Recently, Apple released iOS 172The official version of the update has brought a number of new features such as the handwriting app, the return of custom prompts, and the translation function, and also fixed many bugs, and many users have chosen to upgrade. However, for some relatively good device users, iOS 17 is more concerned2. How about the battery life, after all, the old equipment is upgraded to a new system, and the battery life is prone to decline.
Exactly iOS 172. How is the battery life?Well-known blogger iApplebytes has brought the latest iOS 172The official version of the battery life test, come and see if your iPhone upgrades to the new system, whether the battery life has become longer or shorter.
First, the test model.
As in previous tests, there are still only 5 models participating in the endurance test this time, including models from A12 to A15 chips, mainly including:
iphone se2
iphone xr
iphone 11
iphone 12
iphone 13
The iPhone 14 and 15 series models are still absent, which is a bit of a pity.
2. Unified settings.
In order to reduce errors, all models tested with uniform settings, including upgrading to iOS 172 Official version, the screen brightness is uniformly adjusted to 25, the automatic brightness adjustment function is turned off, the automatic brightness adjustment function is uniformly fully charged, all background apps are cleared and restarted, and the volume is set to the same level, etc.
The test tool, using the Geekbenk 4 battery benchmark test, uses a high-intensity battery life test (similar to the heavy use state of running a large game for a long time), so the power of each model of iPhone from 100% to continuous exhaustion, most of the persistence time is not long, which is quite different from our daily light use, and the purpose of the battery life test is mainly to show the battery life changes of different iOS versions.
3. Test results.
The test** process is not shown here, let's take a look at the 5 iPhones that participated in the test on iOS 172 Heavy operation under the official version, the final battery life performance is as follows:
iPhone SE2: 3 hours 30 minutes.
iPhone XR: 5 hours 05 minutes.
iPhone 11: 4 hours 55 minutes.
iPhone 12: 6 hours 00 minutes.
iPhone 13: 7 hours 27 minutes.
Fourth, the comparison and summary.
Finally, let's combine the previous test data of iApplebytes to comprehensively compare iOS 160 – ios 17.2 The results of each iPhone model are shown in the chart below.
First of all, let's take a look at iOS 172 vs. the previous iOS 171.2 What are the changes in the battery life of the 5 iPhone models compared to the official version? Through the comparison of data, it is not difficult to see:
iPhone SE 2 battery life has been reduced by 3 minutes;
iPhone XR battery life has been reduced by 10 minutes
iPhone 11 battery life has been increased by 4 minutes;
iPhone 12 battery life increased by 7 minutes;
iPhone 13 battery life has been reduced by 9 minutes.
Overall, iOS 172 Compared with the previous official version, of the 5 models participating in the test, 3 have decreased their battery life, and 2 have increased their battery life, but the fluctuation range is not large, and on the whole, there are ups and downs, and there is little change. If you take an earlier iOS 170、ios 17.0.3 As a comparison, the battery life of the old version will be better, so it will be a better choice for the old model to stay in these two versions.
It is worth mentioning that the battery life test is missing iPhone14 and iPhone15, two relatively new and important models, and those who hold these two devices can upgrade to iOS 17 if they have already upgraded to iOS172 official version, you can leave a message to say whether your iPhone battery life has gotten better or worse.
