Yeah that tracks - Good call on heat and fit - most edge cracks come from polycarbonate shells getting brittle. If you’re gaming or fast-charging, avoid doing both with the case on, and try not to remove and reinstall the case often since that creates stress at the corners and cutouts. For your budget, look for a one-piece TPU or a hybrid with a soft TPU bumper and flexible corners; those handle thermal cycles and pocket flex far better than rigid snap-on backs.
