iQOO Care：3. Check device settings:
(1) Check if the personal hotspot is turned on. If other devices are connected to the hotspot, it will consume more battery power.
(2) Turn off unused features such as Bluetooth, NFC, WiFi, and mobile data.
(3) Go to Settings > Lock Screen & Wallpaper/Home screen, lock screen and wallpaper > Always on Display > change Display mode to "Move the phone slightly to display."

4. Restart device:
Please restart your device before observing the changes in battery usage.

5. Check signal status:
Check whether the signal is good and stable. If the device is in a low signal area, it will frequently search for networks and consume more battery power.

iQOO CarereplyiQOO Care：Further, please follow the below-mentioned steps for the heating issue:

We would like to inform you that, the limited by the size of the fuselage, in some high-power consumption scenarios, such as long-time gaming, taking pictures and videos, watching online videos/live broadcasts, etc., it is common for the fuselage to heat up. When the high-power consumption application is stopped, the temperature will gradually decrease decline.

Reduce the power consumption of app running
Enter iManager>Utility tools> Phone Cooling to cool down the phone; go to Settings>Battery and turn on Battery Saver mode. The system will intelligently adjust the CPU frequency, screen brightness, and lock screen time reduce phone power consumption, thereby reducing power consumption and heat.

iQOO CarereplyiQOO Care：Note: Phone Cooling will clear all background apps. It is recommended not to use "Phone Cooling" during important scenarios such as gaming or video calls, as this may cause applications to be terminated and affect the using experience. It's better to use it before entering gaming or video call scenarios.

Avoid using the phone while charging
During charging, there is an energy conversion process which generates heat. Fast charging models have higher charging power and generate more heat. Using the phone while charging increases power consumption and causes more heat.

Choose a suitable video resolution
In high-temperature environments such as summer, avoid selecting high resolution or high frame rate in video mode, such as 4K or 60 frames. The higher the resolution and frame rate, the greater the camera's computational load and heat generation, 1080P or 30 frames setting could help reduce phone heating.
