Sorry I meant depth wise. The Droid Maxx is thinner than the Nexus 4 but has a much larger battery.
I would've liked to see a bit larger capacity battery but realistically, didn't expect it to approach the Maxx or any of the larger devices with 3000+ mAh. Matching what's in the S4 (2600 mAh) would've been nice but considering it appears to be smaller, 2300 mAh seems alright. The HTC One only has 2300 mAh and while it's no Droid Maxx, it serves me well enough and I'm a moderate to heavy user.
