Juice Defender

seraj12 · May 2, 2011

I got juice defender yesterday because my battery life on my Galaxy S is rubbish. When it gets below 20%, it seems to start draining even more even when i have everything disabled and turned off. Im using the agressive setting on Juice Defender and it says when my battery gets to 15% it will start saving it more, but its not. Any tips on what settings to use because it is quite confusing?

Juice defender is bullshit, it can even drain your battery (in my opinion, but many others also think so). I've tried it on my G1 long time ago and it also drained my battery faster than without. Maybe you can try re recalibrate you battery?

For all Android phone owners with poor battery life, I will highly recommend you to try out Juice Defender on their phone.

I tried Juice Defender and Ultimate Juice Defender and finally decided it did not significantly improve my battery life.

Juice Defender is fantastic for some people, terrible for others. It depends on how you use your phone.

I tried out JD a while back and came away unimpressed.

This was from about a year ago:

My Galaxy S has been on one charge now for about 40 hours and is at 37%. About 22 hours of that 40 have been in flight mode. The screen has been on for just over 2 hours. I have been using Juice Defender with agressive settings. However, when i am actually using the phone, the battery goes down by about 3% every 10 minutes. Is this normal. It was 72% 2 hours ago and is now 37%.

For me it's been great.

I found that if I don't have apps starting and stopping (task killers and programs) and I leave my open apps alone, it uses less battery power.

Wow. Juice Defender does really work. At 11 pm last night, my battery was at 9%. 8 am the next morning it was still 9%. 4pm in the afternoon it was STILL 9%. However, when im using the phone, the battery seems to drain a lot quicker than before. By the way i am using the agressive settings.

This is about the best I can do on my Galaxy S device as well.
Juice Defender seems to make it worse.

I think it really helps when your phone is in standby and below 15%. But when i am using it it drains really fast.

sonofaresiii · May 6, 2011

Again, I think it depends how you use your phone. From what I gather, it mostly saves battery by severing connections when you're not using them. If you are a light user and regularly DON'T use your phone, but keep it in standby and only need new messages/updates every hour or couple of hours, you'll benefit quite a bit from not having it connected.
If however you're a frequent user, constantly using your phone for apps and want messages received immediately, you'll actually lose power from JD running so often and connecting/disconnecting.

At least, that's what I gather from it. I see the benefit, but I use my phone very frequently on irregular schedules and want messages received immediately... so JD was a bad choice for me.

My battery is really really bad when im using the phone. It was at 60% 3 hours ago. After 18 minutes of phone calls and 75 minutes of games it is now 26%. Is this normal?

jamoosh · May 6, 2011

It's normal for me on my Mesmerize.

jamoosh, i think you should give juice defender another go. Use the aggressive settings. Ive been using it 5 days and it really saves a lot of battery when you have less than 15% remaining. The other day i had 9% remaining and i didnt use my phone at all just to see if juice defender worked. About 13 hours later it was still 9%. So it really helps if you are expecting a call or something and dont want your battery to die.

SirVilhelm · May 6, 2011

I have the Thunderbolt and the first full day I went to 15% in about 5 hours. After using JD in advanced mode I got almost 14 hours on one charge. I have it sever all connections when the screen is off but it does re-enable wireless every 15 minutes to update messages, ect. So in my case I say it works.

jamoosh · May 6, 2011

I'll give it another go!
