If you want to extend the life of your mobile phone, remember the 5 principles, the key is the method of charging your mobile phone. Are you doing it right?

Today's smartphones use lithium batteries, which are lightweight and fast to charge, but the battery capacity will gradually decrease over time. How can I extend the life of my phone battery? The key is whether the charging method is correct.

5 ways to extend the battery life of your phone !!
1. Charge your phone anytime, anywhere
The correct charging frequency is "a small number of times", and charging at any time, even if only a few minutes. Therefore, it is best to carry the charger with you.

2. Don't let the battery run out completely
In the past, old-style nickel-metal hydride batteries had a so-called "memory effect", so they had to wait until they were completely discharged before recharging to reach the maximum capacity. But today ’s lithium batteries do n’t have a “memory effect,” so you do n’t need to wait until they run out of charge. If you wait until the battery level is below 20% or wait until the battery is completely discharged before charging, it will easily destroy the chemical activity inside the lithium battery and shorten the battery life.

3. The power is maintained between 65% and 75%
Test experiments conducted by professor D. S. Kirschen and others at the University of Washington Seattle in the United States have shown that the power is maintained between 65% and 75% for a long time, and the mobile phone battery has the longest life.
Of course, it is actually difficult to do. You can settle for the next best thing, and keep the power between 45% and 75% as much as possible. In the worst case, it should not be lower than 25%. As mentioned earlier, do not wait until the battery is too low or completely empty before charging.

4. The power does not need to be charged to 100%
Lithium batteries do not need to be charged to full, as long as they reach 75% or 80%.
In addition, once the power reaches 100%, the charging plug should be unplugged immediately, so that the mobile phone battery can be kept under the high voltage state when charging, and the battery life can be extended.

5. It is best not to charge overnight
Lithium batteries charge quickly, and it takes about an hour from zero to full. The chip built into current smart phones has a protection mechanism. Once the battery is fully charged, the charger's current will stop flowing into the battery.
Therefore, if the battery is fully charged, even if the charging plug is not unplugged, no excess current will flow into the battery, causing battery damage.
But the bad news is that when the charger current no longer flows into the battery, the power will begin to drain naturally. At this time, the charger current will start to flow into the mobile phone until the power reaches 100%.
In other words, if you do not unplug the charging plug, the phone will repeat this process all night, which will cause the phone temperature to rise and reduce the battery capacity.
