Fenix 6S Pro Solar dramatic battery drain since 12.20

I am having the same issue since 12.20.  Had 100%, ran once, the next day completely dead watch.  Now I charged yesterday, had 6 days left this morning, hour later low battery warning.  It feels warm while charging.  Not sure I recall that being the case always.  I am resetting the settings right now.  I see that from your experience that made no difference. 

So it may not be a hardware problem if we are several encountering this horrible battery drain since 12.20

i hope Garmin is working on that because this is not acceptable

reset does nothing, indeed

Had the same problem on a recently purchased 6X Pro Solar. Only RMA solved it.

I reverted back as far as 5.04, did not solve the problem. After many resets, I did not even bother to setup BT or WiFi, just put the watch to battery saver, still insane drain :/ New watch is good with 11.20, disabled the heck out of Software Updates!

Hello

what is rma ? You returned the watch to Garmin ?

Return To Manufacturer, so yes. The replaced it with no questions asked.

I will do it in January. Too Many risks to send it before Christmas ^^

same here, I don't think it's HW issue, some update broke mine same way. One run, it seems ok, 1 day later, it's completely discharged. I want my old FW back, but it's nowhere to be found :( thinking about copying the whole content of the watch to a separate folder after every single update I do with Connect

I think this is SW issue too. I want it to be fixed asap.

i do not understand why Garmin does not let access to old FW

Hello

the firmware 13.10 does not solve the problem. The battery drain in incredible even without any activity ! (20% lots by night !) . Please Garmin, could you I investigate the problem ? 

for me 13.10 is much better now. F6X Pro Solar
