To clarify this, Digimon can commonly Digivolve in two main ways.

Wild Digimon can Digivolve on their own if they grow old and strong enough. But it becomes increasingly more difficult to reach the next stage and takes a lot of time. On the plus side, this one tends to be permanent as it becomes their default form.

Partnered Digimon can draw upon their human partner's energy to temporarily force themselves to their next stage. While they will devolve if that energy is depleted, it does allow them to go to their maximum level whenever they want. Of course the greater the gap between their regular form and their evolved form, the harder it is to maintain.
