How to charge the batteries of smartphones and laptops, so they last longer
Tips Devices / / December 19, 2019
Modern smartphones and laptops are powered by lithium-ion batteries. They are not as picky as the old device, but still in need of proper operation.
1. Do not discharge the device before the end of
You You could hearThat the battery should be fully discharged, so that he did not lose the maximum capacity. Ostensibly device "remembers" how much energy you expend to the next connection to the mains, and in the future can not accommodate an excess of this measure. This phenomenon is called "memory effect" and it is typical for the old nickel batteries, but not for new - lithium-ion.
Moreover, the full discharge harms modern batteries, significantly reducing their lifespan. Below you can see a table of the relationship between the depth (Depth of discharge) and the number of discharge cycles (Discharge cycles), which maintains the device.
It turns out that the more the battery discharges, the less he is able to serve cycles. Organization Battery University, which explores the energy storage, recommends not allow the charge level falling below 30%.
2. And do not overdo full charge
Members often charge the battery to 100% in order to achieve maximum autonomy devices. Or, in the case of laptops, a long time do not isolate them from the sockets. In this operation there is nothing wrong, until it becomes a habit. If the battery level is too often reaches a maximum, it can accelerate the deterioration of the battery.
Participants Battery University gives the following comment on this subject: "Partial charging better full." According to their observations, the device need to be disconnected from the power supply to the battery is filled to 80%. If you recall the recommendation of the previous paragraph, we can formulate a simple rule:
So that the battery will last longer, maintain its charge at 30-80%.
3. But once in 1-3 months fully discharge and then charge the battery to 100%
This advice contradicts the previous two. But now we will explain everything. Laptops and smartphones on Android and iOS show the rest of the energy in the battery as a percentage or minutes and hours. After a large number of partial cycles of this counter may lose accuracy. But after calibration numbers on the screen again begin to reflect the real state of affairs. If you calibrate the battery every 1-3 months, it does not hurt him.
4. Avoid overheating
High temperatures adversely affect the battery life. The following label you can see the relationship between temperature rise (Battery temperature) and a decrease in battery capacity (Permanent capacity loss).
That is why it is important to ensure that laptops and smartphones do not overheat.
5. Properly connect the device to the mains
It would seem that what could be simpler than to put the gadget on charge? But there are some pitfalls.
For example, damaged or counterfeit charger is capable to damage the battery and the gadget as a whole. Not to mention the danger it poses to the people around them. Therefore, always use only serviceable and certified chargers from brands you trust.
Also, if you charge smartphones and other gadgets from your laptop via USB, it can create an unwanted burden on its battery. In order not to drain the battery thus, ensure that the laptop is plugged in and is not in sleep mode.
6. Charge your gadget by half, if you are planning for a long time do not use it
Let's say you're going away for a month or two out of the house and do not want to take all the gadgets with them. Then you need to properly prepare them for inaction. Apple and other manufacturers recommend in such cases, turn off the device, leaving the battery in about 50% of the charge.
