iPhone 6s 2.4G Wi-Fi issue

Bluetooth interference can potentially cause Siri to stutter due to the disruption of the wireless communication between devices. Bluetooth operates in the 2.4 GHz frequency range, which is also used by various other devices such as Wi-Fi routers, microwaves, cordless phones, and even some baby monitors. When multiple devices are operating in close proximity and using the same frequency band, interference can occur.

Here's how Bluetooth interference can impact Siri's Voice:

1. Audio Streaming Interruptions: When you're streaming music via Apple Music or using Siri to play audio content, Bluetooth interference can disrupt the connection between your device (such as an iPhone) and the Bluetooth speaker or headphones. This interference can result in the audio stuttering, dropping out momentarily, or experiencing poor sound quality.
2. Data Packet Loss: Bluetooth devices transmit data in packets. Interference can cause some of these packets to be lost or corrupted during transmission. As a result, the receiving device may have trouble decoding the audio or Siri commands correctly, leading to stuttering or delayed responses.
3. Signal Weakening: Bluetooth signals can be weakened by interference from other devices operating on the same frequency band. If the signal strength drops significantly, it can affect the stability of the connection between your device and the Bluetooth accessory. This can result in intermittent stuttering as the connection struggles to maintain a consistent data flow.
4. Channel Congestion: Bluetooth uses different channels within the 2.4 GHz frequency range to establish connections. When there are many Bluetooth devices in close proximity, multiple connections can create congestion on the available channels. This congestion can cause interference, leading to degraded performance for Apple Music streaming or Siri interactions.

To mitigate Bluetooth interference issues and reduce stuttering:

1. Reduce Device Density: Minimize the number of active Bluetooth devices in close proximity to each other. Switch off or move away devices that are not in use or causing interference.
2. Increase Distance: Increase the distance between your Bluetooth devices (e.g., your iPhone and Bluetooth speaker/headphones) to reduce the impact of interference.
3. Update Firmware: Keep your devices' firmware up to date, including your iPhone and any Bluetooth accessories. Manufacturers often release firmware updates that can improve the performance and stability of Bluetooth connections.
4. Avoid Obstacles: Objects like walls, furniture, or large metal surfaces can obstruct Bluetooth signals and contribute to interference. Ensure a clear line of sight between your devices to optimize signal strength.
5. Switch Channels: Some Bluetooth devices allow you to manually switch to different channels within the 2.4 GHz range. Check the user manual or settings of your Bluetooth accessory to see if you can change channels to find a less congested one.
6. Use Wi-Fi 5 GHz: If your Wi-Fi router supports it, consider using the 5 GHz frequency band for Wi-Fi connections instead of 2.4 GHz. This can reduce potential interference between Bluetooth and Wi-Fi signals.

By implementing these steps, you can help minimize Bluetooth interference and improve the overall performance of Siri's voice.

The original battery of any iPhone 6s model is overdue for replacement. Also, that 83% is not healthy and probably the reason for the Wi-Fi problem. Apple recommends having the battery replaced at around 80% – so have the weak, aging battery replaced:

madhukj ~ Does your iPhone 6s still have its original battery?

And what's the Maximum Capacity % here?...
