I've been using my iQOO Z9x with 6GB RAM and 128GB storage for almost a year now—it's been great for gaming and performance! Recently, I've noticed that my battery doesn't charge fully. It used to reach 100%, but now it maxes out at 98%. I typically use my phone for about 8 to 10 hours each day. Just last night, I charged it overnight but found out this morning that it only reached 98%. I did use it for about an hour while it was charging yesterday. Is this normal or is there something wrong with my battery?

Have you tried restarting your phone? Sometimes that can help recalibrate the battery. If not, it might just be a sign that it’s aging. I’ve heard other users say that even with reduced capacity, their phones still charge to 100%.
A drop to 98% after a year isn't too bad, honestly. Most lithium batteries degrade over time, and staying at 98% is impressive after so many hours of use. Are you experiencing any performance issues?

I did restart it, just to be safe! But I heard from another user that their phone dropped to 94% and it still charges to full, so I'm confused why mine isn't doing the same.
