Dochayden Posted January 4, 2019 Share #1 Posted January 4, 2019 Advertisement (gone after registration) I would like to ask if anyone had a same issue that I encountered with my Leica M10P. When I turn on the WAN to try to connect and transfer photos to my iPhone, the battery suddenly drains from 100% to 0%. I tried it on three batteries, 2 of which are brand new (literally just opened today and was bought last month). I believe the problem is with my Leica M10P. Any advice on what needs to be done?

pico Posted January 4, 2019 Share #2 Posted January 4, 2019 Did you fully charge the two new batteries before use? Link to post Share on other sites More sharing options...

I charged up to the point where “80%” was already blinking orange. All three of them. Then when I insert it into the camera and turn on WAN the camera suddenly turns off and won’t turn on anymore. So I’d replace the battery and it turns on again, but when I do the same the camera turns off again. I assume the battery is drained because when I put it back in the charger it takes an hour again to become full. Link to post Share on other sites More sharing options...
mmradman Posted January 4, 2019 Share #4 Posted January 4, 2019 As you say battery discharges rapidly, does the camera or battery become warmer than usual? Reason I ask is the way you described the problem activating WLAN has he same effect as short circuiting the battery which is frankly hard to believe. 1 Link to post Share on other sites More sharing options...
pico Posted January 4, 2019 Share #5 Posted January 4, 2019 (edited) After you charge the battery and before doing anything else, check its status - press the middle of the button/wheel on the rear (#30). Just click it once; do not click and hold down. Does the battery show adequate charge? The display below show only marginal battery remaining for WAN, or even Live View.

scott kirkpatrick Posted January 4, 2019 Share #6 Posted January 4, 2019 This sounds like a hardware problem. I've gotten the wifi to start up correctly on the M10-D with as little as 10% of capacity remaining, as estimated by the M10's indication. However, when I put that battery into my NiteCore charger, it seemed in actuality to be only about 50% discharged. Maybe battery indicators are not reliable -- an open circuit voltage (which is what is measured) may mean different things after different discharge patterns.

wlaidlaw Posted January 4, 2019 Share #7 Posted January 4, 2019 Advertisement (gone after registration) All Leica cameras seem to drain the battery quite quickly when being used for internet access, either via the app or via a webserver.

I assume the battery is drained because when I put it back in the charger it takes an hour again to become full. Charging to 80% is not charging fully. It is inadvisable to make a habit of charging to 80%. It will take quite a while for the battery to get to 100% from that point, as the charging current will drop as the battery gets more full. One hour does not sound unreasonable. Sometimes the camera-battery communication gets messed up. The battery needs to be fully charged and run down completely in the camera to recalibrate the system in that case. Run it down by disabling auto-shutoff and switching on the LCD, and leave it.

scott kirkpatrick Posted January 5, 2019 Share #10 Posted January 5, 2019 (edited) I agree with Jaapv's suggestion. With my M10, I found a fast way to run the battery down is to set auto shutdown OFF (so it won't shut down by timing out), turn live view on, and wait for about 2 hours. Then charge the battery up fully in the Leica charger, which has a careful protocol. Do it twice (since you don't seem to be starting with a fully charged battery) to establish a baseline. The M series of cameras is a bit too conservative in estimating battery depletion -- I've seen them show only 10% left when the battery recharge time and amp-hours required suggests that it was really only about half depleted. The L-mount cameras, especially the CL, go the other way. They have only a five-bar indicator and they tend to stop with little warning.

PhoebusXS Posted January 7, 2019 Share #11 Posted January 7, 2019 I guess either you go to a Leica store and borrow their battery, see what happens. Or, fully charge your own battery then try that again. Either way if there's still problems ask them to replace the relevant part. Link to post Share on other sites More sharing options...

It takes way longer than an hour to charge a battery to 100% from 0%. It sounds to me like you are part charging the battery and the WAN connection is trying to tell you that there isn't enough charge to complete further operations safely, in a similar fashion that you can't download new software to a phone without enough charge in the battery.. 1 Link to post Share on other sites More sharing options...
scott kirkpatrick Posted January 8, 2019 Share #13 Posted January 8, 2019 (edited) Set the M10 with automatic shutdown to OFF. Turn on liveview and just leave it. The battery is drained when the camera shuts off. Along the way you can review the state of the battery with the info button (middle of the 4-way buttons on the back). It should take two hours to completely charge up. Charging is complete when the green light and the orange light are both steady.
