Sorry for posting a new thread but i couldnt find any information anywhere... I am looking for a screen saver similar to the Palm Treo Pro which does not consume any battery power. here is a youtube video of it.

If not available I think it be a cool idea if someone would develop it.
That would be sweet, but what you're asking for is hardware-specific. The screen is off on the treos. If someone tried to reproduce this, the screen would have to be on, and it would be the equivalent of leaving your phone on constantly... it's an amazing feature, I 100% agree! But we need that extra layer of LCD in the screen for it to really work
it would probably be good to have the phone do this if it's on the charger but having it doing this with the backlight not active would probably cause sometime of battery drain

Hi all!
Not sure if this is isolated to the X1 or not, but I found that Batti (yes, I know it's discontinued now... but it is opensource freeware, so anyone can improve it now!), I found on my X1 that the CPU load, while charging and with "colour gradient" on, is constantly about 10-20% CPU load usage. My X1 would actually heat up (the battery temperature would increase) because of this, and not only that, it would take longer to charge up, because Batti was simultaneously draining the battery. And of course the phone was somewhat more sluggish.
I was about to un-install it, but then I decided to turn OFF the colour gradient function. BAM... CPU usage went down to 0-1%.
I tried turning off the "Charging indicator) which is simply stopping it from scrolling the bar left-to-right when it is plugged in, but that didn't make any difference.
The BIG DIFFERENCE is the Colour Gradient function. At least for the X1, i *HIGHLY* recommend you TURN IT OFF.
This problem might affect other phones as well, maybe only on WVGA (since we have a wider high resolution screen, perhaps Batti has to calculate too much to make the colour gradient smooth as it is?)... so maybe the Touch HD which also has the same resolution has the same problem with CPU load / Battery drain?
Anyway, thought I would bring this up, because I know quite a lot of people talk about battery drain while using Batti, and now I have identified the cause (and remedy) for this.
Hope this benefits others, and hopefully someone can maybe optimize the color gradient algorithm so it is not so CPU intensive!
(oh, and sometimes when we slide the keyboard out to change orientation or slide it back in, batti takes some time to redraw the bar... this also improves after you turn OFF this colour gradient function!)
Thanks!
Thanks man I didn't notic that but however I've noticed that something drains the battery very fast. Thanks for the useful info!

Yeh, I just thought I'd post this here, so that if someone is doing a search, then they can find a solution easily!
no more automatic switch off
Hello, I have a touch HD with Batti installed, and a very important battery drain since installed. I've tried to remove the "gradiant option" as you said, and it seems to be better, but thought, i remarked that my phone doesn't want to turn off its screen after 20 secs of inactivity, as i esked it to do via the autonomy settings ant S2U2 settings, so i think it can explain the battery drain too. Let me know if u have the same problems with your phones, please.
Not exactly resolved, but it's a workaround.
No more prob
OK, good for me, i think my problem was not Batti's fault, but a new transparent theme fot tf3d that disabled the automatic screen shutdown, cause since i removed that (very nice) theme, i have no more battery drain with batti re-installed and "colour gradiant" turned off. Thx for the trick, so ...
Batti discontinued? -- http://code.google.com/p/batti/
May i know how do you guys check for the CPU usage?
I don't ... I'm only talking about the battery drain.

Yes, it is, but the author made it open source, so anyone can continue it now!
Thumbs Up!!!!
Yup! This actually did the rick for me. I cant comment on battery consumption yet cause i just tried it but Batti is definitely performng better now. Screen switching is zippy. With gradient on, batti used to take forever to appear when waking up the device from sleep mode (used to show the charging purple colour) but now that is also very fast as well.
I used to think that turning gradient off was ugle but it is actually more pracical now that im using it; the battery is fully green when full, yellow when below 50% (i think) and red when under 10%, even looks neater than with gradient on!
Good job!
Thanks for the post! Confirmed that CPU usage has dropped considerably from 7-8% to 0.2-0.3%. I had switched to a different battery indicator for awhile, but happy to be using batti again for all of its other features!

Hello i got an unidentified issue with my Touch after reassembling it.
I bought a White Cover for my Touch and everything worked fine on disassemble and reassemble it. But now i got this crazy issue with my batterylife. It is not normal, the life is so shorten up to some hours without doing anything.
When the mobile phone is just idling the battery life is after 2 hours from 100% to 60% down and after 6 hours my battery is empty. I don't understand why this happen.
Could i do anything wrong on the assemble? The other thing is, that my camera stops also working after this reassemble. I can start the program but nothing happen. Tried many reboots and also formating system and installing it again.
Camera is still not working and something eats my battery
Does anyone have ideas? Thanks in advance.
Greets

When you try to start the program, does anything happen? Does it launch the program and display a black screen as if the lens was blocked, or the camera chip is not plugged into the main board? It may have become disconnected during the case swap.
As to the battery, it could be linked, it may not - I don't know I wonder if something could be shorting internally afterwards, but I wouldn't be too sure!
How old is the battery as well - it may well just be coincidence that it has come when you changed the case (although I doubt it!)
When i try to launch the program nothing happens. It doesn't show anything just idle, like i would have never clicked to open it.
I will check today again the camera at the mainboard, when i will arrive at home after work. Maybe it is this problem, that camera tries to connect and can't and eats my batterylife.
The battery is about 2 1/2 years old but worked fine before i changed the cover my phone was many days on before it gone empty. It's just curious
Now i need always the charger for my phone every some hours
Damn, i tried reassembling it again but it didn't solve my issue. My Battery is still shorten empty and camera is also not working after reseating it.
Hey stu any other ideas? I have to recharge my phone 4-6 times a day, this sucks really.
Do you think it could be caused by the cover? That maybe a piece of metal is sucking my battery out?
Recharging of my battery is also low now, it need soooo long. Please need help.
I really am still tempted to say the battery is dead.
it could be worth installing HomeScreen++ (UI) so you can see how much charge is being drained, and also how much goes in when charging.
it may be possible, on a long shot, that the battery is not passing enough power to boot the camera - who knows.
Is your battery slightly buldging as well? This is something I have noticed at my work that happens when batteries are coming to end of life - they also tend to be rather erratic and do not maintain a charge or take a charge (these are 4400mah batteries that cost £100 as well :/)
Have you read the thread in rom development as well about battery conditioning? That may help, anything is possible, right?
I took my devices apart yesterday to see if I could find something that may be shorting - but I was unsuccessful
So okey i have downloaded this HomeScreen UI and my Battery is draining 326mA/1305mW and Device is 36°C or 97°F hot. Is this okey? How much should it be?
At charging my Battery it shows +265mA/1008mW.
Battery is not bulging its ok like always.
Maybe i should buy new better battery on ebay?

Sweet jesus, my batery drain is 79mA/331mW
Something is causing some massive battery drain - What apps are you running/installed?
Stu i have normal installed programs of my ROM Onyx Ultimate 4.1.6. But it can't be any program installed, i did a hardreset and it was before the reset too like that.
It happens after i changed my Cover to White with everything except the digitizer, Speaker and LCD display them were okey.
Could this issue be caused of my Speaker? On putting it out from old Cover i broke it a little bit with a screw driver i push it to get it out and now the sound is weird the bass is warped. I ordered a new one, it still works but ****ty.
But who knows, if its not this Speaker drain so much, but why it should I am so helpless
Be interesting to see what happens with the replacement to be honest - I am really intrigued!
Not a lot more I can suggest for now - I'd still try a new battery after the speaker if there is no improvment.
How do the connections look on the speaker? Are they all clear and not touching anything else as well?
Okey i will buy a new battery for my phone, maybe its the issue, but i don't think so.
Today it is curious my phone just drain 650mW not 13xxmW anymore. But when i charge my phone, its increase again to 980mW
I will disassemble my phone today again at home and check if some metal is not correctly in the cover.
Okey i tested my phone again without the cover. I disassemble it and powered it without cover on and my battery was draining same about 1169mW.
So it is not the cover, maybe i should really buy a new battery.
Ok it did not help with the new battery. Still the same issue like before.
I bought a new mobile phone HTC desire and I am so happy about that. There is no compare with the old touch
Hmm, still trying to figure out what would be wrong if it was not related to the battery - possibly what controls it - but then that is a hardware fault.
I'll do some more thinking and see what I can come up with.
The desire is an awesome phone - one of the ones I am looking at getting soon. (Currently have a Hero as my main device and my Elfs as my spare/mess around phones)
yea desire is really awesome, i like to browsing through the market place
i think the elf has problems with the camera and this the issue for sucking battery out.
because it doesn't work anymore. when i press on the camera button, nothing happes.
no sandclock is showing up. just idle like never clicked on the button.
hi everybody, I use my s4 everyday and sometimes my phone dies before getting home. The main battery drainer is of course the screen, so I noticed that the new Galaxy S5 has a new feature, the ultra power saving mode, which above the other things set the display rendering to grayscale, which can be very useful in terms of battery life in an AMOLED screen as far as I know. I think it would be nice if there would be something like that on the S4 though, the display colours are great but sometimes you just don't need them, and they only drain precious life juice from our phone... Is there something like that for the S4? I'm not looking for something which turns itself on automatically when battery is low, I'm fine with a manual application (maybe a switch on a widget)... is there anything like that? Is it really convenient for the battery?

You can find the ported power saving mode from the S5 here:

Try C.F.lumen by chainfire. Turns everything greyscale, not just the launcher. Tried it so far, it seems to save some juice, but havent done any scientific testing so hard to say for sure
try this
this the easy step to get greyscale mode like samasung galaxy s5 UPSM on any android ,,, i hope this help

hey guys,
i tried today mirroring my navigation app to the EPD screen.
in my mind, it should save some battery, but actually checking the battery percentage, I didn't notice any improvement over just using the main screen.
what do you think guys? does it really save battery?
THX
Using the epd saves battery only if it doesn't need to be updated. If the screen is redrawn all the time then the savings are minimal if not nonexistent. Personally I habe disabled all the animations from developer settings, but mainly it depends on the app how efficient it is.
You might also want to look at this: http://m2appmonitor.com/google-maps...e-2-most-popular-android-gps-navigation-apps/
I suspect that the screen is actually not the most draining thing in the app. .. I found that with Waze my old Samsung phone would barely be able to charge even when plugged in and running the app... and you don't need that sort of power when looking at the screen!
So I've been trying to find a solution to this 5% battery screen dim/camera flash dilemma for some time now when trying to calibrate my zerolemon 100000mah battery on my note 4. I've read many forums and no one seemed to have an answer. I stumbled upon the answer today and felt I needed to share with everyone.
Go to setting/developers options and click "stay awake".
That's it. That freaking simple.
My phone is currently at 1% and my screen is bright and I have no functionality loss whatsoever.
Hope this helps someone.

Turns out it wasn't the "stay awake" but the fact that I was using UC Browser, had just watched a video with full brightness (using the left side screen slide (on screen) ) and when I exited the app the screen stayed bright.
I've not seen any other solution to this issue. But this actually works. It was a coincidence that made me believe it was the "stay awake" button. But now I have that turned off and still have full display brightness at 1%.
