Battery Guru is the app you need to check if your device has Doze power-saving mode.

Doze mode is a built-in battery-saving feature on Android devices that can significantly reduce battery consumption by deferring background CPU and network activity for apps when the device is unused for long periods of time.

Battery Guru is a simple app that checks if your device has Doze mode. With just a few taps, you can easily understand Doze mode and determine if it's enabled on your device.

The "Battery Information" feature is a useful tool available in Battery Guru that allows you to check the status of your device's battery. When you open the feature, it provides you with detailed information about your battery, including:
Battery Level: Shows the current battery level as a percentage.
Status: Indicates whether the battery is currently charging, discharging, full, not charging, or if the status is unknown.
Plugged: Informs you if your device is connected to a power source, and if so, whether it's plugged into AC power, USB, wirelessly, or if it's not plugged in at all.
Health: Gives an overview of the battery's health, such as whether it's in good condition, overheating, dead, experiencing over voltage, an unspecified failure, cold, or if the health status is unknown.
Temperature: Displays the current temperature of the battery in degrees Celsius.
Voltage: Shows the battery voltage in millivolts.
Battery Present: Indicates whether a battery is present in your device.
Battery Technology: Informs you about the type of battery technology used in your device, such as Lithium-ion (Li-ion) or Nickel Metal Hydride (NiMH).

By providing you with this information, the app helps you keep track of your battery's status and health, allowing you to make informed decisions about your device's power usage.
