And what is most important is to connect the device to mobile data (not WiFi) and tune the brightness all the way up while checking out the phone and running a few apps. A decent battery should last 25-40 minutes of screen-on time per 10% of the battery.
2) The RAM and ROM of the phone.
Many people confuse these two things. The RAM of a phone is different from the ROM. The RAM of a phone varies from 1 GB to 8 GB..
A 1GB RAM phone cannot run apps that a 2GB RAM phone can. It is advisable to go for a phone whose RAM is higher than 1 GB..

3). Bottom and Ear Speakers
Another One of the most important things to check while buying a used phone is this: It is advisable to make a phone call while checking the phone to see if the speakers are faulty.
4). Screen Calibration
Check the screen calibration of the phone to see if it works, text the keyboards, and drag an app to the home screen. If the app continually escapes your touch, it means the screen calibration may be faulty.
5. Screen protector:
Don't buy a second-hand or used phone with a screen protector on it. Remove the screen protector to check if the screen is okay.
6) Camera
Check the front and back cameras to see if the camera is blurry.
7). Overheating
If you are buying a used phone in direct sunlight, there may be a case of overheating. If the phone becomes hotter than normal, it is advisable not to buy it.

If a phone cannot be factory reset, the person may be using some apps. That's why you need to do a factory reset before paying for the phone.
