For smartphones with a battery capacity of about 4000mAh or more, using only 5V normal charging technology, you must wait more than 3 hours to charge the battery.

For those of you who only use one phone, having to wait for more than 3 hours to charge is too inconvenient, isn't it.

Of course you could say I can charge and use, but actually charging and using is a very dangerous habit that you should abandon.

When buying a phone you should also consider whether the phone is equipped with fast charging technology or not, do not pay too much attention to the battery capacity but forget about fast charging technology.

#2. OTG connection

When buying a smartphone you should also pay attention to OTG connectivity, with smartphones under 5 million currently have brands that do not support OTG connection, so when choosing the phones in this price range, you should learn carefully See if it supports this technology.

# 3. Internal memory is high capacity

All smartphones are equipped with internal memory for storing images, videos … But depending on the price, each smartphone has its own storage limit.

When buying, you should consider carefully choosing the amount of internal memory. As the camera is getting more and more advanced in quality, it means that the size of photos and videos has increased tremendously.

If the internal memory is small then your phone will not have enough space for a short time. So you should pay attention to this issue a little. And note whether the smartphone supports the memory card slot or not, if any, it will be more secure.

Because when almost out of storage capacity, the phone will appear a warning of running out of space, it constantly alerts => this is annoying and frustrating for the user, then you need to choose between deleting Take those apps or photos and mine.

The storage capacity of internal memory on current phones is 8GB, 16GB, 32GB, 64GB, 128GB, 256GB and 1T. For the same price range, if you have a high capacity model, you should choose one that will help you store more.

# 4. Anti-vibration technology

The use of phones to record videos and take photos is a regular practice in modern society today.

With a smartphone equipped with anti-shake technology will help make your photos and videos more beautiful and professional.

Videos taken from smartphones with a camera equipped with anti-shake technology will keep that video from jumping in steps, and the image will not be blurred when shaking hands.

Vibration reduction technology currently has two common types of anti-vibration Digital and anti-vibration optics. Optical stabilization is more highly rated than digital stabilization.

Anti-shake technology on the camera has gradually been brought down to mid-range products such as the Galaxy A51. It is hoped that in the future, anti-vibration technology will be applied on all cheap smartphones.

This technology has been available for a long time but has not been popular due to its expensive and complex technology, which requires a higher assembly process and is more expensive.

Currently this technology has not been applied to mid-range products, it is only applied to high-end products such as iPhone, Samsung Galaxy S, Galaxy Note and a few other flagships of other brands.

IP68 water resistance standards are commonly applied today.
