In the last time we (and many other apps) have seen issues with battery optimization techniques that some device manufacturers add to their devices. These battery optimization techniques try to save battery by limiting the execution of apps that run in the background. This can include: disable GPS, disable mobile network, stop the app, kill the app, or limit the functionality in different ways.

If the Kurviger app (or any other app) does not work properly after you minimize, lock the screen, or the display turns off, then this is usually because your smartphone tries to save battery. Different manufacturers use different and often custom techniques that are different to the default Android battery management. Some manufacturers are known to exclude some popular apps from their optimization, so some apps might work and other might now, which can be confusing.

Below is a list of manufacturers that use battery optimization techniques and how to disable them. If you know of any additional setting or other manufacturer that we should include, please let us know.

Huawei devices are known to use a very aggressive battery optimization. Different settings help different users, so we cannot guarantee that any of the settings below will help you, but they could.

You can try the following settings:

• Settings, Battery : manage Kurviger Pro manually. You need to set the switches to off.
• Settings, App Permissions, Special Access, Ignore Battery-Optimizations : Show all apps and set Kurviger to allowed.
• Settings, Advanced Settings, Batterymanager, Protected Apps: set Kurviger to protected.
• Go to the list of recent apps and click the lock next to the Kurviger app.

VLC disallows installing the VLC app through the Play Store for some Huawei devices because of their aggressive battery management.

Power saving mode needs to be turned off (Standard and Extreme).

Go to Settings, Power, Battery Optimization, All apps, select the Kurviger App and choose Don't optimize.

Samsung uses different menus in different Android versions, so the settings might be placed a bit differently on your device. Try the following:

• Apps, Settings, Battery, tap on more or the three dots, Optimize Battery Usage, All apps, and switch off the optimization for Kurviger Pro
• Settings, Device maintenance, Battery, Battery usage, Optimize battery usage, All apps, and switch off the optimization for Kurviger Pro.

Sony names it's battery optimization mode STAMINA mode. Please turn it off if you see issues with your Sony device.

For more details see the Sony support website.

Xiamoi's modified Android, called MIUI uses custom battery optimizations technology. The Android One devices don't and work as expected.

Go to Settings, Battery and performance, Manage apps battery usage → Off.

If you struggle with running the Kurviger app in the background, there are some app that might help you. We are not associated with any of these apps, so we cannot guarantee that they work.

We have seen GPS Status to help issues with GPS fixes and to keep the GPS activated, even in the background. This might even help if you see small GPS jumps.

If you see issues with your GPS being lost when you turn off the screen GPS Locker might help to fix this.
