    My Discharge-Rate is also between 4-5%, so I think it's normal. Where are the People with a <1% Discharge-Rate?
    I have 3 backgrounds apps (bing news, weather flow and battery) , emails synched on arrival, location wifi and bluetooth on, glance on peek, screen sensitivity to low and no double tap to wake: I am under 1%/h on idle, and my 1020 lasts me around 30 hours with normal usage (calls, texts, web, handfull of pics and light casual gaming_Skulls of the Shogun and Robotek_).

    I had battery drain problems on my first day, but then realised the network setting of the 1020 was set to 4g by default: my phone was constantly moving between frequencies (I don't have a 4g plan). After setting maximum data speed to 3g I got great battery life.

    I just did factory reset and didnt put in any emails or anything. Now the phone idles at 9% currently, after 30 min rest. I'm getting really tired with this phone.
    The 1020's battery is supposed to be very good, according to Nokia, reviews and many users on the forums. I'm going to get it replaced, because I really love this phone, and I want to give it a second chance. At this point, I think it's clear that anything we're able to do to the phone software-wise will not fix the battery problem.

    At first, I thought I got a knock-off device because of the terrible battery, combined with the fact that I did buy this phone in China. Seeing someone else with the same problem has thankfully gotten that possibility out of the way.

    Yeah I did. Gonna try to have it replaced. What are your settings? Are you using wifi/3g?
    At 1.17% that's with all connections off. I have 3% idle now on wifi. If constantly connected through LTE I probably won't be able to make it last my entire 8 hour work shift, even on idle.

    I returned it today and cancelled my contract because I wasn't allowed to exchange it to a new one.

    I really liked WP8 and the phone itself, maybe I'll buy another one later

    I think 1% Discharge-Rate is only possible with slow Internet (<4G). I always have 4G on and I'm happy when my Phone lasts 8-9 Hours with normal usage.

    1% discharge rate might only be possible with no (or little) active connections, but it seems 4%-5% is possible with active connections and should get you through a day.

    I have LTE active all day and WiFi as well when I'm at home (which is all day half of the week), with three email accounts (one push and two hourly) and about six active background tasks (weather, news, battery etc). With normal use I get less than 5% discharge rate and can easily make it through a day (6:30 AM - Midnight).

    True 4g is only starting in France, and I do see users commenting on how power hungry the connection is.
    I'm on Hspa+ (wich I cetainly wouldn't call "slow internet"), and it doesn't seem to hit the battery too hard. Granted, 1% discharge rate is only when the phone is in sleep, and I do have few background apps and only 1 push email adress.

    Judging from the comments here and on other battery threads, am I correct to assume that 4G is only problematic in markets where it's still in the process of being deployed? I read other comments from people who dont seem to have any battery issues while on 4G but in my case it eats up my battery and heats up my phone real bad when used for prolonged periods (upwards of 45 minutes). 4G is still in its infancy here in the Philippines and my 4G signal is often unreliable/intermittent.

    I think the Problem with 4G in Countries like Germany, France and the Philippines is, that the 4G-Signal is not so strong, so the Lumia 1020 has always to search for a good 4G-Signal, that costs Battery!

    That seems to be an accurate assessment especially since I also observed heating and fast discharge when I have both WiFi and cellular data on at the same time...

    Checked around on the forums and found http://forums.windowscentral.com/nok...-opinions.html

    74 pages long about battery drain.. 920 seems to suffer from heavy battery drain aswell.. I found the same for 925.

    Just a follow up..

    I returned the first 1020 and actually won a brand new 1020. Out of the box, the battery seems much stronger with this new device. The first one died within hours on the first charge. The new one lasted around 24 hours with pretty medium/heavy use on the first charge and it should get better by every charge.

    Some other stuff i've noticed is build quality. The first one would creak in the plastic if i gripped it to hard. If i did some pressure on the side part where volume button is the plastic would move alittle and make a creaking sound. This new one is MUCH more solid, no sound whatsoever.

    Anyway, I hope this new device servs me well.

    EDIT: Forgot to add, i also updated to GDR3 on this new device. Maybe that fixed some problems aswell.

    I am seeing a discharge rate of 5-6% with Whatsapp, Facebook Beta, Outlook set to update 'as items arrive', Gmail set to sync every two hours and Lockmix running in the background at idle. My firmware version 3050. Is 3350 the next update?

    Sorry, my fault ;). 3050 is correct.

    Is it possible that it's only a selected batch of 1020s are facing this battery issue? And the ones that have a very low discharge rate are actually from another batch?

    My new one has alot better battery life, but when i'm using it - it drains quite quickly. I used whatsapp for about 10 min and it dropped 10%
