[Q] Questions about improved battery life

So the day I bought my vibrant I had data issues. I talked a tmobile tech support guy and he helped me with my problem, great. But afterwards he asked me how I was liking my phone since he had one as well. We talked some about the phone and all, but then I asked about the battery life.
Heres the interesting part, he said after getting around 5 hours of use out of a full charge, he put the battery in the freezer over night (in a zip lock) and charge it afterwards. He claims to be getting a whole 24 his of battery with moderate use.
Is there any truth to this statement? I'm sure he was over exaggerating to some extant but he was a tech and I wanna take his word for it but dont want to try it lol.
Another thing is I want to know other ways to improve my battery life. I heard "training a battery" thrown around these forums, how do I do this?
I try to keep stupid services from running by going to settings>app>running services. Is this enough or is there a better way?
First post, hope it was a good one lol.

I hear ya man the battery is really bothering me too. It's basically dead by the time u get home, which is not good enough for me. I called T-Mobile and they are sending me another battery.
When I get the new battery I'll try the freezer thing.
Well, gotta go... battery is almost dead at this point. : (

when i got the phone i calibrated the battery like i did with my g1 with the cm releases. basically let the battery die completely then charge fully. don't know if that had any effect, but with how much i use my phone (moderate-light texting, browsing, gps when it works, no gaming) i could probably get through 2 full days. with playing some games i can still easily get a full day.
putting the battery in the freezer overnight shouldn't have any long term effect on the battery. it may improve your battery life very shortly because a colder battery holds it's charge better, but once it's heated up (or at regular idle temp in your phone) any small benefit you may have had is gone.

Try Juice Defender. It is working wonders for me. I am going on 8 hours of up time and I am at 75%. Normally I would be getting close to needing a charge.

What settings do you use? Do you use the default settings from the setup?

What the heck are you guys doing to kill your batteries?
I use my phone off/on all day off the charger at 6am and I turn it off and charge it at 11pm. Often I'm normally around 30-60% depending on the use through out the day.
Turn off what you don't need. I mean do you need wifi on all day? Do you need 3G on all day? I'm guessing you don't unless you are streaming video all day.

Yeah I don't get it, this phone has great battery life for me. I get about 20 hours out of a charge and I use it quite a bit.

Can you elaborate on your settings? I was thinking of installing this app and getting rid of the task killer since I'm getting very inconsistent battery usage each time after a full charge. Have you tried Ultimate Juice?

get rid of your task killer.

I think its just luck of the draw. When i first got my Vibrant i was getting at least 20 hours out of a charge. I had to exchange my phone due to a few annoying dead pixels and now im lucky to get 8 - 10 hours out of a charge. Everything is set up as it was on my original phone.

I just use the default settings at startup.

I have all widgets turned off, wifi off, gps off, brightness on minimum and a solid/static black wallpaper.
I use the phone for very few calls and very few txts... mostly use it for web browsing throught the day and some news apps - with a little paper toss mixed in.
I use my phone more than the average guy, but the usage is in line with my usage on my iphone and HD2. I know how to be gentle on the battery, but I still have to charge it when I get home from work.

My battery lasted 2 days the other day. Got down to 15 percent. It's very strange. I was using it but not very often maybe once every few hours. But I played some ff7 to demo to my friends, used the gps to get directions. Most importantly I started killing all nonessential apps with astro immediately after I stopped using them. I think this is what's prolonging my battery. Sure theyre not using anymore cpu cycles but they're still taking up ram, and that is a constant drain folks.

There is no difference in draw whether you are using 1K or 256 MB, the chip will always draw the same amount of power to maintain the memory.

I measured current consumption from the battery. It takes about 20 to 60 seconds for the CPU and everything to ramp down into their sleep state. Anything that wakes it up often kills batteries quick. I believe most of the power being used is idly switching sleep states. Can't wait for custom ROMs to allow tuning.

15 minutes of voice call eats 16% battery =/

I keep hearing some people claim how "great" their Vibrant's battery is. I am on my third Vibrant and battery life has been terrible on all of them. Just recently I noticed ~16% of my battery got drained for ~15 minute voice call. (The attached screenshot shows voice call using 27% but at that time my battery was at around 39%, which means the 15 mins took about ~16% total battery.) I just passed my 14-days buyer's remorse, so exchanging it (unless I want a "like new" one) or returning it are not an option. Any suggestions on how to improve battery life? I already keep the brightness on the screen to the lowest it gets.
Thanks!

Hmm that defintely is not normal. I would check with the store in getting another replacement. 15% drain on 15 min call is not normal for any phone.

There is a bug where if you power down the phone while it's charging, then the reported battery % is higher than actual. Perhaps the seemingly fast drain is a result of the reported value "catching up" to the actual level.

Edit: So I figured out where you're getting your numbers .
Still doesn't seem right though, did you notice the battery percentage before the call by any chance?

My rooted G1 had that same bug. Start charging it, power it down, power up and from completely dead it would show around. 24% in a couple minutes of charging. This phone I've noticed does it as well as newer blackberry's. Bizarre...
What I would suggest is draining the battery till it dies, charge it back up fully and see if you can have it happen again. Could've been a fluke.

looks like a bad battery reading to me.
Complete charge, complete discharge, and complete charge should reset it.

Yeah the percentages do need to be calibrated and sometimes they are off a bit, say 100%-90% actually often goes faster than 80%-70%.
The batteries are also partly responsible since discharge Ah is not a completely linear relationship with voltage (which is why the percentages need calibration).
I would say unless you have a rogue application on your phone eating battery it is more likely just how it is being reported.

So if battery A has x% greater mAh than battery B it does not mean A has x% greater battery life?

I'm having same issue. Battery life on my Vibrant is just horrible. I can barely go half a day until it's fully discharged and that's about 30 min talk time an hr maybe browsing apps and internet and a little WIFI/BT. Just for example I charged it after complete discharge and took it out at 11.30 pm last night, drove my brother to the airport and back around 1.30 and while it was sitting in the car and a few calls I made, it already went down to 74%, I purposely left it without charge till morning.... at 8am it was showing 47%... WTF!!
I have rooted the phone with update.zip, I have installed ATK and have Crazy settings on it.... one thing I don't get is that after it kills apps, they keep coming back every few seconds. Also brightness is at the lowest and no live wallpaper...
UltimateJuice by the way is showing 1.58 times, which is BS... right now it's 10.30AM and its down to 38%....
Any help would be appreciated!

Vibrant's battery life does suck, even with the supposedly power efficient processor and super amoled!!!!!!
Samsung has some more work to do. Hopefully, the froyo update can alleviate the problem!!!

Read this first.

Anytime the screen is on its eating battery. We have the best screen in the market. If you really want a conservative wallpaper use something almost all black or solid black. When a AMOLED screen is displaying black the LEDs are off.
For those "apps that keep showing up" those are due services that are running in the background. If you don't use the app often set the notifications to a lower time or set it to update manually.
If you've rooted there is a thread on "how to keep your phone quick and snappy" read it. Also fix your permissions through recovery. Rogue apps apps can drain battery.
after 3hrs of on & off hard using (minus extra long phone calls >45mins) I can pull 12-16 hours easily on one charge.
Look into things like eugenes vibrant 6 & JACs UV(under volted) kernel.
GL and car chargers are awesome!
Vibe the XDApp

Battery life on my Vibrant has been superb. You might need to change settings or something. This screen shot was for today with lots of calls and market shopping and I even watched a movie. I do not use a killer, yes I'm rooted with lots of tweaks to my notification bar. I'm using the spiritbomb lwp and its been great.

Unfortunately, the battery life on the Vibrant just sucks, compared to the iPhone.
I came to a Galaxy S and a Vibrant form the iPhone 3Gs.
With the same style of usage, the iPhone lasts at least 40% longer than the Galaxy/Vibrant.
I like the phone a lot, but am really unhappy to have to constantly think about how I use it, to avoid it dying on me before the end of the day.
Basically, with moderate use, it will last for a day, but if I go out after work and do a little texting or take a few pictures, it will die before I get home.
12-14 hours is really not good, since with my old iPhone I used to be able to last almost two full days without recharging.
Plus, the blocking of the camera at 15% of battery life is a truly idiotic decision by Samsung.

Thanks for your feedback! I am newbie in the Android world, as I come from the Apple planet. It just takes time to get used to it.
As for XDA App, where can I get it?

I am looking into the mod for the notification bar, specifically the battery. I have seen a circle battery with percentage, where do I get one?

XDA is your Friend
Search XDA for all ur app and theme needs, as for the Iphone being better on battery. I dont doubt its better, but from my experience and many family and friends showing me there iphones they are always tethered to a power source. Theres no better test than driving 300+ miles a day every day and coming back to the hotel and seeing my phone tell me i have been using it for 20+ hours and i still have 25% charge. I am constantly using my phone for calls, text, movies and such. Without my phone my wife would probably divorce me lol The amount of travel i do via plane, train and automobile is all the real world facts i need. Vibrant is a keeper.

Yes it sucks.
And under 15% it's not allowing me taking pictures!
Come on, I know I am under 15%, but I still want to take 1 or 2 pic!!

Unique Battery problem

Sorry to start another thread on battery issues but I was unable to find a scenario like mine.
Hey everybody, Im new to the android scene, just got my vibrant less than a month ago. Before that I had an Iphone 3g. So far I like the phone but the battery life is horrible. When I surf the internet on wifi or 3g I noticed that I use like 3-5% in a matter of 5 mins. Is this normal? I consider myself to be a light-moderate user and have been getting and average of 12 hours or so on my vibrant. Also if it makes any difference when my phone is idle or being used my temperature runs around the high 80's low 90's but when being charged it drops to the low 80's or high 70's. What is going on? How can I get more 20 hours on my phone? With the iphone I used to get an easy 15 hours and still have like 40-50% remaining.

When I first got the vibrant, it had pretty bad battery life, I would lose like 25% while sleeping 8-10 hrs. So light usage would be like a day. Slowly I started to get longer battery life (2 days on light usage). Recently I could get up to like 3.5 days on real light usage. After updating to JI6, max I can get now is like 3 days. I didn't really do much and I tripled my battery life by just giving it time.

Thanks burntrat I guess ill be patient. And I must mention that I am running stock.i was just worried because my battery temperature gets colder when charging and warmer when idle or running.

Hey burntrat or anybody, has your battery ever acted sort of schizophrenic on you? I mean one day I leave it on standby and its drains like 1% in 7-10 hours another day I leave it on standby and it drains 18% in about 4 hours. Whats going on?

My battery has been draining inconsistently lately. It drains faster in the 50-100% level. Under 50%, it feels like it drains slower while doing the same stuff.

if your phone is draining a lot during standby or sleeping. There may be a rogue app out there or an app that didnt shut down properly. (I guess that would mean a rogue app)

@aamir123 and burntrat: maybe you guys need to calibrate your battery? Also the stock rom usually has a lot of bloatware running in the background. Flashing a custom rom oughta do the trick.

How do you recalibrate the battery?
Sent from my SGH-T959 using XDA App

Try this. Download the system panel app from the market. You can set it to monitor your system and it will chart what applications are running and how much they are using the cpu. If you find you have some unnecessary bloatware running in the background download titanium backup and freeze those apps.

There are a lot of different ways mentioned in different forums. Try this:
Let your battery drain all the way to the point when it turns off by itself.
Charge it while its off until its full.
Unplug it, turn the phone on, then plug it in again.
After it reaches 100, unplug the charger and turn your phone off.
Once off, plug it in and let the charging complete.
Once complete, unplug it and turn the phone on. When everything has loaded, turn the phone off (note: no charging involved in this step.)
After it turns off, charge it one last time until 100%. After this, go into recovery and clear battery info (or cache, I forget). There you go
Oh, and its better if you don't download too many apps that monitor battery usage, cpu etc. cuz they will contribute to the battery consumption.

It isn't a good idea to let your battery drain all the way to zero since it is lithium ion. I think skipping that part and just charging it when it's on to full, then off to full, then on to full, then off to full and then wiping battery stats would suffice. Also you need to have clockwork recovery to wipe battery stats.

When the phone turns off by itself, the battery still has some juice left in it to prevent it from losing the ability to charge, if that's what you meant by not a good idea cuz its lithium ion. If thats not what you meant, then please explain why.

Agreed. In my case, I barely lasted 12 hours on moderate use with any of the JI6 2.1 ROMS (Eugene's, Bionix, Fusion, etc). I think after I updated to 2.2, all of the ROMS have been giving me 18+ hours on moderate-heavy use no matter what modem or kernel I use.

So where is the "unique" problem?

Specific battery life issues

I have had a rooted atrix since release date.
The battery life has been frustratingly bad.
Right now (9am) I am at 86% with the screen having been on 26m.
It's very very very common for my "running" time in spare parts to be 2-3x my screen on time.
Partial wake usage is led by the process: UID 1001, followed by Android System.
Network usage is dominated by process "0" followed by android system. "0" is so far in the lead it is unreal.
My total in all time stats are:
Running 28%
Screen on 14.1%
Phone on 1.5%
Wifi on 30.5% (??????????????)
Wifi running 17.3% (Even more ????????????????????)
I have frozen all of the recommended freezing apps. I have beautiful weather set to refresh every 2 hours. Facebook, twitter, etc, aren't set to notify me at all. I have no idea why it's so bad.
It's coming to the point where i'm about to give up. My nexus one gave me better battery life.
I've already tried a factory reset, is there something i'm overlooking?
What is UID 1001? What is "0"?
The most frustrating phone I've ever owned. It is so close to greatness. I wish I could get rid of this terrible terrible terrible motorola blue garbage.

I've been struggling with battery life too for some reason. If you have Tango installed, get rid of it. That app didn't let your phone sleep and drained battery. Now my problem is the sensor usage when I check my battery history in *#*#INFO#*#*. Android system has been using the sensor 100% of the time for me. I factory reset it, but that didn't work either. I'm really contemplating going back to my N1 too, which is such a shame since this Atrix has so much potential

I turn wifi on and off. On a home off at work. Gps is on. No bluetooth ever. Autosync is on I guess. It may be frozen though.
Right now my phone is at 63% and the screen has only been on 37 minutes! This is pathetic.

Has your phone ever gotten down to 5%-10% or do you always recharge it before then? I've had issues in the past where a lith-ion battery loses lots of its capacity until completely drained and then completely recharged. It seems way to early for this for you, but it might help. From my limited experience, gps is very very costly in terms of battery.

Draining a li-on battery completely more than once a month damages the battery. It's a very bad practice.

I'm having the same issue with UID 1001 under Partial Wake Usage and I also have the 0 under Network Usage. Under Partial Wakelock it shows UID 1001 and a total time of 7h 7m 30s under Total in all time. I've tried a hard reset and still showed up. Have you guys checked to see if you are getting the same thing. If people are getting good battery but have this then I'll feel a little better. I just thought it was weird. I still get this even with WiFi, BT and GPS off.
Under Network Usage the 0 is pretty much all blue all the way across and a little bit of pink at the end. If i try to click on it "Settings has stopped unexpectedly" message.

The battery doesn't seem to last as long as my n1. With my n1 I still have roughly half when I get home from work. The atrix was at 30 or so when I got home today and its been similar most of the times.

I am also not terribly happy with the battery usage. Maybe its because I have WiFi on all the time?
Also, just having bluetooth on (but not connected to any BT devices), shouldn't be a big drain on the device.
The main auto-sync feature I have is Exchange push notifications. Gmail only syncs every 3 hours.
I also have device running time on Spare Parts higher than Screen On Time.
I am going to try a factory reset and add applications one by one to see if that has any effect.

I've let it fully discharge once. I just can't sort it out. People in the other threads are getting 1+ DAYS uptime.

With light usage I was originally down to about 20% at the end of the day. That's now improved to 50-60% charge after installing the 'green power' app recommended in another thread and further improved by turning off the auto brightness.
Auto brightness is good but needs to be reduced by about 30% to be useful.
Gps Navigation with google is the biggest battery drained I've seen so far. Its on the order of using 1% charge per minute. Im hoping that an offine nav app will be more efficient.

There are a lot of reviews stating that spareparts IS the cause of battery issues. Maybe uninstall that and use the built in battery manager to determine use?

Really? It seems to just be a monitoring app.

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...

Hm I'll have to test with it on and off. I use it because I get spotty service in my house and don't want it searching for signal all the time.

Interesting. I think you are right, we are essentialy minimizing out idle drain to a certain extent. However, even activily using my phone it drans slower than stock with this rom. My next run ill try and use it all day to see what I get.

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.
