Are you wondering why your cellphone battery power drains fast? Well, there are several things that are causing it. It maybe the applications that are running in the background, playing music/videos and the most taken-for-granted one, Network Mode.
So there are several things you can do to save battery power.
Install a Software to Close Background Apps That are Not in Use
There are softwares out there that are compatible to your phones that can manage your background apps and close them when not in use. For Symbian s60v5, I am using Ramblow. On Ramblow, you can select apps that you can protect, which means it’ll not be closed when Ram flushing is done.
Lower the Music Volume
This is something I’ve noticed, the lower the volume is, the longer your battery life will be. Or just get a separate music player, don’t use your phone as a music player.
Turn Your Network Mode to GSM Only
If you aren’t using the mobile internet (3G), turn it off or on Symbian phones, set your phones to GSM only mode. I don’t know how to set it on other phones but I have two examples to give you.
Nokia 5800 XpressMusic (Just follow these steps). This would be similar to any other versions of Nokia phones except Windows Mobile phones that Nokia is releasing now:





Sony Ericsson j210i. This would be also similar to any other Sony Ericsson phones except for Android versions:



That’s it. You’ll notice that your battery life would be much longer than the usual. But if you need mobile internet, turn it back to dual mode. Hope this helps!
