Higher screen resolution on smartphones means sharper images
In the race among smartphone manufacturers, we've seen smartphones with super high-resolution screens. From HD, FullHD, then 2K QuadHD on the LG G3 or 4K on the Sony Xperia Z5 Premium. Super high resolutions have even been applied to high-end TVs.
Some people believe that the higher the screen resolution on a smartphone, the sharper the images because we always look at the phone up close. But the truth is, this is only partially true. Only smartphones with resolutions below HD in the past might show pixelation or image distortion during normal use, as the pixel density is small, still within the eye's limit.
With standard Retina displays from Apple and FullHD, 2K, or 4K screens on Android phones, people cannot perceive any difference. This means that increasing the resolution does not make images appear sharper. The most noticeable differences between types of screens, as well as the characteristics of manufacturers, lie in color, contrast, black representation, and screen brightness.
More camera megapixels mean better photos
This belief has been proven entirely wrong. The number of pixels in a camera determines the size of the captured image; a larger image size does not equate to a beautiful image. Moreover, having a 23 Megapixel camera on a phone does not guarantee beautiful photos. Photo quality depends on many factors, including sensor size. Larger sensors usually have larger pixel sizes, capture more light, a crucial part of photography.
Charging overnight will ruin the battery
Some people use their phones all day and charge them before going to bed, unplugging them in the morning. Some believe that doing so will degrade the battery and may even cause damage. Most smartphones nowadays use lithium-ion batteries, which can stop receiving current when fully charged. This means your phone will stop charging once it's full, even if you leave it plugged in all night. However, whether this habit damages the phone's battery is still uncertain because there hasn't been any official research to prove it.
You must fully drain the phone battery before charging
Smartphone batteries 'remember' a charging cycle when we use up 100% of the battery. However, it's unnecessary to completely drain the battery before recharging it to 100%, and doing so regularly may even be harmful as it can deactivate some battery cells. You can use and recharge your phone whenever necessary. Experts often recommend letting the battery drain fully and recharge once a month as the optimal practice.
