Samsung Battery Runtimes

Introduction

This page documents runtime tests performed by Samsung users. The intention is to compare battery runtimes across a range of conditions and SVN revisions.

For test methodology see BatteryRuntime

Charging Analysis: As you can see, the hardware stops charging at around 8700, which makes around 2:30h needed for charging. It restarts charging at ~4140mV and reaches the maximum after 5:00h. Unfortunately, battery bench apparently didn't catch the actual peek voltage. Therefore, a charging cycle seems to take 2,5h and should be hit accurately for a maximum runtime.

Discharging Analysis: The curve isn't quite linear, and there's a big drop at the end. At least, I was able to figure out the peek voltage here. The hardware turned off itself at the very end.
