I'm not sure about ever been able to reach even close to 10 hours of battery life? However, you're right about the low playback-only consumption of the ES8316 codec (datasheet), but the additional consumption of two speaker amplifiers (XA9108) should be accounted as well. Unfortunately, I've been unable to find the datasheet for the XA9108 amplifier.
Until a better solution is available, increasing the total power draw of the laptop by about 7 to 15 mW is IMHO a very good trade-off for not having those annoying crackling/popping noises.
It goes 0,28,56,100, and in tandem with the Headphone Mixer and DAC controls seems to have the biggest effect on volume.
