[Samsung Galaxy S22] dragos281993:
I've got the 8 Gen 1 S22 and it's sufficient to say it's a terrible phone. It overheats, it gets stuttery most of the time probably because it's getting throttled, and the battery is bad. From 100 to 50% it's bad and from 50% and below it's terrible because it drains faster. And it's even worse when the phone runs hot, which is pretty much gonna be the norm in a hot summer environment. Then there's the last 5% which is non-existent because it's basically like a countdown in seconds from 5 to 0%. In other words, if your phone hit 5% it's gonna turn off in a matter of seconds if you don't plug it in ASAP.

So the math is kind of like this and note that I'm gonna talk about a period of 24h of use, both active and idle:

- you've got a battery of 3590mAh, the real capacity. I'm gonna cut that 5% right now because that simply doesn't exist. That means 180mA, which leaves you with just 3410mAh.

- 25-30% is the idle drain, and it's gonna stay in this range no matter what you're gonna try to do. Believe me, I tried EVRYTHING, even turning off cores and so on. The damn thing finds a way to drain battery with the screen off somehow.

- you're now left with only 65% of actually battery for SOT. That translates into ~2216mAh. That is all you have from a full charge.

- now the active drain is gonna be ~20%/h no matter what any battery monitor app tells you. That is 682mA/h.

*** This is all with normal use, which includes more than just watching videos, scenario in which the lack of touch events + the screen on will count towards that SOT recording and of course that's gonna increase the SOT. But that's kind of like fake SOT. When you start swiping up and down within apps, switching between them, browsing the web, which all means that you're getting the CPU to go from a range of frequencies, is when the actual real usage happens, so that's the true SOT of a phone.***

So, to get back to the math part, you're gonna get 3h15m. You're gonna watch some videos, I don't doubt that and that's gonna reduce that 20%/h to something lower, as long as there are no touch events. That's gonna get you over 3h30m. If you're watching a lot of YouTube and such, you can hit 4h SOT. But the average SOT for this phone is 3.5h.

That is terrible battery life for a phone in 2022. Samsung's node for the 8 Gen 1 was a complete fail and that is why Qualcomm went back to TSMC for the 8 Gen 1 Plus, and the efficiency gains for just a refresh of the same CPU, are insane. We're talking about 30% more efficiency. Insane! The 8 Gen 1 is pathetic and it's rarely gonna run the way it was meant to because it can't due to the heat it constantly produces. Paired with the small S22, there's not enough phone to dissipate that heat more efficiently, and therefore you're left with a choked out "beast". I'm no expert but I'm pretty sure that if I choke out The Rock and make him run with me on his back, he's not gonna perform very well, no matter how buff he is.

The bigger brother though, the S22+ is not gonna have the same issues. There's more material to dissipate the heat more efficiently and there's also a considerably larger battery inside. Not a lot bigger but big enough. You've got the same screen so the power consumption is gonna be different. Now all those percentages I mentioned above are gonna be based on the bigger battery. The idle drain is gonna stay the same but instead of 30%, that value would be ~24%. If that 5% issue is the same, you're left with ~3100mAh for SOT. The active drain would then be 16%/h. If my math is correct, with some room for error, you'd be able to get 4h40m with the same usage I initially mentioned for the smaller phone. With those reduced touch event during the videos, you'd be able to get over 5h out of it on a 24h charge. And if that 5% issue is not present, you've got ~200 more mA which would give roughly 20 more minutes over 5h, for SOT. Not that bad.

That's why I regret getting the small phone. Not as much as getting rid of the 13Pro I used before it, which offered me the best battery life I've ever had in a phone, but I still regret it.

In conclusion, you either go big in the Android world, or suffer. Or you can get the S21 and have better battery life than the S22. Your choice.
