I am really curious to see if there will be noticeable "real world" battery life improvements. On paper they have done things which SHOULD give us improvements (ART, and "Project Volta" scheduling), however it remains to be seen just how well those theoreticals will translate into improvements on the ground. I have read reports from people who have tried the developer preview, however their anecdotes vary so wildly (e.g. 10-60% improvements) it is hard to believe any of them. Need something more scientific than people's vague "I got more hours today than yesterday."

Ars Technica reported pretty significant improvements http://arstechnica.com/gadgets/2014/07/examining-project-volta-we-put-android-l-through-our-battery-test/ http://arstechnica.com/gadgets/2014/07/examining-project-vol...

Speaking just as a developer updating code for L-devices, the new scheduling interface almost guarantees an improvement depending on how many apps that sync in the background you have installed. The paradigm went from "wake up every 10 minutes, turn on the CPU, check for network, try to do stuff, if you fail, try again in 10 minutes, keep waking up the device" to "tell the device to do my stuff when next there is network and sufficient battery and the CPU is already on for the sake of running other tasks".

It is very hard to measure battery life. Testing it on a buggy developer preview is entirely irrelevant. Volta and ART will improve battery life but they can't do anything for a shitty app that requests your location every second ..
