Battery & Data Usage for Guard Shifts
What This Page Answers
When you roll out MyProtektor across your guard team, you need to know how the app affects the devices your guards carry. This guide covers the three questions that come up most often:
- How much battery does the app use during a shift?
- How much mobile data does each guard need?
- What should I tell my guards about keeping the app running?
The figures below are based on real-device measurements during active duty. They represent typical ranges, actual consumption varies by device model, network conditions, and how busy the shift is.
Typical Usage Per Shift
These figures cover normal guard duties, location tracking in the background, filing incident reports with photos, scanning QR patrol points, responding to assignments, and checking the dashboard throughout the shift.
| 8-hour shift | 12-hour shift | |
|---|---|---|
| Battery | 5–8% of a standard smartphone (4000 mAh+) | 8–12% |
| Mobile data | 10–30 MB | 15–45 MB |
A quiet night shift with few incidents sits at the low end of these ranges. A busy daytime shift with multiple incident reports and photo uploads sits at the high end. Either way, a guard's phone will last an entire shift without charging, and the data usage stays well within what basic prepaid SIM packages provide.
What uses the most data: incident reports with photos. Location tracking, QR scans, assignments, and push notifications are all very small. If a guard files several reports with multiple photos each, that is where the data adds up, but even a busy shift stays under 30 MB.
How MyProtektor Keeps Consumption Low
GPS tracking features described here require the Professional plan.
MyProtektor does not track guards with a simple fixed interval. The app uses battery-adaptive location tracking that adjusts update frequency based on the device's current battery level and charging state.
| Battery state | GPS update interval |
|---|---|
| Charging | Every 60 seconds |
| Above 50% | Every 120 seconds |
| 20% to 50% | Every 180 seconds |
| 20% or below | Every 300 seconds (5 minutes) |
When a guard's phone is plugged in or fully charged, the system sends positions more often. As the battery drops, intervals widen automatically to preserve battery life. This means guards on long shifts see their update frequency slow gradually rather than their phone dying mid-shift.
The app also filters out poor-quality GPS readings, common when guards are inside buildings or near dense structures, to prevent false position data on the guard map.
| Tracking approach | Typical battery impact per 8h |
|---|---|
| Continuous GPS (every second) | 15–25% |
| MyProtektor battery-adaptive GPS | 5–8% |
| Manual check-in only | near zero, but no real-time visibility |
What the tracking system does NOT do
- No movement pattern detection. The system does not detect whether a guard is moving or stationary. Update frequency is based on battery level only.
- No speed tracking. The system does not measure or report guard speed.
- No geofence enforcement. There are no site boundaries or alerts when a guard leaves an area.
What affects the numbers
- Network type, WiFi uses less battery than mobile data (LTE/4G). Guards on site WiFi will see the lower end of the range.
- Signal strength, a phone searching for a weak mobile or GPS signal uses more power. Good coverage means lower consumption.
- Device brand, newer Samsung devices handled background location very efficiently in our tests (under 1% battery per 8 hours for tracking alone), while an older Huawei device used closer to 3%. The 5–8% range accounts for this variation plus normal app usage.
- Battery age, an older battery with reduced capacity shows a higher percentage drain. A two-year-old phone may show 8% where a new phone shows 5%.
Planning Data Allowances
If you are provisioning SIM cards or setting data budgets for your guard team, use these figures:
| Shift pattern | Per shift | 26 shifts per month |
|---|---|---|
| Mostly quiet shifts | 10–15 MB | 260–390 MB |
| Mix of quiet and busy shifts | 15–20 MB | 390–520 MB |
| Mostly busy shifts (frequent incidents with photos) | 20–30 MB | 520–780 MB |
For most guard teams, a 500 MB to 1 GB monthly data package covers MyProtektor comfortably and leaves capacity for other apps.
Device Recommendations
MyProtektor runs on modern Android and iPhone devices. For reliable background tracking, we recommend:
- Battery capacity: 4000 mAh or higher, standard in most smartphones manufactured from 2021 onwards
- Operating system: Android 10 or higher, or iPhone running a current iOS version
- Storage: the app requires less than 100 MB
A note on certain Android brands: Huawei, Xiaomi, Oppo, and some Samsung models apply aggressive battery optimisation that can interrupt background tracking. If your guards use devices from these brands, you will need to adjust the battery settings for MyProtektor, see the troubleshooting section below.
Briefing Your Guards
When guards receive the app, share these points during onboarding:
- The app does not drain your battery. It typically uses 5–8% over a full shift. Your phone will last the entire day. Higher usage usually means frequent photo uploads or weak signal, both are normal.
- Data usage is very small. A normal shift uses 10–30 MB, much less than browsing social media or watching a single video.
- Do not force-close the app. The persistent notification on Android is normal. It means location tracking and emergency alerts are active. If you dismiss the notification or force-stop the app, the control room loses your position.
- Check your battery settings. On some phones (especially Huawei and Xiaomi), go to Settings > Battery > App Launch and set MyProtektor to Manage manually with all toggles enabled. This prevents the phone from killing the app during your shift.
How We Measured These Figures
The baseline figures on this page were collected from real devices running MyProtektor during active duty:
| Parameter | Device 1 | Device 2 |
|---|---|---|
| Device | Huawei (4000 mAh) | Samsung (4000 mAh) |
| Duty duration | approximately 20 hours | approximately 17 hours |
| Network | WiFi | WiFi |
| GPS interval | 120 seconds | 120 seconds |
| Battery (tracking only) | approximately 2–3% per 8 hours | under 1% per 8 hours |
| Data (tracking only) | approximately 5 MB per 8 hours | approximately 4 MB per 8 hours |
The Samsung device handled background tasks more efficiently, while the Huawei device's battery management interrupted most background jobs, the app compensated through its foreground service. Both devices remained usable for duty tracking, but background task efficiency varied significantly by manufacturer.
Active app usage (incident reports with photos, QR scans, map browsing) adds to these baseline figures. The ranges at the top of this page account for both background tracking and typical shift activity.
Troubleshooting
A guard reports high battery drain during shifts.
- Check whether the guard ended their previous shift in the app. If a shift is still active, tracking continues even when the guard is off duty.
- Check the phone's per-app battery usage screen (Settings > Battery > App usage) to confirm whether MyProtektor is actually the cause or whether another app is responsible.
A guard's phone gets warm during shifts.
- This usually indicates the phone is struggling to acquire a GPS signal, common indoors, in basements, or near dense structures. The GPS radio stays active longer when searching for satellites.
- Check whether the phone case blocks the GPS antenna area (typically the top edge of the phone).
The app is killed by the phone during a shift.
- This is common on Huawei, Xiaomi, Oppo, and some Samsung devices with aggressive battery optimisation.
- Go to Settings > Battery > App Launch (or equivalent on the specific brand) and set MyProtektor to Manage manually with Auto-launch, Secondary launch, and Run in background all enabled.
- On Huawei devices specifically, also check Settings > Battery > Battery Optimisation and set MyProtektor to Don't optimise.
Data usage seems higher than expected.
- Check per-app data usage in Settings > Network > Data Usage to isolate whether MyProtektor or another app is consuming the data.
- The most common reason for higher data usage is incident reports with multiple photos. Each photo adds 0.5–2 MB depending on image quality. This is normal and expected.
