I have just bought an iPhone 13 renewed and I did ask for a brand new battery upgrade.

On IOS it shows 100% but I did check with coconut battery software on macos and that's what I have (see pic)

Do they have replaced the battery or just reprogram the parts that talks with IOS?

Based on the output from your Coconut app it does not look like a battery was replaced with a "New" battery. Even if it shows 100% in iOS. What does the Battery status show under settings on the iPhone 13 Mini?

The standard Apple battery specs are Li-Ion 2438 mAh (9.34 Wh). Do you have another iPhone to compare the results of the Coconut app?

It's a 13 not a mini. Standard 13 should have 3240mAh. On my settings it only says 100%, no more info I'm afraid.
That's what I thought, the chip was reprogrammed to 100% and battery wasn't replaced, glad I'm in the 30 days and I will then return it.

Is there anything else I should check to spot if battery has/hasn't been replaced?
 
All newly-installed smart batteries should be calibrated as soon as possible. This helps your system get an accurate reading on the battery’s state of charge. Without calibration, the battery percentage reading will be incorrect, and your device may behave oddly—shutting down suddenly even though the new battery “reads” half charged, or working for hours when the battery reads nearly dead.

For phones, tablets and smartwatches:

  1. Charge it to 100% and keep charging it for at least 2 more hours.
  2. Use your device until it shuts off due to low battery.
  3. Charge it uninterrupted to 100%.

By the way, it’s also good practice to recalibrate every few months or so. And, no, it doesn’t harm the battery as some falsely claim. I have proof and continue to gather data.
