Hi everyone,
does anybody know if the Moto Z2 force also has the same battery issue as stated in this thread for the Moto Z? https://forum.xda-developers.com/moto-z/help/issue-2-crazy-battery-behaviours-t3680766
Could somebody check if this batt_health binary is also excluded from running on unlocked bootloaders on our device or if it's even existing?
I definitely had the worsening capacity problem and the inability to boot phone under 30% charge problem on my Moto Z.
Kind regards
Me too (on old Griffin).
I arrived to be unable to power on up to 50% of battery (and Accubattery reported a capacity as low as 900mAh ) except that on bootloader mode...
And when I left it to an assistance center to change battery... they destroyed my screen...
I hope the quality on Nash would be better... (battery are different anyway...).
I will check into if that is working or not, currently estimated battery mAh is near correct...
Edit: XDA image derp: will show soon. Accubattery estimates near 2600 mAh (2592.2)
Edit 2: yes, it's there and populated. System/bin/batt_health

On mine are a bit higher: about 2630-2650 mAh with wireless charging by Incipio Mod and about 2710-2750 mAh with a (good) wired & "not-so-fast" charger...
Since of my experiences I think your lower values are because of stock charger doing fast charging...

That was USB charging. I left it on my Linux box for the day, so it was slow charging. Below is overnight fast charger estimate.

Well... one single charge with only 33% charged is not so significative (on Z2 partial charging often reports BIG battery estimates... I've just done one of about 25% which reports over 4,000 mAh... :laugh: )
Go with at least a week of various recharge of at least 65-75% to have significative results ...
When my old Z begun to have a dead battery I was able to charge up to 1,500 mAh with a slow charger BUT less than 1,000 mAh with its fast one...

My phone barely goes under 50% though...
It's better for batteries of this makeup to stay between 50% and 80%. Anything out of that range will drastically affect battery longevity. EG: my VZW M7, I got it pretty much the week it came out. Verizon had a BOGO deal, so the wife got one as well. She always drained it to 10% before charging to full. Hers started seeing shorter battery life after about a year when my battery was fine and it finally went out due to the known emmc defect three years later.
I try to make sure my phone is unplugged around 80% just so battery stats reset like they are supposed to after being taken off the charger over 80%.
In essence, charging 65-75% in one cycle hurts your battery if you're looking to keep the device for awhile since it is a pain in the ass to swap batteries now.
I know, but I was only talking about statistics point of view...
In fact I prefer slow charge whenever is possible and I follow Accubattery hints as more as possible...
I purchased my 5t about 4 weeks ago and the stats in AccuBattery are now showing my capacity at 2930 mah and the health at 89%. If accurate, these are somewhat concerning considering how new the phone is. Anyone else seeing similar stats? I ran AccuBattery on my Nexus 6p and it always seems pretty accurate.
That's the same capacity I get on my phone with AccuBattery. Other people on the OnePlus forums also had the same results so I think that it is probably normal.
I don't trust that application any more (even if I bought it 2 days ago). So i purchased my phone 4 days ago and after the second charge it says 89%.... Many battery applications are useless on the Play Store.
It is a little wonky on certain phones sometimes. Have you done several charge and discharge cycles? I know it definitely won't be too accurate until you run it a few times. Since you said you used it on your 6P though, I'm guessing you know this already. As long as battery life is still good, I guess I wouldn't worry too much.
I run Accubattery on my mine, it says 92% after a couple of weeks. Battery lasts for a full day of heavy use, and then some.
I also ran it on my 2 year old Moto X Style, and it said 51% - and I felt it was telling the truth, since I got about 2hrs SOT from it if i was lucky!
Same for me, showing about ~3000 mAh from the beginning.
It's also showing ~107% on a Nokia 3 of a friend of mine, so I guess you just can't trust the app on that perspective.
lol, guys
ok now, several factors to consider before you jump to conclusions (ive been using accubattery for several months now with great results):
1) your sample size is waaay too small. every scientist/engineer/mathematician, etc out there will tell you that u cant jump to a conclusion based on just two samples. give it some time, use the app regularly for several weeks and only THEN can you make assumptions about the accuracy of the collected data.
2) ive noticed that the final capacity reading is more accurate, the closer a charge cycle is to 100%. which makes sense if you think about current quick charging technologies: they provide high amperage at steady voltage at first up to like 75-85%, then they switch more and more to trickle charge with low amperage. advantages: fill up the battery quickly, but without putting too much wear onto it.
thus: if you just do a quick charge cycle, say from 30-50% then the slope steepness is way higher, thus the calculated capacity will differ. so there is a dilemma: either do large charging cycles with higher wear on the battery, but more accurate capacity data in the end, or do smaller charging cycles with inaccurate data but less wear on the battery.
3) when charging to 100%, dont unplug the phone when it reads 100%! rather check the current charging amperage in accubattery. only when that drops to zero (or -1 mA in my case) is the battery fully charged and ull get a more accurate capacity reading than when stopping the charge when 100% is reached. if you unplug it too early, the capacity calculation will be on the low side
hope this helps!
cheers

Yup, am scientist, can confirm
Same thing happened to me, even after using AccuBattery for a couple of weeks (and thus collecting more than a couple of samples, both Dash charge and "normal") it still showed 89% battery health at around 2940 mAh. Got my phone one month ago.
I don't think there's any problem with the battery itself, especially as it's not just me having this problem.
Maybe the battery is 3000mah and they are lying about it ???

I'd say 30% of the times 10 to 100%
40% of the times 30/40 to 100%
And the rest just random stuff: 50 to 100, some top ups here and there
This is not scientific data though, that's just what I recall from the couple of weeks I used AccuBattery. I'll try to find a screenshot but I doubt I have any.
I reinstalled it today and from a single 14 to 80% charge it gave me ~2930 mAh and 89% health. I'm on OOS 5.0.2 stable, will try the app for some time and share my results (more scientific this time)
After several weeks of use, the reading is still constant at 86% ~ 2827mAh. Not sure what to think. As previously mentioned the first 5t I purchased and returned for the 128gb version came in at 89% same as @Explyy. Is it possible I have an inferior battery?
hm, there indeed seems to be a pattern emerging with so many different users reporting identical capacity values at 2900-3000 mAh for their new op 5t. two possibilities: either accubattery cannot properly read out and analyze the 5t's battery charge controller. or the battery capacity is indeed around 2900-3000 mAh instead of the advertized 3300. its normal for battery capacities to be around -100 mAh from the official value, but -300 to -400 would be crazy.
guys, just to be sure: did you leave your phones plugged in until the charging rate in accubattery dropped to 0 mA? as i said before, if you unplug the phone once it shows 100% but still charging, the resulting capacity will be less than the actual one.

Yes, I left the phone plugged until the charging current dropped to 0, as I noticed that when it reaches 100 it's still charging at a few mA
On a related note I charged my battery from 10% to 100%, until the mA rate dropped to 0mA. I had the phone hooked up to a USB power meter during this time. The USB meter only read about 2500mAh charged. So since I only charged 90% of the battery I figured it should be around 90% the capacity of the battery, which is 2,970mAh. If I assume the battery is 3000mAh then a 90% charge would be around 2700mAh, closer to my reading. I'm going to run some more charge cycles and see if I get the same results.
Edit: forgot to say that I used a standard 2amp charger, not the dash charger that came with the phone.

Someone who's having accubattery report ~3000 mah should download AIDA64 and look and see what it reports the battery size to be......
I'm just curious, because I've never even looked at the health tab (on THIS phone) until today, since I havent even had my phone for a while month yet. And I also have been getting excellent battery life, so I wasn't concerned about it.
But I looked, kinda by accident at the health tab and saw my estimated capacity is only 96% of what it should be. I've gone through enough charging cycles for their reading to be "accurate" by now, so the data to get the result is there.
I'm just curious, for other people with an S20+, whether it's a SD like mine or the Exynos model, what does your Accubattery estimated capacity read as? Also, how long have you had your phone and how many charge cycles have you done so far? Because there is no way on Earth I could have lost 4% battery in under a month, so either their reading is wrong or Samsung is lying about the battery capacity.

Attaching screenshot for reference.
Mine after 31 sessions says 99%. Some one more technical could help with why yours is low.
Have had the phone for a month now. Exynos version. Had installed accubattery on the first day I believe...
Its a bug I think as I had an s20+ from new and it came out of the box at 17 percent health yet the battery life is phenomenal

Do you charge from 0-100%, every time you charge? Or basically, what are your charging habits?

I don't let the charge run below 25-30% if I can help... I get a screen on time of 6.5 - 7hrs by the time is 25% And 100 - 0 is estimated to last for 9hrs 25mins screen on as per accubattery... I let it charge through the night till 100%, no restrictions there.
Mine is 94% 4218mAh,first phone that I have with this huge difference.I have it for almost one month now..Battery life is great with 6.5-8.5 screen hours..Also strange thing,manufacture date is 5th of March and I get the phone in my hands on 11th of March..Exynos chip.

Yeah that's pretty much what I do, except I don't leave it charging overnight. But for the most part I'll charge to 100% from 30-40%.

I have had mine since March 3rd, SD model, but yeah my battery life is overall amazing...but I have no idea why the estimate is so far off. Because it's no way it went down 4% for me in 1 month. I know it's an estimate only, but it is weird that it's off so much when it should be no less than 99% in the estimate.
Well I dont have much expectations from a 4y old device, but this kinda sudden change is making me curious. I plugged in my phone to the AC mains tomorrow night @ 12 AM @ 5% battery. When I woke up today (@ 7 AM), I just turned off the switch without looking at the charge. When I looked at the charge right now (@ 10 AM), its 77%. My first guess was that some app has drained the 23% battery (I thought it must have charged 100%, anyone will think so if a phone is left to charge for 7 straight hour), but then I had a look at the power statistics (screenshot attached). It just stopped charging after reaching 77%!? Why? It was still plugged in. Anyways, yesterday only I installed Ampere on my phone. Installed because I had doubt that the adapter I had been using for some long time is a fake one. What do you think should be the reason for this type of 'rejecting incoming charge'?
maybe your battery needs replacement.

Hi all!
I have a 2 weeks old S21 FE, and a brand new Samsung original 25W PD adapter + original USB-C to USB-C cable. I am very disappointed with the charging speed, both for wired and wireless charging. I have obviously enabled fast charge & fast wireless charge in settings. The cable, socket and so on is 100% fine. The phone's diagnosis tool reports that all is OK.
WIRED: At 27% battery, estimated 62 minutes left to fully charged. At 55% battery, estimated 45 minutes left to fully charged. At 87% battery, estimated 26 minutes left to fully charged.
WIRELESS, with a 15 W charger+same adapter/cable as above: At 13% battery, estimated 3 hours and 50 minutes(!!) left to fully charged. At 55% battery, estimated 2 hours left to fully charged. At 72% battery, estimated 73 minutes left to fully charged.
Is this really normal?
The Samsung chat person suggested:
1. Charge/discharge the phone 2-3 times after it's new, to "stabilize the battery". I guess I haven't fully charged/discharged (100%/0%) 2-3 times. However, I do not really believe it's gonna work.
2. Reset all settings. I'd rather not - as I will lose some hours of customizing-work. I do not believe this will do it, anyway.
3. "We have a fast charge adapter on the website, it's supposed to work very well". Obviously, and not surprisingly, the ***** haven't read what I wrote.
4. Activate Secure Mode and test again. Did it, doesn't have any effect.
5. And here it comes, the suggestion they really like you to try, but the one that you don't wanna try after customizing and downloading and getting stuff just as you want it: reset to factory settings!!! The favorite customer service way to "help". Obviously, I'd rather not.
So.... Any owners of this phone (or similar)? What's your charging experience? Does it "stabilize" after som charge/discharge?
Thank you so much, I appreciate it. Great phone, apart from charging speed....
Can confirm minutes for wired, same here. Samsung is not the best in case of charging speed
Put in airplane mode or turn off for better speed. Once phone is hot it stops charging completely, they have huge battery protection I guess. It may also limit the charging speed by default
Thank you. It seems strange though, because I have a Samsung A52 phone for work. It is a quite basic phone, but charges incredibly fast. I have tried the A52 supplied charger on the S21 FE, but still the same slow speed... The A52 charges 0-100 in much less than an hour, if I remember correctly.
Disappointed!
Not sure, if that helps, but you might check the app called AMPERE.
I will put the Google Play link below.
Every time I am troubleshooting the charging on any Android device I use this app.
It will basically tell you with what current is consumed by the device in real time.
My S21FE (SD888) can take max 3000 mAh (3 amps).
I would say it's not bad.
It gets anyways too hot to my opinion with the 3 amps , so I am charging only with max 1300 mAh ...
So install the Ampere app on the A52 and also on the S21 FE and let's see if the numbers will be the same with the same power-brick and cable or not ...

So I had a similiar problem here.. My issue was I got a 'moisture is detected in my port' message. Therefore my phone would stop charging.. when the error finally went away Fast/Super fast charging also stopped working.. I took my phone to a Samsung authorised service centre near me ( Closest Samsung was about 2 hrs away) They fixed my phone within 3 days. Replaced my port and the cable between the motherboard and charging block.
Now my phone works 100%
It might be the same issue maybe not. But maybe try different cables and chargers as well.
Otherwise take your phone in for repairs. It should be still under warranty and would cost you nothing.
It seems like the s21fe has a lot of dud phones it looks like

Can confirm this. However after my repair I got over 3000mAh charge.
Before the repair it only did 800mAh
Mine is also faulty. Battery life is terrible and charging became very slow.
Using samsung 25w sfc charger.
Sending it to repair tomorrow.
But i must note that in all cases you must try a factory reset. It can fix a lot of user issues as well as glitches. But in my case the problem is hardware based.

Yes, there is something wrong with this phone. Mine has severe overheating issues.
Try taking it out of the case, in case you use a case. Helps a lot with heat dissipation and this phone needs all the help you can give it during the summer.
