How to know iPhone is Original (retail) model or refurbished

  1. Go to Settings > General > About.
  2. Scroll down to the Model section. You'll see a collection of numbers and letters to the right of the Model designation, but the important part is the first letter:
If the first letter is M, your phone is retail unit.
If the first letter is N, your phone is replacement unit.
If the first letter is P, your phone is personalized (engraved) unit.
If the first letter is F, your phone is refurbished unit.


You may go to Apple's Check Coverage website. You can type your iPhone's serial number into this site to see whether or not it has been activated before.
If the phone you're buying has been activated, that doesn't necessarily mean it's refurbished;
however, this process will weed out people attempting to sell a phone as New when it's actually used.


Type your phone's serial number and verification code, then click Continue.

Doing so will take you to your iPhone's diagnostics page, where you'll see something like This phone has not been activated if the phone is new.

Weigh scale on iPhone using Touchscale

Touchscale is website that allow you to weigh things on your iPhone. It use your 3D Touch Device as a scale. The iPhone weighing function can only be used on models that support 3D Touch. From iPhone 6s/6s Plus until the latest model. As for the iOS version, there is no limit.


How to setup iPhone for weigh scale

First go to iOS Settings > Accessibility > Touch. Select 3D and touch feedback touch, and turn on 3D touch. Open the TouchScale webpage directly through the iPhone browser, and you can place items on the iPhone to measure the weight.


Things to consider

Please pay extra attention not to put metal or heavy items to avoid cracking or leaving the screen scratches. Also, whatever you’re weighing need to be conductive to activate the touchscreen sensor. For example you can’t weigh a plastic bottle because the phone doesn’t recognize there is anything touching the screen. So you need something like a spoon on the screen to trigger the iPhone and place the plastic bottle on top of the spoon. To weigh the plastic bottle, simply deduct the spoon weight.


Last but not least, compare it with an electronic scale, you will find that it’s not so accurate, so just play and entertain.
