iPhone 4s with iOS 7.0.2 Battery Drains FAST!

Basics from the manual are restart, reset, restore from backup, restore as new device. Have you tried any of these besides complaining and being upset?

Go to Settings>General>Background App Refresh and switch it OFF! 😀

Hope I helped!

I upgraded my iPhone 4, wife's 4s, and my 3rd gen iPad to IOS 7 when it was released and had no dramas. A couple of days ago I installed the 7.0.2 update and now the battery drains insanely fast on all. Yesterday I noticed my iPad seemed to drain quickly. Today my wife's 4s went from 100% to 3% in about 3 hours with light usage. This afternoon, my 4 went from 100% to shutdown in 4.5 hours with practically no usage and a reset just prior to removing it from the charger. All I did with it was just turn it on every couple of hours to see what the battery level was. I also noticed that although the phone was just sitting on my desk it was noticeably warm. I have already done all the suggested battery saving tips - turning off background app refresh etc. Prior to 7.0.2 it has never discharged this quickly even with heavy use.

I am facing the same issue. I upgraded my 4S and 5 to 7.0.2, and with I am seeing a huge drain in battery life. The 4S is as bad as OP, however, the 5 holds up better. I have tried all the tricks with background app refresh to location services to app updates. Nothing helped.

Is there a way to downgrade to 7.0.1?

Upgraded my 4s to 7.0.2 two days ago and today I am experiencing the same. I have disabled everything and my battery won't last more than 3 hrs on standby...what to do now? One interesting thing, I did a hard reset (on/off and home button for 10 seconds until apple icon appears) my battery was at 63% after it rebooted my battery was at 88%. what gives with this?

I've pretty much proved to myself that this is a bug in 7.0.2. Since my post a few days ago I have:

Done a full restore of my iPhone with 7.0.2 - problem still persisted - draining battery at approx 23%/hour with no use, and with all the battery saving tips applied (no push notifications, no background updating etc).

Restored iPhone with 7.0 - battery drain dropped to approx 5%/hour with no use and battery saving tips applied. With push notifications & background updating turned back on, battery drain increased to approx 12%/hour which is high, but still significantly better than 7.0.2.

I would recomend everyone who is having this problem with 7.0.2 to lodge a bug report with Apple - www.apple.com/feedback - hopefully if enough of us lodge the bug report, Apple will listen and release an update.

As for downgrading, unfortunately we cannot downgrade to 6.x anymore, but you can downgrade to 7.0. It is a matter of downloading the appropriate firmware. Firmware's are available here - http://www.icj.me/ios - although that site lists 6.x, they will no longer work, so get the 7.0. That site redirects you to Apple's server for the appropriate ROM, so they are legitimate. Before you install it, you have to turn "Find My iPhone" off by going to Settings | Privacy | Location Services | Find iPhone. The installation seems to turn it back on when done, but you should probably check. Once the firmware has downloaded, you can install it on your device by going to iTunes, and holding down the option key while clicking Restore. This is on Mac - on Windows I assume you would press Alt (but if that doesn't work, try Ctl or Shift). If you have pressed the right button on your keyboard, a file browser window will appear, allowing you to choose the firmware that you just downloaded.

Once installation is complete, iTunes will tell you that there is an update available for your iPhone, just click "Later" everytime the warning appears.

I should add that restoring to the earlier OS took several hours on my iPhone, while iTunes restored the backup then re-synched my apps. Probably something to run overnight.

Thanks. I did try clean install of 7.0 last night, but my problem doesn't seem to have gone away. I did notice that it automatically downloaded 7.0.2 but I haven't clicked Install Now, so it hasn't been installed.

Anxiously waiting for the next release.

I did a full restore to 7.0.2 again today, fully charged at 10am this morning it is now at 37% (7pm). With very minimal use. This is better than before but still not like it was before installing 7.0.2. Will file bug report as you advised. Hope they fix this soon 😟

Until yesterday, I had the same battery drain issue with my iphone4S running iOS7.0.2: 1% per 2-3 minutes, and clearly about twice the battery usage than with iOS6.1.3.

Then I did three things last night that have apparently improved things for the better:

1. rebooted phone twice

2. disabled and re-enabled iMessage

3. charged iPhone at 40% for like 8 hours.

All prior suggestions like disabling PArallax, disabling Background refresh, Bluetooth etc, didn't improve battery life at all.

I took the phone off the charger at about 7am this morning; now at 5pm, after 36 minutes usage and 10 hours standby, the battery percentage is still at 87%.

Don't ask which of those three things, or even one of them, did the trick ... so far. Will monitor things.

I have the same problem after install iso 7.0.2 my battery cannot last for 5 hours. I am using iphone 5 . This morning buying a new ipone5S thinking that the old phone have battery problem. I think the new one also have some problem, although it may last a little bit longer

My iPhone (5) has even more battery life than before after the update.

There are some settings that will solve this problem:

• Disable the parallax effect that gives the home screen that 3D look by going to Settings > General > Accessibility > Reduce Motion.
• Turn off the background app refresh for at least some of your apps by going to Settings > General > Background App Refresh.
• Turn off AirDrop by swiping up from the bottom of the screen and selecting the toggle in the Control Center.
• Go to Settings > Notification Center and toggle off any apps that you don’t want to include.

Having same issue. No battery problems before ios7 now can't make it past noon without plugging in at work. Tried everything apple suggested and still draining like a leaky pipe. What ****** me off are all the snotty *** people saying you have to turn off these settings and turn of that setting. Didn't we by iPhones so we could use these options. Why do I have to turn off all my phones options for it to last until lunch. My son laughs at me because I bought him a galaxy 4 and it has many more options and a much bigger clearer screen than iPhone and lasts all day and night with heavy teen usage. If update doesn't come quick I may forgo the i5 and go the way of samsung. They seam to be on the right track. Apple just seams to be getting worse with every update.
