3 days of battery life

[boufa]

A few of you are missing something very important!

Regularly draining the battery down to 3% is going to mean s new battery every couple of months. Lithium batteries are not deep-discharge batteries. The operating range for best battery life is charge to 80% and stop. Start charging at 40% or turn the phone off.

It's great to see 6 weeks of SoT, but when you come back here in a month asking how to fix the battery not charging all the way to 100%, or discharging from 100% to 10% in just a few hours, don't waste your time - just send the phone back for a new battery. (And hope that Samsung still charges only $60 for a battery replacement.) Gone are the days when we could buy a battery for $5 and replace it in 15 seconds.

I get 3 12-hour days with light use (on a Pixel 2, which is under-batteried), going from 80% to 40%, but if I'm using the phone all day, I hit 40% late in the afternoon - less than 1 full day. And you won't do much better. A little, because the Note 9 isn't *** under-batteried, but not that much. (But I don't plan to keep having the battery replaced. Maybe after 3 years, not sooner.)

I appreciate what you are saying... though I think you are overstating it.

I have been using smart phones for many years (even before Apple invented it). I rarely run it to dead, but I always let it charge up. In all of those devices, and in all of those batteries, I have never replaced a battery or felt I should. Smartphones are designed to make your life easier and babying the battery like a mother hen ins't the point.

The best way to take care of the battery is to turn off the device and put it into a drawer... that will maximize its useful life.

Each to their own... you do it your way and I will do it my way.

This has to be one of the silliest things I have ever heard regarding battery use. I have had every major flagship starting with the original iPhone. Especially in recent years, have I never seen what you have described. Batteries can be run down. There's a reason why Samsung, Apple, nor any other major manufacturers go out of their way to warn users NOT to do this, because it has little to no effect. You would see a backlash similar to antenna gate, bend gate, if this were the case.

Dude...lol, wut? So basically what you are saying is that Note 9 users have 40% of their battery to work with - don't charge above 80% and then either charge or turn the phone OFF by 40%. Man, that gets a certified "Wut!?"

Straight nonsense...

Here's mines. Really great battery life.

The 40% to 80% routine is a great way to keep your battery healthy, but it is not necessary IMO. The amount of battery longevity you would get back is minimal to the life of the phone.

If you were to keep you phone for 5 or 10 years it might pay off, but it is a terrible way to live.

True, and let's not forget that Samsung revised the battery chemical structure/makeup starting with the note 8, reducing battery degradation significantly. I think the note 9 has the same type of battery as well.

Just no

They are saying the Samsung Note 9 has a stellar battery.
Think it's made on the U.S. and not China.

What is a stellar battery.

I have never done this. I have always charged when it hits around 15 to 20% and charge it fully to 100%. I have not had a problem with my battery life fading or needed to be replaced.

 

[ClintRo]

It would be very hard to kill a Lithium battery in a month...LOL

Buy the Samsung upright charger and charge it 100 %.
Stop worrying about it.

You get any instructions telling you to only charge it to 80%,
I posted by a book that sells for ,9.95
On Amazon that is like 485 pages, telling you everything about the note 9.
My buddy told me about how great of a book it was.
You got the book right next to your phone.
You can do things step by step.
But seems people thinks it's too expensive to pay 9.99 to learn about a 1000.00 phone.

 

[cardboard60]

I let my battery get down to 89% and I stick it on the charger and charge bit to 100 %.
It don't have memory.
Think y'all worry too, much about a 4000ah battery.

The Geek Squad at Best Buy will do this for you.

Actually he made that battery replacement look way too easy. I struggle with a screen protector let alone a battery! Good video!

 

[cardboard60]

I have watched these guys use a gitaur pick and suction cups and micro screw drivers taking the super small screws out and putting them in a small container.
The screws will hit the floor and you will never see them again.
And I'm a retired locksmith, safe man.
I'd rather get off the money and pay somebody that does it everyday to do it.
Once the back cover or screen is removed. You lost yer water protection.
Unless somebody knows how and what glue to put back on it.

Pixel stand looks fake don't it.

It says it will mean a new battery every few months! Too funny. I charge my phone when it gets down to 5% and then charge it to 100%. My Note 8 still gives me two days on one charge and was purchased on launch day.

No one has time to keep their battery between 30-70% and todays don't need that. Charge your battery as you want and you will not hurt it.

I never knew people really invested so much time into when is the appropriate time to charge a phone. That's too much work.lol

You guys forget we have 2 other battery saving modes that if in a pinch and no charger even at 25% will save you until you find one or next day and it's happened to me . So I never worry about note 9 or my s9+ when I'm out and about while others bring power bank with them.

I think it's apps like Accubattery that contribute to this "charge it up to 80%" mentality. Frankly, I personally don't even think about what scientific evidence may point to this. All I know is that if it was making a difference - the chances of it making a material difference before I trade or sell the phone is minimal.... and I bet that goes the same for most of you, too.
