Hello,
I have been following these forums for a couple months now, and wow I am impressed. I love this community. I feel like I haven't contributed yet, so I started this thread. Below are my phone specs and my battery success. If this helps you, great! If you can contribute to this thread with your success, please do. If a similar thread is around, let me know; I don't want to take up extra space if I don't need to. My primary goal is for people to share their specs, usage, and battery life with Android. I had my brightness on high and 3g, GPS, and sync on (things you would normally want on all day). Peace!
Specs:
Leo - T-Mobile version
SD - 16GB class 4 (not sure brand, doesn't say)
Radio - 2.12.50.02_2
ROM - 28/7/10 Elegancia V 1.0 Final, Max Sense (T-Mobile version, if there is a difference?)
Android- 03/08/10 shubCRAFT CM6RC2/Froyo/Themed V1.1
Kernel - Cotulla 2.6.32.9#103
Info:
Unplugged at 07:30 am with 100%
Immediately checked email/XDA app for any updates (yep, I'm lame)
Standby for about an hour
Music/web browsing on Train to work (30 min)
Standby for 3 hours
Video playback during break (20 min)
Standby for 5 hours
Music/web browsing on Train home (30 min)
Home for about 3 hours with mix of standby/web browsing
9:10 pm - 15% warning (close to 15 hrs)
I stopped at 15%, because that is my "safety zone" for normal usage.
Anyone else care to share similar stories?
Before sleep yesterday, i have 97% battery, but when i wake up today, the battery left 47% :S 6hours drain 50% battery life only in stanby!!
when i checked background for what was running, Nothing..... maybe the android's screen is off, just it's not really sleep..
Hey guys, it's totaly normal, the actual HD2-Android roms are RC's, these problems will get fixed, just be patient.
My battery expirience:
8:30 - took from charging at 97% and went to work
normal use @ work (sms, googletalk, twitter and facebook)
15:00 - 15% warning
its about half the time from my windows rom, i think at current state of development it ist totaly OK.
And if you use SetCPU you can get a 1% discharge per hour in standby mode, if set up correctly
And what Waldemotor said, it's still in development.
Powermanagment isn't fully functioning, yet.
patience young grasshopper
5:40pm 100% when leaving work, started listening to music
5:55pm Standby for train ride
6:45pm Listening to music
7pm: Stopped listening to music
7-10pm: bit of xda app, checking my ps3 friends to decide whether to play MW2, showed the kids a couple of games
10pm-7am: Standby
7:40am-7:55 - Music before train
7:55-8:45 - Standby
8:45-9am Music
And here I am 09:35 and I have 30% battery left.

I'm with Darkstone Froyo 1.1 and i sync:
Gmail (push)
Exchange Mail, Calendar Contacts) every hour
Facebook every 2h
Twitter every 2h
I use SetCpu set to 245/245 profile screen off and 998/245 standard profile
I also Use
Juice Defender (paid version from market) :
With this i can plan usage of WIFI/3G :
- U can choose from push up to 5mn every 2h, i don't plan
- U can disable during night my night is from 22h to 7h
- disable if battery under 15%
- enable when i use choosed application in a list form exmple email, browser ... (keep disable elsewhere)
- U can choose automatically enable when screen is ON i don't : i prefer enable with application
Note: it's possible to control CPU too but i don't .. i think setcpu is better
- Wifi may be auto disabled when there's no access point near u
Estrong Task manager
- With this i kill all application except a choosen list when screen is off
GPS is always Disabled
With theses applications and settings i can get:
0% lost during night
and during day, my battery life depends on how much i use applications with 3G or Wifi and ... over all how much i phone
Note :
I've same conf on my Htc Hero ... (Android 2.1 hect sense) my battery life is almost 3 days
With HD2 desire V5 results are not so good
So i recommend :
Darkstone Froyo 1.1 (waiting for next build)
Wirh SetCPU, Juicedefender (paid version on market), and Estrong task manager
JuiceDefender has a free version but wiyh less options but u can try it
U can control battery JuicePlotter : it draws a graph for ur battery consumption and temperature telling u if wifi or APN were enabled.
Hope my contribution will be useful for some people

Went to work with a full 100% battery, did a bit of webbrowsing and texting. It was down to 30% within about three hours.
But I'm not fussed. As it's been said, it's still in its infancy. I've done nothing to try and amend it (SetCPU etc). I just have everything running on default settings.
When things drop so far though, I just switch back to Windows if I'm not near a charger.
My 2 cents on the matter
I own an HD2 since last Friday, I think. I found out that it can run Android and I wanted to test it. I spent an entire day with the Android. I started with a full battery, but I browsed the market, installed a lot of applications, listened to some music, even played a few avi files. The battery is drained faster than on WinMobile, but just like it was pointed out here, Android is still in development. The main idea is that I used it a lot and the battery was almost drained in 9 hours (I also stop around 15% too). I used Darkstone Froyo 2.1 build (Dan1j3ls Froyo V1).
- zImage 3/8, Dan1j3ls Froyo V1 (without Sense)
- setCPU enabled (always ondemand between 245 - 998)
- Yesterday 7 am - unplugged with 100 %
- Sync enabled with 3G over the day, some web browsing and playing around all day, measuring
- *#*#4636#*#* -> Phone info -> Menu -> set frequency band to Euro band, afterwards the constant 2G/3G flapping disappeared, switch to 2G only happens, when no more 3G available
- 11:30 pm went to bed, disabled Data overnight -> 50% left.
- Woke up this morning 8 am with several alarms ringing -> still 41% battery left.
With little usage good two days possible!

I left mine at 98% before going to bed and 8 hours later (yes, I slept that long) there was 78% left...
I'm on MattC's build, German Vodafone Stock Rom (1.72...) and 2.10.._2 Radio.
SetCPU activ and Exchange checking for mails every hour...
However, I'm not sure if 20% or 2,5% per hour is good or bad
u can globally underclock ur cpu for better effect, I run mine at 80% clock (main profile)
Im now on my 3rd day of using mattc v1.4.
1st day battery life was SHOCKING (as to be 'expected' (can you expect a shock???) for a RC running off an SD card).
I probably got about 4 hours heavy use from 100% to 10%.
2nd day I set up SetCPU with profiles for 'screen off' and <25% battery, disabled all data except wifi, disabled gps (tried juice defender but didnt find it useful as I never really use mobile data anyways). LEFT SCREEN AT 100% BRIGHTNESS!
This ^^^ helped with battery drain a lot and stopped the huge drain i was getting while the phone/screen was asleep.
BUT on day 2 I got a WEIRD problem:
Tried to set a pattern for unlocking - Put phone to sleep and rewoke to test lock.
The screen came on almost all white with my home screen barely visible underneath the white 'vail'.
I shutdown android and booted into WM6.5.x.
THE WEIRD THING IS THAT BEFORE THE 'CRASH' MY BATTERY SHOWED 49% BUT AFTER A REBOOT IT SHOWED 14%!
Multiple restarts into winmo and android still showed 14%/13%! WTF? I had to start charging again from there.
Now the HD2 wont charge past 91% (in android), untested in WM. I unplugged the USB and replugged numerous times - still wouldnt charge past 91%.
Left on charge overnight (android) and still at 91 this morning.
Been using it quite heavily ~3 hrs on and ~1 in standby today with lots of wifi and batt has gone from 91 to 76%.
ONLY LOSING 0.5 PER HOUR in standby now.
So basically, my battery is going nuts lol.
But so far I'm more than happy with it (considering it running from sd etc etc).
To all devs working on android builds - THANK YOU and keep up the good work.
Anyone else had any battery anomolies like mine?
I also experienced wrong loading behaviour, or maybe it's just the percentage showing wrong.
The following helped for me: Reboot into Windows Mobile, there the battery loading status was display correctly as 100% (also with the status LED glowing green constantly). Then with loading cable still plugged in, boot Android, then in Android the percentage reading was correct again.
really offtopic but anyone care to share how do you choose what to run in the background and what not? I use the task killer app but I kill the apps and they just reapear without me starting them.
thanks for sharing brothers!
can anyone comment on the battery life/consumption with this latest kernal and 384+ RAM ?
im using zimage 08/03 right now with Darkstone froyo v1 and my battery life is pretttty bad...
it will go from "93%" (full, it wont charge over), to about 25% in 4.5 hours..
and this is making NO phone calls and on standby. I have setCPU with the settings from the other thread too
just trying to figure out a good solution
I'm using the CM6 froyo.
Without setcpu and without the Aug 3 zimage, my battery drain was about 12% an hour on standby.
Now, with the Aug3 zimage and setcpu, I have about 6% battery drain per hour on standby.
Win mo: stock Tmo-US ROM. 2.08 radio. (both stock). 16GB class 2 MicroSD.
I always make sure I charge when phone is either off, or in winmo. I never charge the battery on android. I don't yet trust the android kernel enough to charge my battery correctly.
5%/h in standby problem

Yes.
Not matter what I do, and whatever distribution I'm using there is huge battery drain in stanby mode (~5%/h). I changed ROM, radio, android version (mattc, darkstone, ...). Even used winmo registry tricks.
HD2 (eu), ROM Energy, checked mattc v1.5, shubCRAFT 1.3, NexusLeo v1, ...
But there was a time I had very good results - like 1%/h in standby. Do not know what changed (except changing Android ditribution very often). The other users (a lots of them) has 1-1,5%/h in standby mode, so I'm sure it is possible. There is some kind of setting/mistake or something to discover. For now Android (even running form SD) is capable to have as good "battery results" as winmo.
I will try
- charging in winmo only
- sd format or using another microsd card
- clean Android (without data and additional software)

same case for me as little usage (sync email few times a day manually, play few songs for kids, little browsing and market). 2 days with batteryminder. ~ 50% since last charged 1 day ago.
The one that making real different for me is when I used GSM auto (PRL) (in *#*#4636#*#*).
Also auto turn to airplane mode 11:30pm-7:00am for me.
I also applied the sdcard registry changes in winmo. seems this will take some effect also.

The solution was to
1. I did battery calibration (not sure this task was really necessery) and checked winmo battery drain - to make sure battery is not broken by Android. No, it didn't
2. Charge battery to fulll on WinMo (or turned phone off), boot Android then remove /data/system/batterystats.bin .
Use this commands from Android Terminal (free).
su
rm /data/system/batterystats.bin
Click to expand...
Click to collapse
3. Restart Android (in that moment I had expected 1%/h drain) and use battery till it come empty
Thats all.
Propably, after many android switches (new distribution tests) the battery stats was broken - collected partially in different Android version.
Then finally, after 1 week with 5%/h battery drain problem in standby I have 1%/h in standby again. I think it is standard drain in haret.exe version.
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.
I keep reading about this new improved battery life with Gingerbread, however I've found the opposite.
By the time I leave off work, my battery is typically at about 84%, that's with no usage all day. Today is the first time at work I've been running Gingerbread, I'm only half way through the day and my battery is already at 69%, if it keeps draining at this rate, it's going to be down to about 30-40% by the time I've left off!
Did you do a factory reset ? It helped me a lot, i'm at 4 days 6 hours with 16% battery remaining.
Also check if you aren't scanning for wifi 24/7.

Have you checked what application is draining the battery?
Google
I had dreadful battery life and discovered that Latitude was polling constantly and also Google Talk.
Make sure you sign out of both and see if it makes a difference.
... and disable "Tell HTC" service, it'll help as well.

Disable? with force close?
Right, I've disabled Tell HTC, signed out of Google Talk and made sure it doesn't sign in automatically. I've also signed out of Latitude.
The top four things listed on the battery usage are:
- Display = 34%
- Wi-Fi = 15%
- Android System = 13%
- Dialer = 13%
All others are pretty much under 10%.
I'd rather avoid doing a factory reset due to the amount of information and length of time it's taken me to get everything set up. However, I made the mistake of thinking that Wifi wouldn't be used if mobile network was on. My plan was that I would then connect straight away to Wifi when I was at home, and when it lost the signal it would switch to my mobile network. Well, this seems to work fine, however obviously as shown above, it's still using a fair bit of battery. I think I'll just start turned Wifi off completely until I'm going to use it.
For enabling/disabling wifi i use https://market.android.com/details?id=com.sas.inappwifitoggle . Long press search key and it gets enabled or disabled.
- Display = 44%
- Wi-Fi = 15%
- Android System = 23%
- Dialer = 23%
I use greenpower realy great app I'm running Gingerbread and I'm getting nearly 2days out of my DHD

Cool, looks like a handy program to have!
Check out this thread about the Dialer issue:
http://forum.xda-developers.com/showthread.php?t=1069251
My battery life hasn't improved either.
With moderate to heavy use I get about 6-7 hours only. My brightness is usually set at 30%
Display - 69%
Dialer - 8%
Cell standby and others - 4% and less
Is this normal?
Could you give us some more information here ? I mean what type of system are you using, Stock, or some type of ROM ?
I'm running LeeDroid's latest ROM, 2.3.3 and have Green Power installed so data gets turned off when my screen is off.
Auto-sync is turned off too.
In regards to mail, twitter syncing I set mine to every 6 - 12 hours.
I have had gingerbread RUU for 1 week now. With Froyo I used to get 15-30 hours depnding on wether I used 3g or Wifi(Wifi more conservative of battery). Since GB update my maximum battery lasts for 12 hours. I have noticed severe battery drain uder WiFi. Previously with 2.2 with the phoned switched off at night with Wifi enabled, the battery would drain approx 7% in 7 hours. Well today I did the same test switched off phone,left wifi enabled and the battery dropped from 90% to 46% in 7 hours which equates to 7% an hour with the screen off!
This is unacceptable! I sent HTC an email to expalin this but all I got was list of ways to reduce battery life such as swich off wifi, move to 2g, switth off live wallpaper etc etc. But all of this is absolutely of no use if the battery is draining at 7% an hour with the screen off. As I mentioned before with 2.2 the wifi drainage was small approx 1% with screen off.
Can someone suggest a solution?
1)Should I contact HTC again?
2)Try a custom ROM?
I havent tried a custom rom yet as the phone has been runnning well minus poor battery but I may have to if a solution cannot be found.

I noticed the same drain as well when I updated, but after a few days of testing I found that the problem was with one of my apps widgets. My guess is that the app is not efficient on gingerbread.
After removing the widget, everything was fine again.
To sum it up, check your apps.

when you say check your apps what are you using to find out whats running what.
Also how do i know what i can stop without making other things crash on me
for example. i do not use my sense account so can I shut dwn all things to do with sense that are running without risk?
I had the issue with battery life too. Just get the wifi switch on your homepage and turn off if you're not using it. Otherwise it constantly scans and leaches your battery.

Hi XDA!
I wonder if anyone is using WP 7.5/7.8 in productive daily environment, as my feeling is that battery life is really short. While fully charged and camera trick applied, i got a drop from 100 to 75% charge while using wifi for around 15 minutes (downloading apps).
With android installed as nativesd, i´m able to use it for max 2 days w/o charging.
What is your experience with these roms?
Thanks for your opinion!

Bit of a waste of a thread. Have your searched? First rule of XDA
Are you sure "camera trick applied" properly?
This battery usage seems a bit extreme with camera trick.
Also, maybe your battery is no good/old

Got Lumia 610 updated through NCS yesterday, while battery was fully charged.
Earlier, on WinMo 7.5, on a daily average use, the battery use to shell out at least 3-4 days of power with the mobile data connection enabled.
But, on 7.8, the battery drain is actually more, only after a day of use, the battery level dropped to 43% showing 19 hours of standby time.
That's just the stock ROM, from Nokia, haven't had any experience with custom ROMs.
Maybe the CNN application and Hike messenger are drawing on more power.
Thanks in advance.
advises for all WP7:
- turn off 3G, use E (2G)
- turn off BT and WiFi when not used
- increase or turn off mail checking time
- dont use (or reduce numbers) of Live tiles
- turn off background tasks in settings - applications - background tasks (after that you must manually update this applications but you lower battery consumption
also you can manually turn on Battery saver, go to "Settings - battery saver" and check "Turn on Battery Saver now, until next charge"... notice: with this apps wont work in background, emails not be received automatically...

Thanks dxdy. I yesterday installed pdaimatejam's "1_HD2 Pdaimatejam Rom Wp7.8 OS 7.10.8858.136 RMT v8.7" custom rom on nand. Battery used to drain very fast. Now did what you said and applied the camera trick too. Whatsapp running in background, with 2G, battery current after 2-3min idle is -19. Thats the lowest I can go. Before it was -178 at idle. So is it normal now ?
And I have not tried nand android ics rom. Do it have a better battery backup than nand wp7 ?

How much battery life are you getting now? I'm also having problems trying to squeeze out life of wp7.8 which is a shame seeing that the rom otherwise is completely functional.
Also what tool are you using to determine the current draw?
I tried to search but the results were not conclusive, so decided to start separate thread.
I installed NexusHD2-ICS-4.0.4-CM9-HWA V2.9a on an SD card to try it first, and I am running it from Windows Mobile through haret. Performance is good, everything seems to work fine, besides the battery life. It drains the battery in about 10% an hour. On Windows, it can last several days with the same type of usage, so it is not the battery.
Better battery stats does not show anything useful - it reports that the main consumption comes from the OS itself.
Nothing seems to alter that behavior significantly - I wiped and installed the ROM again, so that there are no applications of my own running. I turned off wifi, mobile data, and changed connection to 2G. That causes only minor variations in the battery drain. Played with the cpu governors - same thing, just minor improvements.
My device is T-Mobile HD2 with class 4 SD card. I used PPP when installing the build as the other setting did not work for me.
Has anybody experienced the same behavior? Do you think I will be better off if I put the ROM on NAND?

Try using NAND it does reduce battery usage by some percentage. But don't expect a big change in battery drain , it is common issue that we all are facing.
Battery should last about a day on normal usage. 10% per hour is a lot. Is your screen turned on? Screen takes most energy of all. Turn intensity down and let it turn to sleep in 30 secs or 1 minute.
Also, frequent battery checking drains battery too, so leave the phone alone
Don't use tools as juice defender, my opinion is they take more juice than they spare.
Sent from my NexusHD2 using xda app-developers app
and let the rom settle down for a day or so
becuase you cant really tell what the battery drain is after
a fresh rom install
Ok, if the range is around one day, then I do not think there is anything specific with my installation. It can be weaker battery or too much screen time. It was just too different than on win.
Thanks all

Battery drain will always be an issue as the battery really is too small for the phone. Have you tried setcpu or similar these cpu management programs seem to work to a degree in increasing battery life.
