[Q] Turn display off, but leave touchscreen on??

I would like to have the screen power down, but leave the touchscreen active. Then I can tap/swipe the screen to return the display, instead of hitting the power button. [Note: This is only for a "docked" state.]
Also, since "Display" is always the battery killer, this could prove useful for battery savings. With the screen dimmed to 20, I'm drawing about ~500mA. With the display is off, the power draw is ~100mA. Pandora is playing away the whole time. [Note: I'm not checking the power draw often, so take these numbers with a grain of salt.]
I would really like the nitty gritty details on how the power is routed to all the components (i.e. what can be independently powered up/down, and what is on the same power bus).
Any kernel gurus out there?

To be honest, this just sounds like a not-so-good idea.
Why not just flash something that gives your optical button joystick thing an unlock function?
And if you are just using this for when it is docked, why not just leave the screen on?

So, flashing an unofficial rom is a good idea, but tweaking one is not? If people didn't try the "not-so-good" ideas, this site wouldn't exist.
I have CM7, so I have the feature... disabled. The OJ button pushes the phone "dock" across my desk, and unlocks my phone if I pull it out of my pocket the wrong way. Besides, this is only substituting one button for another.
At a minimum, it would be nice to get the backlight to <5 (out of 255, not %), but I assume a full power down is where the real power savings will come from. I just want to tap the screen to bring back the UI.

Charging + screen on + CPU active = overheating battery. (i.e. It's not good for the battery.)

No need to get defensive but I see your point.
I think he just meant not optimal or efficient but it is your phone and actually sounded like an idea I thought of a while back. I'll be watching the thread.

That was more after-work-commute mood than anything he said. I thought I caught the pissy bits (that isn't the original text), but apparently not.
So, sorry, SealDog. I didn't mean to be such an _____.
Anyways, here's another way to think about it, or just more info....
I just plugged in to AC, and the battery is at 23%. This means the charge current is at ~950mA.
With the screen off, it's putting ~800-850mA towards charging the battery (fast charge rate). With the screen on, it's only putting ~500mA towards charging (trickle charge rate), and burning up ~450mA.
Somewhere around 40-42 degrees C, the charge controller drops to ~500mA, because the battery is getting too hot. Yet, I'm still drawing ~450mA, leaving almost no current towards charging.
When it gets hotter (42-44 degrees C), the charger shuts off completely. Now, I'm just discharging the battery.
I have run into this too many times. 6+ hours on the charger, and the battery has only charged up 10-15%. Not cool. (In fact, the phone is freaking hot.)
BTW, I'm trying find every on/off setting I can (e.g. 1x/3G toggle). Mainly, I want to know what each unit's idle power is. I read about lots of battery saving things, but do they really help? Does 1x truly draw less idle current than 3G? Does shutting off wifi, gps, etc. actually save power when idle? Byrong did a nice backlight + CPU frequency examination. I'd just like to go further. I have an incomplete test built in Tasker (I have to fix the stinking task priorities, and remove all "sleeps").
My ultimate goal is to have a set of Tasker profiles that optimize power consumption for my purposes, without sacrificing functionality. For example, my mobile data choice is on or off, but off means C2DM can't reach the phone. I have plans for C2DM, so this isn't something I wish to sacrifice. But, if the screen is off and the network load is near zero, 1x is sufficient.

[Q] New Service. New Phone. New Questions.

Hi everyone.
I have 9 detailed questions below.
I ordered this phone early Friday morning, this morning(Saturday) it arrived at my local UPS store and I'll get it Monday.
I brought the white version for a penny over at AmazonWireless:
Samsung Galaxy S II Epic Touch 4G Android Phone, White (Sprint)
So anyways, here are my questions.
1.
Is the phone more on the wider-side or longer-side?
My Motorola Droid 3 and HTC Droid Incredible 2 have the same screen size, but the Droid 3 is longer, like an actually candy-bar while the Dinc2 is more wider and block-ish looking.
2.
I recently changed my home internet from cable to wifi because on Verizon, the 5GB data limit just wasn't working out since I would be using Verizon's 3g network all the time away from home and at home.
I want to be able to use my home wifi network.
Does the battery drain faster with wifi enabled?
Also, is it possible to switch directly over to wifi when I walk in the door?
3.
When using it a lot, like playing a gameloft game, heavy facebook usage, playing music in the bg, does the phone make your palm sweat from the heat of the battery or the device itself?
With my Droid 3, that was a huge problem. It would get way too hot where you would have to put it down.
4.
Of course, I'm not going to stay on the stock rom...
What roms do you suggest that WILL get through a full day on a full charge, that have minimal bugs?
(ffc WORKS, no random reboots, 4G working)
5.
Does the phone get "beat-up" fast?
Like, if I'm sitting in a chair and it's charging and slides off my lap onto the floor.
Or if it falls off my bed sometime through the night.
Or putting it in your pocket?
6.
How's using the phone without a screen protector?
One is being shipped but won't get here on the same day as the device.
7.
Does the phone collect/build-up lint from your pocket or dust from putting it on stairs...?
Like those thin areas of the phone where you would use a card or something to get too. Or where the back cover meets the device on the edges.
8.
Can it handle market apps like Tinychat or Skype Mobile without lag or freezing?
My Dinc2 could barely handle Tinychat, but only every now and then.
9.
I have nearly a 10GB music library on my PC, but only own a 8GB microsd card.
Should I use a cloud service like Google Play since Sprint is Unlimited, then use the microsd card for HD gaming storage and movies?

all i can say is, this phone is awesome. Too lazy to keep answer all questions but from what i remember what i read, id recommend a screen protector. Miijahs rom / AOKP / CM9 / any venum ROMs are good. Stock: caulk/sfbhub (sorry if spelled wrong) / blazer rom. The phone does get a little hot if playing games but not too hot, but then again i use an extended battery (qcell "4100" mah). Get a case, and video is awesome on google talk dont know about other 3rd parties.

Honestly I'm willing willing to put my money on the line and just tell you. Take all your questions and trash em. You won't have problems. It full fill all your questions with a little extra. Just use it for a week without thinking constantly how's my battery and you'll realize its really superb. Stock I get 4hrs screen time. And lil more rooted custom rom. I've had it since release day and I'm a heavy user. IMO it doesn't need a case. It can handle 10ft drops on concrete. I know since my father drops his almost a dozen times

Agree with the others I love this phone. As far as wifi turning on at your door, there are different locale apps but they drain battery. The best for wifi I have found is "Y5
Battery saver" it remembers your preferred wifi connections and turns wifi on when in range of them. It did not drain my battery at all, the only downfall was if you want to turn wifi off in your home, you also need to turn Y5 off too or it will turn wifi back on.

1. Longer side
2. With 3G stock can support, 4G you manually have to change or get an app to do it.
(3 & 4 I don't know enough to reply, my apologies!)
5. Heck no!
6. Good for me so far
7. Not that I ve seen yet
8. YES
9. Why not just get a 16/32GB card for cheap? Cloud means data transfer - card means you have with you anywhere (even if data transfer not available)

I would recommend using Google Music only if you don't plan on changing ROMs constantly. Google said they were going to limit the number of devices allowed to access your Music Library. You can currently deactivate devices in the settings but I wouldn't hold your breathe for that to be available for more than a year.

Save Note 7 from exploding, untill replace

Save Note7 from potential exploding!
1. "Inportant" Disable fast charging under battery settings ( there is toggle to turn off)
2. Use OEM wall charger with OEM cable
3. Before charging phone close all active aplications and clear cashe
4. Before charging turn off wifi, bluetoth,nfc etc..
5.DO NOT CHARGE phone ubder pillow or in bad
Hope this tips help you guys and me

Perhaps we should also all be taking acupuncture and subscribing to new age homeopathy therapies? :silly:
If the battery wants to 'go bang' it will, no options will change that fact.

i'll just take my chances ?

I think switching off fast charging would make a difference. Ad for the rest? Not sure.

It doesn't, otherwise we would have been advised to turn it off by Samsung before the handset is replaced. Or a software update disabling the feature would have been pushed.

Samsung didn't say a word what to do untill replace, but if you read about fast charging, there says " your device will charge quickly but may become hot"

It's got nothing to do with fast charging, it's a fault in the battery that will heat up and catch fire if you're fast charging or not....

I think a lot of people are concluding that heat is the issue and will create the battery problem. I can't see any evidence that heat causes the battery fault to occur.

Well exploding battery will cause heat.... sooo XD... There probably many other component that cause it but anyone willing to force the note7"C4" to explode?

its a battery fault - the battery cells which are affecting the units are drawing too much power from the mains which in turn heats the battery past limit. i've had mine for about 4 days in the UK and three have told me "no recall or safety instructions have been given by company"
and samsung support have said "none of the problems has occured in the UK so you are fine to use and if it gets hot close all apps and place phone in cool place away from direct sunlight"
but samsung did say they were replacing phones. left details and call back will be in 7days
was on hold for 1 hour waiting for them to answer. might be quicker popping into a samsung store and asking about it.
but if people in UK need a piece of mind and wants to ring samsung the phone number to use is 0330 726 1000 *****THIS IS FOR UK RESIDENTS ONLY*****

I got a phone call from O2 earlier offering me to return the phone for a full refund or a partial refund with a different handset.
the option they didn't advise was to hold onto the phone and they will replace them when they get the new stock, they said this has been the most popular option with the majority of people opting for it, but they also said should the phone show any signs of the problem (getting hot when charging or swelling) I can take the phone in at any time for a refund.
chances are 3 just doesn't have all the info yet, but the recall is every phone, Samsung is probably still communicating with suppliers so it is likely a case of the firms are still learning then they will have to work out how to pass on the information to those affected.

I would have to say it's fast charging...or generic adapters. Because I used the original cable with a generic adapter and after charging for some time, the phone was extremely hot. As in ive never felt any phone become that hot. This was maybe in the first few days I got the phone. I saw fast charging was on so I turned that off.
I stopped using that particular adapter as well (which works for all our other Samsung and apple phones and pads) ... And it never became hot again.
I use another non branded adapter with a non Samsung cable in the office to charge and it doesn't get hot there. Doesn't get hot with my non branded car charger as well.
So my guess is it's the fast charging option. Or just that particular adapter. But so far... Fast charging off... With different adapters and cables.. And it's working fine.. And cool

the problem is 100% in the battery, nothing else in the phone is at fault.
basically when they make a battery it is done with layers of material and a catalyst (acid or similar) inside the battery is compartmented, if 2 of these compartments manage to interact with each other due to a fault in the separator you get a runaway reaction, at best you get a bit swelling or a hot battery, worst case it goes critical and fails (goes pop)
if you have a phone with a faulty battery you can play it safe and turn off options such as fast charging, but the fact is if the battery is one of the few faulty batteries in the wild you are only delaying the inevitable.
the only way to protect the phone is to monitor it carefully while it is charging as if the battery is faulty no amount of changing settings will solve the problem as if that was the case they would have released emergency firmwares by now to minimise risk.
but even then when the phone gets warm it isn't always the battery, my battery normally sits around 30-35C (even while charging) but my phone sometimes feels warm but the problem is the CPU running some times at 50-60C making the phone feel warm and not the actual battery.

Low battery, can't charge via (or use) USB-C port. Is data recovery possible?

My Pixel XL has a problem with its USB-C port and will no longer charge. The bottom of the phone gets super hot when it is plugged it, but no charge/not identified for USB transfers. Maybe a short or something who knows/cares. The device is currently off at about 8% battery. It's going to Verizon for a repair or replace. I have files on the phone (screen recordings, downloaded pictures, etc not in cloud) I'd like to recover before leaving it in Verizons "expert" hands.
Can't wireless charge with the Pixel XL and can't transfer via USB. Is there any "smarter" course of action rather than just turning on the phone and trying to blitz a cloud backup before the battery completely dies? I found something kind of cool regarding a possible transfer with the audio jack (http://hackaday.com/2010/02/01/android-audio-serial-connection/) but doesn't really seem feasible given my situation. Just wondering. I am sure if it needs a replace that Verizon will have no idea how to get my data off for me. Thanks in advance.
P.S. I miss removeable SDs.

Given your situation backing up to Google Drive would be your best bet. If you are connected to WiFi and the screen is off it shouldn't require much power. You can also turn turn off all radios and unnecessary functions other than WiFi (Bluetooth, nfc, data) to squeeze out a little extra battery. The battery also runs down slower when the phone is less hot. If you place the phone (no case obviously) on a cooling pad or on top of an ice pack wrapped in a thick zip lock bag it might squeeze out your remaining battery a little longer. While you have the screen on to set up the backup you should also turn down the screen brightness as much as possible.

I hadn't thought of the ice pack, can't hurt haha. I'm sure the booting will be what takes most of the remaining juice.
Thanks. Hopefully the mental path I have mapped out to select folders for backup is accurate

Question Pixel stand 2

My pixel stand 2 has a fan built in. The software has limited options for it's functionality. I use the phone nearly continuously as a hotspot on the stand. It gets quite hot, and I am using acca to keep charging between 40 to 80%. I suspect the pixel stand's fan isn't really responding to the phone's temperature, but doing it's own weird Google ****. If Google would give the option of 100% fan speed continuously my problem would be solved. My intention is to rule this device to MY specifications. I plan to open the device and direct wire it's fan to run at full speed continuously. My question to the community is: how to wire the fan to the existing internal circuitry to make this happen? My usual, non elegant solution would be to just power the fan from an external adapter. But this results in multiple power strips with multi plug adapters, an electricians nightmare. YouTube shows some teardowns, but no voltage pinout points.

I'm sorry to say that I don't have any advice on this. I don't even own a wireless charger, but I especially understand using one in your circumstance.
I just wanted to comment because what you want to do reminds me of things that I do all the time with other (usually, computer) hardware that I don't like how it works, and figuring out ways to keep things as simple as possible, but yeah, no idea about the Stand 2.
Good luck!

Mine is working just fine, I have acc set to stop at 70% and the stand set to max charge and the fan is running fast nonstop. Only issue I have is sometimes the stand doesn't communicate to the phone but that's apparently a widespread issue.

Thanks, I have been gleaning some information on this, will post when I get it sorted.

When the stand fails communication with the phone does your fan continue to run, or does it quit? Are you running heat generating apps while on the stand? Like Hotspot or AnyDesk?

With no connection the fan runs extremely slowly, it's following a temperature readout on the coil and I don't think it ever will run as fast as when the phone tells the stand to ramp up the fan.
I used to have an issue at the beginning of the year where the phone would just not connect to the stand at all, and I would have to unpair and pair the stand back to the phone. This happened a few times in a month but then just stopped and I haven't had that issue since.
I do know that what case you use does make it harder for the phone to make a connection. I previously was using the Google case but it is thick enough that it would not connect every so often and also wasn't good because it increased the efficiency loses and also trapped heat in the phone. Ended up switching to a thin case and it's better, but probably would be best caseless.
I don't run anything on my phone when it is charging, it's always idle.

I take the phone out of the case when charging on the stand. I rma'd one stand due to the fan would not start up unless I shook the stand. Now this new stand lets the phone get smokin hot sometimes. What are your ACCA settings? Mine are /sys/devices/platform/google,charger/charge_stop_level 100 5 shutdown (if not charging) at 5 Resume charging at 40 stop charging at 80. The reason I have the resume at 40 is I will often have the phone discharge to 50% or lower in use, and when I had resume set to 70% ACCA would fail, (when I sat the phone on the stand discharged to anything below the set resume point) the phone would discharge to 5, then shutdown, and proceed to charge itself to 100. I still have some trouble with ACCA and the phone charged to 100 in the morning even if I place on the stand before the resume point.

I think our main difference is that I spank my phone harder when its on it's stand than when I'm carrying it. Hotspot, mostly. But sometimes, other stuff, as well. Maybe the stand just isn't capable of keeping up with the heat generated.

Battery kept between 65% and 70%, charging switch supports battery idle mode and setting maximum charge current 600mA, prioritizing battery idle mode is enabled so the battery is essentially not used and phone instead is using external power when active.

Thank you. If your phone goes below 65% and you place it on the stand, will it pick up charging?
Did you enter your settings under the ACCA interface, or ACC?

Yes, if it drops below 65% it will charge at 600mA back up to 70% and then the battery will idle, it won't begin charging until below 65% which would take probably over a week for the battery to selfdischarge down to 65%.
Overwrite the contents of /data/adb/vr25/acc-data/config.txt and restart acc.

Overwrite the contents of /data/adb/vr25/acc-data/config.txt and restart acc.
OK I will paste the exact code you sent into that location and see how it goes. I assume this will automatically change the ACCA interface as well. I will probably disable it in Magisk first, then re enable the module after reboot.

I did follow that exactly did copy the changed file in root explorer, saw it change the file size to confirm it really happened. But the changes do not show up in ACCA. It shows automatic charging s witch and prioritize battery idle disabled, charging power control disabled. Do the changes made to config.txt not show in ACCA or did something else fail?

I figured it out. Had to remove all the blank spaces between lines. Removed the word code: at the top. Removed the line : one-line script sample; echo nothing >/dev/null at the end. And probably most importantly, changed the configVerCode=202206010 to my existing code number, as the program checks this on boot and rewrites the original file if the numbers don't match. According to the documentation, this is a nono, but I couldn't figure how else to make it work. It is working as you said it would with these changes.

That means you are using a different version of acc, so your mileage may vary. I'm still using the last stable release which is 2022.6.4.
Might also be worthwhile to install Kirisakura kernel as it puts more thermal constraints on to mitigate heat better than stock.
