Should I charge my phone when it’s fully charged or when it’s halfway charged? I finally figured it out

Charging a mobile phone is an everyday operation for us. Nowadays, smartphones need to be charged at least twice a day, or even more. Do you know what precautions should be taken when charging a mobile phone? In fact, we probably have heard some sayings, such as the mobile phone should be charged only when it is out of power, and it must be charged to 100%, which is good for the phone;

But there is also a saying that the mobile phone should be charged as it is used, and the power must be kept above 30%. Never charge it after it is completely exhausted, otherwise it will damage the battery. These two completely opposite opinions have troubled many users. How should we charge our mobile phones? Let's talk about this topic today.

Lithium batteries are widely available and can be charged at any time

Should the mobile phone battery be charged after it is used up, or charged whenever it is used? In fact, the key lies in the material of the battery. Currently, most mobile phones use lithium batteries. For lithium batteries, the battery life depends on the charging cycle. The battery is fully charged from 0 to 100% is considered a cycle. If the battery is used up and then charged every time, the charging cycle loss will undoubtedly be faster, and the battery life will of course be consumed faster.

This is reflected in our user experience, that is, the battery life is getting worse and worse. Even if it is fully charged, the battery life is far less than when it was first charged. Now mobile phone users should understand that for today's mobile phones, a good charging habit is to charge whenever you use it, rather than waiting until the phone is completely out of power before charging.

Nickel batteries are a thing of the past, no need for long charging times

Since mobile phone batteries now need to be charged as they are used, what about the saying that mobile phones should be fully charged before being charged? In fact, that saying has been around for a long time. Before the popularity of lithium batteries, nickel batteries were popular in the mobile phone industry. One of the iconic features of nickel batteries is that they have a memory effect. Therefore, at that time, mobile phones needed to be fully charged for 12 hours to activate the battery after they were purchased.

But the popular lithium batteries now have no memory effect, so there is no need to do this. And although current mobile phones have charging protection mechanisms, charging overnight will not have any effect. However, leaving the phone fully charged for a long time will also accelerate the loss of the battery.

Correct charging habits to extend battery life

Knowing that mobile phones now need to be charged whenever they are used, another question arises: How much battery should be left in a mobile phone before it needs to be charged? Regarding this question, mobile phone users have various opinions. Some people say that it is time to charge the mobile phone when the battery is half left; others think that it is time to charge the mobile phone when the battery is 30% left.

Now, many mobile phones will remind you that the battery is low when the remaining power is 20% or 15%. So when is the best time to charge? There is no standard answer to this question, but according to the prompts of the mobile phone, it is undoubtedly a correct charging habit to keep the battery power above 20% for a long time, which can help us extend the life of the battery.

Nowadays, the performance of mobile phones is getting stronger and stronger, and Android phones can be used for more than two or three years. Performance is no longer the key factor restricting the life of mobile phones, and the role of batteries has been highlighted. Sometimes our mobile phone performance is still sufficient, but the battery breaks down first, and we have no choice but to change the phone. From this point of view, extending the battery life undoubtedly means extending the life of the phone. How do mobile phone users usually charge their mobile phones? Do you charge them after use or charge them as you use them?
