I improved my battery life by restoring my DD, Stock 4.1.2 Nandroid. I can't see getting this much standby/screen combined time on our official KK, yet. Plus, I had issues with lagging and bugs (such as constant playback errors with Google Play All access). The only thing I miss is the greatly improved Stereo Bluetooth quality in 4.4 vs v the too-bad-to-listen on 4.1. If anyone could tell me if/how to edit those libs/files I'd not even care if I ever get stable KK on the e980. Anyway, organic battery usage.
I'm gonna let it run till dead and predict 72+hours with 4+ screen.
