you're wrong! sometime your tablet left 80% battery life u keep it on?
Tablet just like your life, can u without sleep within 1 month?
If you always keep your gadget On sure your gadget life is shorter than other!
another wrong perception.
If your tablets takes up 20% battery over night. That means you are running something in the background. You should also turn off bluetooth, 3g/edge, wifi and so on it you don't need them to be running at night. Or the tablet is just lousy. Majority of the phone or tablet's battery usage is on the screen. When it is in sleep mode, screen is blank and battery usage would be at minimum.
Tablet need to sleep? Yeah...sleep is not equal to power off. When you leave it idle, it go to sleep.
Tablets/smartphones are designed to turn on 24/7 under standby mode. When you say gadget's life become shorter, do you mean the battery or other parts? If you mean battery then you are wrong again. Modern ion-lithium battery does not have "memory effect" when it comes to keeping charge. It is designed to last around 2-3 years. Even if you turn the component OFF, it will still last that long only. It doesn't help to prolong the battery if you always keep your device OFF.
