Q: iPhone 5 battery draining very fast

it all depends on how you used your phone.eg.1 hour of gaming vs 1hour of phone calls,both use the battery at different rates.my iphone 5 battery is fantastic.since last friday i have charged my phone 2.5 times.that includes 3 hours of internet radio per day,gaming 1 hour per day.listening to music 2 hours per day and around 30 minutes of calls per day.my last count was 1 day 3hours of standby and 9 hours usage and my battery was at 63%

Whoa, that means my battery is really defective because it was 5h45 of light usage... No gaming at all. Music, Internet browsing and Facebook/Twitter... I definitely need an appointment at my Apple Store... It's a shame I'm really disappointed.

try this fix

Connect to your computer and iTunes.

Do a reset by holding the home and power button.

Right when your phone turns off, let go of the POWER only.

iTunes will then recognize and iPhone launching in recovery mode.

Restore the factory settings as prompted.

Load every thing individually from the cloud, iTunes, but don't restore from back up

and run your battery down untill it switches off,do this two or three times

I have an appointment this Saturday.  I'm extremely disappointed... this is my first iPhone and I'm really starting to regret the purchase....  I'm not sure what to do... I have 1 more week to return it.

Ok thanks I will try this tonight but tell me. How can I restore app data from the cloud without restoring from a backup?

I know that if I reconfigure my iPhone as a new one, I just have to enter my iCloud account password and it will resync Notes, Contacts, etc. but what about app data? Game saves and so on..

i dont use the cloud,i back up my data to my pc.but if the fix solves your battery problem it must be worth it.this fix has helped a lot of people.

I have had the same issues for a few days. After a few full cycle charge, battery life showed improvement! Also, the telco staff told me to switch off LTE as certain areas do not support LTE, causing the battery to drain excessively. It seemed to work for me, do give it a try. Saved for the battery issue, love the iPhone! :)

How do you back up on your PC? When I connect to my PC I don't get a "storage device" connection, just camera which is annoying. I don't think I've really used the cloud yet although my phone says it's backed up to the cloud but I can't access it from my PC because I'm XP.  I don't have a lot of data on the phone yet being it's my first iPhone.  My contacts and things are syced with gmail.  I see people say that they sync their apps to itunes but when I try to do that it looks like it's going to wipe all my Apps from my iphone. I haven't paid for any apps yet, just free ones... but I have my kindle app on there that I've sent a bunch of books to and I'd like to back up.

Can I back up these free apps using itunes or do I need to download free ones again?

If this is best suited for another thread please point me there! Sorry guys... new to all this stuff.  I appreciate any help anyone can provide me! 

The link below shows how to back your iphone up to your PC.

to back up to your pc you must first turn icloud backup off on your iphone.a message will pop up on your phone saying that data will now be backed up to your pc.all the saved data is stored within itunes.if you connect your phone to your pc it will open itunes, on the left side it will show the iphone click on this and all the iphone related info will be displayed.the windows message that appears when you first connect the phone to your pc should be ignored.it has nothing really to do with the iphone or its settings

Update from yesterday**

Ok I performed an IPhone 5 data backup using the procedure under Itunes "How to Back Up" via this link

http://support.apple.com/kb/HT1766

Next, I restored the firmware on my IPhone 5 via the following procedure http://support.apple.com/kb/HT1414

After that, I restored my previously backed up data via the "How to Restore From a Backup" section on this link

http://support.apple.com/kb/HT1766

After all that, my IPhone was 100% charged at 10:30pm, so I disconnected it and did the following:

• Made a 1 hr phone call (only drained 10% of the battery instead of the usual 20%)
• Downloaded a bunch of apps
• Checked email
• Surfed the Internet
• Put an internet radio app on "infinite play" on before going to sleep at 3:20am
• Left the internet radio app on "infinite play" until waking up at 8:00am.
• Left the internet radio app on stay on "infinite play" while showering and driving to work.
• Turned off the internet radio app around 9:30am and have not used the phone much since.
• Battery is @ 20% and its 10:18am.

Current stats are as follows:

Time since last full charge:

Usage: 11 hours, 15 minutes

Standby: 13 hours, 11 minutes

This is better than what I got when I did 2 full re-charge cycles. It seems the reloading of IOS 6 made a significant difference. Will continue to analyze and report the status tomorrow.

Also, 10:30pm to 10:18 am is NOT "24 hours, 26 minutes" (13 hrs, 11 mins + 11hrs, 15mins), so there is something odd about how the phone calculates usage and standby. Perhaps someone from Apple can clear that up?

Are you on AT&T or verizon after the restore did you tunr off LTE or wifi or 3g or you left all the settings untoched after the restore proccess ?

When I got the iPhone 5, I plugged it into the wall until it hit 100% then unplugged it and started using.  I did this about three times.  In the past with various devices from various companies using Lithium, I read that you should let it charge even after it hits 100%.

Last night was the first time I charged it overnight, and I'm experiecing a better battery performance.  I'll follow-up again after a couple of days.

Currently, I restored my phone from iTunes, and I did not restore from backup.  I copied all of my apps over, music, books, etc.  Everything is running (LTE, Wifi, Notifcations, and Locations) except for Bluetooth, which is the default if you said "Yes" to everything when setting up your phone.  Currently, I don't have my email turned on.  I will be activating Exchange later today to see if it changes the performance.  I use Exchange to Push two Gmail labels, and I get about 20-30 emails a days.

dyeylet,

I am on AT&T, and I left LTE, 3G, and WIFI on and unchanged after restoring my data and configuration from backup.
