[LG V30 Guides, News, & Discussion] br0adband:
I run the stock US998 20H on my V30, rooted with Magisk, no modules in use. Hardly anything is really customized I suppose, I do use dark mode wherever possible and I do have the Dark G8 Theme installed from the Play Market. My brightness is always set to 50% unless I'm watching videos (75%) or outside (90%) but I never go higher than that - 100% brightness is bad for OLED technology especially wherever pure white is shown so I avoid full brightness always.

I keep my cellular radio off at home because I only use Google Voice - I don't give out my carrier number to anyone (there's only like 3 people + the carrier that have it) and since I'm always on Wi-Fi at home (Gigabit connection) I have absolutely no reason to have that active. Google Voice does all my voice calls, SMS/MMS, Hangouts (SMS), etc so I'm good there.

Typical SOT? 9+ hours on a charge and that is without using Battery Saver, which I never use, and that is also with a charge from about 88% down to 5% give or take a percentage point either way. The other day I actually got almost 12.5 hours of SOT but I spent a lot of time watching some TV shows ("Billions," a fantastic show, and I basically marathoned the entire 1st season so that was most of the screen on time).

I don't use a lot of things running in the background, in fact I tend to close out apps when I have no reason to leave them in the background whether they go idle or not. I have never thought that using apps like Greenify can help since it's yet another program that does use resources and does require background operation - it's just easier to close the apps I'm not using and be done with it and know for a fact they're not consuming battery.

I use Flipboard quite a bit every day, LiveNewsOn for watching MSNBC/CNN occasionally, Google News multiple times a day, Discord and Hangouts for chatting purposes, not a whole lot else really. I don't do "social media" stuff so no Facebook/etc kinda crap. LG Package Disabler Pro (purchased a long time ago) was used after a clean install of the OS to ensure what I don't need to be there and running isn't there and running.

Only phone that's ever given me this kind of battery life - and I plug in to charge once every 2-3 days, seriously - was a Samsung Galaxy S Active 7 with a 4000 mAh battery, I could run that device for 3+ days with 14+ hours of SOT most every single charge and I really do miss it.

Anyway, I do love this V30 for a variety of reasons but that crazy 9+ hours of SOT on a charge is probably my most favorite aspect so far.

Pics or it didn't happen... ;)

First one was from a few weeks ago with ~9.25 hrs/SOT, the second from a few days ago with ~12.5 hrs/SOT, and again, I don't use Battery Saver at all, if I did, or if I lowered the brightness to 50% or less when watching videos, I'd probably go well past 15+ hrs/SOT without breaking a sweat. The ~9.25 hrs/SOT did have me charging it from my laptop's USB port for about 30 minutes, had to plug it in to move some movie files over to the device so that's why you see the slight rise in the middle there, but the ~12.5 hrs/SOT was done straight off the battery, the charge it had when I disconnected from the charger was 89% so, if it had been a full 100% charge, that would more than likely be close to 15 hrs/SOT. Might have to test that sometime and see if a 100% to 5% run could do that much SOT.

No issues with the stock ROM, no crashes, no force closes, performance is great, I have no complaints whatsoever.
