Now, thanks to an excellent app for measuring battery use called Battery Stats Plus by
Root Installer, we were able to find battery usage stats for numerous battery-related apps that users had uploaded to their website. We were also especially happy to find that an app we recommended before, BitDefender Antivirus Free, had battery usage of only 0.06%.
We then found the most popular battery-related apps, both paid and free, in the Google Play Top 500 apps for the Tools, Productivity or Widgets categories. We wrote down the battery usage for each app from the Battery Stats Plus website. After seeing the list of battery savers when we finished, we decided to add one free app which wasn't in the Top 500 in any category, but which we felt deserved to be included, BatteryFu battery saver.
We felt compelled to share this list, in particular so our Battery Notifier Pro BT users with the less than 0.01% battery use can brag to all their friends who have some other battery app installed on their phones. BTW, both versions of Battery Stats Plus by Root Installer are also very good, and if you feel so inclined, we encourage users of both our apps to download that app, and then upload stats to the Battery Stats Plus website.
Here then is the list of 57 battery-related apps, 56 found both in the top 500 paid and free apps on Google Play, in the Tools, Productivity or Widgets categories, and at the Battery Stats Plus website. In addition to the battery usage percentage, we also list the number of permissions for each app, whether or not they have a permission to access the Internet, and whether or not they display ads. Finally, we list if the apps have any privacy concerns.
