[Samsung Galaxy Note 10+ Questions & Answers] Collin80:
As everyone (basically) has said, it is likely that thermal management will come into play here. Lithium batteries can be terribly sensitive to temperature. At the upper limits they quickly run away and nobody wants a bomb in their pocket. But, also, batteries work best at a slightly elevated temperature. Everyone who has ever driven an electric car in the dead of winter can attest to the sort of range and power lose you can be prone to. As such, I'd actually suspect that getting the phone too cold would also limit charge power. The ideal temperature of the battery is probably around body temperature which is perfect for something you carry around.

It is likely that the phone will not charge at 45w except in laboratory conditions. If you have a temperature controlled plate to put it on and you can tightly control the temperature of the phone and use the exact right charger with a perfect cord stretched out perfectly with no loops and the phase of the moon is right and the planets are aligned you probably can get 45w for a few seconds before the perfection fails and it go back down to the high 30s again. Note that this is all that is required for someone to claim it is possible. It only need be possible in the most perfect conditions. But, being able to get 35-38W charging sounds pretty good to me. That's close to the theoretical maximum. Nothing can push the maximums forever. Back to electric cars, you can't drive a Tesla pedal to the metal for long. It overheats. You can't drive it, super charge it, drive it hard, super charge it. It overheats. Sure, something like a Tesla *CAN* do 150KW/hr charging but not for an hour. It gets hot. Likewise, phone batteries get hot, the cord gets hot, the charger itself gets hot, parameters change, you can't expect perfection. The rated specs are the absolute maximum not something you should plan your life around.

Hi,

I just checked the links posted by the op and can surely verify that Samsung certainly made that claim and it was claimed to be one of the main features exclusive to the note 10+. They have stated that with this super fast 45 w charging capability the phone could be fully charged in 30 minutes.

If that can be done I won’t mind shelling out an extra grand on the 45 w charger as it means cutting down charging time by 50%. I have to say though when I initially got the note 10+ and saw it get to 8% late evening I set it to charge while still doing part of getting it to be my phone with my preferred apps etc.

I was very surprised to see it get to 100% as fast as it did and that brought a smile to my face every time because we all know bigger batteries mean longer screen and standby times but it also means much longer charging times but this one was a pleasant surprise but 30 minutes is way cooler.

Many friends, and seniors here must be aware of the Graphene battery which they got a patent on that goes from 0-100% in 12 minutes! They also said abs many other experts working on graphene tech have validated the fact that a graphene battery offers 4-5 times the ampere hours if made to the same size as a lithium ion in use because of the higher energy density it offers.

They have also adopted the Intel and other hardware makers’ strategy to release improvements slowly over a longer period instead of letting us use and benefit from the huge leaps that advanced and alternate technology allows devices to progress and transform.

A false claim is certainly an actionable claim for customers.. we should’v be thinking on the lines of “we can’t do anything about it”. We pay the prices they set which are surely unreasonable but we do that to get the latest and greatest in ideal circumstances we should be getting more than we paid for even if it is marginally more but not getting something that was one of the main features advertised is definitely not right. That’s my opinion and I appreciate the fact that not everyone may agree or disagree with me completely and am fine with that.

I’m always open to learn from the many good people on Xda who work so hard and give us these fabulous Ron’s and tools and methods to modify and even repair software bugs and glitches on our phones for free. Thanks for everything you all do. I have a question for all the people here but it is not with regard to this thread so I’ll post it in q&a. It is about Samsung and how they are playing us for fools in the smartphone market for one. Feedback and corrections are welcome. Edit: This is the q&a section, I meant to say a new topic. Lol.

[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
Don't expect that much more from the 45 watt brick from all I've read.

For the 25 watt brick 2% @ minute is nominal till about the 90% mark. This is fairly fast charging.

Use a damp rag if the ambient air temp is above 95 F; charge rate will slow or even stop if the battery temp gets too warm.

Charges above 82% and especially >90% are undesirable as they greatly decrease battery lifespan.

I shoot for a 62-72% partial charge when it has discharged to 30-50%.

High temperatures plus a full charge degrades LI batteries the fastest and can cost you many hundreds of lost full charge cycles.
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
I found this forum post when I discovered the same problem. The maximum charge I've been able to reach is [9.62V⎓3.78A] = 36.36W using a J5Create JUP44100. I have the 45W Samsung charger on order and will report back, but it sounds like this is a Samsung induced limitation. Very disappointing we're not getting what we paid for.

I also found the charge rate plummets when the screen is on at certain charge levels. I need to investigate further but if anyone knows the specific behavior that would be helpful.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
36 watts is a lot for a Li cell this small. The idea is to control the cell charging temp to minimize degradation and prevent a runaway thermal reaction. Somewhere above 80-90% charge rate is decreased to protect the battery.

Somewhere below 60F or so fast charging is disabled to try to prevent Li plating.

For best life and fastest charging do this:

Limit most discharges to 40%

Don't go below 20% or above 90% as this stresses the cell needlessly.

High temp and cell voltage degrades the cell much faster than lower values.

Never attempt to charge if cell is close to 32F or below.

Avoid charging if cell temp is below 70F.

Stop charging if temp reaches 100F; in another few degrees it will auto shutdown anyway.

Ideal charge start temp is probably in the 75-85 F range.

Li's love frequent, small midrange charge cycles which can increase it's life by hundreds even thousands of full charge cycles.

From 40-65% is perfect. Over 2 hours of SOT and only 12 or so minutes to fast charge it back up.

Find and correct battery hogs; they needlessly waste power and battery life.
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
I know how batteries work...

If they sold us a 35W charging phone there wouldn't be a problem. They specifically said 45W and sold a 45W charger to accomplish it, yet only achieved 36W.

36W is impressive, but it's significantly less than promised.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
The 45 w brick is slightly faster than 25 w; I think it's about 10 minutes faster for a full charge cycle.

The biggest difference is in the 6-30% range but the difference narrows as the charge level climbs.

The overall difference isn't that great but the 45 w brick is faster.

It's not the brick wattage the limits the 45 w brick but 10's onboard controller; it maintains safe charging parameters throughout the charge cycle.

The top speed of the 25 w brick is 1% every 30 seconds, like clockwork when in its fast charge mode.

If it defaults to slow charge it's 1%@minute.
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
It doesn't appear that you are reading my posts. I know how they work, I know you're not going to get more than 25W for most of the charge, and I know that the maximum charge occurs at the lower end of battery SOC. I also know that it's not the charger's "fault". It's Samsung's fault because they advertised 45W charging and only delivered 36W.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
I wouldn't get too worked up over it. At some point in the charge curve under ideal circumstances it may use nearly 45 watts.

That's the problem with the need for speed; cars, bikes, women... the return curve starts rounding off at the top.

You get less bang for the buck at the high end.

Consider it future proofing for the next phone.
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
No, it never comes close to 45W in a 15C room.

If the Note 10+ charged at it's advertised rate, the 45W charger would be significantly faster then the 25W charger is shipped with.

You hopefully said it in jest, but considering Samsung's latest phones only support 25W, I'm not so sure about your "future proofing" quip either.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
15°C is 59° F

At that temp fast charging may not even engage if so it will default to slow charging.

Try starting with a minimum battery temp of 80°F* The 80-95°F range seems to work best for this phone when fast charging.

*The centigrade scale's resolution sucks compared to farenheit scale for real life temp indexing.

Yeah, I know bad science... until you witness how much easier it is to use whole numbers in real life.
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
You're obviously a robot sent from Samsung to distract this thread. Fast charging is designed to work at room temperature.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
Room temp is 72°F for most people.

Obviously the centigrade system has you all shook out... try using 26.6667°C 🤣
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
We keep our rooms colder than most but it's definitely in the range devices are designed to work. I've just tested this again at 20°C and had the exact same result. If the only way to get these to 45W is to do it in a room that's 26°C, then it's a defective product.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
Below 72 F (some say 80 F) Li plating can occur.

The colder it is, the more likely it will occur.

When the room's cool I make sure the phone isn't before starting a charge. At the least I wrap it in a microfiber cloth to help bring its temp up.

If it's charging at 2% a minute be happy... anything above that is icing on the cake for this generation of phone
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
2%/min is your standard for happiness. How long does it need to hold that for you to be happy? 1 minute? 10 minutes? Is it worth the extra $50 on top of the $1100 spent on this premium device "capable" of 45W charging?

The phone doesn't come close to 45W at any point in the charge cycle. It would be faster if it did, which would make the investment and the size of the brick make sense to me.

A 3 second 0-60 car is fast, but if they advertised 2 seconds, it's a failure.

The 45W promise for the Note 10+ is a failure.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
You're crying over spilled milk*. It's not chump change but thankfully less than a Franklin.

With Samsung you really need scrutinize their products, specs and user reviews before you buy.

Snap buying new Samsung rolls outs isn't a good plan... so I've learned.

I got lucky with the 10+ as Samsung's been back sliding since.

So for you there's that; be glad you have a 10+ and don't "upgrade" to Q if you haven't already!!!

* I would encourage you to demand a refund if you believe it this much. It be hard as hell but getting it be a feather in your cap.

Lol, I have a $350 refund check from Sony; that's like getting blood from a stone.

Assertiveness, you can never have too much. Think of getting the refund as free lessons in assertiveness🤣🤣🤣
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
I bought the 10+ for a lot of reasons. It was an extra $150 over the 10, and one of the selling features of that extra $150 was the 45W charging (plus $50 for the charger).

I'm happy with the 10+ overall, but the 45W claim was a lie. The charger is going back with full refund.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
The 10+ is probably the best overall Note ever released... maybe the last if Samsung doesn't get their clown act together.

I hope you get the refund... do what it takes.

I don't believe in rewarding bad behavior or misleading specs.

Please keep us updated on your progress👍
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
If the 10+ had a flat screen I'd say it's the best they've built, but honestly it's been downhill ever since the Note 2. The 10+ will be my last Samsung phone for a while unless the 2021 Note is a showstopper with a macro camera and flat screen.

The charger is still in the return window so no worries there.
[Samsung Galaxy Note 10+ Questions & Answers] blackhawk:
It took some getting use to and finding a good screen protector was a chore.

I use the curve to house One Hand Operation + so it's not wasted space for me.

This is a great and versatile app, much better than the native Edge. Uses almost no battery, no internet connection. Rock solid stable.

Occasionally when cut/pasting the curve gets in the way but normally not.
[Samsung Galaxy Note 10+ Questions & Answers] Hung Start:
That looks like an interesting app! It appears to work just as well on flat panels though.

The glare on the curve is probably the most irritating drawback. It basically eliminates the far left and right 5% of the screen from view.

That's what it looks like, but I get 5g sometimes with AT&T. Some of their mid and low bands are compatible. I think more bands are opening up in the US so who knows what eventually will happen. I don't believe Huawei has launched the European version yet. They were waiting to see if the ban would be lifted so they could launch with Google play. Check the bands on gsmarena they have both models listed and the bands for each.

If you're referring to the 5G radio aspect and compatibility then according to gsm arena they all have the same frequencies.
