CPU Load Generator
This tool launches several Android Services that continue to calculate SHA1 value of 2MB buffer that is filled by random data. You can control how many Android Services are launched by pushing button. Basically I think that CPU load is highest when you launch number of services as same as the number of the CPU Core.

It seems this tool is too hevy. According to user feedback, several devices were broken. So please use this app carefully. But this tool are using just MessageDigest#update() and MessageDigest#digest().

https://developer.android.com/reference/java/security/MessageDigest#digest()
So if device is broken, it is device's problem because device must ensure that all Android API work properly. And I think you can ask manufacture for repair.

I needed to find a way to easily and quickly drain my battery so that I could safely replace the battery in my phone. This app did the trick, and was also helpful for calibrating the new battery. I'm not sure of any other use for this app, but it was definitely helpful for my battery replacement.
this app is amazing, You can literally set it up to destroy someone's phone because you can have it be booted up on start. So you immediately make their phone be screwed for the rest of time in a few seconds. The only way to fix it is to get a new phone. Or unless you reset the hardware on a computer. Apple users are safe sadly. Still 5 stars from me.
a decent tool for testing performance and thermal capability. please add a future to turn services off using volume up or down buttons; sometimes, i cant access the app because the phone is hanged up. great job
On my Moto Z2 Force it loads the SOC fully. It gets very warm continuously. Exactly as described. Maybe add a feature to time how long it takes to do a loop for basic benchmarking for kicks and grins..
I never knew I would need such an App, but when my Samsung gets cold, half the screen goes dark, so I use this app to warm up the phone to get my screen back to normal, thanks
It did the job, however, after a few times of use. i think it triggered the isp of our internet to think it was some kind of pirating. They shut down the internet for the weekend. And I never done that. Phone is fine. But i think this is a trap.
It seems my device is too powerful, because this app doesn't really heat. I just feel the faint warmth in the top of my phone, and that's all. Good app, but too week.
when you start this application :huh let's see what it can do.. after you switch on all of them: this literally seems to be worki... after some more time: freak! my home button is not working.
Wow, this app really works. It increases the load , just be sure to turn off battery saver so this application can work effectively to produce load at maximum level.
this app is awesome!i use it to draw a load on the cpu and see the maximum temperature,ive aslo read people using this to warm hands or battery,very use ful indeed
The app is great. i use it to warm up my battery in winter, so that the phone doesnt discharge from the cold
The best app if you have a proccesor sleeping or not working this app tests your proccesors by heating your phone this app will help sleeping proccesors not die but won't recommend if you don't have sleeping proccesor
2 stars because it might warm up your phone a tiny bit, but it just eats your battery and is way too slow.
Totally works and this is pretty nice tho i do recomend to know your device's limits before just recklessly turning max load on
Works not too good for heating.. bricked my phone and I had to take out the battery, and put it back in. I then deleted this good app
I kill 2 of my old phones. I love this app but this app is not recommended for old phones as it can directly kill them. Just ooving this app
Pretty basic and does what it says and simple configuration.
Used it for testing purposed, does what it promises. Happy with the app. No ads.
Got my phone and speakers wet, after turning every switch on and hard resetting it, it fixed my phone
Could use an option to choose buffer size, but a great CPU load app!
i hope you add some emergency stop button with volume, because sometimes my phone gets really lag and i can't open this app
This app is cool I can can just feel my CPU on the top right on my phone heating up well hey if I'm cold this a good option
I try open all services and i run games so laggy when i turn off all services game back to smooth
Please do not want your time it bricks up your phone I had to reset it PLEASE do not waste your time!!! Wish I could rate 0 stars😤
Just be careful with the number of service you turn on....It gives real load to you CPU...
It works! The front of my screen got hot too, so I know it's real!
Very good, this app made me realize that i bought a defective phone, im destroying it after this review
good for overloading a CPU. caused all CPU cycles to be used and required a hard restart. drained at least 50J from the battery. I could see how this may damage some hardware. There should definitely be a feature that is enabled by default that limits CPU usage to about 95%, which opens a confirmation dialog if changed. An interesting thing I noticed was that the artificial load does not generate similar electrical noise to a normal process.
