How to maintain your smartphone and laptop battery

Those who bought a new mobile phone, a new notebook, are often particularly concerned about batteries, especially notebooks, like using a variety of software to see the battery loss. This article would like to briefly introduce some of the ways I know how to use and maintain lithium batteries. Physics is not very good, and all of the following statements are judged by reference.

First, a common misconception:

Full fill three times, charging 12 hours, deliberately full put, are the way to damage lithium batteries, these are Ni-mh batteries.

The charging circuit will stop charging until it is filled with lithium-ion batteries that are still plugged in.

The side of the charging side of the work on the lithium battery is not very small, the reason is not recommended side-filled work because of high temperature environment on the battery damage. It may be beneficial to remove the battery unless the laptop is high in temperature every day. In general, there is no problem with edges.

The correct way to use is to charge at any time, want to use, avoid over put. Of course, if possible, there are some benefits to following this approach:

Shallow filling. That is to say, the discharge and the degree of charge is not too big, so the condition allows the case to recharge conveniently is a good habit.

Avoid heat.

Avoid overcharge and excessive discharge. Because lithium-ion batteries have protective circuitry, this will not happen in general. Except for a long time, it may be over.

What do you have to do for a long time?

The amount of electricity in the 40%~60% is preserved.

Try to save in low temperature environment.

In addition to the problems related to Chargers:

Nowadays, there are few power management ICS on the charger, usually on the lithium battery or equipment. So the charger can be recharged as long as the voltage is met.

As for the nominal current of the charger, on behalf of the output power of the charger, how much is controlled by the power management IC, so the power size will only affect the charging speed, the use of more than the equipment required high-power charger charging, will only be based on the device's power management IC settings to charge, usually will not charge fast. In particular, it is no problem to charge the IPhone with an iPad 10W charger. Both the Apple Web site and the resources provided below are answered and validated.

Charger voltage is generally higher than 5V, floating 0.2V does not matter, by the power management IC control provided to the battery voltage.

Try not to fill the seat, this is because the market is not good for the Almighty. For more information, see Resources below.

IPad charging is high, on the one hand requires a 10W power charger to reasonable time to charge (otherwise too slow), on the other hand, Apple's charger USB interface with an additional identification resistor. Without this identification resistor, the IPAD may show "no charge".
