110 hours on a single charge!

[Edit:] I've changed the title to reflect 110 hours. The original title and body of post reflected 100 hours, but since then I've added two more screenshots at the end of this post to show 110 hours (4 days 14 hours), and I added a (absolutely horrible) video to show that I'm running a standard battery (not an extended battery). NOTE: When I say the video is horrible, I mean it came out sideways, and is barely readable, and is a ridiculous 29MB in size. But the two added screenshots back up the readings and statements in the video. What follows below is my original post.[/edit]
Hey all, this is probably not any real record around here, but I wanted everyone to know I've just passed the 100 hour mark, running 100% uptime since the last battery charge!

Notably, for at lease one-third of the total time, the phone was in an area of poor (or no) signal strength.
For this test, I had wi-fi, mobile internet and GPS all disabled...the only active radio enabled was the telephone voice radio, which was always enabled. I could (and did) recieve calls during the entire time (though I kept the conversations very short).
Here's how I've got my phone set up:
nfinitefx45's stock 2.1 ROM and Darch's Infinitefx_vUV_710 kernel, without freemem tweak (it's not the new vUV2 kernel).
SetCPU, set to 614mhz max and 19mhz min (245 max & 19 min sleep mode), with additional fine-tuning.
AutoKiller, with values I set individually for the different fields (didn't use any of the pre-set options...my settings are probably pretty close to "Agressive", except for the Content Provider value).
I use Advanced Task Killer to kill any apps that I'm no longer using, and I always have. But I've got it set to ignore SetCPU (because I've got a screen-off profile defined and enabled), and also set up to ignore AutoKiller (but I'm not sure if that's really necessary).
Notice the amount of time the phone spends at the different cpu speeds:
Because of the way I've got SetCPU set up, even though I have max speed set to 614mhz my phone rarely runs at that speed...the Powersave bias is set to 125, so most of the time that I'm demanding any real-time performance from my phone, it's actually only running at 537mhz. Likewise, even though screen-off max speed is 245mhz, most of the actual activity in that mode is at 122mhz or 160mhz, again due to the the Powersave bias setting of 125.
Also note that a great deal of time is spent at 19mhz, during both screen off and screen on states. Even so, I experience no noticeable lag, because the phone immediately jumps up to a faster speed as soon as any need arises (such as swiping between screens).
In case you're wondering why some cpu time is showing at 710mhz even though I have the max speed set to 614mhz, remember that I'm running the 710mhz kernel, so while the phone is booting it's running at 710mhz.
I must admit to being miserly in the use of my phone during this test, even though I burned a couple of percent battery downloading the ShootMe screenshot app last night (just so I could provide these pics). And I used EStrongs File Explorer to send the screenshots to my computer over the wi-fi so I wouldn't have to plug in the USB cable.
One more thing...I'm not done yet! I'm going to get another screenshot after my Saturday afternoon nap...hopefully I can get 110 hours out of a single charge.
Cheers!
[Edit:] Here are the two added screenshots that show 110 hours (4 days 14 hours), and the horrible video I shot to back up the fact that I'm using a standard battery.[/edit]

That's a lot of time on one charge. But as you said, not using it much. I think the 2+ hours of awake time is telling.

The point of my post was to show how I've set up my phone to conserve battery when the phone isn't actually busy doing something.
Many forum members, in many different threads, have stated that they burn through battery at a rather disappointing rate even when they're trying to conserve juice. Darch went to the trouble of building up a batch of UV kernels to alleviate as much of that problem as he could (thanks Darch!). In large part, my post was basically explaining how I've taken advantage of that kernel, and nfinity's ROM (thanks to you too, nfinityfx45!), and careful tailoring of system and app settings to set my phone up so that battery drain during periods of inactivity is minimized.
Taken as a whole, the results indicate that my average battery drain is less than 1% per hour. In light of the fact that one third of that total time was spent trying to stay connected to a poor signal, I'm quite confident in stating that during times of good signal my bettery drain is significantly less than 1% per hour.
How many people can say they're realizing that kind of battery conservation with their Hero on an everyday basis? I've gone to the trouble of determining what works and what doesn't in terms of conserving battery, and reported on the setup and the results. That's all.
Another point that could probably be taken from the data is that, all other things being equal, I would probably get better battery life doing the same everyday stuff with my phone than the regular Joe who hasn't taken similar measures to minimize unnecessary battery drain on his device.
The bragging was just icing on the cake!
Edit: So sorry, I meant to also thank urushiol for the UV kernel!

This is pretty sick! Are you also using an extended battery?

i thought that auto killer is bad if you use an OC kernel?
thats hella right though
i've been waitin for someone to post somethin like this so i can maybe get 24 hours with moderate usage

Nope, I'm using the original battery.
The phone just now beeped at me, and the warning screen says I have no more than 9% battery remaining. In two more hours I'll have 110 hours on the battery. At that time I'll use my wife's Hero to take a video of my phone's battery usage screen, and then I'll pull the battery cover off of my phone in the video so you can see I'm running a stock battery...it says "HTC Innovations" on it.
I'll post the video after that.

AutoKiller is only bad if you're using one of the kernels with the built-in free mem tweaks.
That's why I'm not using a kernel with free mem tweaks...that way I'm free to use AutoKiller and set it up like I want. And I want a custom setup, not one of the preset offerings that comes with the app. I want to use agressive values for most of the settings, but I want to set the kill value for Content Provider to a low number, because if I use the preset value for Content Provider in the Agressive setting, it will kill the GPS antenna input to my tracking app when I'm on my mountain bike, because the phone's in my jersey pocket with the screen turned off...in such a situation AutoKiller presumes the content provider to be a background app and shuts it down if the kill value is set to anything but low...sheesh!

Okay, I've edited my original post to include a HORRIBLE video showing the standard battery being used, and I added two more screenshots showing 110 nonstop hours on a single charge.
So I'm going to finally put this project behind me now, and get back to the truly enjoyable business of actually using my phone again!
And a HUGE thanks to all the devs who've made it possible to get such incredible performance out of our phones!
If anyone cares to know why I decided to use any of the settings that I did, just ask and I'll be glad to talk to you about it.
Cheers, and a good night to all!

wow thanks for the info on autokiller
i can actually use it again! whoo!

Battery after 2.3.4 and rooting

So I've rooted my first android phone yesterday!
I've noticed the battery is a bit better.
My battery is down to 67% after 1 hour and 23 mintues of display turned on. I've barely installed anything on the phone.
Is this okay? Should it be better?
Another thing: is there a way to "underclock" or reduce the voltage and save battery like that?
I want to get as much out of the battery as possible.
Thank you

33% drain in that time is pretty poor, I'd expect no more than 10%, but ideally less.

The phone automatically underclocks when youre not using the phone. I had system monitor installed and noticed that when im not doing anything on the phone, the processor goes to 200mhz, and as soon as i click around it jumps to 500 800 1200mhz depending on use.
As for your battery issue, i noticed some apps keep your processor busy at 1200, and then your battery drains even with the screen off. And no thats not normal, in one hour it should at the most go down to 90% on idle. The battery is actually impressive.
And sometimes, when you're on 3g networks and the signals are low, your phone will still drain the battery. And you will notice the back of the phone heating up, oth from running the processor at 1200mhz and using 3g

Rooting has nothing to do with battery .
jje

My friend tell me root will cause battery run out faster, is that true?

No root is gaining administrators rights to a lower level of the OS .
jje

It's not 1:26 of idle, it's of screen time use.
I've got in my funning services stuff like, email, social hub, music, google+, juicedefender, google maps. Could any of these be draining my battery?
How can I keep some of these apps from not being in my running apps?
For instance, when I force close the google maps, it turn back on after a few seconds.

Google maps and gmail app never bugged me, but i did have issues with social hub and email. Use to drain my battery, so i just signed out because there was no way to stop the background services. Besides that i always have gmaps, gmail, gtalk, go chat for Facebook, Facebook app, whatsapp running in the background and no issues.

Do you set the brightness to full often?
Sent from my GT-I9100 using XDA App

Set automatic at the screen menu.

No, my brightness is almost always on the lowest setting. I turn it on fully only when I am in direct sunlight and need to use the phone for browsing etc (which doesn't happen often, mostly calls which I can do with minimum brightness).

I dont really know where the problem is, but it doesn't sound normal, the timing you say you are getting. Try to keep a black back ground and dark themes ( because in Amoled displays although low power consumption they use more energy to display white and colors rather tha black). And ley your phone turn off with low battery and charge it to full without disconnecting, to complete a cycle for better efficiency

so 1.5 hrs for 1/3rd battery usage?
This means you'll get about 4-4.5 hrs of screen usage (assuming normal drainage during screen-offs). This is normal I would say.
On my undervolted phone, I usually get about 5 hours of display time + about 10-12 hours of screen-off time which carries me through the day quite easily.
You can Undervolt your phone using Tegrak's app. More on that here.

Also, you can freeze system apps etc that you don't use by checking this list (using Titanium Backup). (Credit to shanume)

What's your phone carrier?
If your are in Japan, You need to configure build.prop.
If your not in JP, I don't know.. Try flight mode. or running without SIM.
so that you can check if the issue related with signal or not. at least...
Sent from my HTC Desire using XDA App

I'm not from Japan, but you guys make it sound like something is wrong.
Is there an app that can monitor the usage so I can post results somehow?
Maybe monitor it for all running apps etc?
I did this little test yesterday:
I played a video on my phone (from the SD card) for 20 min with no sound. It took down around 4% of the battery. It was a 720p (1.4GB for 50 min).
Is that normal?
Edit: Just tested it again: 30 min of 720p video, with max volume took down from 25% to 17% (so 8% battery for 30 min 720p video from SD card).

Again - both 4% for 20 mins and 8% for 30 mins sound normal. You can post these numbers on the Litening Rom thread (quick link in my signature) and other users can confirm.

this is poor... not sure what the hell original ROM doing with you.. in case you dont mind you might give it a shot to try litening or criskelo ROM..

[Test] Battery Draining

Ok, I've been thinking about this for a while now so I'm going to make a test to decide if I really need a battery saver. I'm making this test for myself purely but I thought someone might wanted to see the results as well so here we go.
The gear:
Samsung Galaxy S2, non-rooted
2000 mah Samsung battery
The competitors
Phone on its own
JuiceDefender Ultimate
GreenPower Free
The settings
Prefer Wifi over data
Connect every 30 min to sync
No night settings (to be fair against the others)
Screen brightness: Auto
I know the battery savers are made to save battery when not using your phone so the screen will be locked the phone only used for a small amount of time between chargings.
The phone is unplugged at 100% and I will continue down to 30% before charging again. I will only be testing each one once, as of now at least.
We'll see how it goes over the next days so feel free to ask questions and such.

Many people I know with an S2 use battery saving apps but i really see no point in them, when we used to compare our stock phones running the same stock ROM there was minimal battery difference. Haptic feedback will be off or on? That makes a big difference.
You should put in a custom ROM to see how much better it is compared to stock.
i look forward to seeing the results of this test though

If I got it correctly haptic feedback is phone vibration on touch, right? That's off at least, never liked it. I'd like to put a custom ROM but I don't want to root the phone, yet.. Maybe in a few months or a year...
I will be updating this as we go along. At the moment we are at 96% with 3 hours of sleep time and only a few minutes of screen time.

Ermm, can I ask does task killer drain your battery? Sorry if I ask the wrong question.

task killer will drain battery if the programs you closed restarts, use advance task killer and ignore those that do,you may need it for those apps that didnt close properly
im interested in your trial, juice defender service was failing to run on my s2, it ended up eating my battery restarting the service.
im looking to save power as i lose 15% over night with flight mode while i hear people lose 1,2%

Yes Android is a bit different than computer OS. To start an app drains more battery than just pushing the "back"-button and let it be in stand by so don't use task killers.
Yea I have had trouble some times with the battery saver draining quite a lot over the night but usually it has been because I had a mail as a widget with push-notification so the battery saver wouldn't disable internet but almost push all my other accounts as well. That was my solution at least. We'll see how this goes.
4h in 93% battery
15 min scrren time

A little update. You see where we are.

And does anyone know what can have caused this? This is a picture from a few days ago. It has happened maybe 10 times over the last 2 months. Simply the phone gets hot and the only way to unlock the screen is to remove the battery, refit it and then start it. And then it shows this massive drain.

Okay we got 1 day 13 hours down to 30% with 30 min of screen time. Next up is the Juice Defender Ultimate with night settings off.

An update for you all. As you can see JuiceDefender has already passed the "vanilla" time.

I had an odd problem. Sometime during night, the battery suddelny decided to drain at much faster rate and it took it only 6 hours or so to drain from 75% to 15%. I checked with BetterBatteryStats but there seems to be no app that has kept it awake. Anyway, I can't continue with this test spimply because I don't have time for reruns.
What I can say in previous experience:
Vanilla
Great that as soon as a message comes in you get notified immediately.
Unfortunately that's because wifi or data is kept on all the time, draining battery.
JuiceDefender
Usually gives my phone 3-4 days of battery.
It does take some time (up to 15 sec or so) when you unlock the screen to connect and that can be annoying if you are in a hurry.
When I have night settings on to set phone in no vibration, no sound but also have different night setting time for weekends the phone vibrates once at midnight between weekdays and what JuiceDefender recognizes as weekend.
Sometimes it doesn't feel like the apps are updating even though settings are set to allow "dumb apps" to update as well as plenty of time to do so.
GreenPower
I have only had time to use it for a few days and it is only the free version. I will probably buy the premium soon.
It has a better UI than JuiceDefender though not so many settings. I'm not really sure if I need those other settings.
Best thing, it connects instantly to data when I unlock the phone so I can get on to the web or viber or such to see messages directly.
If anyone wants to continue this thread you may do so but I won't make more test as for the moment. Bottom line is that the data turning off when phone's locked really do help with battery life.

Battery Life Help! BatteryStats LogCat Help Please!

Guys, I am getting terrible battery life on the newest BajaRom. I was getting decent battery life but somehow everything changed. I want to note that I cannot access the Media Battery Drain Fix in the BajaROM settings as it crashes EVERYTIME i open it. I have tried everything to install something that will fix media battery drain but I am unsure if this is what is really causing my battery drain. Please any help would greatly be appreciated!

Wakelock Detector and Greenify... are ur best friends on the Note 3.
Turnoff wifi,bluetooth,gps,etc when not in use. Set CPU to on demand. I always have power saver on unless I want to run a game... doesn't seem to effect anything else.
There are a ton of tips for Note 3 battery life...just search here...
I also use LUX for screen brightness, that made a big difference also. Change you wallpapers to darker colors... mine are some sort of black background...
I can make through the day with reasonable usage on Hyperdrive RLS8 and still have battery left...
Haven't tried BajaROM yet...

Thank you for your response. I have greenify'd most of my daily apps and I use wake lock detector and still cant find out the culprit here. It says that my SCREEN is taking up 30% of my battery life after just 2 hours unplugged and minimal use and I'm down to 82%. Can my phone just be inherently defective????
This DOESNT feel right. I NEVER had any complaints of battery with my NOTE 2

Check your data usage. I had the similar situation, saw nothing in the battery usage area....but then checked data usage. I had over 2 Gigs of data usage from EMAIL in only 2 weeks! I had been using the std email app...and get maybe 10 emails a day. Obviously something goofy going on in the sync. Yet battery usage showed next to nothing for the sync process or email app.
I removed my accounts from the email package, froze the email package and installed AquaMail and my battery usage cut by at least half....my data use flatlined.
Obviously it takes power to use the radio for a Gig a week of data....but that does NOT seem to show in battery usage.
so check your data usage...see if email is way out in front. That may be your problem.

I had the same issue with battery life after I flashed to and of the KK roms. My problem was Greenify, and I don't know why. Removing it didn't solve my problem so I'd restart from the beginning. My drain is less than 1% per hour idle without it and almost 10% per hour running all the same apps with greenify in different settings. Jasmine ROM just drained for me all the time.
*first post, be nice. I only joined because of all the trouble I went through to get my battery life back.

[RESEARCH] Zenfone 5 1.2Ghz Screen On Time

As the title said, I'm gathering some information about screen on time (SOT) of Zenfone 5 1.2Ghz (from 100 to 1-5 percent)
I want to see how my battery is after years by how much time it can handle now. Hope you guys help me.
In comment section, please including your SOT plus:
- What rom are you using? (Kernel version if can)
- Most used network: Wifi or Cellular
- Network setting: Always on or Never (Manually)
- App ram usage (Running Service in Setting/Battery or Develop Options)
Thats all I want to know for now.
Thanks!

Using stock rom Kitkat newest version, cause it uses much less battery!
I mostly use more of the Wi-Fi on always on
what is mostly using my ram is the screen ( brightness) and android
I will send more information about RAM usage later, my phone is recharging

Using 1.6ghz variant.
rom- resurrection remix nougat. but channging of roms didnt had any great impact
only wifi always on.
ram- 40-50% or below free.
sot i get varies from 2hr- 3hrs. only texting and light stuff gives around 2hr 40mins.

im using latest kitkat on my 3 years old zenfone 5 single sim variant.
this one with 100% cpu usage all time + [ full screen brightness+ bluetooth + wifi+ gps on ] from 100% to 5%;

Screen was always on in both tests. i used battery drain app to make screen always on with full brightness and wifi in second test and i get 3h45m screen time.
in first test i pushed cpu 100% and activated all gps/bluetooth/wifi etc and i get 1h53m screen time. but phone was really overheated and i scare to do it again (it was burning my hand)
actually i was shocked myself when i saw 4 h screen time when i used my phone to only read ebook all day in home with half brightness and i decided to test my phone. Results were amazing i agree, i hope it keeps that way for one more year.
i tested overnight battery usage and it dropped to 85% from 100% within 7 hours with wireless open while android sleep. i guess it might be better to close all network overnights

I wish I still kept the screenshot on Mashmallow to show you.
wireless is not the reason but the google play service. After disable a list of unneeded services, I let wireless enable all the time, gmail and other notification still can be recieved and battery drained 1% per hour (screen off). For specifically, after 6 hours over night, it will drain 6%.
screen on time is normally 3 hours but of course I have to tweak a lot to get this result. If not, battery just drains like hell.
