S8's will throttle down if they are not cooled. I use a laptop cooler with a thermometer: Thermaltake Massive TM. I cool 3 S8's and an S7. The four thermometers read a case temp of 65 to 70 degrees F at 100% CPU and 100% RAM 24/7 ambient temp < 75 F. Looking at CPU system monitor I see CPU usage drops down below 30%. Stopping the boinc app from applications and restarting it fixes the issue. Clock speeds don't seem to be effected for me when optimal usage at 100% however I only have ram set to 80%. Also ambient temp is around 70 if not a little cooler. Is quick charging effected by boinc? That is to say if 100% cpu will charging still be slower or is it smart enough to take more current from the wall socket to achieve maximum charging speed? Or am I thinking of oneplus phones?

I have the same problems with my Galaxy S7. When I change the perferences to 8 cores, CPU utilization in CPU-Z is ~40% and 2 cores are completely stopped. The elapsed workunit run time is extremly long, but without much CPU time. So I changed my preferences to 2 cores, instead. The WUs have normal run times now, but this couldn't be a solution. I would like to utilize all cores.
This doesn't seem to be a WCG problem. I just tested this with SETI WUs and I had the same result on my S7. I also had this problem on my old Nexus 5X, Nexus 6P and Nexus 5. One day after an update of the Boinc app, it worked on my Nexus 5. I suspect it has something to do with the Android version. |

Do you cool your case i.e. a laptop cooler? The CPU will run hot very quickly and throttle down to prevent thermal damage at high loads. A laptop cooler fixed that issue for my S7's and S8's. WCG only offers 4 cores on my S7's. How can I get 8? I did something wrong somewhere.

I found that if I remove my phones from laptop cooler for not very long it will overheat again and require a reboot. I get around this problem by suspending all 8 cores until I'm ready to return it to the laptop cooler. DEscribe your cooling method? Does it have a metal mesh cooled by a fan which cools the metal?

I found that every time I lift my phone off my laptop cooler, it doesn't take long to overheat past the temperature threshold. I get around this issue by remembering to suspend BOINC while it is not being cooled and resume once it is back on the cooler. My laptop cooler has a metal mesh cooled by a fan from the bottom. Is your setup sufficient to produce that level of cooling. Note: If a reboot is required, ensure it is cool first.

Hm, I don't cool it at all. But CPU-Z says that all thermal zones are under 45°C.
----------------------------------------You might have the US version of the S7? Samsung put a Snapdragon quad-core CPU inside. In Europe they put the Exynos 8-core CPU in the device. [Edit 1 times, last edit by Lieutenant Wurst at Oct 28, 2017 12:16:11 PM] |

That's the setting that could be activated in BOINC on your phone. [Edit 1 times, last edit by SekeRob* at Oct 26, 2017 9:10:55 AM] |

Mine seems to happen when I plug the phone in after it is suspended on battery power. It fails to resume unless I go to settings, apps, boinc, force stop and then start again.
----------------------------------------Very frustrating but is a workaround for now...

Was just hoping there might be a fix for this
----------------------------------------S6 all cores flat out as allowed by the heat it generates.. nice and toasty loads of result S8 4 ARM A53 cores flat out - all 4 Exynos M1 running at lowest clock speed battery life great but not as much research being done as I had hoped Dave ![]() |

I know this is an old thread, but seems to happen to my s8 plus as well. Some of the tasks that are only 6 hours on my LG4 runs for 12 to 25 hours on my S8+. Tried several steps listed here (restart, uninstall and re-install of boinc app), but seems to be the same.
----------------------------------------If anyone has any new insights I would greatly appreciate it. ![]() |
