Well yeah, but it isn't the battery capacity that is of interest to users. What users want to know is how long it lasts. So a smaller battery on a Snapdragon 800 will last longer than the same battery on a older (larger process) chipset. Likewise, a phone with a smaller screen can be reasonably expected to be more frugal.
So, prospective buyers usually have to take qualitative assessments, such as "a couple of days of medium to heavy use"*.That sounds about right for this Z1 Compact, given reviews of other phones with a Snapdragon 800 chip, such as the LG G2 and Nexus 5.
All the mAh figure does for the layman is allow some comparison to batteries in other phones. It's my assumption that most phones batteries have 3.7 V units, so a mAh figure is just fine with me.
