John says his smartphone's lithium ion battery doesn't have very good battery life at all. Leo says that is an odd development. Batteries are limited to about 500 charging cycles. You keep about 80% of your capacity throughout the life of the battery. Go with manufacturer brands. Anker, though, is a good third party brand.

John wants to know how to properly take care of his batteries. There's a huge variety of advice about Lithium-ion batteries, but Leo says there's just a few things to keep in mind for extending the life of a battery. First, keep it charged. A Lithium-ion battery has about 500 recharge cycles in it. By keeping it charged and plugged in more often, it won't discharge and use up a cycle. He doesn't have to worry about overcharging either, because there's circuitry that prevents it from charging once it's fully charged. Secondly, if he's storing it long-term, he should keep it at 50% capacity.
