(Updated Comparison Post: ART vs. Dalvik): https://thelostdigit.com/2014/08/07/art-vs-dalvik-oneplus-one-battery-life-review/

I have done a video showing some of the battery life results I have been getting for the past 2 weeks that give a good estimation of how the device performs while using the ART runtime. I have been fairly please getting 6-7 hours of screen on time consistently even though I have the worst signal in my room. I want to compare it to Dalvik and have switched back now to test it thoroughly to be able to compare. Once the testing is complete I will write a comparison post comparing the performance between the two.
