Principled design, sound implementation Well conceived, with many hidden bits of well thought out rules and tweaks. This app has impressed me more as I use it more. Take time to read the documentation and understand its operation. I found the 2x1 widget informative on the current state and battery savings. I am happy to have paid for the mid-grade version, though the basic settings of the free version seem more than adequate most my needs almost all the time. Keep up the good work, folks.
Top 3 essential app! I bought this app because my data connection gets stale and has to be googled off and on again before I'll get any data back. I wanted something that would automatically turn data off and then on again when the screen was active, but not turn off data if it was in use. The battery savings was just a plus. This app is everything I hoped for and more! Easy to use, and works very well. Go for either plus or ultimate. You won't be disappointed!
Definitely worth the $ Had the free version but had to upgrade to really save my battery. The only complaint is that the apps I've configured as "disable" don't seem to be disabled. Still give it four stars but ever since one of the many updates Samsung issued for my Verizon GS4 (I forget which one), the location Wi-Fi disable and the night mode features don't seem to be working.
Issue after Kitkat update on Nexus 4 After upgraded to Kitkat on my Nexus 4, Juice Defender wasn't able to properly turn on data (both WiFi and 3G) with schedule. Screen on will definitely turn on data. But when my phone was idle I won't able to retrieve any message at all as I configured Juice Defender to turn on data every 15 minutes. It's a great software and I had been using it for quite some time. I hope developer can fix the issue.
Mike, Moto e running 5.1 I've purchased the Ultimate version of this app and this version, for 2 phones on android 4.4.4 with different gmail accounts. Both versions worked really well & were reporting 2.08x battery life saving, also i was charging my phone less often, so was saving a lot of money on the electric bill. So is the app price price worth it? YES, it paid for itself quickly. But, now it doesn't seem to run on android 5.1 and doesn't seem to have been updated, that's a shame.
Excellent method of saving power! This program does what it says it does and more! My phone, the LG Spectrum, has an awful battery. On a full charge and with only 5 hours of up time, it was dead by 6:00PM. After downloading juice defender, I got more than twice the battery power. Its so easy to use and works like a charm, especially when comparing it to its competitors like Power Manager. The free version packs a lot of great tools, but I recommend upgrading to at least plus.
