Droid incredible. Rooted, virtually every rom through rom manager causes my phone to battery to drain very fast.
After a charge itll drop to 90% in about twenty minutes. Iv heard thats a droid thing.
From that point, it steadies but still is losing juice FAST. Phone has been awake for 8hrs today with light usage and is currently at 70%. Gps off, wifi off, etc. No vibrating feedback, auto brightness.....all settings geared for battery conservation.
Im using Incrom 1.6 with a stock kernal. Any ideas or thoughts are appreciated as i dont stop hearing that everyone in the world is rooted and enjoying their batterys new ability. Ohhh, btw extended battery, red htc one in case that matters.

Try flashing some new kernels..try a couple out. If that doesn't work did you over charge your phone? Or use a car charger?
sent from my Dinc
Its not the battery cause when i revert to stock the battery is normal for what im used to. The change is noticable wen i use any of the custom roms.
Right now wrkng on flash radio, hit a bump waiting for email back.
Ne other suggestions from u or nebody wud be apreciatd
I use the app batterycalibration after flashing new roms it works well for me

Everybody's definition of "light usage" is different. Losing 20% in 8 hours doesn't seem that bad to me unless you litterally never turned your screen on. That said, here are some things you can try:
1. I've found that the auto brightness sucks and I'm better off just manually setting it to 25% or so. That's fine for indoor use and you can't see the screen in bright sunlight anyway regardless of the setting so why bother burning battery trying?
2. Try flashing a kernel that allows you to underclock and undervolt. Perhaps one of Ziggy's nonHAVs kernels (I have found that HAVS kernels to be unstable, but YMMV). Either use the smartass governor or setCPU to cap screen off at 384 MHz.
3. Carry a charger with you
I'd see what is using your battery in settings.
Also, you could try chad's sense (12/28 I think) incredikernel, which sets the max clock speed really low when the screen's off (defaults to smartass governer).
If you wanted to try CM7, gingerbread has a much better battery usage UI that'll give you a nice graph of battery usage vs. time for phone awake time, signal strength, wifi and some other stats.
Hi all,
I know there must be a number of threads on this, but I am amazed on how people can report that on there devices (t989/i727) that they can get over 24 hours of life.. Whilst having data on and auto syncing.. on there oem battery..
At this point in time i am running jugs 5.0 with darkside kernal and used nofrills cpu to u/c to 1.2 but i am only getting about 16-17 hours charge with basic usage ie: twitter checks and links ebay a few times a day couple of calls and moderate texting.. i havent been using power saving mode from settings as no one i have come across stating that they use it.. So i have seen gideons script for battery saving could i get an elaboration on how this works? and also are the files a simple flash via cwm?
Cheers in advanced.
I haven't tried Gideon Script so I can't speak for that. However, I do have some great battery saving suggestions for you. Try using the Streamline or Synergy Kernel. Although it is not as fast as darkside kernel and it will save you a significant amount of battery. Try it and see if its worth the sacrifice. Personally I found it well worth it as I value battery life more than performance.
Also, download the juicedefender app and set it up aggressive mode. This app is also another great tool for saving battery life.
Good luck!

Thanks for that I flashed over faux's 10u kernal im gonna see how that goes for a couple of days so far it doesn't seem to be draining the battery but i will have a better indication in couple of days.
Faux is also hard on batteries as it is a high performance kernel but i suggest you try each one as i have. Right now im on streamline and its battery life is just awesome.

gideon's script basically UC and UV's to like around 900mhz and UV 50-75
I usually alter it and bump it to 1.2-1.3and UV to around 50 not 75.
It is better than using an app to control the cpu because it's part of the boot script. darkside kernel has something similar, you can alter it in the script also.
^those inputs on kernels are correct. But each phone reacts different on each kernel. synergy doesn't play nice with mine.
A lot of users who post 24 hour+ usage.. if you look at the graph and stuff.. you can see that it wasn't in use much. I would say the average for moderate usage 16-17 hours
and uhhh why do you need it to be 24 hours? Do you not have access to a charger for most of your day? You should be home by then and getting read for bed.. lol
And also, VOICE uses more battery than DISPLAY.
There are many other phone users who are jealous of our battery life, so be happy .

This comes to my next question, understanding how to alter scripts what to do when you want to change something is something i would like to learn.. Is there any guides/tutorials as to how? I keen to learn this sort of stuff..
With regards to why I would like my battery to last is simple really, my shift times at work alter so depending on my day of course i have access to a charger but not at work, also if i were to be out for the evening I would be up at 4:30am leave my home by 5:20am (phone is unplugged) and go about my day if its the weekend and i am out and about without enough time to get a decent charge at home I would like to have peace of mind if my phone will have juice to see me through to about 3am.. So wanting a battery to last 24hrs would suit my needs. Without nit picking turn your phone off during the night for my job there could be emergencies that would require me to return to work and deal with whatever it maybe and of course personal emergencies.
Coming from a xperia x10 yes i am thank full i get the power out of the s2 compared to the x10 but if people are reporting better life why cant i have some of that
Cheers.

Unfortunately I'm in Australia every time I am on wifi i get Error: ER05 "Invalid SIM card" so I'm guessing my carrier if not all of them here don't support this feature, which is a let down I personally hadn't heard of it until I got my t989 and flicked over wifi for the first time then read about it.. Oh well.
Ideally, it is always better to have your battery drain completely and then charge fully again. If you charge often without draining completely it will impact your battery in the long run to have shorter life span.
As far as wifi calling goes, try downloading an app called GrooVe IP lite. I live in Canada and I believe it works for outside U.S. users.
Yesterday I flashed Franco's Kernel along with his app. I am running CodenameAndroid 1.6 ROM with Franco's Kernel r135 nightly.
I haven not been getting the exceptional battery life that everyone has been raving about. I understand every phone is different, and there are tons of contributing factors to battery life.
I have my screen brightness very low, location services are off, no LTE running (I'm running on 3G), however I've had wifi on all day today since I am at home. I've undervolted by using Franco's paid app and am running On Demand governor. However, I have generic hotplug turned on because I'm not always on my phone and messing with it. It's 1 o clock, and I took the phone off the charger at 8 this morning. I'm already down to 79% and my on-screen time is only 18 minutes while my idle time is 3 hours and 44 minutes. Other than that, I don't have any apps unning in the background accept for the regular things that should be running.
To the point, am I doing something wrong? It just seems weird to have that much battery drain and have my phone on idle for almost 4 hours and on-screen time to only be 18 minutes. Are my expectations too high for this kernel? I've heard awesome stats as far as battery life goes while using this kernel but I'm not seeing it. Is it because the kernel hasn't fully "baked" into the phone like some people say? I appreciate the feedback.
That doesn't sound right. Do you have BetterBatteryStats installed? That way you can find out what is keeping your phone awake whilst your screen is on.
Also, what are the rest of your kernel settings? Mine:
r135-512
384/1228
interactive (no hotplug works best for me)
I don't uv, but let SmartReflex do it's job for me.
This works best for me with BAMF (atm, but switch beween that rom and Liquid quite often). BAMF gives me best screen on time, but idles less good than Liquid, which gives me less screen on time. On a day of heavy usage, BAMF wins.
What I'm trying to say is, find your zen in rom/ kernel/ radio combo, because you might just use your phone differently then me (and others).
Oh, and I use the Samsung oem 2000mah battery. That helps too. I'm getting ~10h of use with ~4h screen on on a charge.
Hope this get's you on your way mate
So I switched from the iphone with edge to the Tmo S2 with Jugg 5.0 ROM + Go Launcher. I really appreciate the 4g speed. However, the overall experience is not as smooth as the iphone and the battery life sucks big time. I normally have to constantly plug the phone in whenever I can. It works ok when I'm at work but when I'm out all day my battery won't last more than half a day. It's so bad to the extent that I have to turn off my phone and turn on when I need to call or text so I can keep the phone alive the whole day. I tried Juice Defender but it didn't help my battery at all.
Yesterday I spent a few hours on XDA and I came up with these solution to my battery problem:
+DarkSide Digital Warfare v2.7 ROM (couldn't find 2.5.1 version)
+Flash Synergy Kernel over (supposed to give better battery)
+SetCPU app (auto detection)
+Zeam launcher
So far, it seems to be better on the battery. Is there anything else I could add to make my battery last longer? I need the phone to last at least the whole day without charge. I'm constantly on 4g looking up stocks, reading news, email, google voice, grooveip, facebook, turn by turn navigation, music, netflix, youtube ...
Thanks,
Welcome to Android.
From what it appears, you seem to be a heavy user. The most you can get out of a Android device with heavy usage is 3/4 of a day (14-18hrs) tops.
You have 2 choices, either you travel with the power cord not to far away and plug it when you need it or you invest a whooping 10$ and buy another battery.
There are tricks to keeping your battery healthy but lasting all day as a heavy user will be very difficult.
If this is a new phone it takes a week or so for the battery to settle in a hold a charge well. After a week or so you'll notice your battery is lasting longer. Also make sure that nothing is keeping your phone awake 100%. Some apps don't play nice and cause issues. Welcome to Android.
Note: navigation kills battery fast, when your using it try to plug into a car charger or something.

There are a lot of things you can do to improve battery.
1. Juice Defender (which you say you have already tried)
2. Limit the number of widgets you run or run no widgets like I do
3. Turn the screen brightness down all the way
4. Don't use Live Wallpaper, also, try to pick a dark coloured wallpaper since white/light colours seem to use up more battery.
5. Uninstall apps you don't use.
6. Turn off GPS unless you need to use it.
7. Turn off sync completely or only have your gmail sync. I don't need to be notified when I get a facebook message so I don't need it syncing every few minutes or every hour, I can check that manually myself.
8. Turn off animations.
9. Close background apps that are running that you aren't using.
10. Use Task Manager to close open apps when you are done using it. Task Manger is your friend.
11. Enable Power Saver Mode.
etc etc.
Those are the main things that I tend to do. I plug my phone in every night before I go to bed as well so I am not sure how long my battery actually lasts. But typically after 16hrs of use I still have 60% battery when I go to bed.
Currently my phone has been on for 7hrs 15mins and I have 87% battery. So you can do the math. I am not as heavy a user as you seem to be, but hope this helps. Peace.
Check out this video it helps show you how to save battery. Enjoy!
Thanks for the inputs guys. I should have said I was looking for Rom/Mod/Scripts/Apps... that can be flashed onto the rooted phone. I have done all the basic battery saving housekeepings as listed by Chochiwpg.

You could run Juggernaut with Faux Kernel and Gideon's battery scripts. Or Telus T989D stock ROM lightly tweaked with same kernel and script. Got good results on those as well. Good luck.
Btw, has anyone had tremendous increase in battery life using the after market extended battery?

If you are talking about extended batteries that don't require a custom enlarged back cover, you will not get the battery increase that you are looking for, not even close. I cannot speak for the heavy duty ones that require an enlarged back as I do not own one
Gideon's scripts are great with Juggs. Underclock it as well like 384-1080 is a great setting. Also let die all the way down and charge all the way up and repeat for a few cycles. And don't stare at your phone every few seconds either lol! Another thing are the notification lighting buttons at the bottom. Drop to 1.5 seconds.

I have the extended 3800mah battery. It's insanely fat and makes the phone look hideous. On top of that I really don't feel like the battery lasts all that long at all. It's in my pocket all day at school and by 3:30 I'm at 35%. This thing cost me 65$. Total ripoff. I'd suggest spending 20$ and buying two more regular batteries. See what that does for you all

A few things you can do on ANY ROM to improve battery life.
*) Decrease screen timeout to the lowest possible setting.
*) Adjust screen brightness to the lowest level you can tolerate.
*) Decrease the backlight key timeout to the lowest setting ( or off if you have the option )
*) Be sure to only have wifi and gps on if you are using them.
Those will help quite a bit in general however, a ROM like Juggs is meant to really take advantage of the power of your device so its probably wise to move to a different one if max battery is your goal. I love Juggs but had to move on to the AOSP stuff. Also, heed the advice above, allow the ROM a few days to "settle" before making a switch or even a judgement of its performance.
Thanks for the replies guys. So my phone lasted for 9hrs today which is a little bit of improvement. I was streaming netflix for half an hr on the train on the way back home so that may have drained the battery. I have just installed JD, will post back how it goes tomorrow.
So the extended battery is a no go eh. I really don't want to lug around a few extra batteries. I want to carry as little as possible. I normally carry my phone and my ipad but now I tend to not use the ipad much now because the S2 screen is pretty gigantic for a phone.

I know the point was already made but just to reiterate, you can get 2 Anker extended batteries (same size as regular battery) and a universal charger for like $20. This will leave you with three batteries. One for the charger, one for the pocket, and one for the phone. With this system its pretty easy to always have one full battery ready to go and one charging. The battery is small and can just go in your pocket, or maybe even in your wallet depending on your preferences. It solves the problem completely. I don't think you are going to do much better because if you are a heavy user then your battery is going to be used because your phone isn't going to be sleeping.
Good luck.

If you read my post above. I'm against the idea lugging around too many things. It's also a hassle to swap the battery and keep them all charged. I may be a heavy user but it's not like I use the phone all the time. I use the phone heavily early in the morning on the way to work and after 5pm on the way home after work. The commute each way is roughly 45 mins. In between the commutes i make a few calls and texts through GV. I don't think i'm that of a really heavy user.
Anyway, it's noon and I'm at 75% with JD on and setCPU to 384-1084mhz which is pretty promising.
Questions go in the Q&A section
Since you changed kernals, you aren't going to benefit from TDJ's battsaver script you can use with the stock 2.7 kernal.
Go lower on the max frequency. Something below 800 mhz. Setting a negative gloval mV doesn't hurt, and if you can get to -62.5, that's great.
Oh, and when using data, try GSM only...
To be honest, the larger problem with battery life is typically the user. There's no real magic on making the phone last longer other than using it less. If you're going to be power using the hell out of it by using 4g for hours streaming media, your battery is going to be ****.

Don't you think it is ironic for me to switch from the iphone to the S2 because I couldn't stand the slow 2g Edge connection then have to lower data speed to GSM (2g) just so I can use the S2 long enough?
I think the S2 is one heck of a device but the OS and Apps are not running very efficiently.
I tried the ICS ROM ARKSIDE.UCLE2:: x[BETA07.1] in the last 2 days with setCPU at 384-1026Mhz. I have had great battery life. I got home at 12 am yesterday with a 2% battery. Today it's been 7 hrs on battery and my battery is at 70%. I don't know if it is the ROM, setCPU or a combination of the two but I'm pretty happy with the phone right now. ICS is awesome too.
I highly recommend that solution to anyone having a short battery life problem with their S2.
It is a little ironic since you did bring up the comparison. What I was attempting to do was to bring the phone more into spec of an iphone to get similar battery life. You're probably going to even get better runtimes due to the battery having a much larger capacity and better screen technology. All that superior hardware packed in the t989 is going to need more juice to run.
It's great you're getting good runtimes now. From my personal experience, once I drop down to the single digit percentages, it starts lasting a lot longer per percent. If you wanted to squeeze all you can from the device, those 2000mah aftermarket cells might add another 15~30 minutes.
Currently running Jedi x11, and have had if for about a week now in order to test if there are infact major improvements.
I never really sat down with a timer and timed how long it took my phone to deplete, or charge, so I won't have an exact time duration for these, but I can confidently say, that since I got Jedi x11 on here, two things have started to happen.
1) Battery takes a very extended time in recharging. Both when in use, and set aside. - Previously, my battery would fully charge anywhere from 1 1/2 - 2 hours from about 15%.
2) My battery is depleting ridiculously fast. I type fairly fast, I'd say about avarage, and just for an example, I started this thread at 93%, and at this very moment, it's now at 91%... Even when not in use, the battery seems to deplete at a much faster rate. Tethering is also very draining now. - Previously, again, never timed it, but I am sure by the constant use of my phone that I've had for some time now, that this wasn't ever the case before.
This is just my observations: It would seem Jedi helps when the phone isn't in use. I'm not sure if this mentioned CPU sleeper helps with that or not, it's hard to tell as like I said, the battery goes down even when no major screen time is in use. Maybe it's something I have to turn on? Maybe not. Another, observation, when I am actively using the phone the battery will drop fast. Like, double fast.
And lastly, I observe the battery life will stay on a certain percentage longer than it does others. (Currently 89%) I took about 10 - 15 minutes writing this.
Any thoughts? Thanks for any replies I do get.

I'm glad I'm not the only one with this problem on this rom. Phone takes 9 hrs to fully charge, I was starting to think I'm going crazy. My battery will charge fast if I go back to stock. But I would hate to go back because of this.

Well guys, I'm not sure what's going on, but, it should be noted. The Battery on this thing just lasted the entire evening from last night (7pm) up until now, with about the same amount of use that I did the days before when I noticed abnormal battery depletion.
Currently at 47% and I've yet to charge the phone. Of course that is with the fact that I put the phone in airplane mode while I sleep for a few hours. I watched a lot of video, listened to audio, and it's as if they thing knew I wasn't pleased with what was happening, it's now behaving like it should.
This happened a few days ago also, where the battery lasted 16 hours and was at 27%. So this leads me to think it's something that happens on and off, and I have no clue what triggers it. phone ussage rains the same. Took about 5-7 minutes writing this, and the battery marker only went from 47%, to 46%.
Credit where it's due.

a lot of factors involved when it comes to battery. based on my experience, try to see what's going on with your system using this thread. noted post 1-3. also investigate about your kernel. i am using perseus kernel and my charging time is pretty good improving than on stock :good:. also i can undervolt CPU.
where you at and which service provide you use, again, have impact on this case. i used to be with t-mo and now trying h2o (att mvno) and my battery is dropping faster when i use data. i believe since at&t coverage is suck where i am at, specially when indoors, thus phone radio has to work extra harder to get reception and shorten battery's life.

In the early days of Android CPUs were not very efficient. Undervolting helped battery life. That is no longer the case. Most good kernel devs will tell you they hate under clocking because it has a placebo effect and makes their kernel unstable.

thanks ronnie. it's good to know. wondering why some of them (well known, i believe) still offering CPU voltage adjustment (up & down) if they see it inefficient ? is it because the kernel still in beta thus come with tweak utility ?
Yeah, there is definitely something awkward going on. I took my phone out of airplane mode this morning and started viewing FB for a couple minutes; a battery that was at 98% is now somehow at 92%. It's definitely on and off. I wasn't even watching any videos or anything like that.
Would all the apps that are in ram be sucking juices this badly? I had to terminate a lot of em just a minute ago. Or, is this thing somehow giving me a false charge reading? Battery seemed to charge faster than usual last night.
I'm not even fully certain the devs read these question forums at times.
I'm runnng the international XXDMB6 based ROM on mine and currently, I'm at 76% with only an hour and 3 minutes of screentime?
I don't use Wi-Fi.
My LTE signal is rather poor.
My screen generally stays around 50% but it's on auto.
Of course I let my apps sync. But that's pretty much just gmail and facebook.
I have my weather set to sync once every hour.
I uninstalled the apps that are pretty much bloat (flipfonts, the hubs, the samsung live wallpapers, musicFX since I use DPSManager, Samsung's music app and that's all I can think of)
I'm running Perseus's kernel with about 200-350mV undervolts.
Is it truly the poor LTE signal that's taking such a toll on my battery life? I used to average 5-5.5 hours before my battery dies. Now I'm betting I'll only get around 4. When I had Verizon, the power draw from LTE was unnoticeable from 3G. Is it really that different on GSM phones?

Battery life is very noticable with lte. Reason being that volte doesnt exsist yet so two or more radios jeed to be active at the same time.
Im suprised you couldnt tell a difference on verizon, it was night and day for me.

I found Battery Drain Analyzer helpful. I kept it running for a couple of months and was able to determine which apps consume the most power (widgets, by far). But, after having spent hours trying different underclocking configurations without success, I ended up buying three extra batteries. It's really awesome to not have to worry about it. I just keep them in my pocket and swap them out as needed. It's not a very technologically advanced solution, but, it sure is effective. I use this Charger for the spares. It takes a long time to charge the batteries, but charges them fully to 100%, whereas, charging the battery in the phone doesn't seem to work as well.
