If the battery is low there is no wake -up app that will work.

If you want a battery low alarm then it is already there.
You do not need an app.

Wait until your galaxy 3 shows the low battery warning.
On the phone's homepage at the top, pull down the notification bar, then tap on the red low battery notification.
You will see a power saving option page that has the battery options.

I am looking for alarm that will wake me from sleep (even if phone is powered off but has battery power). Michael-Best is suggesting a notification that tells me battery is low.

>> even if phone is powered off but has battery power
What you're asking is not possible. Phone off means it will do nothing anymore, no app out there will be able to wake you once the phone is off.

Only further suggestion we can make here is that you connect a charger to see whether the phone does not power off (so it will wake you).

If the phone still powers off then it may be defective. You can also buy a new (Samsung) battery for the device and see if that helps. Original batteries for SIII are still available and not that expensive (around $20).

@NVIT - Samsung SIII is too old for Samsung to deliver updates. There are probably no updates available anymore.

It is possible to wake a phone that is off,  at least my experience had shown with juice defender it would drain my battery even though my phone was off.  The events recorded in JD indicated it was turning the phone on every 30 seconds to check battery life and in turn draining the battery. That was several years and phones ago.

But that battery saving app completely depleted my battery every night.

On the SIII I had, I just disabled WiFi when on battery for the night. No issue at all.

first to suggest jd which may work. requires me testing
Gerwin Jansen, EE MVETopic Advisor Commented:
may work? Not sure then? I don't think that answers your question but if you can post your feedback after testing. Thanks.
