Better Battery LIfe Help - Xiaomi Mi Pad 4 Questions & Answers

i have spent the last few hours looking for some info regarding battery life on the mi pad 4 and am about to just throw myself out the damn window! i keep reading about issues with the kernel and custom ROMs with no fix. some users report a 2% drop with custom ROMs while others swear MIUI is better or worse.
can anyone please give a clear answer as to what to do to conserve battery life? i currently on the latest arrowos and have a 12-20% battery loss over night and dont mind switching to a different rom.

Well I don't really use my mi pad 4 often, so basically it sits there idle. I lose around 4% per 24 hour in idle using carbon rom. Not sure which xiaomi build I used for firmware /vendor.
No battery tweaks, Bluetooth /WiFi /data always on

Well, sorry dude, I have no idea!!! Just spent ages goign through my pc files - newest xiaomi.eu rom I have is xiaomi.eu_multi_MIPAD4_8.10.25_v10-8.1.zip which has a file date of 07/11/2019, but I would assume I have flashed newer than that - vendor security patch is from 5 April 20
Latest MIUI xiaomi.eu I can see is here

I think you should try out crdroid. I've been a long time user of miui, from eu website. I tried most of the custom ones, was on bliss as daily driver before i finally settled on crdroid. It's got pretty decent battery life. The miui is very clunky in comparison and not worth the extra battery life (if any). Haven't tweaked any kernel parameters on this rom and device goes 2-3 days easy before needing a recharge. I use it mostly to read, browse, occasional video, check mail and occasional whatsapp video calls. I'm pretty satisfied with the battery

Is this battery performance normal on ICS LPQ?

Hi, I just recently flashed the LPG ICS Rom to my phone 2 days ago. I did the wipe and flashed through mobile Odin. I restored some of my apps and data with Titanium (also uninstalled most of the samsung apps)
I already did a battery recalibration (pulling the battery at 100% etc.) but I am getting pretty bad numbers. Just 7 hours tops, I guess a lot more if I dont turn on the phone but I guess this is really wrong.
Am I missing something? Should I uninstall or disable something more? This exact configuration gave me minimun 12 to 14 hours on a stock not ICS ROM.
Also I should mention that I am using Juice Defender Ultimate with connection intervals of 5 minutes, pretty average settings.
Any suggestions, tips or guesses?
Thanks a lot!
PS. I dont have any strange apps, just the normal (facebook, twitter, whatsapp, Talk...), My display brightness is set to auto.
What really matters is screen on time and you are getting barely 2 hrs and that is indeed awful but in line with all the complaints I've been seeing in the forums.
The update I got was not LPQ but rather LPE (Trinidad & Tobago) which was released the same day as LPQ. I am getting 4.5 hrs screen on time (around 15 hours with my usage habits). This is barely acceptable as I usually got 5 hours 15 min of screen on time with my stock 2.3.4.
Hopefully Samsung will fix this soon, it was supposed to be the other way (battery life improvement).
Soo...
So I guess I'll just have to wait the next rom releases, as it seems that they are improving the rom every new release? Does that make sense? the roms are being released almost one day apart from each other, arent they the same?
In case that for example a new rom comes out tomorrow and the fellows here say that it really improves battery life. What should I do? wipe and install just as this one? or would I be fine without wiping?
Thanks a lot!

Their is no normal battery usage and you have not given battery any time at all to recalibrate .
Just read the battery posts and use Better Battery Stats .
If their is a problem a full wipe is always best .
jje
Ok, so after a couple of days using it.
The battery now lasts almost 9 to 10 hours with normal use. but I deactivated Juice defender.
Now I have disabled all of google location stuff, and some of google services autosync (like google photos and reader). And will turn on juice defender to see how it goes.
Ill update my findings.
Thanks.
Ooh my holy f#, the amount of ics battery threads its too damn high

What effect do you think firmware has on battery life?

Lately my battery usage in battery monitor widget has been going over 1000ma multiple times a day. In fact this has been the case both at the beginning of my Rezound's life on the first firmware, and again now.
At one time in between I used to never see it go over at most 700ma, and experienced reasonable battery life too. Usually I saw about 70ma to 300ma usage. This was with several different roms on the same firmware. I think it was the first or second ICS firmware but I don't remember for sure.
I'm starting to think the firmware a few versions ago was better on battery life. What do you guys think?
I was running GB with the old firmware up until just last week. I was averaging about 20 hours on a full charge with 1-2 hours of screen on time. The rom ran great and the only issue I really had was my 4G would cut out completely whenever I tried to play Youtube videos....
Last week I updated to the latest official ICS global rom with the new radios and firmware, and my battery life has gone in the toilet. I'm averaging about 15 hours on a full charge with the same 1-2 hours of screen on time. My phone gets MUCH hotter when just doing simple things like browsing the web, often getting above 100* F. On GB firmware I was usually in the mid 90's unless I was gaming. This is with the stock kernel. For the past couple days I've been trying FunkyKernel with some under clocking and undervolting which has helped the heat but not so much the battery life.
I'm kinda pissed and strongly considering finally going S-OFF just so I can roll back to the old firmware.
I actually think I had the best battery life on the first ics firmware, but like I said it might have been the second one. I don't remember how many there have been, but I have done all of them.
This latest one just seems to suck down power.
Anybody else have some input?
I just recently updated to the official global firmware and am running Rezone Redux with Funky 3.7. I'm not doing any undervolting and the only change I made to the frequencies was setting the min to 96 and the max to the stock 1512. With my extended battery, I'm averaging around 4.5 hours of screen on time, which is actually about 30 minutes more than I've ever gotten out of this battery. Then again, I keep my data, WiFi, and GPS off at all times unless they're needed, screen brightness at 13%, I'm using an app called Greenify to hibernate certain apps (not freeze, there's a difference), and I'm using the Wheatley governor. I'm very happy with this setup.

So maybe it isn't affecting your as much because you keep your radios turned off. I also use greenify and it has definitely helped.
I might go a day with my mobile data enabled all day and see what happens. I got into the habit it of toggling my data off about a year ago. The only reasons for me to keep it on would be weather updates and Facebook notifications, neither of which is really important enough to me to have them refresh automatically. I don't use push email or anything like that, either. I suppose it would make a difference for someone who needed instant email notifications and such.

I also keep data off most of the time unless the phone is plugged in, but still, battery just hasn't been the same since the latest firmware update...
I want to update you guys on my battery issue I thought was related to the new firmware. Every rom I had used since the newest firmware release was horrible on battery life. Using battery monitor widget to monitor power usage, I was often seeing over 1000ma usage many times per day.
I recently installed neo's infection 2.9.1 which uses a stock kernel based off Flahalf's work. My extreme battery drain is gone! The highest usage I have seen in 2 days is around 500ma, and normally it is 100ma or less! Not only that but this Rom is smokin fast. It feels like a new phone!
And it fixed wireless tethering! I'm so happy and thankful for the awesome work or devs have been doing. Thanks guys!
Unfortunately for peeps like me who enjoy gaming on their phone, the JB roms aren't all that great. Graphics performance is generally poor....
Maybe you should give it another try. I just played some shadow gun and the performance was fine.

Then you must not have looked very hard, it is here on XDA in the Rezound Original Development forum, along with other amazing ROMs like Tron, Beanstock, Liquid Smooth, PAC-Man, etc.
[ROM][GPL][CDMA/GSM][Jb-4.2.2]☣INFECTION-2.9.1☣[07/20/13][CM-10.1.2][LINARO-4.8] will take you right to the Infection thread!
Well I thank you for the post and help I keep forgetting there are two separate forms for DEV now which i really never understood why they made two.
Thanks

Is CM responsible for battery drainage problem in Moto E?

Is CM responsible for horrible battery drainage problem like 60-80% to 0?
For investigating this I flashed cleanly CM lp based rom many times but no luck.
I turned back to CM 11 but again no luck.
Finally I flashed Carbon kitkat an AOSP rom and now the battery drainage is not like that as in CM i.e 100 -70 as normal and after that two or thee bump of 10-15% to from 70-0.
I know it may be battery issue and my moto E is 15 months old but I dont't think that in any type of branded mobile however low budget phone it is,the battery issue comes as early as in moto E.
Is it be the flashing problem as we testers flash different types of roms daily .
Then why this issue is not happening in carbon rom?
Please testers throw a light on that.
Thank you.:good:
Same query here.
Same problem here too dude..! Even I replaced with new battery...still the issue remains...
Yep...CM is responsible for the battery. If there's new features the device eats more battery....So, cm ****s battery but enhances performance and daily use.
Finally I flashed stock 5.1 optiised deodexed,lets see what's the result and I'll tell.
True, you are not the only one facing this problem.
I tried Official Cm 12.1 December build and the battery drain on standby was huge.
Now that we have official CM 13, it uses the same tree and hence the problem persists.
I am sure it is a bug but the bad part is it is not noticeable or else it would have been fixed by now.
Soltuion: Use Mokee ROM, which is official for our device and is based on AOSP instead of CM.
Note: Right now it is Lollipop and soon they will start Marshmallow nighties. I recommend using stable lollipop version.
I am using it for weeks and it has definitely the best battery life. SOT has jumped to 7 hours and the standby is also better.

Sure, try stock. I am 99% sure it is CM's problem as many people are facing the same problem.
After stock, try Mokee. It's really stable and has all the necessary features. And one more thing, the release version is odexed which means faster boot and more stability. It also has OTA updates.
Happy to help

If possible please provide the link for Mokee rom.
I have a query.
i got satisfactory battery performance when not using the phone for anything other than calling. But the battery seems to drain quick in this ROM .
I'm using the cm13 Unofficial build for condor.
The battery usage stats show computed usage and actual usage. The actual usage is double the computed usage. why is that happening?
Sry, me so NOOB.

Guys...help me...I had the same problem..so flashed stock 4.4.4..unfortunately that didn't solve battery drain problem. Even got replaced old battery with new one at the service centre..now with official stock 4.4.4 battery drain is huge..I get around 5-8 hours max. Screen is consuming around 60% of the battery even at normal usage..please please help me..
I am currently using CM 12.1 Official Nightly (latest) and I experienced a very high drain in the battery level even though the Idle time was pretty high. Can anyone help me ?

This is surely due to excessive flashing attempts. I was literally flashing five to six ROMs a day? and my battery starts to give unusual drops from 15 to 0, 25 to 0 then it started to increase, from 40 to 0 (even on stock). So I replaced the battery with a new original one and it's working great now.
I also own another condor which is also running cm 12.1 and I mostly use to clean flash a new build every one or two month, and that device is still giving a battery life like as a new one.
PS. Bought both devices on 14 may 2014.
Anyone having WiFi disconnecting during sleep issue lately on cm12.1 and 13 ?
It usullay disconnects when device is at sleep for around 30 minutes or so and reconnects on waking up. Though the setting is enabled for WiFi connection during sleep.
Hit thanks if I helped you☺

Yes, I also think excessive flashing is responsible for the battery fault and it should be not due to CM.

Me 2 having the same problem!
First it all started by a bump of 10%-0%
Than it increased ..bump of 15%-0%
Than 20%-0%
I tried many ROMs still had the same problem! ..I read somewhere at XDA that lithium ion doesn't need full charge and overnight charging is harmful.. And can cause bumps ..
So I charged my battery to 75% and than I didn't got any bump ..as I tested till 3%..
So what I suggest is..those who are facing large battery bumps, do not charge overnight and charge till 80% and check ..
Yesterday I replaced my battery with the new one.
And no issues facing so far.
I think excessive flashing harms the battery.

Battery backup

Hi guys,
I've a problem and I need some advice.
I've a Kenzo since last October and it's a great phone. I've always used the miui since last month then I've tried some customs ROMs.
My problem is that, with the miui my battery usage was 10% each sot hour and for this reason I could easily reach 8-10 hours sot. The main reason was that I use my phone only for WhatsApp, sync disable, battery saver GPS, no 4g connection and auto brightness disabled.
Last month I read a lot of forums and I read that you could reach ROM the same (or more) sot hours using a custom instead of the miui.
So, for this reason and because I'd like to customise more my phone I decided to flash a custom ROM.
In this last period I've tried ROMs like RR, Nos and lineage os, each in stable and beta version and I combined it also with some stock kernel like Agni and radon. I've always flashed them wiping everything (cache, data, system, internal storage). I also cleared battery stats with Agni toolbox
My problem now is that, with the same usage I used with miui, my battery drains 18% each sot hour. That means that my battery now drains twice faster with the miui.
I don't think that it could be a problem of the battery deterioration: I always pay attention to charge it when it's among 20-40% until it 100%.
My purpose is to reach the same miui battery backup with a custom ROM (I love the possibility to costumize and I'd like to have recent Google os).
In your opinion, it could be possible?
Thanks a lot!!!!
I only have 5-7h sot with latest RR. For me the battery backup at MIUI was better.... But I hate MIUI so far.

Horrible battery life

Hey, I have a redmi note 4 snapdragon version and I have flashed aosp extended rom and franco kernel in it, but I am getting a very poor battery life, hardly 1 hour screen on time and the phone shuts off by the time battery gets to 30 to 20%. My phone is rooted too and i am not using any kind of battery saver app.

I think this is an hardware issue but, I am no expert so please help me on this and let me know what should i do. Thank you.

The problem started probably when i rooted my phone on stock rom(miui 10), the very next day i cleaned every thing (including my firmware accidentally) to flash custom rom, then after flashing i found out that none of the hardware components are working and i posted a thread about it and as per the answers i flashed a latest chinese firmware for redmi note 4.And it worked except i started noticing an awfully bad battery backup(hadn't noticed before as all this happened in just 2 days. (as a matter of fact the battery went down 5% as i wrote this, oh 6 now!)

Cleaning everything, as you stated, including the whole firmware,
You answered your whole thread yourself, just flash stock frimware, then flash AEX like flashing any normal ROM.
I have the same problem, the battery die after 1h screen, when the battery Is on 20% the device shutdown,help me pls, i have rr with franco kernel.
hi OP. base on what you are describing, it looks like your battery is dying... nothing to do with the OS. be careful 'cause chinese batterys (like 70%) turn out to be real sh*t (on my own experiance). consider to replace battery from a confiable retailer or change device.
