[Q] Is there an app like Juicedefender?

Just went from Gingervillain to CM7 and Juicedefender is not working with CM7.
The feature I like about juicedefender is that it turns off my data unless I unlock my screen. Is there any app in the mean time that would do the same thing?

Yeah dude, check out Super Power in the market. Same concept.

Does that really help in battery life ? (Juicedefender) or any other app
Sent from my HTC Vision using XDA App

I used to use JuiceDefender on 2.2, but since flashing CM7 I haven't been using it and my battery life has been fine.
I have brought up in other threads that JuiceDefender only helps a lot when you leave the screen off phone idle for a long time. It doesn't really help very much turning the phone on/off a lot because the data connection costs you more battery turning the mobile data on and off over and over.

I don't use my phone too much for the majority of the day, so that's why I want the data off when I'm not actually using my phone.
In my opinion, it does get me more battery life because the data gets turned off and that way it conserves battery. But like that user said, it'll only be beneficial if you let your phone stay idle for periods of time and not constantly turn it on and off.

Task Manager

Which is the best Task manger? Should be good enough not to drain the battery in short time.
Thanks.

From what I read you dont need to use them I myself have never, just make sure you kill any games you play (if you do) they eat battery.

Task killers are bad because Android is designed to kill them when it needs to. The thing that drains the battery the most is apps running in the background, the screen brightness and if you CPU is being maxed out constantly.

No killing as multitasking is excellent on android; just make sure you press home instead of simply switching the screen off, apparently it leaves an application in the foreground.
The so called task killers are the stupidest apps evar made.

Yeah, don't bother.
Best way to save battery is to use a static wallpaper (not live wallpaper), turn off notifications for apps such as Facebook, Twitter etc. and only use WiFi/mobile network when you actually need it.

You don't have to disable internet connection when not needed as most of the kernels can easily get you in ~30hrs range with some tweaks regardless of it.

Because Android is designed to kill the apps!
Search the market and try them yourselfe.
We all don't use TaskKillers!

Thanks for this very complete answer

I know, I am a bit irritated, but I have a question : Why did the InsertCoin v14 rom have a Task Manager ?, (it comes from HTC Sense 3.0)

App for battery drain

Hi,
I am looking for an App that tells the battery drain in mv..
e.g at 100% batyery is at 4100 mv and at 75% is at 3600 mv...
So there must be some application that tells the drainage in reall time. So that we figure out impact of freezing applications..
Any suggestion would be highly appreciated...
Regards

Just use BetterBatteryStats first to see which app/service is the rogue one.

Hi, I recommend you to try Battery Monitor Widget
PHP:
https://market.android.com/details?id=ccc71.bmw&hl=en
It's possible to monitor various battery stats without the widget too, just check the options. (No, I'am not the developer, or someone related to)

What ROM are you using now?
Are you using a Live Wallpaper?
Also mention something you've done after which the battery drained faster... (something done after rooting)...

I don't know and im not using a live wallpaper.but when I rooted the first app I installed was set CPU and its on highest frequency,also when u finished rooting I remember that I entered cmw and flashed an update.zip which came by itself.could you please give me a battery saving ram?

I think its definitely setCPU. When i installed it my cpu freqquencies would change every second between min and max frequency(no matter what governor i used). The result:excessive battery drain
I think its because stock kernel doesnt support overclocking(or even underclocking)...May be the devs could explain it
After i did a factory reset, battery is ok now for me. No battery drain when kept idle for a night:good:
P.S. Also before reset my HW decoding(in video playback) wasn't working(now its ok)....any1 experienced this too?

The problem isn't setcpu the problem is that he set it to 2ghz

I think it is the setCPU too, try to use no-frills, it is a tad better in my opinion, but stock kernel doesn't like non-stock settings that is for sure.

I upgraded to rc2.1 cz they told me that the battery drain will decrease, but its still the same

how often do you use your phone and what operations do you do with it... are you always on full brightness? is your gps always on? are you always on wifi or bluetooth? some things to consider that may take chunks of battery life..

Always on wifi

you need to reset the battery by the sounds of it, empty your battery tonight, run some games or put youtube on or something....there used to be an app on the market that would run gps\wifi\brightness all max etc and empty your battery for you....not sure if it's still there.....but when you do root you can clear battery stats which will make your life easier....but yea empty it, charge it while it's off and HOPFULLY everything will be fine for you also as a sidenote, i charge my phone with wifi on and internet radio playing in the night and charges to 100% fine

When should I clear the battery stats?
Sent from my HTC One V using xda premium

it's known to reset the "capacity" of battery, but personally i don't believe it.
Use program BetterBatteryStats and see what's keeping your mobile phone awake, and also install CPU Spy to see on what frequency is your phone mainly working.

Not true, those programs are used only for troubleshooting, and are mostly deleted afterwards.
They helped me countless of times, so why wouldn't he give a shot?

Cyanagenmod battery life.

Hi guys,
I've had a less than impressive battery life after I had Cyanagenmod installed on my hox. I know it's the norm for the screen to be the highest consider of the battery. However as you see in the screenshot it's the OS. Is there something I should do?
I can lose half my battery life consumed in an hour of moderate use.
Help would be appreciated, thanks

Well in general aosp Roms use more juice than sense roms.. have you tried those? Before you do that though, have you checked what drains your battery with an app? You can also use greenify to hibernate apps running in the background
Sent from my HTC One X using xda app-developers app

Thanks for your reply. I'll try greenify, what app do you recommend to check which apps use more juice?
Sent from my HTC One X using xda app-developers app

Well I'm not sure if I can give any recommendation, but I use Gsam battery monitor (Something along those lines..)
There are alot of apps on the play store that do the same so just get one that suits your needs

I would advise against any app that says to improve battery life.
They scan for apps then shut them down, if that process didn't finished their task the os starts them up again only to be closed.
They do more harm than good.
I would suggest using a custom kernel and underclock/undervolt.
Lower screen auto brightness amounts.

Yes undervolting is also a good idea
