battery idle mode?(bypass charging)

Is there anyway way to get this feature
I think it should be a default feature in android in general
The asus rog phone got it officially as "bypass charging" in a new update
In a nutshell the feature allows the phone to use power directly from the charger bypassing the battery altogether this is especially good for gamers and long sessions because u can use the phone without wasting even a fraction of battery life cycle
It can extend battery life a great deal.
After some searching I found out it can be done with a magisk module called advanced charging controller
Any chance we can implement this in a flashable zip or in a rom without the need for rooting?
It is certainly possible since there is kernels that support this for some devices and since it was implemented on the asus rog phone 3 by a software update
.. it's explained in detail here https://android.stackexchange.com/q...tery-but-use-connected-power-to-run-the-phone

This could be a very interesting feature.
For exemple I drive all day long with android auto and this could be a real life saver for the battery.

Battery idle mode needs kernel support to be possible, and this phone's kernel does not support it--not on stock (global), and not on Xiaomi.eu. ACC cannot turn on something that isn't available. And there are no third party kernels for this phone on this site. The closest thing you can do is get a low wattage charger that can only supply roughly the same amount of current the phone is using. Charging from a laptop's USB port might be suitable. This obviously does not require root, but will slowly charge or discharge the battery. The effect will be almost the same as battery idle mode, except that you may still end up charging the battery a bit while the phone is warm, which is not ideal. It should still be better than charging at high current as you would with the OEM charger and cable.
If you charge slowly as recommended above, ACC can be complementary. ACC can stop charging when your battery reaches a certain percent, so can operate the battery in a less stressful region, such as 60-80%.

It's actually possible even without kernel support
There is a generic way using acc
Here is a screenshot from the acc GitHub stable channel documentation
So it's possible
but my question was if it would be possible to implement the code in a rom or a flashable zip instead of magisk module
I'm still kinda hesitant to use magisk
I created a thread on the xiaomi.eu forums but didn't get any response

I see what you mean about emulating battery idle mode. (Though I'll believe it when I see it, since the two features described are something similar to battery idle mode, not battery idle mode itself.)
The way ACC and AccA are implemented requires root. It's the way the software is written and installed. In fact after you install the Magisk ACC module, you will see a flashable .zip in your Downloads folder. So you have the zip, but it won't install without Magisk. (I did try flashing it without Magisk.) And according to the ACC readme, some root solution is necessary (not necessarily Magisk). I assume it is possible to create flashable software that runs as root without requiring an external root solution (after all, Magisk and SuperSU provide root without depending on an external solution), but that's not the way ACC was implemented.

I see
Thanks for explaining
It can be implemented in the rom without root if the kernel supports it tho
I posted on akr-developers (one the hiirakernel thread) about the feature if it's possible to implement
Hopefully the developers will implement it

This command just stopped charging... Battery drain is still there

This needs more attention. Im also interested in it to be able this to work whenever needed not only in gaming.

H.S. power control

I don't understand this feature at all. After reading this article http://www.xperiablog.net/2020/06/01/xperia-1-iis-hs-power-control-feature-bypasses-battery-charging-to-maximise-gaming-performance/ I thought it will allow me to play games for as long as I want without depleting the battery. I've tried charging with this feature turned on 2 times now, and both times the battery level was dropping., so where's that battery degradation reduction they write about?
Furthermore, H.S. power control supposedly prevents the battery from charging, but during both tests, Franko Kernel Manager was showing that the battery was charging, not in a usual way though. Speed was going back and forth between charging rapidly (as fast as 6000 mA) and charging slowly (as slow as 12 mA).
"Limits performance reduction and battery degradation caused by device overheating during charging. The battery doesn't get charged when this feature is on. Turn off this feature when charging". So you launch a game, go through the game enhancer's features, and see this confusing AF wording, which tells you the feature prevents overheating while charging and gaming, but at the same time tells you not to turn it on while charging and gaming.

I use this feature when navigating. I was happy that it's not only available for games. Worked well. At least battery level didn't changed after some hour drive. Didn't checked it with Franco kernel Manager.
You selected the App and the colored bar appeared when App was in use?

Yes, the enhancer works, just not exactly as advertised.

I've spent quite some time on customizing the phone, installing apps etc. so I'd rather not start all over again. Unless there won't be any custom ROMs for a very long time...

it is a bug. if you still have problem. or other people have a problem there a way to fix it without factory reset. if your phone running android 12 or android 11. BUT not lasted firmware(of the android version.). try to download lasted version of Game enhancer(i recommended version 7.x.x instead version 8.x.x, because it more stable on 7, but if you rooted or can install subsystem apk, you can go with lasted version and i more recommended to do so to get more feature), subsystem and monitor apk from apkmirror, dont worry all app have same Game enhancer logo. if you have android lasted android 11 or android 12 firmware, only download Game enhancer and monitor app, as subsystem has been set to persistent app. and cannot be updated. if you are rooted download all app i mention and install as system app then reset your phone. im using xperia 1 ii with version 7.0.A.1.20 game enchaner as my original version came with my firmware have bug and H.S does not work as intended. whoever updated it does fix the problem(you can see with most battery monitor app that charging switch from -x/+x to null or 0) whoever not installing subsystem and lasted monitoring app from cause :
1.powersaver or balance does not effect anymore(but switch to Power save allow phone to use 600-700mah more often, and performance while have same usage sometimes spike to 1000mah sadly the display stay at 60hz, this is not intended as using original app power are limitied to 400-650 while average around 480mah with 40hz display)
2.while congrats you can streaming from you phone now, unless subsystem installed you may only have 1 chance to screenshot thumbnail until you reset user data. as importing image or re screenshot not working without newer subsystem. but at least all stream function working fine as i test it for 1 hours nonstop(just make use you have atleast 20-30mbps UPLOAD as lower than that cause stuttering on youtube even on 480p stream)
3.it may or may not disable/bypass thermal throttling while gaming(cant confirm but on my phone using original apk will give me around 280gips max then down to around 160 or 180gips under 5 minutes while using update version will stay more than 300gips, on CPU Thrttling, same as 3d mark, while normal benchmark average, extended test will have better result than most xperia on same model with 99.5% stability and score around 1108 to 1106 from loop 1 to loop 4 with identical performance range from loop 1 to loop 20)
4.recording no longer work on sdcard as they change folder name and older subsystem still using older name, it just keep asking permission
5.on stream and record menu. there option for capture card. it does nothing, even installing another backend app. like audio app from G.E and other app, it still wont work, unless you are rooted and install all backend app as system app, whoever fearnot, you stil can stream your content via type c to hdmi like normal, but dont except you can get audio bypass or settings like xperia 1 IV have,
*again point 3 is unclear as for me performance from older bencmark are deference than now, but it is from era android 11, i can be sony fix thermal issue and performance from firmware and not this trick, but it does effect mine since i can just remove update and see instantly the deference and it may can on your xperia too
*i said both monitoring/monitor app and subsystem app. because it called that but apk file name uploaded as sony multitasking function and GE subsystem
here a proof for point number 3, and not it not with any mod(no fan cooler but no case either with H.S enabled)

Hello,
You can add custom apps to H.S. Power Control right?
Only supported apps or ALL apps installed?
Does that also work if you turn the screen off? or does the phone start charging as soon you you turn the screen off?

Mobile devices, charge management settings

Hi there,
I am a newbie and I have read on different web sites that one have to take care of the mobile device battery to avoid hasty weakening.
For example search on your browser “mobile device battery charging best practices”.
I have some technical hardware questions:
- In the electronic charging module, is there a control to switch ON/OFF by software the power to charge the battery.
- If YES, what is the leakage current when OFF, relatively to the nominal charging current and the device consumption?
- Is it possible to control the charge current by software?
- As the devices have in stock its own battery voltage detection, is the values readable by software. I mean can the developers use them in the ROM?
- To sum up, why there is no charging management in the setting of the custom ROMs? I mean set the current and time by settings in the ROM.
Thank you to share your knowledge.

Maybe my questions are too technical. So other questions:
1- In a good working device, when it beep or lights to ask charge, is the battery at 0% + a bit OR is the battery at 30% + a bit?
2- In a good working device, when it beep or lights to say "charged, please disconnect", is the battery at 100% OR is the battery at 80%?
3- Why should one to disconnect the device after charge? What is the cycle (in time or %) charge/discharge that will damage the battery?

Here a good post that give some info but doesn't answer my questions.

Question Custom Kernel for Gaming POCO X3 PRO PLEASE

Any developer wants to make a kernel for games on the poco x3 pro? if possible, add the option to skip the battery, such as Rog 3, oneplus 7 (enabled by the advanced charge controller). Please!

You can try ask in the telegram group
MOD EDIT: Link Removed
Battery skip, do you mean direct power to device without charging the battery when connected with charger?
This thing will need the hardware support. As I personally try auto-detect, ACC didn't detect this support.
Maybe ask developers if they see this option possible in the firmware/kernel or not.

yes the power goes straight to the cell phone and does not charge the battery, it preserves the useful life, so I saw only the kernel support is enough I think

Use Advanced Charging Controller (acc)
https://forum.xda-developers.com/t/advanced-charging-controller-acc.3668427/
It's written in the README description how to "emulate" battery idle mode
​
Spoiler
Generic​Emulate battery idle mode with a voltage limit: acc -s pc=101 rc=0 mcv=3920. The first two arguments disable the regular charging pause/resume functionality. The last sets a voltage limit that will dictate how much the battery should charge. The battery enters a [pseudo] idle mode when its voltage peaks. Essentially, it works as a power buffer.
Limiting the charging current to 0-250 mA or so (e.g., acc -sc 0) may produce the same effect. acc -sc - restores the default limit.

Don't go to high on battery temperature.
Try not to use while charging.
Smart batteries now have self condition check.
Ampere app can check condition of batteries.
Try not to get battery percentage higher than 95%.
Try not to get battery percentage lower than 30%. Charge when you have access to power.

I always use the black shark cooler when I play on the charger, battery temperature at 30 C, but I'm still not sure if this idle battery "emulation" works, I saw that it depends on the cell phone kernel and I'm not sure if my phone supports it, I wanted to be sure, because I use the game charging for hours and the battery without charging can't handle

ACC did not detect idle mode support on auto, it is not support by the kernel, not even in MIUI (yet).
Only emulate.
You need to take balance whether you want battery health or gaming.
You have to choose which is priority for you.
Give and take, not both.
About kernel problem, go ask in Telegram group. Find kernel authors and ask possibilities to get idle battery mode into kernel.

doubt battery less consumption tips

What is the most efficient way to decrease battery consumption on a Redmi Note 7 Evolution X? via battery control app, Custom ROM settings or kernel replacement or other?

Turn off Wi-Fi, BT & NFC, run no apps.

it is possible to automatically turn off these functions after a few minutes the smartphone stopped without use in idle on with the display off
the only app I leave active is magisk and ACC Settings to have a charge and discharge control of my battery?
if i shouldn't use saving apps then which option has more effect on battery saving? Swap ROM or Swap Kernel?
