What is the expected discharge rate per day when powered off?
Iām not sure why that would be considered a safety function, since depleted batteries are the absolute worst thing you can do to a battery beyond physically damaging it. A happy battery is a battery between 20% and 80% of itās capacity, with the nominal charge being 50%. Anything outside of those parameters damages the batteries. Keeping the battery at 100% is almost, but not quite, as bad as keeping the battery at 0%.
With no control over the discharge, and no control over the charge, this is basically intentionally damaging the battery. I can charge it and let it discharge to say 70% and then turn it off, thereby keeping the battery in good health. But if itās discharging itself when powered off, there is nothing I can do to prevent that. I wouldnāt classify that as a safety feature, Iād say thatās more of a planned obsolescence to for the purchase of a new unit or something? I donāt think you guys have done that intentionally, but maybe you just arenāt aware of how battery technology works and best practices related to them? Because what youāre doing right now is about the worst possible decision to make for battery longevity. Please reconsider this design decision.
Hey guys, just a quick note here to let you all know that battery depleting while powered off is normal behaviour, if you have noticed an increase in depletion on the current firmware this does not indicate hardware issues and improvements will be made in future firmware updates. Thanks
This behavior will destroy the battery. Itās impractical to expect the user to charge the battery every week, especially during the winter. Leaving the battery at a 0 charge state, which is basically what you are saying is normal behavior, will wreck the battery in a very short period of time.
Are you guys prepared to cover the cost of battery replacement? I suspect notā¦ As such, it doesnāt make sense to have the unit discharge itself at such a high discharge rate when off.
Hi Josh, thanks for your concern, I assure you the battery will not be destroyed. There are safety precautions in place to prevent this. Again, as mentioned, we are working on new firmware, once it is available and your device is connected to wifi, you will see a notification to perform the OTA update.
I canāt turn the device on anymore on battery.
It turns on only with the cable but after few seconds it displays ālow battery voltageā and it shuts down.
The battery doesnāt seem to charge because after few hours on the power supply it still have the same issue.
I should have the latest firmare, unless thereās been an update in the last 6 days
With regards to the battery being destroyed, thatās literally whatās happening right now. There are no safeguards in place to prevent it. Draining the battery to zero and letting it sit there for an extended period of time destroys batteries faster than anything else and you say thatās expected behavior currently.
Are there any news @Tracy@dekunu-staff ? Last Saturday I made 3 jumps, and I turned off the device with still 60% of remaining charge.
Now I tried to turn it on to have it ready for tomorrow and I found the battery at 0% (6 days have passed).
As already mentioned, this problem irreparably ruins the battery !!!
Iām starting to get tired of this kind of problem ā¦
There will be improvements in the next firmware iteration, it is a big launch that requires a lot of testing, hopefully it is not far off, your device will let you know when it is available
Charged to full last weekend while unit was off. It was definitely at 100% battery charge, turned off, in my bag.
Pulled it out this morning to go jump. Dead as a doornail 0% battery.
No fix. No response. Nothing. Getting pretty tired of this. You guys keep promising a ābig firmware updateā but it never materializes. The last firmware updated added features nobody really asked for. I think people are mostly asking for you to fix the problems with the unit. When can we expect a firmware update that fixes problems? āSoonā isnāt a when. Because itās been āsoonā for the past year or more. Just be honest when itās going to be released. If itās going to be awhile, I need to find another altimeter.
I thought I was having a similar issue, but it turns out my alti was essentially just in sleep mode, not fully off. When I hold down the power button, and confirm āPower Offā it then holds the charge when not in use with no issues. Not sure if thatās how youāre going about it, but throwing that out there.
