[Q] How to change sync frequency in MIUI ROM 1.2.4?

I just flashed MIUI last night and noticed that my battery is being sucked dry pretty fast. I suspected that it is due to sync being switched on. Where can I make adjustments to the frequencies of the sync?

Either from the app or Settings>Personal>Accounts & Sync
Although I didn't have ANYTHING setup last night when trying it and lost 6% in about 10 mins - something's not right

Try resetting your battery indicator http://www.miui-au.com/howtos/reset-battery-indicator/. It is also recomended somewhere on the miui-au.com site to not charge your phone while flashing because it is somehow disruptive for the indicator.

I know all that, I wipe:
data/cache
dalvik-cache
battery stats
rotation settings
before flashing ANY ROM. Battery life is still crap

The weird thing is I wasn't charging the battery while flashing. I find it a bit surprising for MIUI 1.2.4 to be quite a beast in battery usage.

What would you consider a good battery life?? I flashed to 1.2.4 and it seems to last me all day without any problems?BUt I have noticed slight 5%-8% drop in the 1st hour or so but then it stablises throughtout the day. Ive not tweaked my phone with setCPU and I dont intend to either.

Something is rly wrong with your MIUI. Anyway, never use that Kernel which comes with miui. Use Vork or Coutts Kernel.
pls download current widget from market and test how much mA it drains in "screen off". im using miui-au 1.2.4 r2 with vork kernel and im losing 1% per our with wifi, sync and gps on. it uses 4-5 mA with screen off.

With previous MIUI builds, and with my own ROM I'm using now, I can go from 7:30am til midnight and still be on circa 50% battery. This is with my normal weekday usage. It goes down to about 30% by end of the day on weekends as I use the phone more
This build drops 5% in a few minutes and I just don't see that as being any good

I don't need to download anything, the ROM was dropping battery with NOTHING setup except for Wi-Fi. I didn't even setup my Gmail account to get my contacts!!
I think I can skip the obvious as I know full well what I'm doing and never had this issue with previous MIUI builds, and I never use the stock kernel - I always go for a Coutts one before first boot

Cyanogenmod 10.1 terrible battery life

I have recently installed cyanogenmod 10.1 onto my galaxy s3. The battery life since then has been very poor. If I leave my phone on without even using it, it drains about 1% every couple of minutes. When I look at the battery it says that the process of "phone" is taking up a huge amount of battery. Can anyone tell me why this is or how I can fix it?

Generally these issues are user related and not ROM related.
I was so frustrated with some of the ROMs when I first started out but then realized I was doing a few things wrong (mainly because these ROMs, including CM10 have very decent battery life).
First, I would recommend a clean reflash:
factory wipe / reset
wipe cache (some say twice)
wipe dalvik cache
install ROM
after rom loads, wait 5 minutes (don't touch at all) then reboot
now you must wait.. sometimes it takes 24 hrs or so for a ROM to correctly load.
Not sure how true it is, but some say to now drain battery down, then fully charge.
At any rate, I follow these steps all the time and works great!
Also, keep in mind that most of battery issues are user related.. so think about what settings, apps and kernels are being used on your end before question a ROM. This is why waiting 24 hours or so before installing all of our "crap" will give give the ROM more time to settle.
Hope this help!!!! Happy Flashing

Thanks for the reply. However, I have looked at what apps and processes are draining my battery. And it appears it is the "phone" process that is doing this.

Just to piggyback on spenny88's reply, exactly what did you come from (stock?) and how did you wipe and flash?
This is all key as to how well your device will perform.

I have noticed something similar. I am coming from stock. I am going to guess my battery life is in the neighborhood of 10% less. I wiped everything before I installed CM. That said, this feels so much faster than stock.

Having the same issue with my Samsung Galaxy Tab P1000 (p1 in Cyanogenmod). "Cell Standby" is taking as much juice as "Screen", and I am using Wifi only. I don't even have a sim card in the device. Wish there was a way to disable Mobile Networks without disabling Wifi via Airplane Mode.
I installed through Rom Manager as upgrade from CyanogenMod 9.1 with wipe. I will try the recommendations above and report back.

Try the latest nightly (or RC4) of CM10.1. The battery life has definitely improved a bit.

Samsung Galaxy s3 intl battery drain cm10.1
I recently installed cm10.1 nightly on my international S3, it has cut the battery life down drastically and seems to drain over 10% an hour, even when not being used.
I've tried everything that i've came across by searching and still haven't had any real gain on battery life. Doing a full wipe and reinstalling doesn't help, and i've given it time for battery to calibrate; no difference. Even with wi-fi and location services off i'm getting a big drain. I've even tried switching to Slim Bean, if anything the battery was worse still.
Firstly i'm getting that Android OS is eating up a large chunk (usually above 60%) and using BetteryBatteryStats i don't see anything out of the ordinary in terms of partial and/or kernel wakelocks. I really don't wanna have to put the stock Touchwiz rom back on but that seems like the ways it's going. Any help would be greatly appreciated. Is there anything else i can try?

i find i get terrrible battery life on AOSP when i restore google through the setup. i skip thru the installation and open the play store to enter my gmail. then, before restoring my apps, i let it charge to 100%. honestly AOSP still doesnt have decent battery life, but it does improve if you play with it and try different things

I would respectfully disagree with you. I have run a number of ASOP based ROMs and find them better than stock in terms of battery life. Certainly better in terms of not making my eye bleed (as I hate touchwiz, but that is a personal preference). I find that SlimBean gets me the best battery life of the CM based ROMs.
To clarify, I get just over 1%/hour battery drain, when idle (as measured by BBS) with GPS and google sync enabled, mostly on LTE. My phone happily spends almost all the time I am not actively using it in deep sleep.
The recipe to achieve this is to disable google location reporting and history, avoid tons of widgets that constantly update themselves, disable samsung services that you do not use, and monitor battery usage to look out for rogue apps that do stupid thengs, like hold wakelocks when they should be idle. Dropping the minimum frequency to 192 MHz, and going to ASSWAX (CPU scheduler) and ROW (I/O scheduler) also helps.
To get decent performance you do need to install things properly. Which means ensuring that you don't have conflicting settings or random leftovers. I tend to dirty flash updates but you reallly do get better and more consistent performance going through the pain of a complete clean install (format system, clear cache, reload apps from the store) when you are switching ROMs. Only use TiBu to restore app data. Once you do this, in my experience rogue wakelocks are the biggest cause of lousy bettery perfromance, and you can track down and eliminate these. I have around 150 apps loaded and do not run any task manager/autokiller. My phone typically runs without any reboots or power cycles between ROM updates which equates to rebooting every couple of weeks to a month. I have seen over 2 months of uptime.
Certainly should be able to go 16-20 hours between charges which I would consider real world all day functionality. I guess my point is that rock solid stability and all day battery life is possible if you are systematic about how you do things.

[Q] CyanogenMod 10.2 Alpha (Build 3) --- great stuff, but battery drains fast

Hi,
I follow the forums here for years but have not posted yet, hence not allowed to post on the dev forum in the appropriate thread, had to open a new one
A couple of days ago I installed "[ROM][JB][4.3.1][JLS36I] CyanogenMod 10.2 Alpha (Build 3)" on my wife's phone. Until then she was still using the stock GingerBread ROM. The phone got so slow to the point of not being usable at all.
After I flashed to CM 10.2 it feels like a new phone. Lightning fast, good looks, everything works - fantastic, very much appreciated and thank you very much @ Devs!!! :good::good::good:
One big problem though:
When running the stock ROM the battery usually lasted about 2 days. Now, with CM10.2 it is empty after half a day. Since I did a full wipe before she is using less Apps as compared to before and there is no single big consumer. Just the typical mail apps, facebook etc.
When I look at the wakelocks there is one app consuming most CPU which is CSipSimple. But that app was also running before the upgrade when the battery lasted 2 days.
The screen seems to consume more power though, is that possible? Anyone else with similar experiences?
Thank you very much!

ok thanks let me do some reading.
Also yesterday I deactivated the SIP app and that helped of course. Still strange that the app consumed to much less power on Gingerbread compared to CM10.2
Thanks,

You can try out battery calibration app before new kernel. Cause there is no "wipe battery stats" on cwm 6.0.4.4. I had same problem, and its a bit effected on cm 10.2. It's free. Maybe it will solve your problem.
Battery Calibration

That sounds very good, let me try that!

I have the same issue with increased battery drain. Yet I've not been able to identify the source. I disabled a lot of services (with Disable Service), also deactivated unnecessary system apps.
Cell standby is also shown as a huge drainer, although I usually have a good signal and no losses (checked with Better Battery Stats). There are no wake locks out of the ordinary.
Now I'll try battery calibration to see if that helps at least some amount.

Actually for me nothing really helped.
I eventually identified the 3 apps that drained the battery via Wakelock detector.
Those apps are Facebook, GMX Mail (based on K9 mailer) and CSipCimple.
Before the update to 4.3 my wifes phone was running the stock gingerbread and did not have an issue at all with those apps.
Yet on CM4.3 they are draining the battery.
Once I uninstalled the apps the batter life is back to normal. Which is sad, because she needs those apps. But no other solution so far from my side....

Again the myth with whiping battery stats / battery calibration. Make a full charge and unplug the charger. This will whipe your battery stats.
And for the ones who never get this. The stats are just some data about apps consumption collected while the battery gets discharged. The ROMs are whiping them by itself on each full charge and after shuting down the phone.
This data has no Infulence to how long a battery lasts. It´s just collected to show you visually the statistics.

Thanks ... yeah well did not really expect it, but when you're desperate
At least I thought it helps with the effect that the first 50% of the battery last 3 times as long as the last 50%, but not even that changed

I had the same problem with my S4 running CM 10.2 stable. The battery was empty after 8 hours. What I did was to change the theme, and today i got 12 hours and only 20% of the battery gone and wi-fi/3g all the time. Well, I still have only one hour of screen up time, but that is how it was before... I don't know, i'm just saying! Maybe it helps. The theme i added is LunarUi 2.
All the best!

Bad Battery Life since KitKat

Hi Guys,
i have a bit of a problem with the battery in my GNex maguro.
I'm an avid Rom flasher, but when i have something that works well i usually settle with it for a while. So i flashed Cataclysm (http://forum.xda-developers.com/showthread.php?t=1995801) sometime in the last months and it was running great. Best bettery life i had so far.
Then with the release of Android 4.4 i looked for a rom to test it. I flashed XP (http://forum.xda-developers.com/showthread.php?t=2539201) and i really like the 4.4 changes.
But since then my battery won't even last a day in standby mode. I thought maybe it's an issue with 4.4. still, but even after flashing back to Cataclysm (newest release) i still had the same issues. I thought it may well be, that the final version isn't what it used to be, so i flashed another rom again. This time Purity (http://forum.xda-developers.com/showthread.php?t=2012706) aaaand... still the same problem. So now i'm pretty much lost. I also tried different kernels (lean kernel specifically) but to no avail.
My battery used to last 2+ days in idle mode. Now i can see my battery drop every minute. It barely holds over 10 hours. I already did a full phone wipe and flashed back to stock before installing cataclysm again but still no improvement.
I hope someone can help me here or point in the right direction.
Sorry if this topic already exists, but the search funtion doesn't seem to work right now and google didn't show something helpfull.
Thank you all in advance.

I don't know why you would still have bad battery life moving back to the original rom you used but.. on 4.4 it is most likely the new Google Now features that constantly listen for voice commands. Disable it by long pressing on an empty part of the home screen and go to settings. Slide Google Now Off and go to voice and turn off hotword detection as well.
I get great standby battery life on 4.4. I'm running the 11/29 ART build of cmetal(toro), 150ish hours of uptime without any issues so far.

Re: Bad Battery Life since KK
What kernel are you running? Are you just using whatever kernels come with each ROM?

I'll try turning off google now and the voice stuff and report back.
It still seems really weird to me, that the problem still persists after flashing back to 4.3. My guess would be, that 4.4 flashes something hidden that messes with the battery. But i don't know where or what.
Especially since it persists after a complete wipe (/data, /system and /cache).
Well, i'll see how it behaves without google now.

Well i used mostly lean Kernel with 4.3 roms but i can't find any 4.4 kerneles besides CM. I have XP installed right know which uses CM Kernel.

Re:Bad Battery
Make sure your governor is set to interactive or ondemand...it could be seeing power drain from being set to one of the performance settings.
It's also possible that your battery is just going bad...do you have a backup battery you can try?

It could just be that you need to replace your battery. They are only good for so many charges and do degrade.

Reporting back. After deactivating google now yesterday my battery is still ****. It's at 50% after 2h idle and 30 minutes screentime. Before the 4.4 flash it would be at around ~85-90% now. I suspect that 4.4 flashes something in some hidden partition that i don't have access to, that messes with the battery. Users on other boards report the same issues as i have.

Just checked. Governor is set to interactive. It's also the default setting.
I sadly don't have a backup battery.

Could be, of course. But it's kinda weird that the decline is so dramatic and it has to be a pretty big coincidence that it just happend after a 4.4 flash. Seems unlikely to me.
edit: I'll order a new battery just to eliminate the battery as the source of error.

Same problem here. Since I flashed Kitkat on my phone, battery life isn't enough to last a day on standby. I tried installing another kernel (ASKP) but to no avail. Please keep in mind that I'm not very experienced with custom roms and rooting my phone. Does anyone have some good tips to improve battery life?

Update: After fiddling around a bit with better battery stats, greenify and a bunch of other stuff... i still don't have a solution. I made some screenshots of my stats, but can't post them here because i don't have permission to do that...

So i reflashed swordrune's cm11 rom and it seems to be working better with 1080p kernel w/o art enabled. i'm 11 hrs in with 80% battery on the extended battery (toro btw)

Not to hijack your thread, but I'm also experiencing battery issues after flashing the XP 4.4 rom. I did enjoy it but the battery drain was terrible. Not only that, for some reason my charger drains on a 1A charger but charges slowly on a .7A somehow. I only have 1 micro usb cable so I can't test if it's the cable and I can't find any apps to check the current speed. I tried downgrading and flashing to Slimbean but so far it's been no dice.

Ok, back again. hibernated every app and system-app that was running in background. Still wasn't getting better. I then saw the only services still running are google location services. I deactivated them now to see if these are causing it.
The biggest wakelocks i have are "wlan_rx_wake" which seem to be a known problem with KK:
http://forum.xda-developers.com/showthread.php?t=2519294
I then researched again and found several threads in google groups which describe the same problems that i have. Across several devices (though mostly Nexus 4, 5 and 7).
Google seems to be aware of that issue and is working on it.

Yes, same for me. Charging is really slow since 4.4 as is the bootprocess of my phone. From the first vibrate when switching the phone on it takes ~10 seconds until the google logo pops up.

i dont know any about gapps issues bcoz not running any gapps in my phone since last year.
1. try searching for updated radio.img (baseband/ radio) if got any network issue.
2. try install trickster mod app. this app can help you for tweaking into deep sleep, also help for optimizing.

High held awake time and battery drain

So my battery on my phone seems to suck... I just made a full wipe clean install of ICE Rom 3.5.0 with cleanslate kernel, balanced pnp profile v. 22, magisk root and got a whooping battery loss of around 30 percent overnight!
I was using stock before and had around 20 battery loss overnight, which sucks and is the reason i wanted to try a custom rom.
My phone is already 4 months old and I did a battery diagnosis, which ended with 94 percent (which is good right?).
Can anyone please help me?
I don't have Facebook or Facebook messenger installed, turned of WiFi and Bluetooth Scan and Location Services.
And I'm using Greenify, although I didn't greenify any apps yet

So my battery on my phone seems to suck... I just made a full wipe clean install of ICE Rom 3.5.0 with cleanslate kernel, balanced pnp profile v. 22, magisk root and got a whooping battery loss of around 30 percent overnight!
I was using stock before and had around 20 battery loss overnight, which sucks and is the reason i wanted to try a custom rom.

What email app are you using? How have you got it synced? See how many times it wakes your device using Gsam or some similar app. This was my battery drainer (I use Bluemail). Anyway, check that out first.
20% battery loss overnight is horrible. Something is not set up correctly or is misbehaving.
Reboot your device and let it set for 2 minutes. Now go to System/Settings/Developer options and select Running Services. Everything look OK there?
I cant see your screenshot.

Yes, I lost the same amount although I had the phone in flight AND extreme energy saver mode...

I'm facing the same problem after i updated my Firmware to 2.28.617.6. My Battery Usage show 45% of ANDROID OS an 39% of ANDROID SYSTEM, I'm already tried Viper 4.1, 4.3, 4.5, 5, 5.1, all with the same problem.
I updated firmware using RUU.exe, and i already updated firmware again to 2.41.401.3 with RUU again. Same problem
I realized the problem is not with rom, all of then, stock or custom, show the same situation. Its a firmware problem with Nougat
My phone is a Unlocked version, with S-ON
Any help?

I would perform a full wipe (+data!). Reinstall your Rom freshly, and the problem should be gone.

I'm already did that, all ROM's installs i did with a clean install.
With no one third app installed, the problem persists
i'm already tested turn of wifi, bluetooth, location, put phone on save battery mode, restart all permissions
Nothing helped
The main question is thats something who did not let phone enter in deep sleep

Yeah I've got the same problem with Android OS and Android System (the wakelocks are HVDCPD_WL and NETLINK) keeping the phone awake and preventing deep sleep almost 100% of the time, which is absolutely killing my battery life.
Frustratingly, the problem is not solved with a full wipe + reflash of any ROM. I originally had the problem sometime after the stock 7.0 OTA upgrade, at which point I unlocked the boot loader, flashed Maximus HD, then the problem went away for about a month until just returning a couple days ago. I've tried flashing the latest Maximus HD, Viper, but nothing is fixing it so far.
I bet it's some kind of hardware issue. I'm almost at the point of giving up and getting a OnePlus 3.

Just sharing my experience: I tried every Sense-based ROM I could find, problem of phone not going to sleep persisted. Even tried RUU to latest 2.41.617.3, which of course wipes absolutely everything - same problem, phone not going to sleep. As last ditch attempt, flashed the LineageOS Jan 28th nightly, and the problem is gone. Phone sleeping properly and battery life is back to normal. Not sure if coincidence or what... Going to stay on Lineage for a while as it works pretty well, but will go back and try Sense again in a couple weeks maybe.

This issue started to affect my phone while still on Marshmallow, around 3 weeks ago. It felt like it started after updating an app. This is what prompted me to update to Nougat. However, the issue persisted, even with full wipes, and even with LineageOS installed.
Moving from stock ROM to LineageOS has reduced battery drain from 10% per hour, to 5%.
Airplane mode and battery saver mode makes no difference to the drain. Neither does any WiFi and GPS setting changes - I have already read about a few possible "causes".
Perhaps the only option is S-OFF and re-flash all partitions of the phone?

Running a RUU would be your best option. This will wipe the phone and restore the stock ROM (system, firmware, etc).
Have you looked at wakelocks or app usage to see if there is any unusually high usages? I had a problem with my 10 awhile back that ended up being a particular version of Google Play Services. Usually these issues can be traced to a particular app or setting, it's just a matter of knowing what to look for.

Ohio wake_lock and no deep sleep. Same issue after reflash ruu, lineage, viper... on all roms same issue and no deep sleep. I think it's hardware issue. I try to flash elementalx kernel and it fixed problem for a day, one day only. Worst phone ever for me.

How do you make a battery diagnosis?

Hi, since about a month I've been having the same issue, the kernel HVDCPD_WL and NETLINK wakelocks are keeping the CPU in use and consuming the battery charge at a rate of about 10%/hour. Has anybody got any new info on this? I read of someone that claims of having fixed it by cleaning the usb-c port, but in my case it doesn't seem to make any difference.
