So basically the numpties running the O2 network in my town sent out a message about 3 years ago saying they were going to improve the signal and as a result of this work the signal might be affected. I went from 4 bars to 0 and it never went back up. I renewed my contract with them back in November and as signal was ok for internet browsing, surprisingly , I thought it be ok to stay on their network, Now however recently the signal dropped so low I didn't even get 4g at all and the battery level just keeps on going down in rapid amounts of time which I understand is due tot he phone automatically searching for more signals or looking for better stations to connect to. Is there any way of reducing its ability to do this? I realise I may end up not getting phone calls but I lost 30% in the space of one day the other day and it was barely used. I already have background data usage settings turned off. Reduced the level of light and have various apps i power saving mode with dark themes. I also have it in stamina mode to better the battery by reducing its performance.

Any ideas anyone? Thanks in advance.
 
It sounds like you're dealing with a frustrating situation with your O2 network signal and the impact it's having on your device's battery life. Here are some strategies you can look into to help alleviate the battery drain caused by constant signal searching and maintain some level of connectivity:

1. Switch to Airplane Mode with Wi-Fi​

  • If you don't need to make calls, consider putting your phone in Airplane Mode and enabling only Wi-Fi. This way, your phone won't constantly be searching for a cellular signal, which can drain the battery.

    2. Manual Network Selection​

  • Go into your network settings and change the mode from automatic to manual selection. You can then choose the O2 network specifically or even consider switching to a different provider if available. This prevents your phone from constantly scanning for better connections. Steps to do this:
  • Go to Settings -> Network & Internet (or Connections).
  • Select Mobile Network -> Network Operators -> Search networks and choose the desired network.

    3. Enable 2G Network Only​

  • If you only need to make calls or send texts and don’t require data, you can force your phone to stay on 2G, which requires less battery power. Steps to enable 2G:
  • Navigate to Settings -> Mobile Network -> Preferred network type and select 2G Only.

    4. Limit Background Apps​

  • You mentioned you have disabled background data for apps, but ensure that there are no other applications running in the background that might be using resources. You can manually close apps or use a task manager tool.

    5. Battery Optimization​

  • Make sure to review all battery optimization settings. Some devices allow more aggressive battery saving settings that can limit connectivity more effectively. Steps to check settings:
  • Go to Settings -> Battery -> Battery Usage -> Optimization and apply it to all apps, especially data-heavy ones.

    6. Update or Reset Network Settings​

  • Sometimes, network settings can get corrupted. Consider resetting them which may improve your connection stability and battery life. Steps to reset network settings:
  • Go to Settings -> System -> Reset options -> Reset Wi-Fi, mobile & Bluetooth.

    7. Use a Signal Booster​

  • If your area has persistent signal issues, consider a network signal booster. These devices can help strengthen the signal in your home.

    8. Contact O2 for Assistance​

  • Finally, it’s worth contacting O2 customer service. They may have insights or updates about the signal issues in your area and could provide solutions tailored to your situation.
