Battery onboard mobile devices remains one of the biggest concerns for shoppers, and even in a mass market device like the Moto G it’s an important axis. Although Moto G has a removable back door, the battery isn’t designed to be user accessible and is sealed inside, there’s a sticker which pretty much explains the situation.

Inside, the Moto G has a 2070 mAh, 3.8V battery for a capacity of 7.9 watt hours. It loses the stacked 3D structure that was a highlight feature of the Moto X, but still is a relatively large battery for a device with a 4.5 inch LCD display.

To evaluate battery life we turn to our battery life testing suite, which we run over WiFi and all the cellular interfaces appropriate for the device. Here we see a good combination of regular spikes in CPU usage with idle time, hopefully simulating constant, reasonably paced usage. As always the display is set to exactly 200 nits and configured the same way we always configure devices for maximum consistency.

AT Smartphone Bench 2013: Web Browsing Battery Life (3G/2G)

The Moto G starts out with an impressive result on 3G. There’s no LTE on the Moto G so we’re only looking at the subset of devices that I’ve tested on 3G with the new battery life test. Still it’s impressive that the Moto G can crank out just over 7.5 hours on here, considerably more than Moto X forced onto 3G.

The WiFi test opens up considerable more comparison points, and here I’m really impressed by what the Moto G is able to crank out.

Cellular Talk Time

Cellular talk time is self explanatory, and again the Moto G winds up with an impressive result. I remember when Motorola seemed to somehow always be able to dominate the call test, Moto G definitely reminds me of those days.

Compared to the Moto X, the WiFi and 3G battery life tests really wind up being a story of the power consumption tradeoffs between LCD and AMOLED that remain to this day. The display size to battery capacity ratio is pretty big with the Moto G, and of course there are further improvements to overall efficiency with the latest Qualcomm silicon and modem block inside.

Device Charge Time - 0 to 100 Percent

I mentioned that the Moto G doesn’t come with a charger in the box, a choice which cuts down on cost and is starting to make a lot of sense give the ubiquity of cheap USB chargers.

Thankfully Moto G seems to be good about its charge signaling, as it can pull up to 2 amps on appropriate chargers. The Moto G seems to be compliant with BC 1.2, and seems well behaved with drawing whatever is appropriate from other chargers as well.

    HTC Desire 300/500/600 models are intended to the same market niche.

    I'd have even greater doubts when it comes to Motorola's promises. They've eft their previous flagship customers in the cold, as the RAZR HD is still on Android 4.1 and with no indications of ever being updated. The phone was out several months AFTER Google's acquisition, and it compares horrible with the treatment that Samsung and HTC's customers got.

    Really, Motorola has been promising updates generation after generation, and never shipping them. Do not trust them, you'll get burned.

    Jelly Bean doesn't need a update that badly.

    But I guess you can't blame Qualcomm for it since the S3 is already on Android 4.3.

    The local version that I have of the RAZR HD has several major bugs. At least a revision to 4.1 would be needed.

    Notice that Googlerola has provided ZERO updates for the RAZR HD in terms of providing updates not available prior to the launch (as was the case with 4.1).

    Actually, I wold consider any android pre-4.4 (and thus not having pre-compilation) as completely obsolete.

    RAZR HD is officialy supported by CyanogenMod, and CM 10.1 stable is available for it.

    If you care about updates, don't get anything besides a Nexus. Simple as that.
  • uhuznaa - Wednesday, December 18, 2013 - link

    And even then you can stop caring 18 months later.

    Referring to the Galaxy Nexus? Guess what? The 18 month thing is a red herring.

    Google has updated all their phones longer than 18 months. That also *includes* the Gnex. That's right, it got 4.3 *19 months* into its life.

    TI dissolved its OMAP team. No one can update the drivers for it anymore.

    Still won't believe me? Google is replacing free of charge all 1st gen google glasses because it can't be updated. It also uses OMAP.

    It's Google who said that it will support Nexus phones for 18 months, not me.
