WORKS Downloaded it about a week ago. Before I would never be able to go out for the day without having to top up the charge. Now I can confidently give my phone one charge at night and let that be it! Love it. Best battery saving app. Essential for any smartphone, even if you can get a full day out of your battery already. Thinking about upgrading to Plus for even more power.
Get it now! I just bought my Skyrocket and my battery was completely gone in 5 hours without hardly using the phone. I'd used app killers and saw very little difference. I was ready to return my phone when I read about Juice Defender and installed it. From the first day it improved my battery life almost 4 times more. Now at 8 pm I still have over 30% of my battery left. Don't hesitate, download it now.
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.
Best App. Download & read the info. I have tried every task killer/manager out there. Along with hrs spent learning how to close all background & system apps that constantly run. This app IS NOT A TASK KILLER but is much better at controlling all the apps & the constant stream of data & sticky broadcasts. By doing this & explaining quite clearly how to use it totally transforms your phone & stock & background processes. Plus it instantly makes battery LAST LONGER on simplest of settings. ALMOST DOUBE DAILY BATTERY POWER. BEST APP EVER 10*
Impressive I've been using Android since the beginning, never thought I'd need this until now -- Galaxy S2 chews through battery like nothing I've seen. After half a day with Defender I'm already seeing a noticeable difference -- only about 20% down after biking with GPS, bluetooth and mp3 running, an activity that used to just about kill an almost full charge. Incredible!
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
- added per-network "keep enabled" for Location
- added per-app custom controls
- reworked the widgets, improved "user" control
- added Bluetooth enable/connect in QuickBox
- improved tablet/Honeycomb support
- better handling of the keyguard during phone calls
- removed read logs permission
- several fixes: night/peak schedules only starting the first time, Traffic bug, workaround for Bluetooth FC, AOSP on 2.3.7
- UI tweaks
