A lot of people nowadays have smartphones. The majority of people I know who have a smartphone have one with some version of Android operating system. Most of them have had some regular phone with a factory OS and Java ME for running applications and extending functionality, but most of those applications work only when the phone is on and when they are in focus. Obviously, there were exceptions.

Today’s modern and smarter phones have processors many hundred times faster than those old ones, they have many thousand times more memory and even up to ten times the capacity of their batteries compared to those older ones. Screens are also bigger, brighter, more colourful with a much faster refresh rate, enhanced motion picture dynamics etc.

Even though these new phones have bigger and better batteries, they still last up to two days when used “normally”, while our old phones used to last for days. I remember how my old Nokia 3510i used to last for at least 5 days when it was new and I was really draining it with WAP Internet, downloading and trying out all sorts of JAR programs, games etc. So, it wasn't just lying around there on the desk and periodically calling for the base cell. It was really working hard.

Today’s phones work much harder. Even with all their new “powers”, they still can’t keep up with our demands.

“Check this, check that…”

“Update the weather info every half an hour, update my calendar, update my Facebook feeds, my Twitter feeds, sync my messages, sync my pictures, etc.”

“Stay on-line on WhatsApp, Viber, Skype, Google Talk etc.”

All of these activities require a lot of energy, processor time and all that comes from a single battery about ten times more powerful than the batter that used to power our old phones for days without this kind of usage.

Clearly, our demand for information has made these little slaves of ours to work themselves dry of juice much faster than we would like them to. However, we can’t really do much if we really need all this information being constantly communicated to our phones even though we get to notice only a small fraction of all they gather for us, but if we don’t really read all that information, if we don’t really review all posts our friends tweet and send to their walls and if we don’t really check the weather forecast every half an hour, we should think of giving our little helpers some time off or at least giving them a break when we sleep.

Yes, that’s right! They work even “when we sleep”.

Some phones are smarter than others and they “sleep” when we do (or at least when we should), but most of them don’t. Most phones work with the same eagerness day and night. They keep downloading information, they keep synchronizing our data, they keep checking for on-line messages, calls, important updates, scheduled task alarms etc. They never stop.

Why not turn off the Internet when you go to sleep, get an app that will disable syncing and updating on one click, and enable them with another. This way, you would click one button to really put your phone to sleep before you turn in for the night and in the morning, wake it up and ask it to get up and running while you have a cold shower, wash your teeth, have a cup of tea or coffee and then check what news it has gathered for you.

Oh, and make sure your notice that you won’t have to recharge your phone every night, but every second night or more. This also prolongs the life expectancy of your small pocket assistant.

Don’t forget! When you sleep, your phone works. Why not let it rest too, like you do.
