Using the app "Battery Monitor Widget" I have determined the following....
My Droid X sleeps at -5 mA while sleeping.
My T-Bolt sleeps at -48 mA or more (usually much more) while sleeping.
Both phones run Gingerbread.
Both phones have the same apps, running.
Why does the T-Bolt draw so much more mA's?
I've turned off the 4G radio and it didn't help.
Any other ideas?
Thanks.
Your T-Bolt is not alone, mine runs in the -40's too. Recently into the high -30's with some undervolting. What rom and kernel are you using? I am on CM7.
GingerBamf Remix with Imoseyon 2.5.3test7 running Extreme and Interactive.
i have very bad standbye life on mine running BAMF froyo versions too. I really want to know what is causing the horrible drain. Nothing really shows up as keeping the phone awake or anything.
I noticed this the other night. I went to sleep around 3:30am (...after tending to crying daughter) at about 50% battery and woke up at 7am to a dead TB. Plugged TB and checked System Panel app and saw my battery drain in about 2 hours with no device usage at that time span but 10% cpu activity while in sleep mode. I have been keeping WiFi on at the house lately which has helped on battery life when connected but have also noticed my TB having a hard time connecting to Wifi when I get back home or waking out of sleep mode. Does Wifi connection cycle in sleep mode if it is having a hard time connecting? Also had two reboots for no reason the last few days as well. I love this TB but these little annoyances are.....well annoying!
Every time I root, I end up going back to stock. To me, it seems to runs smoother and with better battery life than any Rom and kernel mix I've tried.
My phone lasts me all day with some texting, web surfing, playing music, a few calls, some tethering, and some YouTube. When I plug my phone in at night I'm usually down to 40% give or take.
I also use green power to manage my data and WiFi. It works great.
Over night I might loose 1% but thats it.
Just my opinion.

Hey guys what's a good app that you use to track that information for your battery discharge rate?
Nvm lol just reread your post. Thanks.
SETCPU
Im assuming your rooted if so install SETCPU and in Profiles you can turn the voltage all the way down on the "Screen Off" option but make sure you check the ENABLE box and after you wake the phone up if it seems to be a little choppy just go back to SETCPU and check the ENABLE box again which will disable it, works for me
I am running stock Rom with basic tweaks (display, background data) and just uninstalled the task manager I was using and improved my battery life by 30%. I now go almost all day with moderate use with out having to recharge.

Let me just clarify that my battery life is fine. I only lose a few % overnight. I was just confirming to the op that -40's is normal.
Just wondering since updated to XXLPQ if your battery life has changed compared to 2.3.6. Mine has suffered a noticeable decrease in battery life as i can notice a number of extra apps running in the background compared to 2.3.6. Any input/solutions?

Better Battery Life
In stock gingerbread I usually got 1 1/2 day of life with 2-3 hours of screen on. With CheckROM v6 I got around 2 days with 4 hours of screen on. Now with ICS and CF-root I got with the first full charge 1 1/2 day with 5:30 hours of screen on!
I froze all the junk that comes with the ROM, I only have a partial wakelock AudioOut_1 that is driving crazy. So far I'm quite happy with it.
Please search the forum we have so many Battery ICS threads already!
Battery life is def better with ICS, have you calibrated your battery since the update?

I'm not having any real battery issues myself, but since quite a few people report it I decided to call Samsung and ask if they will provide a rollback to 2.3.5 or what they could do to alleviate the issue.
And the answer was, as a technician had told, to solve the battery issue I should do the following:
1.) Charge the mobile to 100%
2.) Let the device drain battery as "normal" until around 9%
3.) Then open applications that drain battery fast until the phone shuts off
4.) With the phone in off-mode and drained recharge it to 100%, and do not turn on the phone at all during this time
5.) Turn on phone, and the battery life should be back to normal
Seriously, this was the official answer I got from Samsung support technician. Sounds like some old woman's advice, but hey if anyone with battery issue want to try then why not. At any rate it can't hurt

Isn't the whole "battery calibration" thing just an hoax? Been reading some lines around that disprove any effectiveness in doing so.
I am tired of my Amaze, the battery barely lasts me more than 5-6 hours and these drops are unbearable.
I started my day 9am today and the battery was down to 20% at precisely 1:04pm.
Just look at these drops.....
Rooted? Rom?
Chuck Norris can but Walker Texas Ranger can't.
On stock rom and stock battery the battery life on the amaze is terrible.
I have my girls amaze rooted running a custom rom, kernel with setcpu, juice defender and anker extended battery. Now it lasts her all day with out charge in between.

I don't know what you people do, but I consider myself semi heavy user. Today I streamed BT music for an hour at the gym, streamed one movie off Netflix and watched a good few YouTube wrestling matches and had a few calls here and there and a good 50 texts....reading some off the Kindle app and I got 11 hours before a charge.
I get 12-18 on normal usage. Was a light day at work, lol!
Want amazing battery life, then go back to an old school BB phone.....
I am still stock, lol!

This does not look good at all especially the last drop. You might have a rogue app. I would factory reset and start over only few apps at a time so I can identify the app. You may also wanna try other battery like anker.

This behaviour is definitely irregular... Those sharp drops and sudden spikes could be from the battery not being calibrated properly. On average, my Amaze with stock battery lasts me about 14-16 hours with 2.5-3 hours of screen time (lowest brightness most of the time).

Most android phones really need to be rooted so you can fully tweak the battery life. My amaze got roughly 16 hours with normal to heavy use with bullet proof 4.0. My phone I'm using now, the mytouch 4g gets around 24 hours with the same use. Before I would be lucky to get 8 hours with either phone. IV learned that you can either complain about things, do something about it, or just get an iPhone and go away . The beauty of android is the ability to go in and tweak.

averaging ~ 15-19 hrs of heavy usage a day on sense 3.5 rc1.7, sometimes Ill use juice defender to help with the longer work shifts but honestly its a huge difference from when I was stock.
its no different from when I was stock on my g2 to when I was rooted, sometimes you just have to tweak a few things to see a vast improvement.
Morning all,
I just woke up and unplugged my phone from the charger after leaving it to charge all night, right. As soon as I unplugged it, THE BATTERY DROPS 96% IN A MATTER OF SECONDS and I get the less than 5% of battery remain. I was like WTF?!?
I believe I found my problem....
Btw, I am on a rooted stock rom and I would consider myself a normal user. Calls, sms, and emails are the primary uses of my phone.
I am completely stock and get about 16hrs to a charge... I run miui music or stock music app for roughly 4 to 6 hrs a day and surf here and market and a bit of gaming.
I set screen brightness to 20% and keep my internet and blue tooth etc off most of the day....
I desperately want to debloat but I'm holding stock till ICS.
Rogue app sounds right along with the bloat like Google maps and Facebook eating up our batteries..
I also use a task manager to kill on command......
We have a hodgepodge setup of bloatware and settings in stock format... But I'm waiting and earning an ulcer till ICS as I know the upgrade will open the door to real development of truly good stuff

I was getting about 3 hours of battery life on Faux's kernel. When I switched to stock I was getting 18 hours
This is my battery from when I woke up until now, about 10 hours so far.
Light usage so far, just while I was at work. Screen was on for an hour.
I'm very happy with my battery life, if I leave the screen off I barely lose any battery not even 1% an hour.

Hi all,
I was wondering what a "normal" battery usage is for the S2.
Mine (cm9) 10% per hour, pretty much idle.
Sent from my GT-I9100 using xda premium
There is no "normal" battery life. There are literally a million variables and thus no answer.
In terms of expectations - you would expect more life per charge from Stock GB, Custom GB, Stock ICS, Custom ICS in that order. Remember that ICS by its nature uses more resources generally and will not match GB for battery life.
Also, ignore wild claims about many hours with the screen on - it is a trick - they have the screen all black so no current draw...
Last time i was using Ressurection remix v1.3 AOKP i was getting 7 hours per 3% Phone was idle all the time Now i am using Thebyan 4.2 and battery drops 6% per 8 hours (idle all time )
And I am getting around 4:20 hours of battery life with normal usage ( screen on all the time plus Browsing via WIFI) Brightness - 10 percentage.
And while playing HD Games only 90 minutes !!
Well i prefer screen-on time over idle time

^^ this. Probably the best answer I've seen on here all week. No such animal. Just like there's no way you're going to get the same 'performance' with a given rom or kernel as someone else; which makes the "What's the best rom for <insert criteria here>' questions redundant and a waste of time as well.
This morning from 100 to 78 in 2 hours using edge and tapatalk xda forum. Screen at 50, GPS on, little Facebook. on formula one rom
Four days less if i switch the phone on .Even less if i use it .
jje
I get about 2 hours per 1% battery. That is with wifi on and screen off. If I have wifi turned off and airplane mode on I will get about 7 hours per 1% battery.
I always have my phone in airplane mode turned on, and wifi turned on, as I don't use the mobile network, and I am always in range of a wifi network
Cheers corey

CM9 and a lot of AOKP roms drain battery faster. Anyway my battery drain when idle is roughly 1% every 7 hours
well i get a decent life ,iam fully loaded an always install something,android is power hungry,so i don expect much of batt life...but i turn off wat iam not using like data,,,an in the night i listen to dubstep so i keep in flight mode an in morning switch back,so yes neva measured batt life,but happy....
I decided to make a thread to see what kind of battery life and performance people are getting with their devices. Please include what build you're on, the kernel you're using, any special apps you're using, and any comments you have about your setup.
Guess I'll start..
Build: The Base 0.7.3 (4.0.4)
Kernel: sk8's 2.2 ICS kernel
Apps: Android Tuner Pro and SetCPU
I use Android Tuner for voltage control and governor settings. SetCPU is used for profiles to adjust the CPU frequencies for different apps. As well as a lot of tweaks I've applied. Forgot to take a screenshot before I charged my phone, but I'm able to push 36hours with about 6 hours of screen on time.

Pure stock rooted, locked bootloader, frozen bloatware. 18000+ on average Antutu, over 7000 Quadrant average. Battery goes from 12 hours to 27 hours, my two broadest 'average' ranges. 12 had moderate use, 27 had light use, data off, power saver on.

Make sure you also post your screen on time like the OP. Your ROM, kernel, tweaks, etc are important, but screen on time is the closest we can get to a constant variable.
On 12 hours, screen on was about 3 hours. 27 it was about 45 minutes. I've deleted the screenshots though.

I am running rooted Stock ROM/Kernel (waiting for official JB update) with unlocked bootloader. I have been recieving terrible battery life though! I've tried calibrating it and still had issues. Besides that, I get like -5% every 7 minutes of low-mild screen on use even with Eco, Powersave, and underclocked at 384 MHz all enabled. About -10% every hour with the screen off. :/ I'm going to go ahead and factory reset/wipe and restore my apps. Hopefully this will solve my jacked up battery.
EDIT:
I think the battery has improved just a tiny bit after factory resetting. It not exactly satisfactory (about -9% every hour with screen off), but I think that might be normal for smartphones, right?? Under battery stats, it shows "Android OS" as using over 40% of the battery. I don't think that's normal.

That's the main reason why I use The Base. On top of being speedy, there a "fix" option for fast dormancy which helped me tremendously seeing as I rarely use LTE. It's like.. It disables it when not in use, but enables it when needed.

So what is defined as "On Screen time"? I charged my phone all night and this morning unplugged the phone and turned on my screen and told it to not go turn off ever. I was hoping to test out the heating issue, as the previous version would start to get hot after half an hour of screen time. I left it sitting on my desk all day and after about 7 hours it ran down to 15 percent but when i look at "on screen time" it shows only about 5 hours (it should be at 7 hours as i started this when i got to work 7 hours ago...). I literaly just left my phone on and didn't interact with it at all, all day. Seems a whole lot better to me than the phone i got this as a replacement for. But was just wondering what is calculated for on screen time.
BTW: This is stock phone, just pulled out of the factory box. Not rooted, not unlocked, don't even have any accounts tied to it or moved any icons around.
It's best to track battery life/screen on time with every day use. Or for those that are heavy users, with games and such. Just leaving my phone on idle with screen on I can get about 11 hours as all my cores but 1 go offline while one remains at 384MHz.

You can do the fast dormancy fix, even on stock ICS. There's a thread, in this section, that's dedicated to it (there's even an app, if you are unsure of doing the code submission that's outlined in the thread). It makes a HUGE difference, in my battery life.

Pretty sweet. This is my favorite phone of all time.
Before anyone jumps all over me, I realize the phone has been in standby for all but 5-10 mins of this time. Still can't believe how little battery it has used on standby.
