We all know our beloved Android phones are not battery friendly, and we try our best to conserve the battery to at least get us through the dreaded work day. Extended batteries, toggles, and battery saver apps can also help with the life of your battery. Even though Ice Cream Sandwich has impressive battery life with all the features it has, there is still a simple method you can use to make it even better.
For those of you that were lucky to get a Samsung Galaxy Nexus, here is a simple little thing you can do to help increase your battery’s life. TURNING OFF YOUR 4G. Easy right? Lets face facts. It is going to take a while for the 4G LTE to get into every nook and cranny of the Earth’s plain, and if you live in a city that does not have 4G or sometimes gets 4G, your phone is wasting power scanning for that 4G signal. So lets turn that scanning off. It is as simple as, Settings>More…>Mobile Networks>and turning it from LTE/CDMA to just CDMA. You will now remain with constant 3G and your phone will save that power it was using trying to find 4G.
Why would you want to turn off that awesome 4G though? I am not saying just remain on 3G the whole day, just for those times where you are not really using your phone. You can also look in the market to see if there is a special toggle for this method, so instead of going through your settings you can place the toggle on your home screen and tap it once for it to bring you right to the preferred network window. This will make it easier for you to go back and forth between 3G and 4G.
A lot of you probably already knew this little trick. I use this method with my phone on T-Mobile‘s network, where I turn the HSPA+ off when I am not really using my phone for downloading or browsing through apps. It helps the battery  a ton. This method especially will help your Galaxy Nexus out since Big Red is having constant problems these days, keeping their 4G LTE from cutting out. Silly Verizon and their awesome broadband service that is to powerful for even them to handle. Give it a shot and see if it helps you out.
