Hi All,
When i look into (almost) all roms i see the problem with the battery drain problem.
To bad i do not have the knowledge to find out what to do.
But i think that some smart developers work together to find a solution about this battery drain problem.
So that's why i start this thread so we can discuss this

It would be great if he could share the knowledge
I am using LeeDroid 1.4c and I too experience battery drain issues...
Someone tried this one http://forum.xda-developers.com/showpost.php?p=7170484&postcount=173 ?
There's a really good battery life on the OD 2.3 ROM Love it!

Thanks, but i don't like the interface.. want have the sense feeling
Drain
Tested a lot of roms with froyo and sense. The roms based on 2.06 base are draining relative more then the roms based on 2.04.
Above is not scientificly tested.
Charge to 100% , go to recovery , advanced , wipe battery stats. Enjoy greater baterry life

I had NONE battery drain problems on any of ROMS 2.1 or 2.2, and i did try alot of them.
Maybe theres something wrong with your phone itself (battery).
But definetly try wipe battery stats in recovery.
Since 08:00 morning had WiFi on.. network Data of... and now 12:02 battery is now 90%. DId have play with config the Tasker Tool (Great app).
Tomorrow i will do the test again but then with Network Data on and WiFi off.

Yup, that ROM has the best battery life by far...

people are having mixed results on the battery perfermance of adam's sensefroyo rom. i experienced a poorer battery life compared to eclair (i used Amer_v4 and the battery was excellent) but can still manage to last a full day usually. haven't tried out the froyo roms though.

btw aren't you're using opendesire?
I've changed about 8 roms, mostly used 4, but can't say there was a huge difference between them. 2 days of normal use, 1 day of heavy use.
Possibly shadowfrost and DeFrost 2.4 had the best battery life and I had the fastest kernel installed...
I would think that - some isolated problem aside - mostly it has to do with some applications/settings

sometimes my E-Mail application is consuming most of the cpu. It keeps the cpu at max frequency. Even if i try to end the taks with the app "system panel" it wont solve the problem. I have to go into the app and make a manual sync.
i also found out that automatic brightness is using loads of battery. since i set it to static I'm experiencing almost 2 days of battery life with moderate use.
I'm on Defrost 2.1
Hello again everybody,
Yesterday whole day online by WiFi. Using phone couple of hours and my Maildroid Email was active without prevent sleep mode.
Battery was empty after almost 17hours. (+/- 5% every hour)
Today. Wifi on. Maildroid now with prevent sleep mode ON.
Have unplugged the phone 4 hours ago and battery is at 75%
Tomorrow i will test this with Network Data on.. and without prevent sleep mode of Maildroid. And day after with prevent sleep mode.
I know for sure.. the battery will drain very vast for both situations...
BUT Ill let you know
EDIT 26-07-2010: Battery was empty tonight on 1:30.
NOW I do the whole test again but now with network data on and WiFi off
Ive had the opportunity to own a Nexus One at launch and a HTC Desire...I always found Android OS to be the issue whenever i had excessive battery drain.
Ive found my issue to center around the OS 'calling home to sync' (whether 'sync' option is selected or not)Initially, the problem was resolved by deleting all my sync funtions...but that was obviously not practical........ so now I keep my GSM data connection running and I get about 2.5 days on Open Desire (non HTC Sense).
AdamG seems like the guy who knows what hes talking about - His changelogs for OpenDesire actually hint at him having done some battery drain tweaking...whatever he did, he has definitely fixed it
Cheers

I've tried so many ROMS in the past few weeks to try to solve battery drain issues. On some, I could almost see the percentage dropping as I looked at the home screen! I even bought a new battery thinking I might have killed the original.
OpenDesire does seem to be the way forward re this problem if you're intent on the HAVS kernel. OD2.3a gave me almost two days of varied use.
However, and I know this is going backwards, an earlier DeFrost - the 2.1, is brilliant for me. I'm now at two days since unplug and still at an unbelievable 45% - yes, I know, I thought it was broke as well! For now, I'm sticking with this one. Everything I want works and I don't have to carry a spare battery in my pocket when I go out.
Hope this is of some help. Don't despair. You will find the one for you.
Cheers
I don't get why everyone says they have such a issue with battery.
I get about 2.5-4 days of use with DeFrost 2.2 and have done about so since DeFrost 0.9. I've had it up around five days once.
How are you actually using your phones?
It's not a "Froyo" issue.

It's very interesting to me how are YOU using your phone?
Come on, 4 days ? When i talk about 30m to 1h each day and using a phone little bit, i have at least 30-40% down.
u mean u only drain about 25% each day? are u actually using your phone ? wifi, calls, 3g ? or u have a expensive pocket toy just to show to your friends ?
Guys,
I've been jumping between ROMs since rooting my phone last week and one thing I've noticed is that my battery life takes a big hit when I'm using the G2 ROM.
You'd think that since it's a lot closer to stock Froyo than the Bell Desire Z ROM it would have better battery life, but that not what I'm seeing.
With both ROMs it seems that they will stay at 100% for a two or three hours and then start coming down - however it's much more dramatic with the G2 ROM and it seems as though it's battery drain gets accelerated.
Has anyone else noticed this?

For my part, while using CM 6.1RC1 the battery drain was amazingly bad.
Under Modaco G2 ROM, it's more reasonable. For casual use for 7h since being unplugged, I'm at 76%.

My phone's been unplugged for almost 7hrs and I'm at 85% battery on my original Bell ROM.
If you have Spare Parts installed, check Battery History. From there click on the "Running" bar. This will tell you how much time the phone has spent "awake" (this excludes the time the display has been on or while on a call).
I'm at 2hrs 18mins (+20mins with the display on).
Give my stock g2 rom a chance and tell me how that compares. I get better bat life out of stock kernel myself. Bet we could use some uv.
I've noticed something new.
I had my SIM card out of my phone today and it's been unplugged for 5hrs with not cellular network (but everything else going via WiFi) and it's still at 99% battery life.
Uptime is 5hrs 53mins with Awake Time at 1hr 36mins.
Is the cellular connection using more battery than it should be?
it looks like a combination of issues.
1. the android system uses a lot of battery
2.cell standby uses a lot of battery but less than android system
i have a unlocked bell desire z.
installed CyanogenMod RC2 but had to roll back to a sense based rom because the battery drain was just too much.
I figured it out, Kik Messenger was the main culprit.
It's been great since I uninstalled that.
To figure it out o had to restore to a clean rom and install one app at a time. At that point id leave my phone alone for a couple hours and check "wake" time under battery history in Spare Parts. If it was more than 10% we had our app.

seems to me the mocado in my g2 gets better life than the stock g2.
id give up a lot of features for good bat life.
are there any roms created for bat life?

ei did you unlock your phone already?
I rooted and flashed cyanogen 7 RC2 onto my phone today, keeping the stock kernel. Everything is great except it seems to take longer to charge. This is using a wall charger. Anyone else having this issue with this ROM?
I am also having this issue. It takes a while to charge.

Changing kernels will give you faster charging - I'm favoring invisiblek's latest right now. Another which gives fast charging is Chad0989's.

This worked awesome. I flashed the first kernel you mentioned and my phone was at 40%. 10 minutes later i looked and it is at 56%. Im not complaining at all, but is that charging too fast? What i mean is it going to cause any damage to the battery charging that fast? Just curious. I mean thats faster than when my phone was stock.

Heh, no idea if it's hurting our batteries ...
Lol, I understand. I will just find out sooner or later. Who cares, right now its perfect. I love this build and kernel combo. Any suggestions on setcpu settings?
The stock kernel does well but I've had the best luck with incredikernel every time. Charges the fastest and battery lasts the longest.

Which .37 kernel gives the best battery life? I flashed Incredikernel last night and then charged the phone. This morning I used it for 10 minutes to check emails and the battery went from full to 79.
Oh, and I'm running CM7 RC2
Sent from my ADR6300 using XDA App
I'm also very interested in this. I just recently rooted/flashed CM7 RC2, and the battery life has been quite disappointing so far. Even with the unnecessary services turned off, my battery drains quite quickly.
I am rolling with SkyRaider 3.5, Lou's #8, an 1800mah battery and this morning, I shocked myself!
I left my house w/88% charged. Took my son to the dentist - used the phone for probably 44 minutes during that, just goofing off, reading, tweaking and whatevering ...
When I left the dentist office, 77%. Drove to work (1 hour) ... sitting at 74%.
I am also running the evo radio - which some say helps or doesn't - but I'm as happy as can be.
I turned off all of the memory management stuff and the phone is lasting longer...
I should also add - that I use Juice Defender, however when USING your phone, it is "defenseless". I find it to help me a lot with my "in my pocket" battery life. You still get txt and calls, you just don't get internet traffic.
YMMV
Where did you turn off the memory management features?
I've been using ziggys latest on Incredibly Re-Engineered Z and having great battery life. 14 hrs today off charger and was still at 50%.

Hey guys let me tell you about this probably normal but weird thing that happens to my inc, it gets really hot from the back. I have been using the web (couple pages), mms app, 1 phone call, and the xda app. Have also installed advanced task killer froyo and stopped all applications from running on backround. I am using skyraiders 3.5 rom. I have it plugged in to the wall charger. And after I unplug It just dies quckly, its temperature is 109.8°F/43.2°C. Im using stock battery. Can the battery be causing this? Am I going to have to replce for another battery? Does anybody else have this problem? Any feedback is appreciated.

I've had mine to 115°F. There's tons of debates about task killers. That in fact could very well be causing your problems. If you have it set to kill background apps that are meant to run they will start up as soon as the task is killed. This cycle will drain a battery pretty damn quick and cause it to get hot. My opinion, take it off. Its not needed. Just cause its "running" in the background doesnt mean its actively doing anything. look at the battery use and then click on an app thats "running" it will tell you how long it has been actively using power.
Task killers are bad.
Your temp is fine, but watch out if it starts getting around 115+. The LED will flash if you hit 119, that's getting into the danger zone.

Also get app Android System Info (by ElectricSheep). You can go to the task tab, then sort by cpu to see what app is running most. (Android System info, I.e. the app you're using, will be quit high. But that's temporary). Like others said, it's probably the task killer.

yeah i thought so! well the rthing is that i had another inc before the one i had and it wouldnt even get near this hot but im looking on ebay right now to buy another battery, and just test it out to see if the battery makes any difference!
another question, do you think the OEM evo battery will last longer on my inc? i mean since the evo runs more apps and the os is more complex? would it fit my inc?

The evo is just a bigger screen version of the DInc with WiMax.
I meant to say since the evo has a bigger screen, and its 4g , so i think it uses more battery power than the incredible right? So the evo stock battery should holdbmore power than the incredible stock battery

Yes, the evo's battery is a little bigger but I really doubt the battery is your problem. If I were you I'd just do a clean install and see how things go. Don't download a task killer either.

The only task killer I can recommend is watchdog. It doesn't act like other task killers. It doesn't kill anything by default. and warns you if a background task is using over a configurable percentage of cpu time. you can then kill it if you desire. Pretty useful for those rogue apps that some times freeze up, and take the processing power with it.

+1 for Watchdog, wouldn't call it a task killer tho as its more a cpu monitor but it can kill tasks also (because of its high usage)
+2 for watchdog. Use the paid version and love it!
