Hello Everyone,

It seems like my phone is having this issue for a long time. I started noticing it after installing latest stock Oreo rom rooted version from this page
(https://forum.xda-developers.com/v20/development/stock-rom-lg-v20-h990ds-h990ds20a-idn-t3890697)
My phone always seem to die at 20% battery. I have tried replacing battery many times but it doesn't seem to work. Is there any chance it may be this custom kernal's issue/misbehaving or is my phone's motherboard faulty. ? Is there anyone else facing same issue ? Please help

I had the same problem it is most of the time the battery that starts to degrade and when it hits 20 per cent has way too little voltage to keep the phone running. Try going back to full stock no root on nougat not oreo then root it again and try installing another H990DS rom I am using the stock flashable oreo I forgot the link but it is the Indian variant

Thank you friend for replying. I will try flashing stock nougat today or tomorrow using lgup tool and let you know. So just one question, did your issue of phone shutting down at 20% got resolved by changing battery or flashing stock oreo ?

Also this is what accubattery shows. It never shows battery capacity as 3200 mah and my phone always dies at 20% battery. I tried 7 different oem batteries,same results

In my experience, never use OEM battery. most of the time those are 2000mah crap.
so, in my opinion, better get unofficial 3200mah or 4100mah or larger battery from reputable battery company on your country or import perfine/shenmz/other reputable ones (look on lgv20 subreddit for more info if importing) if possible.

My problem was solved by chnaging the battery
