[Q] whats the best battery effective kernel? - Optimus One, P500, V General

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

thnx, ill try it and post updates.
btw looking at http://forum.xda-developers.com/showthread.php?t=1137142&page=4 , one says he got 25 hrs of battery.... are CM roms so battery hungry? i really used to get 3 days of battery using the stock LG rom....... but its froyo and i cant go back to froyo....

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.

[Q] How much battery life do you get with Obsidian v2?

Honestly the battery life on this is not good for me, with no use but about one call I get 10-11 hours tops. With constant use(essentially not stopping for sleep mode)browsing and just going to apps like xda and the market I get about 4, back on stock 2.1 before the JI6 update I could go days on standby. I've wiped battery stats plenty of times now and seem to get no noticeable change. Also I've noticed that my battery will charge fully in 2 hours.

The best two firmwares for me so far have been Bionix Final (JI6 based w/JI2 modem) and Obsidian v2. Following my usual daily routine I'm getting about 14-16 hours from Obsidian v2, which includes a smattering of phone calls and texting, about a half hour of solid app usage (ye olde lunch break at work) and frequent checking of the display for time (I'm a manager with a fairly large staff so staying on top of what time it is, is a critical thing for me). At work I live in a very marginal data connection zone, with the phone frequently switching back and forth from 3G to Edge as well, and this hasn't had quite the negative impact on battery life that JI6's baseband usually implied.
I did get slightly better battery life with Bionix Final, but not enough better to justify going back. It seems my experience are quite the opposite of yours, or at least very different. With this being the case, I'd just suggest you use an app with more granular monitoring capabilities (like for instance Spare Parts) to try to find out why your battery life is so poor. I would wager it's probably app related and not OS related. Best of luck regardless.
If i used the phone like a computer i would get like 4-6 hours of usage (that's non stop usage) but if i used it lightly i can get like 15-17 hours. I guess it's not possible for me to use the phone with heavy usage for more than 6 or 7 hours.

[Q] Whats the best ROM for battery life?

Just wondering because right now I'm using GSB v2.6 and I'm getting max 6 hours of battery life through normal use like checking email, sms, casual browsing, and listening to music.

Have you tried re-calibrating your battery? Made a huge difference for me; it's good to do especially with a lot of ROM flashing, but even with just one it can throw your battery calculations off.
FYI follow the instructions to the letter, otherwise you might as well not do it at all IMHO.
I had the same issue using GSB 2.X. Switched to OMGB 1.1.1 and i now get 15 hours with moderate usage and no tweaks.

I've gotten over 30 hours before with GSB, immediately after a recalibration.
Your best bet for battery life is setcpu settings. As long as you're using froyo and gingerbread you'll get a boost.
I suggest Tazz as his ROM's have always worked for me. My setcpu sleep profile is:
min 19mhz
max: 480mhz
governer: smartass
and in advanced settings I have:
polling interval: default
Whatever the next one is: 98
Ignore smart or hwatever the third one is: 1
bias: 4
edit: With this I can get a good day or two of moderate use.
I found on GSB that that 19mhz is too low and the phone does not always wake from sleep. I followed workshed's suggestion of min 480 mhz with max 710 using CM7's CPU settings and all worked very well...that is until 2.0 when battery life went to hell. I recalibrated but i think the problem was my exchange mail app.
Oh, and with smartass you shouldn't have to set sleep profiles. Supposedly it's "smart" enough to figure that out
You can also try collins battery tweak, I use it on tazz gingerbread and it works awesome my phone used to die pretty fast before I tried it and now that I put it back on my phone I am very glad I did.
Im running GSB 2.8 but for me, all seems to be going well.
In one day, off a single charge, I've gone 12-14 hours at a time!
Make sure you always charge correctly, and don't abuse the phone's battery all the time!
Been trying out various ROMs and lately, I've settled on FroShedYo's Final V11 with CM6.1 as my everyday workhorse, stability over speed, and with a bit of battery calibration - getting an average of easily 20 to 30 hours off a full charge on OEM 1500 maH battery originally for the HTC Ozone (so it's about 15% higher capacity than stock's 1300 maH, which I keep as a spare/backup.)
With a bit of tweaking on CPU clocking (Ondemand), turning off vibrate & alert sounds/LED's, and email checks every 60 minutes (1 account only + Gmail pushed) and minimal widgets open, etc. - I can leave the house at the beginning of a long day, go about daily business, voice calls, check email checks, quick news & weather update, etc. and still have 25% to 50% battery life after an extended 12 to 15 hours day on the move, depending on how the device is used. I get a poor 3G signal at the house flipping to 1X often & back, and wifi OFF on the road (BlueTooth ON for driving but no Maps/NAV (ON at home.) In short, plenty of variables on how the battery is getting drained - in standby mode, clock speed is lowered so I could still be over 90 to 95% battery after 2 years but it will slide downward with active usage. After wiping/flashing & reinstalling all the APPS & fine-tuning the settings, I do a NAND backup and then do the battery calibration - and after 1 full cycle, I've been consistently getting these standby & usage time - which I can live with (C2C flashed and extra goodies on a 16GB SD card.) Yesterday, it was showing over 50% after 15 hours of light/moderate usage.
I've tried the latest nearly finalized GSB/GB Roms & variants, they are faster & fancier, but FC's, GPS issues & other minor bugs plus "not as good" battery life had pushed it back to 2.2 OS on the Eris. OMGB 1.1.1.1 and the Condemned CM7 just out this week are pretty cool - but battery life really slide quickly - unlikely to see more than 10 to 15 hours of usage out of a standard/non-extended battery.
The other one that I like is the Nonsensikal 2.2.1 ROM, troublefree, stable & reliable - the edge on battery yielding to FroShedYo's version ( keep that on another 8GB card along with the newest GB releases for "playing")
Otherwise, the xtrSENSES 5.x and xtrROM 5.x are fine as well for everyday use - performance & battery life-wise over the latest stock 2.1 ROM.
Those are my two cents for what it's worth, great work being done here and it's giving new life to the Eris, not quite EOL for some of us - played with the TB in the store, nice big screen & fast, but I'm not about to wear a "brick" phone going out on the job with an extended/bulky battery just for bragging about 4G/LTE. Mobile devices have come a long way, I still got my original analog MicroTac XLT with a 2200 maH tipping the scale at 10 oz in my bottom storage drawer.
On the sideline for a "polished" GB/GSB ROM with the bugs resolved and better battery life, and I'm off to flashing it on my spare SD to test it out. for the "adoption" usage.

A day and a half as in 36 hours? Only 20%!? What is your usage pattern?
I have a friend with RLS5 in a Blade with 60h of battery life... with 23% left battery to use.
I think..LOL 1.4.2 and OpenOptimus are the most durable rom..(sorry for my english)
In this moment devoid.franco.
Or maybe anyone but CyanogenMod 7, that drain my batt 20% in the night
It doesn't really matter as long as you know how to configure it to save as much juice as it can. SetCPU profiles does the most for me. Running slightly modified stock.
i use CM7..for me this rom is good for the battery life..but for anyone is different..I spend about 2 days with one carge..so you can try and decide

That would depend on you ... But I cannot stress this enough ... before writing off a ROM, be sure your battery is calibrated ... that makes a big diff
I was using my own ROM and used to get about 35~40 hours ... 2g always enabled ... fb, twitter, corporate mail, gmail always sync ... chat a lot ... dont play too many games ...
Nw on CM7 by mik_os and get about 30 hours with similar use ... I stick to this as its gingerbread + CM settings ... plus pretty much bug free ... only drawback is divX doesn't work
Definitely not CM7. It's not terrible bad, but compared to the ROM I used before, Void, it was worst. I don't have a huge problem with battery life except for that one night I lost 20% over night standby. The one other ROM I tried was Void and I thought that ROM was overall very good combined with good battery life, but I switched to CM7 just because I liked gingerbread. Compared to other phones CM7 battery life is normal.

Yes it does. I use a stock 2.2.1 and it lasts about 48 hours before going below 25%.
I use it moderately. About 1 hour calling/day. 2-3 hours Wifi/day. Data always on 2G. 3G causes it to last about half the time. Games for about 1 hour/day.
devoid.franco consume 1% of the batt between 10pm and 7am (with all off, overclock 428-729 smartass).
CM7 consume 20% the same hours (all off, 245-600).
Im presently running on Stock rom with devoid.franco kernel v11..Getting great backup. 2 days with some calls, lots of sms, occasional browsing on edge and lots of music. Pretty happy with that.
Nessy is the one that i prefer does much better than the stock rom ever did. i can now use programs like pandora in the car and actually use the phone later

whats your battery life??

post your average battery life...i want some tips from the ones who have best battery lifes..
to get the best juice out of ur o1..
use devoif froyo-final..
i got about 3 and a half battery..
3 and a half days ?? are you kidding??
My battery only lasts maybe up to 12 hours... if I'm lucky
Tried removing widgets, using a batter saver... tried charging the battery, deleting the battery stats file, discharging it recharging it... shortened display on time, turned down volumes
I don't know what's up? I've tried wiping and reinstalling ROM's... I don't even use it as much as I'd like because of the battery life
Optimus V (VM670)
AOSPmod 20110601
16gb sdcard w/1gb ext4 partition
Don't use battery savers, they increase it drain...
Mine on devoid froyo only lasts one day..tried wiping battery stats many times..but same result..
Mine is on devoid.final with franco.kernel v16.1, and I get about one and a half day of battery on average use. I play at times, send quite a number of texts and make a call once or twice a day. I developed the habit of bringing my USB cable to charge my phone at work now. :/
my phone doesnt last even for about 18 hours if i am using it on average basis by which i mean 1 hour gaming...2 hours of time pass by simply changing settings and all...but i do text quite often and have around 100 apps installed on my phone...will it help if i keep only which are necessary and use titanium backup for others which i only use once in a while.....
my last hopes are on froyo final and the above mentioned solution...i am going to try it soon...
In my experience most of the battery takes 3G mode, especially when active HSDPA. If I am using only 2G mode phone can withstand more than 2 days, which is a good result, but in the 3G just 1,5 day. Remember that at the time did not use the Internet to disable the Internet connection, it should help you.
20-24 hours.
I'm using nessy right now and getting the best battery.
I call a lot so this is the right rom for me after around two to three hours of talk I'm still left with some juice. Turn my sync and use apn off application , least screen display brightness got a widget for turning it high when I need it. Use mostly wifi for internet.
on CM7... 12 hours and it's dead. without wifi
well my battery life has improved by these steps:
1. Wiped all my data,cache,battery stats ,everything(though i don't think this is necessary).
2.Flashed froyo final.(I am now on devoid forever and will test my battery life on it)
3. Checked 2g networks only in settings-networks-mobile networks.(Dunno how much that helped me )
4.Install only apps which are necessary (i have around 50 installed)..and the rest you can restore via titanium when you need it....
and now my phone eats just around 1% per hour of idle time....(it's improved)
I get around 2 days backup on Devoid final with franco 16.1. Only 2G, 1-2 hours calls, sms, bit of wifi tethering, Browsing on edge for 1-2 hours,facebook, and no gaming
In Cm7 maximum around 20hours that too without wifi, or any fancy stuff. Just 30minutes browsing on 2g.

and yeah install watchdog task manager to know if some app is using excess battery..

Dude uninstall..that watchdog thing it runs in the background and eats up battery... don't use any kind of app..that is so called battery saver.. they should rather be called battery eaters... and yeah it is always recommended.. to wipe cache.. that saves battery..

IMO it is hard to compare battery use when the phone is active because it depends on too many factors: widgets, wi-fi usage, 3g/2g, app, brightness, etc.
What can I tell is that my phone in sleep use 0.6315% battery/hour
Anyhow I charge my phone every day because I play a lot with it.
I'm using OpenOptimus 1.172.1 and franco's kernel 16.1
My routine usage goes like this: 6am to 7pm (13h) plays non stop music (fmradio or poweramp). No wifi no data, 2g only.
During that time, I use 3g data for browsing, chat, emails and youtubing for a couple of hours more or less
7pm to 10pm: 2g only, no data, wifi on. I do a few browsing around 30min top, synch stuff with dropbox etc
Finally after 16-17h of usage it has around 30% - 40% of juice left in it. Then I put it for charge, go to sleep and start over again next day
On weekends it's a completely different story. Especially when i'm fooling around with GB roms i might have to charge it 2 times a day

Hi
My battery lasted 2 days on CyanogenMod7
Now that I have Gingerbread 2.3.4 by andy572, it lasts 4 days on a minimal usage

That's weird. I flashed and reflashed andy's rom two times and I had the same issue. 10% battery drain every 2 hours. IN IDLE.
That meant my phone was dead in 20h in idle mode, 12-14 hours if used for texting and calls.
I am also using Andy's rom and kernel, with a normal use, daily 30-40 minutes with wifi on, 30-40 minutes talk and 9-10 sms. I mention that 3g is off data is usually off so since the last full recharge passed 3 days and i am still at 28%. performance is also great. Love this rom

What's your overnight battery drain with CM7?

Just curious what everyone's overnight battery drain was using CM7. The lowest mine will go is 10% over about 8-10 hours of non use, only one gmail account syncing, nothing else. This is using every variation of CM7 (stable, nightlies, and weekly's)
Using the new 2.3.5 fruitcake I am get a consistent overnight drain of only 3%.
I have tried everything possible to match that, but I'm beginning to think it's not possible.
i only have facebook but log out when i go to bed yet my phone still drains at least 10 percent every hour haha
I'm loosing also between 8 and 10% of battery overnight. I tried to optimize it in anyway including reducing brightness, deactivate services etc but still the same result. This is something which I hate with CM7 previously I used SGS and I had the same problem there. I don't know if it is a general CM problem or just these two phones.
Strange

That's really weird. Ever since I've started using different versions of CM7 I've averaged 2-3% drain overnight. This was both on the stock kernel and faux's enhanced stock. Only thing I would do before bed is turn airplane mode on.
Lately, it's been 3-4% drain overnight but that's probably because I've been installing a lot of apps (Can't pass up those $0.10 deals). Even after switching to Clemsyn's 1.0GHz kernel I'm getting the same amount of drain. Have you guys tried flashing a new radio or setting up SetCPU profiles?
Attached pic is with a little over 2 hours screen time.

I imagine the op is not refering to stand-by in flight mode. Personally, if the phone is in flight mode sat at my side while I sleep then I might as well switch it off.
My battery drain is probably around 15% over 10 hours on Ba2tF, Faux enhanced stock. That is with 3G on and background data, including syncing gmail/contacts etc. It is certainly higher drain than I would like and was getting on stock Froyo.
However, I think ~2 days standby is not ridiculous - 1% per hour will get you over 4 days which I think sounds reasonable. We all fall foul of spending hours of our time trying to squeeze a bit more life out of our phones but most people reviewing them these days are quite understanding: "the battery life was OK - it got us through a day's use"...
Yes I agree but we have a great large battery and still can't get better life. Is it the CPU draining the battery so much? When I'm on 3G and using the phone actively during the day the battery last for no more than 10 hours. There should be a reason why the CM7 is draining the battery faster and this is what wir are trying to realize. If it was 10-15% more than ok but it is almost 50% more than a Stock ROM

I'd agree except I use my phone as my alarm clock , but point taken. Without airplane mode it would be 5% tops.

I'm in the same ballpark on Weekly#2 and both custom kernels. I usually get 1.5-2 days with moderate use, wifi, syncing, etc.

It seems that new build of GB gets pretty awesome battery life compared to most older builds or custom roms. I believe Nottach pointed this out when he initially started playing around with it for Darkside. If you haven't tried re-flashing your radio, I would definitely give that a shot. (should be in the OP of the CM7 thread)
I don't think that flashing new Radio will solve the problem. CM7 doesn't come with Radio anyway. Initially I though that the problem is in RIL but after suspending all the data transfer for a night without any change I'm not so convinced that this is the problem. Unfortunately the CM7 mail client is also not perfect and after removing it I'm getting slightly better battery life.
Just for the information.
I loose 3-4% per night (7-8h) in airplane mode.
Weekly 3, Clemsys 1.4 Elite version with a more aggressive memory timings, set at 1GHz and UV with SetCPU .
Good for me.
3-4% in Airplain mode is not an option. We are trying to figure out where is the leakage. I'm pretty sure that it is a common for all CM7 branches.
I lose 1 percent overnight with everything off. No wifi or data is on and nothing syncing in the background. I have never had a phone with such amazing battery life. Not even the old Nokia 3310 or Sony Ericsson K800i compare to this. I am pleasantly surprised.

Yeee right and mine is getting 100000 years on standby with Nuclear Battery from StarTrec
My wife's galaxy loose only about 3 or 4% after 9 hours sleeping at night with 3g, data, sync and facebook on. The romantic is Insanity which is based on cm7.
I'm not devs so I can not figure out what's different to my atrix which always lose 10% over 8hour at night with same setting.

I am losing like ~30% battery overnight (7-8 hrs) with CM7, faux's kernel v022. I have WiFi on, data on with syncing.
Losing 4-5% overnight, no airplane mode.

+1. This is where I'm at after leaving wi-fi and sync on the last couple of nights.
