Looking for usb charger with auto turn off with 2 AMPs! - Galaxy Note II Accessories

Hi! I'm looking for a charger with auto turn off with 2 AMPs. I'm in USA so links to local shops or smth like amazon are welcome
Similar to this one, but 2 AMPs NOT 1: http://www.cooperindustries.com/content/public/en/bussmann/consumer/products/chargesmart.html
I want to use it with my battery charger: http://www.samsung.com/us/mobile/cell-phones-accessories/EB-H1J9VMAGSTA
Because with that thing you can leave your battery to charge for the whole night & not worry that you miss the moment when you should unplug it. It charges exactly as much as needed & doesn't damage your battery!
I wonder why all vendors don't make charges like this one. Maybe to sell more batteries?

Just an FYI but all phones stop charging when the battery gets full.
Also it only costs about $1 per year in electricity to keep charging your phone.

Just use the original charger for the Note2.
At least the european version of the charger delivers 2amps and
when the Phone is full or nothing is connected to it the consumption is so deep that i couldnt measure it.

why not you using your note 2 original charger & cable ?
it sure deliver full 2 Amp and able to cut off power when battery is full

I'm pretty sure what the OP meant is they want an auto-off charger to be used with the battery dock charger. Sure, the phone has an internal controller that stops charging when the battery is full, but I think the OP wants the auto-off feature with charging the battery as well. I'm not completely sure, but I believe there should be a charge controller inside that Samsung dock. If you're up to the challenge, you can take apart your battery charger and see for yourself. Any kind of circuit between the charger and the battery should be the voltage/current regulator, and quite possibly the charge controller.

1) The phone looses 2-3% overnight. So when it charged to 100% & then looses 1% it starts to charge again. I think it's called "trickle charges" & I was worried if it could reduce the battery's ability to charge to true 100% in the long term.
But I read several articles about it & looks like with today's batteries this is almost not a problem & you can leave your phone to charge overnight.
2) I know that exposure to heat is the worst thing fir litium batteries, but several articles confirmed that there's no such a problem with today's phones & batteries.
& it was not about electricity bill anyway )
& yes I do use both original Samsung charger (travel one with 2 amps) & Samsung docking station to which I posted the link in my first post.
Thank you guys!
Here're the prooflinks to some of the articles I've read about overnight charging, maybe someone wants to read them too:

The problem with lithium ion batteries in our phones is that it has a shelf life rated at 2 years. By the time you were able to wear your battery down through it's rated cycles, it would be time to get a new one anyways. I would suggest to buy a new battery in a year or so which should last the life of your phone if you don't sell it or upgrade.
If you find what you want, awesome. I see it as unneeded waste to buy something like that if integrity of the battery is an issue. Each battery has an IC chip that controls everything needed to operate at its' maximum. Any gains in battery life would be negligible due to its' shelf life. Sorry :/

Battery to 100% - Required Parts

First post here, be easy on me. I love this Nexus S, my first android phone, but man this battery issue has really bothered me. I would wake up in the morning, take my phone off the charger and immediately be at 96%. After 15 minutes of checking emails and surfing, I would be below 90% by the time I got to work an hour later. I was spending half the day charging my battery, so I decided to order 2 OEM batteries and a wall charger off Ebay.
Well little I did I know that this would solve two problems. First, the wall charger charges the batteries to 100% and provides significantly more life. For some reason the phone does not let the battery truly get to 100%. Second, when I get home from work or wherever, I can just pop in another battery and be fully charged again. Now I don't have to sit and worry about charging my battery all the dang time, and my batteries are lasting much longer to boot using the wall charger. I am not sure I can post links yet, so what I ordered was an M9P wall charger for like $10 and a couple extra OEM batteries for $10/per on Ebay. I ordered from US sellers so I didnt have to wait weeks also. You might be able to find cheaper if you order from a hong kong seller. Anyway, I hope this helps someone as frustrated as me.

No trickle charge is applied because lithium-ion is unable to absorb overcharge. A continuous trickle charge above 4.05V/cell would causes plating of metallic lithium that could lead to instabilities and compromise safety. Instead, a brief topping charge is provided to compensate for the small self-discharge the battery and its protective circuit consume. … Typically, the charge kicks in when the open terminal voltage drops to 4.05V/cell and turns off at a high 4.20V/cell.
There is a whole lot more info on that site, but I’ll sum up the excerpt, if you continually charge a Lithium Ion battery, it will degrade, and worst case explode, but hey, at least it looks cool when it does.
Just don’t end up like others have, for example, a Chinese man who took his phone off the charger, put it in his pocket, and then it exploded. To read a little more about that, check out EnGadget, if you want to see the phone, Tech-Ex. Here’s another one, no one was killed, but it burst into flames, over on PCWorld.

IMO. I rather have it sit at 95% than to have my phone catch on fire. Better safe than sorry.
I've been charging my mobile devices to 100% for years with no issues. I'm not too worried about it since I don't mod my phone. All I wanted to do was have a battery that lasts and I now have that. Thank you.

From what I am seeing and how much longer my battery is lasting, I am getting a fuller charge and WAY longer battery life charging batteries in the wall charger. I had the same issue as many others with this phone. The battery wouldn't charge to 100% and general battery life is pretty poor. I thought my phone was bad so I exchanged it and the battery life was identical.
I recommend everyone who questions my results, if you have a spare $20 and are sick of the poor battery performance of this phone to get a wall charger and spare OEM battery off Ebay or wherever. Theories are nice and everyone has one but I'll take real world results over theories any day.

"WAY longer battery life"? Really really? I'm having some trouble believing this. The standard battery is 1500mAh. Are the extra batteries the same capacity? Because we are talking about something around 4-6% more power here.
This is either confirmation bias or blatant advertising.
Edit:
Fun fact: These two listings are from different sellers, but both write "Samusng" instead of "Samsung".

Obviously i'm not advertising, I am just posting my observations. My battery is lasting several hours longer than it did before under similar use. Right now I'm going on 6.5hrs of light use and I'm still at 81%. The OEM batteries I bought show the exact same part # as the one that came in the phone, but say 1440mah instead of 1500. I'm not observing any difference in how long they last compared to the original battery as today I am on the 1440 one.
I've been in the IT field for 18+ years. I know the difference between real results and 'confirmation bias'. These are real results I have experienced. You are more than welcome to share yours if you choose to spend $20 and duplicate what I did.

I don't believe that unless your wonder-charger is literally cooking the batteries to death by some serious over-charging.

So, the original battery to 1500mAh, charged to 96% in the phone would give ... 1440mAh. And range anxiety.
But the extra batteries, charged to 100% in the wonder-charger would give ... 1440mAh. And a peaceful feeling.
Yeah, I don't really see the "WAY longer battery life" here. If those 4-6% extra charge gives "several hours longer" then a full charge would be good for a couple of days of use anyway. And yet you were "spending half the day charging your battery". There's something odd about your story. The numbers don't really add up.

No thanks. I have that exact same charger, and an extra original battery. If that charger actually makes that much of a difference, I don't want to cook my spare battery to death with it.
But feel free to back your claims by some real numbers taken from, you know, objective tests. One battery charged in the phone, the other in the wonder-charger. Then do the exact same thing (play music or whatever) until the batteries hit 15% remaining. Then post the elapsed times here.
Your condescending tone isn't worth my breath. My results are my results and I wished to share them with other people having battery issues and what I did to resolve them. I will continue 'cooking' my $10 batteries to a full charge and having a phone last several hours longer than it did before I started 'cooking'. You can do whatever with yours. Good luck to ya buddy.

You know this isn't your blog or twitter feed to promote what you're doing.
Just like what you said, you're new to XDA so I wouldn't be too fond on trusting you either because you haven't been around too long.
I'll continue to stick to my battery. Grats on your long battery.
I go a full day with heavy use on my stock battery. Not sure what your problem is. Unless you can put up some real numbers though, this thread is not worth anyone's time.
After ordering both an OEM battery and the M9P charger I can confirm this.
I don't have screenshots yet, but The stock battery and the replacement OEM batteries I ordered. Function at around 4-6 hours more on the wall charger. With the stock charger charging my stock battery, I was seeing around 16-19hours with heavy use(phone and phone+bluetooth/text/web/youtube) with the M9P charger charging the battery, I have seen roughly a 4-6 hour improvement in battery life depending upon the usage change(i.e if i'm playing angry bird or NFS Shift along with other normal stuff)
I am, however, convinced the pulse charging vs. trickle charging done by the stock charger won't shorten the battery life. Plating will be come a real problem later on down the line, but with any smartphone, I don't expect to keep a battery longer than a year with my use before i either replace the phone or the battery.
If you guys want battery history shots, or whatever you might need to to help you get a better picture of what's going on, please let me know. I'd be happy to provide them.

Thanks for confirming my results. I was very displeased with the battery life of this phone, but since I went to the wall charger and just swapping batteries, I am getting a full 24hrs use and still have 10-20% left when I swap before work every morning. All in all a pretty cheap investment for the gains.
I am not seeing any noticeable difference between the 1440mah and 1500mah batteries either.
Just wanted to post my experience about battery life. It lasts almost two days (I switch off my phone for six hours every night). It wouldn't charge more than 95-96% every time. And it took really long time to charge too, with the oem charger. And then I tried my wife's Nokia charger, which is also 5V output but 1200mA instead of 700mA the oem is. And charged it turned on. And there it was! A bit less charging time, and for the first time it said 100% charged. That happened the last 6 charges with the Nokia charger. I hope I am not damaging the battery with what I'm doing. I can't say it lasts more than before. Nothing noticable. But at least it's fully charged and it doesn't take all day to charge.
i get 100% everytime when i unplug it will either drop to 97% or to 96% but will still last a whole day of use. i dont charge my battery unless it turns red with the X or till it shuts itself off.

Buy yourself a cheaper battery: using lower amp batteries with the Nexus S

I have always thought that the amperage of a battery made no difference to the voltage due to the factory adjusting the internal resistance of the battery. Amperage I understood was measured in current, however, which does have an effect on overall voltage.
Recall:
V = I * R
With electronics, it is my understanding that the mAh battery doesn't matter as long as the voltage is the same, although you'd get less longevity out of a 1650 mAh vs a 1440 mAh.
Thus, I believe this battery would work. Thoughts? The part number matches exactly what was in my Nexus S and the batteries look identical. If this is the case, save yourself some money buy not searching Nexus S battery and instead searching ab653850ca in eBay instead of paying $30-$40 for a new/replacement Nexus S battery when they are the same thing.
http://cgi.ebay.com/NEW-OEM-SAMSUNG...Accessories&hash=item3a5dd479e2#ht_1287wt_900
Thoughts? Both are 3.7 volts.
mAh is a unit of electric charge, not current (notice the 'h' making it milli-Ampere-hour). So, yes, a lower mAh battery will definitely work, but it will last less time.
Also (just trying to explain better) a battery is not a "powered resistor", so the relationship between its voltage and its current is not just ohm's law (the one you recall). More specifically, the 3.7 volts is due to the chemical reaction inside the battery and is more or less fixed (although it decreases as the battery discharges). The current flowing is basically a function of the load of the battery, so it changes according to what parts of the phone are working at that moment. The output resistance of the battery is a formal way of describing how close the battery is to an ideal voltage source and is not related to the amount of current it's actually providing.
Sorry if I was not clear enough, it's late here!
Missed the h. Not sure why, I see mA all the time and I just missed the h. Interesting and helpful. Thanks man. Clear to me.
That's strange, if it is the same model (AB653850CA), why is it only 1440mAh? But I'm sure it will work.
All I know is that this Samsung Moment battery I got off of Amazon for $6 is almost as good as my stock battery.
Sent from my Nexus S using XDA Premium App
The 1440mAh batteries work perfect, I have 2 of them. While you are at it, buy a wall charger to charge them in so they will charge to 100%. Having 2 spares means you will always have a FULLY charged battery to pop in and never have to tether the phone to a charger. Plus you get 2 to 4 extra hours of use.
Very informative!

What do you mean by that ? That the 1440 mAh battery only gives you 2-4 hours ? I doubt it lasts so little time. I hope it doesn't.
No he means charging the batteries in an external charger gives them a more complete charge as I find the same thing. I've got 2 genuine batteries and a third on the way and the external charger charges them to 100% whereas the phone only charges them to around 95%. The batteries charged in the external charger last longer than those charged in the phone.
Hard to know when you're legitimately getting a battery with "more capacity" though, so I just assume I'm always buying another stock battery anyways.

Oh, I got it, thanks !
Anyway, for 6$, I think I'm going to buy one, too. Coupled with the 2nd battery dock, it should work flawlessly.
Hey guys,
I went ahead and ordered one of these too. I noticed that the Watts/hour is 5.55 on the Nexus S battery but on the battery I ordered (but have yet to get in) it says 5.3. Is this going to make a difference outside of how long the battery lasts?
If you guys buy one of these 1440s report back with what you've found out.
And if this is a success, then please urge XDA to sticky this thread or put this on the main page. Paying $50 for a second/replacement Nexus S battery is outrageous, and if this saves my fellow XDA members $45, more people should know about this. :]
UPDATE:
Looks like turbodroid already ordered these and said they work great! Thanks guys! Thank me if this was helpful.

[Q] things to be done on battery after getting new htc one

I am new in HTC phones. I will get my htc one after 2 days, i mainly want to know about battery charging cycles. how can we do that to get maximum battery life. what is mean by battery calibration ? is the battery to be calibrated in every weak ? sorry for my bad english
Once at month, you have to discarghe the phone at 0%, put it in charge and switch on it when the led is green.
The battery life, during the day, depens of you and your use of phone
Just use it. Charge it when you need to, charge it when you can, top up charge is fine. Calibration is a myth. You don't need to do anything or not do anything abnormal.
Letting it run out and leaving it empty is a bad idea. Charging it, turning it off, charging it, and whatever other voodoo is recommended is a bad idea.

is their any special charging methods to be done after getting my new One ??
One charge for a day is enough for htc one if you don't play games
If you really want the most optimum battery life out of your phone then don't let it drain below 30% nor let it reach more than 90%. You'll likely get the most charge cycles and prolonged battery life with that. This suggestion sounds sarcastic but this is scientifically factual.

How many HTC one batteries did you test? Using what methodology?
The only scientific fact is that you just made up those numbers, you have no idea what charge and discharge limits have already been placed on the raw cells by the battery circuitry.

I don't use this method.
But my friend have a very good battery life with it.
So, why don't share?
I don't use it because i can't do this, it's simple
HTC One Battery Conditioning

G'day mate. When I had my HTC Desire, there was a process of conditioning that was advisable which pushed my battery life from 3/4 of a day to a full day. Having just received my HTC One last Friday (and what a magnificent phone it is too but that is a story for another day), I can honestly say that no conditioning is required (after-all, it does have a 2300mAH battery). I would suggest that you make sure that the first time you charge the phone, you leave it on charge for a minimum of 8hrs (as recommended by HTC). I left it on charge all day and I believe it does make a difference. As for making it last long, may I suggest you invest in an App called Juice Defender Ultimate (not very expensive but extremely useful) ? I am using this app and I have improved the battery life of my One from a single day to approx. 2.5 days. But I am an average user (emails, some internet, some music and blinkfeed). I don't watch movies on my phone so I am not too sure how that will affect battery life but I believe it will have some effect.
I hope this helps you with the answers you seek.
It's based on scientific facts.
When your battery has high load(Almost fully charged) more ions inside the battery are stored there hence doing alot of chemical changes in the battery. And chemical change is the only reason why our batteries here are losing it's capacity.
And the reason why I set 30% as the minimum is because you don't want your battery to be drained too much as there's likely chances that you'll completely drain it causing it to be broken also.
And why limit the examples on HTC One batteries? Is this a serious question or just a joke? We all know that HTC One was just released months ago and another obvious fact is it has a non removable battery. So obviously the answer would be none.
And about real life proofs about my usage and how it affects battery life do you want me to show you a nokia 3310 model still up and running for almost a 8 years now? Also want me to show you my nokia n900 which is already about 4 years now and still kicking it's battery perfectly up to now? I could have also showed you my n95 up and running till now if only it didn't break it's flex cable.
There's no such thing as integrated ticking time bomb on your battery(like rumors in the 20th century where they say electronic ICs have a hard coded date where they will totally shut off) where it would just instantly die once it reach it's recharge limit. What manufacturer in their right mind would do that? Smartphone business isn't a monopoly and every competitor would want the best of them all on their products. Also if this myth would have been true most people's device wouldn't even last a year due to plugging your phone on a computer would initiate a charge also. So would that mean that if I plug my phone on my PC 5x a day and charge it once a day it would only last roughly 6months? lol!
Also here's a good website that would backup my claim.

Partial and random charge is fine; does not need full charge; lower voltage limit preferred; keep battery cool.

Prevent full cycles, apply some charge after a full discharge to keep the protection circuit alive.

Keep cool, battery lasts longest when operating in mid state-of-charge of 20–80%. Prevent ultra-fast charging and high loads.

How many HTC one batteries did you test? Using what methodology?
The only scientific fact is that you just made up those numbers, you have no idea what charge and discharge limits have already been placed on the raw cells by the battery circuitry.

Did you read those websites? Because their numbers and yours don't agree. So either you made up the numbers or you obtained your scientific facts from elsewhere.
As much as I know....just dont overcharge and frequent charging. Overcharge meaning leaving your phone charged for long hours after it has reached 100%. Frequent charging meaning leaving your home with 100%, reach office at 85% and charge. Going for lunch with 92% and came back with 87% and you charge again. Get the picture? I'm no genius on batteries and dont bother looking up and reading on them. Just based on experience, over many phones. And yes, the first charge is very important.
I thinks the powersave is the best route when not playing any games. If you play games then you can call it quits!

Given that the phone comes with charge in it, how much can you do to affect the first charge?

As much as I know, dont drain the battery too much the first time you take it out the box. All batteries comes with a little charge in it. Had a friend who used to work at a mobile company and I cant remember the term he used to describe that. But the first charge doesnt have to be exactly 8hrs. Phone might be fully charged after 4-6hrs if you hadnt used it much from the box. Just dont unplug it before it reaches 100% on the first charge. Let it get to full and leave it for another 10-15mins and its good to go.

I let a cell phone battery get down to zero once. It never worked again.
I did the same with my house cleaning robot. I had to replace the battery after that.....I'm just saying.

[Q] how much of voltage do you have on full charge?

my battery life is way too short to be true. bearly a day on complete idle, 4 hours with moderate use.
I do drain my battery completely sometimes and quite alot of times even though a usb could be around me most of the time.
I have a phobia of plugging in a charger and pulling it out halfway or after 1% charged, for it might destroy the battery that way.
And yes i googled just before coming here and i realised i did things the other way round. ie i shouldn't be draining completely and i should had plugged that usb when i had the chance even if it meant charging for 1%.
Is there anyway proper way to determine for sure if i had damaged my batttery? My voltage on full charge is 4.333V
Which app did you use to check your voltage so i can check mine and compare?

4.336V here.
It's a two blades sword. If you have more than 4.2V (+/- 0.5V) on 100% that means that you overcharged it. Now it has one positive side and one negative.
Positive one is that you have about 10% more use time, but negative is shortening battery life. Considering price of new battery ( 15$ ) who gives a ****. Reading couple of articles it's best to charge it for 50% whenever you have to (can).
4336 on full charge

Dude even older phones (batteries) have over-charging protection chip.
How can u over charge the battery, I think we spend too much time on this battery problem
For the OP please read this and this you will improve your battery life I GRANTEE YOU!!!
Yes, there is a overcharge protection circuit, but the problem is manufactures manual for battery use thas says that ion-lithium battery souldn't be completely discharged nor fully charged. It is best to charge when it drops down to 15-20% up to 97-99% if you want to prolong battery life.
I think you're missing the point of thread, it is about battery maintenance.
My value was at the exact moment it reached 100%. I will let it "overcharge" and see if it changes.

The 80-40 battery cult crowd.

Was wondering, how your sot and so forth is ?
I get on a good day about 5 hours sot . Would love to hear from those that charge to approx 80% from 40% regularly.
Cheers

Please allow me to comment how mad this is. Whilst I'm sitting at my desk, my phone sits in my wireless charger stand when not in use. My Note 5 still holds a charge fine. My Note 9 will likely perform in a similar way down the road.
Madness....
Best for battery health = keep batt level between 40-80% but for more convenience you could keep it 30-90 . You also free to charge any time within that range

Battery chemistry is certainly madness. Not charging to 100%? That's certainly not madness.
You might not have noticed it but battery degradation is definitely a thing and keeping a battery between 40% and 80% will most certainly lead to less degradation.
A good example of this is Tesla, why, by default do they not charge the batteries to 100%? Battery degradation.

Oh, I'm aware that battery degradation is a thing. Certainly. I'm just not bothered by it to the extent that I'm policing my charging habits in this way. Which to my mind is madness. But that's only my view on it. My older devices still hold plenty of charge for a reasonable amount of time for my personal needs/wants. That's all that matters in the end.
It just seems to me that paying such a dear price for a phone like this shouldn't force me to limit what I can do with it. Again, that's just my view only.

Your older device may hold "plenty" of charge for your personal needs/wants but it would hold more if you'd looked after the battery, it's as simple as that. Some of us choose to look after them, others don't.
Personally I prefer to look after my expensive investments, I don't think that's mad at all.

Looking after investments is not mad at all. Nobody sensible would suggest this. I'm only suggesting that the manner in which you choose to look after your investment seems mad to me. That's it.
I'm honestly surprised I still get use out of some of my older devices. Most users don't tend to keep old phones around too long from what I've witnessed over the years. So the issue of battery degradation is not a big deal for them. Policing my charging habits just seems too much, IMO. Battery tech will continue to evolve and hopefully degradation will continue to improve for us.

You're spot-on,but,you're wasting your time here in this thread,or,any battery life thread in general.
The same peeps could be getting a weeks worth of phone use between charges & still fret over battery health/life.
They're still stuck in 2012 when phones had a 1/4 of the useful battery life that they do now.
This phone does just fine,those w/issues are a small minority & likely do little else than spend every waking moment on their phones.
If there was a wide-spread battery life problem,the likes of BGR & The Verge would be all over it.
Of course,that's not typical use & most "issues" are related to notoriously s****y apps such as FB or,are in a weak signal area.
As for the 80/40 thing,don't you think Samsung has this addressed already w/software?
Of course they do,so,any further fretting over battery health & life,IMHO,is wasted time,there's plenty of other things in life that are more worthy of such attention & concern.

Awesome thread title,LOL. :good: :laugh:

I have monitored the battery on Note8 for a year with AccuBattery. At installation on the first day I had 95% life and after one year i had 95%. It is possible to lose some mAh but not so much. Samsung Mobile CEO says new battery generations lose 5% capacity after two years of use. Not much. After 4 years 10%. Does anyone hold the phone so much that it deserves 40-80% pain? And if you want to keep it for 10 years you can not change a battery under warranty or for a fee? I've loaded my phone daily from 25-100% and no problem.No fast charger.

So it does not deserve any trouble with the new batteries. If you are a power user with games and others and you charge the phone with fast charge twice a day then it can accelerate the damage process. If you are a normal user, you have no problems for a few years.

Since when was a mobile phone an Investment??!
Id be as crazy as some of you folk on here if I cared about caring for a battery. Mines charged overnight. If it needs a boost during the day (so far not required on the note 9)it gets one.
Seriously. Some of you need to chill about battery conditioning.

Well, some would suggest spending upwards of $800-$1000 does qualify as an investment. But maybe I'm wrong.
Lithium based batteries lose capacity in every charging cycle but it's not as bad as some might think.
In 2015, a study by the KIT showed that lithium-ion batteries lose 30% capacity in 1000 to 5000 full cycles (0 to 100%).
The same year, a french consumers association (UFC que choisir) did a similar experience (15 devices with lithium batteries were tested for battery loss in capacity after 300 to 700 cycles of charge from 20% to 100%). The end result was that devices lost up to 14% battery capacity.
The worse battery capacity loss I have seen in an article was from Cadex. 20% loss over 250 full cycles.
So, for people that don't keep their phone more than 2years, there is no reason to be worried by capacity degradation over cycles of charge. (Temperature and voltages seem to be a much bigger problem. For example, I have already seen results as bad as 20% loss after 12 cycles at -20°C).
IMO, this problem is in fact something that is highly important for electric cars.
After a call with Samsung Support they told me to keep the phone over 20% and when it reaches 100% to plug the charger out. No 80% rule...

I have a small desktop fan placed near my main charging spot/dock.
If I happen to charge it up somewhere else,no biggie once in a while.
Regardless,it's a small measure to take that requires no thought/worry.
Old idea for 2009 technology.
Charge when you want.
This wasn't suppose to be a debate about charging habits. But was supposed to be about asking those that use this method a simple question my friends.

I understand your curiosity but if you want to see some differences between people doing 100% DoD and people doing 60% to 80% DoD, you should ask on the forum of an older phone.
Battery capacity loss per cycle (at normal temperatures) is too small to be seen in such a short period of time.
But if you ask buyers of the S8, or even Note 8, for example, you might start to see some differences.
Edit : Assuming that you find people actually doing 100% DoD haha.
