Note 4: Do you keep fast charging on?

[bassplayrguy]

I do the same. They really must not want us to take the back cover off. Actually I had a grand idea and don't put the cover on at all. I have a clear case so it looks like the back cover is clear.

I bet that looks pretty cool! Pics?

Re: Do you keep fast charging on?

Yes Samsung put it through testing. Is that why they made it so you can turn it off?

If you are worried about it, turn it off. I leave mine on all the time and have no issues. If the battery does get damaged, I have an extra and know where more are.

I switched to my Otterbox now haha or I would definitely give some pics.

I realize this is a 2 week old thread, but I wanted to chime in, as I know a little about the technology. The technology was created explicitly as a way of charging batteries more quickly WITHOUT damaging the battery any quicker than normal, as the energy density of batteries has reached somewhat of a plateau. So no, I will not be turning it off, as its very concept is the antithesis of what many are worried about.

Sometimes I don't even know why I should care (base on my history) knowing that I will sell it in 4-6 months but I do and only use this feature only when I need it.

I just don't see the point. The technology was created purely as a way of increasing charge speed WITHOUT damaging the phone any quicker than normal(all batteries incur damage with normal use). Why is anyone worried about it harming their battery? A lot of people creating an issue that doesn't exist. Seriously, if you just take 5 minutes to Google "Adaptive Fast Charging" you will see within a few minutes that you are wasting your time unnecessarily. Not ranting at you, just the hundreds of people on here who would rather turn it off and create a huge forum discussion about it without ever once actually talking the time to research the technology. You would have already saved a significant amount of time if you had just researched it in the first place rather than come here to discuss it, NOT research it at all, and turn it off anyways. It's just hilarious to me. Lol.

Agree totally; so many threads on this board fall into that same category...

 

[BarfingMonkey]

How do you know it's not causing ANY damage?

 

[wase4711]

why would you "assume" it is???

 

[BarfingMonkey]

Cause there is an option to disable it.

There are lots of great articles that explain Qualcomm's Quick Charge 2.0 technology. NONE that I've read (and I've read a few), indicate ANY issues with using this technology. There is intelligent electronics inside the Note 4 to decide what charging voltages and current to use. The phone is DESIGNED for this technology. I even suspect that this technology is SAFER for the battery, since the integrated electronics monitors the charging process - but that's only my opinion.

Personally, I can see no reason NOT to use it - but, to each their own.

For reference, here are a few articles:

Cause there is an option to disable it.

It is quite possible it is a placebo for all of the people convinced that there is a possibility of harming the battery.

The circuitry built into these batteries prevents overcharging/overdischarging during normal use anyway--regardless of the presence of the fast charge/discharge.

It isn't the amount of current applied to these batteries to recharge them that is the "threat" to them (the wall chargers we get with the phones are not powerful enough to deliver "too much" current to the batteries).

The biggest threats to life expectancy on these batteries is temperature extremes (don't leave it in a hot car in the summer or a cold car in the winter) and discharging the batteries below a certain voltage level.

Common sense and reasonable care will prevent the former, the circuitry inside the battery prevents the latter.

It is possible, potentially, that there is a small amount of increase in heat to the battery during fast charge. (More current=more energy, which certainly gives the possibility of more heat) but it is most likely well within the normal operating temps. If it isn't the difference is so small that I doubt anyone can tell the difference without measuring equipment. You certainly won't be able to measure a difference in service life.

I can also disable wifi, bluetooth, mobile data, screen rotation, location services, and TONS of other options. None of this means it is harming your device to enable it. Like I said, the technology was created as a way of charging faster WITHOUT any additional damage. The circuitry specifically monitors for damage, and reduces speed if any is detected. Researching technology and actually understanding it really helps to not be unnecessarily afraid of new technology. It seriously only took me about 10 minutes to learn all of this.

That doesn't really mean anything.. .

Not the same

I'm just looking at it from an engineering prospective.

 

[LaTuFu]

Well, strictly from an engineering perspective, the batteries are overengineered.

It may be more accurate to say that the operating range of the batteries that is set by the circuitry has plenty of safety buffer built into it. In other words, there is very likely plenty of voltage left in the cells when our phones say "0 battery" that could safely operate the phone and not harm the battery, but the manufacturers keep a safe buffer to prevent catastrophic damage to the batteries, phones, or people.

Just saying you said because there is an option to turn it off .. that means it could hurt the battery... But phones do have a lot of options to turn off so that doesn't really fit.

Honestly anything can hurt your battery ... using your phone will hurt your battery over time. Fast charging may cause the battery to degrade a little quicker over time but I don't see it shortening the time a ton .. even if it did you could just nab a new one and slap it in .

I am also an engineer. Please explain your PERspective. I don't understand how you are looking at it from an engineering perspective if these chargers were engineered specifically to prevent damage...

Yea. Regular usage damages batteries. That's why all batteries eventually need to be replaced. They engineered these chargers specifically to prevent any more damage than normal charging. So many unnecessarily paranoid people here. Lol.
