Help Running phone without battery

Nothing about erasing data on the phone, but I have a tangential issue where I want to power and use a phone without its battery.
Got a few old phones and want to try to re purpose them. Batteries are old.
I can only seem to get them to boot up when the batteries are in them and a charging cable is plugged in.
I looked at the batteries and see that they both supply 3.7v whereby USB charging is at 5v
Seems the batteries are required to run the phones even if you plan to always have them tethered. Which brings me the the point:
At some point in time, the battery will no longer even be able to perform its sigular remaing task being; to regulate the voltage from 5v input to 3.7v output.
Anyone had any luck in hacking a bypass that replaces this final function of the battery? for example installing a voltage regulator in place of the battery?
