I recently purchased a new Android-based mobile phone. I spent the first day checking out all the features and options, downloading a bunch of applications, and experimenting with the GPS and location-based services. It didn’t take very long to notice the battery drained relatively quickly.
The problem with the current generation of phones is that all the neat features also eat away at the battery. They have large bright screens. They have connections for 3G, Wi-Fi, and GPS. They connect to the Internet. They have applications that run in the background to provide alerts.
Simply put, cellphones spend a lot of time connected to their chargers these days.
Here are a few things one can do to extend cellphone battery life:
Check the settings of your background applications and notifications: Having email, Twitter messages, Facebook updates, and calendar appointments delivered minute-by-minute is perhaps the largest battery drain. Resetting the email polling interval from every 5 minutes to an hour will do wonders for battery life. If you keep multiple applications “open” for quicker access or alerts, run them only as needed. There is no need to get storm alerts if it is going to be 80 and sunny.
Turn off roaming/3G/4G when not needed: If you have good coverage and are mostly usind the phone for talking, or get only occasional email updates, there isn’t a need to keep such a wide wireless connection open.
Use location-based services onlt when needed: Having the phone constantly look for new Bluetooth devices, Wi-Fi hotspots, GPS positions definitely eats up battery. Find out how to turn these things off on your phone, or automate their use. Add shortcuts and widgets to the homescreen to make it easier to control the radios.
Play with screen time-outs, brightness, and backlight: Adjust the setting for how long the screen stays lit after a quick check of the clock. Turn on automatic brightness so the screen auto-adjusts in light and dark environments rather than having brightness turned all the way up. Alternatively, lower the default screen brightness.
Keep it cool: Avoid keeping the battery at full charge and high temperature. This is the case when placing a cell phone or spare battery in a hot car. Keep it out of your pocket and away from your body heat whenever possible.
Turn off live wallpapers and vibrate; lower ringer volume: They do use processing power and eat into the battery life.
