is it true that turning off animations will increase battery life? i know that if you set it to 0.5 your phone will feel faster.

i doubt it.
I'm going to hazard a theory here, but I'm sure any battery life savings, if there are any, would be so negligible that they are practically unnoticeable. I like the 0.5 setting because the phone feels and acts more responsive but gives a smoothness to the opening and closing so as not to be jarring on the senses.

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:

What has been people's experience with battery life with the different ROMs? I've been on AOKP for awhile, and the battery, quite frankly, sucked compared to stock. I'm currently on PA and am getting just under stock. For me, battery life is first priority, even if there is occasional stutter. Testing battery life takes a long time, so I just wanted to see what others have been seeing. I would stay on stock, but I really want Tablet UI and real setting toggles.

Disable Google Now and see if that helps, totally did on my HOX and I've yet done it to my Nexus but I've not used it enough to actually deplete a battery yet.

You sort of want your cake and eat it too. If you want a ROM full of features and packed full of unicorn blood and the tears of leprechauns something is going to have to give and that will always be the battery life.
I use pa ...I charge my tablet every other day
Sent from my Nexus 10 using XDA Premium HD app
Stock ROM
Ktoonsez Kernel: Underclock to 1.3Ghz
Disabled: Google Now, GPS,
Freeze: all stock apps I don't use, Magazine, books, currents
Battery Life: 4 days.
I read a lot.
Don't game.
Watch videos with zero stutter.
I finally charged my tablet last night. Im at 82% in 8 hours.

I'm addicted to my tablet... I've been using it without stop for the last three hours. This are my results with Paranoidandroid:
Very similar with stock though. I think I could upload some as well.
I'm pretty sure this is stock. Not a lot of difference as I said. Both of the images are with very heavy usage, I mean, screen on all the time, but almost the lowest brightness. With the screen off I get almost no drop.
(I couldn't attach the image in the previous post)
Battery life will always be a combination of idle drain + screen on drain. THe most important is obviously how long you can actually use the tablet (screen on time), but you also need good enough idle drain to not lose hardly any charge between when you use your tablet.
The more features you add the less battery life usually is. So either keep PA so you have the tablet UI or use a ROM that is very close to stock, like the stock ROM from scrosler or Muzzy's ROM.
A kernel can also have greater effect on battery life. If you want the best battery then go with KTManta kernel. Use either PegasusQ or ktoonservative governor and add in some undervolting to lower power draw. Using this combination I was able to get over 13 hours of screen on time in 1 charge. Idle drain was about 1% every 8-9 hours.
Personally, I've found that my battery life has improved maybe 10% since running cyanogenmod. If I'm really lucky I can get 7 hours SOT. Not a huge improvement over stock, but its definitely better.
Its worth noting that I use the "performance" CPU governor, which is supposed to be a battery killer. Strangely it doesn't seem to make much difference for me though, it just makes everything quicker!

Well, it is difficult to notice a higher battery drop when it is already insane... XD. Well, according to battery widget I'm getting around 8h with the screen on, which is not bad.

I've used the "battery widget" for a very long time and that app is a battery drainer. Got way better battery life uninstalling that app.
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.
So ive noticed a marginal increase of battery life on my shield tablet by switching the power mode to 30 FPS and I was wondering if there was a way to change the G3's display refresh also? I just like experimienting with stupid settings like that. I dont use my G3 for games, mainly GPS and youtube, so refresh isnt that big of a deal to me. I would just like to find more ways to squeeze battery life and performance, as if my ZeroLemon isnt enough...haha.
Any help/Ideas would be AWESOME! Btw, running Eclipse!

Very good indeed save allot of battery life without any noticeable loss in performance and no reduction in screen's refresh rate
Many people praise this light mode but I don't really get it, if it's so much better and literally same performance as the standard mode; what would be the reason or higher performance of the standard mode? Doesn't make sense at all.

It's not the same performance. The peak clock of the X3 core is reduced in this mode. The thing is, it's not going to be noticeable in the day to day because the SoC is so beastly anyway. If you're doing heavier duty tasks like gaming or video encoding, you're more likely to notice.
ETA: I just found out that Light performance mode is disabled when Samsung's gaming tool detects a game so there would actually be no negative effect on gaming when using Light mode. Really there probably isn't going to be much of an impact other than on benchmarks that's noticeable to anyone as performance stability should be improved as well providing a smoother overall experience.
