    Ever since my phone received it's OTA update my battery life has been outstanding. Anyone else experience better battery life?

    I want to see if GDR2 or Amber is causing the better battery, as have an 8X.

    Seems about the same to me, but the battery on my 928 is awesome.

    Yes indeed! With continuous usage the discharge speed never exceeded 10%/hour!

    Previously it reached to about 18%/hour!

    I got the update in my Lumia 920 and really, there is no difference at all. I guess the phone has a large bright screen that no matter what it well eat up lots of power.

    I am definitely seeing increased battery life, even with peek and tap to unlock on. Something was tweaked imo.

    I too feel the battery has been better since updating.

    Only difference I've noticed is that sometimes outta nowhere I'll drop up to 40% instantly. I had 62% earlier and my phone locked up, a soft reset later and I was at 26%. Not the first time that has happened either since the update.

    To those experiencing battery problems: is it possible that this increased rate of discharge is because the battery needs recalibration (like it happens on laptops)? I saw a post somewhere where the guy fixed his short battery life after Amber by merely resetting the phone. So try that too.

    Nothing noticeable here, but my phone usage goes in spurts throughout the day. Typically lasts me all day with little issue anyway.

    I will also add that my battery life has remained the same or has actually increased since completing the Amber update; I also have my glance screen on all the time. #kickingitretro

    Yes, my 928 also has better battery life. I thought it was just my "illusion" lol

    Going though the files from the factory release and the GDR2 stuff, everything was changed (or for that matter recompiled). New modem, new touch driver, new screen settings, ect.

    I also have better battery life. One day with normal usage from full charged in the morning and I usually come home with about 30-40%.
    However, my 920's battery improvement was apparently due to dispearance of "process stuck" problem but the better charge rate (it is still 20-30% per hour when heavy usage, the one with 10%/hour maximum is so desirable :)

    Sorry but people are describing a classic placebo effect. If something like that was on the table it would be in the change log. I would say battery life is about the same although reporting might be a bit more accurate. Initially battery life after the update was appallingly bad but a soft reset addressed that problem. Now it is back to where it has always been which is actually quite good.

    It IS in the change log.

    I found it over at AAWP, and they clearly state there that there is supposed to be a 10% increase in battery life in real-world usage.

    Also inside that fancy ffu/cab update, hidden away inside the registry, there is stuff for Bluetooth that enables low power profile mode/ something of that nature (I don't quite recall what they had exactly called it), also the new cellular modem and the new display/touch driver helps too.

    I've seen a few more hours on a single charge. On this day I had been using the phone for a good chunk of the day/night. Most of my use was between 7:30am-6pm. I watched a few videos, streamed music for many many hours, browsed the interwebs, snooped around on the wpcentral app, and played a couple games of uno and friends.

    Does anyone know if the GDR2 update fixed the problem of processes being stuck in the background causing battery drain on the L920? Mine is constantly at 7 percent when idle.

    7% per hour means your phone must have problems. I myself also have processes stucked righr after using the phone heavily. But post- Amber, the phone quickly get cooler after being used. When idle during night, the discharge rate is about 0.5%/hour, and during day it is about 2-3%/hour when not being used.
