Insane Battery Life

My battery test is being cut a little short, I need my phone charged for later tonight and I'm not 100% sure it will make it through the day. Here are my results so far though.
2d 5h 23m since unplugged, 12% battery remaining. Yes that is over 53 hours of moderate usage.
Incase you are wondering what im running here its not all that complicated, I wouldn't be surprised to see a lot of you getting similar life.
Fresh 1.0.1 with ffolkes kernel and setcpu set to 245 max when screen is off combined with the newest radio does the trick. Anyone able to push this thing past 3 days with moderate usage have anymore tips? I think mine would have made it over 3 days if I didnt play about an hour a day of 3d games.
Also, thinking of switching to netarchy-toastmod kernel, anyone having similar life with that kernel? Wouldn't expect it to be anything different as its mostly the underclocking saving battery.

My daily usage
30 emails
250 sms
10 calls, 60 minutes (most 3 minutes or less)
1 hour 3d gaming
auto-brightness
15 minutes web browsing
1 hour showing off the phone/someone playing with it
only use gps or music when charging in a car, which i didn't for these three days.
also, live in chicago, really well mapped for coverage, i never roam. also, rarely use 4g i have a usb modem too so no need for tethering.

props, Ive gotten mine to 34 hours, but my android system % was @ 50

Define moderate use?
Surfing the web for 3 hours a day, checking email 10 times a day, Searching the market and playing games for an hour a day?

I don't know what you mean by moderate usage When I'm browsing the web for half an hour, I can literally watch the battery drain.... and when I check usage, it's always display (mostly) and voice calls. I see neither on yours. Did you even use the phone during those 2 days?

What do you do? Play nonstop games/videos? I get 6 hours of constant gameboid.
Anyway I unrooted for the OTA just once and I got 44 hours of light texting/browsing on wifi, 50% brightness.
I want to see baked snack / toasted users... they should be getting the best battery.

Pretty much nothing. Unplug phone, go to work, carry it in my pocket and check time occasionally. Browse internet for half hour at break. Carry it in my pocket and check time occasionally. Browse internet for half hour at second break. Carry it in my pocket and check time occasionally. 8.5 hours since unplugged, <15% battery remaining.
Problem is about 0 bars service at work. Constantly switching from Sprint to Roaming.

55 hours of battery. I get 34 hours of battery with constant texting, web surfing and downloading. I'm running cm6 2.2

I'm sorry, but it's just not possible to get those kind of runtimes if you really use the tool. Try using this thing the way it was intended, not just as some kind of a toy just to see what kind of life you can get out of a charge.
I'm on the phone, got bluetooth going, wifi, ... all day long. Average 75 incoming emails, maybe the same texts, several photos for documentation, about the same or more reply's to emails, couple of hours on the phone, .... lucky to make it to 5pm.
No way anyone can convince me that they can go even 24 hrs with my use. No way.

WiFi can actually save even more battery if you are in the same location long enough, but I have no need to keep bluetooth on at all times. Updating first post with more info on my usage, probably less than yours but still use a lot.
running the phone with these settings pretty much makes it impossible for it to die on a day's use, even for really heavy users. to kill it you're gonna have to run wifi tether, gps, or 4g for a while. i never use gps unless its plugged in, and i rarely use 4g.

im gonna try it with the netarchy and let u knw at the end of 2morow

oh yea wat r your auto syncs?

I'm amazed at how much people use their phones sometimes... over 400 texts in a day? At that rate, you'd use more texts in a few days than I do in a month lol.
Impressive battery life, especially considering the amount of usage. When I've had relatively heavy use, I've managed to get the phone below 10% with ~19 hours since last charge. Pretty sure I didn't have that much actual usage though.

I miss the chance i get no update although i was registered. The update sounds good. How about wifi reception?
EDIT: I got update without signing up.

I'm on a bell atrix and I'm experiencing the same results from freezing and de bluring. I previously had about 12 hours of usage. Now I'm around 17 hours and that still was at 20%. That means when the update eventually rolls out it'll be even better. Now thats what I'm talking about

i too am amazed of the battery life after sbf'ing my phone and freezing allot of blur i did not use. i played with my phone all day yesterday, it was at 50% at 7pm. AMAZED..
love it..

Has it been confirmed when/if Bell Atrix users will be getting update? Thanks

I'm having the reverse problem. I probably get about 10 hours of use before my phone dies. I lose about 10% per hour with just playing music. Maybe my battery is screwed up.

I wish I could get the great battery life some of you report. I switched to battery saver and found the app "out of milk" was using between 56-71% cpu when completely off. Added that app to the auto end list in the factory task manager. Not sure what else I can do to improve battery life. Never gotten over 2 hours of display time and usually can't get that much.

Your battery life so far?

At the moment it seems like I'm getting around 5 minutes per percent (around 8 hours of constant use). The weird thing is that seems to be the case across all use, I get the same results from web browsing as I do reading comics in airplane mode.

I get pretty incredible standby though with set cpu. I'll go to work and come back after eight hours or more with one or two percent gone.

Yeah the standby life is amazing
Sent from my Samsung Fascinate via Tapatalk

set cpu app helped me get amazing stand by times. i mean i lose 1% every 24 hours propably.
during normal use, i get average 4-6 hours. surfing youtube, downloading, playing games. usually 5 is about right. People who say they get 8-10 hours heavy use are on one.

I would agree with 4-6 hours with constant use such as reading or twitter browsing. I previously had a Nook Color with CM7 on it and got about the same. Standby is amazing I almost never turn it off.

After about an hour of surfing or playing a game I lose about 20% so about 5 hours. But when watching videos I get around 7 or 8 hours

This sounds awesome I just got 48 hrs on included 4--5 hrs of use. Down to 2% ... wifi is set to go off with screen (after 1 min) not. Sure wat else to change

Hmmm. I was hoping that rooting/SetCPU/screen settings could get me closer to 8 hours of life, but that's not the case. I'll probably just sell the Iconia since the battery life is my main reason for owning a tablet, and in this case it isn't that much better than my laptop.

Run time.
52 hrs. %79 & moderate use. Never shut it off & still testing. Want to see how long it can go until I reach %30.

not trying to be an ass, but what are you guys using your tabs for? i run taboonay rom with thor kernel and good to very good battery life. I use my tablet all day long at work for e-mails, pdf viewing, gaming when i shouldn't be, and playing around on the internet. I wake up at 5 am everyday unplug my tab and start the day. With said usage i can go from 6ish AM till almost midnight and still have 20-30 something percent battery left. I wouldn't say i use it hard core, but i put it work. Just charge it while your asleep and it should last all day. Now on the occasion i watch movies on it it does drain the battery like a bastard but i can still get 5-7 hours of non stop movie watching on it. I really can't complain about the iconias battery at all. If you expect this thing to run like Carl Louis all day long without plugging it in you're in lala land. Theres alot of threads on how to get rid of cell usage drain, and look at whats killing your battery it may be an app or something you did settings wise to drain it faster.

Completely agree, I got mine on Saturday and apart from the initial charge it's only been plugged in twice. Used on and off throughout the day on Sunday, most of Monday evening, all Tuesday evening and all Wednesday evening, playing games and on the web with a bit of youtube and playing around. First time charged at 35% on Monday evening, second time yesterday at about 11pm as it was down to 10%. I think that's pretty damn good myself. It's on OTA 3.1 and Rooted
As for comparing to netbooks, have a look at the size of the battery in a Netbook compared to the Iconia. Of course they're going to last similar amounts of time - The Iconia has a smaller battery but has less to power versus the netbooks larger battery with more devices to power.

I'm at 67% after about 27 hours with about 2 hours of actual use. I guess that's ok. I flashed the Minimalist rom on Tuesday so I probably haven't given the battery enough time to break in. Sorry for being a *****, I'm just impatient >.<
I was kind of afraid if it would last me through a day of classes when college starts back, but I think I'll be ok.

I was getting around 5 days total with 1 to 2 hours display usage before the update to 3.1. Now it only goes 2 days when on standby with less than an hour of usage. Going to download SetCPU and try that. I have not changed anything (widgets) since before the update, so I have no idea what's eating up the battery.

Does anyone use there tablet in this post?Lol
I use my tab all-day long and I usually have 20% by the end of the day.

setcpu settings?
I'm using SetCPU as well, but getting no where near what you say. I left it on sleep last night and it drained 15% - same as before.
But, maybe I'm not using it right. I enabled the "screen off" profile and dropped the speed.
What are you doing/setting to get that standby time?

Ok, I activated a couple more profiles including "time", temp, low battery. Low battery definitely turned on and I saw the change in the icon on the bottom right. I think the "screen off" is not turning on - basically can't see it when the screen is really off . But, it's definitely draining the same amount of battery.
Am I doing something wrong?

SetCPU didn't help mine either. Tried a few different profiles. I thought the one that would help the most is Screen Off, I set it max and min to 216mhz. No difference in battery drain overnight.

General thread to discuss battery life

So...the title says it......i hope OP will make this thread sticky....
I made this thread to avoid the multiple threads discussing this matter and its solutions.
OK...everybody tell us how is his battery life......
personally mine last 1 day with heavy usage.....2 days with light usage.....
and please everybody tell us wich rom in the use...and how much using it...and all the statistics that you can get...
You are welcome to post any of your problems with batteries and solutions....

I get about the same, 1 full day with quite heavy use in terms of messaging and surfing.. It does drain alot faster playing games or watching videos.

2 days with medium usage 3G, 4 days 2G heavy usage.
I have always said this phone has really good battery life, and for me it does.

right now my battery is on 32% and from the last charge past 1d 8h 12m with medium use

I had 3-4 days with stock 2.1 with my typical light usage. Now with stock 2.3.3 this increased to 5-6 days.
(few calls per day, no games, no music, 3G almost always disabled)

Compared with latest 2.1 with bb 67 on stock 2.3.3 battery life is worse. 1 day with heavy usage, and 2 days with light usage - 2g connected constantly.

I suggest everybody post screenshots and what rom you are using.

Sometimes, it doesn't even hold for on day. Heavy usage. Web, Facebook, gmail sync, twitter sync (and a couple of others) perhaps I should change the sync.

Does the mobile networks play a role when it comes to battery life in terms of network coverage etc... Mine fully charged with average usage lasts less than 24 hours. Well i do a bit of surfing and FB and mail sync in on. Is it due to that ? I did a calibration as well after flashing wolfs rom from stock.
Pls advice !

One hour of you tube? playing videos obviously... thats just fine, i do pretty much the same but with gaming instead of youtube and a couple of hours talking, wifi and 3g always on, sync every 30 mins constantly checkin facebook, twiter and xda till ot get to arond 15% in like 7 hours
running wolfbreak´s gb 4.0.3 ROM with stock kernel and oc and uv (they work fine together for me)

There's a theory.....and i personally tested it and it works....
if you wanna get a great battery you must charge it at the percent of 20 or 15.....and it lasts a 2 days...
and i charged it at 0%..it keep about 4 hours charging...and it doesnt last a day....
im not very sure.....test it guys and see it if it works and tell me the results.....
dont forget about the THANKS botton.....

these threads are pointless imo...
everyone's usage is different, and you always get people saying "oh my phone lasts 3 weeks on a single change".... Pfft sure it does
There is no point in really comparing, yes you can get great battery life if you don't use your phone but what does that prove?

So what?
I'm giving my opinion on the topic of battery life comparisons in general, it was not any way offensive to you.
I'm simply stating that unless there is a way to objectively measure that the usage was the same, what does "this many hours" actually really mean?
Plus everyone's ideas of "moderate","heavy", etc... are completely different.

Hey guys,
I charge at 15% and my battery lasts for 7 hours. I use 2G data on always, no wifi, no gps, no music, no videos, but heavy surfing and apps download and update.
I think this battery life depends on the climate conditions where u stay.
I stay in India where temperature is above 40 deg.

shouldn't you be looking at 'screen on' time rather than how many hours it lasts after you unplug ?

Didn't someone post a screenshot of 4 days light use with 5 hour 30min screenshot on the battery thread?
