How much battery does live location sharing use?
It varies a lot, and there's no single honest number. The biggest drains during live sharing are GPS running for a long time, a screen that stays on, and a weak signal that makes the phone search for a network. Apple lists low signal as a battery drain, and Google advises avoiding long GPS use to save battery. A one hour run on a well-charged phone is rarely a problem; a long hike in poor coverage can be.
How to keep sharing without running out of battery
01Start with a full charge
This matters more than any setting. Leaving home at full charge gives you room for GPS, a few photos and an emergency call. If you're heading out for several hours, carry a small battery pack and a short cable.
02Let the screen turn off when you can
A lit screen is one of the biggest drains on any phone. Many native apps can share location with the screen off. Some browser-based tools need the page open and the screen on to keep sending updates, which uses more battery, so check how your tool works before a long outing.
03Watch out for weak signal
Apple notes that when you're in poor coverage your device searches for a better signal, which uses battery. On remote trails, the phone can drain faster than usual even if you barely touch it. Plan for that on long hikes and rides.
04Be careful with battery saver modes
Google says Battery Saver limits or turns off background activity, and some apps may be delayed. That can slow or pause live location updates. If you turn on a saver mode mid-run, expect less frequent updates and tell your contact.
05Cut other drains, not the safety app
Streaming music, navigation with the screen on and camera use all compete for battery. Download playlists before you leave, close apps you don't need, and keep the phone warm in cold weather, since cold batteries drain faster.
06Measure your own phone once
Battery use depends on your phone's age, the app and your signal, so measure it. Note your battery percentage, share for a 30 minute run with the screen as you'd normally use it, and check again. Multiply for your longest planned outing, and keep at least a quarter of the battery spare for calls and navigation.

What happens if my battery dies while I'm sharing?
Updates stop, and most services keep showing your last known location. That's still valuable to someone looking for you. A return time helps even more: with Holler, if you haven't checked in five minutes after it, your Guardians get an overdue alert from Holler's server even if your phone is dead.
Does the person watching my location use much battery?
Not much. Watching a map uses about as much as any other web page or app while it's open. They can close it and rely on alerts instead of watching the whole time.
Is it better to share or to save battery for an emergency call?
On a normal run or ride, you can do both. On long trips with poor signal, keep a reserve: carry a battery pack, and if you're getting low, message your contact your position and plan before you switch things off. Our guide on how to carry your phone while running covers keeping it safe and warm, and what to do when you lose cell service hiking covers the backcountry case.
