several different bugs causing battery drain. That's why not all of us can find a solution.
But my guess is that nearly all of them are caused by data. I.e data trying to send or sync and getting stuck in a loop that kills the battery. I've noticed on days that the iCloud backup didn't compete overnight, my battery does faster. Odd.
My partner didn't have Chrome installed. So I installed it last night and logged in to my account with sync on. And sure enough his battery started to drain. He doesn't have a Google account so I couldn't tell if it was specific to my account or not.
Everybody should also ensure they've turned off Push in the advanced mail section for your iCloud account.
If it were me, and none of this worked, I'd take my phone to the Apple store and request a new phone.
I really wish Apple would publically acknowledge these issues and at least tell us that they're working on a fix.
Final thought, I picked up a Mophie air juice pack case from Apple the other day, it's great and gives me almost an extra 100% charge. It adds some bulk but looks cool and makes me feel safe I.e. I don't worry about using my battery.
Don't buy via Amazon, it's full of fake Mophies, I purchased 2 prior to getting it via Apple.
I keep checking several times a day for 6.1.4 update. Anybody else do that? :D
