    I am observing my 3T device's battery draining very fast. Software version is 9.0.6. I have checked some available tips but not worked well. Battery health is about 82%. So it's quite healthy still. Something else creating problem.
    Please suggest. Thanks. Asim.

    Please check battery health. I have verified it from service center. if it's above 80%then battery health of your device quite good.

    i think oneplus avoids the phone to get to 100% to avoid the battery to overcharge and makes the battery bad overtime, so they show 100% but the charge stops if its 97%.

    idk, same thing happens to me.

    to fix this, you have to calibrate your phone.

    Let the battery completely discharge, plug in the charger with it switch off, charge to 100%, switch phone back on, the battery should now be calibrated.

    I have a few Oneplus phones, a 5t a 7T and my trusty old oneplus 3T, one thing I have noticed though with my oneplus 3T is that when downloading any updates to apps or to the system the battery percentage goes down extra quick....my battery health is close to 87 percent, so it is not a battery issue...I read above about calibrating my battery, but strangely the issue only seems to happen when doing updates, I tend to only update on Wifi, so it is not the mobile data used.

    Currently using the latest update available for the phone.

    Has anyone installed one of those chinese 4000mah batteries? I had 70% at 7 am and by 9 am, just using it at the gym with mp3 and some chatting it drained the entire battery. Anything else I can do?

    Try to get oem battery (and really new one). You may have luck with these Chinese ones but hard to say which one is good and which one is bad. You're lucky your phone didn't catch fire.
