Unfortunately, this is a necessity on so many Samsung phones (Exynos AND Snapdragon, but more towards Exynos).
So many phone brands in the past have handled battery better than Samsung. There is no consistency to Samsung's phones that one cannot strictly point towards mobile data usage or software tweaks as a reason for battery longevity. I'd site poor QA of cheap hardware and software bugs as the reason why.
Of all the brands I have ever used, it is always Samsung where every phone has to have so many features turned off. And it appears this isn't made any better by efficiency cores taking a back seat these last few generations. Of course you'll get plenty of people saying, "oooh, I had 11 hours SoT" having spent most of their day indoors on WiFi with automatic brightness bringing the screen brightness down.
The S25 base model, in my opinion, is a meaningless and overpriced experience. It still has 25w charging to differentiate itself from the S25 Plus, yet the A56 has 45w charging. Bizarre. Also, the battery is only 4000mAha - deal breaker! Considering how expensive the phone is, the AI will be gimped unless you pay a subscription fee (a fee that allows you to pay Google to send more of your private data 😂) and if you're lucky you may get 3800 out of that 4000mAh, by the second year of owning that neutered S25, your battery is going to be struggling to get through a day using mobile (cellular) data.
A couple years of effectively miniscule phone hardware updates, too much leaning on consumer subsidised AI (Gemini in the Galaxy series isn't free, let's be real... and that's before subscriptions) and let's be honest, awfully slow software support (Samsung is almost a year behind Android 16) and a total lack of innovation, and Samsung is becoming more and more irrelevant by the day and even worse value for money when looking at rivals.
Keep playing this game Samsung and droves of people will look elsewhere.
I am on a A54 and wanted to go the S25 route but was shocked at the specs... and sure enough, the base S25 sucks. I've already spent two years struggling with a 5000mAh phone with the horribly inefficient Exynos 1380, and... there's no point but to wait for One UI 7 and stick with this slow phone for another 2 years.
Disabling 99% of apps, all sorts of features, offline finding, 5G, always use dark mode, Bluetooth and WiFi scanning... geez, this feels like the naff Android experience from phones from 10 years ago. What a joke. And now we have £800-900+ not-flagship flagships, that will surely nag you via the UI of your OS should you not bow to the annoyance of Galaxy AI and Gemini subscriptions notifications.
If you enjoy your phone, I am glad. And I'm sure this won't change that for you, but I am frankly disappointed by all of this unwaranted Android kingdom that Samsung has inherited.
