Ever since I published a blog post on my Samsung Galaxy’s battery life, I’ve been getting a lot of requests on how to extend the battery life of various Android devices, as the previous post was more of an overview as opposed to a detailed step-by-step tutorial. Before I give you the exact steps, I would like to do a little disclaimer: The battery life of your device will ultimately depend on the device that you own. I’m no expert in hardware and I definitely haven’t done a lot of research on what kind of batteries all the different Android Devices use. So I’ll be approaching this topic from a more generic angle; more specifically, I’ll be focusing on the Android OS, as opposed to individual devices. Maybe in the future I might consider doing a little User Guide to the battery life’s of all the major Android and iOS devices – but that’s in the future. For now, let’s just focus on the Android OS.
