How is Juice Defender.. Do you recommend it?

Do anyone here use the Juice Defender app from the market?
If so how is it... has you battery life gotten better or worst with it?
Sent from my PC36100 using Tapatalk

I use it. For the free version it did not make a big difference for me. The ultimate juice add on has improved my battery life a bit. you can pretty much get the exact same effect if you turn off mobile/wifi manually but if you are like me and forget to do that 90% of the time it can be useful.

I tried it a while back and to be honest I didn't notice a difference at all. Didn't help nor hurt my battery life.

I like it... I think it works.

I use it all the time, it has made all the difference for me. I manually tweaked the settings to fit my needs, and my battery now lasts 16-20 hours instead of the 5-8 hours on froyo CM6.

Really? Do you have Ultimate Juice too? And would you mind posting what tweaks you made. I am curious

I think it depends on your usage. I am getting very good battery life with just Stock atm (16-20 hours fairly easily).
If you are in situations where you have low/no signal. I could see it saving you a fair amount of battery life.
For example if you worked in a area with poor signal all day and often forget to turn things off or turn wifi on.

Tips to GREAT Battery Life!

Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you

I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.

Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..

I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...

Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.

I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.

Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours

neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.

Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.

Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

How long does 1 of those batteries last?
Sent from my HTC Glacier using XDA App

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.

you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.

My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.

Gingerbread so far...

So from a GR-12 standpoint I must say gingerbread handles just about everything better. with the random odd bugs here and there... so far gingerbread is already showing some awesome stability and speed. much kudos out to the devs here! You guys do a great job and from what I've seen here so far... you put up with maybe one too many ignorant rude individuals. BUT! I would like to extend my thanks to all you devs and helpful members here... and for making my switch to android not only an informative one but a great experience all together.
So... anyway. loving gingerbread (GR-12 mainly). After loading up launcher pro almost every single bug or issue has vanished. seems the twlauncher has some deep seated issues lol.
Looking forward to the new releases!

I totally agree, Ive been running GR-12 for a couple of weeks now and its silky smooth. Oh and im also using launcher pro for the same reasons. lol

A different launchere makes all the difference doesn't it!? After I realized that every time I had a snag or crash it was "twlauncher"... I figured I'd try replacing it. and sure nuff... Awesomeness came spilling forth. Honestly haven't had a issue since. (well I flashed the kc1 modem which gives me the gps performance I need... ).
Outside of my own retarded moment bricking my phone while flashing it... Tearing through 3 old power supplies to get the right combo of resistors to build my own jig.... lol! But all is well that ends well.
What's everyone else's setup / experience with ginger on their cappy's?

Does GPS work on your Gingerbread ROMs? I know the Vibrant it doesn't and I am on ATT, so I am looking to trade for a captivate if it does.

significantly better than froyo (at least for me). There are some people with a battery drain issue but I'm thinking its an app thats not optimized for GB. I dont think its a ROM or KERNEL issue - but I'm not a dev so I can't back my statements up.

Both battery and gps are better on GB. Gps is wayyy better...

Are you able to give me like how many hours on average you are getting? I appreciate all the solid feedback.

Gingerbread has been horribly buggy. The battery life is just plain awful, it's laggier than 2.1, and it killed my dog.
Someone was bound to say something negative, so I just got that out of the way. Lol
Actually, GR-12 makes my Captivate run as smooth as my Inspire. I got about 12 hours heavy usage with the screen almost max.

that's a loaded question because it depends on MANY factors:
-signal strength in your area
-3g vs wifi connection
-general phone use (phone calls, sms, games, etc...)
For me, the phone lasts MUCH longer. I can go about 20-24 hours until I need to charge again. Thats with medium use and wifi connection 80% of the day. On standby, my phone usually drains 1% - 2% an hour.

Thank you for all the help. The response here is much more positive than the vibrant forums.

glad to help out. hope it works out for you.
EDIT: I should add, though, that when I'm not on wifi (using 3G), my battery doesnt last as long. So I prefer to be on wifi as much as I can.

That is good to know. I will keep that in mind.

So far on continuum its been rather smooth, using go launcher btw.
Battery life is bad though. Less than 8hrs with moderate to heavy usage. I need to fully recharge two to three times a day now.
On froyo I'd get 12-15 hours with similar usage.
Gps works fine, but then mine did on froyo before.

I'm experiencing battery drain, GR, Continuum and Mosaic, I leave wifi on and after 9 hours (fully charged, battery stats reset, standby mode [literally 0 use, I was asleep]), cell standby had used 33%, wifi 30%, .... I had 52% battery left.
GB is smoother, for sure, once kernel development ramps up for GB (JVB, JVH and JVO, ... JV#) i'd expect to see more tweaks include power and performance.
If you need battery life and don't want to risk flashing GB, wait.

battery life *IS* going to depends heavily on how much you use your phone. It's hard to compare battery life amongst people that cannot stand next to each other and compare phones because describing "heavy" use is different for everyone. My version of heavy is not the same as the next person.
the only real determinant of battery life that we can all use as a comparison is to see how much battery drain you have on standby or to run some sort of application that runs videos (ie. benchmark apps) because we can all do that. If your phone drains 2x as fast as mine on standby, then we have a problem with a rogue app or something else.
(clarification: I dont mean to use a benchmark app to see the results of the app itself. I just mean to run something on the phone to drain the battery quicker and view the battery life at the end of the test).

I've always experienced better battery life with Froyo, and I use my phone every single day for reading PDF's, listening to music, texting, calling and surfing the web. Maybe Gingerbread has better standby battery life, but when getting a "full" use out of my phone I've always lasted longer on Froyo builds.

Getting best battery per charge out of your skyrocket.

I am opening this thread to facilitate skyrocket users to share their experiences on getting most out of one charge.
I generally prefer something that shows percentage on top since the battery display does not provide detailed info.
I have tried few free aaps and finally found the best one. It is '2x battery' app. I used to loose 4 - 7% per hour in standby mode. With this app, It gives me 1-2% most in burn in hour. While writing this, I am 36% after 17 hours of regular use.

im at 11 hours and have 89% left using Juice Defender plus..

The only problem with JuiceDefender is that if you use messaging apps like Kik or WhatsApp, it will make it so that you don't receive the messages unless you have your phone active, making your phone pretty much useless.

I dont buy anything til I see proof of screen time and battery use screens.
Just got the phone yesterday, but I must say, coming from the epic 4g touch where I was getting 25 hours with 5 hours screen on time, it doesn't look promising.
But to be fair I haven't underclocked, undervolted and all the other tricks yet. Properly working sleep mode is essential.

I will try the 2x battery,

I use JuiceDefenderPro; custom profile
After 7 hours on battery, I am at 90%.
light calls, 1-bar of signal on 4gLTE, apps grab data every 15 minutes.

Anyone see results w/ underclocking?
I am using Antutu's CPU Master (Free), but my results have been inconclusive (sometimes uses less, sometimes uses more.. can't tell). I am considering getting the paid version of the app (or SetCPU or Android Overclock) to try the screen off profiles.

I use set CPU to underclock when the screen is off and when battery is low. In my experiences the savings are noticeable but not major.
With set CPU, juice defender, and a de-bloated rom I usually go to bed with around 30% battery remaining. That's about on par with my nexus one running cm7.

I haven't really had issues with the battery on my skyrocket. Then again, I'm not I'm an LTE area but you can pretty much expect bad battery life in an LTE area. Regardless, I have noticed something odd about the battery on my skyrocket, and maybe someone can confirm my observations here...my skyrocket tends to lose battery fairly constantly at first up to about the 80% mark then slows down the rate off loss of charge and I notice another huge slow down in drainage at the 30% mark. I've seen this repeatedly no matter what I do. In other words, screen on or off, I tend to see this happen. I'm not complaining as I think a 20 hour battery is great when using it heavily. And I kind of think of the slow drainage at the 30% as a nice perk. I'm running it stock so I can't chock it up to anythnng other than the phone. Any thoughts?

Why does everyone say this about LTE? It is simply not true. All LTE does is give you higher bandwidth with less delay. Wan't good battery life, run a custom ROM. I am running the ICS v4.1 and I must say it is much better than anything else I have tried. I keep 4sq, FB, twitter and gmail all running in the background along with BeWeather updating every hour.

Everyone says that about LTE because (from what I've read) running LTE requires more power due to several reasons. I did a quick search and sprint may be a great indication of proof of the power consumption of "4g" from what I've read their phones disengage wimax when not in use in order to conserve energy. If LTE is faster and operates at higher frequencies (if I'm not mistaken) then it should require more energy. I could go outside the box and come up with some equations that relate frequency to energy (they exist) but I will admit I don't know if they can be applied to the circuitry in phones though I don't see why it wouldn't as the theory is sound. In any case, yes running a custom rom will do wonders for battery but some of us haven't taken that plunge yet. As it is, my stock skyrocket is doing great for me lasting 20 hours. Im out of the house at 6am and usually don't get home till 8 at night. It makes it through that with ease. I'm happy with that. Bring on the LTE, I'll cross that battery consumption bridge when we get there.

What is best ROM for battery life?

Hello,
Anybody who flashed tons of different ROMs, can you comment which ROM provided best battery life for you. I'm not looking for absolute numbers but comparison of different ROMs as far as battery drain is corncerned for the same user.

Is less about the rom and more about the kernel and u/v u/c in my opinion...radio can have an effect too
Currently I am on coca-cola with dag's .3 kernel using the Gideon battery saver script.
I like using that on the quickwiz rom too

Ive been flashing a lot of roms the past week. I'm currently using [ROM][UXKJ2]Buoyancy v1.3.0||Rogers/AT&T||[1/25/12]
Deff the best so far. Very quick and it's been 11.5 hours and I'm at 57%! Kudos to jomeister15 and his team!

You are on ATT network and in LTE enabled zone?

Nexus had the best for me. I also hear Buoyancy is great as well. Sky ice cream sandwhich is what im running now but i charge my phone a lot. An update should be coming soon for battery life fixes on it though.

radio on or off?
I've been running TPC v3 on my 727R for about 2 weeks, with his oc startup script. My battery life wasn't so great until I decided to start turning off data while not using it. Made my battery life go through the roof.
From full charged, I was still at 69% 20 hours later. Mind you, I wasn't using it that much but even still.
Which leads me to wonder: are people actually turning radio off when not in use? Because with it on, I can't get anywhere near those numbers.

What will you be missing if background sync is off while screen is out? everything relying on push notifications will stop working or will be there some other noticeable changes?

I use skyICS and I get pretty good battery.
The pic is of my first battery cycle on skyICS, with pretty decent usage on it. The red little bit at the end is me trying to kill the battery. I had wifi on, data, sync, flashlight, and ran quadrant standard non-stop for about a 30 minutes.
I think a lot of it will depend on how you use the phone. As mentioned above, simply turning off data saves you a lot of power. Going into airplane mode saves even more. I lose almost nothing in airplane mode (I put it on at night). You can get an app in the market that will auto turn off settings for you if you're too lazy to do it yourself.
