He is bad update phone? Is my phone resistant to rain? The battery does it charge once it is completely consumed? Steffen Herget of the German trade magazine “c’t” explains which stories are true, which belong to the realm of legends and which tips are really useful.
1: It is better not to install updates as they only slow down the functioning of the device.
It’s not true. cell phone users should install updates regularly, advises Steffen Herget. These not only bring new features, but also close security gaps. Although older devices are rarely overwhelmed with new features and slow down, updates are a must for security reasons.
2: All smartphones are rain resistant
It depends on the amount of moisture. A few drops usually don’t harm devices, Herget says. But if a cell phone falls in the water, can be damaged despite the IP protection standard. This protects the device against water and dust, which may cause failure or damage to electronic components. In addition, continues the expert, water can more easily penetrate through openings, for example for headphones or charging cables.
3: In mobile cameras, high resolution indicates good photographic quality.
It’s not true. On modern devices, the quality of photos does not depend on the resolution, but on the quality of lenses, sensors and other components technicians, explains Herget. Additionally, camera software is becoming increasingly important to image quality, especially when shooting at night or in low light conditions.
4: You should always let the battery fully discharge before connecting the phone to the charger.
It’s not true. The idea dates back to when nickel-cadmium batteries were prevalent. Today’s lithium-ion batteries can and should be charged when not discharged. Steffen Herget recommends never going below 20% battery capacity. Indeed, a complete discharge damages the battery.
5: In flights, you must turn on airplane mode, otherwise the plane may crash.
It’s not true. In airplanes, passengers are asked to turn off their mobile phones or activate airplane mode. But not because the devices connected to the signal can bring down the plane, but because could interfere with radio traffic. Otherwise, security measures would also be much stricter, Herget points out.
6: Using the mobile outside during a storm attracts lightning.
It’s not true. smartphones have very little metal to attract lightning, Herget explains.
7: Phones that don’t reboot regularly become slower.
It’s not true. Unlike computers, Herget explains, cell phone owners they don’t have to turn off their devices regularly. Embedded operating systems are designed for continuous use.
8: Talking on the phone at the gas station is dangerous due to possible explosions.
It’s not true. Signs prohibiting the use of smartphones at gas stations do not warn of an impending explosion if someone is talking on a cellphone. Rather, they refer to increased risk of fire which usually exists in places with flammable vapors, and they want to prevent a damaged battery from igniting in the worst case and causing a fire, for example if a phone is accidentally dropped. For this reason, Steffen Herget advises users to keep their devices in their pockets when refueling to be safe.
9: Closing open apps when not in use will make your phone run faster and save battery.
It depends on the age of the device and your own usage behavior. Modern phones slow down the power consumption of apps on their own, Herget says. So, no need to close them. On the contrary, even the battery is saved if regularly used applications remain open and do not have to be restarted again and again. On older devices, it might be a good idea to close apps instead.
10: Text messages can infect the mobile with a virus.
It’s not true. According to Herget, viruses cannot be transmitted directly in this way. However, it is quite possible for hackers to use this route to send links to phishing sites or malware downloads.
