Amoled murders battery? - AT&T Samsung Galaxy S II SGH-I777

What is the deal with this phone? The battery life is not very good at all. I came from a phone that had a 1150 battery and this one has 1600! I am getting almost identical battery life as my old phone. I am running a fully debloated rom at stock clocks with the display turned all the way down and can HARDLY make it through an 8 hour work day. I've narrowed it down to the screen.
I remember reading about amoled when it was first announced and they said it would consume significantly less power than any other display technology. I'm starting to second guess this.
Its either the screen or the dual core processor that's draining this decent sized battery so fast.

I've been getting 12 hours on batter with almost 6 hours screen on time. Heavy usage. Every day. Better than my iPhone 4.

Amoled does. From what ive beem read ing super amoled plus.is alot better. The darker the better. Slcd is.a.good option for battery mizers though.
I voided my warranty and your mum.

Yes ive also read that the way super amoled plus works, is there is no backlight and individual pixels light up, so its better to have simple wallpapers with mostly black, would probably give you better battery life, as most of the screen will no be using any energy.

All android devices murder their batteries. It's nothing new get over it lol.
This device gets decent battery life considering it's the most powerful option out currently though.
The general masses do not understand how to set these phones up for optimal battery life. There are threads all over XDA on how to do this.

This phone for android is probably the best or near best in its class. I am impressed. Its better than my captivate was. I can get through 15 hour days with heavy use all the time with average of 4 hours screen time and i listen to a lot of music when the screen is off. This phone rocks i dont even see the need for a extended battery

I have no idea what you do with your phone or what . But I get more then enough battery with this phone, I do it all text talk surf web forums play and I make it home with enough battery to probably lend you some. Seriously we all know your not going to get iPhone battery life obviously the iPhone it just plain simple. But come on, this type of thread it's getting annoying there's a few already with help and tips on your issue search for them. Maybe you just got high hopes, or maybe it's not the phone it's you. BTW Amoled probably consume less battery but not enough for us power hungry users to see a different.

I don't think is the screen alone itself but the dual-core running at 1.2Ghz might eat more battery than your old phone with an smaller battery

You might want to install CPUSpy and BetterBatteryStats (BBS) so you can better diagnose where your battery issues are coming from. 8 hours seems very poor for this device. Use CPUSpy to see how much your device is running in deep sleep - with light usage I usually see around 80% deep sleep. You can use BBS to look for apps causing excessive wakelocks (BBS is available here on xda) to see if a particular app is causing the problem.
Unless you have a hardware problem, I don't think the display is your problem - the display on this device has a smaller percentage hit on battery use than my 3.2" LCD Aria.

Yet you've completely ignored people who have told you to get CPUSpy and BetterBatteryStats to figure out what's keeping your phone awake.
Most likely your phone is not defective, but you've installed an app that's hogging the battery or set up a configuration option that kills it, such as:
Hotmail calendar sync is known to cause massive battery drain due to a Hotmail server side bug
Some Exchange servers are misconfigured and cause major battery drain
Skype is a battery-hogging nightmare. If you absolutely have to use Skype, make sure to take it out with a task killer when you're done with it.
I haven't really pushed my device with screen-on time, however what are your idle battery drain statistics? If you have drain more than 2-3% per hour when the phone is idle (such as overnight), something is very wrong. You should be getting drain on the order of 1% an hour if you leave the phone overnight in moderate signal.

I havent ignored anyone. You assume that because I haven't responded to such comments that I haven't tried them. I frequently use cpuspy to make sure my phone is sleeping and I use bbs as well.
I'll leave the phone off the charger overnight to check it out though.
This still doesn't change the fact that HEAVY useage at 5+ hours of screen on time is absurd.
I am also planning to experiment with airplane mode and using only wifi tomorrow.

Make sure to do the following to get the most accurate data:
Top off to 100% (to the point you get the full-charged notification)
Remove from charger
Reset timers in CPUspy
Put phone down and go to bed

You can still exchange with a new one under 14 days or 30 days. 6 hours with screen on is not absurd on this phone in 12 hours. I have been with screen on with 2:45 hrs and voice with 45 min in 1 day and 8hrs with still 15+ % battery juice left.

IIRC, one of the review or comparison against iPhone4S benchmarked GS2 as 5 to 6 hours of internet browsing which means both screen on and using data. Wi-fi gives it a slightly longer battery life than cell data. Unfortunately, it didn't benchmark video playback time. iPhone4S spec says 8 hours of video. I hope GS2 is close to that. This is play video from local storage, not streaming. So, the data connection battery draw is out of picture. I managed to get 4+ hours of video playback with flight mode on with my old Captivate. Hopefully, GS2 will last longer, e.g. survive a coast to coast flight while still have some juice left for navigation.

He's not lying. I have seen 5 hours of screen on time and still had a little juice left at the end of 16 hour days. And it wasn't a one time deal. Seen it several times, though I usually don't use my phone that heavily. Yesterday I barely used my phone at all and was only down to like 85% after 16 hours.

Battery issue

I know this topic is always repeated but I fly I should havr made a thread anyway. This morning, in 15 minutes of web browsing, I lost 3% battery. In 10 minutes, I lost 2%, so it seems to be progressive. I just got this phone Friday.
That can't be normal, is it? I don't want to return it but I will if its a bartery issue. Could it be as simple as buying a new battery?
Sent from my SAMSUNG-SGH-I717 using xda premium
Most people report good battery stats. Give it a week and see if it settles down. Might need a few recharge cycles to level out.
As mentioned, the OS needs a few power cycles to generate its Batt Stats to give you a more accurate baseline. Also if you need your device to last all day and into the evening with no supplimental charging, you may want to look into taking certain measures to ensure your battery life is sipped and not gulped. I am not sure your level of experience or you tech knowledge, but basically anything having to do with comms is going to suck life. BT, wifi, 2g/3g/4g, and gps are what we’re talking about. You can manage these manually or use apps to do it for you such as Juice Defender and 3gWatchdog to name a couple. My office is in the bowels of the building where reception is spotty. The first week with this phone, my battery was at 40% by lunch time. This is because it was constantly searching for signal and when it did get one, it was being forced to high power to maintain it. Since I really don’t use my handset much in my office, I decided to take drastic measures to see what could be done. I installed the previous mentioned software already to keep my data use under control (came from a unlimited plan sucking down 8-12 gigs/mon on average) so with a few tweaks it was set to assist me. So when roaming my building I check it occasionally and when in my office I switch to airplane mode since I have my email in front of me and I use Google Voice to ensure all my calls find me no matter where I’m at. I arrive at work at 0700 and stay charged in on my drive to work. So at 0700 I was at 100%. I switched to AP mode after 15 minutes of typical goodmorning watercooler talk. At 1200 I looked at my Note and it read 99%. I went to lunch and opened all connections up while in our cafateria and after 45 minutes I was down 5% with comms going and lots of email and FB browsing. I’m back in my office and still at 95%. Obviously not everybody can follow the scheduled use as I laid out, but it works for me since I don’t have signal anyways and will make day much easier when I have to do lots of running and wont be plugging in untill tonight around 2300 except when commuting. I’m hoping this trend of juice sipping continues on for the rest of the day.
Screen brightness\use also is a big juice sucker. So, with the big screen on the note you need to be mindful of that, too.
Thank you for taking your time on that long informative answer!
Asides, today at school, my phone was on complete idle standby with lowest possible brightness and Wifi off (but mobile data on) and by 2:00 (6-2 so 8 hours) I'm down from 90% to 75%.
Is it defective or is what I'm getting normal?
Edit: Forgot to add I have a Tasker that disables mobile data when turning the screen off.
Edit 2: The Tasker profile is for the screen facing down, not being off.
Still, is that not a lot?

What are you complaining about those are great numbers. Losing 1% every 5 minutes means 500 minutes of screen on time, which is 7 hours and 10 minutes. Remember that's just with the screen on. With the screen off and sitting in your pocket you will lost about 1% per hour.
2g/3g/4g...each step you take the worse it is on battery. Restrict to 2g (edge) if you arnt downloading or doing anything. There's lots of toggles. What Juicedefender does is kills the connections untill you turn the screen on and I believe periodically between screen ons to pull any texts and such. The weaker the signal strength (bars) the more battery its using in order to stay connected. Try a few things and you'll be surprised at how stepping in a little to restrict its juice use will make a difference in battery life. Plus, as mentioned, give a few days to build those batt stats up, then it will give a more accurate measure of the current capacity.

So you lost about 2% an hour. Typically you should see 1% per hour. So either you were in a low signal area which caused it to use more power to find a signal, or else you last charged it with a USB charger which prevents it from going into deep sleep (known bug). Or you could have a misbehaving app.
Download CPUSpy from the market an BetterBatteryStats from XDA and see if your phone is deep sleeping and check for wakelocks.
I last charged it with the OEM Samsung charger.
Is that the problem? The reason I started this thread is because I see people reporting (yes I know) that on standby they get great battery life.
Sent from my SAMSUNG-SGH-I717 using xda premium
Every phone discharges differently, especially when new. The overall life is what's important as to whether it's acceptable to you or not. Give it 2-3 days of good ol fashion heavy use. A few good full charge then full discharge are good for getting a good baseline. I remember one of my phones would lose it's top 10% (100 to 90) in a matter of minutes of being unplugged, but then would be fine the rest of the day. This is what I mean by the overall being the important part. But the rogue app part could be something to look into. Aften when we get new phones we go hog wild with new apps with the "lets see what this baby can do" mentality, I say this because I am very very very guilty of it. Sometimes you get an app that malfunctions or is just straight BS. There some that open by itself. Some that you get Ppush notifications about buying ingame currency for and other shady stuff. I try to install only a couple apps a day to keep an eye on weird stuff happening.
Thanks for the replies everyone.
Chief Greek, are you seeing around my results or do you think it is simply a matter of my battery stats not being correct as you said?
Sent from my SAMSUNG-SGH-I717 using xda premium
I have been using my method I stated in my first reply. Here I sit about 9 hours later and my phone is at 92% with no supplimental charging.
Do you know of a way to get a 4G toggle into the dropdown menu for easy access alongside Wifi, Rotation, etc?
Those are some good stats though.
Edit-One app I do have installed is "RAM Manager" and I replaced Samsung settings with settings in app. Could that be detrimental&
Sent from my SAMSUNG-SGH-I717 using xda premium
Havnt played with ram manager, although used something called cachemate before. Seemed to do the trick when phone was acting goofy or very lagged out. I would wait a few days and see if it levels out. Keep screen off when you dont need to use it and if you really really want to do something about it now, install the free juice defender and see how you like it. If you like it and want more controls, upgrade to one of their pad versions.

I loose 1% per 20-30 minutes on standby =/ What settings do you have/how many apps do you have? Do you keep Wifi/Mobile Data on all the time? Reason being, I want to get this figured out before I root/go any further. If it is indeed my own issue, I want to to get it sorted out. Is it worth a factory reset?
Not to get off topic but are the batteries from the international version and the Att version the same? Could they be a different type or manufacturer?

I am not an expert answer on this but yes, I'd like to think so. In some cases it would not be the same (being that ATT has NFC and International does not) but considering the NFC chip is NOT in the battery, it leads me to believe that the they are the same 2600mah batteries.
So, I was just with Samsung chat agent (who probably didn't know a lot about the phone) and she said lost of 25% was normal standby. Am I the only one with this? Techntreck, you get hours on standby?

10% Battery left at this point. I started the day with 100% at 6:20am. It's 7:58pm (19:58) now. Is this bad?

Battery gets literally 4 hours before it's dead

I ,am on it a lot, between GPS and general usage, ,but this still seems like too fast to drain compared to what others here have said. I had this problem with my Atrix too, maybe i am just destined for bad luck with battery life
Do you use anything like juice defender. This app literly doubled my battery life!

Apps like that only increase standby battery life. Everything else is very minimal.
And I'm not happy with the battery life either. My phone is plugged in right now and the battery is actually going down as I use it.

This happened to me since i first got the phone it has slowed down and now the phone can last through the day ever since at&t throttled me for this month goes without saying ill take it easy next month. so most likely if your in an lte area thats the problem

If it's notbthe stock charger you areblikely not using a rapid charger.
Sent from my SGH-I717R
I pull mine off the charger at 7:00 and at 3pm or so it's down to 85%, I'll put it on the charger at work until I leave around 5-6pm (mainly because I'm used to having to do this on my previous phone) and at night if I'm not using it constantly it's around 70-75% when I plug it in at bed time.
I suspect anyone getting that bad of battery life must be using it constantly, ie: Playing games, browsing, trolling facebook, etc.. Even in the "new toy" stage I'm getting great battery life.
FYI I don't have LTE, but do generally have good 4G.
You honestly can't use any phone on GPS without external power and expect that you're not going to discharge quickly. Assuming that you are running a car charger during GPS and just didn't say so, search the i-717 threads, since the topic has been well vetted on what chargers are more effective,etc. There are definite differences.

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.
When I first got my i717 and was using it on the stock rom I had pretty terrible battery life. I take it off the charger at 5:00am and had decent battery life (around 5 to 7 hours without GPS) but I use my phone a lot for internet/email. I think your battery life is completely normal given your usage.
Most people get about 5hrs screen on time. Total on battery ranges up to about 24hrs, but only if the screen is off at least 19 of them.

i can get about 3 or so
5 hours of screen time AND 19hours standby sounds incredible
would sure like to see screen shot as well
and def dont think 5 hours is any type of avg
I had GPS running on my phone for 4 hours today, had blue tooth on half the time without knowing it, sending text messages, making two 5 min phone calls, checking maps, checking FML and reading a book for about an hour and drained down to about 70% and I have the brightness set at auto. I would exchange it for a new battery.
On average with several texts per hour, several 5-10 min phone calls, taking a few pics and uploading them to picasa, checking facebook, updating status and checking emails I can pull off the charger at 630am and still have 50% battery (at least) by 630pm.
I do have the juicedefender (which isn't crap, it turns off signal after so long so you aren't trolling for signals when you aren't on the phone).

I have to charge around 7-9 everynight at 4-4:30 hrs screen on, but my use is pretty heavy. I sync 4 gmail accounts, a separate GV, 3 calendars, and several apps.
If yours is much worse than that, you likely have a few troublesome apps or are playing games. First, after a full charge, reset cpuspy timers, lock it, and set it down for a few hours (I know, impossible). Then check to see that your CPU has been in deep sleep about 95% of the time. If not, use better battery stats to see what has been request wakelocks. Not only the most total time, but the total number. Any app that looks outrageous, freeze it or uninstall it. For system processes that look troublesome, Google. You can often find simple tricks online that will tell you what's causing them to go crazy. Beyond that, turn off syncing of anything that isn't needed or doesn't matter (like Facebook), and uninstall stuff you never use.
Another slight help is the brightness widget (don't use the actual widget, just put the app on your homescreen, it works the same) or dimmer in market as they can both set the brightness to a value of 10 (Samsung lowest stock is 20), and even if you can't tell the difference, it helps. Jkay settings in saurom can set the auto brightness profile slightly darker than stock. Umm, and the obvious, use less Widgets, longer sync intervals, processor scaling and speed profiles, and buy a couple rapid chargers, wall and auto.
A couple things to note after seeing a few of these posts...
BT can be on, but without it searching, connected, or listening it's not active.
GPS isn't active unless its in use aand you see the icon in the notification bar. That being said, fb, websites, and many other apps that request location will activate it.

YOU MUST CALIBERATE THE BATTERY!! I have no issues I use my phone heavy all day and get 15 hours and I still have 20% left. All you have to do is
1) Charge you phone until it says "charged"
2)Leave phone plugged in and power off and let it charge until the battery meter literally says "100" (screen will sleep so you can check with volume rocker to light screen)
3) power on phone and let boot and than power off and wait till you see 100% again
4) now keep doin this and you will notice it will start displaying "100%" faster and faster usually takes 6-7 times cycling like this
5) After you do this download Battery Caliberation (root required) app from market and hit the caliberate button and boom your good to go
I do this on every android phone I own when I flash a new rom or purchase a fresh one. Everyone should do this everytime you flash a new rom and I can CONFIRM significant battery longevity on all my android phones I have done this with
You only have to do it once so just get it out the way and you'll get through a whole dayand have some juice to play with.
I get 15+ hours and do not any battery juice defender apps

The fact that there are people out there that get really good battery life means the problem is you and not the phone. If you refresh facebook every minute of course your battery life will be crappy. apps like juicedefender are just marketing crap. as long as there are no running apps in the background that eat your battery, you do not need any juicedefender or tasker. also setting screen-off behavior to conservative on set cpu helps improve battery life.

Just to be clear here, Tasker has nothing to do with battery life. It doesn't hurt it, nor "help" it. However, you certainly could write tasks/contexts that would decrease battery life, and there are a few scripts out there which do silly stuff like autokilling, etc... But if we're talking "battery savings", Tasker and JD do not go in the same category.
IMO JD is only useful if you're frequently in an area with no signal, like you work in a basement or deep inside of a solidly constructed building. Since you mentioned Tasker, in this context it does help me a bit on battery because my wifi turns off when I leave the house, but that's also something JD can help with. If you don't have a wifi connection it'll turn off wifi (and I believe turn it back on periodically to see if there's one available?) I don't use JD, so can't speak too much for it.

Hour? Hour and a half? I'm working during that period. I usually hit news sites and G+ when I'm first at my desk in the morning, so that's 30 minutes or so off and on looking at it, then perhaps an hour over the rest of the day, sometimes more at lunch.
I'll look closer today and post back.

Battery Stats HOX+ (AT&T)

We should generate our own thread with battery stats for the AT&T version of The HTC One X+ because we have the LTE version. I expect that our batteries will drain faster. I will post my stats as soon as I am through my 3rd charging cycle. +/- power saver will be interesting as well as overnight in sleep mode. I normally don't optimize a lot to keep my battery drain low. My GNex made it without a problem through a day and night.
I'm on my second cycle and the battery has been exceptional! 1.5 days on a single charge so far.

Really? I barely make it through 13-14 hours. Do you use the battery saver function? I will post some screen shots later.
I can't give you any good battery data yet, as I just got home from the store with it and I've been busy setting everything up the way I want it and installing apps. I was, however, very surprised after installing CPU Spy to see how low the processor will slow down...

6 hours with slight/medium use and I am down to 50%: No battery optimizations. Screen is on auto-brightness. I will use better battery stats to get a better idea what drains the battery. I burn 10% of battery/hour with light/medium use that's too much.

Interesting. If I look at better battery stats CPU states the lowest my phone is going to is 475 even though it could go low as 50. Have to run the stats for an entire battery charge to get some useful information.

So I tested again today and my battery performance is still bad I would say. Do you guys get similar result otherwise I will try to exchange my device. I didn't do anything special. I played 5 minutes riptide. Took some photos without flash and posted some stuff on facebook and XDA. Screen on time is low 1.5 hours. and I have only 28% left. Do you get similar result or much better battery performance?

If I open better battery stats the overview is on the first screen I see. You only see it when the phone is not charging. You have to wait a while until it populates with data. No root necessary. Try to switch the view from since unplugged to since charged and back. That might help.
Interesting. I got my replacement device yesterday and I ran better battery stats: My battery drains now only 5%/hour instead of 10% and the CPU clocks down to 50Mhz while not in use. My first HOX+ never went below 500Mhz. Looks like not the battery was kaputt but the CPU had some issues I would say.
It's seems as if I'm now getting a average of 20 hours so. Constantly on wifi, a couple calls, some email and light gaming. I have to say coming from the vivid I'm highly dissapointed. I was expecting not to constantly feel like I'm tethered to wall but that doesn't seem to have changed.

20 hours on battery power makes you constantly feel tethered to the wall? I think your expectations are a bit unrealistic. You're on a quad-core device with a huge high-def screen. 20 hours seems very reasonable to me. Charging once a day is pretty standard for most modern portable devices. I think 16 hours is about the target I look for, that way it can be plugged in when I sleep and run unplugged the rest of the day.

Yes, that's pretty good. I am satisfied at the moment too. I get 15 hours with medium use (texting, facebook, music streaming via BT and internet) and 2 hours screen on time.I am just on my 2nd. charge cycle so I hope it improves a bit.

i don't think this impacts your kernel. Kernels modify how the hardware talks with the phone. This app is the contrary, it impacts how the software talk to the phone. I think its worth a try either way
In any case, i installed the app earlier, it takes about 2 days to learn my behavior, i will see how it work in a couple of days and i'll report back. Usually, i can get a full day of light to moderate use and still have 30 - 40 % when i get home. we'll see with this app

i think hes talking about fauxclock and fauxsound. I wouldnt pay for that, but i do trust the developper as hes been the best kernel maker since the S2
mine just got out of learning mode...will check back in 48 hours with some stats
this is why you pay for a kernel tweaker ,and thats overclocked to 2.1 and screen time of 2 hours and talk time of about 1 and half hours and still have 22 percent to go that will take me over 24 hours, ohh and i just started using battery guru yesterday still in learning mode
Interesting app, installed it and will test it over the next few days.
This should have come integrated with all factory roms, instead of gimiky junk.

tbh 24 hours with 2 hours screen on is not that good. If i dont use wifi, just LTE every day i get 24-30 hours with about 2.5 hours screen on thats OC'ed just a tad. Now using wifi as much as i can i can get 5-6 hours screen on same time frame...

While I completely agree with you that it should have come pre-installed, there's also the chance that this, too, is a gimmicky app! I've got 4 hours left in "learning mode," so we'll see.... I'm already getting incredible battery life, so I don't have much to complain about!

F you for seeing the point in supporting devs. I spent 7hrs straight last night debugging my aospa build - all for free - no charge to you. Thanks.
well, very interesting results. I've been out of learning mode for about 2 days, and i have to say i really see a considerable difference. First, i would just like to point out i'm not a HEAVY user, more moderate to light. I'm an insurance broker, i'm on the phone from 9am to 5pm about 80% of the day (on land line), so my screen time is about 1.5 hour at 5pm, i mostly check social networks, emails, tapatalk, some youtube vids during breaks, my apps update automatically during the day. On a good day, i come home with 40%, on a day of heavy usage, about 20%, i'm always on lte tho. I also never disable wifi, bt, gps and most other features.
Today has really been the determining day because its the first day the counter was on. When i came home today, i had 1h17 mins of screen time and.................................68% left!!!! Then from about 6pm to about 30 minutes before bedtime bedtime and adding an another 30 mins of screen time (1:00am EST) i lost an extra 15% to bring me down to 53% just before i plugged it for the night. Thats a HUGE improvement. The great thing about this is that all day, i received all my FB notification instantly, all my emails and other stuff. I have not seen any cut in functionality.
So this phone was unplugged at 7am this morning, and in 17 hours, with just under 2 hours of screentime, and light to moderate use, i lost in total, 47% of juice and i didn't notice giving up any functionality.
I have to say i'm impressed. I hope this was not just a really good day, and that this app actually was the reason for the improvement.
myn came out of learning yesterday i am using fauxs kernel too but this is light usage but still this is great,14 hours and still at 78 percent wow
Mine came out of leaning about 10pm last night. I noticed using power saving mode helped a lot without sacrificing normal performance just using apps and checking messages and stuff. Standby with batteryguru my idle almost flat line which helps a lot. Usage with power saving on and off with battery guru was almost the same. Battery just seemed to stretch. Automatic brightness also seems to work better. Before battery guru kicked in auto brightness was all over the place or did not work very well, more of not working well. Now auto brightness is fairly consistent though the delay us often 1-5 seconds. Still much better than before. It also seemed to get better battery life with my at&t sim rather than T-Mobile. I think part of it is T-Mobile bloatware running in the background and probably the better reception. But in tmobile's defense I do have to say I am impressed with the network. I am seriously considering switching to T-Mobile now. Their dc hspa+ and lte were both fairly consistent at ~10mbps with low latency. Also am getting much better signal at my apartment. At work is a mixed bag though. Hard pulling signal in the reception challenged places where in would get a signal with atnt. At&t lte though is much faster. Hardly dipped below 10megs and often got 20-30mb/s. I am going to return my gs4 though and see what the Google edition brings. I have some issues with mine that I can't isolate to hardware or software any further unless I root and I won't do that becuae I haven't committed to the phone yet. Also have a two tone screen. One side is darker than the other. Was not a big deal until I started noticing how bad the black crush was on the darker/left side and loss of details in videos. I was not actively looking for this loss of clarity either. After extensive display testing now I can't shake the obvious disparity and hope i get abetter screen if I get a Google gs4. Anyways, went off topic, but battery guru is the real deal. Very noticeable.improvement in battery and phone got less hot and took longer to get to a borderline warmth level. Definitely worth looking into this app to improve battery. With the right tweaks, root access and optimizing some of the apps for black background (why the hell samsung went back to white backgrounds like email have no clue) this phone could probably get 6h in a heavy day of usage easily, provided no GPU intensive apps/games are played.

Just some stats since downloading this app and it being out of learning mode and I'm amazed.. I normally get about 12-14 hours no charge with about 30% left.. Although I did put this on the charger for about 20 minutes last night the last full charge was 4pm yesterday and I'm just now putting it on the charger at 12pm today.. Now one problem is it learns how you use your phone and adjusts to your usage, that said, I work from 430pm to 430am Monday thru Thursday and 430 till 2am at the latest on Fridays so my phone isn't on Wi-Fi in those hours so when I got off work early last night this app automatically had my Wi-Fi off cause the 2 day learning period was during the week. So I didn't realize it and did some heavy browsing. But overall this app is amazing and a must have..

[Q] Battery Life Expectancy?

I really hate to be that guy asking stupid battery questions, because we all know that battery stamina is subjective, but this is really hard for me to understand.
I am coming from the Note 3. My general weekday use with the Note 3 would get me 14-15 hours off the charger with 50% left by quitting time. I bluetooth stream music/podcasts for 8-9 hours a day. Pandora for maybe a couple hours on some days and average screen on time of 1.5 hours. I never had to do anything special in regards to battery life. Auto brightness and just regular use and it always lasted the day easy.
Today was my 2nd day with the HTC One Max and I managed to get just over 10 hours off the charger before it was completely depleted and shut off and it died in the middle of a work shift. Normal use for me, auto brightness, maybe 1-1.5 hours screen on time (estimation). Very depressing.
Battery use in settings looked pretty normal to me although I'm not seeing a place for actual screen on time? But my question is this, is this the kind of battery life you guys are seeing? Will it get better after a couple cycles? Based on the reviews I had read before purchasing the One Max, it was stated that the Max battery out lasted the Note 3 battery in testing so I wasn't even the least bit worried about it when making my purchase.
Not sure what my issue is but I won't be able to keep this device if I can't figure this out.

That's not normal. Factory reset it and don't load your apps in right away and see what you get. I have 50% remaining most nights when it goes on the charger.

I hadn't really had time to set anything up like I usually would. The only 2 apps I had installed were Pandora and PlayerPro but I'm more than happy to wipe and start from scratch. I've downloaded everything I need for S-OFF, recovery, ROMs etc, I was just waiting to make sure everything else was in order before I start tinkering. Just curious, are either of you guys running a custom ROM?

I've downloaded everything I need for S-OFF, recovery, ROMs etc, I was just waiting to make sure everything else was in order before I start tinkering. Just curious, are either of you guys running a custom ROM?

You don't need a custom ROM, this phone is perfect out of the box. Check with better battery stats what exactly is causing the issue. Could be Google play services.

This is the kind of usage I am seeing. Very light usage today, maybe an hour of bluetooth music and 0 phone calls, several texts (12-15). Not sure what this means in the overall picture. I also installed BBS but not sure what I am looking for, I just know my stamina is weak sauce. :crying: I'm not sure I understand why Android system is using 75% of my battery and only has 4 minutes CPU, 24 minutes keep awake and 4mb data sent.
This is what I'm getting. I have the power flip case, but it only adds 1/3rd more battery..
*note the screen on time*
You must have an issue with something keeping your phone awake.

Could you post your partial wake locks from better battery stats..

Oh bummer. I threw it on the charger as soon as I got home so there isn't really anything to see right now but I look forward to seeing how this looks tomorrow after work. Thanks.

There is definitely something wrong there. based on your shot, it looks like a verizon phone that doesnt have the power save.
Mines an international version my girlfriend got for me, Not rooted, S-On, completely stock out of the box, and this is my stats, mines based on moderate to heavy usage: (Note: the battery power saver turns on at 14% by itself) And my battery charges in 2 hours to 100%.

I haven't been able to figure it out yet. Most days its fine. Like Friday I listened to 4 hours straight of Pandora just because I wanted to see what would happen. Like usually I would stop it if I had to run errands or when I talk to people but I let it go for 4 solid hours. After bluetooth streaming 4 hours of Pandora and about 2 hours saved podcasts and 9:51 off the charger I still had 63% battery left. Thats really great results IMO. If I can get through and entire workday with 50% battery left I am thrilled. I think it was 1:13 screen on time or close. Not a lot of screen on time but that is a lot of Pandora use and that usually hits my battery the hardest.
But Tuesday earlier in the week I didn't listen to Pandora/Slacker at all, a little less than 2 hours bluetooth podcast,less than 2 hours screen on time and hit 38% by quitting time (about 10 hours off the charger). Every now and then there is a day like that where the battery just disappears even with super light use. I have GSAM installed and am trying to keep an eye on use but I always forget and plug it in when I get home (on days like Tuesday) or I plug it into the PC at some point to transfer files or photos and that reset the stats.
I tried that Snapdragon battery Guru and was really excited. The first day after it finished "learning" my routine I got through the whole day with 77% left but all day long I would stop getting texts and Gmails and the data connection would no longer work if I tried to open Facebook or Chrome. I would check status and mobile data is on, connected to the network, good signal but I couldn't get any data to work until I toggled airplane mode or rebooted the phone. SO I finally got frustrated with it, reset defaults and uninstalled it.
One thing I do notice is that I usually use 10-12% of my battery to wifi while I'm at work and the only wifi I use is when I am at home. If I turn the wifi off while I am at work I forget to turn it back on when I get home and now that I no longer have unlimited data that is a pretty big problem. I need to set an alarm or something that reminds me to turn it on/off everyday I guess.
