Best setup for battery life in MIUI V4?

I'm currently running 2.4.6 along with nyan colonel 4 but so far I'm not too pleased; I'm getting about 5-6 hours with medium use on a 1800 mAh battery.

Try turning off 3G (mobile data) when not in use. I was getting 6-7hrs w/ it on & now I can squeeze out 12-15hrs. However I left it alone it went 30 some odd hrs w/ only 30mins of screen time though.

Nuh uh, that's not gonna fly in this thread. I shouldn't have to be turning off my data to get any semblance of decent battery life. I really do want to get this to work though; I love MIUI. Unfortunately it seems the GB version will never be complete as everyone jumped ship to ICS and the ICS version is awesome but seems to get crap battery life even on 4.0.4

you dont HAVE to turn your data off....but if you wanna save some battery that is one of the best ways. if your phone is in your pocket and you dont need it, why have it on suckin juice....try juice defender, i use it with any rom i run and it helps...play with uv in nstools, just dont go too crazy with it.

Uh lol? He just gave you the best tip and you turned it down, you must not be interested in improving battery life, if you're constantly using data and have over 2hrs of screen time you're asking for crappy battery life, and unless you are always receiving important emails, you really don't have a reason to run it 24/7, if you're to lazy to turn it on and off, just use juicedefender, and it'll do it for you. You'll have to make some sort of sacrifice, whether it be monetary or personal. Phone usage is everything, get a bigger battery. Also, logging out of social networking apps when you aren't using them helps as well. I find I have very nice battery life on MIUIgb

I know that turning off data can save me battery life. That's not the point of this thread. I figured it was implied I was talking about different kernels and versions of MIUI V4, not the way I use my phone.
On that note, what's your setup with MIUI GB? I've been considering going back but I'm turned off by MMS STILL being broken

Sorry dude but that's the wrong question to ask. By now u should know that every phone is different if its what kernel to use & what setting to use this or that app than its simple trial and error. When we were still on froyo I couldn't use one of the very popular kernels bcuz it drained by better like crazy it took me a few weeks but I found the perfect setup to get good battery life. & sorry for misunderstanding your intention for this thread.

Alright.. well I misunderstood, it mighta been better to include that in op but it's whatever now lol, I'm using shadowkernel MIUI, and... 100-800Mhz governorndemand, schedular: Sio. And yes MMS has actually been a pain in the ass today for me, I'm considering going to AOKP again lol. I will apologize if I sounded rude in the previous post though, I didn't understand where you were coming from.

Is dropping down to 800 MHz noticeable as far as performance goes? Also is MMS the only problem you have with MIUI GB?

[Q] How to tweak rom/kernel for best batery life

Hello, i'm using typhoon latest rom with latest kernel from dorimanx (7.1A), but im gonna go on vacations and i really need my phone to last as long as possible, is there any way to tweak rom or kernel for better batery life? thanks

What sort of battery drain do you currently get on standby? Can you tell me the reading in ma from CurrentWidget? If it's 3-5 ma with mobile network/wifi/bluetooth etc on and 2ma in airplane mode then you're fine,but if it's higher it can definitely be improved.

If you don't plan to use mobile internet connection then disable 3G and turn 2G mode only. Turn off as many widgets as you only can, disable Location Service and auto sync. Install apps on phone memory only.
Also Dorimanx kernel is a hell of battery drainer, use another one like stable Tytungs etc.
Use dynamic/powersave CPU governors or use CPU speed profile apps like SetCPU and make several profiles for it.
This is only a few of tips we can give here.

im getting between 10 to 15 ma with 2g on and sync all the rest is off, and im using smartassv2 governator i dont know if this can be improved .. and i really like dorimanx kernel becouse it feels faster then tytung and it gets less hotter becouse right now is really hot these days and i nearly cant use the phone with tytung kernel becouse it gets crazy hot :O

Well the apps I use to reduce my battery drain are JuiceDefender and SetCPU. Set the profiles to be 245-576 Mhz when screen is off (smartassv2) and whatever else you like when screen is on. I never had any overheating problem with Tytung's kernel though. It was the most stable and just as fast as Dorimanx's kernel IMO. Still, using ICS now so I can't really judge about the newest versions of each of them.

I think his kernel is the same in battery drain over any of them. Ive tried them all. If anything, seader_r9 was the best and it was only a small improvement. My battery life is pretty short, but im a HEAVY user. Constant web browsing, constant text messaging contant GPS. And it lasts for the majority of the day. Now i have an .sh script which helps tweak the smartassV2 settings. I get about 110-200ma drain when doing simple web browsing or replying to a text.
One must also keep in mind that the ROM has a major part in battery drain as well. I heard from many users on here that MIUI has the best battery life. All in all i think any kernel you choose will have reletively (i spelled that wrong -.- its still early ) the same battery drain. It really comes down to the amount of use your phone has. But as stated before, turning off data greatly saves the battery as does turning down the screen brightness, fyi, automatic brightness sucks battery life too. Plus android does a horrible job polling the light sensor -.- it shouldnt take an average of 3 seconds to get the changed light value..
Theres not much 'tweaking' you can do to give you like an hour extra of battery life. Our batteries are only 1350mah batteries and thats really small for such a huge screen. My Touch Pro 2 has a 1500 and a much smaller screen. There are a lot of good aftermarket batteries on ebay that you could get which would extend your running time.

thanks guys, im gonna give a shot to tytung kernel, but im also gonna take a look to the aftermarket baterys

Typhoon rom support undervolt so if your phone is gettin' hot I suggest you to tweak the voltages as explained to original thread first page, it makes a big difference compared to stock.

Good advice here. There's a lot you can do (as already advised) but always some performance tradeoffs. The standard HD2 battery is only 1230 mA... not 1350. Smartassv2 in DM's kernels is excellent for performance and settles down nicely in standby - but it will pull-on your battery when used. There's no substitute for keeping a few extra charged batteries around (when you need them), along with AC & DC chargers + cable, in a small carrying case.

You don't need to use dorimanx's latest kernels, his stable kernels in fact do a better job at not overheating and have only 2ma drain on standby. I know 5.9, 6.3, 6.4d, and 6.9A (ics hwa) give a great battery life.

Wow, in standby im on average around 7-3mA with the occational spikes when receiving texts or messages over wifi. And when on data its about the same, just not as often in the 3ma range.

Which apps are running in the background? People constantly say that task killers make no difference yet whenever I've opened something and haven't killed it I get a higher battery drain than normal.
Also, use JuiceDefender and SetCPU to lower the drain.

[ICS] We need your help... Battery life...

Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.

He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.

PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.

Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.

4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.

-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

MX battery life?

Hi! I got my MX couple of months ago, and I can tell I love it. Anyways the only things I wasnt happy with were the battery life and reception, and so I updated my phone's flyme os yesterday. (from 1.0.3 to 1.1.1)
I assumed the update would fix the issues ( as I think it did for the reception ) but the battery seems to be even more horrible after the update.
It seems that after the update my MX didnt even completely charge up. I put my phone on the charger at around 2:30 and unplugged it at 13:30, so it was on power for about 11 hours, but it didnt even charge itself completely in addition to the fact that it stopped actually charging at around 8 o clock as we can clearly see from the "today" screenshot.
Then comparing it to the "yesterday" screenshot with 1.0.3 we can tell it charged itself up completely.
Ive got the new 2core model with the updated 1700 mah battery (which should have the best battery life of all of the mx models) and this makes me wonder what is the battery like on the other mx's if this is normal. And yes my phone was showing the charging animation on the screen during the time I mentioned earlier in the message.

Thanks for the tip, I'll try this right away. Flyme will backup all data, right?

Except apps. If you have it enabled.

1.0.3 here, quad core model, my battery is fine, gets me over a day with normal use.
However I admit that it could be better.
Its also well known that 1.1.1 contained a bug that ate battery, so stay away from that firmware.
I didn't test 1.1.3 yet.

Thanks for the info. Im currently on 1.1.3 and the battery seems even worse than it was. I really dont know what to do - the battery runs out in just couple of hours.
Hows your reception? Do you get good speeds all the time ? Did the update have effect on that? Mines horrible.. ;s

Try to restore as less as possible. Disable WiFi never sleeps.

My MX arrives this week and I'll be measuring the battery carefully to see if I can't find a replacement. (Yes, I realize it's not supposed to be "user replaceable", but the teardowns confirm that it is if you've got the patience and dedication. Here's hoping there is a higher-capacity battery in the same form factor.) Apps are nice, but more juice is better.

After upgrading restore only as less as possible. Never use a full restore with titanium etc.
Disable WiFi never sleeps option.

Where can I find that option ?
And I've never heard of titanium, haha.

Settings - WiFi - menu key - Advanced
One more thing: disable sync for unnecessary accounts

Huge thanks. Already disabled all sync except flyme.
1.1.5 is out, do you think I should try that? Theres no thing mentioned about battery in the changelog but there's some magic in updates sometimes, isn't there?

Hehe that's true. I use 1.1.5 and it feels pretty good.

1.1.5 is nice, however there is a bug in android terminal emulator.
The osk wont work until you change the input type setting to word based.
I also suggest prerooting the image, Ubuntu works nicely on it too.

What kind of changes have you experienced? Anything with battery life ? Smoother?

Yeah I heard about that bug, but that's an easy fix isn't that Also never ran into the need of terminal on my MX.
There was someone on meizume forums telling he could upload a prerooted image of 1.1.5, and as I have 0 experience on how to preroot the file I wish he could do that. You see I'm a newbie - don't just tell me to do things, please tell me HOW to do the things aswell ^^,

Kedros uploaded one already. You can just fetch his.

Battery is 71mm x 35mm x Unknown Depth. If I can find a few batteries matching the length-width, I can start trying to transplant them into my MX quad core.

Please keep us updated on that.
I would love to stick a higher capacity battery in there.

[Q] Anyone can explain ? :)

So I have had my Nexus 4 for 7 exact days, was suffering from a terrible battery life of 1:30 hrs MAX screen-on. Until I flashed CM10.1+Franco's latest kernel and my phone has a 3:30 hrs of screen time on ! - I tried AOKP with Faux and some other rom combinations...Any one can explain why?
And clearly the battery life on WIFI surpasses the one on 3g.

It probably has a lot to do with the "msm_hsic_host" kernel wakelock that is present on the stock kernel. Flashing to either franco or faux kernel is supposed to be a great way to fix it and increase battery life

Because Franco Kernel is like magic?
Edit: oh hey! you're the same guy from yesterday I suggested Franco Kernel to and pm'd me for additional tips

1:30 screen time Max? Damn.... Do you use your phone as a satellite? And WiFi IS ALWAYS better on the battery than 3g, that goes for any phones.

I suggest using https://play.google.com/store/apps/...yLDEsImNvbS5iaWdleWVzMHgwLnRyaWNrc3Rlcm1vZCJd with those kernels. I use Franco's paid app but Trickster is a good free alternative!

Thanks for the suggestion. Tinkering with phone settings is not in my priority list, but knowing what the kernel is doing with my phone is definitely useful if I decide to tinker later.
And free phone state knowledge is priceless (as in it has no list price :cyclops

Not sure if it has the ability to disable logging and events (i think it does). You can disable those two features for better battery life (very insignificant but every bit helps, right?) and you can disable fsync if you choose to (more IO speed, less stability mainly if your phone was to randomly reboot).
Plus the free color changing is always nice to have.

3 to 4 hours with screen on is normal battery life for a stock Nexus 4.
It sounds like you were running something that was draining the battery.
When you updated the phone, the new ROM turned off the culprit.
The battery drain is not necessarily caused by an app, it could be one
of the Google services or bad reception. Even changing the phone's default
settings can result in much better battery life.

This might be a stupid question, but could switching from stock kernel/ROM fix my antenna radio reception bull**** issues?
