If you have bought a new phone in the last 2 years, the device is likely to charge fast . However, if you’ve bought an iPhone , bad news, it won’t charge as fast as its counterparts in the Android ecosystem. Because of this, you may well be wondering, is it safe to use a more powerful charger with Apple phone?
Let’s dive right into the security issue. Manufacturers of fast chargers want to sleep easy and that is why they have put a special emphasis on making their products safe to use. This is why charging a device depends on what the phone itself supports, and not what the charger is capable of delivering. Otherwise, we’d all be using 120W chargers to top up our phone’s battery in mere minutes.
But no, it doesn’t work like that. Basically, we can say that what happens when you connect the iPhone to the charger of, for example, the Xiaomi 12 with a 67W charge is nothing. Neither for better nor for worse, both ends of the current will agree and decide to limit the power.
Fast chargers on iPhone
The fastest you’re going to be able to take the iPhone battery from 0 to 100% is at a speed of 27W . This is not something that the company declares in the specifications of the phone, since it only announces that you can recharge up to 50% of your phone’s cell in about 30 minutes, as long as you have an iPhone 8 or higher.
To meet these numbers, you need to use an Apple USB-C to Lightning cable and one of the manufacturer’s USB-C power adapters. These can be 18, 20, 30, 61, 87 or 96 W. What happens is that all those that offer a power above 30W will have the same effect on the charging speed, as this graph shows.
It doesn’t matter if you have a charger of 87, 61, 35, or 96 W… none of them will be able to charge the iPhone faster and all of them will be below 27W of power. This is because the iPhone does not support top-up charging and therefore the current is limited.
In short, using a fast charger on the iPhone is not going to compromise the integrity of the phone, but it is also not going to replenish the cell’s energy faster. Therefore, if you are thinking of buying one, you do not need to look at the most expensive and fastest, only that it has the necessary security systems and that it is compatible with the limited charge of your smartphone.
How to fast charge iPhone
If you want to save time when recharging your device , there are other better things you can do instead of looking for faster power adapters that, as you just saw, do not help much.
- Turn off the phone while it charges : By letting the processing power sleep and making the screen turn off, you will gain a few minutes while charging the phone, although it is not a big deal.
- Lock the screen: Along with the processor, the screen is the biggest ‘battery killer’ of your phone’s battery. If you can’t live with a phone off, let your screen lock to charge faster
- Turn on Low Power Mode : When you reach a certain battery level, this setting changes screen resolution, animations, background app refresh, and other battery-draining features. By activating it, you will charge the mobile faster.
