Battery Life
We didn't have time to run through our entire battery life suite, but we do have some relevant results for the two devices. For smartphones, these are our latest web browsing battery life tests:
We regularly load web pages at a fixed interval until the battery dies (all displays are calibrated to 200 nits as always). The differences between this test and our previous one boil down to the amount of network activity and CPU load.
On the network side, we've done a lot more to prevent aggressive browser caching of our web pages. Some caching is important otherwise you end up with a baseband test, but it's clear what we had previously wasn't working. Brian made sure that despite the increased network load, the baseband still had the opportunity to enter its idle state during the course of the benchmark.
We also increased CPU workload along two vectors: we decreased pause time between web page loads and we shifted to full desktop web pages, some of which are very js heavy. The end result is a CPU usage profile that mimics constant, heavy usage beyond just web browsing. Everything you do on your smartphone ends up causing CPU usage peaks - opening applications, navigating around the OS and of course using apps themselves. Our 5th generation web browsing battery life test should map well to more types of smartphone usage, not just idle content consumption of data from web pages.
As always we test across multiple air interfaces (3G, 4G LTE, WiFi), but due to the increased network load we actually find that on a given process technology we see an increase in battery life on faster network connections. The why is quite simple to understand: the faster a page is able to fully render, the quicker all components can drive down to their idle power states.
All Android tests use Chrome and 5GHz WiFi unless otherwise listed.

The Nexus 4 doesn't break any records for 3G battery life, it ends up relatively low on our list - even the Galaxy S 3 manages to do better here on 3G.

WiFi battery life is similar to the Galaxy S 3, but again it's not all that impressive compared to some of the other devices in this list.

没测试完整续航时间
初步测试,只测试了3G/4G/LTE下网页浏览时间和WIFI下网页浏览时间
正常使用还是能用一天吧,如果和传闻一样是2100mah的话 |
