Your phone's battery can have its life cut short thanks to wireless charging

For many consumers, the most important spec of a phone is its battery life. On some level, this makes plenty of sense. After all, it doesn't matter what the resolution is on your phone's display; without a charged up battery, that screen is not going to light up. Same with chipsets. It doesn't matter if your handset is powered by the Snapdragon 855 or the Snapdragon 439. A dead battery is the great equalizer.
Misaligned wireless charging will generate the most heat and shorten the life of a battery faster
The researchers compared charging a handset using the usual wired method to a wireless charging pad with coils that were aligned with the ones in the phone, and a wireless charging pad that was not aligned with the phone on purpose. Using the typical wired charging process, the temperature did not exceed 27 degrees Celsius/80.6 degrees Fahrenheit. Aligned wireless charging reached a peak temperature of 30.5 degrees Celsius/86.9 degrees Fahrenheit, but started dropping off during the second half of the charging session. Misaligned wireless charging resulted in a similar peak temperature, but it was hit sooner than aligned inductive charging and held that peak temperature for 70 minutes longer.
So here are some suggestions that you can follow to increase the longevity of your phone's battery while still using the wireless charging feature on your phone. Do not charge it in the heat. That makes sense, of course, and similarly, you should not charge it while running any complex tasks that will tax the processor inside the phone and generate heat. Remove your phone's case before you charge to make sure that the device can cool down, and if possible, make sure the coils on the pad are aligned with those in the phone.
The report doesn't mention the heat generated by one of the most popular new features on high-end premium smartphones today; reverse wireless charging. This debuted last year on the Huawei Mate 20 Pro and is available on the Samsung Galaxy S10 and Galaxy Note 10 lines. Reverse wireless charging in effect allows you to use the back of your handset as a wireless charging pad to share some of the battery life remaining on your phone. This battery life can be shared with compatible devices such as wireless ear buds and other phones. Apple is reportedly adding this feature to the upcoming 2019 iPhones to be unveiled next month.
