RE: An easy, but very helpful tip : If you have an old phone you no longer use crunching GRC, remove the casing to improve cooling, and with that, perfomance.

I'm also using two Galaxy S3 to crunch.
Do you know if there's a way to also remove the battery? By connecting the phones power directly with an usb charger or so?

It depends on the phone, some work just fine if you remove the battery while they are on, some can be made to run like that just by moving the pins that run to the input of the battery to the output of the battery, some can be made with a small soldering, and some are not able to be modded.

Thats the good thing about popular phone models :)
