mine lasts about a day so charge it up over night

 

Depends on what you call average use really,
I read for about 3 hours, listen to about 1 hour of music send a couple of texts and use the phone for about 140 minutes in a day and still have 40% battery life left when I go to bed.
The biggest drain I found was apps permanently on (auto kill required) and 3G permanently on with apps running background data (Quick settings app can cure this).

 

same here, I'm averaging 18-20 hrs.

 

Seems to vary, but it it needs charging everyday.

With heavy use 6-8 hours.

 

It depends a lot on what running. Having 3G+push email = like 10%/hour, so you have "just" 10 hours of battery life....
On the other hand, I often use it relatively lightly (1.5 hour internet/mail, 30min calling, 30 min other stuff), and it lasts 2 days on a charge....Over the weekend I use it even less, and it lasts for 4 days easily (now at 69%, 51 hours since last charge).

 

On Eclair you can get up to almost 3 days of usage.

On Froyo, you can barely get one day of usage. And it's Samsung's fault.

 

Three days if you barely use the phone at all, I only got one day out of 2.1 and everyone I know who uses this phone on 2.1 is having exactly the same experience, you are seriously exaggerating the difference.

Why?

 

What's different, and is that the final Froyo that we'll all get eventually?

Personally I find the display uses almost all the power that's used, and it'll sit in standby if I'm not using it for days, and last much less than a day if I use it heavily.

 

If I turn 3G off I can easily get over 2 days of phone usage, the same usage with 3G on seems to last less than 20 hours

 

Same, I can turn off the bluetooth, gps, wifi, sync and push it over 2 days and that's not even trying not to use it. I'll send and receive my texts and phone calls and it will still get the best part of 2 days. Probably 3 if I don't use it at all.

And I hope Froyo is an improvement in batter life, and not a step backwards.

 

My battery is terrible... LOVE the phone but with heavy use i have to charge it a couple of times a day.
Luckily since i have had it my main use is at home & work so had a charger handy, not lookig foward to full days out etc.

I heard that people have had a new battery sent out from Samsung if they moan LOTS... Might give it a go.

I have found if i play games/browse/listen to music solid, i get a few hours max.

 

I'd take it back to the shop and complain.
I had this issue with my Omnia and they gave me a new battery when I complained about it.

 

If you look at the battery usage stats, the super AMOLED display is the main hogger of battery juice, so there isn't much you can do about it, I guess that's the price you pay.

 

Battery really aint that bad compared to others, its just people are expecting too much out of a 1500mAH and on a 4" screen.

 

How can you turn the 3G off? And does turning the 3G off disable all cellular?

 

Don't get me wrong I'm loving the phone and don't regret getting it.
I'll get on to O2 this week and see if I have any luck, hope they don't want the whole phone back.

 

I use the app "APN OnOff" - a widget on the main screen allows me to turn 3G on/off whenever I need it...made a huge change - now I can use it for multiple days, whereas with 3G on all the time it is limited to 1 day.

 

Kasper-
Unless I am missing something, my Samsung Captivate does not have that widget. I double checked the manual and its not listed there either. Is the widget you are referring to a download?
Thanks.

 

You can use an app (I do) or there are other ways to turn off gprs too.
Thanx to Caesey for the above info.

 

guys you should try doing the following things to conserve battery life:

1. turn off wifi/gprs when not in use
2. close constantly running applications by installing advanced task killer
3. close animations by going to settings, sound and displays.
4. adjust screen timeout to 15 or 30 seconds to conserve energy.

By doing the following you can dramatically increase the battery life.

 

I get about 2 days use out of a full charge, running a custom Froyo ROM on my Galaxy S. I keep 3G turned off and only activate it when I have a specific need - I've found that helps battery life enormously.

 

There's so--BEBOOP--mething wrong with my bat -- Dun dun dun dun dun.


Actually, I get 6-16 hours, depending on whether or not I'm using the battery to power a spaceship.

 

My battery life is fine.

Did this question really need a new thread though? There are others on battery life already...
