Really, this should be a no brainer, but I wanted to share how to make your Nexus 5 battery last longer than 24 hours without recharging it.
Under settings, you have an option for mobile networks> preferred network types. You simply un-check LTE and switch to 3G. There is no difference in call quality or phone performance, but it reduces battery drain significantly.
Also, turn off your WiFi radio, and mobile data. Thus also reduces strain on battery life.
Next and final step, is when you are not using your phone, turn the damn thing off and put it away > you have voice mail, txt msgs, email and potentially a hundred other ways that people can leave you messages.
If you need to be constantly talking on a cell phone for work, then the Nexus 5 is not for you, I would suggest a BB, as their batteries are like Tonka Trucks, durable and last long!!!!!
Hope thus helps with your Nexus 5 battery life woes, feel free to leave a comment, I am anxious to see if anybody actually tries this.

Have a great day folks!!!

Welcome to AC.☺

Thank you for your post. It's exactly the sort of thing that will make you all the more welcome as a member....sharing info and tips with others. You may care to head on over to the Google Branded Devices/Nexus 5 forum and see what's going on there.

One tip deserves another....I've never felt the need to use, but the Greenify app is said to be good at improving battery life, should you want to try improving yours still further.

If you turn off mobile data, you have basically a feature phone - no internet connection. If you turn off LTE and leave 3G on, your data speed is much lower (and non-existent already in some spots).

The proper method is turn off anything you're not using. If you're in the car, wifi should be off. How many hots[ots will you be finding on the interstate? If you're at home, with wifi, mobile data should be off. Leave GPS off until you need it. And leave the screen off (and keep it at the dimmest you can use) when you're not using the phone. The screen is the single largest user of battery.

But with all the radios and the screen off, a properly conditioned and fully charged battery should last a couple of days, at least, until the 50% charge point, at which point you should recharge - 40%-60% (see Battery University - How to Prolong Lithium-based Batteries). We're well past the days of 6 hours of standby time on a NiCd battery on a phone. The only reason to turn the phone completely off is if you really won't be using it for a while. Turning it off for an hour won't save much - it takes a lot of battery to restart when you turn it on. If you're leaving it home for a week when you're on vacation, turn it off before you leave. (For those born with a cellphone plugged into your umbilical cords, yes, you CAN live without a cellphone. There are still people alive who can remember when almost no one had a phone at home. We wrote letters or walked to a friend's house.)
