Hello Everyone,
I have been asked to put together an instruction on how to correctly calibrate
your Sammy Charge battery... so here it goes.
First of all you need to be ROOTED there are plenty of roms and kernels here
for you to pick from so get the package you want Odin or Clockwork whatever you want.
-i will be referring to Clockwork Recovery Mod as 'cwr' from now on-
I am currently running IMNUTS 710 Non-Overclock Kernel and Humble 1.4.2 ROM. Humble ROM comes with a battery calibration app that you might find helpful for this task.
The kernel or rom you have doesnt matter for calibration but you must have the latest cwr witch is bundled with any of IMNUTS' Kernels.
You may have heard of the term 'Bump Charging' this only needs to be done before you calibrate (so you Chargers that are doing this every full charge, you are wasting your time). I will explain what this is if you do not know.
Here are the steps:
1.Turn your phone ON and charge it to 100%
2Turn your phone OFF and leave it plugged in. (you will notice that the battery will begin to
charge again but it will not be at 100% anymore it will show something like 95%.
3.LEt your phone get back to 100% (it will vibrate when it is done)
4.Unplug your phone, wait 30 seconds, and plug it back in.
5.WTH! it is back to 95% again!dont panic... LEt it charge again to 100% (2-5 minutes)
6.Now do it again. (unplug wait 30 seconds, plug in, let charge to 100%)
continue this until it shows 100% after 10-20 seconds on plug in. (it took me 15 times,
although i have seen upwards of 20 times)
- some users are saying that the time does not decrease to 100% while doing step 6, 20 times is good enough as all phones/batteries are not from the same mold-
7.Now boot into cwr (if you dont know how then you shouldnt be here)
8.Go to the advanced menu and 'wipe battery stats'
9.Reboot phone via cwr
(((this is where it will differ from the other posts or whatever)))'
10.Drain your phone to 0% and immediately plug it in. (others will tell you to let it die completely and shut itself off... YOUR PHONE WILL NOT LOG CHARGING INFORMATION IF IT IS OFF!!! ((I suggest you do a little troubleshooting to see when your phone will actually turn off. Mine turns off after being at 0% for a few mins. Your's may shut off at anywhere between 10%-0%. If it does shut off just turn it on again and plug it in)). Basically what u am saying is make sure your phone is ON during charging while doing these steps.
11.Charge to 100% (DO NOT UNPLUG IT WHILE IT IS CHARGING... if you get a call or a txt it is fine to use it a bit (and for clearification on 'proper charging' I contacted Samsung it is OKAY to use phone while charging (my bad)).
12.I did this full charge and full drain, plug in at 0% -ON charging, 4 times.
13.Charge it whenever you want.
The android OS logs 'battery stats' and charging habits based on a small window of use. Following these directions will let your phone lock in enough information to max out your battery life.
With strong 4G signal expect 18-20 hours of light use. If you are in a known 4G deadzone download LTE Switch from the Market, it lets you turn off the 4G radio and run only 3G. I personally turn off mobile data unless i need it and have no syncing actions automated. My best uptime was 41 hours and 12 minutes to 0%. Dont forget that all roms and kernels are different so your results will vary. If you are on your phone all the time... playing games, on the net, making calls you will of course have less time.. with heavy use i can burn 10%-15% an hour easy. Get rid of your 'antivirus' crap, your monitoring apps all that shat... it will only sacrifice your battery and it is unnecessary.
For those wondering about LAGFIX:
AlexDeGruven states-
'RFS is the bastard child of FAT and a Samsung developer who didn't understand how modern filesystems work with NAND storage. It has nothing to do with battery usage. For data access, the longer it takes to access the data, the longer the processor is waiting and running wasted cycles. The faster the data is returned from storage, the less battery gets used.'
So turn it on or leave it off, up to you.
I hope this helps everyone get calibrated.
Let me know if you have any questions.
(916) 877-4460 or forum it up!
Reserved for updates
Nice. Hopefully this will stop clogging the forums a little bit.

I went to 100% let it die. next day i used it normal and it was "ok". today my phone has been off the charge for 16 hours now and im still at 39%. Display took 80% of my battery so I'm sure i could easily idle for a few days. the whole time i had 4g and gps on. btw im at stock voltages and oc'd to 1.1ghz

Yeah display burns it up fast. And if you don't have strong 4g 4-5 bars it will constantly 'look' for a better signal where is cycles from 3g to 1x to 4g... eventually someone will write an app or make a system change to combat this.. (I hope). I wish I had the knowledge to do this and make our phones satisfied with low signal strength. :/

I am finally getting some decent life
Thanks for writing this and for all the other posts you have spread about your methods, yes I read them.
Today was my best day by far. I was 11hrs and 20 minutes unplugged today when I got home and still had 25% of my battery left. I work in a 4G market, and for the first time today I left 4G off and only had mobile data on a few times. I had 1 hr 30 minutes of cell talking ( thats a lot for me) and had my display on 1hr and 48 minutes. This is on the same ROM and Kernal CritalHits is running (with lagfix enabled).
For those of you that think you can't carry this phone around without a charger, you are wrong (glad I finally beleive this). You just can't have your foot on the Hemi throttle all day and expect to get Prius mileage.
Ya I have at least 4 bars of 4g all over my town. I saw 3g once and it changed back to 4g right away

Awesome post. I've read a couple other posts on battery calibration. They've been somewhat similar (except for the last part, like you pointed out), but not as clear.
I do have a question though: Are battery stats erased along with data and other stuff when you flash a new rom, for example? I'm just wondering if this is something you should do every time you flash a new rom and require a data/cache reset. I'm assuming so, since you mentioned that each rom's battery level may vary.
Anyway, thanks again!

yes, every time you wipe data, cache and delvik...recalibrate. Good method. This was the same method posted a year ago or so to help the Dinc get better battery life.
If the battery is properly calibrated shouldn't it make sense to only have to bump charge once?

There's a problem with your process, and it is step 10. Some Charges will shutdown prior to hitting 0% battery level. I've seen my Charge auto-shutdown at 5%, 3%, 2% and 1%.
Also, I don't see the point of letting it drain to zero then charging it back up to 100% without any use. One more thing, you didn't specify whether you wanted the phone off or on during step 11's charge process, but I'll assume you want the device on considering the fact that you mentioned getting calls/texts.
OP, please explain comments about lagfix
What does "lagfix" do? Are you saying that it causes the battery to be used at a faster rate?
I thought lagfix involved making at least some of your on-phone partitions into ext4 rather than Samsung's format.
Thanks for the clear instructions, it includes a detail that makes a lot of sense, except wouldn't the phone shut itself down gracefully when the battery was gone, saving the battery stats?
Rooted -- Calkulin's Stock "Battery Saver" ROM -- Xposed Framework -- a few mods from XBlast Tools running.
First off, a Root Explorer search for com.android.systemui returned nothing.
What is com.android.systemui? I don't think I saw this in my usage until a couple of days ago.
Why does 31 seconds of CPU and 1 second of keep awake = almost TRIPLE the battery use of 12 minutes of screen-on time?????

It's the actual System User Interface. So most likely a combination of the rom and xposed are causing this. Also, dirty flashes of ROMs can cause this.
If you installed a new xposed module and noticed a battery drain the uninstall that module. Otherwise remove other xposed modules. You could always try a frew full wipe in recovery as well.
I have had this issue with mostly with dirty flashing which is my queue to do a clean flash. It's also possible if you restored any apps with data, like from Titanium Backup, could potentially cause this as well.

you got caught up in a lie, with buzzwords that are pushing for you to use the rom. theres no such thing as a battery saving rom. all those scripts/mods being used in the rom are just buzzwords. battery life is all dependent on how you personally use your device, how you set up your device, and your data/phone signal quality. a rom will not save you battery.
Thanks for the help, Tom. A visit to recovery to wipe caches and fix permissions and a reboot caused this -->
simms -- I do understand that. I am not really disappointed in my battery life -- and it doesn't seem to have changed much in the week that I've had the phone. But the reporting of it had, and that sort of alarmed me...

wow, your android system is high, even though only 10% battery was used. a reboot might fix that though. you might have to go through your settings and setup again, disable stuff like google location reporting/history(it wont disable your location).

I'm beginning to think the issue I'm having is in the reporting -- not actually a battery use problem. I've only had the phone a week, so my data base is small, but I haven't really seen bad battery life nor any real change in it. Even with some use and a bunch of time fiddling with the mods and stuff, I've yet to go to bed with less than 50% left. Mostly, more...
Here's the latest pics. com.android.systemui is back on top in the overview with 36% The detail page shows 39% and a whole 2 seconds of CPU. That just CAN'T be right...

Which battery graph? You mean the current usage graph I showed in the OP, from Battery Monitor Widget?
Re Bluetooth: I just leave it on, so when I step in the car it just connects to the car. No muss, no fuss, no bother.
I suppose I could try turning it off and see how much battery I save. I know with my previous phone (EVO4G) the point at which I started leaving the bluetooth on all the time didn't change my battery life to any noticeable extent.
Here's battery monitor widget current use. The EVO idled at 70 - 95 ma. This one does seem to draw a lot more at idle. I don't know what's "normal."

Not very interesting. It keeps resetting, every time I plug in to USB to transfer the screenshots to my mac for posting here. I'm not leaving it plugged in very long -- I just move the pics and unplug it. I unplugged it this morning at 7:30 AM. It's now almost seven hours later and I'm at 93%. That ain't bad. It's a gradual descent -- no big drops like the one in your post.

Mine stats those are from my nexus 7 2013, Sot of around 4 and still 55% battery left.
I just showed u for sample. A simple restart should fix as simms told
I m on stock rom with x blast tool never happened with me....u can try to use ur phone in safe mode and see...I know its a system app but u can give a try with bluetooth off. Or flash a diff rom and see
If your phone is vibrating a lot and you have extra UI elements installed this seems normal.
When you only use a small percentage of the full battery smaller drains appear large.
Bit off topic, but have you thought of using WiFi to move your files over? No messing with the wire and you could even automate the task.

Hi everyone !
I haven't seen this info anywhere on XDA, at least on this forum, but i think everyone should know this.
Not trying to take credit in any way, because OP made a terrific job at researching and testing, just wanna spread the knowledge.
Basically : Charging your phone at night or leaving it charging even while at 100% for a few hours will have a big impact on how it behaves and how your battery holds up.
Quick explaination : Since Nougat, you don't get the App Optimization screen anymore on the first boot.
That's because Google has delayed it, and it triggers only in specific conditions : When the device is idle, fully charged, and still plugged in.
This optimzation allows to build the ART cache, which speeds up the system and apps, saving CPU power because it avoids using the JIT (Just In Time) compiler, thus, saving battery juice.
This also means wiping cache isn't going to help with your battery life, quite the opposite.
You'll see he made a test with other users, and the results are quite clear.
Here is a link to the post with detailled explaination and testing, thanks a lot to anupritaisno1 for all this info :
https://forums.oneplus.com/threads/...-and-battery-calibration-myths-busted.993896/
Forced the building through "cmd package bg-dexopt job" on my own OP6 running Pixel Experience, took like 15mn. SOT improved quite a lot.
Interesting read, thanks
What if you charge it at night while the phone is OFF?

If the phone is OFF it can't trigger the optimization task, this won't be beneficial.
In the article he actually made a test about this, you should read it !
Interesting, but... who claimed that clearing the cache helps with the *battery*?
Also, what happened to the old adage "never leave your phone plugged in" because it causes battery wear?

A lot of people claim this, that you should clear the cache after an update, without clear reason why. At least we have a reason not to.
And this old adage is indeed old, like the "Fully discharge it for calibration". We're not in 2002 anymore. Modern technology had the nice idea to remember to stop the charge, and use Lithium batteries haha !
Leaving it plugged at 100% is not causing any wear. The post mentions a response from an electrical engineer, saying the battery is in fact on stand by and the phone is running off the charger only.

That's just one way to read it. Leaving it plugged in does not, indeed, mean that it keeps trying to charge. But once it goes down, it will charge up again. Also, supposedly, the fuller the battery is when charging, the higher the temperature and hence, the wear. Cannot attest to that, that's just how the argument goes.

Indeed. But from the looks of it, and what i've read in other places, it waits for it to drop a bit. If the battery is not used, it won't fall to 99% in a night, and won't be charged again until you unplug it. Kinda like when your phone is off. It's gonna be a long time before the battery goes down on it's own.
Interesting, gotta try it.
Still, does the <50, >70% not apply in terms of battery wear? I mean, even for straight-forward charges?

I'd say yes, it still applies. It's a different topic ! Everithing said here is related to software and charging control, when this is more related to battery chemistry. But you're right, it's still true.
To sum it up :
- Charging above 70 or 80% and discharging under 30% (Thoses are the values i read about) is indeed not the best thing for your battery health on the long term.
- BUT, the superior battery life your phone will get with these app optimizations easily counter-balances it. If the phones lasts twice longer, it means 2 times less chaging cycles required, when you think about it (Ofc not accurate, but you see what i mean)
Best thing you can do, if you really want to get the best of both worlds, is staying in between those ideal values, and triggering the optimization manually via the Linux Terminal Emulator
Although, i don't think i'm not personally going to bother, i'll just charge my phone, use it, and charge it again in the evening.
Two days after triggering dexopt manually, without flashing or changing anything, using the phone the same way, i went from 16h idle/2h SOT at the end of the day with 50% remaining to 20h idle/2h15 of SOT with 70% remaining, that's quite a drastic improvement.
Ooh can you share more?I tried googling about triggering the optimization but came up empty...
Yes, that's logic in that, if optimization is so dramatic!
PS I meant 80, not 70, just as you mentioned.

Yes, it's hard to get an info about this, wierd.
Run any terminal app on you phone, type "su" to ask for root permission, then enter "cmd package bg-dexopt-job" (without quotes).
It will run for a certain amount of time (between 10mn and more than an hour, depending of the number of apps you have installed).
When you get the shell back (A line appears under the last one to enter another command), it means it's complete.
If you wanna be sure, run it again, it will finish very fast, because the cache will be up to date (It still checks it, so it's not an instant completion).
Do it plugged in the charger, but with like 30% charge, maybe on USB so it doesn't get to 100% too fast, to avoid the awkward situation where it overlaps with the actual automatic background process doing the same thing haha
The phone can heat up a bit because the CPU is working quite a bit.
You can also run the command through an ADB shell on a PC, if you're not rooted.
Or just leave it charging during a night for once, works too
Best way seems to let if charge for the night regularly though (Quote from the OP) :
"I just say overnight because the device being idle is a condition for the optimisation to begin
Also the optimisation is profile guided. If you were to AOT compile your entire base system it would take 4-5 GB off your storage and that is just the base system we haven't even considered the apps you'll install. Since optimisation generates huge optimisation files it is more sensible to only compile what is slow for JIT to do at runtime. This might seem weird but it takes the cache size down to less than 1 GB on most devices
In other words every time you use your phone the runtime sees what is slow and queues it up for optimisation the next time the condition is satisfied"
Wow. This should be pinned somewhere!
I'll do it in the terminal just for fun, but will also leave it (for my first time ever) overnight too.
Thanks, man!

I think everyone should read this yes, even if it's just for the sake of knowing how things really work.
And i can confirm again, my battery life is so much better ...
A few days ago, going to work, listenting to Spotify on my motorcycle for 20mn, and checking my mails for 2m got me to 96% battery.
Yesterday, and today, same routine, an an hour after that i'm still at 100% ... That's very impressive.
Really interesting.
Sadly the command does nothing on my device.

Are you sure ? It doesn't display anything, that's true. But you'll know it's over when the shell returns.
Or you can juste leave your phone plugged for a night or two, same result.
My battery goes from 100% to ~97% within minutes without using it after unplugging the phone from the charger when charging overnight.
Why is that and how can I get rid of it? It occurs since a few days on custom rom as well as on oos now again.
Been having really bad drain issues on standby so decided to experiment. I've possible cured my phone from the drain issue. It involves an 18 watt charger and the usb cable (obviously). First plug your phone and charge until it says full in battery app. Second switch off phone leaving it on charger, wait another 5 mins just to make sure the phone reads the battery as full.
Third, now press vol up and vol down plus power button together keeping hold of them until the phone reboots at least 4 times, wait for to shortest reboots and let go, power up and wait for battery to say full and then wipe the device health services app completely including the ambient light data.
Reboot again if you want to while your still plugged into charger and wait minimum 12 hours like a new battery should be charged
Hopefully you cured the idle drain, if not,try install the device health services beta app on apk mirror and wipe the app again, hopefully that should be fixed, if not then your issue is completely different to mine.
Also make sure that you don't have any sound connected apps that are jamming the on the sound in background. If you did it right you should notice a clean slate in the battery app with the amount of days the phone was built or preset.
Mine said last full charge 55 days ago.
Cannot be done without charger and cable.
Or you can just reset device health services without doing the button press, i just wanted to start a fresh.
Just an update, my phone is 38 hours in with 45% battery.Just idle with minimum use, a few phone calls and updating of apps, half hour screen on all activity. Now i would say this is miraculous considering the phone was draining 1% every few mins. Even a factory reset and ota didnt fix it. PLease be aware that im not providing a miraculous cure for everyones battery drain, and not responsible if it doesnt work for you, i think a few ppl will gain from it aswell as few ppl wont gain from it. LET me know your experience after trying.
From what i can gather device health services wasnt working as it should and was killing my battery.
This looks like witchcraft. What is rationale behind your spells?
BTW, if you reboot the phone 12 times, you might get 3x the battery life. Even better, then charge it for 48 hours to get 6x battery life. I think we're on to something, but I am not sure what it is..?

your funny, look it up. Theres a bug in device health services, causes the phone not to sleep properly, the other part of holding the buttons returns the phone back to factory preset calibration, hence hardware. You will see when holding the power buttons normally it takes 10 seconds to reboot, still holding the buttons it will cycle faster on the next reboot, i suggested 4 times to make sure its done. If try it without the charger and cable, it does nothing, wont even reboot.
The 12/24 hours i mentioned is to charge like you would a brandnew phone.
No one has to do it if they dont want to, im just sharing.
If i was conning ppl xda dev would of removed it or flagged it.
Im not pushing for extra batterylife, normal operation is what i was looking at.
Ive updated the device health services from apk mirror, now battery drain is back. That just proves my theory of the app bugged up. Have to reset the stats again and hope it fixes it, again.

ive had no look in using the playstore device health services, battery is back to draining 2% every few minutes, the latest version on apk mirror or the beta are the only ones that work properly, battery stats wont even populate on the main battery usage tab. just says unavailable. So, if anyone as got the issue where the stats dont show on main battery usage , download the beta or the latest device health service app, install it and reset the battery stats. Hopefully the stats will show and drain as gone. Ive had best results in the beta.
This the latest version, not reset stats yet, just wanted to show what stats weren't showing untill I update the app.
This what you get when battery stats are cleared
This is an example.
what does your battery app say for screen on and idle time on full battery?
This is the dumbest thread a long time. What the actual f**** you're talking about? Uninstall that crappy Cloud app that runs for 12hrs and draining you battery. Look at your own provided screens.

The cloud app as got nothing to do with what i'm doing, it doesn't drain my battery. The screen shots are examples. I could as easily say your post is the dumbest post i've seen in a long time, as you don't even know what i'm on about. 1% of my battery in 12 hours is not draining the battery. Easiest thing for you to do is just ignore this thread.
This is my idle state usage after clearing stats and unsticking device health services

Its idle state, not use the phone state. The infos there for idle(not using the phone) state. There was only one app in app usage tab, carrier settings used 3%,if you turn on wifi the carrier settings doesn't use battery at all, total usage was screen, idle, carrier settings and playservices.
You can tell when device health services is stuck, the phone is always warm, never cold. Hoping android 10 as fixed it, but i doubt it.
Do you still have this issue? According to AccuBattery my phone drains about 5% per hour.

Not now, seems to have solved it. If you wish to try it, after you done the steps on android 10, open app usage tab and look on the graph to see if phones gone back to factory state, it will read something like 20 or 30 days ago last charge. Keep an eye on the population of the battery app and check if phones cold in standby.

Is this supposed to show before or after the 12 hours charge? Done all the steps. 4 reboots with the buttons pressed, then installed this beta on the link below and clear the data of the app, but the battery data looks normal to me.
Link:
https://www.apkmirror.com/apk/googl...1-9-0-247950067-release-android-apk-download/
EDIT:
Forget about it. Just show 43 days at the graphic. Will charge it for 8 hours for now and use the phone like always. Will post the results.
Hi guys,
as we are approaching nearly 1.5 years since the Pixel 5 was released, I am curious what everyone's Battery Health is.
You can use Accubattery.
BatteryGuru also has it included in their app.
It will take a few charges to get an accurate reading.
I take pretty good care of my battery, by never going below 20% and only gone about 80% maybe 10 times.
I just got Accubattery on my device so I will update where I am in a little bit.
Well since I feel itt'll take a good 4-5 charges before any type of "accurate" measurement is shown, I decided to do a full charge and I'm very happy, I feel like this is at least 90% the capacity still. Right now BatteryGuru is showing 70% but I expect it to *hopefully* go up, since accubattery is showing 85%, but this is only after 1 charge.
Running Android 11 crDroid v7.15
I did 1 full charge (35% => 100%) with AccuBattery, says my battery health is 93% (3 718 mAh / 4 000).
Not bad I guess, for a 16 month old phone which I used to charge regardless to "efficiency rules".
I used stock rom, and rooted couple of months ago. And only recently switched to lineageos 18.1 and elementalx kernel so I can't tell if there's a difference.
I'll take a look at crDroid, but I can't help installing some google stock apps - force of habits.
If I see any significative change after some charging cycles I'll give an update.
Btw are you using a custom kernel?

Thanks for posting my friend! That's a great starting point, I hope that it only gets better for you!
I'll upload images from what accubattery and batteryguru are currently showing, now that I have a few charges completed. I hope to see a higher health.. but it could always be worse. I remember my htc 10 bring at like 70% at this point in it's ownership.. though Android wasn't as up-to-date with battery adaptivities.
I used to use ElementalX but since lack of updates for Android 11 I've been pretty happy with crDroid stock kernel. (Though I have used the last update that was out and it ran quite nicely before I moved fully to crDroid. So I may give it a go and see what type of battery I am getting compared to crDroid stock).
CrDroid also comes with PixelGapps installed, which I personally love. So you'll get Pixel launcher, Camera and other Google apps/goodies .
I am not a very patient man, and a few minutes reading about this rom convinced me to try it asap !
Love it so far, I really like the stock experience with easy tweaks possibilities - I also already shared my gratitude and first issues in the main thread
I'll keep stock kernel for a few weeks and share accubattery and batteryguru screenshots here, before giving a try to elementalx kernel and see if there's a difference
This is all stock with root and some modules installed. I received my device in November of the year it was released

Dang! That's awesome health! You do anything special?
Mine is down to 87% for some reason.

Just kept my battery charged between 80% to 20%
90% here. Have the phone almost since launch and accubattery since then. Don't follow the 80% rule too much. I use to follow it religiously but then read a comment somewhere that by following it, you are at 80% health effectively so... it made sense.

So after few weeks I'm 90% on Accubattery and 85% on Batteryguru. I did noticed the stats were pulled down when I charged only to 80%, so I would tend to agree...

I installed ElementalX a couple of days ago, I've let it just as it is out of the box, no personnal settings. It seems to be very efficient with battery usage but maybe too much because I don't receive whatsapp calling notifications anymore, only "missed call" once it's too late... gonna take a look on the official topic to check it out.

Thanks for posting!
I am at 90% myself actually, and noticed it actually went up from 88% to 90% when I charged it over 80% to 85%.
So maybe with all the new changes and upgrades to batteries, etc, charging to 100% is just fine?
I think it is the charging overnight for more than 8 hours can possibly be harmful.
I think I'll start charging to 90%.
Maybe try adding whatapp to battery optimization, is you haven't already to see if you start getting the notifications.

Already tried that but thanks for suggestion
About battery, I'm far from being an expert but I think it's still good to charge up to a lower lever eg. 80-90%, in order to preserve battery health and loose less capacity at each cycle. However, in order to properly measure the battery's performance, you'll have to give it a full charge or the stats will be inaccurate, as @ribogushter mentionned.
I would suggest, wipe your Accubattery and/or Batteryguru stats and give your phone a full charge from 20 to 100% and see if it impacts your health score

Darn sorry, wish I knew what else for you to try.
I think I will keep my stats in accubattery as it gets better with time, but I will charge it to 100% and see if it drops, goes up, or just stays the same at 90% health.
Edit: both accubattery and battery guru dropped a bit after charging to 100%.. down from 90% to 88% accubattery, and 89% to 86% battery guru.
I think I will probably do 90% from here-after though, I still think charging all the way to 100% all the time isn't the best, but I really don't know anymore!
I'd like to read more about getting the only 80%, I mean it's just common sense that you get actually only 60% if you run from 80%-20%, but that is charge capacity, not battery health capacity.
I do wish Google/Android had some documentation on this. Even cApple at least has a battery capacity built into its settings, and I saw they have a setting that tells if say the screen was replaced was it done using official cApple products, very good idea actually.
Also how has ElementalX been running?
I decided to flash it and see how it compares to the stock kernel in crDroid_v7.17 (Android 11)
I always loved it when I used it, but it is a little out-dated, (over a year now) but I think it's still fine.
Proton kernel is also really good.

I think it was becase I enabled data saving, and since I put Whatsapp on the exception list the problem seems to be solved. Once again, the problem was between the chair and the screen ^^

As you said, we probably never will have a 100% effective method to quantify battery health until it's native to Android ¯\_(ツ)_/¯

Really smooth, I'm not experiencing any lags or freeze, or any problem so far and battery life seems to have improved. As a pure rookie, I don't understand what would make a given kernel different or better than the other, so I tried the one that seemed to be the most popular but I noticed only afterward that it hadn't been updated for a while and that the developer is focusing on his apps (he mentioned it on some thread).
Proton kernel's latest update is also almost 1y old, I'll stick with ElementalX until next update or give a try to CleanSlate which seems to be the most active.
Btw, I guess you're using ACC? If so, which charging switch are you using?
Best way to measure your battery is to charge it with an USB tester such as UM24 or UM25 . You can see how much mAH your battery can absorb and calculate the health . Phone needs to be turned off and charged with a regular charger, not fast-charger .
I'm looking for a good benchmark for the battery , i tried Geekbench4 , PC Mark ..do you any other good ones ?
Not that I think it helps I am always on my PC and just charge through the usb-c.
charges pretty fast too, like 45 min.
I may invest into UM24 orUM 25, thanks @arcadekidflo
If you only use usb-c to usb-c you can get TC-66c , from the same company . If you also use regular chargers you can get UM-25c .

I accidentally charged to 100% again, and health went up in accubattery.
Maybe I will start fully charging..
Oh yea. One thing that helped for me for late notifications is to turn off "Adaptive Notifications"
-- It's been working for me.
some ROMs (such as crDroid) it turns it back back on after every reboot.
I just make a shortcut on my homescreen using Activity Launcher

Many thanks my friend! Very much appreciated.
Mine looks like it's around 94% - ordered it on release day, so about 1.5 years old now.
I've not followed the 20% - 80% rule, most of the time just letting the phone charge fully over night.
Maybe the 20% - 80% doesn't really make any difference?
IMO it's pretty silly to only use a portion of your battery's indicated capacity. The nature of lithium ion batteries is such that both over and undercharging can cause damage, so manufacturers don't actually use 100%, or even 80%, of their full voltage potential. The battery circuitry itself, as well as the phone's power monitor, do a sufficient job of limiting charge and discharge, so its really not necessary to do it yourself. Use your phone as you normally would, but be aware that keeping it charged all the time may reduce battery life.
