Nexus 7 battery bug reported by multiple users
Users of Google Nexus 7 tablets released back in 2013 have been facing a series of battery-related bugs ever since the slate arrived on the market loaded with Android 4.2 Jelly Bean, mainly random shut downs. Despite these rather serious issues, Nexus 7 has been considered one of the best tablets on the market but even the recent update to Android 4.4.2 KitKat did not succeed to iron out all the bugs.
More than these "random deaths" reported by more Nexus 7 users, there were also complaints regarding the charging time of the battery. Tablets affected by this issue need up to eight hours to fully recharge the battery, up from a standard recharging time of about two hours and a half. Fortunately for some, this could be a charger-related problem, as one Google Help Center article clearly shows: "If your tablet isn't charging properly, make sure that you're using the charger that came with your Nexus 7 tablet. The Nexus 7 (2013) charger is rated at 1.35A, and the Nexus 7 (2012) charger is rated at 2A."
While Google works on fixing these problems, it seems the best workaround for the time being is to use a custom ROM based on Android 4.3. According to AndroidOrigin, even the stock Android 4.3 Jelly Bean firmware can help with the charging issue. Remains to be seen how long will it take for Google to come up with a real fix for it, not to mention the older random shut down problem.
