A 2025 Motorola razr that feels hot has a thin folding body that holds heat, a small battery with large demands and a cover screen that sits next to the processor, so heat is a trade-off of the design more than a fault. Start by working out when it gets hot. Charging, gaming, navigation, video recording and mobile hotspot all push it, and doing them together in a warm place, in the sun or in a closed case makes it worse.
The checks in more detail
If the phone warms during charging, charge it open and away from sun, take it out of a thick case and use the charger that came with it; fast charging adds heat, and a second device, such as a car mount that blocks the back, worsens it. Do not charge with the phone folded in a pocket or a bag. If the heat happens at idle, something is using the processor. Open Settings, Battery, Battery usage and look for an app using a lot, and for a recent app update that has gone wrong.
Restart the phone and update the software, since Motorola releases fixes for thermal behavior and for runaway apps. Check Settings, Battery for Adaptive battery and battery saver, and use the saver in warm conditions. Lower the screen brightness and the refresh rate, which are the largest controllable heat sources, and close apps that you are not using. A phone that was just set up runs warm while it restores apps, so wait a day. For the fold, keep it clean of dust and lint, since debris can make the hinge area warm, and avoid pressing on the inner screen.
If the phone shuts down for heat, let it cool before using it. A phone that is hot with nothing running, a battery that swells or a casing that bulges needs attention, and you should stop using it and contact Motorola. Remember that Motorola's cover screen apps run on the same processor, so a long game on the cover screen heats it too. Use airplane mode if you need to rest the radios while it cools. Keep the phone out of hot cars.
