    I am using OnePlus 7T Oxygen OS 10.3.2.HD65AA.
    Indian ROM

    Using a Jio Sim in slot 1 and Vodafone in slot 2

    even though all my calling is through the Sim 2 and my data is set to Sim 1 as soon as I receive or connect a call my data switches off both sims.
    Is this a software glitch or is it something that's part of the OS.
    using 4G sims in both the slots

    The battery is abysmal. single charge upto 95-98 % works 4-5 hrs. I have to run phone on battery saver mode after I charge to extend battery life also I am using 60 ref rate instead 90, I am using a black screen saver and dark mode.

    I am a doctor so it's impossible to carry the charger cable everywhere. And also face ridicule from all my friend and family who give me the told you so look.

    please help...

    I can't afford to start a consultation and then disconnect to see images and reports from patients .
