Battery Suddenly Massively Draining Overnight

[kbboykin]

For the last two nights, my GW5 Pro has had massive overnight drainage.  The first night I went to bed with about 60% left and woke up 2 hrs later and it was completely dead.  Last night I went to bed with about 70% and woke up to 29% after 4 hrs or so.  The percentage used don't add up and I have not changed anything.  I used to get 2-21/2 days on a full charge, but not anymore.

Two questions strike me as I look over you attachments: 1) do you normally get around 20 hours (or slightly more) from your watch, and 2) are you sure that the GPS is not operating all the time?

My GW4 classic gets 2 days, 20 hours, but I never use the GPS (phone gives me location data).  Your percentages of battery use over the reported 12 hours and a fraction of use are in line, cumulatively, for the amounts of battery use over what my watch has used in the last 33 or so hours. 

I know you have a GW5 Pro and I  have a GW4, but despite a chip or two difference plus a battery that is to die for, they have basically the same guts as far as the OS is concerned. I have tweaked some apps to give me ~6 to 8 hours of additional power for each charge cycle, but I do not run an AOD, or the GPS. These two functions can chew through the battery unrelentingly.  

You probably are not using the AOD, but you could very well have the GPS on and not know it. I learned to turn the GPS off when I got my 45mm GW3. I could get almost 3.5 days out of that one (I was trying for 4 days!). When I got the GW4 classic I replicated most of the same things I did with the GW3, but because it was Android I had to turn off several apps to cut down in Android app back-chatter. The result was the aforementioned 2 days, 20 hours life.

After the 4th beta installment I saw a huge drop in battery life. After searching I found that the GPS was suddenly running again, which may have resulted from updating to the 4th beta via the watch itself. It needs WiFi to do that (I keep that off also) it may have activated the GPS in the process to verify location. I barely got a day. I looked around in the watch, turned off the GPS, let it learn my usage habits and voila - 2 days, 20 hours again!

The docs on the GW5 Pro say you should expect up to 80 hours out of the GW5 Pro battery. I suggest verifying your "Connections" for WiFi, and also see if the GPS is powered up. You could/should also clear the cache on the Wear app, and do a power cycle of the GW5 Pro. Hope this helps.

The most I ever got so far from my GW5 Pro was 2 days, 18 hrs.  It is the LTE model, but that is definitely turned off (I turn in on only when I know I'll need it).  I did have WiFi on all the time and turned that off, and yes, GPS(Location?) was on and I have now turned that off.  I will see how it does now.  During the day, it was so-so, but what I couldn't figure was why in the **bleep**, it nose-dived at night!

I have had the same thing happen to me, several times with the GW3, and twice with the GW4 classic. When it happened I did the same analysis, and usually found nothing. But I have to say that the GW4 classic has been rock solid as far as battery use since I squared it away after the installation of the 4th Beta. The 5th Beta has been relatively uneventful, which at first had me worried that I had missed something, and strangely disappointed because it was so smooth. 

I hope your problem straightens itself out for you.

I didn't see anyone post this yet. I also was having battery drain issues and I turned off 2 things and now it's gone. Automatic activity tracking and raise wrist to wake. Haven't had the time to check which one was causing the drain but also on watch 5 pro lte so maybe it'll work for you too
