Samsung claim 625 hours of standby for the i9000, best case situation I know. But as it stands with 2.2 JPO I am losing roughly 8% per hour in standby under what I would call normal data syncing and what seems to be about 5% ph when all data is off and the signal is strong.
So rather than discuss causes in this thead I am just wondering would people put down their power consumption (if they noticed) and their firmware? It would be good to have an average before wondering how to fix what might not be a problem.
652 hours standby? lol where did u get that? heck doesn't the ipad have 30 days standby? and it has 3 battries!
I tried once overnight with flight mode on there i got 1% drop in 7 hours ... this was at JM2 original firmware. Normally i get 25% drop with normal use within 12 hours and juicedefender (switches on data connection once per half an hour for email sync).

It has 2, but point taken.
And I got that information here:
http://mea.samsungmobile.com/ENG/mobile-phones/samsung-i9000-galaxy-s-specification
The biggest problem with the battery is the screen and white backgrounds ...It users double what a LCD screen dose with white backgrounds so when your on the net your battery will drain faster

Standby means screen off.
I think the 625 hours standy means phone on, screen off, wifi/gps/data/3g off.
Yes and best case means tested in the factory so:
-No SIM Card
-Raw software (no apps installed)
-No external SD inserted
-Phone turned on and left there untill it turns it self off.
(read that somwhere cant remember where)
BTW: 31% Battery drain within 10h
-Processor overclocked (1,2GHz)
-Performance Govenor chosen on SetCPU
-Data deactivated 6h, Data connection active 3h used 2h
-Wifi on 1h, used 0.5h
-38mins on the phone
-37 SMS writen, 46 recieved
-1h Listening to Music (headphones)
-Running JPP/JPA with super optimized JP6-JPM
-All partitions ext4, looped ext2
Was that percise enough?;-)

Yeah I suspect the "best case" too of course. But man, 31% in 10 hours? At my rate I would be flat in ten. Doing nothing, no screen interaction and minimal syncing.
I think mine is hardcore hardware knackered.
Also thanks for the specifics, that is a great insight.

U just remindet me, i forgot to say my screen is set to automatic, and most of the time its on the lowest setting. There is a big difference what kernel and format u use. When i had it set to jfs file system my battery was down before i got home (10h is a normal working day including the way to and from work). Most of the battery was used during the brake. Tomorrow at i will pay more attention ti the battery drain during brake and report again
Edit: got home at 6pm and my battery was on 69% now its 10pm 45% left and i was using the internet and tapatalk (over wifi) the whole time. So thats another 24% battery drain in 4hours of full usage.

I have offed all data and even the attempts to sync on my phone. The screen is minimum all the time. This is making me nuts here!
24% seems incredibly low for 4 hours of actual screen on time. This is an unmodified OS, just the new 2.2 JPO.

Its official jpa with superoptimized jp6-jpm kernel all partitions ext4 with ext2 loop. Syncs are turned off background data is on. I have minfree manager setup to keep as much of my ram free as possible. First ive.set it too high so my phone crashed. Actual setting from top (visible app) to bottom (hidden app):
40
60
90
125
128
130
Maybe thats one of the reasons?
Edit: by now i know that u can improve your battery life with differwnt things but i dunno what exately it is. Ive changed so many thigs the last 2 weeks. And sometimes my battery was empty @ midday and sometimes it lasted 1.5 days. Phone usage is about the same every day.

Screen on time will always be 10-20% drain per hour on the stock battery.
Anyone who thinks otherwise is kidding themselves, 10%/h is VERY optimistic, that's 10 hours guys
Sent from my GT-I9000 using XDA App
Well I used to get 1% drop every 8hrs of standby, this means that GSM radio is ON but no other functions are running. So if you do the math.. 600hrs is very possible in a certain condition.

25% per 2hrs of screen time seems to be the norm
It depends on what you are doing and what screen brightness. If you are playing a game at max brightness you could kill the battery in 2-3 hours. Watching low quality video at low brightness can go on for 8hrs

I've noticed that the quality of a video wont really affect battery power that much.. compared to a VCD quality movie and a 720p (5mbps) I think the GPU can decode it very efficiently.
But I DO notice a difference between the stock player and mvideo player in terms of power usage.

I'm starting to think your one is wrong! But in a good way..
With everything off bar the WCDMA connection I lost 6% in 10 hours. I suppose that is reasonable, but again the phone was doing absolutely nothing.
well I got a JPD firmware with lagfix
Even with screen off and flight mode on
it still drain at least 30% of battery during sleep
(Which it only drained less than 10% in JI1)
I have problem with my s3 mini.
I used stock ROM. it's still official without any root or something.
My baseband is DXAMB1.
My problem is, when I start my phone, the battery life up to 18 hours. But after 70-80 hours up time, the battery suddenly really sucks.
it just about 9-10 hours a day. For example (I forgot to screen capture), I charged my phone and full at 11 pm and then in the morning (6 am) it says my battery 50%. When I look at the battery status it says Android OS stay awakes for 6 hours.
After I restart my phone, it back to normal. When I woke up, it says 80% battery and Android OS stay awakes for 1 hours.
Everytime my battery life become sucks, I need to restart the phone.
Is anybody have the some problem with me? And how to fix this?
It just sucks that I have to restart my phone every 3 days.

Are you rooted, if yes try using Better Battery Stats from xda and find out whats draining your battery
I'm not rooted yet.
But Du Battery Saver said Android OS is draining my batteries.
Even in battery saver mode.
I will give screen shot after if it happening again.
Do you know why Android OS consumed much power?

I was pretty curious about this option too, some time ago, so I googled it and finally came to the opinion that it is like using a task manager, = useless on Android, because it has its own RAM manager.
This option to limit process is what it is: for developers, to test how their eventual app handle once it goes in background, and what if once killed. (read http://www.extremetech.com/computing/112013-how-multitasking-works-on-android-and-ios/2)
My personal advice/choice for a longer life for your battery:
1 - root your device and freeze/delete bloatware (system apps: first freeze them, see how it goes, then, delete them (after making a backup)
2 - use
A) Juice Defender (balanced or aggressive), set 2g connection when the device is in your pocket,
B) Use Wakelock Detector to check what most consumes your battery (https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en)
3 - use wifi and 3g only when needed, - don't count on the smartness of automatic mode 2g/3g under data
4 - switch off syncronization if you don't need it 24h (whatsapp / viber will work anyway)
5 - settings / display /
A) Auto adjust display tone ON
B) Turn off softkeys (I know exactly where 'back' and 'option' keys are..)
6 - Power saving mode ON for screen and cpu (http://www.youtube.com/watch?v=XTLTBo2DRQA)
7 - Disable double tap on home button for S-Voice (http://www.youtube.com/watch?v=OmU8hXUXNFE)
8 - Keep normally a mid-low brightness level, you can adjust it quickly if needed, can't you?
9 - Disable Auto-update in Google Play (you can update manually)
10 - How To Disable Samsung Push Service and Samsung Ad Utility Services (http://www.eyes4tech.com/2013/03/ho...e-samsung-push-service-and-samsung-ad-utility)
11 - Turn OFF vibration (actually, I like it and I use it for SMS and incoming phone calls)
12 - Set airplane mode when you go to sleep (or just switch it off if you don't count on it for morning alarm or to use it as an eventual light)
13 - Never use a Task manager
Assuming you're enough smart for keeping Bluetooth OFF if you don't need it, by this way, according to my daily use (phone calls, texting, internet, no gaming), I recharge it each 1d 15/22 hrs.
Hopefully this helps. :cyclops:

Mine (bought on March 2014) with power saver on goes from 100% to 96% in one night (data, Wi-Fi are off). I think that is normal. Battery lasts 2 days normal use (not much screen on).
You can do a Factory reset. Don't install apps and watch if the drain is still there.
1. If the drain disappear install your apps one by one to see witch cause the drain.
2. If the drain is still there send it to service you have a battery problem.

Did you installed some apps that may cause?
Is this brand new or used phone you bought?
need a bit more info.
go to settings - power - usage, and look at the app usage. You should see the typical apps you use a lot, but also look for apps that look out of place. like an app you don't use much, but uses a lot of battery use.
also look at settings - more - data usage, and scroll down. That will show which apps are using the most data, and also if it's foreground or background data. Don't worry too much about foreground data, that is data use happening while you are using the app. Instead, look for apps that are using a lot of background data. if you click on the app, you have an option to disable background data for those apps.
Note some apps don't function properly without background data enabled, like some google services/play store. also make sure the play store options are set to never auto update.
fwiw, I usually get 2.5-3 days between charges with light use.
Sounds like a major issue

If the phone is that brand new, it could be a malfunctioning phone that eats through battery life. I would try taking it back to where ever you bought it from and try getting a new phone. See if that helps. Otherwise you may need to purchase a different battery from a reputable seller in order to get a good amount of battery life.
Cheers!

Those should be on the top of your list. You might have a faulty battery then. Have you tried a factory reset?
So, I tried a factory reset but still battery drain. I have another HTC One, with heavier usage and still goes all the day with 30-40% left at night. I will talk to Vodafone to sent the phone to warranty but I think they will say It's because you unlocked the bootloader, put a custom rom, and there is a chance to lose my warranty. Probably I'll buy a battery case

You could Greenify the apps running on the background. That way, they will only be running when you open them and not after you close them. This could help too.

Actually the 4 minutes per battery percentage happens on heavy usage. When you just do normal things like messaging and other stuff, your battery holds its power even more better
RAM Management problem is a dominant problem of the Xperia SP. You can use Greenify [Play Store link]. However, non-root is not as breeze as boost or root-mode but it should accomplish your need.

Not easy to see from only that picture. Enter android entry and see what cpu time is and so on, also show hardware usage
If it's not a fresh install I would recommend clearing cache on the phone from the recovery if possible. Usually helps
