Battery Leak - Help Appreciated

Hi all.
I'm experiencing some sort of battery leak, but nothing is jumping out at me. Went to bed ~ 95% and woke up to ~ 20%.
Battery Use Stats:
Cell Standby - 44% (TWS - 0%)
Phone Idle - 45%
Voice Calls - 6%
Display - 3%
Dialer - 2%
Here is the software info:
Firmware - 2.1 Fresh Toast
Baseband - 2.42.00.03.10
PRI - 1.70_003
PRL - 60664
Running OC Widget on detect settings & autokiller on aggressive.
Using SpareParts - Partial Wake Usage - Calendar has the largest bar above Android System (yet I really don't use the calendar for appointments).
Any thoughts/tips/tricks would be much appreciated.
Thanks!
Jerry

I'm assuming you have reboot the phone?
In addition, on your OC widget what your setting for screen on and screen off?
I'm still playing with setting that best for me and the phone. However, this is my current setting for OC widget: for screen on 729600 for min and Max and screen off 245760 for min and max. I saw if I did't select differ freq for screen off, the CPU was run at same speed at screen on. Compare the 2.1.1 I'm getting average 8-10 hr of battery. I'm guessing OC might drain battery faster. Maybe I'm wrong.

Yes, I have rebooted since loading. I used the auto-detect settings for the OC Widget, but I guess that could be an issue. 8-10 hours of battery seems low to me? I was getting near 24hrs average (some higher, some lower) on Fresh 2.0d.
Here are the settings:
OC Widget Settings:
Screen On - 245760,384000
Screen Off - 245760,384000
I guess that could be an issue.

What's your awake perentage at?

Strange I have mine set higher than your for screen on.
Still battery hr for me. I know 2.1.1 I was getting at least a day an half with moderate use.
Like abcdfv said what your awake and uptime?

Up time: 20:35
Awake time: 5:57

Awake time looks good.
Try this setting on your OC widget:
480000 min and 576000 max. It may or may not help.

Thanks for all of your help.
Would this be for both screen on & off?

Screen on.
For screen off I have mine set at 245760 for min and max. So far battery life is OK. Since unplug at 7:45 AM (100%) and now it at 66%. Few calls, web surfing and facebook. Roughly 1 hr 20 mins usage of phone and 4hr 30 mins standby. I know compare to 2.1.1 it not great battery life.

Thanks - I'll try that.
So far, I might head back to Fresh 2.1.1 if this battery life stays like it is running Fresh Toast.

You could also try running RegawMod, I have had noting but good to say about the ROM so far and battery life is wonderful! I use Strict I think on ak though., stay around 60MB free ram if that helps at all.

Thanks for the help. I decided to factory wipe, wipe SD and cache. I then flashed Fresh 2.1.1 and my battery life is back to normal. Might play with Fresh Toast some more later.
Thanks for all of your help.

Is It possible to make MS reads battery 1% by 1% ??????

AS THE TITLE .............. ( for ex. Galaxy S )

No, due kernel limitations (and you cant change that, due locked bootloader). Check older threads, it should be stated somewhere.

Nope.
But it's not too difficult to get an accurate idea of what percent it's at.
Use Battery Monitor Widget which uses very little resources and have it display the mV.
Full battery is 4200mV
Empty is 3200mV
The difference is 1000mV so the math is easy to do in your head.
Say it's at 3900 mV
It's 3900-3200 = 700 which is 70% (do 700/1000% or 700/10)
So, even if the phone tells me 60 or 80%, I know that it's really 70%
To make it even easier, what I really do is I just do 9-2 and add a 0. 70 heh
And if it's 3550 you know its basically 550-200 = 350 which is 35%

It's a good app
BUT
regarding Full battery = 4200mV
My MS when battery is full = 4194mV ( after calibration )
only one single time i saw battery = 4200mV
Is it OK ?????

Yep it's ok
I wouldnt' worry about that too much

Using the voltage to gauge charge state isn't so great because it also drops under load. You can see this using BMW - set it to show two graphs and compare "voltage" with "available". Every time you wake the phone up the voltage drops.
With the extra contacts, the battery pack perhaps has a "coulomb counter" (e.g DS2740) to very accurately track current going both ways. If we can communicate with this chip (or chips) in the battery pack, we can do our own "available" calculations.
Or can we patch the kernel (binary) so it doesn't round off the percentage?

What is the CPU usage on your Phone ?

In idle mode ( Standby ) the CPU indicator shows about 20% average.
But sometimes out of the blue, it can shoot up to 100%.
( Which means a large increase in battery energy consumtion )
Current: 2 mA idle - - 325 mA when CPU at max.
Obviously there are some background apps causing this.
I understand that all these task killers and memory RAM boosters
are of no use because Android OS has its own smart way to manage
the RAM and apps installed on the phone. And it overrides these
task killer and RAM management apps installed on the phone.
You kill a running app, and back again it restarts.
But the OS subsequently shuts down the apps when it
decides it is no longer needed to run in the background.
Sort of smart management.
However it could be interesting to know the average CPU usage
and current in mA on the LG P990 when in standby mode and max mode.
Note: Before I had V20B and the idle current was over 100 mA.
After upgrading to V20f at the LG center, the idle current dropped
to 2 mA.

As far as I know the g2x doesn't have exact mah reading capability ... just "estimated "
I would imagine your in the same boat
Pin it to Win it.

Question Does Samsung overprovision their batteries in the S and other series?

I can't stand batteries that die after 4 years.
As you may know: staying in the 30-80% range is ideal. Staying under 20% or staying at 100% will degrade/age your battery faster.
I try to keep it in the 37-65% range [28% DoD/Depth-of-Discharge] -- it lasts long without sacrificing usability for me.
I've read somewhere that Samsung limits us to <93% out of the box -- so, you never really charge to 100% and then degrade your battery faster.
What's your experience been with battery longevity?
Dialing *#0228# tells you the voltage and some battery health info.

For a few years now, since I discovered Accubattery, I've keeping charges capped at 80% most of the time (sometimes you just know it's going to be a long day...).
My S7Edge battery after 5+ years it's still around 80% capacity...so the method works.
Before the S21 ultra I used a Huawei mate 20 pro...that one is still reporting 95% capacity after 2.5 years.
I don't understand for the life of me, why it's just Lenovo (laptops) and Asus (phones) that allow the user to predetermine a charge threshold....say 80% and stop once it's reached.
Hello Samsung???

Many other laptop manufacturers allow you to set charging limits, like Dell.
SONY also -- both phones and laptops.
Samsung does have charging limits in BIOS I think.

I too have been using Accubattery with IFTTT and a smart plug for several years to limit charging to around 75% or so and have found very positive results with battery life extension on every device I’ve used this process on.
Since getting my S21U in February I have repeatedly asked Samsung tech support if there can be an option added to their Bixby Routines to end battery charging. They currently do provide options for fast charging, super fast charging & fast wireless charging in their Bixby Routines. The question is, would the present hardware configuration support the addition of an option to end charging at a user configured charge level. I have never received a response from Samsung concerning the possibility of adding such a feature to the S21U.
Maybe if they received a similar request from additional interested users, they would be motivated to look into adding what would be a very useful and valuable feature to their top of the line phone!

Even if Samsung doesn't top off at100% it would extend battery life, not shorten it.
People confuse Li charging characteristics with NiCads.

I don't use AccuBattery. It isn't accurate IMO. I did buy it but it's just in my Google Play library now. And, I use Bixby Routines to notify me when the battery level reaches certain limits I've set. I wish there was a way to get these Bixby notifications to show up on my Fit2 watch.
This is easy to do if you root. I don't want to root.
Plus, ASUS and SONY both offer bypass-charging.
So, clearly, this can be done.
Samsung should add this to the Battery Guardian app as an advanced setting for "pro-users".
I already run the phone on the lowest possible settings (720p, 60fps, eye comfort shield, 70%, low power mode, etc.) and use a Bixby Routine to enable a high-quality mode (full resolution, adaptive 120fps, high brightness, 100% CPU, etc.) when I want to turn things up. I did set Thermal Guardian to the lowest setting.
I have an SD888 S21U.
Ordinarily, my Android phones die in 4 years max because the battery can't handle a simple app launch without shutting down. Of course, if it's connected to an outlet, it'll run just fine. As the battery degrades, if you draw more power/current from it, it'll fail to maintain voltage and boom: shut-down. I think this has to do with internal resistance building up from degradation.
This was "my fault" because I would leave the phone on 100% for at least 12 hours a day for 4 years straight. I also may have let it drain down to near 0 once or twice in its later years.
Now, after understanding Li-ion batteries: I'll replace my phone at year 4. But, I'll do so without having to ever worry about the longevity and quality of my battery at that point.
Also, if you buy a popular Samsung or iPhone -- you can buy a battery case 3 years into the phone's release date.

"full_condition_soc = <0x5d>;" = 93% in decimal.
They seem to be doing SOME over-provisioning.
Some people with S8s have reported that their battery longevity is superior.

Battery Life ≠ Battery Longevity
And, can you give us an example of your positive experiences with limiting to 75%?

Over-provisioning is not proper battery terminology.
You mean a topping charge?
Given Samsung's past Li thermal runaway battery melee I doubt they would do that.

Over provisioning is what electric cars do.
They cycle you in 30-80% rather than 0-100%.
Read here: Lower charge voltages prolong battery life and electric vehicles and satellites take advantage of this.

Where did you ask them? I'd like to do the same.

So you want to midrange power cycle the cell?
Samsung doesn't provide for that. On stock Samsung's you need to do it manually.
Accubattery has a audible high alert you can set.
In reality changing out the battery is no big deal once you see how it's done. Just take your time breaking the adhesive seals. Heat the rear panel first and use a little anhydrous isopropyl alcohol* to help break the bond especially on the battery.
Have all the tools you need beforehand.
Observe ESD protocols; at least have a RH of 40-70% in the room. The cleaner the better.
*never use around LCD displays as it will poison them! OLEDs etc, ok too.

Lol, I don't think bixby is that smart
I completely disabled that turdware.
I read its EULA, no way. I firewall block Samsung out of my device as much as possible.

In the Samsung Members app in Community and under Get Help. There’s also an 800 number available in the app which I called and spoke with someone who thought the it would be a great option to be able to end charging in a Bixby Routin.

Here’s two and a half years of battery history on my Pixel 2XL shown in AccuBattery from August 2018 to February 2021. It says at the top that battery capacity is still 97%, which I don’t believe can be true. But, the performance of the phone and battery is excellent. I would guess that the actual battery capacity is somewhere between 85 and 90%, much higher than it would be if I had been charging the battery to 100% instead of 76% or so every day.

Rather than change the battery -- you're better off buying a battery-case around year 3 of phone ownership. Similar cost and lower risk.

Bixby Routines and Routines+ is decent and quick.
I did disable Bixby Voice itself as much as possible.
What firewall do you use?

Karma Firewall, freeware that uses almost no battery. I don't think it's logging feature is functional in Q and above, works fine with Pie.

I have the Note 10+ and saw the repair reviews.
It's supposedly a hard fix. Nah, not the battery if you take your time. Had it changed out for $50 plus I got to watch and learn. It's charging and running like new again. Well worth the trouble.
Aging Li's are a risk that only increases with age.
My battery swelled and I was lucky it didn't damage the display. A thermal runaway also much more likely in that state.
Greatly reduced capacity (especially if it happens in a few days) and erratic fast charging are signs of a battery failure. Any swelling is a failure☠
Replace it.

100 percent cpu usage in moto g5s plus after installing android 11 pixel experience.

After installing pixel experience , although it is great and smooth too but my cpu remains at 100 percent it lowers for 0.1 second then goes back to 100 , battery and charging time are also becoming worst , I have used avast to full scan my phone and have even installed the rom 3-4 times still it's the same problem cpu at 100 percent usage can anyone help me ?
