hi!
guys, when should i charge the Galaxy S battery to maximize his life?
In my old phone, i only charge it when the phone shuts down himself. It can run for 7 days with no problems until i need to charge again.
Should i do the same thing with Galaxy S battery?
Well, when i need to connect the phone to the PC using USB cable, it will charge anyway. Is it bad? Should i do it only when i know the battery needs to be charged (when it has low battery)?
any time you want
it should always be topped up, there is no memory effect
Some people say that we should charge when the phone has 25% or 30% of the battery. And every month we should make a complete charge and discharge.
Is this a good method to keep the battery ok?
best way is to cycle through 2 or 3 batteries
charge them full
then use them down until you get the warning, and change to new battery pack, then take the used battery to the charger

Although I don't really have any definite sources to back this up, I've read several places that Li-Ion and Li-Polymer batteries can (and even should) be charged as often as possible. You should avoid letting them run flat, apparently.
What is certain though, is that they themselves have no memory effect like NiCd and NiMh batteries have.
our SGS will nag you to death as soon as it reaches 10%, and it will constantly annoys you to charge the battery at 5%
so, no worry about running flat
Technically to maximize the life (ie. capacity) of a Li-ion battery you should charge to full when it gets down to 40%.
The cooler the ambient temperature the better - A Li-ion battery operating at 25 degrees C will lose 20% of its capacity in one year. Higher temperatures drastically increase this degradation.
Given that most people will move to a newer phone after 2 years or so, and spare batteries are cheap as chips, it doesn't make a whole lot of difference.
So, people say that we should charge the battery when it has 30-40% of the capacity.
But what is the thechnical explanation?
Sent from my GT-I9000 using XDA App
that's exactly what i would like to know as well at 30%-40% will make the battery totally useless if that is true
might as well take the phone with a super long extension cold with you if that were true
LMAO

I don't think that would be the best strategy, AFAIK (and read)
Li-ion packs prefer more frequent charges, even if after partial discharges, than full charge-discharge cycles.
Its also not good to store the pack fully charged. Best to store at 40% charge.
Following these 2 concepts, I imagine its better to charge the battery as often as possible, like every day, than to let it discharge until you get the warning.
Also, if you cycle through several packs, letting each one discharge almost completely, then charge it fully and move to a different pack like you suggested, that means you will be letting the battery unused at full charge for a longer period (the more packages you use, the longer the pack will stay stored at full charge).
Thats how I understand the behavior of those batteries. Just my 2 cents.

I will say what the first reply said, charge as often as you feel you have time. Do not wait for any percentage of drain. There is no memory effect and yes about once a month do one full uninterrupted cycle. The point of which is to let the device's power management recalibrate where 0 (or thereabouts and 100% of the current fill are.
Cooler is better, this is also true.
All educated advice on Li-Ion batteries is that they remain healthier for longer the fuller they are, but the chemicals must be exercised occasionally, thus the full charge cycle in one go.
One charge cycle also actually counts over multiple charges, and not just uninterrupted ones. You can drain then charge 25% 4 times and that is counted as one cycle for these batteries.
I have always stuck to this advice since I learnt of it several years back and I find my batteries work better and longer than many people I know (who stick with drain, charge methods (lack of updated information).
i agree with nailerr
Simply charge it when you need to. It's better to have a fully charged battery when you need it, than run out of battery when an important call is coming through
So, the main reason to charge it with 30%-40% left is to avoid the battery heat too much?
I found this: h**p://batterycare.net/en/guide.html
It says more or less what you guys said here.
But you need to know that i always charge from 0% to 100% my old phone. It is 4 years old and it has no problems with the battery. It can run up to 7 days without any charge... Looks like charge it that way is not so bad anyway i guess...
I've been following the great battery impression thread, which discusses ways to tweak the Nexus 4 settings, ROMs, and so forth for maximum run time between charging. This thread focuses on a different battery concern.
The Nexus 4 lithium polymer battery is sealed, and as far as I know, there are still several unknowns about replacing it. We've seen a tear-down showing how to remove the battery. However, as of now, few users have attempted it and there's not a consensus about how easy or difficult it is to do. Questions include:
Even with the correct tools, are the tabs that secure the Nexus 4's back prone to breakage, potentially leaving the case borked?
Is the battery difficult to extricate from its compartment?
Will it a high quality replacement battery become available inexpensively on eBay and elsewhere, or is it this battery, which was not designed to be user-replaceable, too much of an oddball for that to happen meaning that a replacement battery will be expensive and hard to find?
That said, the ease (or lack thereof) of replacing the Nexus 4's battery isn't what I've come here to discuss.
Given the unknowns about battery replacement, my concern is to how to maximize the Nexus 4 battery charge cycles and reduce the capacity drop of the battery over time. It could be bad if after just a year, the Nexus 4's capacity is already noticeably dropping. Not possible? I'm not so sure. Based on what I've read, it may depend upon how we handle charging.
This article at "Battery University" discusses the discharge characteristics of Lithium batteries, and it is my understanding that Lithium Polymer batteries, like the one in the Nexus 4 mirror these characteristics.
My takeaway from the article is:
Charging the Nexus 4 battery before it drops to less than 50% capacity will greatly increase the number of charge cycles before there's a noticeable capacity drop. Letting the battery nearly completely discharge will greatly reduce the number of charge cycles, and therefore greatly reduce the time before battery replacement will be necessary. (Table 2)
Inductive (wireless) charging, while convenient, generates extra heat that will over time reduce the recoverable capacity of the battery. (Table 3)
Having read this article, I am curious about the charging characteristics of the Nexus 4 and which, if any, charging variables we can control as users to maximize battery longevity.
When I first get a new smartphone I try to do a handful of full cycle charges before doing any partial charges. Your battery is still "new" and in the "break in" period. Many users that were the first to get theirs have reported their battery life as getting better. Of course a lot to do with battery are things like your data usage and what you have syncing.

Thanks, but I will again clarify that that I created this thread to discuss maximizing the Nexus 4 battery's long-term life and recoverable capacity, not maximizing run-down time in the short-term. That is already being discussed extensively in the great battery impression thread.
I have had a lot of experience with LiIon batteries over the years and I can tell you that the enemy of them is both inactivity and deep discharge use.
Use your phone as you normally would, but avoid frequent deep discharges. Don't be afraid about the number of charge cycles. Frequent charges are better than deep discharge cycles.
These pups have been designed to be used the way most folks use frequently used rechargeable devices. Pop it on the charger when you can, even if you know it won't be there long enough to be topped off. The more frequent and varied activity the better.
I'll add that I do not currently see an LG BL-T5 Nexus 4 replacement battery sold anywhere.
FYI - The Nexus 4 uses an 800 cycle battery as well so makes it even less of a thing to worry about. My SGS2 still gives me good battery life and it's more than 1yr old already, and i think that is a 300 cycle battery. Remember also that at that 800 cycle mark the battery should still have 80% of it's original capacity. 800 cycles is more than 2yrs of constant use/charge every night and for people that don't so much that could put you in the 3yr-4yr range. If you still have this phone 4yrs from now, i think you wont need to complain if it "only" has 80% of it's original charge.

There is little point in worrying about charging before it's discharged to 50% and/or not charging to maximum. Yes it increases the number of cycles, but is reducing runtime between those cycles, so you have to charge it twice as often using up the extra cycles gained, so overall it tends to even out.
The longevity argument for only partial discharges really only applies at the time of design and specification where the manufacturer can spec a larger battery and sacrifice some of the capacity (by only charging say from 30 to 70%) to get extra charge cycles. Clearly with a mobile phone this isn't desirable to do, as we crave all the the runtime we can get in the smallest form factor possible.

Is the "800 cycle" rating is based on real world usage, or a set of idealized laboratory conditions that few users will actually meet? Many Nexus 4 forum users are reporting running down their batteries to a discharge depth exceeding 90% on a daily basis before recharging. This will dramatically reduce their battery's number of charge cycles. The "800 cycle" rating is only useful if we know the conditions upon which it was tested.

Point taken, although it looks to me like the relationship between discharge depth and maximum number of charge cycles is not linear. From the way I read it, frequent deep discharging can markedly impact battery longevity which is why I'm skeptical of the 800 cycle figure. Given that many Nexus 4 users are currently reporting an inability to make it through a full day without completely draining their battery, those particular users are bound to have shortened battery longevity unless they charge at least twice/day.

Yes it isn't linear, but the advantages are also outweighed by the negatives, such as having to plug it in more often to charge, and if people are struggling to get through the day now on a full charge/discharge cycle.....
The 800 cycle figure is probably about right for chemistry used in the LG Nexus, and most of us will have replaced our phone in a couple of years anyway long before we start to notice the lowered battery life.
The other thing with a lithium batteries is they are like perishable foods, even if we don't use them much, after a few years the capacity has diminished anyway. So even if we only charged the phone twice in two years, the third charge capacity would probably not be that much different to having charged it every day for two years.
So we shouldn't worry about the battery, the best thing we can do is use it as much as possible as it is going to degrade anyway, and we will see little benefit from treating it with kit gloves.
The above also assumes the battery can never be replaced. It certainly is replaceable by the manufacturer or a repair centre, and more than likely most of us could manage a replacement ourselves.

Phil
One very important thing to realize is that these 500/800 or whatever hundred cycles it's talking about is not how many times it can be charged, period.
It's not like after the 500th or 800th charge, this battery can never be powered on again.
Read the article closely:
" the number of discharge/charge cycles Li-ion can deliver at various DoD levels before the battery capacity drops to 70 percent."
Also, if you lower the voltage of the charge, it seems battery long term life greatly increases:
"Most Li-ions are charged to 4.20V/cell and every reduction of 0.10V/cell is said to double 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; 4.00V/cell should deliver 1,200–2,000 and 3.90V/cell 2,400–4,000 cycles. Table 4 summarizes these results. The values are estimate and depend on the type of li-ion-ion battery."

When a lithium battery is fully discharged, it isn't actually completely discharged. LG like other manufacturers will have programmed a level that shows 0% on the phone before it shuts down, but in reality this might still leave 10% or 20% or 2% capacity in reserve, we don't know the figure, but presumably LG have set both full and empty charge points to ensure we see around 800 cycles.

Yes you get more cycles, but because you have a battery with reduced capacity, you are having to charge it more. Overall the benefit isn't as great as the numbers make it. If LG wanted to give us 1600 cycles they could lower the charge voltages, but then the battery capacity would have to be advertised at around 1050mAh, meaning it lasts half the time it does now, and will need charging around twice as often.
For a mobile phone with a typical 2 year life span, the priority is to maximum the time between charges while ensuring the battery lasts the typical 2 years of most peoples phone contracts. It isn't a co-incidence that 800 charges works out as a bit over 2 years if you charge every day.
We don't need to worry about the battery, just enjoy using the phone. Also the battery doesn't just stop working at 800 cycles either, it just doesn't hold as much charge, but capacity is lost anyway over time regardless if you use it or not as lithium batteries start to age the moment they are made.

A lot of assumptions there, Phil.
My "priorities" and LG's differ. 2 years from now, some will replace their Nexus 4 with whatever shiny new phone comes along that offers holographic video projection chat and does double duty as a sex robot. However, I will happily trudge on with my Nexus 4 for between 3 to 5 years which is how long I typically own a phone before replacement. I don't need bleeding edge, especially if the bleeding edge is a menstruating sex robot phone. Just sayin'.
We don't know if the Nexus 4 battery replacement will turn out to be either very costly and/or difficult. For those of us who don't plan to toss our Nexus 4 into a landfill two years from now, it pays to know what measures we can take to prolong battery longevity.

Hmmmm....how did that happen...
I don't know if we will really know how good the battery longevity is in this thing until the device is a year old or more. Lithium polymer technology varies a lot. There have been a lot of advances with this tech in the last few years and some companies claim to have developed manufacturing techniques that allow THOUSANDS of charge before noticeable drops in batty capacity. Other technologies developed include the tech Apple uses and advertised in its MacBook line a few years ago that claimed longer battery life and very fast charging compared to Lithium Ion batteries. It all varies. LG claims to have some special tech baked into this battery that allows it to charge to a higher voltage compared to batteries of similar size, but I don't know how long its life is rated at.

Hi guys, good afternoon, how are you?
As I was looking after the Nexus 5 and the battery life of the device began to get discussed, I was unaware of the fact that nowadays we can just charge the device however we like, using Lithium-ion polymer batteries, different from the past, when a full recharge was recommended for the battery performance not get affected.
Considering that, for some users the battery life shouldn't be a concern, mainly for those who have a power outlet nearby, making an option to recharge it at any % level before getting it to fully recharge during the night.
I'd like to know from you guys: how do you recharge your devices? Do you wait for it to drain every % of the battery before recharging it or just plug it on the power outlet whenever needed?
Also, do you guys believe that recharging it at any % level does not affect battery performance?
Thanks a lot!
Modern batteries have a finite number of charging cycles before they being to lose performance. Generally speaking, 100%-0% is one discharge cycle, so if you want to maximize battery longevity you should do your best to minimize the number of discharge cycles you subject the battery to. It is not strictly speaking a direct relationship, but the battery should last longer if you charge it when it reaches 50% as opposed to 0% (that would qualify as "half" a discharge cycle).
When I'm using my device heavily and I have access to an outlet, I leave it plugged in. That saves on discharge cycles. Also, when I am sitting at my desk at work I generally keep it plugged in.
The following link is an excellent source of information regarding batteries:
http://batteryuniversity.com/learn/
right now with my current phone i'll usually just top it off after work from a wall outlet, or top it off in the morning when i wake up and get ready for work. i also have a usb cable at work to top off whenever needed throughout the day. i try to keep the battery over 50% most of the time, just because, but i rarely leave it plugged in throughout the entire night, and this is even with running sleep tracking apps. i imagine battery use/charging will be the same with the nexus 5 -- topping off in the morning while getting ready for work, maybe charge a bit while at work via usb cable, and topping off after work via wall outlet.
i guess i charge my battery in intervals throughout the day, instead of the daily 8 hour overnight charge. however, i usually keep it at least half full
Plug it in at night before I go to sleep.
If i'm using it heavily and it gets below 50%, I'll plug it in.
Some days at the office I'll plug it in about an hour before I leave so it'll be almost 100% after work.
If i'm going somewhere and feel I may run the battery down before I get home, I'll carry my portable charger with me (Anker 5600mAh).

Wouldn't heavy usage while its charging put too much heat on the battery? Which is worse for it then worrying about charge cycles?

It depends whether/how much heat is generated during heavy usage. On my N7 while browsing the net or watching videos the heat is non-existent. Certain games cause more heat than others. If the device starts to become "hot" then yeah, keeping it plugged in will only exacerbate the problem.
Also, having a case on the device can increase heat soak.
It depends on the situation.
You are right though that heat is the enemy when it comes to batteries. About an hour in my back-back on a beach on Oahu killed my GNex battery, and it was in the shade too.
I plug mine into a wall charger or my laptop...
At the end of the day though, if you don't bake or freeze your phone, the battery should last at least a couple of years without losing too much capacity I think.
The battery longevity discussion with mobile devices is similar to the oil change debate in automotive circles. Some people swear by certain brands and oil change intervals, whilst others just buy what is on sale and change the oil when the car tells them too. It probably makes very little difference in the end.

To OP:
Today's lithium ion batteries are way better than what they were 10 years ago. As posted above, go to battery university and learn all about it. My advice? Don't worry about special ways to charge your phone. You'll break, sell, or permanently store this phone long before your battery gives out due to charge cycles.

This!
Once upon a time I used to wait till my phone drained to 0-5% before I charged it. But I quickly realized that doing so turned my battery into trash.
So now with my 2 latest phones I usually charge it when they are at 30-40% or higher if possible and not only do I get excellent battery time but also its lifespan & performance doesn't deteriorate over time.

The only advice you need: DO NOT FULLY DISCHARGE LI-ION BATTERIES. These aren't NiCads, you do not need to power-cycle them periodically.
For best Li-ion life, try and avoid discharging below 20% or above 80%. Manufacturers will often add some 'headroom' to the 100% level (so that a battery that reads 100% is actually only charged to 80%-90% of capacity) in order to maximise longevity. within that range, charging and discharing will have little effect on battery life. charge and discharge rates do have an effect, but again ythe battery controller will limit these to prevent damage to the battery, so this is not something you need to worry about yourself.
Keep the battery topped up and avoid discharging it completely. Anything else is hocus-pocus or incorrect advice for the wrong battery chemistry.
i replace my phone once a year so i dont bother with saving the battery etc.. ive never had any measurable degradation to the battery the way i charge in less than a year. I usually charge it from what ever % its at to full. Most of the day at work it stays on my wireless charger, but it stops charging it after its full.
Thanks everyone for the feedback this far, in just a couple of minutes I already learned a lot.
Please let's continue the talk and vote if you can!
Thanks again.
On the charger before reaching 10%, around 20% or higher if it's possible.

Thanks to this two people.
Before i read this, me always charge the @ 10% or below.
+1 :good:
I just discharge to 20%-40%, then charge it with the included charger overnight...
I've tried using slow chargers but didn't really make the battery any better.
I agree that discharging it fully is bad. Very bad.
I just charge it how it's mean to be charged and I don't have any problems

I've been charging wrong this whole time! Will start charging before I hit 10% from now on. Glad I saw this, just got a new phone and am hoping to keep it for as long as possible...
I charge it every night because I have to use it all day.

I've been using both the incipio offgrid, and tumi powerpack battery mods (both are wireless charging variants) and have noticed just awful battery life. from 100% it charges my phone up maybe 15-20 percent, and thats with the screen off, just streaming music. If I'm using the phone (just surfing the web or instagram) the battery dies in around 30-45 minutes, is this normal? I expected alot more out of these. I can just stare at the notification bar and watch as the battery drops, my software is up to date, and I was just wondering if this is normal? Is everyone else getting this awful performance? I expected way more for like 70-80 bucks each...

This is not normal. While I don't have either of these, based on the reading I've done and reports I've seen from people who do, the Incipio off grid should be able to charge your phone up 50-75% when attached. Not sure if you have some crazy wakelock that's keeping your CPU maxed out all the time or what, but dying in 30-40 minutes makes no sense.

When I got it to die In 30-40 min I was on a phone call and surfing instagram. Took the tumi out yesterday with 80% battery in it and had my phones screen off streaming music over Bluetooth. The phone charged up about 25% before the battery pack died. Any ideas on how I could improve the battery life? My moto mods manager is up to date and I don't get any prompts to update anything whenever I snap on the mods
I was surprised when I found this post, so I checked how many percent of battery do I get with a my incipio battery mod. I plugged the mod, my phone's battery was at 15% and the battery mod was at 100%.
Now the Incipio battery mod is empty and my phone's battery is at 50%. So it charged my phone by 35%.
Pretty disappointing for a 2220 mAh battery that costs almost 100€ ...
To me the best use of the mod is to snap it on when the Moto Z Play is fully charged and to chose the option to keep the phone battery at 80%. With normal use, i've seen the mod keep the phone at 80% for up to a day. To me the mod is not meant to charge the phone but more to keep it from discharging.
To me the idea of the battery mod makes no sense.
There is an Aukey 16000 mAh power pack with QuickCharge 3.0 available which boosts the battery in nearly no time. I paid less than 20 Euro.
Who needs such a battery mod with a Moto Z Play which lasts all day under heavy usage?
Who needs such a battery mod when power packs are big, cheap and fast?
Who even needs the power pack if you have a wall outlet with a QuickCharge 3.0 charger boosting the battery percentage in no time? I needed that power pack when the previous phone (Moto X Play) had some hardware defect making it lose power.
Edit: These questions are meant honestly. Are you living in the desert for several days and can't afford to carry a bag?

The battery mods are not particularly useful for the Z Play because if you charge every night, you have basically unlimited battery life. Battery packs are extremely useful for the regular Z, though, which has extremely poor battery life on its own. They're basically mandatory for the Z.
I'm shocked that battery mods can only charge your internal battery and can't be used directly (discharging the mod battery instead of the internal battery), the same way Thinkpads that have more than one battery can do. That makes the $80 (vs maybe $10 for a 2000 mah ravpower) cost all the more eyebrow-raising.
I'd love to use them as a way of preserving the sealed in internal battery's longevity, making the internal battery the backup battery and wearing out the easily replaceable, easily swappable mods instead.

What do you think how a battery should be treated to prolong its lifetime?
This is a serious question. I'm not sure if charging cycles do matter these days. The point which makes batteries getting weak is the age. An additional battery will not help reduce the age.
Of course you should be careful not to be in extreme cold or heat. If the battery is below 30 percent, you should consider to charge it. You should not charge it again if it's over 80 percent. But trying not to use it seems not to really be helpful for the battery to have a longer life, although battery lifetime usually is given in battery cycles. At least this is my experience. If it does not get hot when used or charged, all batteries nowadays start getting weaker a bit after about 2 years, it gets really recognizable after 4 years, and when they are 6-8 years old, they get so low that they may not fulfill there purpose anymore. Cycles? Never recognized any influence for the lifetime. But one hot day with a usage above average where the battery gets hot may really cause a recognizable decrease in capacity.
If you have some source comparing battery lifetime for different use cases (storage, low usage, middle usage, frequent usage, under different conditions of temperature, fast charge and slow charge) I'd be really interested.

Same sources as you, personal experience and basic knowledge (battery life being measured in cycles). I'm not even completely worried about average aging, but out of a batch of millions of batteries, plenty will start to experience rapid discharge early, even without abnormal heat, not to the point of being completely dead, but certainly no longer tolerable. Today's phone batteries might actually tolerate heat better than in the past, having been built for quick charging, which is the hottest a sd625 seems to get.
I've read manuals and battery university and a few tech blog articles all of which have differing advice, just like you and me, but I have yet to find a source I find credible (based on diverse large scale testing not limited anecdotal evidence or in the case of manuals, insanely outdated nicad-era stuff). And, sincerely no offense intended, I'm unlikely to decide cycles don't matter and weight your anecdotal evidence over mine anymore than you'd weight mine over yours. But if you ever find a good source with those comparisons, I'd be pleased to check it out too.

Because the bat mod is easy to slap on and keep on all the time (when I'm not using a different mod). Then I never have to worry about taking the pack with me or not or carrying the extra cable with me or not.

Because I don't want to have to worry about having the charger with me or finding a spot to charge.
I fully admit that I tend to be more paranoid about running out of power than I need to be, but I like to be secure knowing that I should have more than enough battery life, even if I can't charge overnight. I like to know that I can grab my phone at any point of the day and walk out the door with it without having to worry about taking a charger with me.

I quite like just not having to charge for three days. I have the battery mod which I use on the efficiency mode, and I got over a full day out of it. At the end of day three I had nearly 30% battery left. Probably enough for most of one more day.
The other thing for me is using wireless charging. I like just slapping my phone on a stand overnight when I do charge it. It charges slowly, yes, but it doesn't matter if I am charging overnight. I still have access to the quick charger if I need to get a full battery quick!
I use mine on my motorcycle where I'm riding for 10 hours a day. I'm at about 50% in 4 hours and dead by 7 or 8, so I'm hoping with the additional battery MOD that I can get at least 12 hours charge. I'm really bad about remembering to plug my phone in when I stop for a break!
@tag68 : dude I think you totally missed to read what @fortunz was saying, he was only pointing that he would like the Mods to be used as a primary source battery instead of being a "ultra-portable power bank".
Given that there is also a fraction of the power being lost in the form of heat, during charge/transfer, it is even more silly from Motorola not to have the battery used directly. I can say by the 25-35% charge from the Mods estimated from other users, that the efficiency is somewhere around 50%, HORRIBLE to say the least.
And yeah I was reading through both of your posts and good information was provided, although unnecessary friction used (not naming anyone).
I actually have kind of the same idea from @fortunz to prolong the battery life of my Z-play even with the mod just being a power bank.
Saying that the mods (~2220mah) charge your phone anywhere between 25-35%, I can actually take the top 25-35% out of my internal battery use and move it to the Mod.
So I can charge my phone up to 70% before going to bed, and then when my phone reaches 30% during the use next day, I'll just slap the mod.
I can allow myself a lot of variation to this, I will not be religious about it, the topic is to avoid hitting 100% charge, and instead, moving the wear of that 30% usage to the Mod.
According, to many articles, citing just one below, considering the depth of discharges and voltage levels, you guys might do the equation if you like, but according to the charts and theory:
charging my phone twice a day trying not to exceed 70%, will give me WAY more longevity run than charging up to 100% every day.
First charge will be from around 15% which is my normal deadline to around 70% with a wall charger, before going to bed.
Second charge will be from the mod from around 30% to around 60% (hopefully), which will give me portability while charging.
Total screen on time during the day, should be around 10% less, but well worth and I can definitely take the hit if getting more battery longevity as a trade.

Huh, it even makes sense when explaining to other people...
In re: friction, I took no offense from the exchange. Hopefully I didn't cause any either.
Good luck with your efforts. I have considered using this app to to stop charging early: https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002 Haven't started using it yet.

Sadly that application requires root... and I don't want to unlock the bootloader and then having to worry about SafetyNet...
For me SafetyNet is green using Magisk 12.0 as root solution, but that may change of course. But it would help for the battery.
Short rant about this topic: It is strange that the owner of a device can be forbidden to restrict the charging. You bought it, you should be able to do these things with it. Introducing SafetyNet is a bad idea by Google. Security should be made by algorithms, not by hardware. Using public key anyone may modify anything, and you can still assure the content to be trustworthy. There no need to prove the Android not to be modified, it is just a bad idea, unnecessary restricting the user. Owner.

Well said
Thanks for the tip! I'll have it mind!
At the moment I don't feel like unlocking the bootloader because I'm planning to use the moto Mods and these can't be used with custom ROMs yet, and I have no use for root other than changing the work mode on Greenify but it already works well enough in No-Root mode, so for me there is no true benefit.
A good resource for lithium batteries are rc helicopter forums. Helis use speed controllers of many tens of amps, drain the batteries in minutes versus days to low levels and charge them at high speed. What reduces their life is heat, overcharging the voltage or over discharging the voltage. They do not age if left in a partial charge. You can let them sit for years unused and they will lose very little capacity. If you only run them at 70%cycle, they last about 3000 cycles.
Well, that was weird.
Phone at 9%, mophie mod at 100%. Put it on, barely used the phone (even took a nap). About an hour later, the mophie mod is at 50%, but the phone actually went down to 8%. Took off the mod and the phone went immediately to 4%. Ouch.
Mod normally works fine. It'll keep the phone at 80% for most of the day just fine. Not sure what was going on.
For the last few years I've been reading that it's best to charge your battery at around 30-40% up to 80 or 85%.
Despite this possibly being the best practice, I don't see much point in paying for a $1200+ with a 4100mah battery and only using 40-50% of it's capacity.
So do you charge at around 10% and then go up to a hundred?
Generally I charge when I need to. I like to be topped up to a 100% when I leave the house. Maybe this isn't best practice. I could wait until it get to about 20% but I am wary about using all the battery cycles up.
PLUS I doubt you're going to get 6-7 out SOT if you charge at around 30 or 40%.
So what do you guys do with your s10e, 10s or s10 +?
Charge it whenever. Why the heck limit myself to 60% (say from 20-80% when even my usage pattern won't cause the battery to wear down to 80% capacity over that same time frame by my charging methods?
I also don't tend to keep my phones for more than a year, so wear level doesn't really affect me much
There is no way to "charge it best". Just use it and charge it when needed.
People take out of date "battery knowledge" from the NiCAD battery days and think that modern batteries develop "memories" and things and that hasn't been the case in decades... Just use it and don't worry about it. A battery is only gonna last 2 years at best anyways, so who cares if you shorten that by 2 months?
I normally charge my S10 from 25% to 90%.
The battery of my previous S7 Edge started suffering after almost a year and a half because I used to always keep it charging overnight.
If you don't intend to keep using your phone for more than a year, then don't limit charging your phone. Even in the case it wears off after a year, you can get your battery replaced by Samsung and start fresh again.
I charge mine around 20-30% all the way to 100% . Then unplugged it whenever I need to.
Is there a good "battery charge limit" app that doesn't require root or Magisk? I used Battery Charge Limit (https://play.google.com/store/apps/details?id=com.slash.batterychargelimit&hl=en_US) and it works great, but requires root privilege. It allows you to set upper and lower limits for charging, so you don't overcharge or let your battery drain.
Batteries don't overcharge. They hit 100% and then trickle charge...
Li-Ion batteries are durable and easy to maintain, you can't overcharge them and also the charging cycles doesn't matter - when you use the integrated Charing electronics in your device. You can charge it for a few minutes over the whole day without losing any capacity. Only over the time the capacity will get lower and lower, but this is an issue you can't avoid.
The charging controller in your device cares about voltage and loading current, never put a current on a Li-Ion battery without current limiter and voltage regulator.
But Li-Ion are very sensitive to mechanical damages and production faults.
Thanks for all the advice guys. Nice to see that most of us feel the same way.
Agree with the others. Technically, for optimum life, they say it's best to be between 40%-80%.
But really, just charge it when you need to charge it. Don't worry about numbers or percentages. If you're only going to own the device for a few years, no matter how you charge your device, it's going to have absolutely no affect on the battery over that time. It'll still be holding almost the same amount of charge in a couple of years regardless of which "charging strategy" you use.
TLDR: don't worry about percentage, charge it when you feel like it or when it needs it.
Go here and follow these principles. End off.

I always stay in the range from 40/50% to 75/80% on my Galaxy Note 8 which I had for 18mos.
Accubattery shows it still has 97% capacity.

so you probably charge ur phone 6 times a day? no thanks
@SquireSCA I believe it's a narrow-minded approach to say that the phone battery will "last 2 years at best anyways, so who cares". I'm currently still rocking my Samsung Galaxy S5 which I bought brand new just over 5 years ago now on it's original battery. The battery is by no means like it was when it was new, but it will still last a day of light usage, and still runs perfectly fine with Android 5 installed. This preservation of the battery comes after years of charging it slowly on a charger outputting less than 1 amp and also making sure it rarely goes below 20%, spending most of it's time between 20%-80%.
If you you want to double your battery life you have to keep your li-ion battery between 3.7V and 4.2V. you have to stop the charge when the battery reach 4.2V so it means you have to keep your battery between 15%-85%.
---------- Post added at 09:24 AM ---------- Previous post was at 09:22 AM ----------
Personally I keep my battery between 15-85% which is sufficient to double it's battery life for a 3-year usage without big losses
Idk i heard ppl saying you should let it completely drain and recharge at least once a month. i charge at 15%. Oh well i only keep this phone for a year and then sell it.
It's mostly BS. There are hundreds of charging theories and no battery experts here so pick one and go with it. Pick the wrong one and instead of getting 8 hours on your batter 2 years down the road you'll probably only get 7.5 hours.
