NX300 Battery Drain when off?

My nx300 appears to be draining the battery when stored in the OFF position with the kit 20-50 lens mounted.  Happens both with the Samsung OEM battery and new Wasabi's I just bought and charged.  Appears to be about a week or so and the battery in the camera is completely dead, while a spare I charged at about the same time still has almost full life.

Anyone else experiencing a similar situation?

I have the NX300 and the battery drain you describe is certainly not normal. Sorry to read about the issue.

Thanks, and that's exactly what I'll do now..  I do seem to get good life out of the Wasabi's during a day of shooting, so now with 3 batteries, I'll just follow your suggestion.   When not in use, no power....

The big question is: Is there a camera-internal Mini-battery to support the clock and perhaps settings ?

If there is a camera-internal Mini-battery, then it is not great to take the battery out for a long time, because then the camera-internal Mini-battery gets flattened, and this is not good for the camera-internal Mini-battery.

If there is no camera-internal Mini-battery, then you can indeed simply take out the 1130 battery.

I have a tendency to think there is no camera-internal Mini-battery in the Nx300, instead a capacitor, which would not be hurt.

But I like to know it for sure.

On my old Panasonic cameras, there was the camera-internal Mini-battery problem-

So far the OEM's I do have are all really good in keeping the capacity even when sitting in the camera and the switch set to ON so that the camera is in Stand-by mode

for non OEM Batteries I would not do the same as I have at least three that have a high self unloading tendency. Did you observe thatthe 3rd party battery unloads itself after a while when outside of the NX ?

If the observed behaviour (unloading within the NX) is the same for OEM and 3rd I would assume that there is a power drain within the NX as I have not seen that with any NX I have had so far.

I know that this is an old thread but I have just been called by Samsung Customer care about battery drain when the battery is left in the camera without using it.  I contacted them because if I leave the camera for about 3 weeks, the battery will be drained within 5 photos.

He told me that it is quite normal for the batteries to self discharge in the camera  in 2 weeks if not used.  When I asked him if there is something working inside the camera to discharge the battery he said that it was beyond his technical ability to answer that.  I also asked if it would be better to remove the battery from the camera when not being used, he said "I could give it a try".

This is a very unsatisfactory state of affairs, "2 weeks" to discharge the battery in the camera? I use original and after market batteries and they all do this.  And as for the "technical competence" of the Support staff words fail me.

Why not just remove the battery when you're storing it then, if it bothers you? Mine drains too, but I'll either pop in a freshly charged battery (I have 3 after all) or plug in the micro usb charger (I have many plugged in for cellphones, etc.). No biggie.

There are metal contacts that are conductive that the batteries are constantly pressed up against. It drains batteries. For example, that's why electronics and remotes that are shipped with batteries in them have a tab pull somtimes to remove the barrier which prevents battery drain and operation.

I have 3 Fuji cameras and none of them discharge their batteries for months. Is their something special about Samsung's as they all have metal prongs that the battery connects to?  I agree I can take the battery out but will it lose settings like time and date etc. Why does this apply to Samsung cameras and not others ( unless you know different).

I would not say "Samsung" but NX300...

I did have one NX300 where the main board got changed and only after that exchange, the camera did show the battery drain when even originial batteries where left in the NX300.

With NX Mini, NX20, NX30 or Galaxy NX I do not have this at all.....just that one NX300 POST exchange of the board... prior to that repair (defective USB) nada, the second NX300 I did own nada... both did not show that, so it might well be some charge of motherboards only.

Hrm, I've not noticed any unusual discharge with my NX300M. Maybe it has newer components, but I was under the impression that NX300 and NX300M are basically the same in terms of software and hardware, minus the difference in screen tilting/additional feature for selfie mode.

I have two original Samsung 1130 batteries. They do not self discharge in weeks, in the Nx300 or outside. But Samsung may make no promises so Samsung does not have to replace anything.

even after upgraded to the latest firmware 1.4, feel slightly better but still battery drain

I know this is an old thread but you miss something about battery life. Letting a battery go flat (0 volt) shortens its life. If a battery goes flat too often it will die quickly. Li-Ion battery voltage should not go below about 2.5 volts per cell to preserve its lifespan. As you cannot change the small internal battery yourself most of the time, it is safer to avoid it to go flat by letting the big battery in the camera when the camera is off. The big battery will keep the internal clock running and the personal configuration data much longer than the small internal battery alone. But you must think about replacing the big battery with a fresh one before its voltage go below 2.5 volts per cell...

The internal battery on my Samsung NX300 won't hold a charge and thus the date / time is continually wrong. Is it a bad battery, or maybe a bad capacitor? Thanks, MikeSor

Only a few days ago I tried my own NX300, after leaving it in a drawer for several months - and yes, the battery was flat and the date/time needed resetting... and those were then lost afresh when I removed and reinserted a charged battery.

Good news for me though was that it did settle (after leaving it with a charged battery in it for a day or so), and now works as it had done previously... although I've not left it without a battery in it for more than a few minutes.

Some time back I had a very similar experience with the NX3000 - which needed a little longer, but did eventually respond in the same way! [That one has the benefit of USB charging, so is easier to "top up" occasionally, which I now try to remember to do!]

So I'd recommend persevering, as the capacitor - or whatever it is inside - does seem capable of being revived.

Good luck,
