Battery is really bad after Pie update

[Freeze Time]

I have an LG V30. I updated to Pie a little over a month ago and the battery is much worse now. On Oreo, I could get a full day with a good amount of use before I would have to charge it. At night, it would drain like 5-7% but now, it drains 40-50% overnight and I can't go more than a few hours of use before I have to charge it. I have googled this and tried all the fixes and nothing works. My last resort is to do a factory reset but I would have to back up all my info first and I've been told that that might not even work. HELP! I thought new OS were supposed to be a good thing but Pie has been terrible for me. What can I do to get my battery working normal again?

Any tips or suggestions?

No, but I didn't want you to feel ignored.

I've heard awful things about updating to Pie, and am actually glad Motorola changed its mind on my phone [Moto Z² Force Edition] getting it.

I'm guessing that no one's replied because they didn't have anything useful to post.

If no one comes along with other ideas, I'd see if your battery is user-replaceable [probably not...easily, anyway] and, if it is, try that. It's possible that this is all a coincidence, and the battery is going out.

If all else fails, do the dreaded factory reset.

Battery is not replaceable. Why would they release an OS that makes the battery worse? Hasn't Pie been out for like a year too? LG is usually always like the last company to update it's phones so how is the OS still this bad after that long of a time? No one else here has had this problem or has found a solution? Pretty sad if true. There has got to be some things I haven't tried before I have to factory reset.

You can step through every battery-related setting in System Settings, adjusting things like battery optimization and battery saver.

Under 'Battery' [on my Oreo] there are several settings, along with a list of apps; choosing each app allows for setting its battery optimization options, etc.

Just keep in mind this may not be a Pie issue at all, but a battery problem that happened to coincide with the update. You could get a quote from a trustworthy repair shop to see about getting a new battery.

I find it hard to believe that the exact same day I upgraded, my battery started to die. I guess it's a possibility though. I have never had to mess with any battery related stuff in the settings but I have tried some of those things already. I can do extended or maximum to save battery. They both turn off a lot of cool things that I like having. I think it's definitely the pie update. The lack of responses here means I probably have to do the factory reset.

I've had zero issues with my V40, after the update. It took a couple days for everything to settle down, but since you've had it for over a month, IDK.

Do you ever run the Smart Cleaning program? If not, it could help.

I did not. I will download that app right now. Thanks.

**EDIT** which one? The AVG one? There are a bunch of them.

 

[PitCarver]

None... should be in settings, under extensions.

Thanks. I found it and optimized the phone so I'll see how it goes.

Didn't work. My battery went down 40% overnight. Maybe I should just start deleting certain apps and see if that works? Run the AVG optimizer? So lame that Pie has ruined my battery.

Android 9 itself doesn't do anything bad to the battery: I'm on 10 now, but used 9 for a year and the battery was no worse than 8, perhaps marginally better. However, that's not to say that a bad implementation by the manufacturer for a particular model can't do this, it's just noting that Android 9 itself isn't intrinsically bad for battery.

What I would suggest is looking at your battery stats to see what is eating the power. Unless you live in a fringe signal area 40% overnight is crazy, so something is consuming too much. It might be a bad OS implementation, but it could be that you have an app that's not really compatible (even though 9 has been out for over a year - not all apps will have been updated at all in that time, and those that have won't be tested on all devices). If your system's battery stats won't tell you anything then try a third party battery monitor.

(And yeah, I call it "9" because "Pie" has always sounded stupid to me. Probably in part because being British "Pie" doesn't imply a dessert, and if someone says "pie" without specifying it's almost certainly savoury, as in "pie and chips" (where "chips" means "like fries only thicker cut", not thin fried potato disks that come in an environmentally dodgy plastic bag, which we would call "crisps". What was that saying about "2 nations divided by a common language"? )).

Unlikely, yes. Impossible? No!

I could tell you stories of unbelievable-sounding coincidences that have happened in my life. You'd swear I was making them up. Instead, I'll just reiterate that it's -possible- you're dealing with a bad battery, one whose manifestation of symptoms happened to coincide with your update.

Can you leave it a bit longer? 2% per hour phone idle isn't crazy (in general, not familiar with this phone), and I assume you were texting during this period (I rarely spend that long texting so can't say whether that's reasonable, though I had no problems with Chomp and Android 9 myself). You talked about a large drain overnight so what uses power in standby is the question there.

I have no idea but the battery drain overnight at 40% is ridiculous.
I just talked on the phone for 15 min. When I started, my battery was 77%. I checked it once I got off and it's now 61%. That never happened before. Nothing even close to that. I would need to talk for almost an hour for it to go down like 5%. So frustrating. I will just run the AVG app. It won't make things worse.

 

[Hadron]

I don't know that I'd expect AVG to help though.

If you charge it, leave it in standby for a few hours, then you should be able to see what's using the power (this is the same as the overnight drain test).

If you can't identify anything in particular it might be worth backing up and trying a factory reset. The cleanest way to do a major OS update would always be to do a reset and start clean, but obviously you can't have over the air updates doing that to everyone! But you can have odd bits of data that are incompatible between versions which cause problems after an update: it's unusual, but everyone's phone is different and it does happen in some cases. So when there are unexplained performance issues after a major update this is always worth considering. No promises, it could be that LG simply released a bad update for this model, but it might also be that something in your specific Android 8 setup didn't translate well to Android 9, in which case a reset could help.

Okay. I will fully charge it tonight and then post a screen shot of what it says in the morning.

Okay so last night, I installed and ran AVG. I then deleted the app and reset my phone. I charged to 100% before bed and woke up about 6 hours later and the battery had only drained a normal 7%. I'll keep monitoring the phone but so far so good. My other problem with delayed notifications is still happening though. It's been that way since my 2nd Oreo update. What I mean is that if my phone is in standby mode/sleep, I don't get notifications right away. Pretty much anytime I go to check my phone, liek 4 emails pop up/words with friends and other notifications go through. Sometimes as long as 12 min my emails won't show up when in standby. I have already gone into the settings and put them as priority and it doesn't help. I was hoping the new OS Android 9 would fix this issue but it hasn't. I have learned to deal with it. Overall, I am not really liking the LGV30 and it was the most expensive phone I've ever bought.

Have you tried excluding your email app from battery optimisation? It might be that it's being put into too deep a sleep state (though you'd hope it would be running a service that would still be working in the background).

It won't let me.

Battery drained again big time last night. Here are the pics.

Hmm, so the system battery info is only accounting for 1/3 of what it says was app usage. But "phone idle" at 35% is weird, especially since your mobile signal looks OK (if it was marginal then you can get a lot of drain from that).

All I can think of is try a third party battery monitor (GSam for example) and see if it can give you better info, or else try backing up and resetting and see whether that improves anything.

Not being able to exclude the email app from battery optimisation is poor, but that must be an LG thing. However that's not the cause of the battery drain, as excluding it could only increase battery usage.

I think the best thing to do is just backup and reset. This guide is will work correct?

https://www.hardreset.info/devices/lg/lg-v30/faq/backup/how-to-back-up-data-in-lg/

That will back up all my text messages and call history too? Do I need to move my pitchers to my SD card?

 

[Hadron]

I don't own a LG so cannot say what information an LG backup will back up.

Do not leave pictures on the internal storage: copy them off the phone, or copy them to SD and remove the card before resetting (to make sure it can't wipe the card).

I personally have separate backups for messages, keep a VCARD backup of my contacts, and back up my entire internal storage to a computer. I'd probably also use a third party app backup like Helium as well as the manufacturer or Google's backup. You'll guess from this that I prefer to play safe and would rather make 2 backups than rely on one which turns out not to include everything I consider important.

I've been putting off the backup and restoring but the battery issue is not going away. Do you have any idea what could be the reason especially when the phone is in not being used? What could be draining a battery that much overnight?
