Most high-quality LiPo-powered devices already do this at the hardware-level. The 100% level you see on the software is usually 80% actual charge on the battery.
For Android, there are a multitude of apps, such as Wattz that will tell you the actual voltage of the battery. Full may be 4.2V or 4.35V depending on the chemistry used. ACCA (root required) will let you limit charge rates and stop charging at a certain percentage.
Staying under 4 volts (around 60% for most phone batteries) will vastly extend battery service life. 80% is a bit less extension, but still far better than charging to 100%.

Any way to tell? I just got a monster phone with a 22K mAh battery.

My phone is at 57% and Watzz says 3.9V, that doesn’t seem good lol
