While that seems obvious, I’ll disagree

• phones have a charging curve that takes into account heat, battery level and probably more factors specific to battery health. Most of the additional charging speed is likely minimal effect
• You can have a battery replaced on even the latest iPhone for $99 or less, and I expect most phones to be cheaper. Yeah it’s not really diy nor replacement cost only, but it’s just not that bad relative to the cost of the device. Sure I’d rather spend $20 and replace my own battery, but if I’m spending $1,000 on a new phone, then $99 every 3-4 years for batteries is just not that bad
