Can't speak for the OP - but for me, no on both devices - totally stock. The latest one, box fresh on Friday! Also, the phone is most definitely OFF, and not just sleeping, ie, I press the power button & choose the "power off" option from the pop up. Unfortunately there's no way to really test this, by pulling the battery...

Why not just leave it charging when it's off..

Nah - I tested it multiple times on my first phone. One time I left it for over two days and the battery went from "reporting 100%" to being under 10% whilst turned off!! Also on all the charges - I deliberately would leave the phone on the charger for multiple hours, even after it was reporting 100%, as I had the same suspicion. Often I'd leave it to charge overnight...

I have never had this issue with any other phone, or with my Nexus 7 (which I have subsequently tested in this respect, and it is perfectly capable of holding a charge whilst off)

It's not so much that it's a practical issue, it's more that I'm worried that it might indicative of a larger hardware based defect, and I'm not happy spending my hard earned cash on faulty goods.

If it's a very common complaint/fault then I won't bother to RMA the second one, but if I'm just ridiculously unlucky, and very few people are experiencing this totally weird behaviour, then I'll take my chances on a third...

Also, I don't think it's too much to ask to be able to turn my phone off to prevent it from losing any more charge. I can think of a plethora of scenarios where this would be extremely useful...

I'm now convinced of three things.

1. Android 4.2.1 can not properly read the battery state
2. Shutting down the phone does NOT do that, but rather puts it in to a hybernate mode that still requires battery charge
3. There is a fundamental design flaw in the phone that part causes this.

Most mornings I find my previously shut down at 100% charged phone at only 80-85%, though occasionally it is as high as 97-99, but not often.

Oh and my ROM is stock, my phone is not rooted.

I agree on all counts apart from the first, as my nexus 7 and my Mum's Nexus 10 behave totally normally in this respect, both on 4.2.1 and 4.2.2 (both stock/unrooted, although the Nexus 7 was rooted/bl-unlocked for a time).

Also, I don't believe it's a miss reading of the battery state, as I often leave the device charging for multiple hours after it reports 100%, by which point it simply must be fully charged. What's more - if you leave the device off for long enough it will fully discharge! The craziest thing is that the phone's battery seems to drain quicker when it's 'turned off", than when it's powered on and sleeping. Seriously WTF.

It must be something to do with either the LG hardware, or LG specific code in the Google ROM. Obviously the phone is incapable of properly shutting down, which is pretty crappy for a so called "flagship" device. As someone who likes to have full control of their device, I find it more than a wee bit irksome, that I don't have the ability to completely shutdown my phone! This is also where the irremovable battery is annoying, because there's no way to test whether it's a hardware or software issue, although I guess I could try a custom ROM and see if it still happens.... however I don't really wanna root & rom if I'm going to RMA it....

I'm really interested to know how many other people have this defect and don't even realise it, because their phone is either in use or charging! I find it hard to believe that I could be unlucky enough to have got two uniquely defective devices in a row...

I'd really appreciate it if people could check their devices for this issue, both on stock and custom ROMs, see if we can work out whether it's HW or SW related...

You could try powering it off with the bootloader. After you power off normally, hold power and volume down, when the bootloader menu comes on use volume keys to select power off and power button to confirm.

I'm hard pressed to believe the battery in my device would fully discharge if left off, when the phone arrived the battery wasn't dead, I got about three hours of solid tinkering before it died.

That's a good point. Mine came out of the box at about 80%.... hmmm. It could be that once it's first turned on it won't turn off again... this is such an odd issue! I shall try powering off from the bootloader next time, I'd still love to hear if other people's phones exhibit this anomaly though...

I'm aware that it's hard to believe issue, but there's only one way to find out...

I'm also very curious to know if loading a custom rom might solve it. I'm far less concerned if it's a software issue, I just don't want to have spend 250 on defective hardware.

I'm 100% stock, no Custom ROM nor kernal (kernel?) and my phone WILL discharge if left unplugged and "off". Happens every time I come back from overseas. Fully charge it up on the plane (even left the phone on but in airplane mode to 100% thinking that it was a misread of the battery level when the phone was "off") and still the same issue... turn it on a few days later and the charge is down to 75% or so....

I thought I was losing it... but I'm not the only one...

Ha - me too! With the first one, I actually went into a weird sort of denial, where I kept convincing myself that I must of got it wrong, it just seemed so absurd! Eventually I put it to the test (multiple times) and realized that my memory wasn't as bad as I'd been trying to persuade myself and the phone was in fact discharging when "off".

Anyone else?

Just got the update to 4.2.2 and have got my fingers firmly crossed that it's now a squished bug... although somehow I think it's more likely an LG/hardware issue...

What you could try to do it charge the battery to 100%, hold the power button for 10 seconds until it fully shuts itself off. Leave it overnight and see the battery level is at the next day.
