Once upon a time, math teachers everywhere relied on the phrase “You won’t always have a calculator in your pocket!” to justify why you needed to cram the Pythagorean theorem over the weekend. They were wrong. So wrong, in fact, that we all don’t just have calculators in our pockets at all times but high powered, hand held super computers capable of gaming, streaming music, watching videos, and so much more. The downside is that smartphones require a lot of battery juice to keep them going. With so much of our lives taking place online and in the palms of our hands these days it's next to impossible to just sit your phone down somewhere and wait for it to take 8-10 hours to charge.
There’s been a lot of great advancements in charging technology including bumping up chargers to output 15W of power in an effort to speed things along, but even at that output many official MagSafe chargers can still require 8 hours to fully charge. The problem, then, is the generated heat from the act of charging your device. As the temperature of your device rises the ability for it to charge wirelessly becomes throttled. Continuing to use the phone while it is charging, especially for CPU-intensive apps like watching videos, can make matters even worse.
