And now here comes the point of power consumption.Laptop charger consumes more power than ,mobile charger because laptop requires more voltage and battery of laptop is big as compared to mobile.It is true that it does not make big difference for personal level but it makes a big difference if we view it on national level and worldwide level.

So, how to efficiently use mobile phones and laptops as alternatives to save power consumption and increase comfort.As we know mobile phones have converted into "Smart Phones" which provide smart features now, you don't need to open your laptop or computer for simple uses such as to view mails,use social websites and many other features but most important feature is that,it is on the go means"Whenever you think you can do" because it is in your hand.

Even for coders there applications  are also available to compile code in mobile phones. So you don't need to open  computer to compile small code but for larger code you have to.
Even you can also play high resolution graphic games on tablets or mobile phones.
So, if we use mobile phone or tablets for our little use then we can save lot of energy of our city,our Nation and our World.And as we all know "Save Energy Save Money".

Now,mobile application market has become so vast you just think and application is available to use,

Stop Google and Other Services From Tracking Your Location

Apps and many other services keep tracking all your move and this serious privacy issue. And it also more battery than ideal situation. So ,if you don’t want services to track you, disable location tracking on your devices.
When you're using a map app to find your way around, or if you want to check in to a location on Facebook to tell your friends where you have been; then location tracking is useful and seems benign.
Google
You may not know it but Google tracks your location history unless you disable it yourself. It gathers this data from your usage of Google Maps. You can disable this, and even manually delete certain places from your location history. Here's how.
1. Go to this Google settings page.
2. Click the Pause button in the "Places you've been" tile on the right. To delete individual entries from location history, click Manage history.
3. You can pick any date from the calendar on the left > click Delete all history from this day. If you don't want any of your location history tracked, just click Delete all history.
Android
Turning off location settings on your Android phone is pretty easy, but it can affect the functioning of some useful services. Google Now for example relies on location data to provide you information you need without you even searching for it. If you still feel that you'd rather not report your location to Google, follow these steps.
1. Open Settings > scroll down to Location > Google Location Settings.
2. Now tap Location reporting > Off.
3. Go back, tap Location history > Off. You may also want to tap the "Delete location history" 
button below.
iOS
Several apps and system services use your location on iOS to provide features such as apps popular in your locality and even to serve advertisements based on the place you are in. Here's how to disable all of that.
1. Open Settings > Privacy > Location Services.
2. The first option is to turn Location Services on or off. You can turn it off to disable tracking entirely, but that will mean that you will have to do several things, such as search for weather data, manually.
3. Scroll down to see which apps have access to location data. You can decide which apps don't need it and turn it off for that app. If you have Find My iPhone/ iPad enabled, we suggest you don't disable location tracking for that because it may help you locate your device if you lose it.
4. Scroll down to the bottom and tap System Services. Here you can disable all options except Cell Network Search to stop tracking. Tap Frequent Locations and turn that off too.
Windows 8
Disabling location tracking on Windows 8 is quite simple. This is how you do it.
1. Hit Windows key+C > click Search > type PC Settings in the search bar > click PC Settings.
2. Go to Privacy > Location > Let Windows and apps use my location > Off.
BlackBerry 10
The BB10 operating system makes it easy to prevent tracking. Just follow these steps.
1. Open Settings > scroll down to Location Services > turn off Traffic Data Collection and Location-based adverts. You may turn off Location Services entirely in the same place.
2. If you just want to disable location access by specific apps, go to Settings > App Manager > tap "Go to the Application Permissions screen to change permissions for individual apps".
3. Now tap Permissions > select Location > tap any app that you want to cut off from using your location > Off.
That should have helped you disable location tracking on any device. If there's any other way to disable location tracking that you prefer, let us know with a comment.
Web Browsers
If you use a desktop or laptop to browse the Internet, you can disable location sharing in your Web browsers. Note that websites may still be able to identify your location using your IP address, but they will find it much harder to zero in on the place you're browsing from. Here's how you can disable it.
Google Chrome
1. Click the Google Chrome Menu icon (three horizontal lines) > Settings.
2. Now scroll down and then click on Show advanced settings >
Content Settings 3. In the pop-up, scroll down to the Location section > Do not allow any site to track your physical location.



Mozilla Firefox
1. Type about:config in the address bar > hit Enter > click I'll be careful, I promise.
2. Search for geo.enabled and double-click it to change its value from 'true' to 'false'. This will disable location sharing.

Opera
1. Click the Opera button on the top-left > Settings. Alternatively, you may use the Alt+P keyboard shortcut.
2. Click Websites on the left sidebar > scroll down to Location > select Do not allow any site to track my physical location.
Safari
1. Open Safari > Preferences > Privacy.
2. Click Deny without prompting.
Internet Explorer
1. Go to Tools > Internet Options, or use Alt+X.
2. Click Privacy > check Never allow websites to use your physical location.
Windows Phone
There isn't one place where you can easily disable specific background tracking without disabling location services entirely in Windows Phone. Here's what you can do if you don't want to turn off location services.
1. Head to Settings > swipe right to Applications.
2. Manually open each app here and disable location wherever it is an option.
3. Swipe left (back to System) > WiFi > Advanced > uncheck Send information about WiFi connections to help discover nearby WiFi.
4. Head back to System > Feedback > Off. You can also go to Settings > Find My Phone > Off but that is a useful anti-theft feature that you may not want to turn off.

For a more thorough option, open Settings > Location > Off.

That should have helped you disable location tracking on any device. If there's any other way to disable location tracking that you prefer, let us know with a comment. As always, our 
How to sectionwill help you find more useful articles.
