Implement timeout criteria to avoid repeating app actions that might drain the battery, e.g. poor data connectivity resulting in numerous retries vs. a timeout or retry policy to stop after 3 failed attempts, wait, then retry after a few minutes. Possibly, extend the waiting period after every cycle. Alternatively, get relevant metrics from the device.

Additional points: - check communication frequency and real system needs. In many times less frequent wake up increase battery life. - check batteries specifications. Different manufactures provide different battery life time and nominal capacity. Usage of batteries with higher capability may increase time to battery replacement.
