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

Smartphone GPS is usually accurate to within a few metres under open sky, but mountains, cliffs and other obstructions can block or reflect satellite signals and reduce accuracy. Offline mapping may still work without mobile coverage, but treat the displayed position as an aid rather than a guarantee.

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

Start fully charged, keep the phone warm and protected in an inside pocket, minimise screen use and carry a charged power bank. Download maps before leaving so you can navigate offline, and preserve enough battery for emergency communication.

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

Yes, especially in hill or mountain terrain. A paper map and magnetic compass do not need batteries, but keep the map dry, learn how to use both and keep the compass away from phones, magnets and metal that can affect its reading.

Should You Trust Your Phone?

Phones provide GPS positioning, detailed maps and emergency contact, but batteries can drain faster in cold weather, screens can be hard to read in bright sun and mobile coverage often disappears in valleys. Knowing when phone navigation suffices and when it doesn't prevents dangerous overreliance.
