Any app that checks location during an active journey can use additional battery. The useful question is whether that cost is responsible, predictable, and justified by a timely alert.
Why the app cannot simply stop checking
MetroPing needs enough location updates to estimate progress before the selected destination or interchange. Checking too little may save power but make the reminder late.
Checking too often can improve responsiveness while using more energy. Finding the right balance is an engineering trade-off, not a one-time switch.
Why battery use differs between journeys
Signal quality, journey length, background restrictions, phone model, operating-system version, and manufacturer power management can all change the result.
That is why one tester's battery experience cannot reliably predict every other device.
What feedback helps most
A useful battery report includes the phone model, operating-system version, approximate journey length, whether the screen was mostly locked, and the battery level before and after.
Those details make it easier to distinguish a repeatable problem from normal variation and to test a targeted improvement.
Check too often and battery suffers. Check too little and timing suffers.
Battery optimisation and station accuracy are being improved together because neither can be treated as an afterthought.
