Anyone who has a smartphone knows that battery life is an issue. At the moment, the smartphone industry tends to favor performance over battery life when developing specifications for their new devices. To be perfectly honest, I am all for this. I would argue that it's better to have a zippy phone that acts quickly when I need it to rather than a slow, less sleek device that can withstand a few days of use without charging.

This is probably because I've mastered getting what I need from my phone while using the smallest amount of battery resources possible. Getting the best battery life from your phone can be somewhat complicated because everyone has a different opinion on what you should use and which (if any) features you should sacrifice to conserve battery. Fortunately, I have a simple method that works for every Android phone I've ever encountered.



Display Screen

As a universal fact across all phones, the biggest drain on your battery is your display screen. Personally, I've found the auto-brightness control to work extremely well. To adjust to auto-brightness, go to 
SettingsàDisplay settingsàBrightness, and then just check Automatic brightness. It dims the brightness when you're in darker rooms (as it doesn't need to compete against other light sources and glare), but will really up the brightness if you're outside so that your phone is actually usable. However, if I'm really trying to conserve battery, I will turn off auto-brightness and set the brightness to very low (around 25%).

Also be sure that you don't have an extremely long timeout (inactivity time before your screen automatically shuts off) as this will drain your battery. I personally just prefer shutting the screen off manually by pressing the power button rather than waiting for a timeout; this way my phone won't timeout on me when I am just reading something on it.

The Power Control Widget

If you have a fairly recent phone (anything running Android 2.1 or higher), you are blessed with a completely awesome "Power control" widget. This is a must for your home-screen. With this widget, you can enable and disable WiFi, Bluetooth, GPS, and Auto-sync in addition to adjusting brightness levels between auto, low, medium, and high.

The only thing this widget left me wanting was the ability to enable and disable mobile wireless (3G and/or 4G network). Some phones allow you to do this by pulling down the "status bar" at the top of your phone (where notifications, battery life, and signal are) and selecting or unselecting "Mobile data." Other phones allow you to control mobile wireless networks by holding down the power button. Worst case scenario, you can adjust it in "Settings." Although, an app called "Quick settings" can achieve this (and many other) functions much more quickly.

Now, when to enable and disable these features, all boils down to preference. I only use Bluetooth, WiFi, and GPS as I need it; otherwise it's off. If you have a WiFi connection available, it's generally better for your battery to use it rather than using your mobile wireless network (especially if you get poor signal for your mobile wireless).
