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.

I tried Aida, it gives me 3900 too, but the app im talking about measures it after a charge

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.

[answered] should i claim warranty, because of lower battery capacity?

Hello,
I got my OP6 about a month ago and installed a app wich shows how much capacity the battery really has. Surprisingly it has 9% less than promised, wich means i miss 300 mah. Is it worth to claim warranty because of this? I mean in real scanarios its about 1.5 hrs i miss daily because of this.

The app tries to suggest the capacity...
This is no proof of being true. OP won't accept that.

AccuBattery is not accurate with capacity. It was like that with my OnePlus 5 as well.

I think that just reads os stats and doesn't really.measure it

Likely wrong reading from app,tried a few system info apps,aida64 and devcheck show accurate battery stats for me anyway

I don't fully believe the app, personally. My pixel 2 xl was 109% for the longest time and my op6 goes between 87% and 91% every few days

Yes you are right
No OEM, not only OP ,will accept values from an app. In the end you'll have to pull out your battery and look on the sticker for the values. And then you still have to believe these because I see no chance on how you can measure the real capacity (without spending a lot of money).

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 same issue !

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?

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?

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 .

Can you recommend a new battery?

Accubattery says that my phone battery is at 45% of it's design capacity and really it drains quick. Can you recommend where to purchase a new one? It's a KB2007.
Thanks!

FYI, Accubattery does not accurately measure the supposed design capacity as it doesn't know the 8t has two separate battery cells. So, I believe your capacity should just be double which would be 90. Accubattery reports the same for me. It says like 48 or something which I know for a fact that is not true, so I'm assuming it is only reading from one cell. Try Battery Guru.

I use Aida64 and it accurately reports my battery levels. https://play.google.com/store/apps/details?id=com.finalwire.aida64

That's fine, but can you recommend a place to buy a new battery and what type? My phone would die on me midday if I don't charge it.

I would use a different app to see what is draining your battery, but if it is truly a bad battery, then your best bet is probably eBay to find a new one. Afaik, OnePlus doesn't sell OEM replacement batteries for 8t, but I could be wrong.

Battery Guru says the same as Accubattery: the battery is at less than 50% of it's design capacity. If there isn't a 4500 mAh battery available then I'll send it in to OnePlus for repair.

You may have defective battery. I have no issues with mine + no overheating...and I almost give it no rest whatsoever.
