    I have OnePlus 3t. It was running fine till now then suddenly it started getting random shutdown irrespective of battery percentage (i.e it may get shutdown at 70% or 94%), then after applying charger and then powering ON, it will power ON, without applying charger it will not open, I have tried factory reset many times but nothing fine.

    Welcome to Android Central! The battery might be failing. After it shuts down and then you plug it in to charge, what battery level does it read when you power it back on? Is it still at the same level as when it shut down, or is it all the way near zero?

    No it will remain where it was left.
    And most often shutdown will occur if I press recent app button. Otherwise it will run good.

    Then I would suspect the battery, but you'll have to get it checked by a repair center

    Yeah, it's either the battery or some other hardware issue. Back up all of your important data NOW in case the phone fails completely.

    I think these happened because I removed the Google account and added. Then after next day it happened. It seems Google is doing all these stuff.
    Also now I was watching a movie on YouTube for around 90 mins then suddenly home button got pressed and it shutdown again.

    You mean you went to Settings>Accounts, removed your Google account there, then added it back again? Or was it not originally your account? Is there a reason you had to do this?

    It was my account, but to reset password of my friends account I removed my account and added my friends account and reset it's password, then removed my friends account, and added my account again. That what I did.

    Hmm, kind of an odd sequence, but I still doubt this would cause the phone to shut down randomly.

    Just to be clear -- you said that this still happens in Safe Mode, correct? If so, then you may want to try reinstalling the stock firmware, in case the current firmware has become corrupt for some reason: https://www.getdroidtips.com/oneplus...e-collections/

    Does installing firmware means installing whole rom, as in the link the file size is 1.5gb. and using that method I may not get bricked right?

    Is this orginal battery?

    Flashing stock rom i would go with the guidelines of xda forums or one plus community app, I've done it on my 1+7p that was tmobile version to global unlock version. It was nerve wrecking lol because I'm use to Samsung flashing firmwares and know it well to get out of a jam with one plus I had to do lot of research and my basic knowledge how to go about it.

    Inspect the battery contacts and insert pins. Clean with a Q tip and isopropyl alcohol. Never touch them with your fingers.
    Try a known good cable and charger. A cable can fail to charge but seem to connect normally.

    If the battery's lived a long life... they don't live forever.
