20 watt and 30 watt chargers seem to charge at the same speed

[PaulQ]

Here a comparison between my 24w RavPower PD car charger and the new 46w PPS charger I picked up

I'm curious - how long after you plugged it in did you take this screenshot? I am finding I get the high numbers soon after I plug in but they drop by roughly half about 30-60 seconds later (2100mA or so) and continue at that level. My phone had 28-35% battery level.

Not long, I waited for them to stop climbing, then when they had very little fluctuation I took the screen shot

So it's maxed at 22w? That's fine with me. With my P6 I usually use the 18w charger that came with my P5a. It charges plenty fast for me. My 25w Samsung charger is a bit faster up to about 80%, then slows WAY down. Takes about an hour to go from 80% to 100%.

I'm sure this will become the brouhaha-of-the-day for the Pixel 6. Maybe the bad press will spur Google to work on it and perhaps fix it in an upcoming patch.

Personally, I don't really care, since I'm not interested in ultra-fast charging. But I can see why many people would want it.

Well, that explains it. Probably explains why I just plugged it into my 65-watt PD/PPS charger at 35% and it's charging at 900 mA (might be the temp affecting it though). I like the phone so much, I'll accept it. I usually don't need super-fast charging but there were a couple of times where it helped with my S21+.

Thanks for sharing that, helped.

The Anker 45W Nano II (foldable) charging adapter fast charges the Pixel 6 Pro.

So does an 18w charger.

A slow charging brick will charge the phone faster than a super fast brick, unless you keep the battery temperature below about 95 or 96 degrees F. The tortoise and the hare.

An 18W charger is not going to reach the 30W charging rate for the Pixel 6 Pro. You need to use an Anker charger and then post the results. It's like a night and day difference.

It's like me using my 10W Pixel Stand vs my 15W Anker wireless charger. There is a difference.

The Pixel 6 Pro doesn't actually charge at 30w. Google was on the BS like always lol. You can get like 22W at most and there's only 10 min difference between their charger and an 18W charger. Don't waste your money on a 30W unless you just already have one.

The Pixel 6 series won't charge at 30w. Tests have shown that they max at 22w. My 25w charger will charge it slightly faster than my 18w.

I read the same article as you. They didn't test the 45W Anker charger did they? They used 30W and 18W Pixel chargers. What are you talking about?

I myself tested with 18w, 25w, and 45w. It takes about an hour to charge from 80% to 100% no matter which brick I use.

This makes sense if you are referring to total charge time from a low battery level. From https://batteryuniversity.com/article/bu-409-charging-lithium-ion

Increasing the charge current does not hasten the full-charge state by much. Although the battery reaches the voltage peak quicker, the saturation charge will take longer accordingly. With higher current, Stage 1 is shorter but the saturation during Stage 2 will take longer. A high current charge will, however, quickly fill the battery to about 70 percent.

If you are only skiing partial charges, then you'll see the most benefit. If you are charging to 100%, especially if already at a higher charge state, the difference is negligible at best. If starting at around 70%, the charge controller is beginning at the second stage, resulting in no change at all due to reduced charging currents.

 

[GoNavy79]

I don't see the point in this conversation if you didn't use the Anker 45W foldable Nano II charger adapter that cost me $35. I don't care which 45W charger you used. If it's not the same one I have then our conversation is moot.

Agreed.

I agree, it doesn't make sense to invest in Google's latest fast charger when you'll realize all of a 10 minute difference in charging time from 0-100% vs the 18w chargers shipped with prior Pixels.

But if you're going to decry this as evidence of Google's "BS," consider this:

The max deliverable current of a charger isn't always matched to what a device can pull from it, and Google never said it was. Take for example the iPhone 13 Pro Max, which peaks out at 27w when used with their 30w charger (which, by the way, they sell for $49, about twice the price Google charges for its 30w charger). And let's layer onto that the single piece that Google did say about their charging speed, which was that it charges to 50% with their 30w charger in 30 minutes. Even with a 23% faster peak rate of charging, and a 13% smaller capacity it has to charge, it still takes the iPhone 13 Pro Max just as long to charge that first 50% (though it does do the 2nd 50% much faster, and certainly delivers a lot more SOT on a charge - but of course, they just might decide again to throttle your phones performance to 'preserve' that battery as it ages).

Everyone seems to have blinders on with regards to other OEMs doing something they could nitpick about until Google does the exact same thing, and then opens up an arsenal of criticism as if they're the only party who could ever do something so 'awful'...

I did buy the new charger but after looking at battery charging stats and battery life I'm okay with what the charger delivers. Slow and steady preserves the battery life and will let the phones battery last longer in the long run.

Others are offering faster charging that will deplete the batteries long term effectivity. I'm not down with that.

At best it's disingenuous, at worst it's false advertising.

Intentionally or not, they deceived customers. That isn't good from any angle.

It's especially bad given it coincides with not including a charger for "environmental reasons"... Makes it look like a very poor taste cash-grab.

Then why buy a 30Watt charger at all?

As a light user, I generally keep my battery between 50% and 95%. After reading this thread, I'm glad I didn't buy G's 30w charger as I don't think it would offer me any benefit over the 18w that I already have.

I have an 18w, 25w, and a 45w. The 18w is plenty fast enough for me. The 25 is slightly faster, and the 45 is same as 25.
