Saving battery: Marshmallow's Doze mode for all Androids.

Features & Capabilities

Dozzzer is a powerful Chrome extension that brings the official Marshmallow Doze mode's battery-saving benefits to all Android devices, including older versions like Gingerbread. By intelligently controlling internet connectivity—which is one of the biggest battery drains—Dozzzer saves significant battery life when your device is idle.

This extension is highly configurable with modes such as Eager (activates immediately after the screen turns off), Medium (after 5 minutes idle with minor message delays), and Lazy (after 10 minutes idle) allowing users to balance between battery conservation and timely message reception. It uses a local VPN firewall approach to manage data access on Lollipop and newer devices without posing any security risks. Moreover, it can exclude specific apps from its restrictions for uninterrupted communication. Dozzzer even enhances battery savings on Marshmallow with its customizable settings, making it a must-have battery optimization tool for all Android users.

User Reviews

Dozzzer is praised for effectively saving significant battery life, primarily by managing background activity and working seamlessly when the screen is off. Users appreciate its simplicity and performance over built-in savers. However, the app suffers from a lack of updates and maintenance, causing compatibility problems with new Android versions and unstable VPN connectivity that affects network performance. Some users find mode descriptions unclear, and experiences vary across devices. Overall, it's a useful app but could benefit from updates and improved stability.

VPN connection used by the app is unstable, frequently turning off and causing lag or connectivity problems.

Hello, my honor 70 lite has just received an update a couple of days ago from android 12 to android 14. I did a factory reset on it and now the app is no longer compatible with my phone. Please could you update the app for the benefit of others as well as myself, perhaps throw in a dark theme? Thankyou.
