Battery Optimisation - Xiaomi Redmi Note 4 Questions & Answers

I don't know why but the android system is always high instead of the screen. And I see people getting 12hrs of Screen on time where I am only getting hardly 7hours. :/ I tried many roms, but all seems to have the same problem :3

The battery life is usage dependent, as well as statistics. You need to figure out what is causing the battery drain in your case. Check what functions of Android System are using the battery and check what apps are using those functions.

7hrs sot is normal.

From what battery level to what battery level you analysed to have 7hrs sot..?
I am on stock miui 9 and i get 6hrs sot at 50% battery left. And 9:30hrs sot at 20% battery left.
I don't go beyond this battery level, prefer to charge back to 100%. I had similar result on stock Miui 8.5.

try flash AOSP-CAF bro with its default kernel,, i got >24hrs of total battery use and >9hrs SOT,, plus this ROM is smoother than Miui9.. Thanks me later

if you use your phone for 2 or 3 days, 7 hours is normal buddy... becasuse the standby consumes battery too...
if you use it non-stop, you will get 12hours of SoT...

ATT version of SG2 sucks your battery?! *Fixed*

Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

Used Nexus S, LG Thrill, Samsung Focus, Infuse, This is the best Android phone for battery. I have 40% left with normal use (emails, calls, music, read news) at the end of the day. Huraaaaa

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.
Sent from my SAMSUNG-SGH-I777 using xda premium
I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?
Install this app:

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!

[Q] normal battery drain rate for CM7.2?

I got a battery app installed which shows % in the top bar. It stays at 100% for a while but when it starts draining with the screen on I lose about 1% every 1-2 minutes, I think its somewhere in between, if I am taxing the cpu it more frequeent than every minute, this would give me about 2-3 hours usage which seems extremely low.
Brightness is min.
wifi/3g off.
auto sync off.
accuweather is installed (mentioned as it has a service running).
I get the drain simpley from doing things like scrolloing app drawer and checking sms.
With screen off in sleep mode battery drain is ok less than 5% in 12 hours. I have this issue confirmed on 2 different batteries.
If this is normal fine, I just want to compare to others on this.
I used to get around 1 day for heavy use ( like wifi, games, etc.) and 1.5 to 2 days for moderate use Which ROM are you using ??
Cm7 based roms use more battery than stock, cuz also their performance is a lot better.
Use uot Kitchen to get the % battery instead of an app.
Also the launcher u use affects battery. ie Go launcher drains plenty of battery.
If you can't squeeze a day's worth of battery from ur phone ur probably using it too much (how much does a laptop last on battery, seriously!)

you mean a day of constant use screen on or would there be periods of it sleeping?
My phone lasts more than a day mostly 3-5 days but thats mainly because its idle most of the time. However I plan to transfer some tasks to it and it seems I will need to keep the charger in during the day.
Compared to stock CM I think isnt too bad, the drain was also bad on stock with the screen on and during calls but the only reason I specified CM is that I didnt have the % meter on my stock rom which means I dont have the same comparison.
My current rom is vo-1's 30 may build. I had bugs on official nightly that vo-1's resolved (including force reboot when using market) so is the reason I am using it.
Incidently my laptop drains its battery slower than my android.
Why I read that so many use thier phones like 2 days, and I can't even get a 12 hours fair use.
I use 2G (3g drains my battery really quick), some whatsapp, some FB and some calls. Music it's only in the morning on my way to work.
I've buy a new battery from ebay, but, it's the same. Using CM 7.1 rom "The End 4.0"
yeah my hunch seems right that it wasnt overall much diff to stock (that also drained superfast when screen on). IN fact during sleep it seems improved over stock.
I am over 4 days at the moment with 35% charge left. mostly sleep. It lost 3% during the time it took me to fetch the below stats. Note that calls like my earlier hunch as well seem to drain battery far more than display.
4 days 8 hours 38% left
display on 40mins used 4%
voice calls on 1hr 5mins used 33%
mobile standby 41% 4hrs 8 mins
phone idle 4days 7hrs 23%

Surely, you're not using WhatsApp, Facebook Messenger, handling e-mails or any of the like. If you're just using the SGA like a normal phone, OF COURSE it can give you that kind of performance. If I'm wrong, please correct me.

He barely touched his phone Anyone can get 5-6 days like that! And being on Stock, it's extremely probable.
Well mate you can't expect battery on a cm rom. Performance and good battery isn't an option on cm. Performance is great on cm but battery, nah!

yeah sadly it seems noone has a comparison that I need.
Which is time needed for 1% usage whilst screen is on.
This isnt on stock tho the phone is on CM7.2 vo-1 build.
From what I see the battery life is around the same as stock.
Now I am over 5 days with 17% left. Just did a phone call and it stayed at 17%. When below 20% on stock the phone was unuseable.

battery drain

I have a huge battery drain issue. 12 hour battery life with 40 minute sot. I think it is because i did a complete wipe and then installed a custom rom. That rom gave bad battery so installed another and another.. Trying to figure out how to wipe everything and then go to stock and what is stock rom? So many versions out there. Can someone please help? I have twrp installed. Thanks!
Unfortunately, 12 hours regular use is good.
The problem is small battery size + 2K resolution screen. Look forward to Max 3. Hope it has better low energy consumption screen and bigger battery.
Battery will finish quickly if you keep the screen on.
i used to get lot better. with 40 minutes of use 12 hours is not good at all. I used to get 24 hours with 4 hours of sot
I performed tests on various EUI based ROMs and playing 1h of full HD movie on medium screen brightness take about 18% of battery assuming WiFi and cellular data is off. It takes about 21% if Bluetooth earphones are used.
My advice is to perform another full wipe and install eg Madsurfers ROM which I run successfully with good battery performance especially in idle about 12h on about 5% with WiFi on.
If I help you please express it.

Battery Drainage

after update of MIUI 9.6.18 is battery draining faster or I am only feeling this thing?
Yes, I feel the same. I'm barely getting just around 5 hours SOT on normal usage without gaming.
I don't think its true in my case, just today i drained it to 5% and sot was 7.5 hrs which included pubg 2 hrs, world of tanks 30mins, utube 1.5 hrs and other normal usage like twitter, little skype about 45 mins. sorry i don't hav the screenshot to show
I get 8hrs of sot.. I tried every thing to get drain faster but it doesn't drain..

Android 11 Battery drain discussion

Hey folks, see if this is the right forum to post this.
Like some other people on here and on reddit the latest Android 11 update C.57 caused a lot more battery drain on my device.
Before on A.46 my over night drain was about 2% which is good I think with Wifi on.
With Coloros 11 it can be over 10% drain over the course of 6-8 hours which is far more.
I have tried gather info from my phone which app is draining but it looks rather normal.
Even tried the adb command to force the phone get the phone to do the battery optimazation manually without luck, seems I have dont have the permission to make suchs commands through ADB with USB-debugging mode enabled..
However this morning I found in Settings>Battery>More Battery Settings>Optimize Battery Use
The whole list on every app there was set to "Always ask" and not "Optimize Automatically"
Now I changed every app to Optimize Automatically and will see how this affects the current drain.
I read somewhere that to the phone to get to this "state of battery optimazation" you need to have the phone in the right state to execute that which was Battery Full on Charger in idle mode not moving for a few hours.
So I thought if the battery optimazation settings where set to "always ask" (which it never did) this state maybe never happens?
Anyways feel free to share your battery settings and what Battery standby drains you guys got because I have been going a little nuts over this issue haha.
I wouldn't bother changing the battery optimisation settings, they seem to reset themselves.
I wasn't getting great battery life so finally did a factory reset. After a week the battery settled down and is now ok, probably around 5.5 hours screen time a day at qhd 120hz with always on display in from 8am to 11pm. I don't really check battery drain overnight, I will check it and report back.

Yes I checked them again now after you mentioned it and they do seem to reset. However now my phone seems to work how it should, currently 3 hour screen on and 64% battery left. Wifi at home all day. Also the standy drain is night and day better now. Maybe this was a bug in Android 11 that kept it from optimize the apps?
I have adaptive on both refresh and resolution and same Always on time settings as you.

Glad it's working better now. I do find the battery a bit inconsistent, some days it's great and others it goes down quickly. I've turned location off now as dont need it that much, I lost 3% overnight which seems good to me.
I really don't understand how you guys get such a low battery drain overnight.
On ColorOS 7 I had 10-12% drain overnight.
On ColorOS 11 it stayed the same. I have reset my phone, now it's about 7-8%.
This is with night optimization on in the settings. 5G disabled.
I always was able to get that 3% on my older OP 7 Pro. Even on my Realme X2 Pro, which had the same OS!
Also, my SOT is not that good. On mixed data/wifi I only usually get 3.5hrs SOT. After the reset its 4hrs now.
With 5G on it's unusable, even with good coverage here. (AccuBattery: 6hrs SOT, 57hrs standby, just very bad)
It's nice to have Dual SIM now with Singapore EX, but I cant use it, my battery just can't handle that.
I kept this phone just because the rest is awesome, but the battery is such a letdown.
I thought it was a SD865 problem, but I also had the Mi 10 and Poco F2 Pro as a secondary device without any drain problems.

However I had a big drain again over night so gonna try to set apps to optimize again.

Yes I agree the battery drain is very weird with this OS.
Have you tried changing the settings in the battery optimize section? I turned on optimize automatically and then charged my phone full and let it sit for a while with charger plugged.
Try this and see if it gets better.
Its weird that the settings change after a while tho.
Just recently managed to use the phone and have to confirm ColorOS 11 is killing battery overnight, I have this for few weeks now so should be all optimised, yet still overnight is around 25-30% battery gone, my previous mate 20 pro was taking maybe 2-3% overnight so is massive hit. No notification is allowed, do not disturb on with wifi and mobile off, really weird is behave like something in the background was still on.
mine only about few percent but my battery life sucks at 4-5 hour ish
