Given how much use it gets on a daily basis, the power button is always one of the first hardware features to call it quits on an Android phone or tablet. So if your power button is acting up, or you don't want it to, you can extend its lifetime by simply finding ways to use it less.
One of the biggest and least important uses of the power button is using it lock the device. Why least important? Because there are plenty of ways to turn your screen off and lock the device, and here are 9 great examples.
One of the simplest methods, which is still very convenient, is adding a softkey to your home screen. It'll be readily available, and with one tap, you'll be locking your device in a second or less.
With the application Gravity Screen, there's no need to even touch the device, as setting it face down will automatically lock it. Just set your smartphone down while you work and conserve a little battery life. Pick it back up and Gravity Screen will automatically flip on the display for you.

What makes the double-tap method useful is that it can be performed from anywhere on your device.

Who honestly uses their Google Now gesture? If you're like me and find this gesture useless, then change what it does. By assigning the screen-off action to the Google Now gesture, you'll be able to get some practical use out of this feature with a simple swipe up.
Pocket Lock has one of the most practical methods for locking your device: just place it in your pocket. Using the built-in gyroscope, the app will identify the position of the device in your pocket and lock it.
With this non-root take on the double-tap method, you will have the option to designate an activation area on your screen that can toggle the display off from within any application or screen.
There could technically be a #10 right now, but I assume you're all to smart for me to mention just going into the settings and using the time-out feature to automatically turn the screen off after a set interval.
