Juice defender, yay or nay?

I'm getting 1.08x, is juice defender worth keeping for that? Or no? Thanks on advance.

Yay.
I get 1.35x on default profile while using Myn's RLS5
Back when I was on fresh I used to get 2.20x with the aggressive profile.
Battery almost lasted 24 hours with very light use.
With Myn's, it last 17-19 hours and I am willing to sacrifice the extra hours for the performance.

Are you using the Ultimate juice or just plain juice? I want to upgrade to Myns 5 but I don't want new radios.
Sent from my PC36100 using XDA App

Yes I am using ultimate juice. If I remember correctly, you have to upgrade all your radios when you switch to a 3.70 rom.

I need to get ultimate but I don't pay the bill so I have to work around it. I wish I could just use paypal to buy it -_-'

I was trying JuiceDefender, but didn't really see what it was doing over Tasker and CPU Tuner and/or smartass. It seems to me that with Tasker doing WiFi and CPU Tuner to either do CPU profiles or just setting to smartass that there wasn't much that JuiceDefender added.

You can do almost everything juicedefender does with tasker and cpu tuner if set up right. Tasker is a little harder to use (though does have a lot more capability). Basically juicedefender is an alternative to doing tasker and cpu tuner not something you need in addition to. Basically with ultimate you can manage screen off cpu speeds, turn mobile data, wifi,4g on and off by screen schedule and or an app being active.
Personally i use juicedefener (ultimate) i get around 1.8x on CM 6.1.2 and about 2 on fresh. it will all depend on your settings and how often your screen is off. I go several hours at a time where my screen is off then ussually use it for 30- an hour between breaks and has greatly increased life because of this i say ..... YAY

Before I rooted my EVO, I was using JD Ultimate and the most life I got outta my phone was 1.90x but that when I didnt use my 4G and Wifi. When I would keep those enabled I would get about 1.25x
Now that I m rooted, I get about 2.30x avg. - Again though - I don't keep my radios on all the time, I only use my Wifi when Im home and I hardly ever use 4G. I live in houston and the signal here is good when you are in the city - but where I live - I sit right on the edge of good and bad signal and it makes my phone VERY laggy and choppy b/c its constantly connecting/disconnecting from the 4G network.
I would go ahead and upgrade to Ultimate cause its worth it...

can't live without juicedefender, period. Android is crippled without it -- Google should seriously consider integrating this fucntionality into the standard OS.
Without JD, my phone is completely DEAD by lunchtime every day (~5-6 hours after unplugging in the morning). Everything is set to sync automatically, of course, so it's there whenever I pick up the phone. With JD, I still have battery at night before I go to sleep. In fact even if I forget to plug the phone in at night, I still have some (very little) juice in the morning. When the battery gets below a certain percent, it goes into super-duper conservative mode and will NOT let the battery die. My counter only reads 2.15x but I'm sure it is actually much much more than that.
I use the most up-to-date beta version with ultimatejuice, but I don't really use all the features of the paid version (I still manually toggle wifi when I am at home because that is the only place I use it.) Just remember every time you update JD you need to open up the app and re-enable it so it starts working again..

I say No Juice. Running with the stock HTC kernel, I can go 24hours with moderate usage.
To me moderate use is:
1 hour of talk
50-100 texts
2 hours of gaming (bubble blast, gun bro's, bubble blast, ect...)
30 minutes of web on 3g
30 minutes of web on 4g

On the fence
I found that juice defender did help improve my battery life a little bit. But I'm still kinda on the fence about it. At times it messes with your data connections (3g, 4g, wifi) and things like gmail and calendars are not able to sync. Not too big a deal but I'm just not sure I like it yet.

So is that a yay or a nay? Also for 1.08* is it worth it?

Battery life is horrible, yet not much is running?

I have my cpu settings on 245 245 powersave when the screen is off, yet I'm still getting horrible battery. I use my phone extremely lightly, maybe once in a while to listen to music. Check my emails, chat every so often. I use to get 48 hours with light usage. Seems I cant figure what is causing my battery to drain. I have a craigslist app, I had one search enabled so I deleted that to see how much it will effect. Does google talk drain that much? In the past it was fine. My usage shows the 2 main ones are cell standby and phone idle. Any tips on finding out what exactly is draining my battery? Im running CM 7.0.2??, latest stable, forgot. Koni's was the same. I thought maybe sense drained the battery, but it doesnt seem to be the problem.

Click the link in my sig and run that battery conditioning routine for one. What kernel are you using?
And dump SetCPU. Useless app, seriously...

1. Update to the latest stable version...7.0.3.1 released this morning.
2. Google talk could be draining, but I've never used it
3. Perhaps install it under a clean install and see if that helps.

Get tge system panel app. It'll show you what apps and everything that's eating your battery. Does the kernal your on perflock unlocked for over /under clocking cause if it isn't setcpu doesn't work.

+1 SetCPU is great for Sense ROMs, but not necessary for CM based ROMs.

looks to me like you were in pretty crappy coverage. that makes the phone work hard. it's justifiable that you'll have a lot of battery drain then, even while sleeping.
you can greatly reduce this by:
1: upgrade to newest cm7
2: flash a custom kernel. may i reccomend tiamat 4.0.1?
3: put your governer on smartass, and uninstall setcpu. smartass does it better.
4: use a bsm from viperboy. they decrease voltages. work almost too well.
5: USE JUICEDEFENDER! this will save a ton of battery in low coverage, because it turns off 3g when screen is off. this still lets you get calls and texts, but with mobile data off, your battery will last much longer while sleeping.

what prl are you on?

[Q] How to get longer battery life on Deck's gingerbread-evo-deck 1.2.1 Rom

I was wondering is someone can help me. I've been using Deck's ROM's for the HTC EVO 4G for some time now and I hear about all these guys getting 20-30 hrs of battery life. I'm currently on 1.2.1 and have never got probably more then 11 hours out of my battery life with heavy or mederate usage. I've updated all my radios, wimax, etc....I've tried different kernels, I've installed vipermod and undervolted, I have CPU profiles. I've installed a new 3F3D driver. I've tried the wake lock fixes and still nothing has changed. Am I missing something here to how these other guys can get that performance out of their batterys. I'd like to post this directly to his thread but this is my first post and I guess I need at least 10 posts. I'm a bit of a noob but can hold my own.

I run decks with tiamat kernel 4.0.5 and I get outstanding battery life. Give this a try then let me know how it works out. Check your accounts to see if anything is synching that's insignificant. Then check your apps update frequencies. Lastly, turn off all of the haptic feedbacks, animations, and effects. Live wallpapers kill a lot of battery too. You might also want to try enabling and disabling auto brightness to see which is more energy efficient. If your overall goal is great battery life, then a lot of the bells & whistles are pointless.
It is nice to be important, but it is more important to be nice.

I've tried tiamat 3.3.7, 4.0.5, and 4.0.6 and have got the same results with all three. I've tested each and one of these over about a week period. Currently I am trying SavagedZen 2.2.1 and up til this morning it hasn't changed much. I've took off all auto syncs. All haptic feedbacks, animations, and effects have been turned off. Never use live wallpapers and have read that lighter wallpapers will conserve battery. Right now I have auto brightness off and down to about 35-40%. I did however just checked off data enabled about 2 hrs ago and seem to have got better battery since. So far I'm at 82% with about 4 hours of moderate use. (mostly texting and surfing the web). I didn't know if there was any other tweaks internally that I'm missing or if it's more of a puzzle with what combinations to use.

Just saw my background data was enabled. I unchecked that as well. We will see how this goes I guess.

It seems like it's definitely data related. I downloaded skype from one of the forums strait to the phone and my battery percentage went from 79% to 68% just for the duration of the download. Is this common?

Do you use an SBC kernel? Have you whipped battery stats in recovery? Have you tried using the kernel governors (smartass, powersave, conservative) without setcpu?

I have used kernels with SBC and without and haven't seen much difference besides the initial 10% loss of battery. I usually I wipe cache, Dalvik cache, and battery stats everytime I flash a new ROM in recovery. I usually do a factory restore too. I've used smartass and savaged zen as governers as well. Currently I'm using savagedzen governer with a max at 1036 and a min at 245. I also calibrate the battery when i flash a new ROM. Currently I'm standing at 60% battery with about 7hrs and 37 min on battery. Probably the best battery life I've seen. I'm still seeing massive drains when I use 3G. I was just on xda forums on my phone for about 5 min. and the battery went from 65% to 60%. If I turn 3G off it stands idle for awhile.

I'm scratching my head trying to think of what will help. You probably won't like this, but when my rom has me stumped with a problem, I wipe and start over. Maybe an extended battery is the answer? They are dirt cheap for the EVO now.
It is nice to be important, but it is more important to be nice.

Yea I was thinking about an extended battery as well. It seems like taking 3G off does wonders for the battery. Are you keeping yours on or off to get great battery life?

Lowering your max and min cpu frequencies will improve your battery life. I've always used 128 MHz as a min with no ill effects. Ever since I got my evo I've kept the max at 998 MHz and it was plenty fast, but I am currently trying out 691 MHz max and it seems just as snappy so far (battery life was great at 998 MHz max for low or moderate usage, but with heavy usage I've noticed it drains too fast). I'll probably try out some lower max frequencies to see how low I can go without affecting performance.

Use JuiceDefender to automatically toggle your data connection (3g/1x) off when the screen is off. This will dramatically improve your battery life especially when you're in areas with poor signal. If you want, you can set it to turn on the data connection at user-defined intervals so emails, google voice, and anything else that needs a data connection to be refreshed periodically can go through. With the paid version, you can even allow exceptions for programs like google music, pandora, or wireless tether, so they can keep the connection while the screen is off if they're in use.

Ill try juicedefender. I had it before but didn't really know what settings to use. Current battery is doing well. I'm curious to if all these people experiencing 20-30 hrs of battery life have data turned off a alot. I'm currently at about 14 hrs. with about 42 percent left. Thanks for all ur advice.

I can easily get over 40 hours with light usage and over 20 hours with moderate usage, but that's only because of JuiceDefender. Without it, my battery drains like crazy at work where there's really bad reception.
I use the customize profile with mobile data enabled, schedule enabled at a frequency of 30 min, and apps enabled when the screen is off for google music, pandora, and wireless tether. I also enable the text notification which puts the icon in the status bar. I've run into problems when I disabled notification where JD gets shut down in low memory situations, but having the icon in the status bar prevents that. I leave wifi, location, and night mode diabled, but that's just because they're not useful for my usage. I'm sure the other profiles work fine as well, but I just like knowing and controlling exactly what JD is going to do.

Try using saveged Zen with conservative governer, viper mod and other little things people have mentioned

I'm going to run JD all day today with those settings to see what it does for battery life with my data on. Yesterday seemed to be the best battery life I've recieved with data off for the majority of the day. Got about 17 hrs with 39% left. I'm happy with that. If JD can get me something like that without having to toggle with data on/off that will be nice.

I've run viper mod with tiamat before and undervolted 50mv with little or no change in the overall performance of the battery. Any suggested settings for savaged zen using viper mod?

Undervolt as much as you can, all phones are different. As for jd, sorry I forgot about that. It's a HUGE improvement. Your battery can pretty much double. It can be a little annoying in some cases.

Didn't really get to do a full trial on battery life yesterday. I downloaded a Sense Rom and tried some troubleshooting that I read on Deck's page but it didn't work. Today will be the first full day I try JD with 3G on. I will probably try viiper mod tomorrow after the results I get for today. Thank for the help guys.

You can't judge in one day.. you have to wait like 3 days of use to let it settle down
Deck's + SZ + SuperCharger script + ViperMod script.

I believe I have found what i belive is just about the perfect setup for this ROM
My evo is lightning fast, in app performance is almost comparable to my xoom
And with heavy usage my battery lasts at least twenty hours
Kernel: savaged Zen 2.2.1 bfs
Setcpu info: Max clock to 1136, try 1152 if 1136 is stable for Max clock, min 245. Savaged Zen governor, screen off profile with interactivex governor and min bumped to 384mhz. Eliminates all screen on lag
Market app: chainfire 3d its a graphics driver that increases all animations, 3d effects efficiency and speed, and improves battery life IMO follow in app instructions and install the driver, make sure to nand backup first and to not have the phone connected to the charger or computer when installing
Market app: battery calibration wipes battery stats to build new ones that are correct for your ROM kernel setup
Advanced setting in settings menu: performance settings, VM heap size set to 48
Market app : SD booster set SD cache to 3000 makes all SD apps and media faster.
Market app : busy box install 1.18.4
After all this install any user apps you wish and run fix permissions in ROM manager or recovery
Its a lengthy setup, but there is much profit to be had. This setup is faster then I've ever seen an evo run and has the best battery life of any ROM kernel combo I've tested.

[Q] Phone getting hot after few minutes of use

Been noticing this since last week. Every time I use my phone for like 1 or 2 minutes, the phone starts getting hot. Usually, it gets hot after an hour of use (Facebook, Messaging, Browser, Twitter, Play Store). Went to Performance settings in Settings, then Processor, and notice the Current CPU frequency is always at 1000 MHz, then goes down to 200 or 100 MHz when idle for a few seconds. Switched between conservative and ondemand governor, no OC. Was on PA 2.54 when this happened, but I'm on CM10 Stable now, and it's still getting hot after using it for a few minutes.
This hasn't happened to me before. Not sure if this is normal, but I just want to make sure.

My recent heat and battery drain was coming from an app. I didn't check the CPU.
I checked the battery area of the settings and found a locale add-on that was draining more juice than my screen.

It will happen if your signal is real bad or 3G is down in your area.

I don't think it's my signal. I get 2 or 3 bars almost all of the time at home with the FC09 modem.
Besides opening and/or using an app, it seems that the CPU clock will go max speed if I do something, such as scrolling. Battery is also draining quickly before this was happening to me.

I think that's a Jellybean-specific CPU behavior (to keep system flowing like "silk", JB put CPU at max the instant you have your finger on screen... At least that's what I heard). Try ICS/GB ROMs and see if problem persists.

Yeah, you're right. I even looked it up. It's part of Jelly Bean.
I'm going back to CM9 or The People's ROM.

You could try a different kernel, or lower voltage. Sorry not sure what phone this topic is for lol but that's some options. It takes a lot to get my phone hot, and I'm on jelly bean

You likely have an issue with your settings.
If it's not an app, you probably have an issue with your performance settings.
Try turning off some of the eye-candy features in the settings. This will likely include the Cyanogenmod specific setting area as well.
That should at least help.

It didn't help unfortunately.
I flashed CM9 earlier and the issue still exists. I'm now back on CM10 (11/22 nightly).
It's okay if this can't be resolved. I am probably gonna go back to a GB ROM.
EDIT: Issue still persists in GB. I'm guessing it could be a hardware issue? I have no idea. Back to JB. I'm still willing to try anything to resolve this. Thanks to those who posted some solutions.

[Q] Tips on Improving battery life in Airplane mode?

I use my mostly as a media device, but since I'm always near a wifi connection either at home, on campus or whatever, I also use Google Voice and Talkatone for free calls and texts and it works great. I also got two brand new Anker batteries and an external charger and they work fine (my old stock battery swelled and was just overall dead). So I'll use my phone in Airplane mode with Wifi on and I get around 22 hours with 90 minutes screen on time, which is decent, but I feel like it should be better than that. Depending on the ROM, I have gotten as much as 40 hours battery life (which is great) and as little as 14 hours, and this is ALL on Airplane mode with Wifi toggling, so I'm guessing its software/settings related.
i am on a new ROM as of yesterday so I want to make sure I have my settings the best from the jump. I turned off all Location services, screen brightness is low and with the exception of push gmail and google voice notifications, the shortest polling interval time I have for any app is 4 hours. Any other settings I can change to maximize battery life?

One thing you can try using gsam battery monitor to see of anything keeps the phone awake when the screen is off.
You can hibernate apps with greenify and can use dsbatterysaver to kill data on screen off.
Edit: you can also use Romtoolbox to lower max CPU speed to 800/1000mhz and set governor to powersave/conservative depending on the kernel you're running.
Tegrak can help undervolt but the app is a paid app. Romtoolbox has a free version.

To OP:
tt281gt has some great suggestions... I had an issue with conservative governor causing my flacs to skip. I was also running at 1000mhz. I changed to pegasusq and it was good to go. At one point I was using one of Kobridge's tweaks.I think it was Placebo2.0 It was the one where you had to pick like shift1,2,3 or 4 . Shift 3 had some great mods for the conservative gov. It was still great on battery but lost any laggyness. I know he has newer products that might be better than that. Maybe you can hit him up directly with your scenario and he can point you in the right direction. What your asking for is right up his alley!
