Hey, i have switched my Stock rom to the Energy rom (.sensity version). Phone was taken from recharger around 6:30 and around 15:30 energy has ended. 9 hours while on stock i could get more than 24. During these 9 hours wifi was turned off and backlight set to nearly minimum. I used 3G for around 3 hours and after that i turned it off using comm manager. Is it normal? How much can you get on energy rom? How can i control what applications are turned on and what applications are using internet connection? Maybe there is kind of gps turned on? And i am not sure if it comes to the email that downloads messages.
bumping the thread
I've had terrible battery life with Energy ROMs for the past year or so. Release after release, his ROM never improved and continued to add new but buggy software. The phone would end up warm even when in standby in my pocket or on my desk. It heats up even after resetting the phone and never interacting with it (ie. no apps are running). 3G and wifi are off and the radio and rilphone.dll match. I don't know what causes the phone to heat up but that heat production means the battery is getting drained.
I have happily ditched Energy in favor of Monfro ROM. The phone is now always at a nice ambient temperature, as it should be.
as above test other roms if you still draining battary life real fst then maybe its time to get a new battary. if thoses roms work fine then switch over to them.
also post in Energy roms thread for help.
I had the same problem with the battery life, but with me it was happening in the night, so one time i woke up in night my phone was extremly hot and it had lost 20% battery since 3 hours before.
By that time i used TAEL Rom, I thought it might be the ROM, so i changed it a few times using Energy and other popular roms, but the problem still accured.
Then i change my radio and the problem was gone.
Could be that you have the same problem, but you have to try different things. It could be the ROM it could be the Radio, or it could be your battery.
I would have to agree with LtGenHartman that changing the radio may help or solve an issue. If you have an unbranded and unlocked version of HTC Touch Pro then i would say to find the appropriate radio and flash it (but keep in mind that you can brick your device rendering it useless).
My device is a branded HTC Touch Pro (aka HTC Fuze from AT&T), and since the device is not unlocked I will brick my device for sure. The battery draining is coming from two areas:
1)WM 6.5 does suck up a little more battery life since there are more processes running in the background of the operating system. Devices that do run WM 6.5 natively may not have this issue since it is optimized to run on that particular device. Also, there maybe a larger capacity battery that a device is using so battery drain is no longer an issue.
2) HTC Sense UI does drain more battery. It is a combo of processes running in the background to run the UI. It is also that there are fancy animation like the weather and transitions. Try eliminating some tabs that you do not use (For me I eliminated Stocks, Twitter and Facebook). It will free up some RAM and it processes will decrease. This may indirectly affect the battery life. Try using the standard Windows Default aka Titanium UI to see if there is a difference.
For the actual battery, try draining the battery completely before giving your device a full, healthy charge before you go to bed. I notice a bit of a difference in my favor since I did that a few days ago. I read this will recalibrate the battery giving a more accurate discharge.
When you are not using the internet on your phone remember to switch off all the data radios (disconnect from the data network, switch off WiFi). I think its ok if your device is finding the 3G network but as long as you are not connected to it, no data is being constantly sent and received so the battery life should increase. Try also switching all your apps that do use the internet to a manual switch rather than auto updating.
Just remember the stock WM 6.1 ROM has less processes, TouchFlo3D has less animations and tabs to use and the ROM was optimized for your device. That is why you will be getting the best battery life results.
These are some tips for you to try out, let us know if this help any. I don't expect a massive increase in battery life but some does help and from my experience does go a long way.
Separate issue: I do notice that the battery reader is not as accurate either. I notice that if i reboot the device the battery meter decreases (for example, if i reboot a device with 65% life i notice after reboot it can go as low as 50%). Wondering why that is?

I just received my fuze for 2 weeks, but my talk time is really bad. I tried almost every radio available with matching rilphone.dll. I see its listed at least 5 hours talk time, but my battery drop like 15% battery with 20 mins talk time. that's with 3G off, data off. just Bluetooth and Phone on. I get about the similar battery life with all the radios.
Well , you can just turn the bluetooth off. I have the same problem when I using bluetooth headset .
I guess the CPU and touch screen takes a lot of power , I have to charge my raphael every day.
maybe you can buy a larger battery .
what other programs are you running? Running this like SPB mobile shell and TF3D are big battery drains. Also, keeping your other programs running in the background is bad for the batterylife. try turning off all programs that you're not using after you're done with them.
I do have SPB Mobile Shell running. does SPB Mobile Shell affect talk time battery life? because it drains about 2-3% the whole night when I sleep.
Bluetooth!
Same here, while using bluetooth, the battery drains like anything. I dont use bluetooth anymore. It sucks but cant help.
sorry for not replying after a while.
i have SPB MS3 and it doesnt really drain it too much (a little bit but not too much)
what rom/radio are you using? those can be very significant factors for battery drain
i dont got a problem with mine, im running XBMods Rhodium TF3D with the AT&T Leaked ROM, with radio 1.12.25.19 i get like 7 hours out of it, without TF3D i get like 8.5 hours, and the reason i have that much its because i keep the phone off as in the screen, and like also i dont do anything to it like txt while on the phone and also signal is also a role in battery life as well
I had bad battery performance with Stock AT&T ROM
Then I flashed the Energy ROM 2.0 two weeks back and now the battery performance is much better
Possible Solution
Battery life on my Fuze sucked so bad the first week I had it. I saw it drop 10 percent just by looking at it for 10 minutes. So i started to dig around here on these awesome forums and the solution was simple. Whether you use stock rom or custom rom. Just find a way to turn off 3g networking. There are a bunch of tricks to do it. One thing i noticed is that my area has barely noticable 3g coverage so i found the signal reception always 1 or 2 bars. When i disabled the 3g connection, i found my battery increased dramatically. You can see for yourself by using DrSigstat. With the 3g its using over 200mah constantly trying to acquire the weak signal. This uses the battery very quickly. With the 3g off I am using as of this message 53Mah which extends battery life immensely. I am only connected to edge checking email every 30 minutes and this phone is usable. If you need the speed you simply toggle the 3g back on. The 3g network drains battery quick disable it I know there are a bunch of CABS to do it and even add it to the Comm Manager. Hopefully this helps.
I had the same problem, but that all changed when I took the phone on a Tahoe trip. Since I was using Garmin, the phone was ON most of the time and about 2 or 3 times the battery completely drained -- the phone got switched off on those occasions. And I used Motorola car charger to charge the phone during that trip.
When I got home a couple of days later, all of a sudden, the battery holds up like anything. Now I can go on without charging for upto 3 days with moderate use of course, but I do have google calendar and contacts sync'd up using activesync, 3G is always on and email sync'd thru pop3. weather and stocks updated few times a day as well.
And soon after I flashed EnergyROM with latest radio and matching rilphone.dll and now I have to admit that its a totally different experience with this ROM and the battery holds really well as well.
So I think that draining the battery completely and charging it using Motorola charger helped and then the EneryROM has a part to play as well.
Like zalooa said above, if you are in a poor 3G coverage area, it's going to drain your battery a lot faster, so location matters as well.
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.

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.
Get a Blackberry Bold. My phone has been on for 2 days, sent around 150 texts, got in 150, I'm at 85%

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.
Check my sig....it tells you how to deal with Li-ion batteries...
battery stuff on my site
Check out chapter 17. I cover this pretty thoroughly.

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.

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.
I have a htc touch pro (sprint) and i love this phone, its amazing i love everything but the battery. It seems to last about 8 hours even when im not using it heavy. Is this normal (i hope not), or just maybe my battery? Any suggestions?
My Fuze lasts about that long in sleep mode too... Not sleep mode all day, I do use it to text and surf the web once in a while.
I think it's normal, but I don't know...
I'm on the Tael Sense ROM

when your done with the phone press the power button to lock the phoen this greatly improves battery life turn off wi-fi turn brightness down to half way and select display timeout to 10 second and display sleep to 30 seconds also dont have alot of programs running it the back ground when your done with them close them report back if it helps also do you have any apps or your e-mail that constantly use data? if so switch ti to update ever 15 minutes or more
do you have new battery.....? i have used one , so i have exact same problem...but i will try with new one...
also battery caalibration can help you..to improve performannce of battery.....
I also have the same problem ,can somebody doin something...
This is not normal, if you are on custom ROMs make sure you have installed a matching rilphone.dll (plenty of info on this via search)
Also battery calibation is a big concern after flashing custom roms, I always make sure my battery is 100% charged before flashing as from experience found calibration goes a bit off if you have battery partly charged between 50% to 100% & can be a pain to correct. Read Energys notes in any of his ROM threads on battery calibration.
Also on custom ROMs hard reseting after initial setup is good practice & recommended by most chefs.
Last option is you need new battery.

This thread is useless if you don't give us any more info. 1. Are you using a stock ROM or a custom one (cdma, since you have Sprint)? 2. What do you mean by '8 hours'? Do you mean that from 9-5, with the phone in standby, it fully drains the battery? Or do you mean 8 hours of uptime (the phone turned on, and using it)? If it's 8 hours of use, that's not terrible, depending on what you're doing. That's a current draw of 168 mA, which is about what I get if I'm listening to music on tcpmp. It's also about the same as having the screen set to 10 (full brightness) and just having it turned on.
If you want actual help for your situation instead of generalities, you need to supply the following info:
ROM
Lockscreen (custom or standard)
Processes running most of the time
Bluetooth on/off a lot of the time?
Wifi on a lot?
3G?
Schedule for syncing email and crap like that
Custom UI?
Do you use the accelerometer a lot?
You may be doing some things that will burn the battery, but there's no way for anyone to know if you don't tell us how you use the device. The easiest thing to do is get tbattery.exe and log your battery usage to find out what is killing it (if it really is burning too fast). There are also other similar apps out there.
I'm having the strangest problem with my HTC Evo...
I used to get over 22hrs of moderate use (rooted) and ever since flashing any ROM running Sense 3.0 my battery life is affected to the point I'm lucky to get 6 hours of use. It discharges 15% within the first 10 minutes after unplugging the charger and continues to discharge at an increased rate throughout the day.
I unrooted the phone and took it to Sprint to "test" and after 3 hours they gave me back the same exact phone claiming they had "updated" it and everything, including the battery, had tested perfectly fine.
I feel like they are giving me the run around because obviously something is wrong here.
Any ideas as to what is going on here?
Rooting doesn't improve battery life, never did. Think of rooting as gaining admin privileges to a Windows PC, for example.
I think you have a background process running that is taking up a lot of battery, check the Battery Use page or reboot the phone.
I know, but it shouldn't diminish it either. It does gives you a chance to see a potential increase by undervolting, underclocking, ect.
Anways, no background apps running. All display scaled down, GPS off, ect, ect.
I have no clue as to why this sudden decrease in life. And Sprint says the battery is testing "excellent" as is the phone. Obviously something is not right here. Feels like they are being lazy and trying to avoid giving me a replacement.
Evo is known for bad battery usage. Best thing for you to do is get a backup battery.
Lol. I know that too, I'm not new to the Evo. I work with phones, Evo included, on a daily basis at my place of employment.
I'm saying this same battery used to last over 22 hours with moderate use when the phone was rooted and underclocked. Now the phone drains the battery amost instantly.
I refuse to purchase an additional battery to combat a problem Sprint should be fixing. I paid over $500 for this phone and haven't even had it a whole year yet. Something else is going on here...
Sounds like a rom issue, not a hardware one. Those sense 3.0 features and eye candy come at a cost.
Yeah. Sense 3.0 is a battery hog. Try cm7 or something AOSP
ADR6300
yeah, one turne off and reboot, Battery Life TERRIBLE too, i'm lost 10% when reboot

It's ture ！
Have you tried an app that shows you battery usage over your running apps? May tell you which programs are stealing all the juice
!. Rooting does not have anything to do with battery life...well..not directly..it depends on your kernels, apps, phone settings, etc.
2. I agree, Sense 3.0 seems to drain your battery a bit more than previous Senses... well...you know what they say, beauty has its price..about the AOSPs, they have better battery live but they are not so pretty as the Senses...again...beauty has its price
If it helps the 'Live wallpapers' are known to eat battery, but what it could be is Wifi, if you leave it switched on all the time it may be connecting to open wifi networks without you realising and eating the battery.
Interestingly though, a whole day of use, some wifi a bit of camera and some calls on a wildfire with wifi on, didn't seem to drop the battery much and this is with a rooted phone.
you can try green power
Even though it may sound lame to some of you, the app Juice Defender has actually helped extending the life on battery quite nicely for me...
Another possible route might be to try different Radio/RIL combinations, some can also extend your battery life.
Not to forget, as someone posted previously things like live wallpapers or background process. Task Killers have been known to cause battery drain for instance.
Good luck in your quest for battery life!
Hans
if you go to battery use in settings, youd probably find out whats causing your battery drain
I896, Rooted, factory Gingerbread.
I have a Captivate and a Tab. Both Wifi only, no Sims, Airplane mode on, Bluetooth off. Machines are on but screen is off. The Tab looses 3% over the course of the morning and the Captivate looses 20%!
I'm running regular 'power user' type apps; Titanium Backup, Tasker, LauncherPro. If there are any apps notorious for secret batt consumption, let me know what to avoid.
Running SystemPanel Lite - I can't see any app that is taking up more CPU time than normal that would explain this kind of drain. The battery page shows a good proportion of battery use display and wifi. In one instance I used the Captivate so little that display showed less use than wifi. In the course of just checking phone power consumption, the display use percent way up, just like expected (Just to show that wifi was really doing almost nothing) and still I had lost more than 15% of battery over the time when the phone was supposedly idle, not connected to anything with the screen off. Some ghost is sucking the life out of my battery. Grrrr. What could it be?
I loose 30% in a night with wifi off, backlight set to absolute min and nothing runninng or syncing.
I don't get it. Any ideas? What do I try next?

His tab is running Android too.
If you don't have anything helpful (or knowledgeable) to say don't say anything.
Op, download watchdog from the market, (system panel is kinda ..meh.) and see if there us a rogue app munching battery.
You may consider flashing a ROM see if its just that firmware/kernel reacting to your phone.
Have you tried Juice Defender?
Also, check to make sure you don't have applications constantly running. What version of android are you running? Check in system settings -> status -> somewhere in here you can check the battery status and what applications are pulling the most juice ... From there if one application needs to be removed you can action it ...
Also try the "Battery Calibration" app in the market. It's free.

my captivate running cm7 STOCK will drain down to 20% from being idle for 12 hours
my battery will also drain 30% from 45 mins of wifi only use.
doesnt help him but thats my experience from my captivate
Menu -> Settings -> Wireless and Networking -> Wi-Fi settinngs -> Menu -> Advanced -> Wi-Fi sleep policy
Set it to when screen turns off.
We have to switch that every time we flash. I really wish it was default. Some ROMs also have background data control, but it's usually when wi-fi is on so it shouldn't be a problem.

You do know that cm7 doesn't have the proper hardware drivers from Samsung so the battery life is known to be HORRIBLE right? If not you should really read up on the ROM you're using
Flash any touchwiz ROM, especially a native I897 build and you will see a dramatic increase in battery life.

I'm on CM7 and am going on 27 hours with moderate usage.. Granted, I have the 1800 mah battery from the Sprint Galaxy S2

I've held off replying as I was trying a few things and figured I would report only once I was done.
I found and ran Battery Calibration, just before I read the post. Between that and turning Wifi sleep policy to off with screen off, I had a great weekend. I was getting a day and a half out of my phone, which considering the use, was very acceptable. I was getting about the same drain as my Tab. I had 1% battery drain after 4 hrs of screen off time. That seemed fine for me.
I got back to school where I teach and yesterday the phone drained as fast as it has before. Interestingly, it continued its rapid drain even after I left the school and went back home. So, it died at 4am this morning. I heard it shut down. The school has at least 4 routers, two of which have 5k access options. I know if I choose them, my laptop drains way faster. Is there a way to limit my wifi connection on the captivate and not use the faster 5k connection?
But, this still doesn't explain why, even after I leave the school, the Captivate continues to drain when it is 10ft from a single 100mb wifi router.
I'm almost ready to try a custom Rom, but not sure how that will affect my ability to use it as a phone, once I get my Sim activated. Still new to this all.
You think everyone running a custom ROM doesn't use the phone?
Shouldn't affect your ability to do anything...
The WiFi and cell radio do increase power on lower signal as we know, but that's not always the cause of drain. I remember times using Froyo when kswapd goes nuts for no reason, or trillian, email, twitter or some other app just starts using massive CPU. Many apps are probably never tested on a system that has no connection most of the time. That's where all the utilities come in handy to find the culpret. OSMonitor can help find CPU hogs. TiBu can freeze apps, or uninstall them temporarily. Juice Plotter can monitor drain over time (newer Androids have something like it built-in). It takes some time to find it, but newer versions of the OS make it easier and have less trouble.
Also the battery % is only estimated. I'd trust full to empty time rather than 90% to 80% time as 10% use since it's not really as linear as we think.
Not to point out the obvious, but it can be the battery itself that has the problem. They aren't exactly manufactured to NASA standards... well, maybe their standards lately, but the point is, sometimes the ghost you're chasing is staring you right in the face.
