Hi guys
Recently I'm testing my game on iphone7, I found out that the phone heat up very soon even though I have not started playing it, so basically there are just around 30 static sprites. When I reduced the number to less than 10, the temperature drop obviously. Eventually, this problem is resolved by changing the renderer from Phaser.AUTO to Phaser.CANVAS, but I don't understand why the canvas perform better than webgl, and why it only happens to iphone7(on iphone6+ or 7+ are totally fine), has anyone had the same problem can explain it to me?
