Do you care if your phone has a replaceable battery?
Out of the major smartphone manufacturers, only Samsung and LG seem to have remained loyal to the removable battery concept this flagship season. The HTC One (M8) and Sony Xperia Z2 both sport premium designs, crafted out of metal or glass, but offer unibody sealed chassis that precludes you from swapping the battery.
LG G3, on the other hand, as well as the Samsung Galaxy S5, stick with fancy plastic solutions, but you can easily replace their units at will, and the S5 managed to be water-resistant, too, despite the removable back cover. LG's G2 flagship from last year had a sealed juicer, at least in its international reincarnation, but with the G3 the company is back to providing a more flexible design, while Samsung has never betrayed this concept, ever since the Galaxy S line inception. The Xperia Z2, however, sports a stellar battery endurance, almost as good as the Galaxy S5, while the One (M8) also provides battery life that is much above the average in our battery test.
Having access to the battery compartment of your phone means that you can carry a spare or two with you when you know you will be away from a charger for a while. Also, it might be helpful if your phone freezes to the extent that only taking out the battery might help, though these cases are rare. Last but not least, a removable back cover and replaceable battery usually means that third party companies can issue extended battery solutions which add less bulk than a charging case, or they might offer rear covers made of a more premium material.
That's why we wanted to ask you if you care about a replaceable battery in your smartphone that you can swap on the go, or if you are fine with a sealed battery compartment, as long as the battery life of the handset is in the acceptable range, like in the current crop of flagships.
