Smartphones are no longer just call devices, becoming indispensable life companions where geo-positioning plays a key role. Owners of the popular Xiaomi Redmi Note 4 model often face the need to activate GPS to operate a taxi, deliver food or navigate in an unfamiliar city. Without a properly functioning module, many applications lose their functionality, turning into a useless set of icons on the screen.
The activation process may seem elementary, but there are hidden nuances in the MIUI shell that affect the accuracy and speed of positioning. Incorrect power saving settings or lack of permissions can negate all user efforts, causing the map to “jump” or show location with a huge error. In this article, we will discuss in detail all the steps of the satellite module’s operation and optimization.
It’s worth noting that the hardware of the Redmi Note 4 is equipped with a reliable receiver that can work even in dense urban areas. However, software conflicts or system settings failure sometimes block applications from accessing location data. Understanding how these mechanisms work will allow you to avoid common errors and ensure that navigation services work smoothly in any situation.
Basic activation through the notification panel
The fastest way to start looking for satellites is to use a quick-tuning curtain, which is ideal for situations where geolocation is urgent and short-term, and just swipe down from top to bottom to open the control panel and find the appropriate icon.
The icon usually looks like an inverted arrow or compass, and if you can't see it on the first screen, try swiping right to open additional pages of widgets, and pressing activates the module, and the system will start scanning the ether to get signals from satellite constellations.
⚠️ Note: When activated through a curtain, the system may request permission confirmation. If you see a pop-up asking about allowing Google Play Services to use geodata, be sure to agree, otherwise the positioning accuracy will drop sharply.
It is important to understand that this way of turning on often only activates the basic mode of operation, which may not use all available data sources, such as Wi-Fi or mobile networks. For full navigation in the car or when walking, this may not be enough, and you will need a deeper setup through the menu parameters.
Once turned on, the icon in the curtain should light up, usually blue or green, which signals the start of the module. However, the visual presence of the icon does not guarantee that the phone already “sees” satellites – the initial capture process can take from a few seconds to a couple of minutes, especially if the device was long off.
Configure through the system menu of parameters
To gain full control of the navigation module, you need to go to the deep settings menu, where the user can select high-precision modes, which are critical to correctly display your position on the map. Go to Settings → Advanced Settings → Privacy.
In the privacy section, look for location, and that's where the main controls are, and the slider at the top of the screen starts the whole set of coordinate services, but the real magic is just below the definition method.
The system will offer several options, among which you need to choose the most suitable for your tasks.
- 🛰️ Satellite GPS — It uses only spacecraft signals, works slowly, but independently of the Internet.
- 📶 According to the coordinates of the network - determines the position on the towers of cellular communication and Wi-Fi, works quickly, but with a large error.
- 🚀 High accuracy – combines all available data sources for the fastest and most accurate result.
For owners of Xiaomi Redmi Note 4, it is recommended to always choose a high-precision mode, since the device's processor copes with data processing without significantly affecting autonomy. Using only GPS in urban environments often leads to errors due to the "urban canyon" effect, when the signal is reflected from buildings.
💡
Turn on Wi-Fi scanning even when the Wi-Fi module is off, allowing the phone to use access point databases to instantly determine location, which is especially useful inside buildings where satellite signal is weak.
Remember that after changing the settings, the system takes some time to restructure the search algorithms. If you switch from energy saving mode to high accuracy, give the device 2-3 minutes to stabilize the connection before starting the navigator.
Managing permissions for applications
Even with GPS enabled, a particular application may not be able to access that data. In MIUI, security controls tightly on access to personal information. If a navigator or taxi shows an error, it's likely that the problem lies in the access rights.
Go to Settings → Apps → All apps. Find a program you want, like Yandex Maps or Uber, and look for permissions inside the app menu and make sure you access your location in Always or When Used Only mode.
And you have to pay special attention to background resolutions, because many activity trackers or delivery services have to work even when the screen is off, and if you limit their background activity, you can't track the courier in real time.
Consider the main types of access and their impact on the operation of programs:
| Type of access | Description | Impact on the battery |
|---|---|---|
| Forbidden. | App doesn't see coordinates | Absent. |
| Only when used | It works when the application is open. | Average. |
| Always. | Continuous monitoring in the background | High. |
| Once. | Temporary access prior to restart | Low. |
Some versions of MIUI firmware have a bug where permissions are reset after updating, so if a previously running application suddenly stops determining location, check that settings section first, rather than rushing to reinstall the program.

Battery optimization and GPS operation
Xiaomi’s aggressive energy-saving system is often the main enemy of stable navigation. To extend battery life, the system can force the GPS-based processes to stop, even if you need them at the moment.
You need to add navigation apps to the exception list. To do this, go to Settings → Battery → Settings. Here you can turn off the energy savings for selected programs or put them in "No Limits" mode, which allows the GPS module to work continuously.
There's also a hidden mechanism for freezing background processes, so if you're actively using your navigator on your trip, make sure it's stored in your memory, open the menu of running apps, click on the lock icon next to the window, and it prevents it from being uploaded by the system.
⚠️ Warning: Flight mode completely disables all wireless modules, including GPS-Do not use this mode, if you need navigation without a SIM card, it is better to simply turn off mobile data transmission, leaving the navigation. GPS vigorous.
There is a myth that GPS is fast-burning, and on modern devices like the Redmi Note 4, the energy consumption of navigation is comparable to watching videos or playing games, and much more energy is spent constantly searching for the network when the signal is bad than on the correct operation of the satellite module.
How does GPS affect battery wear?
Calibration and signal accuracy
Sometimes it happens that geolocation is turned on, but the arrow on the map is randomly tossed or shows the wrong direction, which indicates the need to calibrate the sensors. Android has built-in tools to solve this problem.
The most effective way is to use a special engineering menu or third-party utilities, but to start with, try a simple method: open Google maps, click on the blue dot of your location and select Calibrate. The phone will ask you to move your hand through space, describing the eight.
If the software calibration doesn't work, you can use the Redmi Note 4 engineering menu. In the Phone app, dial ##6484##. In the menu that opens, select Single Item Test and find the GPS test. Here you can see the number of satellites visible and the signal level.
Critical factors affecting accuracy:
- 🌤️ Open Skies – Being indoors or under a metal roof significantly reduces accuracy.
- 🧲 Magnetic fields – magnetic fastener covers can work as a compass, knocking down orientation.
- 📡 Antennas in the Redmi Note 4 model antennas GPS are located in the upper part of the body, do not close this area with your hand when navigating.
In case of serious problems with receiving the signal, you may need to reset the A-GPS data. This will not delete your personal data, but will clear the cache of the satellites' almanac, forcing the phone to re-download current data about their orbits. This often helps if the phone has been lying unused for a long time.
💡
Regular compass calibration and A-GPS cache reset solve 90% of the problems with the “jumping” arrow on the map.
