- Requires charging up to 50% every six months.
Smartphone: Many people think that if the smartphone is switched off completely then its battery will not be consumed at all. But it is not so at all. Actually, even when the phone is switched off, its battery keeps decreasing gradually. If you have ever switched off an old phone for months and switched it on again, you must have noticed that its battery is not as good as before. Why does this happen? Let us know why this happens.
Why does the battery drain even when the phone is switched off?
For your information, let us tell you that after the phone is turned off, the screen, internet and apps stop working but the use of battery does not stop completely. The biggest reason for this is the natural process of lithium-ion battery which is called self-discharge.
Let us tell you that in this process the battery keeps losing its energy gradually even without any use. The battery of a normally switched off phone can reduce by about 1 to 2 percent every month. If the phone is kept in a very hot place then it can discharge more quickly.
Clock and Wake Circuit are also the reason
Actually, a small electronic circuit inside the phone is always active. This circuit helps in turning on the phone as soon as you press the power button and also plays an important role in maintaining the correct time and date when it is turned on again.
This circuit consumes very little power but if the phone is switched off for a long time, its effect becomes visible on the battery percentage.
Why does leaving the phone on drain more battery?
For your information, let us tell you that even if the phone is on, even if you are not using it, many things keep on consuming the battery.
- Apps running in the background
- Mobile network and Wi-Fi connection
- notification system
- Other system processes
This is the reason why a phone kept on without being used for several days can discharge quickly whereas the battery of a switched off phone degrades more slowly.
What to do if you have to keep the phone on for a long time
If you have bought a new phone and do not want to use the old phone for several months, then it is important to store it properly. Experts advise that the phone should not be stored with a fully charged or completely empty battery.
If you want to store the phone for a long time, then the phone should be kept charged till about 50 percent. Apart from this, every 5-6 months the phone should be taken out and charged again to about 50 percent. This keeps the battery in good condition.
Why battery should not be completely discharged
Let us tell you that if the phone remains lying with a completely empty battery for a long time, then it goes into the state of Deep Discharge. Now in such a situation the battery power may reduce forever. In many cases, the battery starts providing less backup than before and in the worst case, the device also starts getting damaged.
How to store battery for a long time
If you are going to keep the phone switched off for a long time then these things should be kept in mind.
- Turn off the phone at about 50% battery.
- Recharge it every 6 months.
- Do not keep the phone completely discharged.
- Also avoid storing it for months by charging it 100%.
- Always keep the phone in a cool and dry place.
- Excessive heat can rapidly reduce battery life.
