[$1,000 Bounty] Ultimate battery saving ROM - EVO 4G General

Seeing how the biggest battery drainer on the EVO is the huge LCD display it sports, I am offering a $ 1,000 bounty to whoever can release a ROM which allows you to use the phone with the screen turned OFF.
I believe that would be the best ROM for battery saving.

Lame... close... thank you come again!

Please close. It wasn't even funny.

probably should send your check to google or HTC as they released the first rom for the evo that lets stuff run with your screen turned off...probably should define the word use better next time.

It's actually a fun mind exercise whether or not this is for real.
Input methods:
power button push (short / long)
Vol Up / Down (short / long)
Capacitive buttons (short x4 / long x4 / swipe fwd / swipe back)
that's 14 methods of input. Think of how those or a combination of those could pair up with existing software to make the phone functions work.
output would of course be speaker & / or haptic.

He means with the screen lite off

dim your screen to the lowest setting and turn off auto dim. Next get a bowflex and show that damn phone who's BOSS son.

Working on this now
I will attempt to port this from the display phone at my local store

Display on without using top button?

I have my Nexus One set to turn off the display and go into lock mode after 10 minutes. I would prefer 5 minutes, but that is not an option. I have owned the phone for about a month, and absolutely love it, but I have noticed that the top button (which I press to turn the display on) is no longer working as well as it use to. I have to press down on the top button fairly hard to get the display turned back on. I am guessing the wear and tear of pressing the top button dozens of times each day is slowly causing the top button to fail. Is there a way to set the Nexus One display to turn on by pressing something other than the top button on the phone? Perhaps press the volume button, or press the screen to get the display to turn on, instead of the top button?

There's a fix for this.
hopefully there is nothing physically wrong with your phone.
If you have a custom rom and if it is slow it may make it seem like you have a physical problem with the button.
I've just started having this power button issue... Hard reset made no difference so I'm thinking it might be hardware related which is a shame.
HTC says return the phone for repair (had it for 3 weeks) and within the same breath without any prompting said, "And in case you're wondering you won't get a courtesy phone".
Bofslime, are you suggesting there's a specific fix or merely to ring HTC?
The top button still works, it just takes a little bit more effort to get it working. I gotta press down a little harder than I use to.
I am quite dependent on this phone, and have ABSOLUTELY no interest in shipping it back to HTC or google so they can spend weeks fixing a minor issue.
I am really looking for a way to turn on the display without having to press the top button.

Sorry, in case it wasn't clear, I've had my Nexus One for three weeks (so over the 14 day replace period I'm guessing). HTC actually said it would take about 6 days to get it back to me. Which isn't bad really.

Yes, the phone needs to be repaired/replaced.
I had my phone advanced replaced without question or hassle because of dust other the screen. Sold my G1 2 day's before receiving my N1, its not the end of the world to fall back to a backup phone. My sidekick was happy to serve me again for the interim.
Ah ha!
I have found a couple of applications which will allow you to wake-up your Nexus One display using a button other than the power-on button:

Nexus S power button conspiracy theory/oddity

My power button has been malfunctioning for about 2 months now. That isn't to say it is 100% dead, but at times it'll work if I smack the button about a few times, and sometimes it will be completely unresponsive. I have read up on the subject and found a thread with a response from a guy claiming to be an engineer who said the micro switches they use in these phones are somewhat weak and only work for a limited number of presses. Recently, I changed roms, and to my surprise the power button worked great for a short period of time. Since then, I've found that when my power button starts acting up, wiping the dalvik cache put it back to normal. This lead me to thinking, and I've come to believe it could very well be a hardware problem that is meant to happen. I am by no means a coder/programmer but I have studied it enough to know that certain code can be written for a device that sets a "timer" for a piece of hardware to die out or malfunction. If that's the case with this, then it makes sense somewhat that wiping the dalvik cache resets this timer for a short time. Anyone have any thoughts? Am I crazy tinfoil hat wearer or does this make some sense?

I AGREE! I thought it broke a while ago but I did a complete wipe and put a brand new rom on it. Heck I almost sent it to Sammy but for some reason it stared working. I dont think its the dalvik cache though. I have a feeling its ClockworkMod Recovery because sometimes it says a key was disabled and I had problems after that. I couldnt lock my phone.

well, you solved your own theory in your statement. since when does smacking your phone equate to a software issue? my power button went in august, mostly. it started showing the behavior that you described about 4-6 weeks beforehand. i say mostly, because the physical button doesnt work anymore(rarely a response from it). but ive figured out how to work it to my advantage/needs. i can wake my phone by shaking it now, and put the screen to sleep. also can be done with a light smack in the right place on the back of the phone. but to be practicle, i remapped my search button to use as a power button and wake my phone with the volume button. really, the only hard part is navigating in the bootloader menu since the volume buttons wont work there with the power button broken. so ive learned to work it by lightly, very lightly, tapping on a certain place on the back of the phone near the power button. this "loosens" the volume buttons and lets me navigate the menu. then i tap the phone again to make a selection. this in no way indicates a software issue/conspiracy to me. when it just started displaying this behavior, i thought it might be a software issue too. but it turned out to be all physical damage.
You know, the funny thing about when it stops working is that it's never all at once.
It's a degrading process of malfunction until it takes repeated button pressing, not so much force, to work. After that it works so seldom that I'm forced to do something about it. It's for those reasons I think it's something more than a hardware problem.
From your experiences, even after a full wipe/new rom installation, your power button still doesn't work, if only for a brief time?
P.S. The new touch based recovery from team win works really well for those of us who can't use our power buttons

Hmm my guess is that there are multiple issues that result in a malfunctioning power button. Props to remapping your search button to lock your phone. It would be a great work around if my phone ever had this problem again. Have search to lock the phone and volume keys to wake it. I'm unsure how you remapped your search button though. Maybe you can tell me how?

Agreed! If you have no access to a computer with adb/fastboot control the touch ClockWorkMod recovery would be very useful.

ive been using twrp recovery for a while. even the non touch version has a no power button option. but i dont believe that theres anything else but hardware issues here. it is a degradation. at first it comes and goes, later it mostly just comes( ) and doesnt go. i can even hear a slight rattle in the power button area now if i shake the phone.
about after flashing.. at first, 50% of the time it would work after flashing, but it was just coincidence. but now no. btw, i flash many times a day, even then when it first started acting funny. flashing, wiping, it just doesnt make a difference, its coincidence.

ButtonRemapper app, available here on xda for free http://forum.xda-developers.com/showpost.php?p=9399440&postcount=1
you want v0241. i have all the power button functionality with my search key except waking the device(volume rocker wakes my device). short press screen off, long press power menu, long press plus volume down for screenshots.
@tw1tchy, I totally agree it is multiple factors, which is why I can only speak for myself based on my experiences, although your overall experience seems to be similar to mine.
@simms22, I have never noticed a rattle in my phone, its likely that you and I have different causes attributed to the power button failure.
Not trying to beat a dead horse but just for the sake of being thorough, have you tried ODIN? I noticed a substantial difference when I ODIN'ed back to stock.

I really like my Nexus S, but I kinda hope this power button self destruct kicks in soon. I see it as a feature - to make buying a Galaxy Nexus easier to justify. Good looking out Sammy.
I've had a similar problem for the last 4 months or so. It started when I dropped my nexus without the cover onto concrete floor. Not good I know.
But anyway...ever since then the power button been funny. Sometimes it didn't work at all and I couldn't turn the screen off and on. It was really bad. It took a while but now I kind of know how to handle it. Still annoying mind u.
Basically with mine the trick is to press the button really really hard towards the top end and it works fine. I've also noticed what some others are saying about changing rooms and doing resets etc. It seems to help as well.
But yeah...I still love my nexus. Lol. I think by me dropping it is the reason for my problems. It probably landed badly and loosened some part of the connection in that section or something. But as I said...all Is good now that I know the trick to it.

I've had my NS since Christmas Eve 2009 and the power button completely stopped working 2 days ago. I did notice over the past few weeks that it wasn't responding properly. TBH, my NS has been through a LOT in the past 14-months (multiple impacts, spillages, kids etc), I'm surprised it's lasted this long
I'm now using the ButtonRemapper app to use 'search' as the power button. Works great! Plus my volume keys wake the phone up so all is ok.
I love my NS and wish I bought another one when CPW had them for £150 sim free!
It might be time for me to let go of the NS , just have to decide which phone is next (but thats for another thread lol)
ugh mine is under a year old. im very angry that this happened so quickly. im gonna try giving samsung a call. hopefully the will replace it. i shouldn't have to hack my phone in order to make it usable.
@rener78 You seem to have a vast misunderstanding of how sarcasm works. Just as future reference, posting dry, tasteless irony up on the internet as a smart-mouthed statement of ill will is about as practical as a chocolate teapot.
@staplebox Lol! Well played, sir or madam. I can't say posting a thread containing the words conspiracy theory doesn't grant me at least a well placed snarky comment. Although to be fair, I was kinda bored when I wrote it.
@ALL Yes, I get it, we've all dropped our phones before. I guess I expected a bit more from Sammy since my little old HTC hero that I beat halfway to hell is still going strong, while I pampered this nexus and its already giving me problems >1 year in but that's a whole different discussion I suppose.

great mine just went out yesterday... had mine for a ltl over a year now.
No tapping certain areas or anything works.
I did notice it slowly degrade over the past few weeks.
I used the fix my power button app so my volume keys wake up my phone, but sometimes after using that 5 or 6 times it will stop working too so i have to plug my phone in the charger to turn it on. Is there another way of getting the volume keys to act as a wake button??
edit: i'm gonna try out that button remapper i saw in an earlier post.

if you are using an ics rom go to the main settings, security, lockscreen.. now disable the lockscreen. you can now wake your device with the volume button. its a feature built into ics.
interesting did not know this. Thanks, I think I'm still gonna use the button remapper to change the function of the search key to the power so I can reboot and stuff and go into recovery and such easier since i'm running cm9.

thats what i do. my search button has all the features of the power button but being able to wake the device.
Here's another question what if i need to pull the battery?? I'm rooted and running CM9 what if i go into a boot loop and i need to pull the battery with no charger around (i know how to do it with a charger) would the button remap solve this?

no. the button remapper app doesnt do anything when off or the screens off. honestly, i no boot many times a week(because i test the trinity kernel as its being developed before release), ive figured out a system of light taps near the power button to let the volume buttons let me scroll, and to select in the bootloader.so for me its a non issue. to power up from being powered up, i dont do anything. a, pluging in powers it. b, tapping the back powers it when no usb is available. c, it powers up by itself usually, seconds to a few minutes after powering off.
Being a heavy user of my nexus s since July 2011, the power button died last Sunday.
One of the most important problems i had after that was that i was unable to lock bootloader before giving the mobile to samsung service, because the stuck power button caused problems to fastboot commands and the bootloater usage(menu) in general.
Finally i decided to go to the service and give the phone. The result was that in about an hour they replaced the button and gave me back the mobile. The repair was covered by the 2 years warranty and the unlocked bootloader did not cause any problem to that.
Up to now i have a "brand new" nexus s and i hope that the new button will last much longer.

Broken knock on

A few days ago my knock on broke. I've changed Rome,kernels, and restored a stock backup to see if any of that was the problem and it still won't work. Then I noticed that a line of my my screen is not registering touches. If I swipe across the area it registers, just not to touch. I have a feeling that with a portion of the screen dead it is affecting the knock on feature. Can anyone attest to this or does anyone know what my next course of action might be to get knock on back. I have included a picture of lcd screen test to show which portion of the screen is not registering touch. Thanks in advance!

In having the same issue on my Sprint G2. Only just bought this device 3 days ago and knockon with the screen off stopped working. It works with the screen on in every launcher, but turn the screen off and nothing.
I'm thinking factory reset but I came here first because it still works with the screen on.
Oh yeah, what app ate you using to see the dead zones?

Defective sensor is causing the problem. Only option is to get a replacement.

Sometimes my G2 does not recognize knock on, when I tap on the screen too fast… but this is not related to any particular area of the screen.

The app is called lcd test or lcd screen test. Just an update. The dead zone is gone now and knock on works again. It is more than likely a hardware issue with digitizer and will probably come back, but for now I am getting my knock on.

Posting from my LG G2 while driving an Evo IX.
As a temporary work around for the dead zone, I recommend installing the one handed xposed app (http://forum.xda-developers.com/xposed/modules/mod-one-handed-mode-devices-t2735815) and toggling it to shift the screen down by 100 pixels. This allows you to move necessary buttons (such as the install button in google play) out of the dead zone temporarily.
I've sent my phone back to lg to have this corrected. Seems a little silly that I have to work around a dead spot on a new phone with less than two months of usage.

Okay folks. Knock-off works, but Knock-on doesn't.
Turn off the setting in the gestures menu. Reboot your phone. Turn on setting. Power button lock your phone.
Now tap screen firmly for one second then tap firmly again. (No quick tapping like you're trying to turn the screen off)
Say this out loud. (1.- 2.)
One dot, two dot.
The first touch has to be firm and for a solid 1 second.

Well it still doesn't work. Regrettably...
I have this same problem on mine now....
I wish we could figure out what is causing these issues....Has anyone flashed TOT back to stock ZVC to see if it takes care of the issue?
EDIT:
Fix For Me:
Since Sprint doesn't have the update touchscreen driver,
Goto: Device Test-->Individual Item-->Touch Draw Test - Auto
Draw the outline as close as you can (notice the touch screen works everywhere!) then press your power button.
It will ask you PASS FAIL - SELECT PASS! (trying again if only Fail - but it worked on fail too for me)
NEXT:
5689#*980# (From Dialer)
Goto: Device Test-->Individual Item-->Touch Draw Test - Manual
Draw the outline as close as you can (notice the touch screen works everywhere!) then press your power button.
It will ask you PASS RETRY FAIL - SELECT PASS!
Exit, your touchscreen should be responding now that was previously dead.
This worked on my Sprint G2!! First time the dead zone (btw, it's always the same region at upper half of the screen, compared to other people's screenshots) happened, I thought it was the running out storage space, because after I transferred some of the photos out, it worked again. This morning, same thing happened and I moved all my photos out, leaving 3Gb free space, but did not recover. Tried the update touch firmware method, not working, but this one worked (my Touch draw test auto actually failed), but still after the manual draw test and reboot, it worked.

Sadly, it kept happening to me and eventually the method I used stopped working. I sent the phone since it was under warranty to LG. They replaced screen and digitizer. Took care of issue permanently. Sorry for bad news, but it will prob get worse till you have to replace too. ?

RIP my SGS4?

HELP.. RIP my SGS4?
Okay so I have been researching for the last week for solutions..in fact i have not found the exact same problem I have..
Samsung Galaxy S4 White 16gb Rogers
Running Lollipop that was pushed by rogers
Not rooted, nothing custom
Battery works fine on other S4's, new battery didn't help my phone
Problem: Every time i turn it on, it shows the "SAMSUNG GALAXY S4" for about a second or two and then turns off and wont turn on again until i take the battery out and put it back in...where it does that again, before i could drain any sparks left from the phone before putting the battery back in and it would turn on and i can use it until i touch the power button, where it would pop the prompt to turn off/restart device where then it would just turn off.. if it got a little to heated it would do the same. My friend is a phone technician and he said he cant find the problem...so I am hoping someone here can help me out. The battery will probably die soon and I cant seem to get it to charge.
I have factory reset it twice and nothing helped. I factory reset in recovery mode both times.
I hope everyone has a wonderful day and someone is able to help me out.. I kinda dont have a phone now Anyways, thanks.
P.S. I can upload a video to show you what I mean if you dont understand my typing lol.
My only advice is the typical one, use Odin to restore, rather than factory reset.

I had this exact same problem. It's an issue with the power switch. Mine went away after a while one time, the second time I just mashed the power button and put in the battery to see if it would turn on and kept doing that until it worked. It can also help if you just tap that side of the phone on a hard surface, maybe aim the button for the edge of your desk, but not hard.
More technical alternatives involve opening up the phone and cleaning the contacts of the power button with a q-tip and rubbing alcohol, or just desoldering and soldering a new one after testing the old one with a multimeter.
EDIT: as far a new phones go, I'd keep an eye between the Nexus phones and the Moto X Pure Edition.

My only advice is the typical one, use Odin to restore, rather than factory reset.

Yea I opened it up and looked in, the screen connector ribbon looked like as if ink or black marker was put on it and i cleaned it up and it turned on but after hitting power button it turned off... but i got it on but squeezing the screen and back near the power button when using it and it seems to make the power button work.. I got an app to lock my screen but i guess until i get a new phone i can stick with this sideline for my phone haha. Thanks tho
As for phones, I love the Nexus family haha, Moto X Pure isnt in Canada It would be to much of a hassle to get it in though i could. I really want the Xperia Z5, Nexus 5x or 6p. As a graphic designer everyone is telling me to get an iPhone tho... Ill see when ever the S4 gives out on whats in the market #Android4Life.
EDIT: I also tried the banging thing and stuff and it didnt help lol

Does holding the home button power your phone? Mine does, though it takes about 10 seconds to do so.
And please don't listen to that iPhone nonsense, why would a graphic designer ever do so?!

It powers up and shows "Samsung Galaxy S4" but goes to a black screen after seeing the logo for 2-4 seconds, i have to take it apart and reconnect everything on the motherboard, plug it into an outlet and boot in download mode and then reboot the phone for it to turn on, and the second the power button is touched, it turns off in 5 seconds. Today the GS4 turned off by itself twice and it took my about 2 hours to get it back on.
I love androids, don't get me wrong, Android>iPhone>Blackberry>Windows phone.. I chose an android over the iPhone already, twice. As of right now, performance wise the iPhone seems to be pretty good, price wise? Apple needs to die. lol. Overall I would pick between the Z5, iPhone 6+/6s+ or any of the upcoming Nexus phones. Which ever is cheaper or better money wise at the time when my GS4 fully dies off...which will be soon... is the phone ill get. Which is why I have the pole up there..
I currently use Samsung Tab A and the SGS4 and an iPod Touch 5th gen. Everything runs smooth on my iPod tho.. so I can't wait until I get either the Z5, iP or Nexus.

Anyone think i should try this??
That is my problem, the phone turning off right away

Unlock 6P when laying on Desk?

Definitely enjoying the Nexus 6P after getting it yesterday. After bringing it to work that, I have to say that it's a little frustrating having to pick it up to unlock it with the fingerprint reader on the back. Coming from a Galaxy S6 this wasn't an issue since it was on the front. Besides that I'm definitely enjoying this phone more.
I was thinking about getting a dock for it, but realizing it would be the and issue. This is where double tap to wake would really come in handy if a dev ends up figuring out a way to get that to work (if it's even possible).
I was going to try to look into making my fitbit a trusted device if possible which could help the issue. Anyone else struggling a bit with the same thing? I really like having the fingerprint reader on the back otherwise. Or anything else people are using for this? I definitely don't want to set a trusted location at work...
Thanks in advance!

are you to lazy to press the power button on the side and punching in a code?
While the phone is face up on the desk you can still unlock the phone by swiping up from the bottom of the screen and using your normal unlock method. The other option is to lay it face down and touch the sensor before picking it up.
I was thinking about not using Smart Lock because of the finger print sensor. I found it convenient to have it unlock paired to my smart watch because of this reason. I don't have to pick it up to unlock.
I Smart Lock with my Pebble Time, and a 5 second lock delay when not paired. I wear my watch when I'm out of the house but it usually stays within range and unlocked when I'm at home as well. I do find myself still using the fingerprint scanner to wake the device as I take it out of my pocket even when a PIN isn't required.

Unfortunately I've never found smartlock with a fitbit reliable. It only senses the fitbit when the fitbit syncs....it's not always connected. But for real....press the side button and punch in your pin. 1st world problems.
I turned off the finger print scanner for this reason alone. Now I'm just waiting for NRT (I'm too lazy to manual root these days) to be updated so i can root it and fix the rotation on the lockscreen and hopefully add double tap to wake as well. I normally have my phone on a cell phone stand when I'm at my desk, so its always in landscape. Not having the lockscreen able to rotate is dumb, especially in the car. I'm also thinking of just putting one of those NFC stickers on that cell phone stand at work. Just need to find the ones i have.
Dt2w is available with flar2's kernel now
Double tap to wake is available with stock kernel, as well. Just need to enable it using the code in flar2's kernel thread. Of course, this requires root.
On topic, I find myself lifting the phone up to use my fingerprint to unlock the device. Sure, I could double tap it and input my pattern, but it seems easier to just pick it up.
Wasn't trying to come across as lazy (although I'm sure I did!) Just adjusting to the fingerprint reader on the back and was trying to get different thoughts. I'm possibly going to give double tap to wake a try, thanks for mentioning that.

Dont worry about it, I don't like it either. A sensor in front is just as easy to use and unlike the rear sensor can be used without picking up the phone. Nor do I want to enter in my very long and complex password every time I want to check my notifications, use the calculator, etc. as the phone sits next to me on the desk. Calling this lazy is baffling to me, I work hard to lay out my phone out and configure it so it can perform with absolute maximum efficiency allowing me to get get to and use any application or the phone itself with the minimum time invested. Of course everyone knows they can enter their password as an alternative, suggesting it is pointless and why anyone would want to I cant guess.
For me in the most part it's a non issue because the majority of times when I have the phone sitting next to me in that scenario it's at work or at home and the phone is already unlocked. Double tap and I'm rolling. Course I knew all this going in but I had hoped I'd make friends with the rear location and that hasn't happened and probably wont. I like this phone, pretty darn solid device but its not perfect.
If the sensor was on the front, people would complain it wasn't on the back. Can't please everyone with that.
In my opinion, it's in the perfect spot. Coming form a Nexus 6 and before that a Moto X 2013, I loved the dimple and always put my finger there naturally. The Nexus Imprint is the same way. Today I forgot my Pebble Time on the charger so Smart Lock isn't active. Using the sensor is working great instead of entering my PIN. I think the placement on the back makes the most sense because there is already a way to unlock from the front (touch screen). Putting both on the front would likely mean a bigger device/smaller screen or very odd placement (off the the side of the speaker or something). The only happy medium would be putting it on the side with the power button, but that could still mean you'd wear out the physical power button using it all the time. The Nexus Imprint has no moving parts and saves your power button for the good stuff like getting into the bootloader.
I use smart lock with locations for my home and office so i don't need to unlock the phone when it's on a desk at work or at home. I also set my phone lock to 20 min after sleep and to not lock instantly when power button is pressed. I don't see the need for your phone to be constantly locked. If I leave it somewhere it will lock in 20 mins but if I'm actively using it then I don't want to to keep locking.

I do the same thing. I made home and work trusted places and use the phone at my desk without having to worry about unlocking it.
I personally use Smart Lock with my Moto 360. Works well for me.

I could never get smart location to work for me. it's really odd that yours stays unlocked at home.

I don't use it, but I've seen people say that it works better if you setup four locations directly around your home instead of just one centered on it. This way they overlap and if you're in any of them, you'll be unlocked. The very center being the most saturated area with all four circles overlapping.
