Serious battery drain :(

I got my Desire in april and ever since I've never managed to get the battery to last more than a day.
I've tried different ROMs (Defrost, OpenDesire with and without Sense, MoDaCo r4, DJDroid, Neophyte, Pays-rom 2.1) but it's always the same: almost no drain in sleep mode but as soon as I turn the screen on and start using it the battery goes down ~20% every hour. I don't believe that's normal since some people get 3-4 days out of their battery.
For example, today my phone has been on for 2½ hours and lost 43% battery with WiFi on, just surfing the net and using Tapatalk.
The screen brightness is fixed at 30%, auto-sync off, bluetooth off, network mode set to WCDMA only and I have good 3G reception where I live.
I have no clue what to do, maybe someone else does?

I have the same life spend for my battery. I think its quite normal for desire. Unless I'm abnormal too : x

You can use setCPU to underclock the processor or to create rules to make it powersaver.
I (as many other people) have one for setting the max/min processor to 245MHz when the screen is off, so it doesnt waste so much battery. I havent tested a lot, since I did it yesterday but the battery is lasting longer.
Also there are different ROMs that have better battery life...

I'm using neophyte 1.3 now since it was said to give you good battery time but I don't think SetCPU works with it...

I use JuiceDefender. Just by installing the free app from the market, I've increased my battery by 1.5x what it was originally.
With Ultimate Juice installed, I saw an increase of up to 2.5x.
Sods law, I can't purchase anything via the market due to having a Google Apps email account :|

I've tried it but it's not helping since I'm not syncing anything automatically anyway and the battery isn't drained with screen off.
It's when I start using the phone my battery percentage goes bananas.
And btw I know how you feel, I live in Sweden and we don't have paid apps here. Thank god for MarketAccess.

My Desire was acting like that during my first 2 days of usage. The battery was draining really fast even in standby mode. I installed advanced task killers and after that the battery improved. I do not know if it is because this app or there were some other configurations that I accidentally did...
But the battery life right now is way better than before (even lasts longer than my previous iphone 3gs). Hope this helps =D

I have pretty decent battery life and I use the stock unrooted unmodified rom. Some apps completely obliterate battery life. I used to keep eBuddy open, but I found that it kills my battery faster then anything else.

Just downloaded setcpu to take a look. Should I be looking to use the default settings or is there something I should be changing?

Hmm, when you say "just surfing the net", you're actually using WiFI + AMOLED + CPU, which are 3 of the biggest battery drains on the device.
IME, you can get days out of the phone, but if you actually have the screen turned on all of the time (i.e. you're actually using the phone), then 20% per hour probably isn't that insane. After all, that's 5 hours of continuous use, which isn't too awful from a modern smart phone.
Honestly, I think the answer might be "Yes, it does that" and "you'll probably need to charge it during the day". I've taken to charging mine on the way to work and back again (about 45 mins each way) and I'm still at 90% at bedtime.
Oh, and forget JuiceDefender. Yes, it makes a difference...but only when the screen is turned off. As soon as you start using it (and that's what you're obviously doing here), it shifts out of the way. Once I realised this, I uninstalled it...never looked back.

Oh, couple of other notes. Bluetooth doesn't make that much difference unless you're actually using it. 3G uses quite a bit more power compared to 2G. Consider switching to 2G when you're on WiFi. (sadly, no automated way to do this )

i am not using any of these tools.
i have wifi always on 3g on
no live wallpaper and push mail (k-9) with 2 accounts
my battery lasts 1,5-2 days. with phone turned off during the night. 0am till 7am.
i am surfing a lot and writing a lot emails.

Okay so I guess it's normal, I guess I'll just have to fire up the ol' charger a bit more often then
Btw I don't use JuiceDefender anymore either, didn't make any difference other than the widget claiming to have increased your battery time

Here comes a hint:
Turn off ALL unnecessary widgets like "Bluetooth", "GPS", "WiFi". Turn off also "Mobile"-internet widget, and turn it on only when u want to update some apps or check your mail.
I have noticet that "Mobile"-internet widget drains hell of a lot battery, but if u turn it off now and then u will have ure phone, like I had, for 6 days - with one charge!

JPC battery life

I know it ibeta before you all start on me, however 15 minutes of web browsing = 10% loss of battery. At that rate my phone will be dead an hour and half of web browsing
When the phone is just on stand by battery life is fine
Hope they fix this when the "official" release comes out

Wow where did you learn maths?

the screen needs lots of power, processor needs to,
everything needs the power
look it is same like brand new commputer (whit very good graphic card, processor, memory, MB) - you need good and strong power supply without it is crap ...
if you need good long working phone buy something else like :hmm: i dont know what maybe NOKIA with small BW display
no offence

I noticed on the JPC the battery drains soooo fast!
did a full charge while the phone was off today and also deleted the battery stats.. lets see if it improves

I love my SGS and will not being going back to Nokia, also love andriod - just hoping the official release will let me have use for one full day - not too much to ask I dont think

I get 2 days of moderate to high usage with JPC. I think it uses less battery because the GSM signal is better, but the screen uses more power, is always over 90% in battery stats.

For me it all comes down "display on" time.
if using 3G/edge i get 4,5h
if wifi then 5,5h (no difference if im using it during 1 day or 4 days)
JPC is same as JP3 or JMx

Screen brightness
Just thought I'd say, incase you didn't know, the web browser has it's own brightness setting. That could be killing the battery.

I, for one, already set the brightness to the first level for all aplications that have brightness setting, and still the display sucks the battey like crazy, at list with JPC. With other FW it drops even to 40%.

Battery drain was ridiculous with me. The first night I went to sleep I remember my phone was nearly fully charged, when I woke up at morning it had used around 50%... that is, 50% of the battery for around 6 or 7h just sitting in IDLE! When I actually USED the phone it could barely handle 10h with a full charge, and that's with very moderate usage. I had to leave the phone charing all the time to survive a day with it (charging in my car, charging every time I stopped near an AC outlet, etc). And yeah, the funny thing was noticing how exaggeratedly high the screen battery drain was, even though I wasn't using the screen all that much...
Some other symptoms of the high battery drain:
-Charging the phone took FOREVER with the phone being used, took a LOT of time with the phone sitting Idle, but if I turned the off the battery would actually charge very fast... that proved that the phone was draining so much energy even the AC charger (or USB outlet) couldn't effectively charge the battery while supplying power to the phone...
-The phone got HOT very easily...
How did I solve it?
Well, yesterday I decided I would reflash my device. I did a full reflash (as I always do) including a re-repartion. Now the funny thing that I noticed was that my phone actually wouldn't flash! It would always crash at the Galaxy S welcome screen... I have never flashed it using my notebook (since I'm traveling), but I used the exact same procedure I always use with my desktop back home, for some reason it wasn't working. Maybe some corrupt file? I re-downloaded ALL files (that is, Odin with the 803 pit file, and the JPC files)...
For my surprise, this time my phone hanged in a green screen, and it was really scary. I even thought perhaps the Nokia USB cable I was using was causing some kind of incompatibility problem, but that would make no sense at all... so I entered the recovery menu in my phone and reset EVERYTHING, and tried flashing it one LAST time (this time closing ALL background apps in my notebook, to avoid any problems)... and there it went, a perfect flash, as easy as they go with my desktop PC back home.
1st thing I did was a hardreset, and then I reflashed it again with Doc's RomMod V2 (was using V1 the day before), and new hardreset in the sequence. Then I changed as little as possible in the phone configurations, I just turned everything off (GPS, wifi, and even the data connection through the power button shortcut), and went to sleep...
For my surprise, the next day I checked the phone's battery use, it had drained only ~4-5% for more then 10hours, this means it would, at least in theory, be able to last for days and days in this setup...
So I installed my apps again (not that I have many), did lagfix, turned widgets and network connection back on... and it has been working like a breeze, although battery drain can still be considered high, it's nowhere close to being as bad as it was before I flashed it, now at least the battery will last a full day with a charge @ my standards of usage, that's good enough for me...
One thing I did change, I remember my screen setup was always at 10/30min for shutdown, I left it like that because I'm always using the phone in situations where the screen will constantly shut down at my face, and that annoyed me... well, this time I actally left the stock 30 seconds for screen shutdown, not sure if it has anything related, but one of the things I noticed before was that my IDLE battery-drain was as high as you'd expect from a phone that had it's screen on all the time... maybe some bug makes the phone drain screen power even with the screen turn off, let's say if you have the 30min turn-off config, your screen will continue to drain power for 30min (and there you have the reason for so much screen draw in the stats), even though the screen is turned off... despite my hardware knowledge telling me that a black screen should NOT be draining power from your phone battery, you never know how far a software bug can fck things up hardware-wise, so I wouldn't be surprise if that actually DID happen...
I could even try setting my screen back to 30min-turnoff just to check if the battery drain will go back to insane levels.. but the fact is that I'm scared of messing it up again, it's working fine the way it is, why mess it up? I figured out some things that get messed up with this phone appear to only get fixed with a new firmware flash, and I really don't feel like having to flash my phone every two days...
Either way, I hope others here can fix their battery drain... it's just my tip: try reflashing, leave everything as stock as you can (only thing I did was Doc's RomMod v2, and later Ryan ZA's lagfix, none of them seem to be related to JPC's battery drain), and see if it helps...

wth I can only get 3.5 hours max
Sent from my phone so excuse the spelling errors

After a week of using JPC I don't see any real difference in battery usage from the original stock rom and JP3, I charge the phone every second night ( battery is usually around 25% at this point).
My usage isn't that high, I have a couple of notifications running and a weather widget that updates hourly, its my alarm clock, my mp3 player to and from work (about 90 minutes a day), I make and receive 4-5 calls a day and send and receive a dozen texts a day, I check face book 3-4 times a day and on a daily basis someone gets a 10-15 minute demonstration of the beauty of this phone(note: don't let a taxi driver play with your phone whilst in heavy traffic, even if it gets a confession that it makes his iphone look like a piece of crap).
As far as screen time outs are concerned, I set mine at 1 minute but always turn the display off manually when I finish doing something with it including after I have started the music player (btw I use bluetooth headset to listen to music but not for phone conversations).
The highest display percentage I have seen is about 85% but the is usually tied in with using gps or browsing, on a day I don't use gps or browsing display is much lower, on a day that the display is pretty much off it drops to about 10-15% usage.
This phone is the first, of the several pda/smart phones I have owned over the years, that I haven't had to charge every day.

Id battery usage is not a problem for me on JPC, 8hrs idle ( sleeping ) and I still got 100% started to use the phone and it rapidly dropped.. now im playing a 2hr movie and see if i can get it to loop for 2-3 times before it shuts off.. if it reaches 6hrs then i would consider the battery usage the same.

Please turn off the GPS and a-GPS....
You will get a much better battery life.....

[Q] Battery consumption: I need your help for a comparison

I found a very good program for my Motorola MB525 (Defy) for monitoring the battery draining from the market.
It's name is Batery Monitor Widget and it's free.
With 81% of battery it says only 7 hours and 16 minute left without doing anthing!!! The data is on and Wi-Fi connected to my home network.
Is it normal?? In the night in airplane mode after 9 hours it drain 8%-9% of battery. Again: is it normal???
If you can try this application and report your results...I think there is some application that drain my battery!!
Thanks!

Not really a comparison here, just a little story.
Yesterday i screwed up my Defy playing around with some rom. Nothing terrible, but i had no time to re-flash another rom, i had to go to work. So, i pickep up my old SE xperia x1.
After an entire day, 4-5 calls and several sms, that phone drained less than 10%. Then, last night i put the x1 in stand-by, well, that was a real stand-by, no power consumption at all.
Now i'm back to Defy, 2 hours, 15% drained...
All this just to say android is amazing but terribly hungry of power, even when the screen is off, even when airplane mode is on. I don't need a comparison to know about it
EDIT:
you said your wifi was left on, well android is hungry of data too. Even if you do nothing while wifi is on an amount of data still flows, sometimes i can see several mb downloaded by my Defy in a few hours, but no real usage by me. This also contributes, you should try to turn the wifi off or disable background data when you don't need it.

In standby (3g, sync only calendar and contacts) I have 1-1.5% battery consumption / hour. I think this is normal
With my normal usage i have some 20-40% left at the end of the day... also Ok.
WIFI on & connected will consume a lot of battery so I am not surprised.
BTW I also had an Xperia X1 and the consumption was roughly the same as the Defy... In fact more than 1-2 days on a charge I very rarely had on any of my smartphones with normal usage.

last week I was working in the forest for a few days with no signal at all, so I turned on airplane mode: I remember it going from 45% in the morning to 42% in the late afternoon!
(with everything turned off, just used it occasionally to have an idea of what time it was)

It's ok to be an android fan, i like it too, as i said it is amazing. But, battery life is definitely NOT the strong point. I can compare the two phones now, at this moment. Honestly Defy's battery life is a lot shorter.

what's the other phone you compared?

I really don't have problem with Defy's battery life. As far as my memory serves, all cell phones I ever owned (7~8, all nokia, se, moto) could standby (just standby and don't use at all) for a week or made around 5 hours call. In my case Defy can also standby for a week or allow 5~6 hours usage.
I'm on a 2g network (probably helps alot), as I have wifi at home and at work. I have an exchange email, a gmail, 2 yahoo mails, and a weather app, all allowed to sync at default settings. I don't have facebook or twitter. GPS and bluetooth are enabled only when necessary (occasionally). I overclock Defy to 1000Mhz with SetVsel, and underclock to 300 when screen off. With conscious observation over some time, I find that 1% battery is consumed around every:
- 2 hours standby with wifi off; or
- 1 hour standby with wifi on; or
- 3~5 minutes usage (calls, emails, surfing,...)

thats some amazing battery life u got there abc ...what rom are u using?

hey guys, just a quick question. with which setting do you think i'll have longer battery life: 800MHz/58vsel or 1000MHz/56vsel? btw, i got my phone stable at 800MHz/45vsel

I was using the orange 2.2, and am using the finland 2.2 now. Both have similar battery usage.
But I have uninstalled some stock applications which I don't use but keep running in background, like BlurHome.apk (with Launcherpro), InPocketService.apk, ToggleWidgets.apk (with ExtendedControls), WeatherWidget.apk (with FancyWidget), VSuiteApp.apk etc.

You may be right, I had the Xperia X1 something like 1 year ago.
I had until now FSC T830, HTC Hermes, HTC Diamond, Xperia X1, Samsung i7500 Galaxy (my first Android), Acer Liquid and now the Defy. As far as I remember I always had to charge every night (or every 2 nights at best)
Overall I think Android battery life is worse than Windows mobile was BUT I also have more background programs running now than I had in the WM days.
What I definitely don't like in Android battery life is lack of consistency. One week you get30-40 hours at a charge and suddenly 12 hours... Than you have to make detective work: look what new App might be the guilty one, check what's running in background, reboot and see if it happens again, factory reset, etc. I guess this is the price of freedom

Im on uk 2.2 and i get three days at a push i jus have a weather widget on sync every 3 hours.
Iv also undervolted 300/16 600/29 800/39 with setvsel on performance mode and up threshold on 99% and limit to vsel 1 when screen iz off
Im on three uk so im constonly on 3g and use no wifi etc etc with normal sms usage and a few calls through out off 1 charge

There has to be something wrong in your case. I find that there seems no wifi/2g/3g connection. Could that be the problem?

I dont use 3g ..cuz its expensive in my country ..and I only turn wifi on when I need it
And that shouldnt be the case ...I think id loose a lot more battery if wi-fi would be on all the time

[Q] how the heck are people getting 22h of battery life?!

how are yall getting 22 hours of batter life lol
i bearly get 15 on a good day!
If yall could please post the settings you are using.
much appricaited and i will hit thanks to everyone!

the biggest part of battery life is your personal usage and what type of area you live in. If your phone is constant switching between edge/3g/H, your batery will drain fast. I can get over 12 hours battery life at home but when I'm at work I can't make it an 8 hour shift without charging
shortened .... there is a lot more than set up

I get almost 2 days of battery life ( 1day 20 hours). You must be rooted. This are steps you need to take:
1) Recondition your battery, 2) Flash a good kernel (I use Faux's) 3) use a CPU manipulator app like SetCpu, System Tuner, Fauxclock, etc and set it to Conservative and default Voltage settings 4) Be smart about your usage--use wifi as much as possible, and reduce screen brightness. If you stream Netflix over 4G or play Asphalt all day then your battery life will suck.

i use that rom/kernel combo and if I just use my phone as a time piece I drain about that 1-2% an hour..... under light use I drain about 8% an hour.... under heavy use I drain like 13%. That is using my definitions of light and heavy use

As stated above and additional the way you use your phone. What you have installed..what kernel you are using. Stock/hacked kernel(which helps battery life)..believe it or not you can get 16 to 18 hrs on stock kernel. I've tried it. Tip.. Uninstall / Freeze what you don't need. Decrease brightness. Clear ram/cache.. Calibrate your battery. Turn it off let it charge till 100% remove the battery from the phone wait like a minute. Put the battery back turn phone on. Plug charger wait till 100%. You should be good.
Ooh also check if its leaking or bulky which signify bad battery.

Good tip about Black wallpaper. It does help with battery. I take a closeup picture of a black object ( I use my black leather couch) and save it as a wallpaper.

Screen at lowest brightness and barely using it . I have had 38 hours of battery time but in reality if I use it so that the screen is on much then you get about 6-8 hours. Some people say yhey use heavily but they describe playing music which doesnt require the screen being on.

Also if you are in the area where it switches edge to 3g then the constant change will drain your battery. Stay in a strong 3g area no blue tooth no wifi it will bring your battery usage up. I hit 19 hours on full wifi no bluetooth and maybe 30 minutes of talking , 50 sms or so. The main issue is can you go between outlets, if you can then the phone is doing its job. I have a phone charger at work at at home and during the time its not plugged in (road trips) i can get 12+ hours and thats enough time to go between chargers.

like people has been saying, a lot of the screenshots posted don't show how long their display time on is (when you tap display in the battery usage). I think this averages around 3 1/2 to 4 hours display time on (varies on settings). 4 hours display on is extremely good.
Question: i don't know why but my battery usage graph likes to reset itself and only show my usage AFTER it drops from 100%. For example, right now under the graph it says 2hrs 50mins... but on top it says 3hrs 43mins. and yes im pretty sure i've had the phone unplugged after a full charge at 3hrs 43 mins ago... Does this happen to anyone else?

I got 1d 19hrs running beast mod 4.2 setcpu oc'd to 1.8/ondemand. 50% screen brightness with moderate usage.

I believe the graph only gets updated whenever your battery percentage drops. In your example above, the phone had been staying at the current percentage for almost an hour, which is a good thing.

Htc One X -battery life

hello everyone, i am new to this community, sorry for my bad english, i would need some help. i have a htc one x for several weeks now, and i have a hudge problem with the battery life on this device, im a really hudge fan of htc, but im dissapointed, so for example, i have 9/10 lines of battery life in my settings menu, i plug it in , and start playing dead space, after 40 mins of playing the battery actually dropped by 2 lines , and i had left 7/10 lines of battery. how is that even possible??! all the phones i had, laptops, etc that require a battery worked in the folowing order: if you plug it in and took the battery out, it still worked, so if you had the battery in, it both keept alive the phone/laptop/every device on the world, while charging the battery, so if you use it, it wont loose power, but gained it. i wached a lot of videos and posts of people explaning hot to get more guice out of htx one x , and some wore like, well , dont use it too much, or do ont turn on your phone to see the clock cause it will save some battery..... ?!?! well i dodn't pay a ton of money to have a phone in my pocket and not be able to see what the time is, or play something/ lisen to music , without actually noticing that in 2-3 hours i wont be able to make a call, yes its a strong phone, and verry good one, by design, by hardware, and software, but the sad thing is the battery, does anyone have a mirracoulous tip for me? and perhaps others as well... (oh and i charged it as ppl from htc told me, first three times with the battery empty for 8 hrs..)

the battery will run out whilst charging, under heavy usage, because the phone is using more power than the charger can provide.
laptop chargers can handle this, simply because the charger provides more power to it. (and the fact laptop batteries tend to be several times the size of the hox)
you should only find that whilst using a battery/cpu intensive task such as navigation (it uses GPS, data sometimes, and the screen is on) that the charger won't be enough, but for most other things, like general web browsing etc, the charger will do it quickly enough
the screen is what takes basically all of the battery, so you can reduce that by making the screen brightness a bit less bright..
the battery life when the screen is off is incredible. WAY better than any other phone i've had. when the screen is off, the phone uses about 1% battery every 2 hours or so. and that was with wifi etc connected and autosync still switched on.
whether the phone will last you all day or not, depends on your usage. if it doesn't, then either make the brightness even lower, or you can purchase a portable charger. or a battery case.
there's no point saying well other phones have better battery life like an iphone. lets be realistic, the iphone DOES NOT have better battery life. it may have had decent standby battery life, but so does tegra 3, probably better than iphone now. when you actually use an iphone, or any other smartphone for that fact, the battery disappears just as quickly as this one does.

Tegra 3 standby is awesome. Just tried an experiment. Please note that this is with 3g or WiFi on all this time and with auto sync.
Again this is just to demonstrate standby time.
For the op, are you sure you don't have a rogue app? Also are you using an HTC charger?

i know stand by is awseome, and i am using the original out of the box charger and cable, but i might go ahead since i know a thing or two about electronics and modify the charger at 2 amps vs 1 amp currently.. this will give me faster charging, but im still researching, cuz i have second toughts
p.s. do you have a costum rom? it doesent look like a prtscreen from htc one x

Unlikely. Unless the phone knows it can draw 2 amps, it has to assume a 1A capable charger (designated by connecting the data pins together).

dude calm down ) lol im a student at mechatronics and robotics, i make robots, and work with voltages and intensity, yeah, normally i don't tweak this kind of things, but a battery does not cach on fire or explode, ony batteries from cars and up, not small ones the worst that could happend is it will heat up, and if let alone, will pour battery acid, wich is not dangerous like car acid , cuz is in a verry small amount and it just needs not to be handled by unprotected hand.
p.s. since im new, cant post alot.....

ok, not doubting you, i know it can do this, but let me ask you and be honest, how much did you use the phone, in this 11 h, what did you do?

I used it all 11 hours. Mostly reading second book of Game of Thrones in Kindle app. Checked some net sites, xda forum app, some blogs. Few calls and texts. All the time on wifi. Was sick in bed. Auto brightness, but as my eyes didn't liked strong sun is can say that it was quite dim inside.
But it probably depends on usage. Yesterday I was reading on the beach and I had 4 hours screen on time. Probably brightness all the way up as it was quite hot sunny day.
On normal day I get 4-5 hours screen on time.
Full stock One X.

batteries nowadays can resist pretty much, and unlike a laptop battery that has a chip in it and it records every charge, and then after x charges it suddeny stops working correctely this is cuz of the company chip they insertet to make is useless after x charges, a phone battery is just a normal one, this is tested, i opened a laptop battery and took the chip out, and via com port on pc, i was able to retrive the data storred by the company that produced it, but was not able to reset it, (comsporacy) lol . so i will buy a htc battery, not necesarry one x's and i will test it my charging it a couple o times bowth with the amp maxed, from 1 to 2 (1,1..1,2 etc) and voltage from 5 to 10 V, maby ill get a result, that is a little better than the technique i saw a couple pages away about charging your phone, then powerring it off, charging it again, then pwr on charging it again etc, forgot the method name, but in my opinion bubjecting a rechargable battery to so manny fluctuations of current in so little time does not sound good, my idea of amping the charger or the voltage by just a little sounds a little better in my opinion

You scare the **** out of me. Please don't do this indoors or near any other living creature. You know nothing about charging batteries and are going set your lithium ion battery on fire.

you have a lot to learn then.. Batteries can explode, and they do: here's a video of some guys iphone setting on fire in his back pocket, turned out to be the battery that caused it.
http://www.youtube.com/watch?v=AIRXDeEzlcw&feature=youtube_gdata_player
That isn't my pure reasoning behind my thoughts anyways, whatever experiments you do with higher amp chargers won't do anything, because the phone won't accept more charge than the circuitry allows. Which happens to be a safe amount for the battery. This is so the battery doesn't get damaged, and in some circumstances, set on fire or explode.
If you take the battery out and start prodding things at it and take it over its limits, be prepared for fire or explosion. Like Ben said, put yourself and only yourself at risk if you choose to do it.. And be wise and have a fire extinguisher ready.

Battery life on ViperX 2.6.0

I've been having the same issue as well. The stock ROM on HTC one X drains the battery rapidly. For me, In normal day which includes listening to music, playing games, browsing and making calls, my battery would last maximum up to 20 hours; meaning that every night when I go to bed I had to charge it for the next day.
This problem was battling me a lot. I learned that the stock ROM is taking advantage of all (4) CPU's and memory even while in idle. The whole battery consumption relies on the CPU usage and Memory management.
I moved to a custom ROM called ViperX 2.6.0. I'm very satisfied with the result. It seams that they've managed the CPU and memory in a very good and neat way. The ROM has a lot of tweaks.By default, when installing the fresh ROM and wiping the battery stat, the battery would last one and half a day. By doing a number of simple tweaks such as disabling the animations on transitions, disable fast dormancy and disable smart sync you can have the battery up to two days.
Check the attachment, it's a screen shot of my battery usage.
Hope this helps.

How the hell are you getting this much screen time ?!
I dim the screen to the lowest brightness and disable
sync and sometimes in flight mode, and I can hardly get
3h of screen time! I mostly read on it, so it shouldn't
be battery intensive.
oh, and If I use it outside it lasts even less 2-2.5h.
What's your secret?
Oh and I use the latest CM10, and downclock my
cpu to 800-1000mhz

Then your phone is knackered.
I can get 4+hrs screen on time with auto brightness, auto sync, stock cpu levels with wifi on.
That's no secret, that's just what it does.
As for 'just reading' - you can easily get over 13hrs screen on time with lowest brightness & flight mode - I've tested it myself on the Kindle app.

AOSP roms get much less battery life than Sense roms, 3hrs screen on time is about average.
I'm currently running CM10 with Neo kernel 7.2 @ 1.3GHz and getting almost 4hrs screen on time. With Faux kernel it was usually around 3hrs.

Chrisjcks, what do u mean by "your phone is knackered"?!
Its a new phone! I just got it 2 weeks ago.
Michealtbh, it may be somthing with the APOP rom, but I really
hate using sense ... I want to try this Neo Karnel first,
Can I just flash it on my cm10? (without wipe)
Where can I get it?
How do I know which kernel is im my current rom?

Your phone is fine.
You can find it here http://forum.xda-developers.com/showthread.php?t=1873615
You have to flash the boot.img through fastboot then the modules in recovery. You're probably using CM10 kernel atm

Ok, but don't moan of battery if you are running a beta (alpha) custom rom.
The HTC ONE X battery is fine, especially after the sense 4.1/4.0.4 upgrade from 2.17
Sent from my HTC One X using Tapatalk 2

Michealtbh, Thanks!
I'll try that soon. (it's stable, right?)
I'm now testing the new Nightly.. it's real good and battery life,
seems promising, looks like I'll get 3.5-4h of screen time there
(No sync with low brightness though)
chrisjcks, I'm not using alpha roms, just the stable ones.
and this DOES feel very bad battery life to me, I come to the hox
from Motorola milestone, and there I could easily get 7-8 hours
of screen time with wifi. (and it has smaller battery and 40% overclocked!!)
How much do you get on the new stock?
When I was on stock i remember it ran out after half a day,
only using it for music and taking some videos.

Battery life varies a lot. On stock in London I get a full day screen time of around 2-3 hours with 3G on all the time. Which for me is fine.
Last weekend I was in Portsmouth and the signal was very patchy and my phone died within 10 hours. Hardly any screen on time.
So it does really depend and will vary for user to user depending on your signal and how the phone is set up.
Mine is usually on auto brightness, and auto syncing on.
Today I've been at home as I've got a damn cold but my screen on time is over 4 hours in good signal and wifi. Same setup. So you can gather from this that signal, data used, etc can affect battery life in many ways.
