iPhone 5S battery discharging rapidly

Discussion in 'iPhone' started by David Fritzinger, Jan 11, 2015.

  1. I have an iPhone 5S, purchased right when they were introduced in
    September of 2013 (16 GB, iOS 8.1.2, on Verizin). While I had always
    thought it was using battery power a little faster than expected (and I
    have an incident ticket for this with Apple-they said the battery was
    fine), for the last few days, it has been going through battery power
    very rapidly. This morning, though the phone wasn't reallly used that
    much, the battery power went from 98% to 68% in about 3 hours.* Of
    course, I don't have AppleCare, so Apple is unlikely to do anything. I
    try to keep as many apps closed as possible, and am very careful to
    close any apps that use the GPS. I also keep the screen pretty dim. Is
    there anything else I can do?

    Thank you in advance.

    *By light usage, I mean that I spent about an hour listening to music
    through Bluetooth headphones, checked my email a couple of times and
    made a couple of very short phone calls.

    None of these are likely to make much of a difference.

    What I find is useful is simply rebooting it every now an then. Sometimes
    putting it into Airplane mode for 5 or 10 minutes helps, but more often
    a reboot will get it out of this "rapid discharge" mode.
    Bluetooth audio might do it. Weak cell phone signal. Sometimes you can
    tell if you check Settings => General => Usage => Battery Usage and see
    what's been eating it up.

    This has also worked for me. Hold down both the home and lock buttons
    until you see the apple emblem. (Maybe 30 seconds.) Then let the
    phone reboot itself.

  4. I know, but that is what Apple recommends.
    Actually, I did that earlier today, and it seems to have helped (well,
    over 8 hours anyway). Over the course of the day, the battery only
    dropped by about 5%. I used my phone to check stocks and email several
    times during the day, so the usage wasn't that much. Still, that was
    better than I had seen recently.
    I don't think it was Bluetooth, since using my phone at the gym with BT
    headphones is something I do pretty regularly. Likewise, cell service
    is pretty good most of the places I go. Checking battery usage shows
    nothing unusual.

    Anyway, after a restart, battery usage does seem to be down. Hope it
    stays that way.

    Thanks to all who made suggestions.

  5. As I said in my other reply, I've done that. It is something I do at
    least a couple of times a month, and this time I saw nothing unusual.
    However, rebooting the phone (just turning it off in the usual
    manner-holding the power button until it turns off and restarting it
    via the power button until I see the Apple emblem) seems like it may
    have worked.

    Again, thanks for your help.

    Most likely what happened with the reboot is all the background apps
    that were running got stopped. Sometimes I bring up the Task Manager
    (?) with a double Home button and swipe away the apps I opened once and
    seldom use but are still resident.

    that list is a recently used list, not a currently running (or
    resident) list.

    most of what is in that list has been evicted by the system
    automatically.
