I had an experience years ago that I got caught in a heavy rain while riding my motorbike. I was on an open road and there was nowhere to go to get out of the rain. My phone was in my pocket and it got soaking wet. I think I turned it off already.
Once I got home I removed the battery and wiped everything and left it on the table. (Never leave a wet electronic device under direct sunlight).
Three days after, I charged the battery using an external charger (the kind that you clip the battery to charge). I tried turning my phone on, it vibrated and died. It means there was still some water or moisture within the baoard that it drained the battery quickly.
A friend suggested to put it in a cotainer with rice. I left there for a few days. It did the trick.
As for back up... I think I will write an article about it soon. :)
a lot of cellphone parts are made of plastic including the board. Also, too much heat might have some adverse effects on electronic components.
I see. You're right. It can affect even on screen.
yup
