Before we start talking benchmark numbers, let’s mention Wlan performance. The 802.11ac wireless performed flawlessly and on our office 100Mbit connection it managed to connect between 292 Mbits and maximal 433Mbits. Translated in real life performance we got a maximum of 98.82 Mbits out of a 100 Mbit connection, which is an excellent score. With 4G will work as fast as your network provider lets it, but this will heavily depend on the provider and infrastructure. Even 3G internet was sufficient for decent surifing on the phone.
Let’s talk about battery life. As you can imagine the 2300mAh battery should be enough for a whole day of work. This will include a few phone calls, lots of texting, browsing, GPS use, basically the usual day in the life of a smartphone. Naturally if you play Dead Trigger 2 for a few hours, you will bleed the battery dry, but this applies to any phone on the market. With normal use the 2300mAh battery should provide enough juice to last from early morning to the late night. With modern 4 to 5-inch phones, we do recommend that you have an extra charger at work, in your car, or an external battery pack as it’s possible to wear out a battery in a few hours of extensive use.
The performance was better than what should be expected from a $349 mainstream phone.
In Antutu 4 the Nexus 5 does just fine against much more expensive competitors like the HTC One Google edition with Android 4.3 and it practically ties with the Snapdragon 600 powered Galaxy S4. As we can expect it runs significantly faster than the Nexus 4, which was plagued by throttling issues.
Nexus 5 dominates in Geekbench 3.0 leaving the more expensive competition in the dust.
Again Nexus 5 takes the lead in Java intensive SunSpider test running it two times faster than Nexus 4. We believe that Nexus 4 users will notice a big difference in browsing speed especially in Java intensive pages.
In Quadrant Galaxy S4 and HTC One are faster, but the Nexus 5 is much faster than its predecessor.
In CFBench and Vellamo 2 HTML5 test the Nexus 5 is faster than all competitors.
3Dmark Ice Storm maxes out in Ice Storm and Ice Storm Extreme. In Ice Storm Unlimited the power of Adreno 330 results in significantly faster performance than Adreno 320 based devices like the Samsung Galaxy S4 and HTC One. This shows that Nexus 5 is fit for modern games and the new ones to come.
In GFX Bench T Rex HD we tested only the off-screen test to see the maximum of frames we can get with Adreno 330 based Nexus 5 and we scored 43 percent faster than the closer competitor.
The domination continues in Egypt HD the as the Nexus 5 scores 42.5 percent faster than Galaxy S4 and 46 percent faster than HTC One Google Edition. The old Nexus 4 powered by Adreno 320 GPU ends 72 percent slower than Adreno 330 based Nexus 5. The old Adreno 320 reaches its limits fast, especially in this test. Overall one can expect that Nexus 5 can get smooth performance in today's top games.
To sum up, Google’s Nexus 5 is one of the fastest phones on the market and performance is not an issue in everyday work.
