How to charge smartphone`s battery smartly?

Science Says you have been charging your smartphone in a wrong way.

Yes, we know. Our smartphone batteries are bad because they barely last a day.
But it's partially our fault because we've been charging them wrong this whole time. Almost of us have many confusions about how to charge the batteries properly. So, after reading this post you are definitely going to know the smart and proper ways to charge your Smartphone, Tablet or Laptop batteries.
Many sites has suggested many tips and tricks on this topic. But many of the tips are wrong and they can damage your phone/battery or can affect the lifespan of the batteries.
Hence, I just ignored those sites and their harmful tips, instead I refereed the information provided by Battery-University. So, the tips in this post are mostly correct and safe.

#1 : Always use the Charger of Proper Power Rating

Use the charger whose Output charge is acceptable to your phone. (Always check the Output on charger which came along with your phone.) Also, use Quality chargers. Do not use cheap chargers or cheap USB cables.

#2 : Don’t charge your phone battery from zero to 100%

The rule with Li-ion batteries is to keep them 50% or more most of the time. When it drops below 50% top it up a little if you can. A little a few times a day seems to be the optimum to aim for. Experts recommend that you do a full zero to 100% battery recharge (a "charge cycle") maybe once a month only. This recalibrates the battery - a bit like restarting your computer, or, for humans, going on holiday! The same goes for laptops, by the way.

#3 : Don't let your phone Switch off completely. Recharge it again once battery level goes below 15%

#4 : Try to keep it Cool :-

Charge at a moderate temperature. Do not charge at freezing temperature. (See BU-410: Charging at High and Low Temperatures).Smartphone batteries are so sensitive to heat that Apple itself suggests you remove certain cases that insulate heat from your iPhone when you charge it. "If you notice that your device gets hot when you charge it, take it out of its case first." If you're out in the hot sun, keep your phone covered. It'll protect your battery's health.

#5 : Don’t charge the battery all the way to 100%, when you don’t have to

According to Battery University, “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” and wears it away in the long run. If you are trying to keep your smartphone charged all day, this may seem counterintuitive. However, you should be fine, if you plug in your smartphone whenever you can during the day.

#6 : Plug in your smartphone whenever you can

Don’t wait till your smartphone battery runs down out of charge. Charging them occasionally throughout the day can help the battery’s performance instead when they are empty. According to Battery University, charging your smartphone when it loses 10 percent of its charge would be the best-case scenario. While this may not be practical for many people, so just plug in your smartphone whenever you can. It is ok to plug and unplug it multiple times a day.

This not only keeps your smartphone’s battery performing optimally for longer, but also keeps it topped up the entire day. Further, constant top-ups also allows you to use features, like location-based features that use your smartphone’s GPS antenna that would you normally not use, as it can eat up your battery life.

More Tips :-


  • Turn off the device or disconnect the load on charge to allow the current to drop unhindered during saturation. A parasitic load confuses the charger. 
  • Not all chargers apply a full topping charge and the battery may not be fully charged when the “ready” signal appears; a 100 percent charge on a fuel gauge may be a lie. 
  • Discontinue using charger and/or battery if the battery gets excessively warm.
  • Apply some charge to an empty battery before storing (40–50 percent SoC is ideal). (See BU-702: How to Store Batteries.)
