Just got my note I was wondering if people could share their tips on how to get great battery life on the note!
any tips (even the most basic) will help all us first time Android users
So share your tips, apps, settings, etc!

If you want to save max battery. Turn off 3G and only use 2G. Then lower brightness. Reduce frequency of app updates.
Those are the best tips. I keep brightness on auto. And I keep updates to once an hour for most things. It give me a solid day.

Thanks!
I downloaded setCPU and have it so that the processor goes down to 800mhz when the screen is off.
I am not sure if that is helping or not though.. still struggling with battery life.
Get JuiceDefender Ultimate. It helps to automatically turn off your Data Network and your wifi whenever your not using your phone, it reopens them periodically to check for any updates on ur apps. Smart app and it has saved me x2.3 of my battery life.
thanks!
Do you think juice defender ultimate is better than setCPU?
Disable fast dormancy. *#9900# and the select disable fast dormancy and then save.

Here are some tips for prelonging battery life:
1 - Don't use 100% screen brightness at all times - 50-60% is enough, only increase it when you need to then lower it again.
2 - If your planning to use the phone for long periods, 30 minutes or more constant use then once again use 25% or so brightness
3 - When browsing/surfing the net use the lowest possible brightness as this is the biggest battery killer. Unfortunately our AMOLED screens suck a lot of juice when displaying white...
4 - Try to keep most, if not all applications to manual updates only. Otherwise decrease the update frequency.
5 - Use an alternative launcher. I find for example using LauncherPro uses less resources/cpu/ram than the default touchwizz launcher. Therefore using less ram/cpu saves battery!
6 - If your gonna game for hours then I suggest 0% brightness!
7 - Last but least watch your apps. Some apps are poorly optimized/coded and can take up a lot of ram and cpu which then eats away at your battery!
In my case, disabling fast dormancy helps save some battery. Tough not to a big extent.
Use Screen Adjuster or Voodoo display filter to further lower screen brightness.
Install and use app that has a night mode. Eg, config opera mobile to use a user css to render white text on black background.
Hey,
Before you should know that android collects statistics on your battery in order to "learn" its behavior so within the first days of use you will see a constant improvement if you battery performance.
there are also a few apps that runs in background and has the annoying habit to drain your battery:
wifi sharing
wi-fi sharing manager
social hub
try to disable those apps using gemini app manager or titanium backup.
Thanks for the great tips. My battery lasted almost 19 hours ever since I did everything everyone has mentioned!

When screen is off, the cpu frequency is reduced anyway. Thats the advantage of sleep.

YouTube is in no way a reliable source of information when it comes to technology. Unfortunately, neither are these forums, as witnessed by the masses of people that consistently state underclocking saves battery. I've posted about this several times before, and it seems no one ever listens or trusts me, so I'll try to lay it out as simple as I can. This effect is very well known by old school Linux nerds that would push their notebooks to get longer battery lives. Intel calls this effect HUGI -- Hurry Up and Get Idle. It essentially states that the faster a CPU runs, the more energy it consumes, but it *also* finishes it's work faster. Finishing work faster is important as it means that the CPU can go back to it's "Idle" state faster. The idle (or sleep) state uses virtually zero energy. Let me see if I can pull up the voltage table for a phone... here, found this for the Sprint Nexus S 4G and it looks to be accurate based off my memory of the CPU.
1000mhz - 1.25v
800mhz - 1.20v
400mhz - 1.05v
200mhz - 0.95v
100mhz - 0.95v
Now, let's say we have a task that takes 10 seconds to complete at 1000 MHz. 10 seconds times 1.25v is 12.5v (I know, I know, voltage doesn't work this way -- but it's a good enough approximation to demonstrate this effect (and it's to scale!) and I'm too tired to explain volt vs amp vs watt, it's 5am here). At 100 MHz, though, the *same exact task* would take 100 seconds! 100 seconds times 0.95v is, wow, 95v! By capping your CPU to 100 MHz (10% of max), you are effectively using (95/12.5=) 660% more energy to do the same task.
Now, there are scenarios where underclocking can help you, such as when your phones CPU is running at 100% 24/7 because of ****ty applications or leaked wakelocks. Although underclocking does appear to somewhat fix this, it's a complete ****ing hack and won't give you anywhere near the amount of battery life that you'd get by uninstalling the ****ty app and letting your phone go to sleep.
Make sense?

That's great, a very efficient way to save battery...
So it's basically like a modern pc running a core i5/i7 that runs at 2.5GHz when idle or when no power is needed. However when power is needed the intel Turbo boost kicks in & increases clock speed to 4.2GHz or even higher depending on what the user set it to.
In my case my PC cpu idles at 3.4GHz & when gaming or video editing it boosts to 4.7GHZ which I've manually set it to.
I don't know if people are BSing on here and in the gaming thread about how their N4's do not throttle when playing graphic intensive games or if my device is defective but..
My Nexus 4 DEFINITELY throttles down to a point where games are almost unplayable.
My favorite game at the moment, Need for Speed Most Wanted.
This game is pretty graphic intensive for a mobile device I would say. Upon first start up when the device is generally cool, frame rates are good and smooth for the most part. NFS Most Wanted frame rates seem to be about 25-30fps.
After about 4 or 5 racing events, which I would say is about 20 minutes or so of playing the back of the Nexus 4 gets warm (not hot) just warm to the touch and frame rates takes a nose dive. I would say it would be in the 10-15fps range.
I have tried it with my completely stock device, then rooted with Franco's kernel, Faux's Kernel, Matr1x Kernel, tried different GPU frequencies, OC'd all the way up to 487MHz with Faux's Kernel and it makes no difference between stock and oc'd. It ALL THROTTLES after about 20 minutes of playing.
Other than gaming, the device is blistering fast in all other areas, I have not found any hiccup at all in any UI interaction. I think Google designed to phone to handle general use with aplomb, it's truely one of the smoothest Android if not THE smoothest I have experience.
Unfortunately once this thing heats up only a little bit, gaming performance for me takes a big hit.
Try the new "bricked" kernel .. He changed the thermald file ... Should stop throttling .
don't take notice of the name Lol

Will give it shot, thank you sir.:good:
OP keep us updated please
bricked kernel... set all cores to @ 1Ghz by forceing all cores on in boot settings with the app 'system tuner'... also set governor to performance
this should keep the game running nice without over heating.
Yeah, I definitely notice the same when playing graphic intensive games. The GPU just clocks down itself to 200MHz when playing games.
EDIT: I just read your experience with the Bricked kernel. I am glad you got it fixed. By the way, did you try playing games with the kernel?

i m on v10D, i just rooted and intalled setcpu, 1500 max 1400 min gov: performance, now just after i restart/turn on my device, the frequency is right..but then after a couple of minutes it drops to 1000 mhz..i have 2 questions:1.is there a way to fix this,2.does any other version( other than v10D )offer better gaming experience...and if so, which is the best?
Thanks for your time :good:
Well i have mine when I game set to 1500 low and high plus performance. It never drops and other then that. One issue I did encounter is that as long u have profiles set up and checked it will still use them regardless if u set it in the front page to a certain speed. So u need to uncheck all profiles and also uncheck the use profiles. Basically uncheck it all then even if u uncheck use profile it still will use the profile if u select one. Here a picture from what I mean. See how I unchecked everything. U need to do this to or it still will the profiles even if not checked the use profile box.

that 's 3 people with the same problem...and no one is helping -.-, ^^^and he 's on v10H so its not fixed by update .-.
anyone??
It didn't change anything for me to put the CPU @ 1,5GHz constantly. I did a test with the game Horn and its lagging exactly as with the default CPU governor enabled.
If you think about it for a moment, it makes sense, as the GPU is doing the majority of work.
Tegra 3 CPU Clocks
Based on what I understand about Tegra 3 from this thread- http://forum.xda-developers.com/showthread.php?t=1664391, the CPU has 3 different "modes". 1.5Ghz single core, 1.4Ghz dual and triple core, and 1.2Ghz quad core (At a certain temperature, remains on 1.4Ghz or 1.3Ghz until that temperature is reached... quickly). The reason why the frequencies go down is because when the phone is utilising more cores, the frequency drops too. The move from 1.5Ghz to 1.4Ghz causes lag in games at times, which is why the maximum should be set to 1.4Ghz to prevent this from occuring. Also they said that the performance governor causes 2 of the 4 cores to no longer be in use, which is NOT good for Tegra games such as ShadowGun as all 4 cores cannot be used, so they advised people only to use it for Non-Tegra games as they do not use all the cores. Hoped I helped in any way, even though I'm a new guy. I'm not sure if this applies for ALL Tegra 3 devices or just the HTC One X, but it still looks like useful information.

Thanks for your reply..but for me, the frequency doesnt drop to any of the values above, it automatically drops to1000 and mostly its on 1 core
Which brings me to another problem...i need a way to force the activation of the 4 cores simultaneously...in most games the cpu is stuck at 100% single or dual core

Most games are not optimised to use 4 cores, so I guess using only 1 or 2 cores should be normal. What governor are you using for games, because this might have an effect on the performance.

I tried all governors..performance isnt the best, idk why..userspace seems to work fine, but still when i set min and max freq above 1000mhz, it automatically drops to 1000mhz ._. and that isnt quite good for gaming, and since i bought this device over s3 for gaming, i feel f*cked
so would an update to v10F or a hard reset fix anything??
EDIT: and there 's 4 other people with the same problem and one of them has v10F so hardware problem??if so, im hanging myself
Which one is better in real world gaming/calling/battery life/3g brwsing/gpu/cpu performance customs roms, more easy to overclock best quality phone?
Atrix HD's battery is crap. As far as gaming, some non-tegra games might run better on the Atrix because of the optimization with Adreno GPU's. Take for example MC4. It has hiccups when i play it on my O4X, but it is buttery silky smooth on my Nexus 4. There are no custom roms available for the O4X because of a locked bootloader...therefore no way to overclock yet. Unless you're a kernel dev that could help in that category.
If you're looking to buy a phone and you development is a big deal for you, then go with the Atrix HD. If you don't care about development and just want a solid phone that you can count on, then the O4X is a wiser choice. I honestly don't feel like i have the need for overclocking or custom roms. Just like my Nexus 4. There are tons of custom roms and mods available for it, but i prefer to run it bone stock but with a custom kernel.

How`s battery life on O4X? and cpu performace tegra 3 vs "krait" S4?and for updating android which one has more support for updates?, what you mean with solid? and what happens if in the future O4X doesnt support new Android systems? bcuz it has locked bootloader so I cant install new custom roms?
Battery life on the O4X is decent. I get a whole day's worth with medium use. As far as Tegra 3 vs Q Krait S4 im sure there are plenty of video comparisons on youtube you can check out. As far as updates are concerned, since Motorola has been bought by Google you can count on the Atrix HD to receive its updates faster than the O4X. And because the O4X has a locked bootloader, there will be no custom roms to fulfill your flashaholic needs. That is until we get some devs who are willing to work on the phone. But until that time comes, if you're a flashaholic...go for the Atrix HD.
When i said a solid phone, i meant that the phone doesn't have any bugs or anything...so you can always count on it on being available for you to use.
someone else with some more useful info?

what about gamming and battery life?
Battery life: i tested, and my phone will easily standby 500+ hours(in airplane mode, with 3g activated, no data: it failed after the half. About 250-280 hrs.) When constantly gaming Dead Space (only game i tested the actual time on) it lasted 2 hrs 07 minutes on full performance mode. Again with no lag whatsoever(dead space wont lag on a optimus 2x or ever weaker phones though)
I did test on a older version of Counter Strike aswell(i found it the apk on my pc. Cant remember where i got it from) - and it did start lagging when i took it on a match with me and 15 AI`s (that is, 15 guys controlled by the phone) there my battery lasted 3+ something hours (from 100%) before i got the 5% warning.
Sent from my sexy and powerful LG-P880 using xda-developers app
Could probably point out that while the battery life while gaming is a bit short - when I've tested it, it's been on average a full hour better than the competing quad-core phones when running the same game side by side.. not completely sure why that happens when comparing it to other tegra 3 phones, though.. Assuming it has something to do with the scheduler policy, along with the slightly larger battery, or something of that sort. Aside from that.. a snapdragon setup uses more power on average, and idles on a massively higher power-draw. Always been a problem with those soc designs - that the antennas and modules need to be powered on completely when there's power on the phone at all. Btw - really did manage to have the 4x run 11 days while online on the gsm network once. Didn't use the phone much - but it really is easy to get the phone to last three-four days if you don't run anything heavy. And by heavy, I don't mean just editing photos, or having the screen lit up, or something like that. I mean something that constantly runs on full processor load.
Power-draw while just playing back music and movies as well is top class. You don't read that in the reviews for some inexplicable reason.... having to do with Engadget being in love with Apple, to the point where they hate on anything that threatens to dethrone their precious princess or something. But it's still the case. This tegra 3 chip with an ips screen/gorilla glass, slim chassis w/replaceable battery/memory card slot - is a very neat design.
What? The power draw when playing music is the only thing that let me down when using this phone! Even my old xperia x8 could do better!

Could put it this way - if you want support for lossless formats, dynamic bitrate, ogg, that sort of thing - then this is the most effective system by far. Since you have power management that is transparent to the OS, and so on, so you can use existing media-players with support for the arm set and get good performance on low clocks/only the companion core, etc.

Tested; none of the (free) media players on google play could be run on the companion core. They seem to always run on the 3rd(core2) 1.5ghz core. Putting the freq at a stable 1.1ghz when screen off. And pumping to the full 1.5 when the screen is on...
Not very power saving...

Hm.. The ones using the arm 7 vfp packs should avoid that. Bsplayer does, at least.. The internal player as well. Same codec pack. The Spotify app actually avoids running on the other cores as well. That instruction set class is not unique for tegra3 either, so it should be fairly commonly used by now.

mAh reflects the storage capacity. Getting the double amount of mAh will basically double your battery life
The only other than the stock battery known to me, must be the mugen powers battery extender-something like that. And that will make your phone look like a brick.

I did some checking in the .sh files, inside the /system/etc folder, and found inside the set_governor.sh that the Z1 is pre-configured to keeping all 4 CPU cores online at the same time. For performance reasons it seems..
Should I delete every line that is related to total amount of online / active cores so the kernel can decide and take care about that by itself or should I echo 0 the amount of cores that I want to be in sleep / idle mode?
I am tweaking my brand new Z1 for even more battery life, that's why I am asking this question!

All four cores are not online at the same time all the time. At idle, only 1 core is active at min frequency 300 mhz, the other cores come online when there is demand for them. Disabling cores has never helped improve battery life in my experience, merely causing slow downs and resulting in the CPU taking longer to complete processing, using up precious power before it's able to return to min frequency.

This have nothing to do with get a slow device. This probably will help avoid battery drain and without a few test no body can said it will not work.

What battery drain are you referring to? When people talk about battery drain they usually mean when screen is of and they usually got some crap running in the background. I can get 2-3 days of moderate usage running dooms kernel and that's not bad.

Any core need energy, trying to switch them off when not needed can only improve battery standby. This is not the solution for the battery, this is one of many. We know that the crap running in background it's another reason and the screen too. Here we considering only the CPU.

Agreed, but it would surprise me if the phone runs at 4x300mhz when the screen is of. 1 core is enough and i've seen several posts saying that it runs with 1 when the screen is of. If it runs at 4 however,yeah you could save some juice by disabling cores.
