Will Leaving Location On Drain Battery? Facts

Leaving location services on does drain battery, but the impact is usually modest—typically 1% to 5% of daily battery life on modern smartphones. The exact cost depends on which apps use location, how often they request it, and whether you use high-accuracy GPS or battery-saving modes.

Formula

Location drain (percent of battery) = (GPS current draw in mA × screen-on time in hours) ÷ (battery capacity in mAh ÷ 100).

Variables:

• t = screen-on time (hours) – the time the phone is actively used with location on.
• b = battery capacity (mAh) – total charge the battery can hold.
• g = average current draw from GPS (mA) – typically 30–60 mA for continuous GPS, but much lower for passive updates.

Worked Example

Using the default values: screen-on time = 6 hours, battery capacity = 4000 mAh, GPS current draw = 30 mA.

Step 1: Multiply GPS current by hours: 30 mA × 6 h = 180 mAh.

Step 2: Divide by battery capacity: 180 mAh ÷ 4000 mAh = 0.045.

Step 3: Convert to percent: 0.045 × 100 = 4.5%.

So with 6 hours of screen-on time and continuous GPS, location uses about 4.5% of a 4000 mAh battery.

How Location Services Actually Work

Your phone determines location using three main methods, each with different battery costs:

• GPS – Uses satellites, most accurate but also most power-hungry (30–60 mA). It takes a few seconds to lock and uses more power when the signal is weak, like indoors or in dense cities.
• Wi-Fi positioning – Scans nearby Wi-Fi networks, even if you’re not connected. Uses much less power than GPS (a few mA) and works indoors.
• Cellular network – Estimates location from cell towers. Least accurate but also least battery drain.

Modern phones combine these methods. For example, a mapping app might use GPS for turn-by-turn directions, but a weather app might only check your city-level location once per hour using cell towers. The battery cost varies hugely based on which method is used and how often.

Which Apps Drain the Most

Not all location usage is equal. Apps that continuously track your movement in the background, like fitness trackers, navigation, or ride-hailing apps, drain more. Apps that only use location when open, like a camera app tagging photos, have a negligible impact.

You can check which apps are using location in your phone’s settings – usually under Settings → Privacy → Location Services (iPhone) or Settings → Location (Android). Look for apps with “Alwaysâ€� or “While Usingâ€� permission. “Alwaysâ€� means the app can access location even in the background, which can add up.

For example, a navigation app running in the background for an hour might use 30–60 mA, while a weather app checking once an hour might use less than 1 mA per check. The difference is a factor of 50 or more.

How to Reduce Location Battery Drain

You don’t need to turn location off entirely. Instead, try these steps:

1. Change app permissions – Set apps to “While Usingâ€� instead of “Alwaysâ€� when you don’t need background tracking.
2. Turn off precise location – On both iOS and Android, you can disable “Precise Location� for apps that only need a general area, like weather or news.
3. Use battery saver mode – Many phones have a “Battery Saving� location mode that uses Wi-Fi and cellular instead of GPS. You lose some accuracy but save power.
4. Close navigation apps – When you arrive, close the app completely. Some apps keep GPS running in the background if you don’t.
5. Disable location for system services – On iPhone, you can turn off “System Servicesâ€� like “Popular Near Meâ€� or “Location-Based Alertsâ€� that you don’t use.

Common Misconceptions

Many people believe that simply having the location icon in the status bar means heavy battery drain. That icon appears whenever any app accesses location, even for a split second. A brief flash is harmless; it’s the continuous or frequent use that matters.

Another myth is that turning off location saves huge battery life. In typical usage, the savings are small – often less than 5% per day. The biggest battery drains are usually the screen, cellular data, and apps running in the background, not location itself.

Also, note that “Locationâ€� is not the same as “Bluetoothâ€� or “Wi-Fi.â€� Turning off location doesn’t disable those radios. However, on some phones, Wi-Fi scanning for location may still occur even when Wi-Fi is off, unless you disable “Wi-Fi scanningâ€� in location settings.

Comparing Location Modes

Here’s a rough comparison of battery usage for different location methods (relative, not absolute):

• GPS only – Highest drain, most accurate (within 5–10 meters).
• Wi-Fi + cellular – Medium drain, accurate to about 20–50 meters.
• Cellular only – Lowest drain, accurate to 100–1000 meters.

Modern phones often use a mix. For example, when you’re moving fast (in a car), the phone may use GPS more; when you’re stationary, it may switch to Wi-Fi. The “Battery Savingâ€� mode on Android and “Reduce Accuracyâ€� on iOS force the phone to avoid GPS.

Frequently Asked Questions

Does turning off location save a lot of battery?

Usually not a lot. For most people, turning off location entirely saves only 1–5% of battery per day. The screen and apps running in the background are far bigger drains. However, if you use navigation or fitness tracking for hours, the savings can be more significant.

Why does my location icon appear randomly?

Apps or system services may check your location periodically. For example, a weather app might update every hour, or your phone might use location for “Find Myâ€� or emergency services. A brief icon appearance is normal and doesn’t mean heavy drain.

Does using GPS in airplane mode drain more battery?

In airplane mode, radios are off, but GPS can still work if the phone allows it. However, without cellular or Wi-Fi, the phone may rely more on GPS, which can drain more. Also, GPS needs to download satellite data, which may be slower without a network connection.

Is it better to turn off location or use battery saver mode?

Battery saver mode is usually better because it keeps basic location functionality while reducing drain. Turning off location entirely can break features like maps, weather, and photo tagging. If you don’t need location at all, turning it off is fine, but for most users, battery saver is a good compromise.

Does leaving location on affect battery health over time?

No. Location usage affects battery charge cycles, not battery health directly. Battery health degrades with charge cycles and heat, not with specific features. However, using location heavily may cause your phone to heat up, which can slightly accelerate aging, but the effect is minimal.
