Ever Wondered What’s The Best Way To Charge Batteries According to Science?


Whenever my phone battery dies quickly, I tend to blame the phone manufacturing companies a lot. “This company doesn’t know how to make batteries”, “I need to change my phone”, “This phone has a very short life span” are just a few of those reasons. I am sure many of you do the same, but surprisingly, battery issues are entirely our partially our fault. Nobody likes to blame themselves but that’s the harsh truth.

One common mistake that most of us make is that we charge our phones when they are almost completely dead. We tend to believe that if we charge our phones in short bursts, our phone battery gets damaged quickly. A site from the battery company Cadex, Battery University gave a detail view of how the batteries get damaged. According to this site, smart phones, like humans are also sensitive to stress and extended periods of stress can deteriorate the battery’s life.

This implies that if we want to have a healthy battery and use our phones without worrying about the battery life, we must change a few things.


Never keep the phone plugged when it’s fully charged

We often tend to forget to unplug the phone when it gets fully charged. This happens often to me when I charge it overnight while I sleep. Well, apparently, it’s pretty bad for the battery. Battery University stated that the phone is kept plugged despite the full battery; the battery gets worn out in the long term. Why? Well, according to the battery university, after the 100% charging is done, ‘trickle charges’ are generated.

hese charges create high stress and high tension in the battery that wears it down slowly. : "When fully charged, remove the battery. This is like relaxing the muscles after strenuous exercise." Well the next time you plan on charging your phone overnight, just imagine doing exercise all night. Well that’s something we wouldn’t like right?

Change of plans; DON’T try to charge it to a 100%

According to what the Battery University stated, this 100% charging seems to be a bad idea. “Li-ion does not need to be fully charged, nor is it desirable to do so. In fact, it is better not to fully charge, because a high voltage stresses the battery"
What if we want the phone charged all day? Well, try to plug it in whenever you get the opportunity during the day instead.

Get the phone plugged in multiple times instead

Big charging sessions seem to be bad for the health of a battery, smaller charging sessions work better. The more I think about it, smart phones’ battery works like our metabolism. Smaller eating sessions throughout the day increase the metabolism and a larger eating session once a day decreases it. Our phones are definitely ‘SMART’ then.

According to the Battery University, it is okay to plug your phone multiple times a day. This apparently keeps the battery performing better throughout the day. Well, who knew being counter-intuitive helped. Another interesting thing is that these periodic charging sessions, enable us to use apps and features that we hate using due to their battery life ‘eating’abilities.

Let them keep their cool

It is extremely important for the health of a battery, that they remain cool. Apple suggested the same. "If you notice that your device gets hot when you charge it, take it out of its case first." If you are out in the sun, keep your phone covered to protect it from the sun.
All this is making me realize that smart phones are almost as sensitive as humans. Well it’s about time I realized this, I better go unplug my phone. It’s still on charging.
