Sounds kinda strange that only 1 game will make it hot. I have never had this issue, and this is the first time I hear of it. You sure your phone is working correctly?
I went in the history of beteri and plunder pirates uses 75 %!!! In 7 days ,everything works normally youtube other games and programs
hmm.. Im not a technician or an expert on phones, but that sounds weird lad Never heard of this before. Is your phone jailbreaked perhaps? could be some factory issues with your graphic ship or whatever its called. Plunder Pirates uses a graphic supported with the new ''metal'' (new phone gaming technology). Do you see shadows in the game?
Hey Falloutfilip, I have the same thing happen to my iPhone 5s. As I'm playing my phone gets extremely warm, but hasn't caused any issues beyond that. It's just from the graphics processor using lots of power from the battery and they both heat up. I've played for an hour or so re-arranging my base with my iPhone getting pretty hot and haven't had any problems. You should be okay, it's expected with a small device.
This can be caused because of a battery that had his best time. Or because of charging while playing. Or as @OneHitWonder said because of the lots of processing. Or all of the above
Thx all but i think i Repaired with deliting the geame and reinstalled it is not overheating as before
I am experiencing the same issues of excessive heat whilst playing plunder pirates. I had a iphone 4s prior and now upgrading to an iphone 6 and I'm noticing a perceptible increase in heat which is weird because the 6 has more efficient processors. If I untick the "enable shadows" in the settings the heat is reduced but still quite high compared to other games I'm playing. Looks like the developers need to further optimize the code and/or to allow us to tone down the graphics a bit.
Have tried reinstalling the game? It might be an issue with your phone. Because there are a lot of players on iPhone 5(s) and 6(+) that don't have this issue, which tells us it's not in the coding or because of the graphics.
