Hello,
I'd like to show you my private comments and tests on the battery for this great phone.
I tested many replacement battery for Nokia 8.
A lot of people have trouble buying a new battery with sufficient capacity.
I checked some batteries. Original is identified as HE328 -3030mah -nominal capacity.
Original Battery look like this:

Fake Battery available on internet looks like this:
Many retailers report that the batteries come from the manufacturer. Unfortunately, it's not true I checked 3-4 batteries like this in picture. All batteries had almost 50% real capacity.
My almost 3-years original he328 battery have best capacity like below:
I've decided to test the battery from aliexpress Wonkegonke
This first charge cycle I am positively surprised at the performance of this battery.
I hope the information will help you fix many phones.
This post will be edited next time. Almost 20hrs usage.
Almost 24hr from last charge. Phone used normally without any issues
I end day like with my Nokia 8 with original HE328 battery.
Ok i want to show you battery health "WonkeGonke" from aliexpress after 4 sessions.
additionally, I checked battery capacity via ADB in PC:
Real capacity is 2829 Mah 91% from 3090 Mah. This is good capacity i think
Thank You
Thx man :good:... nice to know that when my battery dies I wouldn't have to throw away my beloved Nokia 8
quick question... what app r u using to measure the capacity?
This app is named AccuBattery is installed from Google Play. Nokia 8 is one of phones which can measure battery capacity almost accurately
Uh, "Genuine" looking fake batteries are in action as always ?. I learned what means genuine battery a couple of years ago. Most of them haven't the nominal capacity as it supposed. Beside this fact, they haven't a proper NTC resistor (which is temperature sensor). I want to ask a question even i know the answer (maybe it makes me surprised). Could you check battery temperature with different scenarios (daily and heavy) via AIDA64 and post the screenshots here?
I can check that, although as I remember, one of these batteries displayed the temperature probably correctly.

Design capacity seems to be 3500 so at 2800 seems to be at 80%? The question if it will stay there. I cannot find the link in Aliexpress by the way
For better marketing, the manufacturer gives overstated parameters.

can confirm is the battery temp sensor always stays at a fixed temp or it is actually working?
i bought 3 times the battery my Nokia 8. All of them only have around 1400~1500mAh and the temp sensor always showing 27deg.
Further testing found out all the fake batteries can't do Quick Charge at 7v,9v, or 12v. It only can do 5v 3A charging.

I experienced this problem on my old Zenfone 2. All batteries i bought were fake. They all had same capacity (2400mah) and fixed temperature. It was really hard to decide which is fake/genuine.
After several years, my NB1's battery is getting older and probably I'm gonna replace the battery in a year. So it would happen again and it's good to know which one is fake. Can you post the links you bought from or images of the battery? It would be really appreciated and helpful for us?.

I bought from Shopee Malaysia. I see most of the seller posted the item image is different than actual product received. From the picture you can see the bottom of the fake one is different. And the fake capacity battery is half the thickness of the original battery. Anyway, I ordered the WONKEGONKE brand from their shop in AliExpress. Will try out and update here.

My fake batteries always quick charged. When I'm at home I will check how wonkegonke behaves.
Wonkegonke is one battery what working better than any other fake. Please provide accubattery stats.

Much thanks brother for all you work and information. So here's is my story, same problem, some said software issue, Google Services and its fellows, OTA, even holy motherboard.
But after wondering and desperately hunting internet, I finally found the culprit and replaced battery from a local store, it was exactly like you posted and that old one on the device, again after around 7 months, now I'm having same issues, so was planning to go visit official nokia care and get replaced despite the cost, but just moment ago, saw a comment posted by an indian user having same issue even after replacement from a Nokia Care Center.
So i want to consider this time, is that one from aliexpress that good ? and working fine till date ?

Introduction
The urgent need for a spare battery for my device, I felt at time of a journey to Portugal in May this year. The trip was an independent, we have decided to prepare it without use of tour agencies. All navigation in Lisbon, searching for information on attractions, and, of course, simply communications was tied to a smartphone. It soon became clear that, in this mode, my Galaxy S barely survive until lunch. In this situation, I often turn off the phone, to somehow leave it live to the evening.
Arriving home, I tried to find out why the battery goes out so quickly. In addition to attempts to optimize the software side, I began to collect statistics on battery with Battery Monitor Widget. In the end, it turned out that the real capacity of the battery instead of the regular 1500 mAh (declared by Samsung) was a little more than 1300 mAh, ie significantly lower than the nominal.

}
Conclusions for myself:
Install some phone battery saver.
Buy a spare battery.
Testing alternative battery
I did not want to buy the original battery. Its capacity could differ from declared again. I've started to read the forums, blogs, etc. I came across for a few articles, which described the alternative batteries for smartphones HTC. Both of review were about battery manufacturing company Mugen Power. I learned that there is some likelihood that the manufacturer can provide me the battery for my tests. I wrote a letter to the Mugen Power. The letter said that I am a PhD in power electronics (which is true), that I have a desire to test the battery for Samsung Galaxy S. Very soon I received a positive response. By following a few formalities and waiting a little longer than 3 weeks, I've received a packet with a battery for testing.
The geometrical dimensions of the Mugen's battery is almost the same as in original. Myugen's battery was a little thicker, but it fits in the smartphone without a problem.
In the manual for the battery, manufacturer especially requested a "training" of battery. I should "Train" it by running 5 or 4 full charge / discharge cycles. In addition, it was clarified that the charge cycle should be not less than 8-12 hours (even if the phone tells you that the battery is fully charged in less time).
I followed all of the instructions. Along the way, I do check readings Battery Monitor Widget. In the first cycle capacity was about 1200 mAh, and at the fifth it barely got over 1400 mAh. This, of course, more than have old original battery but substantially less than the stated 1600 mAh. I am wary, but decided to give it a chance for rehabilitation and went with it to vacation .
10 additional days that I spent in vacation, led to a very positive effect on the battery. Battery even exceeded its declared capacity and was equal to 1626 mAh, which is about 2% bigger from the nominal.
Indications of Battery Monitor Widget is already good, but most importantly to experience an increase in battery capacity. Indeed, smartphone living time has increased so much that night of charging it was enough for the whole day of living. Thus I can conclude that living time was increased nearly in 2 times. For the entire time of vacation I never change a battery to the old one. I always had time to get back to the hotel in the evening and put the phone on charge.
A few words about the mode of using the phone on vacation. Wi-Fi and mobile internet enabled constantly, GPS navigation for at least 2 hours a day, for about 15 minutes reading the mail, 30-40 minutes of surfing the internet, talk no more than 1 hour a day.
If less of navigation, the charge lasts for at least 1.5 days.
Conclusions
Measured capacity of the alternative battery even exceeded the nominal and was 1626 mAh.
Given the fact that the actual time of use of alternative (new) battery has almost 2 times bigger, I suppose, that the real capacity of the original (old) battery is less than 1300 mAh. For myself, I decided that in this case purchase of the original battery would not good idea, even if it is cheaper than alternatives.
In spite of everything, I highly recommend you to have a spare battery along with you on the trip.
I think that this review will be useful to many people, as the Samsung Galaxy S, despite his respectable age, is still quite popular smartphone. I will be happy to answer questions and clarify details.
PS: Name of the tested battery is "Mugen Power 1600mAh Extended Battery for Samsung GalaxyS GT-i9000 / Epic 4G / Vibrant / Captivate
[HLI-Si9000SL ]".
Mugen Power company also produces "unformatted" battery for Samsung Galaxy S with capacity 3200 mAh. I did not want to thicken up the phone, so this option is not even considered. Decide for yourself.

Yes, exactly! This is an official site of Mugen Power.
I've found this battery on it.
1. Have you bought full version of Battery Monitor Widget?
2. When training battery, do you really need to charge for 8-12 hours, because batteries have overcharge protection?

I use free version of Battery Monitor Widget. I simply cut out advertising banner from a screenshot.
In accompanying document exists a direct instruction to charge battery during 8-12 hours for training. See attachment below.
So i got a Note 4 recently and immediately went for the Mugen Power 6640 mah extended battery. I just missed the FedEx truck today, hopefully i can swing by there tomorrow or else i will have to wait til monday. The battery life on the Note 4 is pretty good, coming from my HTC One M7, and the quick charge is VERY nice, but i really think i need this extended battery.
I will be posting some results from my experience with pictures of course in the coming days, as soon as i get my hands on the thing that is.
Here's what i am getting.

Yes that's the same battery. I see there's quite a few pages on that thread, did anyone actually post test results, i went through the last few pages and didn't see much. I did notice someone said the case i bought should fit, (fingers crossed)
Here is a previous review i did, i will post something similar, focusing on the test results for battery life mainly.

How have you found the battery life? Reason I'm asking is because I've tried the Anker 6440 extended battery and unless I didn't "condition" it properly I didn't see much of a better battery life than stock battery. Why I'm returning it.
For me gonna try the cheap battery cases like the knock off Mophie types from eBay and Amazon.
Last night I tried to kill it from a full charge. I got over almost 7.5 hours of screen on time mostly just running cpu+gpu stability test within full brightness, GPS, wifi, Bluetooth enabled with sync going every 15 minutes.
That's pretty good. For me I don't find much difference so I'm returning mine but glad you're getting better results than me. I also have the zerolemon 10,000 mAh beast but way too bulky for normal use.
Hopefully my cheap power bank battery cases come soon and I can try it out. For $17 shipped I figure not much to lose
Also you probably get what you pay for there. The Mugen is a $90 product, the Anker is a $30 product. You can't possibly think they are the same quality even though they are both rated the same capacity.

Kinda like i was saying before, with lithium ion stuff and also varying types of battery packs chemistry, usually you get what you pay for. I've used Mugen products on my Tmobile G2, HTC Evo 3d, and my One m7, all performed the same for the 2 years i had the phone, the cheap ones don't last the length of the contract.

That's true I guess but I've tried both Anker and Hyperion extended batteries and they're supposed to be reputable companies. And both don't seem to last as long as their advertised battery sizes. For me I'm not willing to pay $90 to get a few extra on screen hours (I'm averaging about 6 hrs OST with stock battery)

I'm sure I could get a lot of screen on time with normal use like power saver with auto brightness. Remember those numbers I got with screen on are maximum power consumption, max screen brightness, wifi, GPS, Bluetooth with a benchmark running both cpu and gpu at the same time. I guess it would be useful to see how long the stock battery does under the same conditions to get the big picture. 7.5 hours under those conditions has to translate to much more with power saver reducing cpu usage and auto brightness. I don't need full cpu speed unless I'm playing games.
thanx for sharing
I am still in the process of conditioning the battery. It stays at like 1% for 3 hours of full brightness screen time on the stabilty test cpu/gpu app. It's very good battery life so far. Will report back when i get everything together. Heres a couple teasers.

Hi, did anyone try 1100 mah battery for Huawei Watch 2? I found it on aliexpress, stock battery is 420mAh and it's not enough for a normal use. 1100 mAh should be better but i'm scared it can burn or damage the watch? Anyone has been more brave than me?
Well, nobody answered, but I can tell you it's 100% scam.
Physically it's impossible to build such small battery with such capacity.
It's interesting that this seller has sold 39. But they sell HW1 and HW2 1400mah and 1100mah respectively. Their batteries are a lot more expensive then the regular 420mah batteries. SO it does make me wonder if these are higher capacity batteries.
If there is room for a slightly thicker and bigger battery than the original then it is possible to archive a higher capacity. Though 1100mah seems pretty ridiculous I would be curious to know what the true capacity is.

I ordered it, will test
I ordered it too and it arrived yesterday.
I installed the battery but I broke one of the plastic luggs off the watch that allow the strap to clip in so all my testing so far is in "off wrist-mode" which disable's the AMOLED hafter a period off time. I am making this clear as my watch is showing me i am likely to get 3-4 days of usage. Previously it was 1-1.5 days. This all made me very excited. However I ran some debugging tests on ADB, specifically:
adb shell
dumpsys batterystats | grep "Capacity:"
Estimated power use (mAh):
Capacity: 410, Computed drain: 114, actual drain: 65.6-69.7

It's not reassuring to see the capacity listed as 410mah. I assume the watch reads the capacity from the battery itself as opposed to capacity being hardcoded in the rom/os. I suspect because it's a new battery that the health / capacity it much better than the older (4yr older) battery which is replaced. But also because the watch is "off-wrist" I am going to see better performance.
As for the second command above I am little unsure how to interpret it. i thought maybe these were reference to total and current mah
POWER_SUPPLY_CHARGE_FULL=408
POWER_SUPPLY_CHARGE_NOW=342

My first test I left it off my wrist and it lasted 4 days. But I think when it's off wrist it goes into power saving mode because it doesn't need to detect heart-rate (if enabled) however I still felt 4 days was an improvement.
But then I left the watch battery flat for 2 months. Fixed the lugged and started wearing the watch again. The last 2 charges have lasted about 2 days. Which is similar to what I was getting with the stock battery.
I am unsure if leaving the battery flat for 2 months has done any damage or change to the capacity. But since it was a new healthy battery I imagine it hasn't. Perhaps I need to leave the watch off wrist again and see if I get 4 days still.
I guess results are still inconclusive at this time.
Please keep us posted with the testing.
Double the battery capacity would be the best improvement.
Thanks for sharing!

I side loaded accubattery which calculates the mAh drain vs percentage of battery added whilst charging. I have only run it down once but the results were better. 481 vs 410. Still way off 1100mAh but I'll see how it goes the next few drains.

^Spot on.
OP, just be glad it's seems within the OEM capacity range...
i have also changed the battery with an standard capacity one, and got the same results. however lost the heart rate monitor :-( and couldn't identify why....
I bought this phone less than a month ago. I bought it new from a reputable store. The battery is advertised as 4500 mAh typical / 4400 mAh min. I quickly noticed that Accubattery is showing a significantly smaller capacity, around 4000 mAh.

(it was showing 4200 at first, then after a full discharge followed by a full charge it dropped to below 4000).
Normally I would chalk this up to inaccurate measurement, however:
The kernel is reporting design capacity of the battery as 3996 mAh. Maybe I'm misunderstanding this output, but it seems to indicate that the phone actually contains a 4000mAh battery, instead of 4500.
Surely a large global brand is not falsely advertising the battery in their phones, right? What is going on here?
You need more sessions on that accubattery app to get accurate details.

If you are so sure about this, then change the battery. For sure that reputable store sold you a phone with a bad battery. Change the battery, it is still covered by warranty.

I'm not sure about it, which is why I'm posting here. I want to understand what are some other possible explanations for this.
The only thing I'm sure of so far is that Dayuser is making **** up.
Same on my 9 pro+ and actually my gut feeling here is that it's indeed not as long-lasting compared to another phone with similar specs and battery capacity. Great phone, but a bit worrying.
Can someone explain the CHARGE_FULL_DESIGN or send a link to a description. My searches didn't give a very clear picture as users of other phones reported sometimes a match, sometimes a mismatch to the advertised capacities. Might it be that these are old, left-over settings from older Android versions, which don't mean anything anymore?

@Bernie_W thanks for replying.
I actually found a display unit in a store, and it showed a correct value (4436 mAh): https://photos.app.goo.gl/jQZjcWyc1rKGoAcx6
As for CHARGE_FULL_DESIGN, it's supposed to show the capacity of a brand new battery, however some batteries don't implement this correctly and just show the same value as CHARGE_FULL (which is the current capacity at full charge). I believe this is the case on this phone, as I noticed this value changing slightly after a full charge.
It's an interface from the Linux kernel,, not strictly Android. The documentation is here: https://www.kernel.org/doc/html/v5.10/power/power_supply_class.html
Anyway, I sent the phone back for warranty, still waiting for response.

Very interesting video, thanks for that. But even, if the phone would show CHARGE_FULL it should be way over 4000 mAh, so there is something wrong in my opinion. And you gave the prove with your video, that it should be higher.
I started to check, as I had the feeling the battery is not lasting enough. And I had a couple of phones over the past with similar battery capacities. So, I landed here and found your valuable report.
Would be great, if you get back your phone to let us know, if this has changed. I would then consider sending mine back, too.

I just received a response. They confirm the issue and they replaced the battery. I'll let you know how it looks when I get back the phone.

Wow, that's interesting news. I actually confronted the service center here in Europe as well. The didn't try to reject or talk me down, feels a bit like they know. Answer was simply, "if you want to return the phone, please contact nearest service center".
May I ask what they confirmed in your case, would possibly help if I connect to a local service center?
They simply said that the authorized service center confirmed the problem, and that they replaced the battery. No extra details.
I just got back the phone, now it says:
POWER_SUPPLY_CHARGE_FULL=4423000
I'll keep an eye on it and let you know if anything interesting happens.

Thanks for your feedback, that's really very kind.
I think I also contact local service center as I still believe the endurance of the battery is not where it should be. Other user reported 20 hours standby and about 9 hours of SoT. They tested with enforced 90Hz and power mode on. Not what I get on my mobile.

Ok, so this is not looking good so far.
After just a couple days, CHARGE_FULL reported by the battery dropped to 4041 mAh.
AccuBattery also shows similar values:
Also, the headphone DAC is busted (or just ****ty). I've had enough of this phone, I'm just gonna return it.

Oh no, sorry to hear that.
Possibly the upcoming update to A13 could bring some improvement, but if the headphone DAC isn't working properly, that would also be a total no-go for me.
I read a post in a German forum, that a user had audio problems when he restored from a backup. After a reset and installing all from scratch, it seemed to work fine.
I think I will wait for A13 update and decide then.
Anyway thanks for all the great information, I wish you better luck with the new device
Figured I'd try replacing the battery, it's been about 3 years and I'm at like 80% health or so.
Does anyone know if any of these are worth trying?

From the ones I've seen the Nohon one has the most and best reviews but I've also read on reddit and other places some comments that they're not that good. Is there any difference or all the same just different brand?
I'm using Nohon ATM. It's fine but not perfect. After 2-3 weeks battery condition dropped to ~90% and its holding this from few months. Other and for sure not genuine. I have replaced my battery because it has under 70% health.

I guess I will try the Nohon as well. The rest are cheap enough as well where I can try them if the Nohon one doesn't work.
My battery is around 80% and it discharges super fast even when not in use, so that's why I'm thinking of replacing it. Thanks
There is one more thing worth mentioning. With Nohon battery charging over 20W is not working.
Oh well, that's not that bad, only 10 less than the warp charger
How do i find out my battery condition?

Battery Guru, accubattery, apps like that. You need to do a few charges and it will tell you after

I ordered the first link back in November (2022 100% Original New Replacement Battery 4000mAh BLP699 For OnePlus 7Pro) and it appears to be OEM. Different manufacturer from my original battery, but so far it seems to be providing the full 4000mAh and dash charging is working fine. Battery manufacture date was October 2022, which is brand spanking new. It also comes with some of the tools required.

I ordered a separate replacement adhesive for the glass back.
So far so good.
How do the batteries you bought hold up? I am currently at 55% original capacity and cannot decide what to buy...

I bought a BLP745 for my 7T Pro from the same AliExpress store as you, my battery was also dated October 2022. I did the swap yesterday and last night was the first charge to 100%. So far two hours have passed since I unplugged and I'm at 97%. With my original battery, I would have been at around 85% by now. I'm using accubattery to see what the capacity of the new battery is, I'll report back in a week or so. I have yet to try warp charge also, never really used it previously to be honest. I usually just let my phone slow charge over night for the past three years.

In the last month and a half, very solid. Accubattery is reporting 104% of design capacity.

Nice. Make sure you do a few full drain to 0% and recharge cycles to calibrate. I had some shutoffs at 20% before I did the full cycle calibrations

Not sure. I'm not on OOS
Appreciate the information shared here. I'm pretty sure that I need to do this for my 7 Pro soon.
The Ali Express site is showing estimated delivery of July 15 (I'm in the NYC area). Has anyone found a reliable source for these batteries with faster delivery to the US?

A couple weeks with that one and it works like a champ. Hopefully it will stay that way
