Sony A6000 Battery
Aug 4, 2015 07:55:37 #
Hello - I am a bit perplexed with the battery drainage in my Sony A6000. I must first admit that I have been using a pair of generic batteries (vivitar) for awhile. I have not observed (or paid attention) to the original battery for this behavior. The problem is that even when the camera is switched off (which it is most of the time), there is significant battery drain. For example, in 1 day the battery drains from 92 % to 78%. Is this normal A6000 behavior or cheap battery problem ? Any comments are appreciated.

I have the Sony A7II and the battery drains really fast on it also. Yes, just sitting there on off is a drain too. I ended up getting 2 more batteries for it. Just have to remember to keep them with me at all times. It is a bit of a disappointment they don't last longer.

I use Sony and watson batteries. I get that much drain with the camera off after about 3 weeks.

Ditto for me. I think the best solution is to remove the batteries if the camera is not going to be used for more than 4 or 5 days

I have an NEX-6, the precursor to the A6000.
For what it's worth, my Sony batteries last far longer than the generic batteries I have.

Yep.
You will have to buy enough batteries to have them available when needed.
That means changing your expectations on battery life when you deal with an EVF mirrorless camera.

CHOLLY, I have enjoyed your in-depth technical explanations on various topics in the past. Is there a reason for the drain on an EVF mirrorless camera while it is off?
And, to pick your brain further, is there a good reason NOT to choose a Sony MICL camera instead of a traditional DSLR as my next step up from a bridge camera?

OKsprat, while there IS some drain on the batteries during storage, the BIGGEST draw on power is during the power up stage when you turn the camera on.
EVFs are EXTREMELY energy intensive, as are the majority of the other steps in the power up process with Sony Mirrorless and Hybrid cameras. Everything from sensor cleaning to a full system check.
So while folk may think their battery was drawn down while sitting on the shelf, the big dip in voltage occurred during the power up and previous power down cycles.

Make sure that you have "airplane mode" turned off.

Airplane mode on uses less battery, as it disables all wifi functions.

Whoops - try again. Have a sony and a "power 2000 battery for my a6000. The sony lasts slightly longer.
All Li-Ion batteries drain just sitting in camera. Mine average about 2% per day.

Some months ago I published on UHH the plots of measured battery drain for the Sony and Promaster NP-FW50. The 100% to 6% drain for Sony averaged over 4 runs 19 days. The same drain range for the Promaster averaged over 3 runs 27 days.
Try turning Airplane mode off in wireless menu. Evidently the wi-fi transmitter remains powered when the camera is "off." Doesn't make sense but might there have been an unfinished feature by which the camera could picture file download when "off." This, if futurely possible, would enable downloading when general camera power requirements would be at a minimum.
The one experiment I have not tried is battery drain when "on."

According to Wikipedia article on Li-ion batteries the self-discharge rate is tenperature dependent: 8% per month at 21 C; 15% at 40 C; and 31% at 60 C. Because battery power derives from a charged battery being at a higher energy state than a discharged battery, there will be a thermodynamic driving force for a Li ion to move from the anode through the electrolyte to the cathode. The driving force will derive from change of anode/cathode energy state and diffusion through the electrolyte. I have been threatening myself to put that data into a activation energy and entropy calculation routine. But I am lazy.
