Battery Temperature and how it affects the Battery Life

Temperature effects on Lithium-based batteries

smartphone battery explodes
The worst case:
An overheated and exploded lithium-based battery
While working on my latest app "Battery Temperature Guard" I learned a lot of new stuff about smartphones, batteries and of course Lithium-Based Batteries. These are the kinds of batteries used in most modern smartphones, notebooks and mp3-players.
A lithium-based Battery is quite a cool thing, cause it can recharge very fast and doesn't have the common memory effect known from old batteries.
This article is quite interesting to learn more about lithium-based batteries and how you can increase your battery life.

To keep your battery healthy follow their instructions:


A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.
Elevated temperature hastens capacity loss. The capacity cannot be restored. Not all Li-ion systems behave the same. 

Battery temperature and battery health

As you can clearly see in this listing, the battery capacity is constantly influenced by the battery temperature. If your battery is always above a level of 40°C your battery will loss its capacity quickly and will have limited capacity after a few month. In this example it is 65% less! That is more then a half!

How to keep the battery healthy
