battery woes :(

ok guys as advised by someone i fully drain my vodafone magic till it dies and then charge it to a 100%.
last night i did the same just before goin to sleep,when i woke up in the morning the battery was at 76% after about 8 hours.I just had 1 missed call,1 sms,1 tweet and 1 email.
How can the battery drain so fast for no work at all???
pls help......

Do you have alot of widgets running? What do you have switched on, Bluetooth,GPS,WiFi? How often do you have the "Data Synch" set for? All of these drain the battery, if they are all working at the same time it goes pretty quick.

Woa! For the battery to drain overnight to 76% is crazy. never had this problem with my magic. It actually last very long.
But 76% overnight most likely means your battery is faulty and or you are leaving gps,wifi,and have quite a few things running on the phone like ClintonH stated.
however if you have everything off, as well as the brightness set low. Then contact Vodafone and let them know your issue. they should replace your battery at a free cost.

I suggest people use their battery for a week or 2 to see better results with their battery life. I started having poor battery life with my magic but now I can last about 2 day before I recharge it again.
As other user mentioned, it also depend what you have on or running in the background when your phone is on standby. I suggest you use task manager applications to kill unnecessary applications that might be running.

thanks guys
nope i have gps bluetooth and wifi turned off
i turned the background data off from settings
will try gettin task manager and see if it makes a diff!
thanks once again

Yes, are you by any chance downloading apps? Sometimes they hang and the download stops / continues lots of times. And when they complete your trackball flashes white.

ok thank mate i'll keep note of that!

I read a quite interesting post in the vodafone forum.
A user complained about the battery life of his HTC Magic. Check the answer from Wayne_Vodafone:
The HTC Magic employs a battery that requires overcharging and topup charging. You must charge it as much and as often as possible. The more you charge the better the battery life becomes. So after a few charges you should see the benefit of this. Letting the charge drain out undoes this so try and charge as often as possible

It actually seems to work. At least for me, try it for yourself.

I have to charge my HT-03A every night if I do not want it to die the next day. I am assuming that is why HTC gives you two batteries, because the battery goes so fast. As long as you are able to carry that second battery around with you, and be able to charge it every night, I don't really see a problem. But for it to go from 100% to 76% overnight means you are running programs that you do not need to. I will add that I have Wi-Fi continuously on, and my Contacts and Calendar are continuously synchronized. With barely any use I am usually at around 50% by the end of the day.

Pretty interesting, and that was an official vodafone response? Why wouldn't HTC say that in the first place? Will give it a go anyway...

Yeah, was a official Vodafone Response.
For me: I've loaded mine over night this morning, now its 19:26 and it's still over 85%. I used it for some SMS, receive a MMS and some WLAN.

ok guys thank u so much for the responses,im gonna give it a go too!
im using taskiller and defi my battery life has improved cause i keep killin the apps im not using
about the flashing trackball.......it still happens...no notifications.....

You never want to drain a Lithium-Ion battery. NiCd batteries have memory, in which it's better to drain them. But not Li-Ion. They will die quicker if you do

ok thanks xantonin.....
i charged my phone to 100%,then made a call for 41 min,battery went to 91%.
went to sleep immediately after that,woke up in morning with 1 missed call and 1 sms,after 8 hours......battery at 70%......thats not right is it?

That could be right.
Depends on what's running.
Where are you checking for 100%?
If you are charging until the green light comes on - that's 90%. The phone takes longer to charge passed 90% than it does to charge up to 90%.
I charged to 99%, and drove around with the GPS on for a few hours (about 2) and came back at about 75%.
However some days, when I charge my phone over night (true 100%), I can listen to music on my way to work (40 mins) on my phone, play with it a bit at work, and 3 hours later it will say 94%.
So, the battery is very touchy it seems...
Try turning off 3G (It's still pretty fast on 2G, try it for a day)
And also make sure GPS is off. Keep your brightness no more than 30%, and make sure WiFi is off. Make sure you don't have any widgets that connect online either.
You should get good standby time

Use apndroid to save battery life
Download apndroid from the Market. Use it to turn off the cellular internet before you go to bed and whenever else you want to save battery life.

There's also an app called Spare Parts in the Market that could help you. As well as giving information about your battery status and battery health, you can also see stastics of your application usage and battery history. A very useful app!
Plus it also enables other features like enabling fancy animations for the keyboard and screen rotation.

If you longpress the red phone button you can also enable "airplane mode" disabling any radio. Which helps your battery life too.

[Sol] Maybe: Sdcard Powermanagement disabled gives me more batterylife

I have noticed one thing yesterday.
From the moment i had my Rhodium (2weeks ago) i installed advanced Config 3.3 on my Rhodium.
From the start i had the "SDcard power management" enabled.
Since then i had a terrible battery life, 20% loss in 3 hours so at the end of the day my battery was empty.
And did not blame the powermanagement of this.
Trying to locate the power loss i used acbPowermeter.
After two weeks i came till the conclusion that there was nothing which drains my battery.
True out the day i use my phone for just a couple off calls and sms messages.
3G is disabled because the poor reception.
Also auto weahter updates every 2 hours and my mail is also checked every 1 hour.
Bluetooth is always discoverble which does not effect battery drain more then bleutooth off.
Activesync is killed and Opera does realy close and used the nopushInternet tweak.
So after testing al these and more.
Even how much those apps uses de proc.
I had to try one more thing, disable the SDcard power management in Advanced Config 3.3.
And today that config change made me verry happy.
Normaly i start working at 5am and work till 3pm in that time the battery has lost 60% power.
And today i was supprised my Pro II had 91% power left.
So i just want to let you know that in my case the SDcard Power management f*****k up my batterylife.
Specs
HTC Touch Pro II
ROM-Vers: 1.19.404.1 (51489) NLD
ROM-Date: 06/22/09
Radio-Vers: 3.44.25.27
Engergy Info Tab says at 90% battery life:
Last fully charged
23:24 Thu 18aug 2009
Standby time:
18 hours and 40 minutes
Speak time:
1 hour and 4 minutes
Device Use:
5 hours and 4 minutes
I believe these specs aren't that bad because before i disabled the power management my battery would be emty in 16 hours.
So i hope that my findings will help you all.

Bluetooth is always discoverble which does not effect battery drain more then bleutooth off.

Are you sure about that?
in most devices bt in descovery mode drains the hell out of the battery!
I always have my BT ON only, because thats all you need once you devices have been paired.

Hey Faria,
First off all i still love your rom on my old wiza200.
Back ontopic:
As i found on the internet and my findings with the discoverble mode that it is not on all the time.
It only opens the BT pairing when a device want to pair.
After that it closes and acts as BT on mode.
BT does not sends it signal all the time.
But correct my if i am wrong
edit
If i may believe AcbPowerMeter the power drain with BT on and BT discoverble is nill and BT off against BT on is that it isn't a power drainer

ha.. you mean you have it in a timed descovery mode. if that is the case then it is correct.
if i m not mistaking bt on only, drains less than 1% in 24 hours of the battery.

I get 7 hours of battery life and I'm a heavy user. I already have that option disabled. I need to improve this battery!!!

incredible!! your results are great!! any other detailed report, to clarify things a bit?? it would be interesting to have some data to elaborate some statistics and see what we come up with
in your fisrt post, you mean that you achieved the written results at the cost of only 10% battery life, or have I misunderstood it all??? if it's correct, wow!! °_° you have a nuclear battery! from 100% (and powermanagement enabled) I usually achieve 24 to 26 standby hours, 30min calls, 5 hours device usage (most of them connected on 3g). no bt nor auto connections of any kind.
thinking about it, it sounds a bit strange though: the OS is basically the same since quite a long time, and so the management of sd power (I think). so why would it do good (if enabled) on many devices, and not on TP2, having on the contrary such a bad impact on battery life?? I hope my question is clear enough!
since I'm no expert or programmer, I'd really like to have a little explanation by someone who really knows how these things work!
thanks a lot for the contribution, everything that may improve battery life even just a minute is super appreciated! best regards!

Nope my is discoverble the whole time.
About the 1% drain i am not sure, but after i am done with testing we will see how much it drains our battery.

I expect that my testing will be done with in two or three weeks.
Because i want to exclude every possible power drain and drain the battery till its empty to besure how long it takes.
Althought my battery isn't empty jet i will post some screens of the actual battery state.
And later this weekend when the battery is empty i will also post data of my findings.
With my tests i hope to save power and still be able to use the Pro II as its ment to be.
Or else it will be useless expansive plastic brick after 7hours of use time.
At this moment my battery has 43% power left.
And the last full charge was at 4am on 20-08-2009.
So its standby for a little over 54 hours. (current time 11:30am)
In my attached screen it say standby time 49 hours.
I do not know if this standby indication is the actual standby or what is left.
I mean that my Pro still has 49 hours to go.
Think there is a bug in de energy tab, but can not find anything on the NET.
This is what i have done the last 54 hours.
Why is tell you this? althought i am not an heavy user like many people here.
It maybe can help to compare my use with all you people.
- 4am 20-08-09: woke up and disconected my phone from the charger.
- 5am got to work, at work no provider connection so phone is searching for connection for little over 8 hours.
- 3pm got home, so now and then check the weather, play arround with new appz, had to put is some new appointments and contacts.
- Tryed some new reg tweaks, and took some pictures and make a short movie (1.39min) off the awefull weather over here.
- 10pm got to bed with 73% power left in my battery.
- Same story: 4am woke up and got to work to arrive at home at 3 pm.
- Did some checking on the weahter app, added a new contact, tryed some g-sensor games.
- And made two phone call about 10 minutes (not much for the last two days)
- Also send about 12 sms and 2 emails.
- Got to bed at 11pm and woke up at 10am with 43% power left in my battery.
- My mail is checked every two hours, no pushmail by the way
- I used the alarm function as my wake up call
I will let the battery drain completly and try some other possible power savers later this week.
And will post my findings over here including some findings i made with acbpowermeter and what effects background services or programms have on the battery.
At this moment i think i have charge my battery tomorrow morning if it does not shut it self off because of an empty battery over night.
If 4 days standby time is possible with little use then i'm not happy with the power drain.
Why: my wifes Omnia i900 is not used for over 3days (Backup phone at the moment) and has a been standby for 4,5 days and has 50% power left.
Okay i know i can not compare these two devices.
Because there different and we do not use the devices the same.
Later this weekend i will post what i have done and post some data and statistics.
And i will post which changes i made for my new tests week.
What i have done so far,
Energy settings:
-screenlight in battery power is full
-screen goes off after 1 minute
-device goes off after 2 minutes
Phone settings:
-band settings are set both to auto
Bluetooth:
-is set to discoverble
WiFi:
-Did not use it this test
Commanager
-Do not know whoe made it.
but is use the new commanger to quickly switch between 3G on or off.
Because in my area there is a poor reception of 3G
So currently 3G it is switched off
Advanced Config:
-sdcard powermanagment is disabled
-also the others mmc, nand, sim, async, pptp,l2pt
-Data connetions (gprs auto attach) disabled
-miscellaneous (auto daylight savings) disabled
Appz & tweaks
-manilla nopushinternet
-Opera wil close instead of minimize
-Activesync is killed by faking a server
-No2chem 1% battery bar
-Zuinigerijder TouchLockPro
-XDA-Developers GPRS 1 minute auto detechment
Rhodium settings tool:
-Auto rotation is off
-Power special tweak is switched off (next week testing it switched on)
So next week more data and background info

waiting to see the final results!!
btw, what is "power special trick"?? never heard of that.. sounds useful
the more minute of battery life we can obtain, the better!

how do you disable the sd card power management? i want to give this a try. also this is my first post and id like to say this site has alot of useful information!

any updates

I tried disabling and...well maybe there is some little improvement here, but I don't know if it's really because of this or if it's because of different patterns of usage during the days.. mine varies a lot.
as a raw comparison, it went from almost 60hrs standby and 5 of usage to almost 75 and 6 /6.5. both test with phone always on on 3g network, no data connections, no wifi, bt and such. just simple usage (documents reading, editing, tweaking, mostly PIM related tasks.
again, I'm not really sure it's power management related.. maybe V6Maniac did a more rigid comparison, mine's not worth it
waiting for updates
cheers

Palringo
Guys,
I am not a techie so dont flame me if what I say proves to be wrong.
When I installed cleanRAM and when went to the Customized Process List, I saw Palringo as one of the running processes. I remembered using Palringo on the day I installed it, but never after that, which is at least 10 days before. And it stayed there even after a day. Hence I decided to remove the installation and the process is gone now.
Now my batter is really good!!! I had a full charge by 6 pm yesterday and now it is holding at 84%. I did connect to Internet through WiFi for about 20 to 30 mins for skype call, updated weather and stock. Yet it is holding at 84%.
Let me observe it for few more days and let me come back to you if I find anything interesting.

it is known that certain programs are really nasty battery drainer. there's a recent thread somewhere reporting that a (maybe older( version of ESET mobile antivirus did the same. so we have another entry for the black list of abnormal battery drainer
thanks a lot!

Battery Drain HD2?

Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.

+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days

we really need extended battery ,hd1 battery was much more better.

Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87

I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.

I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.

try setting Network Selection to Manual

Same here with and without stock ROM.

yeah.. the phone is a battery sucker.... another cons of HD2....

This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.

I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?

maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse

I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy

Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.

Common sense Possible crappy battery fix

It probabbly seems ive been spamming the forum with alot of useless threads, but ive gone through many threads about some peoples battery only lasting a few hours, like mine, and others who last almoast two days! so anyway i was just wondering if anyone has just gone out and bought a new battery for there hd2 and the problem was fixed, as in the battery your phone shipped with was just a bad battery. i was just wondering all this before i went ahead and shed out a few bucks for a new battery,so incase the new battery dies at the same speed, i could save some money. thanks everyone!

stock rom- battery life is bad.. just barely making it through the day...
custom rom- people claiming battery life lasting "2 days" which i say is an overexaggeration...
and if you are just talking about accessories.. like batteries....well there is no bigger battery for us.. unless you want to get the extended battery.. which makes you hd2 fat....
now i'm still upset at the fact that the Evo comes shipped with a 1500 Mh battery... and that was modled after our HD2!! which means.... that technically.. there should be a 1500 Mh battery available for us....
but of course... there isn't... for some reason............. which does not make sense at all...... because regardless of the "Minor" differences between the Evo and HD2... they are both slim... almost identical in dimensions.... So the battery should be about the same size.... give or take..... man, i'd even buy a 1450 Mh battery... which would give me about 2 extra hours of battery life...
before anyone says it.. the batteries that are out right now.. are way too close to the stock capacity.. which would make my purchase worthless... I want to increrase my battery life.. not emulate it......
Also.. i do NOT want to keep an extra battery on me.. i do not have a purse... so i can't keep batteries on hand... thats just one big hassle....
and i DO NOT want to flash a custom rom.. stability and bug-free is the only way i like my phones.. i don't care if you never had to charge your battery ever again...... I'm sticking with stock..
so yea.. in other words... i'm just screwed........
love the phone though

Save Battery on HD2
TIPS
Besides the crappy battery that you might have it actually involves lots of things, such as ROM, Radio, Activesync etc...
- Running HTC Sense will drain your battery much more faster than running Titanium.
- Closing Unused apps that are running on the background from the task manager will help, dont use microsft direct push instead have it checked every 4hours or manual (that save A LOT of battery) also any other apps that connects to the internet automatically such as weather, twitter or facebook will drain your battery MUCH FASTER than usual.
- Hving he GPS enabled will drain your battery to ZERO In no time.
- I've came to realize that the Energy Rom's drain my battery soooooooo quick, So I stop Using energy's Rom's, I've also Notice that Duttys 2.11 base Rom with 2.09 Radio (Not the 2.13 base Rom) It has given me almost 2 full days (listening to music as well) so try out different roms and see whats best for you.
- Another thing You might wanna do is change your band from Automatic to Manual and go from manual H & 3G to Manual EDGE the times your not using the internet because if you simple choose automatic, since the Radio for getting the H, 3G, E, GPRS is located on the bottom of the phone (I made a thread about this) sometimes it will constantly jump from one to the other therefor wasting EVEN MORE battery that if it was just on 3G or E all the time.
- also you can try out this registry Mods I've been Using for the longest time (found them somewhere on XDA), I've use them on my WIZARD, EXCALIBUR, JUNO and they seem to do wonders with the battery:
1. HKLM\Comm\AsyncMac1\Parms\DisablePowerManagement
Change Dword value from 1 (default) to 0
2. HKLMComm\Irsir1\Parms\DisablePowerManagement
Change Dword value from 1 (default) to 0 i cant seem to find this on my dash or shadow
3. HKLM\Comm\PPTP1\Parms\DisablePowerManagement
Change Dword value from 1 (default) to 0
4. HKLM\Comm\L2TP1\Parms\DisablePowerManagement
Change Dword value from 1 (default) to 0
TIP 3
REGEDIT4
[HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Cl ass\SDMemory_Class]
"DisablePowerManagement" = dword : 00000000
(I've also attached the cab I have for the tweaks)
So Before Buying a New battery try this out and see if you Notice any difference.
Hope it Helps ​

That sums up how i feel!!! but personaly im fine about the capacity of my battery, its just that it goes down like 3% in 10 minutes, and this is when the screen is turned off! heres an example..... i charge my phone to 100% overnight , then in the morning at 7 i unplug it and get on the bus to go to school, on my way to school i listen to music the whole bus ride. when l finnaly arrive at around 7:20 , my battery is already down to like 87%!!! ive read on alot of forums about peoples batterys dying quickly like mine, and i have tried everything, so before i go out and purchase another battery i would like to know if it could be a battery or software problem....... BTW i agree with you on that extended battery looking ugly! lol

Alright i setup my phone for manual downloads and ran the cab (thanks btw!), and ive disabled gps, but im keeping sense running along with energy, i will post back on this when i get home from school, since right now it is 2:54 a.m. where i am. thanks for spending all that time for the tips! if the problem persists i will try running a diffrent rom, and then ill post back again! thanks again.

I usually carry a battery box like Sanyo mobile booster when traveling. I use 5000mah version it can charge you hd2 several times over and cost around 38USD in country where i lives. I prefer this over carrying a spare battery.

alright i got an update, so from 7 a.m. to 3 p.m. the battery drained down to 16% from 100% i guess thats not too bad considering i used it mildly , but still i think this is still too much drainage, i had airplane mode on, i had wifi off, and i used all the reg fixes and what not. so im gonna let it drain completly install that rom that you were talking about and see how stuff goes tommarow.

Wow, that is pretty bad. I'm normally on the go with mine from around 10am to 8pm, and use bluetooth, music, 3G, browsing, texting, a few games, and exchange/gmail/hotmail sync every 30mins. By the end of the day, the battery's usually around 50%. Have you tried different radios? they made a big difference for me.

I run Direct Push all day long starting at 7:30 AM... Right now it's 12:42AM the following day and I'm at 25% left. I don't do a lot of talking. Mostly email, texting, twitter, Internet with maybe 15 minutes total of talk time per day. I also end all tasks in the task manager before I put my phone down for any amount of time and leave wifi turned off unless I want to connect to a network.
I've found that if I'm in a location without a good signal that my battery drains a lot faster. Searching for a signal is taxing the battery... Lucky for me I'm always in really good 3G spots. House and office both have full 3G bars.
I'm running stock everything.
If I turn off direct push, I'll use like 25% over the course of like 15 hours... It lasts almost two full days...
When I get a new phone or any gadget with a lithium ion battery, I always make sure to drain the battery completely and fully recharge with the power off at least for the first two charges to condition it. It really does make the battery hold a charge for a longer period. Transformers is a good way to drain this phone... With my HD2 I let the battery drain completely twice with two "power off" full recharges. By completely drain, I mean, keep turning it back on until eventually it won't turn on at all...
I noticed with this phone that once the battery was completely drained, that I had to actually remove the battery and put it back in so that it would even charge... I thought that was weird, but no big deal... I'm also pretty good about letting it completely drain at least once during the week with a "phone off" full recharge...

Update: alright today after a full discharge and then a full charge overnight i ran the phone using kumars rom along with the 2.09 radio and the power saver on sbs tweaks and those reg edits that tuppacc gave me. today i left the wifi and the phone function on, and yesterday i didnt, anyway once again i used it mildly , but a little bit more then yesterday, so from 7 a.m. to 3 p.m. it went from 100% to 10% , which to me is still crappy, so i think im gonna go ahead and order a new battery and see if thats whats wrong.

To me that's good. I can barely get 4 hours from 100% to about 10%. Well that's because I use it non stop, surfing the web. Now during the night without touching it i get like 10% drained during 7-8 hours.

[Q] Battery Drain? And Opera memory problem?

Updated to the new TMO ROM (3.14 and the new radio too) a few days ago and I've been noticing that my battery is draining too quick for comfort. Maybe I'm just paranoid because it's a new ROM but does anyone else lose ~6-10% a hour (standby + occasional texting)? And when I go online (using Opera 10 with or without wifi) or make a phone call, it feels like ~30% per hour.
Am I expecting too much from the battery or is this not normal?
PS. I already did a hard reset a couple of times after flashing the new ROM + countless soft resets after reinstalling a few cabs (CHT, Duttys, CleanRAM, EndKey, and Opera 10).
Thanks!
PPS. While I'm here...sometimes when I close Opera 10 and run other programs and then try to reopen Opera I get this warning: ***Cannot open 'Opera10-armv4i' a critical component is either missing or cannot start because program memory is unavailable.*** Then it tells me to check task manager and close programs and start again. But I have no other programs running and I use CleanRAM and I still can't open Opera. The only way I can reopen it is via a soft reset...
Is that also common?

I'm at 44% battery and I've been using it moderately all day since 7AM... That's 12.5 hours... Not too bad for me.

Hey, I just got an HD2 [TMOUS] and I installed NRGZ28's Energy ROM for the phone. I am new to this forum, but I know the rules since i Have been residing mostly around the Developers forum and the Excalibur forum. in any case, I did a lot of research last night on how to get the best battery life. I AM using Sense [I know that eats battery], but I removed pretty much everything I can think of from the homescreen that uses data connection. I turned my E-Mail to Update only when I tell it to ... i removed the weather panel [heard it could use up more battery due to effects] ... removed the FB panel (i can just use the app) ... and the twitter panel... Then I did as other guides said and turned off the "My Location" feature. I also did some reg tweaks I had read do some real good for the battery, and so far I have yet to notice any difference than before I did all that.
My report is that I loose about the same as the OP ... roughly 10% per hour. I mean, okay, 10 hours of battery life is OKAY IF I WERE ACTIVELY USING THE PHONE. I lose 10% when just going through the phone, not running games or music, or viewing photos or videos. Just on Sense, going to the Settings panel alot , through the Start Menu, and the lockscreen occasionally.
First off: Is that normal? Is there are more energy efficient ROM? What can I do?
Secondly: I am aware of Extended Batteries, and I have researched some of these too ... I heard the 1600 mAh one that fits in the satandard casing actually doesn't do much ... then there is a 2400 mAh (?) which requires its own back-casing because it is larger. I got an extended battery along those lines for my Excalibur, and was satisfied with how it made it easier to hold ... but does the bulk make THIS phone look worse? It sort of worked for the appearance of the Exca, but I feel like on this phone it would just look like a giant tumor ... Any recommendations? Any good standard size, expanded life batteries?
Thank You so much [in advance]!

Your battery should be lasting longer than 10 hours. Mine lasts 12 or more hours with FB Data, Twitter Data, Push email and all of that with moderate usage. Mostly texts and emails, twitter and FB. Do you have your Automatically Adjust Backlight box checked and the other options checked under sounds & display in settings-->Backlight?

Indeed. My battery lasts at least 12 hours, most of the time 14ish hours before needing to be recharged. Haveing the system regulate the backlight is the single greatest thing you can do to conserve battery life, and alot of people have it tuned off for some crazy reason.

Hmm...I had read that I should turn off the backlight auto-control and install "AutoBacklightSteps" (or "AutoBacklight") ... That is what I have now at least ...
Right now I have brightness set to 20% [on battery], and higher on external power. Auto- is turned off. I use the app to change the backlight setting when I need to, although I often don't.
Now I don't personally use phones very very often. Seeing as I am in school, and one of the few kids who actually takes notes and doesn't text in class, I will use it for maybe 30 minutes at most [cumulatively] from 7AM to 3PM. Today, I used my phone as I think I normally would ....actually probably much less. In any case, it is now 10:33 here and I have 55% battery life. This is how I ran the phone for the day:
6AM : Took the phone off the charger [100%]
6AM -> 7:30AM : Phone left relatively un-touched. [98%]
7:30 AM -> 2:45 PM : the "Phone" [in comm manager] is off, in 'Airplane Mode' ... relatively low use [@ 2:45 -> 89%]
2:45 - 3:30 : I had 'Phone' on, received text messages I had gotten throughout the day, then turned it off [87% / 88% ... my memory is a bit fuzzy]
3:30 - Now : I generally had the 'phone' off, and I was in airplane mode. I intermittently turned it on.. I played some games, watched some moves [with Window Media Player] (I literally watched like 5 minutes of Transformers to show off to my friend haha, then I was done with that) Not much else...
All day the screen's brightness was at 20%. I used the LEDs for some flash photos, and the flashlight very rarely. I did take a couple of photos randomly thoughout the day ... but that was it. Right now, [after having the phone ON for about 30 min], my battery is at 55%.
I have to say that isn't too bad. Maybe the reader just wasn't that accurate yesterday, or I was doing a lot more than i though I was hehe [Could be file transfers and such]... In any case ... is this normal? I do expect to use the device more and more later on, I will text more and such [use Web sparingly as I know it eats battery] ... if I can manage to get though a day without losing power entirely I'll be happy haha.
Oh, and just some 'stats' : Today I placed 5 Phone Calls, received/sent 10 SMS, used internet for maybe 15 Minutes. That is basically it [since I know that probably affects seeing if battery consumption is normal].
PS: If you noticed I have the phone in Airplane mode a lot, it is because the signal for T-Mobile doesn't get into my school ... something about the dropped ceilings or just the architecture prevents the signal from entering, so I just generally leave it in airplane mode.
In any case, I would like to thank you guys a lot for already responding to my prior post
