Has anyone noticed decreased battery life after the 4.4 update?

I think I am, unrooted, virgin phone, but I've just gotten the phone yesterday so I cant really compare it to before the update. But it's draining much faster than I expected.

As of right now I'm at:

Usage on batt: 5h 24min

Expected time to use: +7h 10min

Last 3 hours in use: 25%

Also has anyone had any success with getting into the bootloader? Where can I follow the progress?

I created a thread here: http://xdaforums.com/show...php?p=51646677

Let me know if there's a better place to follow!

rooted d801 with 4.4.2 prompting OTA software update

I just bought this G2 and it came rooted and is running t-mobile's stock rom of 4.4.2. I have nova & xposed installed & working excellent. Since I got it I have had a downloaded/pending software update notification in the tray that won't go away, it's a (149.6 mb size update) which says it's an android software system update from T-mobile. Not sure what its for, but a little nervous click install & reboot since the phone is running smooth and battery is great as is. Is it safe to install or do I run the risk of looping or losing root? If I shouldn't update it, is there a way I can clear or rid the notification tray of the software update prompt and prevent it from coming back? or delete the downloaded update? thx in advance.

Updated to D80120e and Rooted

Just updated my rooted LG G2 to D80120e (with Knock Code) via LG's Mobile Support Tool - OTA didn't work as I was already rooted. (Thanks LG for allowing us to update even with a rooted device). Lost root, but instantly re-rooted with Geohot's Towelroot - quick and easy.

[T-Mobile LG G2] demoncamber:
Did it wipe your internal storage as well?
[T-Mobile LG G2] Chinauser:
No - everything was saved through both the update and rooting. No issues so far...
[T-Mobile LG G2] FoneWatcher:
Which version of towelroot did you use?
[T-Mobile LG G2] TheCoutures:
Did you loose knock on?
[T-Mobile LG G2] Chinauser:
Thought there was only one version of Towelroot - in any case, says "welcome to towelroot v1" when I bring it up on my phone. (In addition to the XDA thread above, see http://www.towelroot.com/.)

I was also coming from D80120a (rooted with towelroot), but the LG tool said something like "LG is pleased to make the D80120e update available for you phone" or some such, then I clicked on Start Upgrade on the left bar. In an earlier attempt I tried to install the drivers, but it said they were an older version (v8?) than I already have (v10) so I skipped it.

Hope that helps.
[T-Mobile LG G2] FoneWatcher:
Thanks - I restarted my phone and it showed the upgrade available via the LG utility.

And there are three towelroot versions. I've been collecting them all, but saw reports that it worked on the G2 since v1, so I'll use that like you did.
[T-Mobile LG G2] Chinauser:
No, did not lose Knock On or any data or functionality - everything seems to work exactly as before the update/root. The only disappointment was that while I can see Knock Code in the Lock Screen setup, as it is grayed out. I think that's because I have VPN installed - couldn't get to the other options (Swipe/Face Unlock) before the update, either. I don't want to uninstall my VPN, though, as I go to China frequently and depend on it.
[T-Mobile LG G2] TheCoutures:
I just rooted with v3 so far so good, thanks.

I downloaded the latest towelroot and it also worked fine after the update.
[T-Mobile LG G2] mannequin:
also, did it fix the infamous audio issues?

P.S. what would be the easiest way to update from 4.2.2 (D80110g) rooted with TWRP to the latest version with root and custom recovery? i don't mind doing whole wipe.
[T-Mobile LG G2] Howie Dub:
I can't comment on the audio issues as I never really used headphones with my phone. Speakerphone seems clearer, but didn't use it all that much either. biggest issue for me was the constant dropping of data on LTE, where I'd have to toggle the network to get data back. Seems to be working okay so far.

Easiest way to get to the latest version would be to use the support tool or pc suite. Follow the instruction in the OP if you use the support tool. You can then root using towelroot and AutoRec for recovery. I'm not 100% certain, but I think you lose Knock Code if you use AutoRec to install recovery. I didn't install recovery b/c I don't flash much and actually like Knock Code. You don't have to wipe anything, but I would still backup anything important. The whole process to update to the new version took me less than 15 minutes, with the download taking 11 minutes (took 45 minutes to download 20a).
[T-Mobile LG G2] mannequin:
i'm assuming updating (from 4.2.2) through LG tool will completely wipe my phone including custom recovery and "sd" card?

regarding AutoRec, i believe Cloudyfa has a custom kernel out already (ver. 1.3) to bring the Knock Code back (can anybody confirm it works without issues on D801?)
[T-Mobile LG G2] ron_e:
Did not wipe my phone. I was rooted and did loose root but reading elsewhere it is easy to get back. Just have not had time yet.
[T-Mobile LG G2] mannequin:
interesting. i have a whole bunch of factory apps frozen and quite a few xposed modules running too. just wondering, if i should do the whole wipe just in case.
[T-Mobile LG G2] ron_e:
I was running the debloated stock ROM by dr87 and have not run into any issues without doing a wipe. Anything that relied on root would not work after the update so something like xposed could be more problematic.

The LG tools said I was up to date even though I wasn't so I had it apply the latest ROM anyways.

Doing a full wipe, when possible, is never a bad thing in my book. I always try to have my important data backed up.
[T-Mobile LG G2] inspron:
The Knock-on feature feels much more responsive and consistent. The previous version Knock-on works only 60% of the time.

Backup just in case, but the LG tool won't wipe your phone, although any apps disabled/frozen through 3rd party apps will have to be disabled again. I had to disable carrier IQ again, but the apps I disabled through the stock apps menu remained disabled.

Does Knock Code work for you?
[T-Mobile LG G2] mannequin:
just to make sure, are we talking about "LGFlashTool2014" tool? according to the guide, it has two modes: "Normal Flash" (without losing the data but no recommended for upgrading?) and "CSE Flash" ("suitable for upgrading or downgrading ROM" but wipes it clean). i'd go with CSE Flash in my case and that's why i'm confused if it actually wipes everything.

[T-Mobile LG G2] pitchdarkice:
i don't recall that it did, which is odd why i was fully booted so quickly. so maybe it isn't really working and i'm imaging things about it having better performance.

update: I just noticed after looking at it again, it was set back to davlik, maybe it never persisted the change

For some reason like pitch mine keeps kicking back to Dalvik too.

Are you rooted as well? If so which rom and version are you running, what means did you use you route.

[T-Mobile LG G2] FoneWatcher:
I got mine from ebay, D80120a, already rooted, but the seller hadn't mentioned it in the listing. No recovery on it, so I don't know what he did to root originally, but he said it 'came from LG" It was working okay and I got it really cheap, so I just left it alone.

Then I applied the OTA update with LG suite to bring it up to 20e (I rely on WiFi calling and wanted the update) and re-routed with towelroot, v1.

Everything is running along fine with ART, but no perceivable difference. I'll be curious about battery life because I'm already used to pretty phenomenal life on this G2:
[T-Mobile LG G2] TheCoutures:

I have Xposed (and HTC One tweaks) on my M7, but I'm not installing it on the G2 because without recovery, there's no fail-safe way to suspend it in case it (or something conflicting) causes a boot-loop. Besides, I don't think the LG interface is as bad as a lot of people seem to be violently reacting to it on the web.

It's sometimes tough on G2 buttons to get into recovery, so I have used this before:

I don't know if that error is restricted a particular version other than D801 (or maybe it's precipitated by a hardware OEM variance) but I never heard any audio artifacts since I had this G2 both on 20a or 20e.
