Anyone Else Trying To Keep Battery Charge To No More Than 80%?

[PsychDoc]

Everything I've read about LiIon batteries suggests that you will extend their ability to effectively hold a charge considerably by avoiding charging to anything over about 85% or letting it run down to anything below 10%.

Anyone else trying to stay in the 20% - 80% range or are you just fully charging up to 100% without any concern?

i charge usually from 15% to 100%. Is there any noticeable problem with that?

Nope. I don't have that kind of time to waste monitoring my phone battery. I've never had any issues with my batteries. I use my phone all day long and charge at night if I need to charge during the day I will as needed.

"Importantly, operating at a low voltage is good for a battery’s lifespan, increasing the number of available charging cycles before you’ll start to see a major reduction in capacity. Roughly speaking, every 0.1V decrease in cell voltage doubles the cycle life, according to Battery University. Therefore, charging up your phone in that 30 to 80 percent range keeps the voltage lower and prolongs the battery lifespan.

Furthermore, the “depth-of-discharge” has a similar effect on the total discharge cycles before battery capacity drops off. This refers to the amount the battery used up in between charges. Smaller discharges, in the region of 60 percent rather than 100 percent between refueling can double the lifespan of your battery, and only using 20 percent can double the lifetime again.

Small but regular top-ups are much better for Li-ion batteries than long full charge cycles.

Using up just 20 percent of your battery between charges isn’t going to be practical for most people, but topping up when you’ve used about half will see a notable improvement in your battery life over the long term, especially if you avoid charging up to full each time too. The bottom line is that small regular top-ups are much better for Li-ion batteries than long full charge cycles."

Li-ion does not need to be fully charged as is the case with lead acid, nor is it desirable to do so. In fact, it is better not to fully charge because a high voltage stresses the battery. Choosing a lower voltage threshold or eliminating the saturation charge altogether, prolongs battery life but this reduces the runtime. Chargers for consumer products go for maximum capacity and cannot be adjusted; extended service life is perceived less important.

I use my phone all the way until i go to bed so if it’s on 1% each time so be it...not something I care about. I Use my phone normally and don’t worry about battery long term health.

While I understand the "plug it in and forget it" mentality I think it may be important for those of us who will be using this phone for 2-3 years to consider the benefits of following the advice I've posted from experts in the field if you still want your phone to exhibit the superb battery life it now has. I know my S7 Edge deteriorated very significantly in the battery department over the three years I was using it. I, too, was one of the "just plug it in and forget it" brigade.

I think I'll at least try and respect the advice of these experts. An occasional charge to 100% here and there won't be a problem, but, in general, I'm going to try and unplug my device when it gets to between 70%-80%.

I don't worry much about the battery percentage for my smartphone. With my new S10 I charge it wirelessly at night to 100%, then pull it off the charger at 6 am and go until 7 pm before putting it back on the charging pad. With my previous smartphones I do tend to see diminished battery life after 18-24 months, but by that time I've moved on to a new phone.

I totally get your reasonings. I upgrade my phone every year so fo me there is little point in worrying about it but for those who upgrade 2- years then going these routes may work, I know my partner she upgrades every two years and her battery is enough for her even when charging each night but she isn;'t really a power user.

If you need to be that anal about your phone battery then probably should just use a flip phone! I don't understand this theory, like you I have never debated when or how long I should be charging my phone for. Just use the phone and charge it when you need to and enjoy the phone! I wirelessly charge my phone every night before bed and have never ever had any sort of battery issues on Android or iOS.

Many people have seen their battery storage capacity decline dramatically after a year or two of normal use. If you switch phones every year and this doesn't concern you, that's fine. But for those of us who plan to keep their phones for 2-3 years this is a serious issue. By the end of 2 1/2 years my S7 Edge was barely able to limp though eight hours of normal use.

Like I said, if this is OK with you then that's fine. It's not OK for me.

I would hate to have to worry about battery drain for 2-3 years. That's all I am saying. I've kept phones for 2 years and haven't had serious battery issues. Batteries and technology in general get better and better every year. The S7 edge also had horrible software and horrible lag and there wasn't the software optimization that you have now. I had the S7 for two years and the battery was NEVER good.

 

[libra89]

I can understand this concern but I don't do it. With fast charging now, it's hard to catch when it hits 80% because it gets there fast. However, I do try to avoid my phone from hitting below 39%. I kept 2 phones for more than a year each and battery life is still very good (enough for me to pass one of them on) so I feel like that has worked fine for me.

Agreed....I think this whole "how to charge your battery" topic has been beaten to death for as long as I can remember. The only thing I do is avoid letting it get to low but even that is not always possible

Same here. This may be the wrong place to be discussing this as most of us are tech enthusiasts and change our phones every 1-2 years. This isn't something we really need to worry about.

I let my phone drain pretty well, and then charge it at night or early in the morning. Otherwise why even have a large battery if you're only going to use a fraction of it's capabilities.

That's like buying an expensive sports car, and then only driving 35-50 miles per hour.

I hold on to some my phones longer , and been doing this for years and great battery life , is it correct way I'm not sure but haven't had any issues doing it . If I did I definitely be doing it another way.

I mean in theory, he's probably correct. But in daily practice, it's a little bit too stifling for me.

In theory probably, but I dont need to charge up until a day in a half on the average .

The last phone which battery gave me problems was the BlackBerry Z10...

 

[Mr Segundus]

I never keep a phone for more than 6 months so worrying about the battery is a non-issue for me.
