OPPO Reno14 Overheating During File Transfers?

🔍 Issue Overview: A Common Early-Use Pattern

As one Reddit user shared:

“When I first got the phone it was overheating quite a bit while transferring files. Ever since then, never had the overheating issue again.”This feedback reflects a typical experience: initial overheating that subsides after a few days.

⚙️ Why It Happens: Initial Setup Meets Heavy Load

After you set up a new OPPO device like the Reno14, the system performs several resource-intensive tasks in the background, including:

• Indexing media files for the Gallery

• Syncing data with OPPO Cloud, Google, and other services

• Rebuilding system and app caches

• Applying performance optimizations

If you perform large file transfers during this period—such as copying video folders or phone backups—your device may get warm. That’s because the CPU, storage, and wireless systems (Bluetooth, Wi-Fi, 5G) are working simultaneously, increasing power consumption and heat.

This is expected behavior and typically stabilizes within 48–72 hours.

🛠 Practical Solutions & Tips

Follow these steps to minimize overheating and battery drain during transfers:

1. Wait Before Transferring Large Files

Let your Reno14 complete its post-setup operations. If possible, wait at least 24–48 hours before moving large files or backups.

2. Transfer at Safe Battery Levels

Avoid transferring files when your battery is below 20% or above 90%, especially while charging. Aim to transfer at a charge between 30%–70% for better thermal control.

3. Enable Smart 5G

Go to:
[Settings] > [SIM Card & Mobile Data] > [Smart 5G]
This reduces thermal load by dynamically switching between 5G and 4G depending on need.

4. Monitor Battery Usage

Check which apps or processes are consuming the most energy during transfers:
[Settings] > [Battery] > [Battery Usage]
Restrict or close non-essential apps running in the background.

5. Avoid Heat-Prone Environments

Do not perform large transfers in direct sunlight or in poorly ventilated areas. Keep the device cool by staying in the shade and placing it on a hard, non-insulating surface.

✅ Final Word

Minor heating during file transfers in the first 1–2 days of usage is completely normal and temporary. By following the above best practices—especially delaying large transfers until after system setup—you can prevent unnecessary warmth, battery drain, and discomfort.
