I kept stucking on OET at 100% and this phone is very intolerant of heat and frequent pausing...
I think I will stop working OET and wondering if there's the best optimal settings for this Xperia XA... |

The optimal is never suspending in BOINC settings. Of course this is not practical for how most people use a phone.
Maybe experiment with 1-8 cores to find a setting that doesn't cause a battery heat issue. |

I would leave it at 40C or possibly even lower. Keep a close watch on your battery temps. If it feels too hot on the back, that will reduce battery life on your device. I have had two devices blow batteries up from running boinc 100% 24/7. One device was not cooled in any way, just sat on my nightstand. Another was directly cooled by a 120MM computer fan blowing plenty of air over it. Felt cool to the touch, but after several months of crunching, I noticed the battery was ballooning out just as the other phone had. Using only half your resources might be a better bet, especially if it is your daily use phone. It will put less strain on your battery, and you will still be contributing. I just replaced the battery on my Nexus 9 since it was ballooning out. It had been running BOINC 100% on its 2 cores for about 6 months minus trips to and from work. 4 core nexus 7 hasn't had issues and it sits on my nightstand. Guess it depends on the battery manufacture. One was a Samsung S3, so the OEM battery had several years of "normal" service on it before becoming a cruncher. The other was a Motorola Droid Maxx with no easily removable battery. That one was tossed because I was afraid to try to open it up for fear of the battery. The S3 has a new battery now and BOINC is only running on 1 core. I purchased 3 of the refurb phones listed in the bang for the buck androids thread, and have them running 3 of 4 cores with a USB powered fan blowing air over them. So far, so good on those. I should just retrofit a minifridge to toss all my androids in, that way they will stay nice and cool  I understand that thing about the retrofit minifridge as a joke, but seriously: do you know if there is any such minifridge (but way smaller - like a nanofridge) just for cooling a smartphone at sale online? BTW, I've got this device called Thin Ice that produces cold (a vest supposed to make you thinner from the cold, but I believe it's a hoax for that purpose). I think it might be more effective than a good fan to keep anything cold, though. Would you try it out to keep your smartphone cool while boosting the CPU% or CPU core count on BOINC? If so, do you suggest me any particular tests (along with any software I might need to make them)? My smartphone is a Lenovo Vibe K5. Thanks for reading this! |

I use three Sony Xperias - all different models.
My first Sony Xperia E has just one processor and runs faithfully at 40 degrees C (the default setting) 100% CPU and 10% battery level - it could be zero as it is permanently connected to power. My second one Xperia M5 is my daily phone. It has a glued back cover that doesn't tolerate too much heat, so this one runs at 34 degrees C - and it is not very efficient, because it suspends all the time. However, a setting with fewer processors doesn't make it more efficient, as far as I can judge. I hook it up to power when I find it's >50%, otherwise it just lies there, because it's my impression that charging heats the battery. My third one Xperia L has four processors and a sturdy backcover. It runs happily on all four at 40 degrees C. I also have a Lenovo tablet. Same thing. They all have names: Mr Jones, Saphir12-Nathalie, D, mike - it's a girl thing  |

I have many ARM/Android devices running with all cores possible, but I stablished a 30 Celsius limit on temperatures. It will redice the risk of danger in bateries.
Be aware that I burned literally two bateries in devices running over 33 celsius (Lenovo K8 note 10 cores and Motorola G5 Plus 8 cores). Good luck      |

Sorry for the late reply; I am not on WCG much anymore and rarely check in. I have seen small fridges for 6 packs of beverages that can plug in to a wall socket or a car 12v outlet. You could always make your own cooling device out of a peltier system. With the peltier system you could make your "fridge" as large or as small as you want. |
