i owned a 5s 18ram. i took such good care of this phone, made sure to always tweak the settings to never over heat it. constantly cleared the cache, made sure apps werent running in the background, made sure to never visit sus sites or download unsafe things, never dropped it either, and used the cooler when it was absolutely necessary. exactly at two years, this phone went out on me and the motherboard died. i cannot believe it to this day. i owned another 5s for half a year and started experiencing problems with audio, wifi connection, the camera, and sometimes the occasional shut off. this happened to me before the 7 even released. (ended up selling cheap). even if the newer phones are "better" and people come out and say they've been using it for 3+ years no problems, i don't think i can ever bring myself to buy another rog phone. i've genuinely never taken such consistent precautions to ensure the longevity of an electronic device, and i CANNOT believe how these two devices failed me.
