Why is my battery draining so fast even when not in use?

[Nico Van Rooyen1]

Good day,I have a samsung s5 mini. I've had it for almost for a year. The battery life was very good until a few days ago. It suddenly started draining very fast even when I'm not using it. Last night I switched off the mobile data before I went to bed. The battery life was more than 70%. This morning the battery was completely drained. I've also noticed that my phone is slower that usual. And even after I've read a message it still shows that there is an unread message,email and text. Please help.

Welcome to the forums. Have you tried rebooting the device?

Gsam battery monitor, will tell you if you have a rogue app, ect.

I have the same problem and I have rebooted several times. Doesn't help. GSAM battery monitor doesn't reveal any rogue app etc.

Attempting to factory reset, but cannot seem to backup the device using Smart Switch (attempt took 24 hours...still says 0% although it got past "lists" to "Contacts").

Any other ideas? Gratefully appreciated.

Let me revise that. GSAM didn't give much of any info last night. However, tonight it shows battery is depleting at 1% every 2 minutes....
And it now tells me that something called "Media" is using up more than 50% of the battery usage.
Very strange since I don't do and social media (and precious little media of any kind).
It gives an App UID as 10044.
Included Packages include Download manager and Media Storage. And Included Proesses android. process.media

Any idea what any of these things are, whether I might actually need them, and how I could get rid of them?

Oh yes, and it never sleeps and is often hot to touch.

I'd do a virus scan, Malwarebytes is a great option. If nothing shows on the virus scan, it could be a faulty battery. Also I recommend downloading Advanced task killer, you might have a lot of apps in the background that you aren't aware of.

When Media or Mediaserver are using a lot of battery, it's often due to a corrupt media file. This happens because the system's Media Scanner gets stuck trying to scan that file, which makes it work overtime, which uses power. If you have an SD card with media on it, Unmount it (in Settings>Storage), remove it, and insert it in your computer's SD reader. Then run chkdsk to see if it finds any bad sectors: http://forums.androidcentral.com/am...guide-using-chkdsk-fix-corrupted-sd-card.html. Also see if the phone's battery still runs down quickly with the SD card out.

It's possible for a corrupt media file to be on Internal Storage as well, but it's more likely on an SD card, since SD cards are inherently less reliable and more prone to corruption than onboard memory.

I don't think a 3rd party task killer app will be that helpful, because apps in the background should be paused and using minimal battery, unless they're malfunctioning (or up to no good).
