Why Is My iPhone Running Slower

By December 27, 2017

People are always thrilled with the annual launch of new iPhone and iOS system , what about the old iPhones? Pass into silence? Certainly not. Recently a Reddit post has blown up because it claims the reason why his iPhone running slower. All accusations are blaming Apple for not being transparent enough, and the root causes of all problems point to – iPhone battery.

According to the research made by Geekbench‘s John Poole, Apple activated the protection mechanism to ensure the aging battery life and stability after iOS upgrades.  When it detects the battery is not able to guarantee the stable operation of the new system, it will take the initiative to lower the performance, which is the primary reason why iPhone running slower after system updates.

In the very beginning Poole thought, the processor’s performance degrades along with the Lithium battery degradation. However, it was later confirmed that the performance of the processor was significantly improved after battery replacement. What’s more, within the samples of 100,000 old iPhones, the ones with system upgrade were running noticeably slower than others, the frequency of unexpected shut downs were much higher as well.  The most affected models by the slowdown are iPhone 6S in iOS 10.2 and iOS 11.2 version and iPhone 7 in iOS 11.2 version.

Not surprisingly, Apple fell into a PR crisis again. Customers suspected that Apple was trying to guide, even force users to buy the latest iPhone by making the old iPhones run slower. If it’s true, just as Poole said, Apple throttled old iPhones. However, Apple made a statement at once and insisted the unexpected results were not intentionally made by Apple. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components. However, Apple didn’t deny Poole’s research, but the statement makes sense somehow, literally Apple would not be that stupid to do the short-sight thing.

For the users who are really confused with the slower iPhone, battery replacement is recommended if you are still not willing to upgrade to a new iPhone X. If your iPhone is still under warranty, the best way is to take it to Apple Store for a replacement. If not, and luckily you have a solid background knowledge, you can take a try to fix it by following the guide on iFixit. The risk is that it will void your Apple warranty, and be sure that at least you get a branded battery for replacement.

Last year iPhone fell into battery issues, no exception for this year, is Apple able to solve the battery problem completely? 

For a short time, to provide more preferential policies for battery renewal sounds more practical for users, but it can be quite difficult because the number of users and devices involved are huge, as the original new battery supply is a problem as well, Apple has not given any response so far.
