    I'm using L1520.
    Since it was still on 8.1 GDR2, there is a little phenomenon happened:
    - When the battery at 50% it showed that "Battery Critically Low" sign and then turned off right away.

    - I tried to turn on and noticed the battery now at <10% (usually it show 2%), the same Low battery sign showed up right after the windows logo and phone turned off.

    - After like 3 attempts, if I locked the phone right away after the logo, it would "survive" and then lasted probably for another 3-4 HOURS (the longest it's reached was 6 hours!) if I don't toy with IE or social networks, just call and text.

    Now I'm on W10P 15036, and that "thing" still goes on and now it start to show the "Battery Critically Low" symptoms when battery in the 70s%.

    It's so frustrating! The L1520 is supposed to be a battery monster for crying out loud, now it barely last 2 hours then that thing happens.
    Is my battery dying? Is it a bug? Anybody had the same issue?

    That's really weird issue, not having such problems on both of my devices, L925 & L930 as a matter of fact I have never heard of such issue...
    Have you tried to hard reset your phone? Just to be sure it is not software related problem?

    I might just have to resort to that as the last solution. It's just i've been too busy to journey through that route as I have so much date to backup and restore.

    Also I look up for a battery replacement by a MS-certified center, it costs $60 for replacing and shipping.
