    The free bundle that I ordered after the pre-release will be complete tomorrow when the 45w charger arrives...I look forward to seeing how fast the 10 plus hits 100% after a full days use.

    flossy Carter did a comparison in a video yesterday and it hit 100% from 0% in like 50mins and just over an he for 25w

    I was eagerly awaiting his video. I will spend that $50 elsewhere. In fact, that's just what I need to get a Galaxy Tab A with my credit...

    Basically the difference was about 10%. I think I'll stick with the 25W charger.

    Samsung should improve charging speeds on the 45w charger....not much difference between 25w and 45w....maybe with software update...it can charge at least in 40 mins to full charge would be awesome

    If you charge your phone once every day, you'll save yourself close to 4 days in charging time per year.

    it charges a lot faster when the phone is almost dead. I cant tell a difference when its 50% or so however. just my observations, I haven't timed it or done a real test though.

    I just ordered it, it was in backorder but Note 10 plus 5G should be waiting for me when I get back from holiday next Friday so I'll be using the 25w for a week or two before it arrives, should give a good idea of how big the difference is, I'm to curious to not get the 45w and I saved over a hundred quid on the phone so why not

    I believe it's more important from say %1 to 70 percent not 100%..plenty of times we on vacation and just got time to shower and get desssed and leave back out... Bout 30 mins could get me to like 70% I'm cool with that

    This exactly is the situation this charger is for. I always wireless charge but their may once in a blue moon where I need a quick charge and don't have time.

    45 minutes from 0 to full charge would be a 1.33C charge, which would probably destroy the battery on the first charge. The battery is 4.3 Amps, so you can't charge it at more than 4.3 Amps and, since charging isn't 100% power transfer (nothing is), it takes over 1 hour from 0% to 100%. (No matter which lithium battery we're talking about, no matter which carrier, no matter what power in the battery. It's physics, and the fact that lithium batteries can't be charged at greater than their current rating.)

    But discharging the battery to 0 kills it quickly, the best operating range is 45%-100%. Since the battery gets warmer as the charge in the battery goes up, it usually only fast charges to 70%, so it's only fast charging for the first 25% of the time (to a 70% charge, then it drops back to normal charge, to keep the phone from becoming a Note 7. It's still going to take normal charge time for the last 30% of the charge, even if they could charge it from 45% to 70% in a few seconds (which would leave tiny pieces of phone embedded in the walls).

    Bottom line - the reason they can't speed charging up much more is the laws of physics.


    I believe it's more important from say %1 to 70 percent not 100%.
    1. Discharging it to 1% regularly will mean a battery replacement is in your very near future.

    2. It doesn't fast charge from 70% to 100% as it is. If you charge it starting at 70%, no matter which charger you're using, the phone is only asking the charger for a normal charge.

    Agreed,

    Problem is a lot of consumers don't understand the C rate of charge. Most of the people I know who are familiar are engineers or people who operate RC vehicles and Helicopters.

    In any event unless you always drop your device to zero the time it takes to charge a device isn't that significant. Even from zero whether its 50 minutes or a bit over an hour does it really impact anyone's life?

    Of course we will get those that keep a phone no more than a year who don't care if they kill a battery.

    If you try hard you can kill a brand new battery in a month, so they should.

    Not understanding how a phone works may not be as dangerous as not understanding how a car works (except for not understanding drum brakes back in the day, driving through a flooded area, then slamming the brakes on when a kid darts out in front of you), but the problem is still the user, not the thing being used.

    Mine came in this morning. Probably the first time in my life I've gotten a package at 8 AM on a Saturday.

    This thing is pretty fast. I probably wouldn't have paid $50 for it given how fast the included charger is, but I will almost definitely use this thing as my after-the-gym and travel charger.

    I grabbed the Galaxy Tab A 32 gig 2017 model from Sam with my 150.00 credit. It originally was 200.00.
    Caught it with a 40% off deal and Bam I only paid 9 bucks for it.
    It's the 8" one
    Plus it's updated to pie and One UI 1.1

    Really a hellava deal. And I don't like tablets.
    But needed it for the cameras in my home.
    Just a suggestion.

    That's deadly for 9 quid, even if you are not really a tablet person it'll come in handy when flying etc.
    Pair it with an Anker Soundcore BT speaker (24 hour battery) and you have a great portable stereo too

    I definitely agree with the general sentiment here. My research has shown me that these lithium batteries are most optimal between 40 and 80 percent. While I am not completely sold on it, the app AccuBattery does provide much useful information.

    You said that fast charging stops at 70%. I have always seen the rate slow down once it reaches 80%, not 70%. Either way, the batteries like to remain between 40 and 80 and are considered to be safest (least volatile) between those percentages. This is why they are always shipped with around 50 or 60% charge.

    Above 80% and below 25% they are considered to be in extreme operating regions. AccuBattery also provides estimates of battery wear based on your charging session. For example, I went from 20% to 57% and the app said the battery wear was just 0.05 cycles (5% of a full 0-100 cycle) even though I charged the battery 37%. As you get closer and go above 80%, that wear estimate goes up drastically. Going all the way to 100% increases the wear significantly. So, as I try to explain to my wife, leaving your battery plugged in overnight AND always charging to 100% are two of the worst things you can do for your battery...at least when it comes to how long the battery will last over the long term. You probably would have to keep the phone for about 18 months to really see degradation, but I know people who have seen changes in their batteries after about a year. Those are the same people that charge to 100% and leave the phone plugged in overnight. So, if you upgrade your phone every year, this is likely to matter very little to you.

    Another observation, when below 20 or 25%, and when at 100%, I have noticed that the battery drops faster than when it is in the more optimal range.

    Addressing only your last paragraph.

    The device is measuring a voltage drop and percentages are not really linear.

    I have been using the 45w charger to quickly pump up the battery from say 65% to 85, in less than 30 minutes. That's convenient, but have not used it for regular charging. I have to think that hard charges all the time can't be good for long term battery health.

    Have you tested the same amount using the 25w charger? I was considering getting a 45w charger, but the 25w is so fast I was not sure there would be much benefit.
