I hve been using my phone on power saving mode from 2 days to save battery and to hve more life out of it. I wana ask tht it is ok to use it continuously on power saving mode forever??
Any ideas??
No problem in using power mode all the time. It's a feature Samsung enables to save battery
Yep. Can't see a problem except the expected performance downgrade etc.

Personally I hated the power saving modes in every smartphone i had cause it affects performance. I will buy a spsre battery and a charger. If you are ok with the performance in power saving mode you should use it!
Enjoy your phone to its maximal potential. Don't let the battery saving issue to disturb your user experience.

My phone doesn't decrease in performance with saving mode enabled. It is always fast.

Not the case with mine, I notice a decrease in performance. It most likely under clocks the CPU...
In regards to the original question, no there is nothing wrong with leaving the phone in power saver mode. In fact you could probably argue that its better as the phone creates less heat.
Ideally I'd like to overclock mine
Well there is no such thing as saving power without sacreficing preformance. (unless you undervolt it or use more power effectient drivers)
But you should be ok running in power save mode all the time, although I do question why you bought a top of the line smartphone then. I think you would have saved more power (and money) buying a lower end phone.
It does govern the cpu. You can uncheck it. I leave mine checked.

Truely speaking i cant see diiference of even 1% in comparison to power saving and normal mode. Any one knows y battrey depleting though good but at same rate in both modes??
juice defender app does a good job for me. i use the basic settings but you can tweak it to save more battery.
Power saving appears to cap the clock speed at 1.0 GHz rather than 1.4 GHz and it may also disable cores, too. Most of the time it feels just as responsive to use. It is less snappy for some apps and benchmarks quite a bit slower, but I feel I'm splitting hairs as it still feels quicker than my last handset.
I see two days of moderate use with Power Saving on. I don't quite see two days with it off, but the difference is probably not statistically significant and the device is still new.

im using a power saving application on Xperia S ... is it okay to keep it working all the time??
thank you ....
ButterMaker: first of all, wrong forum, also battery saving apps are known to interfere with androids way to handle memory so I would say no

Yes, should not use battery/ram optimization apps. They interfere with androids core system.
I uninstalled all these apps after trying and researching. They eat more battery then they save. I only use battery stats apps to keep a log of battery drain.
Now I easily get 40+ hours on my S3 with moderate uses.
you guys might think i'm crazy for asking this but i think there is an option is STweeks in Siyah's kernel. I'm only asking those who just use their phone for daily usage and not for heavy game playing (i am one of those). Just wondering what the experiences are and if battery life increased much. As of now the battery life is great for me, without turning any cores off.
On that note, i know there is a S3 version with 2 cores with 2gb of ram.
Personally I wouldn't expect it to make any noticeable difference, but Samsung's power management should do this anyway for normal usage, and you may find intensive tasks take longer actually adversely affecting your battery life.

i was looking for a long time to increase my touchpad battery life on android and i found that option that did it like magic so i wanted to share it with u
settings > developer options > don't keep activities
is this in the stock rom or it is cm option and is there any app makes the same function
the only disadvantage of this it is mess with multitasking but it isn't annoying .. i prefer the battery life
thanks for the tip
im gonna try this today and see how much better the battery life is.
thanks for the info

It screws up shutdown widgets because they close as soon as they're activated. The only way to shutdown or reboot the tablet is with the power button- for me at least. I deactivated it.
dude
Dont post things like this in DEV SECTION.
I dont know if some moderator is gonna close it. Idnc
But just for the info. It goes more in general section
How does this safe battery life? As far as I know this option will prevent background processes from running, so if you have something wasting CPU cycles in the background it could improve battery life. But any decent app should sit idle in the RAM using a marginal amount of power.

Seems to me that this question is irrelevent. It is so simple the try that who cares how it works? Either it extends your battery life without hurting your "user experience" or it doesn't.:laugh:

Does turning on PLANE MODE avoid battery drain?
can you give other conplete suggestions?

Sure it does. It turns off all radio, and using radio uses battery. So PLANE MODE is a great battery saver.
Also, at night you can turn off 3G, only using 2G (you will still get SMS and the phone will ring), but it uses less battery.
Turn off wifi, data and bluetooth also makes the phone use less battery.
When the phone goes into sleep-mode, it can be set up to turn off all those stuff.

Undervolting the cpu always works for me, although some people say it reduces the phones life. Setting the max. processor speed to 320 or 480 mhz also saves a lot of battery, and its more than enough for a daily usage GB ROM.
Next, the more apps you have installed, the more extra RAM gets used. Less RAM usage means a little bit of battery saving.
Some people also claim that using an odexed ROM prevents battery drains, but I'm not sure about that.

I don't think Sleep mode is that good. I noticed that when we turn On sleep mode the battery doesn't drain, but then when we turn it Off it starts to drain faster for a while.
Undervolt i don't think it saves that much battery, i think it's about the same because i'm using undervolt now and i don't feel the difference.
In Performance options, turn off that Free Up Ram thing and put low values on SD Cache and Virtual Memory ( the lower the more battery saved ).
And off course, more battery is saved by turning everything you don't need OFF like Bluetooth, WiFi, Net by DATA, 3G, Brightness ( if not at minimum yet ), Animations of the rom, etc...
About odexed roms, it's a lie man, i tried almost all roms till now and the odexed roms for me were the worst in battery life.
About CPU, only put 480mhz max if you Type 2 fast on your phone in SMS and stuff ( that's why i have 480mhz xD ), but see for yourself if 320mhz Max is good for you or if it is a little bit slow to type SMS and stuff.
Cheers

Like i said, 480mhz is (stable) enough for our phone, you don't need more than that to run any apk .

Not true, i always used 480mhz without any problem in any rom. If a rom has random reboots it's a Rom problem or an app problem.
Besides, if an app isn't meant to work on our phone it wouldn't even open, so random reboots is out of question unless the Rom has problems.

Only on phones with better hardware (e.g. a samsung galaxy s2-s4). If you set the frequency to low on that sort of phone, it will reboot. But not our phones; I once (accidentally) set my freq to 19 mhz, but it didn't reboot, I even managed to reset the clock speed without having to reboot.

19 mhz or 122 mhz. 19 mhz will mean that, while going into sleep mode, your phone will save more energy, but it might take longer to wake up.
480 or 320mhz Maximum ( your choice ), 19mhz for minimum. Honestly i don't know if 19mhz actually works :S , i feel that it drains the same battery as if it was 122mhz. And in sleep mode i feel that the battery drains faster for a while after we turn off the sleep mode :S , but it's always better to check it out for yourselves xD.
I own a nexus 10, I like it, but a big complaint by many is the battery life. Apparently a large portion of the battery drain is attributed to the screen, which makes sense due to its high resolution.
I was curious as to whether you can dumb down the screen but still have text legible and images viewable without too much loss of quality. Also if it would actually benefit battery life.
What I mean by that is turning the 2560x1600 into 1280 x 800 by turning off pixels in a checker format, every other pixel being turned off. If it looked terrible they'd be no point, if it didn't save any battery life they'd be no point.
Reason as to why you'd want to do this, is that if you were reading a simple text file you might not care about high detail, maybe some games don't work at high resolutions and maybe reasons I haven't thought of.
Is it possible? Would it save battery life? Would you still be able to read text?

Search around the forum a bit - I recall seeing a few mods that essentially turned the screen into a 1280x800 rendered screen. Until we see some stability improvements (hopefully) in 4.3, there are a few people still running it for the speed.

Thanks for pointing this out, I assume it uses 4 pixels as one, which is great for certain games and general performance I imagine. However I doubt it would improve battery life, right?

It could. Less demand on your CPU, GPU, and RAM should mean better battery life.

I don't think it would improve battery life very much, no.. I get awesome battery life when watching a movie or reading books, but when it comes to any kind of streaming (netflix in particular) my battery just drains, even more so then on my phone. I usually underclock when doing that, because it really doesn't require that much CPU. The tablet still kicks my laptop's butt in battery life, so even at 6+ hours I can't complain - and when I hit 8 or so I'm really quite pleased.

While it probably would reduce some drain, I'd imagine it would be minimal based on percentage of battery drain mostly being the screen. Perhaps under clocking and under volting would reduce some battery drain, the main way to conserve battery is reducing screen draw. That is why reducing brightness has such a big effect, I was hoping that you could turn off pixels to reduce the drain. Though I'm not sure it's possible or it would look good.
Lolwut? Battery life a major complaint? WAT? It is a 10in tab with insane hardware pushing an insane resolution that averages 7-8hrs of SOT. How is that bad? Some people's expectations need to be brought back down to Earth.

The majority of the battery life is not from the pixels....but the screen itself (i.e., the lighting).
Yes, the pixels does use up more CPU/GPU cycles, but the majority will always, and I repeat always, be the screen. Why do you think the iPhone gets such awesome battery life? They have a tiny screen.

Still, the rendering of the bigger number of pixels uses more power. Not sure about percentages though. This is specially important when running 3D games or other graphics-intensive apps. But I still credit your point about the back-light being a great deal of it.

If that's the case, the iPhone 4 and iPhone 4S should have gotten worse battery life than their Android counterparts back in the day. Did that happen? No. The energy footprint on ARM devices are so minute that the backlighting still takes the trophy in terms of energy footprint.

Apple only has a small set of fairly similar devices to support. All have the same series of GPU, similar hardware, and iOS is a less resource intensive OS. There are too many differing factors to fairly compare battery on two devices on the two OS's.
