Effects of fast charging

[Kevin OQuinn]

Trickles when needed, the excess powers the phone...

You see the phone is being powered by the charger, the drain on the battery is zero, so it doesn't discharge...

I'm not sure it's that simple. The juice has to go through the battery, or at the very least, the battery has to be supplying some juice all the time and then get topped up as needed. And that seems to be, in general, not great behavior for the battery.

It can vary from device to device of course.

It also seems like there is a severe lack of recent data on the newest gen batteries and charging tech. I actually wish Samsung would have went more into that in their presentation about the Note 7 but I understand that wasn't the point of what they were doing.

Actually no, once the battery is fully charged, it is bypassed and the charger powers the phone directly... It's why the phone is cool when removing it from the charger in the morning... (Unless, if course the phone is not "sleeping" for some reason... IE background data or an app running all night... In that case it might be a bit warm.

Bottom line, there is no issue with leaving the phone on a fast wireless charger overnight...

This is not accurate.

The phone is cool when it's fully charged because it's....not charging fast. It has nothing to do with the battery being "off".

You can't bypass the battery entirely. If that happened then unplugging the device would cause it to shut off. I don't have a newer phone that has a removable battery, but the G3 will not power on without the battery inserted. So the battery is not "bypassed" at least in that case.

Fine. I'm out.

Battery quality degrades while being at 100% charged for long periods of time anyways. So even if you are accurate about this bypassing battery theory (and you're not), it's still bad practice.

 

[clrdust]

It sure does thanks

The nearly unanimous consensus of the entire spectrum of lithium battery creators and associated industries?

I've decided to never charge my phone again because I don't want to wreck my phone. I've got it on Ultra Power Saving and I've put it away in a drawer so I don't get the urge to use it because we know that using your phone has the potential to wreck it. I'll check on the phone once a day and if it has no power I'll have no choice but to get a new phone and start the cycle again. This phone business is sure hard on the wallet.

The problem is that you leave it on. Turn it off and boot it up once a week to check if it has any life left. When you're done, turn it off.

If you are using a certified Quick Charge 3.0 charger with a compatible device, there should be no damage to your device. Quick Charge 3.0 ha a new feature called INOV (Intelligent Negotiation for Optimum Voltage), which allows for a better power output and a more optimized charging cycle by dynamically adjusting the charging voltage over the battery charging cycle. However, if you just use a Rapid charger that you by from the side of the street then yes that may cause damage.

With regards to the Qi Charging. Many Qi chargers today have maximum output of 5V/1A which will charge a Galaxy S7 from 9% to 100% in about five hours. BUT with the new Qi Fast charger, your Galaxy S7 can be charged from 9% to 100% in just over two hours.

So even if you use the Fast Qi charger, its still going to be slower than your normal Quick Charge 3.0 cable alternatives. So i wouldn't worry at all about any sort of damage to you phone. I use a standard non quick charge, charger for my Blackberry PRIV which has an output of 1,300 mA and the Qi wireless charger has 1,000 mA.

So, the Quick Charge 2.0 that the Edge uses needs the 3.0 charger to benefit from the INOV update?
Disregard, I see the INOV feature isn't available on the 2.0 that the Edge uses

There are plenty of sources and studies for this. Please research these studies and let us know if you're still unconvinced.

It trickle charges when 100%

 

[ToddK]

Sure, fine. I stand by my statement.

...And sleep soundly every night as my phone charges.

Yes it was a smart-*** move and I am sorry about that. Please accept my apology.

But here are the problems....

1) Yes Fast Charging will heat up the battery and cause it to degrade faster. How much faster than a 1A charger? IDK.

PROBLEM - Over 13 million S7 edges are in the hands of customers. The box comes with a quick charger only. So either Samsung is knowingly bundling an accessory that wears out the device faster, ensuring the owner will then upgrade every year to the new shiny thing, or it is safe to use. Which is it?

2) Yes keeping the charge at 100% for prolonged periods will degrade the battery. Degrade it more than discharging from 80% to 40% a few times a day? IDK.

PROBLEM - People, in general, charge their stuff overnight. And this is a mobile device, so going on your way with 100% charge is ideal for a true road warrior. And personal experience says keeping it at 100% does not significantly degrade the battery (I had an iPhone 6s+ 1.5 years old and with keeping it on charger the battery still had 92% capacity when I gave it to a family member).

3) Sealed Batteries and "thin is in" like on the S6 and S7 lines have created the need for fast charging, and has let grown men wear skin tight jeans, and these men have no time to wait 5 hours for a charge, because they take 2.5 hours to squeeze one leg into their pants.

PROBLEM - See number 1

I agree with all three of these observations and don't know the answer to whether or not fast charging is actually worse or if staying at 100 is always worse, that's a study that to my knowledge hasn't been publicly published. Here's the thing though - on the 100% vs 80,40 whatever - my typical advice to people is, "try to do shallow discharges if you can, but if it's not practical, it is better to charge it to 100% and then go than it is to let it die from not enough juice. By a lot. Even if that means leaving it on the charger overnight".
