This mirrors my experience directly. Before smart phones, I found TomTom to be more user friendly than competitors, but they were slow to boot up, the battery was only useful for providing clean power vs the car electrical system. I tried using my TomTom for walking Navigation. The battery lasted long enough to reach my destination, but luckily I remembered my way back to the parking lot after, because the battery did not make it.

Google Maps on my phone works fine, and on my current Pixel 5A, I can navigate off battery for a three or four hours. Plenty of walking time to hit multiple points in a day of walking.

Maybe some day the TomTom app will be competitive with Google maps, but for now, Google maps is the reference by which all other mapping will be judged.
