2 Battery - Battery Saver

Does your phone's battery drain faster than you'd like? Battery Saver extends your device's runtime by intelligently managing your Internet connection in the background—so you get hours of extra battery life without sacrificing connectivity or important notifications.

With over 10 million downloads, 2 Battery - Battery Saver uses a smart algorithm to automatically toggle your 3G, 4G, and WiFi connections based on your usage patterns. The result: less power consumption, reduced data usage, and longer standby time. You don't need to manually switch connections anymore—just install and forget, or fine-tune settings for maximum efficiency.

The app delivers real insights into your battery performance. Track detailed battery usage curves, see your current charge level in the status bar, and get accurate estimates of how long your device will last. You'll also receive notifications when your phone is fully charged and alerts when battery runs low. Advanced features include a built-in screen filter to reduce brightness impact, automatic screen-off when your phone is pocketed or placed face-down, and configurable whitelist and blacklist controls so critical apps always stay connected.

Customization is at your fingertips. Choose from multiple battery icon themes, enable night mode to reduce eye strain, and access home screen widgets for quick battery status checks. If you prefer a distraction-free experience, the PRO version removes all ads while unlocking premium features. SmartWatch compatibility means you get low battery warnings on your wearable too.

Try the PRO version risk-free for 24 hours—if it doesn't meet your needs, you'll get your money back. 2 Battery - Battery Saver has earned recognition as an AppNext 2013 best app and was selected as a Google I/O 2011 Developer Sandbox partner for its innovative approach to battery optimization. Compatible with Android 2.x through 8.x, it's built for devices that demand smarter power management.
