i have noticed that the battery metter is completely unreliable
for example it shows 28% left (btw, i installed FInixNOverBattery for percentage indication) and after a soft reset it shows 41%
or it shows 50% and after soft reset it shows 31%
in this way i can never estimate how long the battery will last
does anybody faced this issue? any solution fot it? (i also tryed to calibrate by completely drain the battery followed by complete charge withe the device turned off)
thank you in advance!
noris08,
it is completey normal to experience big jumps in % after a reboot. The battery % is just a representation of the actual voltage of the LiPoly battery, which usually recovers (rises) quite a bit when there is no load on the battery (even for a short time).
maybe what you say it is true, but i never experienced this behaviour with any of my previous phones. and i had a few, including wm for a few years
and variations of 10-15% - i find them too big
I noticed the same thing. Any explanation for this? Or it is just that FInixNOverBattery is not reliable/compatible/accurate ?
Voltage may vary/jump around due to environmental changes and power consumption or voltage sensor may be insufficiently accurate to provide reliable voltage readings for 1% steps. This is one of the reasons why many battery drivers in WM only provide remaining charge percentage in 10% steps.
In this light, voltage on its own is not a sufficient indicator of remaining charge percentage. Other parameters, such as voltage deviation and other factors, such as power consumption and temperature may need to be taken into account to obtain a more accurate evaluation.
Hi all,
One of the things that annoys me about the S200 is that the battery indicator, when charging, doesn't show the actual charge level (but instead, cycles through 20/40/60/80/100)
So, if I want to check the charge level of the phone, I have to disconnect, and then (if it is not charged enough), reconnect.
Is there any tweak that would get it to display actual charge? (All my previous WinMo phones - even going back 8 years - behaved this way)
Thanks

Check out this App. I use it and i love it. It shows a battery line and can show percentual state of battery.

Hi!
I'm trying this on Arto's 2.8 (Manila) ROM and it doesn't appear to do anything at all... are you using a Manila or non-Manila ROM?
Also, it isn't clear from the description if it will display battery level accurately while charging.. can u confirm it's behaviour?
BTW Arto's ROM already includes a mod to show battery to 1% accuracy (but while charging it only shows a charging icon - and battery settings cycles 20/40/60/80/100).
I think the issue is not in the displaying app, but some means to change how the phone reports the battery level to software (perhaps a reg mod or driver mod)

forgett this app
my mistake. batti only shows % steps. this means that the line is cutted in parts (like blocks). sorry no numerical display
While I've had many Android phones, this is the first phone that I decided to use a battery charging controller to regulate how my battery is charged. I just wanted to share my journey with others and encourage others to try this out if you are not already.
Although there are several different battery charging controllers out there (and more than one named "ACC" which makes it even more confusing) I decided to use the Advanced Charging Controller module developed by VR25. I choose this module because I felt it provided the most customization.
Step 1 - Installation
Installing the module is easy. It is listed in the Magisk repository. Simply browse the available modules and find the one titled, "Advanced Charging Controller (acc) created by VR25 @ XDA-developers". There are several ACC modules, so make sure you install the one by VR25 to follow this thread.
Magisk will flash the module and start it automatically. You don't even need to reboot, although it is the only way to clear the Magisk notification that the module will be started at the next reboot.
Step 2 - Changing the Charging Switch Setting
I found that the default charging switch setting (auto) does not work reliably with our phones. Therefore I would suggest changing it using the commands below. Personally I have choose option 2 (battery/charge_disable 0 1) but I listed all the options with the quirks that I have found with each one.
Step 2.1 - open your preferred command line app - I use Terminal Emulator.
Step 2.2 - type "su" and hit enter to gain root
Step 2.3 - type "acc -s s" and hit enter - this is the command that allows us to select another charging switch
Step 2.4 - type what number of the charging switch you want to use.
Here are the available charging switches and the issues I have found with them:
1) Automatic - this switch tries to cycle through the available switches until if find one that "works".
- Passes the ACC switch test (type "acc -t"): Yes
- Charges and discharges according to the cooldownratio: No - I found that the phone would charge anytime it was plugged in and below the Pause threshold. It did not seem to wait until the battery level was below the Resume threshold.
- Works with battery idle mode (the phone will pull power from the AC power and not the battery when the battery reaches the Pause threshold): Yes
- Begins charging when phone reaches Resume threshold: Yes
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging: ???
- Suffers from wakelock issues when phone is plugged in but not charging: It does have a "overheat_mitigation" wakelock when on the battery idle mode, but because the phone is not using the battery power, it doesn't effect battery life and therefore I don't concern myself with this issue.
- Other issues:
2) battery/charge_disable 0 1 :
- Passes the ACC switch test (type "acc -t"): Yes
- Charges and discharges according to the cooldownratio: Yes
- Works with battery idle mode (the phone will pull power from the AC power and not the battery when the battery reaches the Pause threshold): Yes
- Begins charging when phone reaches Resume threshold: Yes
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging: ???
- Suffers from wakelock issues when phone is plugged in but not charging: It does have a "overheat_mitigation" wakelock when on the battery idle mode, but because the phone is not using the battery power, it doesn't effect battery life and therefore I don't concern myself with this issue.
- Other issues:3) battery/input_suspend 0 1:
- Passes the ACC switch test (type "acc -t"): Yes
- Charges and discharges according to the cooldownratio: Yes
- Works with battery idle mode (the phone will pull power from the AC power and not the battery when the battery reaches the Pause threshold): No - phone begins discharging from battery when Pause threshold is reached but the phone is still plugged in
- Begins charging when phone reaches Resume threshold: Yes
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging: No - may show charging icon when phone is really discharging, especially during cooldownratio times and the chime doesn't always ring when charging resumes.
- Suffers from wakelock issues when phone is plugged in but not charging: No
- Other issues: The phone seems to follow the cooldown charge/discharge times even before reaching the cooldown threshold. I find the phone pausing for 10 seconds (my cool down ratio) when the batter level might be a 50% - long before the 60% cooldown threshold I have set in the config file.4) dc/input_suspend 0 1:
- Passes the ACC switch test (type "acc -t"): NO, so this switch doesn't work with ACC
- Charges and discharges according to the cooldownratio:
- Starts discharging when the phone reaches the Pause threshold:
- Begins charging when phone reaches Resume threshold:
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging:
- Suffers from wakelock issues when phone is plugged in but not charging:
- Other issues:5) battery/charge_control_limit 0 1:
- Passes the ACC switch test (type "acc -t"): NO, so this switch doesn't work with ACC
- Charges and discharges according to the cooldownratio:
- Starts discharging when the phone reaches the Pause threshold:
- Begins charging when phone reaches Resume threshold:
- Charging "chime" and battery icons correctly reflect if the phone is charging or discharging:
- Suffers from wakelock issues when phone is plugged in but not charging:
- Other issues:
Step 3 - Configuration
You can configure the ACC controller using a couple of different methods. You can do everything using command lines, you can use the beta ACC app (see note below), or you can edit a config file that ACC creates when it is installed. Personally I found that editing the config file was the quickest and easiest method to make general changes.
The ACC config file is found at /storage/emulated/0/acc The file is named "config.txt" You can open the file with a text editor. I personally use the app Root Explorer. I long click on the file name, and then press the three dot button in the upper right hand corner. Choose "Open in Text Editor" and the config file will open and allow changes to be made. Saving the file will automatically push the changes to ACC, you do not need to reboot or restart the ACC daemon for changes to take effect.
I won't go into a lot of detail about all of the different configuration options here as the developer's xda thread is the best place to get that type of information. But I will talk about the most basic setting - the "capacity" setting. It is the second setting listed in the config file and it should look something like "capacity=0, 60, 70-80". Here is a break down of what those numbers mean:
- The First Number (0): is battery level were the phone will shut off. The default setting of 0 means the phone will turn off when the battery level hits 0. Personally I don't want my battery completely draining, so I have it set at 5.
- The Second Number (60): is the battery level where the module starts it's "cool down" functionality. Cool down (listed as coolDownRatio in the config file) is where the phone will stop charging briefly and then restart charging. The default "cool down" setting is coolDownRatio=50/10 which means the phone will charge for 50 seconds, and then stop charging for 10 seconds before charging again for 50 seconds, etc, etc, etc. This is designed to keep the battery temps low. A battery with a charge level less than this number (60 in this example) will charge without pausing, but when the battery level gets to this number or above, the phone will charge and pause based on the coolDownRatio.
- The Third Number (70): is the "resume" value. If the phone's battery level is below this resume value, the phone will charge. If the battery level is at or above this resume value, the phone will not charge even while plugged in.
- The Fourth Number (80): is the "pause" value. This is the battery level where the phone will stop charging and should not charge above this value.
The default settings are set this way because research has shown that a phone's battery will last the longest with the least amount of battery capacity loss if it is charged to a max of 80% of the battery's capacity, and allowed to discharge just a small amount (10%) before being charged again. I realize this goes against the old "wives tale" that our phone's batteries have a very limited number of charges and it is best to limit the number of charges by only charging the phone when it gets to a low level. This is not true in actual battery performance however and if you charge like this, you are actually decreasing your battery's life expectancy and performance.
Obviously the default settings may not be the best setting for you. The default settings are probably only practical for a device that is plugged in 100% of the time. Personally I have changed my capacity setting to capacity=5, 60, 70-90. This means my phone will turn off when the battery level reaches 5% (something it has never dropped to yet), it is charged to a max of 90% and will discharge to 70% before charging again, and the cooldown charging cycling starts when the battery is 60% or higher. Obviously I'm not on my charger all the time, so it is very common for my battery to drop below 70%. However, if the battery is below 70% and I have a charger at my disposal, I am going to charge the phone back to 90% rather than let it the battery levels continue to fall.
Final Notes and Misc Thoughts
There are lots of other options and commands you can use in ACC. Feel free to share any changes you like to make, or post if you are having problems getting the module to work as expected on the 3a. I hope this helps some people feel give the module a try.
There is an ACC app that is available now that allows you to control some of the settings from a nice GUI. I personally did not like using it as I found it would overwrite settings in the config file that I was not intending to be changed.
There is an ACC telegram group if you want to join and have direct communication with the developer and others.
Thanks to @jellopuddingstick for educating me on what the battery idle mode does and why it is beneficial to have it working!
if you want to extend your batteries life, one of the best ways is to not fast charge it. fast charging not only degrades it a bit faster because of the amount of current, but it also tends to heat the battery up more which makes it degrade even faster too. heat is the main reason i tell people not to use wireless charging.

This is why I always use a low current charger unless I absolutely need a quick charge. I have used the Dash charger that came with my OnePlus 5 only about 10 times in 2 years.
As I use my phone more, I realize that none of the charging switches seem to work 100% of the time as expected. I'll continue to do trial and error tests, but please share if you find a switch that works consistently.

I was having issues with ACC not working before installing the apk. I'll report back if I have any issues.
Nice guide BTW.
I've continued to edit my original post to provide as much information about the different charging switches and the issues I see with each one. Hopefully it is easy to understand.
I still find myself defaulting to the 3rd charging switch option and while it can act a little erratic sometimes, it does work normally most of the time.
I'm just curious if anyone has tried the "auto" charging switch in the latest ACC version? According to the release notes, there was some changes made to the auto system as it may not have been working correctly.
I'll try it here in a little while, but thought I would ask.

I've been using the apk auto switch, no issues.
Is this working for anyone:
usb/current_max:500000
I have is set in the app as an On plugged option and It is not working for me.

The phone discharges at the pause threshold and not simply hold the charge at the threshold percentage?
I found the auto setting showed the same tendencies as switch 2 - not discharging below the pause threshold. But I haven't tried it with the new release which specifically mentioned the auto setting bring changed.

I'm on 2019.6.14-r1 version.
I charged up to 80% and kept it plugged in to see if it would drop or maintain, it dropped. It took forever.
Edit: 8 hours later and it has only dropped to 78%
@creeve4, I can't get the On Plugged options to work either. I tried "./usb/current_max:500000" and "usb/current_max:500000", I tried unplugging/plugging in the charger, resetting the daemon, still no luck. The settings were saved to the config file correctly. No idea.

Interesting. That's unfortunately not what I experience.
I just tried the auto setting and plugged my phone in and it immediately went into what I am calling a "maintenance charge". It was only charging the phone by about 200 mA. I set the charging switch back to #3, unplugged and replugged in the phone and it is charging at about 1200mA which a pretty normal charging current for me.
It's this same roughly 200mA charge that I have seen previously with the auto setting after the phone reaches the set pause threshold - so the phone charges at normal current levels and then drops to the 200mA current after reaching the pause threshold. Admittedly, I did not allow the phone to reach the pause threshold this time (which would take forever at 200mA), but seeing that charging level at all leads me to believe that the auto charging switch is still not working for me (it should either be fully charging or full discharging). I suspect because the phone was above the resume threshold it defaulted to this maintenance charge (thinking the phone shouldn't be fully charged until it dropped below the resume threshold).

That is interesting, have you tried updating yet?
I should also mention that I have only changed the percentage to 3% for the phone to shut off, the rest of the options are default.
Is anyone else getting the following message in the acc app after updating to the latest version?

I just needed to update to the latest app version. The module was updated before the app.
Did anyone else lose their config settings when updating the ACC module recently? I updated a day or two ago and woke up to my phone at 100% charge. I started troubleshooting and found that the config file was set to all the default settings. This means the charging switch was set to "auto" which has never worked for me and it explains why the module didn't pause the charging at the default pause setting (80%).
The release notes talked about a lot of changes in the config file, but it never mentioned that users would lose their settings and be reset to default. I was just curious if anyone else experienced the same thing or not.
There's a bit of misinformation / misunderstanding going on here, I think. The best control file for our devices is battery/charge_disable. The "maintenance charge" (ACC refers to it as "idle mode") you're referring to is a good thing! This is explained both in the ACC readme [1] and by the developer of Battery Charge Limit [2][3]. The ping-ponging between the upper and lower thresholds is a fallback, it's not the desired mechanism. Hope this clears things up!
