Battery Level Issues

[Guest Ian1]

Hi,

My Nexus 7 has developed an odd issue with the battery level indicator. Over the last few weeks I have noticed the battery level has been showing an incorrect status, for example after 2 days without charging and moderate use the status was showing more than 50% available. But now all of a sudden it's constantly displaying 100%.

I am wondering if this is just an issue with the battery level indicator or if I have a hardware fault with the charging circuit.

Can somebody recommend a way for me to test my device or reset / re-calibrate the meter?

FYI I have unlocked the boot loader but it is not rooted.
