To ROM or not to ROM

Okay... I've rooted my phone, tweaked a few things (brightness, things that run in the background, etc), removed some bloat (including anything that is location aware) and have my beloved EVO running pretty much exactly as I want.
Here are my current battery use stats:
Cell standby 30%
Phone Idle 30%
CoPilot Live 21% (gps navigation app)
Android System 9%
Voice Calls 7%
Display 3%
1 day 8 hours 10 minutes 4 seconds since unplugged. I have 20% remaining.
No- I'm not kidding.
I've been told that the life I'm seeing is unusual, especially since I use the twitter feed and have a constant Exchange (OWA) push connection and get around 100 emails per day.
Having said all of that - and acknowledging that I'm apparently getting stellar battery life - should I take a chance with a new ROM (eg CM7)?
I'm afraid I'd be committing the proverbial breaking something that's not broken crime.
PS. I have no idea if this contributes to my battery life but I **never** plug it in - anywhere - until my phone is dead. As in shut-itself-off dead.

If you create a nandroid of everything, and then move to a different ROM and you want to go back, just restore the nandroid.
That will make it as if you never changed anything, essentially.

Given that type of battery life, do you think it'd be worth it for me, though? From what I understand, a big part of the reason many people flash is to get better battery life... How much better, though, can I really do? And I can't help but worry that all the extra eye candy may come at a cost (as in decreased battery life).

As far as better battery life, you're talking about changing kernels moreso than changing ROMs.
If I were you I would just stick to what you have, since you said it's running how you want it.
You can flash different font packs from here:
http://forum.xda-developers.com/showthread.php?t=801160
And different boot animations from here:
http://forum.xda-developers.com/showthread.php?t=708173
That way you can change it to how you want it to look, without messing with ROMs.
I would guess that your battery life is from discharging your battery properly, correct/controlled app background usage, and the way you use your device.

Thank you very much for the clear-cut answer... I think I'll do that - leave it alone.

Tips or What is in your opinion the best rom for battery life for the HD2?

I have searched around the forum but cant find any recent discussions on what is the best HD2 rom, i recently used CoreDroidGBX and i find the battery life to be pretty good on that (Lasts me till end of day with light use (Light use being screen on about 2-3 hours out of that day) End of day being 7:00 Unplugged Low bat around 5-6:00) But i see about 300-500 mA useage when im actually doing anything on my phone(But just like 2-3mA when its off and i disable data)
So i keep experimenting with different roms and i am wondering what you guys have experienced the best battery life with on your HD2's.
Also i have to manually toggle off data, is there a app to auto do it, like automatically whenever the screen is turned off? I had my phone on battery nearly 24hours (Although i was on my laptop and only used it for like 20 mins of phone calls and a few texts) but still a real full day was awesome

Coredroidgbx? There is a Coredroid series by Sergio and a hyperdroidgbx by Pongster. Both get rave reviews for battery. I run hyperdroid and I get 18 hours of normal use no problem. If you consider watching YouTube and flash video all day normal there is no rom that will last doing that.
Do you prefer a sense or a non sense build? GB or Froyo? CM7 or ASOP?

I would say u need to check some nand built on your own as different phone respond differently to rom built. hyperdroidgbx and rafroid hd 4 are good option to move ahead and check

+1 agree.
Thoese are my favorites too.
Sent from my Desire HD using XDA App

tried using CoreDroidGBX before also..
smooth... but battery is almost the same as other builds..

In my opinion the best battery life was in unofficial nightly CM7 by charsingh (1-3mA in standby). But due to some issues i had to switch to Typhoon CM, battery drain is notably higher (6-10mA standby) but for me it is the best ROM ever.
I think that the functionality of the ROM is litle bit more important than small diferences in battery drain.

Motoman234's Moto-MyTouch4G v3.3
Nand build and the best I've tried so far. I can get 2 days with light use (text and moderate calls) and a full day with fairly heavy use ie: web for 1-3 hrs and 1-2 hrs of various games along with calls and texting. I call my family on the east coast frequently and a 2 1/2 hour call is not unusual, loose maybe 20 to 25percent on the call depending on my signal. Great rom, a chef that responds and helps, again nand build. totally functional for me no issues flashed 4 different phones to it so far! .
I as a rule, leave wifi on always and use bluetooth, location, and background data only as needed. Blue tooth and background data will suck the juice right out! Still, if I forget and leave those on I can still get a full 10 hr day out of a single charge, provided i dont spend hrs surfing.

+1 for Cyanogen Mod 7. I tried a lot of DesHD builds but CM7 has the longest battery life by far for me. One charge lasts me about two days with light use. With all DesHD builds i never made it past 24 hours. Usually even less than that.
Furthermore CM7 is just beautiful, especially with cyanbreadX

i'm on rafdroid 4.0 and unplugged this morning at 8 am and the time now is 5:30 and i'm at 60% with moderate use and wifi off.
i will say though that if i play bubble blast 2 that thing sucks the battery like nothing and i'm not sure why. it's amost 1% battery per min i can feel the phone get hot from use.

Running cm7 unoficcial right now and seem to be getting good batter life, but I have seen it actually use 700mA (srsly) when just charging ..
But can idle forever. But lost 15% in an hour during lunch...

I just put HyperDroidGBXv7 on my phone a couple days ago and its been great on battery life so far. I unplugged my phone about a 12hrs ago and its at 74%, averaging about 3-4ma on standby. No classes today, so I've only used it lightly today for some quick wifi browsing, short gaming (Angry Birds), and about 30 texts.

Ok been trying cm7 and for some reason when actually using my phone I seem to get a steady 535mA battery useage, any suggestions on fixing this?

Anybody know why my actually using my phone usage is so darn high? I just flashed to the stock rom, reinstalled magldr + Clockwork and im about to flash android again.
Doubt that will help but i need battery life..

Help me out in HTC DHD

i am planning to buy HTC DHD in a day or two......
all my friends say the battery is poor and blah... blah..
but i like the design, features, etc...
is the Battery really very poor and is there any other trouble in that mobile!!

There are roms that could help you out. They can increase your DHD's battery life If you are willing to root your phone...

I most admit... With normal ROM, the battery really suck.
I haven't tried to root and put a custom ROM on yet, but only heard good things about it!

hey dude the battery usage depends on how u use ur phone
btw, i m also buying DHD on 17th very excited for my first Android

The battery is no worse than any other HTC, infact the battery is slightly better on my DHD than my classic desire.
Sent from my Desire HD using Tapatalk

I've got a standard DHD, not rooted and no custom roms and I have no problem with the battery. I can get more than 24 hours out of a single charge and that is with what I would consider heavy use.

Echoing what has already been said, yes the battery life can be quite poor. My phone will last for a "day" out of the house, by which i mean ~8am-6pm, but will be at ~20% when i get home, so will need charging.
That said, the rest of the features more than make up for that in my opinion

If you manage your data and what you actually use your phone for then you can get lots of time out of your dhd, if you slam your phone by downloading loads and streaming all kinds of videos to it and using gps on maps constantly then yea it'll go, but for the size of the battery and what the phone can do i'm amazed it lasts as long as it does.

Right now I'm at 11h and 39m with 56% left. This is with 3g on. Facebook and twitter every 30 min but its set to automatically update. Surfing, Texting, and a few calls were made as well.

Replace the stock ROM with one of the ROMs available here. I personally use LeeDroid 2.3.4 Beta 4 with an updated Radio. And I am very happy with it. It has given me a better battery life as well as removal of those useless HTC apps is a bonus. I still use sense which adds a lot of frills to stock android. Also look into the battery threads where there are ideas on what to do to optimize battery usage.

If you are getting your first smartphone you'll probably be disappointed in terms of battery. They are like little laptops and you know how much their batteries drain out. It's not that bad, but it's completly different than a normal phone.
You can drain the battery in 4 hours with very heavy usage, with semi-heavy it'll last for ~8 hours. With my use I get about 24 hours. I get up in the morning (15mins Wifi), go to school 15mins Angry Birds, 20 mins or more wifi, come home and wifi + play for 20 mins. Calls 5mins. Go to sleep phone on standby. Next day the same and after school I'll charge and it'll be at 5%. This is very light use.
I'm using Android Revolution, but I'm getting worse battery than with stock because I flashed a bad radio for Finland.
Other faults, I've only found one.
First: The speaker, it's pretty bad. Sometimes if you are in a noisy place you might even miss a call because of the silent speaker. Want to listen to music or watch youtube videos using the phone's speaker? That'll be hard...

I had the same problem with the ROM Cyanogen CM7.
Consumption of the battery far too high.
You should know that the HTC rom with sense use a proprietary driver and less greedy.
For other's rom's hacking in the kernel.
I returned on a rom with sense, Leedroid 2.3.4, I' have never eaten my battery so little.
For Rom's nosense, I wait that problems are solved

I'll second that. Mine is the same too.
Given the Pros of the device I will not mind the battery life. Its ok-ish.

I am on stock ROM and I kinda have better battery then when I was on Revolution HD. It gets better after a week usage and after a simple calibration. I get between 24 and 36 hours of medium usage and 3g and autosync aways on. I think its pretty great for this beast!

why is battery drain so different

hi
this is not question, just more a thought
now i have read on several post on different forum, about the battery drain on the galaxy s 2.
and my big "concern" is why is there sooooo big different on the battery drain. some people can last for 2-3 days and some only 5-8-10 hours. from what they are telling they are using the phone almost equally..
for an example this first post here, he still have 50 % left, although he saw video,playing , surfing and call http://forum.xda-developers.com/showthread.php?t=1055164
mine last for about 10-12 hour with moderate use.. and i have killed all unused apps/task/services, wifi ,only 3g, low brightness, wipe batt state.. and installed villainrom
it sounds to me that some people get a really good phone/battery and some not.

Everyone's idea of light, moderate and heavy use varies. It really only comes down to a few major things. How long the screen is on, how often the device is awake, and how intensively the device was operating while awake.

If people know what to do (search the bloody forums for a start)they can achieve good battery life, too many fools are too quick to come on here and complain about poor battery life without even searching the forum, also anyone who gets 2-3 days clearly isn't using the phone that much, i usually get a full day out of medium/heavy usage and you cant complain about that, this is a smartphone and if people are that obsessed with battery life i suggest they use an old Nokia

Very true. I can easily get 2-3 days if I just used it for calls and text.
Heck, I can get it to last 1-2 weeks. Just put it in flight mode and don't touch it except every couple of days to check %.
Why people don't just buy spare batteries is beyond me. I bought 3 spares + a wall charger off eBay for around $10. When I'm low I just pop the used one in the charger and replace with a full one. From 0% to 100% in 30 seconds. I even leave one in the car in case. Did the same thing with the S1.
BTW, to the OP why leave it on 3G? I'm assuming you switched off H. For me I use the 2g-3g widget and select GSM only. When I need 3g/H for data I turn it on.

My 2 cents
I will tell you this. For what its worth.
I've had 4 friends get the GS2. 2 of them are white, 2 are black (the phones, not them.)
In all four cases with the stock ROM They came and complained to me how they love the phone but the battery dies before they can get home.
All four cases I've done this update for them via ODIN
- ROM Update: XWKI4 (UK XEU, android 2.3.4 to support google video chat)
- Kernel: XWKJ3 (stock)
- Modem update: XXKG5
Each and everyone has told me they're getting literally exponentially better battery life, snappier response and stable usage.
Take it for what its worth. But i recommend your combo.
I think usage pattern is definitely important but i've experienced idle drain and gone through months of struggling with this. not all roms/kernels have the idle drain issue. The above combo should work well for you. Good luck

Well there are differences in software and usage, but thats it. use a clean up to date rom, good kernel and do not install crappy apps like facebook which drain the battery. Using a modem which suits your provider does make quiete a noticeable difference, especially with hspa activated, idle aswell as using the data connection. Battery life of 12 hours or less is clearly a use or apprelated problem.

Pathetic Battery Life on Vibrant Trigger

SGS Vibrant flashed with Trigger 3.2 the battery lasts for 1 day with wifi usage and even if kept for overnight it drains about 18-20% of battery should i move to a different ROM ?

You could
Sent from a cell tower to the XDA server to you.

Trigger has had one of the best all time battery life for me a everytime.
I think you need to
A) recalibrate
B) re-check to see if any apps are using battery life.
C) flash a rom if none of that works.

Here we go again for the millionth time.....

But for me trigger had the best battery life.
I'm not on the gingerbread roms and it takes me from 100% to 5% in 8 hours overnight even WITH Juicedefender (seems to be about the same without it also).
If anyone has tips on THAT, I would much appreciate it. I've tried calibrating the battery.

There is a setting that you can turn your radios of from x time to x time overnight. I have mine set for 11-6. If I am on after 11, then I take priority. If not then the setting does.
There is also a setting that will open data/radio every 15m/30m/45m/1h/2h or something like that to get updates for somethings (i.e. Beautiful Widgets). I have mine set at 2h. If I want my data/radio open I will do it myself, hence my long interval.
Been using this app for well over a year so I know how to tweak it a bunch. If you have JD+ see my battery guide and it will tell you more about its tweakiness.

Trust me. This guy knows how to use JD, check out his battery guide. It will be worth your time.

i wish i could get my phone to last a whole day without charging, i just dont complain because i know for a FACT that the reason my phone only lasts 10-12 hours is because of ME. im too stubborn and refuse to switch to battery-friendly usage. the biggest thing that impacts battery is the user/user apps. not rom, not kernel, the battery difference from rom-to-rom and kernl-to-kernel is barely noticeable (unless in the rare case where there is a bug, or developmental defect). if there was ACTUALLY a rom in exsistence that TRULY had superior battery life, then you wouldnt get 5-10 different answers in every single "what is best rom/kernel for battery" thread.
the problem is, people want to believe that they can save battery without changing their usage habits. this simply is not possible. no rom or kernel will realistically do this for you. if you remove 1 brick from a bag full of 15 bricks, the bag will be lighter, but still very heavy. you need to download "spare parts" or "process monitor" from the market and start analyzing the way your apps are acting. also look into data syncs that are happening in the background. apps that stay open behind your back/what they are doing, (an app called "autostarts" can prevent apps from self-running under certain scenarios). animation speed. polling for notifications. gps. wifi scans. overclocking. cpu/ram usage. proper sleep. widgets. brightness. 2g/3g. data usage. call time. text volume. - THESE are the things that really affect your battery life.
bottom line is, if you truly want to save battery you are going to have to get your hands dirty...there simply isnt a one-click (or one-flash) solution.

Hmm so i'm now on MIUI and it seems to be giving better battery life, also have been thinking of getting the extended battery for Vibrant is it worth ?

If it sucks so bad, grab one of these. I have it and it has given me at least a 20% increase in battery life. BTW, you must listen to the instruction for the Battery if you get it. 4 or 5 full Drains to 0% and then charge to 100% while device is powered off and re-calibrate after each of these full charge cycles.
