    I fully charged my iPhone 4s. Put in standby mode and set it on the night stand. Awakened 8 hours later to a 40% charge. I am visiting family and the room I am in has a weak WiFi signal and the cell signal is weak here too. Could that be the cause?

    The usage stats said 6 hours standby and 2 hours usage. What would have been active for 2 hours?

    iPhone 4s
    Not jailbroken

    My son's had the same thing happen last weekend. I bet it is some setting that keeps it 'awake' all night...

    You may want to restore the iPhone in iTunes, especially if you have recently updated the OS.

    It could be because of searching for signal try it fully charged in a spot with better signal.

    Check your usage. If its the same as standby then you know what the problem is. It happened to me few times and I always had to restore from backup which is inconvenient. Then my good friend advice me that its better to just let the battery die and that will fix it.

    I put my iPhone on charge last night and woke up with it at 100%

    Also, it may be a good idea to put your iPhone on airplane mode when you go to sleep.

    It's probably not that good for you to have any mobile phone near you (especially your head).
    Also, it can stop your iPhone from waking you up ;)

    Absolutely. Feel free to refer to countless prior threads on battery life and poor coverage (applies to just about any mobile device out there -- not just iPhones). Any reason you didn't charge it while you slept?

    How would we know what you have/use on your iPhone?

    because it was fully charged. No need to keep it on charger.
    It was in standby. Nothing should have been active.

    Anyway. Airplane mode last night and battery was at 100 this am still. Must've been signal searching.

    Fix the problem easy

    If you check the usage and standby and usage are the same you will have a problem with your battery life. Apple gave me two new phones when this problem happened to me. But in all things there is usally a way to overcome the problem. This works for me. Plug phone into power charger till 100%, turn phone off while plugged into power, unplug phone and turn back on you will see there is no time for either usage or standby. Plug phone back in for a minute or so and unplug and wait a couple of minutes and check usage v standby and they will be different as they should be. Good luck.

    Maybe someone in the house (a kid, or snooping relative) came into your room while you were asleep and messed around with your phone for a couple hours.

    Or, do you have any tracking apps installed on your phone (Find friends)? If someone was looking for you, it would activate your GPS, which could drain your battery a lot.

    There are many different aspects that could contribute to the massive loss of battery life overnight. Try restoring your phone and leaving it on overnight. If the battery loss is minimal, it's definitely your apps that are contributing to it.

    If not, your battery needs to be replaced.

    Looks like this was solved back in May, people...
