For many users of Android, The belief is that their Phone battery is a
little bit better than the Blackberry Phone Battery but i guess they
don't have idea that an Andriod Battery can last upto 72 Hours if you
take some certain precautions.
The ‘promise’ by most App developers to make sure users download apps
that do their phones no good at all than lies that their Phone Battery
will last longer. Instead, they end up knocking down the battery the
more and bombarding users’ screens with unsolicited ads.

I will reveal to you some simple practices we keep overlooking, that
can improve your battery life without requiring any software:
1. Pay attention to your Network Bars
To stay connected onto a network, mobile phones establish and maintain a
continuous communication line with the nearest telecommunication mast.
Whenever they are near a mast, mobile phones use less power to establish
this communication thus the battery is never strained. However, when
moved further away from masts, mobile phones usually struggle to
establish communication with the tower, thus straining the battery and
sometimes resulting in their heating especially when the phone is kept
inside trouser pockets.
The point of advice here is that whenever you are far away from
telecommunication masts and your signal strength becomes weak e.g. in
remote areas or underground buildings, it is wise to switch off the
phone to preserve power.
2. Keep Screen Brightness to a minimum
If not adjusted, the screen is likely to hog more power than any other
‘department’ in your smartphone. As app developers win their quests to
keep us glued to our screens by cleverly creating fascinating apps, we
as users continue torturing our batteries without knowing. Don’t be
frightened though, you won’t be summoned in front of a judge for this.
Just remember to always set your brightness to minimal levels to enjoy
more runtime hours from a single charge.
Low screen brightness also minimizes overheating of the battery caused by rapid drainage of power to light up the screen.
3. Observe strict charging cycles
Today, many users forget to charge their mobile phones properly. It is
inappropriate to ‘Whatsapp’ or tweet endlessly with your phone glued on
the wall charger and claim you are charging it.
Plugging in the charger with a half full or even 1% full battery is imprudent.
The recommended time to charge a battery is when it cannot power up
the phone; plug it in and give it all the time it needs to fill up
before using the phone. This routine has been proven to increase battery
efficiency as well as lifespan.
4. Keep your phone in a cool dry place
Trouser pockets, jam-packed handbags and sweaty palms are the last places every phone dreads to be.
Heat, pressure and being flung around are as nauseating to mobile phones
as is to humankind. Body heat and pressure from trouser pockets causes
the battery to warm up therefore lowering its efficiency.
When sweat finds its way beneath the back plate to the battery pins
and phone motherboard, it not only causes rapid discharging but also
might lead to short circuiting and rusting.
For gents, it is advisable to carry your phones in shirt pockets,
coats or porches that can be attached to the belt. Ladies should avoid
carrying mobile phones engulfed in their palms or stuffing them
alongside other personal effects in handbags.
Conclusion
Observing these basic guidelines will not only increase the battery life
of your smartphone but also protect you from potential accidents such
as explosions caused by distressed batteries.
