The most common reasons, from most to least likely:
Quick fixes: take off a thick case while fast charging, charge away from direct sun, and give it a week before you judge battery life.

Apple’s own magnetic charger. Pair it with a 30W or higher USB-C adapter for its fastest wireless speed. The 2 m cable reaches from wall to pillow.
Charges your iPhone (15W Qi2), Apple Watch and AirPods together. Buyers call out the strong magnets and compact footprint.
Small enough for a pocket, and it has enough power for your MagSafe charger, a MacBook Air or fast wired iPhone charging.
The woven cable resists fraying, it’s long enough to use the phone while charging, and 240W means it will never limit a charger.

| Power bank | Capacity | Best for | Price |
|---|---|---|---|
| TORRAS MiniMag | 10,000mAh, magnetic | Everyday carry, no cables | $49.99 |

Our pick: the Anker 737 if you travel, and the TORRAS MiniMag if you just want to get through a long day. It’s ultra-slim and snaps onto the back.
Warm during setup, fast charging or gaming is normal. If it's too hot to hold while idle, restart it and contact Apple.
No, but heat does. Charge in a cool spot and use the charge limit setting.
No. It comes with a USB-C cable only, so add a USB-C adapter.
