Estimating iPhone Charging Time in iOS 17

iPhone Charging times Now Visible in iOS 26 Beta – HereS How to Check

CUPERTINO, CA – August 25, 2024 – Apple has quietly rolled out a highly requested feature in the latest iOS 26 beta: the ability to see an estimated charging time directly within the iPhone’s settings. This update provides users with a clearer understanding of how long their device will take to reach a full charge, a feature previously unavailable natively.For iPhone users constantly wondering about remaining charge time, this is a notable improvement. The new functionality displays the estimated time to reach both 80% and 100% battery capacity when the device is plugged in. Users have noted a potential difference in these estimates, wich Apple explains is due to the deliberate slowing of charging speed past 80% – a feature designed to prolong overall battery health.

Here’s how to check the charging time estimate on your iPhone running iOS 26 beta:

1. open Settings: Tap the Settings app icon on your iPhone’s home screen.
2. Navigate to Battery: Scroll down and tap on “Battery” within the Settings menu.
3. View Estimate: While charging, a charge time estimate will appear beneath the charging indicator. This will show the time remaining to reach 80% and 100%.

Why This Matters: Beyond the Immediate Update

This addition isn’t just about convenience; it reflects a growing awareness of battery health and user anxiety surrounding charging. Modern lithium-ion batteries degrade over time with each charge cycle. Apple’s optimized charging feature, and now this time estimate, are steps towards empowering users to make informed decisions about their charging habits.

Understanding Optimized charging & Battery Health

Apple’s iOS already includes “Optimized Battery Charging,” a feature that learns your daily charging routine and delays fully charging past 80% until just before you need to use your device. This reduces the time your battery spends at 100%, minimizing degradation.

Knowing the estimated charge time allows users to better understand how optimized charging is working and adjust their routines if needed. For example, if you know you have a long day ahead, you might choose to override optimized charging and allow a full charge, even if it means a slightly faster degradation over the long term.

Lock Screen Glance

For a quick check, the iPhone’s lock screen will also briefly display the estimated time to reach 80% when the device is first connected to power, providing immediate feedback without needing to unlock and navigate to the Settings app.

The iOS 26 beta is currently available to registered developers and public beta testers. The feature is expected to be included in the final public release of iOS 26, anticipated later this fall.

What is USB power Delivery (USB-PD) and how does it effect iPhone charging time?

Understanding iPhone Charging Architecture in iOS 17

iOS 17 introduces optimized charging features, but accurately predicting how long your iPhone will take to charge still depends on several factors.Apple’s charging system prioritizes battery health, meaning charging speed isn’t always constant. This article breaks down the variables and provides realistic estimates for iPhone charging time across different models and scenarios. We’ll cover everything from fast charging capabilities to the impact of battery health on iPhone power delivery.

Factors Influencing iPhone Charging Speed

Several key elements determine how quickly your iPhone charges. Understanding these will help you manage expectations and optimize your charging routine.

Adapter Wattage: This is arguably the most notable factor. iPhones support USB Power Delivery (USB-PD) for fast charging.

5W Adapter (typically included with older iPhones): Very slow charging.

20W Adapter (recommended): Provides significantly faster charging speeds.

30W or higher Adapter (USB-PD compatible): Can further reduce charging time, especially for iPhone 14 Pro/Pro Max, iPhone 15 Pro/Pro Max and later.

Cable Quality: Use a USB-C to Lightning (or USB-C to USB-C for iPhone 15 models) cable certified for USB-PD. Cheap or damaged cables can limit charging speed.

iPhone Model: Newer iPhone models generally support higher wattage charging and charge faster.

Battery Health: As your iPhone’s battery ages, its capacity decreases, and charging speed may slow down. Battery health impacts the overall charging efficiency.

Background Activity: Apps running in the background consume power,slowing down the charging process.

Temperature: Extreme temperatures (too hot or too cold) can negatively affect charging speed and battery health.

iOS 17 Optimized Charging: iOS 17 learns your charging habits and delays completing the charge to 80% until just before you typically unplug, reducing battery aging.

Estimated Charging Times for Different iPhone Models (iOS 17)

These estimates are based on using a 20W or higher USB-PD adapter and a compatible cable.Times will vary based on the factors listed above.

iPhone 15 Pro/Pro max:

0-50%: ~20-25 minutes

0-80%: ~30-35 minutes

0-100%: ~45-60 minutes

iPhone 15/15 Plus:

0-50%: ~25-30 minutes

0-80%: ~35-45 minutes

0-100%: ~50-65 minutes

iPhone 14 Pro/Pro Max:

0-50%: ~25-30 minutes

0-80%: ~40-45 minutes

0-100%: ~60-75 minutes

iPhone 14/14 Plus:

0-50%: ~30-35 minutes

0-80%: ~45-55 minutes

0-100%: ~65-80 minutes

iPhone 13 Pro/Pro Max:

0-50%: ~30-35 minutes

0-80%: ~50-60 minutes

0-100%: ~70-85 minutes

iPhone 13/13 mini:

0-50%: ~35-40 minutes

0-80%: ~60-70 minutes

0-100%: ~80-95 minutes

Older Models (iPhone 12 and earlier): Charging times will be significantly longer,especially with the 5W adapter. Expect several hours for a full charge.
