Nexus 5: Power and Convergence

  • Hi All,

    Just got a nice and cheap refurbished Nexus 5 and am very much enjoying my first foray into linux on a phone. UBPorts has done a fantastic job keeping this OS alive. Some parts of the user experience are really excellent and unique.

    I have two questions though that I can't seem to find an easy answer to and was hoping you could help:

    1. Power Consumption: What would a typical amount of power consumption be? I'm not sure the exact numbers but if I were to leave the phone fully-charged before going to bed but not connected it would be drained by the time I wake up (6-7 hours later). Yesterday, out and about, it lasted about 3 hours. Is this typical or does it seem like the battery could use replacing? I have a spare battery, just would like to avoid pulling the phone apart right now.

    2. Convergence. What, if anything, do I need to do to get the phone to show up on a screen? I have a usb to HDMI converter (that nicely also allows the power supply to be connected) but when I connect to my screen it doesn't seem to register. Ordinarily would it be automatically seen by the screen or is there a setting I need to change or a more formal dock needed?

    Any help you can give me would be much appreciated.

    Thanks in advance!

  • I have a new Nexus 5 for comparison. My battery lasts 2-3 days if switched off at night so I'd say your battery is just about dead.

    The phone requires a micro USB cable to connect to a computer.

  • Yeah, nearly all N5 need battery replacements these days. But even with a new one don't expect wonders, as battery life was never great with the Nexus5. Still a with a new good quality 3rd party one (too many fake "genuine" ones on the market) it should last you through the day.

    For video out you need a special SlimPort adapter. What you have is probably MHL which will not work with the N5.

  • @eganonoa My battery will drop from 100% to 90% over night, so I think is your battery. You can go so far as buying a phone charger or a stick that will show you how much current your battery draws, do a bit of math and see the real capacity of your battery.

    This is how it looks my battery graph, and I was night shift 🙂

  • @cliffcoggin Thanks. Great. I will definitely put in the spare battery I have.

  • @poVoq Super useful! You are 100% correct, what I have is MHL. Couldn't for the life of my figure it out. Had the external display switch on, tried every HDMI cable I could find around the house. Saved me from going crazy. Thanks!

    LTE is draining battery a lot on the N5, but over wifi (at work and at home) I have about 36 hours from 100% to 19%.
    I switch to flight mode when I'm sleeping 8-9 hours a day.

    About the dock there are some known to work with the N5, IIRC the one recommended is from Microsoft.
    If you intend to buy one I might be able to dig out the info from a Q&A early this year.

    That is for wireless display out (Miracast). But that is IMHO only good for watching movies etc. The lag for regular desktop use is a bit too high.

  • @poVoq Ooops my bad you're right.

  • N5 is presented as "experimenting convergence" on this page :

    So there should be an "how to experiment it" tuto somewhere...

    Thanks all. Changed the battery. Has been run 15 hours since (not in airplane mode but syncing in the background on wifi) and battery is now at 42%. So that's about 26 hours expected with light usage and probably about 2 full days worth if put in airplane mode over night. Really impressive.

  • @eganonoa You could mark this as solved then if your happy. Use Topic Tools ask as question then change to solved. It all helps others find answers. Thanks
