I use JM5, Wifi Always on, 3G Always on, Auto sync off when unnecessary.

I was working at the polling booths on Election day here in AU, that's from 7:30AM till 11:30PM, I didn't really need to use my phone for anything, but when I got out 16 hours later I noticed that I had only lost about 3-4% battery.

It's pretty good. D:

For the record:

Bluetooth - This only needs to be turned off if there are devices that auto-pair with the phone, such as a bluetooth headset, in which case you probably want it on anyway?

GPS - This does not need to be turned off as it only uses battery when a service is actively requesting a gps fix. For example if you have Maps open it will drain more battery, but it won't on standby unless you are using Location tracking software or otherwise location aware software.

WiFi - Truth to be told, WiFi when connected uses less power than a 3G connection on standby. WiFi does have the potential to use a lot more power than 3G because of the higher speed potential over a local wireless network. In most cases it's pretty safe to have WiFi always on, however it should be noted that when WiFi is NOT connected it will constantly scan for access points to connect to, this process uses power ON TOP of 3G, so it would be wasteful to leave this on unnecessarily unless you were using it for Google Location services via WiFi access points.

3G Data - The only reason this 'uses power' is because it's a always-on connection, you can partially remedy this by giving WiFi always-on priority saving both mobile data quota and some power. 2G uses a lot less power than 3G simply because it uses the GSM chip in the phone, not it's own higher power chip. So switch to 2G if u don't need high speed data, but want always on Push notifications and such. (EDGE is fairly fast, but I only get GPRS and 3G on my carrier. :( )

Brightness - This phone has a super bright screen, use something in the lower settings, auto brightness at day if you want.
[Galaxy S I9000 General] MoWa22:
I've got bluetooth off all the time, it's currently running a very new install of JM6, and I haven't installed anything that runs when I don't want it to run. 3G isn't used, as wifi is always on (advanced wifi settings).

It's around 7 hours since I pulled the plug, after having restarted phone after removing SD card, and the suspend process isn't even on the list anymore... I find this quite interesting - it might just be a coincidence, but right now it looks like there is some kind of problem with suspend process when SD card is in... Do you have an "external" SD card in your phone?
[Galaxy S I9000 General] sensi_:
ive just flashed JM1 and hate how much power its using... no idea what the problem is, but ive just come off the official JM1 from Kies, and had a big problem so had to flash the first thing i could find. can this really be down to firmware?

i mean im really noticing a difference on standby, before id loose like 3-4% in a whole day of not using it, now it drops 10% in like a few hours...
[Galaxy S I9000 General] MoWa22:
Do you have "external" SD card?
[Galaxy S I9000 General] AllGamer:
i do use 16GB class 6 external SD from Transcent
[Galaxy S I9000 General] Zhousibo:
MoWa22,

I had this happen to me last night and (am stock DXJG04) so very interesting. Trying to remember what my battery drain was last night but I think it was around 10-15% and previously I would get 1% if I turned everything off except being able to receive calls.

I always thought these issues were related to wake locks or that the phone just cannot sleep. Something to try is to reboot the phone and check the battery power before going to sleep and see the battery drain over the night. If minimal battery drain, then maybe it is a rogue app which you may have opened/used during the day. If same 8-10% drain, then am guessing some service or inbuilt process is causing issues.

Half the battle is trying to track the CPU hog or rogue app.
[Galaxy S I9000 General] MoWa22:
Dang. Lost almost 10% again tonight - but actually the "suspend" process almost didn't use any CPU, SD card still not in phone. Using the built-in battery usage thing, it has cell standby on top, phone idle right below. This is really starting to bother me...
[Galaxy S I9000 General] Zhousibo:
Last night while I turned off APN, Wifi, GPS, etc, I left my phone on as 3G only. I've heard the switch between 3G to 2G causes extra battery drain so I had left the phone on as 3G only. I know 2G is lot less of a battery strain but wonder if it affects cell phone standby. Going to leave my phone on 2G tonight.
[Galaxy S I9000 General] mib1800:
I have 3G and sync on. I have weather and feed widgets updated every hour. Plus some other widgets and Google Latitude which I know is using cpu time. My drain is about 1 to 1.2% drain per hour of standby. Firmware DJG4.

I think you dont need to bother too much if battery drains 1-2% per hour on standby (this gives you at least 2-4 days if you use the phone very little). Any more than this means you may have some rouge apps/widgets.

The more critical is the usage time (i.e. with screen on). This is usually like 15-20% drop per hour of use.
[Galaxy S I9000 General] MoWa22:
Been testing a bit again - this night I had a total of approx. 1% battery used in 9 hours. :) Still without SD card. I inserted the SD card one hour ago, and I've lost 5-6% already - and suspend process is on top of the list again... Definately something weird going on when SD card is inserted! Please, can anyone test with/without SD card and check for differences?
[Galaxy S I9000 General] newtonthecat:
I spotted this thread and read with interest as last night I noticed my power dropped "unreasonably". I've not started any troubleshooting yet but I am curious about the SD card thing.

Have you tried having the SD card in, but unmounted? Does it still suck powere when unmounted?

Obviously unmounting it is a simpler and quicker process than removing the cover and then physically removing the card.

Mark.
[Galaxy S I9000 General] MoWa22:
Upgraded to the new Froyo today, seems to be without suspend problems even with SD card. Gotta check how much battery it'll eat during the night. :)
[Galaxy S I9000 General] MoWa22:
2% drain during the night. Uhm, I like this. :)
[Galaxy S I9000 General] Spybreak:
How did you manage that? Everything off? auto-sync off? Wifi? 3g? 2g?
[Galaxy S I9000 General] Qazz~:
I'm on jm5 with Samset 1.9f and for all the time ive had this phone it has only used 2% battery overnight. Exceptional cases were when i used Fancy Widget, it ate up all my battery overnight leaving me with nothing for the next day. Have stopped using it ever since.

Nowadays, my battery drains heavily when screen is on(when im using the phone). Drains roughly about 1% for every 2 mins im using it, but standby time is still great at 2% overnight...
[Galaxy S I9000 General] MoWa22:
And do you by any chance run without "external" SD card?
[Galaxy S I9000 General] MoWa22:
The new Froyo beta JPC. Same settings as always - WiFi always on (which by the way seems to be default setting on JPC). Everything else standard (it won't switch to 3G while using WiFi).
[Galaxy S I9000 General] borchgrevink:
My phone drops like 10% every hour. 100 + applications installed. Any tips on how to spot a rogue app?

Macados external sdcard lag fix

I have tested the phone batterydrain at night.

Without the SD card the phone use like 1% battery at night.

With the SD card it use like 20 % of my battery over 8 hours idle.

Tho this can be caused by the fact that I use the Macado external SD card lagfix. No app will basicly be able to run when the storage for the userdata is missing.

Have not tryed with/without SD card when there is no lagfix applyed.
[Galaxy S I9000 General] MoWa22:
Great. Well, it isn't, but it's great that others have the same problem. :) Froyo JPC seems to have fixed it, luckily :)
[Galaxy S I9000 General] borchgrevink:
Thanks. I'll try.

EDIT: How do I actually use it to spot a rogue app?
[Galaxy S I9000 General] MoWa22:
First of all, install it. :) That done, plug the charger in - just for a few seconds - and unplug it, only goal is to reset the counters that Spare Parts will show you. Let your phone have a nice little rest - overnight isn't a bad idea. Open Spare Parts. Select "Battery history". Click the top drop menu and select "CPU usage". At this point, don't click anything - wait for half a minute or so, for some reason the counters won't be shown unless you do that (although it seems the JPC Froyo will let you view them almost immediately). Check out what has been using CPU during the sleep. You can also try the built-in battery usage analyzer in the Android settings menu - "about phone" - "battery use" - could also tell you something.
[Galaxy S I9000 General] alovell83:
@borchgrevink,

I'm not positive, but I'll do my best. Please note, when in the app, try to click on the value/percentage given in order to get more info at all times like secs/mins/hours on...:

Go into the app, click on battery history, then click on partial wake usage (the app might not be called out, but if they are this is probably where you'll get the best info...otherwise they'll just be put into Android System). You can look into your since unplugged stats and also all time, both should be informative if they give any specific info

if that fails, look into your CPU usage. Information here will probably call out quite a few more apps, and for the majority of information displayed here will probably be active time when you were using the phone, the key would be seeing something that relatively out of place based on your usage pattern (a problem with this approach is I'm not sure if you will get a complete app listing, the results might get cut off a bit, which might not get to that random app that wakes up for a 5-10 secs here and there).

Hopefully if I missed the boat someone will chime in. Let us know if that helps or not.
[Galaxy S I9000 General] Zhousibo:
I think there is something with the SD card causing battery drain.

Been using my phone slightly differently by charging all night and using all day. Yesterday drained my battery to 10% (5 am till 10 pm on light usage and doing stuff like turning off 3G and APN). Before going to sleep last night, I rebooted and pulled my SD card. Checked this morning and only 1% drain.

Guess will just need to wait for Froyo. Might try unmount the card overnight.
[Galaxy S I9000 General] sh1ng0:
i tried unmounting my SD card with service limited to 2G, gps off, wifi on and its sucking 11% of my battery overnight (7 hours and 30 minutes standby time). is this good or bad? maybe i should try to remove the SD card completely.
[Galaxy S I9000 General] Qazz~:
From what i know, Modaco SD card lagfix is a battery drainer as it is constantly keeping the sd card active as it is now "part of the system memory" This will significantly affect the battery life. Btw I'm using ryanza One click lagfix and do not have an sd card

I'm new 2 the rooting and the Android itself.. I got the 2.2 on my EVO like most ppl have via update, I'm kinda skeptical of rooting it still.. I guess my question is, is it worth rooting it and what changes on the device itself?

Any information would and will be extremely appreciated..

Thanx in advance...
[EVO 4G Q&A, Help & Troubleshooting] nenn:
Good day to you.

First off. welcome. second, as its your FIRST post I hope you wont get flamed too hard because there are many many threads that cover the pros/cons of rooting.

I suggest next time you have a question, take a minute to use the search function (and post in the right forum! questions go in Q&A).

A few quick pros of rooting.

Free wireless tether (sharing your phones internet connection with a laptop or other wifi enabled device)

The ability to flash custom ROMs, these are the operating systems of the phone, they're all built off of (for the most part) stock htc/sprint images, but there are plenty and many options, find one that suits your needs and try it out.

Custom kernels, they are the set of drivers and the "brain" of your phone, want it overclocked? get a custom kernel, want it undervolted (Save battery) get a custom kernel. many options to choose from

Custom Boot screens.

Root only applications, titanium backup (backs up stuff, i dont use it so i cant elaborate), shootme (screenshot program) and others im sure.

Hope this clears up some stuff, welcome, use the search (really im just trying to help ya here) and have fun!
[EVO 4G Q&A, Help & Troubleshooting] rugedraw:
Round of applause for nenn. While I agree with your first few sentences, there aren't many "nice guys" on this site and especially on the Evo boards. People tend to forget that this phone is relatively new and has attracted many new people to the world of Android (like myself) who know nothing about anything.

OP: A few things you can do with root that nenn did not mention:

1) You can read/write from your SD card.

2) You can remove all the garbage that your phone came loaded with from Sprint and HTC (like Sprint Nascar and Peep).

3) With Titanium back-up, it allows you to transfer all user apps to the SD card keeping your phones internal memory clean, you can back up and restore all apps and system data, and you can use it to uninstall apps you don't want as mentioned in point #2.

4) Custom kernels also remove the 30 fps cap on our phones (I get 52 fps average with my set up).

5) You can use other root-only programs like ROM Manager which lets you flash files onto your phone easily via a custom recovery. Also, you can back up several ROM's and switch from one to the other, or go back to a previous working ROM if you flash something on your phone that doesn't sit well with it.

If everything that we have mentioned means nothing to you, then just enjoy your phone as it is. It is a great device and you can get plenty of use out if without rooting it.

Hi Guys

This thread is just to express gratitude to the guy behind post:

[UTIL] LagFix using update.zip's - v2.3.2

http://xdaforums.com/showthread.php?t=765820

____________________________________________________

I come from an Iphone 3GS background and I bought my Galaxy S a month ago, and after trying the phone with the firmware that came with it (JF4), I almost threw the phone at the wall

I upgraded then to different firmwares that kept floating on the internet until i finally settled on the JG8. This latest firmware was good but there was always annoying lag and occasional freezes here and there and some applications always took time to load (2 to 5 seconds freeze after i click the icon)............

Through my experience and posts i read in this forum i humbly concluded the problem was two folds: RAM and file system

So i decided to tackle the problem using two approaches, a memory manager, and a file system fix

so i installed "Auto Killer" from the market and set it to "extreme", and installed the lag fix v2.3.2 posted by Tayutama

I constantly get around 150 Mb of free RAM and My SGS now is even better than the 3GS in terms of fluidity and responsiveness,and on top of that i have an open operating system as compared to the closed limited Apple IOS

I dont know what the coders at samsung mobile are doing, but they definitely have to take a look at what is happening at XDA forums

I almost sold the phone a couple of days ago, but now i would not sell it for double the price.

out of being realistic, i have to say that the only problems still at hand now are the following:

1- slight freeze when an app has fully downloaded from the market and is being installed. My old 3GS never froze during app installation. I really dont know how apple has managed to pull this up

2- If you're using the SGS as a business phone (which i am doing), then syncing with outlook is of great importance (calendar, contacts, notes, tasks) and still there is no application than enables you to do those on the SGS. Kies is a ****ty (pardon my french) piece of God forsaken software that needs a lot of improvement

Peace out
[Galaxy S I9000 Android Development] mickeko:
I have no clue why ext4 wouldn't make sense to use. But let us for arguments sake say that it makes the phone unstable in some way (poor implementation in android or whatever the reason). That instability is likely rare, but if 1 out of 500 people experience dataloss because of it, it would be 10000 people experiencing dataloss on the phone (with 5 million phones sold). That's not acceptable, and compared to that, the lag is preferable.
[Galaxy S I9000 Android Development] The.Opethian:
Very nice and informative post. In regards to the data loss, one can agree on that. I think most people who come from iPhone to SGS know what they're getting into (XDA that is :) )
[Galaxy S I9000 Android Development] RyanZA:
Yeah right, android is still just stock linux at it's core. EXT4 is far more tested and robust than RFS. The reasons for choosing RFS cannot be technical, because RFS is technologically antiquated (it has all the performance 'features' of FAT32).

There is far more chance of data loss by using RFS than there is by using EXT4. Data loss in general is just plain unlikely on a super fast NAND device connected to a permanent battery like the internal SD card in our SGS. The main reason for things like 'safe' filesystems is because of slow physical magnetic write media (which used to be able to make mistakes when writing), which would stop spinning as soon as power stopped, leaving you with a long line of incorrect data.

Phones are just plain unlikely to ever have filesystem data corruption because of the very advanced NAND controllers on the storage devices. It is probably possible, but it is also possible for the battery in your phone to melt down, and burn your hand.

EDIT: Just to add, since we are talking about filesystems: the mythical magical iPhone (2G/3G at least) uses a non-journaled HFS+ filesystem for it's storage onto a NAND flash device - just the same as the SGS.

Non-journaled HFS+ is very very similar to EXT2. Nobody on an iphone has lost data because of their non-journaled filesystem (although you can't pull out an iphones battery). EXT4 is safer still than EXT2/HFS+. Just to put this in perspective when talking about mythical 'data safety'. ;)
[Galaxy S I9000 Android Development] RADLOUNI:
How is it that other phone vendors managed to uphold both, data integrity and speed (you know which vendor i ak talking about)
[Galaxy S I9000 Android Development] xan:
THC? ouch I meant... ***

Damn those letters.
[Galaxy S I9000 Android Development] RyanZA:
1. Non-removable battery. (You can get this same effect on your SGS by not removing the battery while the phone is on)

2. Very solid and fast (if a bit antique) HFS+ filesystem, that is similar to EXT2.

That is all it takes. ;)
[Galaxy S I9000 Android Development] EarlZ:
Can anyone tell me whats the real difference between the EXT2 and EXT4 based on the lagfix ?
[Galaxy S I9000 Android Development] hnr2802:
i like to know also.
[Galaxy S I9000 Android Development] RyanZA:
The currently lagfix makes a buffer between android and samsungs' RFS filesystem. EXT2 is a simple buffer that works very well and is fast. EXT4 is a more complex buffer that is believed to be more safe.

Possible differences:

Pulling out the battery while the phone is running may be safer in EXT4, as well as data safety in general may be better. No conclusive tests have been done (or possibly can be done) to determine this, though.

Real differences:

EXT4 is slower than EXT2.

Real solution:

Remove RFS entirely. Hopefully soon. :)

I don't know what you are talking about here, Android has over the air exchange sync of contacts, mail, and calander built in.
[Galaxy S I9000 Android Development] tndb:
Exactly what I was about to mention, and if you really wanna use outlook together with google calendar on phone and web, then simply install google outlook sync http://www.google.com/support/calendar/bin/answer.py?hl=en&answer=89955 and have them work together with w/e mailsystem youre using.
[Galaxy S I9000 Android Development] andrewluecke:
For starters, it might be because nobody actually knows if running EXT4 exclusively performs proper wear leveling with this phone (because nobody has actually checked where wear leveling is performed). Filesystems which do perform wear levelling and such do tend to be a lot slower than ones that don't. Is it possible that the lagfixes are flushing the data much less often too? Because, then it's additional speed, at the greater risk of losing data..
