    Hi, everyone. Now coming the iOS 11, so before the final version be released, I updated my 5S from iOS 10.3.1 to 10.3.3. Now the battery is worse than before, I have to charge it several times in case of sudden shutdown. Now it's always power off when the battery percentage show 30%. Is there anyone have the same problem with me?
    In this case, I am hesitating at iOS 11, and I wonder if there a chance for me to downgrade to iOS 10.3.1 without jailbreak? Or should I change my battery?

    The signing window for 10.3.1 is closed. You won't be able to downgrade.
