I have never seen such a thing, probably because this sort of thing is supposed to be completely automatic.
If only there was a way to change maximum charge voltage, as cycle life depends mostly on charging and discharge voltages:
Generally if Li-Ion is charged to 4.2v, cycle life will be well over 600 charges to 80%.
If charged to 4.25v this drops to 400 charges
If charged to 4.30v this drops to 200 charges.
If charged to 4.35v this drops to 125 charges.
Typical life is considered to be to 80% capacity, which means the permanent loss of 20%. However Li-Ion could be described as aging gracefully, because even at 50% of new capacity it is still very useful. Well, if it doesn't swell up.
Especially cell phones are often too aggressive with the charging, leading to a battery that may only last about a year before it's down to half the original runtime. This isn't as much of a problem if the battery is easily replaceable.
The safety disconnect is also too low, usually around 2.5v. This causes damage each time it is discharged until shutoff.
