Well, there are plenty of smartphones in every category when you go to buy one. Most of the time, you cannot decide which one to pick as almost every other smartphone looks perfect with ongoing upgrades, it becomes quite a difficult task how to purchase a perfect smartphone for yourself.
What all to consider before buying a smartphone?
Battery
When it comes to bigger battery backup don't just look for a bigger mAh battery, try to see better software that is more smart and compatible with the battery so that the software has the ability to close most of the apps in the background and thus can lead to good battery backup. Although the battery with fast charging also gets drained easily as compared to normal charging, depending on what you require, try to get batteries in the range of 4000-5000mAh as they work best.
Software
Well, every brand claims to have the best software/processor. For this, I just suggest you buy a brand as per your need as some are performance-centric gaming smartphones whereas others tend to work on customization and camera quality. Make a decision and check these factors before purchasing your smartphone.
Display
The two types of display which you need to consider that your smartphone must have and that is either it should be LCD with no less than a refresh rate of 120Hz or AMOLED with no less than a refresh rate of 90Hz.
Storage
Further, your storage should be UFC3.0 type and not e.MMC type as the latter is generally slower than the first one, which will make your smartphone slow no matter how bigger your storage is.
Connectivity
Also, when we talk about 5G, for now, its a gimmick I believe because you need 10- 12 bands of support for 5G which is generally not available in present smartphones so even if you are buying one try to look for a phone with at least more than 6 bands support for 5G
Camera:
Last but not least, try to look for a camera that clicks decent pictures both in daylight and nighttime irrespective of how Megapixel it has and that you can analyze by reviewing the pictures clicked from it.
Moreover, your phone should be 3.0 USB and OTG compatible for fast and smooth data transfer, stereo speakers should be installed for loud music and e sim. These few things one can look up to before buying a smartphone and could get the maximum benefit of your purchase.
