Note 8 battery fg_asoc and fg_fullcapnom debunked! - Samsung Galaxy Note 8 Guides, News, & Discussion

Fellow Note 8 users, I recently got to replace my 1.5 yr old battery with a new bigger capacity one. 3500mah from Polarcell... Once I get a few charge cycles going with this one I'll post results!
I had 255 charge cycles on the old one and fg_asoc was 92, fullcapnom 2890.
Evidently as I'm a very curious person, I had to test the capacity of the old battery with a high tech hobby charger/discharger from Junsi, the 4010 DUO. As it stands out, fully charging the battery to 4.4V and then doing a deep discharge to 3V netted me 3273mAh. Be aware that this is a way deeper charge/discharge cycle than the phone would ever do. In order to prolong lifespan, Samsung is not using the full capacity of the battery.
Whether there's an algorithm tied to battery aging and fg_asoc, or the battery is actually a bit higher capacity than spec, it remains to be seen. I'll conduct more tests, and keep everybody posted.
Ask away any question the you may have and don't be bummed out it your Galaxy battery is reporting lower capacity from the start. It may not be the case.
Cheers,
Andrei.

I've notice DJI doing the same thing with my Phantom 3 drone batteries whenever I use a hobby-grade charger connected directly to the terminals of the battery itself. I say this is a good design by Samsung if it is as you are suggesting.

Good thinking, I have a ph3 battery lying around wi5h no more than 50 cycles on it. I could measure that too!

You need to remember that your Phantom 3 batteries have a nominal 4.35V per cell as opposed to the usual 4.2, so you would need to factor this in to your hobby grade charger. I have a Hyperion EOS.... model. I've used this to "revive" several phone and laptop cells in the past (once the cell isn't internally damaged).
I don't think one needs to be concerned about fg_asoc or fg_fullcapnom once there isn't too much deep discharging of the cells.

Yes, I'm aware of that. Sometimes I undercharge my ph3 batteries by 0.05v to make them last longer. The 4010 duo is one hell of a charger and I love it!
Back to the note 8 battery, I'm getting spectacular battery life with the new bigger cell and the One UI update. Currently at 60% remaining with 24h of use and 3h of SOT. Stellar!
Cheers!

Just a question, did they reseal the back cover for waterproofing after?

There's no they, I did it myself. Bought some original Tesa double sided tape from ifixit.com and it worked great.

What happens when the battery stops holding a full charge?

So as we all know the more times you recharge a battery they eventually stop being able to hold a full charge. So what happens when say in 1 year the Evo 4g LTE can only hold 70% of a charge? Do you have to send it to HTC to get the battery replaced?
I could see this being a problem on thicker phones where the battery can be deeper in, but on this phone...
http://www.youtube.com/watch?v=LiKpHr8RLBs
The battery is a few screws away I'd be surprised if we don't see a few aftermarket batteries.
It will take way longer than a year to reduce capacity to %70 percent... for example my mac battery that is also lithium ion is 3 years old with 651 load cycles can hold %88 percent of the original capacity.
It will be fine past the two year mark I'd think. My Epic 4G's battery still still as good as new, and my Evo's battery wont be getting charged as much (because it lasts soo much longer).
What is the best way to condition the battery?
I'll just take it to Sprint and have them replace the battery. I have TEP.
I suspect you can take it to Sprint. I haven't had any issues with the battery on any my previous HTC phones. I think you'll have issues with the phone before you have issues with the battery.

Do less full charges. These are lithium batteries and they will last longer if you charge from say, 30%-50% to 100 rather then totally dead to fully charged. All the tutorials you see posted where it says fully charge, then deplete, then charge and deplete, etc don't work. Old alkaline batts used to have a memory and if you didn't do that they would eventually not charge completely. You don't have that issue nowadays.
I agree Bring battery down to a low percentage and recharge it fully.

I asked about batteries at Sprint store (repair store) 2 days ago. They said they are not taking apart the phone. They are going to replace the phone for battery issues.
I had a seidio 3500mah battery in the old evo. After about a year of use, it's capacity dropped to about 70%. The phone went from being recharged every 2 days (with a good 55-60%+ remaining) to about 20-30% remaining after 2 days.
Unless technology has improved in the current batteries, I believe we'll see similar results.

Most of us don't want to pay $60-$90 a year in case a $30 battery goes bad.
It's quite easy to take this phone apart to replace the battery. Just requires a Torx t5 bit and a small jeweler's philips. Really takes less than 5 min to disassemble and swap out the battery.

HTC EVO 4G LTE "Battery"
The battery is a 2,000mAh lithium ion battery degrades if you use it or not, so use it and which has an average of 500 charges, but rarley mentions if it's protected! In previous posts I seen various time of life pertaining to the battery and I just want to say that it all depends if your a power user or not! If the battery is not protected the battery will not be stable and can explode and or recharge up to 1200 cycles and puts out the correct voltage 3.7v protected or not and a LiFePO4 can charge up to 2000 time, but only puts out 3.2 V so I have to say this is strange knowing these devices needs the extra voltage! The only way to go is a Lithium polymer battery which puts out the correct voltage and on average can charge around a 1000 cycles and seems to have less drain on the battery compared to others! Protected batteries conversate back and fourth with the charger to maintain stability, but also counts the amount of cycles which is around 500 cycles for "safety reasons" Everything is marketing! I've been screaming about this video posted above and on the HTC Forum and they've been rejecting the reply's because they obviously want to hide this information! People spend more than this on a mp3 player than what they offer for a trade in and this is the perfect mini tablet/phone! I hope third party companies make batteries for this phone! (((A little off course, but helpful is when your old power tools battery dies "nickel cadmium" you can shock it with twice the voltage by scraping the connection with the appropriate voltage and will burn the crystals off that stops it from charging because this battery has a memory!))) HTC put out a update recently that caused a issue with battery lose for the HTC EVO 4G LTE and it's all over the forum there! funny how this all goes hand in hand! Sorry for the long message, but sometimes helpful...

Li-Po Battery for rezound

hey
i readed that li-po battery is better then normal battery
maybe there a battery that could fit to rezound and work with it ?
https://www.sparkfun.com/products/8483
maybe this could be modded and fit to rezound ?
It's a complicated issue and there's not a clear cut "better" technology. They're both better for different applications. In practice, Li-Po hasn't proven itself to be any better for mobile phone applications than Li-Ion. It's theoretically safer due to the higher resilience to overcharging, and it's able to be made thinner due to the dry electrolyte, but the overall energy density is lower, so you'd get less power out of the same battery size, and they don't last as long as a standard wet electrolyte Li-Ion.
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
Lithium-ion-polymer has not caught on as quickly as some analysts had expected. Its superiority to other systems and low manufacturing costs has not been realized. No improvements in capacity gains are achieved - in fact, the capacity is slightly less than that of the standard lithium-ion battery. Lithium-ion-polymer finds its market niche in wafer-thin geometries, such as batteries for credit cards and other such applications.

I can definitely see why lithium ion is in use more than LiPo, after having learned a lot about LiPo battery technology and high performance electric motors and things like that. With the cheap manufacturing process and corner cutting that goes on with such a scale of mass production like main stream smart phones, planes would be falling out of the sky due to all the smartphones that would be exploding.
I use to argue the other way, that as long as people used them responsibly and didn't jack around with voltage changes and used OEM chargers it wasn't dangerous. Then I started paying attention online to how many people will plug their phone up to any charger they find buried in the back of their family's chicken coup dumping grounds.
Lipo batteries are MORE dangerous and susceptible to overcharging than Li-Ion. Lipo batteries expand when at a high state of charge, and overcharging causes rapid degradation of the cell, to the point where it short circuits itself and explodes in flames. That's why those of us in the RC community use fire socks to contain charging Li-Pos...

My old droid X came with a LiPo batterry...after just 4 months of use it started to expand and get very hot...luckily i heard about this issue and bought a li-ion and the phone still works the last i knew...i gave it to a buddy like a month or two ago.
i think Rezound take more power then its tell in idle mode
for example if the phone idle for 10 hours and u got 50% left its will drain faster
then using it for 1 hour and then get 50%
also using the phone while recharging make the battery percent not correct
slow recharging can help battery recharge more energy

MPJ 6000mah extended battery

Here's a quick over view of my experience with this battery. So far I've been very impressed getting over 10 hours in SOT. It makes the phone about twice as thick at the bottom 2/3 but is actually quite nice to hold still and not too heavy. The actual capacity is massive I'm sure its the 6000mah they claim which is surprising considering how cheap it is relative to the other brands.
The back cover that comes with it does feel cheap and flimsy but I purchased the honeycomb case with the battery so that is not a big issue for me. My major concern with this battery is its voltage. On the battery it is printed that the Max charge voltage for the battery is 4.2V (the standard lithium ion Max voltage) but the lg g3 takes its battery up to 4.35 volts (due to modern phones using a slightly different li on chemistry). Constantly taking the battery to 4.35 volts when it is only designed for 4.2volts will significantly shorten its cycle life. For this reason I'm using an app called Battery charge limit to only charge my phone to 92% which is equivalent to around 4.2 volts.
Overall highly recommend it and the honeycomb case if you want to give your lg g3 a new lease on life and massive battery life without breaking the bank. Time will tell how long it'll hold up. Saw reviews saying after 6 months the battery swells up but hopefully by limiting how full it charged to that can be prevented.

Don't all g3 models use same battery? I have the d855 and it works fine. You lose NFC and wireless charging but I didn't use em anyway.
As long as your battery is BL-53YH it fits fine
Ah yes. That one I got aswell.
Not only acts as awesome battery, but comes with a SUPER COMFY case (feels icky going back to the usual case, this is way more handfriendly)
It should work for D855 too;
I bought one from aliexpress which was stating 7500 mah but the SOT is still the same with original battery. I tried some apps to estimate the capacity which actually was ~3000 mah.
So I dont want to waste money again. Can you share some screenshots for your SOT? BTW the shape of the battery and back cover is the same as this one
Nah haven't got any screenshots sorry mate, my g3 died of the dreaded screen flickering and fading bug. Trying to sell my extended battery now actually. But anyway I guarantee its an extended battery was getting 6+ hrs sot when I was getting 3 before. You can also look at the Hyperion 6000mah battery pretty sure it's a clone of the mpj or the other way around. You can look for YouTube videos of people using the battery too btw. Cheers.

SAMSUNG: Don't let your phone drop below 50% and don't charge it more than 80-90%

http://techlife.samsung.com/tips-keep-smartphone-charged-1059.html
Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

Wow I did not know any of this. I will be following this thanks for sharing.
how long is the battery lasting if you are only going down to 50 and up to 90?
Gees! Below 50% really. I would tend to agree somewhat. I never let my phone fall below 20% and usually charge until 97% more or less. But 90-50. I don't want to be walking around with a battery back. I need my phone to last all day and 40% of the battery just won't cut it.
Xuck that !! I have a 3000mah battery for a reason if it goes then it goes ill most likely have another phone by then.Not gonna sit here to nickel and dime my usage that's not why I got this phone .
GM makes the Li batteries last in the volt and bolt 10 years by not letting the car drain the batteries more than 2/3rds down, leaving the batteries at 1/3rd charge. Tesla does it too.

Nah, I don't own my phones for more than a year so this doesn't apply to me. I'd rather keep using it from 100-1 just like I've been doing for years. I wouldn't be able to stand only getting an hour of use and charging it 3 times a day.
This battery information applies to all devices that use this type of battery be they Samsung or other brands. Its not just the Note 8. It applies equally to your Oral-B tooth brush! :laugh:
Ryland
this is a good habit to charge often at 50%. i usually let the battery run down to like 20% or less then charge. then when i have to go somewhere and i cant play with my phone anymore cus i worry i going to run down the battery.
Question are the "300-2500" charge cycles just as it says? I mean if I put it on the charger in the car for a 10 minute drive is that a cycle along with an overnight charge? If it is we should really only be putting it on the charger from the 50-90% with a guaranteed fast charge time of at least 30+mins to get the maximum charge cycles for the lifespan?

This was a really well written down to earth article about battery care. Thank you. I still have friends, family, and coworkers that insist on running their batteries to 0%. I can't convince them otherwise. Although my batteries degrade, it's never been anything easy shattering. Just notice an hour or two shaved of over a couple years life. As the article states, there is no way around this and I won't be a slave to my battery. In that note, I top off when I can.
My battery on my old phone tended to get to around the 40% at the end fo the work day, then I'd plug it in usually around the 20-30% and it still lasted 2+ years 'til I got a new battery. Now it's about 50% at the end of the day. But with Fast Charge, what do they expect people to do, plug it in for an hour, then unplug it, then go to sleep, wake up with 60% battery, go to work and then charge it for an hour when you get there?

Too black and white.
It is possible to offer some water resistance to a mobile that has a removable battery, S5 for eg.
In general such water resistance is small and is often abused by the owner causing problems. Hardly any owner reads the instruction manual that outlines what ones device can and cannot do, what the IP rating means in REAL terms etc
"Forced obsolescence" mmmmm, a battery can be changed in the Note 8. I understand your point though.
Ryland
this has been around for years. Doesn't make it very convenient to use nothing below 50%! I'd need at least an 8000 mh battery!! Therefore Samsung IS using too small a batteries in its top of the range device!

Totaly agree......
We then have to ask 'ourselves' WHY! Who forced Mobile brands to make anorexic devices? WE DID. We wanted thin small large wide slim ...........we got it and now pay the price.
I personally don't care if the device is thicker with a larger battery, for me its not a problem. For so many size was a major issue so the manufacture's listened and came up with these ultra thin mobiles that are vulnerable to dropping and breaking etc. off topic.
I find it totally bizarre that we spend mega bucks on such devices only to find we are educated to use them on software that reduces said mobile to the performance of a phone costing 100€! I may add many posters where disappointed when the Note 8 didn't have a 4k screen! Can you imagine the battery issues then?
Now we read this Samsung article and find we would need to charge our mobile several times a day as well as run it on a vastly reduced software programme. In reality that article is saying the battery is only operating efficiently at 40% of its total capacity before we start to degrade its life! Its all so absurd. What are we doing here folks?
Only one answer to this, either drop the performance OR vastly improve battery technology and fast.
Ryland
I'm not sure how usefull this is for the new samsung phones though, as the release of the S8 Samsung improved the battery.
Samsung Mobile R&D VP Bookeun Oh told me, "I focused on maintaining the durability of the battery over the long term, over hundreds of charging cycles. For example, after approximately six months of normal usage, the battery in the S8 will outperform previous batteries. While most batteries hold about 80 percent of their charge after two years in usual cases, this battery should be capable of 95 percent of its original capacity."

PC mag S8 review
I am sorry but i will use my phone all day and charge overnight. If you can't use past 50% what is the point???? My pixel xl i have had since day 1 and use all day everyday and charge overnight and noticed no real decrease in battery life except a little change with oreo!
Outdated info and not necessary.
0% on your device is still considerably above what is considered the bottom line cell voltage before excessive discharge detrimental affects capacity.
A lot of engineering has gone into these devices to squeeze every possible mAh out of the packs, have a decent life expectancy AND operate safely. There is no need to strive for certain numbers and forcibly change your usage habits. There may or may not be a demonstrably better result long term but honestly is it worth worrying about?
And for removable packs...
Forget it. That's a thing of the past.
If devices had battery life like the Skyrocket, sure I see the NEED for a swappable pack.
But not now.
Having a sealed device makes it feel solid and keeps intrusion protection intact.
Holding an older device in hand, it seems almost laughable today. It creaks and groans and feels super cheap in comparison like some dollar store toy!

40w Charger, Safe to use often?

Hi,
I love the speed this charges … up 12% in the time it took me to make a coffee but that got me thinking...
Is it safe for the longevity of the battery to use whenever its time to charge or your phone or should you really only be using it in them times you really need a fast charge and keep a puny 2a 5/9v for them longer periods, such as overnight
EDIT: and now that's about 40% and the charger is pretty toasty, battery warm to touch also
Let be any Lithium batteries, slow is generally safe and will guarantee longevity of battery. 40W is a Huawei's throw in the face answer to OnePlus, that's it. So I would suggest 5V-2A to be good. 500mA laptop output is safest in my opinion, slow yet tension free.

No, of course it's not safe to use it often. I'd limit it to once a year, personally.

If it was risky, Huawei wouldn't offer it, particularly after the Note 8 disaster.

Well Dave, I said for its longevity... not is is at risk of catching fire like the Note 7.... and that was do to with their faulty batteries and not their chargers
yeah it would degrade the battery faster than a slow charger if you use it daily and keep the phone for 2 years you might notice it. I'd suggest a slow wireless charger for overnight charging (it also causes more heat that plugging it to a cable doing 5V and 0.5-1A but it is pretty convenient to just put it in the pad right before going to sleep and in the morning just pick it up with one hand) and 40W for fast boost when you need them
I think they've done their homeworks and it's safe to use for longevity. Looking at numbers in AccuBattrry, it charges as fast as 7000mah at first but once it gets around 90%, it slows down to like 500-1000mah (note I didn't check this over and over thoughrouly) to help battery longetivity.
That said, I don't think anybody here can often anything more than a personal opinion. Unless we can find a technical document from Huawei regarding this, I'd say nobody knows and we'll see in a year or two...
That said, the phone battery is supposed to be 4200mah but so far AccuBattery always reports 4000mah after each charge (it used to be accurate on my old s8).
Wonder if I'm the only one? Or is Huawei 100% charge actually stopping at 4000mah and saving the last 200mah for better longevity so it takes more months or years before it feels like the battery lasts less time?
I'm sure they know what they are doing. If you look into how batteries work (any batteries, the same rules apply to your car battery) they can be fast charged without harming them up to a certain percentage. After that, trying to cram the juice in reduces longevity. This is all well understood at this point, and they wouldn't ship the phones with the 40W charger if it meant a chance of evidence coming out that this harmed the capacity or longevity (number of charge cycles) anytime soon. At max charging speed the phone barely gets warm, which was always a tell-tale sign of overcharging.
On a side note, the 2013 Nexus 7 (which had a terribly underpowered SOC/battery for the screen) was so terrible at drinking the battery that custom firmwares gave you the option to only charge the battery to 95%. Note that this has nothing to do with charging rate, or any of that - simply a cap on that last 5%. The result of this was an estimated SEVEN TIMES bigger amount of charge cycles for the battery. In other words, even when you trickle charge a battery for that last few precious percent, you are doing damage - that is inherent in the design of all batteries.
The efficiency of this Kirin 980 is *ridiculous*. They said that the battery would last 2 full days. They didn't mean it *could* last 2 full days, they meant it *will* last 2 full days - even under fairly heavy usage. It is almost impossible to believe how advanced power consumption efficiency has become, especially given that this is an 8 core (on the main 'CPU') fab capable of performing 5 TRILLION floating point operations per second. I don't think people realize the scope of that number - it makes an S9 looks like an 8 bit Nintendo by comparison. Like the A12 Bionic, it is nearly 10 times the raw processing power of the iPhone X, which was already handily kicking in the ribs of any other phone by orders of magnitude.
