Apple recently released their new iOS 12.3 software, we previously saw some speed test videos and now we have a new battery life test video for the handset.
In the video we get to see the new iOS 12.3 go up against the previous iOS 12.2 on the iPhone 6 and iPhone 6S handsets. The battery life tests were run using Geekbench 4.
As we can see from the video om the iPhone 6 the battery latest for 2 hours and 24 minutes with iOS 12.2. There was a small improvement in the battery life on the device with the new iOS 12.3 release.
On the iPhone 6s the iOS 12.2 lasted for 3 hours and 26 minutes and on the iOS 12.3 test it lastest for 3 hours and 20 minutes, so a small decrease on that test.
It looks like the new iOS 12.3 software does not provide any major improvement in battery life over the previous software.
