(Update: Fixed) Battery Drain & Overheating Issues on iPhones – Official Response

Ever since the Tuesday’s patch, you might have noticed that your iOS device (mainly iPhones, but there have been some reports of iPads too) is not only draining the battery too fast, but also overheating when Hearthstone is launched. You aren’t crazy, and your phone is not broken – it’s a problem with the game.

Good news is that Team 5 is already aware and they’re working on a fix. Still, if you want to help, you can leave your feedback & device info to speed things up. There’s a thread on official forums in which you can do just that.

Hey all,

Thank you very much for the reports on this. It has been forwarded on to the Hearthstone team.

For anyone new coming into this thread, please feel free to post your iPhone model if you’re seeing the same symptoms after the latest patch.


While there’s no ETA on the fix yet, given that iOS users are a big part of the playerbase, I’m sure that they will want to fix it quickly. We’ll keep you posted!


Hotfix was released – iOS devices should no longer drain too much battery & overheat.

Hey everyone,

Earlier this morning we released a client patch for iOS devices to address and fix an issue that was causing iOS devices to overheat and drain battery power at an accelerated rate. iOS users will need to download this new patch in order for the change to take effect.
