> Start by not requiring a screwdriver in the process of changing batteries. I remember the early days of Samsung/Android phones where you only needed to pry open the back cover using your nail and the battery was easily taken out God no. With those designs you lose so much capacity to the extra stuff required to support it. You effectively need two backs—one to cover the battery and another to cover the components inside. You also largely lose the ability to do non-rectangular/multi-cell batteries, which is critical to maximising capacity in many modern phones.
