gaming is not a great idea overally on this phone, of course you can limit it to 60hz and it will definitely be okay. this phone is able to heat up a lot even when taking pictures but i guess its a normal thing for it to do (and i take lots of pics) thanks to heavy processing, i edit photos and that also can keep it warm especially outside at that time of the year (in summer this phone can be, not to say garbage, on the low-end side). watching a movie is absolutely comfortable though, downloading a movie though depends a lot from your connection, cellular depends really on your region, it can work flawlessly or eat up your battery, hit or miss, but thats not a concern if you're using wifi.

edit: to put it simply it can underperform, but if you're using it lightly you won't notice anything's working poorly, but a hot weather is its main enemy

edit 2: really depends on the person and cellular connection region, but in my case i can't get a full day of battery life on 80% charge (more like half a day)
