On Touchscreens where we can enable the touch controller separately from the display controller, which seems to be the case here, power draw is very minimal if you don't touch your screen. The touch controller will be napping until an IRQ is fired (aka: some capacitive input on the touch screen is detected).

If however you wear thin clothes and have the screen facing your body the permanent touch inputs will cause a higher drain.

If used in a case/pocket that has no capacitive input on the screen: Expect to loose anywhere from 0-5% over a full charge cycle.

Otherwise expect 0-30% (depending on the number of unintentional screen contacts)

YMMV

PS:

Happy to see DT2W still alive and kicking.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
This guy knows what he is talking about, as I am using his ancient dt2w-module :D

But I don't think body contact of the screen will be an issue, seeing that it is a tablet we are talking about ;)

Installed without any issue and DT2W is working excelent. I tested to disable and enable the display option and it´s running well.

Now i hope the more battery consumption is not too much. A bit difficult for me to know in the future, because i did not noticed my real consumption before.

But this tool is very confortable and a bit more consumption from 0-5% over a full charge cycle as [MENTION=4195844]show-p1984[/MENTION] reported would be acceptable for me.

Thanks once more, [MENTION=2806083]DerEineDa[/MENTION] for your good work.

But during the night I was not playing around, the tablet was "sleeping" beside my bed and during the last 6 hours I lost 4% battery with DT2W enabled.

[MENTION=2806083]DerEineDa[/MENTION] concerning battery, what is your opinion about the app battery charge limit, which i use?

https://xdaforums.com/android/apps-games/root-battery-charge-limit-t3557002/page118

i had read some about it and i believe, that can improve the battery life.

I always charge only until 80% and don´t let discharge more until 20% for rechargeing.

Two in two weeks i make a full charge until 100% to recalibrate the battery.

This app works fine with your actual LOS rom.

Hello,

I haven't been making much progress with the Oreo kernel + cameras. I will try to get some help from Qualcomm.

In the meantime, since you've all been good girls and boys, here's some candy: https://drive.google.com/open?id=0BycBHkd7fD4AdXh3MjluOHUwc2s

This is an LTE build using the same stable kernel as the F (cm-14.1-caf-LA.BR.1.3.6-04510-8976.0), integrating the patches for double tap to wake.

All hail Christian.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
I am not a fan of any kind of (battery) optimization apps, so I don't know about this app, nor do I intend to look at it :)

LOL, thanks! I am actually a bit proud of my dt2w implementation.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] tombraga:
but this is not one of the many apps which want to save the actual consumption of the battery in reducing brightness or trying closing apps etc.

This is only a limiting of the charging state of the battery, because based on statistics the life of a battery seems to be longer, if you don´t charge always until 100% full charge.

the battery for this tablet sure is not so cheap, so for me it´s important to keep the life of the battery as long as possible.

---------- Post added at 01:09 PM ---------- Previous post was at 12:56 PM ----------

[MENTION=7398554]vladimiroltean[/MENTION] This means you work on the Oreo Kernel, but only for the LTE build? And [MENTION=2806083]DerEineDa[/MENTION] can use this part also for the wifi buld? Or this parts of rom are different and for wifi must create a separat buld of Oreo Kernel?

Wifi and LTE have the same Qualcomm SD, right?

is it possible to show the real cpu-temperature (soc_thermal) in the upper statusbar, like the battery percentagem for example?

I know there are apps which shows it, already have cpu monitor and cpu-z widget installed, but i want to see it watching a film, for example in an application, without leaving the video, only pushing the statusbar down.

Not necessary to do it, I found in the app-settings to show the cpu temperature.

test DT2W enabled - disabled at night

This night i had the DT2W disabled, but big surprise in the morning:

8 % battery drain - something bad happen with my tablet

this means +4% battery consumption than the night before with DT2W enabled.

so i have to find out what happened. B

Before installing this new rom, my battery was ok, but i also installed Tuga Browser in the meanwhile, perhaps this causes the more consumption, don´t know.

I am a bit confused.

I freezed now the Tuga Browser app with Titanium Pro and will see my consumption today.

[MENTION=2806083]DerEineDa[/MENTION] : if i want to go back to my earlier rom, i can dirty flash the rom of 15.10.2017 ?

Is this the rom (15.10.) which have the earlier kernel (before you made the DT2W)?

or i can also restore the boot backup which i had made before installing the new rom?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
Yes, yes and maybe.

If the battery drain persists, I have an idea why the drain could persist even when dt2w is disabled, although this is unlikely...
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] tombraga:
ok, i will report, now i am full charging to 100% then i reset my statistic in the Exkernel Manager app, which i think gives good results. Always real results about actual consumption per hour.

do you think during today and to test the consumption, should i enable or disable the new DT2W?

In think, it´s better to disable to see, where there is other reason that can cause higher battery drain, you agree?

Hey guys,

is there a chance to implement reboot into recovery option besides the options shut down, reboot, airplane mode when pressing the power button when device is up and running ?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
I think you can enable "advanced reboot options" (or something like that) at the developer settings.

Firstly thanks for new builds and great work! Glad to see this awesome device to be alive. Secondly can i ask somebody with backup to upload TWRP for LTE version somewhere? It seems that official site is down, so i cannot download recovery to try new build...
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] Dr_Schall:
Thanks for the hint... just tried but only got into that small scroll down menu as it is when pressing volume & power button.

[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
I have no idea. You can try, but you should make a backup in TWRP before.

Isn't there some option in the developer settings that says "protect recovery" or something like that? I can't check right now. If you properly flashed TWRP using "fastboot flash recovery [file]", it can be that it was replaced by the stock recovery if this option wasn't enabled.

until now zero battery drain - nearly 2 hours, not working with it, mainly screen off

after lunch i want continue to test consumption and think to change to:

1) unfreeze the TugaBrowser app, wich i freezed this morning with Titaniumbackup Pro. Perhaps this app which i installed 2 days ago could have made my exteme battery drain? (https://xdaforums.com/android/apps-games/app-tugabrowser-t3472457)

or

2) let this app freezed and enable DT2W

which option would you suggest, [MENTION=2806083]DerEineDa[/MENTION] ?

but i remember, beside the tugabrowser i also freezed Chrome (nova versão 61) which i did not use, but chrome appeared in Greenify app this morning, that opened during night because gmail.

also freezed Telegram, which i had installed some days ago.

so in this moment i have 3 suspect apps and your DT2W which could provoce the higher battery consumption. at this moment the 3 apps are freezed and DT2W is disabled -

Decided now: Uninstalled Chrome and Teamer apps and after lunch i will unfreeze and use the TugaBrowser app, but i let the DT2W disabled for the moment.

so i will see, wheter the tugabrowser will make some problem.

Few queries, when unchecked wake when plugged option, when charging the tablet it doesnt go to sleep, screensaver just stays on and have to manually turn off screen. Next when charging with tablet off, can't 1-click and see battery percentage, no action happens can only hold the power for a period of time to boot device. Also the tablet seems to charge faster with tablet on and screen manually turn off, than the tablet being fully off.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] BlackAfghan:
I never used both at the same time, so anybody else can confirm this? If yes, AudioFX will be automatically removed in future with Dolby..

Also you can use the Dolby equalizer to remove 12dB from all frequencies in order to bring the volume down to decent levels! Than it is perfect..

KRACK is not that serious, since the attacker needs to be VERY close to you and the actual code hasn't been made public yet. So don't worry.. ;)

Official LOS? Surly not this year anymore, maybe next, maybe never..

Very low on our agenda, since we can't agree on it. LOS 15 most likely will be first, but no ETA on that either.

But for your information: it seems that it is should theoretically work with our tablet, but no actual work has been done yet.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
I am so sorry, I've completely overlooked your post!

I slightly disagree that KRACK isn't too serious. I don't want my neighbour to eavesdrop on the sick **** I watch on the internet. My last experimental build (which is as stable as a proper release) and vlad's LTE build both are KRACK-safe.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] BlackAfghan:
Well it only works when your "neighbour" is closer to you than your own router and is a world class hacker (since the details how to exploit this aren't public yet) or an government agency.

Plus everybody should encrypt everything important end-to-end anyways (and most sites like gmail, banks, etc enforce this). And if you don't do that you should worry more about anybody else in the internet listening in, than about your neighbor.. ;)

battery test with DT2W experimental rom

[MENTION=2806083]DerEineDa[/MENTION] now i have the result of my battery consumption test.

The high battery drain 2 days ago is resolved, some of the apps caused this (chrome or teamer or something else).

now it is constant < 1% per hour when display is sleeping.

also confirmed, that with your DT2W addon we have a bit more consumption (about +2% per hour). but this is ok for me, because i need and want your new addon to avoid the power buttom.

perhaps it is possible to program something similar as they are settings for Battery save to choose hours when we want that the function is disabled automatically.

I saw this in some settings of roms, that we can define, that battery saver is active between one hour and the other, for example between 22.00 - 07.00 o´clock, so battery saver is only active during the night table time.

If we would have something similar in the display settings for DT2W, so we could let it always enabled during the day and during night it is not active, what save us battery drain.

This is only a suggestion.

Here you can see my detailed battery test for DT2W addon:

[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
There is still something wrong on your side. I lost 4% of battery over an 8 hour night with dt2w enabled. But I have almost no apps installed besides the google apps.

This is not something I will ever implement in bare LineageOS. But you can do this right now using Root and Tasker.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] Tribble:
Another "works fine, confirmed" from me.

As a sidenote: Initally i had the problem that the SIM card was not detected with this build (and none of my own ports worked). No amount of wiping sytem, data, cache, ... made any difference - SIM was not recognized.

Flashing vladimirs previous build again restored the SIM function... mobile data was only working with this build.

This was so weird, that i finally

reflashed the stock OS

(Link in the top post) and going from there flashed the current LOS LTE build. This seem to have set/cleared relevant bits somewhere: Everything works fine now.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] tombraga:

[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] tombraga:
My god, i only wanted to help with my battery tests and the following suggestions, there is no reason to respond in this way.

When i made the tests from yesterday morning until this morning, i did not use the tablet, i let it mainly in sleep modus, so the consumption was good.

But today i used it normally and the consumption of the battery is signicant higher since i installed the experimental rom. I will disable now the DT2W and then will see the result, but perhaps there is some other reason yet with this new kernel which increases the consumption.
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] DerEineDa:
I didn't mean to be unfriendly. I am just saying it as it is, instead of creating false expectations. This is quite an exotic use case, which can already fulfilled by using Tasker, so I will not waste time on this.

Found a "tool" last Friday that leverages it with source code on a Russian forum. I pulled it and pen tested a few networks I set up with various access points. What I did learn is this: Not only can someone hijack your connection, but if he/she really wants to it is possible to break https and eavesdrop on everything you do, enter, receive, transmit, etc. Granted, you will have to use a few programs, show some intelligence and poke some holes, but the difficulty level is only decreasing. Once you find a "ONE-CLICK FREE KRACK CHECK" on Google Play it is way too late.

Yes, this is probably not going to happen to you, but better safe than sorry, especially since this probably has been out in the wild for years and some individual or organization have already been using it on a larger scale. (as with almost any security bug that is "found officially")

I for one replaced all access points at my brother's house with a few Unifi AC-LR I had lying around. (I couldn't possibly find a reason to put them into my network, I have enough).

Those are safe on the newest firmware. (3.9.3.7537 or newer)

Charging LED

... HI Guys,

i tried to figure out where to switch off charging LED. The steps mentioned in this thread before did not work. (Options/Display/ search for charging).

When i use search function within options it does not show a single hit for "charge". I also searched manually within every sub-menu. Whether i am too stupid to find or...

Could it be that this option is missing in latest Lineage ROM release ?
[Lenovo Yoga Tab 3 Plus ROMs, Kernels, Recoveries, ] tombraga:
I also don´t understand what happen. I would like to use the DT2W and the new rom, but the battery drain was too hight as i showed in picture.

Before i installed the experimental rom (or before the addon) i had yet more applications installed, i unistalled some apps which i used very rarely and those i suspect some higher consumption, even so i had more consumption after installing the experimental rom as before.

Now i went back to the 15_10_17 rom and my consumption returned to be normal as before. I hope there is a solution for the DT2W rom, because i think, it is a big deal for the rom.

I report this all, because you, [MENTION=2806083]DerEineDa[/MENTION] had asked for users who wanted to try the experimental rom and this what i did.
