We are all charging the phone the wrong way

Some experts of Battery University said that most users are still charging the phone battery the wrong way.

Most people are charging the phone the wrong way

How to charge the phone battery properly and best suited to today's electronic devices is always an extremely difficult question to answer because it depends on how much the user feels.

Until now, people still conceive that phone batteries should not be recharged and recharged many times but should only be used when the battery is about to run out before it is fully charged and used, but according to many experts on Li-ion battery research. This is very anti-scientific.

Recently, Techinsider technology specialist has had an article about battery charging technology products today. According to the analysis given by this author, most users of technology products don't know how to charge Li-ion batteries that are very popular on today's technology products. Or use a method to charge Ni-Cd batteries for charging Li-ion batteries.

Based on the battery analysis of a battery manufacturing company, Cadex, the company said that most users of computer phones have misconceptions that make devices' battery life significantly reduced according to time.

Mistake 1: Plug in the charger again when the battery is 100% full

The company said that for Li-ion batteries, users should not continue to charge when the battery is full, because when the battery has reached 100% of charging, it must continue to maintain a very low charge current to keep The battery is not dropped when plugged in, they call it "trickle charging" . This type of charger will cause the battery to switch back and forth between the two charging and discharging states continuously, causing the battery to be severely stressed affecting the chemicals in the battery.

The withdrawal of the charger after being filled like a person relaxes his muscles after a stressful working day, the withdrawal of the battery will help the battery chemicals to be stabilized in a state and difficult to age.

Mistake 2: Fully charged up to 100%

In fact, Battery University's research (a synthesis page on the wrong knowledge about batteries built by a battery manufacturer) shows that Li-ion batteries are not needed or should be fully charged by 100% by Perhaps, theoretically Li-ion batteries will gradually increase the voltage from 3.8 to 4.2V after being fully charged, but the higher the voltage, the faster the chemical in the battery will react, leading to rapid aging. chemistry than low voltage.

It is for this reason that Li-ion batteries are expected to have the highest life expectancy when maintaining the battery level at <100%.

Mistake 3: Charge a circuit until the battery is full

It is not necessarily a concept, but it is a habit of smartphone users to lighten up the phone to charge for charging to light. It is quite suitable for the schedule of most users. In addition, many people still believe that Li-ion batteries have a fixed number of charges and that each time a user unplugs the charger, it will count as one charge, thereby reducing the battery's life by a fraction.

But as mentioned above, Li-ion batteries are very sensitive to the big changes in electricity and experts at Battery University found that the way of charging helps the most durable Li-ion battery to be charged. every time it lost 10% of the capacity. And also, there is no story that every time the charger is unplugged and the battery plugged in again, it will be counted as 1 charge. If you do not believe you can see the number of cycle count on your iPhone device in this way to see if the number of cycles count increases as rumored?

But obviously, this charging method is not suitable for today's phone use habits because no one takes time to charge the phone 1 time 1 time. Therefore, experts recommend that the battery be charged continuously during the day as soon as possible, charging the battery into a few tens of percent each time will make the battery work more durable than using a battery and charging 1 the circuit comes full.

The continuous charging of the day is not only to protect the phone battery, but it also helps users not to worry about battery capacity when leaving the office. In addition, the excess energy will help you to comfortably turn on all the features that you normally turn off just because it sucks the battery too horrible such as 3G and GPS services.

Above are some ideas on how to charge the phone battery and the computer provided by experts from Battery University to help Li-ion batteries have the highest durability. But in fact, we are continuing to charge the battery in the usual way and there are still not many people complaining about the battery quality on new smartphones.
