GPS trip tracking: battery use, accuracy and privacy explained

By the TripRank team · 26 October 2026 · 8 min read

Any GPS trip tracker asks for two things you value: your phone's battery and your location. This guide answers the three questions people ask most, honestly, and shows what you can do to get the best from tracking.

Does GPS tracking drain the battery?

Yes, somewhat. GPS and continuous background location use power, and a phone tracking a drive uses more than one sitting idle. How much depends on the phone, screen brightness, signal strength and how often the app samples your position. These habits reduce the impact:

• Plug in on long drives. A car charger fully offsets tracking for most phones.
• Leave the screen off. The display is usually the biggest drain. A good recorder keeps working with the screen off.
• Choose “allow while using”, or precise location, as the app recommends. Denying precision gives you worse routes.
• End trips when you arrive. A trip left running keeps using GPS for no reason. TripRank asks “Still driving?” if a trip has not moved for 20 minutes, and sends a reminder if your phone goes silent.

How accurate is a phone's GPS?

In open sky, a phone's GPS is typically accurate to a few metres. Accuracy drops between tall buildings, in tunnels, in parking structures and at the very start of a trip before the phone has a fix. Two common results are a short straight “jump” on the map and an absurd top speed for a second or two.

Good software handles it by:

• Ignoring a position that would require an impossible speed, rather than drawing a spike.
• Smoothing parked time so jitter at a red light is not read as movement.
• Separating a real flight from a glitch: a flight is many readings in a row at flight speed, while a glitch is a single wild reading.

TripRank does all three, which is why your driving score reflects your driving and not your phone's mood.

Who can see my location?

The right answer for a trip recorder is “nobody, unless you choose”. In TripRank:

• Location is used only while a trip is recording and a notification is showing.
• Other drivers see stats, such as name, level, ranks, distance and top speed, never your email, phone number or routes.
• If your username looks like a phone number, it is hidden behind a short code.
• A live-location link exists only if you create it, and it stops working when the trip ends.

The full details are in the privacy policy. You can ask us to delete your account and everything linked to it at any time via the contact page.

Android tips for reliable background tracking

• Allow notifications for the app, since the foreground service needs its notification to stay alive.
• If your phone aggressively kills background apps, exclude the app from battery optimisation.
• Start the trip before you set off and wait a few seconds for a GPS fix.

Checklist before you trust any tracker

1. It only tracks while a trip is running.
2. You can stop it and it fully stops.
3. Other users cannot see your routes.
4. It filters GPS glitches.
5. It has a clear privacy policy and a way to delete your data.
