I have had to charge the Google Nexus 5 every day since I started using it. Starting out with a full battery it's generally 30% or below by the end of the day, and for really heavy usage days it needed a top-up before bedtime.
Now, there isn't really any such thing as "normal" usage, but it would be fair to say that I'm a heavy user. I take my phone everywhere and use it frequently. I left Wi-Fi and mobile data on at all times, enabled location tracking with high accuracy, and opted into Google Now.
A typical day will include a cumulative hour of gaming, maybe 90 minutes worth of web browsing, a couple of photos, and a smattering of app action in Facebook, eBay, Twitter, and Flipboard, not to mention obsessive email checks (even with it set to a 15 minute refresh rate).
What this reveals, beyond my worrying smartphone addiction, is that the Nexus 5 is fairly typical.
Initially the battery life is very erratic, but this is no cause for concern, because you should find that it settles down after the first few days. Remember that downloading and installing a burst of apps tends to eat the battery life fast.
Downloading and installing an exceptionally large game, such as Asphalt 8: Airborne, which is 1.6GB, using Wi-Fi actually ate a staggering 10% of my battery.
If you use the Nexus 5 to navigate with turn-by-turn directions or play a graphically intensive game, like the aforementioned, Asphalt 8 then you will really notice a major drain.
The Nexus 5 battery dropped 3% in ten minutes of gaming. Streaming a 55 minute episode of Breaking Bad through Netflix ate 20% of the remaining battery life. A 15 minute call drained just 2% away.
I should also point out that my home is outside 4G range, so if you've got LTE coverage that could drain the juice faster. On days when I was able to get an LTE connection I didn't notice a major difference, but your mileage may vary.
The Nexus 5 battery is rated at 2,300mAh, a bit lower than the Galaxy S4's 2,600mAh battery.
Our 90 minute video NyanGareth battery test, with the screen at full brightness, knocked the Nexus 5 from fully-charged down to 74%.
The good news is that the Nexus 5's battery life could be set to get better. Project Volta, an aspect of Android Lollipop, gives detailed stats on what's killing your battery, while a new battery saver mode should help you eke extra juice out of it.
But even without that Android 5.0 should be more battery efficient, as in a test ArsTechnica found that a Nexus 5 running Android Lollipop gained roughly 36% extra battery life.
Inside or outside, in a busy shop, or a deserted street, the Nexus 5 made and received calls with no problems. Callers reported my dulcet tones came through loud and clear, even with my four year-old son screaming in the background, which points to some good noise cancellation skills.
I also found callers came through with plenty of volume and clarity on my end. The speakerphone isn't as clear, but it does the job.
The phone app has been overhauled again in Android 4.4.4 and it's very convenient to use. The last call is listed at the top and then you get big contact spaces for your most frequently contacted friends and family. As with so much else expect this to get a new look with Android 5.0.
When you do need to call a more distant contact you can just type in the search bar at the top and you'll rarely have to enter more than a couple of letters before they pop up.
You can also search for local businesses in here and call them directly, which can be very handy when you need a pizza at short notice.
I love the keyboard on the Nexus 5. Google has definitely made improvements, because for the first few days I would pause after a staccato burst of typing to go back and make corrections, only to find that the text was error-free. The swiping option has also been improved, making one-handed typing much easier.
The purity of the Google experience on offer here is unmatched anywhere else. Cast an eye over the pre-installed apps, from Maps to Hangouts, from Gmail to Quickoffice, from the Chrome browser to YouTube, the strength of the Google ecosystem is impressive.
Swipe to the right on the home screen and there's Google Now, ready to serve. The Nexus 5 offers everything that's good about Google in a streamlined format.
I can't move on without discussing the newly merged Hangouts app, which puts Google's chat messenger together with your standard text messaging.
It means you have one port of call for chatting to friends and family via text (assuming you use Hangouts).
Text message threads have now been merged with your instant messaging threads in Android 4.4.4, and there's a clever auto-detect so you don't have to manually choose your method. It's good to see integration generally, especially when it reduces the number of apps you need on your phone.
