Does the iPhone 17 series have better battery life?
Yes. Apple is quoting its longest iPhone runtimes ever, with notable gains across the lineup:
| Model | Video playback | Video playback (streamed) |
|---|---|---|
| iPhone 17 | Up to 30 hrs | Up to 27 hrs |
| iPhone Air | Up to 27 hrs (40 hrs with MagSafe Battery) | Up to 22 hrs (35 hrs with MagSafe Battery) |
| iPhone 17 Pro | Up to 33 hrs | Up to 30 hrs |
| iPhone 17 Pro Max | Up to 39 hrs | Up to 35 hrs |
The iPhone 17 Pro Max sets a record with up to 39 hours of video playback. The slimmer iPhone Air, despite its smaller 3,149 mAh battery, is said to last a full day. Apple also designed a new low-profile MagSafe Battery Pack for the Air, extending playback to around 40 hours.All models now use stacked battery technology for higher energy density and longer lifespan. The Pro and Pro Max add a vapor chamber cooling system in their aluminum frames, helping sustain performance and improve efficiency under heavy load.On the software side, iOS 26 introduces Adaptive Power Mode, which learns from usage patterns and limits background activity only when necessary — a smarter, less intrusive upgrade over the old Low Power Mode.
How much battery do the iPhone 17 models have?
Apple doesn’t list battery capacities on its website, but the approximate specs are as follows:
| Model | Expected Battery Capacity |
|---|---|
| iPhone 17 | ~3,692 mAh |
| iPhone 17 Air | ~3,149 mAh |
| iPhone 17 Pro | ~3,988 mAh |
| iPhone 17 Pro Max | ~4,832 mAh |
How fast will the iPhone 17 series charge?
Apple did not spend too much time talking about charging upgrades, but there seem to be some improvements on this front too.
- iPhone 17 & Pro: 50% in ~20 minutes with a 40W adapter
- iPhone 17 Air: 50% in ~30 minutes with a 20W adapter, or faster with a 30W adapter
- iPhone 17 Pro Max: 50% in ~20 minutes with a 40W adapter
Does the iPhone 17 series have wireless charging?
Yes, all iPhone 17 models, including the new iPhone Air, have wireless charging.
- iPhone 17, 17 Pro, 17 Pro Max: up to 25W
- iPhone Air: up to 20W
Qi2 support means you now get full speeds with compatible third-party chargers, not just Apple’s MagSafe pucks.
Does the iPhone 17 series have reverse wireless charging?
No. While all 2025 iPhone models support reverse wired charging, Apple has not officially confirmed reverse wireless charging.
What charger does the iPhone 17 series use?
For best results, Apple is offering a new 40W Dynamic Power Adapter with 60W Max, priced at $39 in the U.S. (and also sold in Canada, China, Japan, Mexico, Taiwan, and the Philippines). When paired with this charger, the iPhone 17 Pro and Pro Max can hit 50% in just 20 minutes.
Apple is also selling a new Qi2-certified MagSafe Charger with up to 25W output, available in 1-meter ($39) and 2-meter ($49) lengths. These chargers unlock the full wireless charging speeds of the 2025 iPhones.
As expected, no charger is included in any of the boxes — only a USB-C cable. If you don’t buy Apple’s new adapter, a high-quality 30W–45W PD charger will still deliver close to peak speeds.
