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.

    Motorola is a Google company now no matter how they try to pretend otherwise with the whole firewall between them nonsense. I'd see how they do now. Meanwhile Google payed an idiotic sum for Motorola to get a bunch of worthless patents and is left trying to save face by still producing phones.

    O hai appletard! Nice to see you still have a brain, somewhere.

    Just as a small update, 4.4.2 started rolling out for the Moto G today...
  • InvaderC1 - Saturday, December 21, 2013 - link

    Moto G already had 4.4.2 shipped, and Moto X was first non-nexus device with Kit Kat. Since being bought by Google, they have turned thing around, at least with this first wave.

    Well moto g already got 4.4.2 a couple days ago. http://www.xda-developers.com/android/android-4-4-...
    And it has been said by motorola that the RAZR HD will as well get 4.4 soon.
    Besides, taking into count that motorola has already got 5 devices running on 4.4 (Moto x, moto g, Droid ultra, maxx and mini) while other manufacturers haven't got 4.4 not even in their flagship talks really, REALLY well of their new update policy.
    P.s: Old Razr (xt910) released on 2011, worst time ever for motorola, still went from 2.3 to 4.0 and from there to 4.1. Just for you to keep it in mind :)
    p.s.s: Yeah, i do know that the atrix family as well as milestone didn't have the same luck, but luckily for us, they seem to have changed, for good.

    Thumbs up for not using the prefab line from what I must assume is a google/moto payoff presskit "Moto G, simply the best phone under $200"

    Thumbs down for no comparison with the Lumia 520/521 that have been dipping down into the $50 range off contract.

    Damned good phone considering the price point. No, even compared to quite a few more expensive ones. Absolutely impressive battery life, a camera that doesn't suck and at least as fast as the last generation of top-end phones, all in a nice package and for very little money. Well done, Motorola.

    A lot of phone for the money. I bought a 16GB model and will be giving it to my daughter for Christmas. She wanted good battery life, good display, and stock Android if possible. I would say the Moto G delivers all three.

    "The Moto G’s goal is pretty simple – to deliver an affordable smartphone experience that doesn’t make any sacrifices"

    I'd say that a maximum of 16gb of memory is a pretty big compromise. Because of those, about 12 will be available to the user, and out of those 12, at least 1 or 2 will be gone in stupid gallery thumbnails hidden files. Add 3-4 gb of music, and 2 or 3 heavy games, and you are left with less than 2 gb of free space. If you want to record videos, capture photos, or download movies, you are really screwed. And this is not a poweruser scenario at all.
