1. having GPS and 4G on doesn't seem to have a very noticeable effect on battery drain when phone is idle. I typically lose about 1% every hour in idle no whether these features are on / off. I'm sure this would be different in an area without 4G... the radio would probably go bonkers trying to find a signal.
this is pretty good to know. not only do i love having instant access to these services, but it also allows programs like where's my droid to send gps coordinates back if the phone is lost.
2. a reboot usually takes 2% off my battery life. Once it took 4%! wth!
Haven't done any experiements with leaving wifi on yet but would be interested on others' experience.
oh some other basic info:
-running stock rom
-i use task killer set on manual to kill all the nonsense sprint crapware once at start up
-running push gmail
-turned off facebook, friendstream, favorites
-beautiful home widget updates q2h
Supposedly WiFi and GPS do not draw any power unless the app asks for it. The reason people still recommend to turn them off is that you might have an app in the background trying to use these services and drain the battery.

I can tell you that unless the battery stats app lies, this is not true. Wifi draws 2% or so on standby.
Interesting, is that 2% per hour? I keep meaning to do some extensive testing but currently I am only going off what I've been told.
Edit: Just a thought....You don't have it set to notify you in case of new access points do you?

If you don't set it to notify you then it doesn't auto reconnect to your existing hot spots. Also wifi is going to use power when it's on, but when you are connected to ask ap you are using less power than 3g.

Sorry about the question, it might be asking before
I have problem with the battery it can use only about 20 hours without use anything just data enable.
In battery use it appears Cell standby and phone idle drain battery up to 40% either, is it normally or my battery defected ?

That's about the same as I get on official O2 2.1 build. See my post discussing a couple of processes that seem to use more CPU than they ought. This does impact the battery quite significantly. As far as I know, SystemPanel is the only app that offers the monitoring functionality to enable us to check CPU usage.

Mine running official Froyo but battery still suck !
Sometime I've fully charged before go to bed and when i wake up it drain my battery 35% for 7 hours while I'm sleeping
Same here - around 40% down during the night...
The meter is kind of strange - it goes really easy down to around 40% and then slows down - yesterday i played around 1 hour with only 14% left...

This is exactly what SystemPanel will tell you. The lite version is free but won't give you the monitoring info. I highly recommend you get the full version and you'll be able to quickly determine what's consuming your resources.
I accidentally bought 2 spares if someone needs one cheap.

My batt was losing 17% an hour on IDLE on Steve's v1.4.6 !!! I dropped back down to the good ole default...now I only lose 2% an hour on idle.
...Also ordered a Mugen battery!!
I didn't used the dell streak before , but im using Samsung GT-I5503
I'm used to have the same problem and , the battery drained ridiculously and i dont even get a complete 12hours idle
then i figured out that there is an option in the (( Settings --> Wireless & Networks --> Mobile Networks )) called (( Enable Always-on mobile Data )) which is enabled and faded which I can't change it, and yesterday I removed my SIM card from the phone then i inserted another SIM card from another provider , I went to the same option and i found it enabled but not faded , so i removed the tick mark from it , put back my main SIM Card , and now the battery is running as expected which is more than 40 Hrs + per charge with normal use , and before I used to charge it twice a day with normal Wi-Fi use
Just to remind you , I'm using a Samsung Galaxy 5 GT-I5503 - Android 2.1

I don't have a data plan neither enabled Data connection before on my mobile , and i also deleted the access points from the phone just in-case it didn't use the mobile data connection because my providers are bastards and charge around 3 cents per KB
Anyway , what I'm trying to say is if the option (( Enable Always-on mobile Data )) enabled , it will try to use the connection device inside the phone as long as I'm not connected to a Wi-Fi , which will drain the battery more than normal , but when i had it disabled the battery life increased more than 5 hours
Are you having high battery drain with XXJVK firmware, or any other 2.2.1 firmware?
Does your Battery Use shows high CPU usage time on Android OS?
Then, check if you ever had Software Updates logged in! I noticed high battery usage once I logged in for OTA updates. Possibly, the device is retrying the connection to update server (which will always return timeout). You can see the Software Update service running all the time once you logged in.
If you have logged in Software Updates, go Settings->Applications->Manage Application->All->Software Update->Clear Data
Once you have logged out from Software Updates, the service disappears and personally, battery life doubled.
Thanks, i will try it!
It really could be the last chance to solve my idle-drain-prob.
i'll report back.
//edit: cleared data, service automatically stopped. i'll report back tomorrow if it solves my drain-thing.
Yup i had it running too since boot.. cleared data and will report back
Let's hope this is the answer. I've just took the drastic measure of doing a hard reset and now battery drain is pretty much zero and phone is idle when screen is off. I'll keep installing and enabling things and see what takes more battery.
Very interesting, I did check if there were any updates, and I suffered from random battery drain. At first I suspected Google Maps/Navigation, but you could be right. I started Maps, and Navigation, killed en cleared OTA, and I am monitoring the battery.
I have found that when i use the built in task manager to "clear memory" as soon as i have done that the battery drains alot faster and my android OS in battery stats goes through the roof (from 5% to something like 14%). It has been running fine since yesterday and i cleared memory only to find my battery went very quickly from 28% to 9%. I rebooted the device and all is well, i wont be using that option anymore
After installing jvk full I installed jve modem, rooted and did battery stats wipe and battery issues went away.
i lost 25% over night in airplane mode
background & sync = off.
after clearing dalvik cache & battery recalibration using battery calibrator from market i have 5-7% drain per night, and 30-40% per day... last battery time was 2d 19h 14m, with some calls, some games, some wi-fi and some hsdpa & with weather widget update every hour.
info
i9000 + JVK (repartition 512, with bootloader) + CF Root
P.S before clearing dalvik cache & battery recalibration with same use i have maximum battery life - 23h
Clear the data for "Samsung Account".

There's something very wrong with your phone, either your battery's shot or there's a rogue program draining it, you shouldn't lose more than 1-2% overnight in airplane mode.
Same problem here. I hate this device...
Is it just me that think battery life is much better than on froyo?

I have no battery drain since i upgraded to jvk.
Sent from my GT-I9000 using XDA App
I'm seeing huge battery drain like others, sometimes more that 50% in a few hours doing absolutely nothing, wifi & 3G off and OS takes up to 60% of the battery usage. I never activated Automatice Updates since I flashed JVK. I am now on Darky's v10RC3. Only a few people are having such problems, most users say they are experiencing their best battery life ever.
I noticed that this drain always happened to me after I used Maps / Navigation. So I suspect them to create problems, maybe kicking off Software Update in a bad way. And rebooting stops the drain (it once took as long as a full flash for my phone to reboot...?).
So I have bought for $1 this nice app called Autostarts that shows which apps autostart, what triggers them to start and it is then possible to disable by app / event.
When I tap on Software Update, I can see that it kicks in on these occasions:
- After Startup
- Application installed
- Application removed
- SMS received
- Secret code entered
I disabled everything as well as for Map, so now it's no longer showing in running apps / processes.
Will follow this thread !

Spot on.
My Android OS battery usage is down to 3-5%.
Great find guys, Thanks a lot!
Also, a little suggestion here but I need someone to confirm.
Regarding Google Maps, I was having some trouble getting rid of Hotpot and Rate Places processes as they were constantly running for no reason and restart after I kill them. Another 13% drain. So yesterday I updated to Maps 5.3 and the processes are no longer there even though I've used Maps, Hotpot and Places
I upgraded with odin, repartition and bootloaders. Since now the battery life is very good, i can see the difference by eyes.

This worked for me.
Im currently on XXJVS with Semaphore 1.7 kernel, but i have experienced the same behaviour the last weeks (or maybe i just started noticing recently): traveling starts a battery drain
Update: see post #22
Some background:
I suffered from the Android Process battery drain up to XXJVR. Flashing XXJVS seems to have improved things (after numerous reflashes of XXJVR and XXJVQ which didnt help. My phone's cpu keeps between 1% and 3% when sleeping, but i have noticed that Cpu rockets to like 30% as soon as i leave my house to go to work, or leave work to go home. Its as if the phone keeps trying to connect to some network all the time, but only while in motion (and trying to lock in from tower to tower?). The problem is however that Systempanel nor the log give great clues where to look.
Examples:
In this first example, my phone is hooked to the charger during the night, and the alarm clock is running (hence the steady 10% cpu load). As soon as the phone is disconnected, cpu drops to low levels. On the exact minute i leave home, cpu rockets. And yes,i arrived at work around 07:50.
Home environment:
- connected to wifi
- good 3G coverage
- 3G, Bluetooth,GPS enabled
- no Bluetooth profiles present
Work environment
- wifi network present but not connected
- average 3G coverage
In this second example, i'm at work, hardly using the phone. Without touching the phone, stepping into my car and driving off, the cpu kicks in again. Notice there is no Device Usage whatsoever at the moment the CPU climbs. Bluetooth profiles active at this point and paired & connected to the carkit.
This last screenshot shows the typical clues (or lack thereof) that SystemPanel shows: just the System process using the most CPU.
Also the logcat doesn't provide much clues (or too many maybe) either. I have found that some applications couldn't contact GoogleAnalystics because i have AdFree installed, so i uninstalled those apps.
Frankly, i don't know where took look further. The damn android 'System'process just doesn't give enough clues. I have formatted internal & external SD, deleted cache & Dalvik cache, flashed & factory resetted to no avail. I'll try to have a log running tomorrow morning just before leaving the house to see if i can find what log entry corresponds to the system process kicking in. In the meantime, has anyone ever seen this behaviour, or any hints where to look?

in short words - bull****
i have not touched (freezed/deleted) any app
yet still i have not noticed a drain, any kind of drain
let him determine what app is causing the 100% cpu usage first
prior to advising him to freeze or delete anything - that is wise you have to agree
also localization service would not provide such high cu usage

Hi,
It might be facebook 1.7.1. There are several complaining comments that "upload manager" process is running in the background and prevents phone from going into deep sleep mode.
i got data connection active all the time with all apps syncing (gmail, twitter, facebook)
and phone got no problem sleepin =)

i think you should go out and do some thing better with your life then watching what a battery uses
i think its a waste of space to quote WHALE post
and well if he got battery drained overnight it is important to determine why
it should not happend
Just a quick question, where is the phone when you are in the car? I have noticed that if I keep my phone in my trouser pocket while driving, I loose signal frequently, shown on Bluetooth unit, and over a 3hour journey I can loose 30% battery, but if I put the phone in my shirt pocket I do not loose signal and my battery loss is about 20%.
My theory is that the phone signal finds it easier to penetrate the glass windows of the car rather that the metalwork.
Similarly to Geryatrix, when I leave my phone beside my bed (=~~, best place for alarm), my battery drains because the phone stays with a very low network signal and keeps searching for better antennas, I guess. But then at "Battery Usage" I could see that "Cell Standby" was eating my bat, not the "Android System".
battery drains from wifi staying connected in idle state - thats a bug in my opinion from samsung - it should not use such ammount of energy
data connection in idle is almost unnoticable in battery use
When I had facebook 1.7.1 installed, "Android System" was consuming 20% battery.
After I uninstalled facebook 1.7.1 and the problem is gone, "Android System is back
to normal, about 4%.

seems like one of apps you use is trying to connect somewhere
have you made bugreport - i think you will find the culprit there
Have you tried disabling fast dormancy? Maybe these wakelocks are caused by incompatible 3g cell.

Hi,
I have opposite experience. Keeping Wifi enabled causes almost no battery drain for me, keeping 3G enabled does big time. My Galaxy Tab 10.1 Wifi version is set to never let the wifi connection sleep, and still battery drains no more than 1% or 2% a day is the tablet is not used.
I tested today with Wifi disabled. Still the Enter Dormancy messages appear each 5 seconds, altough the CPU hit is less. The Fast Dormacy messages seem purely cell-tower related, and wifi-unrelated. The Dormancy messages start as soon as i start moving, and stop when i'm home. I will update the startpost agan tonight.

Installed anything just before the drain problem?
Pretty much all the problems I've had with battery drain have been traced to an app misbehaving. The battery stats info can be a bit misleading too - so don't trust that the OS itself is draining the juice... Its more likely to be some service app that doesn't show up a itself on the stats.
I've found Widget Locker a painful battery hog, for example, but it never shows up in my battery stats. Instead the Android OS, or whatever last write to the system log (log cat) show up as using all the power. Uninstalling WL always fixes the problem so I know its that app causing the drain.
Also, is that shield in your notifications bar some sort of battery saver?
If so it may be the cause not the saviour! I've read that the latest free version of Green Power tries to connect to ad-servers constantly and drains the battery double-quick. Apparently the premium version doesn't have this issue but you have to pay for it, obviously!
the issue is undoubtedly running services..you probably added an app or three that is high maintenance.
shut down and restart your phone and then without starting or using any apps, leave it overnight to get a better benchmark for battery life.
If still low, look at the running services, you may be staggered to see what amount of crap is running in the background..

Mine hasn't had any new apps installed and normally loses about 7 percent overnight. The shield in the pic is lookout which I've always used without a problem. I have restarted the phone so I'll see how it goes today. Its wierd because nothing has changed in use or apps so something must have hung and run it down.
I'll post any other findings!
