: Battery woes - Battery completely discharging during the night

I charged by phone to 100% before going to to bed last night, at some point during the night the battery managed to completely discharge itself. I use my phone as my alarm clock, so i was very lucky to get to work on time, as my alarm never went off.

Is anyone else having similar issues with there Galaxy S?

I am running the following stock loadware (if that makes any diference)

I9000XXXF1

I checked on app killer that no GPS apps, or the WI-FI was switched on before going to bed, so I am at a loss to explain sudden battery death.

I have read through the battery life forum, and had already implemented many of the reccomendations.

Any help will be appreciated, if the battery keeps discharging, then the phone goes back to the shop.

The only thing I can think is you must have had some a lot of applications open. Remember it has multitasking so close all applications before you go to sleep and the battery should be fine. Also try putting it into flightmode. Maybe where the
phone is place when you sleep has low signal strength? Or the phone is constantly searching for 3G. Flight mode would stop this.

Have you happened to use Wifi Tethering? There is a bug for 2.1 when you started using Tethering, it will start draining your battery even if you turn it off, the only way to stop it is to reboot phone.

Thaks for the updates. I did check my runnig programmes before going to bed, and there was nothing battery intensive. I will try the flight mode and see if that makes any difference.

On the second day I had the phone. I had an issue where the phone got very warm, and the battery just driained away. I will give the phone one more chance, if it discharges again, I will take it back with a fault.

I had an IPAQ PDA (back in the day) which used to do something similar, the unit would get warm, and the battery would just discharge. No ryhme nor reason, just because it could. (That cuased no end of swearing)

I know this is cumbersome, but could you provide us with a list of everything you have installed on your phone, and also which widgets you are using on your desktops?

Then we could weed out which apps/widgets could be causing this and you could try uninstalling those apps and widgets to find the culprit.

And also, if you have a task killer that kills tasks automatically, this might be the root of your problem because Android will keep reloading tasks and the task killer will keep killing them, resulting in many unnecessary processor cycles and leading to battery drain.

Yes i think automatic task killers are a waste of time,just use the ones that tweak androids built in task killers settings ie minfreemanager and autokiller

Kill apps. Turn off sync and switch to 2G. I lost just 1% battery all day while I was asleep and still recieved texts etc :) (working nights)

Thanks for all your replies. It looks like it was the application killer that murdered my battery. After reading the responses, I removed the advance app killer application. Charged the phone before going to sleep last night, and this morning, the battery monitor was showing a nice healthy battery (about 90%), but that was with 3G switched on.

The battery on the Samsung does not seem to be as good as my old Iphone 3G, but this may be because I am playing with the phone more, as the SGS screen is just fantastic, the colours are so vibrant.

It's actually better than the Iphone 3G but it takes quite a few charge/discharge cycles to get there and as you said, you are playing with your phone a lot when it's new. Be patient and you will love the battery life compared to your Iphone 3G eventually.
