Precautions for mobile phone accessories
During the charging process of the mobile phone battery, it should be noted that the output voltage of the power supply must be within the specified range, otherwise the charging function cannot be realized.
When using the data cable, pay attention that the transfer connector must be matched, otherwise the corresponding use function will not be realized.
The related mobile phone accessories must be placed in a dry environment. Rain, moisture and various liquids or moisture can corrode electronic components and devices.
When purchasing mobile phone accessories, it is best to go to a franchise store (cabinet) authorized by the manufacturer to purchase, so as to ensure the purchase of original accessories of authentic quality, so that the mobile phone can be used safely and normally. Because of the random selection, the mobile phone may not reach the optimal state of use, and even affect its normal use in severe cases. Secondly, it may cause damage to the mobile phone or battery and shorten its service life.
When buying a mobile phone film, in addition to looking at its material, it is also necessary to understand the wear resistance, light transmittance and stickiness of the film. Professional mobile phone film people said that the transmittance of the protective film is the most important factor.
Wear resistance: The mobile phone film is used to protect the screen, so its own wear resistance must be high. Especially for some mobile phones with handwriting input, the wear resistance of the film is even more important. Generally speaking, the higher the abrasion resistance of the mobile phone film, the higher the smoothness.
Light transmittance: The mobile phone film with poor light transmittance will hurt the eyes. Under normal circumstances, the light intensity of the mobile phone screen itself is already very low. Putting a layer of film will increase the fatigue of the eyes. The transmittance of high-quality mobile phone film is about 95%, while the low-quality film is below 80%.
Easy to stick: High-quality film can be automatically pasted without bubbles on the premise of ensuring that the screen surface is clean. More importantly, high-quality stickers are mostly electrostatically pasted, no need to apply glue, and can be used repeatedly or even washed. In general, the inferior film has glue on the back, which can never be used repeatedly, not to mention washing.
