Temps de lecture 5 min
Apple’s iPhone 16 series has made some minor but noteworthy changes when it comes to charging. The iPhone 16 supports up to 45W wired charging via USB-C, and using a MagSafe charger increases the charging speed up to 25W with a 30W adapter or higher, a significant difference from the previous 15W. Let’s break down what this means for users, and how it compares to past models.

What’s New About iPhone 16 Charging?
The iPhone 16’s wired charging speed was reported to cap up at 45W, according to certification documents, which is a huge leap from the iPhone 15's 20W. The iPhone 16 line is expected to have 5-15 volts and 3 amps charging capabilities, 50% faster than the iPhone 15 series, which can only max up to 27-29W.
Very surprising news, iPhone 16 supports 15V3A and 45w charging power. It's exactly the same as the S25 Ultra leaked yesterday.（Is it limited to China version?） pic.twitter.com/0LSG3JrwaU

Meanwhile, the iPhone 16 has the following Qi and Qi2 wireless charging speeds:
Qi Wireless Charging: Up to 7.5W
Qi2 Wireless Charging: Up to 15W
The iPhone 16, however, slightly improves on MagSafe charging, now supporting up to 25W wirelessly—5W faster than the iPhone 15. Apple officially confirmed this and even made available the new 25W MagSafe Charger.
🔑 Key Takeaways:
The iPhone 16 can support up to 45W wired charging, 50% faster than iPhone 15 series.
Upgraded to 25W, MagSafe now offers faster wireless charging compared to previous iPhones.
Apple prioritizes moderate charging speeds to balance performance and long-term battery health, especially when compared to high-speed Android charging systems.
For optimal performance, use MagSafe-compatible cases, avoid overheating, and clean your MagSafe charger regularly.
Wired vs. MagSafe Charging
The wired and MagSafe charging key difference lies in convenience vs. speed. Wired charging is still faster when looking at the raw numbers (especially with chargers above 30W), but MagSafe’s wireless solution gives more flexibility for those who prefer a clutter-free charging setup. The 5W increase in wireless charging might not sound like a huge leap, but it can shave off some minutes over the long haul when compared to the previous 15W or 20W wireless charging speeds.
While many flagship Android devices have pushed for extremely high wattages like 60W or more wired charging, Apple’s focus has been more on balancing speed with battery health, ensuring longevity over time.
For everyday users, this means your iPhone won’t charge as quickly as some Android competitors, but it could help preserve battery life over the long term.
How Does It Affect Battery Life?
Charging speed and battery health often go hand in hand. Rapid charging at high wattages (up to 100W) can generate heat, which, over time, could degrade battery performance. Apple’s decision to stick with these relatively moderate charging speeds suggests an emphasis on battery longevity.
While the MagSafe 25W boost will cut down on wireless charging time, it’s still slower than wired charging, which remains the most efficient way to juice up your device.
Who Will Benefit from These Improvements?
Users who prefer wireless charging will enjoy the convenience of placing their iPhone 16 on a MagSafe pad and seeing slightly quicker charge times compared to the previous generation. Faster MagSafe charging on the iPhone 16 could benefit several groups, including:
- Heavy users
- Travelers
- Tech enthusiasts
- Productivity-focused users
However, those in a rush might still opt for a wired solution. In everyday life, the added 5W MagSafe speed isn’t a game-changer but does make wireless charging a more practical option for regular use.
Tips When MagSafe Charging
If you’re planning to take advantage of MagSafe charging with your iPhone 16, here are a few tips to ensure you get the best experience:
1. Use a MagSafe-Compatible Case.
If you like using iPhone 16 series cases, make sure it’s MagSafe-compatible. Thinborne cases have built-in magnets that align perfectly with the MagSafe charger while adding protection without the bulk. A regular case without MagSafe support may interfere with the magnetic connection, resulting in slower or inconsistent charging.
Thinborne's case is made of:
- Premium 600D Aramid Fiber
- Super Slim 0.04 Inch & Lightweight
- Perfect Fitment with Precision
- MagSafe Compatibility
- Gorgeous Carbon Fiber Textures for Grip
2. Position the Phone Correctly.
MagSafe is designed to automatically align with your phone’s charging coil, but occasionally, misalignment can still occur. Ensure the phone snaps perfectly into place with the magnets to maximize charging efficiency.
3. Monitor the Temperature.
Wireless charging generates more heat than wired charging, and excessive heat can affect your iPhone’s battery health over time. Charging your phone in a well-ventilated area can help manage this. If you notice your phone getting too warm, try removing any case, or avoid charging in hot environments.
4. Keep Your MagSafe Charger Clean.
Dust and debris can build up on the charging surface and affect how well your phone charges. Periodically wipe down the MagSafe charger with a dry cloth to ensure it maintains a strong magnetic connection and efficient charging.
5. Use an Apple or Certified Charger.
To get the full 25W charging speed, ensure that the MagSafe charger you’re using is either made by Apple or certified under Apple’s “Made for MagSafe” program. Cheaper, uncertified options may not support the full speed and could even cause overheating.
These tips can maximize your iPhone's and its battery's performance and longevity while using MagSafe.

Wrap Up
The iPhone 16’s charging capabilities represent an incremental but welcome upgrade, particularly in the MagSafe department. While it may not match the rapid speeds of some Android flagships, the balance Apple aims for between speed and battery health will likely appeal to users looking for long-term reliability.
Frequently Asked Questions
Can I charge my iPhone 16 with a non-MagSafe wireless charger?
Yes, the iPhone 16 supports standard Qi wireless chargers, but it will charge at a slower rate (up to 7.5W) compared to the 25W available through a MagSafe charger.
Is fast charging bad for my iPhone’s battery?
Apple’s charging systems are designed to balance speed and battery health. While faster charging does generate more heat, Apple manages this to minimize long-term damage to the battery.
Does the iPhone 16 come with a charger in the box?
No, similar to previous models, the iPhone 16 does not include a charger in the box. You’ll need to purchase a compatible 20W or higher power adapter separately.
