In those screenshots, your cellular signal strength is very weak. That will drain your battery. Put your phone in Airplane mode and use WiFi.

Depends on the apps you have installed that are using the battery. Post a screenshot of Settings > Battery, showing the green battery graph and the top app consumers. Apps noted with background activities are using your battery even when the apps are not opened. Meta apps have already been noted as being unusually power hungry where they tend to spend time harvesting data about the user as opposed to performing the simple operations of the app. That is just their business model for revenue generation though, and don't know if that is the case for you.

I find it fascinating that the algorithm can select a "Top-ranking reply" in seconds..... Makes you wonder. We posted very similar answers at almost exactly the same time.


I don't mean that your answer isn't deserving. It most certainly is.

It is the green battery graph that is needed to show the rate of drop over time. You do have the suspected Meta apps as already seen by others to drain your battery and are using background processes to continue to use the battery when they are not open.


The Home & Lock Screen usage may be an indication of a Widget that you have running on your Home Screen. Review the number of those you are using and pay particular attention to a third party one that may be needing constant updates.


The easiest approach to take is to remove an app and compare your results. The other method is to perform a factory reset with a clean install to get a base time reading of battery usage, then add the apps to see their affect. With this method it is best to use an archived backup with a computer so the iCloud backup is not overwritten.


And on top of that as noted by IdrisSeabright, you are at a 1 bar cellular reading which means you are using the maximum amount of power to make that connection. The closer the tower the more bars you will have and the less power is needed to transmit that signal. The distance of 4g is much greater and requires less power to transmit to the same tower. If you have the option to turn off 5g, try that and compare your results. I doubt you will see much difference in speed and you can compare the battery consumption.

I totally agree with you. You also added the important point of signal strength affecting performance. The farther away the tower is the more power is required to make that connection.

Thank you for your help and believe me I did all options makes battery life better like no meta apps on background no 5G no always on display no rais to wake

all settings which I did to reduce this drain and I found the problem it’s happening while using any application even reading comments maybe next few days I will go to apple services and try to talk with maintenance guys about it

thanks again for your help and time
