iPhone 4S Battery drains quickly with iOS 8

My iPhone 4S battery drains very quickly after the iOS 8 update. Below are the settings of my iPhone 4S

1 Location Services - OFF

2.Background App Refresh - OFF

3.Brightness - Auto-Brightness

4.Bluetooth - OFF

5.Wi-Fi - OFF

6.3G - OFF

7.Mail Push Notifications - Manual

8.Mobile Data - ON

Almost all the sites suggest to check the Battery Usage, new feature in iOS 8 but that always shows the Phone, Home & Lock

Screen and other apps which I use daily. Whatever the app I open in a day that makes the battery drain fast and that is hat listed in

Battery Usage.

After around 2 hours of usage daily, battery comes below 10% and the phone is switched off. I don't have problem with slower

response from iOS 8 in 4S but I did not know that it would kill my battery this much fast. iOS 8.0.2 also did not address solution to

this problem. Very frustrated 😟

Hi.

I have 3 Iphone 4s phones in use, one on me, two as test phones whit different setup. Have updated my phones with the latest update 8.1.2.

My issue with draining battery was fixed by the update 8.1.1, and the phone can be used "normally" a day or 1,5 as expected and compared to the changes to Ios 7. This means that there is still some more power needed to run IOS 8 than did with IOS 7, but then there is also many details that work better and many of theese have to do with networking, which is of most power draining functions.

Then because of some changes in how the IOS 8 work and is configured by default, one has to decide which details in different areas of the operations are needed or can be swithed of. I.we done so and the difference in battery extend is significant. Switch of everything you do not need, or wan´t to have up and running. some of which are listed earlyer in this thread.

All of the listed solutions do not help if your phone have some physical problems of broken parts.

Happy IOSing !
