As we all know, the batteries of both tablet computers and mobile phones are lithium batteries now, because lithium batteries can store more electricity and are more convenient to carry. However, due to the principle of charge and discharge, this may lead to the loss of ions during charge and discharge. This will reduce the storage capacity of our mobile phone battery to below 80. Of course, playing with the mobile phone properly and storing electricity can save its service life. For example, we can control the power of the mobile phone between 60 and 80, and the service life of the battery is the longest between this point. At the same time, don't use less than 20% of the battery power, and don't charge more than 80 when charging. The above is the content of this issue, I hope it will help you.
