Hi,
OneUI 5.0 and previous one also introduced protect battery that doesn't allow u charge phone above 85%. I am using it often because for me it dont affect my phone usage patterns. I can charge phone at least once per 8h and it is almost impossible to discharge phone in time (I have S23+ but I am posting here cuz its more active tag). I am leaving house at 80% and coming back at 50% in overtime scenario.
But also I read it is healthy to full discharge (or till 5-10%) and then full charge phone at least once a month and some sources says even more frequently to do it.
On one side rumours says u should always avoid discharging under 25% and charging over 80%, and other says u should relatively frequently discharge ur phone and then charge it up till full.
I want to know how it works in theory I am not interested in getting answers like "lol man why u even care, phone is for you not otherwise" - because it is often answer in topics like that.
I think that charging to 85% with low speed will be more than enough.
I saw with my gf phone, hauwei p30 pro.
I tried so hard to "teach" her a proper charging routine, but she just doesn't care. The only thing I managed to do is silently enable the "smart charging" to stop charge battery under max capacity.
After 3 years honestly her battery life is still great, as it was mine with the regular Huawei p30 (me, a maniac as you).
Anyway, if you really like the phone, you can afford replace battery after 4 years (should be even cheaper with s23 ultra)

I am using 20W to charge my S23+ so it is not slowest charge but not fastest aswell. Still alot slower than chinese products offering 100W+. I think charging from 20 do 80 in like 35-40 mins is really healthy for battery.
My problem with replacing battery is more that it is hard to find original one and find service that can replace it without losing data and other stuff. At least I had much problems with it with my previous phone but it was realme not samsung so I am aware after 2 years I will have problems with replacing it.
Minimize the current drain. Higher current drain reduces the battery's life span by requiring more full charge cycles for the tasks but also by raising the operating temperature.
Avoid starting a charge cycle below a battery temperature of 72F, 82 is better. Keep charging temps below 102F. 82-99F is ideal.
NEVER attempt to charge a Li that's near freezing temperatures.
Li's prefer frequent midrange power cycling rather than longer usage/charge times. My typical cutoff is 40% or higher and 72% if I'm trying to extend the battery life. Ideally it should be allowed to "settle" after a charge before using.
Never charge with the display on.
When the battery reaches 80% of its new capacity it's considered degraded and should be replaced. Degraded cells are more likely to fail. Any swelling is a failure, replace immediately. A failed Li can damage the display.
I totaly abused my note 10 plus from september 2019 to february 2023, so almost 4 years - charging to 100%, connecting/disconnecting whenever i needed it, playing games while charging everyday, draining it to 0% sometimes, other times it was on 92% or 87% and i was planning a long day, so i charge it to 100%, full abuse. My battery was in perfect condition till the day i bought the s23u. I think that the quality of the battery matters much more than the way you use it, your usage patterns have very little effect on the battery in the period you use your phone. Maybe if we start using our phones for 10-15 years, it will matter, but...
I don't do the stop at 85% on my devices but I do turn off all fast charging and I'm happy with that, but that's just me.
1) Don't put your phone on charge and sleep 10 hours.
2) Keep your charge between sweet spots. %40 - %80 is always ideal.
3) Fast charging does not harm.
4) Don't play games while charging.
5) Don't let your phone get too hot. Hot battery die sooner.
I use default 25w oficial charger from Samsung S21 Ultra, i have like 4 of those and i see no point in having a 45w to shave 10mins of charging time. Fast charging enabled.
I also made a routine, on Saturday and Sunday it disables battery protection so it charges 100% for when i travel and use camera a lot, during work days battery protection(85%) is enabled by default.
I have my S23U 1080p 120hz using light mode all the time and i'm having good results.
in my life I've had a lot of smartphones and what I can say is that I've never performed these types of charges from 25% to 85% and I've never had a problem, however where I had problems was with smartphones that had a processor badly optimizing the heating prevents the battery from working properly and above all the cables and chargers if you use non-official chargers or damage your battery, there is a risk of damage
From what I read it does not matter if you charge to 100 % but you should not continue charging it.
To prevent this I just made a routine that turns on the 85 % mode as soon as it reaches 99 % (I guess I could've chosen 100 % but did not...). Then it stops charging and I wake up with around 99 % charge..
Try to not go below 30% and never ever go to 0 or close to it. Li Ion battery are fragile in deep discharge as same li polymer batteries. So never go in deep discharge, it makes more damage to the battery than charge it to 100%. I have 10y lipos batteries for my RC models that i never go below 30% and they still have 95% of capacity... 10y and running fine in hard condition RC helicopters that pulls all the battery to 30% in 5 minutes. Li ion are the same...
Why not play games while charging? Isn't also supposed top have power passthrough?

Well probably it is because gaming = heat and chargin = heat. Double source of heat may cause battery damage. This is probably the only reason.
Battery University has a really good article on what causes excess battery damage.
Basically, after manufacturing, the battery will get damaged even if it just sits there. But the things to really look out for:
Don't leave the battery discharged
Avoid heat
Don't charge when the battery is cold
Don't charge when the battery is hot
Fast charging creates heat
Don't charge/discharge above a rate of 1C
Don't keep the battery at a high voltage (fully charged)
So keep the battery between ~30-80% at a reasonable temperature
Since my first smartphone (a BlackBerry Curve) I've charged my phone's to 100%, left them on the charger all night, and plugged in in the car. I've never seen a noticeable degradation of battery life. I know it happens, but I think it's been blown out of proportion.
What's the point of a big battery and great battery life if you ly charge it to 85%? I think by the time the battery actually reached the point that it only had the equivalent of 85% health/life you'll be long ready to trade it in.

If you plan to hold it for at least 4 years its worth saving battery. And i believe this is the phone i'm going to hold for a long time. And like i said before, using routine for weekends at 100% battery.
This is me today at work, from 85% to 71% in 10 hours, 35min sot, with 4 calls less then 5min each since i'm at work i can't use my phone all the time. 1080p, 120hz, ligth mode. wifi and bluetooth enabled with watch honor magic 2 connected.
I know it's in Portuguese but you can understand by icons and stuff.

To save battery for max you should always have from 50 to 70% charge from 10C* to 45C* do not use phone lower or higher degrees it may cause bad reaction to battery. Do not use fast charge all this stuff based on a lot of researches you can find it.

Ok, if you're going to keep it that long I can see trying to maintain the battery. I do trade in yearly, but in that year Ive never seen any degradation. And I do all the things you're not supposed to. It stays in my car on the charger in the heat and the cold. I leave it charging all night. I abuse TF out of my battery. The rest of the phone I keep pristine tho, LOL.
I don't worry about battery at all. I love fast charging option and it's always on. I need the phone to charge fast, even though Samsung's 45W is actually really slow today. Why I don't care? Because my 2 years warranty covers the battery issues too (2X per year) so I can ask them to exchange the battery if the condition degrades.

Agree, fast charging is just too convenient. I do limit top charge and discharge % though. On this heavily used N10+ I expect about a 2 year battery lifespan. Battery change outs aren't that hard or expensive. It's going to be on its 3rd battery soon. The first one had a hard life because the phone wasn't properly optimized the first few months; constant high current drains will kill the battery prematurely.

I know this is a long read, please bare with me, as I not only am reviewing the Yoobao battery but also, providing some information on batteries in general and how the G1 battery works (read post 11).
A few days ago I got a Yoobao 2400MAH battery on ebay for $25 shipped. Here's my little review so far after a few days of use.
Background: I'm an avid RC flyer. I own electric powered and gas powered planes and have done a lot of work with Lipo and Li-ion batteries and have applied the same things I've learned from there to any and all batteries.
Few things I've learned is never let a battery drain to it's bare minimum. I've read numerous times that one should let the battery die all the way and charge it all the way and let it die again. For Lipo and Li-On, 80-90% drain is ideal before recharging again. I'll continue with this later. This does not apply to the G1 though, just a general pointer. Read post 11 to see why this does not apply to G1.
Now on to the battery.
The battery comes with the the extended cover. Which has a nice rubbery feel to it.
The battery came with the charge at 70%, which is nominal for shipping and storage. i got it and plugged it in and charged to to max. I then used it through out the day and right off the bat, it was performing wonderfully. By the end of the day, I still had 60% power left, when normally, I would have drained the stock battery by now. I did not charge the battery that night (Monday night) and by morning still have 50% charge. I charged it when it was down to about 15%, a full charge took about 2.2 hours. Which sounds about right, assuming the wall charger was providing 1Amp constant, the 2.2 hours of charge time equates to about 2200Mah of charge.
From a full charge, I've watched a 2 hour long movie, gtalked, SMSed and it has drained about 40% (60% remaining).
It is typically offering twice the length then my stock battery was, Though I've had it 3 days, I will continually update this thread.
i do have the tools and equipment to measure the charge this batter takes in So I will do that tonight and report my findings. I plan to drain the battery to 15% and charge with my digital charger and see how many MAH it takes in. I expect it to take in minimum 2000mah at 85% discharge.
So far, I give it a thumbs up especially at $25.
My brother has the seido 2600. I will test that as well.
Pointers:
Conditioning the Li-on battery by draining it to 0% and recharging and then draining to 0% is rather harmful to the battery. Lipo and Li-on cells do like going below 3.0-3.2V. The Nominal Voltage of the cell is 3.7V, a fully charged cell is at 4.2V-4.25V or so. Dropping it below 3.0V cause more harm to the battery then good. (Again this does not apply to G1)
Try to avoid draining the battery all the way if you are not able to charge it. Most phones have a cut off point, and my guess is for the G1 battery, it's 3.2V, or I hope it is (actually, it's 3.5V as you will read about it in post 11). But you use the phone to where it cuts of, and are not able to charge the batter for a few days, then that could drop the voltage to below 3.0 (over time). I've seen people do this when they use multiple batteries, and end up killing all of them because they let them sit while fully discharged. Big no no with Li-ons.
LI-on doesn't suffer from memory loss , charge them whenever possible. They do how ever become uncalibrated. Meaning if you constantly plug it in at random discharges (which is perfectly fine), the state of charge may differ from the actual charge gauge. Simple problem to resolve, Drain the battery too 3.2V ( I will post if draining the battery on the g1 to 0% is 3.2V or not) and fully recharge.
More numbers on the Yoobao, Seido and stock batter later.
Thanks for the info. I was a little taken aback when I read about this "drain it all the way" advice too. I just got my g1 and I'm still on the stock battery. I'm curious to know what you find.
Thanks for posting.
Very good review man. I hope this one doesn't get merged with that big o battery thread. This one actually has information coming from someone that knows their stuff.

I moved it here, and placed that warning.
Sorry about that, I totally overlooked the accessories section . I was wondering why no one was replying lol.
Anyways, I still can't do the test because I'm waiting for the battery to die! I charged it yesterday morning, Since then I have turned t he brightness at 75%, been using it at the gym, browsing the web, and was on the phone yesterday for atleast 2 hours and was on gtalk last night for a about an hour. Then left the phone on all last night (though in standby).
I do have wi-fi and GPS OFF as I don't use it, it is working 3G.
Currently I'm at 46% so Still waiting for the thing to go down to 15%. Maybe I can finally drain it down today and test it tonight.

That's the first time I'm hearing about someone waiting for their battery to die Good review
very good review .im glad your reviewing the 2400 and hope fully 2600. i am getting ready to buy one or the other ,i know the is a big price diff. between them.cant wait till ya update this thread
Alright so Last night I finally got the battery down to 9%. I've got some interesting findings.
Few more things I'd like to point out before presenting some numbers.
Background on battery ratings: Batteries are rated in mAH aka Milliamp Hour, or how much power/charge a battery will hold. How is this measured? I won't go into details so will just give a run down version of it. Batteries are rated from their lower cutt-off voltage to the maximum voltage. The lower cut-off voltage for Li-ion and Li-po is 3.0-3.2V (3.2V being ideal).
The mAH rating is the amount of charge that it took to take the battery from 3.2V to 4.2V. In the Li-ion case, the lower cutt-off is 3.2V, the Nominal voltage is 3.7V and the maximum voltage is 4.2. Anything under 3.2V is over draining and anything over 4.2 is overcharging.
Why do I bring up the above? to give you an idea of how these batteries get rated.
Often companies will rate their batteries from a lower cut-off point to have HIGHER CAPACITY RATING. For example, if I Charge a li-ion cell from 3.0V to 4.2V, it will take in extra capacity as opposed to if I charge it from 3.2V to 4.2v, It just looks good on paper and spec sheet. This happens often. same with AA rechargeables, the lower cutt-off range is usually 1.0V but often companies will rate from .9V to achieve higher numbers. You will never see this disclosed on the battery, you'll just see the rating. (It will never say Capacity 1800mAH from .9v) etc.
Again, what's the point? There are a couple of points.
1) The G1 NEVER drains the battery down to 3.2V. It's cut-off point is surprisingly 3.5V. I do not know the specifics, perhaps the G1 cannot operate below 3.5V.
This means that even though the phone is dead, the battery still has some juice in it, just not enough to power the G1 or it may be enough to power the G1 but the power management of G1 is not allowing it.
The stock G1 battery which is rated at 1150 mAH, is only being used down to 3.5V, which means you're only using ABOUT 800-900 mAH of it's capacity before phone shuts off.
2) This Yoobao battery is surprisingly, very well rated. At 9 % power, It was still reading 3.6V. REMEMBER: that's 9% till the 3.5V cut off. The battery was most likely rated at 2400mAH from 3.2V! When I hooked it up to my li-ion charger, I was able to push in roughly 2000mAH. so In other words I rate this battery 2000mAH from 3.6V. Yoobao rated it 2400mAH from likely 3.2V. And I would conclude that the rating is accurate and not over inflated.
CONCLUSION: You will never use the full capacity of the battery just because of the way the G1 is designed. It will always cut off at 3.5V. The good thing about this is you will never over drain your battery, so you can run your G1 to the dead point as many times as you want as you will never go below 3.5V. Nice feature but I'd rather have it go down to 3.2 so I can squeeze that extra power out of the battery (Wonder if this could be software modified).
TWO THUMBS UP!!! to YOOBAO 2400mAH battery. Priced at $25.
Some rough numbers:
Stock 1150mAH : 850-950 useable mAH
2400mAH: 2000-2100 useable mAH
2600mAH: ASSUMED 2200-2350 usebale mAH as I have not test my brothers seido yet.
Any questions, I'm happy to answer them.
*I'm in no way shape or form related to the manufacturer of any batteries, I'm just a regular consumer who bought the extended battery and decided to review it since it's rather a new product.

Im considering getting this new batttery is the phone a lot thicker in the hand, could yoy post photos ? cheers
i was thinking of getting this for my girlfriend instead of a mugen power one like i have but i just wanted to know about the battery cover this comes with.
my mugen has these little plastic cone things that go to the camera lens and speaker phone to help keep crap from my pockets from getting all the way inside and it helps with speaker sound, so my question is does this battery back have anything like that or is it just hollow or something?
thanks
Some pictures as requested. I would save the two pictures where I'm holding the phone with both hands and just go back and forth on those two just to get a idea of how thicker it got.

Cheers for the photos thats sealed the deal for me, off to ebay to sort one out
i wouldnt try the batt if it come from china...
coz there are alot of problems with batts from china....
i.e. battery explosion
Thanks for the review - best one I've read on here, sounds like a good battery.

You do realize that almost all the batteries come from China, right? It's possible to get decent products from there - just because it's "Made in China" doesn't mean it's automatically crap. Need to read reviews, use common sense, etc for something purchased from anyplace.
Hate bidding. I wish there was a "Buy-It-Now" on this item. It's gonna be kinda cool leaving my home and not having to worry about my phone dying.
Edit: Got outbid on Ebay last night. Battery went for $33. Glad I lost. Just order the same one on Ebay with a buy it now for $19.50. I wonder how long the shipping is from China?
There seems to be a debate on this topic as to whether you should do a FULL drain on your battery and I wanted to know what people's thoughts were on this in this forum.
I've used my phone twice now to the point where it has auto powered down on it's own. I will then hit the 'Power' button to ensure that battery is truly at 0% (the capacitative buttons blink for a second to confirm that I've hit the power button but there is no more juice left to turn the phone on).
I will plug into the wall charger and allow it to charge for 4 hours (usually around 4 hours, I'll check back to see and hit the power button and the onscreen battery display will show 100% charged).
I will unplug my phone, power on and keep using until the phone fully drains and powers off on it's own again before repeating this cycle.
However, others have stated that this is NOT necessary for Lithium Ion battery and can actually damage the circuitry of the battery? I've always been under the impression that you need to do a complete & full battery drain for lithium ion batteries at least 3 -5 full cycles/times before the battery has been conditioned/optimized for capacity.
Maybe I'm wrong...after all I'm coming from a G1 and this practice helped my atrocious battery life on that dinosaur!
If this is wrong, when should I be plugging my phone back in to charge? When it gives me the first warning to charge in (battery level turns orange - I assume this about 20% battery left) or on the "critical" battery warning when the battery icon in the notification panel turns red (assuming this is about 10% battery left)?
from what I've read in the past, letting your phone drain completely down until it shuts itself off is not good for the battery. I could be wrong but thats what I've read

Yeah, I've heard both sides and I've conditioned my battery for the G1 because it seemed to drain faster if I plugged it into charge when there was 30% or so still left.
Well, I've done two complete cycles so I guess I'll just try recharging when it hits the red mark next time.
When you plug in to charge? Orange, red or whenever to top off?
i plug my phone in when i go to bed. I dont care what the battery is at. I also charge it while i'm at work so when I leave, its around 90-100%. My battery rarely reaches red.

LOL - that would prematurely killed my battery capacity on the G1! I went thru two batteries before I started draining all the way down. Made a difference between 4-6 hours and 6-10 hours.
Seems like this phone doesn't need to do that tho.
But what're you getting on average for battery life and display on time then?

I do the exact same thing. First with my Captivate and now with the SGS2 and the battery life on my captivate held pretty much exactly the same charge for the entire 15 months I used it. The battery on this SGS2 seems to last about 150-175% of the Captivate battery under the same conditions. I just came back from a week on the road where I spent 9-12 hours a day away from a charger and was using my phone constantly all day long and would get back to the hotel room with 30-40% battery left. Considering I was listening to music, playing plants vs zombies and sending and reading push email constantly throughout the day I am very satisfied with the battery life on this phone. I've never done any kind of conditioning or special battery maintenance.

i stopped looking at my battery stats a long time ago. I'll peak in there once in a while but I dont really care what the stats show because I'm always around a charger. As long as I get through 12 hours or so without charging, i'm happy.
Some devices need a full drain cycle to properly calibrate the fuel gauge - ours does NOT.
Lithium ion batteries don't like deep discharging - in fact discharging them too much will permanently damage them (fortunately, all batteries sold to end users have built-in protection chips to prevent overdischarge - but do you REALLY want to rely on that chip?)
Similarly, they don't like charge being forced into them - so don't "bump charge". (Bump charging is removing and immediately reinserting the charger when the phone says charging is complete.)
For long-term storage, store them at around 50% capacity if not being used. LiIons that are stored at 100% charge lose capacity MUCH faster than ones stored at 50%.
A Li-Ion that has been sitting for a long time (months...) will develop a passivation layer that can be detrimental to performance - a few charge/discharge cycles will fix this. You don't need to do a full discharge/recharge - probably even from 90 to 70 and back up a few times should be fine.

what about short charging during the course of the day? For instance, while I'm at work, I like to plug it in for a bit and then use it off the charger. Then before I leave, I charge it again for a bit. Do you think thats okay to charge the phone for short ~1 hour bursts?
No, the battery itself doesn't do well with deep discharges, but every device with one has circuitry to manage this and keep it from happening. The phone will shut off before the battery reaches a critically low discharge state. Just as it will cease charging before it blows up. Just because the phone shuts off does not mean that the battery is too low.
Assuming the phone has the proper cutoffs, it's not really any different to do two discharges to 50% or one to 100%. There have been studies that say leaving it on a charger is bad, doing two 50% cycles is worse than one 100%, etc. I've always just trusted that the phone manufacturers design the battery monitor and control circuits correctly and not worry much about it. And I've never had to replace a battery yet and always get acceptable life.
It's lithium ion, not nickel cadmium.
Full drains are bad for lithium ion.

lithium ion batteries dont like being under 30%. and they also dont do well if they are kept at 80 percent or above all the time. for longest battery life don't just let it sit on the charger all day after it fully charges.
I agree with Mikey here.
Also, batteries take charging current better (less wear) at lower states of charge. That's why I put a variable-current charging algorithm into my Infuse kernels (charginghacks branch on github)
800 mA at low voltages (200 above stock), dropping to 550 near the end (50 below stock).
Unfortunately, charginghacks is likely not going to be possible with our hardware. One of the differences between the I9100 and I777 is a different battery charger circuit - ours is far less flexible.

This phone actually charges with the screen on though, so it's not like the Infuse where the battery would drain with the screen on and the phone charging.

Infuse would charge with the screen on - but not if the screen was on AND the CPU was cranking.
(worst-case was navigation at full brightness - and I've seen reports that the I9100 also has the same problem.)

When web browsing, playing a game, or other general use late at night I'd plug the Infuse into the charger. It would still drain. Doing the same on the SGS II and it at the very least maintains it's battery level, so it's a drastic improvement over the Infuse.
My old phone's (Xperia S) battery drains very fast (can't last for a day) after 2 years of use. When it was new it lasted about one and a half day. I charged it every day for 2 years and the battery became weaker. I don't want this to happen with my Z2. I use dock for charging my Z2. USB cable or dock is better for the battery? And when should I charge it? wait while the battery drains full or charge it every day and don't let it drain, just about half, or don't charge it full and get it drained every day. And how long should I charge it? just that time while it charge full or leave it charging for longer (a whole night, about 10h)
someone please
I dont think it has anything to do with the way you are using to charge your phone... It's just natural for the battery to need to be replaced after a couple of years as far as i know
As far as I'm aware, after about 500 charge cycles the battery stops charging to full capacity (although it says it is). So the battery quality degrades over time regardless.
the battery of the Z2 is hardly affected by how you charge or how many times its charged
itll start degrading over time
it should be a Li-ion battery (referencing the packaging instructions for Z2)

just charge normaly,
somehow i get the best life out of charging randomly, e.g. never 0>100% or simular but instead 20 to 60% increments gives me the best total life
in terms of wear, cant do anything with a Li-ion battery as far as i know
ok, better charge it when it gets as low as 30% and better not fully charge it, but 85-90% will be great for long term life. and never let it connected if it happened to reach 100%, also better keep it somewhere cold and definitely not under sunlight
It is said to live longer if you charge it from 50 to 90%.
That said, if you charge it from 0 to 100% every 2 days, or charge it from 50 to 90% ever day.... well... the end result is the same... it doesn't matter at all.
The battery already has safety over/undervoltage protection, therfore charching it as you like doesn't change much at all. You will see that a phone left at 100% in the charger will drop to 97-95% before it starts charging again.
i think the battery in the Z2 was said to handle about 600 cycles with less than 10% Battery degration.
if you charge it every 2 days thats about 3.5 years.
There is a lot of false information floating in this thread.(and lol Z2 deals with all, 10/10 loyalty) I was actually replying to this but I wanted a bigger audience to take better care of their battery, so check my thread out : http://forum.xda-developers.com/showpost.php?p=60299964&postcount=1
Hey, just wanted to let you guys(and gals) know that this app works perfectly on our axons: Battery Charge Limit.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
It does exactly as the name suggests, stops the battery from charging beyond a certain percentage, thus for example if you set a limit of 80%, your battery will preserve its health for around 1500 cycles instead of 500 cycles of charging to 100% before degrading by ~20% of its total capacity.
Enjoy the app guys, tested on B19, stock kernel, rooted.
So the way to have 1500 cycles is to only use 70% of battery at best. Because going under 10% is not exactly good for the battery either. I don't want to have an even worse battery life, so I think I'll pass, thanks though!

Don't go under 90ish as you will stop charging whilst quick charging and will damage the battery even more than if you didn't use the mod so just be carefull

Dont let them fool you, you dont need this app. The charging controller of your phone actually already has its safety margin built in. Same on the low end. This means you can not charge your phone to its physical maximum anyway, it will show 100% whipe the physical charge in fact is ~95% and will shutdown showing 0% while physically there is still about 10% of power left. So your battery is safe from this kind of damage anyway.
If you want to extend your batterys lifetime for real, try to charge it as often as you can, keep the charge as high as possible. Flat charging is the magic word. This is what your charging controller does when your phone is connected to ps for longer when it shows 100%, it in fact lets it deplate 2% without showing and then charges it back, thats called trickle charging and is the best treatment practice for our bateries.

Samdung pretty much confirmed they do this (or better) in the S8 and later (and possibly the S7). But has any other company confirmed they have battery longevity tactics built in?
Personally I use AccuBattery since I've had it for a long time as a charge alarm/monitoring tool. I use a 1 amp charger instead of the 3 amp charger that comes with it and charge my phone at low amps and voltage which prevents the battery from heating up. So low charge, low heat. I don't want a degraded battery in a year because I don't know when I'm replacing this thing.

AccuBattery is no good for giving an accurate estimate of the actual capacity when you're charging at low %s. For first 50% it'll calculate something like 3500mAH+, for the last 50% it'll estimate 2000 or lower. If I had to give you a rough estimate of what I actually think it's at, it's roughly 2900-3000mAH. When I first got it, I estimate it was around 3100-3200 a year ago. I HATE that phones no longer have replaceable batteries. That's half the reason I wanted an LG V20, I could just murder the battery and just pop in a new one every year. Sadly the V30 is sealed, following the BS trend of planned obsolescence. Thanks Apple.
Oh and I almost forgot, I typically charge my phone from 20% to 50% after it drops 30%. Then sometimes once more if I use it some more. On average I charge about 50% worth a day without going over 50%. Even with such light battery usage, keeping the battery 30C or lower 99% of time, and keeping the voltage below 4.1 again 99%, it's still degraded at least roughly 200mAH in a year. Rarely when I know I'll need longer battery life I charge it to 80%. It's a cheap quality battery. ZTE cut corners. This was my first, and unless I have no other reasonable options, it'll likely be my last ZTE phone.

my old sony phone form 2011 still works nicely, as it had Quality battery (over 2000 cycles already) yeah does not last long 2/3 but still. useable.
And i agree, replaceable batteries is must have function, My old S3 and S4 worked for "ever" because of that, every year new battery and another year of usage! (s3 still going strong since 2012 !!! )

Essentially, yes, that's what I keep hearing whenever I dig for information. If any of the stats of AccuBattery are accurate at all then it also supports that going over 80% causes multiple times the degradation that charging up to just 80% would. These days I try not to go over 70% based on app estimates of degradation. These days I need more than the 50% I was previously charging to.
I keep reading that you should try and just charge your phone to 80% to help keep the battery healthy, as going to 100% can shotren the life span of the battery.
How ciritcal is this?
I know letting your phone run down to 0% is bad as it takes a fully clylce then to get back too 100% and this is not good for the battery long ter, but i must confess i usually let my battery get to around 50/60% ish then charge back up to 100%
I've always charged my phones fully and never noticed any issues. Maybe if you plan on keeping a device for 10 years, but for the usual lifetime of a phone it's just fine. My OP7 is 2 and a half years old now and still has 86% battery health. I've seen others in Telegram groups say that they never charge to 100% and when they post their battery health it's not much different from mine, sometimes even less.
I think modern batteries are fine being fully charged ... otherwise the OEMs or battery manufacturers would limit them to 80 or 90% by default.

I like the adaptive charging, set up your bedtime and alarm for getting up (or turning over) After bedtime, phone gets trickle charged to achieve 100% at morning alarm. No excess heat etc. Phone then lasts me all day till bedtime when put on airplane mode, switch off Wi-Fi, & sleep. Works for me.
I'm showing 106%
I always charge to full, using adapting charging over night. Charging slowly and keeping temperature down is more important than keeping it to 80% from my understanding.
I just lay my phone on a slow charge Qi pad every night and when I get up it is at 100%. Nexus 6, Pixel 3, now Pixel 6. Perhaps my battery life went down a bit on my Pixel 3 after 3 years, but not enough to notice. I think 100% charge (at least slow charging) is safe for 3 to 5 years of battery life.
Li's like frequent midrange power cycling; it can extend the lifespan hundreds even thousands more full charge cycles.
Voltage and temperature are the Li's biggest stress factors. Low or high temperature charging can cause Li plating.
The higher the cell voltage, the faster it degrades.
The same is true with temperature.
Personally I just replace them every year or so as a failed Li can severely damage a phone. They tend to swell during a failure which can easily damage the display.
My Samsung S10+ is 27 months old now. I'm charging it to 80% mainly daily. Had maybe max 20 full charges and only once or twice to zero. I'm at 86% battery health (according to 146 sessions). Was 92% six months after buying brand new.
I think it helps. Also since the battery is OK (4100mah), dont need that extra 20%.
EDIT: 15W Samsung "fast" charging. As fast as that is ...

A Li is considered degraded when it reaches 80% of it's initial capacity. This signals the end of its useful service life.
Degraded Li's are more likely to fail.
Trust me it's better to replace it before it fails...
I think Better Battery Stats made that reco back in the day.
Charge to 80% and plug in at 10%.
Not so sure that really matters anymore though.
Both my 2 XL and Pixel 5 were plugged in before bed, unplugged when I got up, plugged back in when I hit 10-15% or when I went to bed.
If you plan on keeping your device for a long time (like 3-4 years) doing the unplug at 80% and plug in at 10% might make a diff.

10% is too low. It causes a lot of stress on the battery as it drops below 20% to charge from that starting point or lower.
Worse there's little usable energy after 20% because of the lower voltage. The phone uses the same wattage which is determined by V×A=W, so as the voltage drops it needs more milliamperes to make the same wattage. The discharge rate increases as the cell voltage drops.
A better low cut off is 30-40% or even higher and a high cutoff of 80% although 62% is optimum.
The Li likes frequent midrange power cycling. Charging beyond those parameters is for your convenience at the cost of battery lifespan.
Batteries are cheap and most are easy to replace... so I don't sweat it.
I expect a service life of 1-2 years on a heavily used N10+ battery.
However charging in the 40-72% range yields the most rapid fast charge in the shortest time so it makes sense to use this whenever convenient.
Well, I know things have been updated within Googles code itself.
"Adaptive Charging" / "Adatptive Connectivity" additions.
This was a real big problem for me with my HTC 10, (2016)
Battery degradation threads starting popping up.
I installed Accubattery after 1.5/2 years of owning the device and the battery was degraded to about 77% capacity at that time, IIRC. I was charging to 100% at that time, also.
So, I began charging stricly to 80%.
Compared to my HTC One M8 that to this day still has 90% capacity, and I used that device from the day Verizon released (3/2014) it until the day Verizon released the HTC 10 (5/2016).
I somehow managed to use the HTC 10 up until I bought the Pixel 5 on release day (10/2020).
I was charging the HTC 10 like 3 times a day just get through, and even went back to the HTC One M8 at one point because I had enough, but was waiting for the P5 to drop.
So to answer the question, I do believe it helps.
I do think that Adaptive charging/connectivity help, as well.
I take the view that if I don't need all the capacity on a particular day I charge no higher than 70%, which lands me around 30% end of day. Otherwise I'll guestimate what I need. Off to take some photo's tonight, so will probably charge it to 90% or so.
If you like fiddling around you can use something like Tasker to switch a smart plug that your charger's plugged into on and off at what you consider appropriate battery levels. Makes it all painless once set up. Or you can buy some extra hardware too. I use this in my car to limit the phone's max charge and temperature as, for me, I think most and fastest damage is done in a hot car float charging the phone at 100%.... https://chargie.org/ Not cheap but ok in my mind to hopefully extend the service life of the phone's battery. Less than the cost and hassle of replacing a battery anyway! (I'm not associated with Chargie other than as a customer)
OK, admittedly off-topic, but, this kind of sounds like a variation of the guidance I use for charging my electric car. Don't charge it unless it drops below 80% (so don't keep topping it up), but don't let it go below 20% regularly either. I mostly plug it in at around 60% and let it fully charge. Given the cost of a replacement battery would be more than the total value of the car, I hope this gives me 10 year of life.

EV metering is set up differently. What shows as 100% is likely a conservative 80% charge. Research for that variant.
A 35-40% low cut off is probably better as going lower generates more heat causing needless stress... unless you need that capacity.
Just downloaded the accubattery app and then fully charged but it’s estimating 6,401mah. Must be wrong and needs to calibrate over a few days.
I’ve never had any problems charging to 100% before so I’m not stopping now. I’ll be deleting this app if it keeps warning me like it has done.

Just downloaded the accubattery app and then fully charged but it’s estimating 6,401mah. Must be wrong and needs to calibrate over a few days.

I used to cycle from full to empty on my Pixel 2 before recharging, at about 3 years the battery couldnt last until lunch anymore.

Phone always hot and needed to stay on a charger 24/7, would turn off if I opened the camera without usb power connected.
