    OK, so I have an S7, but it's only about 2 years old.

    The battery is discharging faster and faster, so I'm pretty sure it's time for a replacement.

    I use a wireless USB charging cradle. Sometimes I've left the phone on there after the charge had reached 100%. I'm sure that's had something to do with the battery failing.

    Is there a "smart" USB wireless cradle charger, or is that a feature only available in newer phones?

    It's the S7 itself that determines when charging is 100%. Basically when the front LED goes green, and the display shows 100%, charging is complete and the phone itself stops charging the battery, and won't overcharge even with the charging still connected.

    Qi compatible wireless charging pads and cradles, determine if a device has been placed on them and the correct amount of power to supply to the device. But there's no way for them to determine the amount of charge in a device's battery AFAIK.

    2 years for a phone battery? It all depends on how much the phone has been used of course, and YMMV. I've got a S7 here that was used daily for a year, and now very occasionally, and the battery is still good in it. Also I have a Huawei Mate10, that was used heavily for over 3 years. and the it's showing a permanent "Battery health is deteriorating" notification warning now, however I never noticed any increased discharge with it. I probably will get the Huawei battery changed, because I still use that phone as a remote control zapper for TV, Android Box and the air-con. And it no longer has a SIM in it.
