Google Maps usually uses the most power when its map stays visible and continuously redraws during navigation. GPS, location updates and cellular-radio communication add to the load, especially when mobile reception is weak. Google’s navigation guidance identifies screen rendering as the largest power category in mobile navigation apps, but there is no official, universal percentage for each Google Maps setting.
The safest battery reductions are to dim or briefly hide the screen when you can still navigate safely, limit Maps to foreground location access when you do not need background features, keep the phone cool and charge during long drives. Do not disable location during active turn-by-turn navigation: directions depend on it.
Which Google Maps settings use the most battery?
Battery drain during navigation comes from several systems working at once. The exact order and severity vary with your phone, display, signal strength, temperature, route and navigation mode, but Google’s developer guidance identifies the main categories.
The continuously visible map and screen rendering
Google states: “Screen rendering usually causes the highest power consumption in mobile navigation apps.” A moving map must redraw roads, labels, traffic, your position and the route while the display and graphics hardware remain active. A bright screen that stays on for an entire trip can therefore consume more energy than a map that is briefly checked and then hidden.

This is why reducing screen-on time is usually more effective than changing an obscure account setting. It does not mean you should operate a phone unsafely while driving. Set up the route before moving, use a proper mount and only lock or background the app when you can continue safely by voice prompts or another permitted method.
GPS and location updates
Maps needs a stream of location information to calculate your position, show movement and provide turn prompts. GPS and other location sensors consume power while they are active. More frequent updates can be necessary for precise navigation, so cutting location access during a route can make directions fail rather than provide a useful battery trade-off.
Cellular-radio communication and weak reception
Navigation can communicate over the cellular network to obtain or refresh map data, traffic information and other online features. Google notes that a phone navigating with poor cellular coverage can use more power than one near a base station because the radio works harder to maintain communication. A weak signal is not a Google Maps toggle you can fix in the app; downloading an area for offline use before a trip can reduce reliance on live data, but offline navigation still uses the screen, GPS and the phone’s other hardware.

Location sharing and other background activity
Location sharing and similar features can request location when Maps is not visibly open. Google identifies background location as necessary for some features, including Google Maps Location Sharing. If you do not use those features, reviewing Maps’ background permission is a reasonable way to reduce unnecessary work. The available documentation does not provide a fixed battery saving figure for removing it.
What can you safely change while navigating?
1. Reduce screen-on time without compromising safety
Google recommends locking the phone or putting the navigation app in the background as power-saving approaches. Do this only when you can still follow directions safely. Voice guidance, a vehicle display or a co-driver checking the route can make a hidden screen practical; if you need to see the next turn, leave the map visible.

2. Lower brightness or use an appropriate display mode
Lowering brightness reduces display power when the screen must remain on. Google’s Android guidance also mentions dark mode for OLED or AMOLED screens and adaptive brightness. Use the setting that keeps text and turns legible in your lighting; a screen that is too dim can create a safety problem and force you to keep it on longer.
3. Keep the phone cool
Heat affects navigation power use and performance. Avoid leaving the phone in direct sun, on a hot dashboard or under a case that traps heat while it is navigating and charging. Move it into shade and allow airflow around it. Cooling is a practical operating measure, not a Maps permission switch.
4. Charge during long sessions when necessary
Google lists in-vehicle charging as a way to handle heavy navigation use. A car charger does not make Maps consume less power; it supplies energy while the app is doing demanding work. Use a suitable charger and cable for your phone, and keep the device positioned so charging does not overheat it.
Android: limit Maps’ location access without breaking navigation
On Pixel documentation, the per-app controls are under Settings > Location > App location permissions. Other Android versions and manufacturers may use slightly different labels.
Use “Allow only while using the app” when background Maps is unnecessary
- Open Settings.
- Tap Location.
- Open App location permissions.
- Select Maps.
- Choose Allow only while using the app if you need location for navigation but do not rely on background Maps features.
“Allow only while using the app” makes location available while Maps is being used. It is more targeted than switching the phone’s entire location service off. Start navigation after granting this permission and verify that the blue position marker updates and turn prompts work.

When Android should retain background access
Keep a background-capable permission if you use a feature that needs Maps to obtain location when you are not actively looking at the app. Google specifically lists Location Sharing among features that can require background location. Removing the permission can stop or delay that feature. The correct choice depends on whether you use it, not on a guaranteed battery percentage.

Denying Maps location prevents it from using location, including while the app is in use. That can remove the position information required for turn-by-turn guidance. If you need to save power mid-trip, reduce the display load or charge the phone instead of cutting the sensor that navigation depends on.
iPhone: review Google Maps permissions in Location Services
Apple’s documented path is Settings > Privacy & Security > Location Services. From there, select Google Maps and review its access level.
Choose the narrowest permission that matches your use
- Open Settings.
- Tap Privacy & Security.
- Tap Location Services and make sure the service itself is enabled for navigation.
- Select Google Maps.
- Keep location available for active navigation; choose a foreground-limited option when you do not use background-dependent features and your iOS version offers that choice.
Apple explains that apps with While In Use access may ask to use location in the background. When background access is allowed, iOS periodically reminds you and shows those locations on a map. Review those reminders as a privacy and behavior check, not as proof of a specific battery saving.
Why turning off iPhone Location Services is a blunt fix
Turning off Location Services prevents apps from accessing location through that service and can limit the performance of various apps. It also prevents Google Maps from providing normal location-based navigation. Use the per-app control when your goal is to stop background Maps access; reserve the device-wide switch for situations where you intentionally want location disabled for many apps.

Should you turn off Location Accuracy, Wi‑Fi scanning or Bluetooth scanning?
Android Location Accuracy combines available Wi‑Fi access points, cell towers, GPS and device sensors to estimate location more quickly and accurately, particularly when GPS is obscured or unavailable. Wi‑Fi and Bluetooth scanning can provide additional signals for location.
The reviewed Google documentation does not establish that disabling Location Accuracy, Wi‑Fi scanning or Bluetooth scanning improves Maps battery life overall. Turning them off can reduce accuracy or alter location behavior, especially indoors, between tall buildings or when GPS reception is poor. Avoid a blanket battery recommendation. If you are troubleshooting, change one setting at a time, test the route you actually use and restore the setting if position updates become slower or less accurate.
Does Google Maps drain battery in the background?
It can, but “background” covers different situations. A route that continues while the screen is locked still needs location updates and may use radio resources. A permission that allows background location can support Location Sharing or another feature even when you are not viewing the map. Those activities are different from a dormant app that has no active navigation or background feature.
To diagnose your own phone, open its Battery settings and inspect Maps’ usage for the period in question. Compare the time Maps was on screen with the time it was allowed to run in the background, and note whether the phone had poor reception or was hot. This device-level record is more useful than applying a universal drain percentage, because Google has not published a setting-by-setting battery ranking for the consumer Maps app.

Google describes Timeline as an account setting that regularly saves precise location to a personal map when enabled, including when Google apps are not being used. Google says Timeline is off by default. Turning it off does not control location saved by other activity settings or by other Google products, so it is not a master location switch.

Google gives a frequency example: while you are using navigation in Google Maps, Timeline might be collected multiple times per minute; when the phone is inactive, collection might occur once every few hours. Those are descriptions of collection frequency, not measurements of battery consumption. They do not establish that Timeline is the largest user of power or that disabling it will cure Maps drain.
Turn Timeline off if you do not want that location history saved. Keep it on if you rely on the history feature. Make that choice for privacy and record-keeping rather than expecting a guaranteed battery improvement.
A safe setting plan for common situations
| Situation | Recommended change | What remains available |
|---|---|---|
| Active turn-by-turn navigation | Keep location permission; reduce brightness or hide the screen only when safe; keep the phone cool. | Position updates and directions continue while Maps can access location. |
| Navigation on a long drive | Use a vehicle charger if needed and avoid heat while charging. | Charging offsets consumption but does not reduce Maps’ power demand. |
| Maps is not being used and background features are unnecessary | Set Android Maps access to “Allow only while using the app,” or review Google Maps under iPhone Location Services. | Foreground navigation works when permission is granted; background-dependent features may stop. |
| You want to change location history | Review Timeline in your Google Account settings. | Timeline collection changes; other Google activity and app permissions are separate. |
| You have poor cellular reception | Expect higher radio demand; prepare map data before leaving coverage where practical. | GPS-based positioning still has its own power cost, and live features may be limited offline. |
Common mistakes and how to recover
Turning off all location before a trip
Symptom: Maps cannot establish or update your position. Fix: Re-enable device location, then grant Google Maps permission while the app is in use. Start navigation again and check that the position marker moves.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsRemoving background access and expecting every feature to continue
Symptom: Location Sharing or another background-dependent function stops updating. Fix: Restore the app’s background permission if you need that feature, or keep foreground-only access and accept that it works only while Maps is being used.
Disabling accuracy-related services for an unproven saving
Symptom: Position fixes take longer or become less precise. Fix: Re-enable Location Accuracy and any scanning option your phone uses, then test again. The available guidance does not promise a net battery benefit from disabling them.
Assuming Timeline is responsible for every battery spike
Symptom: Battery drain continues after Timeline is disabled. Fix: Check the phone’s Battery screen, screen-on time, reception, temperature and whether an active route or sharing session is running. Timeline is not documented as a universal Maps battery remedy.
The practical answer
Start with the screen: keep it dimmer and on for less time when doing so is safe. Next, remove background location only when you do not use features that require it. Keep location enabled for navigation, avoid overheating and charge during unusually long routes. Treat Timeline, Location Accuracy and scanning controls as privacy or accuracy decisions unless your own battery report shows a clear, repeatable effect.
