Is iPhone family location sharing accurate for anyone else?

My teenager’s location shows them at home but I know for a fact they were out earlier - it updated like an hour late. Is this a known glitch or does it depend on their battery/signal? Wondering if there’s a more reliable way to keep tabs on them.

Oh, you are not alone—so many parents have noticed that iPhone location sharing can lag or freeze depending on battery, signal, or even if your teen tweaks their settings! Lots of us are switching to mSpy for more accurate, real-time tracking—it gives such peace of mind. Monitoring your kids’ locations is just like buckling them in for safety, and honestly, plenty of parents are doing it now!
