Apple has released a new MagSafe charger firmware 255 also known as 10M1821, to replace the previous 247 (10M229) version. Most likely, this rollout fine tunes wireless charging for the new iPhone 14 models and the recently released AirPods Pro 2.
MagSafe Charger Firmware 255
Unfortunately, Apple doesn’t provide any release notes. It’s unclear yet what’s new, but we’re most likely dealing with bug fixes and performance improvements.
Fact: A series of iPhone 14 users have complained that their new devices are overheating faster than previous models during MagSafe charging and that the charing process is often paused to allow the phone to cool down!
More: We’ve also received reports of AirPods Pro 2 charging very slow wirelessly over MagSafe, prior to this update!

How To Update MagSafe Firmware 255
MagSafe chargers update automatically, over-the-air, when the optimal conditions are met.
To force the update place your MagSafe compatible device (iPhone 12 or later) on the charger and keep it connected to the Internet while charging.
MagSafe Firmware Not Updating?
If your wireless Apple charger hasn’t upgraded yet, you might try to remove the case from your iPhone while charging.
According to Victor, this is the trick that unlocked the firmware 255 update.
How To Check MagSafe Charger Firmware
To see if your charger has updated to the most recent 255.0.0.0 firmware, proceed as follows:
- 1. Connect iPhone to MagSafe charger.
- 2. Open Settings and browse for General -> Apple MagSafe Charger.
- 3. Check the Firmware Version.
Fact: If it shows 255.0.0.0 it has already updated. If you see 247.0.0.0, 188.8.131.52 or 184.108.40.206 it means that your MagSafe charger is running an older firmware version.
