What battery drain issues? I have no battery drain issue on 7.0.4. In fact, my battery life on 7.0.4 is better than it has ever been on any iPhone or version that I have owned. It's very rare that a battery drain problem is caused by a specific version. There is only one that I recall in the past 6 1/2 years where the actual version caused battery drain. In almost all cases battery drain problems are related to a misbehaving app.

I have 210 apps on my iPhone. Interactive games are the heaviest users of energy. If you are getting 5 usage hours playing games you are doing well. Facebook is way up there also, even when you are not using it, because it processes notifications and updates in background.


Turning off Background App Refresh does not affect the built in apps. They run whenever they want.

You can start by deleting the Facebook app, and see if that resolves the problem. But first determine how bad the problem is. Note the current battery level, put the phone to sleep for several hours, and check the battery level again. If it is much lower then you have some app draining it. If it is close to the same level (within a couple of %) then you don't have a battery problem you are just a heavy user.


This is common wisdom: http://osxdaily.com/2013/09/19/ios-7-battery-life-fix/


I don't agree with some of it, but it's a good place to start.

I use Cellular Data, but YES the signal is sometimes WEAK and as you said maybe the battery drains due to the same.


But, usually when the iPhone is idle (means, when I don't use it) the battery drains slowly by 1 or 2%, is it cause of the Notification Bar??


I also use lot of WhatsApp for chatting, is that another reason for Battery Drain??

Anything that uses cellular data (including Whatsapp, facebook, interactive games, etc) will use more energy with a weak signal. The phone must increase its output power to maintain a connection. To give you the idea of the range, a 5 bar signal requires only a 60 milliwatt signal, but 1 bar can require as much as 500 milliwatts. 9 times as much energy.


If you are watching it drain this means the screen is on, which consumes power. Press the Sleep button, and check a couple of hours later without using the phone. If it drops 1% or 2% in that time it's probably working right. If it drops 20% there's a problem, which could be notifications. Try turning off all notifications and see how it affects battery life. Then turn them on a couple at a time until you find which one is use the power.

Do you also own an iphone and an iPad? I have struggled with all solutions to fast depleting battery on iphone 4s (and on the ipad) since installing ios7. I sync via icloud to my ipad and noticed the problem stopped if I powered off the ipad for a day! ios7 must have set up some cycle that drained both devices. Now I have set the ipad to manual (not push) on icloud and diary sync and battery life is back to normal for a whole week it can last 48 hours with light use- no longer have to keep shutting down all apps and turning off bluetooth and wifi to get through a day! Any one else found the same solution?

Hi Folks,


iPhone & iPad2 battery drain issue SOLVED!!!!!


I had a serious battery drain problem on THREE devices using different iOS .... it was a simple fix and had certain characteristics that you may be able to relate to ......

Devices; 16GB iPhone 4 with IOS6

16GB iPhone 4S with iOS7.06

32G iPad2 with iOS7.04


On or about Feb. 28th all three devices started to drain the battery like crazy losing about 20%/hour on the iPhones and 10%/hour on the iPad2 .... After messing around with settings, browsing forums and looking at what was common between the three devices I concluded the problem was with a single Microsoft Outlook/Live/Hotmail email account in the iOS native mail app .... I deleted the email account on all three devices (along with other unrelated Microsoft accounts on each device) and did a hard reboot (hold HOME and top LOCK button simultaniously for about 10 seconds until the apple logo appeared).


I then re-created the common Microsoft Outlook/Live/Hotmail account on all three devices in the iOS native mail app ...... SUCCESS! Now all three devices are behaving normaly with respect to battery drain ......


Hopefully this will be useful to others in this thread ..........
