Incredible Battery Issue!!

I put the leaked 2.2 update onto my phone and it has been great. I have only had one issue with it thus far. Starting yesterday my battery life plummeted drastically out of the blue. It seems like it came out of thin air. There is no water damage or anything. I am avoiding doing a data reset. Does any one have any other suggestions?

Is your phone staying constantly awake? Is there an App causing it stay running? Are all of your apps up to date?
I've been on a 2.2 ROM for over a month and I have great battery life, even with my overclocked kernel.

I use Advanced Task Killer and my phone goes to sleep after 1 min. 2.2 Worked perfect with great bettery life for about 2 weeks. But last night everything went downhill. It maybe an App i downloaded? but i looked in my apps and things seemed to look normal.

Do you have the task killer automatically set to kill after a certain amount of time? If you do you may be killing processes only to have them be restarted right away by android system, then killed again, restarts...and so on. That will kill your battery like crazy! To be honest, try going 24 hours without your task killer and see what happens, I noticed an improvement. The way android manages it's processes there is no need for a 3rd party task killer. Also try the KingzKernel's they are fantastic with battery life.

K, regardless, uninstall it for 1 day. U may notice a decrease in it benchmarks but ur actual performance will not change. I was a skeptic too, just give it a shot.

I'm having the exact same issue. I flashed the virtuous 2.2 rom. The battery is dropping waaay too fast. This needs to be figured out

I'm having the exact same issue. I just flashed SkyRaider 2.5.2 the other night and Radio 2.15.
The problem I'm having is that my charge is taking almost 4-5 hours to charge when it use to only take a couple hours. Also, my battery is draining QUICK.
I just clocked it and I went from 100% battery after a 12-hour charge to 93% in about five minutes.
PLEASE, someone help with this issue.

I never had any issues with the original 7/28 leak (or whatever the date was), and once having the bugs worked out, never bothered with the 8/1 leak. I did the 8/26 leak as soon as it came out and was plagued with charge times exceeding my 7-hour per day sleep schedule, and battery life that would drop drastically with the screen off. I literally went from 40% to 5% in a matter of two hours with my phone sitting on my desk, screen off. I used nandroid restore to go back to the 7/28 leak i had backed up. I'm not sure where the bug is, but I hope Verizon/HTC release this update soon, so the OTHER 95% of Incredible owners can start *****ing too. Then maybe something will get done.

I tried bump charging this morning and it made no difference whatsoever. Withing 2 hours I'm at 35%. No Facebook syncing or really anything syncing for that matter... Just a crappy battery issue. Tried different Kernels and no difference which leads me to believe it may be Froyo or the Rom I'm using which is the virtuous Rom but that doesn't make sense....

I'm surprised this has not been addressed on a much larger scale within the XDA community. There is no way anyone could enjoy their Dinc with that much battery drain.
I am using the 3500 mAh battery and with stock phone and no root I was able to charge my phone in about an hour and could get nearly 2 days with heavy usage. Now I'm not sure I can even get 12 hours, but I haven't fully tested that theory yet.
My plan today is to do a full charge (Which will be done in a matter of minutes) and then I am going to do some clocking to see exactly how long it takes to discharge.
Regardless, why is this not a major concern in the community? I only see a few posts relating to it.

Ok, so I think this has been brought up before.
When my phone is at a complete IDLE (89%), my CPU is rocking out at 900+MHz.... I think this is what is causing my severe battery drain. Can any developers respond to this or can someone else advise? My sister who uses her stock phone with no root, etc is idling between 245MHz and 320MHz.
My battery is dropping way to quick and this has to be the answer. Please help. Thanks!

Thing is...
If you're on this forum, you're probably a constant tweeker. The so called "battery issue" is all over the place depending on who you talk to. I wrote "Making Your Droid's Battery Incredible" over at my website, but essentially you need to figure this out yourself. Battery usage depends on so many things like the programs you run, the kernel you're using, and the battery you have (and the condition of said battery). If there were a uniform problem, it would be much easier to identify.
Oh, and if you're humming along at 900mhz while idle, try SetCPU.

Is this normal battery life?

Or is this a bad unit?

I was getting life like that until I upgraded my ROM to Calkulin's 2.0. Heres a screen shot.

BlStboy your battery life is normal for sure. Im am totally obsessed you could say with battery life. I was getting 5+ hours on stock rom with stock kernel and then tried out star burst and it went to 3 1/2 average. On caulkin's its the same but with much better performance and reliability. Idk why stock gave me such good life. But i know i. Like caulkin's the best because his is a bit smoother over stock and allows more tweeks. Ill upload my current this. Minute battery screenie's for you buddy. One sec

Here are the pics i promised. Almost exactly the same as yours. ICS should increase battery life some i imagine as its all hardware accelerates and new OS's always provide better battery tweaks. Hope thia helps, if it does dont mind hittinf the thanks button
EDIT- the only reason it shows my battery life at 24% is because i stuck my gf's battery in because my battery was at 4% and i didnt want it to die while i uploaded the pictures to you

im currently on 35hours and at 18%. i am runnning Calkulin's 2.0 (not bare) and ek02 modem. also right after installing 2.0 i charged my battery with wall charger to 100%, then quickly plugged into my PC until it said 100%. then i pulled the battery out for 100 seconds then rebooted. i am currently still on that cycle.

Thanks for the replys guys as soon as I get my jig im installing culkin 2.0 :-D I wanted to wait for an official ota so I wont get stuck like the eg31

5+ hours? I watch netflix with 30% brightness for 6 hours and then my phone dies. But i get at least 14-18 hours out of my phone with heavy usage. Blazing ROM EG31 Modem.

Wipe battery stats and calibrate.
It's a good day when I get over 12 hours w/ ~2-3 hours of screen on time (calk's rom). Quite disappointing, but better than the 6-8 hours I used to get on stock before calibration.

...
I've only had the phone for about 2 days now. With just a few short calls and quite heavy wifi use (customizing!), I think I got around 5-6 hours? I could be wrong though..

I've honestly been getting different results fairly regularly. I spent about two weeks on Calkulin's 1.5a, and during that time I had days where I would go twenty-six hours before getting to 10%; today, I'm at just under five hours and sititng at 73%. I cannot get consistency from it.

Bad battery?

I have had some issues where my phone won't wake up so I have to pull the battery and when it reboots the battery drops like 20%. Is this a bad battery or what causes this?

what rom are you running? if i remember correctly there was an issue with one of the roms but i cant remember. but I do remember it being an older rom that did that.
as for the batt. % i get that all the time even when i reboot..tho i get a bigger drop in % when the batter is lower.. like if i was at 50% batt power.. reboot then i would be like at 20% batt. power.. but it would stay at 20% for a really long time till it caught up with it. and sometimes the batter % would rise up a bit. but eventually start to go down again.
But maybe I have a bad battery also.. so im not sure...lol

I had the exact same problem my phone would constantly reboot and shut itself off then I would lose half my battery % I thought it was the battery too so I returned it to stock and took it to sprint they looked at the phone for 2 hours and said there was absolutely nothing wrong with it or the battery. So I took it home and re rooted using Qbking77's latest method the one that does not give you the yellow triangle and I have not had one reboot or sleep of death since and the phone just runs soo much better now so I think it was a bad root for me. I would try re rooting with the latest method and see what that does for you. Also ya out of curiosity what rom are you using because I have heard similar stories from people running the ICS leaks.

I'm running caulk's fc07 1.1 with the repacked kernal. It happened to me before on GB while also running caulk's rom but it only a few times. It seems to happen more now. Here is a screen of my battery
Sent from my SPH-D710 using XDA Premium App

I believe this would happen more in most recent ROMs because everyone is focusing how fast we can run it or how long we can use it. In either case, there are lots of tweaks and mechanism to make it fast and last long.
For the battery life, there is some background process monitoring unnecessary processes and kills those or tweaks to less frequently monitor the status. So, if the process which is related to battery life is killed, next time when it wake up, it may detect the different life time based on current Voltage or mA. I'm not an expert in this area but it's highly possible scenario. Tweaking the system brings lots of good things to us but in the other side, there could be some
side effect.
If you want to verify this theory, you can just compare the non tweaked rom versus tweaked Rom.
Be sure that you don't run any battery saver apps on non tweaked rom to measure it correctly.
Attached is my last screenshot yesterday after I removed the battery saver app. Currently I'm using Calk's Stock Rom FC07 (non tweaked version). Based on my test, the battery last longer than when battery save app installed and running.

Cool I didn't know that would be an issue. Well I'll try that thanks for help

Well the best kernel for battery and flawless performance for me is Eugene's streamline.Give it a try.

3% in half an hr is nothing. all usage is subjective and based on each individual users habits with their device.

Not a new rom. Been faithful with juggs ever since it came out. But have been trying a few kernals on the way and alway went back to fauxs. My usage has been moderate to light with little screen on time, and just a little web browsing and emails. Although I did just add a few widgets to my home screens. I've just noticed this sudden increase in power consumption after eugenes stock gb launcher.
Please don't make me go back to tw
Edit: 39% left with 1 hr, 40 mins of screen on time. Total of 4 hrs, 43 mins so far

Sent from my SGH-T989 using xda premium

You might have an app that is draining your battery. Check your battery usage and see if there is an app causing it.

Google and download betterbatterystats to see if a rogue app is making your phone not sleep. If there are none, then you are not having any battery issues.

You guys need to try the new UCLA port. I'm at 1 day 10 hours with 27% battery left.. Screen on time is at 3 hours so far. Auto sync, 4g data, and everything else has been constantly running the entire time. I don't turn anything off. I use my phone for the same things every day, and have never got over 15 hours. This ROM is insane.

Hot phone after switching kernel

First I like to point out that this is my first android phone, coming from Apple. So I'm fairly new to this phone moding thing.
Well as the tittle suggest, my phone feels kinda hot after
installing Faux's kernel. I when to sleep with the phone at about 90%~ And 45 mins on battery. Woke up 5 hrs later with battery at 24% and 4h 30 mins until empty. I know that I need to give it time for the system to rebuilt a cache for me to see true battery savings like many of you are posting.
Is this a common thing when switching from a stock kernel? Or will the phone always feels hot?

It shouldn't be running hot nor be draining that much idle, i'm assuming you have a rogue app. Look at your battery stats, your phone should only be awake while the screen is on, unless listening to music or something. If the awake bar is solid across that's no good. Means the phone is not entering sleep mode. Ironically mine just did this today lol, it happens from time to time. Try a simple reboot and then let the phone sit idle and see if it sleeps via the battery menu in settings. If it is, then good your set. If not, get better battery stats from the play store and it will tell you exactly what is running and keeping your phone awake.
Edit: here's a pic of my battery stats today where something went rogue and kept the phone awake, notice the solid awake bar until I rebooted and then it functioned properly where only awake with screen n, and a bit with the screen of as I was streaming pandora. This is what you do NOT want your battery stats to look like. Like I said, if it does, try a simple reboot

Edit 2: the bottom of the phone will feel a bit warm when being used, especially with high brightness, gps, downloading, games etc. This is normal as the cpu is located there. If it's hot or warm while idle, that's not the norm.

Thanks. But I'm suspecting that is the ROM I was using. I'm going to do a full restore and reflash everything.

Its not the rom..thats impossible! Its has to be the kernel go get ktoonz 9-23 and u will be fine and u can oc to 2.1

Well I was on the Faux's kernel, with the High on Android ROM. I reset everything back to stock ROM / stock kernal, facotry reset and the phone no longer feels hot. But my Play store is not connecting(guess when I flash the gapps it'll come back).
The ktoonz kernel was the first one i tried but it felt kinda laggy and was the reason why I switch to Faux's. Now I'm looking for another ICS ROM that is not all crazy(I liked how simple the High on Android was), and I guess I'll give Ktoonz a try.
What app is good to use with the Ktoonz kernel? Battery manage wise I like the GSM battery mod. I downloaded Better battery status but it never showed me anything on the screen(even after 15mins) like GSM did.

I used to run fauxs and my phone would run hot.. After a month there were no new updates and figure he stopped development.
Went to kt and couldn't be happier. Can oc more, under volt more my phone couldn't be faster and never overhears unless I'm playing a game for a whole.
Kt also is actively developing with a new release every 5-10 days and he is very active in troubleshooting

Not only was my phone overheating, but the battery was also draining like crazy. In about 30 mins of the phone just being idle I lost about 6-8% of the battery life.

So I switched to The Ariel ROM and the Ktoonz kernel. So far no problems. Going to see how battery life is on the default kernel settings before messing around with voltage. All I have changed so far is the I/O, the governor, and the screen off max mhz to 486

Using the 9-23 build, LTE disabled on Bell JB leak LI3 (only options are GSM only or WCDMA only... I've tried both, both get me 2Mbps speed when LTE gets me 30Mbps in Kingston)..... my phone drains faster than it charges on a USB port, or in a car, and takes ALL night to get to get 100%.
I unplug, eat breakfast, and I'm down to 86% this morning with a piping hot phone. I can feel it through my work uniform.
Lame.
Very lame. Bell won't help. Samsung won't help.
Bell: Disable LTE, its a known issue.
Samsung: It has to do with Bells LTE towers. It's your provider, contact them.

I get these types of problems constantly with my S2 (Bell, completely stock). Recently I installed CPU Spy from the play store and low and behold the phone is not going to deep sleep. Sometimes the processor will lock at 1.2Ghz and pretty much burn a hole in my pocket. A reboot fixes it, temporarily.
I advise you to install CPU spy (free) and check out what the processor is doing over time. Could be a app causing the phone to do this as well
