Hi all ! I have the Samsung Note 8 F version bought from pre-order. I have noticed that after the last update the battery of the phone is much less and above it gets warmer faster. I was curious about the capacity of the battery after a few months of normal charging without a fast charge from 20% to 100%. I read on the live battery topic about fg_cycle and fg_fullcapnom. Now I have 80 cycles with 3130 mAh capacity. I wanted to check this out and I bought the Stick Charge Meter Keweisi. I downloaded the phone at 1%, I close it, attached the stick and started charging. After 2h the LED turns green and the displayed battery charge is 2921 mAh. My question is why so little? Even I have lost in 5 months of using 300mAh or the batteries have a lower value than the declared one. Thank you!
LE:Sorry for my english!
have 2 F models and can't say I've noticed much difference in either of them, haven't done exact measurements though but both always running high performance mode and easily last a 16 hour day with regular 8 hour on screen time, what I have noticed in al my notes since the Note 2 is that after a while the first 10% seems to drop quicker from 100 to 90 but overall very stable, guessing that it is the phones battery management doing that
I have 4h sot with all on but maybe lost capacity fast this new generation of battery on S8,Note8?
Boss of Samsung mobile say battery lost 5% after 2 years of normal uz.Really?
Try checking with Accubattery app.

I also tried AccuBattery.In the application I had 3250 mAh.The calculation method used by this application is erroneous. If you load up to 80% or less will lower your value and if you drop to 100% in time will jump 3300 mAh. You can not check the battery capacity with the phone turned on because it is logical that there will be more consumers and will enter more mAh when charging. I will do a test with this stick charge meter but with the phone open and sure there will be more mAh to the situation when you have the phone closed. AccuBattery recommends that the phone be charged for a real appreciation to be carried on an airplane.
Hi. I have the European dual SIM version of Note 8 SM-950F and also noticed this. Don't know what to do. Here's my AccuBattery info:
We have tested the battery capacity today with the phone open. I downloaded it up to 1%, I installed AccuBattery and connected it to Stick Meter Keweisi. When I made the green LED I pulled the phone from the charger. I mention that as long as the phone was loaded I did not walk to him. I attach the result.I notice the difference between Stick and AccuBattery.
What build are you on? Just thinking if sammy is messing/patching with charging/discharging limits due to the stupid deep discharge?
I have an European version note8.
Accubattery says 3062 mah.
Fg_cycle is 81 and fg_fullcapnom is 3025.
I've had the phone for 4 months. When I bought it fg_fullcapnom was 3250 mah
Is it defective?
I have exynos Note8 F with vers.N950FXXU3BRA8.
@PlutoDelic,everything that's possible. I can not believe you can lose 300 mAh in 5 months with normal loads.

Check this out!
I found myself seeking threads in these forums about different ROM's and SOT obtained. The results were way different between different users, some claim to get 2.5h SOT some 5h SOT under normal circumstances.
Under normal circumstances I never get more than 3h and I suspected that my worn battery (598 charge cycles according to "Charge Cycle Battery Stats" app) was far from the original 3000mAh.(Thats a manufacturer stat obtained in perfect conditions, real world must be around 2800mAh)
I needed to measure the capacity left in mAh,so I bought a USB ammeter power meter (Keweisi white digits, but you don't need it, I'll explain later).
Using the Power meter, to measure properly you need to avoid thermal loss and power loss when charging:
- Note 5 completely discharged at 1 or 2% battery left.
- Disconnect the Fast charge option in Android.
- From start to finish keep the note 5 Switched off.
- Use an USB low power charger, mine was charging at 0.8A
Results: 1800mah that's far from the 2800mAh(3000mAh) when new.
(Same test I'm getting 2200mAh out of the original 2800mAh on my old Galasy S5 Neo.)
You don't need USB ammeter, Android has a builtin ammeter calculator(estimation).
Today I depleted the battery (2% left) of my note 5 again (Rom based on Android 7.0) and under battery usage I added all the "Computed Power Usage" in mAh giving the next results:
mAh
557 Cell standby (I worked underground today)
333 Screen 2h53m (30% brightness and auto brightness on)
271 Device Idle
221 chrome
203 Android OS
43 Google Play Serv.
39 Androyd System
27 Youtube
20 Yahoo Mail
20 Wi fi
17 com.android.systemui
Total: 1751mAh
This result shows that the phone itself makes a good estimation of mAh juice available in you battery.
As an anecdote I run the same test that Jerryrigeverything in YT with his Note 5(6 month of use): Playing a 2k video in 100% brightness( auto brightness off) with sound and in Flight Mode(not even wifi). He gets 6h20m, I surprisingly get 6h. But those test are only worth to compare Note 5's
Conclusions(my own and humble): Surprising degradation of my battery, specially compared with the results obtained in my S5 Neo. According to "battery university" (a good scientific source of information about Lithium-Ion) I might have shorten the life of my battery abusing of the fast charge mode.

Same here, the problem is that is quiet impossible to find a genuine battery for replacement. All those on amazon and ebay are crap.

That's the next step, find a good provider and compare capacities.
What I know so far is that there's 2 different battery models:
EB-BN920ABE The most common, but most reviews complain about being 4 or 5 mm shorter, ...less volume less capacity.
EB-BN920ABA Difficult to find, It seems the original replacement according to this picture:
https://ae01.alicdn.com/kf/UTB8YQ_yanzIXKJkSafVq6yWgXXa0.jpg The original is the right side one.
I found a Canadian provider who seems serious (free of fantasy marketing) who also ships worldwide, it looks like the original, (or a extremely good copy) I'm going to take the risk and try it:

I'll post results in about 6 weeks....

How did it go? Those eBay batteries tend to be pretty bad in my experience.
Finally someone else is concerned about note 5 battery capacity, i replaced mine with an original one in feb 2018 from a nearby samsung service center for $40, i used Accubattery app to measure and compare the battery capacity of the old vs the new battery.
After two years of usage and fast charging enabled in all of charge sessions, the old battery was giving me 76% (2291 mAh) of the original capacity, while the new one is giving me 89% (2675 mAh) right now, the weird thing is that it was giving me 90% right when i purchased it, i dont know if this is normal or not.
As for SOT, the old battery was giving me 2.5 hours on average, with an average of 17 hours of total usage, the new one gives me 3.5 to 4 hours with an average of 20 hours of total usage (disconnect at 100% from charger and drained to 1% or 2%)
Hope you find this post helpful

I'm in the same boat as you. My battery life blows and I am looking for a decent replacement so I don't have to buy a new phone. How did that one work out for you?
Hi all,
As my original battery with three years old, wasn't in good shape, so I decided to buy a new one on ebay and found this one with extra power. So Mi5 has an original 3000mah and I bought the 4800mah so I believe that I can achieve a full day and more almost half one, because with original one I always got 1 one day.
Now how can I check the true power of this new battery I used some apps, like ampere, accubattery, kernel toolkit and all assume this new battery as a 3000mah.
If new battery is in picture then you bought a 3000mA else a 4800mA battery is bigger then original 3000mA
GGelmi
Now way a 4.8 would fit
MIUI kernel fakes calculated battery capacity so it won't ever report proper values. That's why.
Anyways, buying DUPER MAXIMUM CAPACITY battery is always a fake and also you're in danger of burning your leg/house/car etc due to untrusted factory niche products.
Phones have batteries that usually worn out in usage, but getting good battery health in device is lucky for some only, you can measure battery health in apps like accubattery while charging, report your battery health here and age of device and type of usage.
My device battery health is 93% is it okay or i have to replace with new one, only 2 days old device, has 8 more days of return period.
I wouldn't trust too much on those kind of apps, you can compare the measurements between different apps and they will be different always, so it tells me that they are not so accurate. For example, since my phone was new, I got the same "battery health" status as yours, coincidence? I don't think so, for some reason this app can only read our batteries with 93%. I would recommend you to test your battery with different types of usage, light and heavy usage and compare it to the other users that have posted they SOT here.

I have 94% on accubattery app. I uses a USB metter tool and i have +- 3700 mah After a 0 -100% charge session.
With that i have 10hr of screen on. I have m'y 9t pro since 2 week. Global Rom on 11.0.3.
I'm happy with that. Maybe they keep a margin so as not to discharge the whole battery. for autonomy I believe it is important not to install version 11.0.4 which seems drained the battery

Hello all,
I got my self a Find X3 Pro a few months ago and I noticed that Accu Battery Pro and Aida 64 Battery, never reach the min capacity of 4400mah or typical capacity of 4500mah
Is this thing a issue ? Or my battery is degraded from brand new ? Or is this a software incorrect reporting issue ?
Thanks in advance !
Make sure to let it charge for about 7 minutes after it reaches 100%. The phone is not actually fully charged when it reads 100.
See here, after the first charging graph
Oppo Find X3 Pro review
The Oppo Find X3 Pro employs a similar display to the one we enjoyed on the Find X2 Pro. It's a 6.7" LPTO AMOLED screen of 3,216 x 1,440 px resolution or...
www.gsmarena.com
Then check again the meters. If they still read 4200, then you may have a degraded battery.
Also, consider that even if the phone is "new", it may have been produced a long time ago (like a year ago or more), thus suffering from some battery degradation already.
I always make sure I let it charge for about 10 more minutes at 100%. Still between 4000mah - 4200mah it displays.
Recently I replaced the battery for an old Mi 5s Plus and after a few charges (3-4) it will show the correct mah of 3800 (~3792mah)
So, did someone actually have these apps display the correct rating of the battery ?
I will give it a try tomorrow, but my phone is 1.5 years old at this point, so I don't expect to see anywhere near 4500 for sure.
I checked mine, but only 2 cycles it showed 89% The phone is 8 months old.
Thank you for your feedback...
My phone is barely 2-3 months old, should I try for warranty ?

Try to charge slowly to 100% using a 3A cable or less and leave it in charge until Aida64 show complete charged, then check charge counter how much mah show. Normally the counter will be a little less respect to declared capacity, like for hard disk the real capacity is not the full declared capacity. My X3 pro is used and charging to 100% show less of 4000 mah but battery life isn't bad.
18 months old phone, about 84% health (only one measurement though)

I'm sorry to tell you but you are mistaken, my ex Red Magic 3 phone indicated my rated capacity for battery and my recently replaced battery for Mi 5s Plus also indicated 3792 mah out of 3800mah, so I presume the issue comes for a incorrectly stored phone when I purchased it or old batch.
I always charge slow or at 1.8A because I'm never in a hurry, I even charged it at 500mah overnight and it went to just 4115 mah out of min 4400mah

No it depend from device to device and also from update cause it change also with kernel version. When I have OnePlus 7 pro always charged slowly bu never reached the full capacity of charger counter, this changed when I tried Oxygen OS 12 India beta, the battery show 4500 in charge counter exactly like the battery capacity. So it can depend from many factors and isn't simply to understand how really battery life is.
Thank you for all of your support and answers !
Yesterday I installed Battery Guru 2.0 and seems a more decent app than AccuBattery, will keep monitoring
AccuBattery and Battery Guru 2.0 tell me that I only have 1598mAh.
Aida64 tell me 3504mAh.
I don't understand...
I only know that my battery life is poor. I arrive with 20% or less at 8:00pm.
It is also true that I have many IOT applications always active, as well for the smartwatch, wifi, BT and GPS always on and also Always On Display all the day.
Cheers.

DO not forget to check the dual cells in the settings of the apps (accu battery and battery guru)
But even so.... 1600 mah x2 => ~3200mah
Very very unusual for this phone and battery
