I have a Samsung Galaxy A71, with a Snapdragon 731 on Android 10.
----------------------------------------It uses 2 big cores, and 6 small cores. Most projects run the small cores. Battery temp would normally reach about 30-33C under 6 thread operation. I've noticed that World Community Grid made my phone a lot hotter, and CPU-Z showed that the big cores were at 75% continuously. Battery temps rose close to 40C, and the screen and the back of the phone were hot to the touch. Rosetta tends to heat up the phone more than other projects, but it never manages to get the big cores spooled up, and temps generally stay below 35C (which is still acceptable). I'm just wondering if something is misconfigured? I have temporarily paused processing WCG data for the moment. Thanks! [Edit 1 times, last edit by ProDigit at Oct 6, 2020 2:18:48 AM] |

In the client, under Preferences, there's a CPU section where you can select how many CPU cores to use.

You can set the battery temp max in the Android BOINC client. I've got it at 35C. If I forget pause before leaving house and it gets cozy in the trouser pocket, BOINC will just stop and show "waiting to cool down". You have to tick the 'Show advanced preferences' box to see those options, but think you already have.

Both solutions are not feasible.
To select 4 out of my 8 cores (2 big, 6 little), it still uses the big cores. To get the temperature at bay, I'd have to reduce my 6 WUs to 2 or 3. I'm using this phone to crunch on other projects as well (Rosetta, and a few others), and they keep their tasks to the little cores. Also setting temperature maximums to use the big cores isn't good at all. It'll continuously strain the battery, and turn cores on and off, which in turn uses more power, and lowers performance. Until wcg fixes this issue for android devices, I will disconnect the project from that phone. |

Still no solution?
