We mentioned in the design section of the review how Google was able to drastically reduce the overall volume of the tablet. That came at the natural expense of the battery, which now measures 3950mAh. Under everyday use, I found little to no difference between the new and old Nexus 7. Of course, your mileage will vary drastically depending on how you use it. For me with moderate use I got over 48 hours. This was with Wi-Fi on all the time.
However, the 400mAh reduction in addition to the far more power hungry screen will naturally take its toll. When gaming I found the battery to drain at about 25% per hour, a considerably higher rate than I was expecting.
The following battery test was conducted by playing a 1080p movie with 50% brightness.
Recently we’ve been hearing stories about users complaining about the GPS performance on their new Nexus 7. The problem arises when the GPS has been active for about half an hour, after which it would stop locking onto a satellite no matter what you do. We found no such issue on our unit. GPS performance was as good as any high-end smartphone.
The Wi-Fi stack on the new Nexus 7 has been improved from the older version. It now supports dual band 2.4 and 5GHz with 802.11a/b/g/n. The inclusion of the 5GHz band makes a huge difference in situations where 2.4GHz is congested. We found the signal range on the new Nexus 7 to be quite acceptable, in line with the iPad 4.
The following Wi-Fi test was conducted using iPref on a 5GHz 802.11n network.
