An easy way to discharge the battery yourself is to connect a small electric bead as a load, but you must use an electric meter to monitor the voltage change to prevent over-discharge.
Whether to choose a fast charger or a slow constant current charger, it mainly depends on the focus of your use. For example, friends who often go out to use digital cameras and other equipment should choose fast chargers. Do not place the mobile phone charger in humid or high temperature conditions, so as to reduce the service life of the mobile phone charger.
In the process of the charger, there will be a certain amount of heat. At normal room temperature, as long as it does not exceed 60 degrees Celsius, it is normal and will not damage the battery. Since the style of the mobile phone and the charging time are inconsistent, this has nothing to do with the charging performance of the charger of the mobile phone.
