As per the specs of S21FE, it has 4500mah battery. But i have checked it in some apps, like "device info" (screenshot attached), "accubattery", both the apps showed battery capacity as 4370mah.
Is there something wrong with the phone? Should i claim the warranty?

I have the same figures. I guess for marketing purposes, they round the numbers.
That's typical even with a new battery.
Accubattery isn't that accurate perhaps and from the day it's assembled a Li starts to degrade; born to die. All you can do is slow the process by limiting top charge/low discharge voltages and cell temperature. In storage or use a lower temperature of 72F or so is best. However charging below 72F is not recommended, 82F is better. High cell voltage (>80%) and temperature cause the most rapid degradation.

Thank you for this info. That means i m not the only one getting battery capacity as 4370.
But i don't think they will round the figure to this extent. They could round it to 4400 as well.
Perhaps an app issue or Samsung really has put 4370 mah battery in s21fe

That could how much it actually degraded since being assembled. The battery info looks like a big improvement from my N10+'s. Samsung may be using improved battery monitor firmware and hardware. Yay.

Rated vs actual capacity...
Just check in my new S21 FE and I have the same figures....
From what I could find, accubattery and other battery info apps are reporting the "rated capacity" of the cell installed on this phone. Lithium-ion cells have a "typical capacity" which is the "total" ammount of mAh of the module, but due to cylces, production and performance issues manufacturers specify a "rated capacity", this is the actual ammount of usable mAh on that module and usually is a 20% margin under the "typical capacity".
I personally recommend you use an app called Battery Guru.This app does it's own estimation of actual battery capacity doing a calculation over a series of cyles. It's the nearest thing to the "battery health" Apple provides on iPhones. It also has a LOT of information about battery best practices and useful info in general.
You can verify this in this screenshot of a teardown from this video:

Hey, great app to monitor graphically the battery discharge... thanks for sharing!
Umm, is this app created to discharge the battery, or to see how it discharges?
If it's the latter, good job! If, however, it's the first... read up about Lithium Ion batteries!
Its an App for both!
And again, outside in "the World", there are not only Li-Ion Batterys. In my company we have many older devices with NiMH-Batterys.
And nobody say that you must discharge your Battery. Its only an Option. You can also see if your Li-Ion Battery is allready damaged or something else.
So, its an testing, monitoring and also discharging app.
You can still read the original Thread...
so just to clarify: DO NOT ATTEMPT TO DISCHARGE YOUR OPERATIONAL LI-ION BATTERY. li-ion battery life span is longest when charged above 30% (some people say that one shall charge at 40%). discharging battery to zero can damage battery.

What a coincidence, I believe I live in this "the World" you speak of! That aside, I assumed the purpose of my comment would be fairly clear. Many people don't know that Li-ion batteries are different from NiMh. If you post it in a forum with Li-ion battery users, I suggest you either put up a big warning in the first post, or a built-in warning into the app (haven't tested, so don't know if it's there).
Anyway, I'll try it and see what it does =]

Oh, about that, at approx. 21%, Li-ion batteries are most often irrevocably dead.

Hi, guys.
I've just replaced phone's battery with this "HSABAT 3800mAh" ... Everything is ok but I'm guessing the battery percentage info in system is adjusted to old 2300mAh value. I'm using AICP Oreo.
What I need to do in order to get accurate battery data??
Thank you in advance :fingers-crossed:
I think you have noticed by now that it all works without any additional settings.
However - i do not think the new battery is 3800 mAh - at least not in this phone (voltages). The battery tech has not evolved so much during these few years and the battery compartment physically does not allow so much energy. (you need to have certain amount of chemicals for any Ah).
Everything is OK, except for battery life... I guess this "HSABAT 3800mAh" was a rip-off.

I'm not sure if I should try another replacement battery.
It's a shame be forced to say goodbye to this nice device because of this.
Just buy a genuine battery, they are available on the internet (about $15-20). I have replaced my battery twice with full success.
Just stop and think a little bit before buying. Original battery is 2300mAh and your fake one is 3800mAh. How on earth you can pack almost double capacity into the same size battery? The same chemistry gives the same capacity in the same size. Simple. Forget about 3800mAh and if it holds charge properly just use your phone. Probably you still have 2300mAh in it.

You can use your current battery if it holds charges properly e.g. no sudden drop from 50% to 0%. I got my battery a year ago from this shop and it works fine https://www.aliexpress.com/item/32870459998.html?spm=a2g0s.9042311.0.0.1ec633edTwqvQZ
hi.
first sorry for my bad english.
i am new here...
i bye used pixel 2 xl.
it is very good, fast and strong.
wifi i have 4-5 hour SOT.
it is normal or bad?
accubattery sad i have 75 % battery capacite and this program is really good or no?
i have
location off
apps restricted (unused app)
apps notification off ( unused app)
dark theme
now (pls see screenshots) i have 1hr,5 min SOT. i have charged phone 95 %.
this is wifi.
thanks.

Some will disagree but I find accubattery pretty accurate after letting it run for at least a week. For a battery with approximately 25% battery degradation I think you're getting the expected battery life.

which battery i can bye to replace it?
is it here something good to change it?
Many people who had the battery replaced can no longer fast charge. There is a thread on here about it. Most likely because the battery is aftermarket and to my knowledge oem batteries aren't available and the ones you find online that claim to be oem are counterfeit. You could replace the battery with a good aftermarket from ebay but no fast charging, or send to google for oem battery replacement if that's possible where you live.

Please vote mentioning your charge cycle count along with actual capacity vs the rated capacity of 4905 mAh/18.88 Wh
That's an interesting topic. With my P4 XL, I won the actual capacity lottery and had a phone that started with 109% capacity.
My P6 Pro has (according to 3 weeks of Accubattery) about 102% actual capacity (~5110 mAh) after 21 sessions with ~1100% charged (~ 55000 mAh).
The design capacity by the way, as you can see in your screenshot, is 5003 - not 4905 as per your statement.
4905 is the MINIMUM amount that Google accepts/offers, 5003 is the "typical"
-> (typical = design)
I'd give it a 3.6
Not great, not terrible.
Wondering how everyone's battery capacity has been doing. Out of the box Accubattery stabilized around 99% for me but now after 4 months I've dropped to 95% (4755mah). This is much faster degredation than I typically see on my devices. 95% of the time the phone is between 20-80% charge, my chargers shut off at 80% unless I know I'm going to need the extra capacity. My unit runs hot quite often and Im thinking that it is wearing out the battery with all the heat. Curious what other users are seeing after some months of ownership.

Good to hear you are having more luck, 1-2% per year is what I am used to seeing on past devices under similar usage patterns.
If only Power Saving Mode let you choose whether to disable or enable auto-sync. Is there any way to somehow enable Power Saving Mode (to limit CPU to 70%) without disabling sync? I can't miss notifications but want to save some battery.
Running in anything lower than the optimized power setting really screws the N10+ up. More of an emergency measure than a normal operating state.
With a good battery you should be getting 10+ hours SOT if optimized... and days of standby time.

I get 5-6 hours MAX of SOT and 6 is pushing it. AccuBattery has my health at like 93% so the battery isn't bad by any means. I regularly let the phone put unused apps to sleep and I never game.
I really just want to find ways to squeeze the most life out of battery without crippling my ability to get notifications as they arrive.
Something not right. Even with a degraded battery needing replacement I get a lot more than that.

3440 mAh is 80% of the battery's original capacity and the end of its useful service life.

AccuBattery's estimate for mine seems a bit worse than yours, but 10 hours of SOT isn't something I've ever been able to get. My estimated capacity is 3,908 (94%) of 4,170 mAh.

That's not bad. It needs to be optimized more if you want to increase the SOT.
Try temporarily disabling Google play Services when not needed. It's needed for Gmail, Google backup Transport and Playstore but not much more. I always have Playstore disabled as it's a troublemaker. Any cloud apps running in the background are also skewing the battery life.
I use manual brightness control; excessive brightness wastes battery and pixels. I use dark mode and themes to conserve display, battery and eyes. Also use Package Disabler to disable about 70 apks I don't use.
