hi all,
I recently switched from stock rom with root, to pure nexus rom and ElementalX kernel.
the reason i changed the stock rom is because of battery drain while phone is asleep.
the wakelock detector showed that the play store and google services kept it awake.
now the awake percentage is much better, but it seem like the battery runs out faster when i'm using the phone.
the battery can loose 1% an hour asleep, but it seem like every time a touch the phone it looses its power really fast.
does it make any sense?
should i just admit that the 5x battery just isn't enough for me?
i'll be happy to hear you advice,
thanks
I agree phone does drain fast whilst using the phone I can't get a full day of use with this compared to the iPhone 6 I had

Maybe you guys need to look at some of the apps you run? Facebook and messenger are known to cause these issues, there are alternatives but it may be worth a try.
I have no issues with my phones battery and last a day no problems.
I can use my phone all day at like 85% brightness and then not charge it overnight, wake up the next day and still have enough battery. Usage differences aside, the things you should be looking at are the kinds of apps you're using and the way you have your kernel configured. As suggested previously, apps like Facebook and Facebook Messenger are widely known battery killers (Metal is a good alternative). Make sure you have adaptive brightness on, the screen is, by far, the biggest battery drain. Lastly, but more importantly, configuring your kernel and cpu governor would really help. I know you said you're running the ElementalX kernel, which is a fantastic kernel. I'd recommend getting the ElementalX Kernel Manager app from the play store and using that to tweak the kernel to your liking. Specifically disabling Touchboost and trying some of the tweaks in this thread. Touchboost is a battery killer as well and rarely effects the fluidity of the phone. The tweaks / profiles in the post I linked are an easy way to apply different values to the tuneable parts of a CPU governor. These values effect things like what frequency the CPU is at under a particular load, the input boost frequency (the frequency the CPU jumps to when you interact with the screen), and generally how the CPU behaves. In most cases, users have reported a nice bump in battery life AND performance. Some people are reported achieving over 6 hours of Screen On Time on a single charge. If that doesn't get you through the day, then idk what will.
The battery in the N5X isn't huge, but it isn't tiny by any means. It really depends how you use your phone; everyone's different. I highly recommend doing what I said above, it'll make a huge difference in your device, I promise.

Would highly recommend AT LEAST getting a different kernel and following the same recommendations I made above. A different ROM that's optimized with UberTC helps with overall responsiveness and battery life slightly as well.
Hi thanks for the advice much appreciated I don't run apps like Facebook and Twitter not a fan however I will try a custom kernel and see if that makes any difference
Thanks again

thanks,
i an using messenger and Facebook, but i blocked their active wakelocks.. it think it does the trick. this is the problem with those apps, right?
when i'm not using the phone the battery consumption is OK, my problem is with the time i'm using the phone, so i think tweaking with the kernel setting may be useful... i'm trying to use free apps only, but i may consider downloading the ElementalX app if it turns out useful.
Regarding the screen - is auto brightness is a battery saver?
thanks for the help

The EXKM app has a number of good CPU governor profiles Built in.
I think it's really worth the couple of bucks.
Also if you're indoors mostly you can probably keep the brightness at 10-20% instead of auto which really helps with battery life.
I bought the elemental app last night and installed the elemental kernel before my phone used to say 8 hrs of battery remaining after installing the kernel it now says 2 days remaining what a difference I've kept auto brightness on disabled touchboost and I'm using the butterfly profile
Thanks for all the advice people
Sent from my Nexus 5X using Tapatalk
bought it too
so,
when you say use butterfly,
you mean you enter to cpu->governor options,
you load the profile for both large and big cluster,
and makes it "apply on boot"
thank you all again

Hi guys!
This One X is very performing smartphone, games are really pretty... But I can stand that battery problem! I've tried so many rom, using setcpu for ondemand governor of the Tegra3... But I still not have so many battery life!
Can you guys suggest how rom, kernel or something else can save my battery?
Generic suggestions about this problem... Now I'm using Jdroid exodized 3.0.3 with bricked kernel v0.2, but battery is so draining... 63 % of battery with 1.37 hours of screen.. 4 h 22 min on it! =(
Hi!
I see a lot of people complaining about battery life, but if you take a look around you'll find the thread where people posted their battery usage. Me - I'm using rooted OneX running the stock ROM and am more than satisfied as far as battery life goes. I do 15 hours with ease. If I try to save it it usually lasts for more than 24 hours. Maybe you could try stock rom + root ... maybe a little underclock? I've been hearing underclock is quite the juice saver.
Hi,
I am the same I have tried custom Rom's but they claim to improve battery life but they just move the tegra 3 powersaving driver into the correct place!
I have a unlocked O2 HTC One X with O2 Rom and flashed battery fix and rooted the device!
Using this thread: http://forum.xda-developers.com/showthread.php?t=1597227
I have managed to setup a shortcut using widgets on the screen to select how many cores I want to use. I find that using one core clocked at 1.5GHz is fast enough and I don't have much lag! This has helped my battery massively! This is because O2 still haven't pushed through the HTC updates yet!
And also using this thread: http://forum.xda-developers.com/showthread.php?t=1630200
I flashed this using CMW and this has also helped.
I also find disabling some stock apps using App Managment in Settings, also using CPU spy from the Play Store and Battery Usage in settings. I can find the apps that use the most CPU power then uninstall or limit their usage (maybe using the internet instead of a dedicated app) this then has the phone stay in Deep Sleep for longer. I can easily get through 24hrs without having to try to save battery at all! I sometimes have almost got two days without charging!
Another tip is in the Usage app you can Restrict Background data over the network although when you connect to your WiFi it enables it again. Although it is meant to help save your Data it can also help your Battery Life.
Hope this helps!
Steven
Thanks for the answer!
I noticed that, in this Rom that I'm trying, I've the Screen that consume a lot of battery, even in the lowest brightness mode. Not using WiFi, 3g data, autosync, nothing, only a lot of text message received and sent. I think that this S-LCD2 consume a lot of battery or maybe the software of HTC, this time, is a loot poor of balance with this expensive hardware.
Do you think I can improve battery life with the tips that you said? I'm using this ROM right now http://forum.xda-developers.com/showthread.php?t=1597778.
Setting CPU to ondemand governor 304 mhz min and 1.5 ghz doesn't help me? I must disable some cores? I can give it a try, hope that this tips can be made in this AOSP Senseless Rom.

I'm asking myself [ and you ] if this screen consume really a lot amount of battery... Or there is some problem with my one x... Reaching the 3+ hours screen on is a good result, but in a 15 h battery day life, I hope... Maybe I can reach disabling a couple of processors
Don't worry about the screen, it will always take a lot of power whatever you do! It isn't worth messing with it.
You don't need to mess with the CPU although personally it does make a diffrence to the battery, I don't notice it too unless I am gaming!
Maybe an app is preventing your phone from going to deep sleep whilst the screen is off
Try using this app: https://play.google.com/store/apps/details?id=com.bvalosek.cpuspy&hl=en
If it says that your phone hasn't been in deep sleep, We need to try and find the culprit. Once you have done this maybe post back and I might be able to help you sort this out! It took me a while as I had this problem but it was definatly worth the effort!
Try looking in battery in the settings and see if there are any apps that are using a lot of power (maybe take a screen shot) and also try in Data Usage, there maybe apps using the Internet whilst you aren't using the phone. This also wastes the battery. If you restrict background usage (only on certain apps) it will only use the Internet in the background whilst you are connected to wifi only. Facebook is a good example!
Hope this helps
Steven
If you don't understand anything please say, I know my explanations are awful but I will try my best! I think I have changed everything here to fit your rom!
The rom itself although you or the developer know this but the overall system could be causing a problem! (just a theory!)

You're too fine with me steven, thanks!
I've downloaded Cpu Spy and it says that my one x has been in deep sleep for 70 % of time, so there is no problem with some apps doing something during screen off. My problem is that when I'm using all 4 cores, without internet via wifi or 3g, without autosync, nothing at all, and screen at lowest brightness, there is still a drastic battery drain while I'm using only Message app a lot. I don't wanna think that my HOX have a fault battery, but how can I test and prove it ? I don't know if there is a program, app or test for doing this thing.
Now I'm with that ROM Senseless AOSP ICS, I will try next charge with two cores actives only and view how much I can stay with that SetCpu settings. I'm using this settings: 101% Battery <, CPU Max 1Ghz to 51Mhz and priority 100, governor ondemand ; screen off, CPU Max 1Ghz to 200 mhz and priority 100, governor ondemand. I'll give you the result soon.
you need to give it time to settle the battery mate. i manage to go a day or two and have like 3 hours screen on time and that is with everything on. if you need any help send me a PM mate and i see what i can do to help you. and i would not use SetCpu for now i am using No-Frills. And switch from ondemand to Interactive. and that is with 1.5Ghz as max and 100mhz mininum

I agree that you should not use set CPU although you are best using ondemand as that is only using the amount of power you need, interactive keeps the speed high to increase the overall speed. (not good for battery life) also maybe, my mothers Samsung Galaxy S2 had battery problems and she got 6hrs of battery out of her phone at max, she always carried her charger around.
I calibrated the battery without using any software, I just fully charged the device and left video/audio/maps on to get rid of the battery as fast as I could and then fully charged the device. All I am trying to say is give this a shot (I did this when I first got my phone) she now gets on average 2days battery life! I know that it can take ages but it is defiantly worth the effort!
Hope this helps
Steven
Also, how do you find that ROM it looks great. I think I might try it!

VillainROM v2 + Franco Kernel.
Sent from my HTC One X using XDA
I've used cm9 and aokp the past month and tried the stock Kernels that come with it and Franco's. One thing is for certain. No matter combination I get horrible battery life. If I run stock android with my extended battery including various Widgets I get 24 hours battery life pretty easily. Moderate usage and some heavy usage. With cm9 I'm getting maybe 15-16 hrs with aokp maybe 8-9 hers and I'm using Franco's kernel right now. I don't understand this. People talk about how much better the battery life is with various ROMS than stock but I'm not getting it. I'm getting like half the battery life I was before. Any ideas?
Sent from my Galaxy Nexus using Tapatalk 2
I can relate to you. Was in CM9 and Franko's kernel and as you said, horrible battery life. I went back to stock but this time I did not install apps thar would require services running (well I have to run WhatsApp so that's the only one running besides default abdroid services).
I am seeing better battery life this way.
The next step would be to install CM9 and restore all my apps to see if I can replicate the same battery life.

you need to find out what apps are keeping your phone from sleeping dude its not the ROM or Kernel if you want to find out you can use better battery stats or just read the permissions on your apps otherwise its probably cause your on your phone too much with the screen on first show use a usage screen shot then how many apps you have we can narrow it down

I swear my battery life is better with the kernel that comes with AOKP rather than franco, which was a bummer since I'd just bought the franco updater app, perhaps just my imagination or maybe something just needs to be tweaked
Well, this has pretty much nothing to do with the ROMs/kernels, you flash to the device. If you use the device for heavy gaming, you use loads of apps etc. the battery life will obviously be bad, because the CPU needs the according CPU clock speed...
Underclock the CPU, or better: Get AnTuTu CPU Master pro, and set the profiles, underclock screen off, to 700 MHz, and every other proile, where you do not neccessarily need the device to that speed, not below, otherwise it will just crash... That way you have the best battery life, for your usage, so basically, every time you switch the device's screen off, it will save a hell of a load of battery
Under clocking doesn't do much for battery life contrary to popular belief. It just increases the time it takes to process a task. It might take 1s at 1.2ghz vs 1.8s at 800ghz to complete a given task for example. So yes the cpu will run at lower speed and voltage but it still also take longer to return to idle.

Well, I don't really mean to break this, because it is right, but not completely...
Underclocking & undervolting, when the device is not in use (Screen off) saves loads of battery...
And because it's a dual-core, it takes mostly just as long to open an app at 700 MHz, as when you're doing it at stock clock speed, or voltage or higher.. So, in that case...

Not sure how this wouldn't have to do with the different ROMS and kernels since I stated what battery life I was getting with stock vs using a custom kernel and ROMS. I'm giving a comparison of my battery on each with the same usasge and they are different.

You could use InteractiveX or Hotplug as CPU governor, they switch cores off when the screen is off
Though from what I saw, and what I read from other users is that switching cores off doesn't save that much on battery... the CPU isn't the biggest battery consumer. If you want to save battery you should dim your screen, it's the biggest battery killer

Battery depends on how you use it. Usually some custom ROMs can help save battery life but it has been proven by a lot of people that Touchwiz has the best battery life, but really there is a small difference since the phone averages 4 hours of screen time. :silly:

Dude, if you want to just increase battery life with Jedi, I'd say find Cl3kener's last 4.1.2 Tiberius Kernel and flash that. Install TricksterMod from the play store. From Trickster change your scheduler to bfq and your governor to Ondemand. Turn minimum CPU frequency down to 192. I also turn down my GPU max frequency down to 177, and my mpdecision idle_freq to 192. You should definitely some increase in your idle battery consumption. Unfortunately there's not much to do with active battery consumption like games and video .
I used that rom for 6 months...(I stopped using it, because I started to hate touchwiz), and I didn't have any problem. It's probably going to work for you too, but just in case, take a backup. (Remember that you have to install a custom recovery)

You can under-clock your kernel... Even a little bit should give decent gains in battery life, maybe. Let us know if you do, how much better it is!

You had to say that I'll have a battery saving kernel for the gpe with a tweaked governer setup in a day or two to try out. The goal being to not lose power, right? Well, we'll see!
Shortly after, If I get it right, Bob will probably put it in the v500 if there are no conflicts. I'm going for 20-25% savings. Eh.
Typically my screen will consume about 93% of the battery.
Will a rom or kernel be able to save 20~25% on the screen consumption, or only 20~25% of the remaining 7% ?

Thanks!

FINALLY! i've tryed all apps without luck, also tryed some custom roms without luck,
partially good results with madhi rom + dyn.kernel + trickster mod
this qualcomm mpdecision sucks!
please... a kernel for v500 for underclocking CPU + GPU!!! THANKS!

I dunno if this option is in any other rom, cause I've been using CM for the past 2 years on my devices. Theres a button called "Perfomance" in Settings. You can underclock yourself there.

Check your underclock with perfmon... only 1st core underclock!

Just an update. Go here for an init.d script for battery life. Init.d scripts
caveat: must have init.d support, which means custom kernel and root.

Cool! The changes are slight, but should be very effective. I didn't want to lose any power.
Let me know how it works!
Okay, here's the scoop.
I have used 5 hours of screen on time with 43% of my battery left!
This was a mixture of Facebook, kindle, and dolphin. The screen is using 90%, at about 55% brightness average.
Given these variables, I figure to get at least 7.5 hours out of a charge.
Here's the even better news. The 88sleektweaks has made my tablet response BETTER than without, and can easily tweak this toward more battery in the future. Without a doubt.
I can see getting 9 hours out of this with no feeling of slowing down before I am through. Yeah, that good!
I have to stop where I am now though in order to test another kernel.
Anyway, that is a two hour improvement over what I was getting,... With better/faster response from my tablet.
Is it not required to go through a few charging cycles before battery stats start being accurate?

Not bad, 7 hours screen on time with 10% left on battery. Mostly Facebook and Dolphin browser. Also keep tablet talk on all the time, and make sure all my notifications are active.
Anybody else having good results using the script?

I can't say yet as I encountered issues with android system and android os using up battery. As I installed your tweaks as well as starting using greenify at the same time I made the (wrong I think now) choice of removing your tweaks.
But it now looks like greenify (or at least my going nuts and hibernating every thing ) is the problem.
So for now I've reset greenify and will monitor it overnight.
Once I'm happy with that I'll reintroduce your script
All the best rich

Hi, I have a question:
does KnockOn feature consume extra battery?

I doubt it uses much if anything. Sometimes when I haven't used the tablet all I have to knock 4 times instead of 2. LG's stock roms are better than samsung's stock roms. You could always try one of the aosp roms as a test comparison. My tablet was idle with LG's stock rom and bob's kernel for 1 day and 14 hours and I only lost 5% battery life no radios (bt/wifi/gps) were left on.

I loss 5% per night so more or less 10 hours...I think it's too much
furthermore knockon doesn't work very well
How enable init.d in stock 4.4.2 ?

You would need to build a kernel for stock 4.4.2 that has init.d support. You would start with the LG kernel source, get the source to build and then try to incorporate Sleekmason's changes that he has done for the GPE device into the V500 kernel. This would involve carefully looking at his tweaks and applying what is needed for the governor and init.d support into the stock kernel. Once you have built a kernel like this and it is ready to install. Then you need to root your device and you would need to install a custom recovery so you can flash the new kernel. The installation instructions would be different from what Sleekmason does since the GPE device has an unlocked boot loader.
When I was trying to do a custom kernel on 4.2.2 I found that my resulting kernel from LG source didn't match the installed kernel on my device. This bothered me and I wanted to make sure I understood the differences before proceeding. This combined with real life getting in the way (my wife is expecting) caused me to shelve the project.
I believe I finally figured out what I was doing wrong. However I'm now running 4.4.2 so my efforts are not useful to me other than to help me if I decided to attempt a 4.4.2 kernel.
