I love my Galaxy S Android Phone's Battery Life!

At Technoracle, we regularly test out devices for long term reliability, performance, and durability.  Mobile devices often vary dramatically from the manufacturer's claims and real world tests reveal the true nature of a specific device.  For example, some smartphones have claimed 4-day standby time.  No device I have ever used has ever met such a claim while we were using it.  Most users we know are happy to get 24 hrs out of their devices with real world uses.

Four days of use from a single charge might be possible if you disabled all functions other than sitting idle and left the phone in a cool room with no magnetic interference.  For most users, add in email account monitoring, some web browsing, navigation and a few calls and the time goes down significantly.  The major reason I went from iOS to Android is that I hated the idea of someone sealing my battery into the phone.  I want two batteries and the ability to swap them out as they get tired. Nevertheless, the Samsung Galaxy S has amazed.

The above screenshot clearly shows that the Samsung Galaxy S smartphone has amazing battery life very close to what the manufacturer claims.  The approximate 65% charge is after 1 day 3+ hours between charges with cell standby and use.  What I have noted is the following tips work well on Android for saving battery life:

1. Reduce screen brightness.  Do this manually.  The auto-detection itself uses energy when woken up.
2. Configure email not to push automatically or synch.  Do this manually.  What point is there for you to have email pushed to you that you will not read?  Wait until you want it, then fetch it.
3. Disable GPS when not in use.
4. Disable Bluetooth when not using.
5. Regularly check the application and memory manager and clean out programs that you are not actively using.
6. Disable notifications from applications (Twitter, Facebook, news, weather, etc.) that you do not need.  When I go on my boat, I do require that severe weather be pushed to me.
7. Disable auto-orientation.  The listener that detects position changes runs the accelerometer, a piece of hardware that consumes battery life.  Luckily the feature can be disabled from the pull down menu.

End result?  


  1. You forgot to add: don't talk on the phone. Don't use any data services.

    I love this device, I WANT to. But I can't get half a day of normal use without using all your listed tricks. Makes me a bit sad.

  2. Just thought I'd add that I get excellent battery life on my Galaxy S as well (T-mobile Vibrant flavor). After playing around quite a bit with the settings and watching apps very closely for the first few weeks I had it (using the excellent SystemPanel app) I found the big battery suckers and have been very satisfied ever since. Easily twice the battery life of my old G1. The Facebook app was a killer until I turned off push notices, but the worst app, by far, that I've run into yet was Winamp for Android. Most of the time I could go two days without a charge, but since I don't want to cut it close, I just plug in each night, and I never even have to think about mid-day charging anymore.
