Modern styles and functions of mobile phones have also reached an unprecedented level. Consumers have more choices. However, although everyone is so familiar with mobile phones, there may not be many people who know some cold knowledge about mobile phones. Today I will talk about 11 things related to mobile phones. Cold knowledge, but many people may not know it!
1, charging less than 10% affects battery life
Virtually all smartphone batteries nowadays are lithium batteries. It is normal for a lithium battery to have a 40-80% charge level, whether it is in standby mode or charging. However, if power consumption is too low (less than 10%), and even turn off automatically. Charging in this state will greatly affect battery life of mobile phone, as it will over-discharge lithium battery, and chemical activity in battery will decrease. This Cold knowledge wants to know.
2, it is just as durable without a mobile phone screen protector
If it was a smartphone in past, you must attach a protective film for mobile phone. It can really protect against scratches, but now, thanks to continuous improvement of technology of major mobile phone manufacturers, mobile phone screen is enough It is strong and does not need a protective film The current protective film is more psychological comfort.
3, closing a background program does not save energy
This is also a delusion that many people often make mistakes. They think that clearing and closing background programs will save energy. However, professionals often consider this statement to be quite absurd, because when you exit an application and start using other programs , RAM of first application program will be reserved, so that frequently used programs will remain in background, you can save memory reading step, this multitasking algorithm helps to save energy, for this interesting cold knowledge there can be a lot Nobody knows.
4. Faster charging in flight mode
For us ordinary people, frequency of using a mobile phone's airplane mode should be very small. In fact, this feature is still very useful. For example, charging will be faster. When switching to this mode, mobile phone's signal will be interrupted, location tracking will also be stopped, so after disabling these functions, phone will consume less power and speed up charging process.
5. The mobile phone can be tracked after removing SIM card
From some films, when a person takes out a SIM card, ability to track him is cut off. In fact, this is completely wrong. While mobile phone is on, it will search for nearest base stations, and base station will be located. Mobile phones, unless battery is fastened, really "have nowhere to go."
6. The appearance of plastic mobile phone cases provides many advantages
At present, when many people buy a mobile phone, they are ready to choose appearance material: glass or metal. They think plastic case is a low end product, but it's not. Due to material, appearance of plastic case mobile phone The weight is relatively light, it will not be overheated or too cold in summer and winter, and it will not shield signal Compared with glass case mobile phone, it will be more drop resistant as well maintenance cost is also very low, so appearance of the plastic body mobile phone is still good.
7, overnight charging will not harm phone
It is increasingly being said that charging your phone overnight is risky and shortens its lifespan, but some experts argue that this is completely false, as modern smartphones are at high risk of overcharging. Good protection: after fully charged, charging process will automatically turn off. , so overnight charging will not harm phone, I would like to know!
8, higher pixel size does not necessarily mean photo will be sharper
Many manufacturers are now using high pixel count tricks to lure consumers in by tricking consumers into thinking that more pixels, sharper photos will be. Actually it is not. The lens and sensor of mobile phone cameras are definitely superior in image quality. They play a more important role. If lens is defective, picture will be of poor quality. If lens is defective but pixel count is high, image will be high resolution and low quality. Therefore, this is just a simple consideration of problem of pixels, which is actually somewhat one-sided.
9, 4G network consumes more power than 3G network
We all know that 4G network download speed is definitely faster than 3G network, but 4G network also consumes more power, of course 5G is same, so if you just want to save more power, you can set your phone's network to On 3G network, if you want to download something, you can switch to 4G network. Although it's a bit of a hassle, it's still very practical.
10, 8G RAM is impractical
Undoubtedly, RAM is of course very important, but is it really necessary, like today's 8G RAM? The answer is definitely no. According to most users, there is no difference in daily experience between 8GB RAM and 6GB RAM. Even when running some large-scale games, there is no obvious difference. It's not very practical. , but price of mobile phones is much more expensive, you still need to pay attention to this so as not to waste money.
11, hair dryer will easily explode when drying a mobile phone
Sometimes, due to carelessness, water accidentally gets on a mobile phone, so some people use a hair dryer to dry it. In fact, it is very dangerous, as mobile phone itself is very afraid of heat, and heat generated by enough hair dryer in a short time It will harm mobile phone. In severe cases, there will be a risk of explosion, so try not to do this if possible.
