Updating To Newer iOS Version Will Drain More Battery Of Your iPhone

Apple is constantly releasing new iOS updates every year, with many features and performance improvements. However, there is a problem with these new updates, which is that battery life will be significantly reduced. A recent practice test of iAppleBytes proved that.

Four new iPhone 6S devices have been replaced with new batteries, to ensure the fairest and most accurate result. These 4 iPhone 6S have 4 different versions of iOS installed, including the latest iOS 12.3 Beta 1, official iOS 12.2, iOS 11.4.1 and finally iOS 10.3.3.

These iPhone 6S were then tested by running the same YouTube video until the battery ran out.

As a result, the iPhone 6S is installed with iOS 12.3 Beta 1 running out of battery quickly, lasting more than 10 hours. Two iPhone 6S installed iOS 11.4.1 and iOS 12.2 have nearly equal time, staying at over 10 hours and 30 minutes. Meanwhile, the iPhone 6S with iOS 11.4.1 can be used for about 7 minutes longer.

Finally, the last phone installed with iOS 10.3.3 won this test, with 11 hours and 41 minutes. This is a surprising result because battery life is always a factor of interest to users and developers after every new iOS update.

This result reinforces a conspiracy theory, that new operating system updates will make the old device slower and force users to spend money to upgrade. Apple has not yet commented, but there are many other factors affecting the battery life of the iPhone, while new updates also often come with more features and better performance improvements.

It is not a good reason to rely on this result to justify our continued use of older iPhones and install previous iOS versions. Over time, any device will slow down eventually along with its battery life. Therefore you should still upgrade to a new device if possible.
