Galaxy Note 10+ 45W charger doesn’t seem to offer much over 25W

According to a battery test performed by Thai tech blog DroidSans, the 45W Super Fast charger for the Galaxy Note 10+ might not be worth your investment. The difference in recharge speed between 25W and 45W is not as great as one would’ve thought, judging by these results. It’s a rather negligible 4% difference between 25W and 45W charging by the time the Note 10+ hits 100% battery on the latter. And even if that final 4% might require up to an additional ~8 minutes to be covered by the 25W charger, it still doesn’t seem like much of a performance gain.

That is if we take into account another earlier test comparing the Note 10+ 25W charging speeds with other smartphones. It suggests that it takes around 1 hour and 5 minutes for the phone to gain a full charge; that is, with the phones turned on (the screens were off). Meanwhile, the recent test performed by DroidSans indicates that the device reaches 100% battery charge on the 45W charger in around 57 minutes (with the phones turned off), so virtually, the time gained by using the 45W charger for a full recharge shouldn’t be greater than ~8 minutes.

The difference is a bit more noticeable at the 30-minute mark

Of note is that the gap between 25W and 45W charging is a bit wider at the 30-minute mark, with the 45W optional accessory delivering 73% battery charge, and the 25W one covering 67% of the 4,300mAh battery within the same timeframe.

We weren’t able to test the 45W Super Fast charger ourselves, but on 25W, our Galaxy Note 10+ review unit went from 5% to 60% in 30 minutes with the device turned on and the screen turned off.

The 45W Super Fast charger doesn’t ship with the Galaxy Note 10+. It’s being sold separately for $50, and it’s not available for purchase in every market. Then again, you might not lose much by not being able to buy it in your region, as these early tests don’t show a lot of promise. Would you buy the 45W optional accessory for your Note 10+ after seeing these preliminary test results?

So, let me get this straight. You haven’t been able to test the charger yourself. But by playing around with the numbers and reviews (mixed together from MULTIPLE OTHER SOURCES) you have determined that the charging speed gained with the 45W charger is only slightly faster than with a 25W charge?
Figures don’t lie, but liars figure!
This is pure ‘Click Bait’!!!!
Let us know when you can actually CONFIRM your findings and not mish-mash together half tested theories from other Sources!!

what about fast charge wehn screen is on?

A huge disappointment! Why charge extra 50$ for only 8min?

Edit: something looks weird, how the note 10 (not the + model) is on 48% after 30min and the note 10+ is on 67% while the first has much smaller battery cap?

Good to know! A battery can only take so much stress anyway so personally I did not expect to see a 40 minute full charge, but let’s look at that number. A 4300mah battery charged from 0 – 100% in less than one hour. That in itself is very impressive. It doesn’t necessarily mean it’s doing any favours for your long term battery health though. If you intend to keep the device for longer than 2 years, I’d try to charge it overnight while sleeping and stick to standard low speed charging. What’s the hurry? The phone will last all… Read more »

did you ever broken your battery in phone?

I have never had a phone for more than 2 years, but batteries lose capacity after a number of charges and fast charging produces more heat and stress. I just got my Note10 plus this morning and after the first full charge I will be charging at night at standard speed. I don’t have any reason to fast charge it. Batteries don’t normally break in a phone, they just wear out, quickly or slowly depending on the number of charges or power of the charge.

IN POWER setting you can enable and disable fast and super fast charging ?

I could imagine that they bring an update improving the charging since the charger is not officially available yet. Difference is far to small.

Not everything is a software issue.

i think this would be the case, as they are probably fine tuning what’s safe or not.

I tried charging my phone with a 61w charger from Apple MacBook pro, but turns out it’s only different by 3% compared to charging from a Adaptive fast charge power bank (15w). Both phones started out with the same battery % and all apps closed.
