So I get terrible battery life with .33.4 kernels (925 or 800) but got phenomenal battery on Ravens 800mv from 5/03. Are there any .33.3 kernels that will have the right drivers? How hard would it be to mod?
Thanks
Have you considered just sticking with the stock kernel? I'm getting phenomenal battery life with the stock Froyo kernel. Last I checked, i was at 46% after 28 hours unplugged (pretty heavy usage too - streaming music over 3G, several phone calls, tons of texting, youtube, web browsing)

My battery is getting raped on froyo almost to the point that I want to roll back to enoms 2.1

what do you do to get that much battery? my battery life isnt so good on froyo
I tried stock. Wasn't great but was better than avs.

all kernels are going to depend on how much you play with it, and what you have running. if you don't have a load of widgets, background data, bluetooth, etc running, you should get decent battery life.
the more crap you run, the more energy it takes. common sense.

This!
And I am getting pretty good battery life off the stock Froyo kernel. Actually, I am only draining at 2.2% an hour, and have had my screen on for 1hr 57 minutes, and the device off the charger for 14 hours. I have also made about 45 minutes of phone calls, and let it download with the screen off a bit.
Personally I have similar battery life to what I was getting on cm with uv/oc kernal. It does appear like it might be a little worse but I need time to be sure. Regardless I have gained small but real improvements with battery life on both cm and enom using the custom kernals and I have no reason to expect another result with froyo. Since battery life isnt exactly something I would describe as gratuitous on the N1 I will be kernaling up as soon as one looks like it actually works without issues. Right now thats not exactly the situation as I read down in development. There are a few usb mounting issues going one way and no cam going the other. Hopefully there will be a more hashed out kernal soon as the guys get more time to play with it. So getting back to the begining you ought to have something to work with shortly.
So no one will ever get the old kernels working with Froyo, huh?
If only I could find one that worked well without the USB dismount issue or the wifi issue, everything I've tried has failed. IMO 2.6.34 so far has worked best for me but has the dismount issue. I've tried four so far and none of them work well. I did get pretty proficient at moving zip files from dropbox to the sd card though.
Battery life seems to be so across the board dependent on so many variables that it sometimes seems like it's not even worth trying to gauge other people's experiences. I've tried numerous ROM/Kernal/Usage/Setting combinations and have never gotten what I'd consider to be 'good' battery life. 2.2's no exception.
I just ended up buying this 2 battery and external charger pack off of eBay for 20 bucks and admitting defeat. Our superphones are luck of the draw it seems when it comes to battery life. I'd follow someone's set up to the letter and get nowhere near the battery life they claim to get. I can turn off syncing, keep the screen dim, run a kernel that's supposed to get great battery life, and still get around 3%-5% drain per hour on standby.
My morning routine has me use bluetooth stereo headphones for about 25 minutes on the metro while I look at a couple of webpages. From out the door fully charged I'll be down to around 82% when I get into the office. To me, that's laughably terrible, but it's the only life I've ever known with my Nexus One.

It is terrible and I was in the same boat as you. I found the kernel from 4/29 800mv and 5/03 800mv to be the big winners for me. Any other kernels and my battery drops like dead weight.

Ya. The two kernels I mentioned are the ones that had me going 1.5-3 days depending on usage.
In right there with you guys. I unplugged at 8am and now its 10am and I'm at 78% this is how its always been.
I downloaded the 5/03 one and I'm trying that one out now, thanks. Maybe we'll see some improvement. It sucks to lose the ability to record video for a chance at battery life on par with what I'd get on a RAZR, but that's the world we live in.

True enough, but phones in the same category perform much better than ours in terms of battery life, and they never made the claim to be 'superphones'. And AMOLEDs are designed to not use a lot of juice, but HTC somehow botched that idea, from my research.

I agree... Hopefully the "final" release of Froyo will have an updated kernel addressing the battery life. To be, it's not a big deal because I am always near a charger but it would be nice to be able to get through an ENTIRE day of heavy usage without worrying about the battery dying.
I havent had a smartphone recently that could didn't need to be charged every night. I would love better battery life as I jmake it through weaker usage days at about 40% moderate usage at about 25% and with heavy use I have to find a way to get plugged in to get through. Still, reading how other similar phones (large screen 1 ghz etc) are doing leads me to believe that the N1 is roughly comparable. I'm not sure how you can compare a modern smartphone to a far less power hungry (and capable) feature phone that a person almost certainly did less with over the course of a day?
Ok so I read a post that said drain your battery completely for better performance so i did.Got low bat warning and played Avatar to kill it quick.Only it didnt die fast,seemed like forever for this damn thing to really die!!!Maybe I just imagined it so I tried it again.Got low bat warning and watched a 25 min youtube vid followed by a 16 min youtube vid and several rap videos before it cut off.Try it and see how long it takes to really run out of juice and I think youll be surprised
I remembered with my G1, that once i got the low battery warning, I was always able to milk every ounce of power from that battery.
after picking up my vibrant yesterday, i charged to a full 100% with the phone turned off
i've been on it all day long, installing apps and restarting quite frequently, and i just got my first battery warning (21%)
will probably run it into the ground after work for another full cycle charge then just charge whenever it needs it. seems to have more than enough to make through a full day, and i'm only saying this because i haven't been able to put it down since this morning and it's still ticking
edit: and this is all done indoors with fluctuating 3g/2g coverage (home and work)
I have twice run my battery into the ground and charged to 100% with the phone off. Now I am getting a little over 25 hours on a single charge. this battery is indeed better than they said it was.

Better than what?
If coming from an old WM, sure, it's better.
But coming from an iPhone, which lasted for 2 days with real use, the battery of the Vibrant sucks.
With moderate use, I can's get through a full day (14-16 hours). It's the one real problem I have with this otherwise great phone.

I had two 3Gs (now have a Galaxy S and a Vibrant). It lasted almost double what the Vibrant does, with similar use.
Love the screen of the Samsung, but the battery is making me a little depressed. I am hoping that Froyo will improve it a bit.

yeah, hopefully drops sometime soon.
it seems battery life is either really good or really poor, not a lot of middle ground. of course, this could mostly be because of different peoples' opinions. but i'm coming from a dumbphone i only had to charge once a week, and so far i'm pretty impressed. like i mentioned earlier, i've been on this thing non-stop since this morning, and it's just now flashing the battery symbol at me. i imagine once i go through a couple of full cycles, and the new toy factor wears off, it will be a non-issue (for me)

Why not just buy some extra batteries? I picked up 3 extra batteries for when I fly so I can watch movies with no worries...
I get great battery life on my Vibrant. Make sure you turn off everything that you don't need....wifi, gps, keep screen brightness low and not on 100% at all times etc...obvious stuff....

Man, I have turned the brightness down to below stock, and I do have two extra batteries. But that's kind of like going back to my WM days.
After the getting spoiled on the iPhone, which would last for almost two full days with everything running, and with similar use, I really hate having to constantly think about the battery, and worry that it's going to die on me.
True story:
Someone hit my car a few days ago and I tried to take a pic with my Vibrant. It was in late afternoon, so the battery was at 15% I guess -- so the phone effectively told me to "F*** Off." Or at least that's how I took it No pic, of course.

I hear where you're coming from...have you tried switching out the battery to a different one? I know that some of the batteries were faulty and gave people horrible battery life.
The iPhone also ran at a much slower clock speed and it was equipped with a pretty good battery. There's no denying the awesomeness of the iPhone battery...I'm just thinking that you may have a bad battery. Try changing it out.
There's also a 2800mAh battery pack coming out very soon....it may suit your wants and needs...
The iPhone also lacks widgets and multitasking - and the screen is not as bright so those all help in maintaining battery life.
If you crippled your android in the same way - you could get 2 days pretty easily as well.

Very true...
It's like a Geo Metro vs. Ferrari ...hypothetically, if they had the same size gas tank which one would consume more gas and run out faster? It's obvious...

Come on now....
I have both, and they both have their good points and bad points.
The battery is a bad point for the Vibrant.
The screen is the best point (it's actually not "brighter", but has much better contrast than a backlit LCD). I keep the Vibrant's screen at it's lowest brightness, anyway.
But in terms of speed, there is really not much difference in daily use - if anything, the iPhone 3Gs feels a little smoother much of the time. Again something Froyo might improve.
My well conditioned battery is at 5%, after 16hrs 54 min., with very light non-call use today (calls are at 49 min. 26 sec.).
My point is, that I have to expect more after using the iPhone, while some here are obviously happy with it. But it ain't great.

We get five to six hours of display on with this phone. That number is perfect if the phone was on 35% precent or more of those 16 hours.

It's ALL about the apps you use.
My battery life is pretty good, I can go two days with moderate phone use and my normal heavy-e-mail and occasional messaging usage. I don't do much web browsing with it, but I fiddle with it constantly throughout the day.
My friend couldn't get through one day on his, so I encouraged him to play around with some of the apps he had that I didn't, and now he can get well into day two before it gets low enough he wants to recharge.
My wife complained about her battery life, and I realized she was pinging four e-mail accounts once per minute. Just cutting that back to a five minute interval made a huge difference.
Even so, I've ordered spare batteries and a charger since I travel often and a missed call could cost me a lot of money, and they're too cheap to not keep a few around. (In one of those other threads somebody linked to an ebay deal with two batteries and a charger for 8 bucks.)

or he's got a bunch of widgets.
That's almost universally a theme when people complain about Android battery usage.
Got my replacement Vibrant yesterday afternoon, charged it full while turned off and took it out at around 9pm. Worked on it a little last night and today installing apps browsing and about 60 min talk time so far.... 3PM and still got 30% left.
Definitely much better battery life than the one I had on first phone. I did get a replacement battery as well, but haven't tested that one yet. This one so far is working as expected.
I haven't rooted yet so I am not sure if that and lag fix has any affect on the battery.
Also ATK is not installed yet, and i hear it has adverse affect on battery. Is that true?
what do you guys see on the battery code?
G7, G8 or G9?
I haven't really done anything different, but my battery life in the past few weeks has just gotten better and better.
Right now it's 3pm. I put in a fresh battery at 9pm last night. Batt level: 55%. I was asleep for 7 out of those 18 hours, but I've had wifi and BT on the whole time. I've read and replied to 15 emails, maybe 10 texts, 15 min of calls, surfed the web for 2 hours, played about 30min of games, and had music streaming for 1.5 hrs. I've easily been making it through long work days (8am-8pm) of moderate/heavy use, whereas before I would need to recharge after 6-8 hours.
Anyone else noticing better battery life after the first few weeks? (of course, it might have to do with the fact that I'm playing with it less, but there are days when I play with it constantly and it's still doing better than 12+ hours)
I'm still on the first week with my current vibrant and I have noticed a slight improvement in battery life since I first got it--the fact that my life is pretty consistent day to day (phone-wise) helps me track it. Maybe the hardware and software need to be 'broken in' per-se?

Yeah, it does get better, but 12 hours is not good enough nowadays -- if you go to dinner after work, the battery will be dead before you get home.
This is my biggest gripe about the Galaxy S -- compared to my old iPhone 3Gs the battery life just sucks.
I am hoping that the efficiencies that come with Froyo will squeeze a few more hours and make it usable for a full day.
If Samsung gets off its lazy (or incompetent) butt and upgrades us to Froyo soon, of course.

The question is, what are you not doing? We can all get it to last the long, but this is a smart phone. I cannot afford to treat it like if I was stranded on an island.
Before I get into my post I just wanted to say I'm running stock out of the box with no root/ROM/etc. Just plain ol vanilla Eclair...with the JI5 via Kies.
I'm getting about 32 hours myself. I do use tasker to set up profiles only to turn things on when I want them. Such as sync will only be enabled for specific apps when I run them then off when I close them. GPS is only on when I run Maps/Yelp/any geo-aware app then it turns itself off. Turn on silent mode/vibrate when I'm at the office by recognizing specific cell towers...stuff like that.
I also disabled "Use Wireless Networks" under Location & Security since Google says it will use it even when the phone is off. I don't know why but it's been saving on battery too. I also don't use any task killing app such as ATK since I think the phone should be smart enough to manage the memory by itself.
edit: Oh, I use automatic brightness settings too with manual brightness control on the browser (usually on low-med setting)

I'm at a point of consistent battery life of about 13 hours of moderate to heavy use. Been this way since about the middle of August. The longest I've pushed it was close to 21 hours but i'm normally in the 11-12 range.
Glad your phone is leveling out though

Nah it's not any different from when you first bought it, you're just using it less, even though you think you are using it the same.
Trust me, when people buy a new phone, the first few days or couple weeks they can't take their fingers off the phone, and it appears battery sucks. As you get over your new toy phase, you don't play with it as much, and magically you think the battery has grown new cells.
bye.

There are easy ways to take care of this if you really need better battery life. First, call T-Mobile and complain that battery life is shorter than advertised. They'll walk you through a script and send you a free spare battery. Second, get an external battery charger. They're all over ebay for about ten dollars, and most come with generic spare batteries.
I've now got a charger and three batteries, so I can pretty much make it through an entire work week without worrying. (You couldn't do that with a 3GS!)

I get nice battery life but I use it too much, then "a day" is from 5am to 10pm, it's just too useful, and when you check usage, it's 75% display.
36 hours would be easy if I limited my screen on-time....while I would like a UV kernel it's likely not helping enough. My display is on lowest, yet I'd love a lower setting.
Aside, the more background services check stuff while screen is off, battery life hours down.
Overall, I am VERY happy with the battery life.

You must be one of the few 3G/3GS users to never worry about battery life. Most of the users I know have (or had) to recharge mid-day, a pain in the butt since the battery is not removable. Your 3GS has a much slower processor/GPU, and a smaller screen with a quarter of the pixels; but even then, google "iphone 3gs battery life" and you'll get page after page of reviewers and users complaining about the abysmal battery life.
(of course, someone here claims that his Vibrant can go 40+ hours, so maybe your iPhone is a similar outlier.)

Its exactly what the problem is. When I flash a new rom I spend 30minutes getting back to the way I like it and my battery suffers from it. When I actually use my phone like its intended to be used I get great battery life.
Are you using any kind of ROMs? I think some ROMs greatly improves battery life.

Should? Says who? The phone is pretty average for its class. You can either complain that things are not the way you want them, or you can adapt by carrying around a diminutive spare battery....

...You must be one of the few 3G/3GS users to never worry about battery life. Most of the users I know have (or had) to recharge mid-day, a pain in the butt since the battery is not removable. Your 3GS has a much slower processor/GPU, and a smaller screen with a quarter of the pixels; but even then, google "iphone 3gs battery life" and you'll get page after page of reviewers and users complaining about the abysmal battery life.
(of course, someone here claims that his Vibrant can go 40+ hours, so maybe your iPhone is a similar outlier.)

Dude, I've had one iPhone 2G and two iPhone 3Gs. I also have two Galaxy S variants (international and a Vibrant).
There is no comparison between the iPhone 3Gs and the Galaxy S in terms of battery life. With the same kind of usage, the iPhone 3 Gs would last about 32-37 hours, while the Galaxy S would last about 12-13.
Even the iPhone 2G lasted about 18-20 hours. Now, compared to my previous HTC WM6 and WM6.5 phone, the Galaxy S does have longer battery life, but that's nothing to be so proud of.
The Galaxy's screen is certainly better than the 3Gs's, but the Super AMOLED is supposed to be more efficient than the LCD on the iPhone. Plus, in real world use, the iPhone 3Gs certainly feels smoother than the Galaxy S, even with the lag fix, and scrolling on the iPhone is smooth as butter, while the Galaxy S is choppy.
And it's not just the OS, because the EVO scrolls noticeably smoother than the Galaxy S.
I consistently get 20+ hours out of one charge. I can't really use my phone at work, but during breaks and lunch I'm always getting on it and checking mail/feeds/youtube or whatever and still have about 70% by the time I go home. I usually have more than half by the time I go to bed unless I've been doing some tethering or heavy audio/video streaming.

lol...thats so true...
Can anyone tell me why the Android phones have battery life issues? Here's a scenario...my friend has an iphone, i have the fascinate. We both put our phones in our locker in the morning for work. We both come out for break and he still has well over 90% of battery life while mine is down to 70%. Why do the android phones drain so quickly. Yes I could put it in airplane mode and such but my friend doesn't have to on his Iphone.
Just wondering why these phones have such a tough time with battery life. I notice in a lot of the forums people are trying different things to get better battery life. I have tried different roms, kernels, radios, etc...and really don't notice a huge difference. I am not a heavy user of my phone and it lasts just about the day and dies. I may hit the net for few mins, do some texting, and check email from time to time. I would think the battery should last a couple days just doing this...not drain when the phone is just sitting idle. Anyway just wondering about this.
Apple has complete control over their phones. Designed in house, software developed in house, and carriers have no say in the software.
I have a feeling that has a lot to do with it.

Which ROM? Of course you are aware of the many workarounds needed to keep froyo idle drain under control? These will eventually be fixed for good.
I have even more of a complaint about the active screen-on drain. Using auto brightness indoors, its impossible to get more than 2.5-3.0 hours of screen time. (WIFI or 3g) This is way less than iphone 4's capability of around 8 hours. There are some things that help explain it like androids 100% cpu usage when scrolling or animating the UI. However, there must be massive differences in the screen power consumption. Yea, yea, SAMOLED, power draw depends heavily on displaying black vs. white etc, but my random usage never gets more than about 2.5 hours screen usage over a day. Say what you will about apple, but they optimized the hell out of battery life.
Which kernel are you using? After moderate usage for me (games, browsing web with wifi, phone calls, etc) my battery life is around 70% after 15 hours.

Guys, since screen-on time dominates battery usage, it'd be nice to note how much screen-on time you get and your brightness setting. Defining "light" usage over a number of hours could mean just about anything... very subjective.

True enough. I set my light to auto and since im usually in a room, the light setting is at lowest. When im outside, its goes to the brightest settings.

If you use Google Navigation and constantly force rerouting to destination by taking wrong turn/path, your 100% charged phone would hit empty within 2HRs or less with the screen brightness set at minimum.

We have a more powerful phone than the iphone 4, of course our battery is shorter. (better screen, faster cpu, etc) Also seems like our antenna is the best according to the review.
Android is made to constantly sync with the internet for updates and notifications. It's just the nature of the operating system to draw a lot of power because in theory it is a more powerful and complicated system. Also keep in mind that the battery inside an iPhone is huge and it is lithium polymer which lasts longer but is more expensive. These larger lithium polymer batteries are the main reason iPads and MacBooks get good battery life as well as their less powerful chip sets.
EDIT: Oh, and also iOS doesn't use as much RAM as Android so that also factors in to the battery life being generally better.

I appreciate the more open, easy to modify nature of android over apple. But to trying and explain the 2x worse battery life on android as arising from "better" processor and screen is wishful thinking at best... blatent android fanboy propaganda at worst. We need to learn how apple has optimized things, not turn an overconfident blind eye.

It's unfortunately that the Fascinate lacks the monthly software update support similar to Apple, but using the support from this forum by the devs, I had achieved 1% power usage for every 3 hour idled = max possible 300 HRS.

Guys, there's a lot of android fanboy propaganda going on in here. I'm not against android, but don't automatically defend it like its your mama. The ifixit link below shows iphone 4 has 1420 mah battery as opposed to fascinates 1500 mah. They also both have 512 MB RAM. So that's not the issue.
Also, the Anandtech tests were done with phone on and active. So are you trying to explain android was at a disadvantage because it was "doing things in the background"? Like what? Any background process or sync service that kills your battery that bad is implemented horribly. iOS is doing the important stuff in the background too... maybe just not the ESPN or weather widget. But no one in their right mind believes those things are the problem.

Sadly, I am the opposite of an android fanboy as I would have gotten the iphone for verizon asap if I havent gotten the fascinate back at November. (Iphone on Verizon were still rumors back then). Also note that review was done in October last year. Battery life is probably much better now with cleaned roms and froyo.
If you really need to browse the web over 4 hours a day on your phone (use computer?), why not just get a larger battery or even get the iphone?
Edit: Hardware mean a lot in battery usage. After checking the iphones CPU, seems like its pretty much the same or similar to the ones of the fascinate, except slower clock speeds.

Personally I don't get any better battery life from froyo ROMS. My wife's fascinate with stock eclair usually gets as many if not more hours of screen time as I get with superclean 2.9.2 and jt's EC10 w/ slight undervolt. Sometimes I get much worse battery life when I forget to activate one of the 10 workaround hacks still needed to fix the idle drain issue.
I use 2.5 hours of screen time daily quite often and find my battery exhausted before the day is over. Maybe I'm the rare case, but I doubt it.

My battery life with imnuts undervolted kernel is much better than ones from previous EB01 kernels. I didnt find much difference between SC 2.9.2 ROM and Nameless V3 battery with the same kernel. I usually have around 75-50 percent battery life left from moderate usage. (Different from other people according to screen brightness and etc as stated in previous posts)

Under battery details, what is your display "time on" at end of your day? What is Max "time on" you ever got? Without those numbers its hard to say anything objectively.

Since its monday tomorrow, ill test the max time on. At the end of the day, or rather when I start charging it again/installing kernels or roms, time on is 14 hours and 17 minutes.
On my fascinate I unplug phone at 645 check face book and xda for about a hour on auto brightness. I then go to school and check pulse and xda many times totaling around 2 hours. The rest of the time is idle so after 2-3 hours of screen time and then 3-4 hours of idle during the school day I get home with 85-89% left im using dark revenge with imnuts undervolted kernel. Im no android fanboy I'm just posting my stats.

I'm beyond impressed with this phone in the 48hrs I've had it. Coming from a Pixel 3 and S10e, upon first powering on it felt noticebly jankier than my other phones and understandably so. But after initial setup and allowing it to settle, it's actually pretty snappy. For my use case at least- web browsing, Twitter, Reddit, etc. PUBG is playable, but I'll leave that to my 3xl.
But what is blowing me away is the way this 670 sips on battery. It took me way longer to drain this thing than I thought it would, but between yesterday and today I managed almost 9hrs sot. This was just here at the house, 100% wifi, adaptive brightness on, and aod on. I'm curious what it would do with aod off, but at this point I'm sufficiently hooked on that feature. This is far and away the best battery I've ever had on a phone and it's truly plenty snappy. A step behind the 3 of course, but I'm good with this and the gains in battery are more than worth it. I honestly don't know who buys a Pixel 3 at this point.
Caveat: digital wellbeing was turned off before this test.
Bought unlocked at Best Buy. $399 with a $100 bb gift card; effectively $299. Crazy good value. It feels like Google just decimated the mid-range market.
BTW, the clickiest buttons I've ever had on a phone. The buttons seem oddly high quality for a phone this cheap.
I'm getting about half that with the XL but it's expected, I'm cruel to my batteries. I do agree about the value statement. When day one deals have the phone widely available for 100 (or more) less than MSRP you can figure that's your real buy in price and at 300 and 380 these things are screaming deals. You've got a top notch camera, a good software experience, best update path available,etc. Not an easy combo to beat and I'm very curious about where the sales numbers are going to come in at on these things. Personally, I'm hoping their good and we'll see more of the same.

I think this phone will be very popular. I don't see any reason it wouldn't have a strong development scene as well.
Yeah, I've been over optimistic about some phones that didn't do as well as I expected so I'm a little more guarded now about taking guesses but that aside I see this one as a winner. It's a very compelling package in it's price point.
I gotta give it a pretty good on the battery too. My 3a (small version) arrived on thursday.
It's clear it's gonna be able to consistently do 2 days for me.
Couple hours of PowerAmp via BT, which is a fairly power hungry use, plus 2:45 hours SOT (barely any overlap between the music and the screen use, by the way), over 12 hours with 57% left, good enough as far as I'm concerned..
Quite satisfied with the phone, happy to be back on a "Nexus" (the 3a feels so much like the spiritual successor to the Nexus 5X I knew it'd be the phone for me. I was right).
If next year they make a 4a with small bezels and the same or just slightly bigger screen size (so a slightly smaller overall size), I'll be all over it, almost guaranteed to stay with me for years.
Pixel 3a XL user. I'm not a heavy user but unless something changes I charge the phone every other day. I am on day 2 about to call in quits for today with 34% charge remaining and SOT of 6 hours and 30 minutes. Will put on the charger tonight. I really don't want to start charging the phone when it has over 60-70% charge remaining. I may start charging the the phone to only about 80%. I do that for my laptop because it is supposed to improve battery life. I hope that the excellent battery life continues.
Anyone know if ambient display affects the battery life noticeably? I heard some Pixel 3 owners are complaining about 1-2%/hour idle drain when its on, I hope it's fixed on the 3a.
I'm coming home with 80% battery left where it use to be 20% on my LG....This phone is awesome.

Yes aod is very battery hungry.
I lost 12% over night (8h) .
For me aod is a deal breaker so I turned it off for more battery life.
Overall the battery life is extremely good on my previous oneplus 3 I barely had 4 - 4,5h sot (with all tweaks).
Now I get 8-9h sot so I'm pretty impressed.
With root, substratum and blackedout apps I'm sure the battery life will get some significant boost.
Oh and the idle drain is also very nice, no deep sleep issues. Now with aod off I loose over night 0% yes zero

I'm assuming that's using airplane mode or something no?
I'm liking sofar but I got spoiled by my last phone's battery (Mate 9) At least I'll be getting updates though! I have ambient display off and I have a watch connected and a bluetooth earpiece on about half the day. I haven't not kept on charge when I knew I was going to be away from the home for sometime but it does seem like it will get about 20-22 hours on the battery at my usage level. I'm happy with that.
I have been pleasantly surprised by my battery life with my 3a. Best battery life I've ever had on an Android phone, at least in recent memory.

That was one of the first things I've done. Pretty much all these 'fun and useful' features I've turned off as my phone is 90% of the time in my pocket. I reinstalled Naptime and Greenify, to get it to doze faster.
I just flashed ElementalX Kernel, so we'll see if that helps any.
I don't know why you can used for 9hrs SOT, but I think the average SOT might be 6-7hrs in wifi condition, although it is common, but concerned about its 3000 battery, that's fine. Anyway, how is your setting for that
