That is your choice if you are unwilling to remove them to isolate the problem to those apps. Only the developers of those apps can resolve the problem, Apple cannot. The Social Graph that the apps use for each individual is very different and the data points used will not be the same. What prompts the app to wake up in the background on your brother's phone to process new data will be very different than yours. Your issue will continue as long as the developer has not resolved the problem or you continue to use the app. It makes no difference what device you are using.
It is basic Troubleshooting 101 to identify the problem. You could even switch phones with your brother is realize it is not your device that is the problem. It is your data that those apps are interested in collecting and it takes battery power to do that. You have many more data points the apps are interested in than your brother, it is that simple.
