This is all kind of in accordance to this recent review video of the p40 (different phone, same chipset)
Now one thing I've noticed is that if I use appassistant to launch these games, the poor performance disappears entirely. No lag anywhere, in Cytus, where before during fast sections it wouldn't even register taps 6-7 times per song, there are ZERO misses across the board. Similarly, no screen tearing or lag in any other game.
Wondering if the OS is optimized to cut power to the GPU and put it into limp mode during normal operation to save battery as I've noticed a dramatic difference in battery drop when using appassistant or not to play games. I mean naturally, the appassistant game center is doing its job but man that's a big difference.
Anyone have similar experiences?
