Motorola Moto Z4 User Manual

Phone feels warm or hot
Overview
It's normal for your phone to feel warm, or even hot, depending on how you're using it.
If your phone ever becomes too hot, it will ask you to turn it off so it can cool down. Some phones will stay
on but limit the phone's capabilities until it cools down.
If your phone is too hot to touch, use a different phone, tablet, or computer to contact Motorola support.
Reasons your phone may get warm
Doing one or more of the following activities may cause your phone to get warm:
•
Playing videos, games, or other media apps
•
Using GPS navigation
•
Tethering your phone or using it as a Wi-Fi hotspot
•
Using phone while it's charging
•
Downloading or uploading a lot of data
Ways to keep your phone from heating up
•
Pause resource-intensive features or apps until your phone cools down.
•
Use the charger that came with your phone, or a charger that is compatible with your phone.
•
Keep your phone away from direct heat or excessive sunlight.
•
Don't keep your phone in enclosed or poorly ventilated areas where heat can easily build up.
•
Lower your phone's display brightness.
If you're not using or charging it
Sometimes a process can get stuck in the background. If your phone is hot but you're not using or charging
it, turn your phone off and on again. This will stop the previously stuck process and resolve the issue.
