    I'm finally at 100% after being plugged in most of the days except for lunch and breaks. We'll see how it is tomorrow when wake up. Could be a fluke with may one of my new apps.

    I noticed significant battery drainage on my Lumia 1520. I am currently looking at my screen with 90% battery life remaining. Estimated time remaining: 11 hours. I have Battery saver off at all time. I turned off wifi. I have Bluetooth on. I am a heavy user. I constantly play games (Throne wars and Cloud Raiders). I wake up at 7.30 with phone charged overnight (12-7.30) and I have to charge it in the office since I will be using it heavily throughout the day. Is there anything I do wrong? Why all people here could charge their phone once every two days? I am with WP 8.1, AT&T, microSD sandisk class 10. Could it be the microSD causing this? Please help.

    Everyone uses their device differently, my 920 could be pushed to a day and a half with light usage, 1/2-3/4th day with heavy usage, typically a day with normal usage.
    microSD should not factor into the battery usage at all. Its probably you gaming a lot more than some people here.

    My 1520s dropping 20% in idle overnight. WHAT GIVES?

    Pulling my hair out here.

    Cortana unpinned

    Battery saver Off

    Even took Cortana out by setting region back to my native region Australia.

    Did a complete drain and full charge last night.



    And then there are some people here that average 3 days without charging. what the?!

    20% drain in what, about 8-10 hours? That is only about 2-3% per hour. That's actually pretty good. Plus, why not charge it overnight

    Thanks for the response

    I dont keep it charged over night cause i read keeping batteries charged overnight reduces battery life.

    Yes correct. 20% over 8hours.
    Straight after I got the 2nd update for 8.1. The battery life increased dramatically. I would only lose 5% overnight.
    It's gone down hill since that period.

    Well, if you keep it off the charger at night, and are concerned about battery life, you could set it to battery saver mode while you sleep, or completely shut it off. That's crazy that you had only 5% drain. You could also look at which apps are allowed to ruin in the background, and maybe disable the ones that use the most battery.

    I've forbidden all apps bar 1 from running in the back ground.

    That app is a day counter. Counts downs days to an event.

    2-3% drain per hour on a 1520 is not good. I get a constant loss of 0.3% per hour over night and that is with

    Location on,
    WiFi on,
    Bluetooth on,
    Glance set to peak,
    27 apps allowed in background,
    10 or more live tiles.
    Everything is being backed up

    I have turned of WiFi sense and battery sense turned off.

    My battery has improved a bit over the last week or so. I was getting between 10 and 13 hours of screen on time over 3-4 days but that seems to have increased by around 15%

    I was getting standby battery loss of about 0.2-0.3% per hour on 3g but I'm now getting 0.3% loss per hour on 4g but that could be down to a better signal with EE

    Yup that's what I meant to say. I am using the charger that came with the phone (at least when I am at work). Hoping the other fixes recommended above will improve my battery life/lessen charging time.
    So you are using the wall charger or just the wire of the wall charger plugged into something else?

    I am using the black Nokia wall charger adapter with the while mini USB cord that came with the 1520. After making changes yesterday, it looks like the charging time has improved. Must have been a fluke.

    Damn son, what's going on here. I'm tempted to rolling back to 8.0. Is that even possible? I factory resetted and it went back to 8.1. I think I'm screwed.







    Whens 8.1 real release due.

    Hi all, sorry to arrive so late to the discussion. The first 8.1 dev release was fine, I noticed zero difference in battery performance. Since update 2, I just cant get anywhere near the same out of it. My usage is minimal through the day, an odd call, and a couple of texts, perhaps a little email viewing. My phone is charged overnight on a Nokia wireless charger. A couple of days ago I had to recharge the phone while at work. Not done that since I used the wireless charger. Had to charge today after being home for an hour. Barely used the phone today. Using a 920. Wireless network on, Bluetooth off, WiFi on, most background tasks off. Very few live tiles either. One thing I have noticed though is that the location icon comes up quite frequently. I never have gps on by choice. Since 8.1 my phone gets very warm very quickly. Noticeably warmer at all times of even very basic use. No intense graphics games.

    I'm having the same problem with my Lumia 820, some time ago charged in two or three hours max, but now from 0% at night it have 60% or 70% re charged in the morning, I think it is a problem with the 8.1 developer preview

    Yes you can go back to 8.0 any time you want using Nokia Software Updater for Retail. Bing it.

    Not sure how but I have always got great battery in all my phones. I know that it is supposed to be bad and all but I still let the phone go dead(usually around the first of the month so I can keep track of it) I never leave the phone on charge after it is fully charged, I let the phone go down to around 10% before I charge it.

    With 8.1 I did a hard reset before and after I installed it and only updated all the system apps both times and then I set the phone up as new so I did not restore from a backup. All my phones batteries have improved but the mops improvement is on the 1020 which has about 30% better battery now than before when on 8.0

    With one of my 925s I did a test and reverted back to 8.0 and restored all my apps and settings that I had backed up before I got 8.1 and I installed 8.1 again with out the hard resets and I had a load of problems so I then hard reset it and restored form a backup and that got rid of some of the problems but not all so I again reverted back to 8.0 and then installed 8.1 again but the way I did it with all the other phones(see list below) and again the phone has zero problems.

    Obviously the first couple of days after installing 8.1 the battery was bad but then it improved and in the case of the 925s the battery is about 15-20% better than when on 8.0

    As for my 1520 I chargers it this evening and it was at 8% and 5 days and 6 hours from last charge.
