Recommend A Rom? Need To Save Battery

Hi,
I just got my HTC One X and I love it. The only downside to it so far is after leaving it on charge overnight im lucky if I get 5-6hrs out of it.
Im on the default OS and ive only installed some apps but im pretty much in the dark where to start.
Can anyone recommend the best rom to use or even just good apps or ways to make my battery life extend?
Thanks and again sorry if this is a noob question.

Have you updated your device with all the official updates? Have you disabled fast-boot, auto-brightness, satellite-GPS and all other wireless options that you don't need and opted for a 30-40% luminance rating (screen remains legible) in Settings? The operating time you get, as stated of 5-6 hrs seems pretty low. I get at least double that with intensive usage, and I mean it, THD Games! Keep in mind however that the screen of HTC ONE X, REALLY, IS the most power-demanding component of our smartphone and there isn't much that can be done about it.
As to your question, Villain rom is considered by many to be battery-friendly although pretty basic. In addition and if you have a rooted/unlocked device (I still haven't rooted mine because I'm perfectly satisfied with it for now), you can also give a try to the SetCore app that can be found i the Apps section of the HOX forum and as its name implied it allows you to control and deactivate cores at will. Also try out the well-known SetCPU app to underclock the processor and get more life from it.
Although, if you've purchased your phone recently, you may simply have to charge some more to condition the battery and then it will get to normal levels, of ~12-15hrs of serious usage.

first of all you do not need a rom that is based on battery life..all roms are the same with just few different modifications to it. choose a rom that YOU like and not based on what other people tell you. Then you can do a few things to get better battery life. as the poster above me stated you can do what he mentioned..but i still with autosync on, GPS on and autobrightness i can manage to get over 3hrs screen on time and over a day and a half battery life. Go into settings and sound and untick touch keypad sounds and lockscreen sound and dialpad sounds...come out and reboot the phone..you might think why but trust me that causes drainage to the battery and keeps the phone wake when the screen is off. second if you use twitter and facebook i would suggest to use them only when you log in..do not have it on in the background. if you still need more help PM if you like
but search for Touch Xtreme rom by Smarberg...that is a good rom based on battery more than anything else.

Im sure all the official updates are done. I use wifi in house and 3g when outdoors. Ive got bluetooth and gps disabled and as of now my screen is off automatic. Ill keep charging like you say to condition the battery but can you overcharge it?

I'm on stock and my battery seems to be OK.
The multitasking on another hand is shockingly bad.
Please someone give me aokp or cm9

I fixed multitasking with an init.d script that lowers the low memory killer values. All the apps stay in memory now without closing... like they are supposed to.
Some say HTC set the values so high to save battery, but that is crap. No power is used when the app is held in memory, infact less is used as the apps aren't constantly being opened closed and reloaded. I think they just messed up.

CM10 Performance

I've been running the 9/15 nightly, and while I haven't had excellent battery life, it has typically lasted around 8 hours or more. Today was a little different; with only an hour of screen time, my battery was down to 30%. On top of that, it usually takes 3 or 4 presses of the home button to wake my phone up.
EDIT: I forgot to add that my screen usage usually accounts for 60%, or more, of my battery usage--and that's with minimal usage. It always seemed like my screen was draining the battery even when it was off. It is much less now.
I read on the forums that a simple increase of the minimum frequency can resolve the waking issue. However, it didn't; instead, my battery life improved dramatically. I'm used to a pretty jagged and sharp battery graph, but now it's as smooth and linear as I have ever seen it.
Can anyone explain why raising the min freq improved my battery life?

Why don't you update? Its Oct 5th. Maybe give that a try? Old build man.

Well, I've considered it, but I always check the main thread first. It always seems like people are having LTE or GPS issues with the new build. Everything, aside from the battery life and screen waking, has been working exceptionally well. Not to mention, school and work hasn't given me enough free time to experiment with the new builds. I might try this tonight though.

The rom actually updates EVERY DAY you have missed many many updates here is a changelog http://changelog.bbqdroid.org/#d2att/cm10/1349329973

well all devices are not created equal. i suppose its possible that the ideal minimum frequency for your device is a above stock (or whatever you had it at before). raising the minimum frequency can improve cell connection, screen flickering issues, ect (things that cause battery drain).
also i advise you to update your cm build. either that or switch to cm monthly or another rom that doesn't push out critical updates every night. Try a rom that is considered stable like liquidsmooth, slimbean..

On the Oct 3 build and it's very fast. Batter life has been quite bad, have to charge it twice a day. Had a lot of crashing yesterday, phone decided to reboot continuously. Apollo has stopped error persisted until I cleared cache, and keep getting email/exchange devices have stopped errors until I disabled email.
Battery is the only thing that really bugs me though
Not sent from my toilet with a soap bar.

@nccu_eagles & @jefferson9: To be honest, I never realized the minimum frequency affected so many different elements outside of power saving. I admit I haven't kept it up-to-date; I'm always afraid to update after seeing some of the bugs people post. Perhaps I would be better off with a more stable release--at least until the semester is over, which will leave me with much more time to dabble. If I finish my homework in time, I might try a few different roms tonight.
@adammur: Those are the type of bugs that keep me from updating.
On another note, today's battery life has been great. My battery would normally drain between 12-20% an hour. Today, I'm averaging 5% an hour with similar usage. :good: Anyways, thank you guys for the replies. I'll see if I can't find something to better suit me.... for now :fingers-crossed:.

Before playing with the TouchWiz Jellybean Milestone 5 (Firefly) ROM by Drew Garen, I was running the JellyBro's euroskank October 3rd nightly along with LeanKernel as well as JuiceDefender Ultimate...
My Galaxy S3 could literally last 2 days with that setup. It was UNREAL.
The problem is, I really actually do like the TouchWiz interface (I know I know, I'm one of the few).
But if ultimate battery life is your goal with the Samsung Galaxy S3... Do a factory reset / cache wipe and install the Oct 3rd version of JellyBro's euroskank for the d2att... Then go ahead and install yourself the tmobile / AT&T version of leankernel...
You WILL NOT be sorry!

What did you increase it to, if you don't mind me asking?

I normally use up-to-the-moment builds (downloading 10/07 ad I write) and my battery life has been reasonable - up to two days total with light use. Seems to me to be a matter of making sure you're not running too many (any?) battery-hogging apps (BetterBatteryStats has been enormously helpful in this respect).

Unfortunately, I was unable to play with anything last night due to homework. I did, however, purchase and install BBS and JD. I'm actually at work right now, so I can't really post much other than a few screenshots.

I increased it from 384 to 486. So far it seems to have helped a lot. I'm actually about to try a couple different ROMs and see how they go. Wish me luck :cyclops:

You are not alone, I enjoy the functions/features of the OTA ROMs.
Notification accessible when in full screen apps, the multi-window screen lets you "clear all" and access task manager&Google Now, the stock dialer has more efficient functions(Displays all calls from a contact if selected, slide right/left to call/send sms)
But going back on topic, I set my cpu to be conservative but I'm not sure if that'll save battery.
I want to be able to game when at work but not have the power-saving setting limit it yet still be able to last me a day. The OTA ROMs' power-saving feature was able to do that.

A long time ago in a galaxy far, far away...
Recently i installed ICJ. Since my Battery started decreasing quiet fast, i remembered a guide from the good old Desire days. It was a really good, indepth view on how to determin
what burns your Battery and how to set up your phone perfectly.
In the last view days i tried applying some of these tips and found them more or less usefull.
Since HOX is a Tegra device some things are handled differently. So i thought it might be time to update this a bit and let you participate in my hunt for the best battery performance.
First of: I couldn't find the original guide. So no link here (sorry). I will correct this if i find the right thread. This is all my own work! I don't use any part of another post.
By now this is nowhere near complete, but i'm constantly adding. If you wan't to contribute, PM me and i will consider adding your content (with credit ofc).
Since a lot of testing and time intensive tasks are included here, it may take some time to come to some "final" results. Please bare with me because my phone is my daily driver to.
Introduction
To final start of, i think i should determin the goal of this guide. I hope that this will grow to be a reference for general Powersaving on HOX and finding what is wrong (or could
be improved) with your phone. To be clear:
This is not done in 10 minutes! You need time to test different things.​So you won't be able to read a short post, change three settings, deinstall an app and double your Batterylife! Period! This is a approach of finetuning and getting the most
out of your phone. I don't want 24h Battery life with a laggy non useable phone. which leads to:
Setting your goals
It is crucial to determin what you expect from your phone. Remember: this is a quadcore phone with high-end-graphics. You won't be playing Shadowgun and get 10h of "Playtime"
My personal goals are as following
I plug of charger at 05:10 and come back home around 19:00. I would like to have 15% left when coming home (already done with ARHD)
Usage per day:
3h Music
4h forum reading
some browsing and reading webpages
4-5 phonecalls
a bit of texting (SMS/What'sApp)
a bit of playing with settings and homescreen settings
nearly no gaming and if so then no tegra games
a bit of lag is no problem, but i don't want to wait for my phone to load anything
flawless music playback while screen off
Video playback up to 1080p
no Radio issues (to low voltages can make radio instable at times...)
So all in all no great things, but i'm using my phone a lot and have high screen on times. But i'm not pushing the tegra chip to it's limits (not nearly ) I think my goal is
realistic. Remember that your goal should be doable. Just think of what you expect, and you will see relativly fast what can be done and what can't. So what are we working wwith?
My Setup
Just to give you some insight, and to make values comparable, i give you all the relevant information about my setup. You might skip this paragraph if you're just after the tools
and techniques.
My Phone
HTC One X (Obviously)
Black one
Vodaphone Germany Branded
not on JB hBoot
Unlocked
TWRP
No obvious Hardware faults
I got mine relatively early and have one of the first badges...
My Software
atm (16.10.12) IceColdJelly 3.0
Android 4.1.2
Nova Launcher (No theme)
BB10 Lockscreen Mod
NCX Kernel (comes with ICJ)
Apps (most recent used, Basic Setup. The Core i use. Others come and go ):
Airdroid
DB Navigator
ES Explorer
Noom
S-Finanzstatus
Tapatalk
Titanium Backup
YouTube
Gapps 20120726
Rest is stock and preinstalled
Other things relevant
I Use HTC standard charger with original HTC USB-Cable
most of the time i don't use a case, nut now and then i have a HTC Flipcase installed
No other accesoirs (No Bluetooth things, no BlingBling or dock or anything like this!)
...
General idea
The idea is, to determin how much current is drawn on a fresh install without apps and only google account entered. After that i want to determin what apps/accounts/settings draw
how much power. I will start from my current setup (see above) and not with a clean install. Reason for that is, that i want to give you a guideline to follow. I think most of
you have your phone setup ready and need more batterytime now.
Atm i'm not on Sense and until there is no universal JB Sense for all CID's i won't go back. So right now, you Sense user might be able to follow parts of this guide but settings
may vary. So you might have to get your head around that for yourself.
Preparation
No, finaly, we dive into geting our hands dirty.
You will need some tools and apps to measure different things. I highly recommend using the apps i use, because they are on the market for a long time, they don't draw aditional
power while in background and i use them for nearly 4 years now without problems. Also no adds, which is great because adds are one of the things that rape your battery like mad!
Things you'll need
A wallcharger (USB on a PC will work, but increases the time you need for this process alot)
Apps
BetterBatteryStats (free Version on XDA. Link will be added later)
CPU Spy
Current Widget
What the apps are for
BetterBatteryStats gives you an overview of what is using your Battery/CPU. Not as clearly labeld as the System option, but much more in depth and highly usefull to
determin which part of certain apps draw your power. Also you can see if your phone goes to deepsleep.
CPU Spy lists all CPU Frequency steps and how long they have been used. Again, seeing if your devices goes to deepsleep and if an app keeps using the CPU more
then it should be.
Current Widget is probably the most usefull app to date. It shows how much current is drawn from your Battery and writes it into a log. So you can directly see
if a change affected your Batterytime. And you don't have to have your screen on to measure (great plus here )
Reseting battery stats
To start of clean i highly recommend wiping your battery stats. Do do this, fully charge your phone (100% and then wait till charging light goes green, but minimum 30 min).
plug of charger and shutdown your phone. Replug charger and again wait till charging light goes green. Plug of charger and reboot phone. Now your Battery history should
be clear and we're good to go.​
The rest follows as i proceed. I'm currently in the process of investigating and testing on my phone. If you think this guide might help you or others, give a thanks.
If something like this is already done stop me now, before i spend 100h writing this Suggestions or tips for improvement are welcome and highly appreciated. If i made a mistake or have given wrong information, tell me and i'll correct asap.
Please bare with my english and my spelling since i'm from germany and english is not my primary language.
Other than that, bye for now. Enjoy reading.
Thanks to all XDA-Members, Devs and Content creators. I've had 4 awesome years in this forum till now and enjoy giving back a bit to the community.

One spare

And another one (have something in mind for this one )

I'm going to keep my eye on this thread for any unexpected results – I get the feeling it's not going to be this or that etc. I might start using JuiceDefender again, quite an innovative app. Either that or just switch to 2g periodically.

It's not about finding the one app that eats up all our batterylife. It's more of a guideline to determin which specific apps and habbits burn your battery.
For me Juice Defender always used more battery running in background than it saved, but it's up to you to test it, and give me some feedback. Surprise me and i'll add it to the guide

Sorry I missed that point – it's to discover your own personal usuage habits that tie in with (excessive) battery drain. If you want me to run it seperately as like, a comparison then yeah of course. I will reset my battery stats and use JuiceDefender. For how long though?

I think 1 hour of the same activity should be enough to determin a percentage of gain or loss in batterylife.

Well, I have recently installed a new ROM (ViperX) and installed Google Now which has battery drain issues. In the hour tested I've received 10 emails, four texts (sent three) two facebook notifications, downloaded a 4mb app and listened to approximately 16 mins worth of music. I suppose that counts as moderate to high usage. With Juice Defender I am on 89% I was loosing much more than 10% per hour before now.
Hopefully this helps?

Yeah, I have a drainage of 547mA after fresh reboot which is crazy... Google location service is one of the suspects. I'm investigating in that now, which would respond to you saying Google now is draining. I dropped 10% in 3h of screen off which would mean 30h of standby. Sounds somewhat low to me.
I'm in the testing today, and tomorrow I will write part two. Let's see what's to find there...
One thing. What settings did you use with juice defender?

Just had it on 'Balanced' – there is a fix for the battery drain issue with Google Now combined with Sense roms. But the apk decompiling process is a little out of my comfort zone!

Good luck with this man. I was thinking of doing something like this once Faux's kernel 12 comes out of beta, but I don't think I need to anymore

ATM I'm struggling to get consistend results. I have hours where my battery is sucked with over 600 mA idle. And then everything is fine with around 190 mA. All without changes in the last days. Really strange...

190mA is really high for idle
I just installed Current Widget, it doesn't seem to record idle screen-off usage. Battery Monitor Widget is waaay better for recording mAh used. Even works with screen off.

[Q] Cyanogenmod 10 battery life on normal usage.

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.

It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?

Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.

You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

i got a weird battery life yesterday, i was walking from work to home, i started watching videos on youtube, looked at the battery, 31%, after few videos looked again, still 31%, i walked 41 mins with a total of 9% of battery drain, i also played a game for about 25 mins, it was a really battery life.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.

This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?
Sent from my HTC One X using xda app-developers app

Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.

1 road : 2 destinations

I know that its irritating for the pros out here to see a question regarding a BEST ROM. But I am not asking such a question.
I would like the most battery friendly rom for my n7100 runnning stock 4.3 now. The 4.3 has ruined my battery life and I am looking for a way out. I would love to get the single handed operation in all windows from note 3 also.
So once more these two are what I am hunting for:
BEST BATTERY BACKUP
[*]SINGLE HANDED OPERATION IN ALL WINDOWS (NOTE 3 FEATURE)
Hope I am specific here. Could you please suggest me the ideal ROM solution for my situation..

I never could understand people claiming that a certain ROM is better concerning battery than the other. OK, ie. if you have Note 3 apps there might be some SLIGHT difference, but this is all nothing compared to the REAL drain caused by the screen and DATA. It also depends what software you use - you could have best battery friendyl ROM but if you install stuff that wakes the phone and consumes the battery - it won't matter. Also depends how you use your phone i.e. if you play 3D games ofcourse your battery will last shorter tme than if you just make phonecalls. When you use "light" ROMs, with much bloatware removed - battery will be a little bit better but you will lose functionality. But all of this is sooooo little that it hardly matters.
On 4.3, as on 4.1.2 - my battery lasts like 16 hours and then is down to 50%, and then I'm in panic to charge. But I just went abroad and turned off my data because of the roaming costs. And guess what? I had my phone on for 2 days, 1 hour screen on time and the battery was at 60%.
So no ROM will save you if you have A) data on B) screen on. You're welcome to do some tests. But try without ANY installed applications or with SAME apps installed, keeping screen on time same. And you'll see it makes no difference at all or minimal difference at best.
