Following the release of iOS 26.4 and 18.7.6, some may be wondering how the updates affect battery life drain and performance. Now we know, with a new video putting both of the updates through their paces.
Posted to YouTube by iAppleBytes, the new video takes the updates through both performance and battery tests on a number of different iPhones.

By running the tests on multiple devices, it’s hoped that more people will be able to compare the results with their own devices.
We won’t spoil the results for you, instead we recommend checking the video out to see how your particular iPhone fared.
However, while you could use these tests to get an idea of what you can expect from iOS 26.4 and 18.7.6 in terms of performance and battery life, we wouldn’t let them delay your update plans. Both of these updates included vital security fixes, and for that reason, we strongly suggest installing them as soon as possible.
This update adds additional features to the iPhone and is likely to be one of the last major updates before Apple unveils iOS 27 at its WWDC event in June. The software will then undergo a months-long beta process before being released to the public this fall.
