Are You Experiencing Extreme Battery Drain Problems on your Nexus 7 3G?

It was brought to our attention by a reader, that the 3G version of the Nexus 7 is currently suffering from an extreme battery drain problem. In fact, some users are reporting that they are seeing up to 8% battery drain per hour, on standby. Now that to me is a huge problem. That means your tablet might be dead before your phone is. This issue has been reported to Google, but so far they haven’t done anything about it. It was first reported on January 20th. Which means Google had time to fix this in the Android 4.2.2 update, or even get it working for Android 4.2.3 and get that pushed out.

Another user has chimed in on the thread, that selecting their network operator instead of leaving it as automatic has reduced the battery drain that the wakelock causes. Of course, this is only a temporary fix, and we still need Google to do something about it. The wakelock in question here is baseband_xmm_power. It appears that instead of going into deep sleep, hence the wakelock, it’s sticking to the 51MHz state. Which isn’t to bad, but it’s still using much more battery than if it were in deep sleep.

Many users are getting frustrated because Google has not stated anything about fixing it, or even a solution to fix it. The wakelock was present in Android 4.2.1, and continues to be present in Android 4.2.2. You probably remember all the issues that were part of Android 4.2 on the Nexus 4, Nexus 7, and Nexus 10 when it first came out. Well since then most of the issues have been solved, but there are still a few left, including this one.

How many of you own the Nexus 7 3G? And how many of you have noticed this wakelock issue on your device? Anyone else noticing other bugs in Android 4.2.2? Let us know in the comments below.
