In the words of Google co-founder Larry Page, "if you are not getting a day [of Android battery] there is something wrong." There must be "something wrong" with a lot of our phones, so hence the How-To Geek's practical guide.
The website has created a comprehensive tutorial on how to hack, fiddle and twiddle with the settings of an Android phone, to get the best out of the meager battery life. It's long, but accompanied with large photos explaining every step of the way.
Some of the steps involve downloading apps, but most are to do with disabling life-sucking apps and functions. It might make your usage slightly leaner, but at least you'll be able to get to work and back each day without having to take a charger with you. [The How-To-Geek via LifeHacker]
