Your iPhone's battery doesn't just dictate how long you're able to use the device for, as it can have a surprising effect on the performance of the Apple gadget overall thanks to one very important setting.
It's one of the first thing you'll notice as your iPhone begins to age, as you'll typically find yourself having to charge your device more often, leaving you with less time on some of your favorite battery-intensive apps like TikTok or Instagram.
There are a number of tips and tricks you can employ to enhance your battery life, which include not closing your apps and changing two key power hungry settings, but sometimes the best course of action is to simply opt for a new battery altogether.
As reported by the Sun, Apple has actually implemented a system into your phone that not only lets you know when you should probably think about replacing your battery, but it also technically slows down your device in order to prolong its life.

Known as 'Performance Management', this particular feature dynamically adjusts the maximum performance of your phone's internal hardware, which has a surprisingly positive effect on the long-term health of the battery.
"As a result, the device workloads will self-balance, allowing a smoother distribution of system tasks, rather than larger, quick spikes of performance all at once," Apple explain. "In some cases you might not notice any differences in device performance."
It might seem counterintuitive to enable a setting that forcibly makes your phone 'worse', but unless you're using intensive workloads all of the time, it's not something you'll generally notice on a day-to-day basis.
Warning signs for a iPhone battery replacement
However, it can work well as a major warning sign for when your battery is starting to wobble though, as Apple have outlined seven key things to look out for that signal a downturn in battery health when Performance Management is enabled:
- Apps taking longer to launch
- Frame rate decreases when scrolling on apps
- Backlight/brightness dimming
- Speaker volume decreasing
- Gradual frame rate reductions in certain apps
- Inability to enable flash in the camera app
- Background apps need to be refreshed when reloaded
Spotting any of these warning signs might signal that it's time to head to your nearest Apple store and switch out the battery, as you'd be surprised by how much of a difference it can make.

As exciting of a prospect that a new iPhone can be - especially with rumors of a folding variant on the horizon - you won't feel the need to upgrade any time soon if you opt for a battery replacement on your existing iPhone, and staying alert for the aforementioned warnings will let you know when it's time.
Additionally, you can also look at the battery health rating in your phone's settings, which shows you how your battery is faring, it's maximum capacity, and the number of times that you'd used the full capacity of the phone.
Experts recommend that you should probably start to think about a new battery at around the 500 cycle mark, although this can change depending on how you've used your phone and if you've utilized the Performance Management setting.
