Juice Defender

Thanks, aysiu - I looked at it and decided that - for the price of a cheap lunch - I'd bite. Hitting the learning curve now, but one quick question...

Do you think this can do everything that Juice Defender can do as well? I was thinking Tasker can either replace JD, or I can have Tasker invoke JD when AC power is disconnected.

Pretty much anything Juice Defender can do, Tasker can do, and Tasker can do a lot more, too.

I actually like the way I've set up Tasker better than I had Juice Defender before. When I used Juice Defender, data would turn off when the screen turned off and turn on when the screen turned back on. Sometimes there would be a slight lag in reconnecting. So if I wanted to check something, turn off the screen, and then check something again a few minutes later, I'd have to wait every time for data to reconnect. So in Tasker, I set it up so that after the screen turns off, it waits ten minutes. If I haven't turned the screen back on again in ten minutes, the data turns off. Otherwise, it stays on until the next time I turn the screen off again.

In my opinion

JD works if you do not use your phone very often. Like if you only check certain things each day and are not a heavy user.

If you are constantly using your phone and turning the screen on and off multiple times throughout the day, then it probably is not very effective for you.

Since some people turn the screen on and off many times, it actually uses more battery to find and connect each time the screen goes on and off and back on again.

But if you do not use your phone that much, having the service off and only letting it check when you set it up, it works like a charm.

So, heavy users, I think, will not see a big difference.
If you are light to moderate user, then you should see some changes in battery life.

Just my opinion......from reading everything about JD.

Just as an update, it's almost 11:15 AM and my battery is at 97%. So over 3 hours and it's dropped just 3%. Granted I haven't done anything heavy with the phone yet today, I have sent a couple text messages and downloaded a couple of app updates from the Market.

I also should mention that I am using the 2150 battery, I should have mentioned that in my original post. The bottom line is that I have never had this much battery left over 3 hours later. And that's with similar usage. So the app is definitely doing its job.

where did you get a 2150 battery? are they available for the skyrocket? another question- i have the free JD, i just set it to aggressive settings. will that help w battery life?

General Settings are the best settings. Once you turn it on and if you leave your screen off for a while (if your not using it) it turns off the data, and that saves you a shit ton of battery life.

Here's my setup. I've only had this for 2 days, but it seems to be doing quite well. I'd like to see how it goes in a week.

1. Bump charge in the morning
2. I have Y5 for my wifi when I'm at home
3. Juice Defender beta on basic setup
4. Watchdog Lite for rogue apps
5. Amazon MP3 Monitor connection unchecked, and force stopped (based on thread in this forum)

I'm a heavy phone user/geek and so far I've noticed decent battery improvement. I also plug in when I'm in the car to get more for the rest of the day, sometimes at the office. But, with the above setup, I'm curious how it goes with straight battery use.

with both juice defender and watch dog lite, should i kill them when i go into task killer or leave them running?

i have been using JD all day at home on wifi. since it does not look for the LTE signal while on wifi i noticed significant gains in battery life. and if i'm right when your phone is off it also does not receive the LTE, hence stronger battery life.

i'm a newbie to android so please correct me if i'm wrong.

i also noticed if i "back" out of an app as opposed to hitting the home button, this closes the app. i had been exiting app hitting the home button.

quick question- should i use the google email app or the one that came pre-installed and log in my gmail info there? my main concern is battery life.

Quitting apps doesn't really matter, since unused RAM is wasted RAM. Cached "running" apps aren't really running in terms of affecting CPU.

All I can say is I've let it be configured as it was as it installed, and I'm getting 36 hours per charge. Before Ultimate Juice (the paid version) I was getting only about 16 hours. I'm very happy with the battery now.

So do you recommend the beta version or Ultimate Juice ? What are the advantages of UJ compare to the free JD ?

I cannot find the beta version in the market. Is it still available ?

Yeah, and also for people who might take long breaks in between use. So I will use my phone a lot in the morning... then it will sit in my pocket or on the desk for hours then I'll use it again at lunch.. then again while I'm waiting in a line somewhere or something. So if you use the phone in concentrated spurts then don't use it for long breaks.. JD works great. For me I get about 1.8x battery life with JD. Sometimes I start to think that JD isn't really doing much and I turn it off or uninstall it... but then I can't make it through the day because my battery drains too quick... so I re-install. I've been using it for a while now and at least for me... it makes a huge difference.
