Jelly Bean Draining Battery - HTC One X

Hey,
I recently unlocked my bootloader, rooted, and installed CM10 on my HOX. I did a full battery drain and then full recharge before using, and still noticed that my batter is still being drained at a worrying rate. (3 hours gone and just 57% battery left) The screen takes 52%, but the Android OS takes 21% and the Android System takes 5%
Is there anyway I can reduce this battery drain? I understand the ROM is still in Alpha, but I've heard people still achieving 3 hours screen time with it! Maybe something to do with getting a new efficient kernel ? (I'm still new to all this).
Many thanks in advance

Firstly, what kernel are you using?
Give it a few days to settle in first.

Stock kernel I presume :/

Try another kernel after a few days of letting things settle in.

hi there - just a thought of sharing with you since you've already rooted your phone -
- Domination ROM CM10 thanks to Owain94 check it out on the forum http://forum.xda-developers.com/showthread.php?t=1799375
- NCX 0.99bOC kernel by n3ocort3x see comparison here done by nimrodity (thank you guys) http://androidroots.com/king-of-kernels-kernel-comparison-htc-one-x/
Again it's a custom ROM expect for some bugs to come up - but you decide at the end since this version are better than alpha
Enjoying the flexibility & efficiency of the battery life on my HTC One X!

[Q] G2 ROM on Desire Z = Lower Battery Life?

Guys,
I've been jumping between ROMs since rooting my phone last week and one thing I've noticed is that my battery life takes a big hit when I'm using the G2 ROM.
You'd think that since it's a lot closer to stock Froyo than the Bell Desire Z ROM it would have better battery life, but that not what I'm seeing.
With both ROMs it seems that they will stay at 100% for a two or three hours and then start coming down - however it's much more dramatic with the G2 ROM and it seems as though it's battery drain gets accelerated.
Has anyone else noticed this?

For my part, while using CM 6.1RC1 the battery drain was amazingly bad.
Under Modaco G2 ROM, it's more reasonable. For casual use for 7h since being unplugged, I'm at 76%.

My phone's been unplugged for almost 7hrs and I'm at 85% battery on my original Bell ROM.
If you have Spare Parts installed, check Battery History. From there click on the "Running" bar. This will tell you how much time the phone has spent "awake" (this excludes the time the display has been on or while on a call).
I'm at 2hrs 18mins (+20mins with the display on).
Give my stock g2 rom a chance and tell me how that compares. I get better bat life out of stock kernel myself. Bet we could use some uv.
I've noticed something new.
I had my SIM card out of my phone today and it's been unplugged for 5hrs with not cellular network (but everything else going via WiFi) and it's still at 99% battery life.
Uptime is 5hrs 53mins with Awake Time at 1hr 36mins.
Is the cellular connection using more battery than it should be?
it looks like a combination of issues.
1. the android system uses a lot of battery
2.cell standby uses a lot of battery but less than android system
i have a unlocked bell desire z.
installed CyanogenMod RC2 but had to roll back to a sense based rom because the battery drain was just too much.
I figured it out, Kik Messenger was the main culprit.
It's been great since I uninstalled that.
To figure it out o had to restore to a clean rom and install one app at a time. At that point id leave my phone alone for a couple hours and check "wake" time under battery history in Spare Parts. If it was more than 10% we had our app.

Some Help in choosing a new ROM. (a few questions)

Hey everyone, this is my first post in this great forum.
I am looking for some help in choosing a new ROM for my HTC desire, the main thing i want to see is the new Gingerbread OS 2.3 and the improvements it brings (battery life), but sadly it has not been officially released to the Desire platform.
EDIT :
Okay now Im on CM7, probably gonna try oxygen later, but till now CM7 suits all my needs and the battery seems good (20 to 26 hours heavy usage) but im running into a small problem.
at 9% the battery dies and phone turns off, battery and phone seem somehow out of sync so 9% means 2% or something, how can i fix this and make it turn off at 2% ?
If it's battery life you're interested in, Oxygen is pretty awesome, but it's AOSP so doesn't have any Sense stuff (widgets, messaging app, camera etc) - there's stuff on the market that provides equivalents/better versions though.
I've just flashed a sense ROM a couple of days ago after coming from Oxygen and I'm missing Oxygen so much that I'll be going back to it tonight It's very fast and stable.
But if you want to stay with Sense, this ROM is as close to stock Gingerbread (with Sense) as you'll get http://forum.xda-developers.com/showthread.php?t=1124810
People have been getting good battery life with that but I've not had too much luck getting great results. It's very smooth though
EDIT: CyanogenMod 7 I can't tell you too much about as I've only briefly flashed it. I remember it didn't feel as "clean" as oxygen but it had a huge amount of customisation potential (though saying that, the latest Oxygen build has almost as much, with the ThemeChooser). Also I don't think CM7's battery life is as good as Oxygen's.
What I'd do if I were you: Flash the CM7r2 HBOOT from http://alpharev.nl/ then flash Oxygen/CM7/SGBS depending on what you want to try first - all 3 work on that HBOOT so if you don't like one you can just flash another quite easily.
Make sure you know what you're doing flashing HBOOT though as there's a risk of bricking associated with it. So just read up first.

Thanks.
I decided to try CM7 7.0.3 for a while and i like it. Alot of customization and some neat features, but the downside is that i dont feel like the Battery consumption has changed at all, its still as i have had my 2.2 froyo stock i think.
I did a small measurment of battery consumtion please tell me if i should be getting these results:
First
-Phone with CM7 rom Charged at 96%
(turned on wifi for like 10minutes, did around 6 phone calls, 1hour looking around settings, animated wallpaper activated for an hour)
After exactly 6hours the battery went down to 76%
So in 6hours the battery decreased 20%
Is this a good result? Will I be getting better battery life in the Oxygen rom ? If so i will definitely switch to Oxygen.
Well that's not exactly bad. I'm currently on 42% after 20 hours 30 minutes with WiFi on syncing emails every hour, a bit of browsing, over an hour of gaming (trial xtreme), some texting, about 20 minutes of calls and some music playing too. Idle it probably uses less than 1% per hour. I'm on the latest oxygen.
I'm really happy with this battery life
I'd recommend downloading battery calibration from the market to get the most from your battery.
Redux is a good ASOP ROM with good battery life - its quite stripped down.
For a sense ROM - I like LeeDroid.

Or completely ruin it. Battery calibration is to be used only if your battery percentage is out of sync with real mV status, so your phone ends up dead at say, 10%. It is not to be used to decrease battery consumption, which is not going to happen. Ever.
To OP, it boils down to your preference. I couldn't care less for ota updates, but if you do, flash ruu, or maybe even rooted stock would work, I'm not sure about that though. As for battery consumption, you had 1 hour screen on, some calls and texts. I'd call that fair.

Yeah you're right. I meant battery monitor widget. It was late at night, forgive me
Battery monitor widget gives you a good idea of what your drain can be attributed to so is a very handy thing to have on your phone. Battery calibration (as the poster above mentioned) is to line up the amounts your phone reports with the true amounts and should only be used if you're getting strange shutdown occurrences etc. Sorry about that
Some people use juice defender too but I don't really like it tbh.
Yeah, those placebo apps are the best
Juice defender, setcpu, task killers, memory menagers etc share the same place in the Hall of sillyness.

To the OP (not erklat)
If you flash a carrier RUU you're all set for ota UPDATES.
If you de-branded the phone yourself, you can still get ota updates, just make sure your goldcard is installed prior to installing the update. If you update without a goldcard you will lose your data connection
If you have a rooted stoc, same as erklat's opinion, I think it should work but I have never tested this myself.

No i read this method and many users are reporting battery damage. I dont want to do this. My battery on regular use (calls, wifi, games,browsing) lasts 26 hours max and on idle it could last like 40 hours or more maybe.
Its just that the phone is turning off at 9% battery.
I used the Battery calibration app suggested before by cgmorris89 but then erklat said that it would ruin things.
What can i do to make my phone turn off at 2% ?
Oxygen every day!
Try MIUI.us!
Miui is using cyanogenmod kernel and base over which it gives great launcher and best default sms and phone apps.
Firewall and white/black list call blockers are included also.
If you can live with english locale, of course.
Sent from my HTC Desire using XDA Premium App
Thank you guys, yes i will try Oxygen and MIUI later on, but now im testing with CM7 and i have this battery percentage problem. If anyone has a solution to this, will be very much appreciated.
And another thing, should i update my Radio ? i have 4.08.00 something, is it safe to do so or might i brick my phone ?

[Q] ROM with best battery life...

Hi, just wondering if someone can tell me which ROM is best for battery life. I'm currently using blendkernel, is there any particular combination of kernel/ROM/baseband etc, not fussed about overclocking, just purely want it to last!!
Thanks
From my personal experience, the stock rom is the best for battery life, though I've switched to using arconium since it's just a tweaked version of the stock rom.
There's a few out there (that are just a tweaked version of the stock rom), so take a look in the development section and find one you like.
Using the stock kernel sometimes makes a difference as well (it did for me) so you might want to try that as well.
For me, using blendkernel, the ROM that optimizes battery and is 100% operational, is 【ROM】【LT15I/18I】Xperia_AniKing_v1.0.0_Ice Cream
for me till now i used only one room it's MIUI and till now it's fine
Ok, thanks for that, I'm going to give the Aniking ROM a go and see what happens...

Can the blendkernel (original for MIUI) be used for any other ROM? Like stock ROMs or even CM7?
I always thought that blendkernel can be only used for MIUI based ROMs....
I'm using the kernel from this thread
http://forum.xda-developers.com/showthread.php?t=1278760
Seems to work fine with most ROMs and I've found the battery to be much better than using Doomkernel...
Hi,
Just a few days ago I've installed the Miui rom on my lt15i as posted on
http://forum.xda-developers.com/showthread.php?t=1528924 with the 2.6.32.9-BlendMIUI kernel by Jason Stein. However in these few days my phone has to be charged every night after being unplugged for about 20 hours.
Today in 16.5 hours my battery has dropped from 100% to 15%. Most of the time the phone is in sleep mode and I've measured that the battery drained about 3-4% per hour while in sleep mode. The phone synch with 2 google accounts in the background and the screen brightness is set to 25%.
For the rest I've made a few short phone calls (about 10 minutes of total talk time), browse the internet for like 15 minutes on the internet forums and played about 10 minutes of Coindozer.
Is this kind of battery life normal when running the MIUI rom on the BlendMIUI Kernel? In "Battery use" in "Battery settings" I got these stats:
Cell standby: 42%
Voice calls: 21%
Phone idle: 10
Display: 9%
Wlan: 5 %
Opera Mobile: 4%
Android OS: 4%
The rest are just about 1-2%
Seems like I'm better off with the stock rom as most of the time I can get about 30 hours using the phone before having to put it on charger. Now I can only get about 20 hours
Anyway I would be happy if anyone can give me advise how to get more battery life out of my phone while using the Miui Rom, cause it's working quite neat in my opinion and looks very polished.
Regards,
Albert

You can try to undervolt cpu supply if your kernel supports this feature.
Also try to flash baseband libs (only for -36 and -64).
I prefer the stock based roms.. I personally like the XperiaMod but I have been using Arconium 8.0 from last 4 days and its battery drain is just awesome!
If u wanna have an ICS one, simply flash the KA 10 Ice Cream Sony.. Simply the most stable and best ICS rom till date!!
Hit Thanks if I helped u..
I recommend Arconium 8.0. It is basically the rom your phone came with, but it's a tweaked version of it.
I also found Miui battery friendly. I've been using DiMiui for a couple of weeks now, and I can't complain.
Sent from LT18i @ Xda Premium
Well, I just got hinted that it is possible my battery needs to be recalibrated. Last time I flashed my rom, my battery was not fully charged. I've looked up on internet and indeed some articles states that everytime you flash your rom your battery have to be fully charged to avoid this kind of trouble. I'll try recalibarting my battery.

[Q] High battery drain because of Android-System

Hello,
I have a high battery drain because of "Android System". I lose about 3-5% per hour of my battery in idle state. I turn screen off and didn't use it.
I'm using Slim ICS ROM with franco kernel #174.
Badass Battery shows me that following included processes are in Android-System:
Code:
com.android.systemui
system
android:ui
com.tmobile.themechooser
surfaceflinger
com.android.settings
servicemanager
So anybody know what's the problem here?
I'm already disabled Google Photo Sync, NFC and GPS because I didn't need that. Also googling for the problem doesn't help.
Hope you can help, thanks!

Again, I've mentioned this twice today: Bullsh**, I don't mean to be disshonouring, or anything, but please, give proper answers,. It's all good, that you want to help, but only with proper and correct answers.
Right, back to topic;
Go into your dev. settings, and uncheck everything that doesn't need to be checked (Stay Awake, Strict mode, etc.) Undervolt the CPU, that should save a ton of battery charge, and underclock to 900-920 MHz, that is definitly enough, on a dual-core
Thanks for your answer =)
I think my phone is already undervolted through Smartreflex in francos app and I also tried underclocking by setting max cpu to 1036 Mhz (instead of 1200 Mhz).
The problem disappeared after 1-2 charges (don't ask me why..).
And now after flashing Slim ICS 3.9, battery time seems to be ok (for me at least).
Per hour in idle state the phone consumes ca. 2-3%.
I ask myself how do others get 1% drain over night. Is that even possible? Tried very much kernels (franco, trinity, glados and leankernel) and didn't even get near that.
Any tips?
OP Im glad you mentioned the issues went away after a few charges. this has been an issue for some who do not believe that a few charge cycles does anything. well im with you as i always see things sort of "settle down" after a few days of flashing a new rom.
I have the same problem on my Nexus S.
The process consuming battery is surfaceflinger. I can see it on battery screen before the name change to Android System.

Yes, it is possible. I get 1 or 2% drain overnight with wifi and mobile data disabled, and up to 5 to 6% if mobile data is enabled overnight.
My record with it is 1 day and 20 hours from 100% to 3%.

I would like to achieve battery drain like that, seems like what it should be.
I am running AOKP Build 2 and I feel like my battery life is ok but not great. I let my phone sit overnight last night with sync off, but LTE on and it drained roughly 4% an hour. I actually turned off LTE in the middle of the night to see if there would be a difference, and no, it drained at the same speed on 3G as well. I live in an area with pretty good reception actually, GSam says I spend the vast majority of my time with a signal strength of 4/5.
GSam reported that roughly 34% of my battery drain overnight was due to Phone Radio. Another 52% was due to app usage. Drilling into that it tells me that over 40% of the battery drain from apps came from "Android System", "Phone" and "Kernel". Under Android System, which was by far the greatest drain of the apps, it only kept the phone awake 1m18s overnight so that doesn't seem excessive. However, I'm confused as to why, with a good signal/connection my battery would drain at nearly 4% an hour whether connected to LTE or CDMA. Unless the radios in this device are poor, I have a hard time believing there isn't a way to fix this without using something like Juice Defender.
I can't recall because it's been so long, but I don't really remember any ICS ROMs draining this fast. I'm on a clean install of AOKP B2 and I've tried a few different kernels with the same results. Any ideas anyone?
So I wanted to let you all know that after trying a few different ROM/Kernel combinations all with similar idle battery drain, I installed the latest (9/21) CM10 nightly and I only lost about 10-12% overnight last night connected to LTE. That is a much better drain than the 30% or so I was seeing previously. Not sure why but my phone just hasn't been handling the latest AOKP builds very well. I am afraid to try a different kernel right now as I'm leaving town tomorrow for most of the week so I'll leave it as is until I get home next weekend, and see if I get this good of battery life with the latest Leankernel.
Surfaceflinger
The same happens to me, this app appear in BetterBattery stats, Surfaceflinger appear as the culprit of my 45%+ battery consumption caused by Android Sys
When I first rooted my phone (xperia S) I noticed an 31%+ energy consumption by Android Sys, I reflashed and re-rooted and stoped for 2 weeks or so, now 2 days ago I woke up to find that 81% of the battery is being drained by Android Sys, then it lowered to 31-43%. I noticed that when I refreshed the stock "Battery" app ,"Surfaceflinger appear for a moment, I seem that I confirmed with the BetterBatteryStats, Surfacaflinger appears at the top.
Why is this happening? Can something be done about it?
PS: I cannot change kernel, bootloader is locked...
Surfaceflinger and android.process.acore are top battery drainer. I mean how to make them not sucking on battery?

[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?

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.
