Opening small theater: Apple's "power bank" mode is on?
Ladies and gentlemen, do you sometimes feel that your iPhone is not like a mobile phone, but more like a portable power bank? The power is consumed faster than the heat of the circle of friends? Don't worry, Apple has just released the iOS 17.2.1 official version update, which claims to fix the bug that the battery drains too quickly. But then again, is this update a "power guardian" or a "power black hole"? Let's take a look at the "truth" of the battery life test.
Endurance test: @iAppleBytes's lab is back open
Experiment Preparation: All for the sake of justice
Under the leadership of our old friend @iAppleBytes, all five iPhone models (SE 2, XR, 11, 12, 13) in the same WiFi environment, the screen brightness is uniformly adjusted to 25%, and the automatic brightness adjustment is turned off, everything is ready to give the most objective battery life.
Test Results: A picture is worth a thousand words
| Models | iOS 17.1.2 续航 | iOS 17.2.1 续航 | Changing circumstances |
| iPhone SE 2 | 3 hours and 32 minutes | 3 hours and 28 minutes | Slightly decreased |
| iPhone XR | 4 hours and 45 minutes | 4 hours and 26 minutes | Noticeably lowered |
| iPhone 11 | 4 hours and 20 minutes | 4 hours and 36 minutes | A slight boost |
| iPhone 12 | 5 hours and 15 minutes | 5 hours 07 minutes | Slightly decreased |
| iPhone 13 | 7 hours and 45 minutes | 7 hours and 30 minutes | Slightly decreased |
From the table, we can see that except for the iPhone 11, which has slightly improved the battery life, the other models have decreased to varying degrees. Does that mean we're going to start saving some electricity?
How is iOS 17.2.1?
Compared with the early version of iOS 17, Apple seems to have done a lot of homework in 17.2.1, at least the battery life has not fallen off a "cliff". For older models that can't be upgraded to iOS 17, iOS 16.7.4 is also a good choice, and stability and security are always good.
iOS 17.2.1：稳定性优化成主旋律
With the arrival of iOS 17.2.1, it seems that we can expect a more stable iOS 17. After experiencing a series of problems, Apple is obviously actively checking and filling in the gaps to optimize the user experience. So, dear fans, what do you think of iOS 17? Have you already felt Apple's "care"? Welcome to share your feelings in the comment area.
