    Hi everyone,
    I updated my Lumia 925 with the black update in January. Before update whenever the battery is fully charged (100%), the estimated remaining time used to show something like 1 day and 15 hours. But after the update even it shows charged 100% the estimated remaining time is shown as 23 hours. Is there any problem with my device or is it common.

    Kindly do reply. Thanking you all in advance for your time and replies.

    Hi

    this is common on Lumias 920, 925 and 1020.

    Battery meter is very unreliable on these phones.

    Thank you Spriteman. I thought there is some kind of problem with my device. If, as you said battery meter reliability is true, then that certainly follows the windows tradition of "showing 30 mins to copy a 20 gb file where as the copying might finish within 15 mins or may be more than 30 mins.

    Hi

    You can try this :
    Use your phone until battery is 10 %
    reboot your phone (power off and on)
    Battery sometimes jump from 10 % to 50 % (and more)

    It does that everyday on my 920.

    It's merely an estimation. Why bother that much?

    its trying to predict how long it'll last with normal usage I believe
    my 920 would last a lot longer than the 15 hours estimate if I left it alone

    And battery estimate is based on your usage pattern. Suppose, you were draining your battery(by using the phone heavily) within 10 hours of charge, then the estimate battery remaining will plot down, will start showing you 10-12hours. Instead of whats the actual battery capacity(strength)!!! So please dont consider the estimate as the final yardstick. It's totally unreliable. You can install battery apps to see if there's any significant battery % per hour which points toward a rogue app or you're using some background data app. This's better than looking at the estimate battery time. Battery app can also warn you if there's something sucking your battery without your knowledge.
