Charging question - Samsung Galaxy Note 20 Ultra Questions & Answers

Hi Guys,
What is the best practice to charge our Note 20 to maintain good battery life?
I checked my charge cycle and it shows its 8 so far but I only have the phone for a few days now. And I guess 8 is not good as it says on Internet the battery life cycle is 400-500 charge cycles. So I want to avoid battery damage.
With this in mind:
1. Do we need to wait for phone to completely shut down because of battery and then recharge? Or its not good for the battery?
2. If the answer to previous question is "no" then when exactly we need to charge the battery to maintain good battery health? If, for example, the phone is on 30% and we recharge, how is it different from phone being on 80% and we recharge battery life-wise? And how this affects charge cycle and health?
3. Can we charge the phone as often as we want despite the battery level?
4. Can we leave the phone charged at all times (100%)
Just want to make sure I am using the most efficient method. Don't want my battery to die in a few months time.
Thanks!

Just change it whenever you want. No matter how you take care of the battery. With today's battery technology, you need a replacement after 2 years.

Best practice is never run your phone or any battery powered device past 25%. I know it's easy to do since we are on our device pretty much all day. Reason for this is because when charging the battery it needs to have resistance to charge correctly. Less resistance the less charge is given there for weakening the battery life and quality. I charge mine every night no matter what. Ive been doing this with all my Samsung phones and never had any issues. And last its OK to run the ballery down once a month to clean out old or bad charge voltage left behind.

Best to charge between 30-80%
Li's love small frequent charges ie 40 to 65%
As the cell voltage climbs so does the damage; try to avoid going above 80%.
Charging battery below 80° F can cause LI plating which permanently degrades the cell; try to avoid. Never charge when below freezing.
Try to avoid going over 100° F
High temperatures and battery voltage cause the most damage.
Between 5-20% has the lowest power density of the voltage curve, try to avoid using that range.
If discharged to 5%, recharge within a few days. If the cell voltage drops too low it will be useless. Generally this would take 2 months or more but don't chance it.
Use the 25 watt brick to charge, enable fast charging.

What is a charge cycle?

A Li-ion battery has a limited numer of charge cycles, but what constitutes a charge cycle? According to some people a charge cycle is used every time the charger is connected. Another opinion is that only a charge from 0 - 100% consumes one charge cycle. So how is it really? If the first assumption is true then one should only charge when the battery is almost emty. If the other one is true then it's ok to charge at any time.

A charge cycle is the process of charging a rechargeable battery and discharging it as required into a load. The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge.
Apple Inc. clarifies that a charge cycle means using all the battery's capacity, but not necessarily by full charge and discharge; e.g., using half the charge of a fully charged battery, charging it, and then using the same amount of charge again count as a single charge cycle. -Wikipedia

Ok, but that means that charging the battery a lot instead of waiting until it's almost completely drained, shortens its lifespan.
Ideally, a Lithium based battery is "healthiest" at or about mid level. A full charge cycle is technically not 0-100%, as these batteries (at least in consumer electronics) have circuitry built-in to prevent overcharging, overdischarging, and shorts. Overdischarging can cause what's called runaway discharge, where it'll keep discharging even if not connected to anything or the device is turned off. Heat, possible fire, and even explosion. Those Dell and Sony laptops that were catching fire several years ago? That was because the protection circuitry was faulty. And why you should always buy OEM factory batteries, or ones made by reputable companies like Zerolemon or Anker, and not cheap Chinese knockoffs. Hobbiests (flashlights, R/C equipment) often use unprotected batteries since they can get a bit more capacity out of them, but this is dangerous and requires monitoring and judgement.
So the answer is a charge cycle is from 0-100% and back down to 0% (or the opposite; charged, discharged, then charged - depending on your point of view), where 0% is the point where the circuitry within the battery and/or the device itself cuts the power.
There is no need to "condition" lithium rechargeable batteries (ie: fully drain them, don't use until fully charged, etc); this is a holdover from the days of nickel-cadmium (Ni-Cad) batteries, which did require conditioning for optimal performance.
The main destroyer of a lithium battery really isn't even the charge/discharging of it, but rather the heat associated with it. For example, one can keep a battery charging and charged at 95-100% while playing an intense game, downloading a large file, or running a wi-fi hotspot, but this sill quickly destroy the battery, even there's no actual "cycle" happening. The ~500 charge cycle figure assumes a typical usage of training and charging. The reason a battery is "healthiest" at mid levels is that this is where there's the least heat being generated.
Yeah, I have kind of adapted to the thought that charging whenever doesn't impact the battery in a negative way. So if my charge is 80% and I'm going out for the day, I still charge it to full 100%. If however (as the first answer suggests) this consumes an extra cycle then it would be best not to charge it. In the past this didn't matter so much but with many phones these days it's hard or even impossible for the user to replace the battery. This makes the answer to my question more important...

80-100% is not a cycle, it's 20% of a cycle. However, it is the worst part of the cycle (higher voltages, more heat). Ideally, for the battery's health and longevity over the months/years, it'd be best to keep it between, say, 30-70%. But this is impractical, potentially impossible for some, and, frankly, dangerous.
That's why I'll only buy phones with replaceable batteries. Either instantly, or without terrible difficulty when the battery hits that ~500 cycle mark. I have 3 phones: A Galaxy S4 (with a couple spares, including a 7800mAh Anker), a Nexus 4, which I've replaced the battery on, and a OnePlus One, which I know I can replace if/when I need to. I'll never get something like a S6 or Note5 or iPhone where battery replacement is nigh-impossible.

Yeah, it's very annoying that not batteries on all cell phones are user replaceable. And we can exchange them on some phones anyway with a little trouble, but as you write it's completely impossible with some. I put in the charge if my battery is 50% or something and I'm going out later. This should consume only half a a cycle and it's practical for me.
I now charge when the battery is like 75% before I'm going out. Is this ok or should I let the battery drain and then charge? The latter I did for a long time with a phone I had, and the battery had great performance until I sold it.

Charging Battery

What's the consensus on when to charge and how long?
Is it safe to charge the S7 battery overnight, even if only around 50%? Or is it better to wait until your almost dead?
One of the I.T. guys at work was saying you should wait until you're below 20%, then always charge to 100%.
Just charge it whenever you want, this isn't the 90's or 2010. You'll probably replace your phone before you start to see it majorly affecting your battery.
You'll get a very slight improvement in overall battery life if you keep the charge between 25% and 75%. But we're talking very small. But yes, it's perfectly safe to charge your phone over night. The battery / phone / charger electronics won't overcharge the battery.
What you do want to avoid is draining the battery down to zero, or close to it. If at all possible, don't let the charge drop below 20 - 25% on a regular basis.

Thanks for the info. I thought it was beneficial to charge all the way to full?

Lithium Ion batteries are different than older technologies, such as NiCad and NiMH. These batteries suffered from the "memory effect" (although not as badly as most people thought), so it was good to charge those fully. If you always charged them to, say 80%, they would eventually only take an 80% charge. Li batteries don't suffer from a memory effect, so you don't need to worry about that.
The other thing is that Li batteries hate three things: excessive heat, being fully drained, and being overcharged. Tesla stops charging when the battery pack reaches 75% of full charge, and displays that as a full charge. Similarly, they consider a 25% charge as "empty." Then again, a Tesla battery pack costs something like 10,000 bucks, so it's important to as much as possible to maximize the life of the pack.

Wrap charge

I apologize in advance if it's was already asked
So i'm wondering how it works. Does it use warp charge till it reach 100% or it goes normal like at 50 or 70%?
I noticed it's slow 90 to 100 whereas i see warp charge logo
I'm on havoc so idk if it's the same, but havoc shows the output, from what I can see its between 5-6amps until 50% and slowly tapers down from there to 1 amp between 90-100%

Never charge to 100%, it shortens the battery lifespan a lot. It's best to use it on 20-80 charge range.
After 80% the charging speed slows down like any other phone.

The about 20/80 has also worked out well for me on all my devices...

This is a fallacy. I charge my phone to 100% everytime and after a years time my battery still has 93-96% capacity. The damage is done if you let it discharge below 10 or 15%. Lithium ion batteries looked to be charged more frequently and when the battery is above 75%. The higher the battery percentage the more charge cycles it will have.
Thanks for the lifespan tip. Didn't know about it

I didn't understand the last part of your post, if you charge till 80% you'll use very little charge cycle. The most of the battery wear is done on the last 20% charging. Even if you store a li-ion battery at 100% it get damaged very quickly.
They like to be charged often and stay on 40-50% average charge level. If you do that the battery is going to last 3+ years.
If you charge overnight to 100% and top up every time you'll need to replace the battery in less than 1 year.

This is not the case. Charging the phone more then 20 or 25% or more results in more charge cycles. Look up BatteryUniversity.com and it will explain it to you. The damage above 80% is done if the charging per doesn't reduce and you charge to quickly from 80-100%. This is why the battery reduces charging speed after 80% down to a trickle charger from 95% to 100%. This is built into the charging tech so there is no battery damage charging your phone to 100%.
I charge my phone to 100% everyday and something twice in a day and never have battery issues or reduced battery capacity. My phone lasts as well after 1 year as from the day it's purchased.

Read carefully, it says exactly what I'm telling you.
I'll attach a screenshot of the website that you suggested, it's shows what I'm saying that if you charge to 80% instead of 100% you get three times more battery cycles of lifespan (850-1500 vs 350-500).
Also the second screenshot shows that if the battery stays at 100% it degrades much faster (only 80% capacity after one year vs 96% capacity if stored at 40%).

And if you charge routinely from 75% or higher, you can achieve up to 1200 cycles for lithium ion batteries. I'll do my way as I don't lose battery capacity after a years time. This is info from battery University. Been doing this for years (since the note 3). Again I'll say, it's not charging to 100% it's if your charge to quickly from 80% to 100% it's what's bad for the battery.

If you read what you posted it's the temperature During the charging that reduces the charge cycles. There is no heat in a OnePlus phone with Warp or Dash charging. Depth of discharge also increases cycles if you charge when the battery had more charge. For example... Charging at 25% or less gives 250-300 charge cycles, 25-50% gives 350-500 cycles, 50-75% 600-900 cycles and above 75% up to 1200 cycles. I'll continue to follow that by battery University and continue to have a battery that doesn't lose capacity

I'm not going to convince you but I don't like the pread of disinformation.
If you read the graph in the picture it show that what damages the battery is both from high temperature and high charge level. Just look at 25 degree row:
40% charge - >96% capacity after 1 year
100% charge - >80% capacity after 1 year
Things are even worse at 40 degree: 85% capacity vs 65% so 20% extra battery capacity lost.
Remember that when the battery capacity is at 80% means the battery is gone because it cannot cope with the ampere under load and the phone will shut down. This after 1 year without taking consideration of the extra damage while charging to 100%.
Now I'll copy and paste that part from the website:
Most Li-ions charge to 4.20V/cell, and every reduction in peak charge voltage of 0.10V/cell is said to double the cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.0V/cell should deliver 1,200–2,000 and 3.90V/cell should provide 2,400–4,000 cycles.
4.20v is 100% charge
4v is 70-75% charge
Be careful that's tge voltage of the cell, not the charging voltage.
I agree with you that slow charging makes less damage but still charging from 75% to 100% makes hugely more damage to the battery than charging from 20% to 80%.

Yeah I can say the same about disinformation which is what I said to you to begin with. My op6 which I bought and had since launch still gives me 9-11 hours is screen on time today like it did on day one. That phone like all the rest of my phone is charged to 100% every day, normally from about 70% or higher remaining battery when put on charge. Using a few different apps my battery capacity still shoes 95% capacity.
Again, charging to 100% and damaging your battery is a fallacy. Charging to 80% is fine but your depth of discharge is greater putting more stress on a lithium ion battery.

That's is from lab test made from scientist, so I trust it.
Also no one tells you that you need to wait 20% to charge, you can do 40 to 60 or 30 to 50 but i can assure you that I've got a phone a xiaomi mi 5s 3 years old same battery charging 20% to 80% and is still usable, I'm using it as a second phone.
My previous phone was a galaxy note, I was charging it overnight and charging it to 100% often through the day, i replaced the battery three times in two years.
Thats my experience.

So guys what you recommend for charging pattern for best battery health ? I'm rly lost from what u said...
Me I charge my phone every night with very small charger I think it's 1amper maybe lower.
I never let it under 25-20 % and always charge it full with zero heat and takes long time to charge because of the charger.
If I wake up to go toilet and night and it's charged I removed it and that's it..

The best charging pattern is to always keep the battery near 50% and do frequent charges through the day.
Don't charge overnight, leave the battery at around 50% when you go to sleep.
At the morning, when you wake up plug in the warp charger so you can charge to 80% before going to work.
Charge over 80% only in special circumstances when you need long battery life.
Try to never go below 20%.

I recommend you to plug your phone 1h before sleep and charge it fully or do it in the morning. You may increase your battery life with all that slower charging, up to 80% etc but really? Is it worth to resign from that cool Warp charging feature just for extending your battery lifespan and you won't even know how much it will extend? And you can even exchange the battery at authorised center for about 20 bucks.
I thought the myth about leaving the phone charging overnight breaks stuff was explained away already. There's stuff that runs in the background that improves the usability of the phone and decreases battery drain.
Read this monster post for full info. Not so much looking after the battery but system optimization. Warning. It's a big read. I've been leaving my phone charging overnight for years. I still have a OP5 that's being used daily and still gets fairly impressive SOT. Other thing is, "we" tend to change our phones quite often. SO I just don't worry about it too much and use the phone the way I want to use it.

Question Poll: do you use the 85% charge limit?

Do you use the 85% charge limit?
i personally think that 85% is BS i have had god knows how many phone all charged to 100% every single night and ZERO! issue. and limiting this phone specially to 85 is a big cut in the hours you will get.
Not a chance. I'd hate this phone if it only charged to 85%.
I Use it all the time. 85% is enough Juice for one workday and i simple want the battery to last as long as possible. I have had bad experience with batteries dying after ~3 years.
The 85% Rule is no BS. You also have to keep an eye on minimal SOC and never go under 10% to avoid unnecessary battery degradation. With that your battery will perform according to the specs (~700 cycles until 80% SOH, modern smartphone batteries). Otherwise it will suffer and that reduces cycle life. This is simply the state of current lithium battery tech.
From my pov, a full day usage requires 100% of charge because some of them cannot charge the phone while they are outside the whole day.
I have wireless chargers almost everywhere, so when my phone is not being used it's normally sitting on a charger. That means that it very rarely uses much charge, so charging to 85% is fine by me. If I knew that I was going to be away from a charger for a protracted period, then I'd probably charge to 100% beforehand.
I can't get too excited about battery management. If I need to buy a new battery for my phone at some point in the future (it has never happened yet...) then that's what I'll do.
i use 85% because i have quick carger in my car and it charge all the time.
at home I have wireless charger and when i need i put it.
I tried it for a few weeks and instead of having 80% leaving work I was at 50%, not really worth it since I'll probably have a new phone in six months. It was too much of a headache stressing about battery life without the phone fully charging.
No, I charged to 100%.

Question 85% VS 100% - and why?

I have always charged my phones to 100%, this 85% thing is very new to me.
I've never heard about it before until I saw it in my S22 ULTRA.
What are the benefits of charging only to 85%? Does it last as much as with 100%?
Does it really recommended to charge it up to 85%? Im not an heavy user, but also I'm not changing my phone once a year, I'm changing it one time in 3-4 years.
Also, I tried to never charge my phone at night, and trying to catch the battery not lower than 10-15 percent to charge.
So basically, it bothers me a little bit in the eye to see that the phone is only about 85%, because that way basically the battery will run out much faster(significantly, yesterday 10% went down in 45 minutes, which means I'll lose 45 minutes from battery usage for nothing).
So, my question is, is it really worth it? Is there a significant difference between the two options? I'd love your help, thank you all!
The 85% is to protect and prolong the battery life. I agree that you will loose 15% of battery time if not charging to 100%. I charge to 100% and when battery is 10 - 15 I charge to full. I guess on the long run it's better for the battery to only charge to 85%, but I change phones every year or 2, so I'm not to worried about prolonging the battery life
Set low limit at 30-40%
Top limit of 72-85% is better.
Li's love frequent midrange power cycling.
Start charge temperature is important to prevent Li plating. Battery should be at least at 72F, 82-90F is better. Cool if charging temperature goes above 99F. Never charge in direct sunlight.
Never attempt to charge at 40F or lower
Avoid having the screen on while changing.
When using, turn phone off if battery temperature reaches 100F or cool it.
Replacing the battery isn't a big deal unless you don't do it on a timely basis. When an Li has reached 80% of it's original capacity it's reached the end of it's useful service life and is degraded.
Degraded Li's are more likely to fail which can heavily damage the phone. Any swelling is a failure replace immediately.
High voltage , temperature and current drain stress the battery. Other than avoiding low temperature charging and going to either low/high extreme voltage ranges constantly I wouldn't worry about it too much.
I now replace my heavily used Note 10+ battery every year or so to avoid another failure, routine maintenance. Batteries are cheap and relatively easy to replace.

So, I understand that it recommended to charge up to 85%? :-D
I searched on google to buy a S22 ultra battery that will keep in home until I need it, but couldn't find one.

If you can last to bedtime on an 85% charge then fine use that setting if you intend to keep the device for 3 years or longer.
If (like me) you need 100% charge to get through the day, continue charging to 100% and dont worry.
I have been using mobile phones for 25 years and I charge overnight as I sleep. I have NEVER had a battery failure or problems.
Life is short, enjoy your new phone
P.S. If you are worried about stressing the battery by charging to 100%, I suggest you also disable Fast-Charging as that is WORSE for a battery cell than 100% vs 85% iMHO.
I used to charge my Note 10+ to 100%, every day plug it while in my car or plug it to my laptop now and then. After 2 years of use battery health was 89%.
On my Lenovo laptop I stop charging at 60% as suggested by Lenovo vantage. Bull****. Battery lasts a lot less after one year. Almost the half.
Enjoy your gadgets and mobiles. Anyway after 2 years most of us get a new one.

how does one set low limit?
i have a smart plug i use for my charger, only on long enough to charge phone from 20% to 85% (battery setting limit enabled).
i usually charge at 30% to 85%.

I just do it by eye. It's not rocket science.
Accubattery lets you set an alarm if you want.

Keeping a spare isn't a good plan as Li's start to degrade as soon as assembled. So after a year or more of sitting there it will have lost some of its initial capacity.
They should became easier in the future.
Any solution to modify the protect level?
"protect battery level 90%, 95% mod instead of 85%"
85% seem to be very short time of using
For anybody wanting to change the limit from 85% to lets say 90%, you can use the App called Galaxy Max Hz, you can find it on this forum : https://forum.xda-developers.com/t/...ods-qs-tiles-tasker-support-and-more.4404929/
One of the options is to change the battery charge limit, on the lock screen it will still say : "Charging stopped at 85%" even though the battery is at 90% as set in Galaxy Max Hz

85% is actually rather on the high side. Either correct the excessive battery drain or replace the battery. When an Li reaches 80% of its original capacity it's reached the end of its usable service life. It's degraded at that point. Degraded Li's are much more likely to fail. Any battery swelling is a failure.

Actually, the protection level should be 80% or less to maximize the battery’s useful life.

I use the 60% protection on my Lenovo as they suggested and gess what, after 8 years my battery still works fine, and lasts for 2h/3h. I used my laptop every workday on heavy use, and it's the most cheap line, it cost me 300€ in 2015 (Lenovo G50-30 Celeron N2840). It's all day pluged, but when i need to use on battery it's fine!
So i realy think this battery protection works, and my S22 Ultra it's for last at least 5 years, and the 85% it's enough to run my workday.

Maybe. Depends on usage. On my N10+ which is heavily used with frequent charge cycling from 40-60% to 72 to 85% most times I get about 2 years out of a battery. Higher battery temperature shortens the lifespan as well. Fast charging is more stressful as is using the device right after a fast charge. High current drain while in use is also stressful; optimize the device to increase SOT and battery lifespan.
Frequent partial charge power cycling can extent the typical 200 full charge cycles to 800 or more. A partial charge is not a full charge cycle.
Start charge temperature matters.
It's an electrochemical reaction, heat is required for it to charge properly!
-//-
Never attempt to charge if near freezing
Fast charging will not engage if battery temperature is below about 55F to protect the battery.
Charging below 72F or above 103F can cause Li plating which will permanently degrade the cell.
Optimum start temperature is 82-90F, cutoff is 100-102F max. Cool if needed.
Regardless of service time replace the Li when it reaches 80% of its original capacity. At 80% it's reached the end of its service life and is considered degraded. Degraded Li's are more likely to fail
Any swelling is a failure and it can destroy the device. Battery replacement isn't hard or expensive. Just part of routine maintenance...

Here is a good article why it's recommended to not load the batt to 100%
How to maximize battery life: Charging habits and other tips
If you've ever wondered what the best way to charge your battery is, here are some scientifically proven tips for maximizing battery life.
www.androidauthority.com
Personally i just keep the load between 65% and around 20-30%. Only if i know that i will leave the house longer than 4 hours I do a 85% load or 100% if i want to film and take photos. But this rarely happens.
