iPhone 13 Pro Max Capable of Faster Charging at Up to 27W Speeds

Despite not being advertised by Apple, the iPhone 13 Pro Max is capable of faster charging at up to 27W speeds when connected to a 30W or higher USB-C power adapter, according to testing conducted by ChargerLAB. For comparison, the iPhone 12 Pro Max is capable of charging at up to around 21W to 22W speeds with an equivalent power adapter.

It's worth noting that the iPhone 13 Pro Max does not sustain peak 27W power for the entire charging cycle due to heat considerations, but the device should still charge slightly faster than the iPhone 12 Pro Max overall.


It's unclear if the smaller iPhone 13 Pro is also capable of charging at up to 27W speeds — we've asked ChargerLAB and we'll update this story if we hear back. The standard iPhone 13 and iPhone 13 mini are limited to roughly the same charging speeds as the equivalent iPhone 12 models, according to a user on Chinese social media platform Weibo.

Apple no longer includes a charger in the box with new iPhones, but it does sell a 30W USB-C power adapter for $49 for users who want to charge their iPhone 13 Pro Max as quickly as possible in light of this discovery.

Update: ChargerLAB has informed MacRumors that the smaller iPhone 13 Pro achieved max charging speeds of 23W in its testing.

I’m charging overnight with my 5 watt brick. Works fine and has lasted me
pretty much all day. No sense of creating extra heat by quick charging unless you really need a quick boost during the day.

I plug my iPhone into a 100W Anker multi-charger via USB-C. I wonder if the Anker will deliver the full 27W at any point or if it will fall back to 18-20W?

I do have an extra 30W charger I could use since that should definitely work.
Only 100W? I plug mine into a 3KW gas powered generator. It charges fast and the fumes help me sleep. I just need to remember to not set the timer too long.

When I was using my MBP brick to charge my iPhone 13 Pro Max during the set up it kept saying the restore process stopped due to device temperature so I had to rub an ice cube on the back of the phone so it would continue restoring my iCloud backup.

Surprised people care about battery health. I don’t care I rather have my phone charge faster.
One part is environmental, another part is "score keeping". Some people would rather tout 98% battery life after 1 whole year doing trickle charging versus 89% and constantly wired. It doesn't particularly save anything though, if it means updating the phone every 1 to 2 years. (here comes the downvotes!)

I'm not sure why anyone would downvote you for this sensible, quality post but I did because I know how rewarding it can be to predict something and then have your prediction come true

Words of advice:
If the iPhone gets HOT (not just warm) when using one of these chargers on a warm day — “you’re charging it wrong”
