El Final! Read below for results!

I figured I'd post something (somewhat) useful (I hope?) here, since all I've done so far is bitch and ask too many freakin' questions :D

Alright, so when I was on stock I had to use JD (JuiceDefender) all of the time to make my battery life just tolerable, and it was still horrible. After updating to a revision of CM7 uploaded a few months ago (My phone is quite new, and it's my first Android, so everything was new to me at this point) I had installed JD.

After installing it, my battery life went six feet under and, once I uninstalled JD, it was back to what it was like on stock with JD enabled.
I had seen others with a similar problem, but this had been on an earlier revision of CM7, and I have left JD off of it up 'til now.

With the release of g60's CM7 rev 0.5 I noticed that my battery life was pretty stable. Here are my current stats:

screenshot-1336437815604.png


A little comment on this, I don't think 4% for Tiger GBA is accurate, but it may be when compared to the other stats... you'll see what I mean in a little bit hahaha.

As you can see, I have around 9.5 hrs of off-charger time. I do realize that the battery icon is in the charging mode, but that's because I just plugged it into the charger when I realized I should have taken a screen shot. After 9.5 hours of moderate to heavy usage my phone still had 27% battery (Like I said, you can't tell because of the charging symbol).

What do I do on my phone? Well, today was a school day, and my school is block scheduling (Four 1.5 hour periods each day, 30 minutes of lunch, 10 minutes of break in between each class [This includes before lunch]).

We do have wi-fi, but today it wasn't working for me and I don't get service in my school building, so I turned on airplane mode after first hour.

My life story:

Code: 
Without airplane mode:
1st Hour -> for the entire duration of the class, I listened to music and played Pokemon Emerald (STFU, Pokemon is a ****ing GREAT game!), no I don't pay attention...
Passing period->Tiger GBA running in background, music still playing, phone locked. 

After turning it on:
2nd Hour->Same as 1st hour, but on airplane mode. Yup, still don't pay attention.
Passing period->Same as last period.
Lunch->Skipped lunch, hung out with friends, listened to music for the entire duration of lunch, Tiger GBA for about half.
3rd Hour->Just music, needed to work on a design for graphics :D
Passing period->Talked to friends, no music.
4th Hour->Turned music back on, Tiger GBA time again, and again for the whole duration of the class lmao.
Done with school!
Off charger, airplane mode off, wifi connected to home network, idle mode for 2 hours. Connected to charger and took screenshot you see above.

Summary:

Code: 
1.5 hours of music and Tiger GBA. -> Wifi and service on, no wifi or service.
10 minutes of music. -> Wifi and service on, no service.
1.5 hours of music and Tiger GBA. -> Airplane mode.
10 minutes of music. -> AMode
30 minutes of music. -> AMode
15 minutes of Tiger GBA. -> AMode
1.5 hours of music. -> Airplane mode.
1.5 hours of music and Tiger GBA. -> Airplane mode.
2 hours idle. -> Wifi and service on, both wifi and service connectivity.

Total:
4.75 hours Tiger GBA.
7.3 hours music (Probably ****ed the addition up, not sure rofl).
2 hours idle with nothing.

(Music and GBA are both separate and together at different times, see Summary for more info on timing).

As you can see, I just about drained my Triumph with music all day and semi-drained it with Pokemon.

SIDE NOTE: YES, I LIKE POKEMON, OKAY?! I'M 16 AND PLAY POKEMON, SO?! It's a fun and addictive game! :(

Sorry for the info overload, I just want to make it clear that that's what I did today without JD on. I'll start over tomorrow and do the exact same thing but with JD enabled, and no life story this time because it'll be the same.

[TO BE CONTINUED AND FINISHED WITH RESULTS]

Finished!!!

Alright, here are the results:

CM7withJD.png


All I can say is wow. I did the same exact things as yesterday, except instead of idling for another hour I had to rush it to a charger, immediately before taking this screenshot, only because I had realized that my battery was completely drained.

After an hour less than last time, and I'd say even a little less GBA and an hour and a half less music (One period I was testing and didn't wanna grab my headphones from my backpack 'cause I'd look suspicious), I have ~5-10% battery level as I'm typing this, and my phone is currently charging.

The verdict? JuiceDefender doesn't defend jack sh*t, or at least not on CM7. In fact it helps to drain your battery even faster than normal. This may just be for me, but if you want my opinion do what most of the comments on this thread support and...

Don't throw JuiceDefender on CM7, if it should be used at all save it for a stock ROM!

Thanks for reading! Comments and suggestions on what I should do/should have done differently are welcome.
 
Haha, thanks, wow you posted fast o.O
I don't know if I cleaned stuff up by the time you posted, my apologies for a very messy read if you read it early lol.

EDIT: Forgot to mention, it should be fine, but I'm thanking you for feedback (Any and all feedback is great, helps me improve my posts), I hope that's not against any rules or anything.
 
I personally don't like JD... People have said that it can cause problems and not toggle data on or off properly (or wifi or anything really...). Also JD might cause more of a battery drain depending on how you have it set up. Say you have it turn off data when the screen goes off and and turns it back on when the screen comes back on. Well if you are constantly checking your phone it is going to be turning the radio on and off and consequently draining the battery.

Also you can thank people. There is no rule saying you can't thank people for posting feedback or even just for the hell of it.
[OFFTOPIC]And pokemon isn't something to be embarrassed about. I'm 18 and I still think it's a good game. Maybe they have kinda destroyed it, but it's still not a bad game.[/OFFTOPIC]
 
Personally, JuiceDefender Ultimate on GB MIUI has helped my battery life tremendously. I've gone about 15 hours on my current charge with moderate usage and still have 14% left. My record is 27 hours with normal usage (texting and browsing every now and then, with calls and Facebook in there too) and 30-something percent left.

I get those kinds of numbers by letting my phone go into a deep sleep.
 
ive personally never used JD, i was advised not to by many friends and a worker at a sprint store

all my friends had issues from terrible battery life, to no deep sleep mode, and a few others

and the worker at the sprint store told me straight up that if someone brings there phone into his store with a non-working battery and they have JD he Will not replace there battery for free due to the fact that he had seen to many people running JD that somehow kill there batteries


but then ive had other friends i think they were on verison or tmobile that when they brought there phone into their store for a battery drop issues the person behind the counter actually took there phone and installed JD on it for them

and ive read plenty of posts on here about JD working wonders, or not working at all, or stopping deep sleep mode



i myself have now become curious to whats causing the issue, is it just JD itself, or is it the settings certain people are choosing, or is JD reacting differently to certain apps which one user may have but not another lol

this thread has sparked and intrest in me lol ill be checking back here to see whats up


O and i personally dont run JD or any battery saver at all, im running CM7 tg-reloaded 3-25, and the max battery ive gotten was just short of 3 days since last charge, and that was 1 day of pretty minimal use and 2 days of moderate use
 
You guys are lucky to get up to three days lol. I only get like 4 hours. In the first hour I stream power 106 and browse the internet or go on tapatalk. The second hour I just moderately use it to watch a short video or two on YouTube. The third hour i text but not much and the forth hour I go on tumblr and my battery is done :D

well ive personally noticed if your running something like youtube, it uses your data and it also uses your phones video, together they cause the battery to drain massively

Yeah definitely. Im new to trying JD n so far I've noticed it helps a little maybe 30 extra minutes of what I used to get without it. I got the trial version though.
 
streaming radio should have the same effects, cause your using data, the speaker and audio, and small amount of video for displaying cd covers and whatnot, altho the phone has built in systems to manage all these things, just the multi tasking its doin while playing the music also causes battery drains

Yeah, after this experience I'd believe it, I think JuiceDefender is more of a gamble and depends on your style of usage on your phone, and I guess it was probably built for and tested on stock.

Thanks, just making sure thanking for reasons like that was allowed before I did it any more.

I was more or less joking about pokemon, but I do feel like people have total misconceptions about it, after all it's just a game :D
Agreed about the destruction of it, I'm still playing Emerald even though I have White for my DS. Something about the older ones lol.

For those of you that wish to know what settings I'm running JD on:
It's the trial version, set on Aggressive with communications shut down at 15%.
Notification enabled if that even matters. Everything else at default.
Newest version, I like to keep my phone updated.

I realize you can probably get more with optimal settings, but this was to test the affect JD has on the average phone's battery: the average phone user doesn't fine tune their phone like all of us do (As hard as that is to believe). Then again, the average user doesn't even know what Cyanogen Mod is, so there's that...

My phone never goes into that state (deep sleep) how can I check what's keeping it up? Thanks in advance

Try turning off autosync and lock your screen for a minute and see if it goes into deep sleep mode. That's what it was for me. Whenever I wanna check my mail, I just go into the gmail app and hit refresh. Not a big deal for me if it'll significantly improve battery life.
 
In my opinion, JD is only good for particular types of phone users:

If you (like me) are the type where your phone stays in your pocket most of the day except to answer the occasional phone call or respond to a text message, JD works wonders (I've gotten as much as 4 days on a charge running MIUI GB).

If you read ebooks, play games, listen to music, surf the web, or are otherwise a heavy user of the phone during the day, I can see JD doing more harm than good since it consumes resources itself and can needlessly switch off resources in use.

nope.

I think the majority of smartphone users try to use the device to its potential.

the small group of people that use it like you do use it that way becuase they came from normal cell phones, generally the older group.

personally, my phone is a gps device almost ALL day, as well as playing music, and very often web browsing to find information I need. (not facebook/socialnetworking use)

in my personal use-case. I decided to not attempt to even use any battery saving apps. I just use my phone to its fullest potential, regardless of battery drain. I have it set at 1.6Ghz.

I also have like 3 or 4 fully charged batteries on me at any given moment, and i swap at least 2 in in the course of a day, and charge them all at night.

gotta tell ya, its a world of difference when u know u have multiple batteries as opposed to constantly having that little thought in your head everytime you use the phone if it will die before you get home. that was the WORST feeling and it was something no one should ever feel.

its a phone, its designed to be a tool to use throughout the day to accomplish many small tasks. the last thing it should do is cause any worry in your mind. if every time you pull your phone out of your pocket, you think to yourself if you really NEEd to check the phone and if its worth draining the battery for that moment, just buy some extra batteries and relieve your mind of that thought.

small things u can do to be zen through the day :P and the little things add up
 
Thanks for doing these tests, I have been wondering just how effective JD is lately. However I have some questions about your methods and reasoning.

first of all it seems that about an hour or two into your day you charge your phone for a bit (as evidenced by the slight increase in each screenshot) either that or your phone has been blessed by Thor. However when the screenshots are compared side by side it seems that you charged it less on your juice defender day, not by much but noticeably so.

Second I see that you spent much less time in airplane mode on your juice defender test (as evidenced by tiny blue bar under your battery graph. JD is not equivalent to Airplane mode and obviously between the two, airplane mode is much better for battery life and the closest you can get to airplane mode in JD is Sleep hours where JD does not turn the radio on for a specified amount of time which i don't think you can do in the basic version. Also i assume you only have the basic version based on how close together the blue signal bars are when your phones screen is actually off, in the paid versions you can increase the amount of time JD waits between activating the radio and how long the radio stays on.

Third in your tests I can see that the only time JD is actually doing anything is when your phones screen is off and it periodically is activating the radio for data sync (because this is JD's main feature). this is only happening for about the last hour or so of your JD test. it would be more helpful if you actually had your phones screen off for a longer period of time so JD could actually work longer and we could see a more defined result.

Essentially what i'm trying to say is that I'm questioning your use of the scientific method in this test, JD basic mainly only disables the data radio when your screeen is off, so when you have the screen on for most of the day JD is doing nothing. Also for someone like you who has their screen on for long periods of time I think that your earlier plan of using airplane mode is more effective. I use JD because I need to get texts and calls during the day and thus Airplane mode is not an option for me. Just some helpful criticism, and my 2

Sure, if that's the only device they have access to. Potentially a valid point.

Lol, I'm only 27 - don't know if that's considered old. I use my phone the way I do because I am a software engineer, so I sit in front of a computer + various other web connected devices like my tablet all day, thus reducing the need for me to pull out my phone except for "phone" tasks. That being said, I do depend on it for those moments I am away from the desk and need to look something else, but that may be fewer and further in between than most people. (It is nice to know my battery isn't being sucked down rapidly while it idles in my pocket though).

i definately know what you mean.

for awhile my phone was my ONLY device but now i got a powerful desktop i use for designing and compiling and rendering and im in front of it alot and i pull out the phone less.

but on field days where im out and driving, where the phone is the device with me, yes its my everything.



and with my first statement, i said "most users TRY to use the device to its potential" i know it doesnt apply to everyone, but the fact of the matter is the average person doesnt willfully buy a "smart phone" with the goal of only making calls on it. which means most will at least try the other features and more often than not the phone becomes the mp3 player and gps navigator and web device when mobile.
