I have heard good things about juice defender, but i have a basic question. It says it turns of data during times, or when certain apps are running, etc...
Now, is the data only internet connection? Or will it interfere with my ability to get texts as well, because that would be a deal break for me.
Data is only the internet. The only things that you'll be missing out on are e-mails, which will still come through based on your schedule set up and when you have your screen on.

Heard so much about this app, tried it and took me only a few hours to remove it. When screen is off, it kills data, so basically apps like K-9 Mail that push my IMAP-idle email accounts and poll other accounts are basically impotent.
Plus the interface is confusing with a myriad of settings and no real hold on what settings stick or what not to set. I understand the concept of the app but it's not for me. With stock rom and mediahub-DRM-whatever-process killed off manually, i get by a work day with 50% left over on the train/bus-ride home, more than enough to do stuff before i get home.
I dave been using juicedefender for 3 weeks and it has maximized my batt an overall of 1.4x. The interface is confusing for those that don't spend time and learn it....its granular.

U can set it to fcetch data on certain time intervals and u can get emails like that

I'm totally happy with it - I'm getting a rating of around 1.7x to 1.9x I know I can easily go a full day on one charge. The default setting of enabling data every 15 minutes is enough for me - I don't expect to get emails that are time sensitive to the point where a maximum of 15 minute delay would be detrimental. And I play with my phone a lot so I'm usually waking it up to respond to texts and it reenables data then anyway.
edit: I'm not using any battery tweaks or DRM disabling stuff. I'm stock except for rooting.
You guys and this juice defender. you use more battery with this because it is always running in the background. i get 45 hours without juice defender or a task killer. 1 day of battery pleasssseee i could get 2 if it was left in standby or more. no drm removed. root, cwm, galaxy rom and kernel di18 & blue minimalism
Oh well f me... If you're getting 45 hours that must mean I can get 45 hours because, you know, our geographic locations have the exact same coverage and we have the exact same phone usage patterns. Wow I feel like such an idiot. Thank you. Thank you for showing me that juice defender, instead of increasing my battery life by a good 6-8 hours, is actually killing it by 21 hours...

That's fine - always be skeptical especially when an update comes out to improve performance. I'm about to test the new kernel without this to see if it's worth it. But I know that keeping data off on my Hero tripled the battery life and since having this phone it's definitely increased it. But you can't tell me that I'm losing 21 hours of battery life by using it - and definitely don't try to make me feel like an idiot for using it either.

Im sure its not killing you by 21 hours. prolly your STOCK sync settings though. i only turn it on for a minute or two 3x a day. but go with out it i bet its prolly like 8 hours. think about it when your screen is off it is running. well that is another process that is draining battery unneccessarily. My entire phone is set up like on demand it does what i want it to when i want it to not when it wants too and all of this is acheived with stock settings and checking every app for update frequency settings. I use my phone a lot so i need it to be there.

So for argument's sake, and because I wanted an actual test, I installed your setup based on you're post earlier, andromeda rom, no juice, etc. gmail and facebook sync off. I even went in 4 times throughout the day to turn off running services. I got 11 hours and that was with charging while I was in a vehicle. So I would say about 9 to 10 hours really. TWS was only at 16%. Display was the biggest battery drain at 82%.
So now that I've done this, I can say without a doubt, for me personally, juice defender is really extending my battery life. While running juice defender, I take my phone off the charger at 6am typically and when I go to bed at midnight I still have over 20%. And if I don't plug my phone in, I can wake up at 6am the next day and the phone is still on.
You have a setup that works for you, and I have a setup that works for me. In my setup, juice defender gets me through a 24 hour period without charging. Now that I've got the andromeda rom and kernel, I'm going to test battery life with juice.

45 hours is meaningless when you just let the phone sit in standby the entire time. That's like the car commercials that list higher mpg than they get in the real world.

I have juice defender installed only for it's two toggle widgets. With defender disabled it doesn't run in background, I take advantage of the data toggle widget and I've seen it save as high as 5x's life.
I just switched from the G2, and I don't seem to be getting as good of a battery life. I just went down from 50 percent to 4 percent in 3 hours. Is this normal?
I don't think my phone is sleeping when the screen off. I'm kind of new to android, so excuse me asking, but how do you check if you phone is not sleeping and draining battery while idle? Is there an application or something to check?
One more thing, I just got the new update yesterday. I heard that it's not good to use a task killer, but I'm now using the built in task manager to close apps before I lock my phone seems to be helping with battery life. What are you opinions on this?
Check the battery thread, life seems to vary along among the Vibrants. A lot are reporting 11-15 hours of use before needing a charge.
I read that it's good to put Wifi on never sleep (if you're on Wifi) and use a black wallpaper
Interesting, how do I go about changing the wifi to never sleep? I can't find it in the settings!
Drm running. Go2 apps running- Apps & stop it

If you change WiFi to never sleep, it eats battery like crazy (at least for me, I'm bought with no data, and could barely last a day from when I woke up to going to sleep). With WiFi art to never sleep when charging, I only drain around 40% in an awake day (from when wake up to going to sleep).
Also, when I set WiFi to never sleep, my cell standby usage skyrockets.

Extend battery life
Couple of things I have noticed with this phone
1. Get an app Task manager or similar type apps. There are a bunch of them in the store and here. This will allow you at one click to see what is on in programs and better manage that.
2. Go to the Development section here and read the Bionix 1.9 Thread. It explains how to recondition the battery. Even if your battery is new it is good information understanding how the phone views the battery.
3. If I am out of range or do not need, I stop the wifi and bluetooth. In the menu you can set the settings alot of ways, so you just have to experiment on this. (In home screen, hit lower left button and go to settings)
4. I use my email and phone ALL day (min 10hrs) and typically, I get 15-17 hr of use before it hits 10%
5. Finally, once you are comfortable with the phone, you can load a custom ROM from the Development section. The developers here are very through and Do squeeze the most out of the phone.
Good luck and you will love the phone as I do.

1 - terrible advice - esp with JI6 having one built in (long press home).
2 - This is also in the General sticky
5 - try bionix 1.9.0 (or 1 if you want alt lock screens) and try JACs oc/uv - great battery life so far.
On average use I get close to 24 hours out of a charge using mostly WiFi and enabling no-sleep option, running Bionix 1.9.1 with stock kernel with JI6 modem. I'm also running LauncherPro Plus with facebook widget set to auto-refresh every 5 minutes, the most frequent setting for Google sync, and NoLED notification. I think that is very reasonable.
p.s. I do not use task manager since the operating system is supposed to manage the apps on its own.

I use an app from the market called Y5 (free) to automatically shut down wifi if I'm in an area without it and back on if I'm in an area with it.
Works well for me.
My vibrant is less 23% after being off the charger for 4 hrs. One of those hours was me driving without using it.
Something is wrong. Dunno if it's the update, but something is lilling it FAST - wifi ang gps off the entire time...

I use the living hell out of my Vibrant, and usually it lasts for about 4-5 hours. This being during playing games with brightness maxed, or streaming music over 3G and/or Wi-fi.
If I have a day where I am not doing the above, and just using my phone for emial and the facebook and gmail synching, I easily get over 10 hours before I hit 20%.
All in all I am quite happy with it's battery life. I have just learned to leave my phone on the charger till full charge after streaming music drains it to <20%.
I really should put MP3's on it and test how much that drains the battery compared to streaming.
Either way, I get better performance on battery and memory management then my old (work supplied) BB Bold.
My G2 definitely has more battery life than my Vibrant. That said, once you apply the above mentioned tweaks and especially with JAC's OC/UV kernel, and setcpu set at 200-1000 at conservative, the Vibrant battery life improves quite a bit. Still, its not as good as my G2. But not that bad either..
Keep in mind that the G2 doesn't have to power a billboard sized SAMOLED screen either.
Other than that flash on of Sombionix's ROMs with either of the new kernels and then recondition.
I get pretty good battery life because I don't have 3G in my area so I keep it forced to edge and I don't use bluetooth ever and wifi stays off unless i need it.

Ditto!
Fully charged on the way to work. On the charger less than 4 hours later with moderate use. No better after update. Was using a task killer with minimal improvement. Love the Vibrant but despise it's battery life.
Something is wrong. I just went 26 hours down to 19% before charging

People, recondition the battery. It's easy.
Charge it to 100%, keep it plugged in and reboot to recovery, clear the battery stats, drain it all the way, then charge it back to 100% again.
You can start in the morning before work/school and finish at the end of the day. I've never had an issue with battery life on this phone. I can play 6 continuous hours of video/games on this thing and still have battery left.

Can't get past "Reinstall Packages"
I am trying to recalibrate my battery after the OTA destroyed it, but every time I select to reinstall packages so I can get to the battery section, it looks for Update.zip on my sdcard, and it wont let me get any further. All I can do is reboot the phone.... any suggestions?
Does the gps really use much more battery if kept on? I've always been under the impression that it would drain the battery quicker than anything else. Recently though, I've just been leaving it on constantly and have noticed very little extra battery usage. It seems to come on briefly when I do a search or other location using services, but it didn't seem to be an extra drain otherwise.
Anyone have any input or some input about gps battery usage?
Sent from my <tw> powered vibrant.
As far as I know, the GPS only kicks on when an app requires it. So unless you have something in the background that's constantly asking for your location it shouldn't really drain the battery in a way that would be notisible.... As far as I know

Sounds about right just make sure you don't have a lot of apps running that use the gps
Sent from my EVO 4G using XDA App
In earlier versions of Android, having the GPS setting "on" actually activated the GPS system directly. In current versions, the setting only controls whether GPS-aware apps are allowed to use GPS at all, or not.
So as you have surmised, leaving the setting "on" doesn't use any additional battery power unless you're actually running a GPS-related app (Maps, navigation, camera, etc).
To save battery, just turn on GPS whenever you need it.
No idea why should leave it on all the time, coz it is really draining battery if it is running (to be clear when it is really running but not just on)
I haven't turned my gps off in 2 months and I average between 12 and 18 hours of moderate use.

The point the OP is trying to make is that GPS doesn't drain the battery unless you're in an app that uses it.
I leave it on because only a handful of apps use it, and I'm usually not in those alps for hours at a time.

For people who are prone to losing their phones, such as my GF, its a good idea to leave it on and installing an app like Lost Phone where you can send the lost phone a txt and receive a map view of its exact location. As far as i know the android OS does not support remote activation so it must be left on. Like others have mentioned it does not cause a noticeable battery drain while its not in use. Its come in handy numerous times...too many times...

Thanks everyone, that's good to know! I understand I will see some additional battery usage when I'm in an app that uses gps, but I was really just curious if I could leave gps "on" while idle and not experience any additional battery use.

I'm going to make things a little different now. I see a lot of threads here, and the only solution are: don't use X, low down performance, blah blah blah.
I'm going to make a change at your psychological side, or at least try. That's your worse enemy, which will make your battery last shorter.
**First part: testing ROM+Kernel combo
1. Install your ROM, delete the apks you don't need, and make some tweaks you want. Done?
2. Install another kernel.
3. Configure your device by installing your apps and stuff
4. Reboot
5. Test your combo for 1 day!! Only 1-one day.
6. Read second part to see if your battery life is good
**Second part: what should you consider while testing your combo
1. After the one day test [morning to evening], is your battery still working? If yes, you HAVE A GOOD BATTERY LIFE. You shouldn't care about how % the battery is, as long it lasts for the day.
2. If your battery is really going down fast, and it doesn't last till evening
a) Change kernel and try for another day.
b) Use BetterBatteryStats to see if there's something pissing off your battery
c) If you really need this extra juice to make it last till evening, low down ONLY A LITTLE BIT THE PERFORMANCE
3. Is performance good? If yes and your battery lasts or the day, you may now be happy.
4. Is performance bad? If yes, I'm going to say something to you. WHY THE HELL SHOULD ANYONE BUY A FREAKING 1,4GHZ QUAD-CORE **** TO HAVE BAD PERFORMANCE? Increase your performance, and if it's enough to get it alive after you go home, it's enough.
**Third part: things you shouldn't do
1. Don't put the % at status bar. It only makes you paranoic about looking at the battery %
2. NEVER check for available RAM, or battery %, but if the battery icon is going down quickly, make the basic stuff to save juice. Checking RAM and stuff will only make you complain at your ROM/kernel forum, even if it's normal. And don't use task killers, Samsung's task manager, etc. Cleaning memoy will only piss off your battery and cpu.
3. ALWAYS put your phone in the charger before you go sleep. Why would anyone want to make the battery last for 1d or 2d? Bull****, just charge every night, I see no problem by doing that.
4. USE, ABUSE, RAPE THE CRAP OF YOUR PHONE. Your phone is there, and have you think about how you use it? To check for battery % or actually use the phone?
**Observations
1. There's no such thing as miracles for that. Anything can count to change the battery drain: temperature, external temperature, pressure, apps, how you use it, etc...
2. Choose a stable kernel and DON'T undervolt it. Yeah, undervolt can be useful, but makes stability looking like crap.
3. This may be completed later.
Hope I could help some battery freaks here

I know a couple things to help with the battery drainage, from personal experience.
1. GPS, turn it the hell off unless you truly absolutely need it.
2. The Facebook app. One of the biggest battery hogs I know of besides heavy 3D-games.
3. Sync. Why choose to auto-sync? Turn it off and sync only when you feel you have to. Check Gmail manually, manually sync contacts and stuff when you feel it is needed
4. Location services. Might prove useful to some, while to others it drains the battery quicker.
These are the four battery hogs by my experience. You may not think the same.

GPS is really only on if an app is using it, if you have it on but an app is not using it it will not drain the battery. It's shown under settings battery and it shows GPS using no battery unless an app is using it.

That does not include layovers. But at that point you have access to outlets.
Now with that out of the way. Lock this shiz.

Hello there guys. I was thinking the other day about how the phone has a power saver mode. I also have the Battery Guru installed. I'm also giving Lux LIte Dash to see if I like it. Couldn't all of these be conflicting with each other thus limiting my ability to save power? I love the battery life on my device. I'm just wondering if I get rid of one of these, I could be saving even more.

Just my opinion. I have never found a battery saver app that actually worked as intended. Most use more battery. Greenify is the closest thing that keeps apps from running and doesnt use much juice. As far as having multiple i think its a little over the top. Just use one you think works or none at all you will be beyter off. Coming from someone that came from a gnex with horrible battery. Nothing worked except a bigger battery. Lol. Good luck
