Welcome to Windows Central.

For the "lock screen", could it be that what you're seeing is the Glance Screen with your custom background image?

Nonetheless, if you're having troubles with your phone (the charging issue) just two days after purchase, you could bring it back to the store where you bought it together with the official receipt and have it replaced.

It does sound like Glance Background is on... Check that in Settings > glance background

Also, try a Soft Reset. Hold the Volume Down + Power buttons until the phone vibrates and reboots (about 10 seconds). You may just be having a small glitch getting the battery to update status...

Finally, try this free App. I find it very useful for analyzing charge and discharge on Windows Phone and, IMHO it offers the best Live Tile info especially on largest tile.

If none of that helps use your warranty as gpobernardo advises.
