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.

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.
My battery is just getting better and better. I went to less than 3/4 of a day to more than 2 days. My battery is now at 78% and I charge my phone 20hrs ago. Thats amazing.

I always see that people suggest to turn off Data, change from 3G to 2G and stuffs like that.
I don't understand their point of view of having this phone when you have turned off everything... must themselves get a normal dumb phone.
wow some of these batt stats are crazy. my phone alone on standby dies 3% an hour...how do you guys last days?
mine too T_T
use super task killer2011.it helps u to release much more RAM and save buttery in better way.
- The smallest task killer in the world. Only 54KB.
- Kill tasks quickly.Showing the RAM occupied by the task.
- Advanced filter feature. Showing the security level of different apps or programs running in the background.
- BugFix for Android 2.0 Devices;
- Faster when you start it;
- Sort by A-Z;
5 days and counting...
I used to use task killers but find that my phone is better without them.
Last week I was on holiday and my phone lasted 5 DAYS and still had around 20% left! (no wifi/BT, minimal use, few calls, not switched off at night).
It will probably get around 2 days with normal use.
This thing is a beast. I have 30% battery left and I have been using it for 41 hours without charging it. And I use it pretty heavy on sundays and on 3g all day saturday. I think it's got the best battery life of any device i've ever used. How are other peoples battery life?
Can you post your battery usage please? Just interested what you've been using in those 41 hours. Seems incredible!

This is about the exact same results I get. I had about 30% left yesterday after two days and 4-5 hrs of usage.
I pushed about 36 hours before the device shut itself off. Medium to Heavy use (lots of browsing, some games, all around tinkering and playing in numerous apps), and a decent amount of that was standby.
Over-all, I'm very impressed with it and it has completely replaced my laptop (sold it before I got the Xoom, actually). I was actually having a hardtime leaving it off the charger because of how used to I am having to plug my devices in after a few hours of heavy use.
I did a real world test for my xoom this weekend. I used it as i "normally" would. when I wanted to do things, I just did - browse, played games, etc. I used it saturday night to show pictures of a new house to lots of people. Basically, how I would use it if I wasn't specifically testing battery life. Long story short, i went all weekend without charging. Charged fully at 4pm Friday. plugged in Sunday at 11pm with 20% or so still left.
with all due respect that's not accurate. A more accurate usage of batt life is 'display usage'
I get about 7 hours batt life. I was at least expecting 9 hours

9 is a little too much i'd say. It really depends on what app you use and how much power the cpu takes out of the battery. For example, simple web browsing and apps aint gonna run on 2 cores. Gaming on the other will though. And real life usage is really what matters.

You should consider rooting it and running GreyBlur. I was running through the battery like crazy, actually got AT&T to swap for another Atrix and still had the same problems. GreyBlur really improved my battery life and I'm able to get through a day of medium usage and still have about ~40% when I plug it in at night.
So if im going through the battery fast that means it could be a problem with the battery?

I have a celltronix universal portable power pack. (4000mAh)
Has two USB ports to charge stuff, comes with multi tips to charge stuff, but I just use the usb cord that came with my atrix. Outputs 5v, charges in about 4 hours.
I don't use it much on my atrix, but I have before, just plug it into the usb port and recharges my phone, can get almost 2 full recharges out of it for the atrix.
I like it cause I can also use it to charge other items also! Used it for my iphone 3gs before I got the atrix.
You can charge power pack from wall, car, or comp usb.(mini-usb plugin to charge it.
Just google "celltronix universal portable power pack" it will pop up on a number of sites. ( I bought mine in a truck stop)
You burn through it because you have a defective product.
Sent from my MB860 using XDA App
Yea, burning through it in 6 hours means you definitely have a bad battery. GreyBlur destroyed my battery life though, not exactly sure why it increased some peoples' but decreased others.
I had greyblur loaded once then went into recovery wiped everything then installed again first time battery barely made it to 4-5 pm when I went to for at 8 now 13+ hrs unplugged at 9am made it till 12:30am id say that's awesome. U probably got bad battery get couple new ones from what I hear they r cheap. Every phone is different t as far as battery and speed like my battery is awesome but when I run the graphic test I get 2300-2500 scores when I see others getting 2600-2800+

Ok. So i'll go to the AT&T Store and what should I say so that theyll give me a new one? They are hardass's and I need to convince them, any help on that part?
Don't lie. Tell them you think the battery life has been unsatisfactory. And with a battery that big you should be able to get better than 6 hours.
I burn through my battery pretty quick too though. Today it was dead around 6 hours (11-5) charged and now near death again. But I don't have a screen timeout, notifications on, downloading podcasts on listen(listening to them on speaker), everything on 3G. I don't care what phone you have, that's killing the battery. Its hard to make a battery last on a lazy Sunday.

Hi all.
Just a quick question. My battery life is great but i feel like it could be much better. Here are my current stats as i write this.
With this its saying i will get under 4 hours screen on time, i wouldnt say i was a heavy user. I use my phone quite a bit but i wouldnt say it was alot.My biggest problem is with the android system anyone else have it as such a big drain? Somedays its sat up at 40%
Anyone know what i can do to rectify this? Im currently not rooted..
Thanks in advance
Liam
There are just two possibilities.
LG stock rom is so bloated that it sucks most of battery or GRAM feature is so good that screen time is not really problem anymore.
Forgot to mention, my screen time was 2hr 30 so probably looking at not even getting 4 hours screen on time.. Gonna have to guess that it's the stock rom sucking up loads of battery? Would that cause the android system percentage to be so high?
I'm having the same issue here.. Getting 4 hours screen ttime though...

I can easily reach 6 hours screen on time. And I'm a heavy user and by no means try to save battery. multiple social networks, emails syncing etc often streaming music and watch videos and brightness set to a constant 75%. This is on StockModRom. So yeah I'd say something is draining your battery unnecessarily there.

Strangely, for me, when I go over ~2h screen time the Android System drain is taken over by the Screen drain. This being said, I never got over 3h30m of screen time - this is with about 10h WiFi (including overnight => ~2% drain) and about 7h 3G. I have noticed plenty of crap among the kernel wakelocks, but I lack the knowledge to remove them in the source code and rebuild the kernel.
Also, BBS is among the apps that trigger a Qualcomm bug regarding sensor kernel wakelocks (sns_async_ev_wakelock), which, obviously, lead to more battery drain.
All of this is not really acceptable coming from a company like Qualcomm (the sensor bug, in particular, is present ever since the S3 QC version...).
I'll second that Greenify is pretty good at saving battery.
I too have had a screen on time of 6 hours 11 mins over a duration of being off charge for over 14 hours
I'm using StockMOD kernel but the ROM itself is stock as i can't seem to get StockMOD rom to boot.
Also if you Root try TricksterMOD and use multicore savings etc maybe get a bit more life from your battery
Hope battery life gets better for you as it is an awesome phone would be nice for you to enjoy it as much as the rest of us

Wow just wow. This was my last charge, absolutley incredible.
This includes 1hr 45min of music streaming.
Streaming a 2hr 20 min film.
