Battery problems? Google lies?

So I found this great app that tells me how much life I have left on my battery. I find that with my phone I can hardly go pass 16 hours with MODERATE use yet everyone here is bragging about easily passing 30hrs with HEAVY use. So I'm asking you guys, to please, download this app called BatteryTime Lite and post your pics or info here. Lets compare the results. Remember to set the level to 100% as shown in my pic below..
Also I herd the P/N might be related, mine is 99HKE002-00 F ..Guessing F means Failure.

Are you using Cyanogen's ROM???

No, stock. Why you ask?

i read somewhere that Stock and Cyanogen's ROM have display consuming a lot of battery... its fixed on enomther's and modaco's desire port...
On Cyanogen and Stock, Display consumes ~60% battery while on Enomther's and MoDaCo's desire port, display consumes 15~20% battery...

Thats what I herd too..thats why I'm also calling google a lier about saying this thing lasts 20hours with audio playback.
I'm curious, do they see a big improvement in battery when the display using 15-20% battery or its just numbers that were out a place to begin with?

I have identical figures. That combined with picking the N1 from a list says to me that these are just database figures rather than real world ones for your handset.

Root your phone and then install cyanogenmod and one of the under volted kernels. I usually get 24 - 30 hours battery life.

I just ran a test. I left the mp3 player on all night turn all the way on repeat. SO far after 8hrs of playing I was at 52%. If I'm correct, I just might be able to hit 18hrs...MMMM

No problems at all? no 3g issues?, battery only lasting a day or half? or touch screen issues?

Ok after 100% charge..the app is telling me that my phone will last 10hr:48min with moderate use....anyone thinking that the F on my P/N might mean battery sucker..

i have the exact same numbers as you. if you choose other instead of the phone type it asks you to enter your battery's info so it sounds like it only goes by the type of battery anyway. Not actual usage specific to your phone

My phone ends in an F as well. My battery life SUCKS right now. I have tried everything. The weird thing is it was good until I rooted my phone and applied Cyanogen rom. I've tried .2 and .3 for the Cyan rom's, all with bad battery life. I've tried wiping batterystats, fulling draining battery then recharging, task killer to wipe anything in the background, I even have a 2nd battery. No luck. I've also tried the undervolted kernal, but I didn't really notice a difference with it. (Only tried it for about a day so)
Bottom line though, something is going on. Something (I suspect with Cyan's roms) is killing battery life for some of us. I just wish I could figure out what it is.

Any chance you're using Weatherbug or Weatherbug elite (based on your SS)? After installing weatherbug and using the widget I got absolutely ABYSMAL battery life. I've purchased several other weather widgets and none had the effect that Weatherbug did for some reason. I removed it and battery life is back to normal again (moderate use and plenty of battery at the end of the day).

How long your battery lasts definitely depends on the apps youre using, I use my phone a lot, probably more than the average user, although i dont make many calls. My phone will easily last from when I leave my house around 530am till 11pm or so when I go to bed. I do use a task manager to kill stuff I dont need running every once in a while, I think it really just depends on how you use it. I use it for a lot of texting, surfing and news, and Pandora at work. I use wifi when im at home although ive never noticed it eating my battery. Yesterday I was playing Pandora over bluetooth on 3G for a little over 3 hours and it only took 5% of my battery. Im on Cyanogen 5.0.5.3, if that matters. With all that said I rarely go all day without charging it, I usually plug it in a bit at work and plug it in when I get home, but if I dont for whatever reason it easily lasts my whole day.

Battery Life

Hungry Man ~
Lately I've been running the latest update of the same ROM (Nonsensikal Froyo - now 15.2) without any CPU apps (no o/c'ing through script either), no autokiller, no battery tweaks (just Juice Plotter) only 1 widget (Fancy Widget Pro), JIT enabled, VM heap @32, compcache @18 (default) and depending on which app I look at, TiB or RE, I have +/-110mb of free RAM, very minimal apps. Also, I upgraded to CFSv9. I even bought a Seidio Innocell 1750mh extended life battery. I recalibrate my battery after flashes ....
Oh yeah, a little more info, I am not a power user, just an average user with poor to ok reception, I tend to use wireless at my house b/c reception out here in the woods ain't good, but turn it off when not needed. I use airplane mode during sleeping hours as well. The max of my battery usage is Display, then And OS.
Ok, now the question ..... If I don't use airplane mode, I get maaaaaay-be 6-8 hours of average phone usage, usually less !!
What finally broke me to PM you now is that (i recently put numbers on my battery icon) while typing a text message earlier (a few minutes tops, not on wireless) I watched my battery click down from 50 to 48 !!!
When I charge my phone full & I easily lose 10% in half an hour (I've tried this with SetCPU, JD, CBT, Super Power, CPUBoost Lite - I think you get the gist) ... and not including airplane mode, I NEVER get more than 6-8 hours of battery life !!!
Is there any knowledge that you can give me on this issue or have I pretty much exhausted my options ? I am this PM short of resigning to crappy battery life
Many Thanks for your time ~
Matt

What does the phone/Spare Parts say is using all the battery? Have you tried flashing and then using the phone without installing apps (other than the essentials?) Are you leaving the phone idle, screen off, and noticing the same big drop?
You could try going to stock for a bit to see if it improves...or trying a different ROM. Maybe you have a dud battery?
Edit: Sorry, you may have meant this to be directed at someone specifically.

Just an observation. If you're not using anything to overclock the phone maybe the battery life would be better if you at least underclock it. I suggest Conap's CPUBoost Lite, free on the market and here. Just set the minimum frequency to 245760 (my suggestion), and I currently have the screen off Minimum to 19200 and the screen off Maximum to 480000.
Also, I used to use Juice Plotter. I theorized that maybe Juice Plotter wasn't great for my battery itself.

I noticed the same thing when I used Juice Plotter. I got significantly less battery life when i had it. Try deleting Juice Plotter and see if you get more life out of your battery.

well you've noted your in a poor coverage area, and that is your problem, nothing can completely fix other than moving, but you may want to research flashing a new radio, becareful and check your md5 hash sums

Actually, the Verizon Network Extender can definitely help without moving. http://www.verizonwireless.com/b2c/store/accessory?action=gotoFemtocell
It's $250, but probably a lot cheaper than moving, and it should help with battery life. It does with me - I get 24-32 hours on a 1750 battery, with WiFi on all of the time (I have the old, non-3G extender.)

I'm running Tazz Froyo and get a minimum of 24 hrs on stock battery. I would try changing roms.

Battery life on my eris was never good, that's why you buy a extended battery. I have the biggest one that they have on amazon and my battery can last for five days with average use

so my battery has been draining really fast too, but my question is does the battery recalibration work? some people have said their battery drops even faster but is that only the first time?
PS. ive been on xtrrom for awhile now (like a month and a half) and it just started dropping. spare parts says android system is greater than the rest, if that helps

Yes, it works if you do it propely. Charge phone to 100%, boot into recovery, wipe battery stats, reboot phone. Use your phone as normal until the battery is fully discharged and it shuts the phone off. I sometimes try to turn it back on also just to make sure it is all the way dead. Plug your phone in to charge it, walk away, don't touch it until it is 100% charged. Turn your phone on and use it as normal. It sometimes will take a few times charging it to see a difference. If I missed anything or mistyped anything some one correct me please lol

I'm just gonna say...(Batt issues)

Before I was a behavioral therapist I worked for a small (lol) company called Applied Materials. And there I worked as a project manager. And what I learned there was the importance of following procedure, something most here seem to fail doing. I know I'm not the only one tired of seeing at least 2-3 threads a day pop up complaining how adryns or blah blahs rom is giving you horrible battery life. Have you stopped and thought for a second that it may have something to do on your part? Let me rephrase that, it is something to do with you. There are procedures before flashing...for example, flashing on a full charge is ALWAYS recommended. Second, wipe wipe and wipe again. I hope you don't wipe your ass the same way you do your phone. You stop to think for a second that flashing two themes a day isn't going to f things up with your battery if you're not following proper protocol? Why is it some people don't have issues and some do? It's simple, you f'd it up.

And for the record, the reason I posted this is to stress the importance of following the rules, bc when there really is an issue, it's like "the boy who cried wolf". We don't know which is legit and the other is just some kid too hyped to get that blackhole or superclean and cuts corners.

This thread drained my battery real bad.

The fascinate is proven to get better battery life then the droid amoung many other androids. I get maybe 16 hours of heavy use. I've been on this forum all day running superclean 2.1 with voodoo and still have 37% left...yeah that's some ****ty battery life for ya lol
Edit: maybe the majority of us getting around 15+ hours are just on some really good dope.

Droid? Which droid? Certainly not the Droid X, I had one and battery life was way better. I dont know anybody that gets more than 10 hours on heavy use. Sure you can get more if you dont actually use your phone as a phone.

Lmfao...really? Then why is my cousin who has an x charging his phone while im sitting here on his couch still posting. Before you post again take a peek...i've been trollon this forum for 12 hours now.

I followed everything to a T the second time around. My first time flashing superclean I was getting less than stellar battery life. Second time around I wiped data, cache, dalvik, and battery stats multiple times while on a full charge.
I've had my phone off the charger for 13 hours now and I am at ~60%. I haven't used it as heavy as normal, but even under heavy load I am getting much better battery than my first time around.

In "16 hours of heavy use", how much of that time was your screen active? You can look in Settings -> About -> Battery Use -> Display. "Heavy use" is a fairly imprecise term, since what one person might consider heavy use might be 'fairly light' to another.

I agree with your post, thought. Every time a new rom is released, the next several days are filled with complaints about the battery life. If you follow the procedure for resyncing the battery stats, your battery life will be back.

I get good battery life...so this isn't a fact for me.
The most important thing to keep in mind is battery life is SUBJECTIVE, as are the terms used to define usage (including "good" and "crap" as in the above). What one person considers "light/medium" use might be "heavy" use for someone else, and vice versa.

For me battery life on eb01 is great as long as gps isn't enabled in the pull down shade. When that is on the phone doesn't sleep even if gps is never showing active in the status bar.

Not percentage, but time.
My Fascinate, currently, has been unplugged for 22 hours. Light/medium/heavy use is all completely and totally relative and opinionated terms. The amount of 'Time on' for the screen is a fair bit better way to show the use than just the meaningless 'heavy' & friends terms *. I've had my screen on for 55 minutes total, during those 22 hours, and am down to 42% battery life remaining. I wouldn't call the use I'd done 'heavy use', but someone else might consider that about as much use as they've given their phone in a WEEK!
I find my battery life is decent, but by no means amazing (I generally always make it through a day, 2 with light usage).
* Even then, it's a fair bit different if the time was spent looking at a single active pixel on the screen, vs playing with an augmented reality app that keeps the GPS, camera+flash, and wifi/3G constantly going, while also burning huge amounts of cycles on both the GPU and CPU... but one step at a time.

In my case it's mostly due to the fact that the phone never sleeps if GPS is enabled. When the phone doesn't sleep, it eats battery at an alarming rate even just sitting in your pocket. Once GPS is disabled in the notification shade, battery life is more in line with DL09. I'll be happy once we get some custom kernels, as a LV kernel seems to help my device a bit, but battery life isn't so bad anymore as to cause me to flash back to DL09.

consistently mediocre battery life even after calibration and undervolt

I just can't seem to crack the battery life conondrum. I've calibrated (charge to 100%, wipe stats, then full cycle).
If I'm listening to music its consistently I'm sucking ~10% an hour, if idling ~4-5%. Which means I'm getting around same battery life as my old nexus one – mediocre, I end a working day with around 30-40%. If I want to go out after work i have to remind myself to charge during the day...
Right now I'm even running a mild setcpu undervolt (with faux123 kernel) and profile (screenoff max cpu 600mhz) but seeing not much improvement if any.
I am on gingerbread AT&T radio so thats not it either... any tips aside from 'use juice defender' (which I don't want to do as I want always on data instant push etc., I know juice defender basically shuts your data radio off)?
Note this is the same with stock gingerbread as well as the ROM and kernel I'm currently on (redpill, faux123 kernel)

I've done everything you have and i'm on a Bell Atrix....i have been looking into this for about a week or more and i just can't crack it either!!! it's driving me nuts and i have spent sooo many hours googling, searching xda and other sites and have tested MANY different methods and still can't seem to figure it out. For me i know its the phone idle...but what it is i can't tell, i have SystemPanel monitoring as as well as watchdog which i alternate with. Flashed the battery calibration fix and calibrated the meter blah blah blah....driving me nuts and i know its not a faulty battery because before i unlocked and flashed 2.3.4 i could get about 30 hours with heavy to moderate use!!!
For the love of god i wish a team of dev's would look into this!!!!!!!!

Honestly none of the faux kernels worked for me... Try gobstopper, stock kernel with watchdog was the only combo to give me good battery life. Not to mention lock sounds works properly, and its fast. All bell users should use it. Seriously... 19+ hours worth moderate usage.
phone idle is still high but it seems to be a slow drain.
Sent from my MB860 using XDA App

a.) not an option for me, AT&T phone
b.) I'm not seeing faux's kernel do any worse than stock kernel, I don't think its the kernel?
c.) yeah I tried system monitor as well, the highest process was opera at 3%.... 3 lousy percent lol

1. Calibrate your battery again (I have posted a guide in the General section)
2. Flash a kernel which allows overclocking, install SetCpu, add battery saving profiles (downclock to 500mhz on screen off, downclock to 800 mhz when battery less than 30%, downclock to 800mhz if temperature higher than 50C)
3. Freeze all MotoBlur bloatware (there's a guide in the general section)
4. Disable data and wifi unless you need it
5. Install Watchdog and set it up according to instructions I provided in my calibration thread.

It's not the Atrix'es fault, its the brutal truth with all modern smartphones.

The people in this thread have listed all known steps to improving battery life.
If you really follow all of these guidelines and have bad battery life, you might want to try a battery replacement.
If you are sure your battery is not the problem, you might also want to try a couple of custom roms. Who knows maybe you will get lucky with one of them.

Is there any way to log off from motoblur once you are in so you can stay offline? Of course any connection that gets cut will increase battery life.

I don't understand all these battery life problems. Its got to be an app you are installing or your battery is buggered!
Admittedly when I first installed 2.3.4 OTA, battery life dropped like a stone, but I drained it flat, and then charged it up again and its been fine ever since.
I'm running on stock 2.3.4 without root, and I have quite a lot going on (IM's/Facebook/Twitter) and I can last well over a day and a half with moderate use, this includes sms and calls.

Battery life is a very subjective issue. One person might be fine with the phone, while the other person will say battery life is terrible with the very same phone.
Besides the obvious drainage problems, it all depends on how you use the phone.

Honestly the best thing that worked for me was turning off "Syncing".
I currently have 3G on, BT on, ETC...
Syncing in the background killed my battery life. Now I usually make it through the day without the need for a top-off...

Im in stock gingerbread and battery life is definitely worse than on stock 2.2.2 and and im basically running the same Apps. I am a heavy user and I used to drop 10% per hour. Switch on at 7am and by 5pm I was changing battery. Now I am switching around 3pm.
That's why I have 3 batteries!
I still think its better than nearly every other device I have owned but that nay be because battery is larger. I dont know why they don't design to put in 2400 mah batteries (my treo 650 had one!).

The treo 650 also had a thickness double that of the Atrix .

The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do. This actually does damage to your battery by using up valuable charging cycles, all while giving a fraction of battery life and performance.
Now, you might be saying uh-oh, I’ve already re-calibrated my battery! What do I do?!
Well here’s your answer. Use your phone like normal. Yes, your battery and phone wont perform as good as it can for a while, but after a few days, you will notice that it starts doing better and better. Give it time, its trying to rebuild all those logs that you just deleted.

The batteries in your phone are high-capacity lithium-ion batteries. This kind of battery technology cannot be simply reset and “re-calibrated.” When you follow the steps to recalibrate your battery and delete the batterystats.bin file from your phone, you are getting rid of more than what you think… Stored inside that batterystats.bin file, your phone keeps detailed logs of the capacity of your battery and uses it on how it can be utilized more efficiently. By deleting this file, it basically wipes the phone’s memory on what the battery can really do.

This is the first time I am reading this sort of opinion, though I have read countless info on the subject.
If you want to make such a strong point, you better have source to back up your opinion (article, studies, other source of proof, etc).

These threads are all USELESS without NUMBERS.
Like another person with common sense already stated in this thread, you need to provide numbers.
GB has this improved tool (over 2.2) where you can see how your battery is wasting its juice. Watch those numbers for a few charges and then POST THEM TO COMPARE.
Saying your battery sucks without giving any numbers is like calling a color ugly.
(just in case someone misses the points, without numbers it's hard to compare, since it mainly becomes an opinion at that point)
P.S.- Please don't post "My battery lasts for over 9000 hours." and think that's enough info. Use your head.

Battery Life Rom REALLY Needed

Hello all
I have been roaming around XDA for a very long time now and I finally made an account because I simply cannot find an answer. I have a samsung vibrant and not the 4g nor can I upgrade(long story). I use my phone when I need it and i text alot. But lately my battery life hasn't been any good, I've tried reconditioning and the whole bit and nothing seems to give me my needed battery life. I am currently using ICS passion 13 RC1 and it works great, when Im not doing anything -.-; When I use it like for the internet or text a lot it drains. I got to 48% in 2 hours one time and thats with limited background processes. I know ALL about the keeping background proccesses and data using apps down so I hardly have any apps installed, which is very irritating at times, I dont even use the facebook app for that reason. I tried many different roms and it seemed Axura had done that best at one point but it was taken down or is no longer supported for whatever reason so I am now in search for a rom that can get me through the day. I text a lot and web browse occasionally. I dont have wifi so i cannot use that to save battery life while surfing so thats out. I would appreciate all the help and will try every rom if i have to lol XD
I appologize for the long message but I am so tired of hesitating to use my phone as a smart phone.

I get good battery life on the ICS Euphoria ROM. Your battery could be shot, you might try replacing it.

Any of the 2.3 or newer roms are going to get bad battery life. Fishmanmod's updating of Bionics has been very smooth and getting great battery life for me.

I find that battery life between 2.2 and ics is pretty much identical for me as long as there are no wakelocks preventing deep sleep. I'm currently on CM9 nightly w/ glitch kernel and deep idle enabled in nstools and have no battery life problems.
You could also look into getting an official 1800mah battery if you really need more juice

ICS Slim hands down the best.

Your issue is Passion. That ROM chews through battery worse than any I've ever used in the 2 years I've had my phone.

Its not just your Rom, I am on the CM9 nightly and noticed ICS ate my battery by noon today. I was down to 3% from 7am. Granted I am toying with it a bit more but I was still at work so I couldnt use it non stop and I wasnt even watching videos or listening to music on it. I have updated the kernel to SubZero 34 to see if that helps.

Chances are, your battery has lost some of its ability to hold a charge. I recommend buying a new OEM battery, chances are it'll increase your battery life by a good two or three hours.
So far, I haven't noticed a significant variation in battery use in various ROMs, I've found battery life to be more determined by the kernel.

On a side note, I destroyed my screen by stepping on it a few weeks ago. Ordered a new AMOLED screen (not the LCD knockoffs) and battery life did in crease by about 3-4 hours. Same OS, same battery.
So I think some excess drain could be caused by the screen, which might explain why some phones had such poor battery and others don't. I also no longer have the "graying/shadow" issue that plagues some of these phone.

So far ive had the best battery life with ICS passion RC2.1 and my 1800mah anker battery

Since flashing CM9 and then putting on the SubZero kernel (34) I did a full charge and decharge to test and got 12+ hours on it with my normal use. So I have to say SubZero kernel really helps out if you are on ICS.

I f you dont mind going back to a 2.2 rom I would suggest trying bionix 1.3.1 fishmanMod or Deranged9 fishmanMod alpha 1 both get awesome battery life especially when mixed with juice defender.

I was also using ICS Passion and noticed a significant degradation in available battery life. I have three batteries so I'm confident it was the From. Until then I had been using various Froyo rooms and all seemed to have better battery life than ICS. I personally felt it was more likely to be your kernel choice that would impact battery life. I just switched to the SLIM ICS from and I gave been very impressed with both the battery and the responsiveness. Same quadrant scores as Passion but it feels so much faster

I haven't taken the dive into ICS yet i may have to try that out.

If you r searching for nice n smooth rom try
[4.0.4][6-Apr]Slim ICS [3.2]

another thing you can do while flashing wipe battery stats only once....then reboot to normal drain your battery till it reaches 1% charge it full widout any interruption and when it reaches to 100% unplug it and do the calibration from any software available in the market I use Battery Calibration Professionals

repeat the process for atleast 3 days in a row and you will feel the difference..hit thanks if it helps

@OP ICS is simply not battery friendly. You're going to want to use froyo if battery life is that important to you.
Or you can build a battery friendly ICS rom and let us know how it all is

The later builds of Cyanogenmod9 I have been on the stock kernel and its going all day with moderate use without battery issues.

Bionix Fishman Mod is the first custom ROM I've ever installed on my phone and it's battery life is AWESOME. I recently added an 1800 mah battery and I've had 24+ hours on one charge with moderate to heavy use. The ROM itself is smooth as glass and no glitches to speak of.

Trying Bionix

I just installed bionix-V FishmanMod Final 3. Fingers crossed. I don't mind switching back to 2.2 as long as I have better battery. However I did notice when I reinstalled ICS before going to bionix that just factory, not even logging into the market. I got 1 day and 7 hours of battery life, granted I did not do much but text occasionally and some web browsing here and there. Is it possible that the android market is constantly checking on stuff or there is some data being proccessed constantly? I do live in an area where my signal is not great for 3g like 1-2 bars.

Alright so after about a day with the rom, I noticed it's just as bad. I am still getting battery drain and yes I have a new battery in so it is not that. I unplugged it from around noon, did alot of working on it with reflashes and little bits of texting and mostly just scrolling around the O.S. im now at 44%. its been about 5 - 6 hours.
Although I have been switching the battery between 2 phones and their battery meter is very different. like a 5% difference so that may be confusing it. Will update.
