Not every phone battery can be “shaken”. Lithium-ion batteries lend themselves best to this procedure. They will be discussed in the future. There are, of course, completely hopeless cases when the battery completely loses its capacity and cannot be revived by any means, but for the most part, lithium-ion batteries are amenable to "swinging".
Necessary
Battery, phone, phone charger
Instructions
Step 1
First, discharge the battery to a state until your phone turns on at all. To do this, the battery must be in the phone. Better to completely discharge the battery, load the phone with power-intensive applications. Listen to music, play games, or simply press buttons. In the absence of energy-intensive applications on the phone, it also absorbs energy very well to turn the phone on and off for full discharge. The fact is that when searching for networks, the phone spends a lot of energy.
Step 2
When the battery is completely discharged, charge the phone. You need to charge until the battery is fully charged. After the first discharge-charge cycle, the battery will restore its capacity not to the maximum possible. For best results, repeat this cycle a couple more times. In the future, this procedure must be repeated after 50-100 phone charges.
