So, I recently cancelled AT&T but I wanted to make a couple of last remarks on a battery issue, so as to (hopefully) better inform the devs. Up front, I will say that the reception at my house is terrible (hence my cancellation). As such, I expect somewhat poor battery performance. I have run nearly every version of Cognition, tried the AOSP project, and most recently run Perception. After using these, I was left with the impression that the battery performance in all of these has been disappointing.
Having received my new phone and with my old service not yet deactivated completely, I decided to try a more formal test. I used the following test protocols in order to ensure a fair and accurate comparison was conducted:
1) The phone was positioned for the worst possible reception in my house. It was only moved to change ROMs and was returned to the approximate location it was previously in.
2) Each ROM was flashed at 100% battery, with SIM and SD Cards removed.
3) A battery recalibration was performed after each flash, as detailed in the Cognition thread (Charge to full, turn off, charge to full, turn on, use for 2 minutes, charge to full, delete battery stats). Following this I did one more complete discharge and recharge to ensure the statistics would reconfigure with the calibrated battery.
4) GPS and Bluetooth were turned off; WiFi remained on and connected through all test runs.
I loaded Cognition version 2.3b6 and then Perception build 3, both of which performed approximately the same. Leaving my phone on standby and with only very light use (0 answered calls and no internet surfing or messaging), I could get no more than 15 hours of battery power before it died. Following this, I restored my phone to the stock JH7 update and, as of now, my phone is at 54% after 2d 19h 25m of use.
I know many people have been flamed for daring to suggest that the ROM has something to do with the battery draining abnormally, but I did this test as objectively as I could so that the community of developers can use the information to improve on this issue. In my opinion, this test suggests that something in the custom ROMs is causing an excessive battery drain. While this may not be happening on everyone's phones, it is most definitely happening on two of my Captivates. Hope this helps and good luck! I am off to Droid X Land! Suppose I'll use my working GPS to get there! (Sorry, couldn't resist... too soon?)
Edited for grammar and clarity
Poor signal is the biggest battery drain. Especially in 3g areas. I have had phones on VZW and ATT (different times and locations) where my battery would not last 8 hours.
Another test to show it is not the ROM or OS is to put the phone in airplane mode and observe almost 0% battery drain overnight.
But since these custom ROMs are built off beta releases, I am not surprised by your results.

I noticed the same thing a while ago and am just hoping there is some issues with the fact that these roms are being developed on leaked builds without the source code.
The key thing to notice in the attached screen shot is the near constant 1-3% cpu activity when the phone is not being used. On JH7 I could leave my phone on over night and only lose ~3% battery. Currently on Perception build 4 I lose ~20-25% overnight. On Cognition 2.3b3 I lost about the same.
I get about 16 hours on my captivate with light to moderate use on the froyo leak.
on Perception and Cog (latest builds) I was getting about 9-10 hours with very light use.
I need another battery

I doubt the battery is your problem. As my test suggests, I am pretty confident that if you were to restore to stock, you would find your battery risen from the dead.
I can vouch for the OP about battery life. Battery life on JH7 is WAAAAYY better than any custom 2.2 ROM. I am running stock JH7 with Atimns v1.10 Voodoo kernel. Beats the pants off of the Cognition 2.3b6 ROM I was using battery-wise. In my experience, all of the Froyo based ROMs have battery issues. :-(
I just searched up a little bit more and found that the sensor is using a lot of juice because of a bug in the picture gallery app included in all froyo roms/leaks. I checked my sensor use and sure enough it was at 6 hours non stop. uninstalled using root explorer installed the Gallery3D.apk found on this site and now the use is at 2 seconds. I hope this was the cause. Also, is the android system supposed to be using so much of the sensor? My phone has been on for 11 minutes (reboot) and the battery history in *#*#4696#*#* says its been on for exactly the same amount of time...
sorry for the thread jack!

The issue with the gallery using the sensor has been known for some time. If you our the rom dev did not change out the apk, you should.
Well I changed it and my battery has been going great! Heavy use with 5% decrease per hour since I replaced it.

To be fair...the custom ROMs I have tried each had WiFi set to always on. The stock ROMS from had is set to only be on when the screen was on. Depending on the availability of a WiFi AP, this can make a huge difference. Looking for a WiFi AP to connect to is costly.

In my case, this was not the difference for me. I always had my WiFi always on, even with the screen off. I turned it off manually if I know I am going to be some where WiFi is not available. The battery drain is definitely somewhere else....but these are leaked Froyo ROMs for a reason.

It depends. If there is a lot of data transfers going on and WiFi is off with the screen, these transfers will take place over 3G, which in more cases is not as power efficient as WiFi, all else being equal.
I'd say, WiFi always on is better, in my experience anyway. Mileage may vary.

For me personally I get terrible battery life when wifi is on. Everyone on here seems to say that leaving wifi on saves battery but this has never been the case with any device I've ever owned . And I'm talking about when I'm sitting home in an area with good wifi reception too.
I can't figure my battery out at all. On the weekends if I stay home and keep wifi on my battery will be on for 20 hours and still have 65% left. Once I leave home and I'm using 3G I can only get about 5 hours. I've lost 20% or more per hour without even touching my phone.
Another weird thing is under battery usage and "cell standby", it always shows time without signal at 50%. Never more and never less, always 50% exactly. Any ideas?

Wish I had the answer for this too. Mine says the same exact thing. Always 50% yet I always have signal where I am. I'm hoping it's some sort of miscalculation and not a major bug where network connections are being dropped constantly and not being shown.
I get three+ days with my phone...
Sent using smoke signals.
Man, I thought I was in my own boat. Same exact symptoms across Cognition, Perception, Axura, you name it. Something weird though is that the first day is always great on battery, then after a night's charge it goes back to the 12 hr max per day (moderate usage). On stock it definitely lasts a lot longer. can't wait for an official froyo release... especially now that I have to use Good Messaging, another huge battery hog.
Flashed CleanROM V and did a battery calibration running it down to 0% a couple times but getting terrible battery life still. I work in a concrete warehouse all day so the signal is pretty weak. Any suggestions and maximizing my battery?
Perhaps try turning off wifi if you've not got a signal & try kicking the phone back to 3g.

The screen on to awake ratios should roughly be similar but it looks different in this case, install BetterBatteryStats to check out wakelocks.
Also, your mobile signal appears to be very weak and dropping out.
PS. Wiping battery stats does nothing
Wow, you should be getting easily double that if not triple the usage.
First thing, if you are in a area where wifi is available, you can disable mobile data(3g/4g) completely. if not, then leave wifi turned off and use 3g, i dont use 4g lte unless im downloading something BIG.
Secondly, if you want to, you can close the apps via task switcher every few hrs, but not mandoatory.
Lastly, update your device to the latest version 2.20 or 2.40. I got easily 15-20% increase when i updated from 1.85 to 2.20.
Also you can leave your screen to auto brightness, which helps by itself, i used to change it myself but i realized auto is better since it changes it instantly depending on the situation.
Doing this gets my phone to average 30hrs standby with about 3hrs screen on time. Heck, few times when i used wifi mostly and data turned off majority of the time, i got 5+ hrs screen on time within about 24hrs usage.

That's what I'm saying! For such a great phone I should be able to use it more at least I'll look into disabling 4g. LTE just got turned on in my area and i'm soaking in the super fast speeds Probably not worth the sacrifice in battery if that's the case though.

Hey not sure if im even putting this in the right thread but im very new to rom and kernel flashing etc
Im running CleanRom 5.0 and Beastmode 4.3 Kernel
My battery life right now is 30% after 8 hours...what am i doing wrong both the rom and kernel have allegedly good battery life...i recently flashed both like 2 days ago...am i supposed to let the kernel and rom calibrate etc before i freak out about the poor battery?
My screen is using abt 60%
voice 20%
standby 5
whats app 4% phone idle 4%...not sure what other info to provide but can anyone help me make modifications for better battery life
im using kernel tuner i tried governor: badass, wheatley, intellidemand..my screen brightness is veryy low i took it off auto because i felt it was sucking it even faster. I dont think im overclocking...random apps like youtube, facebook etc are running in the background is this a huge problem?
someone pls help!
thanks
What is your screen on time?
60% brightness isnt "low" by any means, I usually leave mine on 40%. You made a good choice to take the phone off auto brightness.
Personally I got really bad battery life with beastmode. I now run flar2's experimental 1.5 GHz kernel and couldn't be happier.
Radios also have a significant impact on battery life. The 2.29 radio + ril has worked best for me with battery life.

Yeah you have to keep in mind how you're using your phone. If your screen is on for a lot of taht 8 hours, that's a decent run.

Think he means screen is using 60% on the battery usage stats, not screen brightness.
60% is fairly high. I think he just has the screen on a lot. Brightness may also be a factor. Only about 4-5 hours if screen-on time is to be expected on low brightness.

Battery life
Hey guys, I've recently bought a AT&T HTC One X. This is my first smartphone, and it is fully stocked, locked bootloader and no root, android 4.0.4 and software version 2.20.502.7, really like the phone. However, I am not really impressed with the battery life. I would usually charge it over night for around 8 hours, take it off in the morning at around 08:00, take it to school, casually check facebook/gmail, maybe watch one or two videos and by the time I get home at around 15:30, the battery would be at around 15%. I was wondering whether this is normal and if there is any point of my rooting the device and flashing any custom roms?
I have disabled all the AT&T bloatware, decreased my screen brightness to around 25%, no live wallpapers, disabled auto syncing, wifi and mobile data mobile switched on only when I use it, only have a weather/clock widget and a couple of games. So I have been researching about rooting and customer roms for about a month now, and found out that some members have amazing battery life times with Cleanroms and custom kernels, so I was wondering whether the latest 5.1 Cleanrom with a Beastmode kernel 4.4 would cause any damage to my phone and whether any of you guys are using it?
Thanks for your time!

Are you using LTE? I found that my battery would drain very quickly when set to use LTE, even if I'm on wifi. I guess the LTE towers were further away or something because my signal would drop really low. I leave my phone on 4g for the most part now, only switching to LTE when I really need it, and I can get two days of battery with light usage. I've only recently flashed CleanROM so I would expect it to get better, but it's too early to tell. I've only got 22 minutes of screen time, but my phone has been on for 9 hours and it's at 85%.

Wow, that sounds good, even with that much screen time the standby is much better than on my device. Sorry I forgot to mention, I live in the UK and LTE or 4G is only available in major cities. However, my phone is AT&T and is sim-unlocked, and I get the '4G' mark on the top of the screen, therefore I think it might be the HSPA+ that is available in my area, which I rarely use anyway.
Is it the stock kernel that you have flashed with the rom?
Thanks.

Just because that person got a particular battery life by toggling off LTE, don't assume that you will get the same results. Battery life often tends to be very reception and location specific.
I leave LTE on 24/7 (as well as WiFi, and brightness on 40%), and can get close to 48 hours on a charge with low usage.
Also, bear in mind that you can't toggle LTE off on AT&T stock ROMs.

That's correct, on stock AT&T ROMs, the "4G" icon means HSPA+. If its on LTE, it will say "4G LTE".
My guess is that you are just having reception issues. Flashing ROMs and kernels may get you slight improvements in battery. But don't expect it to make a huge difference, or you will likely be disappointed. A different radio may also help.

Thank you, I will have this in mind. I was wondering whether it was due to reception or was it just the batter malfunctioning. In your opinion, would it be better to wait for the Jelly Bean update and see whether the battery life improves?

Hello all.
I'm getting the feeling I'm not exactly getting the battery life I should be getting with this phone.
I had another LG G2 before the one I currently have now. I swapped it out during the 14-day return period. That one had screen flickering (which I now know that is due to content adaptive contrast etc.) and [aesthetic] the day after actually getting the phone, getting a scratch on it. However, with that day of having the phone, I felt as if I got better battery life compared to this one. That phone had Carrier IQ running on it when I didn't know anything about it. I only knew about Carrier IQ's problems once I had the current G2.
I'll post my battery results at the end of the current day from GSam, but attached are my current battery results at the given moment.
I have been using it actively since 6AM or so.
Screen at 30% brightness, WiFi on all the time. I have made the effort to disable all AT&T bloat and I have stopped Carrier IQ, LG Intelligent Agent or whatever its called and SmartCard.
I'm unrooted, totally stock (what comes out of the box). I have KNOCK ON disabled along with SlideAway if that helps.
No gaming has ever been had on this phone. Just Facebook, Messenger, and Chrome for browsing the web. I also listen to Google Play Music.
I talked on the phone with AT&T on Wednesday and they suggested a factory reset, and if it didn't fix it, to warranty the phone out...which would result in a refurbished phone and I'm kinda not okay with that because I paid for a new phone and I don't like having to get a refurbished one that is supposed to resolve my issue somehow. That's just me though.
Last night, I charged up to full while the phone was shut off. Factory reset my G2 and I still get this feeling I'm not really getting proper battery life.
Are these the type of results of what I should be getting? Not representative of a day actually out and about (which will be Monday as I have school then), rather at home. I will give stats of the end of the day use of Monday...at the end of Monday. Thanks in advance, and hopefully I have given enough info AND stats. I'm still sorta new to XDA.
I'm sorry, but you have 3 hours of screen on time and only used 40% of your battery. I think that is pretty darn good. I wouldn't be concerned with this. You are making me wonder about my device.. I have 62% left and only 1.5 hours screen time

Ahh okay. The G2 is a nice phone in terms of performance, functionality etc. Battery life was supposed to be a major feature of this phone because of the optimization and battery size...so that's why I'm concerned when others are seeming to get much better results.
If you don't mind me asking, why are they giving you a One for warranty exchange? I personally wanted a One before this phone, but it was cheaper, had better features, specs and battery life etc.
EDIT: just noticed you stated the purple camera issue. Sorry..I didn't know that was a problem with it though. Last I heard of such was with the iPhone 5's new sapphire lens...but that was fixed through a software update (somehow).

Yea the One is a great phone - I'm still not sure what I want to do yet! The problem is with most of the first months the phone was built. My wife has the mini and it was built in September- she doesn't have the purple issue. I could just send the One into HTC and have them fix the camera.. I am a little disappointed with the G2 shutter speed with flash on tho; but I am pretty sure this is fixable with a software update.
Is Carrier IQ really draining the battery? Is that why my idle battery life is terrible?

The G2 takes a bit of time in low light (if thats what you're getting at) etc. because its trying to suck as much light as it can. It does a great job because it takes its time...its just understandable why its doing that. That's why its quick and speedy in proper light (which isn't too demanding). I'd rather have proper exposure at the expense of time.
Yes, carrier IQ is exactly why. Do a bit of searching around on Carrier IQ on the AT&T G2...its the only carrier variant of the phone affected by it. It causes major wakelock and demands GPS even when you have done everything to disable location services. I also recommend, while you're at it if you haven't, to disable WiFi and mobile network connection under location access in settings.

It causes major wakelock and demands GPS even when you have done everything to disable location services. I also recommend, while you're at it if you haven't, to disable WiFi and mobile network connection under location access in settings.

I agree that I'd rather have a better picture than a faster snap When the lighting is good, the shutter speed is great - I posted a couple comparison shots on another thread about the One vs the G2.
As far as the CIQ - I disable IQ in Android system settings - as well as the wifi and mobile network location settings. Will see how this affects battery life.
I still think you are getting great battery life compared to mine - I'm down to 42% battery with 2hrs screen time.. I'm using Lux for brightness and it keeps the screen pretty dim compared to the built in auto brightness logic LG uses.
uninstall the maps update and disable the auto update for itband ur batteryvwill be good i just didbthat last night and my phone has been on forv24 hrs and im still at 69% with 4 hrs screen tine

I'll check out Lux.
Also, see how your battery improves after disabling Carrier IQ etc. then we will compare and see who has better battery life. You should definitely notice a personal difference. You may not think there is something wrong with your phone anymore.

Ahh okay. I tried a similar thing where I uninstalled updates and reinstalled... Cuz I read that somewhere. But now I'm doing this. Will report back if I see any difference.

I can't seem to disable ciq using system tuner - the check boxes are all grayed out-- any tips? do I need the pro version?

I just do what you did earlier - go into Apps > disable IQ Agent running under Android system, go back, click Android system again and stop the actual service...and do that every time I reboot the device.
You can totally remove it I believe with root, but I have been aiming to refrain from rooting until my 1 year warranty with this phone is up
I average %5 per hour.

What type of usage? With WiFi, over data, brightness setting..etc?

oh okay. I read people use system tuner app, but I'm not sure how as the check boxes for the running services are all grayed out so it isn't possible to uncheck them. unless a rooted phone is needed, I don't know, I can't find specific information on it.

D800, stock, full brightness (not auto), Wifi when indoors, 4G LTE when outdoors with wifi on, blutooth on all the time, mix usage.
These were taken on different days. I always have wifi, 4G LTE and blutooth on.
I notice a drop when I have a lot of data transfer or a lot of screen time, but overall it never made me complain, I only complained to myself when I pushed it to limit because I got spoiled by good battery life and I stopped the habit of plugging it all the time. Now when I pick up, it has 30% and it can still last few hours easily, whereas before %30 meant "oh ohhhhh"..

Okay, yeah. Nice stats. I'll see how things go so far with the past suggestion of Maps etc. but yeah I totally agree with 30% thing...its weird thinking that too. But I have adjusted...kinda.
Just a quick note on standby battery life - I used the phone until it completely shut off last night around 7pm or so.. at 10pm it was fully charged, so I pulled it off the charger. It is now 8AM, and the phone is still at 100%!! I did not get any texts/emails overnight, I left WiFi/4G on.. GPS stayed on along with Wifi/mobile network locations on.
When the phone shut off and I charged it, upon reboot, I did go into location settings and disable IQAgent.
I also removed some apps (Lux/GSAM), and reverted Maps to previous version. Not really sure if Lux or GSAM are a culprit or not.. I used GSAM on my One only because HTC removed the battery stats - LG has this in the battery info. Although GSAM is nice, it isn't really necessary unless drain is outrageous.
Let's see what today brings for battery life!

I know for many, the standby of the phone is said to be a killer. I might just remove GSam too. I tried out Lux BTW and I was really shocked just how dim the display got where it was even hard to see in a dark room
So far I haven't noticed any change in battery life while consistently using the phone. However I will say when I rebooted real quick last night, I forgot to take care of Carrier IQ and noticed that the battery was dropping incredibly fast. I then remembered I forgot to disable it, and then all was well. Just shows how much of a difference it makes!
I have always used Better Battery Stats to monitor battery life and wakelocks, etc, but without root it's stats are limited. It does show how much time the phone "sleeps", and so far my phone is "awake" 100% of the time. I initially enabled almost everything but am wondering if everyone is experiencing the same?
I'm having cell standby battery drain
Yep same. Phone refuses to sleep. Probably the cause of battery drain. Hoping they release some sort of update to fix that.

I'm sorry... I'm posting this from memory... But I think I saw somewhere that this is caused by the voice over Wi-Fi. In your phone settings turn off calls over Wi-Fi or something like that.

I had heard that as well in the main S6 forum but I don't see a wifi calling option on the vzw variant. Am I missing that or is it only present on the international version?

I think it's called VoLTE or something. I'm still waiting on my 128gb version so I can't check for you.

VoLTE is Verizon's HD voice. Don't know how that would cause cell standby issue. I'm having issue as well and it sucks.

Right, its not enabled by default either so I'd think that rules it out as a culprit.
Something is certainly going on though to have these high cell standby times. May require an update from the powers that be to fix this. Aside from disabling everything on the phone which isn't happening.
But if its a big that's prevalent in the tmobile version as well, it may very well be the same bug depending on how Verizon chopped the feature from the software.

Yeah it seems likely it's an issue that will be fixed across the board if it does get fixed. I'm hoping it happens in the first 14 days while I'm in trial, cuz otherwise I'm not sure if I'll keep it or not. Strange thing is some people seem way less affected though. And that's coming from a guy that typically has full or near full bars at both work and home so I'm certainly not in a fringe area by any means. Idk?
I have full bars all the time data disabled and I still get it
I had cell standby issues all weekend. Last night I turned off VoLTE ("Advanced Calling") on mine, and turned off cell data altogether while at home on Wifi. I was going to test it all day today like that, but this morning I thought, "No, this is dumb, if I can't use VoLTE the phone is worthless as I need simultaneous voice/data". So I turned it all back on, and Cell Standby isn't even on my battery life screen now. And it's had plenty of time to show up... Right now I'm at 50% battery life, 1.5 hours SOT, and 6 hours on battery total. My problem is Google Play Services is killing me - also a new problem since yesterday, and I have no idea what's behind it.
Cell standby is eating my lunch (and battery), too. 20% of my battery utilization, and my phone is running hot. The latter makes me think it's some app causing both the consumption and the heat, but darned if I know why.

It seems there are two things that might fix that - turning off wifi completely, and wiping cache (boot into recovery [vol-up + home + power]). Have you tried either of those yet?

No wifi isn't really an option, so I've wiped cache. I'll report back. Thanks!
Reporting back: no difference. This is a bug, as reported many places. Might be a deal-breaker for me, coupled with the prospect of no root. Might have to swap to the Motorola device.
