Alcatel Idol 3 (5.5) features a 5.5" FullHD (1920 x 1080 pixels) IPS display. The unit has the same size and 401ppi pixel density as the iPhone 6 Plus. The 4.7" Idol 3 does away with 720p display with 312ppi.

The manufacturer boasts that the classy screen comes with dynamic color and contrast adjustment. They are marketing as some Technicolor technology but the truth is only licensing its brand to the smartphone maker and whatever technology they have, it has been developed in-house. The enhancement in this case refers to dynamic boosting of colors and contrast of certain areas of the classy screen image so that skin tones and faces remain natural looking.

One thing is certain, both phones have pretty nice displays for their price ranges and we really like the side viewing angles, the colors and the contrast. Sunlight legibility is quite fine on both models.

Battery life

Alcatel Idol 3 (5.5) packs a 2,910mAh non-removable battery. The unit's power similar to that offered by some of the device's rivals in the mid-range segment. We put the Idol 3 (5.5) through the paces of our battery test. It achieved an endurance rating of 67h, which is quite good.

The Alcatel Idol 3 (4.7) has a significantly lower power battery of 2,000mAh. The unit propelled the device to an endurance rating of 55h.

Regarding the wide gap in talk time, you should bear in mind that the Alcatel Idol 3 (5.5) has been tested on a T-Mobile US network (3G mode) far from our usual European test site. This is one potential reason for the huge incompatibility though our experience with other smartphones is that as long as the network signal is good, the choice of network cannot influence the battery life score that much. This should come to point out that, we're most probably looking at a genuine incompatibility in the performance of the two, which can be caused not only by battery power but also due to a incompatibility in the modem used by the built-in chipset.

Our endurance rating is an approximation of what the battery would theoretically last you if you were to utilize your phone for an hour each of telephony, web browsing, and video playback per day. While usage routines certainly vary, we've adopted this as a basis of our calculations to allow you to compare the real-life battery life of the phones we review. The endurance rating calculation also includes a standby battery draw measurement, which is not shown on the scorecards above.


The Idol 3 offers a rich set of connectivity features. The basics include quad-band Global System for Mobile communication (GSM) and UMTS, followed by HSPA+ and Cat. 4 LTE (150Mbps) support. Certain markets also acquire a Dual SIM model.

A slight incompatibility between the two Idol 3 models in the connectivity department means the 5.5-incher had dual-band Wireless Fidelity (Wi-Fi) a/b/g/n support and Bluetooth 4.1, while the smaller 4.7-incher relies only on single band Wireless Fidelity (Wi-Fi) and Bluetooth 4.1.

Other than that Wireless Fidelity (Wi-Fi) Direct and Wireless Fidelity (Wi-Fi) Display are supported by both devices, as well as NFC. Both have GPS receivers too and Universal Serial Bus (USB) On-The-Go support.

The only notable lacking features here could be a wired TV-out option, though the significance of its lack will vary depending on your utilize case.
