I never leave batteries inside of my camera. When I finish taking photos, I always removed them and recharge them for the next time. As a Sony user my experience with the Sony NP-FW50 not only have a short life using the battery, but require long re-charges.
I also have several Canon bodies and cameras, and my user experience has revealed that they are long lasting

WOW, guess you never need to grab your camera to get an opportunistic shot.
My batteries have always been in ALL my cameras all the time unless they are being stored since the early 70's.
NEVER had any problem in all those years with the battery.

I have four Sony cameras and with default settings they all draw down batteries about 7% to 10% per night while turned off with my a6500 being the worst of the lot. There are settings you can make to slow the drain down while in-camera - "Google" the problem. However, with both Sony and a couple of other brands of aftermarket batteries I also experience out-of-camera battery drain - not as much with my Canon stuff. I use rechargeable batteries a lot and don't think I've ever had any that didn't experience drain to varying degrees even when not engaged in some kind of appliance, just some worse than others. I spent all day Tuesday swapping out rechargeable batteries from all my gear and accessories. I intensely disliked those $15.00+ camera batteries of yore that were good for 200 - 300 shots but it's dang near worth it to not be tethered to a bunch of different chargers all day, so many that you have to label them, and the batteries.

I would just take the batteries out of the camera. There is no point in draining them. They probably should be stored at 40% to 60% charge, anyway. Charge just before use.

Many cameras have an Airplane mode setting in the menu. Those that do also have a WiFi, Bluetooth capability. Turn Airplain mode ON to disable the wifi transceiver. Cameras are getting evermore smarter so more stuff is getting crammed onto the circuit board. Li-ion batteries have an internal drain rate. See Wikipedia for latest info dared to be published.

Don't you guys READ? He answered that in a 2nd post here.

I wish that you read all replies not just the initial one.

tdekany Loc: Oregon

You should read all the replies before posting. That way you 2 would not sound so clueless.

Do you have the same issues with all 3 batteries? How old are they? On a personal note, I used to have 2 wasabi batteries for my Olympus cameras besides the oem ones and both had the same issue after a while you are having but because the Olympus batteries were holding charge just fine, I knew it was the batteries so I got rid of them and now only purchase Olympus ones.

I use 2 cameras and have 4 batteries altogether. All Olympus ones. Recently, one of them started to lose the charge so I no longer use it. Unfortunately I can’t tell if this one is the original one that came with my EM1 4 years ago or not.

You should purchase a new Sony oem battery and see how that works. That would tell you what is going on. Good luck.

Yes steve2014 said what kinds of batteries he is using one is a Sony and the other two are Wasabi’s!

Paul Brannon Loc: Coolidge, Arizona

I was once told, by an incompetent source, that even if the camera is turned off, the lens still takes readings, and therein drains the battery, and keeping the lens cover on eliminates the battery drain. Any tech experts qualify or eliminate this "notion"?

But I will just go on, keeping the lens cap on, to protect my lenses.

Happy Thanksgiving everyone!

Why don't you just tell us which model or models you are aware of with this issue, and what the solutions is. The could help too.

How old are the batteries and approximately how many times have they been recharged?

It's is possible they batteries are worn out and need replacement.
No rechargable battery lasts forever, and some chargers are better than others.

If you'd care to post the part numbers on the battries, then we could look up the
chemistry and expected number of recharge-cycles.

Theere are many different lithium battery chemistries--although on a couple
are in use as rechargable consumer batteries. It's unlikely, but possible that
the batteries are two different chemistries Mixing battery types is never
a good idea. Mixing brands is OK as long as you are certaint hey are the
same chemistry.

It is very common for the same size battery to be offered in different materials:
for example, in button cells, LR44 is an alkaline cell (1.5V nominal) but SR44
--while the same case--is a silver-oxide cell (1.55V nominal).

Check the menu to see if the finder/monitor is on auto. The monitor should be selected when not in use. The eyepiece detector will use up battery life.

Storage was a lot simpler in mechanical film cameras (that only used the battery
for the meter):

1. Rewind and remove the film.
2. Make sure the meter is turned off or remove the battery.
3. Let the self timer run down, if it's set
4. Release the shutter.

Even after the advent of electro-mechanical and then microrprocessor controlled film
cameras, there was still a way to turn off the drain on the main battery. (If the camera
had time and date stamp, it was usually run by a separate watch battery in the door.)

The Nikon EM--even though an AP automatic camera--was designed so you could still
take photos if the battery was dead. The shutter defaults to 1/1000 when the battery is dead.
In those days, Nikon wasn't going to leave you with no way to take a photo. And this was
when batteries lasted for several months (at least).

How many days of shooting before your digital camea needs a recharge?

This is the process of diminishing expectations: whereby consumers are gradually
weaned away from the benefits to which they are accustomed. That's how everything
in your house gradually was replaced by something made of plastic.

Bet you think bookcases are made of wood? Not anymore! They are made of
paper-covered chipboard made of wood chips and plastic resin (usually amino-formaldehyde).
Chances are your subfloor is made out of it too.

Bet you think water-proofing products aren't water-based formulas? Not anymore!

Bet you think fire extinguishers are made of metal, not flammable plastic? Not anymore!

Manufactures will keep replacing materials and functionality with inferior substitutes as
long as consumers keep buying the crap.

Users of electronics products deserve a real off switch, that disconnects the power.
But switches cost a dollar or two, so you don't get one, sorry!

Reducing parts count is priority #1 in electronics manufacturing today. Battery life
(especially during storage) is a low priority.

If the battery leaks and ruins your camera, you buy another camera. Some warranties
exclude damage caused by batteries. Even when it is covered, the battery only has
to not leak during the warranty period--then the manufactuer is home free.

Consumers will keep buying the same bad product over and over, as long as the
marketing says it is "New and improved!". And when the entire industry switches
to no off switch (or plastic, or particle board) the consumer has no choice.

In ten years, probalby all cameras sold will have plastic lenses. And this will be peddled
to consumers as an upgrade: new technology! Glass lenses are "old technology" -- invented
in China about 1000 years ago. Don't be the last one on your block to swtich to new
polycarbonate camera lenses! Don't gt left behind :go glassless now!

Consumers are sooooo easy to manipulate---they'll even buy a electronics product that
doesn't have a real off switch!
