After a second look... JD is by far the most advanced battery saver out there right now. But the UI is starting to show it's age. With the help of a better interface and perhaps some better written descriptions of the various functions it could be a lot better. The real reason I stopped using JD was the fact that it was USING more battery than it saving me. After installing Better Battery Stats you can clearly see that it is consistently waking the phone up in upwards of 1000+ times a day in my case.
Really good app that could be great with one fix On my Galaxy Nexus it let's me get through a full day of moderate use while at work. Before installing the app I would typically plug my phone in several times a day and still be leaving the office with a red battery indicator. It also seems to keep the phone cooler as I don't seem to have a "hot pocket" anymore. Would have given 5 stars but seems to have issues with MMS.
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!
This is an awesome add-in! I have never found an app that works so well at controlling my battery consumption! As we all know, smartphones consume a lot of battery power, especially if you like to actually use the features of your phone. And I like to use everything and all of the time! This app does a remarkable job of managing my downtime and maximizing my battery life! I love having the freedom of not having to remember to turn off wifi or Bluetooth. I can even leave GPS on without worrying. I highly recommend it!!!
Most important android app This app is life changing. My Samsung skyrocketed would usually die around 5 PM after being charged all night. With the free app it lasted much longer, so u bought the ultimate version and now my phone lasts 24 hours and more. It is like buying a spare battery for 5$
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.
