I think it's more likely just the GSAM bugging, but if you turn Bluetooth on and off again, and it's still high, then it might be that's the problem.

My uneducated guess is that smart switch is fine for some and not for others, I initially used it on this, then did a fresh reset (I find it quite cathartic to start from scratch!) And it definitely felt like it was lasting longer.

I think the issue you will have is it won't show anything beyond the kernel, but worth a try. There were a few other apps like betterbatterystats which could help dig deeper but don't know if they even work anymore.

The one thing I can see is your mobile signal looks pretty bad which would cause drain seeing as you don't have WiFi calling on - Might be worth giving that a go

But yea, try it again, then in the morning get

a) some more screenshots as well as from the Samsung default battery bit in settings

B) before taking GSAM ones, turn your Bluetooth on and off

C) have a look at your data usage, see if anything has been using your WiFi/mobile data in the background
[Samsung Galaxy S23 Ultra] tripjnj:
GSAM started bugging out last night, repeatedly force closing, so I just deleted it. Phone lost 16% in the overnight, but I think I found the culprit. The standard battery tool only showed one app running in the middle of the night and that it only used .1% of the battery. This is a digital car key and digging deeper it shows it in the background pretty much all the time, which makes sense. Looks like I'll need to either disable the key or turn off BT at night to save the juice. Hopefully that does the trick. Thanks for the tips, much appreciated!
[Samsung Galaxy S23 Ultra] mtm1401:
Nice, I have a routine that turns everything off at night including Bluetooth between certain times which might be most hassle free way.

Assuming if you deep sleep the app it'll stop working with the car?

I noticed that charging the battery to 100% is more convenient for me rather than using the 85% option, since I can do 2 full days with one single charge and keeping the battery above 20%.

Therefore, I have created a routine to charge the battery in this way: it first charges to 85% and after 5h, it charges to 100%, this basically replicates "Optimized Charging" from OnePlus, and according to OnePlus, it improves long-term battery health (the point is to lower the amount of time it stays on 100%).

But I do not know if this true and will improve long-term battery health, any thoughts?
[Samsung Galaxy S23 Ultra] EtherealRemnant:
It won't help battery health as much as limiting to 85% charge would but it's better than keeping it pegged to 100% all night.
[Samsung Galaxy S23 Ultra] ssj100:
Can someone actually quantify what the actual absolute degradation difference is by eg. always charging to 100% overnight etc, compared with all these so called battery saving approaches like limiting to 85%?

If it was only a 1-2% difference per year in degradation, then I don't see the point of the potential inconvenience of limiting charge etc, unless you plan to do something like sell the phone in 3-4 years to someone who will specifically reduce the selling price due to more battery degradation?

As I've said before, penalising yourself from Day 1 of owning a flagship device by an absolute difference of 15% every day (you never know when you may need it in any given day with unexpected events etc) seems like more of an issue to me than a few % difference in battery health 4-years later.

BU-808: How to Prolong Lithium-based Batteries

BU meta description needed...

batteryuniversity.com

It's an article worth reading.

There is one thing this device has going for it in spades though... The highest battery temp I've ever registered is 38C and I average 27C. There is much less battery degradation in the lower temperatures.
[Samsung Galaxy S23 Ultra] ssj100:
This is the thing though, the article is reporting some quite impractical conditions - for example no one keeps their phone at 100% charge all the time for 1-year straight. The degradation reported by the article from doing that is actually not that horrible over 1-year at 25 degrees. The absolute difference in degradation compared to keeping it at lower charge (40%) is 16%. For most people's practical purposes, I suspect the absolute difference will be more like <5% per year.

It seems to me that keeping the phone cool is more important though - so maybe store it in the fridge overnight haha.
[Samsung Galaxy S23 Ultra] EtherealRemnant:
I can tell you that charging to 100%, I lost 6% of my 12 Pro Max's battery in 12 months and by 18 I was down another 6%. That's the first phone I had that showed me my battery health. I don't usually keep my phones more than a year so I'm not terribly worried about it but despite not being worried, I use the 85% setting anyway, because the battery is so good on this thing I know it won't die in the middle of the day.
[Samsung Galaxy S23 Ultra] ssj100:
Yes, and what do you lose by charging to 85%? For example, if you lose 4% (instead of 6% you quoted), then that absolute difference is very small and not practically worth limiting charging to 85% in my opinion.
[Samsung Galaxy S23 Ultra] EtherealRemnant:
That last 15% takes much longer to charge anyway. I'm not losing anything though because I have all the bells and whistles turned on and still can get more than 24 hours out of 85% usually.
[Samsung Galaxy S23 Ultra] ssj100:
And that's completely fair.

Ultimately however it wouldn't surprise me if it's mostly psychological in practical terms. For example, charging to only 75% is likely to be better "battery health-wise" than even 85%. But the absolute difference in degradation rate may only be 1% per year. But another person may say they only ever use 50% of battery per day, so 75% is more than enough etc.
[Samsung Galaxy S23 Ultra] cmfCyangenModteam:
Just resetted mah phone. Battery works pretty well, Did the settings stuff on MIUI,
[Samsung Galaxy S23 Ultra] wolfu11:
I agree I'm getting over 2 days of battery on the March update so going to 100 every other day is a no brainier.
[Samsung Galaxy S23 Ultra] aureum:
Well I can tell you from my own experience.

1. I'm charging my company iphone always 100 by night. After 12 months ios shows already lost of 15% in capacity and I'm getting shorts sot already.

2. In my company (that I work for 16y) we use lenovo ThinkPad laptops. On begining like all ppl we use them 100 to 20% mostly. IT need to change batteries every year. After New policy and lenovo vantage options we now use charge to 80% and not charge if battery is higher than 30%. Now IT need to change our batteries every 3 or more years and on my p53 after 3 y I have still same SOT I was have on begining. And company save aaaaa lot money for batteries as ws we have tons of laptops.

3. I have a RC hobby. I fly with 3D helicopters, boats and planes. I use lithium polymer batteries, as for maintanance they are same as li ion. I'm in my hobby for 16y now. Some of my batteries that are F expensive have now 8 y and only 5% loose in capacity. The only rule is do not discharge below 20% and do not left it full for longer than needed (we charge them full just before flight and flight takes 5 minutes) . I use digital chargers that gives info how many mah I can put back to them so in example 2200mah bat after flight have like 400 mah left and I still put 1500 mah I. 8 y old bat.

So yes. The last 15% is wearing battery more than charge often to 85%. As battery reach full capacity the higher is voltage and resistant during charging. Resistance is a key as it makes permanent wear on electrodes. The lower resistance the longer battery life. It is just chemistry.

With my old s10+ that I never discharge below 30% and mostly charge to 85% after 4y I only loose 1h of sot...
[Samsung Galaxy S23 Ultra] Klaudas:
For me I've used s21+ since launch charging it everyday from 10% to 100% overnight. Until I bought s23u on launch and l there was 0 difference. I bought s21+ and getting 5-6h SOT and on the last day before I've sent it I was getting 5-6h SOT.

Same with my acer predator helios 300 laptop. On launch I was getting 3hours of usage. On third year before I sold it I was getting 2:30hours~.

Two years ago I received company lenovo thinkbook. Charging whenever I want, discharging a lot. After 2 years no difference. It lasts about the same.
[Samsung Galaxy S23 Ultra] aureum:
Well this is simple not true at all. Best tech in batts we have now gives 500 cycles when battery loose 20% of its capacity.

My 1y iPhone already have 86% with bad charge hab its as it is company phone.

It simple to calculate as phones easy knows how many mah battery can take, same as digita chargers.

You can try to bend reality but science and battery chemistry do not work this way. Sorry.
[Samsung Galaxy S23 Ultra] Klaudas:
Your problem. Mine lasts amazing even after few years. I live where most of the time temperature outside is colder. 10-25 celsius in the spring, summer and autumn is below 0 celsius in winter. Maybe that helps me.
[Samsung Galaxy S23 Ultra] cmfCyangenModteam:
Mines lasts so good because i did the heavy settings change, limited all pop-ups from system/some sorta of other apps, and limited background battery usage, and alot of more. Trough system would be working badly. ( My phone already have 3 years.
[Samsung Galaxy S23 Ultra] Klaudas:
First your iphone shows incorrect maximum capacity. Google it

"iPhone’s battery health information is not accurate, testing finds"​

Second point heat makes a huge difference.

Third point is that exactly 500 cycles is not true. It's approximately 500. That cycles count depends on various factors. So first learn some science and then mention it.
[Samsung Galaxy S23 Ultra] Thanos88:
Interesting guide 🙏 looks like it says to disable adaptive battery, have you also disabled adaptive battery?

Any idea what android system intelligence is btw?
[Samsung Galaxy S23 Ultra] Fl1nt91:
Yes i disabled because I want to have control on it

I don't know what is this, now I'll try do disable (is possible easily)
[Samsung Galaxy S23 Ultra] Klaudas:
I have enabled that feature(adaptive battery) but most things from that page are set up accordingly. Constantly 6-7 SOT from 85% to 10-20%.

About "android system intelligence" you can read there: https://support.google.com/pixelphone/answer/12112173?hl=en
[Samsung Galaxy S23 Ultra] Thanos88:
How much battery do you lose overnight?
[Samsung Galaxy S23 Ultra] Klaudas:
About 4-5% in 9hours~
[Samsung Galaxy S23 Ultra] Fl1nt91:
Btw, what is the best software to have a detailed report of battery consumption?

The stock one seem quite shallow
[Samsung Galaxy S23 Ultra] Thanos88:
I use gsam battery monitor with ADB commands , works very well
[Samsung Galaxy S23 Ultra] Thanos88:
I lose approx 2% , another user FI1nt91 loses 0%
[Samsung Galaxy S23 Ultra] amirage:
That's respectable. 0% is God mode. Unless the phone is in airplane mode at night and sync/location is disabled, I don't think 0% is achievable
[Samsung Galaxy S23 Ultra] ZayaanAhyaan:
Coming from S22 U snapdragon, the battery is much much better!! My screen on time on that was 4 odd hours....this one is 6.5 to 7. Last time I enjoyed such amazing battery was on P30 pro, Huawei.
[Samsung Galaxy S23 Ultra] Thanos88:
That's the thing, I have mine in airplane mode at night with every setting off, only the power is on I lose 2%-3%
[Samsung Galaxy S23 Ultra] amirage:
even sync is off? do you have the galaxy wearables app? this app constantly polls for the location even if it's not in the background!
[Samsung Galaxy S23 Ultra] carlosLondon:
Batter is amazing on this. Coming from the S9+, which I had to charge twice a day, it feels amazing. Usually loses around 3% overnight (last night it went from 29% to 26%, and that was with the WIFI on). Battery lasting around 2 days (not super heavy user, just social media, some games, playing with camera/gallery, etc)
[Samsung Galaxy S23 Ultra] Thanos88:
Nope, debloated the wearable app. All sync stuff is off too
[Samsung Galaxy S23 Ultra] amirage:
Do have Gsam? That should give you a good picture why your battery is draining overnight.
[Samsung Galaxy S23 Ultra] Thanos88:
Nope, debloated the wearable app. All sync

I used Gsam, it shows only 2 minutes of wakelock on 10 hours standby, but this shouldn't cause 2% battery drain, infact it shouldn't even cause 1 %. My rog phone 6 has 4.5 mins of wakelocks over 10 hours standby, but doesn't even lose 1%
[Samsung Galaxy S23 Ultra] amirage:
Really don't know bro..it's best to check with @Fl1nt91 for their gsam screenshot. But I don't think that's going to help much, since the apps, network connectivity etc etc would be different. End of the day, do you really want to split hairs over this 2% drain?
[Samsung Galaxy S23 Ultra] Thanos88:
I guess you're right, it's not major
[Samsung Galaxy S23 Ultra] Fl1nt91:
Anyway, next night I'll track better.
[Samsung Galaxy S23 Ultra] lawtq:
Gsam app is crashing for me. Anyone else having this problem? Want to use the damn thing
[Samsung Galaxy S23 Ultra] aureum:
Iphone is just example. It already lost 1h of sot. Heat is same danger for the capacity as high voltage charge and deep discharge. And that is the point with 500 cycles. From 0 to 100 is one cycle, from 30 to 85 is 0.3 cycle and that is whole point of 80% charge to go from 500 cycles to 900 or more or less.
[Samsung Galaxy S23 Ultra] Xoltro:
What is ur average idle battery drain? Cuz I am having like 1-1,5%/h with only wifi on with BT,NFC, Location, LTE off. I dont know if it shouldnt be lower, I am reading that ppl are saying they get 3-4% drain over night (dunno if they turn off Wifi or not), but in night with only wifi on I get like 8% drain.
[Samsung Galaxy S23 Ultra] EtherealRemnant:
This phone is perplexing with the standby drain. One day I'll be getting .8% and the next day 1.5-2%. Same location, same SIM cards, similar activity.
[Samsung Galaxy S23 Ultra] ssj100:
Well there's no doubt that

I completely agree that there are certainly many ways to "save" battery health, and how you describe the above (in quite a wide variety of scenarios and not even quoting Samsung devices in a comparative way) is probably not the most optimal way to do it either - that is, you could probably save even more, but inconvenience/impracticality would start becoming an issue. However, the question is whether it's worth changing approaches at all specifically for Samsung devices.

I know for Electric Cars, some batteries are much better at reducing degradation than others. Generally, there have been significant improvements all around as battery tech improves. The Blade battery for example is so good at reducing degradation that the manufacturer/sales companies don't bother suggesting/recommending their customers charge to 85-90% only like many other brands do.

I can't speak for the iPhone or for laptops/tablets (also wouldn't surprise me if you're using old models which have older anti-degradation battery tech etc), but I can share my real-world experience with having owned 3 previous Samsung phones (prior to S23 Ultra). With the S7 (owned for 2-years) and S9+ (owned for 3-years), I observed what I'd subjectively say as mild degradation by charging to 100% overnight (and thus leaving it "on charge" at 100% for at least 4-6 hours a day). I use the term "mild degradation" as it did not impact my everyday use of the phone at all in terms of battery life. This is what is actually important, rather than measuring some number with some app which may or may not be accurate.

With the S21 Ultra (owned for 2-years), I actually stopped leaving the phone charging overnight, but always topped up to 100% in the evenings (before bedtime) and then disconnected the charger once it hit 100%. That would be the only period of time I'd charge the phone on the vast majority of days. When the phone was brand new, the estimated battery life reported by Device Care ("A full charge will last about") was 2 days and 2 hours. 2-years later, it remains the same. However, more importantly (as referenced above), I also noticed no change in everyday use of the phone in terms of battery life.

Anyway, it's possible that Samsung battery tech is better than (older) iPhone models and other laptops. Who knows really. But anyway, I still don't see any compelling reason to only charge to 85% for my specific use case, but it's interesting to read about other people's experiences.
[Samsung Galaxy S23 Ultra] robbbzilla:
I simply unchecked all fast charging.

I charge the phone overnight and I don't care how fast it charges but I figure the slower it charges the better for the battery. I use the phone heavy throughout the day and lowest percentage on battery at the end of the day was 40%.

I figure if I ever need to fast charge I can just change the settings.

I also try not to charge more than once a day.

Hopefully this should help keep the battery health in a good condition for longest.
[Samsung Galaxy S23 Ultra] matushsvk:
Could you show me how exactly did you setup this routine? I would like to set it up similar to yours, go to sleep, put phone on my wireless charger, charge it at around 75% first and then fully charge it to 100% I hour max before I wake up.
[Samsung Galaxy S23 Ultra] matty100147:
For me I find using the phone with mobile data delivers better battery life than WiFi, I charge my phone to 100% for bedtime and 7 hours later I have lost 3-5% on WiFi but 1-2% on mobile data, using gsam battery monitor I see on WiFi the NLP collector wakelock and another NLP wakelock has my phone awake over 10mins but on mobile data these wakelocks are no more than 10 seconds, so must be bug in the WiFi that keeps my phone awake, hopefully a software update will fix this
[Samsung Galaxy S23 Ultra] EtherealRemnant:
Yeah it does seem like mobile data has better standby drain than wifi. I noticed that myself. It's not a big deal to me though, phone gets me through a full day with ease. I would rather not have to upgrade my mobile data plan lol.
[Samsung Galaxy S23 Ultra] ssj100:
On WiFi (and I presume mobile data too), I've noticed it takes quite some time to drop from 100% to 99% - even with AOD "show always", it will take around 2 hours! I recall this is like Apple, as in it sorta "fakes" at 100% charge for longer than it actually is?

Does anyone else notice this too?
[Samsung Galaxy S23 Ultra] matty100147:
Yes I notice this too, I remember my s22 and s21 would drop to 99% after a minute or two even without using it but my s23 stays at 100 for a couple of hours, the worse phone I had with this tho was a Huawei mate 10 pro a few years back, it stayed at 100 for maybe 6 hours after with light use then when the battery fell below 80% it sank super fast
[Samsung Galaxy S23 Ultra] Xoltro:
Yea it is strange a little I have very weak mobile data signal and still standby battery drain is pretty close to wifi battery drain. In previous phones (s22u, IP13) I had twice more idle battery drain on mobile data than wifi. but probably they will fix it somehow in future updates.
[Samsung Galaxy S23 Ultra] ssj100:
Thanks for confirming - yes my S21 Ultra would drop from 100% to 99% within 10-15 minutes or so with AOD "show always", so this is quite a difference with the S23 Ultra taking around 2 hours!
[Samsung Galaxy S23 Ultra] volcolm:
Curious on faking %...

Do your phones drop charge like a bag of bricks after ~30%? I noticed that both my Note 10+ and S22U (when I had one for a short time) would do their battery like this.

Then 5% happens and the phone just shuts off.

Adopted a S22U early so I know it had some charge shenanigans early on, but curious if 23U do the same?
[Samsung Galaxy S23 Ultra] ssj100:
I've only ever gone down below 50-60% once or twice so far on the S23 Ultra (was doing it on purpose to get down to 0% in order to "calibrate") - I noticed a more dramatic drop once it got <5-10%. Definitely at 4-5%, using moderate-high CPU consumption apps seemed to drop it very quickly.
[Samsung Galaxy S23 Ultra] EtherealRemnant:
The phone stays at 100% for awhile because it's not fully charged when the phone reads 100%. Get an app that can read the wattage going into the phone. It's still pushing 5-7W at that point, quite far from the .2W it drops to at the end of charging.
[Samsung Galaxy S23 Ultra] oryanh:
I find it ironic that if the overall goal is to have the battery last longer for a better user experience; How is deliberately reducing the charge to 85% to prevent the permanent loss of battery capacity create an overall better user experience, when you are penalizing yourself every charge. LOL! That's like running slower in a race to prevent injury but losing deliberately.
[Samsung Galaxy S23 Ultra] oVeRdOsE.:
yeah but this is chemical science, and it applies on all li-ion batteries since it exist.

Not because Samsung give this option for nerds, that you have to use it.
[Samsung Galaxy S23 Ultra] amirage:
So the long story short is it's OK to keep charging to 100% every 2 days?
[Samsung Galaxy S23 Ultra] oryanh:
Yeah, I totally agree... just thought it was funny. Sort of like how some keep old phone screen protectors on, all peeling and scratched, in the name of keeping the screen preserved while they can barely see through the protector. :-D
[Samsung Galaxy S23 Ultra] matushsvk:
Tried it yesterday but it didn't work. Routine was running, as I've checked, but it didn't turn off Protect Battery setting after set time. Any idea why? Was this because Night/Sleep Mode was running during Routine?

I want to charge my batery slowly at night is possible to set this slow charg like oppo or not ?
[Samsung Galaxy S23 Ultra] Fl1nt91:
Is possible to set slow charge, and limit max charge to 85%.

Also, if you play with Samsung routines, you can create a routine that do what you want (like enable 100% charge 30 minutes before your alarm)
