The Battery Log application
Developer: Hwang Tae-rok | Download: Android |

We said this is simple, but it takes some time, so the next thing you need to do is just keep using your smartphone like you normally do, with one exception. Try to use your device from fully charged to fully drained, without intermittent charging. You can do this once, or for more reliable data - use your phone like this for around a week (set a reminder to check the battery log after that). In the meantime, the battery logger will run in the background and gather valuable data.

You now have your precious real battery life use numbers! Just calculate the hours that your phone lasted from ‘Unplugged’ to ‘Plug (AC)’ or ‘0%’, and you have your battery life. In our case, we used the Samsung Galaxy Note 3 for exactly 28 hours and 59 seconds, or 1 full day and 4 hours on January 28th, and for 1 day 10 hours and 8 seconds on January 27th. That brings our average use to around 31 hours, or 1 day and 7 hours, so we - with our unique usage - can expect somewhere between a day and a day and a half of real use before we get to the charger.
And what about you, how long does your phone really last?
