With the new debut of iOS 17, iPhone users have both expectations and worries, among which battery life is undoubtedly the focus of many fans. Especially those old iPhone users who have a model from a few years ago are particularly sensitive to the battery performance after the system update. Today, we're going to share a test from overseas, taking you through the game: how does the iPhone 14, 13, 12, 11, XR, SE 3 and SE 2 last under iOS 17
First, let's talk about the details of testing. The UP master completed the iOS 16 battery life test on the first day, then immediately upgraded all devices to iOS 17, and conducted the exact same test on the second day. The iPhones were tested under the same conditions: battery status, chip configuration, and the same Wi-Fi and cellular networks, and Wi-Fi remained connected throughout the test. To be fair, the screen brightness of all devices was set to the same level as possible and remained the same between rounds. When fully charged, these iPhones are ready for the challenge.
The first item of the test was **Stream**, which lasted a full hour. Immediately after, we had an hour of mobile safari browsing, simulating daily online behavior. Then, it's a one-hour social*** browsing test to see how much the battery drains when scrolling**. Finally, the TikTok rolling test also lasted for an hour, testing the endurance of each iPhone on popular short** apps.
