X1 current consumption readings

I have my XPERIA for one week now and I am really impressed though I am kinda worried by its battery autonomy. Truth is that I play with it all the time and I had not the chance to understand how well it will perform on standby. Unfortunately all this week I am charging my unit at least once per day and hearing at reviews that on rigorous testing it lasted at around 2 days, got me worried (maybe I have a faulty unit).
Yesterday I was playing with AE Button Plus, (wonderful app) until I saw one option to bind a key to "Uptime information". In this screen you can find various information about battery status, voltage, when it was fully charged last time, total uptime, uptime forecast, etc.
The most surprising reading was "Current" in mA (milliAmperes). As soon as I saw it I started taking measurements on various occasions.
My results are as follow (all measurements in GSM and not 3G):
Idle with screen off ~50mA (not in standby just the screen turned off)
Idle with screen at lowest brightness ~80-100mA
Idle with screen at full brightness ~175-225mA
WiFi enabled +200mA
GPS enabled +150mA
GPS + WiFi + Full Brightness + CPU processing ~600mA
My device gets quite hot (not uncomfortably though) with WiFi and/or GPS and cpu usage, should I be worried?
Of course I can't possible know if the readings are correct but they seem weird, e.g SonyEricsson claims about 833 hours which is about 1.8mA per hour but in my readings it is nowhere near that. On the other hand 50mA in idling will last only 30 hours which again seems wrong.
In any case even if the measurements are skewed we can have a comparison between XPERIA devices and usage patterns. So what's your Current readings and/or battery autonomy?

Could you possibly do a test with GPRS/3G/HSDPA enabled by themselves? It'll be interesting to see what the measurement is compared to WiFi.

good job u doing here.. it will be good...
my X1 last at most 24hours on moderate usage.. this is bad

Hey Xavier,
I would say that your consumption readings are quite consistent with my X1. I used to have HORRIBLE battery life with it, however after many days of tweaking, I found 2 culprits that were causing my battery life to drop substantially, not letting me even get a full day out of it.
The 2 culprits are: S2U2 and FlexMail
- S2U2 used a fair bit of power, so I enabled SafeMode (set to "1") and that helped out big time. I don't think that SafeMode is a bad thing per say, as the only downside is that the clock will update once you turn the phone back on (i.e. it will 'jump' from the previous time to the current time, takes 2 seconds, no biggie at all)
- FlexMail was enabled to use IMAP IDLE. I'm sure this is the case with any IMAP IDLE e-mail client, as I've heard the same issue amoung iPhone users. It is also important to note that if you use FlexMail, each folder that you enable IDLE for will open and maintain it's OWN connection. Therefore, you should only enable IDLE on the folders that you REALLY need (I only have it on Inbox + Junk Mail). Again, this could be the case with every IMAP IDLE client.
To fix the FlexMail issue, I wrote a MortScript that runs all of the time and checks the current battery level, and whether or not FlexMail is running. If my battery is above 80%, FlexMail will run, however if the battery drops below 70%, the script will kill FlexMail, or not let it start until the battery reaches 80% again.
If anyone is interested, I can most likely release the script for download, as it can be tweaked to support any program/process.
Now my X1 will last about 2 days on standby, and my AEButton + Uptime counter actually shows that the device enters true standby. With FlexMail/S2U2 SafeMode = 0 running, it would never let the device sleep, and my Uptime was the same as when my phone was last soft reset (the counter just above).
If the phone is truly entering Standby (and not just turning off the screen), you'll notice that your Uptime counter is lower than when you last soft reset, proving that the phone really did enter standby.
Hope this info helps you guys out. Took me about 4 days of trial and tribulation to figure this out!

Thanks, at least this is reassuring for me that I don't have a faulty unit. Does your unit get warm to the hand whenever you use WiFi or GPS?
At some point I want to write my own application which will measure voltage and current and make a complete log of usage patterns, something like a battery benchmark utility (ala Rockbox).
I want to add that AE Button Plus Uptime information is a good way to monitor the charging current on the X1, many members report poor charging times with PC USB ports, with this utility you can be sure how much juice your X1 is receiving. The official charger from SE is rated at 750mA which is on par with AEB's measurements (around ~680mA for me). I also used a USB charger rated at 1000mA but I didn't got more current out of it compared to the official charger.

I have X1 from few day's.
Information about current power usage is great think in HTC powered devices (my previous device don't have it). I make little search for more effective use of it, and most usefull app's i found are:

Look most interesning, but crash when my device go sleep, i don't know is it don't like X1, or installed on my X1 as .cab .NET_CF3 - worth to mention, but as last position - UPDATE: after hard reset or on .NET CF3 cooked inside (not instaled as cab) work fine.
There are other tools for read power usage (like HomeScreen++ or mentioned before AE Button Plus), but this on the list monitor battery usage as they main function, and all are free.

You can try out also the program called: battery status. It has an option for powerdrain shown in the today screen. By the way the power consumption of my X1 in mA is similar to yours. See you at myphone.gr

~50mA at idling is strange. here is my readings with the same app:
94mAh with bright screen. Gps, wifi and bluetooth off and with full 3G reception
80mAh half bright screen
47mAh when I wake it up from standby directly after it has entered it
after a while in standby it will go down to ~18mAh
right now my battery is at 50% and the phone was fully charged 2 days and 3hours ago
wifi +200mAh seems to be correct though.

Hmm your readings are low. But lets clarify a bit:
94 mA with full brightness or moderate? (it would help to be specific) If in full brightness then I have quite a difference, maybe it has to do with you using 3G instead.
I get 80mA with lowest brightness.
We agree on ~47mA after standby. I must clarify that I got ~50mA just by turning the backlight, not by going completely on standby because I thought that in standby AEB stops monitoring correctly.
I must test more and see if I can get such a low reading
Thanks for sharing your measurements.

bah sorry for double posting...

Yup you are right indeed, AEB will still get readings and momentarily (just before the backlight skews the measurements) I got a reading of 20mA after standby.

I'm pretty concerned about my X1's battery life, comparing to what I read on forums and blogs about the X1, I have very poor battery life.
My phone lasts hardly a whole day after being charged on the wall charger the whole night, with only moderate use: ~10 mins of talking, 10-15 SMS-es, ~30 mins of wifi internet access, ~10 mins of BT, 20-30 mins of pics/videos and no GPS usage. When I used GPS, my battery went down from 100% to 50% after only 35-40 mins of usage... I'm afraid to even try listening to music cause my phone is probably gonna die extremely fast...
I have SPB Pocket Plus and Pocket Digital Clock installed and running on my today screen. I am also using the Yota phone dialer and contacts. For BT I have the hc4 ObexInbox addon.
In fdcSoft TaskMgr i noticed shell32.exe constantly using 0.8-2% CPU.
162 mA with backlight set to minimum
170 mA with backlight set to 20% (no auto-adjust) - all readings below are in combination with this setting
193 mA with wifi on and connected to AP
175 mA with BT on and not connected to anything
202 mA with BT+wifi
263 mA with GPS in use
90 mA just after waking the device from standby before the reading gets refreshed (this seems extremely high).
I hope someone has an idea why power consumption is so high and battery life so low, because currently my phone shut itself down before 20:00 every day, after disconnecting it from the charger at 06:00, and that is extremely bad (only 14 hours usage).

Does your unit gets warm to the hand if you leave it at idle and do nothing with it after some time? I had the exact same problem once. I would fully charge it just before I sleep and when I woke up it was down to 50%. When I touched it, it was warm and not metal cold like other times.
It was very hard for me to find the culprit, in the end I saw that G-Alarm was causing it (after setting an alarm). When I finally gave up using this program I never experienced the "warm after idle" effect. Other people will comment the same for other programs such as S2U and AEBplus (I haven't used the first and I am using AEBPlus since I bought my XPERIA and haven't seen this effect).
About battery readings, while on idle (power button) you can get readings as low as 18mAh. You have to start the AEBplus uptime screen then push the power button. Wait some minutes and the press the power button again. It should show momentarily a very low current usage.

I decided I'm gonna hard-reset my X1 today and then constantly monitor power consumption while restoring all the applications I am using currently, hoping I'll find the cause of the fast battery drain. If I don't find the cause and I've got a faulty unit I can screw myself cause I live in Croatia where consumer rights and warranty (especially for cell phones) practically don't exist...

Hi Guys,
I also had battery uptime problems.
For me on my X1 I can see the following:
- AE button plus is using a lot of battery on the X1 (I love this application and on my privious Kaiser no problems at all)
- Quick Menue
- Wktask
both have also a negative impact on the battery lifetime.
I am using now X1 Button (from this forum) to assign buttons.
With sk Tools I was changing the boot sequenze in the autostart folder and it was making a difference for me on my X1. At the moment I am making sure that the panelmanager is startin 1st and X1 Button is one of the last things I am starting.
In the beginnin I had only 20-40% battery left at the end of the day
At the moment I have 70-80% left at the end of the day for my avarage usage and of course this is different how much I am using the phone.
From my signature you can see the what rom I am using at the moment.
Maybe this is giving you some thoughts in what directions you have a look.
Best regards,
dingolino

For those that are worried about battery drain and are using AEButton and/or S2U2...
I used to get huge drain problems with both these apps installed with my battery only lasting about 13 hours with light to moderate usage, I uninstalled them and then could use my phone for about 4 days with mod to heavy moderate usage... I re installed AEButton but this time using 2.6.6 (was using 2.6.5 previously) and could still use the phone for about the same length of time similar usage... I then re installed S2U2 but used 1.45 (was previously using 1.37) and the battery still lasts considerably longer than previously, I have noticed no drop in the time it last actually... so if your battery seems to discharge quickly this could be a reason...

After hard-reset I finally get the expected battery life and I'm very happy
The only things I did not install this time are Yota Phone and G-Alarm, do one of those 2 is to blame for the high battery consumption. The phone lasted a day of moderate use and a day of little use (10 mins of talking, 6-7 SMS and 20 mins of wifi internet) and the battery is now at 70% which is great.
So, anyone having battery problems and using Yota and/or G-Alarm, one of the first steps is to remove those, it will probably fix the issue.
Thanks everyone for your help and suggestions

When I had the problem I was using YotaPhone too. It was a new program and I was very suspicious of it. After many tests I saw that this was not to blame. Even to this day I use YotaPhone with no battery problems. For me the culprit seems to be G-Alarm.

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.

Post best Setting for battery life

Yes.
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)

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.

Unhappy with your battery life? Fix is here!

Hi everyone,
I have had my Galaxy S for a month now, I have been very unhappy with my battery life, so I thought, I gotta to fix without compromising perfomance.
I found it!
My battery life during this 1 month period was utter crap, battery used drained from 100% in about 10-12 hours on average.
At the time I was running the latest FWs (I kept updating as the FWs came out) with Mimocans EXT4 fix.
I was with lowest brightness setting, running on 2G without any screen animations.
So heres the fix:
Install SetCPU 2.02, make sure to apply on boot, make the minimum speed 100mhz and the top 800mhz.
This ensures the phone doesn't ever go to 1ghz but that the performance is never compromised (even when playing games, videos, apps).
Because I have the Mimocans fix, everything is smooth and battery life goes down very slowly!
Heres the stats of my battery right now:
Battery Level 70%
21h 40m 25s secs since unplugged
Display 37%
Phone Idle 27%
Cell standby 21%
Voice calls 7%
Android System 4%
Internet 2%
Android OS 2%
You can give this guide a go, sorry if it doesn't work, just trying to help.

Azazin!

Please update with display time, phone idle time, standby time and voice call time. Without it these are a bit useless, these don't seem far from my stats when I use the display for +/- 1 hour.

I have the percentages up in the OP.
This guide isn't just for turning crap battery life to good, it's also for people to extend their battery life if they already have a decent one.
Following the underclock to 800mhz my phone can last this long, compared to before when it used to last 10-12 hours with same usage!

The percentages stand out, thanks, I saw them. Again, they are a bit meaningless without the time used. If you don't use your phone for 24 hours you should lose maybe 5% with sync off.
So, please, click on "display" and report the time that the display has been on, repeat for the other usage categories, other people will ask for this same information. I don't know if you didn't know how to do that or if you are witholding the information, hopefully it's just the former. I understand that, perhaps, you are doubling your battery life, but depending on the way we use our phones, relative to the way you use your phone we can see better or worse results. Doing this will allow us to know how much you use your phone and for what purpose, so we can make personal judgments about its merits to our usage.
TIA

This may fix the issue but it's merely a patch to cover up the wound. From my experiments I've found that in most cases the problems are related to the phone never entering sleep-mode. If you have bad battery life, please do the following:
0. Make sure you phone has been running on battery power for a while, usually a day with only 20% battery left is a good place.
1. Type *#*#4636#*#*
2. Go to Battery History
3. Other usage and "Since last unplugged"
4. Check the "Running" bar. Generally, if this is over 60% something is wrong.
5. Go to partial wake
6. Check if there's some application (e.g. Facebook) that has a high partial wake percentage. This is bad. System should be on top on most systems.
So, do you have the signs of something being wrong? Fear not! Usually this is due to a program or service misbehaving. I had bismal battery life (about 15 hours, just check the other thread for several of my posts), and then I uninstalled "Weather from Yr". I also let my phone discharge completely, then charge TURNED OFF over night. I then disabled auto brightness and "power saving" in the display. Yes, I disabled the power saving feature, and my battery life went sky high. Now I have about 2 days of moderate use (1h 30 min on) and about 1 day with heavy use. Letting any application run while the screen is off using partial wake KILLS my battery.
Unfortunatley, I didn't follow proper scientific approach when conducting my experiments, so I can't say which of the three things (uninstall weather from yr, complete discharge/charge cycle or turning off power saving) that did it for me, but it's worth a shot if you haven't rooted your phone. Post back with results.

Hi,
Oh okay lol, no problem.
Display: 1h 22m 8s.
Phone idle: 20h 51m 22s
Cell standby: 12h 12m 52s
It doesn't look like I have used it much but during the time the display has been on, I have either been:
Playing games,
Texting,
Twitter,
Or Internet.
It doesn't look like much, but I recommend you try this and post results before and after

2 things:
1) the phone number thing is pretty cool, in the past I've used "Spare Parts" for identical and a bit more information. I encourage people to use one or the other.
2) You can still fix the unscientific nature of your experiment by a factor of 1/3. You can turn power saving back on, and I'll try it. Also, I'll assume that 1 charge wouldn't make a world of difference, so I think that could've added a few minutes to your phone life (more than charging with the phone on) but maybe someone with actual technical knowledge can chime in.
As for any program running in the background, I had a similar situation where I was going from losing about 30% in a day, similar to the OP, while using the phone, and hence the display, for about an hour at work. I also, always preferred to leave the phone off the charger overnight, so I'd have been unplugged for 16+ hours. One day I allowed 3 things to run to check both battery and 3G usage (I have 500mb per month until I decide to change my plan, probably waiting for the new deal thats been announced for unlimited data for an extra 10 bucks sometime this month). So, I ran:
Sync
3G data monitor (To test if I would go over what I'd use too much data from my allotment, refresh every 30 mins IIRC)
ATK (to kill tasks, hoping they'd use less of my precious bandwidth)
This 2 tasks plus sync just CRUSHED my battery, by the first time I turned on the screen I saw more than 50% drain from my battery, probably around lunchtime (probably 3.5 hours from the start of work). I turned off all 3 and, like you, I haven't conducted a scientific experiment since.

I tried something similar with overclock widget, but I had the impression that underclocking made the SGS really unstable. It freezed completely like 3-4 times a day. After uninstalling overclockwidget the device didn't crash anymore.
So how are the longterm effects (say, 1 week) of setcpu?

If anything I'd OC my phone, not the other way around.

The software probably isn't optimized for your usage scenario, I don't think an underclock, if done right, should be that bad, OC on the other hand...

I'm in the same boat, screen uses 80%+ of battery when the screen is on, as long as I'm not wasting battery when the screen is off and processes aren't running I have excess battery life, not to mention a spare battery, which I'd like to get more use out of if I could better my experience.

crap battery life

[Q] Help, what is your battery drain, and why mine is sooo High???

First - let me state - and it is true - that I used the search function.
I read pages and pages of advices to lower battery consumption on my HD2 Android... without success...
First I used an SD ROM. I read that a NAND would improve battery life. So this is what I did.
I am also using SetCPU with a profile when battery <30% and another one when screen is off to LOWER the CPU speed. In normal use, I set CPU speed at 768MHz trying to lower power consumption...
I use a task killer to free memory and prevent silly programs to drain my battery off...
I use Juice Defender to control wifi, data, etc...
And with all of this in place, my "Current widget" shows a consumption of 180mA with screen on doing nothing, up to 350-400-500!!! mA when acutally using the phone wifi+sync...
In the forum I read consumption like 3 mA - 9 mA!!! This is FAAAAAR Way lower than what I ever had with different builds...
So this is an help scream to everybody: what is your battery drain, and why mine is sooo High???
Hint: I am also a fan of LCD Density changer, with setting at 165... can this have an influence on battery drain??? I reverted to the original 240, doesn't seem to have any influence...
Thanks for your help,
Looki

My drain is 3-9 ma in STANDBY ONLY now and again slightly more but mainly the values stated. And my screen on between 120+160ma. Turn off auto brightness if you have it on, and set it at the lowest your comfortable with (display is big batt drainer) I DONT use taskillers as they do more harm than good. I use NO undervolting and only the default settings with my rom. I have low lcd density setting 167 i think. Lcd density has no effect on your battery drain!
Found this here. http://forum.xda-developers.com/showpost.php?p=13151738&postcount=11296 Might be of some use to you? (from hyperdroid gbx thread)

Whats youre rom?
And do u use ext partition on sd?
I dont even use SetCpu anymore. Only taskkiller.
Auto-brightness is on
Auto sync is off.
Im using UD 3.3 nand from crawlingcity
Stansby is 3 -6 ma
Using round 160 to 250.

How long does your battery last from 100% to self shut down? As for Current Widget, keep in mind that when people say "Standby", its generally referring to the screen being off. Set current widget to update every 30 seconds, and turn the screen of for 40 seconds. Then quickly turn the screen on, unlock, and check what it is reading then.
If its still high, try "Force Stop" applications in the Settings > Applications menu one by one, i've had to do this more than once to locate problem apps that were destroying my battery in standby mode.

I'm knew to Android, let me share you my idea.
I use UD3.3
I removed google stuff
gmail, search, etc
No auto sync
Location off
Always kill market when screen off.
I use beautiful widget for weather manual refresh.
I use battery widget
Auto level for screen
sometimes WIFI on
2g Only
2 or 3 calls,total of 3 to 4 min a day
My battery stay 48 hrs in STBY mode.
I think the most draining factor is
1) google stuff they are battery hog.
2) screen
3) bad written programs (every time they check connection to
internet or looping for doing something, looping will make
CPU in high frequency).
4) bad device driver such as BT which is known as 60ma
drain. it is not the hardware but it is the software doing
the drain.
thanks

[Q] Dramatic battery drain (Hyperdroid 5.9.0)

Hi everyone,
I have used an older version of Hyperdroid over the past few month, which worked very well for me overall. Usually the battery managed to last a couple of days.
However, after I tried some different Android NAND Roms on my HD2 yesterday, I reinstalled the latest version of Hyperdroid (HyperDroid-CM7-Observant-Opossum v5.9.0) and noticed a dramatic increase in battery usage.
It drains about 10% in less than an hour without using it.
- WLAN off
- mobile data off
- Blutooth and GPS off
Androids battery use overview lists:
Display 35%
Cell-Standby - 33%
Idle 29%
Wi-Fi - 4%
There are barely any additional apps installed.

Install currentwidget and place a widget on your homescreen. Tell us the battery drain when the screen is off by setting the refresh interval to around 20, leaving the phone to settle in standby for a minute or so and unlocking it and giving the drain immediately displayed (don't wait for it to refresh again) and it should be around 4ma with everything but the phone function itself turned off. Try it in airplane mode as well, here it should be around 2ma. If you mean high drain with the screen on then you're just going to have to live with it unfortunately.

Yes i would definately check sleep drains. But if its when your phone is on, it may also be an update in the CPU governor settings. I would switch to conservative. Especially if you dont game a lot. You can also try changing your CPU voltage levels.

What's your kernel and governor? Any OC? Maybe the kernel isn't allowing deep sleep.

did you do a clean install?did you wipe your battery stats?
if you post some more info about your device then we can help you even more.
i would try changing the governor and then battery calibration (you can find it on the market). i had this rom and if i remember correctly there were some issues with my battery too. i then got the 5.10.0 version and everything became normal again.
or you can upgrade to the latest version 6.0.0. i just installed it runs smooth as hell!!!
good luck!

Even I'm using the same rom and the battery drains heavily only when using applications and playing games. But can anyone help me how to upgrade it to version 6.0 with detailed instructions.
