So, this post is 1/2 "rant" and 1/2 "any ideas", but the JI6 Update has been (in my opinion) a very serious letdown.
First of all, I can't be alone in thinking that the late-September update from Samsung would be a full-blown upgrade to Froyo. Obviously it's not. I guess we'll wait awhile before that's released
Secondly, I'm one of those sorry saps that had the update soft-brick my phone. It took me a few days to get around to the ODIN fix (bumping me back to "stock"), but it was still a royal pain.
Thirdly, I've already seen some issues that I didn't have before. For instance, the phone "froze" on me while sitting at home: no screen response. I had to pull the battery and power up again. Nice!
Finally, the battery life is utterly horrible for me -- and I'm not sure why. Currently at 26% battery life (now 8h 4m since unplugged). 34% of the usage is "display", which has been on for 28m total. 22% is cell standby. 15% is phone idle. 10% is voice calls (2m 10s of that). 8% is the Android System. So on and so forth. Basically, I've *hardly* used my phone today, yet the battery isn't going to last thru to the afternoon. I have 6 active applications, with none of them hitting the CPU at all currently. Best of all? The battery icon looks like I'm about 1/2 full, so evidently Samsung couldn't be bothered to make that icon accurate. I know about the battery icon mods out there (I've used 'em), but I figured Samsung would take care of that.
Sorry for the venting, folks. Is anyone else seeing similar stuff? Any ideas on the lame battery life??
Thanks,
Yip
For me Android 2.1 which samsung released in Galaxy S is exactly like Windows Vista ! No matter how many updates you release for it still will make your phone **** !
The only option is to release a full new OS which is Windows 7 = Froyo !
Better than Windows NT = 1.6
Getting your phone bricked isnt the updates fault, there are hundreds of threads out there and reading just one couldve given you signs of warning.
As for your battery life, I am willing to bet your phone screen is full of widgets. Try limiting those, as well as automated syncing. I get excellent battery life that can EASILY last me the whole day (I actually find myself running avatar/pandora at the end of the night just to drain it so I can recharge the battery).
However, I do agree that the inaccurate battery reading should have been fixed a long time ago (or at least in this update) and that froyo should have been included with the release of this phone.
Your cell standy is too high which means you have things constantly using the cell signal to pull data, thus draining your battery. Right now I'm at 72% with 67% display, 14% voice calls, and 9% cell standby. Been unplugged for 3 and a half hours.
Not great but I'm purposely trying to let it die because I'm reconditioning.

Ha! You may just be right on that. Eclair seems like a fairly lame version of Android, if you ask me. Not horrible, but not great.

"Signs of warning" means nothing, my friend. There are folks who didn't even *root* that got soft-bricked with this update. It was (somehow) poorly handled.
As for your widgets comment, well... you would've lost the bet. I use a single screen, no widgets, no weather stuff, bluetooth off, wifi on (but currently turned off), and nothing extraneous. I run Android about as light & frothy as you can get! I prefer speed over just about everything.
Any other thoughts, though? Perhaps I should re-load Autostarts to see if there's anything strange launching at boot time...

Interesting. Any ideas what would be pinging the cell standby so much? I'm in a high-bandwidth area (full bars), so it's not like the phone is struggling to get signal. I use Gmail and Exchange, but my Exchange sync is set to "hourly", rather than push.
Doesn't seem like I'd need to disable my 3G connectivity. I certainly have never had to before.
You should probably reflash the update. JI6 was great on my phone, no hiccups, no lag, perfect GPS.
Also, you should recalibrate your battery after the update and give it a few days to settle down. I always get horrible battery life after flashing a rom, but after a few cycles I'm back up to 24h+.

Honestly, I wouldn't know unless I knew your full setup. What I will say is that I do have a lot of widgets and apps running that pull from the internet but yet my cell standby isn't as high as yours. I haven't reduced any of my sync intervals either. The 3G radio can really drain battery fast, faster than even the screen so that is a problem.
Also, in JI6, they increased the strength of the radio so it drains even more battery. I am running the JI6 modem however.
You should use something like WatchDog to see what is constantly running and using CPU. That could give you an indicator of problem apps.
Well, I'm disabling some startup items: Visual Voicemail, Telenav, and Daily Briefing -- none of which I use. Maybe that'll help. I don't know...
I was really trying to run "stock" this time around -- not so much fooling and tinkering with things, but it doesn't appear to be paying off for me. Frustrating.

Oh wow, yea definitely you need to disable all of those. That's the first thing I do. I actually uninstall Visual Voicemail, Telenav, Amazon MP3 etc. ALL of those things constantly run for some reason even without you opening them once.
You're not alone. My battery life is terrible as well after the update. I'm losing 4% an hour on standby.
That said, my phone is smooth and working great when I do use it.

Again, if you didn't do so after the update, wipe battery stats and then do a few full drain/charge cycles. My battery life always sucks after flashing a new ROM, but it always goes back to normal given time.

after the update for me, my gps is much better, but i actually have more lag then i had stock before....
so I need to either flash a kernel, lag fix, or a rom with at least one of those.... its kind of frustrating to have lag just from opening or closing a simple app, messages, or call... I honestly cant believe a phone with these hardware specs can have lag just from somthing as simple going into the dialer and exiting out...
Battery life seems to have decreased a little but still getting a good 20+ hours. GPS is a little better with use wireless networks. Lag is an issue now though. Didn't have much before a the update. Hopefully its solved in another update or froyo.

So I applied the update on Tuesday through Mini Kies. First experience with this update, it's been great. My phone seems to faster, really I hardly experience any kind of lag or slowdown (and this is in comparison with my stock vibrant running OCLF). Battery life even seems to be better, but that is probably to do with conditioning. So everything has been good except for the fact that my phone has froze on me TWICE today. I'm thinking it's something to do with the apps though. I was in Layar and it was working for a bit when suddenly, it froze, I didn't have to pull the battery I just held the power button down for a good 5-10 seconds and it restarted. The other time was in a game, which kind of concerns me. I suppose I can reinstall both and see how that goes. I'm thinking it has more to do with the apps possibly being corrupted. The first thing I did was install the 2.2 market on my phone and I ran the update all function on like 15 apps that needed updating. Not a good idea imo, the market went crazy and forced closed a couple of times. I'm not entirely sure what is going but it seems like my phone is only freezing in certain apps. I hope it's not just some random freeze that can happen at anytime, that wouldn't be no good.
You guys complaining about battery life... i would Love to have your times. I got 3 hours and 8 minutes today on a fully charged battery.
I wouldn't even say I use my phone frequently. When I used the miui or however it's spelt rom I would have 60 percent to 30 remaining each day. On gingerbread? I'm down to 15 percent every day and every night my phone has shut off due to lack of battery.
Isn't there any rom with excellent battery life? That's all I want, I use my phone for tethering.
i put CM7-RC2 on my device yesterday and it's the best battery life i've ever gotten.
Gb battery life owns, u got something else going on
No he doesn't, i've measured religiously since the original nexus shipments and this is by far the worst
My battery was really bad but now it seems to last me 10hrs & up which is weird for a phone to last me that long. I really think theirs an app or bug running the battery crazy I don't use any task managers. Their was a thread somewhere saying to run your phone on recovery mode and to press on the reboot/restart and battery get better I did that so maybe it does work but I highly doubt it.
I can vouch for poor battery too. I am on CM7 RC2 and I can't even make it through a day with light use. By light use, I mean practally not using the phone at all.
My battery life seems to be better than ever. Some 10-20 percentage units more left in the evenings all down the line.
Edit: Stock GB, no task managers.

I agree. Gingerbread has been nothing short of AMAZING for my battery life. The battery life is so good now that I stopped using my spare battery altogether!

Did you happen to do an Update or a full install when you got gingerbread?
Some suggest that it's due to the update process.. so you might want to try a full install:

Remember to wipe your cache first..
What i noticed is taht custom roms use more battery than stock rom. this is for me i don't say that it is like this for everyone. But with gigerbread i got the best battery life. i also think using apps from SD uses also a lot of battery life, but again i have no other choice to low on memory.
bug
I had the same problem. I am on stock gb.
Just set wifi sleep policy to never. It will last 2 days after that. It is definetly a bug.
Seems to be a real mixed bag with GB on N1's. Lots of people saying "better battery" many others, myself included, reporting much worse. For me, I experienced very poor battery life right from updating to the stock GB using the singned passion .zip file. Even did a factory reset, and only reinstalled my daily used apps and it made little difference, then I went back onto a MIUI rom for a few days and battery life was wonderful again.
Then early this week I flashed to CM7 RC2, and for two days battery life was the worst I've ever had.
Had been seeing a few comments on different forums of people who had the same problem swearing black and blue that after they changed the wifi sleep policy to "always on" their battery life improved dramatically on Gingerbread.
I know if sounds backwards, and that is why I was sceptical for ages, but last night I made the change to see if it would make a difference for me today and all I can say is WOW!!! Phone had a real test today as I started work really early. As of right now the phone has been off charge for 16 hours.
Half a dozen or more voice calls, minimal text, my usual wifi and 3g data, about 10 min of streaming video over wifi and about 1/2 hour in total running Navigation.
There is no way in hell my phone would have done all that and even lasted me 8 hours prior to changing the wifi sleep policy - so I think there is definitely something in it.
As for the ppl who aren't noticing bad battery, maybe they already had theirs set this way - or maybe it's an issue only effecting certain batches of devices (like the wifi reconnect issue which seemed to be pretty common pre froyo)
it /WAS/ terrible at first. Really, really dire, but it's back to what it used to be, even better now perhaps.
To the OP, do you have WIFI turned on still? I used to leave it turned on and it didn't ever knock down battery as it was going to sleep and not coming back, so wasn't a drain. GB appears to have fixed this, and it was staying on, thrashing the battery.
Turning it off and turning it on as needed only, battery life is now fine.
Do you have WIFI Turned on? Bluetooth? For now, to try and test what's happening, turn off 3g, wifi, bluetooth, automatic date/time sync, and JUST use it as a phone for a day. See what % you're at at the end of the day.
Then we can take it from there.
But I'd be pretty certain that it's wifi related, in that it's now working as it should be, we just got used to it being broken before.
My phone on cm7 rc2 has worse battery than I used to have with wildmonks kernel and cm6.1. Yesterday, the phone was barely used until 8 o'clock at night. It was at 45 percent. After an hour medium use, its gotten down to 23 so I had to plug in the phone....the easiest fix? Keep a charger In the car!

Using stock Gingerbread and I can say that my battery life is decent, better than Froyo for sure. The phone lasts longer than 16 hours and I use bluetooth to listen to music for 1.5 hrs on my commute home. By the time I get home after a long day (8pm'ish), I still have about 20 to 30% left.
I have no wifi no bluetooth no gps and a dim screen.
Tis is seriously crappy battery life.
Does anyone think they can link me to a good miui rom. For me, it seems that gb just wont work.
I am running stock gb then i flashed the root and my boot loader is unlocked.

Listen to this person!
For some reason, since 2.3.3, if you have your Wifi policy to sleep when the screen is off, Android will rip through your battery. You'll notice Android OS taking all the battery on the status page.
Set the sleep policy to never and you get better battery life again. Turn off Wifi manually when you're not using it, even better. Until somebody fixes this bug, I guess it's the only workaround we've got.
More info: check issue 15057 on code.google.com - cant post link due to the newness of this account.
Same here on shorter battery life my nexus one as well post gingerbread ota... I will look into detailed system processes and try to find out why...

Log into latitude and log out. Every time there is a map update it defaults to being a battery draining monster. But in essence. Something to do with maps link to latitude (which i don't even use) breaks my phones battery life.
Hi guys i know there are lots of similar posts about battery life etc but cant find the answer im looking for after a search of this forum as all answers seem to be on rooted devices, she does not want her x8 rooted and im really getting it in the neck for upgrading her in the first place lol.
My girlfriend recently got the 2.1-update 1 via pc companion and thats when the battery problems started. The battery drain problem has actually been getting progressively worse since this. This morning (after yet another full night charging 100%) after 30 mins of getting up today the battery was down to 83 %. I have already uninstalled maps updates, not that she ever used it anyway.
So my question is : is there a solution to this without rooting and/or having a custom ROM? becuase she making my life a misery lol.
Thanks in advance guys and sorry for the similar post

Well, 1st thing as Dx said. reboot after using wifi, 3g, music. reboot to make everything fresh.. but there's no other way to save battery without rooting I think. because I helped my gf installed a custom ROM for her and she said that the battery life changed, and it's way different than a original ROM. How come she doesn't wanna go custom? Sorry for my bad english.

Agree with you!
Nah, rooting makes the difference. IMO Froyo ROMs have good battery life.
Well i think she might well have to go custom because the battery life is a joke now, nearly rendering her device unusable, think she just frightened cos i did her pc companion update and kinda blames me for the crap battery now, il have a read around the x8 forum on how to root.
Thanks everyone, apreciate it
Just try to keep off all things you don't need: Wifi, Bluetooth, Synchronization, 3G. also unninstall apps you don't need and do not use app killers to save RAM.
I think that is all you can do without rooting.

My friend, less RAM is actually a good thing. I've read through the web. just don't auto kill ALL the apps, kill those apps that when it doesn't look right or freezes. The more RAM you freed, the more battery it will drain. Serious.

I'm just a noob trying to help.
use a task killer and disable all what you don't need like bluetooth, data traffic, gps and wifi. yes i know my english is bad^^
disable wifi, gps, bluetooth and data traffic. stock 2.1update rom should get you about 3 days with those disabled. any apps that need them will ask you to switch them on again anyway. It's a little annoying to get used to at first especially when you're used to a fone that lasts a week without charge so I can understand how she feels especially if she only wants to text and do a few calls.
If you don't use wifi, 3g gps and rest of the s**t you should probbably buy a dumy phone.
With some "normal" usage you can be happy if it lasts for a day/day and a half.
2-3 is really success.
You do get a charger in the box with the phone you know?
Use your phone, stop wasting time on battery monitoring.

yeah but the idea is it's a MOBILE fone.. You dont want it plugged into the damn socket all the time!
If you need to use the GPS, WIFI etc. the app will ask you to switch it on so wheres the harm in turning it all off until it's required if it saves having to plug the thing in every day?!?
Nobody stated you should keep all the functions on.
But it should be understandable that, with some "normal" use, and by normal I mean regular texting, phonecalls, check facebook/twitter, refresh weather app, read mail and some news maybe you can't expect your battery to last 7 days like on dummy nokia.
Besides, you all forget that your biggest battery killer is the screen.
And another thing I noticed; when LED starts to glow green, your battery isn't fully charged. Check phone status. It becomes green after passing 90% I think, or so.
And the second thing I noticed is a HUGE differenc when charging the phone while it's on, for a hour and a half when the battery metter reaches 100% and when I turn it off and leave it charging over night.
The "night" option proved to be a lot better (battery lasts longer, doesn't fall so fast) + Every once in a while it is good to fully discharge the battery and then fully charge it.

Yeah, but that mobile phones have long since ceased to be just phones.
Switch off everything you can : wifi, brighteness, gps etc. Also you can make a profile "screen off " in setcpu and set it to 122mhz . it will save you a lot of battery! It drains just 1% after 5 hours ( but i didnt use my phone) . Hope it help.
Oh yeah and use the app called " fast reboot " it is so good is well and it speed up our lovely x8
When i used these things , my phone lasts in a week or more of.course i nearly didnt use my phone.

Seeing as I don't have enough posts to post over in the development forum, I thought I'd hijack this thread.
I installed this rom last week and at first, the batter was brilliant. It lasted for three days but now I have to charge it twice a day. I have bluetooth off, wifi off more often than not, brightness down very low.
The phone was 5hrs on battery and was down to 44%.
Cell Standby: 35%
Display: 20%
Phone Idle: 19%
Launcher Pro: 13%
Anyone have any ideas?

Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?
There has to be something running in the back ground draining battery. If not try finding a battery Conditioning Application

Based on the above it could be a few things.
If you want to check a few things on the phone side you can:
- install GSAM Battery and let it keep an eye on what's actually using your juice. Then either remove, modify, adjust settings, etc, for whatever is using it. If it's an app... delete it. Reinstall it.
- You can try a factory reset
If neither fix it then you can try another ROM, but if your battery is just as bad with a factory reset I'd lean towards the battery. Maybe you have some bad cells.
I've had mine for a bit, and I only lose a little bit if not touched overnight.
My current setup:
- Madhi 4.4 KK ROM (1/18 build)
- Obviously rooted with the above
- Greenify on all my non-necessary apps (hangouts, weather and one other app spared from this)
- All my apps auto-sync features are disabled since I just run it once in a while, and things like mail / etc I don't need push anyways
I get pretty solid life even after a few moths of use now.

first, install betterbatterystats and look for wakelocks, try reseting the device. batterylife also depends on how you use the phone...i can get 9hrs on screen time reading books with still 15% left or drain it in 3-4hrs playing games.

Yes i have downloaded and used gsam battery app. I dont see anything unusual in my stats, also using better battery stats, its been in deep sleep for most of the time, and it doesnt say the phone was on or running when the screen was off. But for some reason i wake up and my battery is decreased by 50% again....I am using greenify and hibernating alot of those annoying apps. I am stopping apps that are running . And on the phones battery manager android system is first with 34% but it says its only been running 11min, and no gps is listed. And my screen on time was 2 hours those are what i foudn when i woke up with 20% left, at night it was 70%. I seriously think my phone is messed up when im using it its not that bad, but for some reason when i go to sleep and leave it alone it dies for no reason....

When i woke up my battery went form 70 to 20%.....i am using greenify, and stopping running processes, like carrier iq an other apps. i dont know whats wrong...this is getting frustrating, i have also factory my phone already, it was fine for a few days but now its constantly draining like crazy at night...i love this phone, but i think mine might be messed up! You think changing the rom would make it go back to normal? Even though my phone isnt supposed to be behaving like this with stock...

I definetly would try it. Also you could try different kernel. But its beginning to sound like there could be a defect in your battery. If nothing helps i would send the phone to LG and let the battery replace. You are still in warranty, right?

What exactly is a different kernel? And well i got it through craigslist, im not the original owner. you think they would still give me a warranty?

Has anyone been experiencing bad battery life on the g2? When i first got it a month ago it was amazing easily getting 50+ hours with about 6 hours screen time. But over time its been getting worse. I already did the whole stopping the carrier iq and all that, it still doesnt help much. Now when i go to sleep and wake up 7-8 hours later my battery drains 50% or something like that for no reason, no wifi or anything on or synced. I did see some posts about people experiencing bad battery, this phone is supposed to have amazing battery life whats going on? I rooted my phone, still on stock rom, wondering if anyone has fixed their battery issue. Would installing a new rom like aeon v3 help improve battery like its supposed to be? Its getting frustrating, my gs4 had worse battery but at least the standby times werent as bad as they are on my g2. Any fixes for this?

my battery has a problem too..
when my phone is idle sometimes the battery level increases by 1 or 2.
when im playing heavy games like gangstar 4 the battery decreases every 2 mins and the temperature reaches 40°C. and when im just browsing it decreases every 3-5 mins with a temperature of 34-36°C. and when im watching kuroko no basket (wifi off) every episode just consume 2-3% of the battery (24 mins. = 2-3%)
and the temperature is about 28-30°C.
I think my battery drain problem depends on the temperature
HELP!!!
I picked up an H918 for my wife to use on T-mobile USA. Since it was used, I also got one of the extended life 4100Mah batteries to hopefully make it last at least the entire day without topping off the charge. She usually averages around 4 - 5 hour SOT, so this seemed like a good option from what I've read, and fits in the original door so I can use the wallet case she wants with it.
But man, her battery life is TERRIBLE! I checked with Accubattery, and it reports that the battery is charging within 99% of it's 4100mah spec, so I don't think its a bad battery. Yet, she can barely go 12 hours with just under 2 hours SOT before the phone dies!
She is unrooted, running stock Oreo.
I installed GSam Battery Monitor and used their ADB commands to give it permission to record deep statistics w/out root (pretty cool, never did that before). I ran it for a little while this morning. Within 3 hours 40 minutes off the charger, she was already down to 72% with barely any SOT. I'm attaching screenshots of the app usage and doze screen (sorry for the phone-snapped-of-phone picture, it's my wifes phone like I said, so it was easier to just snap with my camera than take a screenshot and send it to myself to post).
Maybe I'm not reading this right, but it seems like something is keeping her phone from sleeping. A big culprit seems to be call services, and in my location settings, I noticed it mention that LG IMS was doing a lot of heavy battery drain with location related inquiries.
I thought maybe it was related to WiFi calling, so I turned that off. Cell reception is average.
2 hours later, she's down to 50% so that wasn't it. I don't know what else to try other than hard reset, but we literally just got this and set it up 2 days ago, and its been like this from day one. I don't see why it would be any different the second time around.
It's likely a junk battery. It's really hard to get a good oem replacement battery.
If you shop Amazon look for a Taeozi 4200 or Shemnz 4200. They both have 2 year warranty and decent reviews here on XDA
The Perfine 4100 is also highly recommend
Any Li-polymer should be better

When I bought my wife's phone it had a battery drain/overheat and wakelock issue as well. I fixed it and haven't had an issue since. Here's what I did to fix it:

I did my homework first and got the Perfine from Amazon, not a no-name junk battery. When I couldn't fit it without removing the sticker, the seller was really helpful and actually offered to replace it after checking first that it fit in *THEIR* V20 at the factory. Really solid customer support. And according to Accubattery, it really is the capacity it says. Or at least within 99% of it (I think it estimated 4080 or something like that). So I don't think that's the issue.

That's actually really interesting- I did take apart the phone to do the thermal mod thing (wiped off the dried up pink gunk and put a thermal pad there), but it seemed pretty clean otherwise inside when I did. How on earth did you figure out that was the problem?
After speaking with some folks on Telegram, Reddit, and other corners of the internet, I have a different theory. A bunch of people told me to let the rom "settle", that battery life is never good after a fresh format or new rom flash. Honestly, the critical thinker in me says that sounds like nonsense. I've never heard of this before and I've been flashing roms for the better half of a decade. I'd think after it takes the time the load up your apps and settings and configure itself, it would be done. But I Googled it, and it seems to be a hotly debated subject.
Those that swear by it claim that whenever you start fresh or flash a new rom, it takes anywhere from one to a few battery cycles before the kernel calms down. Perhaps it is doing some sort of internal calibration based on your battery life and system demands or something like that. The theory seems to be that the Kernel doesn't allow the CPU to fully doze until it is done with this process, which sometimes takes days. I don't know, but the more I read about it, the more it sort of started sound plausible. When I got the phone, I tried out some things on it myself without a SIM card first, just to make sure everything on it checked out before giving it to the wife. Then, I did a hard reset, popped in her SIM card and let it do its thing. That's when we realized battery life was pretty terrible, as after 10-12 hours she already needed to charge... and this was on the 4100mah perfine!
I tried another hard reset, and when that didn't fix it, I decided it was time to root and see if I could get to the bottom of the bad battery. It seemed the kernel was where a lot of it currently went according to battery stat apps. After downgrading my H918 to Nougat so I could install TWRP, I promptly flashed Alpha Omega Oreo 20H and restored her apps. Turns out the next morning we couldn't sync her smartwatch, somehow we broke bluetooth (going into BT settings would crash the phone everytime). So weird, and while we were at it the battery life still wasn't great. So I did a hard reset that evening and found that even with nothing installed, BT was borked. (looking back at it, I think I should have flashed an Oreo rom like the stock 20H rooted first, and THEN the AO rom. I think going straight from nougat might have led to a driver mismatch or something)
Anyway, after that didn't work I flashed the stock rooted 20H rom, and lo and behold bluetooth and everything else is working again! But the battery has been bad all along and is still doing its generally suckiness thing.
BUT... as someone pointed out, if this kernel settle thing is real, I've been pretty much flashing and resetting this thing every other day. If roms need to "settle" first (still a debatable subject), than I never really gave it a chance yet and that's why I'm constantly seeing battery drain from things like Kernel even on different roms! And @pistacios, is it possible that you were having a kernel do the same thing since it was just reset and it just so happened to be that when it calibrated itself you thought you had fixed it by cleaning out the USB port?
All I know is I'm going to give this a couple of days before deciding on a plan B. Seems too simple to be the reason, but hey- I'm desperate.

Ive experienced ROMs settling in and battery stabilizing after a few days. But this was pretty far back with the HTC M7 and M8. Most modern phone's I've flashed pretty well settled in within the first few hours. The battery life on this phone was never amazing. It was good to just Ok for most when it was new.
If you flashed the stock rooted rom and still had bad battery life, I still suspect the battery itself. I still recommend one of the battery I listed earlier. If the perfine didn't work out try a different one.

Right, with the stock 3200mah battery. With the Perfine 4100, a lot of reports are saying 6-7 hours SOT or at least a full day of regular use. That's good enough, really. Mine is dying at half of that. I'm wondering if I have faulty hardware. I could put the stock battery back in and see if it dies much sooner.
I'm actually wondering if someone can check their mA use per hour with the screen on vs off, and I can see if the numbers make sense on mine. Accubattery is pretty good at the math.

Phone was up and running for 2 weeks, so it wasn't due to fresh reset.
GSAM battery monitor showed kennel wakelock, something about USB OTG in the top of the list, so I figured the port was my first check for a problem, and it was. It wasn't obvious that there was dirt or foreign matter in there, because it looked clean. But sure enough, after the light brushing with 94% alcohol, the problem disappeared.
I'm not saying this is definitely your problem, just throwing it out there.
