Only part of in which will be true: Older iPhones with aged batteries *are* more sluggish than fresh phones — yet Apple claims the idea’s because they’re trying to avoid forced, unexpected shutdowns, not because they want you to upgrade.
Basically, iPhones use lithium-ion batteries, which decay over time.
After 500 charge cycles, the iPhone battery will be designed to retain only 80% of its original capacity. So depending on use, you may start to see your iPhone’s battery life dwindle after a year or so.
As the battery degrades, the idea can no longer handle demanding tasks, like processor-intensive games as well as apps.
So, for iPhone 6, 6S, SE, as well as 7, Apple recently released a feature in which throttles — or slows down — the iPhone’s processor when the idea’s running on a decayed battery. in which will be to prevent your iPhone through malfunctioning as well as shutting down.
In a statement to BuzzFeed News, Apple said:
“Our goal will be to deliver the best experience for customers, which includes overall performance as well as prolonging the life of their devices. 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 within the device unexpectedly shutting down to protect its electronic components.
Last year we released a feature for iPhone 6, iPhone 6s as well as iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device through unexpectedly shutting down during these conditions. We’ve right now extended in which feature to iPhone 7 with iOS 11.2, as well as plan to add support for additional products within the future.”
In any case, the idea’s frustrating when your iPhone will be slow! The best fix? Replacing your battery.
Getting a fresh battery (which costs $79 out of warranty through Apple or less having a third-party, nonauthorized service provider) will likely improve your iPhone’s performance significantly. the idea’s a lot cheaper than getting a brand-fresh phone!
Look what a battery replacement did because of in which guy!
If you’re wondering if your older iPhone will be experiencing battery decay, you can use Battery Life or Geekbench 4 ($1) to run battery benchmark tests.
Apple Support can also run a remote test in which will check your iPhone’s overall battery health.
The battery page in Settings may also show a notification when the idea detects your battery could need replacing.
