The new iPhone lineup is bringing significant charging improvements for users. The new iPhone 18 Pro models and iPhone Duo are gaining noticeable upgrades that will make it more convenient for users to charge up their devices.
While the iPhone 18 Pro Max focuses on faster wired charging and an all-day battery life, the iPhone Duo brings a new dual-battery system that is designed specifically for its foldable form factor.
Let’s take a look at the faster charging capabilities of the new iPhones.
iPhone 18 Pro: 50% Charge in around 15 minutes
The iPhone 18 Pro and iPhone 18 Pro Max both support faster wired charging, which will let users charge up to 50% in around 15 minutes. Of course, you will need to use higher-capacity USB-C chargers to achieve these speeds. This makes the Pro models significantly more easier when you need a quick boost before heading out.
Apple has also highlighted the charging performance of the iPhone 18 Pro Max for video playback. It says the device can deliver up to 7 hours of video playback with just 5 minutes of charging, which is impressive.
iPhone 18 Pro Max delivers up to 45 hours of video playback
The faster charging is accompanied by a large improvement in battery life. iPhone 18 Pro Max can deliver up to 45 hours of video playback. This is 6 hours more than the iPhone 17 Pro Max it is replacing.
Apple says the improvement comes from a combination of larger battery size and greater power efficiency. So how does it perform in mixed everyday use? Well, the company claims the iPhone 18 Pro Max provides up to 30 hours of use per charge with mixed activities such as streaming, gaming, and browsing throughout the day.
iPhone Duo gets 50% charge in around 20 minutes
iPhone Duo brings innovations to iPhone charging. Apple’s first foldable iPhone features its first dual-battery system, which takes advantage of internal space more efficiently. Apple has also made iPhone Duo eSIM-only worldwide to maximize the room available for battery capacity.
iPhone Duo is equipped with Apple’s C2 modem, which, according to the company, delivers improved efficiency. Despite its foldable design and large displays, Apple says iPhone Duo should be able to deliver a full day of scrolling, gaming, and other activities on a single charge.
Apple says the foldable can provide:
- Up to 31 hours of video playback when using the inner display
- Up to 44 hours of video playback when using the outer display
iPhone Duo is capable of achieving up to 50% charge in just 20 minutes of fast wired charging. It also supports MagSafe charging however, that would be limited to 25W.
To sum up, here’s the charging comparison between all of Apple’s newest iPhone models.
| Model | 50% Charge | Video Playback |
| iPhone 18 Pro | Around 15 minutes | Up to 36 hours |
| iPhone 18 Pro Max | Around 15 minutes | Up to 45 Hours |
| iPhone Duo | Around 20 minutes | Up to 31 hours inner/44 hours outer screen |
The iPhone 18 Pro models are the clear winners when it comes to charging speed, reaching 50% in around 15 minutes compared to around 20 minutes for the iPhone Duo.
However, the iPhone Duo’s charging performance is particularly notable considering its foldable design and dual-battery architecture.
