Pokemon-go – Why do Pokemon escape when I’m not moving

Pokémon can escape from battle, but only after a set amount of failed catch attempts. At current, there is no information on how this amount is determined, nor if it is based off the CP strength or rarity of the Pokémon.

That said, it would most definitely be influenced by the catching difficulty. You can also increase the chances of catching a Pokémon in several ways:

• Using a berry from your backpack
• Using a more powerful pokéball
• Ensuring the circle that appears over the pokémon when you hold down on the pokéball is at its smallest size, when you throw it.

For more information on the "catching circle", in regards to catching difficulty and chance, see our question on "What does the size of the multi-coloured circle mean?".

Your own captured Pokémon will not run away. The only way to lose it is transferring it by accident. Your journal is showing an instance of a wild Ponyta fleeing from battle, which can happen randomly if you fail to capture it too many times, probably more commonly with stronger Pokémon.

A good way to ensure a capture is using better Pokéballs and Razz Berries, but keep in mind that capture attempts can still fail and Pokémon can still flee even when using those items.
