Or they could've been more transparent, everyone knows batteries dont last as long after 1-2 years, but they decided to gimp them down (and effectively slowing them down, even if you dont like that term, it is what it is). Their batteries are sub-par in capacity compared to most manufacturers (They hadnt even passed 2000 mAh until the 6 plus/6s plus, and their non-plus models have never passed 2000 mAh, only the X's have more than 2000)
