Help Charging with the fast charger

donmeca2020 · Sep 17, 2017

So while the note 8 came with a fast charger for regular use, how safe is it to use on regular basis? I recall with my note 4, people claim it would kill the longevity of the actual battery.

So anyone hear anything similar with the 8 ? Also we can't just pop these open and change to a new one...

heat is the #1 factor that degraded lithium. this is one reason these wireless charges have fans in them.

fast charge also happens whilst plugged up, and with the statements that fast (wired)chargers go from 0 to 40% or so in about 20 minutes (or whatever the claim is) , this method would do more to degrade these cells (no built in fan on the phone, and with phone water and air/dust tight, heat is a concern).

did that scare you?

charging a battery *period* will "kill the longevity". nature of the beast. There are websites that speak more about this if you want to get technical.

that said, use the charger as much as you want to. I have wireless chargers in the two main areas i spend most of my time and the phone always rests on one. I am not going to limit the use of the fast charge.

So then it is better off im just using my regular charger with the note 8 cord instead.... i just don't want to have the same issue i had with my note 4 and the way it was constantly dying or had to be on life support basically to just great through the day lol

There are way too many theories out there that I don't know what to believe. I've come to the point where I only charge when necessary these days, as I had my S7e on the wireless charger overnight at home, and a good portion of my day at work on my desk wireless charger, and Like yours, it seemed to become dependent on life support

I will not do that to my new Note8

You are not any better off using wired or wireless. Both will weaken batteries over time. Wireless charging is a convenience and is not necessary.

In order to use the phone it has to be charged, however, so use whatever you want that works best with you.

Lithium technology has electronic failsafes that are designed to prevent it from overcharging and being under charge/voltage due to running the device beyond the low threshold.

There are no "theories". this tech is proven and technical white papers exist that explain this charging in detail.

Again i use wireless charging any chance I can get. I have experience using wireless chargers and phones and I trust the technology.

So I've heard that you should not charge it every night, I've heard it's ok to charge it every night, I've heard to let it go almost to zero battery before you charge it, I've heard immediately disconnect when it reaches a full charge. Can't really find any recommended battery care online. What's the actual protocol?

I understand your frustration. I have no idea what to believe either.

excellent discussion on lithium and what's required to use it safely in everyday products.

batteries degrade. its fact.

in regards to the Note 8, if you want proper charging and discharging procedures, reach out to Samsung and get a direct response from them.

otherwise, you will get many opinions from people out in the wild and you will end up back to square one.

try using acubattery. It keeps track of charge cycles and monitors battery health.

Like previous Samsung flagships before it, the Galaxy Note 8 uses Samsung's Adaptive Fast Charging technology to power up the device in as little downtime as possible. There are better (faster) technologies out there, with Adaptive Fast Charging being the equivalent -- and also compatible with -- Qualcomm Quick Charge 2.0.

The difference between Samsung and Qualcomm's implementation is that AFC doesn't actually fast charge the device while the screen is on (likely some kind of safety precaution although other devices have no issue with this), so you can't actually use your phone if you want to enjoy the fast charging benefits.

So how fast does the Galaxy Note 8 charge? We timed it at 10 min intervals and here's how quickly Adaptive Fast Charging was able to juice up that 3,300mAh battery:

10 min - 13%
20 min - 26%
30 min - 38%
40 min - 50%
50 min - 61%
60 min - 70%

70 min - 78%
80 min - 88%
90 min - 96%
100 min - 99%
107 min - 100%

Total: 1hr 47min

You shave off a few minutes if it's off the whole time lol
