These "advantages" to sealing the battery are incredibly weak/false. The weight difference from sealing the battery is negligible. If it saved several hundred of grams, it would one thing, but a replaceable battery adds at most tens of grams. Even if the sticker price of device is cheaper, I would still have to pay more to replace the entire device once the battery is worn. This is the primary reason for most companies sealing the battery, to force buying an entire phone. Having a replaceable battery would save me money. Sealing the battery was not responsible for waterproof phones. There were already waterproof phones with replaceable batteries.
