One of the most sad moment for teenagers like us is when our Smart phone's battery is about to die.
There's no direct way of extending the battery life but yes there are certain ways by which we can assure that our battery gives us power for long.I will be illustrating those tips and tricks in this post.
1.SCREEN:
The biggest culprit or rather battery sucker is our smart phone's screen.It just squander our battery.Now what can we do to save the battery is
(a)AUTO-BRIGHTNESS
Never ever use auto brightness.There are two disadvantages of it;
First it uses the sensor to determine what level of brightness we want,so in short we are wasting more energy rather than saving it because we are using sensor.
Secondly,it always give us more brightness which actually we don't want.
(B)DARKER THEMES/WALLPAPER
Now you might be thinking that how could the theme/wallpaper of our mobile will help us to save battery.But friends it's true.It can make a difference.
To understand the difference,one must know the difference between AMOLED and LCD display(majority of smart phones are equipped with these two)
AMOLED stands for ACTIVE MATRIX ORGANIC LIGHT EMITTING DIODE
and LCD STANDS FOR LIQUID CRYSTAL DISPLAY.
I wont be giving you any technical knowledge about them but to explain in simple words just remember that in AMOLED displays(most of the samsung mobiles are equipped with that only)black is true black i.e. there's no back lighting for it.
While in LCD displays the black is true black i.e. it is lit up from behind(current actually flows from within the crystals to reflect us with black color).
So,moral of the story is that if you are owning an AMOLED screen smart phone the use dark(black) backgrounds.
(C)SHORTER SCREEN TIMEOUT TIME
Keep the screen time out time as short as possible,because if you aren't using your mobile phone then why to let it screen discharge your battery?
And when required you can increase the screen time out time.
2.KILL THE UNNECESSARY TASKS
Most of us do open the task manager frequently and swipe your fingers from left to right or vice versa to kill the tasks.And that is absolutely fine because why to waste the battery for the application you aren't using.
And those who don't do this,start doing it.It's gonna help you.
3.VIBRATE MODE
We keep our mobile at vibrate mode when we are at college/office and other places.But it takes more charge to vibrate than to ring.So when ever possible avoid using vibrate mode and if you are using your mobile very frequently then its better to prefer mute mode.
4.TURN OFF EXTRA SERVICES
Turn off Wifi,Bluetooth,Mobile data,GPS,auto-sync(your contact list is updated every fifteen minutes by this feature) like services as soon as you complete your work.
Ditch widgets you don't really need, especially those that are connected to the internet like weather widgets.
Also don't keep mobile data and Wi-fi simultaneously active because it's of no use.How can one simultaneously use both features.
5.KEEP YOUR APPLICATIONS UPDATED
Sometimes we get irritated by repetitive updates of applications we get now and then.But friends it's good to keep our applications updated because it contains improvement in terms of feature as well optimization of battery life.
Change your Google Play Store settings to manual update your apps. If
you have the Play Store set to auto-update, you might have fifteen apps
updating when you least expect it, destroying your battery life (and
data plan) without you realizing it.
Hope above tips may help you keep your battery life little extended than before.
For example, you've got a hilarious pictures that you would like to share with your whole gang that is connected with your desktop (simply who is on your Skype contact list) or if you are on Skype call with your colleagues and want to explain a concept or show something like an important upcoming event and just want to show them what you mean instead of explaining everything.
