iPhone won’t turn on

So my problem today is, I have an x2 iPhone 7 Plus that won’t turn on and when I press and release the power button 1s, instead of the mA to read around 0.006mA and return to 0.000 as the power didn’t pressed long enough to read the phone, it will stuck within (0.005mA - 0.008mA) and if I test the PP_VDD_BATT, PP_VDD_MAIN and PP_VDD_BOOST they all read normal. Please help point me to the right direction to fix this problem, I even try removing the Charger IC and replacing it, yet still!
