## **Android Related Issues**

### **Battery optimization**

Android has implemented battery saving setting that are enabled by default. These settings automatically suspend/pause applications that are not required for the system to function to help conserve the amount of battery energy used by apps that don't always need to be running.

When this is enabled, it will very likely cause issue for **AAPS** and other supporting apps like **xDrip+**.

It's important to ensure that you have disabled Battery Optimization to ensure **AAPS** and other supporting apps remain active all the time.

Depending on your phone model and make there may be more than one location and setting which needs to have this disabled.

***NOTE:** Follow the steps below to Disable Battery Optimization for the Bluetooth service if your phone has this option, the same steps can be used to disable for **AAPS** and other apps, however the screenshots will only show how to do this for the Bluetooth service.*

#### **Pixel phones (stock Android)**

* Go to the Android settings, select "Apps".
