Should you or shouldn’t you? That seems to be the age-old question when it comes to whether or not you should charge your phone to 100 percent in the hopes that this will lessen the number of times you have to seek out a charger.
But other concerns have arisen in this full-charge debate. Some tech experts say charging your phone to its full capacity is actually worse for your battery and that there is a sweet spot when it comes to a charged phone: it should be kept between 30 and 80 percent charged.
What does Apple Explained have to say about the matter?
Let’s find out once and for all: should you charge your iPhone to 100 percent?
You Should NOT Charge To 100 Percent
Let’s get right to the point: tech experts do not approve of charging your device way up to 100 percent on a regular basis. The type of battery used by your phone is lithium-ion and it is only useful for so long before it begins to degrade. (You can check your battery health in settings to see where you stand).
Charging to 100 percent and then allowing your battery level to dip all the way down is considered a “Deep Discharge” that “exhausts the lithium battery cells faster than charging to 80 or ninety percent.”
Finding a charger only when your battery dips down to 30 to 40 percent can ensure your phone is constantly charged when you need it, but can also prevent performance issues.
For what it’s worth, Apple is trying to alleviate these battery issues by offering settings such as Optimized Battery Charging, which learns your daily charging routine so that it can wait to finish charging past 80 percent until you need to use it. If Apple senses you aren’t charging your device properly, it will send you an alert that your phone should be removed from its power source and discharged to improve battery health.
You can also take advantage of Low Power Mode, a setting that decreases the number of functions your phone can perform but, in its place, stalls battery decline so that your charge lasts longer.
