App is from Qualcomm.
I've never used apps the limit functionality to save battery before, but if anyone would know how to do this right, it should be Qualcomm.
Snapdragon™ BatteryGuru extends battery performance and improves overall user experience by intelligently making changes that optimize Snapdragon device functionality. This app:
• Delivers longer battery life with fewer charges
• Intelligently learns how you use your Snapdragon smartphone and optimizes your device without disabling smartphone functionality
• Requires no user configuration - Snapdragon BatteryGuru automatically learns and adjusts the smartphone settings so you don’t have to.
After a brief 2-4 day introduction period, Snapdragon BatteryGuru learns the user’s behaviors and then notifies the user that it is ready to extend the battery life and improve the experience. Snapdragon BatteryGuru continues to operate in the background, deepening its understanding of the user and further optimizing the experience over time.
