[WORKAROUND][SamPWND] Charge to 100% Snapdragon Root

[peachpuff]

That's the thing, The 800 value has nothing to do with percentage. It's variable across devices and its coincidence thats its 800.

That I know, it's the * 1.2 that is incorrect, someone else already pointed that out too.

One thing that I didn't get.

Okay, the phone will think the maximum is 1000 and will try to charge the battery up to 800, which is the real target. Great.

The screenshot, though, shows the indicator on the notification bar close to 100%, in the rooted phone.

So, the routine that checks the phone charge and limits it to 80% is independent from the check embedded on the indicator charge, right? Otherwise the indicator would never reach 100% even on the rooted phone, and even though the battery was actually 100% charged.

What you are seeing is after I did step 3b; this shows how the percentage is reset.

I don't want to turn my galaxy s8 into a note 7...

This is just to change the number in your status bar.
You can change to whatever value you want but if you plug your phone in, it's still discharging.
Again, this does not work.

Wrong, this tricks the kernel into thinking you battery capacity is larger than it is. If you do steps 1, 2, and 3a it will still only show 80%. But the battery will charge to 100% of its capacity.

You're wrong.. Actually.

Set it to whatever you want.. I made mine 95% and plugging it in, it's discharging.

this doesn't trick the kernel, this tricks the user.

EDIT: sorry that sounded condescending, wasn't my intention. My bad dude.

But step 3b is to undo what you just did, right? Indicator will show 100% but if you use your phone and it gets down to, say, 400 (whatever are those units) and tries to charge it again, it won't go up to 800.

Then it would make sense.

 

[elliwigy]

mine wont even change visually and immediately switches back to 1000 so not sure how you even get it to stick lol

 

[MINTED7]

great find! i figured it had something to do with that file but wasnt sure how it was calculated as mine says 1000 but others was different lol..

but our idea was if this was in fact the case that you create an init.d script that runs on each boot that will automagically correct it each time you reboot the phone

to add, this is also why we releaeed it as is, we figured someone in the community would figure it out!

thanks again!

actually, changing that file instantly changes back to its original setting for me

yes mine is 1000 too and it changes back to 1000 when I change it.

That's the thing, The 800 value has nothing to do with percentage. It's variable across devices and its coincidence thats its 800.

For example, mine was 990, so 990 * 1.2=1188.

Regardless of that, this does not work. Mine still shows 80% and completely stops at that point.

the screenshot also doesnt show the phone charging as well as he is on eng system.img as i can see security log agent and service mode in his notifications

you cannot change that file as it instantly reverts back to original number

also, you are changing a symlink file, the real path is in the soc:battery section..

the real file however also reverts back instantly for me

 

[mikeyinid]

I'm 99% sure the file you guys are trying to edit is in the ramdisk. Change it all you want, it won't stick.
*edit*
When we rooted the S6 with the boot.img we had trouble running scripts so we had to just edit existing /system files to run with a wait time. That may work here. Just need to figure out which file to use then add the code just like you would an init.d script.
*edit 2*
I haven't rooted yet, I'm OCD and 80% charge would make me crazy, I'm just throwing some things out there.

 

[partcyborg]

So this workaround isn't a working workaround correct?

 

[HanMan5000]

lmao **** Samsung for this bull****. One of the reasons I switched to the S8 was for fexibility and rooting (jailbreaking was becoming more and more impossible) and now it seems like it's the same **** but even worse with the S8. I'll be switching back to iPhone if the next one has an edge to edge display.

I've never understood why people feel the need to post these things

Cool and I've setup an su.d script to run at bootup.

sucks you still have knox installed lmao

Cool and I've setup an su.d script to run at bootup.

We've had several people say this method works and several people say it doesn't. What's the consensus? Has anyone runs battery benchmarks before and after to confirm it is working?

 

[Saythis]

sucks you still have knox installed lmao

Correction: You are right. I missed one lmao.

loooks like the whole shebang to me lol
