The Best New Battery Feature in IOS 18 Is Only Available for the IPhone 15
Now that the iOS 18 developer beta is out, we’ve learned about some new and exciting features that Apple didn’t mention in its major announcements at WWDC. One of them is advanced charge limit options, and while it may seem counterintuitive, they can actually help your iPhone in the long run.
New charging limits for iPhone 15 models
Apple is expanding charge limiting capabilities on all iPhone 15 models. Unfortunately, the new features are not available on older devices.
Users can now turn off their iPhone’s charging when it reaches 80%, 85%, 90%, or 95% charge. Previously, options were limited to 80% or “Optimized Battery Charging,” which charges based on your charging habits. Of course, you can also turn off charging limits.
If you’re wondering why you’d want to use this, it’s because limiting a device’s maximum charge is a common way to increase its battery life. Mac users have been doing this for years using third-party tools like Battery Toolkit . Limiting charging to 80% can actually help extend the life of your battery, but it also reduces the battery life at one time. Perhaps limiting charging to 90% provides a better balance.
According to a Reddit post , users who throttle charging will also be able to temporarily enable 100% charging, which will help when you’re traveling or when you have a full, busy day ahead of you.
According to MacRumors , Apple will also send notifications to users urging them to turn on the charge limiting feature, which should help with its adoption.
iPhone 15 users will find this feature in Settings > Battery > Charging .
Is your fast charger really fast?
The charging graph on the Battery page also becomes more useful. Apple will now recognize low charging as orange and normal/fast charging as green.
This feature could be a good way to find out if your Qi wireless charger is working well or if your old MagSafe charger is actually charging your iPhone at 15W as promised. Sometimes third-party adapters and wireless chargers aren’t all they’re cracked up to be.
