[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.

Well, Google says "something between 8h and 740h". Are you getting 740h out of your phone?
I asked here, where people know their phones and how to get the most out of it. And instead of stupid ranting you could have just stated the battery life you get.

It's not a fair question because it depends on your usage, can be between 6 to 30+ hours.
If you get any smartphone then prepare yourself to have a charger nearby anyway.

I like the battery life, but I also grabbed the Samsung Armani 1650Mah battery which is the same physical size as the original and I really get good battery life now!...

Obviously, which is why a (smart) person would have posted like I did.
Unfortunately, everyone hates on people asking about battery, instead of helping. The truth is: once you figure out what's eating your battery, it's easy to set it up to last as long as you need it. Using one of the most power-hungry ROMs (CM7), I achieve 12-14 hours easily--and that's with hours of internet browsing--which is plenty to get me through the day.
If I only send a few texts every hour, and a couple calls in a day (ie., at work), my phone will last for 2-3 days easily. And, again, this is on a ROM largely regarded for having the worst battery life.

With normal usage its the best phone with the best Battery i ever had luv my i9000

Love for the Nexus 4

I don't even know why I'm bothering with this post really.
It's like I really love this phone, I love the size, the feel, the look. I love it.
I just cannot forgive the battery life. The camera, which to be fair is crap, I can let that go. But that battery life, oh dear me, even after rooting and trying every rom or kernel known to man I can lose over 30% battery life with just an hours 3G surfing, watching that battery percent whittle away whilst I use it is painful. That, and then the fact it gobbles up battery life (media server) just playing songs, it drives me insane.
Such a shame, vanialla stock android id beautiful, I can't go over to samsung because of my hate for touchwiz, and HTC suffer similar battery woes.

cheers for that, ill be sure to go right over there and post in there as well... thanks so much for all your help, you're an inspiration to us all .

My battery life is fantastic, the N4 is one of the best Android phones I have had in this respect. A day of moderate use, and I always have 50% remaining...
Rather than crying, try posting your battery stats.... It's possible it's nothing at all to do with your N4, but a rouge app.
Also give the Qualcom battery saver app a go.

I love my N4, but it doesn't make me a coffee in the morning. It sucks.
Btw, i do think it can have better battery life, i blame JB, which to me feels like testing grounds for the next big update.

[TUT] Extending Battery Life

So our phone has a lithium Ion battery right? Well heres some things most people do not know about this type of battery.
Sorry if this has been posted before!
Li-ion batteries begin to degrade as soon as they start to be used.
One cycle is based on a 100% depth of discharge (e.g. discharging from full to empty), the potential number of charges can be increased by not allowing the battery to become fully discharged before topping it up. For example, allowing a fully charged battery rated at 500 cycles to drop to 50% before recharging could potentially triple the number of charge/discharge cycles to 1500 before the battery capacity degrades, thus increasing the batteries overall lifespan. However, this also means the battery will need to be plugged in more regularly.​
This means that keeping the phone topped up, and not waiting for full discharges will potentially extend the battery life of the phone.
In no way am i saying this a definite thing, as i do not know, and this wont extend your screen on time if that's what your after, it will offer you the same amount of screen on time, for an extended period of time.
So to conclude, charging little and often can extend the life of your battery. In theory anyways. I read up on this from a few articles and websites, too many to reference, but this is the combined knowledge i found.

There are still a lot of people who thinks that you must discharge to empty.
This was required when NiCd batteries were in use. Li-Ion are different.
Thanks for posting that! :highfive:

I have read on Note 3 forums how people cry about their battery life.
Thwir new software upgrade lowered thwir screen ON time to "only" 4-5 hours from 6-7. Whereby I am more then happy if i get 2-3 hours of screen time.
It makes me question my battery and software...

Friend, I wrote it looking at the topic of the thread. Hope this will help people who are looking to optimise their battery by tweaking some settings in CM 11.
At least helpful to those who have subscribed to this thread !

@sPEADy and @prem911 what ROM + kernel combos are you guys using ? :good:

@sprite048 I am using the nightly form 07th January.......and all defualt CM did'nt change anything

best battery saving strategy:
1) turn off wifi and 3g
2) put down your phone and pick up a book to read
3) dont touch you phone, use the landline to make call and laptop for messaging
right, speady?
Just kidding, WiFi and 3G are actually your battery killer. I'm currently using CM11 and can have 3 hours light gaming (Plague Inc.) with 700MHz CPU and 200MHz GPU settings. Another tip is dont use background process (such as news, email or even swiftkey; Google location accessing as well), they do wake your phone up regularly to sense if you have connection with the Internet Lord.
