Don't just buy any 45W+ PD charger for your Samsung Galaxy Note10+

25 August 2019
You likely won't be getting the full 45W charging speed and here's why.

GVera, 26 Aug 2019This article explains the issue https://batteryuniversity.... moreI will still buy the 45W to use it outside the house. 2 reviews on Samsung.com say they topped the phone in 30 minutes.

Also another website mentions a Aukey 74w charger that they believe has the same proprietary as the orginal.

    GVera, 26 Aug 2019This article explains the issue https://batteryuniversity.... moreThanks for the article, my question would be: did this info age!? Its true that the batteries concept maybe didnt change but we don't know after 9 years how many of these concepts are still holding.
    After several years of suffering with my batteries (Since my first smart device, HP PDA) I want to see where the problem is.
    My PDA was at fault. Everytime the battery completely depletes the system format.

    But my Notes always suffered from loosing battery fast while non of my colleagues at work has a problem. The question is:
    Is it because I am a rare employee who works across a huge hospital that has issues with WiFi, including passing by MRI areas?
    Or, are there people whom there bodies drain batteries?

    Just to know: I have "7 on" 16 hours shifts, I dont use any social media or video.

    I am trying my Note 10 plus with No fast charging + Night mode + power saving and for now since 7 am I reached 28% 10 pm. I will try a full day No wifi and see what happens.

    My Note 4 and 8 would barely make it to 5 pm

      Interesting science between simply plugging in to the power outlet and the mobile getting charged.

        I am happy with the 5w/1a charger that came with my 80$ device... x-x

          Spike, 25 Aug 2019I had to read all this mess because I spent yesterday looki... moreWell, I wouldn't like to contribute to another headache but don't forget that most personal cars have 12V sockets - you need to bear that in mind if you would like to charge devices which require higher voltage (doesn't apply to smartphones or at least not to many). I've read a 45 W car charger review recently, guy tried charging a Dell laptop - didn't charge at all as it required something like 15 or 20V (which the charger was capable of but the car's battery was the culprit) :P

            Nice article, very nice. At our lab here we're still discussing whether we are going to build a 45W PD3.0 PPS charger or not to target the new Samsung devices.

              Anonymous, 25 Aug 2019Yes ... It is a fact .. Let's say you work for a company... moreWhy not just super glue them to the point that it discourages the user so they end up buying a new phone model instead of a new battery?

                Thank you for this comprehensive article !

                  Conclusion, just stick with whatever charger comes in a box(unless you Apple user) and charge your phone with it. I mean I am stuck on 15W charging for like 4 years now and never complained. My phone all the time charges in about 1:30h hours fully more or less, depending on battery level. I woukd say it is reasonable time to wait and causes me know issues.

                      Whackcar, 25 Aug 2019You would expect a $1100 phone to come with the best access... moreIt's not a "best accessory". It will trash your battery and then people would say it is Samsung's fault. Smart from Samsung to not include it and then noone would be in a position to tell them anything when people start trashing their Notes with such high wattage chargers...

                        kiasunkiasi, 26 Aug 2019gone are the days where we can just share cablesNot really, it will just not be optimal, but you can charge any phone with a crap cable. It will just take longer, like, as long as before when we used to share cables.

                              Great article! Thanks GSMarena!

                                The 45W charging seems like a forced spec. The non-standard 10V is used just to lessen the heat produced from a standard 15V protocol but then the voltage delta and the amount of current being pushed on the converter inside the phone would still produce lots of heat on a tiny body of the smartphone. At that charging rate, heat is inevitable, I just wonder how long can the phone accept 45W until the power throttles due to heat.

                                As compared to other charging tech like, for example Super VOOC, which uses 10V 5A but uses proprietary charger and cable, they circumvent the heating issue by having two batteries charging in parallel inside the phone, the 10V 5A is basically distributed to two batteries at 5V5A each.

                                Charging a single battery at 5V5A is much better than charging a single battery at 5V9A in terms of heat output and battery degradation.

                                But then, Samsung's 45W might be just a 45W max charging speed. Who knows.

                                  Oppo's r17 pro is a twin battery ( this is the battery bandwidth) I'm talking about two separate batteries making up one almost 4000mah cell

                                  This get even crazier when the batter is made up of 20 smaller cell's charging in parallel with 120 watts

                                  As for ampere oppo raises amperes instead of voltage making the voltage remain unchanged
