Get a 3G killer widget or app as leaving it on is just wasting power.  Then on when needed.  Set display to auto settings.  Get "automatic task killer" from market too,  better then manipulation task killer.  Also if you can then root ya phone and get "auto start manager" it let's get turn off unwanted services

I've got up to 11 hours battery life by switching auto-sync from the accounts menu under settings.

Hi there!

I'm a newby with Samsung Galaxy S two days old ( Big Grin). 1st day battery consumption was about 16 hours as I tried to figure out the settings, application, etc. 2nd day or today @ 12am or 4 hours after unplugging the charger, the battery status is 82%!..If with the same momentum of usage..I think tonight, i need to recharge this smartphone again.. Sad (4 hours=20%, 20 hours=100%). As information, this what i'd done:

1)Install advanced Task Killer with 1/2 hour auto-kill
2)Use non-live wallpaper
3)Disable Auto-sync
4)Put phone on idle after 30s
5)Recharge battery once phone battery is drained off totally.
6)Screen Brightness (auto) as recommended or I should put it on minimum?

Any other suggestion or comment? I'm 3g user..

Thank You.

Having had the Samsung Galaxy S i9000 since the 13th of July, I am very impressed with this smart phone.
The biggest fault I discovered is the very fast draining of the battery and the occasional screen freeze.
The battery needed to be removed on one occation.
Thurs 29th July for some reason after a 100% recharge, the phone charge lasted 5 hrs 50 minutes from a 100% charge.
Vary Bad. Wasn't able to connect to the internet in that period either.
Recharged to 100% and 12 hours later the battery only showed 40% remaining.
I rang Samsung yesterday and they thought the 5hr drain period was unacceptable, but the other discharge times were standard.

There advertised standby time is calculated when the phone is in flight mode and nothing is running.
He recommended a task killer app, and also an app called APNdroid, which kills all of your internet connections and sync.
Last night found and installed the apps.
I used the apps after a 100% full charge and today 14 hours later the battery showed 96% remaing. A big improvement.
Phone still works on normal phone mode allowing calls and text alarms etc.

To re-connect or sync just use the app button again,  WiFi needed a manual switch on.
I put a shortcuts for both apps on the idle screen one

When you are fully connected, remember Only use 2G not 3g unless really necessary.
3G uses a lot of battery power for some reason.
Have your screen settings to the lowest acceptable level and auto turn of between 30 to 60 seconds
or force turn off with the switch on/off button
The sleeping time for WiFi setting should be, to turn off when screen turns off. This is the better option.
Switching to never seemed to drain the battery continually.
GPS, switch this off unless really required.
Keep you bluetooth off at all times unless required. This is a big battery drainer

I trust this information is some help

*********************************************

Battery Test with everything disabled apart from the normal phone, SMS & MMS functions

The phone was used for the occasional calls

30th Jul 2010    1750   100% charge
31st Jul 2010    0950    97% Charge   After 16hrs
31st Jul 2010    1750    91% Charge   After 24hrs
1st Aug 2010     1145    80% Charge   After 40hrs
1st Aug 2010    1750    78% Charge   After 48hrs

All pretty good with the phone only connected

Sunday 01/08/2010 Clicked the short cut to re connect to the internet and nothing. Showed I was connected
but opening a web page I was informed there was no network connection.
After 90 minutes enough was enough. Battery drained to 65%
I decided to un-install the APNdroid app. I did remember to have the app stating that all was connected again
before the un-install. Reboot of the phone just to be 100% sure and all back to normal.
I can now only hope that the update amy fix some of the battery drainage problems otherwise stuck with it
until another working app can be found.

All I can say is Bugger !

UPDATE

After the android update and having to reinstall most of my apps, fortunately backed up to my SDcard, and thank god for that.
Re-installed the APNdroid app. This time in installed correctly. Switch it on meaning disconnect all of the web data stuff, the phone has now 50% left in the battery after 4 days, that is 48hrs with minimal phone and text use. Switching APNdroid off (and working immediately this time) just to check a few email and maps stuff and sync the calender or email when away from home. Thats a couple of times a day, but immediately switching back on immediatley after use. This is the what to go. By the way, switch of the WiFi, BLUETOOTH, GPS, SYNC, and averything else you can think of, and the battery will last. USING THE INTERNET DATA, GPS, SYNC, WIFI and BLUETOOTH is the KILLER.

+1 - Mind your connectivity. Being new to Android, I always wondered about the little 3G icon blinking in the corner even when I had all my apps set to manual sync! On a hunch I checked my bill online and I was indeed incurring connection charges! APN on/off took care of that and I'm now getting at least 2 days of heavy use.

Well in a land without proper 3G, the EDGE saps out the battery on mine.

I try to keep my tasks in control with some applications that can help with that. I also turn on Sync and Talk when I have good WiFi connectivity.

It also helps if you reboot your phone once in a while, although not logically - just an easy 'refresh' way. Logically you'd control your android services and background data pullers.

Hi all,

sorry for opening another battery thread but my Galaxy S is incredibly power hungry.

My last phone was a BlackBerry Bold which could hold 3 days on a single charge (2 email accounts, Facebook & Twitter apps, aprox.20 minutes of calls and 10-15 sms daily) so I was quite surprised when I found out that a SGS last for less than 24 hours! Seriously, this morning when the phone was telling me to recharge it, it had been 17 hours from the last charge and 6 hours were during the night in standby mode.

I got the phone on tuesday and the battery was on 50% so I was using it until it was low because apparently, the story about first charge lasting 5-6 hours is now outdated (as I heard) for the Li-ion batteries have no memory effect.

I have two home screens, Daily briefing, one Hotmail account (updated every one hour), Twitter and Facebook apps (updated every one and two hours respectively) and AutoExpress app which is updated daily.

The screen brightness is set on automatic and the backlight on one minute, WiFi, Bluetooth and GPS are constantly off.

I live in an EDGE covered area, 3G is only in downtown (automatic setting)

Some say that battery life will improve over several charges, but shouldn't three charges show the results already? I'm not a big chatter, only 10-15 minutes of calls and several sms daily.

So is this normal or?

Everything you mentioned doing will conserve battery life, so it is something else. I do, however, have my battery set to manual and keep the screen as dimmed as possible.

For me, Pandora is a battery drain. Do you use a Live Wallpaper? Is your wallpaper primarily light or dark? I switched to a dark, static wallpaper and it seemed to help.

Check your running applications and see what may be running that you did not realize.

How to Increase Samsung Galaxy S Battery life


Samsung Galaxy S is power-packed with AMOLED screen and multiple applications, the camera and the huge interface surely speaks of eating up a lot of battery when you want to get the fullest use out of it. And you can’t blame the phone for draining the battery fast, as you can control it by few easy settings and steps that would reduce the draining of battery, and extend the battery life of the Samsung Galaxy S mobile phone. The 1500mAh battery provided by Samsung is good enough for just a normal use of a day, but I liked the way Galaxy shows the availability of battery for various functions. It restricts you to use certain applications and functions when the battery is low. Still, no one would appreciate when the battery keeps getting drained in these smartphones.

Here are the things you need to do -

# Play with the brightness
While you are at home, not trying to be geeky, just try to limit the brightness to a lower level which doesn’t use up much battery. The default setting that Samsung Galaxy S comes is the automatic brightness setting, with which the brightness of the screen becomes in accordance to the surrounding brightness. But that would keep the sensor on, and one of the reasons to eat up battery. Go to Applications > Settings > Sound and Display > in the bottom go to the Brightness setting and uncheck the option “Automatic brightness”, and then set the brightness to a low level.



# Timeout of the screen

This is a setting which turns off the screen display when the phone is idle, and you are not touching the screen. When you are not using the phone, what’s the use of having the screen active for long? Go to the same settings as above step, and just below the brightness, there is an option of “Screen Timeout” where you can set the time of screen turning off in just 15 seconds when it is idle.

# Flight Mode

This is a mode where the phone is stagnant, with no connection with the network or any other sources. It doesn’t eat up the battery, as the phone is almost switched off without any network. Flight mode isn’t just when you are on a flight (as the name says), but you can activate it when you are traveling or need no use of the phone and don’t want to receive any calls, or stopped using the internet.

You can activate this flight mode by holding the power button on the right side of the device, until a list of options appear on the screen, and then select the “Flight Mode”. This will activate the flight mode, and all the network connections will be lost. You can rather choose to have the network on, but other connections like Wi-Fi, Bluetooth etc. off. To quit Flight mode, just repeat the earlier process and you can activate the network connection.

# Restrict network to 2G

Usually any 3G phone does the same, they try to use the 3G network for the web connectivity, but connecting to the 3G networks is different from the normal 2G ones, and it uses more battery. When you feel like not having a need of 3G when you are not into a browsing mode.
To do this, press Menu button > Settings > Wireless and network > Mobile networks and in this, select the “Use only 2G networks” option, where the connectivity gets limited to the one you need.

# Vibration – Haptic feedback

Haptic feedback is the touch response which comes as a small vibration whenever you touch the screen, which is totally unnecessary except for when you really want to know whether you are using the touchscreen rightly. I would suggest to just shut that option off. Set the Haptic feedback off, as it can reduce some battery usage.

# Accounts syncing and background data

Syncing the accounts online with google is always on in Galaxy, and you are always kept connected to the network for this. This keeps running in the background, and the data transfer thus keeps working. This is one of the main reasons for the battery draining faster. I would suggest to just sync the phone with the Google services once every day, rather than keep it synced all the day.

For that, go to the Menu button > Settings > Accounts and Sync.
There you would see 2 options – Background Data, and Auto-Sync. Uncheck both of them, and you will see the phone itself boasting about battery life extending because of the disabled background data.

# GPS Settings

GPS drains battery, and that’s a universal fact. When not in use, try to disable it. Just tap the top menu bar and drag it down, and hit the GPS option to turn it off if its on. Turn on the GPS and location service only when you feel the need of using it.

# Power Saving Mode

There is an option power saving mode that comes by default in most of the Galaxy mobiles. If it hasn’t come activated in yours, do it and the phone will automatically start functioning on the ways to save more battery. It would work in the same way as laptops do when not connected to a power charger. To activate the power saving mode -
Open Applications > Settings > Sound and Display and there select the “Power Saving Mode” which analyzes images and also adjusts LCD brightness to save the battery.

# Audible touch tones

The audible touch tones are activated just like the Haptic feedback, which can be disabled to reduce the battery usage. You can do that by going to Settings > Sound and Ringtones > Turn off Audible tones.



The above tips would help save battery, but would also make your phone less geeky for sure. But, sometimes its good to think about the former, while you are in need of longer running battery etc. like during travel.
