Hello Guys, i bought a new mugen akku and dunno what´s the best way to calibrate it.
There are a few things that are confusing me:
1.Mugen Instructions: "Never drain battery to 0%"
(but that´s required for calibration, isn´t it?)
2.the battery got its full power after a few charges/discharges
(so would it be better to wait to calibrate the akku when it got its full power?)
So finally, should i wait with calibration or do it at the beginning? I think one time is necessary to let it go down to 0%.
So what are your advice?
thx in advance, l-viz
The way I calibrate mine is to discharge it completely so it turns off by itself (normally happens around 1 or 2%) then plug it into the charger and let it charge completely to 100%. Note that the LED will turn green at 90% .. so its not done yet!
Just my 2 coppers...

You are just calibrating the battery meter on the phone, not the battery. People constantly abuse the terminology.
You don't need to drain the battery to zero, because the battery meter is not even remotely that accurate in the best of circumstances. Draining to 10 or even 20% is no different than draining to zero.
What CAN happen if you drain to zero, is you you may trip the safety circuit on the battery, and render the battery unable to take a charge, thereby rendering it useless. Its not very likely, and safeguards on the phone are designed to prevent this, but plenty of people on here have had it happen. Full power cycles (draining to zero) also shortens the long term life of the battery. Especially considering there is NO value added to draining the battery to zero, there is no point it doing so intentionally, and taking an unnecessary risk.
Just charge your battery to 100%, let it sit on the charger for a while after full, to make sure its really topped off. Then use the phone until 10-20%. Repeat this a couple times. You can also go into recovery and clear battery stats before you charge/discharge. But I haven't noticed this to make much of a difference.

Draining the battery to a literal 0% is almost impossible. Lithium ion batteries do not allow devices to utilize all the juice in a the battery. Once a device shuts off and tell you the battery is "dead", there's actually a bit more juice that is only used by the battery to prevent the battery's level from becoming too low.
Think of it like space partitions in hard drives. While you can use 100% of a single partition in a hard drive. There will still be space left over in the other partition.
Now what mugen means is to not allow the battery to reach the 0% of the ENTIRE battery. In order to make that happen you would have to discharge the battery until your device doesn't turn on and then NOT charge the battery for a very long period of time. I'm talking weeks and months of no charge whatsoever. Other than that, feel free to allow your phone to die and charge it back up. This in conjuction with deleting your battery stats file will speed up the calibration process.
Hope I helped out.

What is supposed to happen with the failsafes on the device and what ACTUALLY happens unfortunately are not one and the same. There have been plenty of people here that have let their batteries drain to zero, and then the battery will no longer take a charge.
True, the battery is not actually zero voltage. But its low enough that the safety circuit on the battery will prevent it from accepting a charge. The phone is SUPPOSED to prevent the voltage from dipping that low, but it doesn't always work. So the only way to bring the battery back to life, is with a special battery meter with a "boost" function. Since the vast majority of us do not have access to such a thing, the battery is effectively dead, as buying one is likely cheaper and easier than getting access to such a battery meter.
As I've already mentioned, this is unlikely to happen. But its happened to at least a few people with our phone, and I've seen it happen to other XDA users with other devices. No point in playing probabilities, if it happens to you, it sucks and it doesn't matter how "almost impossible" its supposed to be. As I already discussed, the battery meters on phones are not even close to accurate enough to read single, or even 5% battery increments. So draining to zero is not any more beneficial than draining to 10%. No benefit in draining to zero, so why risk it?
I have learned the hard way that discharging lithium ion batteries below 20% is the fastest way to kill them early! (greatly shorten their life)
thanks 4 replies, a lot of useful knowledge
Hi all-
As you all probably know Li-ion batteries do lose some capacity over time. And the more charge/discharge cycles they go through, the more they lose. However, this loss of battery health or longevity can be lessened by reducing the number of full charge/discharge cycles, by not charging all the way up, and also by not maintaining the battery at full charge for long periods of time.
For example, my Lenovo laptop has some smart charging software that only charges the battery to 60%. As I am normally using the laptop with the AC adapter, this helps preserve the battery, as keeping it up at 100% isn't the best thing for overall longevity. But if I know that I will be away from AC power for a while, I can switch the mode and it will charge all the way up to give me full capacity.
My question is this: does any such software exist for Andriod? I've looked around but not found anything. I am a fairly light user, and most of the time I am near AC power, so I wouldn't mind having my phone battery only charge to 60% percent or so. Ideally the software would have dual modes like on my laptop, one for preserving battery lifespan, and one to give full capacity on the days that I need it.
Any suggestions? Or does this not exist? Or are there hardware limitations of which I am not aware?
Phones tend to have longer battery life then laptops so as long as you have apps like DS battery saver, Greenify and Carat among other apps you will be able to get the most out of your phone.

I think you misundetstood my question. I'm not asking about battery life (i.e. how much talk time or screen on time per single charge). I'm asking about battery health or life SPAN (i.e. I get 4 hours of screen on time now, but what about a year from now? Will I only get 2 hours because the battery health has declined due to over 300 charge/discharge cycles?).
All batteries lose capacity over time. Is there software that helps prevent this by limiting charge?
No there isn't. I don't see the point of having that kind of software on a phone as by the time that happens you will be eligible for an upgrade.
We had what you're talking about for the gnex. Called battery life extender. I don't know if this is available on the sg3 kernel wise.

Thanks for the replies!
Battery technology may be good enough at this point to have good health until the next upgrade, so you make a good point. Personally, I don't care about the latest and greatest (and I'm a broke student) so I only upgrade when I absolutely have to. I'd probably still have my Droid X if it hadn't died.
And thanks for the Gnex info. I've heard they are notorious for poor battery performance. Seems like there's nothing for the GS3, but it's good to know that it is a possibility on at least some phones and that the devs have worked on it.

that is true. the affect is probably minimal though(like we probably lose .7% of our battery per month if dont let it get low before charging it, instead of the typical 1% per month)
i get through half of my day with about 50% battery less, sometimes more. so i've made it a habit of charging it once i see it's around this 50% mark.

Here is the good thing though... These phone's minimum operating voltage is higher than the minimum voltage of a Li ION battery. Using standard battery life measurements, the 0% according to the phone, is about 20% of standard.
Should you do a full discharge every now and then in order to calibrate the battery? I haven't been able to find a definitive answer on this in other related threads. Some say you should, some say it's not necessary since the battery doesn't have memory cells. I have never let my battery get below 50% and everything seems to work fine but it does seem to make sense to do a full discharge from time to time so the battery knows its capacity.

Li-ON battery's do not need to be calibrated. that was only with old battery tech such as Ni-Cad or NIMH
I let mine get low all the time I use my phone a lot. Hopefully its not to expensive to replace battery since Google thinks that replacing a battery is to complicated for us tech savvy people
Justice for Kelly Thomas RIP
I don't worry about it. I charge it overnight. If I've over used it in the day and I feel it will die before bed, i'll top it up but not to protect the battery. Just to ensure I can use my phone.
If they wanted you to do anything special with charging / draining, it would be in the instructions

The battery itself does not but occasionally the controller needs a kick in the pants. Deep drains on li-ion should be avoided at all costs. The phone hasn't been out long enough to even think about the sort of problem. But after a couple hundred charges you might see a behavior that will be corrected by one full discharge.
Its not uncommon to see cases where you actually replace the cell behind a controller and the controller not picking up the change in capacity. Never in cell phones mostly laptop battery rebuilds etc but it exhibits an idea of what happens. The battery controller takes note of the original, current maximum and current charge capacity. Not sure how I suppose voltage versus read amp hours. But as a battery gets old you might start seeing the maximum capacity reading fluctuate. But if at any time the actual chemical capacity is higher than the controller thinks it is the controller will prevent the battery from reaching its potential.
Used to have older PSP batteries reach 100% real quick, quick fix was to deep discharge through the controller using a small light bulb. The battery would then take a significant charge and last a few more months before kicking the bucket.

40% is a good number for storage, its actually better to store it at 40% than 100%. Actual use 20 to 25% is my personal range but I would say just never let it get below 15%. Lithium Ion does not mind being topped off. Deep discharged will ruin it real quick. My laptop battery lasted 3 years never letting it go below 25%, murdered a cell phone battery once a year letting it die.
I let it go to 1% and turn itself off. Then I charge it back up. But if I know I am going out in the next few hours I charge it as much as I can before I leave.

Its not any different. as with older battery technologies they would loose capacity until they are calibrated 0% to 100% this is due to the chemistry of the battery
LI-ON battery's have a different chemistry which allows them to store greater capacity without loss like NI-CAD and NIMH did this is why you turn off your phone for a week and turn it on you find it still has about the same battery percentage as you turned it off before.
here's an example of a NI-CAD battery which needs to be calibrated.
You have a drill you haven't used for 3 days it was fully charged before you put it away if you take that same drill 3 days later you'd find it dead. where as LI-ON battery's would still be alive and full capacity. if you charge it from there it wouldn't be calibrated. as calibration requires you to drain the battery 2 times or more till it reaches it full capacity and charge it back up to 100% and repeat.
If you were to do that with a LI-ON battery you're basically doing nothing but wasting your charge cycles on the battery and you could kill it as LI-ON battery's DO NOT LIKE TO BE EMPTY
Because of all that NI-CAD and NIMH mess mostly all power tools you'd find in a shop such as home depot are now equipped with LI-ON battery's as they don't require calibration and can be left for months and it would still have its initial capacity prior to charging because Ni-cad battery's suffer from a memory effect and LI-ON does not, NI-CAD Requires full discharge before recharge LI-ON does not you get the point here right? LI-ON is better!
Now for those apps that claim calibrate the battery they do nothing they just Improve the reading of the software in android to get the battery percentage which is reset every time the battery charges to 100% so in short don't calibrate your battery

The battery controller is still the source of the problem. If the batteries chemical capacity at a given moment is 1800 mah down from its original 2300 and the charge controller thinks the capacity is 500 the controller will only charge the battery to 500. Most controllers do not act like their dumber counter parts which will trickle or cut off when the cells characteristics indicate it is reaching a full charge.
The controller in these batteries while varying greatly in design all have one thing in common. They are designed for safety. The controller will actually stop accepting a charge forever if the voltage of the cell goes below a certain point. It will also never charge it above the current observed maximum capacity no matter what reality is.
You can poll a battery using vendor specific commands to get the designed, current maximum and current charge. The current maximum charge capacity is a changing value it will change over the life of the battery. This was an aging laptop battery that while the controller knew what the "Full Charge Capacity" was currently it decided not to report that to windows resulting in a hilarious 410%.
But we are talking about a problem that really won't rear its head for 1 or 2 years and were talking about doing it once or twice over the life of the battery. People doing it now and all the time WILL kill the battery very quickly for no benefit.

look man
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

now believe what you want
Once in a while isn't explicit. The video posted earlier says once a year or so... both of those are "a while" to me
It all depends on the controller and the software but mostly its no longer necessary.

Fair enough.
But still doens't seem like a good practice given how the recommendations with this kind of tecnology are usually don't go too low and try to charge at different values, not always plug the charger at the same level.
Li Ion batteries charge to a maximum voltage before the charge stops in a phone or other device that charges while also operating.
To fully charge a Li Ion battery you need to monitor current draw of the battery as it is charging, it drops as the cell reaches saturation. This is difficult to do in an operating circuit... Though the tech may be getting better, as load sharing was not common for charging cell phones a few years ago, but it may now be, I have actually been looking for info on powered device charging, but find little beyond load sharing type.
So the battery in a phone could hold more juice if it was charged out of the device, and more still if the phones could run at the 3v minimum of Li Ion. (min voltage of arm devices is around 3.5v) Load sharing chargers can charge fully though.
Also charge rate affects battery life... slower charging is better for long lifespan. If you overnight charge, use the lowest rated charger you have, or standard USB charging. The current phones come with higher amp chargers now... It really doesn't speed up the overall charge cycle to 100% very much, but it does make charging to 80% quicker. So you can do a quick charge of a low battery to a usable level in a hurry.
Power tools use LiFe chemistry batteries which are more tolerant of abuse and misuse... at the cost of less voltage and capacity and more weight.
I work from home so it's easy for me to top off the phone as needed. I'll usually throw it on the charger for a while around 3-ish PM to make sure that I have a full charge going into the evening since I do a lot of reading on it after the kids are in bed. I'm definitely what you would call an opportunistic charger - there's no need to drain the battery all the way unless you absolutely can't get to a charger. I don't understand why people choose to run their batteries down all the way when they don't have to.
I still currently own a Samsung galaxy s3, and I have been charging it to full 100% and letting it drain fully until it shuts off. Once i get S8+, should i still be doing this or will that mess up the battery over time. Do you guys drain until 10% , and charge up too 90%? Was curious.
Batteries have so many charge cycles at a certain depth of discharge. My understanding is you get more charge cycles if you discharge less.
So, unlike removable battery phones, I plan on leaving this phone on a charger as much as possible and usingbt the battery when necessary.
The battery change on this device looks hairy!

I See, does the phone stop from overcharging the battery once you reach 100%?
It's best to keep it between 20%-80%
Also, pretty much all lithium ions are nearly impossible to overcharge.
You generally want to keep your batteries between 40-80% I believe is the sweet spot. I will not let my battery go below 30% generally and I top it off whenever available. Forgot where I read it but as others have said your phone has so many charge cycles (500 or so before the battery starts losing a certain compacity). And if you constantly charge from 0-100% each time, you are using a full charge cycle. Instead if you charge it at 50%, you would be using half a cycle, etc.
Someone can correct me if I'm wrong.
Sent from my SM-G955U using XDA-Developers Legacy app
Ive read similar things. I generally follow this and try to charge before i reach 20% up til 89%.
Ive also read somewhere to deplete battery to 0 atleast every few months if not sooner. Dont know if its true though.
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.

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.

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.

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.

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.

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...

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!

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.
