If your OnePlus 15 gets unusually hot while charging, it can feel alarming. Heat during charging is not normal when it becomes excessive, especially if the phone slows down or stops charging altogether. This issue is often linked to charging habits, accessories, or background activity, and you can usually fix it without professional repair.
Why Your OnePlus 15 Overheats During Charging
- You are using a fast charger or cable that is not optimized for the device.
- Background apps are running heavily while the phone is plugged in.
- The phone is charging in a warm or poorly ventilated environment.
- Battery optimization features are disabled or not working properly.
- The charging port or cable is damaged or dirty.
1. Stop Using the Phone While Charging
Using your phone while it is charging forces the processor and battery to work at the same time. This creates extra heat, especially during gaming, video streaming, or video calls.
Letting the phone rest during charging helps it cool down and charge more efficiently. It also reduces long term battery stress.
Plug in your charger, and then lock the screen.
Set the phone aside on a flat surface, and then avoid using it until charging finishes.
2. Check the Charger and Cable
Not all chargers deliver power safely, even if they physically fit. Low quality or incompatible chargers can cause unstable power flow, which leads to heat buildup.
Using the original charger or a certified alternative ensures proper voltage and temperature control. This is especially important for fast charging.
Unplug the charger, and then inspect the cable for bends or damage.
Switch to the original OnePlus charger, and then plug it back in.
3. Charge in a Cooler Environment
Heat builds up faster when charging in warm rooms, on beds, or under pillows. Poor airflow traps heat and prevents the phone from cooling naturally.
A cooler surface allows heat to dissipate more effectively. This can make a noticeable difference during charging.
Move the phone to a hard, flat surface, and then remove any case.
Charge the phone in a well ventilated area, and then keep it away from direct sunlight.
4. Close Background Apps Before Charging
Apps running in the background can keep the processor active while charging. This combination often causes the device to warm up faster than usual.
Closing unused apps reduces system load and helps control internal temperature.
Open Recent apps, and then swipe away all running apps.
Plug in the charger, and then let the phone charge with the screen off.
5. Inspect and Clean the Charging Port
Dust or debris inside the charging port can interfere with proper power delivery. This can cause resistance, which leads to excess heat during charging.
A clean connection helps maintain stable charging and keeps temperatures lower.
Turn off the phone, and then unplug the charger.
Use a dry soft brush, and then gently clean the charging port.
Overheating during charging on the OnePlus 15 is usually caused by external factors rather than a hardware defect. Once you adjust how and where you charge, the phone should stay cooler and charge more safely.
FAQs
Is it normal for the OnePlus 15 to feel warm while charging?
Yes, mild warmth is normal. Excessive heat, especially with slow charging or warnings, is not normal and should be addressed.
Can fast charging damage my battery if the phone overheats?
Fast charging is safe when conditions are ideal. Repeated overheating can reduce battery lifespan over time.
Should I stop charging if the phone becomes very hot?
Yes. Unplug the charger, let the phone cool down, and resume charging only when the temperature returns to normal.
