How to calculate the life of mobile phone battery How to calculate the life of mobile phone battery

   Nowadays, lithium batteries and nickel-metal hydride batteries are commonly used in mobile phone batteries. With the increase of service time, the life of batteries will gradually shorten. So how to check the remaining life of batteries, How to calculate the life of mobile phone battery? ? Here is an introduction for everyone.

How to calculate the life of mobile phone battery?

  Many friends think that the more times a mobile phone is charged, the worse the battery will be, which makes sense. However, the most accurate definition of battery life is that the number of charging cycles determines battery life.

  I’m sure many friends don’t know how to calculate the number of cycles. In fact, a cycle is a cumulative complete charge+a cumulative complete discharge. For example, if your mobile phone has a battery of 5000mAH, then every cumulative charge to 5000mAH is a complete charge process. If each charge is 500mAH, then it takes 10 times to complete this charge procedure, and the same is true for discharge. The actual situation is that you can only consider a cycle after multiple charge and discharge operations.

  The average cell phone battery cycle is about 500 times, which is actually quite durable, but many friends are worried that after 500 times, my cell phone will be scrapped, and I don’t want to change it! In fact, the number of times the mobile phone runs out of cycles means that your battery is only 80% of its previous capacity, and the subsequent charging process will consume the battery capacity faster, but the battery is still operating normally. When the battery life is drastically reduced or turned off for no reason, you need to consider replacing the battery or the mobile phone.

  That’s what I introduced How to calculate the life of mobile phone battery, I hope it helps you.

Some things you must know about shooting.

Hello, everyone, today we share some things you must know about shooting, I hope you like it!

front cover

There are no rules for shooting. The purpose of shooting is not to be beautiful, but to score. If you hear shooting, you think that shooting is limited to your feet. That’s because we have a preconceived concept of shooting. In the past, some strikers that everyone liked, Mueller, Inzaghi and Raul, didn’t shoot well, but they just scored.

Figure 1- Prejudice

This doesn’t mean that we don’t have to pursue technical perfection, we must do it well, because if we really want to shoot, we must score, exert ourselves, turn the corner and shoot the ball where we want to shoot.

Figure 2- Shooting Score

However, we have said the perfect technique countless times. Put our supporting feet next to the ball, head down, tighten the core, pay attention to follow the ball, lock our ankles, and then kick the ball and land, like this.

Figure 3- Perfect Technology

But if we look up like this, or lean back, we will send the ball directly to the moon, which is definitely not what we want.

Figure 4- Don’t lean back

So what’s so special about these strikers mentioned above? They know where the ball is going, which is another form and part of shooting, because in essence, it is why we shoot, and we shoot to score.

Figure 5- What’s so special?

Think about it, if we know where the ball is going, we can shoot it in. Sun Tzu, a great thinker and author of Sun Tzu’s Art of War, said, "If you defeat the enemy without fighting, the good will be good."

Figure 6- Know where the ball is going

This means that we must find a way to achieve our goal instead of struggling like ants on hot bricks.

So whether you like him or not, Ronaldo can always score goals. He doesn’t care about those comments. If we want to win and score goals, look at what these players are doing.

Figure 7- Always scoring goals

Harland has many chances to shoot. He knows how to score goals. What else can we do?

Next, the most important thing is that we should take risks. In some leagues, the goal rate of shooting rebound is as high as 20-25%.

Figure 8- Dare to take risks

This means that if we shoot, although it doesn’t look the best, as long as the ball can pass the first defender, who knows what will happen?

Figure 9- Passing the defender

Rebound ball is difficult for the goalkeeper to predict and react in time. Maybe the ball will bounce in from the knee, back and face. Anyway, we will never know until we try.

Figure 10- Dare to shoot.

Remember, as a striker, we should dare to take risks, and as a defender, we should also dare to take risks, but we should take risks wisely, especially when we are in and around the restricted area, and don’t hesitate to shoot decisively.

Figure 11- Decisive shooting

That’s all for today. Please continue to pay attention to the road of football for more exciting football teaching!

So the hotel attendant went to the passengers upstairs and told them to keep their voices down. However, it didn’t take long for the passengers upstairs to start noisy again. The passenger was very angry, so he called the waiter and said, "Can you manage the passengers upstairs? I have to sleep tonight! "

The waiter replied, "I’m sorry, sir. I’ve already told the passengers upstairs, but they continue to make noisy noises." I’ll talk to them again. "

After a few minutes, the waiter came back and told the passenger, "Sir, the passengers upstairs said they didn’t mean to, because their room was too hot, so they turned on the air conditioner very loudly." They have turned off the air conditioner now. "

The passenger was satisfied and said, "OK, can I go to bed now?"

The waiter replied, "Sir, you can go to bed. But if you hear any noise upstairs, please don’t call us. We have tried our best. "
