Some precautions for mobile phone accessories

During the charging process of mobile phone battery, pay attention to 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 to that the middle adapter must match, otherwise the corresponding use function will not be realized.
Relevant mobile phone accessories must be placed in a dry environment. Rain, moisture and various liquids or moisture will corrode electronic components and devices.
When purchasing mobile phone accessories, it is better to buy them at the exclusive store (counter) authorized by the manufacturer, so as to ensure the purchase of authentic original accessories, so that the mobile phone can be used safely and normally. Because of random selection, the mobile phone may not reach the best use state, and even affect its normal use. Secondly, it may cause damage to the mobile phone or battery and shorten its service life.
In addition to its material, you should also know the abrasion resistance, light transmittance and viscosity of the film when purchasing the mobile phone film. Professional mobile phone film stickers said that the transmittance of the protective film was the most important factor.
Abrasion resistance: mobile phone film is used to protect the screen, so its abrasion resistance must be high. Especially for some hand-written mobile phones, the wearability of the film is more important. In general, the higher the abrasion resistance, the higher the smoothness.
Light transmittance: The film with poor light transmittance will harm the eyes. Under normal circumstances, the illumination of the mobile phone screen itself is already very low. Applying a layer of film will increase the fatigue of the eyes. The light transmittance of high-quality mobile phone film is about 95%, while that of inferior mobile phone film is below 80%.
Easy adhesion: high-quality film can be automatically pasted without bubbles on the premise of ensuring the cleanness of the screen surface. More importantly, the high-quality film is mostly pasted by static electricity, which can be used repeatedly or even washed without glue. Generally, there is glue on the back of inferior film, which can never be used repeatedly, let alone washed.
