Why does my Android app occasionally drain the battery very quickly?
Several users of my app have reported that when my app is running in the background, their battery drains about 1% per minute. I can’t reproduce the issue even if the same account credentials are used on the same device model where the user has the error. Reinstalling the app apparently didn’t fix the problem, and it doesn’t seem that any specific Android version or device is associated with the issue. All the reports I receive are Samsung devices running 4.x, but this is also quite representative of my overall user base. My background service listens for GCM messages and contact list changes and triggers http requests approximately once an hour using ScheduledExecutorService.
I
should also note that I am not using any wakelocks in the app.
I was wondering if anyone knows what kind of error might be causing such a problem, or even what tools or methods might be effective in narrowing down my problem.
Solution
What percentage of users reported this problem? If you have tried it on a Samsung device running 4.x and have not experienced problems, it must be something other than your code.
