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.

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.

Battery drain and 3G

G'day everyone,
I'm wondering if anyone has experienced a similar issue to what I'm having on my x10i.
I use to unplug my device from the charger around 7am (100% - fully charged) and the battery dies around 7pm. The main usage of my device is for making a couple of short phone calls, sending/receiving tens of SMSs, regularly checking my facebook, twitter and email account. Not a heavy usage I think, around 85% of the time is put on standby. I was really unsatisfied because my other device "HTC hero" stays for over two days. A few facts about my HTC Hero: 1) It is way much older and nearly damaged, 2) I am using it mainly for family/personal really long calls (30-45mins per call) and 3) Always connected to my car's built in phone system (Bluetooth is up all the time).
Since I bought my device 2 months ago, I was in a continues contact with SE the Middle East regarding battery issues. Honestly, they were very informative and respond quicker than any other company I dealt with before. They replied to me with really useful tips that extended my batter life to stay alive till the mid night (extra 4-5 hrs). Tips given were: Brightness automatic adjustment, Disabling auto Wifi detection... etc. Though, I was still not quite satisfied.
One day I decided to do my own experiments to observe the real problem with my x10 battery. This was 3 days ago. The first thing I started with, and apparently the last, was disabling the 3G service. I turned off the 3G service, and turned on the 2G (Edge) instead. Believe it or not, the first day my device's battery status was about ~85% when I got back home from work, ~70% at the mid night, ~55 percent when I woke up the next day, ~25% when I got back home, and dies around 8pm (from 17hrs to 37hrs). It was a straight shock to me. I already know that enabling 3G would shorten the battery life for both the short and long term, but honestly I wasn't expecting this much of difference in the daily usage. The other thing, I didn't notice any huge difference between before and now. Internet surfing is a bit slower, couldn't notice the difference. Twitter, Facebook and email worked just the same since I check them whenever I got notified. The last thing is I'm using mobile messenger now, i.e. eBuddy, since the battery is giving me longer time, and all my messenger accounts are on all the time.
Please, if you are having the same issue, let me know because I was assuming that there's something wrong on my device, either on the battery itself or the build software (build # R2BA024)
Regards

The improvements you're seeing are probably due to you living in an area with poor 3G reception. The poorer the signal is, the harder the phone has to work to maintain the connection, thus, eating battery faster.
Although, it shouldn't be THAT big of a battery loss... I'd look at what programs you have installed and running and see if any of them are secretly eating battery behind your back.

You should try installing and running "Data on demand" It switches your data connection off when the phones screen is off...

Its well worth upgrading to 026, i saw a huge increase in battery life from that.

Absolutely correct. At home I can leave my X10 for days without it dying with 3G enabled. At work there are dead zones that'll suck a phone dry within an 8 hour shift though. It's almost always a coverage issue.
For any battery issue I suggest a factory reset and THEN make the appropriate adjustments. Sounds useless but sometimes you can emulate all the same settings and things still don't happen as anticipated.
Use a 3G toggle widget for long periods where you KNOW it won't be necessary. Root your X10 and add SetCPU to that bad boy. Screw using task killers because the Android OS is *nix based and handles memory just fine - I only kill tasks before putting my phone away when I know I won't use it for an hour or more. Other than that, don't use task killers, battery monitors or anything that'll keep your phone from sleeping. Use Spare Parts if you need help identifying an annoying program too.

Thanks all for the useful comments.
Now, I feel more confident that I can keep the battery alive for even more than 2 days. Thanks for your information and knowledge : )
[Q]: Is there any application that shows (in bars or digits) the strength of 3G signal?

[Q] Crazy high cell standby killing my battery life?

Help!
I'm running the 81xx firmware on a direct-from-dell unlocked Streak.
My battery life has so far been abysmal, and looking at the battery usage screen, my cell standby is usually over 60% while idle is less than 20%, everything else like 2%. This isn't from weak signal, though; I am in a well-covered 3g-only area and my phone has reported only being disconnected about 4% of the time.
Another strange thing is, my data indicator is constantly switching between the H symbol and the 3g symbol.
Anybody know what's going on?

It might be that while you are well covered for 3g, you are marginal for HSDPA and that constant switching back and forth is using your battery. I have not tried it but have a look and see if you can disable HSDPA in settings somewhere and see if that helps.

i'm usually around 40% cell standby.. do u have any task killer apps installed? although people think those are useful they usually do more harm then good.

I have the same problem, and I used another Android phone in the same location (hence same cell coverage) with no such problems. I just took my phone off the charger and had the display on since then non-stop. Cell standby used as much battery as the display!! There's no way that is appropriate.
I'm running build 8102, but it was the same with 6941 before. Can't tell about 1.6 as I bought my streak used with 6941 on it.
What Android version are you guys running? Maybe we can find common denominators.. :/
Edit: here's a screen shot of the battery usage after a while off the charger with the screen on constantly:

Do you think your antenna might be loose or defective?

I can't imagine the antenna to be loose really - but who knows, I bought mine used. If so, I think there is a signal strength value in " about phone" somewhere, no?
What signal strength are others getting? I'll post mine later, I'm on airplane mode right now so that I get some battery life.. :/

For signal strength, I am getting -75 to -95, and 9 to 12 for the two values while riding the train (not subway).
It also appears my battery life is quite good when my phone is in standby and not doing anything... the problem seems to come from net browsing or anything else that uses an active connection... Just browsng XDA is taking about 2% a minute!
Oh and my android is the 81xx 2.1 version with the modaco tweaks
Sent from my Dell Streak using XDA App

I had really high cell stand-by too. then i installed juicedefender, now my cell standby is down to about 29%.
I think the main thing is that it disables data connections while your screen is off and only turns it back on when the screen is on and unlocked. It also has a setting where it enables data connection periodically to allow background syncs and whatnot.
I'd recommend you guys give it a go, it had almost doubled my battery life!!

Mine shows,
cell stand by 50%
phone idle 44%
it seems quite common on the streak as I read in all the forums. I am on 2.1 stock rom? what's 1.6 like?

How is the battery life now?

I started messing about with the android builds when they first started to appear and the only thing that stopped me using it as a daily rom was the battery life.
I have been away from the forum for about a couple of months or so and was just wondering what the state of play is now with regards to battery life on the new roms?
Cheers

Well, mine lasts at least about one day and a half with moderate use.
With moderate use I mean making calls about 20 minutes, surfing the internet for about an hour, downloading apps, texting and gaming at least 1 or 2 hours.
When I get home in the evenings I have about 40% left.
My data connection is always enabled.
I never used apps like Juice Defender or something else.
I just have SetCPU und some profiles enabled. Nothing more.

I can get through the day with a decent amount of battery life. I listen to about 20 minutes of mp3's and check xda many times then stream pandora on the way home and I have about 57 percent left and I started my day 5:30am this morning and its now 3:19pm
Its my daily driver as I cant find a point where I need to panic and throw my reserve battery's in even though I have them just incase.
I use shubcraft 1.5 with setcpu settings and data always on.

Well I am still bashing my head against the wall when it comes to battery life. I've tried different builds, settings, registry changes and it just drains away.
Went to bed at 5.40am this morning (after falling asleep on the sofe ) with battery 100%, woke up at 8.45am and battery was down to 77%!
23% in 3hrs in stand by. It does my head in.
Like others its this that stops me from using daily builds.

Have you used current widget to see what your milli amps usage is during sleep mode.
Also are you using setcpu and setting profiles for screen off

I've gotten pretty good battery life 1.5-2 days with moderate use. I'm using Miri's elegancia WINMO rom + Shubcraft 1.5 + SetCPU. I noticed android drains tremedously less battery life on standby when Exceller Multiple Build Loader is used to launch Shubcraft by default set at 3 seconds. I use this setup daily and it drains even less battery then running the WINMO builds i've experienced.

All percents are per hour.
I drain about %1 in standby. (Usually 5-7mA in currentwidget)
I loose around %10 in normal usage when screen is on. (around 140mA with %40 backlight) If I turn on brightness to %100 and use wifi tether it goes up to around %20.
Standby current should never be above 10mA. If you get 60mA then you have high standby drain bug. Try new lights.so file or keep your gps turned of even if you don't use it.
New kernels with new builds don't have the 60mA bug even if you don't turn off gps, or don't keep the lights turned on while booting haret/android.
For people who have high drain:
-Try changing your sd card
-Use a newer evo based kernel/newer build
-update your lights.so file with a new version from gauner1986
-try booting android with keypad lights turned on while you launch haret.
-disable gps
User currentwidget to check your drain in 1 minute interval. Should be between 5-11 in standby. Must not be 60mA in standby.

I believe I have that bug. Only issue for me is this. There are times when I do run android and I draw 5ma in stand by mode, however whenever this is the case I get SOD. If my phone is drawing 60ma in standby mode my phone works just fine with no SOD. So for me its kind of a lose/lose situation. I'm not sure what to do.
My setup:
Miris GTX 2.5
chiasofts moomoo mattc evo 1.01
michyprimas evo r0 kernal

Mine used to draid about 60mA in standby, but updating my lights.so file and keeping the GPS off when I'm not using it bumps it dow to the 3-5mA range. This was the case at least when I used Shubcraft1.5. A lot of the newer kernels have the updated lights.so file already though

How do I update light.so ? may somebody post a link where to find it and how to install it?
I love Android on my HD2 but this Drain bug is reallx kinda annoying when you loose 9% per hour only in standby...

i've got sick usage too..
it drains in about 6 hours standby and 2 hours when screen is on..
i have NRGZ's 28 august energyrom with 2.07.50 radio and mattc's android.. i think i'm gonna update my android and hope it will be better..

I am using the Energy Cookie ROM with Froyostone 3.1 build and the new 2.15 radio. Only using 6-7mA in standby so no problem now to last a couple of days on light use. Call and signal quality is better for me vs. 2.14 radio using a TMOUS phone in the San Francisco Bay Area. It is also unlocked if that makes a difference. Seems to use much less than the standard WM OS. The Android 2.2 is my daily OS now.

A partial answer to the battery drain problem

I have been playing around with lots of Android builds in the last month but always ended up with a to high battery drain over time. Tried every tip in all of the threads but nothing seemed to help to get rid of a constant 50-60 mA drain when the phone was sleeping, got that disregarding which Android build I used and disregarding which WinMo Rom was underneath. This made Android practically unusable for me since i refuse to have to live with disabling everything (Wifi, BT, etc.) just to get a good enough battery life, it just kills usability.
After quite a chase I found the issue and more important the cure . Since i haven't come across this small detail in any of the other threads I think it is worth being shared.
The main reason for the drain in sleep mode is that Android likes to stay in touch with everything and has quite some communication going on which obviously causes Wifi to constantly suck the battery empty.
Go to Settings->Wi-Fi settings->Advanced Wi-Fi settings (you get these only by pressing the menu button on the phone) and change the WiFi sleep policy to 'After 15 minutes'). With this setting you should see the battery consumption in sleep decrease significantly without losing any comfort.....worked perfectly for me, the drain goes down to 3-5 mA as soon as the policy kicks in.
