I'm getting some strange activity on the watch:

When it runs out of battery and shuts down, I place the watch on the charging cradle while it is off, and it starts to charge as normal. It slowly charges up to 25% as usual, and then suddenly it's at 100%!!
When I boot up the watch it is at 100%, but then starts to lose charge very quickly. It's almost like the battery has become uncalibrated. I have tried running it down and then fully charging it while off and leaving it on the charging cradle for hours etc, but no help.

Anyone else with this problem, and any suggestions? (Can't send it in for warranty repair etc... cos I live in UK where they don't sell it, so had to buy it off eBay, it's a W280A which had an AT&T sim in it)

I think I may have fixed this, I'll have to wait and see how long a full charge lasts, but for the first time while powered off, it charged from 1% to 100% by 1% each time, I know because I watched it - it's been driving me crazy! So something had screwed the calibration of the battery it seems!

The fix was to keep the watch on until it powered itself off with no battery. Then try holding down the centre crown and turning it back on again - mine would get to the Google Circles on the boot animation, and then black out again - and I did this repeatedly, with the LG logo flashing up, then Google, then the circles, then it turned itself off again - so I knew there was more battery there (yes, I know these batteries keep a reserve so they are never fully discharged, and it's not good to take them all the way down, but I was only getting the thing to charge 20% or so before it showed 100). So I thought, how to keep the screen on, I can't keep turning it on again and again.

So I put it in fastboot mode, hold down the centre button and the lower button and it will bring up the fastboot screen - and I left it with the screen on, which seemed for like hours. When the screen finally went off, I tried turning it on, no LG logo screen, tried booting into fastboot, nothing - the watch was truly dead! So I held my breath and placed it on the charger. After a few moments, the white flashing ring appeared and 1% appeared in the centre, yaay!! I then watched it, repeatedly every few minutes pressing the centre crown to check the battery while it cycled through every percent until it reached 100! Now the watch is on and I am monitoring the discharge. I will let you know how it goes (before I couldn't get more than 4 or 5 hours out of it with all sensors off!)

So for all those that are getting exceptionally poor battery life out there, your watch may be lying to you - when it runs out of juice and powers off, before charging it again, turn it on again and again until nothing appears on the screen, or enter fastboot/recovery and the let the screen drain the rest of the battery. Obviously I take no responsibility if it messes up your watch.

I can confirm that this has fixed the problem. I'm getting easily one day out of the watch now, even after going out for a 2 hour half marathon mid day. This watch rocks now!

I tired your procedure but no luck

Also can confirm the fastboot drain worked - took 3+ hours (I went to bed) on high brightness but then recharged in about 2 hours and has 60% left after 8 hours use (battery saver and I turn screen off manually).

Thank you Admisi I might try this for other devices forgetting where the bottom of the battery is. Good stuff.
