I've noticed a massive battery drain after the update since three weeks ago. I searched online and many ppl say this is because UWB (Ultra Wideband)issue. Now I have it turned off and checking will this improve the battery life. Please let me know if you guys facing the same issue and let me know your solution on this.

So far, everything looks fine to me. UWB is always turned ON. No massive drain battery but I do notice that it uses less RAM.
Super smooth animation👍🏻

After I turned off UWB it is better abit, recently don't know why I feel the battery performance drop again. Charge fully to 100%, on screen for few sec drop to 99%, within 2 mins drop to 98%. Gosh
