Motorola's page for the razr 2025 opens with reassurance: it says it is normal for a phone to feel warm or even hot depending on how you use it, and that a hot phone will slow charging, reduce brightness and limit other functions until it cools, or shut off. It lists the causes: graphics-intensive gaming in high performance mode, GPS navigation, tethering or a Wi-Fi hotspot, fast charging with a high-wattage or wireless charger, large downloads and uploads such as initial setup or restore, long camera use, and weak signal.
Pause those, use the charger that came with the phone, keep the phone out of heat and out of soft bedding, and lower brightness. If it is hot while idle, turn it off and on, which stops a stuck background process.
Differential
Likely causes of “motorola razr+ and razr (2025) gets hot or shows a temperature warning”, and how to tell them apart
- 1
Initial setup, restore or many app updates
What separates it Warm for days on a new or freshly restored phone
How to confirm Motorola lists downloading and restoring data among the causes; wait for it to finish
- 2
Gaming or navigation in a folded pocket
What separates it Warm at the hinge area during maps or games
How to confirm Pause the app; Motorola names gaming and GPS
- 3
Fast charging with a high-wattage charger
What separates it It is warm while plugged in because of fast charging with a high wattage charger
How to confirm Motorola says TurboPower heat is normal; the rate slows at 111 degrees F
- 4
Hotspot or tethering
What separates it The phone is warm whenever the hotspot is switched on and other devices are connected
How to confirm Turn the hotspot off when not in use
- 5
Weak signal
What separates it The phone is warm and drains quickly in a room with a poor mobile signal
How to confirm Motorola lists weak signals for an extended period as a cause; move or use Wi-Fi
- 6
A stuck process
What separates it The phone is hot even when it has been idle with the screen off
How to confirm Turn the phone off and on, as Motorola says
Before you touch a setting
Record this first — changing settings destroys the evidence
- razr+ or razr, and whether it was open or closed
- What was running, and whether it was charging
- Whether it dimmed, slowed or shut off
- Whether it was in the sun or on a soft surface
Try in this order
0 of 7 completedPause heavy apps
ReversiblePause heavy apps, by closing games, navigation and camera use until the phone cools, and then test again to see whether it helped.
Unplug and cool it
ReversibleSlow charging and screen dimming are Motorola's safeguards against heat, so let the phone cool down and it will recover by itself.
Keep it out of heat and soft bedding
ReversibleDo not charge on a pillow or blanket, because soft surfaces trap heat and can make the phone throttle or become a fire risk.
Use the supplied charger
ReversibleAvoid high-wattage third-party chargers that are not designed for the phone, since they can overheat it and shorten the battery's life.
Lower brightness
ReversibleThe razr+ panel runs up to 165 Hz per GSMArena, so try a lower refresh rate too.
Restart
ReversibleTurn the phone off and on again to stop a stuck process that may be keeping it busy and hot when idle.
Book service
ReversibleIf it stays hot when idle after a restart, contact Motorola so the phone can be checked for a battery or software fault.
Model-specific
What is true of this model and not of its siblings
- Chips
- razr+ (2025): Snapdragon 8s Gen 3; razr (2025): an octa-core Cortex-A78/A55 chip, per GSMArena.
- Charging heat
- Motorola says TurboPower rapid charging can heat the battery, and the rate slows if it reaches 111 degrees F.
- Part numbers
- No part number is needed. The XT model number is under Settings, About phone.
- Tools and supplies
- A hard, flat surface to charge on, a dry towel and a flashlight. Do not use ice, a freezer or a hair dryer.
- Repair cost
- MotoCare deductibles run $5 to $99 (Extended) and $26 to $99 (Accident Protection), per Motorola. Out-of-warranty quotes appear when you submit a repair.
Stop boundary
When this stops being a self-service repair
- !If it is hot while idle after a restart, contact Motorola Support
- !If it shuts down repeatedly from heat, book service
- !If it swells or the fold gapes, stop charging and get it inspected

Exact questions
Common questions
Does the phone warn me before it shuts down?+
Motorola says a hot phone slows charging, reduces brightness and limits other functions until it cools, and shuts off automatically only if it gets too hot. Those earlier signs are the cue to pause the game or navigation and let it rest.
Should I keep the phone closed or open to cool it?+
Motorola's articles give no rule for the fold. Its advice is to pause resource-intensive features, keep the phone away from heat sources and off soft bedding, and let the phone rest somewhere ventilated, so open it on a table if it is warm.
Is it normal for a razr to get hot?+
Motorola says it is normal for the phone to feel warm or even hot depending on how you use it, and it protects itself by slowing charging, reducing brightness and finally shutting off.
Does the razr+ run hotter than the razr?+
GSMArena lists a Snapdragon 8s Gen 3 in the razr+ against a lower-tier octa-core chip in the razr, so heavy loads will differ.
Can wireless charging cause heat?+
Yes. Motorola's charge page says the phone may heat up more with wireless charging than with USB, and thick or magnetic cases interfere.
Does closing the phone trap heat?+
Avoid using GPS or gaming while the phone is folded in a pocket.
What if it is hot but I am not using it?+
Motorola says a process can get stuck; turn it off and on.
Should I use the charger that came with it?+
Motorola says so, as high-wattage and non-matching chargers add heat.
Is a warm hinge a fault?+
Not by itself. Motorola's care page lists hinge sounds and slight waviness as normal, and heat as a load matter.
Will Battery Saver cool it?+
It reduces background activity and so load. Motorola lists lowering brightness and pausing apps as the fixes.
Does the weak signal matter?+
Motorola lists using the phone in weak signal for an extended period as a heat cause.
When should I book service?+
If it stays hot when idle after a restart, or shuts down repeatedly from heat.
Does a case help?+
Motorola says to keep the phone away from heat sources and poorly ventilated spaces; a thick case adds to that.
Is heat covered by warranty?+
A hardware fault is under the one-year warranty; liquid and physical damage are not.
Should I reset the phone?+
Only after the steps above, with a backup.
