Most Valuable App (Ultimate) Samsung Galaxy S3 went from 6hrs battery life to lasting all day. Increased battery life 2.32x! Turned off phone's auto brightness, set display to zero, then set JD so it adjusts brightness. Samsung Galaxy Note 3: Still working well. Keeps aggressive apps from killing my battery. UI helps me know what each setting does and if I need to use them.
Amazing, worth upgrading to Ultimate Juice Defender simply works. Upgrading to Ultimate was an awesome choice for me because it gave me way more control and way better battery life. I had a 1.35x battery life with Balanced and I know get 2.38x with my custom settings. I was skeptical at first, but I am now convinced. Pros: - Increased battery life - Easy to Use Cons: - Have to wait for data connection when turning on phone (takes about 5 seconds for me) - Updates from Facebook, Twitter, Email, etc do not come in right away
Best by a long shot If you're looking for an app that is going to manage your apps, than this is not the app for you. Most battery consumption comes from your display, Bluetooth and data or WiFi connection. Juice defender is that kind of utility. With ultimate you can configure apps. You can set data or Wi-Fi to connect for certain apps, and you can set data and Wi-Fi to disconnect for other data hungry apps. Of all other battery utilities, this one doesn't touch your apps, and still saves more juice than the rest!!
Does really well but.. It does save my battery and does it very well. The downside is that it severely limits the overall experience of the phone. Mms don't send without turning it off and I have all data enabled but it still wont send. Goes right through when the App is killed though. The applications that require data don't work as fast with juice defender enabled. I like the App but I wish I didn't have to sacrifice the performance of my phone, galaxy s2.
Great little app! The basic mode in the few version has a trick for saving battery. It switches off 3G while the phone is not being used and turns it on every time you unlock the phone. And this does wonders to the battery life. The pro version has some additional features like location based auromatic Wi-Fi access. So basically, a must have app if you are not in the habit of using 3G data continuously, and are okay with periodic data sync.
One of the best apps ever to hit the app store! This has been my favorite battery saving app for years now, ever since gingerbread was the latest version of the Android OS. I've tried other top rated apps but I always end up coming back to this one because of its low profile/footprint and superior performance. Perhaps it's because it was originally designed at a time when Android ate cell phone batteries for breakfast. Either way you can't go wrong with it no matter what kind of cell phone you're using. Even older/cheaper phones can benefit from it.
