Guys, hi, I have a poco m5 right now, and it's time to change my phone. I have a choice between these three phones. I mainly use my phone for gaming (including heavy games like Genshin), and I'd like to have more battery life so I don't have to charge my phone frequently. Please advise me on which phone to choose from the list and it would be desirable for it not to lose much of its relevance in 3-5 years. p.s. The poco f6 costs $270, the poco f7 $376, and the poco x7 pro costs $317
