iOS 26 tells you how long it takes for your iPhone battery to complete charging
iPhone Battery Settings iOS 26 gets a great update including a new intelligent battery saver mode called Adaptive Power. The iPhone also now tracks additional battery statistics, including average power consumption throughout the day.
But perhaps the most notable enhancement is that it is able to accurately tell you how long it takes for your iPhone to charge its battery. At the top of the lock screen, you will see the estimated time that the phone will be charged until it reaches 80% when it is turned on.
So if your iPhone battery is below 80%, when you look at your iPhone, you’ll be charged to check the current time until the battery reaches 80%.
This feature is useful when using a variety of chargers. This is probably a combination of slow and fast chargers. Battery time estimates explain whatever your current charging speed is.
In the example above, the iPhone battery is currently 77%. The phone will be plugged into a slow charger, and the system predicts it will take another seven minutes to add a 3% battery.
Beyond the 80% mark, the battery charging time estimate is also available in the newly improved settings->Battery section. The top of this screen describes your current charging status, including the time to end charging. If the phone is removed, it reports the current battery percentage and the level that was charged when it last plugged in.

Another main section of the Battery Settings screen is a new chart that compares current consumption with daily and weekly averages. It also tries to tell you if your app uses more batteries than usual and why.
There are also new ones to make your iPhone even longer on a single charge Adaptability Switch on the Power Mode setting screen. This is alongside the low power mode as another way to adjust the trade-offs of longevity performance on mobile phones.
Here’s how Apple explains adaptive power modes:
“If your battery usage is higher than normal, your iPhone can adjust small performance to extend battery life, such as allowing you to slightly lower the display brightness or spend a little time. Low-power mode can be turned on at 20%.”
The explanation is a bit vague, but it sounds like the system is trying to check if battery usage is abnormal and conditionally compensates for device performance. This can mean that emails will be reduced regularly or that modes may take a little longer if the adaptive power is slotted into the device.
The adjustment sounds like it’s meant to be subtle (“slightly drop”, “a little longer”) so you shouldn’t actually notice that much of a difference. If you have enough battery and are not using it more than normal, the device’s performance will not change. This is why it is called adaptive function.
