How to Increase Performance of Smartphone Battery

Today smartphones are using lithium ion batteries not suffering from memory problems of older nickel cadmium and nickel-metal hybrid batteries. Lithium ion batteries count charges differently than older. Therefore no need to worry about discharging of a battery.        

Apple explained it

Charge your Apple lithium-ion battery whenever you want. There’s no need to let it discharge 100% before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle. It could take several days to complete a cycle. The capacity of any type of battery will diminish after a certain amount of recharging. With lithium-ion batteries, the capacity diminishes slightly with each complete charge cycle. Apple lithium-ion batteries are designed to hold at least 80% of their original capacity for a high number of charge cycles, which varies depending on the product.

 

Battery Calibration

To maintain a State of Charge (SOC) mismatch.

Whenever an SOC mismatch occurs, i.e., sometimes you may notice that as soon as you plug-in to charge your mobile after reaching low battery state, in minutes, you'll notice it is 100% charged, but still in reality it wouldn't even have reached a half charged state. As soon as you begin to use it, it will soon again reach the low battery state. Sometimes, it may be the other way around. It will display as less charged, but will stand for a longer time. This is State of Charge mismatch.

No matter how well you take care of the battery, its capacity will still decrease as a result of unavoidable factors like typical usage, age, and heat. If the battery isn’t allowed to run from 100% down to 0% occasionally, the battery’s power meter won’t know how much juice is actually in the battery.

Manufacturers generally recommend calibrating the battery every 2-3 months. This helps keep your battery readings accurate.

So,

When do you Calibrate your battery?

Every once in 30-40 charge cycles or whenever you feel the battery's stand by capacity has much degraded in a very short time.

What happens when you Calibrate your battery?

The battery's charged percentage comes actually in sync with your absolute charged state.

How do you Calibrate your battery?

1.   Fully charge your battery, with your phone turned on.

2.   Turn it off and leave it plugged in for sometimes (ensure it is still fully charge, may be through LED notification light).

3.   Unplug it and use the phone till charge drops to 0% and it turns off by itself.

4.   Reconnect charger, turn it on back again and let it charge to 100%. You are done with the calibration.

But I want to tell you that today there no need to calibrate the batteries because today we have smart batteries with built in a digital calibration tool. By calibration you lose charge cycle which reduces your batteries cycle life. Better way to use mobile between 40% -80% battery charge statics.

Many times we say that by keeping phone to charge for whole night diminishes battery life by overcharging but that is not happening today because charge and battery are so smart to do that business.

QUICK, FAST , RAPID, TURBO Charging Means

Quick charging allows you to dump a lot of power into your battery by using higher-than-normal voltage. It takes less time than normal to charge your mobile. It depends on charger specification and your battery.

According to Qualcomm, in a 30-minute test a traditional charger (5V, 1A)[5W] managed to power a battery up to 12 percent, while the first generation of Quick Charge(5V 2A)[10W] managed 30 percent, and Quick Charge 2.0 (9V, 2A)[18W] filled it to 60 percent in 30 mins.
