Mi5 Goes Off And Won't Turn Back On

Oct 1, 2015
Hi everyone,

I got a Mi5 which has an issue since a few weeks. In my pocket, it goes off and won't turn on again. Charging or pressing the power button for a long time have no effect (the LED doesn't even bright up while connecter to charger, but it still seems to charge).
I have to disconnect/reconnect the battery to start it again.
If I let it sit on a table or something, no issue at all. I let it unused for 3 days without this crash. In my pocket, it gets faulty within a few minutes.
I also tried a full reset, and clean install of the latest xiaomi.eu rom, no luck.
My guess would be the sweaty/moist environnement of a pocket cause this issue maybe?

Do you have any advice on what could cause the issue? Maybe it's a known issue with a specific component?
I'm tech-savvy, so I don't mind getting my hands dirty.

Thank you fou any advice you could give me.

Hi guys. Disconnet battery, and TRY switch on! (HOLD the button) for minimum 10sec, then reconnect battery and charge as normal, after 2-3min your Mi5 should start as normal. :)
