    I'm using KitKat and ART and battery has increased by 20-30 mins on screen and an hour or so extra standby. Before it would be dead at 7PM now it goes till 8-9PM

    I could tell you my battery life if I manage to go 24hours without flashing my Nexus, but I don't use it as a calling phone.

    I find the battery life to be better overall as long as everything works properly, seem to be getting wakelocks lately alot. Standby drain is less and battery drain during a call seems less as well, on jellybean my battery tanked on a phone call! I am using ART aswell.

    Battery life is better after the 4.4 update. I started using ART, but I haven't seen better battery life because of it.

    Strange. I have seen massive improvements.

    I was already getting really good battery life as it was. I really watch what apps I have running in the background as well as all the other tricks. ART definitely opens apps alot quicker amd makes my whole system snappier. I haven't run into any problems since using ART.... all my apps work fine. I would recommend using it.

    Can't use numbers as I haven't tested it but it seams to be slightly more efficient.

    I used ART as well and didn't notice any battery improvements.

    Battery life has improved since 4.4 upgrade though.

    Don't see any improvement.
    More than that, sometimes Google Services (two or tree of them) start in background and drain battery slowly. Didn't see it at 4.3.

    That used to happen in 4.3 also and certainly isn't any better in 4.4. I wish Google would fix this serious issue.
