iphone 5, replaced cracked screen and battery, since then very poor gps tracking in maps and google maps . looks like it is only using cell triangulation . is there a way to actually see signal strength ( app?) possible common issues/ start points to look for ? wifi signal is good and cellular is good as well

I would guess try resetting your cellular settings, or just do a reset. If other things are working it almost doesn’t sound like there’s a hardware issue
