How long does S21 Ultra battery last?
The results were impressive: the S21 Ultra easily withstood a whole day of heavy use.
Just got a refurbished Galaxy S21 Ultra, and I've noticed the battery drains pretty fast. It lost about 5% just while I slept, and it's always empty before the day ends.
Battery capacity: 5000 mAh.
No! The battery is not at risk of overcharging if you leave your phone plugged in overnight. Once it reaches full charge, the charging process stops and only reactivates periodically to maintain the battery at full capacity.
It is powered by a 4000mAh battery. The Samsung Galaxy S21 has a 25W fast charge feature, a 15W wireless fast charge, and a 4.5W reverse charge option. Through the ViserMark testing protocol, the Samsung Galaxy S21 battery lasted almost 37 hours with a display refreshing rate of 120 Hz and 38.5 hours with 60Hz.
For Android Devices: Slow charging generates less heat, which is one of the factors that can degrade battery health over time. By charging your Android phone slowly through a computer, you reduce the heat generated during charging, thereby potentially extending the overall lifespan of your battery.
Dark mode setting has become an increasingly popular battery-saving feature in smartphones. But the option is unlikely to make a big difference in extending a phone's battery life as promoted by both Android and iOS, according to a study by Purdue University.
The maximum battery life of a Samsung phone can vary depending on the specific model, battery capacity, and usage patterns. However, most Samsung phones typically have a battery life of around 2-3 years before they start to show signs of decreased performance and reduced battery life.
Galaxy S21 Ultra goes out, makes space for S22 Ultra
A previous leak suggested that Samsung could be mostly relying on its Exynos 2200 chip, which has a new GPU that is based on the AMD RDNA 2 architecture. Leaked website data suggests that the cameras could not be much different from the S21 Ultra.
Cons. Somewhat bulky and slippery. The image processing needs further refinements. We don't miss the microSD slot, but some of you might.
Why did Samsung stop selling the S21 Ultra?
Samsung is starting to phase out the Galaxy S21 Ultra in anticipation of the Galaxy S22 Ultra that's coming on February 9. Samsung is no longer selling the Galaxy S21 Ultra on its official websites in France, Germany, the UK and the US, among others.

Samsung Galaxy S21 Ultra Specs
It's a solid and premium-feeling phone with a unique (for the US) superzoom camera, a gorgeous screen, and future-forward network chops. The S21 Ultra sets the bar for Android performance in 2021 and its superzoom camera will lead you to look at the world in new ways.
With a Power Delivery charger, you can charge your S21 extra fast. The fastest charger is the 25W Super Fast Charging charger from by Samsung. It allows you to fully charge an empty battery in just over 1 hour. With a Power Delivery charger, your smartphone is fully charged after 1 hour and 30 minutes.
Most Smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity.
The phone will only draw what it needs and then once full will stop and only trickle charge to keep the battery to full. I use normal charging on a Samsung Wireless Charging pad.
As soon as the battery reaches 100%, it stops charging. At this point your device runs on AC power rather than battery power. Of course, eventually, whether or not you're using it, your phone will drop to 99%. At this point, your phone will "trickle-charge", as the charger repeatedly brings it back up to 100% again.
Galaxy S21 users can also modify other display settings, such as reducing the screen brightness when not required. Some users prefer using their phones at full brightness even indoors or in low light, but this can drain the battery and cause eye strain.
S21FE & S23FE will get 4 years OS & 5 years security updates policy ~ Clarity. So there's aSamsung Knox site which shows that S21FE 5G will get guaranteed OS upgrades till Android 15. And there's another Samsung site -Samsung Newsroom it shows that S21FE will get 4 OS upgrades & 5 security updates i.e till Android 16.
So here's a handy rule: Don't start charging until your battery reaches about 20 percent — and try to stop when you get to about 80 percent. This will make sure you maximize each cycle while keeping the battery free of stress.
What is killing my battery capacity?
Here are some of the most common ones: There are too many push notifications and alerts draining the battery. There are too many apps running location services. There are too many apps running in the background.
So at what percentage should you charge your phone? The best practice for preserving phone battery health is to plug it in at around 20% and charge it up to 80-90%. This is especially important if you use fast charging, as charging from 0% will cause a lot of heat, and from 80% up, fast charging becomes less efficient.
The health being at 97% is considered a healthy battery and there is no need to be concerned.
Changing from light to dark mode reduces the phone's power consumption by 42% at 100% screen brightness. When the brightness level is 50%, switching from light mode to dark mode saves 9 % of the battery, and when the brightness level is 30%, the saving is only 3 %.
You can also eke out a bit of extra battery life by turning off the active listening feature of Siri — if your iPhone is always listening for you to say “Hey Siri,” then that uses up more of your battery.
