Last week there was a lot of talk about how iOS 7 drains down the battery of the iPhone 5 and iPhone 4S following the update? Tests did show that the Apple iPhone 4S does suffer from a big issue with battery drain.
The battery life of the iPhone 5 on the other hand was perfect, even though the battery drained down very fast on the iPhone 4S. The article that was posted did get a lot of feedback from owners of the handset who were suffering from battery drain issues. However we found a way to get around the battery drain issues.
We spent a lot of time with iOS 7 beta and we came to the conclusion that there was a lot of difference with battery life. This is something that people saw when iOS 6 came out last year.
The issue with battery drain is not with hardware. Instead it happens when installing an update, for instance iOS 6 or iOS 7 beta.
The battery drain for the Apple iPhone 5 was not as bad as with the iPhone 4S. This could have been down to luck. The issue seems to happen randomly and it depends on conditions of the installation. There is however an easy way to get around the battery drain problem.
However owners of handsets should not have to worry about this and Apple do need to do something to fix it.
Make a backup of your handset and then do a clean installation of iOS in DFU mode. To do this you would have to hold down the Sleep/Wake button while at the same time holding the Home button. You keep it pressed down until you see that you are in recovery mode, iTunes will tell you this.
Install a fresh copy of iOS 6 and then go ahead and install iOS 7 beta, then put the data back onto the handsets. You may also downgrade, providing that you backed up in iTunes.
It seems that the iPhone 4S battery drain problem is severe and it can drain down in merely hours. This can be rectified if you make a clean install. The issue seems to be when you restore the data without having made a clean installation first.
So if you are suffering from battery drain issues you can try the remedy above.
