How did you manage that? I had the phone in standby mode overnight for 9 hours and was down to 77%? This was after a factory reset with no appls installed, brightness all the way down, no data/sync on, no animations,etc.?

Idk I just notice my battery icon still looks full when usual at this time its halfway to aquarter way down idk mauve phone is now in a normal cycle I know I installed touteur yesterday since that was raping my battery and use the official twitter now and been using this app using the engadget app and little web browsing

Uhh your battery will "look 80 percent full" until it hits 69 percent (I think).
Go into settings > About Phone > Status to see what your real battery lvl is.

That's how I got 80% it looked full but said 80%
Now says 74% still best battery day I've had

Mines weird. It charges on standby. Lol tested twice. One day went to sleep for four hours on a 78% charge, woke up it was at 79%. This morning I slept 3 hours it left it on 28% woke up with 29%.... lmaoooo

My day today was similar but not quite as good.
7 and a half hours off the charger and 75% battery remaining. This is with texting moderate web browsing, facebook a market download and heavy GPS usage while trying to tweak setting to get a more reliable fix for the GPS issues.

Does anyone know if switching from 3G/E and vice versa consumes more power? In other words if you constantly switch from 3G to Edge or GPRS does this cause your phone to consume more power than if you were in same 3G cell entire time?

I'm in orlando so 3g all thee time

How is your display so slow at under 40%? My usage is always around the 60-75% of battery usage for the display. This is with a live wall paper or regular wall paper. Any settings you want to share with us?

I get 3G most of the time as well, but in many places where i used to get 3G on G1, i only get E now on Vibrant.
Many years ago I read that radios power consumption spikes up significantly when its doing a call "handshake" or switching from one cell tower to another on voice calls. It would be reasonable to assume that because Vibrant radio is weaker, it leads to more power being consumed due to more frequent cell and data protocol type switching.

I think the display percentage is low because the GPS usage I had took a decent chunk of the battery.
No special settings to speak of. I use ADW launcher usually have brightness down all the way unless I am using the phone outdoors (which is not very often) I have a regular background.
The only thing I can say that I changed recently that might be helping my battery life is that I changed my ATK settings to put the security level at medium while already ste to Crazy and to kill on screen off.

No god's and mine 45%

So you are using ATK. I had it on my phone earlier this week and in standby mode I was only using like 6% in 10 hours. Last night I did a factory reset (phone was lagging) and did not have ATK installed (had default wallpaper, brightness down all the way, no animations) and in 9 hours I dropped to 77% just in standby mode.
So I installed ATK again today and see how it goes. I haven't installed my apps again and using standard touchwiz (had launcherpro installed before the factory reset). Previously I had ATK set on Crazy and kill on screen off as well. I think I had security on High though.

My Battery Life WOW! *Pic for Proof*

Using Myn's ROM with the Battery Tweak, I have FaceBook syncing and I have 2 gmail accounts syncing along with Weather every 3 hours, Facebook every 2 hours.
Nothing else as of now and using Itching Thumb App.

Not needed. From the pic he attached it's obvious the phone was in standby most of the time.

Man, you even use ya phone?
What is with this obsession of battery life goin on 'round here? I say, as long as you can get better battery life than a stock rom, you've won. Keeping the phone on for a day or two without charging seems like a good idea, but everyday isn't the same, and one day you may need to use it way more than any other day..if you start that day off with only 30% just because you wanted to see how long your battery would last, then you really gotta limit how often you use your phone just so that it can make it till the next time your around a charger.

The battery needs to be charged? I bought my phone back in June. The battery is now at 70%. I figured I just had to buy a new one when this one runs out.

Barely used phone. Come on.

Display 4%? Is that possible?

I can go a full day and a half, 36 hours, without a charge and I am using the original sense android... and I use my phone normally, I text, read usatoday, tmz, check email a few times, use the xda app... and I have wifi on all the time! What's this beef with battery life on these forums? Mine lasts forever! I just have things update manually, I don't let anything run without my permission.
I do, however, turn my phone off the 6 hours I am sleeping.

wifi is on = low battery usage, atleast in my experience.

Indeed. I got 1 day and 19 hours on stock nonrooted 2.2 back. and i used it for some medium texting. and some gps applications...maybe 2-3 hours max awake time. i dont think you used it much...the excessive 3G usage from FB doesnt mean anything.

You should be able to get what you're looking for from the Spare Parts app.

According to my calculation thats is 69min of display usage.

According to mine, it's 122 min of screen on usage.
I had this scenario on my phone running myn's rls2 + king cfs #11 yesterday:
since unplugged - 24 hours
display on - 1 hour 25 minutes
charge remaining - 50%.

so i wanted to find out how long the battery would last on standby, and to my surprise.. it turned out to be nearly 58 hrs!!! that was on stock sense rom. non-rooted. and of course with very very minimal use. i basically just left the phone alone on my desk or in my pocket all day.
here is the screenshot i took back in july:
but that kind of battery life is unrealistic with normal usage. I am a moderate user (on the higher side), and i typically put my evo on charge everyday in the morning when i get to work (on weekdays). so, the charge on my phone lasts about 25 hrs with normal usage, that usually means about 4-5hrs of Awake Time. this is after rooting the phone. and i am using a stock rooted sense rom. i have had similar results before rooting the phone as well.
on weekends, i find myself charging the phone about 3 times (over 2 days), as the usage of the phone goes very very high.
i have a charger on my desk at work for the weekday charging, and a charger in my car for the weekends.
i have recently installed setCPU, and havent really seen that making too much of a difference, but that perhaps has to do with my usage pattern.
as pointed out in many a threads, signal strength is one major factor when it comes to battery drain. i live in Atlanta and i have great Sprint coverage where I am located, and that makes a world of difference.

it would help if you indicate the battery life that you were getting on stock or any other rom you were using prior to this. because there are so many variables that come into play as far as battery life is concerned. so that will help put your claim into some perspective

hahah.. funny

How much battery is used for you with continous usage of 30min/1hr?

Just trying to get a feel if my battery is normal or not.
With continuous internet usage over wifi, it takes up 30%/hr on the STOCK battery.
With the Sprint OEM Extended battery (2600mah), it only takes up 10-12%/hr.
So I'm wondering if my stock battery just sucks or if the Sprint extended battery is actually more around 3500mah...
How much battery is used with continuous internet usage for you?

I was just browsing the forums here for an hour and 44 minutes - little g reader too - and the first hour recorded roughly 11 percent of battery loss with straight use, shown in juice plotter. Screen brightness at lowest and wifi.
That said if I was popping tabs left and right and jumping around in the browser it would be a bit different. I think I was on Deadspin for maybe 15 minutes though. Dolphin Mini.
SWYPED from my SUPASONIC

I'm getting about 15% an hour on mikfroyo (undervolted htc 15). that's about what I used to get on older build roms (evio) and stock kernels.

Sent from my PC36100 using Tapatalk

Well, guess I enabled wifi after 20 minutes or so. Between 20-25 percent in 2 hours 10 min didn't have a full charge. Just started using juice plotter to track how little battery gets used when phone idle. Cool little app! Always so late to the party.
SWYPED from my SUPASONIC

wifi strength is excellent, i'm only 8 ft from the source (in my room). i keep the screen brightness at the lowest setting since i lay in bed and use the phone before i sleep for about 30 min.
i'm extremely surprised at the drainage of both yours with just the stock battery. maybe i should try and get an exchange through Sprint.

some more info on your setup? maybe it's a software issue. try system panel to see what's running and how much it's been running. it also gives you cpu speed which should throttle back when there is no interaction with the device.
Sent from my PC36100 using Tapatalk

i'm on Fresh 3.5.0.1 with the SBC kernel. I don't have any weird drainage issues over night, i sleep with it at 80% and wake up with it with about a <5% drop. I just have the usual apps running, nothing too crazy. All I use the phone for really is to browse the web.
I find that System Panel doesn't reallly help too much when i had a weird drainage issue a few months back, a hard data reset fixed that.

That pic shows 14% loss in about 30 minutes.
Which is normal - about 0.5% a minute.

That would be normal usage with 3G. Not sure about wifi.

Wherever answers are in this thread should be in mA since percentages are meaningless on the Evo.

look at 90%-83% when screen is constantly on for 30 min. 100-90% always drops fast.

I wouldn't say meaningless. i.e. 10% drain from a 1500 mAh battery is 150 mA no matter how you slice it.

No it's not. It wouldn't be even on most Li-ion batteries in the first place, but even more so on the Evo. The firmware is programmed to oscillate between ~ 500mA and -500mA depending on voltage, all while keeping the status you see at 100%. Download Battery Monitor Widget to see this in action.

Great battery life!

Off the changer at about 7am then listen to music for awhile to drown out some boring teachers! then some games at lunch. A few texts here and there and calls for about 10 minutes. Its now 12:27 and I still have 67% battery!
I gotta put it on the charger before I go to bed so I can start fresh tomorrow.

Battery life varies GREATY with usage; a good indicator of usage would be your on-screen time.
What is your on-screen time?
Also we have another similar thread here:

There is another thread like this one with real usage battery life...
That being said, I agree that this combo has awesome battery life. I'm using it myself. I froze a few pre-installed apps, and turned auto sync off, and my phone seriously dropped 1% overnight with wifi on. That's pretty amazing. I don't have deep idol on, stock voltages, and 200/1200 with interactiveX.

I don't have my phone on me right now, so I'll post what I froze in a minute. Freezing apps stops them from using up RAM and CPU time. In turn that saves battery. It doesn't save as much as turning off the auto sync though.

my phone was 1 day and 15 hrs without a charger but this rom have bugs like home buttom not working screen close (need to be like old tv) etc etc....

I turned off auto sync and backup but my battery still drains pretty fast even when on 2G all the time.
I've frozen Maps and Talk but that doesn't seem to help.
I noticed that my phone awake time is high enough when the screen off although it can go to deep sleep normally.
I also noticed that Google Services has high % of battery use.
Any idea of what I'm doing wrong?
I'm sure that I have turned off auto sync.
But this Google Services still drains my battery.

What phone do you have? I have a 4g, so it's on CDMA. I know that the auto sync takes up more power on CDMA networks then it does on GSM. Do you have GPS on? What about your NFC? Those both take up battery.

There's an app on the market called titanium backup. You can "freeze" apps so they aren't running and don't show up anywhere. It stops them from running in the background.

I have an i9023, the GSM one.
Yes I've turned off almost all that my phone doesn't even deserve a title of smartphone.

You have to freeze apps like Google + Google wallet ( stuff you never use) just make sure the system does not need it or you'll run into issues. Also use a task killer but disable auto kill and only kill when u need too.

Task killers are a waste of space. When will people learn how to exit apps properly and know that the android system handles its memory just fine on its own?

[Official] battery stats thread

Once we get charged up (and back down), let's see how the battery life in the S4 compares to the quad core.
Please make sure to include your screen on time, as that is the best indicator of light/heavy use.

pleasantly surprised
I can't believe how good the battery has been so far, 84% after 13hours (over night)
I am a light user. still - that is impressive for stock. I never got close to that with my OG Epic on stock which was usually 3% per hour.

Not too bad for first day with moderate to heavy use!

This is heavy usage. Screen on time of 3.5 hours. Downloading Max Payne and a lot of apps. Downloading and listening to audio on Google chrome. Lots of Pulse usage. Games, YouTube, and 30 minutes of phone calls.

one thing im NOT noticing here is Allshare Service taking up a high percentage in your guys battery stats...
on mine its been at 7-9% and i dont know why, i have something waking up my phone when the screen is off and it might be that... ive forced stop, but i check later and its active again, ive disabled the service and the Allshare play in the application manager but still comes back on... hmmm i think im gonna have to root and just get rid of that file, or freeze it or something

Question... Does having all the motion settings on effect the battery? Also does having the NFC and sbeam on hurt the battery?

I wish I could get some stats like that. The screenshots are while I was sleeping and 7% seems like a lot of drain for it just sitting there. Only thing on was wifi. Cell standby time on is always the same as the time on battery, is that normal?
edit: the phone now shows 79% battery left with time on battery of 12h 46m; cell standby the exact same; screen on at 9% with time on of 48m. I'm fully stock and running power save mode.

Here are my stats. I think the battery life isn't too bad so far but we will see.

No, they will carry over until you re-charge or change the battery.
I was going to make a thread like this, but it was already here! Here are my results after my second full charge and regular usage. The results are on par with my fully modified and decked out Epic. Of course, this device has a bigger battery, but it also has a larger screen. Between the hardware and software upgrades, I'm very impressed with the stock battery life. This includes wifi on at all times as well as signal w/data. Some motion features are enabled, nfc is not, and google sync is off (I use stock email). Now how much further can this be improved?? Remember not to be discouraged, Screen On times will vary depending on what the phone is used for. Showing pictures is much less battery intensive than watching YouTube videos.
