Do NOT buy refurbished

If it’s not from Apple don’t get it. I bought a refurbished iPad mini 6 from backmarket in excellent condition. Everything looks perfect it looked like it has NEVER been used. There was not 1 ding on it or scratch. After setting it up and updating the battery was drained a little bit. I overlooked it because it just got done updating and downloading apps. After having it for 2 days I realized the battery was dropping way too fast. If I watched a 10min YT vid it would drop at least 5-7% this can’t be right. I decided to buy a new iPad mini 7 to test the battery and the new one has lasted miles longer than the refurbished. The battery on the refurbished was absolutely horrible. I could not even get 3 hours out of it. Don’t cheap out to save $200 use the apple student discount and get the iPad mini 7 for $450 (if you are a student) it is going to have much better longevity than a refurbished that could have been sitting for years draining the battery. Just my thought on it.
