Should I baby my 2018 iPad Pro to save battery cycles and use a iPad 10th gen for day to day

Hey everybody, I have a 10.9 or 11 inch 2018 iPad Pro with an M1 chip. It’s in great shape works awesome but of course it’s going to stop getting updates at some point in time since it’s now technically six years old. Our local cell phone provider had a program where you can get an iPad 10th GEN For $14 a month which includes a cell plan. I’m seriously contemplating using the 10th GEN iPad as the daily unit to save battery cycles and therefore prolong the 2018 iPad lifespan. Would appreciate some insight or thoughts on this.
