    Thumbs up My Nexus 7 turned into a perpetual motion device!

    Have you ever seen a battery graph like this?

    This is after 40 minutes of light web browsing while listening to music. Awesome, isn't it?

    The detailed view indicates that the display was never active:

    Btw, the device was completely shut off over night while being charged with the official wall charger.

    It just shows why people should not put too much faith in those graphs. It is all an estimate of power usage and remaining charge.

    Das ist ausgezeichnet! Google wird dieses Gerät von Ihnen zu kaufen, so dass Sie ein reicher Mann, und schon bald haben wir alle Geräte, die nicht aufgeladen benötigen!

    I have seen similar on my note 3. About 30 minutes screen on at 1%. Your battery may need to be calibrated.

    True, but I always found Android's battery monitor to be quite precise. Now, this is way off and I wonder what triggered it. I didn't install any new apps or something like that.

    Nice!
    I could definitely use some krautfunding. *slaps knee*

    Is that even possible/necessary with modern batteries? I simply connected my Nexus to the charger while being turned on and everything is back to normal for the time being.

    It made a difference on my note 3. After a full drain and recharge, it was showing accurate usage again.
