I've just lost 25% battery after updating my S23 ultra. It's losing power fast now. Plugged it into my 45watt charger and it's not charging as fast as it should even though it's saying superfast 2.0. Taking ten minutes to do a 3% top up. Wtf man, was debating whether to install the update or not. So far it's the worst update I've experienced. My phone better not be trashed after this. Fuming 😡😡😡😡😡😡😡
