Enhancing charging efficiency and shortening waiting time are now more pressing needs for iPhone users. Based on these expectations, we have summarized a string of useful tips about charging, which can help everybody maximize the charging speed of their iPhones effectively and prolong the service life of their batteries. For efficient charging of the iPhone, use high-power USB-C PD chargers and original or certified data cables; Airplane Mode or Low Power Mode should be turned on to reduce power consumption. Avoid using the phone while it is being charged so all the resources of the battery will be oriented to take in power from the charger. Take the phone case off while being charged, for it to ensure better heat dissipation and maintain the right ambient temperature. These measures can increase the charging speed by a huge margin, therefore also prolonging the life of a battery.

1.Use a high-power charger and data cable
- Use High-Power Chargers: Apple has supported fast charging since iPhone 8, and ever since then, it has been increasing support for charging at increasingly higher powers. For the iPhone 12 series and later models, use a USB-C PD fast-charge charger of at least 20W; these chargers have a USB-C interface and support the PD protocol for efficient charging communication with iPhones to realize faster charging speeds.
- Using Original or Certified Cables: When purchasing your charging cables, try to use Apple’s original or MFi certified cables. These undergo rigorous testing and are compatible with iPhones, ensuring stable current and voltage output, which hence guarantees efficient charging and no perils associated with usage. The result of having a non-certified cable could be a slow charge, unstable data transfer, or even damage to the device.
2.Enable Airplane Mode or Low Power Mode
- Airplane Mode: Turning on Airplane Mode is another easy and quick technique that charges your iPhone even faster. Airplane Mode will simply turn off all of the wireless connectivity features of your mobile phone, including cellular networks, Wi-Fi, Bluetooth, and GPS. This means that during charging, the phone won’t try to connect to any network or device, and hence it will significantly reduce power consumption from background activities.
- Low Power Mode: Even though this Low Power Mode is normally designed to extend the device’s battery life in times when it’s at a low percentage, it will also have a role during charging. If Low Power Mode is turned on, your iPhone will adjust performance to lessen power consumption by, among other things, dimming the screen, limiting activities in the background, and pausing some system animations. These measures are equally efficient while in charge, because the more the phone reduces its power consumption, the more it’s able to push towards actually charging the battery.
3.Avoid using your phone while it’s charging
For instance, making use of your charged phone dramatically reduces charging effectiveness and extends the charging time. This is logical because surfing the net, playing games, watching a video, and making calls involve high power usage to perform numerous tasks.
In the event that the phone is under charge while being used, then the process will require the required amount of power to meet the charging needs, while the battery will also supply power to the present use. It is generally regarded as better to avoid using the phone during the charging process and thereby allowing the battery to focus on absorbing the power input from the charger, which results in a quick and secure process of charging.
4.Remove the phone case to optimize charging
This, therefore, calls for the main need for occasionally removing the phone case during charging to boost charging efficiency and further reduce the reduction of charging speed due to overheating. This will be the direct access of the phone to the air and hasten the rate of dissipation of heat while keeping the phone within a substantial working temperature range.
Especially when charging with a high-power charger, the phone case should be removed, because during fast charging, the temperature is relatively high and it has a greater requirement for a good heat dissipation environment to ensure that the charging is efficient and the battery is safe. Regularly cleaning dust and dirt off the back of your phone will help in better dissipating heat and speed up the charging further.
5.Optimize Charging Environment
Apple advises that an ambient temperature of 0°C – 35°C be maintained while charging, as it is at this temperature range that the battery has its optimal chemical activity; therefore, maximum charging efficiency and maximum life. When the temperature is too high, the chemical reaction speed inside the battery is increased, producing more heat. This will increase stress on the battery, slow down charging, and even cause permanent damage to the battery. On the other hand, this low-temperature environment is going to slow down all the chemical reactions inside the battery, making the charging speed become slower and affecting the endurance capacity.
