[Q] Looking for the most battery efficient rom/kernel combo

I am going to be traveling in Asia for a month. I don't need any of bells and whistles and I want a phone that is very stable, very energy efficient and GPS camera definitely has to works. Which rom/kernel will you recommend? any setting tricks? Thanks
I have tried Rod's MiuiMod, CM6.1.1, CM7 and many others.
I found that CM7 + WM 1/6/2011 kernel gives me the best battery life, but CM7 is still not in stable stage yet.

I have had the most battery life with Enomthers Rom, currently he is away on personal responsibilities but his latest stable rom is very battery efficient!

I have no recommendation as to kernel/rom combinations, but for long battery life I use this:
http://www.amazon.com/Seidio-Innocell-Battery-Google-Replacement/dp/B003FSTBP4/ref=sr_1_2?ie=UTF8&qid=1296521084&sr=8-2
I got really tired of barely making through a day without having to recharge so I bought one of these. I got mine for $61 on Amazon and free shipping. It's 3200mah which is over twice the stock battery. My first full charge/discharge cycle I got over 34 hours of moderate usage and it's supposed to get better after a few charge cycles. It does make your phone about 30-40% thicker (comes with it's own custom battery cover), but for the battery life you get it's well worth the added thickness. I also find it's a little easier to hold on to.
Anyway, maybe not the solution you're looking for but for me it was well worth the money.
Just my 2 cents.

That's one big battery Thanks tho, but I want my N1 to stay small.

I second the recommendation for Enomther's. Rock-stable.

I have no combo recommendation cuz I haven't found a really good one yet. Right now I'm using cm6.1 and wild monks kernel. It's been decent for me. But I suggest using set cpu, put on power save mode when you don't use the phone. It'll be there forever. Turn off data connection and gps as well. Also using less like half the animation helps speed up the phone and saves battery too.
Ps I'm combining inexus theme too and their icons plus the animations are amazing! My phone looks colorful as hell!

Lol yea it does add some bulk but it sure is reassuring to know I don't have worry about my battery dying before the day is over. I use my phone a lot and don't have time to really recharge it much and I don't like the idea of carrying extra batteries so this works very well for me.

I haven't done too many Roms, but miui has given me the most battery life out of stock, cm and miui.
I've been travelling and I managed to get 4-5 days with minimal calls and very light usage. If you use it normally with wifi and regular calls, 2-3 days is usually the limit.
Both these numbers are with auto airplane mode during my sleep hours.

What i have heard is that CM7 is 20-30% more efficient with battery life than CM6

In my personal opinion, CM7 Nightlies are really stable. After a real heavy usage i.e. playing games, surfing, calls, messages, i get about 15 hours a day.
My phone is fully charged when I leave at 8 and by 8 pm battery will be somewhere between 40 and 45 % left.
Bugs are there with CM7 Nightlies but so far I haven't had any problems with it.

Recently I've been through about 3 roms, and of the three (rod's, micromod's own GB aosp, and leo's GB aosp, leo's gives me the best battery life.
It might be because he incorporated the battery driver, though.

Should i get this phone? Advice pls!

Hi all. Im due an upgrade i summer. Im looking At this phone or the desire s. But is this phone buggy? Is the dua core really something special? Reviews on the 2x arent too good atm, the phone has many negative points abt it! It was like that with my tg01. I got it because it was the worlds first 1ghz phone. (just like this is the worlds first dual core) my tg01 has soo mamy bugs with it and it was rushed out. Is the 2x like this? I hear it is very buggy. I dont want to get another phone like my tg01 where i rely on custom roms for the phone to be usable.
So long story short, is this phone good? Is dual core something special? Or is speed more or less the same as single cores? Some ppl say that dual core is not needed with android.. Is this true?
Sorry for the quick messy typing (not on pc) and looking for some quick answers!
Cheers

anyone?

Its GPU is a bit ahead of the Samsung's... The CPU is far ahead. In Smartbench 2011 I score 4142CPU and 2953GPU and no samsung devices are even on the charts (with 1.4ghz OC but still stock is a lot better, and I would recommend installing a custom rom...). The call quality can be quite bad until you flash the baseband but after that it should be great. I have nothing bad to say about this phone, and when 2.4 comes out it will only get better (2.4 is rumored to come with real dual-core support)

Even though mine's been working quite well for past 2 weeks as my daily phone, there are also people who are quite fed up with theirs.
I hadn't read xda's user reviews prior to getting mine, but if I were to get another 2x now, I would wait for LG to provide a firmware update that significantly reduces the lock-up/reboot/battery drain issues. It's just to be perfectly sure that I will get one as stable (or more so) than my existing 2x.

I believe the battery drain issue can be fixed manually. just need a through check on whats running and how

thank you all for replies!
(xilw3r sorry i have run out if thanks!)
i
so most issues will be fixed with updates? but does the phone need to use a custom rom to be usable? is lg's ui good?
and is dualcore really much of a difference? do you notice a giant speed difference betweeen other android phones, or is it overhyped?
is battery life good on this? how long heavy use can it last under wifi?
im really stuck considering this and the
desire s

LG ui is laggy and a personal choice, i use lancher pro plus. heavy use and wifi battery lasts a few hours.
Battery doesnt last a day with low usage for me. 5-10% per hour on standby. With 3g on and mail twitter etc sync every 60 minutes. my old hero lasts longer with heavier use

Can't comment much on the performance or UI as I moved over from Symbian. Though, it's much smoother in its user interaction than my son's LG Optimus One, but that's single core, 600mhz.
On days that I don't play much with it and actually use it like a typical work phone, the battery remains above 50% by 6pm. I think usually about 1 to 1.5 hour talk, hourly email auto-checks, less than half-hour of browsing and less than 20 SMSes. I am not a heavy user: I don't IM at all, nor GPS or game much. Just typical work-type usage.
Note: I switch off wifi when I am out of the house and rely on 3G for data connection. I find that keeps the battery lasting longer.

then you have some application/service/process running roque
Mine easily last 10 hours in standby with only 1% battery use (wifi and 3g and autosync enabled)
if you have 5-10% drain per hour on standby, you have some application/service/process not going to sleep as it should, using cpu and power, and preventing your phone from entering standby mode.
Thats not a problem of the phone - but a software issue that you as user need to investigate and solve
with low usage I easily get 2 days running - with moderate use 1½ - and with heavy use 1 full day.

No strange processes running here, spent a few days of testing with different roms aswell drain still exists
Sent from my LG-P990 using XDA Premium App

thanks fir responses! i was gonna say 5-10 drainage in an hr is bad! is the a common problem? i heard abt these battey issues!

Battery usage:
16h after power was unplugged, I still have around 40-45% of battery. Low usage (WiFi/3G on, a few calls, gTalk, but no email sync activated).
ROM: 10b

I relly want this phone but im not sure about it anymore.. i read so many many many big bugs about it, and seems that almost EVERYONE is having them..
optimus one was a great phone with dew bugs, why cant they make the same quality on a HIGHER END handset lol :S ?

If you look through the forums of any phone, there will be a lot of people talking about how they have some sort of problem.
Nexus S

yea but o2x is A LOT, mean u have 60 page thead about reboot issues.... that doesnt look too promising ..

You can always return it if you have too many problems
Nexus S

The stores have em already, G-slate and G2x. Played with both today, I know the manager in store but before somebody make a dumb comment pertaining to that, aint nuttin top secret and no special info was bestowed on me because of who I know. The stores just have them stocked already. The slate is nice though, good build, nice size and weight, kinda reminded me of the ipad but lighter. Honeycomb makes our phones look like gameboy colors.

But the G2x was also better than my expectations! By far blows most of the others out of water.

Battery problems being caused by..?

Google Plus?!!? Picked up my N4 over the weekend but have been massively underwhelmed by the battery life, coming from an S3, with a similar rated battery and all that extra bloatware, its hard to see how the N4 fares so much worse. Anyway, Ive been poring over the battery stats and plus kept coming high up the list as a high consumer. Disabling G+ has made a MASSIVE difference for me. YMMV but would be interested to hear if anyone else has had similar experiences, or tips on battery?

My battery life is not great, either and seems so effing stupid to buy this wonderful phone for all its great features then have to turn down the brightness and disable Google Now and all sorts of other stuff just to be able to get through a day of use. It's like buying a supercar and having to drive it in valet mode all the time.

I doubt, don't quote me on this, that haptic feedback will make a noticeable difference

Google now is the problem if you ask me - it's constantly using GPS which kills battery life. Shame cause google now is cool. I've turned my GPS off and will see how it affects thigns (I suspect I'll see a huge increase in battery life)

Actually haptic feedback can be draining depending on your settings. I tested this on my last device.
Just turn all this crap off. I use a widget that shows the weather, clock and has switches. I turn off auto sync mostly, etc.

REALLY bad battery life, is this normal?

Heya,
I've used my One for a few hours now, I'd say moderately heavy use (checked facebook/twitter, downloaded some apps, watched a few youtube video's, played Dungeon Hunter 4 for 30 minutes or so, checked flipboard).
I'm amazed by the poor battery life, especially since all the reviews were so positive. Will it get better? Could I have a faulty battery? This is nowhere near the 14 hours people have been talking about...

With what you are doing i lose like maybe 5-10%. Your battery is faulty for sure!

you can't tell yet. @Zepid, look for better battery stats xda edition and install it and post the screenshot for kernel and partial wakelocks, other and process.

It's hard to really tell with the default battery monitor, try BetterBatteryStats or GSAM from a full charge and go from there.

Also turn Power Saver on. It limits the CPU to 1.1GHz, and won't even affect gaming performance, or anything else for the matter except benchmarks. Click on the Power Saver option to customize what gets turned on/off.

You should check out the thread that talks about battery saving tips. It helps a lot and make sure you install a custom Rom such as trickdroid.
It's very battery efficient.

Don't forget that if you install a custom ROM, you'll need to root your One. That also means loosing your warranty

DH4 is a beast on battery in my experience. It is hard to play that game and not burn a ton of battery.
Anyway, when I don't play DH4 I still get 5 hours screen time. That's without power saver, auto sync disabled, and Lux adjusting screen brightness. I'm sure if I used power saver I'd get much longer.

Seriously, give it a couple of days!

I have found my battery improved after about a week of having my phone.

Graphic intense games like Dungeon Hunter 4 EATS the battery.

Thanks guys, the Power saving feature definately seems to help, and it's not slowing down the phone at all. I'll give it some time and see if the battery life improves.

before you start combating symptoms, you should first try to diagnose the disease, so you can combat the underlying disease, follow my first post

I have to agree, my battery life is pretty poor. I'm going to give it a week and hopefully it clears itself out.

You should allow more time, at least 2 or 3 updates, to iron out the biggest bugs. All manufacturers need that time, apple en Samsung too.

Speculation for Nexus 4 battery life improvement

Got the Nexus 4 on release, so far it has been 8 months and never regreted buying it. Many people bash about the poor battery life of the N4, and praise about how awesome the note 2 battery is; it does makes me think twice about selling my N4 for a note 2. Before 4.3 I get a pretty decent SOT, on average about 4.5 hr. Sometimes it surprises me with SOT in the 6 hr range(attached pictures, before 4.3 update).
After updating to 4.3, like many other people, Ive experienced a battery improvement. Now on average, I get 5 hr + SOT. Im on stock everything, no custom roms or kernels. Another thing Ive noticed after the update is that the phone doesnt heat up as much, and it's this that I believe lead to battery improvement(less heat =more efficiency). This phone truly has a potential, and Im holding on to it, to see what it can do with the next update: Key Lime Pie.

Aha, and I don't suppose you could post this in this thread?

I think the majority has a **** battery in contrast to the note 2. I don't know what yoi do with your phone in that time, but I would never get such results. I think not even with uv

I dunno why, but sometimes it is awesome while other times it is not(3.5 to 4 hrs). I realize the battery life is much better when you don't use auto brightness. Here's another picture. Totally stock.
