Since always, charging speed has been a topic of debate among Apple users. Now, with the arrival of the new iPhone 15 and its massive batteries, the question of which is the best charger has once again become a topic of conversation. Is the 5W, 12W, 20W, or 30W charger offered by the company better? While intuitively we might think that higher power means shorter charging time, this is not the only factor to consider. A recent comparison video sheds light on this mystery, and the result is both unexpected and interesting.
And the award for the most balanced charger for our iPhones goes to…
The video, just below these lines, ventures to answer the question of which is the best charger. In a truly meticulous test, the iPhone 15 Pro Max was charged with different adapters. The results are clear; the time saved using the 30W charger compared to the 20W one was only 10 minutes: 2 hours 11 minutes versus 2 hours 21 minutes, respectively. At no point during the test was there a difference of more than 4% between the battery levels while charging.
This leads us to reflect on the convenience of each adapter. If we only looked at the charging speed, it’s easy to lean towards the 30W adapter. However, when considering other factors, the situation changes, and the 20W option emerges as the most balanced choice. On one hand, we can talk about the size of the charger itself, something to take into account, but above all, we must address the issue of overheating. With the 30W charger, the phone reaches 45.5ºC, whereas with the 20W one, it reaches 41.6ºC, something to consider seriously.
While with the 12W charger, the temperature reaches 35.5ºC, and with the 5W one, it reaches 34.4ºC, we can’t dismiss these chargers. For times when we are not in a hurry and prefer slower charging overnight, these options can be more than sufficient and contribute to battery care.
And when we seek a balance between speed and generated heat, the 20W charger seems to be the most well-rounded option. Having said all that, and keeping in mind these 15 tips to extend battery life on iPhone 15, each of us will have our own personal preference. The best charger will be the one that meets our expectations and preferences. Nevertheless, with tests like these, we will have much more information to make the best decision.
