Notice that your iPhone isn’t charging as quickly as it should? Review the following tips and make sure you have what you need to get adequate fast charging.

Use a power adapter of at least 20W to get fast charging on your iPhone

Regarding the iPhone 16 Pro battery issues, it’s good time to discuss an important topic regarding iPhone charging. Have you checked how long it takes to charge up to 100%? In this article we will review some tips to improve the charging time of your iPhonetaking into account power adapters, cables, and what you should avoid when charging your device.

What is the acceptable time to charge an iPhone?

According to Apple Support, It is possible to fast charge an iPhone 8 and later models up to 50% in 30 minutes. Loading speed It decreases until it reaches 80%especially if you have enabled Optimized Charging, which shuts it down completely based on your activity habits and then allows up to 100% charging. Above 80%, charging slows down and therefore takes around 2 hours to recharge an iPhone..

In compatible models it is possible to charge it wirelessly but it is necessary to have a MagSafe charger and a USB-C power adapter of 30 W or more to obtain 50% charge in 30 minutes. Otherwise, wireless charging is slower and therefore it is better to charge the iPhone using the charging cable.

If your iPhone’s charge time is more than two hours without optimized charging, on average you need to look into what’s happening and why it’s happening.

Use Apple’s 20W charger or a certified third-party charger

Those in Cupertino recommend charging the iPhone with the 20W power adapter for fast charging. Remember that since the iPhone 12, the power adapter is no longer delivered in the device box. It is necessary to purchase an official one from the Apple Store, authorized distributors or choose a certified third-party alternative compatible with Power Delivery. If you already have an adapter but are not sure if it is 20W, you should check the printed specifications as shown in the image.

If you own an iPhone 15 or 16 Pro Max, some third-party testing indicates you can get higher charging using 30 or 35W adapters.. If you have an iPhone 15 Pro or earlier, the 20W adapter is the best you can get. On the other hand, if you have a MacBook, you can use its adapter to charge your iPhone without any problem.

The charging cable must be correct

To use the correct cable for fast charging, You need to make sure it’s a USB-C cable on both ends in the case of iPhone 15 or 16 or a USB-C to Lightning cable for iPhone 14 and earlier..

You can always find a compatible cable in the iPhone box, so that’s the one you should use. Alternatively, you can also purchase an MFi certified charging cable. As for the cable, make sure that it does not show any damage or wear.. The ports should be with the pins aligned.

Coming back to wireless charging, the iPhone 16 is better

If you own an iPhone 16 and want to adopt wireless charging above the cable, you can buy the new MagSafe charger and a power adapter of at least 30W. You could have up to 25W of power until it eventually dwindles when the iPhone reaches 80% charge.

It’s worth mentioning that third-party alternatives don’t yet offer wireless charging of similar power.so if you use one of these you have to take into account that you will not achieve a speed higher than 7.5W.

Turn off optimized charging if you don’t want it to cap at 80%

Optimized Battery Charging learns a normal charging pattern when you are in a particular locationfor example from home. This means that when the iPhone reaches 80% charge, it will no longer charge to 100% after a few hours.

Avoid charging your iPhone on a Mac, PC, public places or other mobile

The charging ports on a Mac, PC, or any public place won’t give you a fast charge. These have a speed of 4-7.5W, so you won’t make significant progress. If you charge your iPhone with another iPhone, you will only achieve a speed of 5W, something similar to what the legendary power adapter offered that was no longer included until the iPhone 11 Pro.

Charge your iPhone in a cool place

Fast or wireless charging may heat up your iPhone during the charging process. If we add to the equation a hot, unventilated environment, temperature could double to the point that iOS limits charging of the iPhone at a slower speed.
