iOS 17.2.1 Battery Life Drain Comparison On iPhone [Video Test]

Here’s iOS 17.2.1 battery life drain comparison on iPhone that you might be interested in checking out.

If you are having trouble with battery life on your iPhone and are wondering whether updating to iOS 17.2.1 will fix it or not, then you’ll be happy to know that we have got the battery life comparison test done on video courtesy of iAppleBytes.

In case you were wondering how the test was carried out, iAppleBytes explained to us in a note that:

Before the test was run, the devices were set to 25% display brightness, auto brightness was disabled, and all devices used the same settings, and were connected to the same access point.

Geekbench 4 battery scores measure the battery life of a device when running processor-intensive applications. It provides a consistent workload to the device, and generates a score by evaluating the amount of work that it is able to do while the battery is discharging and the amount of time it takes for the battery to discharge.

The battery benchmark can be run in Full Discharge mode, from 100% to 0% battery level, to provide a high level of confidence in a device’s battery performance. The battery benchmark can also be run in Partial Discharge mode, for 3 hours. If the battery benchmark is stopped after 10 minutes, by the user or by the battery reaching 0%, then the result will be saved and can be uploaded.

Battery benchmark scores gathered by any method except the Full Discharge mode provide a medium level of confidence in a device’s battery performance, and longer tests are more reliable. When comparing scores, remember that higher scores are better, and double the score indicates double the performance.

We won’t spoil the results for you, so watch the video till the end yourself to find out what’s the battery life is like on different iPhone models when running the latest iOS 17.2.1 firmware:
