[Battery Health] - S9+ comes with crippled battery? - Samsung Galaxy S9+ Guides, News, & Discussion

Found this method in a S8 forum and tried it on my new S9+
With a file manager go to root folder
Sys --> class ---> power supply ---> battery
Look for:
fg_cycle (number of charge cycles) : showing 5 on mine which seems correct
fg_fullcapnom ("real" battery capacity*) : showing 3322 on mine which is not right, should it be 3500?
BTW accubattery is also showing 3300+ mah capacity on my device.
Is my device faulty ? How is your capacity? Is this number reliable?

Mine is showing 3336

3 charge cycles and 3378 mAh capacity.
Exynos GS9+, got it on the 10th of March.
I don't think AccuBattery reads this file, but it sort of judges battery capacity based on charge times and all that and gives you an estimate.

Mine is 3310 and accu ie showing 3306
But I dont think that's the correct number you can check all the phones you want none of them have the correct capacity in that file. My s8 shows 2770

My s8 shows 2600 but I think that's fine because it's 1 year old and battery does age.
But I suppose a new device should have a 100% healthy battery?

Yeah I understand they use another method to calculate the capacity. It makes me more concerned because 2 ways agrees that fact that our battery is indeed only 95 of its rated capacity?

I thought they were reserving 200mah to give the 95% battery longevity claim. Meaning the S8+/s9+ get 3300mah and the S8/S9 gets 2800mah.
I could be wrong though, I just remember reading it.

Yes but that file doesnt change, so whether its 1yr old or 1 day old it should show the same value. My s8 is also a yr old

That shows 3500mah for everyone, it's just a preset specs...

my estimated accubattery capacity is also 3300 mah wtf! for all my phones it makes sense they were at 100% or a little above when new and the estimates capacity slowly decreased over time, for example my s7 is now at 70% and my note 8 when new was 101% but after 6 months decreased to 98% (3225 mAh) so far battery life on the s9+ is just a little bit better than the notr but I'm pissed to find out the estimated capacity is only 3300 mah as it was one of the reasons I jumped from the note (3300 mah) to the s9+ (3500 mah)

6 cycles, 3302 mah. Snapdragon model.

So they did this with S8/S8+ as well?

no I have an s8 and the estimated capacity is 100% after 3 months!

so is this accurate to base on if we got good battery in our new phones?

I was looking at the s9+ BOM compared to the s8+ and Note 8, what I found interesting is that battery is 37.5% more expensive on the S9+ ($5.5) compared to the s8+ or Note 8 ($4). When they announced the s8+ they said it would degrade only 5% vs 20% of other batteries after certain use but did they mention any difference with the s9+ why would it be 37.5% more expensive?

battery 3800 not 4000?!

There is one application that estimates you battery health and size after a charging session, it keeps telling me that my phone is 3799 aka 3800 not 4000, can any of double-check? It's called accubattery on the playstore.. Is there any other app that can do that so I can recheck
I guess some models were released with lower capacity batteries which means you're doomed.

It says 4000 on the box, im just worried it's a bad battery
You're probably fine, have you tried another app to check? I'm using aida64 and it reports 3900 mAh
Batteries are not a precisely defined size. It's not like they are machined out of some material to an exact size. They are a bunch of messy chemicals and there will always be some variation in capacity.
It's up to the manufacturer's honesty whether they specify the minimum or average or maximum capacity.

Maybe yeah, but 200 mah is too much, when my s7 edge was 3680, even more than advertised
So you guys don't think it's a defect or something? Worth checking out?
I doubt it's accurate. On my current phone which is over three years old it says the capacity is still 3000 mah like the day I bought it. That would be an incredible feat but very doubtful.
Your battery is fine, don't worry about it.
If it shows 3400 mAh in a few months, well...
Thank you guys, I'll keep it and keep checking every month, if its getting worse then I can always check with my warranty provider

Same here. At the moment accubattery is reading my battery at 3741mah 94% life.

I use the same app for all my Android devices (I set a charging limit alarm to 80%). In the first couple of days I had my Mate 9 Accubattery was reporting 3920 mAh. I uninstalled and reinstalled it thinking there was something wrong. Then the next time I installed it it was reporting lower capacity of 38xx mAh. So I just ignored it and let it run. A few more days go by i randomly checked it and now its showing 4002 mAh 100% health. So I think it has a break in or calibration period for it to properly detect the actual size of the battery

There is a reason for that and the explanation can be found in the app itself. Some manufacturers report a lower size battery than the actual battery size. Therefore you see the health is still at 100% although it already has degraded.
My battery shows 3850 and 100% life battery since the first day I got the phone. It last 2.5 days with medium/high usage. it took me a while to optimize all the apps I have installed in the phone tho.
in my understanding the number that gets reported to the app isnt the real capacity but the capacity keyed in to the Kernal file. Nothing to worry about guys.
Mine is still only takes around 3750mah worth of charge using Accubattery.
I remember some blurb that battery manufacturers have some %10 or so leeway in what the battery actually delivers versus what's written on it.. I wouldn't worry about it; what's 200 mAH between friends?
I did speak with the Huawei support center regarding my battery only taking around 3700mah charge and they informed me that it's normal and it's for backup.
That does not make a lot of sense but I do understand there are manufacturing tolerances. The battery in the mate 9 is rated for 3900mah with a typical capacity of 4000mah. So going from 3900 to 3722 on my last benchmark charge isn't to bad.

Mi4c Real Capacity of the Battery

Hi to all,
I just wanted to make a debate about the real capacity of our phones batteries.
That's because I found an app that allows us to measure the real capacity and I found a quite astonishing result: it seems like my battery has the same behaviour as a 2200mAh ones!
In fact, with all connection active (Bluetooth, Wifi, LTE, synchronization..) I barely reach 3h of SOT daily.
I used 3C toolbox (https://play.google.com/store/apps/details?id=ccc71.at.free) using the instructions in this answer (https://android.stackexchange.com/q...ity-of-a-battery-in-mah-received-fake-battery in "How to measure actual capacity using 3C Toolbox").
Also if you can advise different apps and methods to do this, I would be very happy.
Thanks to all!
The real battery capacity is the advertised one. 3000-3080mAh.
Xiaomi uses lower binned batteries which degrade a bit faster over time. An app can't measure the real battery capacity or estimate it accurately. The SOC we have is power hungry and inefficient, that's why it's so hot too.
I think it's 1500 mah or something like that. I get only 2 or 2.5 hours screen on time. The results has been never changed which i've tried several roms.

Well, the app don't measure the battery capacity, but how much current flows in when it's charging.
So you're saying that the main problem is the age of the battery..
Do you think that changing battery may improve the result?
3h sot is normal, when used from morning till evening. When used continually, I get 5-6h sot. An app cannot accurately measure battery capacity. This phone, like many others, is built to last a day with moderate usage...

Hello, this is a very interesting topic, so I decided to check the real capacity of my Mi4c's battery with one of these. When the phone turned off at 0% I recharged it to 100%, while still off, with the following result: 1.76Ah @ 8.8V as I was using a QC2 charger. Let's translate it to the battery's 3.8V assuming 80% charging circuit conversion efficiency:
Code:
((8.8 * 1.76) / 3.8) * 0.8 = 3.2Ah
My battery is 6 months old and seems to be slightly better than specified.
If you use a 5V non-QC charger try one of these to measure it and assume higher 90% efficiency. Android battery apps are useless, please check it out with a hardware meter...
:highfive:
I'm already running third battery with my mi4c, all three tested with a similar hardware meter:
1. original battery, but already with signs of being worn out (shutdowns, sudden voltage drops) ~12Wh, not tested as being new
2. aliexpress replacement (getting worn out after 3months of use) ~13Wh
3. some battery I've got at local online shop that seller claims to be original (not 100% sure, but dimensions and weight match the original one) - sligthly over 14Wh
4. -another mi4c, as it was brand new- just over 14Wh from empty to max; surely the battery is in good condition as the one can reach 6h SoT
and I've tried different chargers (QC,non-QC) and no go - no way to see 15Wh or more being transmitted in one charge on both mi4c's I've got at home

And our battery behavior is a lot better.
Should I consider the values from /sys/class/power_supply/bms/ valid?
charge_full = 1983000
charge_full_design = 3071000
Does that mean that my battery capacity is now only ~2000 mAh?
EDIT:
charge_now_raw reports 2952776 when my battery level is 98%. So something is definitely wrong there.

Your results are fine but you're not accounting for the efficiency of charging which also decreases with higher...
charger's voltage
meter's internal resistance
connecting cable and contacts resistance
My 15.7Wh on the meter is actually around 15.7*0.8=12.5Wh on the battery.

Some of them are definitively valid, others depend on type/firmware version of the control chip integrated in your battery. Here are mine:
Code:
POWER_SUPPLY_NAME=bms
POWER_SUPPLY_CAPACITY=51
POWER_SUPPLY_CAPACITY_RAW=5143
POWER_SUPPLY_CURRENT_NOW=432278
POWER_SUPPLY_VOLTAGE_NOW=3837410
POWER_SUPPLY_VOLTAGE_OCV=3874031
POWER_SUPPLY_VOLTAGE_MAX_DESIGN=4400000
POWER_SUPPLY_CHARGE_NOW=0
POWER_SUPPLY_CHARGE_NOW_RAW=1481002
POWER_SUPPLY_CHARGE_NOW_ERROR=98504
POWER_SUPPLY_CHARGE_FULL=3101000
POWER_SUPPLY_CHARGE_FULL_DESIGN=3071000
POWER_SUPPLY_TEMP=285
POWER_SUPPLY_TEMP_COOL=0
POWER_SUPPLY_TEMP_WARM=450
POWER_SUPPLY_RESISTANCE=110778
POWER_SUPPLY_RESISTANCE_ID=50306
POWER_SUPPLY_BATTERY_TYPE=x11_atl
POWER_SUPPLY_UPDATE_NOW=0
POWER_SUPPLY_ESR_COUNT=64
POWER_SUPPLY_VOLTAGE_MIN=1
POWER_SUPPLY_CYCLE_COUNT=0
It was measured with the power gauge at around 55%. My CYCLE_COUNT is surely higher than 0 after 6 months of use, and your CYCLE_COUNT=20430 is simply impossible
I'd more believe your charge_now_raw = 2952776 than charge_full = 1983000.
Incidentally, the simplest way to get these stats is from TWRP in ADB:
Code:
adb shell cat /sys/class/power_supply/bms/* > bms.txt
Hey guys, long time no see
I did not see the thread, but i went on with my speculations on the same matter.
I bought this from amazon https://www.amazon.it/gp/product/B00NPVZHAO/ because i wanted to test my day-one mi4c battery.
It has roughly one year and a half.
Well...from 0 to 100% it gets a whopping 1617 mAh (see the attachment).
I was disappointed, but hey, maybe i had a degraded battery to start with, and since i never measured before i went on to buy a new original one.
Well, yesterday it arrived. changed it, discharged to 0%, charged to 100%.
Okay, it's only the first cycle, but...
1800 mAh
I guess advertised capacity is a long way from the real one?
After all, if this is correct my old battery degraded by 10% in 18 months...and that's realistic.
Please tell me i'm wrong.
I bought it for this job and I wait. But unfortunately there is not much hope
Nexus 5x has very similar specs and very similar SOT. Also, the original qc charger is supposed to charge using 5v,9v and 12v, not only 5v. What does that say about your research? Either both manufacturers lie, or you're doing something wrong.
I get anywhere from typical 3h(usage from morning till night) to 6h(continuous movie watching using streaming). For the record...

Code:
((8.91 * 1.617) / 3.8) * 0.8 = 3.03Ah
Which is exactly as advertised by the manufacturer.
No need to change batteries, your SOT is low because of the awful apps you use. For example, did you know that "uninstalling Facebook app saves up to 20% of Android battery life"? You can still use FB and its notifications without the app - read the article.

Thanks @k23m, i felt like a student again but after reviewing your formula you are right.
I though the tool's mAh measurement were already adjusted for the battery's voltage, but as you showed we still need to do some math.
I guess that i didn't need a new battery after all, but now that i have one it's certainly better!
I don't have issues with SoT, i do 5-6h on TS CM13 (i stay on marshmallow for xposed) but i just wanted to test battery degradation.
I will still post new battery results after a few cycles.

ebay battery seller with 20k feedback 99%+ positive.
I never saw the oem parts of xiaomi on the internet but I dont know i hope this original.

I replaced the battery 3 times, still I only can use 2500-2600 mAh Capacity - help

Hello,
I replaced my old battery because it lost its 30% capacity. Then I bought 2 times original Samsung Battery and 1 time a super expensive battery from Germany.
Everytime when I test it, I use only 2500-2600 mAh capacity of my Galaxy S7.
I did calibrate my battery, cleaned the gauge multiple times, reset it. It didn't help.
I just notice that my phone charge only until 4.825 V. Do you have any idee?
Maybe a problem with the apps not the battery itself?
Those apps are not 100% accurate anyway, they cannot be as you never run your battery to 0% while the app is running
I used 3 methodes to measure it. I dont think so. How is your phones fg_full_voltage value?

What is more likely? That the apps methods are not accurate, or 3 new batteries all have 2500-2600 mAh capacity?
The apps method are known to be inaccurate so you can already forget about those results
Where is the location of that file?
There is a code you can enter to reset battery stats too
dial: *#0228#
Press Quick Start
Connect Charger so phone is charging
Turn Off the phone and leave off until battery is charged to 100%
Power on phone
Battery stats should be recalibrated
I did that already, hmm the location is /sys/class/power_supply/battery/fg_full_voltage and in the same folder 2*fg_fullcapnom shows the capacity of your battery.
You can be right with the inaccurate apps, but the apps showed me the real value with a lenovo zuk z2 and galaxz s8.That's why I'm worried

eBay only sell fakes fakes and more fakes, Amazon probably too, unless you bought an original Samsung battery from Samsung there is a high chance that all those batteries are not as high capacity as advertised
My battery life is terrible with my S7 flat, so I took my phone to the Samsung Official workshop, I thought that a brand new battery will fix the problem, the technician made some tests and he tell me that although my battery was fine with 80% wearing but my battery drain issue is caused by a faulty board.

I'm pretty sure you bought the fakes ones. Try to buy your 4th battery from a Samsung service center!
My Third is not a fake one, it has 24m Warranty and is Made in German. The problem is with phone and OS. Nougat won't let you use your all battery capacity. If you dont believe me, use accubattery you will get max. 90%.

Is OP6 battery really 3300...?

Hi, just wanted to ask if someone else beside me and my friend got a 3000mAh battery (According to accubattery) after a couple of months, the same happened to another friend of mine with a OnePlus 6T, 3450mAh instead of 3700mAh.
Screenshots attached.
Accubattery is insanely inaccurate, and takes an estimated guess based on charging cycles. Long story short, the app is garbage and people should stop putting faith in it.

I've already tried to search for a this app, and I found a thread in the OnePlus 5T section where a USB multimeter in, at least, two cases, has shown the same result as Accubattery.
Anyway thanks for the answer, need to find why battery sucks su much on both my friend phone and mine.

I experience the exact same issue on my oneplus 6. The accubattery app shows my battery health as 3,046 mAh and design capacity as 3,300 mAh. It has been this way since the day I got the phone (around one month back). I am pretty bummed that oneplus sent me a phone that had only 90% battery life to start with. Is that a problem with the battery or is that a problem with the way the accubattery app reads the results?

It has been this way since the day I got the phone (around one month back). I am pretty bummed that oneplus sent me a phone that had only 90% battery life to start with. Is that a problem with the battery or is that a problem with the way the accubattery app reads the results?

Seriously? As stated before it is a calculated capacity. It measures how much goes in and out. While the battery is shipped as 3300 mAh the app can very well vary as it is only roughly calculated and the full capacity is very theoretical as the voltage decreases and is never zero.
You start with 4.35 V = 100 % and end at maybe 3.2 V = 0 %. So you have energy left after your phone as shut down. That's why you get a battery low screen even if your phone has shut itself down. It is not a design flaw and it is not scam.
Also don't forget that different components use different voltages. Transforming them results in wasted energy. Like a power bank that has 10000 mAh in theory only can charge maybe 7000 mAh while the rest is lost in heat.
thank you !

thank you for your detailed analysis !
It's kind of reassuring because when I bought mine it was second hand and I saw around 3000mah as well! So actually the battery wasn't damaged probably.
It could also be OnePlus which makes the choice to not allow the phone to charge completely so the battery lasts for longer in long term. I Kno Dell does it for example. Then it would be very acceptable. But yeah, maybe it's the app.
Had the same issue with several phones, for example with the S8+, Accubattery showed 97% from day one, after a few weeks it dropped a bit lower still.
The app seems highly inaccurate and I quit using it.

Show your reported battery capacity (Exynos)

As I have not found a list of user reported batter capacity I thought, let's create some insight so here we go!
Accubattery shows on my 1 week old Exynos ultra battery only has 4041 mAh capacity
What about yours?
You can't figure out the capacity of a battery after two partial charges.
Why do you need these figures? My sm-n9860 shows me the ~20 hours TTL after the full charge (stats are based on the heavy browser's usage) - TTL is the only useful indicator I guess.
I know that 2 cycles is not enough, that's not why I started this thread.
It is interesting to track capacity degradation over time. If everybody reports there figures every now and then, providing insights on that could help people identify battery issues. Although with all the different measuring app outcomes it will not be an exact sciense but an approximation.

Here you go if it makes you happy I don't mind participating.
Day 4 of ownership. And one day after a factory reset.
The Note 20Ultra's battery has a kernel charge limit of 4060 mAh -100%. So it's not about 4500 mAh only 4370mAh with limitation. I will never understand these huge differences recorded on Samsung batteries between the declared minimum value and the value recorded on charging.

I see that you partially charge your phone 40-80%.
I don't know if this partial charge will really extend your battery life. At Samsung I have seen over time that the situation is upside down and the charging counter is misled from where and sometimes a strong drain. If this partial upload by Samsung were supported by the software, then it would be a good thing otherwise I don't see much. As with Apple, Sony, Oppo ..

I always partially charge my phone approx 40-80 sometimes higher l, sometimes lower.
Samsung batteries seem to have a some sort of reserved area that doesn't get used until a certain degration is reached. That's my hunch.
PS I got an SD n20u now, no different to exynos ?
From my experience in the past with these battery monitoring apps the battery health measurement is pretty innacurate. When I first got my 20 Ultra it said the battery was at 94 percent health which was definitely wrong.
Same in s20 and s20+.... the charge stoped in 3600 and 4076 respectively... great work samsung
Mine says 4370, is there a difference between exynos and snapdragon?

Then why did you change it and didn't stay with exynos? It's much better snapdragon on gsm, battery ...?

In battery capacity not. But in terms of speed exynos is slower and uses more power. Also more heat...

Because it was faulty. Random reboots even in safe mode.
Edit. The SD one is also defective, green tint. Samsung really has gone down the poop shoot quality wise lately.

No problem for me. The best phone so far. I think I'll keep it for two years, especially since Samsung decided to cancel the Note series.

I very much doubt this model will be remembered favorably in the future . it'll probably be the note 3, 4, 8,9 and 10 that sticks with most of the fan base.
whats your charge cycle ?

38 cycles and 99% health by accubattery.PhoneInfo
says something else I suspect depending on the kernel limitation,93,6% health.
The best way to extend your battery life is to switch your phone off at night. Lets estimate a 33% longer life assuming one sleeps 8 hours a day. 33% for free!
In the mean time my estimated capacity is up to 4370mAh

I installed phone nfo since day one and the charge cycle counter seems accurate unlike the health .
