when it comes to battery drainage there are 'kingpins' and here they are:
-Vibrations and unnecessary sound
-Android phone screen and Animations
-Wifi(many people are guilty of leaving this on)
-Tethering Hotspot
-Hepatic Feedback on screen/button press or tap
-3G/4G networks
-Battery saver Apps(surprised)


directly or indirectly they make sure your phone's battery doesn't last long but there are little tricks/settings you could apply to extend your phone's battery life;

#1. How to mange Vibrations and sounds to save android battery. Talk about vibrations and sound, these two should work in alternation especially when it comes to incoming calls,of what use is the vibration if your android phone can ring out loud? Just turn it(vibration) off please and save that battery life, in any settings where ringing is required turn your vibration off be it alarm, incoming call, whatsapp chat text and every other.Now sound on key press is annoying and also lends its little hands in making sure that android battery doesn't last long, put it off.

#2. Android phone screen also drains your battery life; ahuge chunk of the battery power is used up by the screen especially on high-end android devices, but you can't do without it right? There's a little trick, reduce the brightness of your screen to the minimum you can. Animations like live wallpapers and animated 3D wallpapers should be banned with immediate effect from your android, they don't let your battery last long.

#3. WiFi, when ever you're not making use of your phone's WiFi just put it off, the hardware would keep draining your battery while its on because its always searching for hotspots. funny, many people leave their's on and still complain of low battery life.

#4. Tethering Hotspot, as you know this feature on your android enables you to share your phone's internet connection with other devices, it appears to be a nice feature but this is very dangerous to your battery, not just your battery's performance but its life span also, it actually damaged my phone's battery. One advice, if your phone has a non-removable(the worst thing that happened to smartphones) battery just stay away from this feature till you're done with that phone, should yournon-removable battery gets damaged, you know the rest.

#5. Hepatic feedback is the vibration you get from your android device when you tap an option, should be disabled for better battery life.

#6. 3G/4G capability on your android smartphone is nice but becomes bad when you're in an area with no 3G/4G reception as a result the chips would strain more and drain more battery in a bid to get you connection tothe nearest, when ever you're in such areas kindly switchto 2G it saves battery and good for chatting and text messaging.

#7. Battery saver Apps, am I serious? absolutely!. These apps and many other background apps are part of the cause of your low battery problems. How can an app that stays on 24/7 save battery?Trust me, it drains more battery than it saves, don't be deceived. I don't use them so I won't advice you to.


Asides draining battery some of these also damage the batteries entirely, here;

excessive use of the Wifi, 3G/4G and mostly Tethering hotspot(Everybody run from this!)

just doing these would reduce the rate at which your phone's battery goes down.
