Does the phone be fully charged before recharging?

How do you generally charge your cell phone? Do you charge it when the battery shows 10% capacity or when you have spare time? A lot of people ask whether charge cell phone battery after running out all electricity, or charge any time you like.

01

Now use lithium battery, there is no battery memory effect, increases with the increasing charge.

The use of mobile phone battery, a lot of people wrong, cognitive also stay on stage of nickel cadmium battery.

We first give some electrical charge, you need to run out of electricity recharging, because when the battery technology is not developed, the most commonly used electrical appliances is one of the traditional nickel cadmium battery, the battery memory effect exists.

So-called battery memory effect, is refers to the battery will memory user daily charge and discharge rate and the mode, time is hard to change this pattern, can no longer do greatly charging or discharging.

So the use of the nickel cadmium battery is very trouble, such as used for the first time need to be "full charge and discharge cycle" two or three times, in order to activate battery capacity. In use process, both cannot be put in charge, also can't just pull the filling.

In mobile phone use is up to now lithium battery, compared with the previous rechargeable batteries, lithium battery no memory effect, can increases with the increasing filled with completely.

02

Cell phone battery is not durable in winter, with broken?

In the winter, we often found that the battery is not durable. If we literally charge, the battery is broken.

After the above explanation, we understand that the use of lithium-ion batteries is no threshold. Why winter mobile electric soon run out?

In fact, winter low temperature, battery performance is normal, durable battery in winter is generally not summer.

Its principle is: is to rely on chemical reactions within the cells work. Winter temperatures, charge and discharge of electrochemical reactivity is poor.

Due to the lower temperature, ion diffusion speed is slower; And at low temperature, battery internal resistance will be high; The lower the temperature, the cell membrane permeability is poorer.

Comprehensive these reasons, so the battery is not durable winter is normal, after winter, the battery will become durable again.

03

When need to change?

Although lithium battery can use, but cycles above a certain figure, battery performance will continue to discount.

Mobile phones in circulation after 500 times to charge and discharge, battery standby time will fall. So we used two years in the mobile phone, and it will feel the battery is not durable.

Note that if we are from mobile phone charger from 50% to 50%, this is not a full charge, is only half a second. So everyone is at ease with filling in.

All in all, in the case of charging every day, mobile phone batteries in the use of two years later will have performance degradation, so recommend to change a cell phone in two years.
