I am having huge issues with my battery on my galaxy s2. It drains really fast, 60% over the last 15 hours this night when the phone has been idle. This has been an issue for about a week now; I cannot seem to find a solution? I have tried various roms, wiping and doing a clean install, but the problem continues. Currently using lightening rom 3,2.
Do anyone know what can be causing this battery drain? Is the battery defective??
What apps do you have installed?

That is quite a drain I can see there. The drain might be caused by having too many widgets or having too many applications open. If you plan to put it on standby, do close those apps that are not important to you.
Have you tried rebooting?
I have a stock lightening rom 3,2. no apps installed, except titanium backup pro and opera mobile. I have frozen all kinds of stuff in titanium to try find the cultprit, but without success. As you see, no apps except andoid OS is running. Same drain on villainrom, lightening. Don't know what can be causing the error. Is there some way to check if the phone or the battery it self is to blame?
Try with screen on - normally I think that should run for 6 hours or so. Using that as a reference, you can check to see if the energy stored in the battery is normal. It doesn't look like your OS is staying overly active to me.
Hi bjorninge,
Every time after you flash a new ROM you should calibrate your battery.
Get the app "battery calibration" from the market and follow instructions and please report back whether you can achieve better performance.

I have a similar issue, as was the same with my captivate. I have stock ROM on my GS2 though, the way I got it out of the box pretty much. Android OS takes up most of the battery usage. I don't know what it is. Widgets updating constantly? The constant syncing from Gmail/push email?
Well that's surprising! Awake and Screen On bar is quite low and totally synchronized, yet 60% drain, now I gotta say it's weird.

Unfortunately, I have the same issue as you've described above. I am running on stock KE2 kernel and the battery drain is quite a lot. The 'Android OS' is always consuming a lot of processor time on standby mode.
This needs to be fixed A.S.A.P.!
Download and install the app BetterBatteryStats from Android section, it is a very useful app which will show what Awaking the device from deep sleep and processes too. For me, it was the damn Latitude stuff going on background and wasn't letting the device to go to deep sleep.

Thanks for the tip. I have downloaded the app now. what spesifically should I look for?
You just look under 'Wakelocks' and you will know what apps are causing the Awake, then you could take further steps.
Regards.
Would be great if you could look at the screenshot and tell me if something is wrong. Also, after the battery calibration, I've "only" lost 26% the last 7 hours mostly idling. I don't see anything abnormal in the screenshot I provided :/
Well nothing is wrong imo as everything is very low. You should check those which are using more than 10 mins Wakelock, some seconds doesn't matter actually. And you can post any query further to the original thread of this app, here,

OK, So I'm now back to 12% battery usage (from 100% to 88%) with 17 hours and 30 mins on battery, which IMO is normal.
What did I do? Well, I removed the battery and put the rest of the phone into the stove for an hour on 50-60 degreed celsius. My 98% android OS usage is gone and the battery works as normal .I also had problems with the phone constantly going into "car mode" which is now gone.
I got some tips around the internet that my issues were all related to moisture on the inside of the phone.
I bought a Samsung Galaxy S 2. Very happy with it, but for the battery life. It lasts a day with medium usage. I want to stop that. I thought of two methods: root it and delete any unnecessary apps, like Hubs or use a customRom.
I am new to Sammy, new to Android and don't want to brick my phone or something. Could someone give me an advice please. When I saw the others with 2 days and 80% battery left i was like "Damn..."
Mine lasted 2.5 days, tops, with minimal usage.

~2 days with normal usage for me - since I went to Android 2.3.4 based firmwares (XXKG*); before that it was ~1 day.
About flashing, just read all the thread here about the matter, Intratech's firmware download threads, the CF-Root root thread and others.
They all have good and solid info on what to do.
Just try to figure what needs to be done and most importantly why, take two or three days for that and after your first flash you'll see: Flashing the SGS2 is easy as 3.1415
// EDIT
*lol* jje beat me a bit xD yeah follow his link battery xD
Root your phone, it will do no harm but add some advantages.
And mate, please don't see those persons posting they are getting 2/3/4 days outta battery, it's not about the Standby time, it's about the Screen On time. If you get around 5-5½ hours of Screen On time then you are pretty good, now you can use that in 12 hours, a day or even two days. Besides, just check under Battery usage stats/graph that your Awake and Screen On time is synchronized or not. If you see a lot of Awake bars activity when screen is off then you must have something going on background which is causing the battery drain. To see what is actually running on Background download and install 'Better Battery Stats', it's a damn helpful app to have. Download it from here,
http://forum.xda-developers.com/showthread.php?t=1179809
See under Wakelocks and check which apps are causing the wakelocks and then freeze/uninstall them with Titanium Backup/Pro, if you don't need them.

Why do you need 2+ days of battery life? Do you not have electricity in the room you sleep? As long as I have battery left after 18 hours, I know there will be at least a 6 hour stretch to charge.
What's the difference if you charge it every night or every second, or even third night? It's not like it's a difficult chore.
Hi everyone
So I recently got a S2, upgraded it from stock Gingerbread to stock ICS via Kies, then flashed CM9. CM9 was great, but I quickly noticed worse battery drain than that of GB. I sorted out all wakelocks, now facebook is the top one in better battery stats list and it's only 10mins in a day so I don't think that's a problem. When charging, vbus_present shows up and keeps the phone from sleeping, but that's a normal thing when the phone is plugged, right? CPUspy shows the phone is in deep sleep the majority of time I don't use it, so I assume I have no wakelock problem.
But even then, the battery still seems a bit bad. When in deep sleep with wifi and mobile data off, it would lose around 1.5% per hour; and with moderate/high use (internet with wifi or gaming), I'd be lucky to have it last 3 hours. Charging to 100% from zero takes about 3 hours.
I also tried recalibrating the battery through BC, but haven't noticed too much of a difference.
Recently I found a guide on disabling fast dormancy via the build.prop file. Still waiting for results though.
So, my questions
1, My battery usage seems normal, doesn't it? 1.5% per deep sleep hour is acceptable I guess, but 3 hours of usage seems a bit short. Too short.
2, What effects does fast dormancy have?
1) Totally unacceptable. Mine lasts at least 7-8 hours with high use..
Does your phone heat up while the heavy use ???
What brightness level do you use for the display ???
How many apps do you have that can gain internet access ???
2) By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.
Luckily, Fast Dormancy can be disabled on the phone. For the Galaxy S II, do the following:
Dial *#9900#
Press “Disable Fast Dormancy“
Press “Exit“.
Easy as that!
Thanks for the suggestion I have brightness manual and at around 20%. Wifi is disabled when not used, and mobile data is always turned off unless I need it, so basically apps only get internet access when I want them to. I have also disabled sync for both google and facebook, but fb still pushes notifications to me while it's connected. Is that a major battery drain, and if yes, how to disable it?
Anyways, facebook, instagram, youtube are the only apps than can access the internet. No messengers or anything that may keep a wakelock.
My phone doesn't heat up during normal use, maybe a bit when I do some gaming (Max Payne?)
Also, *#9900# doesn't do anything on my phone. It doesn't bring up a menu or anything like that.
Bump. Guys?

Install BetterBatteryStats (search for it on here/Google Play), might help you nail what's causing the drain.
Yes I did, as said in my original post. After a night the highest wakelock are just around 10 minutes, and that one was facebook. Uninstalling it however had no effect.
Delivered using Nyan Cat's rainbow powers.
Thinking logically, there's got to be something else in those stats (partial wakelocks in particular) that's causing that drain. There's no way having fast dormancy enabled/disabled is either going to cause/fix the drain you've mentioned getting '3 hours of usage'; (I can get 5 & a bit hours screen on with CM9 & variable usage/mostly 'moderate' use) given everything else you say you've tried.
Post BBS logs here if you want someone to have a look.
Edit to add - Also post a screenshot of the 2nd screen in settings/battery, the one that has history 'details' at the top, with the 'mobile network signal' bar underneath the main battery graph.
Here you go: pastebin.com/1UwicChJ
I just registered half a day ago and don't have enough posts yet to paste links, so sorry the phone was only on battery for nearly 2 hours with some light browsing and facebook, but I hope it works.
Anyway, I looked through my running processes, and dsp manager is the only non-OS process running, besides facebook. I got CM9 so it came by default. Could dspmanager be the culprit?

It's a new phone he's got there and I doubt it could be anything battery related itself.
I'm using CM9 nightlies and I get around 9 hours moderate use. It has been said though that a lot of these CM9 builds have battery drain and heat issues.
I use Juicedefender to help with the battery life which seems to work.

About 1/3 of this time was on wifi browsing. The drop is much more drastic if I play games.

A couple of observations. There's nothing that stands right out in the BBS log. The other one is, looking at that graph you've lost ~15% over a bit under 2 hrs. The screen has been on most of the time the phone has been awake (confirmed by the BBS log) if you look at the respective bars. You've also been using WiFi for most of the time the screen has been on/phone has been awake.
Roughly speaking, going by the screenshot, you'd get ~5hrs+/- screen on time if you kept using the phone in the same way you had during that just under 2 hrs, and this is pretty much normal. I haven't had drain issues for ages, so I double checked my details on the 2nd screen of settings/battery to make sure CM9 is reporting these details accurately (screenshot attached). Certainly in my case, this screenshot reflects what my phone had been doing for the just under 5 hrs it had been off charge/since last reboot; that is, >90% of the time in idle/deep sleep. So it probably isn't CM9 reporting these details inaccurately in your case either.
The BBS log & screenshot don't illustrate the problem you talked about in your OP. Now, if I had to take a stab in the dark at what's causing problems when you do have them (and FWIW, I do believe you're having the problems you mentioned in your OP at times), in the absence of any other info, maybe your WiFi router is constantly sending the phone packets (what's been referred to as a 'dirty router' on here before) when you're connected to WiFi & not actually using it. This scenario has been known to cause relatively high levels of drain.
So to be honest with you, based on that screenshot & the BBS log, I'm not really seeing a problem.
Now, if you want to post the same again when you actually have a problem with drain similar to what you described in your OP, happy to have a look at them. But for that ~2hrs covered by the BBS log & screenshot you posted, that's pretty much normal.

Okay, much appreciated so I guess I'll take it from your reply that 5 hours with wifi browsing isn't too bad. Seems okay, but I still find it a bit strange that (in my case) wifi browsing uses just as much battery as games do. I always thought it was a light activity!
Or maybe it wasn't the battery that had a problem, but that I set my expectations a bit too high. I came to this S2 from a BlackBerry 9700, whose battery would last half a week with very frequent use. But anyway, I just got this phone for a week, so I consider myself a pretty heavy user. Probably when I get familiar with it, I won't feel the need to play with it every five minutes and battery will last a bit longer then! xD
Nah. Anything with screen on is far from 'light activity'. Screen consumes far & away the most juice. In saying that, I've seen some people on here say they can get 8-9 hrs screen on with 2000mAh battery. How they do it I have absolutely no idea.
But if yeah, 5 hrs with the screen on most of the time whether browsing or playing games (games in particular are very CPU/GPU intensive & thus use a lot of zzzzs; unless they're really basic games like chess or similar), or anything else isn't too bad. Can you do better ? Obviously, if people say they can get 8-9 hrs. But it's not a matter of doing A, B & C and you'll magically end up with massive screen on times. Every phone is setup & used differently, and getting the absolute max out of every charge takes a lot of trial & error and experimenting with settings/setup.
There are tons of threads about the subject on here if you feel like going down that path. For me, I'm happy with the battery life I get these days because you can really obsess over it & spend a lot of time stressing over it/trying to maximise it for often very little gain. I'd rather simply use my phone a lot during the day & charge it at night.
Yeah Crackberries are like Japanese cars, they can run on fumes pretty much ;-) Having a dual core processor, a decent GPU & a huge screen kinda changes things.
There is one thing you can do fairly easily tho. And that's to make sure the phone spends as much time as possible in deep sleep when you're not using it. That will ensure that you have enough juice to get you by when you do want to use it. Simple ways to help achieve that is to turn off data/WiFi completely when you're not using it (tho many people don't like to do this for different reasons; which is perfectly OK if you're happy to live with the resultant drain), and make sure you've got no apps that are doing things they shouldn't be doing (like syncing, for example) while the phone should be sleeping. Again, there are lots of threads about same if you ever feel like a bit of light reading ;-)
So yeah, if you do find you experience drain that's not normal/outside the usual pattern you have, definitely post details & people can have a look for you. And as you said, you'll get to know what really is normal with regard to drain & so on is as you use the phone more (I tended to use it constantly for that first couple of weeks as well).

Already took such measures. Wakelocks killed my battery over my first night with the phone, and I woke up after 7 hours to find a ~50% battery completely empty. Now things are alright, I clear CPUSpy stats before I sleep and wake up to around 95% of deep sleep time. Overnight drain varies between 5 and 10%.
And yes, yes you are right. Maybe I should stop going nuts. I'm checking BBS and CPUSpy every hour, reading every XDA thread on battery, and calculating my battery drainage every morning I wake up :laugh::laugh::laugh:

Umm...so I just woke up, and noticed a wakelock in the kernel category. It was PowerManagerService, and it occupied around half an hour. Overnight, aftet I've slept 10 hours (got a day off ), my battery came from 24% down to 13%. That's a rate of roughly 1% per hour. Is that normal? And also, what is that PowetManagerService wakelock?

Hi everyone. I hope this is the right forums for this thread.
I noticed a decrease my the uptime of my phone over the past few months - which is due to the age of the battery I guess, no nothing alarming.
But a few days ago, I flashed a custom rom (I was on Supernexus 2.0 - http://forum.xda-developers.com/showthread.php?t=2076650) Slimbean build 8 (http://forum.xda-developers.com/showthread.php?t=2060541) and all of a sudden my battery went haywire.
The phone would heat up for no reason (as if on charge + everything toggled on + playing a game and microwaving it at the same time) and I lost 40-50% over 20ish minutes.
I reflashed it with the same rom and the problem stayed though it was less frequent. Still I barely manage 4 hours without a charge (lasted at least 20 before that flash)
I went back to Supernexus (v3.0 http://forum.xda-developers.com/showthread.php?t=2407449). Battery life seems to have improved at bit and phone heats up less.
However on using the phone moderately - some internet browsing over wifi - I lost about 30% over 30 minutes which is at least twice as much as what I was experiencing.
On checking battery usage I noticed "Android OS" was coming on top (same as with previous rom) as opposed to the screen which was eating up most of my battery before.
I checked BBS but saw nothing out of the ordinary but maybe I can't read it properly since I'm not used to it.
So I don't know what to do now. Help anyone?
Edit: Added BBS log
Try a new battery (Go with the obvious stuff first).

I didn't see your message. I have no access to another battery unless buying one of course - which I'd rather avoid doing if it's not the problem.
I don't see this BBS log corresponding in any way with what you said in your first post.
From the log one can see that your battery dropped by about 70% within about 10h, i.e. 3.5% / 30min and not 30% / 30min as you said.
With a screen-on time of 1h 28m within those 10h 18m total time, the values are not really that bad I think.
To further improve the situation you should take care of the first wakelock (NetworkLocationLocator). Without this service waking up your phone permanently it will remain an additional 35m in deep sleep, consuming very little battery. Use google or search on XDA for what you have to disable to get rid of this wakelock.

Well when I went to bed it was at 100% charge. 87% on waking up (~8.30). I checked my mails, and browsed the net a bit (~9.00) it was at 56%
I fiddled around in google services. I didn't check it after flashing. Some stuff were checked by default. Will see how goes.

I've been running into similar issues, and doing a battery calibration seems to have helped me (so far). My phone would use battery quickly and also shut off without warning. I have used the option to "Reset Fuel-Gage Chip" in STweaks when running Siyah Kernel, but since I'm using SuperNexus 3.0 (not sure if I can use Siyah Kernel with it), I downloaded an app off the play store last night simply called "Battery Calibration". I'm still letting the battery drain completely so I'm not sure how well it works yet. Apparently it just deletes the batterystats.bin file.
After running the Fuel-Gage reset on my previous ROM, my phone no longer shuts off without warning. It would start to flicker the screen, kill the data, and then shut off with plenty of battery left according to the OS.
Doing this may hopefully help you as well, since you've been switching ROM's.
I have an LG G6 and a V30 on the Verizon network. On both, phone idle is using most of the battery. I've read several posts and searched the net without finding a solution.
I use a Samsung Gear S3 watch. Not sure if that could be the culprit.
When I Googled it, seemed like many others were also experiencing this problem. No one on this board is having this issue? Or has everyone figured out a solution? Thanks..
Why do you feel it is a problem? It doesn't matter unless your total battery life is not good to excellent.
Sounds like you just leave your phone Idle more than anything. I don't see a problem.
Sent from my LG-H932 using XDA Labs
check the battery usage ... find the offending app.
I am seeing the same: I don't use my phone very much, and not for gaming or video or anything very power consuming. So idle is by far the biggest battery drain on my V30 as well. The battery is still great on this phone, and it is quite frugal during use (as opposed to my beloved old Nexus 5, which was frugal when idle, but every touch of the screen would deplete the battery): I only charge the V30 every other night, and usually get 4-5 hours SOT on a full charge.
Battery stats attached. I have disabled most Google features (location reporting, always listen etc) but as you can see, Android Kernel and Android System remain by far the biggest app suckers. Lots of LG services buried in those. Some day I'll try and figure out which ones are the main culprits.

Either this is a bug from software or this is the way the phone display itself..
As long as it doesn't effect the battery usage, it's not a problem imo
The high idle drain is real, at least on my phone. It is NOT merely an error in how usage is displayed. If I left my phone completely unused, it would run the battery down in about 3 days, with no SOT. Significantly faster if I move it (say, in the car), slower if it's just lying on a desk. But even lying on a desk, it drains pretty fast. Even overnight, when AOD is turned off.
This is fact, not opinion. Of course it could be unique to my phone and the OP's, although a few other threads mention high idle drain as well.
As I wrote in my last post, the phone has a good battery AND a frugal display, which means it's not a problem for most. Indeed, owners who use their phones all the time will appreciate how frugal it is in active use -- although they too would get even more SOT if their idle drain was lower. Obviously it is a bigger problem for owners who use their phones less, and who want to charge it only every two or three days to preserve battery health.
I remain convinced that the drain is caused by some of the LG or T-Mobile services on my phone, which would cause it to be buried under System or Kernel usage in GSAM. I just haven't had time to dig deeper into which ones it may be. If others have suggestions for which apps or services are the culprits, I'll be very interested.
@mankind_18: I am glad to hear that this is not a problem for you.

This is fact, not opinion. Of course it could be unique to my phone and the OP's, although a few other threads mention high idle drain as well.
As I wrote in my last post, the phone has a good battery AND a frugal display, which means it's not a problem for most. Indeed, owners who use their phones all the time will appreciate how frugal it is in active use -- although they too would get even more SOT if their idle drain was lower. Obviously it is a bigger problem for owners who use their phones less, and who want to charge it only every two or three days to preserve battery health.
I remain convinced that the drain is caused by some of the LG or T-Mobile services on my phone, which would cause it to be buried under System or Kernel usage in GSAM. I just haven't had time to dig deeper into which ones it may be. If others have suggestions for which apps or services are the culprits, I'll be very interested.
@mankind_18: I am glad to hear that this is not a problem for you.

I'm actually seeing the opposite on my phone. Idle battery drain is minimal, but I feel like it drains a bit faster than others while in use. I did disable a lot of carrier/LG bloat I'm sure it's helped with idle battery usage to a degree.

Thank you for sharing this. Good to hear that your idle drain is low after disabling LG/carrier bloat. Makes me hope that if I take the time to go through it on mine, I may see improvement. So far I uninstalled a couple of LG apps through the Settings/Apps menu, that's all. I've meant to do more with ADB, just haven't had the time yet. Your post is encouraging in this regard.
But puzzling that you find active drain so high. My old Nexus 5 was like you describe: Very low idle drain (lean custom ROM and not many Google apps installed), but drained fast whenever I used it. As described, the V30 surprised me by doing the opposite. Hmmm....

Well it's not excessive relative to other phones I've used, just seems higher than other people based on their battery usage screens posted.

I think it's kind a normal to find idle taking up most battery if you're not using the device (i mean less), because when i compare it to a9 pro, it's the same actually.. when i use it often, screen will take the most battery percentage.. but if i use it less, device idle will be the most at the top..

If the phone is flat in 3 days, then your idle drain rate is 1.25%/h. That's elevated.
It should be possible to improve depending on what the causes are. Could be apps, could be apps you need and then there is the network.
As a simple test, charge up your phone before you go to bed. Then leave it there, untouched with AOD off.
In the morning, settings - battery - battery usage - estimated time remaining <-- how much is that ?
Your battery will have to drop to at least 98% before that info is available which in your case could be sooner than morning maybe in a couple of hours

True. After two days you've lost half the battery. Ideally it should be less than that.

Thank you for the response. That was posted over a month ago, and I finally did get around to disabling (or rather, uninstalling with ADB) a bunch of LG apps and services. Also some T-Mobile apps after switching to AT&T MVNO. That helped a lot, and I am now down to approx 0.5%/hour idle drain. That's overnight, mind you, and I still find it somewhat high considering AOD, Location, Bluetooth, NFC are all off, and the phone is completely still for 8-9 hours.
But I can now generally recharge only every three days, and still get 6-7 hours SOT. I guess that is great for any phone. Sometimes and I have to use Battery Saver to make it that far. It helps a lot to reduce battery drain, both during idle and use, and has no noticeable effect on usability.
Also on the positive side, I haven't had any of the lag issues mentioned by others in various threads after disabling apps. In fact, it is even smoother than before disabling them. I did go a bit too far, as I lost the ability to Google Cast the screen -- strangely, as I didn't touch Google apps or services. Also, I lost LG SmartSettings, which I didn't actually use, but didn't mean to lose either. I kept the SmartSetting app, but apparently one of the LG task related apps I disabled caused it to disappear from Settings. No other issues or functionality losses -- except the ones I wanted to lose.
So I am OK now -- though I still think idle drain is higher on this phone than it should be, even after disabling LG's duplicate and redundant services and turning off known battery draining features (AOD, Location etc).
Edit: Thanks again for your response and offer to help. Re-reading my post, I don't think I fully acknowledged that.

By adb i was referring to granting a one time permission to the better battery stats app. Will be a good next step if you've not used it yet since you've done a cleanup already.
The dump file will reveal what your phone is up to when you set it down and whether further improvements can be had if feasible.

How did you measure that rate ? wonder if its possible to reduce it further. Up to you

6-7h/SOT is normal for the v30, on wifi or bands 12 & 20 with heavy use.

If you're interested in exploring further with BBS, let me know. It has a strict procedure to follow which i can walk you through

I did grant usage stats permission to GSAM. Otherwise it wouldn't have shown the details in those screenshots.

GSAM can show stats for various time periods, including custom ones. I generally check it in the morning after it's been lying on my desk or nightstand overnight for 8-9 hours. That's the ultimate Deep Sleep condition.
MY cell radio uses a bit more after switching to AT&T and returning the signal booster that T-Mobile provided me. The booster didn't improve T-Mo weak's reception in my apartment, but it DID provide a stronger signal to the phone, so it doesn't have to work so hard to maintain it.

I'll take you up on that. I haven't used BBS in years (different phone) so not up-to-date on it at all. I'll follow your procedure, just tell me what to do.
Thanks again. Much appreciate your help!
Edit: I downloaded and installed BBS 2.2.2.0. Holy crab, I can't believe that thread is now 3300+ pages!

Good, this will allow you to compare both tools and see which one is more useful.
Now you need to give BBS the permission in ADB as shown here
adb shell
pm grant com.asksven.betterbatterystats_xdaedition android.permission.BATTERY_STATS/
That's it. Switch off Developer options.
Then go into BBS-Settings-Advanced- (scroll to the bottom and click System App) and verify it says BATTERY_STATS granted. Cannot proceed further otherwise.
If ok, back out of advanced and tap 'Watchdog' then enable
Next, try a dry run. AOD off. Let the cell be on since that's how you use it and wifi.
What battery level is when you start the idle test matters. Can be anywhere between 50 to 95 but not over or under. More consistent data between those two points.
Let it rest for an hour. Do not touch it during this time. if the phone rings and you answer it then your log is going to get polluted with irrelevant info. It's useless, have to redo the idle test. The not touching it matters a lot.
When time is up, in the app under summary there are a couple of dropdown menus. Select 'Screen Off' instead of 'Boot' for the left and the menu next to it, select 'Screen On' instead of Current. Telling it to print data only during the time screen last switched off and turned back on. Very handy. As you can use your phone before the test and when ready to do the test it doesn't matter where you start within the limits mentioned. Screen off to screen on, That's what watchdog does.
After that, Look for the share button at top and select Dumpfile then Save. The txt file will be saved in emulated/0 so in LG's file manager, Internal storage, scroll down, it should be there by default. file name betterbatterystats- date-time.txt
Post that txt file as an attachment in your next post. Hopefully, on the V30, BBS will record under the sections, partial wakelocks, alarms, network which are required to understand where wakes are coming from. If this part is successful then you can go on to do a real idle test.
There are three key points here,
- idle test done when battery between 50 - 95
- your screen on during the idle test cannot exceed 1 minute. No touching
- getting the correct start and end points meaning you selected screen off to screen on to record in the dump.
Get this down right and you will be ready to do a real idle, test. There is one extra condition now. Test cannot be less than six hours. Can certainly be longer but not less than 6h. This is where the no touch rule starts to grate but that is the minimum time required for any wake locks to make themselves known. Getting the procedure right means you don't waste runs. And you will be doing several as you hone things
A bit rigourous but this is what the creator of BBS and the guys in that 3k+ thread insist you do to get the most out of BBS. They won't look at your dump file otherwise. Redo it they will say

Thank you. I'd already granted it permissions (BATTERY_STATS and DUMP). But I cannot install it as System app, since I am not rooted -- which it promptly tells me if I try. I was looking for somewhere to confirm the permission, but didn't find it.
Anyways, I started the Watchdog. I'll be charging it overnight, then do the dry run tomorrow after the battery has dropped below 95%.
Thanks again. This will be interesting!

Ah, i wasn't clear, install as a system app isn't required, that screen is just to check if the permissions took.
A popup appears saying root is required and disappears after a second or two, if you see the word 'granted' then you're good to go. Fingers crossed the right sections get data
