After Apple's recent fiasco, it's now common knowledge that smartphone batteries degrade over time. But aside from causing terrible battery life, a degraded battery can also trick your phone's software into thinking the device has more juice left than it actually does.
For most automotive applications a battery needs to supply a lot of current for a short period of time to turn over the engine and get the car started. With the engine running, the car's alternator produces all the power the car needs. Thin plates inside a starting battery increase the surface area and produce this relative burst of energy. Thicker plates in a deep cycle battery provide a steady amount of current over a long period of time. Deep cycle batteries excel in reserve capacity (RC),...

It's no secret that Google is all about AI. In their eyes, machine learning is the future of software development, and you can see evidence of this all over the last couple Android updates. They've used it to power all sorts of features in their Pixel phones, and they've even donated some of their AI smarts to AOSP for all Android manufacturers to share. But it looks like Samsung isn't exactly on board.

Fortunately, instead of restoring your jailbreak and tweaks manually after recovering from a critically low battery, you can avoid it altogether.
