Battery Life Stories

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.

[SOLUTION] Possible solution for heavy battery drainage.

My battery problem was becouse of the trancent class 6 8gb card(60-80ma in standby),
swaped with my friends verbatim class 4 8gb(5-10ma in standby)
even with my old sandisk 2gb non HC microSD(7-12ma in standby) I get better result than with my previous class 6 battery sucker.
App im using to test it is (currentwidget) from market, best app for testin battery drainage of roms.
If anyone else can post their results with currentwidget, wifi and data off, like this it would be great for all to know whats sucking all that sweet juice out of battery and will help development:
x MA standby
x WM ROM
x Radio
x Android ROM
x Kernel
x Micro SD
So my result:
5-10 MA standby
Chuckys GTX Lite
2.12.50.02_2
shubCRAFT 1.5
Default shubCRAFT 1.5 kernel
Verbatim class 4 8gb
UPDATE1
Another solution found by aussiebum that have worked for many is to disable or change keypad and notífication led drivers. Read post nr. 42 on page 5.
UPDATE2
Fix for random ~60ma(after boot) on standby if you had good results before. If you start Android don't use WM at all, use auto-boot on 6 sec with Exceller Multiple Build Loader for Android/Ubuntu if you want to use windows, use it but reboot the phone before you start android.
UPDATE3
So I have done lot's of testing with five different Micros SD card's.
And if someone still says SD is not related to battery I can insure you it's the biggest reason for battery drain, all these test is done with (shubCRAFT v1.5 origfonts) with new installation and absolutely same settings with SetCpu conservative 245 on screen off.
Ranking goes:
1. Kingston class 4 8gb (4-10ma stable)( As quick as class 6 transcend and doesn't effect battery drainage at all, My friend with nexus one gets about same results and its running from NAND, I'm perfectly happy with this card and wouldn't change it to anything else)
2. Verbatim class 4 8gb (8-13ma stable.)(I should say that this is middle card, bit faster and stabler than Sandisk Class2 but has bit higher drain of battery, it newer gets bellow 8ma, might luckily hit 7ma for few sec's. Still I would chose this over Sandisk Class2 because things was scrolling bit better and I think it's worth it compared to small difference in battery life)
3. Sandisk class 2 8gb (6-12ma)( Not stable sometimes it's at 30ma or 50ma when it's been on standby for long time. Is only little bit if not at all slower than Verbatim but still not as fast as Kingston or Transcend)
4. Transcend class 6 8gb (10-X ma)( Fast but unstable couldn't get it bellow 58ma in shubcraft, generally it's very fast and android runs well with no problems in load times, good but unstable battery usage newer got 40 min with 1% from any build)
5. Sandisk NON HC 2gb (9-15ma)( Slow can be used with android but not well thing gets stuck very often and load times are randomly crazy).

So my result ( at flight mode, using setcpu, no overclocking, no task killer) :
6 MA standby
energy cookie v2.5 08/28
2.12.50.02_2
mattc 1.7 sense build
Default mattc 1.7 kernel
Sandisk 4Gb, class 2

Removed task killer, after I pressed kill all button my MA went up to 130 for 5 min.
Think if it does that on every screen close.

energy cookie, newest
energy froyostone
2.12 radio
newest kernel
stock 16gb class 2 sd.
56mA on standby. i only let it run for a few mintues tho. ill keep it on and see what happens.
i have setcpu turn the cpu down to the lowest mhz on idle.. maybe ill test with that off as well.

hmm just installed current widget but a bit shocked to see 418mA displayed :O is that normal or what lol
ok nvm gone to 3mA now lol

Got ~60ma with HD2Froyo v2, 3g enabled, with widgets and setpu @ 245mhz on standby. Interestingly HD2Froyo v1 gave me 14ma with similar widgets, setcpu and 3g enabled. Trying to figure out why

Energy Cookie ROM (From late July)
Radio 2.12
Kernel: ElBartoME 2.6.32.9 #1
SHUBcraft 1.
16GB Class 2
I'm getting 60-62ma in standby, with data on and off (doesn't make a difference)
Right now Im not running SetCPU, Im going to try that to see if it brings it down.

After some poking around, I think I've figured out the cause of high battery drain during Standby / Screen off - at least for darkstone's HD2Froyo V2 Android build.
Battery drain seems to be caused by the libraries used to control and enable the led and keypad light to work.
READ UPDATED POST: http://forum.xda-developers.com/showpost.php?p=7949689&postcount=42
Current Widget now reports 7ma drain when screen off/standby, using SetCPU to set Interactive CPU Governor and 245-1113mhz scaling (8ma when using Conservative), versus 60+ma prior.
Downsides - led notification light is wonky, flashes green after boot (and goes away after awhile).
This "fix" should also work with other Android builds with battery drain problems (assuming those builds have led light working)... of course, check with Current Widget on your standby battery drain 1st (I do it by using 1min poll time and *waiting* at least 1min with screen off before checking!) to see if you have the same problem first.
If someone else could try this "fix" on their builds that would be great.
This was tested on a Euro HD2 running Miri v17 and Radio 2.09, with a Transcend Class 6 16gb sd card.
EDIT: Dropped some outdated info away from this fix.

Battery drain seems to be caused by the libraries used to control and enable the led and keypad light to work.
Deleting /system/lib/hw/lights.mahimahi.so and lights.qsd8k.so (both dated August), and renaming lights.mahimahi1.so and lights.qsd8k1.so to lights.mahimahi.so and lights.qsd8k.so, respectively in that folder and rebooting fixed my battery drain issue.
Current Widget now reports 11ma drain when screen off/standby, using SetCPU to set Interactive CPU Governor and 245-1113mhz scaling (8ma when using Conservative), versus 60+ma prior.
Downside now is that the keypad and led lights no longer work, but at least I'm not getting stupid battery drain.

The files might also be named differently on different builds though, so will need some experimenting.

Amazing. This works perfectly. I just went from 60ma standby to 5ma standby (neither with setcpu or a task killer)
See my post two up for my full settings, but I'm using shubcraft 1.5, in that directory the only one I found was lights.qsd8k.so. I renamed it to lights.qsd8k2.so and my battery drain went way down. The best part is the keypad lights and status led still work.

Yeah, I think there's a newer library build for controlling the led's which don't have the battery drain issues... Bangster's build comes to mind (as reported by someone else in this forum). Ditto with your build I guess.

glad to help. Spread the news and bug the chefs to update their light libraries with newer ones that don't have the battery drain problem!
I plan to try out the light libs from Bangsters (and probably mattc's) tonight.

Anyone having this problem?
When I go to sleep after 4 hours my screen is blank and the device doesn't turn on
if I don't remove the battery. After reboot currentwidget shows 250ma for 20min in log.
I had SOD before but this is just one huge SOD that has happened for me several times.

Simple Trick To Get 4-11ma In Standby

First, sorry for the new post on this, but I have not seen this mentioned. Didn't want it buried before it could help anyone.
I have used pretty much every android ROM out now, and for some strange reason they each have one constant.
ROMS which give 54-67ma on standby on first boot can be reset a couple of times until they reach the 4-11ma in standby point. Usually takes 1-3 resets.
Now, I'm not sure why this is all I know is it works. And yes, there is a huge amount of difference between 5+ and 50+ma.

I can surely confirm this

This is most definitely true, might sound illogical or fake but I personally took battery logs when my drain was 58mA but could not find anything, I changed Kernels just to observe the same and I finally gave up but I accidentally had to reset my phone a few times as I forgot to put it on charge/freeze then after a few days I happened to see terrific battery improvement 5-8mA, I didn't know why but then I understood it was because of the resets..

Good to see I'm not going crazy. Like I said, I tried this with a bunch of different ROMS. All the same.
So if you are having bat problems. Try a few resets and see how that works for you before giving up on the ROM.
Oh, I might also mention I am not running any sort of set cpu app.

Check again

Mattc Leo 1.8 with hastarins r7.6 with 5-7mA battery drain on Stand by (Wifi, GPS,Bluetooth off, data on(but disconnects sometimes))....

I can confirm this too.

Im a little new to Android on the HD2, running Mdeejay eVo Sense v. 2.3 rEVOlution 7.7 Hasteran at the moment.
Im finding the battery life on v2.3 less then on v.2.2 so I'll try a few resets & see if it improves, thanks.
Oh, is it really necessary to run SetCPU or a task killer?
Im forever closing tasks with task killer & the though of a task being auto closed when I turn the screen off is comforting, but is it best to just leave things to the kernal?

The most consistent way I have found to get 4-5ma on standby was to use exceller's android loader set autoboot android and 3 secs.

I can confirm this too.
I am trying dual boot (http://forum.xda-developers.com/showthread.php?t=723200) to boot into Android right away to see if that leads to more consistent standby battery drain. (this was mentioned on another thread.)
I have abandoned TaskKiller and AutoKiller, made no diff in battery drain for me.
I so still use SetCPU to slow the CPU when battery gets low.

For better battery life, setCPU is a MUST! Creating different profiles to change the cpu clock is huge in conserving battery; especially, the the screen off profile.
Ditch ATK and download Watchdog instead.

even hastarin himself is using android without setcpu. with kernels 7.6, 7.7 I get same batt juice as with setcpu, BUT less stuttering in general, i.e. android runs more smoothly.

Honestly I have found that every ROM I have used set cpu was a detriment to battery life.
I'm still not 100% that even task killer is helpful in some cases. I think that on the other hand has to do more with how you use your phone and what apps than anything. Some people can prob get away with it.

SetCPU is pretty much pointless now with the latest kernels, only thing it's useful for is overclocking, but even without it I've not found anything that can't run. Even graphically intensive games like Reckless Racing run perfectly fine at stock CPU speeds.
I've just updated last night to ShubCraft 2.0 DropMode and I get 6ma in standby, my battery dropped 9 percent in 8 hours of standby while I slept, and after a full day of using my phone from about 9am to 6pm tonight (texting, calls, wifi use, 3G use, picture taking, playing a few games and listening to over an hour of music) my battery only just hit 50% at 6pm. This is without SetCPU.

What i've done is just swap out the micro sd card for another one. I had the stock 16gb and replaced it with an 8gb micro sd card and i'm getting fantastic results.
Without any type of task killers or Set Cpu, i'm constantly getting 3ma - 9ma stand by readings from Current Widget.
I also downloaded Juice Plotter from the Market ( what a fantastic app IMO ) and it tells you how much time you have left on your battery as well as a graph detailing the percentage of power battery has used.
I can go a day to a day and a half with out charging my phone. I am in complete Android Heaven.
NOTE: Keep in mind that when booting into Android, when you hit the Haret, make sure that the hard key light are on.
I also have the auto sync off to save battery as well.

To get the 4-11 mA, just make sure the keypad lights on the phone are on when booting haret.(pretty much, boot asap)

After several reboots this is holding true.
Before when I making sure the keypad lights were on before booting Android I would still occasionally get bad standby drain, so I think that is myth.

Exceller's auto boot app = no battery drain!!!

GOLD!!!! PURE GOLD!!! Been trying to preach this for days now! The battery drain is eliminated by booting Android before WM/Sense fully boots. Has nothing to do with keypad lights being on or off. Hence, use Exceller's auto boot app set to boot 3 secs and restart your phone and let it auto boot. Battery drain ELIMINATED!!!!!

This is most definitely true, might sound illogical or fake but I personally took battery logs when my drain was 58mA but could not find anything, I changed Kernels just to observe the same and I finally gave up but I accidentally had to reset my phone a few times as I forgot to put it on charge/freeze then after a few days I happened to see terrific battery improvement 5-8mA, I didn't know why but then I understood it was because of the resets..

When you guys say do a few resets do you mean pull the battery or just use the off menu?

Just do a hot reset if your android buid has that option, even better power off and and reboot from windows

I'm using bangster v1.5 with hasterin 7.7. I only get 2-3 ma standby.
Sent from my HTC HD2 using XDA App

For me the problem was the SD card. I formatted it with 4098 (or similar)block size, copied the Android build back over the top and bang from 115-170mA to 4-9mA on standby!!! WOW.

Post your average battery drain on standby

I'm wondering if my battery drain on standby is normal so I want to know yours. I see some people with 4-5 mA drain and that makes me think whether my drain is on the excessive side.
batery drain: 11-12 mA. sometimes jumps to 130-200 mA, i wonder why?
What's on: background sync, 3g.
what's off: gps, wifi, auto-sync.
auto updating apps: yahoo mail
Please follow that format if possible. Thanks.

Your battery consumption is good, you will have around 5ma too by turning off 3g data. The 130 ma thing is due to automatic update somewhere. (mails, rss, facebook etc)

the only app that updates automatically is yahoo mail, i'm sure of that. so the jumps is a mistery to me. sometimes the jump is above 200 mA.

standby battery drain: 5-7 mA.
What's on: background sync, 3g, auto-sync, gps on but no apps using it, tasker, systempanel.
what's off: wifi, bluetooth.
auto updating apps: yahoo mail
if switch to 2g, standby battery drain can goes down to 3mA

-mine is playing at 10-13 mA on stanby. Now it is at 133-153mA while making this post.
Whats on: background sync, 2g
Whats off: gps, wifi, auto sync
Auto update app: yahoomail, yahoo messenger, gochat.
I have jumps sometimes but not as high as that.

I know this is noob-ish, although I consider myself somewhat seasoned, but what app (or other method) are you using to measure battery drain? I'm running shubcraft 2.0 over ChuckyROM and in standby all day won't last more than 11-12 hours. Ouch.
Thanks in advance.

CurrentWidget, free in the market.

Thanks so much!

My drain is mostly about 5mA. Sometime it is between 5-9mA.
I have nothing that sync automatically, but I have those jumps too. Mostly they're between 150-200mA. How often do they appear in your phones?
So, know whats on:
Data, GPS on but no apps using it, Systempanel, Facebook, Whatsapp
What's off:
WiFi (but the same standby if I'm using WiFi instead of 3G), bluetooth
In airplane mode it's only 2mA, sometimes 3

My drain averages about 5-7mA with the combo in my sig
3G on all the time (not a single data drop on over 3 days as well, best rom I've used), auto sync on for facebook and google contacts etc every 20 mins.

wow what else do you do? my phone jumps form around 134- 334 something with almost everything off

Mine is usually in 65-70ma range. There really is something wrong with it.
Are there any places to check for battery drain? I tried a blank data.img, which did not help. (I'm on HyperDroid 1.7).

4-8 ma in standby. i guess this is a good value!
wm rom: goatrip android 1.0
android build: mdj froyo revolution 2.3 with S7 test 3 kernel
radio rom: 2.12

my drain is between 2 and 5 mA in standby condition with background sync, 3g, data on. According with autoupdate scheme it's jumping to 135 mA
My configuration is as follow:
WinMo rom: VBNDroid-Reloaded2Alt-24634-Oct13
Radio: Radio_2_15_50_14
Android Kernel: hastarin 8.5
Android rom: [Everyday Builds][latest linux_on_wince_htc][PPP] CM6.1+
SetCpu: 245-1190MHz, Interactive governor plus screen off profile 245/245MHz powersave
My cpu is also undervolted: Hastarin CONFIG_HTCLEO_UNDERVOLT_800
My quadrant score is around 2000
No problem at the moment with this configuration. I have been running this for 2 days

- am, nothing. Just those and some of the usual apps current widget list as running in the background. I just use set cpu that's it.
Sent from my HTC HD2 using XDA App

Build - MCCM 3.3
Kernel - Hastarin 8.5
Radio - 2.10.50.26
WM - Cleanex OzRom
Between 4 and 5 mA in standby which equates to a loss of around 1% an hour. And with what I would call normal phone use I usually have around 30% charge left after a 16-17 hour day, sometimes a bit more, sometimes a bit less. I have stayed with an older radio because I have never had any issues so have seen little point in updating it.
I am more than happy with my battery life.

It's good that you didn't change. I think 2.10 is very stable. I'm using 2.14 and I think the standby was better with the older ones. But how much do you use your phone during the day? Mine is at 40% after 12 hours of moderate use. I think this should go better

What I would call a normal usage. On average around 5 phone calls totalling around 20-25 minutes, some wi-fi and data usage totalling around 30 minutes, some game playing and a lot of display usage as I read books using FBReader while commuting.
This is all guess work though if I'm honest, I have never measured exactly what I do with my phone each day because as long as I get through the day without it giving me low battery errors I'm happy. I would say I have been on 40% after 12 hours use quite a few times, that doesn't seem unusual to me.

My average battery drain is 3ma to 5ma
With wi-fi on 7ma

I'm seeing spikes upto 400 ma.
I assume this is because I am running the stock WM ROM?
I'm new to hd2 (from HTC legend).
Will using a custom WM ROM like chuckydroid get my battery running sweet ?
Gotta say hd2 is a dream !

Battery life with WP 7.5 / 7.8 - your thoughts?

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?
