The cell towers are heavily powered so the signals go out but how does my phone with a much smaller power source transmit the data back to the tower?

Your phone only needs to talk to a few cell towers at a time so it doesn’t need a lot of power especially since they’re are usually a few close by in most developed countries. The cell tower on the other hand has to talk to hundreds and hundreds of devices and transmit that info to other towers/satellites/whatever to complete the task.
They simply need different power sources for different task.
