The official version of iOS 17 is expected to be launched next week on September 19. For many iPhone users, they may want to upgrade as soon as possible, but if you are someone who pays great attention to battery life, it is recommended to take it slow first. Because according to the actual measurement of the latest iOS 17 RC version, compared with the iOS 16.6.1 version, the battery life has dropped significantly after the upgrade, especially the newer iPhone, the more serious the regression.
Please hold off on updating when the official version of iOS 17 is launched next week. The battery life test results of iOS 17 RC should dissatisfy many people.
The iOS 17 RC version can basically be regarded as the official version. Unless there are any major problems, there may be other versions. Therefore, it is of great reference value to observe the performance of the official version through it. Earlier, the foreign YouTube channel iAppleBytes released actual test videos of the iOS 17 RC version. The results showed that the battery life of every iPhone has become worse, especially the iPhone 13, which is more than an hour shorter. This feeling will be very obvious.
The testing process for the iOS 17 RC version this time is the same as in the past. First adjust the brightness to 25%, turn off automatic brightness adjustment, and then check whether the health of each battery is above 85%.
The tested iPhone models include iPhone SE2020, iPhone XR, iPhone 11, iPhone 12 and iPhone 13. The battery health is basically above 90%, and iPhone SE2020 is 86%:
Also use Geekbench to test the battery mode of the software. Charge all iPhones to 100% and start running, and then see how long they can last:
Not surprisingly, the first two models ran out of battery first. The iPhone SE2020 ran for 3 hours and 24 minutes, and the iPhone XR ran for 4 hours and 14 minutes:
The iPhone 11 and iPhone 12 both lasted about 5 hours and 30 minutes, while the iPhone 13 lasted 6 hours and 51 minutes:
If you just look at the time, you may not feel anything, and you may even feel that the battery life is not bad, but in fact the test results are much different from those of iOS 16.6.1. The following is iOS 16.6.1:
iPhone SE2020 – 3 hours 36 minutes iPhone XR – 5 hours 09 minutes iPhone 11 – 5 hours 52 minutes iPhone 12 – 6 hours 29 minutes iPhone 13 – 8 hours 09 minutes
Therefore, the battery life of all 5 iPhone models has become worse, especially the newer models. For example, the iPhone 13 has lost 1 hour and 18 minutes, the iPhone 12 has lost 50 minutes, the iPhone 11 has lost 27 minutes, and the iPhone XR has lost 27 minutes. 54 minutes is quite a difference.
The battery scores are also different, with a huge regression:
Therefore, when the official version of iOS 17 is launched next Tuesday, it is recommended to wait and see if any disasters are reported, and do not rush to update immediately. iAppleBytes should also release the official version of the battery life test in a short time. After reading It’s not too late to decide after the results.
