Battery Power Poor. Any advise?

Hi.
I don't seem to last a day without recharging my battery (either by USB or Outlet).
I have some useful programs but I'm afraid to use them sometimes because my phone wont last the day.
On a regular day, without extreme program usage (WiFi, GPS, games etc), just regular phone calls (GSM not 3G), my battery power lasts maybe 18 hours.
If i used 1/4 of my installed programs moderetely, my battery power lasts for about 10-12 hours.
I would like your professional advise to better by battery life.
1. Would changing my ROM to a better modified one solve my issue?
2. Is there a backround process (that is not detected my my task manager) working that I should know about?
3. Are there any tweaks (non registry) that I can do to better the life?
4. Are there any registry fixes that can be done to better the life?
5. Do third party cabs (SPB etc.) drain the battery life even if they are idle?
6. Does letting my battery fully drain and then fully charging it over and over really help the overall battery life?
FYI: I have the OEM ROM, my phone had never been Hard reseted before
I have tried all sorts of things, but I cannot manage to get my phone to last more than a day.
I would really appreciate your advise.
Thanks.
P.S please dont tell me that you people go 2-3 days without charging (that would hurt my feelings )

my kaiser lasts about 10 hours if heavily used, I mean 3G internet always on, browsing with opera mini all while listening to MP3s..
With normal usage and 3G coverage (but classic talks, not video ones) it last al least 2 days..
that's strange

Hi,
i managed to have good power after alot of research and tweaks on this forum.
-disable 3g service
-make sure no application auto-enable wifi, make sure its off.
-make sure device is set lock all buttons
on normal days with just afew calls and very little surfing, i my battery life is the same as other non-pda phones!

What do you mean with locking all the buttons?

Would updating my RADIO help?

Default ROM sucks. The registry is setup completely ineffecient (like all M$ software) so eats capacity and battery.
Best thing to do is check the 'Kaiser upgrading' thread and compare the radio version you have with what's posted there and see if you could improver performance. I'm still on the original radio that it cam with, but trying multiple Rom's dramatically improved battery life. That and speed and performance. Their is much to gain, my friend.
I advise you read the articles about CID and SIM unlocking before attemting to flash anything.

Upgrade your radio to 1.27.12.17/32, turn off 3G and flash some clean ROM (like Q-Mobile - see in my signature )
My phone can survive now more than 3 days on normal usage. Before it could live 2-3 days max.

Maybe can you enable alimentation tweaks with KaiserTweak to begin ?

I dont think and fixes of those kind will do anything
I think what Maarten_0031 and gabriel31337 say is the obly way. I will reseach what kinda ROM best fits my need and let u know

I'm using Schap's and very happy with it...

On average, how long does your bettery last?

2 / 3 days... Some phone calls, wifi and 3G
Much better than the HTC ROM !

You spell correctly and keep to the topic

Just got my Kaiser yesterday. Left it to charge all night and removed it by 7:30 am. At 16:00, battery shows 14% left?!?!?!?
What the heck?
Did all the power tweaks from KaiserTweak.
Lets see how it goes without 3G and with the tweaks I did today.
ROM: 1.81.415.4 WWE
Radio 1.27.15.32
Protocol: 22.51.88.13H

it can't be stated enough how quickly your battery will die if you have your mailboxes checking for new mail 'as they come in' or 'every 5 minutes', etc. if you have important emails your expecting then turn it to those settings, but if you don't care if you get your mail only every hour then go that route - it makes a big difference in the battery life.. also make sure you have the disconnect option in kaiser tweak set on - i have mine set at disconnect after 2 minutes.. and finally, if you can get away with using edge then have your phone always set to edge and only set to 3g for web surfing - pulling down your text based email in edge and not 3g is usually a pretty negligible difference.
on a side note, i bought a 3000mAH battery for about $70.. it improves the battery life a decent amount, but the reality is is that if you use the GPS for 2-3 hours without having it plugged in while using the GPS then you can always expect the battery to be dead by the end of the day (or sooner).. if your going to use it as a GPS then have it plugged in..

its all about wifi...turn it off if not needed.

This has been discussed in many previous threads.
All the above are applicable and also get rid of any fancy today plugins that show data state (WiFi-phone) and battery condition as they are constantly running and polling the relevant devices.
You will see a VAST difference when you do that.

Diamond RAM Usage Percentage

Hi,
My Diamond RAM usage is normally if i just did a soft reset 53%> and if i used it and turn off the screen 60% or higher...
Is this normal because i see movies on youtube where some guy has 32% usage of the RAM...
If anyone is going to recommend me to get rid of the default ROM and get myself another one, i need one that is very clos tot the stock its ROM and i'd like to have it Dutch...

i'm using the diamond from telus mobility, my ram usage on boot hovers @ 30%... with multiple programs running, itll be like 40-43%

I saw that video too I can't believe it's so low, even with the fastest cleanest rom at best it would be ~45%. I wonder if it has anything to do with CDMA vs. GSM?

Are you sure he use a diamond ? and not a touch pro ? I think the pro have more RAM, I'm wrong ?

im running right now @ 35%... how is that so impossible? lol do u guys not believe me?

Mine is more about 70%...

mine is always about 60%...when I launch a program it's about 80%

Are you using touchflow3d MightyMike? That takes a lot!

I'm running latest official ROM and the usage hardly goes over 70% ever.
At startup its ranges from 49~53%. (including gsen and some battery meter in the startup)
It seems OK to me^^.
I'd be more concerned about the RAM storage space, which is a serious issue to me!
cheers

mine @ boot = 53 and then creeps up slowly, and also creeps up after using apps (still memory leaks? )

Thats strange im using the latest stock-ROM too, well i hope htc will bring a new update and takes the RAM usage down because hovering @ 60% or higher is just too much if you want to run a program..

Using TF3D?

My ram usage is about 53% on boot with tf3d and s2u2 running.
Try to disable phone dialer skin...ram usage is 45% at startup!!!!

Just tried without the dialer : 62% at boot with T3FD. In fact i was about at 70% with the dialer...
But i don't see how to reach 45% !!!!!!! seems impossible to me ! perhaps desactivating the 3G ?
Ciao
Fred

46% at boot with smartblock running at startup. touchFlo 3d is running too. Panosha ROM. Not bad

Yes guys, i am running TF3D... put it this way i have a lot of tweaks, BUT
i've hardresetted many times, and at STOCK rom base apps, no tweaks, i boot @ 30% memory usage right now i'm @ 37% with palringo, and msn running

someone give me a small program to take screenshots, and i'll take one for you guys!

This is my memory usage upon soft reset
---------------------------------------
I possibly think its a difference in ram between the gsm vs cdma model... sorry guys!

Mine is at 65% after boot and after a couple of min it goes to 70%+ And using the radio i get 80%

Most battery "friendly" ROM

I wonder which ROM can improve battery life for HD? I tried 6.1 Dutty's and 6.5 Miri's until now. I couldn't pass 2 days of normal use...
Other experiences you have?

Battery life is more dependent on the radio (rom) than on the CE rom, and most of the rom around dont have radio bundled with them. You should rather look for a good radio rom to go with whichever rom you chose.
bR

Just flash a lite rom from Onkolog or Barebone. That will do the trick.

I upgraded radio version to 1.13.25.24. will see what happens...
Which combination of ROMs and Radio versions you recommend?

very same question...

The best radio depends on your location and provider.
you have to test this yourself to see what's best for you.
There is a small thread over HERE that gives some tricks to increase battery life.
The biggest problem is actually Windows Mobile. My Nokia E71 can go for almost one week on one charge. While my Treo Pro can only do about 2 to 3 days with the same battery... (My Touch HD also gets around 2 days)

I use the program on this thread:
http://forum.xda-developers.com/showthread.php?t=507301
it stalls the processor when backlight off...gives me a few extra hours, this and duttys 3.3XT give me a good 3 days of usage (completely flat byt then though!!)
but that is without BT or WIFI being used, no game playing or music listening just maybe 20-30 mins of calls per day.
Everyones different so battery life will change for everybody

Will check that out! Thanks for the link.

Sorry, but that's totally wrong!
The radio can improve the battery life, but normally the difference isn't that big at all, whereas the ROM can make a huge difference!
Its not the ROM itself that makes the difference, but the applications that are included in the ROM. Some applications are known for decreasing the battery life, because they are polling too often or something like that (or are programmed in a bad way).

Thats simply not true. In order to make a fair comparision you have to consider that any Windows Mobile device has normally a big screen, an ARM processor with something about 200MHz and a lot of hardware built in.
Certainly Windows Mobile drains the battery more than other devices, because there are a lot of abstractions in order to make it working with all the devices around.
Comparing the HD to the Iphone is fair, and you'll see that the HD has a longer battery life as the Iphone, so Windows Mobile isn't that bad at all, its just now thought as a "normal" phone, but as an organizer with the possibility to run really much and great programs (simultaneously).

The biggest variable seems to me to be the use you make of the HD. I have had several ROMS and several Radio's flashed and they can all be good or bad, depending on what you do with them. Some easy wins are to turn off "Receive all incoming beams", don't use WiFi or GPS. Also I have a UK Three SIM which defaults to 2100mhz 3g signal. If I switch Auto band selection off and force GSM then I get much better battery life (like 50% more) but I can't use data (other than Activesync which seems to keep working) as Three block data connections through GSM in my area.
Of course Johnpatcher is right that several apps cooked into some ROMs come with a higher battery drain. I prefer his own Barbones, at least then I get to choose what apps are draining my battery!
I still rarely get through a day without needing to top up but the point of having the HD is to use it and usually it is possible to put some juice back into it one way or another.
If you really want to see what is happening Battlog is a great tool, sorry I don't have the link with me but search should turn it up. Set it to log and it will show you the current drain at your selected time interval together with the programs running and the state of the phone and networks at that time. Makes it easy to see what is eating the power.

I didn't say the only reason was WinMo. But I've tried numerous mobile device with different OS's and it's plain clear to me that WinMo is the biggest battery drainer around. Didn't test Android though

If you get that program, share it with us. I am curious what applications drains the battery fast...
The question is still up!
let's see what combination of ROMs and radio versions we have on our devices and for a normal use, how many days can perform ....

If you agree that radio improves battery life, then whats totally wrong here?.....as i tend to agree with you even in my original contribution, but a bad radio rom IS a more likely culprit, and badly made CE rom that for example "disables standby" or affects power management function is as well a possibility. the choice of a good rom and more importantly a good radio is very crucial.

As I already said look the Iphone. The battery life of the Iphone is worse than the one of the HD, while the Iphone runs its own OS.

I haven't noticed any difference in battery life by choosing an other radio. I have noticed some better reception, but all kinds of these results are very subjective. You can read up the radio thread, you'll find enough people saying "yes", others say "no", its just too subjective ...

Battlog
http://forum.xda-developers.com/showthread.php?t=444920
This is the thread. I have installed Battlog on my HD and it works fine, at least how I use it which is logging set at 10 second interval and logging to a file on SD which I then analyse in Excel (it is a csv file) on the desktop. I've attached the cab I use as there may be different versions but you would be best to read the thread.
Obviously, as with any other experiment, the trick is to vary just one thing at a time and observe the difference. What tends to happen is that a number of things change and you don't know which one actually made the difference.
Strictly for UK users I have noticed that O2 seems to give the best battery life for my usage pattern and Three the worst (this latter is not surprising as they use 3g whenever possible and 3g is more battery hungry). Of course different locations in the UK and different mixes of use will vary this.

I think a big question to pose is : how much time is your screen on?
The panel is the biggest battery drainer, when I play with my HD, i can see literally the battery go down in little time.
Other settings as 3g or gsm network use is also very important, or bt and wifi on.
Our HD is a little laptop, the same rules apply for battery usage.
Ciao
Olaf

My experience is, go for a complete STOCK ROM (including the stock radio) and your battery life is acceptable.

I use for the moment Duttys, 3.3 XT with the last Radio; without 3G (only GSM) and moderate use of WiFi and GPS it resist 3 days... it is better then stock ROM..

Hi power consumption with clean rom

Hello i recently bought an older xperia x1. The problem is that the battery is emty in really shor time (10 hours), so i bought a new one. But the problem is the same.
I tried Kovsky unoff rom, also official rom.
Also tried clean rom with nothing installed and no settings changed, also some power management apps for win mobile.
Everything is turned off, wifi, data connection...
abcPowermeter shows 150mA power consumption, also when display is off.
taskmanager shows only 5-10% CPU usage for gwes.exe, i think thats normal when rendering results from taskmanager and all other CPU is for idle process.
I dunno what to try to solve this problem. Any ideas ?

My guess is you are running an always active program (like an IM program) that is sucking juice.
You may want to do a clean install and run it for a couple of days. See if the problem is your hardware or if it is that some software is the cause.
My battery life has improved from about 11-12 hours to about 48 hours after removing Palringo from my startup folder.
Also you mentioned you tried a clean ROM with no installed programs. If you didn't install any and you consistently have short battery time you have a hardware issue. Do the hard-reset, flash, hard-reset to ensure a clean install. Use a good ROM and do not install any apps. If after 4 days you still have short battery life then either your battery is dying (or generic and bad quality) or you have a hardware fault.

i tried hard-reset, flash, hard-reset. No changes

150ma idle is quite high IMHO. I run a test before because someone question my roms' battery usage and it should be around 80ma idle. http://forum.xda-developers.com/showthread.php?p=4784976&highlight=battery#post4784976
1. load the same radio.
2. Install Homescreen ++
3. Follow the conditions I tested over that post and see what you got.
Make sure you are in an area with good GSM signal too. Bad signal could lead your phone use a lot more power.
BTW, I found FDC task manager may not report real CPU usage especially if problem with services.exe. Try Memmaid to read CPU usage.

That acbpowermeter is a cool app. I never realized the panel I was using used so much power, and I didn't think having wifi on would consume as much as it did. Right now I'm using the WM6.1 that came with my phone and using the SonyEricsson panel with wifi off, and I'm getting an average of 70-80mA with the display on. Is this a good number?
I was looking into flashing to a 6.5 rom. Would I be getting better or similar battery consumption than the 6.1? If not, I think I'd rather just stay on 6.1 and customize my today screen with some eye candy, etc.

@jackleung
tried your radio with your rom, power consumption is even bigger, than in stock rom

Which UI has the best battery life? Lets all contribute some data and find out :)

I ran a search on "which ui best battery life" and returned nothing so this is the purpose of this guy
Tried making a poll but perhaps that is an admin ability?
So start throwing some opinions out! I've been running cookies home and gtx cookies home a lot and under medium to heavy use I get 1-2 days worth of battery life. Let's keep our scaling system limited to days and the only other factors we'll include are 2.1/2.5, UI (cookies, gtx cookies, maxmanilla, 2.1 standard, 2.5 standard, etc.), and radio.
Let's also only use this thread for data collecting purposes I'm actually going to collect the data and make some graphs to see if there are any trends happening and share that info with the community.
Here's what I got: 2.5 Cookies Home Radio: 4.49.25.91 = 1.5 days use

You really can't accurately compare UI's that are from different roms... Besides I think it's obvious that Sense and TF3D 2.1 are the best for battery life and memory.

Sorry, but you are not going to get any sort of meaningful comparison unless you have the same usage of the phone between ROMs, e.g. the same number of calls, the same distance from the cell masts (being further away = uses more power), etc, etc.

Sense 2.1 kicks Sense 2.5's butt when talking about battery life. Hands down best battery life. Thats with the auto weather and facebook.

Rofl, compare the resource consumption of TF3D 2.1 to SPB Mobile Shell 3.5.3 build 9885. I average 4-6 megs of RAM usage with three home screens. I get 1-5 days depending on usage (5 when I'm doing stuff that's risky for the phone so I don't bring it ;-) ), but I also use HTC's bigger 2,150 mAH battery. It's the exact same one dougie tested in his battery investigation thread in the Rhodium Accessories forum (I sent him mine to test). It was the only battery to score 100% of rated capacity, and the only way I can kill it in less than a day is by using it as a wifi modem and either torrenting something huge or a very large FTP or HTTP download. Also, several hours of nonstop Garmin will kill it in under a day. But, with about an hour of calls, 100-250 sms, 30-60 minutes of GPS, an hour of wifi, 15-45 minutes of HSDPA, and using GSM/EDGE for everything unless I need to Internet away from WiFi or utilize google maps satellite view for offroad shenanigans I manage 2-3 days on my Tilt 2 with Energy 21905 Titanium, .77 telstra radio, and SPB mobile shell with all my other cabs besides Lumos and Bandswitch installed to microSD.
So yeah, check out dougie's thread. I don't even have to remove and reinsert the battery to utilize the capacity past 1,500 maH like I had to do with offbrand Wizard and Kaiser batteries. It's quite smooth, and the bigger back makes the phone easier to hold. It's still slick, but if you have big hands it makes you feel less likely to drop your phone.

not very clear about your content,which one is less battery drain? TF3D 2.1 or SPB Mobile Shell 3.5.3 build 9885?
Also you get 1-5 days usage? 5 days? this is bomb news.......

First of all,let me introduce several mainstream UIs:
+ Titanium (no Sense,no nothing): if you only use titanium,then your phone surely drains least battery,but with titanium,you just cannot organize your phone easily.
some people may install Today addin which allows you to put programs in the desktop,this addin should not cause any more battery drain I suppose.
+ Sense (formerly touchflo 3D): no idea about its battery drain,but i dont use it,because it's not a convenient program,you just cannot cutomize the desktop that much.
+ SPB Mobile Shell : this is the UI I use,without it,I just hate HTC Pro2,very customizable,as for its battery drain,I have not noticed because i dont have a comparison,my personal opinion is that it doesnt drain that much,I saw someone said Sense drains faster than SPB mobile shell.
Anyway I think bettery drain has something to do with your rom, I even created a thread about which roms are least bettery drain,the link:
http://forum.xda-developers.com/showthread.php?t=649466
+ WisBar Advance: tried several times,old verisons,newest versions,just cannot work right with HTC Pro2
+ FEWidgets Ultimate: doesnt seems to be fit for HTC Pro2
+ iPhoneToday: this is discovered by me recently,after using it,oh god,it's amazing with almost no battery drain, now it replaced SPB Mobile Shell which was my favorite UI.
PS: other UIs,some guys created XP or VISTA UI for Windows Mobile,but the designers dont seem very serious about it, there is no further devolopment about them,and I tried some of them,looked beautiful,but crappy in practical use.
Ageye is developing Infinity UI, I tried their beta or alpha version,seems very lite and promising,but it is still being developed. their official link:

Sorry, but you are not going to get any sort of meaningful comparison unless you have the same usage of the phone between ROMs, e.g. the same number of calls, the same distance from the cell masts (being further away = uses more power), etc, etc.

As steviewevie says, this is not possible. Another factor is which radio version you are using. And how your rom is configured. There are just to many variables.

not very clear about your content,which one is less battery drain? TF3D 2.1 or SPB Mobile Shell 3.5.3 build 9885?
Also you get 1-5 days usage? 5 days? this is bomb news.......

I was clear about the content, but maybe not to someone that is not a native English speaker. SPB uses fewer resources and in turn uses fewer mAH.

This is very difficult to compare between people - the useage of a phone is one of the biggest denominators of battery charge. So it is easier to compare a certain person with multiple ROMs, rather than different people with different ROMS. But even with the same ROM, different people will have different results. In my daily use of NRG ROM, I can go 3-4 days. That is including hourly updating of my weather (SBSH Pocket Weather), phone calls, and a little bit of internet - Bing or Google maps, primarily.
I believe based on my experience that the following items will affect the length a device charges:
1. Screen. When the screen backlight is on, it really uses current. I use the "automatic" backlight level, and set mine to 30 seconds screen off.
2. 3G use. In general, using the Internet is power consuming, but even when idle, it appears that 3G uses more energy. Many people turn off 3G to conserve battery.
3. There are some advanced tweaks that will enable power saving on the various devices. I use the advanced configuration tool (also included in NRG ROM) to perform these functions. These are found in the Advanced Configuration under "Power Management". I set them all to "enable". Another tweak is to download the HD2Tweaks program - it has a setting to automatically disconnect the internet connection after a certain time.
4. UI of the phone. I have found that basic WM 6.x "Titanium" is basically about as power friendly as it gets. Here is my order IMHO, from most power conserving to most power hungry:
- Titanium / WM 6.5. Keep in mind it depends on what the various Today modules are doing.
- SPB Pocket Plus
- SPB Mobile Shell
- Sense 2.1
- Sense 2.5 (I find this one in particular to be always turning on my internet, I suppose to update the weather tab).
Anyway, those are my .02, err, $$.

I don't automatically update jack sh*t, cruise on EDGE unless I actually need to Internet something with the quickness or RDC into a server, and I use Lumos to manage my backlight. I like it better than HTC's method, and it uses like 300kB of RAM so f*** it. I'm on Energy 21905 Titanium with SPB Mobile Shell, and for me to get 4 days I basically have to baby my phone. 5 days requires me having way too much fun to be bothered by the phone much, and I'm using a verifiable 2,150 mAH battery as opposed to 1500. I'm going to try the Advanced Config power save options right now, but I read somewhere a while back on XDA that some dude checked the "Make Power Best Life Times[sic]" box on some ROM and it actually degraded battery life. Here's to hoping schaps' power miser tweaks make a positive impact.

iPhoneToday is missed here. It has the best battery life other than Titanium.

+ iPhoneToday: this is discovered by me recently,after using it,oh god,it's amazing with almost no battery drain, now it replaced SPB Mobile Shell which was my favorite UI.

I use for the most time the old school windows 6.1 (6.5) homescreen with date, calendar, messaging, homescreen plu plus ui, wireless home plugin and some others. this "old" homescreen comes without any animations, you have all your informations and apps on one screen (I use traylaunch too for the apps). It is not spectacular but fast, neatly arranged, and less battery drain. Best for my on my touch pro 2 and on the HD2 also

I am using an ENERGY cooked rom (the opne with the minimal ram usage and better battery life), in Europe (Belgium), i use internet with 3G because i am connected to skypoe and MSN and my battery, which is a 1750 Mh Seido original last maximum 6 to 7 hours !!!
With the original HTC battery, it is a little bit less ...
Any idea which rom will help me have a better battery life ?

Turn down your brightness. Or stop using a data connection constantly. Otherwise there is no way to get better battery life.

More cpu usage + more ram usage (I think) takes more power. So the interface you're using will affect battery life. Sense 2.5 with Co0kie's Home Tab is probably the worst for battery life. Windows today screen (not even Titanium, the one before that) is probably the best battery life, but I would NEVER be able to use that
There's a post about battery life in FAQ in energy rom threads I think...

Merely leaving your data connection on does not drain your battery. Switching it on and off uses more battery than just letting it stay on. It only consumes more battery when it is actively transferring data. Even with push email it doesn't use the battery except for when it actually downloads a message. This is why you lose a lot of battery in spotty coverage areas and it's constantly attempting to reconnect.

I said, stop USING. I didnt say not to leave it on. It was meant as a reply to the post above mines.
The best way to save battery is turn Updates and ActiveSync off or set it to something like 60 minutes and manual updates for Facebook (if using Sense).

I use the wvga version of "HTC Home" on my TP2,
