sure, but we're at a point with battery chemistry where that no longer really matters that much. the fairphone 4 is already at 3900 mAh and with both phone electronics constantly getting smaller and battery chemistry improving, it's highly likely that this year's fairphone 5 will not only crack the 4000 mAh barrier but fly past it. with a modern mid-range soc (which is really all you need to have a smooth experience outside of games) it' more than enough to get you through the day with a good margin to spare. and that's already a user-servicable design that no doubt guided eu legislature on this issue.
