The Nexus 7 is an awesome device. However there are a few problems that might be little fun killers. My N7 is affected by one of them. In correspondence with ASUS I managed to fix this little issue:
My Nexus 7 shuts down at about 10 % - 20 % battery. It should however shut down at approx. 1-3 % at least, my Galaxy Nexus even goes down to 1 %. Initially I fully charged it. On the image above, you can see that it drops to 0 %, dying suddenly. Moreover you have to plug it in and press the power button at least 20-30 seconds to boot it up again. As you can see, I tried again, however it died again.
- Fully charge you device to 100 % and wait at least two more hours
- Unplug the device
- Perform a Factory Reset and wipe all the data
- After the set-up, plug in your device again
- Wait for about one hour and unplug the device again
- Use the device until it goes to about 15 % (or your former shut-down level)
- Do not use it until it gets down to about 2 - 4 %, check the battery every hour or two
- If you reach the 2-4 %, well, plug in the charger again, your problem seems to be fixed
If it doesn't help, you will have to request a replacement. Currently my device works fine.
Read on... In my correspondence with ASUS, I ask how to charge the battery correctly.
