Processor and battery
The Overture has a 1.2GHz Qualcomm dual-core processor, which was better than I was expecting. As such, performance was mostly satisfying. The handset started relatively quickly (just suffer through an annoying Aio jingle as the phone powers on), there's barely any shutter lag, and I didn't have to wait for applications to open. The touch interface on the display was responsive, as well. Yes, there are faster phones, but the Overture was quite zippy for a midrange device. In my tests, the Overture had an average Linpack score of 216.140 MFLOPs (single-thread) with a high of 231.367 MFLOPs. On the Quadrant benchmark it has an average score of score of 4,721. For comparison, that's about as fast as 2012's
The 1,780mAh battery has a reported talk time of 9.5 hours and a standby time of 12.5 days. During our battery test for continuous video playback, the Overture lasted 5.52 hours.

Honestly, it wouldn't have shocked me if Aio had left the Overture on 3G, which is why I'm so glad to see that it supports 4G LTE speeds. That connection remained solid and fast throughout my trial period in everything from Web browsing to app downloads. Out of five separate tests in the same location using Ookla's Speedtest.net app, I clocked an average download speed of 7.61Mbps and uploads at 4.89Mbps. The highest upload score was 8.62Mbps and the highest download score was 5.16Mbps. When LTE isn't available, the Overture will fall back to 3G (UMTS 850/1900/2100).
On the default Android browser, the CNET mobile site loaded in 4.53 seconds, the full CNET site loaded in 12.26 seconds, and the full site for American Airlines loaded in 8.59 seconds. The CNET Android app (3.72MB) downloaded in 32.21 seconds and launched with updated content in 12 seconds.
I tested the dual-band (GSM 850/900/1800/1900) ZTE Overture in San Francisco. Remember that as a brand of AT&T, Aio uses AT&T's regular network. Call quality was satisfying on the whole, though it wasn't without a few issues. When calling another cell phone, the signal remained strong and free of static, though some audio had an unnaturally high pitch. It wasn't a big deal, but a couple of my friends didn't quite sound like themselves. The volume level on the Overture could stand to be a bit louder, as well.
On their end, callers had no complaints. One friend specifically mentioned that the Overture didn't pick up any background noise. I also had no trouble using an airline's automated calling system when calling from a quiet office. I was able to walk several steps through a voice command menu without having to repeat myself. Granted, my experience would be less ideal if I tried calling from a noisier place, but that would be the case with any almost other cell phone.

The speakerphone didn't fare as well, unfortunately. Though the volume was loud through the single external speaker, I had to repeat myself occasionally if I spoke from anywhere besides a quiet room. Voices didn't have the same high pitch that I heard on regular calls, but I noticed some distortion in the audio quality. On the whole, it was about average for a cell phone speaker: not really good and not really terrible. The Overture has a maximum SAR of 1.25 watts per kilogram as tested by the FCC. It supports M3 and T4 hearing aids.

As for Aio's other starter smartphones, I'd definitely choose the Overture over the 3G-only
