I got AUB9 on a brandnew S21Ultra. The phone was factory reset before even installing anything, cache cleared. Cam drains battery ENORMOUSLY, without showing anomalous use. This phone is an utter catastrophy and goes back immediately for a refund. This was my last samsung phone EVER. Not going back. Exynos needs to finally die. The overall software is amazing, but this is all useless without a battery. I'll switch to the OnePlus 9 pro. Please, STOP telling people that avoiding smart switch will help, It's a lottery at best and there are a billion other issues that will never be fixed. Refund your phones if you experience this, don't listen to that pathetic: "iT nEeDs tO lEaRn uSAgE pAtTeRn" No other brand needs this, and no other brand has systemic drain issues. No, samsung, this phone doesn't need to learn anything, a 1300 dollar phone just needs to work out of the box, like other flagships. You don't deserve this, folks, ditch samsung and make them respect the customer, this is UTTERLY SHAMEFUL business practice.
Don't hesitate to return it and get a proper phone. Don't let those apologists and samsung fantards tell you that you're the issue or some app. A phone that comes out of the factory in this state gets RETURNED straight away for a full refund. Many details regarding the new exynos have been analyzed in detail and there are serious flaws about this new chip. Just energy efficiency is 20+ % worse than the snapdragon 888, camera processing is different and the gpu is 10% worse overall. Not to mention, the famous samsung overnight drain, which is still very much there. At least they're using ARM processors and killed off their useless custom chip division. I'd still very much prefer to see them nuke the whole exynos thing, but sadly this won't happen. But again, return it for a refund, you do NOT have to accept this.
Nope, not a "fanatic" at all. Just a disappointed consumer that got sold an INFERIOR chip that cost the same as a SUPERIOR chip (yes, watch the detailed analysis that you can find anywhere on the internet) If you're happy with your Exynos that's ok. The speed is there, but so is the devil in the detail, or let's say, the devils in the detail. There's quite a bit wrong with this new chip, but samsung has great marketing and damage control
