NEW EVO User

I finally moved from a Hero to the EVO....yay me...stop clapping, all of you, pleez...thank you! Anyway, I rooted and am looking for the stable CM6 that has everything working. can someone provide a link if its available? I only have a few minutes a day to research the forums, other wise I'd keep hunting. If no CM6 is stable with everything working, what Sense Roms are out there with a stable kernel that improves battery life. Im on the road a lot and battery life is important to me, since I am in the air at least 9 hours out of the day and when I land Id like to have some battery left. I have noticed already that this thing drains terribly even in idle state. I started the day @ 6:30 on a 100%. I didnt call anyone and had maybe 8 e-mails come thru and sent a few texts. checked FB for two minutes and then left it alone. it is now 11AM and im @ 28% battery life...no task killers running. only auto killer. i have a ppl widget and calendar widget and of course the HTC Clock and the cubed widget. i am using 3 screens only. What SENSE ROM or any ROM has a kernel that enhances the battery life with a tweak? or is there a kernel that works with the stock ROM, that provides decent battery life?
Thansk for your help.

CM6 and all other AOSP roms still do not have 4G + HDMI + Radio working.
If you don't care about those, go ahead.
As for battery life, KingxKlick CFS works well for me.
These two tips may help you though:
http://forum.xda-developers.com/showthread.php?t=712990&highlight=battery
http://forum.xda-developers.com/showthread.php?t=701567&highlight=battery
They both worked for me.
If you want absolute certainty that your battery will last forever and a day, shell out about $60 for Seidio's extended 3500 mah battery.
It's a bit pricey and adds a bit of bulk to your Evo's back (it requires an included extra battery cover), but it's more than usable.
As for the Sense ROMs, they all do pretty much similar battery tweaks, so it's more about what you like about them in terms of functionality, design, etc.
Hope that helps.

I'm not an expert in CM6, but I can tell you that if 4G is big for you, then CM6 is a no-go as 4G does not work. Also, the FM radio and HDMI-out do not function, but it has a great Bluetooth stack from what I hear. Here's a link to the thread:
http://forum.xda-developers.com/showthread.php?t=735596
The kernel based on the latest OTA update is the one with best battery life from what I've been reading. Also, it has the FPS unlocked already, so that is cool. If you don't care about multi-touch and overclocking the CPU, then you may one to try one of the many Sense roms out there and see how they treat you. However, in your case, you best bet is to get a set of generic batteries and a extra charger on eBay for about $10 shipped and use that for your travels. I took my daughter to Disney World this past weekend, and I took both extra batteries with me so I can watch the Red Zone channel and not miss football. I burned through the OEM battery, and almost through an entire generic one, but I watched TV for hours and used the phone to take pics, videos, check emails, calls/texts, and even a few kids games to entertain my kid during the lines. I have no complaints with my set-up.

XD so the newest CM Nightly (116 i think?) has FM radio now.
So I guess they're moving forward... but HDMI and 4G are what most people are waiting for. lol

Best battery performance

Hi!, i'm looking for a ROM with a good battery life, because, i like to plug on 3g all day and my actual ROM in 2 hours, spends about 20% of battery that's horrible!
Thanks so much guys!
I actually have this ROM: http://forum.xda-developers.com/showthread.php?t=1039257
And 44 radio.

Have you tried LeeDroid 3.0? I'm running that, I'm a heavy user and it works a treat. Plus, HTC Sense =)

The best battery-saving-rom is Redux 1.1.2. for me! Give it a try

Thanks to both, actually the LeeDroid 3.0 haven't shows spanish language 100%, so, it's a "problem" (not too important, but i'm spanish and i like have my phone in my language ) so, i'll try Redux 1.1.2 and later LeeDroid when shows spanish
Thanks!

Htc Desire
it's good and awesome man i think i must go for one.

Tbh I get 3-5mA usage on the stock sense 2.2x rom - so battery isn't bad on the stock roms. What can change is the radio/ril which determine how efficiently the phone handles mobile/wifi signals - after screen usage and wifi this is usually the biggest drain.
That said, I find it looks nice but don't need it all and prefer Redux

+1 for Redux defiently the best battery saving rom i've tried

What do people use to monitor app mA/battery usage?
I've tried battery monitor widget, and system panel; the former show's me - by monitoring every 60s - that something is pushing the battery from 3-4mA to 50, 80, even 150mA usage at seemingly random times (phone idle overnight) - any ideas of an app to shop which these spikes are?
Syspanel is ok, but doesn't show you what causes what usage when.

Battery life is also determine by what's running in the background. I'm running CM7 and I use wifi practically all day. If I don't use that then I use mobile network. My battery life can span up to 2 days or a little more if I'm careful.
Battery saving roms are ok but unless they're been heavily optimized for it, I don't see the real point.

Best ROM I've used is Amethyst. Could easily get 2+ days of usage out of it, but the dev went to a Nexus S, so stopped development on Amethyst, unfortunately.

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.

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...
Gesendet von meinem HTC One X mit Tapatalk 2

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] Battery drain is pissing me off

I love my s3. but once I updated to jb the freaking battery life is so bad.... it is constantly draning withiut me doing anything in it. And today gmail was on the top of the list. I didnt even use gmail today. Can someone please guide me and tell me how I fix this? Do I really need to go back to ics. I go to high school and I never use my phone but still it drains... do I really need to go back to ics? My battery life on ics was amazing but I wantdd this update and now I am regretting this update so much. Please help?

Go to an AOKP rom

It would be worth gathering more info here before moving on to more drastic steps like flashing another ROM to deal with battery issues.
Can you start by posting screenshots of your battery life screens (go here for some examples of what I mean)? The things I'd personally be most interested in seeing are screen on duration and your wireless connectivity; if you're leaving your screen on and/or you're in areas with poor network connectivity (wifi or mobile), those can both tend to eat into battery life in various ways - for example, e-mail apps (this probably includes Gmail, but as I use other mail apps I don't know for sure) can eat battery life in areas with poor network connectivity in their futile efforts to maintain a connection to the mail server.
Apart from those basic drains, you can get a better idea of what's eating battery life by identifying causes of wakelocks, i.e. what's keeping your phone awake when it should be asleep. BetterBatteryStats is my go-to for this. The info it generates is really helpful for figuring out what applications are eating battery life and how they're doing so.
Hope this is of use.

Flashing a rom is not drastic
It was only a suggestion based on all the reports of battery issues with the official JB release.

Icantell you right now I just checked and the kernel wakelock that is preventing my phone to enter deep sleep is msm_otg. How can I disable this?

Some digging on my part suggests that that wakelock is USB-related, though theories as to the cause vary. Some of the suggested solutions I've seen are using a different USB cable to charge the phone, or doing a factory reset.
