Like the Lumia 920 before it, the Lumia 928 features a 2000mAh rechargeable battery within, which cannot be removed or swapped. That might sound like a fair bit of juice in tow, but curiously, it continually fell short in our usage.
With consistent use during the day, including a mix of email checking, web browsing, and playing games, we were seeing the "battery is critically low" warning well before it was time to retire. Power users sadly won't be able to get through a full day with the Lumia 928 unless they turn down the brightness and utilize power saving settings, but where's the fun in that?
Even Nokia's battery life ratings seem low on paper, with 6.3 hours estimated for cellular browsing time and the same listed for video playback. Of course, it's rare that you'll do just one thing with the Lumia 928 for that long of a span, but as we utilized different apps and functionality – and not even at a constant clip – we found that the device rarely extended into evening without an additional charge.
The Lumia 928 does have built-in wireless charging capabilities, however, making it easy to top off a bit – assuming you shell out for the charging pad, of course.
Connectivity
Like its brethren, the Lumia 928 features a wide array of connectivity options beyond its 4G LTE cellular service, including dual-band Wi-Fi a/b/g/n, Bluetooth 3.0, DLNA, and NFC support, with everything accessed (unfortunately) by digging around the Settings menu.
Getting content on and off of the device is a pretty straightforward process, luckily. On PC, you can drag and drop from the folder as desired, while on Mac, a free Windows Phone application is used for all content transfers.
