That's very significant improvement. Which model are you using?

I am still at the sideline since i am using iphone X with 81% battery health left. Afraid that battery draining will be accelerated.

HERE! I thought it was my wifi problems. I keep having disconnecting issues when im doing whatsapp calls via Wifi, on 5GHZ. Previously didn't have this issue.
Surfing i am not so sure as I don't surf with my phone much at home.

Maxis. And im using Wifi la, that's when i experience the connectivity problems
Using Maxis seems decent and ok.

Just in case anyone is interested, whatsapp video/calls via wifi is known problem after the update.

No one seems to have battery problem with 14.0.1 here?
My phone now will go from 50+% right down to 0% and shut down, won't power up until it is charged again. iPhone 7 with battery health at 91%.
Now anxiously waiting for another update.

Guys, the YouTube app finally allows us to watch in 4k resolution (2160). My iPhone 11 liquid retina screen (sub HD) shows this option. Just thought of letting everyone know.
