In the article: "..the company can track your smartphone battery life.."

They ARE tracking my battery, all the time!

I looked into the HTTPS-trafic from the Uber-app (with MITMproxy) and it is one of the few that send my battery and charging status on a regular basis:

          "battery_status": "unplugged",
          "battery_level": 0.73,

It would be interesting to run a script that changed the battery status data in the HTTPS-trafic to make it look like it is dropping fast.

Just to see if there is a correlation with the price, waiting time and available drivers I am getting back.

And if so, get lower rates by running a script which lies to Uber and says the battery is plugged in and at 100%.

Then I would set up a proxy through my home server to change the battery-status based on my need

But isn't your need to always pay the minimum amount?

How do you proxy their traffic ?

I couldn't because they seem to use pinned certificates.

Read up on MITMproxy. It works best on Mac. For Windows I recommend Kali-Linux virtually so you don't have to build for Ubuntu. If you have problems just email me: morten(at)punnerud.net

They only force HTTPS, not their own sertificate as in Facebook and Snapchat.

Visit mitm.it on your phone (after you have set up a proxy through your pc running MITMproxy) to automatically ad a sertifificate to get it working, or generate your own if you don't trust the service.
