    It is not the charging amp hours it is the discharging amp hours is what you need to know and if it is a BMS protection board issue then this is going to be hard to deal with depending on how and what type of protection board it is and how it communicate with the charging board on the phone

    One note if you were to do what I suggested earlier about getting good quality battery you could very easily hook up a multi meter and check just how much current your phone is using and you might get to the bottom of what going on with your phone

    Can you please tell what type of battery tester that you used

    Can you go into some details about the issue with these batteries that you have bought for this phone

    Also what options do you have active on your phone in the background like WiFi,Bluetooth and so on
    How can it be 5 differents faulty BMS board???
    I check the mAh charged with a tool and also using an external charger (renekton 250W) and the capacity where about 80%.
    The issue is the endunance. less than the 2 years old original battery (86% from accubattery). so Everything's consistent

      One note do not trust the battery application for phones I have not found one that is very accurate for letting you know battery life

      I have found that if you get something like a usb / phone tester they tend to be more accurate than the phone application for current going into your phone

      Are you open to having a battery pack on the outside of the phone
