- 📉 Wi-Fi speed may decrease when there are a large number of connected clients.
- 🔋 Wireless battery discharge occurs significantly faster.
Using Bluetooth to save power
Although this method provides the lowest data transfer speed of all three options, it can be useful in situations where you need to conserve your smartphone's battery or when your computer's Wi-Fi module is faulty. The Bluetooth protocol consumes significantly less power, allowing iPhone 8 work in modem mode much longer without recharging.
To get started, you need to pair the devices. On your computer, turn on Bluetooth and start searching for new devices. Your iPhone should also have Bluetooth turned on and the Personal Hotspot settings window open (for visibility). When the computer detects the phone, click "Pair" and confirm the matching code appears on both screens.
After successful pairing in Windows, you need to go to the Bluetooth devices control panel, select your iPhone and in the context menu (right mouse button) select the item Connect via -> Access pointOnly after making this selection will a connection be established and internet access available. Simply being paired does not guarantee data transfer.
Why is Bluetooth slower than Wi-Fi?
The Bluetooth protocol was originally designed for transmitting small amounts of data (contacts, audio), not for streaming internet traffic. Its throughput is limited by the physical characteristics of the radio module.
Solution: The computer does not recognize the iPhone
A computer not detecting or connecting to a smartphone is a fairly common occurrence and can be caused by software glitches or incorrect settings. First, try the standard procedure: restart both devices. This clears the network service cache and often resolves the issue on the fly.
If rebooting doesn't help, check your privacy settings. iOS has a "Maximum Compatibility" feature in Personal Hotspot. When enabled, your phone uses the 2.4 GHz band, which is better seen by older devices but may be less stable. Try switching this setting. It's also worth checking if background data usage is restricted.
In the case of Windows, the problem often lies in the drivers. Open device Manager, find the "Network Adapters" or "Portable Devices" section.
