iOS 26 Finally Shows When Your iPhone Will Finish Charging

iOS 26 Finally Shows When Your iPhone Will Finish Charging

With iOS 26, Apple stops guessing games and tells you exactly how long your iPhone needs to finish charging. iPhone users can see a time-based charging estimate instead of relying on battery percentages alone. It is a small change that makes everyday charging far more predictable.

iOS 26
You plug in your iPhone at 41 percent and glance at the clock. 

Will it hit 80 percent before you leave? 

Is ten minutes enough, or do you need to change plans?

Until iOS 26, iPhone charging was mostly guesswork. 

Battery percentages told you how full your phone was, not how long it would take to finish charging. 

Here's a Cool Tip:  Use iOS 26 to Estimate Your Charging Time.

iOS 26 now adds a charging time estimate that reflects real-world conditions.

How to See iPhone Charging Time

Feature Explanation

iOS 26 introduces an iPhone Charging Estimate that shows approximately how long it will take for your battery to reach full charge while plugged in.

iOS 26 evaluates the current charge level, charger type, power delivery speed, device temperature, and charging behavior. 

Based on those inputs, it calculates a live estimate that updates as conditions change.

Time is more useful than percentages. iOS 26 turns charging into something you can plan around instead of something you hope works out.

What You’ll Gain
  • Clear visibility into how long charging will take in iOS 26
  • Better decisions when using slow versus fast chargers
  • Less battery anxiety during busy workdays
  • Smarter charging habits without manual setup

Step-by-Step Instructions

Here's how to do it.

iPhone
  1. Plug your iPhone into a charger.
  2. Unlock your iPhone and open Settings.
  3. Tap Battery.
  4. Look for the charging status message showing an estimated time remaining.
