What is the best way to charge your iPhone?

We will not go through every single type of charge and method that has ever existed, but we will go over the ones the people ask the most questions about, plus the ones you should know about to keep the device’s battery in good health.

iPhone charging methods

Fast charging, fast charging, fast charging and turbocharging

Is there a difference between fast charging, fast charging, turbocharging and fast charging? For the most part, no. They generally refer to a method of charging at higher speeds than normal to achieve more charging in less time. Originally created by Qualcomm, Apple’s supplier of processing chips for many of its devices, the term “Quick Charge” is the basic term here and refers specifically to devices that include Qualcomm’s chipset and power management features.

Apple usually uses the term fast charging, although the chips are Qualcomm and technically Quick Charge 2.0 and 3.0 are equipped. Adaptive fast charging is also a term you want to hear, and the “adaptive” part of it simply refers to the device’s ability to reduce charging when it approaches 100 percent, or after the saturation point. Long story short, these terms are often used interchangeably.

The nice man here is fast charging. Fast charging is more of a brand or marketing term, and is not exclusive to devices that have Qualcomm chips, unlike Quick Charge 2.0 and 3.0. However, Quickcomm’s Quick Charge is upwards of 40 percent faster than fast charging.

The next top question is this: Does fast charging or fast charging damage my iPhone battery? This is a divisive issue, but the informed consensus is no, it does not. Yes, there is extra heat output from faster charging, but it is also with slow charging. The best way to take care of your iPhone battery is to perform regular maintenance and use optimization.

Which Apple devices support fast charging?

Fast charging or fast charging works on iPhones and iPads, and only with an Apple USB-C to Lightning cable. For iPhones, fast charging can charge your phone up to 50 percent within about 30 minutes. If you have any of the following devices, you will be able to charge quickly:

  • iPhone 8, 8 Plus and newer
  • iPad mini 5th generation
  • 3rd generation iPad Air
  • iPad Pro:
    • 12.9-inch, 1st generation and later
    • 11-inch, 1st generation and later
    • 10.5-inch

Adapters that can charge quickly:

  • Apple 18W, 29W, 30W, 61W, 87W and 96W USB-C (check the power on the bottom of the adapter if you are unsure)
  • Third-party USB-C adapters with comparable watts that support USB-PD, which stands for USB Power Delivery

What is Trickle Charge?

Without being overly technical about the electric charges and the ways they work, maintenance charging is basically a way that batteries try to maintain a 100 percent charge while they are already fully charged, but still connected to a charger, since some incremental loss of charge occurs natural. This is a process that is not healthy for the lithium-ion batteries in Apple products.

Keeping your phone plugged in when it’s already charged can wear a lithium-ion battery, according to Battery University, so it’s not a good idea to let your iPhone charge longer than you need. In Battery University’s words, “Li-ion does not need to be fully charged, nor is it desirable to do so. In fact, it is better not to fully charge, because a high voltage stresses the battery.”

Charge your iPhone by connecting to a computer

This is absolutely safe if you do it right. Use your regular iPhone USB charging cable, and keep your iPhone locked if you do not want to do anything computer-related other than charge it. As long as your computer is plugged in while you charge it to avoid draining some of the battery, Apple says you’ll be fine!

What you need to know about chargers and cables

Is wireless charging bad for iPhone?

No, it’s not insecure or bad for the iPhone, but it’s not as fast as wired charging, and certainly not as fast as fast charging. Apple recommends that you use only a Qi-certified charger, so make sure the charger you use is properly certified. If you have an iPhone 8, 8 Plus or later, you can charge it wirelessly. You can learn more about Qi charging here.

Is cable charging best?

In a word: yes. But only because it is faster and more reliable. I like The New York Times article on how to choose between wired and wireless charging; It is largely a choice of convenience, with few exceptions.

MFi-certified chargers and cables

This is an area where I never recommend skimping. It’s about a few dollars more for the certified USB cable against long-term and costly damage to the iPhone battery and potentially the phone itself. Cables that are not able to sniff may not have the necessary guarantees in place to control the power of the device’s battery, which can result in surprising amounts of damage to such a small accessory.

MFi stands for Made for iPhone / iPad / iPod. Fake charging cables and adapters will not carry the MFi mark. The certification mark should look like one of the marks you see below.

Made for iPhone certification means you should not see problems such as:

  • Damaged or broken cables after a short time with normal use
  • iOS device damage
  • Problems with synchronization and charging
  • Overheating
  • Poor space in the device or adapter

Other top questions about iPhone charging

Is it safe to use the iPhone while it is charging?

Yes, it is safe to use iPhone while charging. Just be aware of your choice of charger and cable, as the only times users tend to see problems with overheating are when using third-party or third-party accessories that do not comply with the safety pattern. Speaking of which:

Will using a non-Apple charger cable or adapter damage my battery?

Apple recently released a document describing which third-party chargers support fast charging, so it’s always good to know if you want faster charging without the hefty Apple price tag. Be warned though: the USB or lightning cord you use can mean the difference between charging your iPhone or ruining your $ 1000 investment. If you choose a cheap one that is not manufactured according to MFi standards (Made for iPhone / iPad / iPod), you can accidentally do some serious damage.

In fact, Apple spells this out quite clearly in its iPhone user guide:

You can also charge iPhone with “Made for iPhone” or other third-party cables and power adapters that comply with USB 2.0 or later and with applicable country and international and regional security standards, including the International Standard for Security Information Technology Equipment (IEC 60950-1). ) and the standard of security for audio / video, information and communication technology equipment (IEC 62368-1). Other adapters may not meet the applicable safety standards and charging with such adapters may present a risk of death or personal injury. ”

Should I take off my phone bag before charging it?

In some cases, yes. If your phone is already hot or hot due to environmental factors, it is often best to remove the case to prevent even more battery-generated heat from charging.

If you are concerned about wireless charging, it is a completely different thing. If your case is meant to support wireless charging, you do not need to take the case off. If you notice that the phone does not charge normally when the case is on, you can reduce the power of the charger to charge the iPhone battery. Some cases that are more robust tend to be thicker and harder for chargers to penetrate. Try to take the case off if you notice problems; it can help!

Do I have to charge the iPhone for several hours the first time I charge it?

No. This was an old requirement, and no longer really applies. Read the instructions in the box with the new iPhone to be safe, and learn more about optimal charging levels here.

Can I use the MacBook charger to charge my iPhone?

Yes, if it uses a 10W or 12W USB adapter. You can check the power on the bottom of the MacBook adapter if you are unsure.

Do “Instant Chargers” or “Miracle Chargers” Really Work? Are they safe?

It depends on how you define “work”. Can these chargers charge your battery in a minute? Maybe sometimes. Is it good for the battery? Absolutely not; This is one of the fastest ways to burn through a battery and potentially damage other device components.

Do I need to let the iPhone battery die completely before charging it?

Most of the time, no. Erasing or resetting “battery memory” refers to an old practice of letting phone batteries be completely discharged and then fully charging them at once to “reset” the battery. This is not required or actually recommended for lithium-ion batteries such as those used in Apple products. However, we have other recommendations for optimizing the health of your iPhone battery, including once you should fully discharge the iPhone battery.
