Battery life has been and still is the biggest source of headache among mobile device users and one of the most important concerns of manufacturers. But while we wait for that almost perfect battery, the best we can do is to wisely manage our resource usage in order to curb battery drain. Qualcomm's Snapdragon BatteryGuru app, now at version 2.0, seeks to help users do just that by not making them think about it at all.
Qualcomm launched the Snapdragon BatteryGuru last May as an intelligent app that helps users reduce battery usage by automatically tweaking the system and its settings depending on the time of day or location. The app learns from the user's usage pattern and habits for a few days before it begins doing things on its own, without any prompting from the user. It can, for example, automatically turn off WiFi when the user leaves the house or learn that the user doesn't use certain features during certain hours and turns them off. Even after the initial training period, BatteryGuru continues to learn from the user and adjusts its settings appropriately.
Snapdragon BatteryGuru 2.0 still does all of those things. The improvement in this new version comes from the various notifications and feedback offered to the user. For example, the battery percentage is now periodically displayed on the notification bar. The notification area now also shows the the remaining battery life in hours and minutes. Users will also be reminded to charge the device if it determines that there is not enough juice left until the next regular charge time, which, of course, it has learned based on the user's habits. These latter two features are only available after BatteryGuru's 7-day learning period. Here's a short video that Qualcomm released during launch that shows the intelligent features of the app.
The latest Snapdragon BatteryGuru version is now available for free on Google Play Store but is only compatible with devices running Qualcomm Snapdragon chips. Fortunately, manufacturers and other third-party developers also offer their own battery management apps and tools as an option for those devices running on other processors.
