Help Should I replace the battery? Nexus 7 2nd gen

As cool as it looked right out of the box, this tablet is getting me frustrated.
I bought this for my daughter for Christmas to replace her aged Kindle Fire (not even an HD). She barely has any apps on it - Kindle reader, Netflix, Candy Crush, Flappy bird and the ABC station app.
Nothing much more than that if anything.

Battery is wicked horrible. It won't even stay running straight off the AC charger! The battery keeps depleting even when on AC and eventually shuts off because no battery. Yes, this is using the Nexus charger.

Last night I plugged it in to charge after doing a hard shut down. I shut down from the Android OS and then booted up into the recovery screen and did a power off from there. So it was seriously OFF. After 6~8 hours charging the battery only charged up to 16%.
What the heck.

When running on minimal settings and even in safe mode (same thing in normal mode) the Android OS is hogging up 30% battery. Not a single app actively running and all apps that I could manually force power off are off!

This is OS version 4.4.2.

Can this be an OS problem? Or is there something wrong with the hardware so I send it in for repair?
 
First, sorry to hear about your troubles. I'll just shoot a few ideas out and hope one helps....

Have you erased the device and then installed a clean copy of the operating sys?

Battery replacement is a bit challenging, but possible. The problem may not be the battery however. Maybe another portion of the hardware is draining it. Hard choice there.

Have you called the Google nexus phone line? Below is the link to the phone numbers. Sometimes just an honest dad in trouble phone call can yield results.

Good luck,

Dave

Thanks for the replies!

I have not called support yet. I'm still having a go at testing for myself to see where it leads.

Two days ago (several hours later on the day of my original post) I accessed the recovery tool and did a full system reset to factory settings.
I then shut it down and plugged it into the wall.

After 32 hours of charging (this morning) it finally reached 100% battery.
I checked the battery usage and the Android OS was only using about 13%. I refreshed a couple times and the Android OS usage slowly climbed back up to over 30%. Maybe this is normal???

I turned the device on, unplugged it, and have left it to idle.
If it takes a significant drop in 8 hours of idle then I'll be calling support tog et this thing repaired.
hopefully they replace/repair it. I'm not sure where I put the sales receipt from Best Buy :thinking:

So now I'm confused.
It isn't dropping battery hardly at all now.
I set it to run a movie off Netflix last night as I went to bed. I woke up and it had 90% battery left still.
Android OS was now just sipping on power at a low 8%.

Time to drain it to about 70% and see how long it takes to charge back up.
