Battery Performance Experiment: Two ROMs vs. Stock

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.

Informal battery test

There are a lot of battery threads out there, but i wanted to try something new. I want to see how much our phones drain in real world situations. So here are the rules:
1. Use your phone normally for ten minutes.
2. Note your battery percent at the beginning and then at the end.
3. Post details about what you did, what ROM you're using, and the percent battery drain.
Hopefully we can compare our experiences and learn something.
I used my phone to surf a few websites, send one text, and use xda app. Started at 80% and ended at 77%. Using rcmix3d at 50% brightness.
I know there are tons of factors that affect battery drain, and I'm not trying to be scientific. I'm just curious how we all compare!

The only way you will get a decent idea is to test with others in your area as it will depend alot in signal strength. I would use more battery if I was bouncing between signals instead of having a steady connection.

Screen-on time is the only thing I ever look at. I've only managed to squeeze about 5h45m, out the sense-based gb ROM I've been using.
The phone does really well in standby on most if not all roms that have been flashed properly, don't have non-rom-related battery hogging app issues, and, as zelendel mentioned, signal issues.
It's this big fat screen that's obviously the biggest battery sucker.

My phone does great in standby as well, but seems to die quick when I'm actually using it. I've never had an issue with the phone dying on me though as I recharge every night. I think i had a little better battery life on miui than I'm getting now.
I know there are many many factors that go into battery performance, I'm just curious what other people actually get when using their phones.

I've gotten accustomed to putting my phone on the charger before bed as well. Mine pretty much will last the entire day... Off charger at ~8-9am, back on it at ~12am.
Averaging about 5 hrs screen on time with usually no voice calls of significant length, WiFi on, gps off, relatively stable signal.
I'm running Inspired Ace 1.0.1, and the 04.11_M2 radio. Seems I was getting a little better with the OTA radio, but signal fluctuated a lot more on that one, than with the 04.11_M2.
Edit: doesn't really use your testing procedure, just more of a general feeling, as there's so many other contributing factors...

Holly crap that's a heavy drain. I couldn't possibly use this phone with that type.of battery drain. Thanks to our great dews I managed a little over 7h screen on time. Could only accomplish that by reducing the screen brightness and UC to 768mhz. Stick speed and auto brightness I get about 6-6 1/2 screen on.

My battery will drain about 5% if I even just leave it sitting for ten minutes... I JUST rooted my Inspire and flashed the RCMix3D ROM, and it almost seems worse. Have background data, auto sync, wifi, gps, bluetooth, all that stuff shut off, too. I love this rom, but really want to find one that improves battery life!

You probably got a bad flash, or have something else running, as I mentioned in your recent thread.
Did you full wipe prior to flashing?
Try out gingerbeast, if you still have battery issues with that, after properly wiping prior to flashing of course, then it's hardware, as that ROM has produced some record-breaking battery life performance.

Mine has twice decided to randomly have days where it just drains like crazy. The battery is a lot warmer and just dies out in like 6 hours with very minimal usage. the majority of the time my battery is great but the last 2 days and then about a month ago it did this. No reason for it either, I have made no changes on my device.
Anybody seen this?

Yeah I did a full wipe before flashing. I'll be sure and try that out tomorrow, I really hope it helps. If the issue is hardware, should I contact HTC? After I believe you said my phone should still be under warranty, I called them, and indeed it is. The rep I had before must have been new or something. Thanks

From a full charge, on TPGB with wifi, gps, and sync on, and everything refreshed 3-4hrs, I lasted about 8 hours. I was using super accurate gps for 20 minute intervals or so, but it lasted the day I'd say. Some occasional web browsing.
Lucky for me my head unit on my car has a usb port. For this whole trip I left it off though.

Getting best battery per charge out of your skyrocket.

I am opening this thread to facilitate skyrocket users to share their experiences on getting most out of one charge.
I generally prefer something that shows percentage on top since the battery display does not provide detailed info.
I have tried few free aaps and finally found the best one. It is '2x battery' app. I used to loose 4 - 7% per hour in standby mode. With this app, It gives me 1-2% most in burn in hour. While writing this, I am 36% after 17 hours of regular use.

im at 11 hours and have 89% left using Juice Defender plus..

The only problem with JuiceDefender is that if you use messaging apps like Kik or WhatsApp, it will make it so that you don't receive the messages unless you have your phone active, making your phone pretty much useless.

I dont buy anything til I see proof of screen time and battery use screens.
Just got the phone yesterday, but I must say, coming from the epic 4g touch where I was getting 25 hours with 5 hours screen on time, it doesn't look promising.
But to be fair I haven't underclocked, undervolted and all the other tricks yet. Properly working sleep mode is essential.

I will try the 2x battery,

I use JuiceDefenderPro; custom profile
After 7 hours on battery, I am at 90%.
light calls, 1-bar of signal on 4gLTE, apps grab data every 15 minutes.

Anyone see results w/ underclocking?
I am using Antutu's CPU Master (Free), but my results have been inconclusive (sometimes uses less, sometimes uses more.. can't tell). I am considering getting the paid version of the app (or SetCPU or Android Overclock) to try the screen off profiles.

I use set CPU to underclock when the screen is off and when battery is low. In my experiences the savings are noticeable but not major.
With set CPU, juice defender, and a de-bloated rom I usually go to bed with around 30% battery remaining. That's about on par with my nexus one running cm7.

I haven't really had issues with the battery on my skyrocket. Then again, I'm not I'm an LTE area but you can pretty much expect bad battery life in an LTE area. Regardless, I have noticed something odd about the battery on my skyrocket, and maybe someone can confirm my observations here...my skyrocket tends to lose battery fairly constantly at first up to about the 80% mark then slows down the rate off loss of charge and I notice another huge slow down in drainage at the 30% mark. I've seen this repeatedly no matter what I do. In other words, screen on or off, I tend to see this happen. I'm not complaining as I think a 20 hour battery is great when using it heavily. And I kind of think of the slow drainage at the 30% as a nice perk. I'm running it stock so I can't chock it up to anythnng other than the phone. Any thoughts?

Why does everyone say this about LTE? It is simply not true. All LTE does is give you higher bandwidth with less delay. Wan't good battery life, run a custom ROM. I am running the ICS v4.1 and I must say it is much better than anything else I have tried. I keep 4sq, FB, twitter and gmail all running in the background along with BeWeather updating every hour.

Everyone says that about LTE because (from what I've read) running LTE requires more power due to several reasons. I did a quick search and sprint may be a great indication of proof of the power consumption of "4g" from what I've read their phones disengage wimax when not in use in order to conserve energy. If LTE is faster and operates at higher frequencies (if I'm not mistaken) then it should require more energy. I could go outside the box and come up with some equations that relate frequency to energy (they exist) but I will admit I don't know if they can be applied to the circuitry in phones though I don't see why it wouldn't as the theory is sound. In any case, yes running a custom rom will do wonders for battery but some of us haven't taken that plunge yet. As it is, my stock skyrocket is doing great for me lasting 20 hours. Im out of the house at 6am and usually don't get home till 8 at night. It makes it through that with ease. I'm happy with that. Bring on the LTE, I'll cross that battery consumption bridge when we get there.

Since you know you don't get a signal inside your school, you might as well turn off mobile data or even just airplane mode it while you're in there.

I agree, turn off the radio so you don't waste the battery. Maybe you can use something like Tasker to do it for you only when in class.

Tasker is very difficult to use. I have tried and failed. haha. but i found an app called autopilot that will basically do the same thing youre looking for. it will check for signal strength and enable airplane mode if its low. then recheck in intervals to see if it should turn airplane mode off.

Yeah. Idk why I dont already do that. Lol. But I do seem to get a little bit worse battery when using it. Not too bad but not like before

The cell standby is calculated incorrectly so don't worry about that. It's not really using up any battery.
For the exception where it's trying to locate the towers.
Anyways, i'm on CM10 latest night build and i'm getting awesome battery life, along with the VRL15 radio and RPM

I have "my profiles lite" it lets you set times you can have the airplane mode activate so if you have brakes at certain times it will come on at that time

I have used the app called NoBars, which puts the phone in airplane mode when it loses signal for a set amount of time. It then retries after another set amount of time. Sure, you don't restore the connection immediately after getting back to a signal, but it works pretty well overall.

its easy to manipulate your battery screen to be on for many hours.
your screen on time is a better indicator of how your battery is performing.
all is dependent on settings o course though.

ya went back to synergy ics rom and its night and day my battery last forever on this ics rom with lean kernel at 1.7ghz compared to stock speeds on jb and this ics rom is SO smooth has google now so im not to worried about jb till they get battery life straightened out.

Loving CR4 and the battery.
It was asked how the battery is on CleanRom4... it's doing great! I don't have specific but let me say I use my phone all day for surfing XDA forums as well as standard apps/mms. Talk about 2 hours total daily for work. Even throw in some Netflix and I don't charge it except for every other day.
I would say that's great battery life.

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.

Same here. I'm in and out of LTE all day, so I just leave it on hsdpa unless I am in a solid area and tethering. Made a massive difference in my battery life.

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?
Thanks.
