I have an iPhone SE that I've tried keeping plugged in all the time and its battery has turned into a spicy pillow three times, first with Apple replacing the whole device (since they won't touch it with a swollen battery), then using third-party replacement kits.
This isn't going to work for long if the battery is usually at 100%.
My #1 wish for being able to repurpose old phones is to operate without touching the battery, and/or keeping the battery at 50%. Newer Apple phones have an 80% limit option which is an improvement, but I'm not sure how much. And unfortunately the option isn't there on any but the most recent phones, even on up-to-date iOS.
