I have noticed during the last year that most all batteries for everything are being made in China and the very poor qualities are being used,

Some batteries run down in a few months of just sitting there doing nothing,

Hello,

Somehow I have this issue with battery drain for a used Nikon D7500.

I try to get some feedback about the Nikon d7500 battery usage from someone who use such a body. Can I present my situation and maybe you can give me an answer if possible about what it's your battery life combined/in conjunction with your shooting style?

I got an used Nikon D7500 with only 1300 shoots .
I have some issues in trying to check if the battery/body have some problems (It seems that somehow the battery power is not conserved like it should).

- Battery status in the body software looks fine: marked as 0 (New).
- During the body power off period there is no power draining.
- First I receive the battery empty, I fully charge it and: play in the menus to check the configuration, do ~5 shoots in live view, 1 min o full HD video, review some images, do some touch screen tests, etc (cumulated ~1h of usage). After that I gone out to start shooting. At 25% battery remaining I had 240 shoots (no flash, no live view, no snap bridge, only viewfinder with picture review ON). It seemed to me not so good.
- Second test was to disable touchscreen, Airplane mode ON (no bluetooth or WIFI). The main display was used only 4 seconds after each picture was taken in only viewfinder mode. At 55% I had 380 pictures performed (finest NEF+ finest JPEG). Much better I said :). After that I have done another test as working on the display ~20 minutes- settings, pictures review. I got 6 % of the battery gone.


Thanks a lot for any further information!

Hello DavidRC:

I've done pretty much what you've done except for "disabling touchscreen", which I'll try next. I also removed the battery for about a week and then re-installed it. About 1% discharged. Is that an indication of bad battery?

Batteries, both Nikon and Watson, that I've had for my D80, have maintained full charge even after long idle times, but the D7500 is a much different camera with so much going on.

I'll get back to you after I do some shooting with the disabled touchscreen.

I'll get back to you after I disable the touchscreen.

Regards,

Hello,

Regarding the "About 1% discharged. Is that an indication of bad battery?". In my personal opinion I don't see it as much as a problem. Nikon in their manuals state that: "Use batteries immediately after charging. Batteries will lose their charge if left unused."
https://onlinemanual.nikonimglib.com/d7500/en/25_technical_notes_12.html -> Here you can find (if not already done this) some information about battery life.

"The following can reduce battery life:
Using the monitor
Keeping the shutter-release button pressed halfway
Repeated autofocus operations
Taking NEF (RAW) photographs
Slow shutter speeds
Using camera Wi-Fi (wireless LAN) and Bluetooth features
Using the camera with optional accessories connected
Using VR (vibration reduction) mode with VR lenses
Repeatedly zooming in and out with an AF-P lens."

What are your tests numbers? Number of shoots per you working style (only viewfinder, review picture or not, etc).

Thanks,

Hello DavidRC

With the Covid I haven't a lot of opportunities for using the camera; no vacations, not traveling into New York City, one of my favorite places for walking and picture taking, etc.

I normally use only the viewfinder, quick picture reviews, jpegs, not NEF, very little flash. My favorite lenses do not have VR.

Hi,

While doing a search on the 7500 battery problem, I found your forum and decided to join in. I just bought the D7500 and have noticed the problem with battery drainage. I check my battery percentage and it will be fine (about 80% full) but a few days later, it's down so low, I have to put in a new battery. I know it's not my batteries so somehow, they're being drained while sitting. I have a D7000 and have never had this problem. I guess it's something I need to get used to.

There were a number of settings in the replies to check and turn off. Have you reviewed and completed all those actions, if applicable?

If you have a new or spare battery, a simple test will reveal the fault. Change the batter to a freshly charged cell, If the problem does not recur, your old battery has come to the end of its useful life. Also, make sure the battery terminal is clean, and there is no sign of leakage, swelling or overheating. Make certn that the charger is operating properly.

If the batteries are in serviceable condition, a long duty cycle or using live view may drain it more quickly but that should not happen after 7 shots.

If the problem continues with a new battery, the camera requires service.

At first glance, it sounds like this might be a battery problem. When you put the freshly charged battery in the camera, does it show 100%? Does the shot counter on the battery status screen reset?

How long have you had the battery? Can you make an educated guess of how many times you have charged it?

If it were me, I'd use that battery down to 20% or so, then recharge it. Leave it on the charger for 4-8 hours after it indicates that the charge is complete, then put it in the camera and see if the behavior is any different. There is a chance that either the battery or the chip got out of whack when it discharged so completely. This might correct it. It is also possible that repeating the use and charge cycle two or three times might improve its performance.

Hello Gyroflyer:

I haven’t had the problem you’re seeing of a large battery drain while the camera is not in use. My initial concern which I posted on UHH was a result of comparing the battery life of my D80, with that of the D7500. Two very different cameras as far as battery usage.

You could simply check the drainage with the battery out of the camera and with it in the camera during camera off periods. Do this also with your spare. If both batteries drain alike while in the camera, it could be the camera causing a short. If they both drain alike while out of the camera, which I doubt, it would be the batteries.

Regards, good luck, it’s a great camera but very different from your D7000 as far as battery use.

Thank you Marcoj,

I just wanted to let DavidRC know that the problem is happening to me also. I have read and am trying some of the troubleshooting that you all have offered. Someone suggested to put it on airplane mode and I believe that might have been the solution so far. I will also check the batteries out of the camera as you mentioned.

So far I love the 7500 but need to get used to a couple of things that differ from the 7000.

Thanks again.
