How reliable is my phone’s GPS when I’m out in the mountains?

It’s usually accurate in open sky, but in valleys or near cliffs the signal can bounce and give you a location that’s off by metres or even show you in a lake. Treat it as a guide, not a guarantee.

What’s the best way to keep my phone battery from dying in cold weather?

Keep the phone close to your body in an inside pocket and bring a portable power bank. Warmth slows the battery drain, and a backup pack gives you extra charge if the phone gets cold.

Should I still carry a paper map and compass even though I have a smartphone?

Yes – phones can fail from dead batteries, water, or GPS errors, while a paper map and compass work in any weather and need no power. Knowing how to use them gives you a safety net.
