I know this has been covered in many other threads but they seem to be fragmented into some suggestions for specific problems. Researching, following and applying the information, tips and software some have suggested I am still getting nowhere. My battery dies in a very short period of time - something like 4-6 hours.
I have installated, executed / implemented many of the suggestions and procedures here and on fuze-mobility to extend battery life. These are representative. I think there have been probably more but I cannot remember them.
HTC Power Management
SD Card Battery Saver
Taskmgr - to kill / stop Activiesync (replog.exec) from continuously cycling
Advanced Configuration Tool to turn on and off 3G
Registry Edit modifications on both the Fuze and associated laptop related to Activesync Update cycles
Activesync - added new server, made timing manual, deleted server.
Charging processes - Letting battery run all the way down to below 10%
Lowering brightness on my screen
I have ordered and am waiting for an extended battery for the Fuze.
The only thing I see is when viewing what is executing via the Taskmgr CPU Usage panel, I see that most of the time the Idle process is executing. (75+%). Although I have read some threads where folks have said this is good because nothing else is draining your power, just because the process says "idle" does not seem to me to be doing nothing..it is still cranking through and using cycles to go through its designated activities.
Is there a way to indicate the interval when the idle process cycles?
Anyone have this same situation? Any suggestions?
That sounds very bad. Most complaints are about it being less than a day, noy 4-6 hours.
Have you contacted HTC/your supplier to get a replacement battery?
Also, idle is not a process, it's the absence of a process...
I'm not an expert on the ARM architecture, but idle processes are processes that use the CPU when all other processes are waiting for something or when there are no other processes running. They don't necessarily do anything constructive (they essentially just 'mind' the CPU until another process needs it), but they often feed the CPU with power-saving instructions. In conclusion, ignore it - it's not causing any problems and there's no point in fiddling with it.
That sort of a battery life is absolutely ridiculous, and you've clearly had a good go at increasing it, so I my best guess would be that it's defective.
Thanks for the quick responses.
I would still like to investigate the "idle" process angle. As long as something accesses the CPU, cycles are being executed and power is being used. Depending on what the "idle" process is doing with the 75+% "time" it has control of the CPU lots of power could be being used / drained.
Not sure how to go about this yet but I'm sure there is a way to find out what is going on during the "idle" process time holding the CPU.
If anyone know please share.....
Wow, it seems like the battey life on these things just keeps getting worse and worse. I remember going from the Hermes to the Kaiser and thinking how much worse the battery life was on the Kaiser.
The features keep increasing and batteries are having a hard time keeping up, I think.
there is alot to blame here. the good news there is a fix for almost every culprit.
1st....touch flow 3d. this thing demands alot of battery life. Not too mention its always running. Att has also seem to have added a few things to the touch flo interface that may have had an impact on this as well.
2nd....the applications these days seem to be getting bigger and bigger every few months. its not uncommon to see an app eating up 7 to 10 mb of ram. jivetalk...opera...the new aim??? the thing about this....the more ram an app takes up, the more batt power is consumes.
by the way...this is not a problem native to windows mobile...take a look at Google's g1....the batt life on that phone is even worse than your stock fuze...and after i've been digging through the phone....i found out all the apps are over 5 mb....madness! Also, the iphone has had this problem....and still does. but the iphone doesn't allow for background processing....so large programs running in the background aren't really that much of an issue.
3rd...att! in a noble attempt to cram the fuze with everything under the hood and give it the title it truly deserve (a phone capable of doing everything) they've weighed the os down with crap ware.
4th...the att radio that ships with the phone....its horrid. you'd never belive how much better some of the other radios are vs. the shipped att radio. its almost ridiculous that att would ship the phone with such a poor radio.
5th....htc. The batt in the phone is no bigger than the one offered in the tilt. But lets keep in mind, the same size batt now has to power faster processor....more ram...and a brighter more high res screen. Why they didnt up the power of the batt? who the hell knows...i guess to keep the phone nice a small...but its def a trade off.
I want you to try a cooked rom....try romeos 1.4 or the new proven.....change your radio to the shipped orange....make sure you spl before doing both.
and post back. im sure you'll have a different experience.

I'm going to save you a ton of wasted hours in your life....or at least give you something else to waste those hours on. Stop the witch hunt on the "Idle" process. Open up the task manager on your desktop/laptop and look for the Idle process on there. If you pay attention (and do a little guessing), you'll see that the idle process consumes the remaining percentage of the CPU after the other applications have had their cut, however if you look at the total usage, you'll see that it doesn't include the Idle process.
There's a reason for this. It's lying to you....
There is no "Idle" process, it's just a way for the operating system to indicate how much processing power is not being used by applications. There's certainly something going on during those empty cycles, but it's operations that the core of the operating system is doing. Another poster mentioned that one of the things it's doing is sending power-saving instructions, which is basically true (but it's more in the form of telling the processor that there's nothing to do and letting it decide to save power).
The idle process cannot go away, and the closer you get it to 100% the better (relatively speaking, as it means you're doing nothing with the phone and removed any cool features it had). As long as the phone is on there's going to be at least a trickle of power going through the processor so the core of the operating system (i.e. Kernel) can perform it's necessary actions...just like the brain or heart does in your own body, even at rest they are still working a little bit.
Truthfully, I think you're barking up the wrong tree with your battery issues. I've got a Fuze also, and the ONLY time that I saw the battery die in 6 hours was when I was talking on it for about 3 1/2 or 4 hours in one afternoon. Otherwise, that thing, even on the stock rom, has given me nothing like the trouble your describing. I've flashed NATF's rom onto it (didn't like ROMeOS that much, just felt a little too laggy for me) and the new Austrailian radio .20M1 and the battery life seems even better. I don't think you're doing something wrong, I think you've got a lemon phone. Return it to the store complaining about the battery life on it not matching that of any of the other Fuze's you've seen anybody else using, then get a new one and try that out.
4-6 hours? Consider yourself lucky. I can get that if I don't touch the phone and no one calls. If I use the phone as a normal person might, I can get 2 hours. I don't even consider it a mobile phone. It's stays plugged into something all day.

You have a faulty battery or you don't know how to set up the phone. I'm also using HTC Raphael, and battery lasts 1,5 days with lots of usage. I think that you should search xda for battery tips&tricks, like lowering backlight, turning off WIFI, BT and other. Also, there might be a problem with the ROM and Radio you're using.
The battery was exchanged...twice...the poor battery life was present with nothing but stock apps and all the tips and tricks you suggest were tried, and then some...the problem is endemic with the fuze...I figure as much as I paid I shouldn't have to jump through all the hoops with 3rd party new roms etc. just to get my phone to work like it should...the battery is piece of crap
Hmmm, in that case it could be faulty device - there are plenty of people on Raphael subforum that are using Fuze and battery lasts for most of them 1-2 days.
Whos got Extended battery on there Att Fuze ?
Is it worth the bulk
& which one to get ?
18,00 / 2,000 diff kinds i see

It has been quite interesting to watch all those threads for the above topic which of course lead to nowhere so far.
I would not exclude myself of the dispute, however we need to think of the issue in a practical methodology and thus conclude what the facts would lead to.
There has been many complaints and unhappy people about the battery life in Touch Pro and many other models. Just a simple question I ask; What would be an acceptable avarage battery life with one full charge? I am sure responses will vary coz there is no standard expectation nor a universal benchmark for this issue!
Whatever the vendor guarantees as an operating expectency measured in hours, is more or less what you gonna get although many wont accept it, but this is it, you gotta live with it!
There are 1000s of users with 10000s of applications and conditions that have high expectations, but they all get even results, so why complain?
What I am trying to highlight is if many have expressed their dissatisfaction of the battery life, I just say; who's right & who's not? Do we all expect to have the same results? My device may run for 3 days with one charge and couple of calls throughout, others may have tougher uses and expect a battery to last for 7 days in a row with just one single charge?
Just think about it and have a collective understanding.

ya made a wise statement here.....couldn't agree more ...
yep, 2nd that
a wm device drains a lot more battery than other phones because it does sooo much more. and its not device specific either
maybe if someone creat app to change CPU to 200- 300 and so on if don`t used for heavy apps will incress battery life. In the PSP there is app like this ans when I used it only for play music set procesor to 100 Mhz
I have had the phone for a week now. I like it. I like how pretty much everything works. I don't see much of any problem but the battery life. Why didn't they put a larger battery in. My Mogul has a 1650 in it. Yesterday morning the phone had a complete charge. I went to worship and used it very little in the morning. By noon time where I showed the phone off to a friend who is thinking of getting one, the phone charge was down below 50%. It should have been 70 or 80% and no less, IMHO.
I've posted this link before on a different section.
http://www.hardwarezone.com.au/reviews/view.php?id=2726&cid=24&pg=6
I get nearly 4 hours as well if I use mine full on. Tried watching a full length movie and my battery meter shows ~50% afterwards.
I thought OP might be interested in seeing this review.
I don't think it's really an issue of someone being right or wrong. I think 24 hours is just a particular limit for cellphones, and once it dips below that we start to worry about the next time we'll be near a power plug. After all, these are devices that we use on a daily basis.
If the batteries lasted 2-3 days, then it wouldn't be a big deal if we forgot to charge once in a while (late night, canceled flight, forgot charger, etc). But as it is, people are having trouble pushing it past 24 hours even under modrate usage, which means if they miss even one charge cycle, they're dead in the water the next day.
Of course usage is a different issue; but if you start modifying your usage habits in an effort to prolong battery life, that's still the same problem. You could turn off 3G, stop mail checking, always close background apps, etc; but without any of those features you might as well use a regular dumbphone -- no point in getting a device like the Touch Pro in the first place.
Last week we went on a short holiday. Both my girlfriend and I have a TP running RomeOS v1.13. She has a GSM prepaid card and I have a GSM/3G/H card.
Her battery lasted 4 working days occasionally calling home to check on the kids and sending a few SMS messages.
I used my phone to check email and LIVE messenger. My battery lasted no more than 20 hours.
So if you by a full featured phone, just to use it as a basic phone you won't complain that much I think. If like me you want to use a full set of features pffffffff... And if you don't mind I would like to keep it at that
My first serious WM phone (I don't count the ridiculous HP 6315) was the Samsung i730. I am a very heavy user and I got used to charging it in he car & carrying a spare battery in my pocket. If it made it to 6PM without going dead I was happy.
The Touch Pro has the same screaming 528 mhz processor speed, plus a vga screen. If it makes it to the end of the day, then I'll be more than happy (haven't received mine yet, it's in the mail). There's always a trade off for speed and resolution. I'd rather carry an extra battery than have a frustratingly slow processor.
I've had my TP for a week now and with a pretty heavy usage, my messenger is almost always on, some internet browsing and a little bit of monkey island on scummvm, my battery lasts 2 days. I can live with that.

Which Messenger are you using? I'm trying to find a good Google Talk client that won't drain my battery.
The battery should be expected to last a day. Past that, would be nice, but I do not feel it is necessary...
If the phone won't even last me a day (and "a day" for me is 14-16 hours at school and work) then it really isn't going to work for me. I hate trying to search for 5-10 minutes to have the phone plugged in during the middle of the day to try to extend the battery to make it just past that 12 hour mark for me.
The CDMA Touch Pro doesn't seem to do too well. Sitting idle, it had about 40% battery after 14 hours, but then dropped extremely quickly after that... I must have sent 10-12 texts and was in a call for about 10 minutes the entire day, no programs running in the background, only the cell radio turned on.

I agree with you 100% - except here is the problem: the vendor guarantees (well, doesn't "guarantee", but no vendor really "guarantees") a battery life that is absolutely not right.
On the Touch Pro, Sprint says the phone has a standby of 406 hours - that's 16 days! Incredibly misleading, and in my estimation definitely not accurate. That's the biggest problem I have with the whole battery issue.
Also, in comparison, my Mogul was suppose to have 340 hours of standby and 30% less talk time - but my Mogul lasted a LOT longer than this phone. I could talk, surf, play games, and have it still last longer than this phone. That doesn't make any sense.

Alright, alright, alright! Let's not mention the biggest and silliest gimmick PPC vendors made us believe in specially those of high-end CPU ones
I might have been worng in choosing "guarantee", but who says! When you read "Stand-by" I am sure that the vendor wouldn't in gods name mean "with any GSM/CDMA network"! I mean just think about't!! Why in heavens name would they shoot themselves in the foot by committing such a thing
I could defy anyone who would tell me that "Stand by" is a standard by itself! Haven't you read "The above are subject to network and phone usage" in phone specs?
In addition to the above, network signal strength matters and is very fundemental to extend/shorten battery life too!
Whether or not the battery was of 1300mAh or 1600mAh, it is all the CPU power management and I am pretty sure that Qualcomm is unlike the Intel XScale as the olden memories remind me of
Like most of you rightly said; change your habit and the battery life will change accordingly.
Just a last lil thought, why isn't there a quick options made available in the market for a higher amperage batteries? If one would care about the total gram units, then I recommend to live with the supplied battery.
Let's all cherish the memory of the HTC Universal, that baby was a hot long-lusty orgasmic son of gun device ever was.
I feel the term "standby time" has been used loosely, never in working with wireless phones have I found a machine that is capable of being on this long without being charged. Notice the "up to" that is always there on these kinds of stats too. What does up to mean? Probably something to do with turning off all the radios so the phone can't actually do anything, it might as well be off.
No matter what you do, computers require a lot of power to maintain themselves in any sort of "on" state. If there are any background processes happening (i.e. cellular radio sniffing for incoming calls and sms) you are really only burning power at a rate less than that of radios + screen.
Phones consume more power than phones did even a few years ago, hell they consume a lot more. Does anyone remember first-gen digital phones? 2 hours battery life, talk/standby, didn't make a difference. In fact the batteries used in mobile phones have changed (lion/nicad etc) probably a lot less than the manufacturers' ability to use less power to get the job done.
You can always strap on a bigger battery, but then you have a bigger phone, making it even HEAVIER!
Ultimately, as others have posted before me, that when you buy a touch pro, it is because you are looking for all the functionality that the machine entails. If you use all of the functions at the same time you are burning the candle at both ends. We buy a phone with a gps, bluetooth, wifi, 3g, vga screen qwerty, 3.2mp camera, etc because we need (or want) all of these features at the same time. When you are using the gps while having bluetooth on visible, screen full bright, wifi still on and music playing, don't be surprised your battery won't get you through the day.
I think that the general consensus here is that typically we should be able to get about 1 day out of the pro. Any more, we are lucky, any less, you either have a defective unit or you may have unrealistic expectations of the device.
That being said, after a few weeks go by and you find yourself actually being able to put the damn phone down for a while, battery life will seem longer too
My experience:
I've come from an XScale phone, which runs Linux and doesn't have 10% of what Pro does (like GPS, wifi, 3G, SDHC support, VGA screen, G sensor, light sensor, etc.) and even without all that it doesn't have a great battery life. I had to recharge it everyday sometimes, because I had pretty heavy use (especially A2DP audio).
With the Pro I can do that and much more and still get at least a full day of battery, which for me is good enough.
Tell me one device that has the same size does everything the Pro does with better battery life.
Unfortunately we are still to see better batteries, which I've read a lot about, especially that nanowire technology which supposedly makes them 10x better, but until then there isn't much we can do. So I don't think it's fair to blame a manufacturer, HTC or not, for poor battery life, because IMHO they did an impressive job on making such a small device with so much power, and still manage a full day of moderate use.
I find that TF3D is a real power hog too. Although I really like the interface, I am trying a run with SPB Mobile Shell instead
It is 3:30PM EST now, I unplugged the phone after a solid charge at 8PM, immediately changing to SPBMS.
It is now about 20 hours later and I have 63% remaining, that is a 37% discharge. I have been using the phone normally for the purpose of this experiment and normally the phone would be at about 30% remaining with tf3d.
There is a thread about this here
http://forum.xda-developers.com/showthread.php?t=441767
Hi All,
I'm wondering if besides the GPS, WiFi, 3G and Bluetooth.... the application processor, running at 528MHZ is not a cause for this poor battery life time?
Adrian
The reasons why we read many different opinions is that people use phones in very different ways. I can usually cope with the short battery life but sometimes it is really annoying. It just needs a few hours in a bad coverage area and the battery drains completely. Or an unexpected need for TomTom to make the battery go flat before I get back home in the evening. I used an HTC P3600 (which is a very similar phone from a featureset point of view) for two years and I never had to worry not to listen to music at the airport or on a plane because I wouldn't be able to use the phone after landing. Instead I have had this problem already twice with the Pro... this terrible battery life is really spoiling my user experience with this phone.

Well, as I said in my previous post, discounting the hardware keyboard and the fact that it wasn't a very attractive phone my old HTC P3600 used to do exactly the same things with a much longer battery life.
Is there a tweak out there that stops the stupid battery from guzzling? Im tired of charing it constantly and I swear it takes hours and hours to charge it back to full power. The thing cant last longer than a day without loosing power I cant stand it. Whats making it use all that power? I thought maybe if I switch wireless it would help but I didnt notice a difference.
I can get 2 days out of my battery.
I let it drain to 1% and then stick it on charge over night. When i get up the battery will be at 100% and then 30 minutes later down to 90% but it settles down after that.
I do not have wifi and bluetooth on all the time, just when I need to.

I don't understand people telling battery lost for 2 days..... even if we keep phone idle it will lose power in 24 hrs i believe....try like this try to use ROM with out manila & with manila once you will know the difference other than that there is some tips to save battery in Energy ROM thread in 3 rd 0r 4th post ..
4 days normal usage.
Manila2, GSM
15 minutes call, 6~10 text message, sync exchange, 30 minute ebook reading per day
If I build rom myself from the kitchen. It usually runs for 2-3 days.
However, in most cases when I try decent cooked ROM, for example, Energy - battery drains in about 5 hours. That's been the case with other cooked roms as well.
I suspect that some popular configuration change done by cooks causes battery to drain in certain environments. Would be nice to find out which change is that.
Processes and services often place a strain on the life of the battery; add to the mix a buggy service or application that further shortens battery life and one has an unusable device.
Another habit that can shorten Li-ON battery life is full discharges - near 0%. One of the members put out a thread a while back on research he/she had done on batteries - worth the read if you haven't already.
Cheers,

I just had the same experience, cooked for the first time and my battery was better than it has ever been!
Since then I have flashed to RRE 21731 6.3 and it seems my battery has stayed the same (Brilliant, 2 Days no problem).
The only thing ive done differently is I have used the new UK Voda rom as my Stock Rom that i flash before flashing custom, and i believe this may have something to do with it...What, I don't Know.
I also believe changing the Radio After a flash can affect battery life, I always try to flash a new radio before a Custom rom.
I have wondered for some time wether the European Touch Pro is slightly different to the US Fuze in its hardware, Since most Cooked Roms are configured for the Fuze maybe that is what it is?
maybe we will find out..One Day
turn off 3G and you will get much better battery.

That will ****-up your battery, you should never let it drain to 1%, just charge it when you have the time, preferably before it drains to about 20%.
I guess it all depends on the eye of the beholder, I come from the Diamond part of XDA, and we are lucky to get 24 hours on the Diam.
I was happpyyyyy with my new TP battery life -compared to Diam that is-
But ya, turning of 3g and being picky about processes and back light helps.
Greets to all.
Search the development and Hacking thread for Windows Long Life/save your gonads. Chainfire is developing a neat application to automatically switch from 3G when not needed. I tried an early version and it seemed to significantly increase my battery life.

An app that may help is Advanced Task manager, it has a widget to end all running processes/tasks which i tap before putting mine to sleep about 1000+ times a day it seems. go in and exclude ones you may want to exclude always and then its as simple as 1 click. as everyone else said, no gps,wifi,3g when not 100% necessary. also, get widget "toggle disply" from rounded labs and keep your screen completely dim (not like you can't see it...), being able to make it bright when you step outdoors. Also, toggle backlight app for root users keeps the pesky keyboard backlight off when you don't want it on (suggest making keyboard shortcut for quick toggle). last but not least because i'm sure theres plenty more, but yesterday i switched to cyanogen's newest stable ROM and it seems to be much more effective than any other i have tried in the means of saving battery life. had wifi on after a 98% charge for about an hour and a half (30mn usage) and it only went down to 91%... wow. "and that's all, i have to say, about tha-aat"- Forrest Gump
Firstly I don't think this is the right sub-forum for this question since it's not a specific ROM question.
Secondly, try nueDynamicClock, if you use the right settings, you'll extend your batt life by at least 1/2 a day if not more.

If I build rom myself from the kitchen. It usually runs for 2-3 days.
However, in most cases when I try decent cooked ROM, for example, Energy - battery drains in about 5 hours. That's been the case with other cooked roms as well.
I suspect that some popular configuration change done by cooks causes battery to drain in certain environments. Would be nice to find out which change is that.

It's really very simple. Flash an awesome rom, and the battery burns and burns. Flash a rom you hate, and the battery lasts forever. Don't over-think it.
hi guys.
i was eager to start up this discussion and am glad to find it here itself.
even am really finiky about battery.
tried alot of thing but cudnt find any spcl tweaks.
though i came across some registries from advanced config and other wise also but they seem to be more worse.
;IMPROVE BATTERY PERFORMANCE
[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
“DisablePowerManagement”=dword:0
when i use these tweaks the power consumption of my rom reached to 4.112 volts(as per power detect) which otherwise without these tweaks is 3.992 at startup.
more power consumption i guess means less battery i guess.
and even if its not still these tweaks as per my usage show bad results.
why so?
and arnt there spcl application which can detect the packages which might consume more battery, as i have over 50 packages in my rom and it'll hell to check which eats more.
Some tweaks I do
I have also found for me that disabling these things in advanced config also helps.
Performances
> File System cache: Disabled
> File System filter cache: Disabled
> Glyph Cache: 32kb (advised) I'm not sure if disabling this one is a good idea. I like having a little bit of glyph cache on my device.
Light senor
> Light sensor polling: Disabled.
*Note: If you want to still have light sensor on (this means the auto backlight feature) I would set the:
> Light sensor polling interval: 2000. This will make it poll every 2 seconds instead of every .2 seconds. I would even try setting it to 5000.
The backlight will make a huge difference on how long you battery will last. The brighter it is the more the battery needs to light up that screen. If you turn off the polling all together it will make the battery last longer.
Also running fancy UI apps will also deplete the battery more. Just common sense really as another poster alluded to earlier. The more things you have running and sucking up memory the more battery it will consume. If you disable TF3D or other apps such as this you will get your battery to last longer. Given that these devices are meant to have these types of programs on them you will have to weigh the options of how much you really want to "tone down" your devices to get the most out of your battery.
Also different radios will cause you battery to last longer. I suggest to everybody that they try different radios to see which ones last longer. Also people who live on the edge of 3G and EDGE area will cause the battery to drain faster as it constantly switches in and out of 3G coverage.
WMLongLife is a great app if you don't need 3G while you phone is just sitting in you pocket. It works great for me and when I want to use 3G I simply launch opera and the program will automatically enable 3G once again.
There are many things that you can do to improve your battery life. I encourage everybody to find what is best for them given what they use there device for and try and test things out. The best way to tell which works best for you is to simply try it out for yourself.
**NOTE** I also set all ROMs that I flash with a page pool of 0. I don't know if this has any real effect on battery life but it does seem to make my battery last a little bit longer. Not sure if this is a placebo affect though.
Hi
Have had this phone for just a day.
Been struggling to make up my mind whether I want to get it because of the limited memory.
But finally decided to go ahead because it has good reviews on its performance and battery life.
No complain about the performance, but the battery life?....
Played Tripple Town for just about one hour and 30 mins and the battery goes down from 66% to 35%, the majority of which is comsumed by the screen.
So here is where I am. 5 h 47 m on batter, 32% left, 69% of the power drain is because of the god damned screen.
Seriously HTC, how can you manage to get so screwed up with such a decent processor.
you get rid of the removable battery, ok, nowadays the battery lasts reasonably long.
you get rid of the Micro SD card and force us to use the rubbish dropbox. 50GB 1 Yr cost $99. Why don't spend that money to get us a decent bigger memory? But ok I want the performance, I am willing to give up a bit of space for that.
But Finally SUPER AMOLED. Seriously, what kind of dump decision is this to fit a more-than-a-year old technology to such a decent new processor?? when we know all the bad thing about this screen.
It alone kills all the power efficiency the 28nm processor can offer us.
So now this phone's battery cannot out perform (when you are actually using it) neither of my previous phones: Dell Streak and Atrix. Don't tell me I have to compare the battery life by switching off the screen and just let them sit there.
I am very disappointed. very disappointed.
This will be the last phone I buy from HTC.
It sounds like you don't know about how to manage phones.
You prob was running lots of applications at once and brightness all the way up it still won't go from 66% to 35% sounds like a bad unit you have.
no... the brightness is at it's lowest level.
I use anrdoid assistant to kill process once an hour.
There is very unlikely this is a bad unit. Nowadays these manufacturers control the production quality very good that the chance I get a bad unit is probably as low as winning some lotto.
For starters, your device is BRAND NEW so battery will take about a week or so to break it in, just be patient. Also, killing tasks will only end up using more resources since Android will most likely just start them back up once it gets the chance. Run your battery down the first couple of days and charge it overnight and you will start to notice it getting much better.

Kill Process runs only once an hour. So during the time I was playing, it probably just ran once. I doubt it will cost much power at all.
I understand it needs time for the battery to warm up. But even with that taken into account. it is not looking good. It reminds me the suffer that Desire caused my friend.
Hopefully this doesn't turn into a bigger issue; keep us posted!

sorry mate but this is just stupid. first of all the battery meter is not calibrated in a new phone meaning the reported battery state is not accurate. you have at least to charge the phone once to 100% and discharge it fully to calibrate the 2 extrem states. before that everything displayed is just a rough approximation. at the first discharge i had ~20% left and the phone was down to 0 in just some minutes of heavy use. after 2 cycles i get ~-10% for an hour of heavy use. so stop crying and give the phone some day's to adjust

Well I hope jodue is right: the battery needs time to fix itself.
I will give it a week to see whether things will improve. If not I will go to store to get a new one.
I have been using Android Assistant for my Streak and Atrix. It turned out to be just alright.
Anyway I will remove it and see how it goes.
Ppl have wrong idea that AMOLED is more power efficient. I remember reading a review some time ago on battery life of smart phones. It tested a number of phones and the outcome is that actually on average the AMOLED (at that time there wasn't SUPER AMOLED yet) devices last less than others.
But anyway...

This is the most stupid thing one can do. The processes will likely be restarted by the OS and you consume more power than you would have consumed by letting android do his things as designed.
Google itself suggests not to do it. Even the most honest task manager apps suggest not to do it. (e.g., http://android.nextapp.com/site/systempanel/doc/autokill ).
Anyway, before judging battery life wait few days. I own a One X, and battery life improved suddenly after few recharging cycles. ;-)
About the display. I readed somewhere in this or X forum, that:
1. LCD does consume less power, but for X version, since its bigger screen, it takes more
2. AMOLED screen power consume depends on what it have to display (colors). Black/dark colors need less power to be shown while white takes the most power...
You get 25GB free on dropbox with all one series phones plus a further 25 per referal

This. Many people don't know/forget about this. Using a dark theme on apps you use most on an AMOLED phone can save a lot of juice, much more than all those stupid Juice Defender/task killer/manager apps can ever hope to.

You cannot ask all the website to go dark background can you?
Ppl use the phone to do different things. Games, Browing internet... thats the whole point, the phone should perform consistantly for all tasks, not just looking at dark home screen. HTC hasn't even figure this out yet??

no battery issues here
No battery issues, with slightly higher than average use (downloading loads of apps, playing some games, using google maps and a half hour driving nav and some music lsitening) over the first few days I've averaged 24-36 hours which I'm pretty happy with.
There are a few software things I don't like though
First, I miss having settings in the notification tray, it's one less tap of the screen. Also, the tweaked recent apps list seems pointless, you have to flick from one to another... the Stock android 4 recent apps scroll is much better, it let's you see/do more with less interaction. I also noticed a bug where the wireless signal will appear as null in the notification bar but if you view the the details in settings it says that the wireless signal strength is excellent!
Don't let any of this put you off though it really is a great phone and feels great in the hand... CM9 may rescue all!
Have the One S now, arrived a short while ago. The most annoying thing is that a stock device only has 9GB of that 16GB free when you get it.
This is nuts, I will not be using dropbox, there are many nefarious reasons why HTC want people to use dropbox or any cloud storage, this does not work well while I am roaming folks. This is not good for a business phone, I maybe sticking with my DesireHD.
Its sad, that many ppl who consider themselves technophiles do not even understand the battery of their devices.
ANY device with a modern battery should be initially charged overnight or 7-8hrs at least even of the little green light tells you it is all OK after 4 hrs. Do that, and give it a week to break in and I assume there won't be anything to complain about anymore.
Somy link to a decent site discussing these battery care tips and characteristics should be auto-pinned to each new device subforum cause the first complaints are ALWAYS about the battery life it seems...
So I did a fairly generic search trying to find out tips on storing batteries since I plan to get backup batteries for my phone, one of which will remain in storage for a while and I read that apparently under best charging practices it's actually considered to be high voltage for it to go to 4.1V and shouldn't go above 4.2V. Well, according to Android Assistant my battery charges up to around 4.33 to 4.34 or so (there seems to be some variance within that range.) Even allowing for the possibility that it's not 100% accurate this sounds like it's absolute torture on the battery. At the same time, it's also best to keep the battery charges short and small rather than letting it just sit and largely discharge frequently (and if I could help it I'd rather keep it plugged in and run as little from the battery as possible when I'm actually at home.)
EDIT: Sorry, I forgot. I was meaning to link to the original article and somehow didn't paste the link: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
So what I'm wondering is if there might be some way to trick it into deciding that a full battery charge is, say, 4.1V or even 4V? (From what I can tell by that article, 4V sounds like it would be pretty close to ideal since it's still more than 90% of the current full charge so still has a lot of capacity, but should considerably increase the battery's total lifetime. Even so, 4.1V would be considered "nominal voltage" and still a much better overall lifetime compared to the 4.33-4.34V range I'm seeing now. Heck, even 4.2V should be safer than that...) The phone is rooted and I plan to keep it that way -- I'm not in any rush to update to Jelly Bean or anything so won't be doing any updates or anything until I'm absolutely sure I can root once I do -- so even if it's something that requires root access it would be fine. I see at least one tool to force the system to recalibrate by basically just deleting the current calibration info, but that only really ultimately affects the level indicator and any software that relies on it, not the actual charging. I'm not sure if ANYTHING can really change the actual charging mechanism since it sounds like that is done more via hardware than software, but smartphones are a heck of a lot smarter than, say, a stand-alone battery charger, so perhaps it is still possible?
*Bump* I guess. Hate to do it, but I'm really curious. It may be built into the battery, not the firmware or whatever now that I really think of it, but I'd like to at least ask and see rather than never knowing. I'm kind of concerned because I think one of my batteries is already getting worn out. I've gone out of my way to increase battery life -- even using apps like Greenify (kind of a smarter way of killing apps, it doesn't actually keep just killing stuff, but actually disables their autostarts along the way and it's smart enough to not kill whatever is currently active and to give them a few minutes before it does kill) and I've used another more advanced app to disable a lot of the autostarts of a lot of other apps (including a couple of system apps.) I also have SetCPU doing stuff like lowering the CPU nearly to the minimum (it struggles to even turn on the screen if it's at the minimum, so I believe I put the maximum on 512 or whatever) with the powersave and even the noop scheduler (it doesn't get any more power saving than that!) Data is off, though I have to keep wifi on (but again, minimal apps running so just about the only thing ever using WiFi at all is e-mail syncing since I need to not miss certain things) and GPS is off. I've tried to keep it from ever running terribly hot with only a minimal plastic (not silicone and I've eliminated the horrible Otterbox case I used to have that had so much insulation that the only heat escaping had to go out the glass which is already pretty high on the insulation scale) grip and I don't really do an excess amount of gaming (well, I'll admit to a ScummVM session or two, but for the most part I'd rather use my 3DS or something else) so while I won't claim the battery has never been hot, I think it has generally stayed at least very reasonable and far better than most, so I don't think temperature is responsible for the battery life decreasing. On the other hand, if I look at that information it kind of implies to me that the extreme overcharging probably reduces the lifetime of batteries that should make it to 1000+ charges down to around 250 or something ridiculous like that (well, I'm not doing the math on it, but you get the idea.)
Is there anything else to be done, or is it pretty much just all in the battery itself? I'm really kind of planning on making this phone last for years if I can (well, I am kind of wondering if I should consider something just a little bit smaller -- maybe 4.3" instead -- but at the same time I need something that can do some of the stuff this one can like the actually surprisingly good sound quality despite being the US model without the Wolfsen DAC, so I'm not really planning on getting rid of this phone any time soon. With its excellent hardware for the time and wonderful support from CyanogenMod, it should last for basically every bit as long as I want it to within reason.)
I am curious about the battery in the one x, and especially the habits of consumption.
I have been around the block with android development. I had a captivate before this, and managed to get great battery life out of that! That was much more simple however. Flash a rom, cycle the power, cycle, cycle, cycle. Then you're good to go.
I feel like the way that the one x deals with the battery is different, more advanced. Some bootloader level software that is untouched, like the hardware keys and whatnot.
My battery has been hit and miss to say the LEAST. I use BBS to take care of wakelocks, keep data and gps usage to a minimum (my regular use), and I charge my battery when the phone is dead up to 100%.
The back of my one x gets very very hot sometimes. This varies rom to rom. Started with stock sense ICS, took the OTA jelly update, now I am rooted, s-off, and on cyanogenmod 10.2 nightlies (which run insanely well btw). The issue is the same. It reacts the same, and is just as unpredictable. I have read about this, and know its a hardware issue, but I am still curious about it, as I have heard SO many different things. I am usually able to quickly curb the issue by turning on airplane mode, or turning my phone off (for a while, as rebooting doesnt seem to help).
In passing, I also read something about "HTC Charge Mode". I have read forum posts where people say things like "hold both volume keys and the power button for two minutes, this with re-calibrate the battery circuit." There are so many combinations of keys and timings that people talk about that I can't help but believe that it is all garbage.
The heating up is typically caused by camera usage, data (radio, I assume) usage, games (temple run 2, gyro), and sometimes even spotify (offline playlists). Wifi seems ok, not too much of a contributor. When I was on stock sense jellybean, I was able to fix a lot of the heating up by turning off "google location services".
The weirdest part is that if I feel the phone warming up, I can go into airplane mode like I said, and its fine. If I keep perpetuating it, however, it gets very, very hot. Hot enough, im sure, to melt soldered connections. I turn on airplane mode, and it doesnt get much better. This is when I have to turn it off. Sometimes it hurts my leg in my pocket if I absentmindedly leave data on.
So I want to know -
1) what is the deal with the battery on the one x
2) can I cycle the power like I could on my captivate?
3) if you know anything I don't about the heating up issue, please share
Thank you so much for reading! I look forward to the possible feedback!
TL;DR - please read the post! I'd really appreciate it!
One thing I do know is that after doing your initial few charge cycles when flashing a ROM, it's better to not actually let the battery level get too low before charging. I read an article by a battery scientist, he stated that continual full discharging of the battery will decrease the long term battery life. So, it's best to do top-up charges from ~40% to full charge. Obviously you can disregard this when doing your initial charge cycles.
Some of these phones heat up more than others. Having the phone in your pocket or any enclosed space for an extended period of time will encourage it to heat up. I can't remember the technical term, but it's a combination of there not being enough air flow around the device to facilitate its cooling down, and nowhere for the heat to go. So it just gets worse.
So knowing that, there are some steps you can take to mitigate the heat, even if only in a minor way.
