On Child Development center, This Is the Influence of Gadgets

The easiest way for today's parents to calm a fussy child is to give them gadgets. However, did you know that this habit is not actually recommended, you know.

According to data reported by the New York Times, 70 percent of parents admitted to allowing their child (age 6 months – 4 years old) to play mobile devices, when they were doing household chores. In addition, 65 percent do the same to calm your child when in a public place.

According to a psychologist professor from Temple University, USA, this phenomenon is really dangerous. The expert said that if children can not escape from this "digital candy", it can have a negative influence on their social development.

Influence The Child's Mental

According to a psychology professor from Iowa State University, playing video games can increase the likelihood of depression in a child. He conducted research to find out about the relationship between video games and cases of depression in children and adolescents. According to him, when the child has a problem, the easiest escape by playing video games. So, what's the impact?

Unwittingly, it will lead to dependency and cause them to become increasingly isolated from social life. As a result, they will be prone to depression when "forced" to deal with the real world. Not only that, when researched further, the influence of gadgets on children also makes their learning values tend not to be good.

The reason is simple, children often prioritize playing gadgets compared to learning. Therefore, parents should always supervise the use of gadgets in children. For example, limit the duration of use to two hours a day for children, or a maximum of three hours for those in their teens.

Disrupted Sleep Schedule and Quality

Gadgets and electronic gadgets that are in the children's room, may have a negative influence on the rest time. For example, viewing social media, watching videos, playing games, or chatting for hours, doesn't rarely make them sleep late. According to experts, parents should not put TVs and computers in the child's bedroom. Not only that, try asking them to turn off their phones at bedtime. Because, playing mobile phone before bedtime can also decrease the quality of sleep.

According to a study, 75 percent of children aged 9-10 who use gadgets in the bedroom, experience sleep disorders that have an impact on their decreased learning achievement.

The Reality Is Inversely Proportional

It is no secret, now many parents who give their children a variety of gadgets for daily needs. Well, do you know how the children's lives of the bosses of giant gadget companies like Microsoft and Apple? Maybe you imagine that the boys are always surrounded by sophisticated devices. Well, the irony is that Bill Gates and the late Steve Jobs kept their children away from the device.

Microsoft's big boss didn't let his three children own their own phones before they turned 14. Despite his children's protests, Gates remained on his stance. Then, when his son had a cell phone, Gates kept his usage strictly set. The reason, the billionaire does not want his children's lives disturbed by the presence of various kinds of sophisticated gadgets.

As for Jobs, it's another story. She doesn't allow her children to use iPad tablets. He also banned his children from bringing gadgets to the dinner table during dinner with the family. As a result, her children are not dependent and addicted to gadgets.

4 Tips How to Fix an Overheated Smartphone

4 Tips How to Fix an Overheated Smartphone - The smartphones we use are basically an added complement to our lives. But as we increasingly rely on smartphones, we may feel helpless when traveling without carrying the device.

Similarly, during ramadan, we often rely on the camera on the smartphone to record sahur moments, breaking the fast and fasting or playing games. As a result, smartphones often get hot due to their relentless use. To prevent this, you can follow these tips:

Rest your smartphone

Say goodbye for a while on your social media pages and let your smartphone you used to rest. Yes! This method can at least cool the smartphone, because the light on the screen does not turn on.

Store in the shade

Avoid putting your smartphone in direct sunlight, especially during very hot days. Smartphones are one of the electronic devices that are prone to weather and will turn off automatically once the internal temperature reaches a certain point.

Lower the screen brightness level

The higher the brightness level of the screen on the smartphone, the more battery power capacity is required. This will result in a large use of energy that causes heat in the body of your smartphone.

Close game apps

Opening mobile game apps usually drains more battery power in smartphones. If this activity is done for a long time, then it may cause the performance of the chipset installed in the smartphone to be heavy and can cause heat.

To prevent overheating or overheating on smartphones used to play games for a long time, OPPO presents an intelligent solution. With the Multi-Cooling System technology presented in OPPO Reno5 F, you don't have to worry about smartphones getting hot anymore.

This technology is able to increase heat dissipation efficiency by 30% due to long-term use of heavy applications. In addition, the technology is able to read and analyze data from the temperature sensor located on the inside, then use it to estimate the temperature of the back cover to 1.5 degrees Celsius.

OPPO Reno5 F also has a smart temperature controller that can balance it with the performance of the device based on its daily usage scenarios. The Multi-Cooling System feature has a considerable role to keep the temperature stable when the game is running for a long time.

Wireless Air Charging Technology The Future of Recharge battery

Wireless Air Charging Technology The Future of Recharge battery

After the success of superfast charging technology with its Super VOOC, OPPO made another breakthrough in terms of charging their phones with a technology called Wireless 'Air Charging

This technology allows your phone's battery to charge without being wired or attached to a special tray that stays in one place. Currently there is not much information about the technology used by OPPO in detail, but we will try to explain how this water charging works or working principle.

The technological breakthrough exhibited by OPPO at MWC Shanghai 2021 showed that Wireless Air Charging is already able to run, not the concept like a few years before.

Broadly speaking, this method basically uses the way it works just like wireless charging. It's just undergoing further development, to be completely wireless and free from the need to be induced directly with resources.

Simply put, this air charging uses an antenna array consisting of "beacon antennas" and "receiving antennas". Where the Beacon Antenna serves to transmit signals in the size of a "millimeter wave" tape to the receiving antenna or filler pole.

Just to remind this millimeter wave covers a frequency range of 30 to 300 GHz.

Well, a flare antenna that also consists of many of these antennas will have several tasks at once. First it will determine precisely where the phone has the receiving antenna, then the second task is to send a millimeter signal to the specific receiving antenna.

This signal is then received by the receiving antenna and then processed into the form of electrical energy through a certain component so that it is able to charge the phone battery without having to stay in one place.

Don't you think? The future of charging the battery of mobile phones and other devices will be increasingly sophisticated and not troublesome to users anymore. OPPO itself has embedded this feature into OPPO X 2021 phones that can already be tried by visitors mwc Shanghai 2021.

Oh yes still remember with OPPO X 2021? It's a phone that has a scrollable screen. So the phone screen can be like a regular phone and can be as wide as a tablet with just an easy mechanism. So can't wait, right?
