When Apple rolled out iOS 18 earlier this fall, your current iPhone gained many great features and more. Customizable home screen and control centera redesigned, new Flashlight application iMessaging features, Wi-Fi sharing capabilities and the ability to hide and lock apps.

(And that’s not even touching on Apple Intelligence features that Finally launched on newer iPhones this week.)

Additionally, iOS 18 added a lesser-known feature – called “Charge Limit” – that gives you better control over how much your iPhone charges when it’s connected to power. This is intended to prevent your iPhone from fully charging and, thus, extend its lifespan in the long run.

The trap? The new feature only works on iPhone 15 and iPhone 16 models.

Protect the health of your iPhone battery

You probably know that your iPhone’s lithium-ion battery degrades over time. This is why it doesn’t last as long as when it was new. But you probably didn’t know that it’s also not good for the battery to be constantly charged to 100%. This causes its battery to degrade more quickly.

In an ideal world, according to Isidor Buchmann, CEO and Founder of Cadex ElectronicsIt’s best to keep your iPhone always above 20 percent or above 80 percent. And these new battery controls offered by iOS 18 aim to help with that.
