Me personally - I usually have 4-5. Then I settle into 1-2 that I like. In the past I’ve had 6-9. This last phone I really tried to reduce that. Same - I do 1-2 year phones.I am curious how many cases do you guys own for your phones? I always feel bad getting more than 2-3 cases if I don’t plan to keep the phone more than 1-2 years.
