    Exactly ! But the fact that I love my 920 sooooo much has prevented me from jumping on to the 1520 wagon and am waiting for the next lumia !

    my lumia 520 only last around 10 hours after the black update, but i believe the culprit is the outlook push sync, so i set to sync only once a day, and my battery is back to normal, around 25hours/ charge

    my battery is also very "strange". So ca. 20 minutes ago I was in the settings page and it showed me 41%, then suddenly it dropped to 39% (without showing me 40%). Then I immediately after I shuttet down the phone (normally by press and hold the power button) and switched it back on and I only had 28%(!!!!) left. I have no Google Accounts, 4 Mail accounts with sync every hour, every background task is enabled (I don't have very much (fb, whatsapp, metrotube, here drive+, 6tag, wheater flow, bing health app). And now I have 23%... This all happened in about 20 mins. It's very strange with a 2000mAh battery... But I think there is a battery calibration bug idk... hopefully it get fixed sometime... BTW is your micro usb port a bit loose, does your charging cable has a play or it fits and is fix?

    You say "strange considering a 2000mAh battery". For the size of the phone and thickness, it one of the smallest battery capacities around.

    Post after post after post I read the same thing, which is why I returned my Lumia 1020. As I said before on numerous occasions, I researched all these battery saver tips and apply it to my lowly Lumia 520, (sigh, really miss that 41MP camera). But the only way to get decent battery life out of the 1020 is to delete this and this, turn off that, disable this, delete apps and email accounts etc. Not much point in having this sort of phone then disabling, deleting and uninstalling all manner of items. A lucky few people do have better than average batteries in their 1020, but most have less than acceptable.

    I don't mind manually syncing my email on my 520 and other battery saving techniques. I do however mind having to do that on a flagship phone, plus get a glance screen with the added bonus of double tap to wake up, and then be told to turn all that off to try and get acceptable battery use.

    Which is why I opted to stick to my 520 and wait for the 1020 successor. A shame though cause the rest of that phone was awesome.

    It's not the size and thickness of the phone that's causing the battery drain. It's the resolution. The 625 and 720 has the same batteries but they can last two days of heavy usage (especially the 625).

    Anyway, do remember that the 1020 has an AMOLED screen, so pages with mostly white background will drain your battery faster. But your battery will consume less with black backgrounds. So web browsing could really be frustrating. Its AMOLED screen is one of the reasons why I chose the 1520 over it since I know that I'll be browsing the web for long periods of time.

    Anyway, GSMArena gives the 1020 a slightly decent score for battery endurance (61h), although it lasted 5 hours and a few minutes only on the web-browsing test.

    I've had instances since the update where my 1020 was fully charged and in sleep mode only to find upon waking it up a few hours later it was down to less than 20%. I've since concluded that it is due to a background process or processes (such as checking/syncing e-mail) being stuck, causing the CPU to be active full time. When this occurs I simply do a soft reset (power down and then power back up) and everything is good again upon charging. I wonder if this is effecting other Nokia Windows Phones handsets outside of the 1020?

    Do you think that the new OS Version of the Developer Preview could affect the battery life negativly? With the Dev Preview you will be able to get V. 8.0.10521.155 but originally the OS Version of the Lumia Black Package is something below (8.0.10512.142 or 8.0.10517.150, i don't remember exactly)...
