  • Why can't charge charge to 99%: If it is a new battery, the battery is discharged for the first time (that is, the mobile phone is charged) and the inside of the battery is turned off, and then the battery can be charged up to 100% after recharging. If it is an old battery, it is discharged and recharged once. If it is still not, it is caused by a large internal resistance of the battery and an inconsistent capacity.
  • Why did you just install the battery and the percentage was not displayed, and obviously only 50% of the batteries were loaded to show 80%: The first time the battery is discharged, the battery is discharged (ie, the phone is charged). The inside of the battery is turned off, and then the battery is recharged and the balance is displayed. All digital power supplies are like this.
