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 !
i own an nexus 4 device and i have a battery problem .
before i baught this device i read online and i already knew that his battery isnt very good , but i never taught it would be that bad !!
i barely touch the phone and thr battery keeps draining !!
my question is what can i do to make it better..maybe to replace my rom , or install another kerner...anything please help !
thanks in advanced, Orel
turn off stuff which you are not using, eg. data, bluetooth, NFC, wifi, location services;
and turn your screen brightness down as much as possible.
that's all you can do, but it should make a big difference.
also think about investing in a compact portable battery charger.
My battery life on my Nexus 4 is awesome.
Download wake lock detect to find what apps are eating up your battery.

Install a custom rom and go try a custom kernel.
DO NOT ASK WHAT ROM AND WHAT KERNEL IS THE BEST
Try all of them and see how it is for YOUR device. Try undervolting if you want to. Personally I'm running PA with Franco with a -100 undervolt. 8 hours on standby takes away about 1-2 %.
Hi !
I'am interested in optimizing battery usage/life on my Note 3.
I want to know what functions is free to switch off or reconfigure to decrese battery usage
But I dont want to cut phone functonality too much...
I'am not interested to tips like:
- switch Wi-Fi OFF
- switch Bluetooth OFF
- switch GPS OFF
- disable synchronization
- disable background data
- disable S Beam, NFC, Air Gesture, Air View, Smart Stay
- disable vibrations
- switch phone OFF when not using
- turn Power Save mode ON
- turn Airplane Mode ON
- lower down CPU/GPU frequency
Because they make phone much less usable and fun because it's many nice and amazing functions wont work...
I've already applied following tips:
- disable Google Now
- disable raporting GPS position
- disable location history
- turn screen brightness to AUTO
- remove unused/unneccecary widgets (especially this with auto update/sync)
- turn off autostart of unnececary apps (with All-In-One Toolbox)
- turn off "notifications from server" in "Samsung Apps" settings
Because i know that following tips are working and have positive impact on battery life (about 20% more power in my case)
I can't root phone (MJ7 firmware...) so I cant use Greenify to make more battery life...
If somone know some more configs/tips/apps that can be applied to increase battery life I will be very interested
- turn screen brightness to AUTO

This I believe is a myth, if anything AUTO uses more battery IMO. I set my brightness at around 40% or so and I get 30 hours (with 3-4Hours screen time) or so average out of my battery, Only other thing I disable is GPS.
It's more about how/what you actually use on your phone rather than what you can disable and not use.
I think you're looking for a reduction in "idle" battery drain as in use battery drain is kinda unavoidable.
There are tools like "Tasker" you can use to automate all the radios
you can use "app ops" to stop all the apps that push your location (this will do the most)
"autostart manager" allows you to stop apps from running all the time.
Do you have an n9005? If so the Snapdragon Battery Guru app definitely helps by switching your networks on and off based on usage, etc.

I never thought about that, I had that on my HTC One. But I didn't find that it helped much in all honesty. I'd be interested to know how well it's responding with the N9005 though, are you using it?

Yes I am. It doesn't make a night and day difference but it definitely makes a difference. I even uninstalled it to double check that I wasn't imagining it, now I'm annoyed with myself because it's still learning again.

Without all you wrote.. rules are those:
1) NEVER close apps (if you close the app ram pages will be deleted, so, it's needed to re-upload those, it has an huge energy consuption
2) use the phone "slowly".. i'm meaning, the fingers moves
3) if you are reading a text, read all the page than slide to see the new text, it's to prevent an high ramp up of frequency for long time
radicalisto -> thx for tip
nakedtime -> App Ops is quite good app ! Thx But "AutoStart Manager" is not working on my phone (crashing)...
dr.m0x -> I need to test this app thx
It's npt a good way to install an app to controll emergy consuption..
App needs cpu usage.. cpu ramp up..
so, you disable the radios for little time, and energy spent to do it could me more by cpu ramp up frequency
i suppouse you have the snap version.. and.. as i can see, snap has a good ondemand sysfs setting, it means it doesen't grow up frequency too fast, so, more than this is quite impossible
Only with an huge undervolt
I've installed this "Snapdragon Battery Guru"... now it's in "learning mode" I will see if it will help or not...
I have better replacement for "AutoStart Manager" and it's called "All-In-One Toolbox" which have the option to chose apps for autostart (and has many more other features) - i'am using it for quite a while and it's working fine

Snapdragon battery guru raplace the sysfs of the governor
First impressions from this Battery Guru are not so good... Battery is running down faster than without it... Maybe because its still in "learning mode"...
Yup just cause it's in learning mode, it'll settle once it's learnt everything

I will wait until "learning mode" ends and see if it's working
I am not a heavy user so a battery last more than a day sometimes 3 days.If I was I would just get an extra battery and not obsess over trying to maximise battery life.One of the advantages the Note has over most other phones is a removable battery.Take advantage of this feature.It takes less than minute to change a battery.
Replacing battery requires switch off the phone and taking off back cover of the phone (i'am affraid that it will damage it after many opens... i'ts a plastic after all...) and then put back cover and switch on the phone... It's troublesome and not comfortable...

It doesn't take long to switch the phone off.Mine takes 10 seconds.Taking the back off and replacing the battery takes another 15 seconds.Turning it back on takes another 15 seconds.All up less than a minute.
I can imagine how some people might be reluctant to take the back cover off almost daily.The back cover feels a bit flimsy and it's reasonable to assume it won't be durable with that sort of usage.I have the Note 1 and after two years of almost daily taking the back cover off it is still fine.The Note 1's battery life is horrible and even with light use I don't get a full day from it.Most people replace their phone after 2 or 3 years anyway so I don't think durability is a problem unless maybe you plan to keep it for 5 years.
But I can understand why some people might be reluctant to repeatedly tear the back cover off their brand new pride and joy.
I guessed everyone had their own way of energy conservation. For me, I use dark wallpaper. For our screen (Super Amoled), Black = LED off. LED off = not using energy. So in theory, black wallpaper or black background should uses much less energy than bright sunny light wallpaper.

This is very true for Amoled displays.The only time I notice my N3 drains the battery more than usual is when the display shows a lot of white such as internet surfing and using WhatsApp.Watching a movie does not display a lot of white and the N3 battery life becomes remarkable.
Battery
Go into the application settings and deactivate all samsung apps u dont need! Saves alot of Battery. Don't charge ur note if its Not empty. Just charge it if u are under 25%. You can also work with Tasker - it helps you to save your Power if u change yours settings automaticly. Also dont change ur brightness all the time
Hope it helps
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?

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
watch this!!

Do you think the state of the "always on " really saving battery power than normal mode ?
There is some research that ?
I suppose you are asking: is the Samsung always-on mode better than a simple application that enables some kind of always-on screen ?
My answer is: no, the Samsung's always-on display is not a special power-saving mode. It is as bad as any application that shows a screen all the time.
GSMArena battery rating for S7 Edge without always-on display is 98h, and with the always-on display is 67h. So the always-on display eats a lot of battery.
On the other hand, the LG G2 has a rating of 60h without always-on display, and 50h with always-on display, so LG has a true efficient always-on mode, while Samsung is just like a simple application.

It's not saving power as it's still pixels that the battery has to power, especially since the clock and calendar has to move around the screen to prevent burn in on the AMOLED panels. While it doesn't use a lot of power, it still draws from the overall battery life of the device. If you're away from the charger for extended periods of time then i'd suggest not having always on display enabled but if you're able to plug in int the middle of the day if your battery gets low, then it shouldn't be a problem.
Yea. I thought I was going to like the AOD but I don't. For one I can definitely see an increase in battery usage and I also hate how it moves around the display. I know it's nessesary for image burn but while I'm at work, I keep my phone in a stand and every time the clock moves around the screen it makes me glance at it. Just got annoying after a while.

It eats 3% per 9hrs for me on exynos. Pretty good if you ask me
It's really a question of how much you use your phone as a clock. If you're constantly turning it on just to check the time and turning it right off, then yes, it can save power because turning the whole screen on just to check the time will use more power. Otherwise, if you wear a watch or have another source of time handy (or just don't bother tracking time that closely) and only check the clock occasionally on your phone, then you're probably better off with it off.
Of course personal preference is also a factor, but I'm just talking about the so called "battery saving" logic behind it. It'd have more potential for saving battery if it showed you your notifications like the Moto AOD does.

you meant LG G5; and yes, they seem to have developed their AOD better; in fact I think that they prepared it for a longer time and Samsung just implemented it empirically (probably using a developer like the one that delivers NoLED)
sure, AOD notification in LG G5 is much smaller and less bright but it gets the job done nonetheless
on the other hand, Samsung should really put a timer for AOD (during night I cannot stop it, just replace it automatically with night clock which is dimmer) and adjust the brightness; they have enough sensors and algorithms in order to achieve that; one forum member suggested that I should just turn the phone with the back side up, but this way I cannot see the led notification in case of missed events during muted....
also, anyone can tell for sure whether AOD or night clock is is more energy efficient???
