Using HPM eliminates confounding factors. You won't get real world numbers because some of the benefit is provided by the OS/hardware, but you'll know if your changes are actually making a difference during the times that they are active.
- hendersoon 10y agoIt's simply not an appropriate test. You don't use high performance mode when you care about battery life.
- throwanem 10y agoI don't get your objection here. Not only does high-performance mode eliminate OS-level confounders that would otherwise render consumption deltas highly questionable, it does so in a way that produces worst-case results. What exactly are you complaining about?
- hendersoon 10y agoAll that other stuff impacts battery life in a huge way. Those variables matter. You can't just remove them, call it a "worst case scenario", and walk away. That is not valid. When a reputable site like Anandtech reviews a laptop, they don't force it to maximum performance mode, because nobody that cares about battery life would ever do that. It's testing a scenario that _doesn't matter_. In fact, not only is it not the default, but maximum performance mode doesn't even _show_ by default-- you need to expand a "show additional plans" dropdown in the power control panel to see it. Opera went to the trouble to do that, and it was not by accident.
- SapphireSun 10y agoI think you're looking for a followup study that complements these results, but that study would be not as valuable as with these to inform their interpretation.
