[Samsung Galaxy S22] dragos281993:
Mine is an SM-S9010. I rooted it and did some work on it. I turned off cores, underclocked it, turned off adaptive battery and so on. With all the things I tried, the SOT differs from charge to charge. I stopped even gaming altogether on it. I managed to get 30 more minutes out of it.

So the average SOT for me sits at 4h. I've got the Prime core and the last Middle core turned off, the Little cores underclocked to 1.5GHz and the rest to 1.9. The phone still overheats but the drain is slightly better.

Then there's the idle drain. The main culprit is Google's notorious Play Services crap with its services framework and all the other Google BS. I even installed a module to let it be optimized/dozed. It worked half the time. The other half the drain was even higher than before so it did worse than good. Now I've got Battery Guru installed and this thing monitors everything I need, plus it has a lot of stuff embedded in it, like the Quick Doze mod, power saver and Sensors Off with the screen off, etc. I've got the Powersaver on after the screen turns off and Data saver, and the idle drain sits at ~1%/hour. It goes at 0.7-1%/h, during the night unless the Play Services start spasming again, and they tend to do that a lot. And before having someone suggest a fix, please don't. I tried them all. They're just temporary solving the issue.

So yeah, there's no way in HELL someone can convince me they get 7-9h SOT cause that's just silly and exaggerated lying for a reason I don't understand.

In a 20h time frame the battery will lose 30% while the phone is idling. That includes ~10% which goes to some music listening and calls. I'm then left with 70%. After cutting off the 10-15% at which I plug in the phone, I'm left with ~60% of actual battery for the SOT. That means ~2150mAh. The battery is simply too small to be capable of anything more.

If you watch hours of YouTube, yeah, the SOT will turn out better because you're barely touching the screen once in a while and the CPU does the bare minimum and nothing overheats or goes into seizure mode. And the longer you use it in a smaller time frame, the better the results. When you use it over a longer period of time, go from idle to active use, idle again, and so on, that's when things start to take shape, so to speak. Then the moment you start scrolling and loading and loading things on Reddit or TikTok for example, or you browse the web, switch between apps and so on, things also change. The CPU will jump from a range of frequencies and produce more heat. The battery will share some of that heat and thing will get hot relatively hot soon, especially if it's hot outside. That translates into even poorer battery performance cause the hotter it gets, the worse the active drain is. And also, the lower the percentage, the worse the drain is too, I have noticed since I got this piece of crap phone. But yeah, if outside it's hot AF, the phone will be hot too. Today here where I live it's 30C right now. Using this thing and doing nothing intensive on it still gets it hot. It's too small to dissipate heat properly. Those saying "not heat here" etc, it's not possible unless you live in a slightly colder climate.

Not to forget to mention, I debloated this thing, removing pretty much everything Samsung included and I left only their bare minimum BS. Did it solve anything? Yes and no. It's a small difference but definitely not as big as I was expecting. It mainly reduces the idle drain, but like I said, the difference is extremely minimal.

I used a Pixel 5 last year. It was a great little phone. The battery life was fantastic on that thing. It was basically the first phone I've ever had with such a great battery life. The I moved to an iPhone 13 Pro. The one was even better. I never had to worry about running out of battery. Then after getting bored with iOS, I preordered an S22. Did I even consider the battery life? Absolutely not.

In conclusion, if you keep trying to find a solution to the problem, you won't fix much. Thing might improve today but tomorrow you'll be disappointed again the cycle starts again the next day.

The 8 Gen 1 built on Samsung's 4nm architecture is absolutely rubbish. It's terrible in terms of efficiency and when you pair it with a tiny battery you get a Galaxy S22, the devil child sent on Earth to destroy your mental health.

So don't bother trying much. Just use the phone as is try to use it as is. Just have a power bank with you when you're away and you're fine. Otherwise you won't enjoy the phone one bit. I, for instance, got to a point where I took it out of the case and now I use it with just a screen protector and the rest completely unprotected. If I drop it and it gets smashed into a million pieces, I don't care. Cause this is the worst phone I've ever had In my life. It's hard to like.
