We are receiving our new iPhone 16 Pro Max phones tomorrow and looking at new better wireless chargers (which have magsafe)

Our old Mophie wireless chargers are from 2020 and output at 7.5W

The new magsafe charger is 15W Qi2 and from Belkin

Question is, apart from seeing the phone will charge quicker, is there any benefit from the new one to ensure the battery health has better longevity? Or is there no other benefits?

Thanks
 
I suspected that my battery health (99% after one year) was so good because I charge my phone only with MagSafe charger. But in some other thread here someone said that it's definitely not related to that and also overall temperature and climate matters too.

So yeah no idea, but I still believe that slower charging might be better in general for the battery health.

From what I gather….faster charging is bad for the battery, and so is wireless charging, including MagSafe.

My opinion…don’t worry about it so much. I wireless charge my phone overnight all night every single night to 100% and never have an issue.
 
I don't use the fast MagSafe charging - gets too hot.

I will use my old 10W Qi charge pad when I put it down to sleep.
 
MagSafe only to charge my 15 Pro for the last year and I'm still at 100% battery health. On the charging stand most of the day and all night.
 
Ok thanks guys, will probably just keep our old 7.5W chargers then :)
I was on the same boat with you until I watched the iFixit video about wireless charging.

They are not fan and I don't care about that, but the point that they made about temperature was interesting.
If the wireless charger is not well aligned with the phone, more heat is produced.

Qi1 chargers (7.5W) don't have magnets.
So, there's a tradeoff between slow charging but generating more heat due a not-perfect alignment.
And you are generating more heat for longer time, since it's only 7.5W.

That made my mind to go to a Qi2 charger.

I used magsafe pretty much all the time, and my phone was at 93% after a year. So I don't know that this debate has a lot of evidence over which way is better
 
I got my iPhone 15 Pro Max late November last year. I’m at 97% after 213 cycles. ~90% of time it’s on a MagSafe charger.

We have went for two of these, for our bedroom side drawers beside our bed

Qi2 Chargers.
