Question about battery usage profile on my S3

[vbidez]

Hello all,

Lately I have consistently noticed that the battery usage on my S3 looks like this (sorry for the crude MS Paint rendering).

So the battery usage will seem relatively normal for most of the time and then suddenly it will drop off a cliff and the charge will plummet from say around 40% to 10% within 30 minutes to an hour.

Is this a problem with the battery? Is it because I haven't been charging and discharging it properly? Do I need to buy a new battery?

Thanks!

You don't need to properly charge and discharge Li-on batteries. It could be an app that is causing the battery issues.

It would be much more useful if you posted actual battery usage screen shots, as shown in this post: http://forums.androidcentral.com/samsung-galaxy-s3/341894-battery-drain.html#post3302876
