How to properly warp charge(5500 mA+) via OnePlus Nord Gray Onyx

    A lot of people complain about slow charging so i made this thread on how to get the advertised charging rate(5500mA).Some points you need tp read first.

    1. Optimised charging does not make a difference.
    2. Warp charging only guarantees 5500mA in Lab conditions as told by oneplus.
    3. Warp Charging only effectively works in 0-60% charge rate ,afterwards max current will be limited to ~4400mA.
    4. After 90% current severely drops to ~2200mA.
    5. Charging Speed/Current ONLY depends on the ambient temperature of your battery and has 3 phases( attached with screenshots below). The values presented are approx.

    Battery cool(<34°C)- 5500mA

    Battery warm(34°C-37°C)- 2800mA

    Battery hot(38°C+)-1800mA

    To conclude, In indian environment, most of the time you will not get the FULL warp charge(5500mA) unless it's Cold, or you have been sitting in an AC.

    I used the app "Ampere" for this data and have submitted a bug report as well to increase the temperature cutoffs but If anyone wishes to differ from this or disprove this, Please post screenshot clearly mentioning the following while charging -
    1. Charging Current (in mA/A)
    2. Battery Temp(in °C/F)

    Great reading. Not sure it is healthy for the battery to charge it faster at higher temps but kudos.
