Q: iPhone 5 battery life is way worse than iPhone 4

Player8: I may try to set the Calendar to fetch, just out of curiosity. Unfortunately, when I've taken the calendar off exchange and used fetch before, for whatever reason it's led to problems like appointments being duplicated to the wrong calendars, meeting requests not registering, etc...

And btw, my model number is MD638LL.

Ive been having the same problem i restored from iP4s and still we left both my 4s which my husband now has and 5 side by side and 5 drainned a whole lot faster on standby when i use it it goes down quickly

So, I get VASTLY different usage time based on where I am at for the day...At HOME in a rural area with spotty cell coverage I get roughly 4 hours of usage.  However, at WORK in a major city, I am at 60% or so with the same usage...THIS HAPPENS REGULARLY.  Usage is texts, email and time killers (words etc) with zero streaming (netflix, pandora).

IDEAS as to why this is???

ALSO...I regularly used to use less than 500 MB of data/month with my IP4 on ATT...Im at 850MB in my first 2 weeks with IP5 and Verizon...Any idea why these two things are happening????

Player8: This morning I tried disabling the Exchange Calendar and switching it to the regular CalDAV/Gmail side... Unfortunately, there was no difference in terms of drain rate. By the time I got situated at work it had a reported usage 1hr 7mins and was at 86%. (keep in mind it once again waited 20 mins to fall 1%, then plunged).

I reinstitued exchange calendar, but set it to "Manual" in settings so it will only look for updates when I open the app.

I also set all my email to manual, and am now using the gmail app.... on the theory that, it will push me a notification but only download messages in the background when i open the app. Will report back....

There's a correlation between signal strength and battery life. Basically, the stronger the signal, the better the battery life. This has been especially apparent with LTE, evidently.

Also, LTE uses more data. Partly because of the LTE standard, and partly because of its speed users just naturally use more. I remember back when the iPad 3 introduced LTE to the Apple lineup, I read about people who blew through their 2GB caps in two weeks.

same here,lot more data usage,also i never seem to get over 3 bars of 3g,most of the time only one or two bars.or switches over to edge.now you might think this is because of a bad 3g signal but i never had these problems with my previous iphones.they always had full bars on 3g so...and lte,well apple hasnt activated lte for iphone in belgium yet.they will in a couple of weeks though.god only knows how that will drain my battery since im losing 1% per 2 minutes of usage on 3g already...i'm a moderate to heavy user and right now im up to 1GB per 1,5 week.that's just nuts,2GB used to last me a month.but F the usage,i just want better battery life,as good as or better as my previous iphone,as they promised us!

Check this out. It's an app called Onavo Extend - It routes your data traffic through the service's servers, compressing it and reducing the data load on your phone. It's similar in that respect to Opera Mini, but apparently works anytime your phone connects to the internet via cellular, regardless whether the app is open. They claim to reduce your data load to about 1/5th what it otherwise would be.

I'm skeptical anytime a single server has access to all my information... but may be worth checking out. secure data, from the looks of it, cannot be read by their servers.

I spoke to a complete stranger tonight about our iPhone 5. She has the same problem as we do. She just didn't say anything about it to apple but won't ever buy an iPhone again. Her words. So imagine how many people have this problem and just aren't saying anything but DEFINITELY won't forget how ****** of an experience this is for them and how inconvenient. Soooo it's more widespread than we think.

I've done the same here in Japan. I only know 5 people who have iPhone 5s, but 4 of them are having the same battery problems and regret getting the iPhone 5. None of them are tech savvy to the point where they'd visit these boards, but needless to say they are all dissatisfied.

Figured I give that DFU restore thing a try.... Save yourself the trouble. If anything I think it only made it worse lol

Oh Apple. Why have you forsaken us? Have we not been good? Have we not blindly followed you down every path you so carefully laid out for us?

I feel violated.

Oh waw it must be dramatic Wednesday.

DFU may have not worked for you but it has helped a number of people in other threads, so its still a potential viable solution.

guys, does 3g/LTE consume data when phone goes idle with no apps running on background? keep a look out on your data usage and see if there is any data transimission activities going on..

I had just discovered that it was consuming my data even the phone is idling.

For every interval of  2mins:

Sent 3kb

Receive 4kb

It actually stopped once 3g/LTE is off.

My battery had last me for 10mins before it drains away 1%.

The act of checking your data usage triggers the system to send data, then your antenna and screen consumes battery every time you check this page. Therefore your adding to any battery drain issue you have.

I think otherwise, because i'd done a test on an interval of 10mins as well.

Checked on data usage after letting my phone idle for 10mins

Data consumed 35kb, so if i were to break down this figure

2mins,it consumed 7kb(sent,received)

10mins will be 35kb and this is the exact figure  i got.

Hmmm other than this constant data stream do you have:

- iCloud On?

- Backup to iCloud On?

- Location Services > System Services > Options in here on?
