[LG V30 Questions & Answers] TheDannemand:
Thanks again.

I finally had time to look at the stat files this morning. I've done three overnight runs now, with power drain ranging from 0.4 to 0.7%. In all three cases, the phone spent the entire time in in Deep Sleep, except 5-7 mins. That's actually not too bad.

Over half the wake time is generally spent by various Google service, in the last run (0.7%/hr) including a Google Play Protect scan, which caused 13MB of network use. As much as the busy-ness of Google's services irk me, it's an old and familier enemy, and I know that I've pinched them as far as I am willing to go: Play Store is set to only notify (I'll update when I want); I want my Gmail synced; and I've already disabled Location reporting and all Google's other numerous reporting settings (there are a LOT of them when you dig through the Google services menu). The only new revelation is how busy Google Music and LG Music are in the background -- I never use any of them, but I also don't want to disable them.

It's pretty clear by now that by far the biggest drain with the V30 is the radios (cell and WiFi, as I've turned off GPS, Bluetooth and NFC): With the screen off and very little network traffic, there is no way the CPU alone could drain 4-5% in 6 mins of wake time. And the phone lying in our living room (closer to South side window where B12 tower is located, and closer to WiFi router) dropped drain to 0.4%/hr, compared to 0.6-0.7%/hr in our bedroom (closer to North side window with B2 tower).

I always knew about the impact of the cell radio, which is why I used Smart Radio in the past to switch to 2G when I was home. But the V30 radios seem particularly power hungry. Combined with the fact that my signal is generally a bit worse than my old Nexus 5, I am even wondering if there is an issue with my V30 unit. Something else to ponder.

Cell reception in our concrete brick apartment is always the biggest challenge. Before V30, both my wife and I were using Nexus 5 the last 4 years (yes, FOUR years). Best phone ever: We used it on both T-Mobile, AT&T and Sprint networks. The N5 doesn't have B12 (700MHz), which is why we left T-Mo, since it was their only low frequency band. Smart Radio was a must during our time with them. AT&T was fine on the Nexus 5 with their B5 (850MHz), and so was Sprint with their B26 (also 850MHz).

Being a brand new, high end phone with B12 support, I was surprised the V30 didn't solve our T-Mobile reception. But T-Mo's setup around here is a mess, with four different towers and different bands around our home, all of them quite weak, and only one being low frequency (B12 towards the south).

If the V30 H932 had had CDMA support, we would be back to Sprint (TPO MVNO). But since it doesn't we're now on AT&T (Red Pocket and H2O MVNOs), which is OK -- but strangely, not as good as it was on the N5 (as of a couple years ago) despite the fact that we now can use their B12 in addition to their B5. North side is all B2 (1900MHz).

In addition to the reception and dropout issue, all this obviously affects battery use: The cell radio works very hard to maintain signal here.

I may look into 2G or 3G at home. Now that we switched from T-Mo postpaid to AT&T MVNOs, we no longer have the benefit of HD Voice/VoLTE anyway. But since we don't have Smart Radio on the V30 (H932 is not rootable) switching between 2G/LTE is a hassle.

You are absolutely right that indiscriminate disabling or ADB uninstalling of system apps can be risky. It is good that you mention it. I am fully aware of the risks and have approached it step-by-step. Also, I am prepared to factory restore if need be. I would never mess with my phone unless I knew I had time to fix it -- and fortunately I still have my N5 as backup. But again, those are excellent points to mention.

Reducing RAM use is only a minor concern for me: While it does speed up some tasks by saving memory swapping, Android is pretty good at managing available memory. The same is true for internal storage: ADB uninstalling has little affect here, and my V30+ has plenty of space anyway.

For me this is ALL about getting rid of apps and services with high wakelock TIME. I remember many years ago I would obsess about wakelock counts, until I realized some of the services that caused many wakelocks didn't actually spend much time. Basically on the V30 I'd already identified and uninstalled the worst battery suckers, except those Music apps.

Now it's a matter of balancing how much further I want to go (if any) with usability of my phone. I'll probably turn GPS and Bluetooth back on, as long as I can keep recharging down to every 3rd night.

Thanks again for your help. I've gotten a newfound appreciation for BBS, which I had not used in several years. It still lives up to its name by providing more detailed stats than any other battery app I know.
