Minor gripe: the amp hours of the battery don't tell you anything about actual battery life. I worked for a phone manufacturer for a while and saw devices with 3000mAh batteries that couldn't last a day of idling and I saw devices with 1400mAh batteries that would go a week if you just left it sitting in on the table and didn't touch it. It's all about the efficiency of the SoC before the battery amperage comes into play

Another interesting thing is that charging speeds will vary depending more on the protocol used than the wattage of the charger. A 15w Qualcomm Quick Charge charger will charge a nearly dead phone up to 100% in about an hour, or to 78% in 20-30 minutes, but an old 5v 3Amp charger will take a good 2 hours or more to charge the same phone

My current job has me provisioning iPads into our MDM to send out to the field and holy crap am I sick of plugging 6 iPads into a mess of chargers and waiting hours for them to get up to 50%ish, so i do agree 100% that apple needs to get with the times
