iPhone 5 on 6.1.3 issue - Battery draining like crazy!

[metalcasket]

My girlfriend got an iPhone 2 days ago and for the better part of the last 2 days, her battery's been draining like hell. I'm talking going down 5% at a time in standby and crap. We've done all the usual. Location services off, Bluetooth, crap to do with push notifications, turning down the brightness, iCloud, etc...I've been using iDevices for 4 years now, I know the basics. The thing is, I've been complaining about my battery (iPhone 4) going down like hell too. Not this drastically though. Is there any known problem with 6.1.3 regarding batteries draining, and if not, what can we do about it?

This maybe a Google related calendar sync problem. I sync hotmail and icloud calendars, but I just tried to only sync icloud calendars on my iphone 4 and ipad 3 cause I am curious to see if hotmail calendar syncs cause a battery drain. But it seems if one is synching with google calendars, that can be a problem.

But makes sense just to sync calendars with icloud only. I will let you know if I see any difference on my end cause I am curious. Probably better anyway to just sync to icloud anyway for uniformity sake I figure.

This might be a bit idiotic saying this as it sounds like something you might have tried already, but how often is Mail checking for E-Mails in the background?

You can set the fetch (push) settings with emails to different intervals in the general settings. I usually just set it off and manually check, but the battery draining problem seems to be from a google calendar sync problem it seems.

When I turned 3G on it started draining the battery like crazy on my 4th gen iPhone. It went down from lasting ~2+ days to needing a daily charge.

But more relevantly, both my girlfriend and I have noticed that the battery drain had gotten FAR greater than normal in the last week or so. For both of us it only lasted about two days before it went back to normal.

I believe she's set it to Manual.

I'm having similar drainage of battery on my iphone so I just bought a battery case from Dexim and this helps me last a day.

i'm gonna say something trivial and probably not too helpful here but.. iPhones and other smartphones don't excel on the battery life. You want to have a phone with battery that lasts longer? get an old Nokia dumbphone.. you'll have a whole week between recharges.

turning off all the nice iphone features to save battery is to me pretty stupid. i mean, why get a high-end device if you just gonna cripple it? I mean, if my phone has the ability to notify me about an email the minute i receive it, why should i set it to behave differently?

Not to rub it in but you are wrong just snapped this from my Galaxy S Advance I do have a larger battery than stock but same sized so same cover, I'm also running deep sleep battery saver pro but if you look at my average life (near bottom of pic) I think you will be very suprised.



Not bad for a dual core 1ghz phone with 80gb of storage also plays GTA3 great.
