Yes... none of the 2.1 ROMs currently provide long battery life times. I believe that one of the chefs said it was because of the kernel and that it won't be fixed until HTC releases or leaks an official Hero kernel for Android 2.1.
However it also depends on what you think would be a good/adequate battery life.
Personally I charge every night so as long as the phone lasts circa 24 hours it is fine with me.
All 1.5 based roms should give you battery life over 24 hours even with everything turned on.
as for tips:
-turn of wifi when not using it
-turn of mobile internet when not using it
-turn of gps
-always put phone in sleep mode (end button) when not using it
- screen time out turned low
- backlight on low
- kill tasks that run in background
- don't have a bright wallpaper
Just depends how extreme you want to go
I have a decent battery life on the rom I am on (see sig) and I use a brightish wallpaper and auto backlight but always turn wifi off when out of the house.
Flashing a new radio file can also help battery life.
Edit: with a bit of use I have lost 5% in the last 8 hours on my phone today
Mhm too bad i like to use 2.1
Does 2.1 Roms drain the battery so much more?
Battery life is very important for me...
I am running the original Rom and i had to charge my hero every night, too.
But one day is okay...
Thank you for your tipps (bright wallpapers *lol*, but it make sense^^)
So what are you fav. 1.5 roms?

P.s. Does HTC want to upgrade the hero to 2.1 ??? Would be awesome...any dates?

indication is yes they are updating to 2.1 however they have not released any official confirmation of when.
rumors are March and/or April, but don't hold your breath
SenseHero 1.6 is awesome 1.5 ROM
Also it uses a nice theme, and can last for more than a day

Latest rumour says end of April
To me BeHero has the best battery life of the 2.1 roms and Villain had the worst (the life would literally go from 100% to 50% in 4hrs and I barely touched the phone).

See I am on Villain and have been on every version of it and never had battery life that bad, and VillainRom 3.4 is very good battery life.

I put on 3.4 yesterday and ya my battery life was terrible. The only thing is that I hadn't ever updated my radio. Now instead of it being dead within 4-5 hours I've gone over a dozen and my battery is down to 45%, which is pretty good for me. I'm a pretty data intensive with my phone.
if you want to test the battery life, test it 2 days or more!, because the first day every rom(almost..) is draining fast, because then it needs to set up everything etc(idk excactly why)

i agree...using 3.4...i feel the battery is not all that bad..(yes not as good as 1.5) but just about manageble..
if anyone has any more tips please let us know

Wow I find it very hard to believe that you only lost 5% battery in the last 8 hours with little use...do you have mobile data on or off?
Even with no use at all I can never get 5% decrease in 8 hours, regardless of whether its a 1.5 or 2.1 ROM. I keep my mobile data on all day and night and with no use at all i lose like 20% battery life in 4 hours.
If you want 2.1 firmware with good battery life, go foe BeHero_v1.3.2, I am using it without any trouble!

Trust me I was not lying I have no reason too.
Will report on what it does today.
Yesterday I had mobile internet mainly off but turned it off at certain times of the day.
So far today (3 hours since fully charged)
-wifi for about an hour
-use wifi things during that time (seesmic and News Rob mainly)
- bluetooth for 45 mins (journey to work)
- mobile internet for about 40 mins
- downloaded an app and tested it (used barcode scanner to scan a barcode (twice) and go to the download link)
- synced emails
- sent a text
- mobile internet now off and back asleep
And a reboot as my connection was lost for some strange reason
lost 2%

i can only say that perhaps ur battery is a special one..
i cant even get half of that with 1.5 rom (with the same usage)..i will surely lost like 10% with that kinda usage on phone..
no offense..but..unbelievable...
my current setting :
GPS , WIFI & Bluetooth off..
brightness around 15%
dark wallpaper..
mobile internet on when browsing needed
@aziz831
Lennyuk´s battery consumption is real. My battery would last 216 hours just in idle. But that would mean just asleep and waiting for a call.
I use WiFi 18/7, I have in that time mobile data enabled, I have a brown wallpaper and my backlight is on lowest level (but I can still see everything). My average loss is 1-1,5 % a hour if I´m in idle with all this enabled. Over night I do disable WiFi and auto sync, that saves a lot of power.
My average time of usage with one load is about 80-96 hours.
Dear
My Vibrant (using Fusion 1.2) losts about 25% battery life each night (7 hours not use at all). Most battery goes for cell standby. Is it normal or not.
And what is cell standby?
Thanks.

I use obsidian 4.2 with a stock kernel and I loose about 1-2% per hour overnight. you might want to flash a newer rom or ODIN to stock and then reflash the rom you have. Hope this helps.
EDIT: also have you reconditioned your battery yet?
that also happens to me when using fusion roms. yeah it's a really good rom but it sucks the battery life when in sleep mode. try uaing other roms.

Yesterday, I found SuperPower (http://forum.xda-developers.com/showthread.php?t=807989) app which auto optimizes the phone to save battery.
It is really help, the battery just lost ~ 15% last night.
Not bad, so I will stick to Fusion 1.2 & SuperPower some days.
Thank you.
this is the only reason i hate CM7. it drains battery like hell. yes, im already using "conservative" cpu governor and have JuiceDefender installed.
when i was on the stock LG rom, battery life used to be about 3-3.5 days on normal usage. after flashing with CM7 (the latest stable version), i need to charge it every night. if i do a lot of net surfing, battery will last for only 15 hrs.
is there some other gingerbread rom with which i can get back the normal battery life?
ive never tried this rom but ive read that rjtchn's cm7 has good battery life. the last time i checked his rom isnt on xda but u can google his rom

First, you can go back to Froyo by flashing the stock ROM through KDZ. But all your data would be wiped out. Take backups.
And regarding battery backup, I think 25 hours of battery backup on moderate-heavy usage is fine. I'm not sure whether we can get 3 days on froyo with the same usage. I didnt use froyo much as I immediately rooted my phone and flashed CM7 based ROMs.
On Andy's ROM with Andy's kernel, I can get 25 to 30 hours with heavy usage, with 6 hours of sleeping period in between. So it is 20-24 hrs of almost constant heavy usage.
void. #forever
I'm using void. #forever with Franco's v18 BFS kernel.
I had 2 days & 20 hours with moderate calls, SMS & browsing. I think I could have reached 3 days until an exercise app surprisingly kept my phone awake & drained the remaining battery.
Using GB 2.3.3 - at the moment for testing purposes GingerCriccoROM 1.2 and latest Franco GB kernel. 3G data always on, sync on, (fb, twitter, gmail, email etc. autom. check every 30min.) Calls, sms, browsing, pretty heavy use and i got after first full charge and battery stats wipe 1d 14h - still 6% left. OC 480/729 smoothass. Still testing - at the moment i have 30% battery left after 1d and 7h.
i run void #forever and franco kernel
it usually last about 2 days on average (48+hr), i dont use the phone functions that much, mostly just browsing the news and sometimes GPS when i get lost out there, but i keep wifi/background/sync always on since i rely on gmail/gtalk/gvoice heavily
horrible battery life
flashed rjtchn's cm7 just now. And havent even restored backups yet. And as I surf on xda now on my wifi, battery is decreasing by 1% every 2 mins in front of my eyes.... it was 100% at 5.35pm and its 89 at 6.04pm now..... WTH is happening? Also to mention, I had bought my phone only a month ago with incredible battery till I started flashing Roms...
I'm using. Rover theme. Does that have. Anything to do with battery?
I had wiped battery Stat when my phone was in 100%, then I flashed the rom, rebooted, and then connected to USB mass storage for 20 mins to do transfers. ( it got charged again). Anything wrong in this process?

I am wrestling with battery life. Not being able to run 24hrs on one charge seems silly to me.
To use some round numbers, from best to worst given my standard usage patterns: {0}
48 hrs (2% per hr drain) -- stock LG 2.2 ROM rooted, crapware removed, SetCPU onDemand 122-600. Consistently runs 48hrs on a full charge.
24 hrs (4% per hr drain) -- stock ROM as it came out of the box.
18 hrs (5-6% per hr) -- CM7 RC1 unchanged. It seems closer to 5% per hour when I set onDemand in CM perf settings to 122-600 and tore out the launcher (using the delightful Zeam instead)
I can go to sleep with my OptT on the bedstand and wake up 8 hrs later and it's dropped from 100% to 60%.
I did do a brief test of Void forever and like the cleanliness of it. But development appears to be ended so no hope of BT working well or battery optimization. If I had an extra T500/509 I'd send it to the dev so he could continue testing. I did run it for a few hours but after I tested BT I didn't have the heart to go install all my crap on it for extensive testing. {EDIT: going to try it out today and see if I can hit 48hrs with it}
I am a big CM fanboi so I would love to hang in there with Mik until BT and battery are better. I mentioned battery drain in a (pre-CM7RC1) thread once and it was not well received, so I haven't mentioned it again until this thread.
If BT and battery don't eventually get improved (and I assume they will) I'll stick with the stock, rooted ROM.

i checked. the only "app" having max. usage is android system . and it is a fresh flash. i had formatted the sd card also. and i dont use mobile data or gps, i use only wifi. and im not on a 3g network (because my operator hasnt even launched 3g ).
now the time here is 9:22pm and batt. is 63%. the only thing i did was surfing and mail checking on wifi.

i second u.... rooted stock rom is the best rom, only if there was a way to get CM settings menu in it
i played angry birds rio for 30-40 mins and its 11:40pm here with 34% batt. ugh. will try void rom
I'm on gingerlol with paolos kernel. I use my phone for a few messages a day and about 1 call per day. Playing around with the phone depends, somedays more somedays less. Battery lasts 2 to 3 days. Can't remember having more juice on stock froyo.

Same here! Just remember to change the governer to sth like on-demand or conservative!
Well... reading you guys talking about 2-3 days of battery life makes me think that I'm either doing something wrong, or my battery is a bit damaged, 'cause the only way I could think my Optimus One would last for 2-3 days would be with no use at all.
I got this phone from a friend who had owned for only 2 months and the phone was already rooted and with a custom ROM already installed (Light 2.2.2 which is fairly close to stock). With that ROM the battery would last for a day max.
Shortly after I started installing other custom ROMs and testing them:
- Devoid Froyo Final: The most responsive ROM I've tried, but I had horrible battery life with it, with only around 18 hours of bat with moderate use and 3G on.
- OpenOptimus: Seems a bit laggy to me, and battery life was not even better than Devoid's
- LOL 1.4.2: I finally settled with this one. The ROM is pretty responsive (although not as snappy as Devoid) and at least with this one I can have a full day of battery life (sometimes a bit more).
I must say that I always keep an eye on apps running in the background and stop those I know I don't need always running. I also use Titanium Backup to "Freeze" apps that I know I won't use on a daily basis (like Google Maps and Navitel GPS).
The other thing I'd like to mention is that I keep GPS off (unless I specifically need it), but I always have data ON, either via Wifi when I'm at home, or 3G when I'm out of home. My Wifi Sleep Setting is set to "Never".
The only two apps that I know are working regularly on my phone are:
K9 Mail: Receiving mails for 5 Gmail accounts (all configured as PUSH so that shouldn't drain much battery)
Whatsapp: Receiving messages from friends and family, but that app is also PUSH so battery drain should be minimal also.
Overnight drain with Wifi On is about 5%
What do you guys think?
BTW... probably during this week I'll flash one of the 2.3.3 based ROMS (GingerLOL). I hope that being a "LOL" Rom it would be as stable as my current one.
Not a long test, but I did put all my apps back onto void #forever for an apples to apples test.
Set it on my nightstand and we both slept for 6 hrs. 100% down to 66% in 6hrs, for a drain rate of 5.7% per hour. Gack.
I suspect the real killer is the broken CM7 bluetooth stack in our devices at the moment, but since I use my phone gets used as a wireless mp3 player most of the time I really need it. When CM7 for OptT gets a fix for BT I think It will be nearly perfect for my needs.

my battery life isnt that good either. but then again more performance=less battery life
Void #forever is truly the best rom I have ever tried.... The best thing on it is that its "void" and u can choose which stock aps to install. Thnx a lot guys for recommending me this rom.
Rjtchn's rom had better performance. Quadrant score was 1005 without overclocking(i don't remember the exact). Void's score is 840. But it has incredible battery.
Its the first rom I have ever seen with cell standby having the max bat. usage on 2g network. (all others had android system). That means just by putting on flight mode, things would go even better

It's a balance issue, I guess.
I was researching another issue and so set my phone (as described below) down for 20hrs 23mins and it is now at 84% battery. 23.3hrs / 16% battery usage = ~0.75% per hour.
Compare that with 5-6% an hour I was getting with CM7 on the bedstand. I suggest that CM7RC1 is , despite it's general wonderfulness, not providing 6x the performance for 6x the battery drain.
I am a CM faboi and have done the "buy Cyanogen a beer" thing on his site. I eagerly await CM7 going gold for our devices, and I hope the battery/performance balance is on parity.
Hi guys,
I'm just interested in knowing if my battery life is normal. I read on GSM-Arena that X10 should have 400+ stand-by time, but according to my battery consumption overnight (no wifi, no data), my battery can only standby for around 100 hours on 2G.
Here's a screenshot of the battery usage throughout today. I practically didn't use my phone for the first half of the day.
Does this look normal for my WB V3.6 ROM? Please share your experience with me and let me know your version of ROM.
My battery life was miserable when I was using WB v006. I had to recharge my phone about twice a day on normal usage. I don't have a screenshot for that. Right now I can listen to MP3 for 10 hours no problem on WB V3.6.
Since yesterday evening I'm on WB's 3.7 (features). Since end of July I'm on WB's GB ROM and my battery life is quite well.
During night in flight mode and without wifi I loose nearly nothing (8 hours). Yesterday I used the phone the whole day quite often and within 24 hours the battery went from 100% to 20%.
Charging once a day is ok for me now. Before, on Trip's MIUI FROYO, it was even better. 30 hours without charge was normal.
if u want more battery life jus turn off the bravia engine and it will give even more backup !!! i did this yesterday and i normally use around 60% brightness with 3g network and listen to music jus for half and hour ..so used for around 17 hrs or so but still with 65 % left ... i jus turned off the bravia engine so its giving even more battery !!
Hope it works for you too !!
Thank me if it helped u !!
I will try that. Thanks! I don't really need BRAVIA anyways.

My battery drains 5% or less during overnight (1am-8am). I'm using an Xperia X10i on CM7-ZMOD CYANOGENMOD 7.
I don't know if I should but I haven't used Juicedefender Ultimate since using this mod. My Android is 2.3.5 on this mod.
Hi everyone,
I've been running MiniCM 2.1.5 (nAa -06)for a few months now and it runs pretty fine and it's very nice to have Gingerbread and so on.
But I'm very disappointed with battery life and I don't see why it is so bad.
I understand the MiniCM should have similar if not better battery life than stock (2.1) firmware but I don't see how this can be achieved.
I always used to have 2G/3G enabled, and with stock ROM my battery would last up to 5 days with minimal usage. With MiniCM I don't get over 2 days. With normal (low) usage, my battery now lasts about 30 hours.
When the battery is empty after a minimal usage cycle, I have something like 49% cell standby, 45% phone idle and a few % display, which basically means I'm not doing anything with the phone and there's no app running in the background etc.
Switching to 2G only (and other famous battery saving tips) will give me some extra hours, but still nowhere near stock battery life (with 3G/2G all the time).
I have no tasks running that should drain battery,
I have also wiped battery stats (using the BatteryCalibration app) with no noticable effect. My voltages are displayed between 4.15(100%) and 3.65(0%) . Shouldn't it drain down to 3.2?
What are your mini battery lives?
What are your voltages at 100% / 0% battery?
How to make MiniCM last as long as stock ROM?
I never get any more than 14 hours on Flame.GDX, also on MiniCM7pro I got roughly 12 hours.
I dont think theres alot you can do. JuiceDefender an apps like it may be able to help you find an hour or two longer

I have returned to stock 2.1 after a lot of experimenting.
I have tried:
- MiniCM7 2.1.5-7 with nAa
- GingerDX with nAa
- MiniCM6 1.0.2 with stock kernel
I have found that all of them use a lot of battery, though i can not see why.
They will all result in ~<50h standby, while stock 2.1 can reach ~100h.
I wonder if this is some SE secret, or if one can achieve this with custom rom, too.
