How many times you can charge a Diamond battery?? - Touch Diamond, MDA Compact IV General

I red last week somewhere that a liion battery lifetime isabout 300 times charging, does anybody now or this is true?

You can find there answer to your question..

The life span is dependent upon aging (shelf life). From time of manufacturing, regardless of whether it was charged or the number of charge/discharge cycles, the battery will decline slowly and predictably in capacity. This means an older battery will not last as long as a new battery due solely to its age, unlike other batteries. This drawback is not widely published.

same, my diamond is connected about the same amount of times per day, and then left on charge when im at home to ensure i have adequate battery, eek!

I think the 300 times charging is refer to 300 full complete cycle of charging. It need to be refer to complete a cycle from fully discharge to fully charge. If you charge your battery from 50% to 100%. It is only 1/2 cylce.
Anyone can correct if i'm wrong.

I think a complete discharge counts as 1. If you charge the battery now and then without letting it discharge completely it will last longer. This is quite Li-Ion specific.

In heavy usage a battery lasts for 2 years easy.

Even when you charge it 2 times a day? This should mean about 1400 charging?

Right, firstly, forget anything that has been written above. 300 is crap. (the film '300' isnt tho)
lithium ion batteries generally last longer when kept topped up, rather than cycled.
The batteries in out Diamonds are lith ion, but have been specifically designed for top up charging, therefore last longer.
you can expect your battery to last for 3 years of continuos use, unless there is a fault or it is damaged. It will slowely deteriorate over time.
I have just bought a new battery for my laptop, which is Lithium Ion, as was the original. This is after 10 years!

OK. I know it is out of the topic, but i still want to say: My laptop which is a precision workstation laptop's battery only last 1 year.
So, it is fair that if you discharge and charge frequently, it will deteriorate faster. This is fair enough.

Li-ion battery life - the facts
Skipping back to the facts for a moment.... the HTC Diamond standard battery is a Li ion battery with Co chemistry.
1. Li-ion batteries last between 300-500 deep cycles (from 0% to 100%).
2. Partial recharges are good. A partial recharge from ~25% to ~75% is less damaging than a recharge from 0-100%, and only counts (roughly) as around 1/4 of the impact of a deep cycle. Li ion technology has no charge memory effect, which means that the battery capacity is completely unaffected by partial charging (n.b. this is NOT the case for NiCad or NiMH technology).
3. Li-ion batteries also decay at a constant rate over time, dependent on temperature, and regardless of use. They lose around 20% capacity per year at 25C, but this is increased at higher temperatures. Shelf life is optimised by keeping unused batteries at 6C (fridge temp) and with ~40% charge. But do not freeze them!
4. 100% charge causes accelerated decay rates. So keep your battery below full charge.
5. Deep cycle the battery occasionally (~once per 30 charges), to recalibrate your charge meter. Otherwise the charge level shown will become inaccurate.
6. Key advantage for Co chemistry is high energy density - up to 200mWh/g. Key disadvantage is the charge/discharge limit, which is ~1.2 coulomb.
7. Conclusion is that you can expect your Diamond battery to last for ~3 yrs of hard daily use. If you take care of it, it will last for double that time.

[Q] When should i charge the battery?

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
http://forum.xda-developers.com/showthread.php?t=733705
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

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.
Paulo
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...

[Q] Any disadvantages of frequent charging?

Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?
Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..
True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.
Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.
As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.
Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.
frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....
FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

Maximizing Nexus 4 battery charge cycles. Reducing battery capacity drop.

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.

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.

Concerning the Nexus 5 battery, how do you recharge your device?

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?
I do a backflip spin 360 before charging my phone...

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.

Smart alecks. Granted, I got a chuckle.
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.

When should you charge and unplug your battery.

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.
