What are your charging habits?

[j_hansen]

If phones still had removable batteries, I'd agree. But when you factor in the extra time and expense of having a repair shop replace a battery (or learn to do so yourself), now it becomes more of an issue. While batteries will degrade at different rates from person to person, it's no secret that high charges and low discharging will accelerate that wear and there's no way to know if your battery is going to be one of the good ones that hold up longer, or will be half worthless in 6 months.

That's why I said those are the general guidelines and also gave other reasons for consideration in my post. Anyone concerned about battery longevity should consider all the factors as they apply to them, and charge according to what they think is best for their situation. If I had a sealed battery (I'm still on a V20 with a removable one), I'd personally do everything I can to prolong its life. Others may not.

It can't be put more simple than that

I put it on charge every night and remove it every morning, always done that.

I've done the same since NOTE 8

But even if a 10-15% loss of capacity (as in Fig. 1 of the article) occurred in a year or two, it wouldn't require a new battery. And a possible eventual 10-15% loss would still be much better than an immediate self-imposed 60% loss iintended to avoid the 10-15% loss.

Also, as the article notes, battery technology is still improving. Some of the article's data is from 2002; most of the data has no date cited. So I have no idea how relevant it is to batteries made in 2018.

I'd personally do everything I can to prolong its life. Others may not.

Fair enough. That's why I favor advice of the form "If you do X, Y, or Z, here's what might happen" rather than "People should generally do X".

That's just the loss from one type of test, and it should be noted that none of the "new" batteries had their advertised capacity at the start. So your 10-15% loss is on top of that already reduced capacity. Running hot also degrades batteries. Holding them at a high charge level (such as overnight charging) degrades them. The number of actual cycles factors into the overall longevity. There's many variables to consider, not just if you run full 0-100% cycles, and each one of them can compound the wear and tear on it.

I once killed a battery in 6 months myself. Not by doing full cycles, but by having it plugged in constantly. That was before I started reading up on them, though.

It's okay to charge up a phone whenever you deem necessary. Everything else is hokum.

And heat kills. Samsung I think post Note 7 and with the new cooling in the 9 can be trusted some to do right. Maybe there's spare overhead like spare block pages for storage if needed.

 

[evohicks]

I charge mine from 6.15am (when I get up) to around 7am when I leave for work, no need to fast charge and if it's over 90% charged I will pull it off before this.
I have been charging it to 100% on a Friday morning for the last 2 weeks just to see how it fares over the weekend in which it gets less usage, it usually lasts me until Sunday lunch without having to top up!

 

[jnichols16]

For the past 15 years I have always charged overnight (Samsung uses smart charging to cut down to trickle when full). I also charge as needed through the day, but haven't had to with my Note 9. I have never needed to replace a battery.

Even a 25% loss would still be at the "new" level of a S9/S9+.

Told by whom? More importantly, what reason did they give, and what evidence did they cite?

The user manual certainly makes no such recommendation.

Mooncatt knows what I'm referring to and he has a repsonse above for your information...

Yes, I already replied to that.

Just enjoy the device. Charge how you want, when you want. Day, night, overnight, fast charge, slow charge, wirelessly. Whatever suits your lifestyle.

Most people won't ever have to touch the battery even if they keep the device 4-5 years or longer and thats without placing any attention on charging habits or following any norms.

 

[anon(20964)]

I never refill my battery. It refills itself magically and very safely overnight. And fairly fast at that.

 

[jlangner]

Charge when go to bed, remove when get up in a.m. I usually upgrade every year so battery not as important.

 

[Haley Chris]

If your gonna get a new phone every year or so then I wouldn't be worried how you charge it but if your gonna keep that phone for a couple years I would do the to 40 to 80 Rule

 

[CaribMas]

I always charge my phone overnight; and throughout the day at my desk and in my car. With the Note 9 I've only been charging overnight unless I have a day of extra heavy use.

 

[mumfoau]

Since I'm trying to train myself to keep devices for more than a year, I guess i could try this whole only charge up to 80% percent thing. Especially since AccuBattery has a charge alarm.

 

[Kodak2]

By the end of the day my phone is usually between 50 and 60% it then goes on charge for a couple of hours and charged to 100% and then removed from the charger, next morning after it's been on standby all night it's about 97% and used until the evening, then the cycle repeats. During car navigation using my phone is on and and off charge all day. I have never had a battery problem using it this way and the battery is usually working okay after 4 years with a drop in capacity of about 25%. My work requires me to have a good charge on my phone at all times.. The phone is a tool and needs to be used, not treated as a piece of jewellery.

 

[L0n3N1nja]

I usually charge to 100% but do my best to avoid it dropping below 25%

I also won't charge over night.

The S7 I own I didn't follow this, left it plugged in all the time while streaming video to a TV or used as a hotspot. Battery is shot, can't even get 3 hours SOT and struggles with an 8 hour work day.

I plug my phone in when I’m around a charger and I remember to. I’ve never had my phone die on me so I must be doing something right. I don’t worry about charging too much or leaving it on the charger.

 

[BlackZeppelin]

I have modified a few things about my charging habits whilst mostly maintaining the rest.

I strictly keep between 50 and 85%. It's not hard to do. I now do fast charging as standard but I do rest the phone on a steel plate on top of a heatsink and the phone is completely cool to the touch after charging.

I also have the convertible wireless charger resting on the same heatsink but have only enabled standard wireless charging-not fast. There is one thing I'd change if I could. I'd have 2 fan speeds which could be configurable in settings on the phone. So you could set if you want a fan running during wireless charging, both standard and fast, and select what fan speed.

Currently, in order to activate the fan I have to enable fast wireless charging which still produces a bit too much heat for my liking. I'd like the option of a stronger fan speed even at standard wireless charging.
