Why can't the current mobile phone reach a long battery life?

Today's smart phones are so powerful that it is hard for us to imagine the speed of updating. It is an indispensable thing in our pockets. However, the power of mobile phones is something we must consider when going out. If the strength is insufficient, it is useless as an ornament. We can see that charging treasures appear in front of many merchants in various stores and supermarkets, just because the power of smart phones is a big problem.

We can always hear the voice of the merchants in the advertisements of various mobile phones? Charge for five minutes and talk for two hours? In fact, the emergence of this slogan is also the demand of manufacturers for fast charging. No matter where we walk in the streets, we can see people looking down at their mobile phones with their heads down. Eating, shopping and dating can't stop people's desire to play mobile phones. Nowadays, even for a newborn child, parents who put their mobile phones next to their children in order not to cry or when their children cry are leaders. This can also be said to be an addiction to mobile phones.

I think no matter how powerful the endurance of smart phones is, we can't stand reading novels, watching dramas and playing games all the time. The machine will rust if it is not used for a long time, but it will be counterproductive if it runs for a long time. The same is true for mobile phones. Use it when you have electricity, use it again, and continue to use it. When there is no electricity, use it while charging, and use it when it is full. If this cycle continues, can the battery life of the mobile phone be maintained well?

In fact, it is not that the endurance of mobile phones has decreased, but that people's demand for mobile phone power is getting higher and higher, and their expectations are too high. No matter how good their ability is, they can't feel the good of mobile phones. Think about it, what if we can spare a little more mobile phones and let them do this? Fake mule? Take a rest, maybe the money we spend on mobile phones will be greatly reduced every year, which will give us greater ability to bear other expenses and let us see a better life outside of mobile phones.
