Random rapid battery loss
-
I have had my Suunto 7 for about 6 weeks now and am really enjoying it. The battery life is generally very good. I usually get about 1.5 days. Compared to my Fossil Gen 5 which barely made it through the day it’s fantastic. There’s one thing which is puzzling me though.
Every so it suddenly starts draining very rapidly: more than 5% per hour. And there doesn’t seem to be any particular trigger. Yesterday it was when I was sitting in an Indian restaurant! See attached image. I can’t see what is causing the drain. If I reboot everything is fine again for a few days.
Anyone have any idea what can cause this? There was a similar thread a while ago which mentioned YTMusic and Spotify but I don’t have either of them.

@Graham-Nind Happened to me the same since last charge but not with abrupt decrease as you. On my case I have a high usage from Suunto Wear Services (18%) even when I not did any activity in this lapse and the bluetooth (or any other connection) was off almost all the time.

@Graham-Nind it’s a strange one, mine only drains the quickest in the first 10% drop from 100 to 90 after that it’s stable all the way down until it hits 30% the drain becomes quicker. One strange thing about the S7 is that each battery cycle gives slightly different results. In your case it seem like watch idle nigh have something running in the background, try to clear cache in the wearos app on the watch. I do this regularly to all apps. Clearing cache can help.
I also find that the best power efficient face to be marine.

@BinoWorld-UK Thanks for the suggestion. I’ll give it a go

@Graham-Nind it’s just wear os background processes. your watch will do this sometimes - think that some of the coding is a bit buggy and instead of waiting to do some intense data pulls/processer heavy functions (like checking for updates etc) while its on charge, it can do them at inconvenient times.
Change things like play store updates to manual and things like that - as I found that was often the cause of sudden battery drains - it would be checking for updates, downloading them and installing them all while I was out and about draining my battery, instead of waiting until recharging and doing it then. So I would then just trigger those sort of checks like once a week when the watch was recharging. -
@Jamie-BG Thanks for that. I’ll give it a try. Shame there isn’t a setting that allows you to have automatic updates but only when charging.
-
@Jamie-BG I wondering if removing the weoaros update 2.37 can help the issue?? What does this update add anyway? Not much to be honest
-
My bet is that the rapid drop is caused by the bluetooth connecting. 5% bluetooth seems a bit high when watch idle is 9% and android system is 6%. I also experience this occasionally, but I do not know why it happens. Maybe the watch has temporary problems connecting to the phone?
-
@aeroild from WearOS side I get some weird behavior, very exporadic, that could be possible that. Sometimes I turn on the Airplane Mode and the Bluetooth still ON, but only happened to me few times in almost 2 years.
-
@aeroild I must agree because sometime I also notice that my phone cannot connect to the SuuntO app which means the Bluetooth was lost and it’s constantly searching. It’s a buggy wearos!
-
Thanks for all the suggestions. I cleared the Wear OS cache and turned off automatic Play Store updates. Since then there haven’t been any random rapid drops. Also, Bluetooth usage has stayed at 1%. It may be a bit premature to say it, but the problem does seem to have gone away. So, again, thanks everyone for the suggestions.
