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.

But 500mAh from laptop is not stable and clean enough. It should be high quality charger
No, of course it's not safe to use it often. I'd limit it to once a year, personally.
[/sarcasm]
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.

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 ?

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

Those are wakelock issues that are easily fixable...have you looked into this and disabled them....alot of people have had alot less battery drain after doing so...i suggest viewing whats juicing down your phone to ensure that is what it is...a few of the 4.3 threads have explained the issue....LiPo batteries i hate to say it are made cheap and you get what you pay for...i'm speaking from pure experience
Hi fellow l9'ers
I purchased an OEM battery to have as a spare battery since I'm usually out of battery when I most need it but forget to bring it or charge it. After having so-so experiences with aftermarket extended batteries on other phones I decided that if I wanted good results on the cheap I need to make it myself. Still testing it out but initial impressions are good.
BTW.. yes it looks horrendous and I do know that it could blow up, ruin my phone, cause cancer and start WW3.... but thanks for your concern.

9/4/13 Update.... after using it on a daily basis and swiping back and forth between the oem battery and my jerry-rigged battery I can say its definitely working. The performance has gotten constant and I did a battery drain comparison between the 2 using the app called FAST DISCHARGE. All option selected and cpu set to full load with temp set to unlimited. I did remove two of the jumpers and only left positive and negative connected.
OEM BATTERY........... 2hr 5min 13 sec
JERRY-RIGGED BATT..........3hr 35min 21sec
I suspect that it doesn't last double since both circuits are being powered when charged...... the first battery to be fully charged send a signal to the charger to shut off hence the lack of full power.
Over all for $10 bucks I'm not complaining.
How does the battery stay in place? double side tape?
Also, what is the battery life on this uhmmmm... phone?
How is it?
I am very interested in trying this if your results are good...How has your battery life been affected? Has it doubled? Do you use a case that works with the new "power bulge"?
I did that to my old i897 captivate. you only need the positive and negative connected. you're connecting the two circuit boards together which may cause problems. i would remove that one. Unless you can find a battery charger that supplies more amperage you most likely will never get that battery fully charged no matter what the android meter says.
Ok, after a few days of heavy usage I have come across sporadic performance results. In a few occasions it would out last the original battery under the same usage and other times it would perform as a stock battery. I plan on purchasing an external charger since I suspect that both batteries are not fully being charged as the previous post mentions. I will also disassemble the second battery and take the circuit out of the equation. So far I am pleased with it's performance even though it's not consistent.

Cool. i work in batteries so i didnt check out dudes guide other than his soldering was good lol. essentially all you're doing is connecting the batteries in parallel. since both batteries have a circuit board that controls low voltage and temperature safety, you only need to use one as the battery will still be a 3.6v cell just double the capacity. stock LG charger shipped w/ L9 outputs .85 amps so if you could find one that did 1.5amps or 1500mah you'd be in good shape.
Like @Meda808 said,you only need to connect two pins... + and -.You will also need stronger charger but... There is a circuit in a phone which controls power to battery(I think that that's why is one of the two middle contacts on battery) so... Maybe with external charger?

Small update......
So far so good, no major issues. I purchased the anker standalone charger and it charges the battery but it takes way to long(10-15hrs) So I just charge it in the phone now. The battery lasts me a full day under heavy heavy usage. Prior to this by 2-3pm it was out of juice.
I have noticed that it has become less sporadic the more I use it.
Iheartradio 4-6hrs a day, dish anywhere 2-3hrs a day, calls:30-1hr. This is with WiF(thanks Home Depot), data and Bluetooth(LG Tone)on for most of the day.../.. I'm happy I did it.
I unplug at 4:45am and plug it in by 8-9pm with about 20-30% left.
I have not modified the connection yet so I suspect that it still might not be fully charged even with the aftermarket charger.
About the hump..... I got use to it quiker than I thought.
hahaha ill give ya props for ingenuity

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:

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!
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.
Hi it's been a while since I have been on here. I just wanted to say that googles decision to aggressively cut back the charging as the battery fills is one of the best things they have done in a long time. I personally have used a chargie on all my phones since the pixel 2xl. For those of you who don't know what chargie is it's a device that goes between the brick and the phone and is controlled by an app using BLE and you can set the parameters however you like. I had the phone charge to 80 then it cut power and dropped 3 percent to give the battery chemistry time to settle down then it would.lick back on and charge back to 80 and repeat until I unplugged it. It also has a top off feature that you can set so you can have your phone at 100 before you go if you have a nice set routine which I do not. It also cut the wattage down to like 7 what's or something so there was no fast.chsrgine there. If I did need to fast charge I would use the 30w charger I have. Anyway chargie did not work with the pixel stand so I paied for the pixel stand and pretty much never used it. Then I saw an article about Googles new charging policy.. I gotta say I am so happy now I can use my pixel stand and my phone pretty much never charges past 79 which is fine for me. And if I need it to charge to 100 I just reset it and turn off adaptive charging. But it's very rare 5hst I need to do that. It was a smart move on googles part because there is going to be people who keep this pixel 6 for the full 5 years and if the battery doesn't last they are going to be replacing batteries constantly.
For anyone who has any doughts about this charging method and how effective not is let me just say that I have a pixel 3a xl that we got as soon as it was launched it was my wife's phone for 2 years it is now being used as a security camera. It has always had a chargie since the day I got it. And now it sits on plugged in 24/7 but I still use a chargie. Let me just tell you according to accubattery the health of that battery is still at 99% capacity. And it has been sitting on a charger for almost a year straight. That means almost no degradation to the battery. I don't.know about any of you but I find that pretty amazing.
I hope.that other phone manufacturers follow suit and build.these protections into our devices. It is good to have the capability to charge up fast in a pinch but that should be the only time it is used in a pinch. The rest of the time slow and steady wins the race. I think everyone should look into chargie it works for anything with a battery not just phones the newer ones can set a pre determined limit and not even need the app. And I in no way shape or form work for chargie I just really believe in their product.
I totally agree with you on this. until we are able to obtain the new battery tech that are currently in R&D, we have to protect the current gen and make our device last as long as possible.
I just got my new pixel 6 yesterday and for the first week I'll be charging it to 100% back down to about 20% to check it's capacity and to get an estimate how long it could last me with my usage if I ever need to be away from the brick for some time. Accubattery is also running to put it all in numbers for me.
Once this is done, I'll set adaptive charging and let it charge to 80%, then unplug. I don't have the habit of charging while sleeping so I'll use 80% as my max normal ceiling. usually adaptive charging will slowly top it off to 100% just before your alarm goes off in the morning but i prefer leaving noting plugged while asleep...can never guess when those things might explode/cause fire.
Fun fact: samsung also has this thing in their settings now. they let you enable 85% charge. once enabled the phone restarts and still shows 0-100% but in reality charges the battery only until 85%.
Referring to stuff made out of graphene?
I'd love to see graphene supercapacitors for powering phones. While they have somewhat lower energy densities (1/2 or 1/3 capacity vs lithium), they're light and would last virtually forever. I'd happily double the thickness to get this.
However, the industry is probably going to lean towards graphene batteries. Substantially HIGHER energy density than lithium, and generally performs better in almost all areas, but its still a chemical battery.
So last a few weeks on a charge? Or charge instantly whenever you want? Either would be a lot better.
Battery tech has a long way to go IMO.
I mean we are making power with rocks. Kinda says it all.
I practice these same things to extend the life of my rocks
