Apple iPhone 5 battery life with iOS 7 beta 1 – the iPhone 5 lost 3% of its battery after the first 3 hours, although this had been without any use and only on standby. 12 hours later and overnight after a sleep, we noticed the iPhone 5 at 86% battery and again this was mainly on standby. Now let us take a look at the iPhone 4S over the same period and again being on standby.
Apple iPhone 4S battery life also with iOS 7 beta installed – within just 3 hours the iPhone 4S running iOS 7 beta lost 15% of its total battery life, and this is a much faster drain than experienced with iOS 6 or on an iPhone 5 with iOS 7 beta. 12 hours later and under the same circumstances as with the iPhone 5, the 4S battery hit 1% left and this is with the device being on standby overnight.
It is also worth noting that we fully charged both iPhones again and after using the iPhone 4S for just web browsing, the battery drained 5% in only 10 minutes. This certainly highlights major problems with iOS 7 beta on the iPhone 4S, but it could just be a bad install and this has happened before with iOS 6.
We have two usage screenshots below taken from the iPhone 5 and 4S running iOS 7 beta 1. These were taken before the above test and give a little insight into the differences between the two generations of iPhone running the same software. The first is the iPhone 5 and the battery percentage can be seen at the top right, and the second screenshot shows the iPhone 4S again with iOS 7 beta and with only 1% battery life left.
Finding out if this is an iOS 7 beta 1 bug or a bad install – following the above tests we have wiped the iPhone 4S and installed iOS 7 beta 1 from scratch to see if battery life improves after a fresh install. We will update this article with our findings after the next test and this will reveal if restoring the iPhone 4S content and settings on iOS 7 beta caused the battery problems, or if in fact it’s an issue with iOS 7 beta 1 even on a fresh install.
It is clear that the iPhone 5 vs. 4S battery life is far from equal in our initial tests, but keep connected to Phones Review as we update you within the next 24 hours with more details from our review. We want to find out if this is just a bad iPhone 4S install and how to fix the battery drain on iOS 7 beta 1.
Update: After a fresh install of iOS 7 beta 1 on the iPhone 4S, we used the phone for just web browsing for an hour and noticed a dramatic improvement on a clean install. This isn’t ideal for most users, so we will now restore the old backup and see if things are better after restoring from a fresh install.
