While every smartphone gets slower as its ages down the line, Apple have always been blamed for slowing its devices through cumulative software updates. Though it might not be as simple as that as according to a Reddit user it might be related to a hardware problem. That can be resolved by simply replacing the device with a new battery.
A Reddit user name TeckFire faces the similar slow down issues on his 64GB iPhone 6s smartphone. According to him his iPhone 6s started slowing down after going through multiple update. According to him ‘’ My iPhone 6S has been very slow these past few weeks, and even after updating multiple times, it was still slow. Couldn’t figure out why, but just thought that iOS 11 was still awful to me. Then I used my brother’s iPhone 6 Plus and his was… faster than mine? This is when I knew something was wrong. So, I did some research, and decided to replace my battery. Wear level was somewhere around 20% on my old battery. I did a Geekbench score, and found I was getting 1466 Single and 2512 Multi. This did not change whether I had low power mode on or off. After changing my battery, I did another test to check if it was just a placebo. Nope. 2526 Single and 4456 Multi’’.
If you recall the Apple iPhone 6s users were also facing a random shutdown issue. That was then fixed with a software update. Though Apple might have done a few things to make that happen. Where it’s possible that Apple had to adjust the clock speeds of the iPhone according to the battery. So that the phone won’t pull in too much power to avoid being shutting down.
Whatever the case maybe future iPhone owners can now fix their slow performing phones by just changing the battery. Which would not only improve the battery life but the performance of the phone as well.
