    I just bought a certified refurbished Nokia Icon as my old 928 was only its last legs (battery wasn't holding a charge, power button would randomly trigger and hold, and my non-speaker phone earpiece would have connection issues) (I would have loved a more modern phone, but Verizon doesn't offer much). I have updated the Icon straight to Windows 10, but I'm noticing huge battery drains. My first go with the phone yesterday lasted about 6 hours on battery with light use (mainly texting, using OneNote for grocery shopping). Anyone else having a problem with battery drain? I've noticed that Aida64 is reporting discharge rates of ~1000 mW-1500 mW on battery. Aida64 also shows that my fully charged capacity matches my designed capacity, so I think the refurbishers put in a new battery before sending it to me? Today I've disabled more background tasks, as well as Hey Cortana. I have also adjusted the screen brightness in Extras, so we will see if that has improved battery life.

    My current Windows version is 10.0.14393.189. Does anyone think this is a problem specific to the Icon I received, a general Icon problem, or a Windows 10 problem?

    By the way, I should probably note that this was a new refurbished Icon; I am kind of wondering if I should have bought a brand new Icon.

    My Lumia 930 ( same basic phone ) even with a brand new OE Nokia battery installed struggles to get 16 hours when running Windows 10. The Lumia 930 battery life is better on Windows 8.1. To be fair Lumia 930 / Icon battery life has never really been great.

    Lee, thanks for the info. I would be very happy with 16 hours. My current tweaks haven't pushed the battery life much further--I am thinking about sending the phone back and getting a new (instead of refurbished model). Aida64 reports higher drain at times, in the 2000-3000 mW range, which just seems crazy.

    I have the same issue. I would get nearly 24 hours with light usage, sometimes much more without issue. However, I finally hooked onto the AU (.67) and the phone would get hot.. very hot .. while the battery drained quickly. With the update to .189, it seemed to have improved (at least in idle), however, it is still quite disappointing. I typically have my unit on my wireless charger at work or at home. On very light usage, I can get 12 hours .. again, the improvement seems to be at idle.

    Any ideas for improvement would be welcomed!

    Was that 24 hours on 8.1, or pre-AU 10?

    It takes a few days for battery life to return to normal after a big update.

    Dan Tyndall,
    Battery life of 24+ hours was on 8.1 ... i've been on .67 and .189 for a couple weeks now - and just not getting any better. The only good side is the W10M just looks great, smooth - but, it did break a couple apps and really, my only BIG issue is battery life.

    I also recently purchased a certified refurbished Icon and updated to build 14393. Coming from a 928 running an earlier build the Icon's battery life is a vast improvement. I would say I could run light and get a fair amount of juice, 120 miles of GPS while running Pandora, a couple of calls, I still had some life left however I don't recall the percentage.
