Sudden battery drain After 8 months - Moto 360 2015

Hi.
I've had the Moto 360 2nd gen since March and the battery has always been quite good, lasting from 7am to 10pm with 40% left.
Now, all of a sudden, it dies at 5-6pm... I didn't change anything and the last update was on Oct 01.
This is happening since 3-4 days. I have tried to unpair and reinstall but no change.
What could it be?!??
Thabk you.

Battery Drain after Nougat update

So last night after a long dilemma i updated my Z5c from MM to Nougat and today the battery was just horrible.I updated at 95% and after the update i had 75%.With around 2hours screenon time i went under 15% ,light usage.
Is this because the phone has to adapt and the update was so recently done, or nougat battery management it's just this bad compared to MM?on MM i was able to get 6-8 hours screen-on time with a charge.
What should i do?
A:Roll back to MM.
B:Wait for the phone to adapt to the new software.
C:Try to do a repair with PC companion?
Sorry if i asked anything stupid ,i recently got this phone and im still a newbee about it.
Thanks
I have the same issue
Do get you some help, we would need more infos.
Like, Did you root it?
Which version is installed?
Dirty update or clean install?
Battery is fine with mine. 8 hours idle and just 3% drain
Could you check the battery with AccuBattery . I bought a phone in late October 2015. I'm charging it every day. Until now it musit have been around 530 charge cycles. AccuBattery says that current capacity of the device is around 2009 mAh. I also checked the capacity of the battery with this Voltage Current Detector Power Tester. When charging the device from 1% to 100% it measured 1800mAh. Almost the same number gave me the AccuBattery for that specific charge. I have a feeling that after the last update, the phone last less (I did master reset). A friend of mine, who bought the phone a year ago says it's Z5c last longer after last update. AccuBatery also shows that his capacity is around 2700 mAh. I'm thinking to send my phone to repair but I doubt I would have any success.
Try AndroPlus kernel. It solved my problem

Battery life suddenly dismal

Just today my watch barely lasted half the day, compared to it usually making it past bed time. Nothing changed from today since yesterday. Anyone else? All up to date too

Battery charge after Pie update

Hi,
On Friday evening I've updated my H9 to Pie.
I always charge my phone during the night to have it ready for the morning.
On Saturday morning I found it at 98% of charge. I have rebooted it and put in charge another time. This time it raised 100%. During the day the discharge has been good.
This morning another time it was at 98%.
Why? Is it a protection for the battery or I have issues with Pie update? What I can do?

Moto G8 Play Battery Life Suddenly Dropped

I've had my g8 Play for a few months now and I've been relatively happy with it. The battery always lasted me longer than the full day, probably 30-36 hours of normal usage.
One day, a couple of weeks ago, the battery was down to 5% by early afternoon. I assumed that I had forgotten to charge it overnight as is my usual practice. Nope. It's now only getting 5+ hours on a charge.
I installed Accubattery and it reports that my battery capacity is still fine at 3941 of a rated 4000mAh rating. It also reports that I'm getting a full charge.
What has me worried is the battery drain of my apps. Chrome, for instance, is drawing 649.3 mA. That seems pretty high to me, but my top five apps are all quite similar.
Accubattery predicts that I will get 7h49m of normally use on a full charge.
I did a full factory reset but that did nothing.
Can anyone tell me what's going on?

There is a G8 play forum

Sometimes OTA updates don't quite install correct or something and reflashing the firmware will fix it.
Lmsa is pretty easy to use.

Thanks Shadow. I'm currently traveling and only have my Linux laptop with me. I'll give this a shot next week once I'm home and have access to a Windows machine
Interestingly enough, the situation has spontaneously resolved. As of a few days ago, I'm back to normal. I unplugged my charger 16 hours ago at 80% charge and I'm now showing 1 day + 5 hours remaining. It must have been something that updated in the background that was causing my grief. Accubattery now reports that Chrome is drawing 321 mA.
