The Nexus 6 also has a larger 3,220 mAh battery compared to the Nexus 5's 2,300 mAh unit, but it also has a larger display to juice up.
The upgrades are undeniable, but pricing usually plays a big role in decisions as well. While the Nexus 5 aimed to combine power with affordability, the Nexus 6 comes at the top end and carries a premium price tag to match.
If you need something more than a smartphone, the Nexus lineup has you covered as well.
The latest Nexus 9 tablet, made in collaboration with HTC, is a powerful slate able to handle virtually any task you throw at it. Launching to replace the previous Nexus 7 and Nexus 10 in one shot, the Nexus 9 comes with an 8.9-inch display with a 4:3 aspect ratio and a 2048 x 1536 pixel resolution. Under the hood, the tablet packs a 64-bit NVIDIA Tegra K1 processor running at 2.3GHz, 192-core Kepler graphics and 2GB of RAM.
The Nexus 9 further features an 8-megapixel rear camera, a 1.6-megapixel front camera, optional LTE connectivity and NFC. Users can also attach an optional Keyboard Folio case via NFC and get extra battery life, as well as a laptop-like experience.
The choices are there, so ultimately, it all comes down to ones needs, preferences and possibilities. Google is no longer selling the Nexus 5, but interested customers can still find the smartphone at various retailers.
