Many iPhone, iPad, and iPod touch users had reported that their batteries were being drained after they updated their devices to the iOS 12.2.
To verify whether the new iOS updates had anything to do with it, iAppleBytes decided to test it out by adding new batteries to four iPhone 6S devices that would allow all devices to have the same amount of battery capacity.
They were running on the latest version of the iOS 12.3 Beta 1, one of them were running on the iOS 12.2 which released last week, the third one was running on an older version of the iOS 11.4.1 while the fourth device was running on the oldest iOS version 10.3.3.
iOS Battery Test Results
- iPhone with the iOS 12.3 Beta 1 lasted for 10 hours.
- iPhone with the iOS 11.4 lasted for 10 hours and 30 minutes.
- iPhone with the iOS 12.2 lasted for 10 hours and 37 minutes, which appears to be similar to the iOS 11.4.
- iPhone with the iOS 10.3.3 lasted for 11 hours and 41 minutes.
Based on the results above, it shows that the newer the iOS version, the more battery is being used. Clearly, the iOS 10.3.3 iPhone wins. Here is the battery testing video made by iAppleBytes:
This surely indicates that it might be Apple’s plan to drain battery for older iPhones. This would make iPhone users wanting to upgrade to a newer version of the iPhone.
It’s actually the developer’s job to test out how much battery each new iOS version uses. Therefore, we believe this shouldn’t be a surprise to Apple.
Although, running the older iOS version may not be much of a choice for users as all security patches and new features always in the newest iOS versions. Therefore, it’s best to keep your iPhone updated unless you are really in need of that extra hour battery on the iOS 10.3.
