[Q] Doubles Battery Life: Data Connection Switch in ROMs (like Juicedefender)?

Hi all,
i've been using Juicedefender lately.
FYI, Juicedefender lets you toggle the data connection (3G or Wifi) based on certain conditions (screen off, timeout, traffic/time ...) and do periodic data syncs.
I did this because i found out that the data connection is one of the biggest battery drainers. I was right: With casual usage over the day, my battery life at least doubles!
But the Juicedefender app has a really terrible UI and all, so my suggestions is:
Why not integrate this functionality into some ROMs? This would greatly improve battery life and could be a really slick functionality!

Why should it be integrated? Custom roms are made to give the owners of a phone the choice to change their device. If the UI of juicedefender isn't very good, maybe someone could make another one.

... because this is a system functionality which could be integrated into a ROM much more elegantly than with a regular app, IMHO.

Why would you integrate something that's based on personal preference? I'd hate it if my phone wouldn't sync my social media and mail when the screen is off.
It's common knowledge that the data connections are the biggest battery drainers by far, and there are plenty ways and apps that help you manage them already.

jesus people, calm down! i'm not saying that it should be FORCED on people or that i shouldn't be an optional flashable part.
but the available apps are only able to do it in a very rudimentary way (by changing the apn name to bull**** e.g.). i'm just saying that a nice ROM support for something like this would be great!
btw: you should try the periodic sync! do you REALLY need constant sync while the phone is in standby? if no - and you can live with syncs every few minutes - you will greatly improve your battery life!

Disagree to your opinion about JD. UI is great for me. Maybe you don't know how to use it.

The part in bold highlights what peeps here who disagree with you are saying. Because you want this in a ROM doesn't mean everyone would. I for one would also want data sync in standby, never mind the battery drain.
I understand your point though, that it could be an alternate ROM or a flashable zip. But then why bother when, as mentioned above, there are a myriad of apps that already do this?
Maybe you should have a poll and if it's wanted enough, one of the ROM gurus will consider it?

Try SuperPower if you don't like JuiceDefender. It does not use APN renaming and provides a lot of options (including 2G/3G switch which saves the battery even more than data)

JD UI is crap for sure. Switching to EDGE instead of 3G will improve your battery life by give or take 50%.
JD would be great if schedules would function properly, but since it causes issues with HTC mail for example, it is not an acceptable solution. I will not bash your idea since Desire HD has implementation of power saver in It's settings. No one forces you to use it even if it was implemented. Fcuk social networks, cellphones serve for you to be accessible. With battery life of about 10hrs, you aren't. Most of the time at least.

[Q] CoreDroid HD 5.3 battery life

Gday,
Just wondering If I could get some round about figures from you guys that are using combinations with latest 5.x Coredroid Roms and radios on what your general battery life has been like.
I ask for round about figures e.g. percentage of battery decrease per 30 mins on dependence of phone usage because I realize how much battery life can be affected by many different variables.
My setup is:
ROM - CoreDroid HD 5.3 (full wiped and non-titanium app install)
Radio - Radio_12.48.60.23U_26.08.04.07_M3 (Given 2 days to take effect and so far best 1 I've used)
Auto Brightness
Have gone back and forth between live wallpaper and wallpaper but didnt notice much change
Screen animations all on
I'm now in the process of the battery calibration found on Hemorrdroids.net. I was getting about 5-10% battery drop per 30 mins with mobile network on, auto sync on and moderate usage (mainly browsing xda and web + facebook and emails).
So I thought I'd give the battery calibration ago just to see if I can limit the drain a little bit more.
So any other figures provided would just help me to work out if Im on par and Im definitely getting the most out of my battery

With my desire hd with the 12.48 radio and cm7 it takes much less than with core droid 5.x i dont know how much less but a lot........

Yeah I've heard that about CM, I guess you can put that down down to the drain that htc sense causes.
I would switch to a non-sense rom such as cm7, But I still prefer some features of sense.
I guess I have to make a bit of a sacrifice to get those features

why don't you try mikes revolution rom, its with android 2.3.3 and sense 2.1?

Yeah I did and I found I was getting fairly similar battery life with coredroid, So i decided to stick with coredroid because I prefer the visuals and the performance seemed very similar for me as well

Oh ;-)
Then try an alternative launcher on cm7 like spb mobile Shell ;-)

Try these!
First, You need to turn of auto sync, just back up or sync by manual.
Second, Remove account of HTC facebook. It's always sync therefore it drain battery fast.

Turned off auto sync a couple of hours ago after my battery calibration because I knew it was a contributing factor haha cant believe I had it on.
Am yet to remove my facebook account because I dont no if I can do without that synced haha .
It probably would be wise to only update manually

I use extended controls (might also be possible with widgetsoid) to quickly switch to GSM only when I'm not using my phone out in the wild. That and turning data off when you don't need it (easily done from notification settings screen) will save a hell of a lot of battery over using 3G/auto with data on.

extended controls is a brilliant tool!
It often helps me, too

i think the same.. extended controls are cool for control a good batery drain... and in addition i have WIDGET ON/OF by pedro maicas (android market) for cut the 3g conection
for the flip and clock for example...

[Q] Best ROM to use with a 3500mAh battery

Subject says it all. I'm using Virtuous 3.2.0 with a stock kernel, and it just sucks the life right out of the battery. Plus, when I unplug it from the charger, it instantly drops to 96%. Any suggestions? I'm not a n00b to this stuff, just recently stumbled onto this forum and registered 5 minutes ago. I've also used Cyanogen 7 with the same results.
I like the Sense layout, so is there any "stock" deodexed ROMs that have good battery life?

Ok I lied. I am a n00b when it comes to kernel's. Don't know anything about them, or what they do.
I tried one with Virtuous., and all it did was force reboot every minute or so, so I went back to the stock kernel.

Uber kingdom !

First of all, all phone/ROMs/kernels/everything drop a few percent immediately, and for amazing battery life, I used the 12/23 incredikernel. If you are looking at 2.3.3 you can only use the kernel that comes with the ROM. I got about 8 hours of moderate/heavy use out of it today.

I've found that SkyRaider and using Chad's incredikernel are the best match (make sure you use the one labeled for sense, it's at the very bottom of his 1st post)
As another user pointed out, when you first flash a ROM / Kernel your phone doesn't quite know how big your battery is, so it'll take a few days for it to calculate properly.
The gingerbread releases I've found are a bit harder on the battery, as developers continue to develop better kernels and ROM's I'm sure that will change.
Also a few general tips:
- Don't use Task Killers
- Make sure you don't have apps that auto update frequently, and if you do and want them to keep doing it, know that this puts further battery drain.
- Download "spare parts" and check under battery stats for programs that use a lot of Data, CPU, and GPS.
- Don't overclock (if you're using chad's incredikernel then don't worry about anything regarding your CPU, his kernel takes care of all of it)

I've heard of spare parts from reading other forums. What exactly does that program do?
I do use advanced task killer. I'll uninstall it and see how it goes. And as for the updating frequency, I use facebook, have it set to update every three hours, as well as the weather widget. Other than that, I don't have a whole lot of apps, besides angry birds and a few things here and there that don't update.
And as far as kernels, I'm more nervous about flashing those more than ROM's. I'll check out Chad's though. Thanks for the advice!

You shouldn't be nervous about flashing kernels, all ROM's already have a Kernel included, so you do already flash them. As long as you make a nandroid backup via ClockWorkMod Recovery, then you should have no worries at all when experimenting with new setups.
Spare Parts is basically extended settings menu. The most useful features is it allows you to speed up basic and common transitions, and allows more in-depth view of programs using your battery and exactly what is using your battery (vibrating, 3G, Screen On, a certain app, CPU, etc)
It's free and it's not risky at all, so I suggest you give it a download.

Acesmod 007 -battery life and performance

Hey xda
I come from cyanogen7 and went for the acesmod rom because I was missing the nice widgets, looks, and overall performance of sense. I have now spend some time on acesmod and I must say that it looks very nice and I especially think that the sense keyboard works a lot better when writing danish.
My problem is now that I find acesmod drinking my battery like crazy. Besides this I find it to be lagging a lot and not that smooth a experience that one could expect.
Do anybody know what I could do about this. Have you guys experiences the same.
Alternatively I am open to other sense based roms.
Thanks xda people!

sense roms do use considerably more battery than cm7 roms, nothing you can really do about it apart from maybe calibrate your battery, theres a thread on here about how to do it

Again, calibration is not to be used to increase battery performance... Disable htc.com sync, use as less widgets and let them sync as rarely as possible. Disable pocket mode too, sign out of Latitude and make sure that your market and maps are not in the foreground when you turn your screen off as they won't release the wakelock then.

I can hear that there is not much I can do. Had every updating things disabled and also got the black wallpaper for power saving.
Are there then any sense based roms you would prefer over acesmod 007?

I have good battery life on 007 mod.... But I have used only sense roms, so I cannot compare it to others.

mine life battery is good, try using andrev_oc

andrev_oc? (This is only my second rom)

see here how to install
http://forum.xda-developers.com/showpost.php?p=16803896&postcount=355
hope it helps
edit: with ES File Explorer (in settings tick the root explorer and mount file system) copy the freqs to system/etc/andrev_oc

Interesting... I have tried a few Sense ROMs and was quite dissapointed by the performance, memory consumption and battery life, went to CyanogenMod 7.1 and now tried Acesmod007.
For me, it does everyhing as smooth as cyanogen, and something obviously very strange - the same or maybe even longer battery time. A full day with gmail sync, active gtalk usage, a little browsing, ~25min of calls, messaging... on 2G+3G and (mostly) WiFi. And the battery level is still not very low.
I'm very happy with this

The new 007 mod (v39) has even better battery life!
And the speed...

[Q] Best ROM/Apps For Daily Business Use

Hi All ,
I am starting a new job that's require a lot of dates,deadlines to follow,To Do List and of course mails and phone calls !
so what is the best ROM to do that job ? is it better to install MIUI as example to get the most free Ram and using apps for every thing i want to do ? Or Sense ROM is good enough in that and can get the job done ?
What's the best apps u recommend me to use whatever the ROM i am using ?
Thanks a lot and waiting your help

I do the same stuff at work but I also want my music and videos for the down time.
I have been using this for four months and it rocks...

1) For recieving calls you should be okay with any rom. Would be funny if a rom didn't have a phone app
2) For mails i suggest you try the app "K-9 Mail". I'm really happy with it's functionality. (But of course there are probably a lot of very similar apps out there)
3) For dates/deadlines i use the build-in calendar which syncs with the google calendar. Means you can access it from your phone, via a browser or a lot of desktop programms like thunderbird. As a frontend i use the "go calendar" widget, but i guess any calendar widget will do.
4) For To-Do lists i've got no idea.
5) Since you need the phone for business purposes, you should see to it that you get as much battery life as possible. You don't want your phone dying on you shortly after you recieved an important email and thus can't respond. Also for calls a dead phone isn't that great.
For that you should look into setting up your phone so it doesn't constantly drain your battery.
One bad thing about stock roms is the bloatware. I had real problems with google maps because it was constantly keeping my phone awake (and there are other apps like it). Now that i have cyanogenmod installed, my phone runs at least 10 hours more just because the bloatware is gone.
A rom like cyanogenmod can additionally bring you more standby time since you can set the cpu frequency 245MHz. I'm still able to make calls with that and everything like mails and calendar is still working. Only scrolling can drive you nuts (for instance if you are surfing with the browser...but you shouldn't be doing that anyway ). And you can always reset the frequency if you need more power.
Another great life extender are apps like juicedefender, that activate your mobile connection (and i think wifi too) only for a couple of minutes every 30 minutes or so (mobile connection meaning the data connection...it doesn't mess with the normal connection so you can still recieve and make calls).
Let's say you have a setup where your mobile connection gets activated every 30 minutes for 2 minutes. That's 4 instead of 60 minutes per hour and should save you a lot of energy. (And almost nobody needs to get emails instantaneously. Especially if you sit infront of your PC. Then you don't need your phone at all )
You don't NEED to make your phone go longer on one charge. You can always carry around a micro-usb cable and/or a wall charger if you really have to.
But i like it if i don't have to worry about my phone all day and only have to recharge it every other day.

I use Oxygen ROM ported for DHD. This ROM is awesome. Amazingly (or should I say extremely) fast, and the most amazing thing is the battery life. Normal usage (few phone calls, checking emails, etc) can last you for 1.5 days. The quadrant score is remarkable (even I got > 2000 with under clocked ROM in 768Mhz).
I installed Street Fighter IV (yes..it's warez one, but since everybody was talking about the choppiness of the sound, I gave it a try), and only this ROM gave me no choppy sound, especially if I OC it to 1.5GHz, even in 1GHz, the sound came from the game wasn't that really bad.

For work.. Sense 3.5 kicks A**S!!
...if your company uses exchange 2007/10(offsite/onsite)... a sense 3.5 ROM goes a long way!
Our company uses an in-house exchange 2010 server and it works like a dream with my DHD flashed with RCMix3D Runny 4.0 (stock with no themes... except maybe an UOT kitchen to change icons and transitions.. >_<)
Syncs very well your Outlook Exchange email, calendar, contacts and even tasks, and the widgets for the features are a godsend and looks cool enough to make even the iPhone4S zombies in the company green with envy!
I also have decent Remote Access through Pocketcloud using RDP/VNC since we also have Terminal Server. However, I'd still work remotely using my little netbook should i need to.... >_<
For my Music & Movies to keep me sane during home-work public transit, I use Poweramp and DicePlayer respectively.
And games like Shadowgun, Dungeon Hunter 2, Samurai 2 Vengance (and more tbh) are present and working very well on my phone despite its already intensive usage.
Hope this helps with your query... ^_^
