iPhone 16 Pro Max Has anyone seen 45W charging on iPhone 16 yet?

Picked up my 16 Pro Max today. I let the battery get down to 1% to test the 45W charging, but so far 32W is the highest sustained power I’ve seen and it’s already up to 60%.

At 20% I unplugged it to let it cool down, and I added a strong fan to keep it cool for the rest of the test. I unplugged it again at 40% to cool. Used a 96W Apple USB-C adapter and the original usb-c cable, also tried a few other cables. I’m pretty sure my meter is accurate because it shows a steady 28W when I charge my 15 Pro Max.

Curious if anyone’s seen 45W yet, or has an idea about why there’s a discrepancy? I’m relatively confident my testing setup isn’t to blame, but I guess anything’s possible. My only other guess would be that Apple is limiting it until the battery has a gone through a few cycles, assuming that would help with degradation.

One theory I read is that the phone can't "charge" at 45W, but if can draw 45W if it's charging and you're doing something energy intensive like playing a game with complex graphics, etc.

To talk charging, you’ve got to give us information.

What charger are you using? What are the specs of the charger (as written on the charger itself, e.g. 2a x 5v)? Is it a USB-C PD PPS charger? What cable are you using?

Those are all important variables.

Tom's Guide review of the 16 Pro Max says that reports of 45w charging are not accurate and were just rumors.

"Unfortunately, the iPhone 16 Pro and Pro Max still offer the same lame charging speeds. You get just over 30% capacity in 30 minutes from a 30W charger. And do not believe the reports that the new iPhones support 45W charging. We tried it, and it made no difference."

That was honestly the biggest thing I wanted in the new phone and didn't even now about it till after I ordered it...

phone is charging off my 15PM while doing data transfer. I have some accurate equipment and will test myself and cross all my fingers and toes.

tested with a USB V meter and it never goes above 30W, whether it’s an Apple charger or a PD 3.1 PPS charger.
I’m also running 18.1 beta

I tested with my usb charger monitor and it did spike a few times into the 31-33W range but it deff wasn’t sustained

It’s not 45w charging it’s same as before

I’ve seen my 16 Pro Max peak at 41W, but it usually bounces between 32W and 38W. This is on a relatively cheap BOERX 240W charger that supports up to 100W on USB-C (verified on a USB-C power meter). edited to add: using an off-brand ThunderBolt 4 cable rated for 100W.
