I think it largely depends on what you get in return. If I get to charge the device once every two days instead of once a day, sure, but if I get to attach my device at night with 10% of battery left instead of 3%, no: the increased battery on regular basis it doesn't give me any value (I still have to charge it every night), but on the other hand, the increased size does give me a drawback on regular basis (the phone is larger and heavier). I, personally, would have loved to have a larger battery and no camera bulge, BUT, when I tried a cover that would even out the back of the phone (just like a larger battery might have done), I found the phone noticeably larger and, finally, went back to the non-covered phone. I'm pretty sure at Apple people have carefully decided how large a battery had to be to reach 1 day (say 18 hours) of regular usage and they designed the device size around it.
