1. Display - LCD vs Amoled 

You probably must have heard about these two types of displays. But you really know what are the major difference between them?

Firstly let's talk about LCD Displays

LCD stands for Liquid Crystal Display.

• It's a type of flat panel display which uses liquid crystals in its the primary form of operation.

• In LCD display panels, it uses a single light source and reflects it all over the display
• They have a thick panel on display
• the color accuracy and contrast is low because only one light source is present
• In IPS LCD displays in-display Fingerprint Sensor cant be used
• they have a high display life span (4-6 years because no organic material is used.

Secondly, AMOLED Displays

AMOLED Stand for Active-Matrix Organic Light-Emitting Diode

• In AMOLED display panels, it uses multiple light sources as pixels, which is spread all over the display in a systematic way
• They have a thin panel on display
• the color accuracy and contrast is high because of multiple light sources 
• In AMOLED displays in-display Fingerprint Sensor can be used
• they have a low display life span (3-4 years) because organic material is used as a layer.

2. Processor- Mediatek vs Snapdragon

In today's world processor plays a major role, it's is the core of every smartphone, There are two major processor chip manufacturing companies for smartphones - Mediatek and Snapdragon.

Both companies are in a race to capture the whole chip industry.

the most recommended processors according to price tags of Smartphones are shown below:

Below 50000- Snapdragon 865 or Mediatek dimensity 1200

Above 50000- Snapdragon 888

3. Ram - 6,8 GB

RAM stands for Random Access Memory.  RAM is basically temporary storage that stores the memory of apps you have opened since you have turned on your smartphone.

The more RAM your phone has, the more quick and fast your apps load and access.

The recommended RAMs are 6GB, 8GB RAM for daily usage.

4. Internal storage- 64, 128GB

As the name suggests Internal Storage is the storage placed inside the Smartphone and they store music, videos, files, and all app data.

The recommended Internal storages are 128GB and 256GB for daily usage.

5. Camera: Megapixels

The camera plays a major role in users of today's generation almost everyone takes pictures of all the good things that happened to them and stores it as a memory of their life and nowadays Smartphone cameras are coming closer to high DSLR camera quality. Better the Megapixel count, the more quality the picture will be.

Now `the highest Megapixel available to a Smartphone is 108MP

The recommended Camera sensors are 64MP IMX682  and 50MP IMX766 or 108MP  for daily usage.

6. Battery and charging

In the busy schedule, we often didn't get time to charge our Smartphones. batter capacity should be more for those busy people with fast charging technology.

Nowadays usually 4500mAh or 5000mAh  with 30Watt or 65 Watt Fast Charging is recommended ideal or else Bigger the battery storage heavier your smartphone will be.

The recommended Battery capacity is 4500mAh with 30Watt fast charging or 5000mAh with 65Watt fast Charging for daily usage.

7. IP rating: IP65, IP55

I have already written a full article about IP ratings .

In short, IP rating is Waterproofing Standard given to electronic items. and this is not usually given in mid-ranger smartphones.

8. Security: fingerprint sensor, face unlock

On increasing privacy security almost every smartphone has a fingerprint sensors and face unlock options.

• In the budget category, a Smartphone fingerprint sensor is given at the Back of the smartphone
• In Midrange Smartphone they are given inside Power button which doubles up as fingerprint sensors
• In Flagship highEnd or Mid flagship smartphones, they provide In-Display Fingerprint sensors.

9. Speaker: Stereo speaker, Mono speakers

Speakers will play a major role if you are a Gamer or watches many movies on Smartphones.  most of the Smartphones are provided with mono speakers or down-firing Speakers, In which sound volume will be low and no surround experience.

In Good priced Smartphones they Provide Stereo Speaker i.e there will be two speaker one on the top as front-firing and one in the bottom as down-firing. This helps in experiencing surround sound quality.

10. Refresh Rate: 60Hz, 90Hz, 120Hz

If you are Pro Gamer they surely you will be aware of this term. It's basically, the standard is given to display about which how many times smartphone display refreshes itself per second.

The standard refresh rate in Smartphone is 60Hz.

In mid-ranger smartphones, 90Hz display is given, and in high-end smartphones, 120Hz is given.

In short,

The more the refresh rates, the more smooth the screen will glide through your fingers.
