Worst battery life ever

was today with:
2.6.35.4_SVS-925mV_BFS_AXI_720p_1113MHz_082710
and
update-cm-6.0.0-N1-signed.zip
with phone idling all day, battery went dead and phone shut off within 8 hours of full charge... wtf?!?

I've also noticed that with the latest CM's battery life is an issue for me. Ive got KoR roms to last almost two full days but cm is dead within 20 hours.

My battery life has changed as well and I now have to keep my travel charger and car charger with me at all times or suffer with a dead phone.

i had been running rc3 with the 8-19 kernel, and my battery life was similar to stock, but the combination of latest CM and wildmonks are just killing me... i think im going to go back to rc3 with the 8-19 kernel.

Check the active processes. You can't drain the battery in 8 hours unless you have a process stuck, using 100% CPU constantly (possibly Exchange?).

good thought, but im not an exchange user... i cant seem to isolate the issue. im going to do a full wipe and try stock to see if maybe i have a bad battery.

People with battery life issues should try Enom's ROM with a wildmonks kernel. I'm 18 hours in of a full charge and I'm at 76%. That's normal use with full screen brightness, wifi and gps, quite a few background updating apps, etc.

Over 50% of power usage should be the display under even moderate usage.
With wifi, push, and poll active, the battery drop per hour with the screen off should be less than 1%.
If it's higher than that, you need to find the rogue process or get rid of an automatic task killer.

Display is most of my usage with over 50% every time. I have one app that auto updates in the background, Twitter, and thats every half hour. I do have 3g on but with wireless on most of the time. GPS, Autosync, and Auto-Brightness is on. I play one game twice a day, World War, once in the morning, once at night, but both times are usually on the charger.
Now that I think about it, Im a part of latitude but maps/latitude never consume battery according the about>battery.
Either way CM6 full charge starting at 4am, with light-moderate use, will be dead at like 5pm. I can go almost 2 days on a single charge of KoR rom. Enoms rom I have tried and lasts a full day +some...

I have the same issue and have had it since RC2. I can deal with it since I have the desktop dock at work, the car dock, and two wall chargers at home. The drain is pretty noticeable -- after about 30 minutes of the phone being off the charger and left alone with screen off, the battery charge is at 94% with "Display" using 65% of that. Wifi/BT/GPS off.
Like I said, it's not a big deal right now because I have chargers everywhere, but it's really annoying. I'm still searching for the fix, but if I can't find it, back to MCR for me.

I tried CM for 1 week and I must say the extra glitters is not worth the poor battery life., only lasted 1 day if used moderately. I just switched back to FRF91 Stock Rom today, lasts me 2days if used moderately. Longivity of the battery is another long term concern people should think about. I still miss my modded dialpad with big buttons, cool trackball colors and many more, CM is such a TEASE!

What kind of battery life are people getting with Pershoot's latest? It's undervolted, so it should do pretty well.

Tried Enom? I've seen zero difference in battery life, perhaps slightly better, since switching to it from stock Froyo on my N1.

In the battery use screen, what's draining the battery with the screen off? Let the phone drain like 10% with the screen off the entire time after unplugging.

several recent nighties and cm6.0.0 seem to have something broken.. Four hours of standby after full charge and the battery level already @ 83%.
cell standby 32%; idle 29%; display (wtf was turned off all the time) 28%.
Drains twice as fast compared to older CM roms..

The LEDs are also considered the Display by the battery meter.
Still, 17% in four hours is enormous. I guess I'll have to hold off on CM6 until they sort this out.

Dicks! 4% battery drain in one hour with almost no use, and that's after flashing pershoot's undervolted kernel. No way.
I'm going to try wildmonk's kernel now. :/

[Q] What's your Battery Life after EB01

I hear constant griping about battery life since EB01. So I was curious what amount of time are people getting on their full charge? I am getting about 13hours. Definitely less than before but tolerable. Have done all the battery wiping techniques. Why is there such a different between users?

I get about 15 hours of good use out of it since updating to EB01. this is with moderate use.

After about 18 hours, I'm generally ~1/3rd the battery left. I'd say a large part of the variance is how we actually use it. I think it'd be good if at the end of the day, you wrote down the unplugged time, the % remaining, the % of the top several items in battery use, as WELL as the actually amount of time for each of them. Right now 'display' has used 41% of my battery, but only been on for 11m45s (the phone has been unplugged for 6h45m, with 72% remaining).
Without the full context, it's extremely hard to actually have any idea what's going on (terms like 'light'/'heavy' use are totally meaningless). One person that regularly gets 2 days (depending on my use I can easily), vs a person that can barely make it through a day... that doesn't mean that the latter person's phone is messed up, they might stream LOTS of music & videos, while the other leaves theirs in airplane mode half the time.
Edit: I'm on SC 2.1, with GPS, all location services, WiFi, and auto rotate off. I leave sync on always, and I'm nearly to 9 hours now... with still 72% remaining... and just dropped to 71%!

Horrible... with vanilla froyo v5 it was amazing, but every other has been almost intolerable. Sc2.4,blackhole,gingerbread... I've tried all of them, for several batt cycles. On second day of miui, ill report in a few days. I've always flashed at full battle, never have GPS or wifi on, turn sync off a lot, and always have my screen turned down. I'm at around 10 ta 13% drain an hour

I know I said I was getting 12-13 hours. Well I did the battery script download and am now at 63% after 12 hours. I would highly recommend giving it a try. It didn't seem to do anything the first day. More the second day couldn't be happier.

SC2.2 nonvoodoo with no power management apps. Overnight off charger for 8 hours battery loss is about 3%. My typical numbers starting from a full charge averaged below.
Screen 3.5 hours.
Calls 45min.
Gmail sync avg. 20 emails.
SMS avg. 30
TWS +/- 4%
BW weather updates hourly.
Those numbers usually get me to about 15-20% battery. So with that usage it can be done in one day or I have also stretched that usage over 2 days.
good day.

Anybody try any of the battery saver apps like super power or juice defender? I have tried juice defender but it wasn't toggling data so now I'm trying superpower & it toggles fine but keeps the phone in partial wake according to spare parts so I wonder if there's any real benefit... I'm now down to 11% after 10 hrs off the charge.

After trying the battery wipe script, and several battery cycles, I'm about 1/3 less battery life than I was on DL09. I'm hoping once we get source, we can get a LV optimized kernel to get it back to where it was.

I used Juice Defender back on DL05, but found that it made my battery run down faster AND it'd cause many of my apps to update inconsistently (using both the default setting, as well as others). Even after disabling, and then uninstalling it, my sync settings were screwed up until I flashed EB01.
I'm not going to trust any of those apps again... thinks work better if you just find apps that aren't power hogs (such as constantly polling the network!).

Back on DL09 SC 0.9, with Adrynalyne's undervolted Voodoo kernel, I could get two days with light usage without trying very hard. Now on EB01 SC 2.4, I struggle to make a full day. Not sure if the drain can be fixed with working kernel source code or not, but I imagine it will help a lot. Until then, I can't bring myself to go back to Eclair again, so for the moment I'm putting up with the poorer battery life and lack of Voodoo sound.

Battery, it's now time to exchange you!

I'm so giddy right now. I've ordered an OEM battery for my Vibrant, and i should be getting it any day now. The reason for me ordering a new battery is limited usage time. Lately when flashing any ROM, I make sure It is at 100% charged. I will normally get about 4.5 or less hours of usage - using a little app named 'Battery Left'.
I don't use a task killer. Ever. I know this has some controversy signed to this, but the Android OS is engineered without issue regarding this.
I Use WiFi whenever I can (uses a fraction of the power 3G radios use). When I CAN'T use WiFi, I make sure it's turned off so it's not wasting power scanning for hotspots.
I make sure GPS is off whenever i'm not using it.
I set display timeout to 30 seconds, set brightness to Auto, or manual and the lowest. Little trick, if Brightness is on manual, you can adjust it on the fly by swiping left or right across the task bar.
I let the battery TOTALLY discharge at least once (twice is better) and then charge to full. This doesn't condition the battery, this just calibrates the battery metering software, so that it knows for sure where zero is, making the metering more accurate.
I try to use a darker colored wallpaper, blacks and reds and deep greens and blues use less power than lighter tones, and white is the worst.
I get a half-day out of my rooted Vibrant on T-Mobile, and I actually use it as a phone (amazing huh?), PDA, game machine, ebook reader, etc, it's not just in my pocket on standby. Battery life has nothing to do with it being unlocked/rooted.
I understand the biggest reason why people think THEIR particular smartphone has some sort of battery problem: They just got it, and are using the hell out of it. We tend to not set it down in the first few days/weeks, we're always fiddling with it, showing it to our friends and co-workers, etc. Once the new and shiny wears off, and we settle into more "normal" usage patterns, we start noticing that we get a lot more battery life out of the device. Some people think that the battery is now "broken in", but the truth is, the USER is broken in.
Some of my POWER hungry apps I use on a daily basis is 'SportsTracker' which I use riding my bicycle to and from work (7.3 miles one way). SportsTrack uses my GPS and tracks my ride in REAL time. It sends a link to Facebook and Twitter, where my friends, and family can watch me go. This app uses about 17% of my battery - one way. So, at the end of the day, just using SportsTracker it uses at least 35% of my battery.
Speaking to the heavy users, how many hours do you normally get using your Vibrant?

With 20-30 calls a day, 20-50 texts, dozen or so emails and listening to music and just geeking on the phone Axura 30 hrs before it is 15% Trigger 24 hrs before 15%, but then, that's how it works for me. Since I got rid of stock roms, I have had ZERO battery problems, I only use Task manager. Deleted all the bloat and I have screen set to 50%. Battery is no longer an issue

With Bionyx 1.3 I let the phone sit idle (exchange email running in the background though) from 8AM and till 4PM it took only 15%
Skype+music+movie for around 1 hours and it's down 15% more (now 70%)
I guess it'll last 1.5 day normal use and 2 days idle use

That's a great battery life. My bionix eats more battery on almost the same usage. I have around 76 user apps installed and some bloater. One thing I have noticed using system panel is when I sleep, my phone sleeps with me and uses an average of 1% battery per hour. Is that good? I still I think im not getting optimal battery life when im actually using the phone.

You guys think that's good battery life? Nah, this is good battery life.

I always got 20-30hours a charge with most of the Bionix roms. However with Bionox 1.3 I struggle to get more than 12 hours with the same usage. I did notice that new app BLN (using your soft keys as notifications) was reported on some other roms as a battery drainer, so I have uninstalled via Titanium. I will report back tomorrow if that is the issue. I still use KA5 modem, so that part has always been a constant

Weird. I'm on 1.3 as well. I'm 15 hours into my charge with normal usage on 3G/WiFi and I've got 25% left.

I'm 15hrs in running Bionix-v 1.2 and i have 42% left. That's with GPS on all day....phone in pocket from unplugging to about 3:30pm. Then only light use.
Days that I use heavily I'll have to plug in around 4pm. I'm not too happy with my battery life. I love my phone...but my old iPhone 3G had top notch battery life! lasting 3 days without charging.
Is it not weird how these times fluctuate so much between users?
Will the new Galaxy S 4G battery fit in our phones? Or will it even be worth it?

Do you have the superpower app? It saves my battery big time when phone is sleeping.

I ordered a batter charger, two spare regular batteries and one spare extended battery last month for my vibrant.
Now I keep a spare charged battery in my pocket and I no longer have to plug my phone in anywhere I go. I just swap batteries and put the dead one on the charger when I get back home.
If I am going to be away from home for more than 24 hours then I put in the extended battery which gives me about 2 days worth of use.
Its a bit of a pain to have to be down for a minute when the battery is dying, but I am more content using the phone this way since I can now keep it with me instead of leaving it upstairs or on my office desk to charge.

My phone is on the stock KA6 kies and from 8-8:30 it is off the charger on 3G. When I get to work it is on WIFI with WIFI Calling(no signal indoors) from 8:30-12:00 and goes back on 3G. then at 12:30 it goes back on WIFI(calling) and sits like that till 5:00. Usage during that time, some email viewing, 10 txt or so, 5 min phone calls and that is it!! from full charge at 8am to 5 pm I'll be at 45-50% battery left and what you read above is all I do with it all day. Battery life is horrible. Not much I can do(unless someone has an idea to fix the issue) as I need WIFI calling otherwise why have a cell phone?

Food for thought

So 16 hours with 3G and WiFi Calling on all the time...on the STOCK Samsung crap? Thats pretty awesome man. WiFi calling is a HUGE drain. Spend the $2 on an app called SystemPanel. It will tell you exactly what is taking up CPU Cycles which, of course, uses battery.
I go 24 hours on a charge with routine use. Granted, everyone's use is different. But I got two days with the KA7 modem on Bionix V. I see no difference with 1.3 (haven't used it enough to tell). Granted, I had WiFi Calling frozen and was on EDGE most of the time and turned on WiFi when I needed it. I've observed WiFi Calling using excessive CPU cycles when it isn't even on. Its pretty poorly coded. I recommend freezing wifi calling when you aren't using it.

SyndicateROM Frozen (EB13) - Battery Life Thread

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.

Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.

I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.

I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours

With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.

1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,

I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.

Comparing gingerbread battery life...

I wanted to start a new thread comparing which GB roms have the best battery life....

I'm running CM7 and battery life isn't that great.

^THANKS^^ battery life on Simply honey 3.8 was pretty good....

This thread is a great idea, but let's put some numbers down rather then, "I get really good battery life!"
CM7: I get about 13 - 15 hours with minimal use on edge network.
Minimal use for me is about 2 or 3 phone calls about 30 seconds to a minute each. Less then ten text messages, very little to no web surfing. Check weather, look at news headlines.

Well, i have only tried CM7 and MIUI, wich is CM7 based, and to be honest, battery life is the reason that i came back to Froyo...just terrible batery life...i can't be charging my phone every 5-6 hours. On Froyo im using Super DragonModz on Project V, and i havent charged my phone in two days, and still its @ 25%...average/min use. Until GB gets good battery life, i might not be using another GB rom as a daily driver...

My battery just went down 2% on a 40 second phone call with my lady. Simply honey. It drains bad. This is my 4th cycle.

thats odd...have you tried doing a battery calibration....
anyways i get 10 hours on Revolution rom 2.0 with moderate use
moderate use -check xda couple times ,on h network always with background data ,some texting,3-4 30 second calls and ocing to 1.2ghz

Yea. I calibrated. I thought it was just a bad flash but after multiple flashes I had the same result.

Blitzkrieg 18 to 20hrs moderate use 3-4 hrs screen time one.
Pretty good if u ask me.
Screenie attached 30% batt left. Calibrated two days ago.

With every type of battery caliberation it takes a few cycles of charges for it to actually work. I use sgs tools and apply script and that deletes battery bin files. But doing that is not gonna take effect right away i hope u guys know that.
Im on cm7 and my battery usage is better then i expected. With me using either google music or Audio galaxy streaming for a 8 hour workshift and texting and websurfing during a lunchbreak and when that shift is done i still have about 20-to 30 % left sometimes as high as 40% But if im not streaming music and just doing normal things like playing cut the rope and web surfing and emailing, texing etc i can go on all day with out a charge. So maybe u guys have a bad battery???

Simply honey 3.8 was eating up 3-4% per hour just idling and much more when actually bring used. Back to Trigger.

simply honey 3.8 has really good battery life i get 19 hours moderate use with kb5 modem and OC'ed to 1.2 ghz

On Revolution Rom, I can get 16-17 hours of heavy use, which is flashing a new build almost every hour, going crazy on the battery life testing. But people have reported about 24 hours of battery with moderate use.

Asgard 3.0 and 3.1 Both are giving me 13-15 hours with moderate use gaming (my kid 45min-1 hour) internet use, tweeting, email and moderate to heavy phone use (20-40 calls per day) and 1 hour of tunein radio.

I got an average of 15 hours on Blitzkreig with 15-20 short (under 3 minute ) calls, 35-40 texts and an hour or so surfing.... plus a little gaming. I am at 5 hours on Asgard 3.1 and 78% battery.

I am running the Revolution Rom RC1 also and I'm getting about the same battery life. It's about the best that I have gotten on my phone, Bionix Final 2.1 aside. Great job, keep up the good work Ali.

Revolution ROM's battery life is pretty good.
Can't compare with others since I've just started flashing GB roms now (I had tried MIUI before but back then the battery sucked so much it doesnt even count)

thanks for starting this thread, it was just what i was looking for.
i used CM7 awhile ago and the battery life was pretty terrible so i switched back to froyo. so now i was looking around again for reports of battery life now after a couple months of waiting, and looks like its still pretty bad. i guess im still sticking with froyo.
but hey i still appreciate all the work the devs do to bring GB to the vibrant

with all the MINIMUM use or HEAVY use
can you guys post the screen on time with it to shows how heavy/ minimum you use....

I've been using Blitzkrieg for a week or so and at first it seemed really good but the last few days it has been draining fast for some reason. I also have had it reboot a couple of times while on the phone the last 2 days. I'm not sure if it's related....
