Get a fairphone and remove the battery. As long as the phone is connected to the PC and is getting electricity, it will work without a battery like PCs.
Some phones have a setting that limits charge to 80% or another non-100% number. Maybe that would help?
I know several manufacturers that include some form of this feature, Google Samsung, Sony. On Sony it's called Battery Care.
Google does not include this setting.
"testing of apps".
Why, what's he actually up to?
Scam reviews or bot account creation would be my guess
Oh thank god, I thought he was watching like 20 p*rn streams at once.
It's possible to do some form of crypto mining with phones/tablets. Maybe that.
Mining on phones? God forbid.
Seems like there's some crypto called Verus Coin that can be mined on phones.
So some people have racks like this:
Samsung phones have a battery protection mode that will stop charging at 85% when enabled. Any lithium pouch cells will swell up if they are kept on a charger at 100% continuously.
You can use wireless ADB, or try to set the battery limit to 80% and only set charging to only start below 30%. Wireless ADB settings can be found in the developer options. battery options don't always include the option to require battery level to drop below X% before charging starts again, and if it is, it is usually branded as battery saver feature or smth like that.
Phone battery can be changed though, could save you a lot of money that way. Or use fairphone, it can be easily swapped in second.

Not an android user or anything, but I would assume there are apps to disable charging the battery. Or apps to allow you to use a phone without the battery.
If you can disable charging then I’d discharge to 20% or so then disable charging and connect it. 20% should be a fairly safe storage capacity for the battery. Maybe 30-40 to be on a bit safer side.
Then you could just go through a battery cycle once a month or so to ensure different cells get used. I’m sure you could figure out an automation for that mr tester man.
Any app I've found that can do this requires rooting. Some ROMs include this by default.
Get a phone with a removeable battery, such as the aforementioned Fairphone.
Could you use a data only USB cable and only charge when needed?
This is a most excellent place for technology news and articles.
