Who looks at the 27W of maximum power supported by the iPhone 15 Pro Max during recharging you may think that a more powerful power adapter, such as a 30Wyou will be able to take the device from 0% battery and take it to 100% faster than a 20W — perhaps the most popular model today among Apple device owners —, right? Well, according to a loading test conducted by YouTuber Brandon Butchchoosing the fastest model may not be that advantageous.
More specifically, Butch had these two chargers do battle alongside the 5W e 12Win order to analyze which of them can recharge the flagship of the Apple faster and how much temperature they generate. The iPhones used in the test, it is worth noting, had their batteries completely drained before the “race” began in earnest.
First, the YouTuber compared 20W and 30W chargers. Right away, both started delivering their maximum power, but, to their surprise, it was the less powerful model that ended up making the iPhone turn on first. The dispute from then on, however, was quite fierce.
After 20 minutes, the iPhone with the 20W charger had 28% battery, while the 30W charger was already at 32%. However, both reached 80% battery practically together, following regarding an hour on the socket. It was there, in fact, that the iPhone considerably reduced the charging speed, going to something close to 2W(!) at times — even with all the charging optimization features turned off.
According to Butch, the 30W charger actually produced more heat than the 20W one, but by a very small margin — insufficient, according to him, to cause any damage to the devices’ batteries. In the end, the iPhone with the 20W adapter was fully recharged following exactly 2 hours and 21 minuteswhile the one with 30W reached 100% following 2 hours and 11 minutes — a difference of a measly 10 minutes.
With these results in hand, it was possible to conclude that, if you are looking for a charger for your iPhone 15 Pro Max, the 20W model may be the most sensible choice, given its lower value and the slight difference in charging speed. . Using a charger with a power greater than 30W will also have no effect, since the iPhone limits charging to 27W.
With the 5W and 12W chargers, things went much slower, obviously. The 5W model — which for years was the model provided by Apple in the box of its devices — was only able to fully charge the iPhone following long periods of time. 5 hours and 44 minuteswhile the 12W one did the job in 4 hours and 4 minutes.
The 30W charger managed to deliver a maximum power of 24,8W during testing; the 20W, 18,5W; the 12W, 6,8W and the 5W, 4,6W. Surprisingly, it was the 5W adapter that heated up the most during the tests, reaching 71°C. The 30W model, for comparison purposes, reached 35.5°C.
