Battery usage appears reasonable, but I've noticed it drains a bit faster when playing for extended periods. I encountered an issue with the app crashing unexpectedly, which left me frustrated, especially during a critical hand. The game does a good job of providing a balanced experience, but sometimes it feels like luck plays too significant a role in the outcomes. Customer support has been responsive to my queries, which is a definite plus, but it took a while to get a solution regarding a payment issue.
