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.

    And that was a red herring. Did you even read the part where Google themselves updated it past 18 months with 4.3?

    Or would you think them saying "We can't update it because TI no longer has their OMAP team" would make sense to anyone?

    I don't think that you know what a red herring is.
  • sprockkets - Thursday, December 19, 2013 - link

    I absolutely do.

    You're not using the term correctly.

    After being stuck and miserable with a buggy and heavily skinned version of 2.3.4 on my Motorola Droid X2 for 2 years, that's why I finally went for the Nexus 5 this time around (and no more 2-year contracts, either...) I've sworn to never buy another Motorola POS ever again, but I might reconsider if Google's ownership results in major changes... (so far, I'm not seeing that yet)

    You haven't seen major changes? Well sir you need a couple of new glasses.
    Moto x is only device which actually cares about user experience, making life easier for their owners with its unique features.
    Moto g is TOTALLY a game changing device (worldwide) due its amazing price-quality relationship.
    Same goes for the updates, motorola has got 5 devices on 4.4 while other manufacturers haven't even got it yet for their flagship.

    If you care about updates, don't get anything besides an iPhone. Simple as that.
  • ESC2000 - Monday, December 30, 2013 - link

    Yeah but then you have to use an iphone

    The only phone maker with long term update support is Apple. On the Android side you are still lucky to get *A* update with most phones. The Nexus will get you the most, but not anywhere close to what Apple offers in terms of hardware support (Currently 3 generations back for iOS7).
  • sprockkets - Wednesday, December 18, 2013 - link

    Moto X is already on 4.4, before even the Nexus 4.

    This isn't your old Motorola here.

    Oh and btw, the current and former generation of Droids are all getting 4.4.
