Remove Protective Case
Phone manufacturers typically have a list of protective cases that they have certified for use with particular devices. This is because they are aware that these devices are capable of securing the phone without causing overheating problems if the phone is in a long charging session. If the phone overheats because it is in a case not conducive to battery temperatures at charge time, it further damages your phone.
There are other reasons, some very specific to particular devices and to particular cases. Because there are so many cases on the market to choose from, they may all have their own pros and cons. With so many variants, phone manufacturers can’t account for all of them.
Let Your Battery Drain (Occasionally)
To get rid of the full charge/discharge effect, most phone manufacturers recommend that once about every three months, you allow the phone to drain to 0%, and then immediately plug it in to charge, letting it get up to 100%.
