JuiceDefender beta

I forgot to re-start Juice Defender after an upgrade - I was shocked when my HTC Incredible drained to 30% after a day of use without this app running. With Juice Defender I can easily get 2+ days of use between charges.

Needs update...no longer works right on 2.3.3 Reboots every morning when app. is open...I have sent in 3 logs..?? Aosp helper outdated. PLZ FIX !!!!!

Please add support for manufacturer's ROM eg. Miui. I enabled JD then c the log and everything were ERROR. full rated if its work ;)

Helps my phone struggle against the sapping of its power. Especially in the Agressive mode you will really be surprised how long your battery will still hold out when youre fearing the end. Fear no more. JuiceDefender is here.

After emails, still no fix to the problem.. Mobile data does not come on by itself. Have to turn off screen and turn back on to enable 3g.. Please fix! I paid for ultimate!! Droid incredible 2

Works fine on my rooted optimus V running Slimrom Jellybean. Yes, it turns off data when your screen is off in aggressive mode. If you don't like it, change the settings.

Does not work on nexus 5. It's a great app if you have an old phone but no good if you have a new Android version. Customer support is no longer available JD no longer supported

I have been using this app for years, its enormously effective in lengthening the battery - first thing I downloaded with each new phone. Unfortunately, just gotten a dual sim phone and it is totally useless. It turns off my mobile data when on WiFi but when it turns it back on, it turns on the wrong sim. This app just COST me £22! :-(

3.9.4 Quickbox not allowing JD to open once ULTIMATE is installed. Still a fantastic app non the less. 5 star once Quickbox fixed ~LG Optimus V~

Stop whining. I'm a sixty year old semi-conductor/software research and development engineer. It's fun to discover! And no I'm not a nerd. I'm a geek. I love my gangsta rap between my cello and opera's let the power's open your minds eye. Slamming someone's app helps no one at all gotta go geek peace out. Designers, doing it right dudes.

I love this app and when I recently got a new phone I immediately installed it. My only issue is that I no longer have the option to 'hide' the status bar icon. I'd like to keep the notification on, but with the icon hidden.

I am running the beta on agat63's tFD26_v0.1.0 Rooted Odexed rom that is based on 4.0.3 with no issues what so ever. It seems to be working as it should just like on Gingerbread. The AOSP install went smooth and battery life is great all around!

I love juice defender! It does what it says and nothing else. Other apps have so many extra features that I feel get in the way of the main purpose.

Updated my phone to 4.0.4 now the brightness stays at 100% after a couple of phone screen locks. I still love it anyway root your phone for more control on cpu and 3g.

Like it. Use lots of apps because I'm a individual contractor and would prefer not to carry bulky item due to chrome pain. This app helps slow down battery drain.

have Ultimate installed over the beta version on a rooted GNex with CM10. Getting 4-5 days of medium-heavy use out of a ~2800 mAh extended battery. JD works great, love all the tweaks including per-app data/WiFi/Bluetooth/GPS controls. And scheduling so my phone switches to airplane mode when I'm sleeping. Also the reduced screen brightness function. (Doggone AMOLED displays suck a lot of power.) One thing I'd like to see is per-app CPU controls. Don't need 1350 MHz unless gaming hehe.

Used to get about 2-3 days with moderate use, but subsequent updates kind of stopped working. Barely got 1-1/2 day with light use :-(, even my tablet have same issue. Earlier used to give 4-5 days now hardly a day or two :-(, trying out other alternatives in the meantime.

Being a beta one would've expected frequent updates. As this beta has not been updated for almost eighteen months one must assume development of juice defender has stalled. A pity. Such a beta should be withdrawn from the market.

My task killer did not help much. I loss battery while I'm sleeping! Juice def saves so much batt when phone is idle. Now my batt last twice as long, thanks to my hunny n juice def app creators

The most recent update seems to have fixed my issue with the configure apps list crashing JuiceDefender. I still need to keep wifi constantly training to work with location, that fix will get my fifth star. Otherwise the app is great stuff!

THIS IS A BETA PEOPLE! SUBMIT YOUR BUG REPORTS, DONT TRASH AN APP/DEVELOPER SIMPLY BECAUSE YOU DONT HAVE A CLUE! Works wonders. It has saved me from smashing this POS HTC Desire against the wall!

I've been using juice defender for a couple of years now and it just keeps getting better. Really extends your batteries. I use it on several phones, including Atrix, tthree Samsung phones, and an HTC. I am a heavy user and, except when he screen is on I get about double battery life. Juice defender really is a winner.

Good application. Saves a lot of my HTC Wildfire mobile battery life.

I'm not real sure about this app, it seems to do a good job, but when you install it, it creates two icons exactly the same and that is really a waste of space, nice app stupid representation.

it used to work real good in one of my LG phones but I am using a galaxy core prime and it continues to crash at start up and it allows to much data conectivety when screen is locked uninstalling

I've been using juice defender for years. Eventually purchased Plus, then Ultimate. Loved the extra settings. While doing a search to see if any new products are out, I found the Beta version. I actually save even more battery now. Wasn't sure what to expect, so keep up the great work!

Tried a bunch of other free ones and still came back to JD. Beta version seems to work better than regular one on my phone. Out of all battery saver apps JD's widget looks the best. Doubled my battery life. Probably buy the upgrade soon. Thanks dev.

Samsung Galaxy S2 with Jelly Bean 4.1.2 no mods and no root access enabled. Runs well using with JD Ultimate. No lag or memory issues extended battery by 30 - 50%.

This is a great app! Definitely does what it says. batt life extended x1.68 right now, x1.70 peak with free beta on Samsung galaxy s with gingerbread 2.3.5. Could easily get at least x2.00 with one of the paid builds I bet. Wish the free version was just a little more customizable though, that would get five stars for sure!

Overall the best APP for battery life. Going through the settings man can achieve easily 2x longer battery life. I'm running the beta and works fine for me w/o any bugs. Got the latest software on my android. Phone not rooted.

My phone battery went from a 4 hr life to 10 hrs (galaxy s captivate, galaxy s II skyrocket).

Great on gingerbread 2.3 but not so good on ICS and JB. Shame, I have reinstalled on my Nexus 4 to see if there is any updates but NO. O well uninstall in a moment.

The freebie works the way it states..... I will be upgrading to ultimate very sooon to get full capabilities out of juice defender

5 star for this great and beautiful app... nice :) Keep up the GoodWork! :)

It has stopped me from draining my phone when recharging is not an option. I would purchase the advanced version I could determine that it would improve my situation.

Five star performance. Normally my Note battery carried on only till 9pm or so. With JuiceDefender, it last till mid night, several hours more.

This app is set it and forget it! It does its job. I'm charging my device once a day with regular use, I used to have to charge it at least a couple of times. Content with it !

This doesnt work at all. The only thig it does is take up space and turn off my internet comnection when it shouldnt. This sucks. Fix it so it actually saves battery life and i will reinstall amd rate different
