Re: Hero 7 Black Battery Issues

Hi guys,


First of all I am not a specialist but tech-geek. Today I read about hardware of GP's camera and I found something intresting and suspiciouse in refernce to our battery issues.


GP6 as GP7 have RTC - real time clock. This is a little thing which counting the time.

Acctually it is: PCF85063A


https://www.nxp.com/docs/en/data-sheet/PCF85063A.pdf


This litlle element needs some small power to live. Maybe the power consumption of this "low power consumption " is not really low - this is my theory:


"The PCF85063A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption. An offset register allows fine-tuning of the clock. All addresses and data are transferred serially via the two-line bidirectional I2C-bus. Maximum data rate is 400 kbit/s. The register address is incremented automatically after each written or read data byte."


Q1: The same RTC has GP6 - do GP6 users have problem with battery drain ?

Q2: RTC use internall battery or externall battery - how about in GP7 ?


As said I am not a specialist but maybe this will be a clue to figured out what is worng ?


See ya

Re: Hero 7 Black Battery Issues

I'm returning it and just using my cell phone.  It has done a fine job and realized there was a lot of hype for a crap product (or that's been my entire GP experience) that at least isn't worth the expense for me.  The annoying part is they claim to send out a battery, but will take 3-5 days.  Yet it took 2 days to ship the camera with the battery when I paid for it.  And then the crap about the SD card "may" be a cause too.  I bought it from GP just so I wouldn't have an issue.  

 

Summary, buyer beware.  I'm a very casual user and deal with tech stuff all the time.  This is the worst tech product I've bought with issues right away.  I will not be a future customer of GP and would recommend people look at other options.  I'd like to say I'm an unusual case, but it's apparently a pretty clear issue.

Re: Hero 7 Black Battery Issues

Hi,

 

I just bought a GoPro Hero 7 Black and a battery package (battery and charging station - official). I noticed that after every photoshoot etc. the next day the battery is DEAD. No life whatsoever! So I checked this thread and I have disabled GPS, Voice Commands and Wifi (just to make sure). So now it wont be dead in the morning, but still it seems that it discharges the battery by 3% per 2 hours....which is still unacceptable. My GoPro Session 4 has still charge after 2 weeks lmao.

 

I have tried both official batteries, its the same. 

My SD card is on the supported list - SanDisk Extreme Pro 64GB

I have made the update manually through SD card (since app was just failing)

I have formated the SD card on the gopro (gonna try full format today when I get home, just in case)

 

Any suggestions? If not, going to return it on monday.

Re: Hero 7 Black Battery Issues

Without going through all the detail and rehashing all the trouble shooting that has been going on in the last 100+ pages.  Summary:

 

- some chances that the battery will hold charge better with some use cycles

- after shutting off, remove and reinsert the battery to avoid any unexpected over night battery depletion.

 

Good luck.

Re: Hero 7 Black Battery Issues

Hi, the battery is either good or it isn't  the ones I have tested hold their charge well have 3 tested after 3 weeks still fully charged

as for removing and re inserting makes no difference the drain issue occurs randomly My drains have occured  randomly

wether or not a instant turnoff has occured or not but I do tend to turn off  and on till I get an instant turn off rather thsan a slow delayed one  never has the myth of battery gaining extra power capacity after charge discharge cycles all that does is remove cycles of life from your battery 500  cycles roughly for a battery that is full discharge full charge is one cycle so if you never do this therotecially battery should last thousands of cycles mine gets charged after every use regardless of wether it is only 10% discharged

Cheers,Brent

Re: Hero 7 Black Battery Issues

@brentb57153  I totally understand what you are saying but from my usage and what other have reported, the battery does seem to improve how well they hold charges after some cycles.  At least 2 out of 3 of mine did.  They were all losing about 10% charge every night when I first got them.  This is with them sitting outside the camera to remove the camera from the equation.  After some uses, 2 of them improved to lose maybe 1% every 2 days.  The 3rd one didn't improve much if at all.  I can't explain why but that's my observation and some others have reported this as well.  But do note that this 'weird behavior' only happens for the China made batteries.  My Vietnam made batteries hold full charges for weeks right from the beginning.

 

As for the randomly depletion (full drain) over night, I am still battling that myself and my current work around is remove and reinsert the battery.  So far, I haven't encounter it again with this 'GoPro-specific-feature' work around.

 

Cheers!

Re: Hero 7 Black Battery Issues

Hi did you read my post on the mis reporting of the battery state  by the camera said 84% turned it off and on then it said 100%

other didn't want to turn on then when it did said 0% put it in charger and only took 10-20 mins to chaarge so it wasn't flat at all

both my goprol batts are Vietnam one did actually loose more charge than the other outside camera but only a percent or so

2 wasabi  hold their charge well too I have no issues with the life of batteries whilst actually recording never got a reply from the guy at gopro with regards to camera mis reporting battery level percentage

Cheers,Brent
