Hey all, I don't know if anyone has even noticed on their Evo's but on mine, the Android system usually eats most of the battery. I noticed there is a ton of processes under Android system that are running compared to like five on my Hero. I've never seen the core system processes take up more than maybe 15% of the battery, but right now, I'm at like 41% with 16m 6s of CPU total and 47s of CPU foreground. If anyone knows why this is or a way to fix it, please let me know. I'm on the first MR update. I've been able to get a lot of battery stuff figured out, if I can get the system to calm down, then I should be able to get even better battery life than my Hero.
I'm seeing the same thing, android system is at 96% battery use after letting the phone sit overnight. Never saw that on my nexus, this is strange.
Could be related to the fact that everything is syncing up, I just activated last night too.

Yeah, the system seems to have calmed down a bit today, though I also have the OC widget running to keep the processor lower during sleep. I'm guessing its helping, but I'm not sure if there is something else to get it down. I almost never even saw the System show up in usage on my Hero, now its one of the top contributers. I got used to having custom roms on the Hero, but so far all I need on the Evo is unrevoked. I know a lot of people around here don't like it, but I found I only needed a couple of apps that require root and so far love it. That OC widget really comes in handy.
maybe i can clear things up a little bit for you guys...what you see in the battery use section is distributed across 100% of the time since you last had it plugged in. if you notice all the percentage numbers add up to 100%.
if you plug your phone in and turn it on and off on you will see that android system is probably around the 90's thats because android system has used 90+ percent of the phone since you plugged it in....over time that number will lower, becuase other things will start using the battery power... what you see is a percentage based on time. not based on whats actually working RIGHT THEN AND THERE do you guys understand?
I too am having that problem and at 15% battery life warning - it still shows my Android system @ 40-44% usage after 8hrs of work.
I mostly text message all day long due to work - make phone calls and recieve calls from work every hour. GPS on for no more than 15min all day long to get direction when my keymap book doesnt help.
4g off, bluetooth off, background data 15 min only (gps) than off, gps off when not in use, mobile network (3g) off when not in use.
I would have figured my screen being on would have drained my battery life since I check text message every 10-15mins for 8hrs...
So went to work at 9am, 100% life
got off work 6pm, 25% life
I've done all the tricks, cdma only, force stopped a bunch of apps, goggle talk off, sync off, making sure maps/gps has been closed (forced or not)
still disappointed with battery life.

check your hardware version there is a thread about different types of evos and it seems like everyone who has the hardware revision 0001 has really bad battery life. i would exchange your device.
Yes we know, Freelancerx, or at least I do. But after over 8 hours and the system is still using more of the battery than anything else is a little disturbing. Never seen that on any other device. I have Hardware 0002.
I have this same issue with hardware version 0002. I run Fresh 1.0.1, i use Netarchy-toastmod kernal, have latest radio. I have also tried Damage Control (did get slightly better battery life out of DC but not amazingly different)
after 7 hrs since unplugged my andriod system is at 39%, cell standby 28% phone idle 20% display 9%.
i dont have bluetooth, wifi or 4g on. I use juicedefender+ultimate to turn off apn when screen is not on. I use set CPU to underclock when i am unplugged and go down to 128 when screen off and i am Stilll lucky if i make it all day with moderate usage.
Every day it is the same andrioid system is around 40% of the usage for the time it was unpluged.
the following is listed under included packages (not sure if this shows the same for everyone or if it shows what packages are running)
BRCMBluetoothService - Bluetooth is not on so if it shows packages running this may be an issue
Sync Feeds - I have all android syncs off and mail at 6 hours
settings storage
Rosie Utility
Acounts & syync
Account and sync settings
settings
HTC Widget Download Manager
Network Location
Setup
HTC Checkin service
Checkin serivce
VPN services
Android system
Wonder if there is something to the android system on these (ie something not turning off that should) or if we are all just crazy and happen to get the same results.
I had a hardware 0002 model and often experienced the same thing with high system % usage.
My phone was replaced, due to a screen issue, and now I have the 0003 model and seems system % is much lower so far.
I haven't installed any system update yet, so I am on the first original release rom (not rooted yet).
Going to be testing it for a few days before I update and root, so I can make a fair comparison between the original and current oem's.

I think everyone here understands this. the question i think we are trying to figure out is why with similar usage and configurations some people get 40-60% android systems usage while others get 10% over the same period of time.
Android system is way too high.

Yes but if it is configured in an optimal way then android system is always beneath cell standby and phone idle.
For example, today after 15h 28m 23s since unplugged I have...
Cell stanby 38%
Phone idle 37%
Android System.....12%
That is with background processing with auto syncing every hour or so.
I just got a new desire after my previous one got stolen.
I found out the battery of my new handset last dramatically less than the previous one...it doesn't even last one day!
I reduced the screen brightness to 20% and deactivated the 3g mobile data but on the battery screen usage it says as follows:
cell standby 31%
phone idle 30%
android system 23%
display 7%
voice calls 5%
internet 2%
dialer 2%
why would the usage be so high when the phone is in standby? why would it be so high for the phone idle?
I also found out it takes ages to shut down completely...is there anything running underneath that I can stop?
please advice the optimization setting to try to improve battery life please
thanks in advance
The percentages just express which parts of the battery drain (lets say you are on 68% --> 32% drained) have been used by which activity of the phone (so they are not absolute but relativ values).
In a combination of your and my example this would mean.
30% cell standby --> 30% of 32% is at least only 1/9th of the whole battery.
Hope you get what i am trying to explain
I see where you come from but I don't think this can explain why I need to charge it every 5 hours.
Have you calibrated it,?? Search battery calibration, and try that.
Is your phone rooted michaelss16???
no my phone is not rooted but I think I managed to sort it out!
set it up as follows:
MENU> settings>wireless and network>wi-fi seettings>menu>advanced> wi-fi sleep policy> after 15 minutes
MENU> settings> sound and display>brightness> uncheck automatic brightness> reduce brightness manually by sliding it down to no more than 30%
MENU> settings> sound and display>screen timeout> set it no more than 1 minute
MENU>settings>account and sync>uncheck background data (it is possible to check it manually by refreshing it everytime is needed)
MENU>settings> Location> uncheck both "use wireless networks" and " use GPS satellites"
MENU> friendstream>menu>settings>Accounts and sync>for any of your active accounts(facebook, flickr, twitter) go to account settings>update schedule>set it up not more often than every 4 hours. (you can update it manually anytime you want)
MENU>Latitude>menu>privacy>turn off latitude. (it is possible to turn it on when maps app is needed...don't need it on all the time)
MENU>Stocks>menu>advanced>uncheck auto-sync data (you can refresh as needed)
MENU>weather>menu>settings>uncheck update automatically (agai nit is possible to update it manually by hitting refresh button)
In addition when in charge at night I shut mobile network off (I don't check updates-mail or post if I sleep)
Since I don't expect any phone call at night I turned the radio off by dialing *#*#4636#*#* >phone information>turn off radio (don't do it if a phone call is expected).
it is also possible to access battery history to check through all the processes running on the background and using power,CPU memory and bandwidth. ( the menu settings battery information refer only to the TIME of each process draining the battery and not the amount of battery drained by each process).
Now I understand why phone idle and standby was so high when checked in the morning..they are the only processes running at night when the phone is in charge if it is on).
Hope it can be usefull ....now it says 14h 52m and 13s since unplugged and battery level is still 54!

Basically you just did what I always recommended you, update manually all the applications, except for the radio, I just turn off the mobile data so I can still receive calls...
Battery drain and overclocking
I rooted my phone and installed Runnymede AIO v6.0.4.1. After installing i guess a default value has been set for the OCD as around 996000. I later changed it to the highest value and played a game. with in minutes my battery drained to 30% from 70%.
I mainly rooted my phone so that the memory constraint in HTC Desire can be done with so that i could install more and more apps and games.
I NEED TO PLAY GAMES and WHAT WOULD BE THE BEST VALUE to keep FOR OCD, so that my phone is fast and i could play games without even a minor lag.
And i also have another problem, in call history i dont see names against the calls made. However i can see those people in my contact list with names and numbers, but in call history i see only numbers and a + sign asking me to save to contacts.........
Can anyone help??

Does the "new thread" button not work for you? Hijackers should be prosecuted
For long time I was using Starburst ROM (stock + D2SD on SNQ kernel). It was really good in performance and battery saving due to basic Sense 2.2. I could play AngryBirds couple hours long. The major factor was screen brightness to be dimmed a bit. Since I dropped gaming behavior I had no experience with other ROMs/kernels I was trying.
-andy.
Well, I searched the forums and haven't found anything specifically for the Defy.
Coming from an HTC Wildfire, which under similar usage had a battery drain split of 30% Cell standby, 30% wifi, 30% system, I noticed that with the exact same usage, the Defy has a cell standby use of over 50% every single day (right now its at 54%). Funny thing is, it ALWAYS says on the battery manager that there is no reception for exactly 50% of the time. This is bull, because I live in central London, and I rarely get less than maximum signal displayed.
Also, I'm on WiFi almost all the time, (WiFi at home and at uni, so the only time it uses 3g/HSPA is on the way there and back, which is less than half an hour).
Has anyone else had this? Any idea what may cause it? I feel like I should be getting better battery life than what I'm getting now, it lasts under a day.
Setting your mobile to 2G only should save you a little power, also be careful with task killers as they can kill some system processes that reduce battery usage, restart you cell to get them back.
I can get 3-4days of battery life with lite use.

Thanks for the reply.
I'm not using any task killers, so that shouldn't be a problem.
Any tips on how to switch it to 2G? I can't figure out anything in the network settings.
I'm just thinking that there may be something wrong with my radio receiver/transmitter to be using so much power in comparison to wifi and phone idle (well, compared to my last phone).
You can switch to 2G in wireless & network settings, mobile networks, select network.
But I am already using 2G and I have the same issue, maybe it is a little better than 3G, but still the "cell standby" is using most of the battery.
I saw the battery usage on Galaxy and there is only a very small usage for "cell standby" only about 10%.
i dont know what's going on with your cell,but WIFI is actually the biggest battery taker
,and the strength of signal power really do something to your WIFI chipset battery usage
what about a better WIFI signal....err i tried to change my cell into 2G or even outline
it doesn't work too much as i want
so maybe think about the WIFI problem?
Well, right now the main drainers are as follows:
Mobile standby: 44%
Go Launcher EX: 25%
Wi-Fi: 15%
Display: 15%
Phone idle: 2%
I was in my place all day today, with the phone permanently connected to Wi-Fi, so 3G was not in use. I get very strong cell reception in my place so I either have a spectacularly efficient WiFi module, or a power hungry cell radio. Or the measurements the phone is taking are wrong.
On another note, Go Launcher seems to be taking up a large percentage since its last update (yesterday or the day before), so I'm uninstalling that.
if WIFI should not be the reason and you've uninstalled the update task,i think it should be OK...but what would you do if that doesn't work?
the battery usage of standby was still more than 40 percent,yes?
why dont you download another battery monitor software....?
i'd have a longtime software error in my HTC G3.....it alwaws show me 45percent remaining battery ....
in setting/wireless & network/mobile networks/select network --- it's good to set 2G or 3G do not let automatic because it switches from 3G to 2G if the signal drops. Set 3g and see how it is.
(sorry for english)
mine on automatic in 6 hours battery dropped to 50% in standby, and now it is set to 3g all the time
mine:
Mobile standby: 40%
Display: 22%
Phone idle: 21%
System: 4%
Games, Adw Launcher EX and os: each 3-2%
when in games mine sometimes freezes and i must get out and restart the game???? i dont no why and i dont no if it is ok but ....
Thanks for the input everybody. So all of today I used the phone pretty sparingly at home, and it's been constantly connected to WiFi. Distribution is:
Mobile Standby: 56%
Wi-Fi: 19%
Display: 12%
Phone idle: 9%
Android System 2%
Under Mobile Standby, it still says "Time without a signal: 50%" even though it's definitely had perfect reception all day. I don't know what's causing it to report incorrect numbers :/
Anyway, I switched from auto to 3g auto (I tried 2G, it didn't seem to work properly, Google wouldn't even load).
I guess I'll just ignore it :/
Edit: When not on wifi, it seems to switch between 3g and HSPA quite often. Could this mean something?

just like what <stapuv>says when your cell drops any one of the 3G or HSPA singnal another singnal will be switched...it'll use more power for changing network frequently.....but i dont no if this could be the reason for your situation...hmmmm
From my reading the 50% without signal is just a software bug, and can be fixed by toggling on aeroplane mode turning of teh screen for 20 seconds or so and then turning of aeroplane mod when you notice it's happening. the 50% will soon decrease. I too believe that cell standby is using way to much on my phone (always 45%+) even though im browesing the web facebook or playing games for larger peroids of time and those apps don't even show up on the battery usage display and if they do theya re only 2 percent or less.
I have a question for you guys :
I get
46% mobile standby
43% phone idle
10% voice calls
3% display
is this 43% phone idle all right? Doea it mean that 43% of the battery have beed drained by phone in idle state (so maybe not sleeping?) or it means that from all the time phone was idle (asleep) for 43%?
I guess mobile standby use is about the same on everyones phones. That's what I wanted to find out!

After Go Launcher EX latest update, the battery seems to drain a lot faster during idle/standby. Removed that and standby battery usage is better.
Just thought I'd add my finding on this.
My Defy regularly showed Mobile Standard over 50% - but also time without signal was always double the time that the phone had been switched on. For instance if the phone was switched on since a reboot for 1 hour then mobile standby would show the total time as 2 hours but time without a signal as 1 hour.
I had always been running on a battery saver profile (in froyo I was running the custom battery profile) & after every reboot the mobile standby bug would show.
Yesterday I changed my battery profile to the Performance mode & after several reboots the bug hasn't shown up & now the mobile standby shows the total time correctly & zero minutes without signal. The %age use has dropped to be more in line with wifi at around 32%.
I haven't noticed any difference in battery life so as mentioned in a previous post it does look like some sort of bug.
A percentage is a proportion.
Just because it's higher on the Defy, that doesn't mean the mobile standby is using more power than it does on other handsets, it could just mean everything else is using less.
There's no point comparing your Defy's battery usage to any other handset apart from another Defy.

OK so after a few days of having no issue I rebooted the phone & the "bug" came back today so I guess it wasn't to do with the battery mode as I then put it back into custom battery mode, rebooted the bug went away.
Haven't noticed any difference over the last few days so I'm not going to worry about it.
I have found that DEFY is getting the readings wrong!
Here is how I get this:
1) fully charged the battery
2) started angry birds.
3) ~2 hour later, battery dropped to 60% and usages was as follows:
mobile standby 49%
phone idle 40%
display 4%
angry birds 7%
WTF ?!?! it should be : angry birds ~ 80%
This mettery is tottaly useless!
Personally I couldn't care less what the battery usage breakdown says. In my case 1% battery can standby 1~2 hours or use 3~5 minutes. That's pretty good for me as a charge can last 2 days.
Hi.
Could someone with this "bug" or "battery problems" do a test for me ?
A few hours after you've last charged your phone (or connected to USB) and being sure you haven't rebooted your phone recently (24 hours or so), do the following:
(My phone uses spanish language so the names might be different ...)
Dial *#*#4636#*#*, and choose battery history.
There, choose "CPU Use" and "since last charged".
What are the 4 or 5 main processes appearing in that list, and what's the CPU time they've used (you'll find that by "clicking" on the process' name) ?
Hi all fellow forum members! It was about time to retire my old Galaxy S2, and i decided to buy a S4 Mini. About the same size, better specs and everything. But i dont like the battery life at all. I dont think its normal for my battery to discharge 20% over 8 hours at night. Does anyone have the same problem? I have been trying different approaches. I installed Snapdragon BatteryGuru, put the phone on power saving mode all the time, even switched 3G off, although without 3G there seems to be an improvement, but I'll let you know how's that going. So my concern is that i might have a faulty device.. or software.. idk.. when i had crazy discharge syndrome on my S2 i just changed the kernel and/or the ROM. Any advice or opinions on the battery life of the S4 mini will be welcomed and appreciated!
I don't have too many battery problems, I guess. My phone has been off the charger for around 10 hours - and the battery has dropped to 85% - which I think it OK. I've sent some text messages, checked e-mails, used WhatsApp and had a few phone calls, not exceeding 10 minutes in total. Oh, and the GPS is on 24/7 for now, but I've just got the phone rooted, so this will not be the case any longer. The phone says it still have some 7½ hours left - which wouldn't be enough for an "all nighter" tonight.
I have disables many of the push notifications, which might be the reason why I think it's a fair battery life so far. I used to have the SGS2 as well, which lasted around the same as this phone I reckon. The biggest hog is the Google Services/Framework that takaroundes up 25% of the battery usage at the moment.
I have though of having getting an extra battery for this phone, as it's always nice to have one charged.
My I9195 uses about 3% during night (7 hours, 3G data and wifi off). Try to use an app to see wakelocks used on your device, e.g. Wakelock Detector or Better Battery Stats - they might provide you with some hints to apps that keep your mini from deep sleep, which can cause the battery drain.
Sent from my GT-I9195 using Tapatalk 4 Beta
If it's an I9195, can you try to disable NFC and see if it improves?
My biggest drain is the screen. The device lasts about as long as my friend's S2 (we were playing a coop game together) and then surfed the net over 3G for a while.
We both scrambled to look for a nearby charging socket at almost the same time
Thanks for your replies guys! I will try those apps and report back. Wakelock already found one of my apps that has awaken the phone 1200 times.. shieeeeeeeet.. hopefully now that I have disabled it things will go better..
Hi all! I have found the source of my battery drain. It's Google location services. Turns out it's a common problem on android 4.2.2. I tutned off Google location an I my phone drained 2% over 8 hours. Sync, wifi and 3g were also turned on. There is a fix over at the nexus 4 forums, but it requires root and I don't know if it will work on our galaxies. If you have root, google nip wakelock fix, try it and report back.
I had battery problems on my s4. Turns out it was the SD card. Removed it and battery improved. In the end I had to change it for a new one.

Which one did you use? Sandisk 32GB?
I got an S4 mini for my gf with that card and it has terrible battery life.
The battery drained from 100% at 7 in the morning to 15% at 5 in the afternoon...
That's surely not normal...
Edit:
I noticed that the "media" service took up almost as much cpu time and power as (active for 1,5 hours) as the mobile connection.
I suspect, that some corrupt media files or whatever kept the service alive, which tried to scan the DCIM folder over and over again.
I checked the SD Card which was full of almost 5GB of old pictures pictures which for some reason couldn't be deleted because of "unknown errors".
So I took the SD Card out and put it in a card reader, to back up the files. Then I deleted the files, put the card back and formated the card.
Then I copied only some of the new pictures back into the DCIM folder... I'll see tomorrow if that helped.
Battery Drain
Hi iconata,
Can you let me know how to "disable" Google location services, which you observed as the source of battery drain? I believe I have disabled it but the battery drain issue still persists.
And FYI - the following is the message I wrote to Samsung and am waiting for their test to validate the result of my S4 Mini. Based on what Samsung told me, the Safe Mode calls out same phone settings as Factory Default, but it seems the following test cases did reveal different resutls from what Samsung told me...
Message to Samsung
-----------------------------------
Hi,
Thanks for advising to check battery under Safe Mode. The following is the 3 test cases I have done but I still have BIG battery drain issue with my S4 Mini.
All the test cases were performed under same conditions:
1. 3G on
2. Power Save Mode on
3. Standby for 8 hours overnight, from 12:00am ~ 8:00am
Test Case-1: All the extra apps installed
- Battery drain: 3% per hour (as I already reported)
Test Case-2: Safe Mode; long press volume-down key, with Safe Mode shown at lower-left corner on desktop
- Battery drain: 0.7% per hour
Test Case-3: Factory default settings; reset to Factory Default setting; all the data were deleted and no extra apps were installed; the phone was back to the original Factory default setting
- Battery drain: 2.9% per hour
Test Case-1 and Test Case-3 almost came with same battery drain issue at same drop rate, so those extra apps installed for Test Case-1 shouldn’t have contributed to this battery drain issue so significantly. However, looks like Safe Mode and Factory Default were very different, although you thought the conditions of the 2 should be same.
I still have battery drain issue even after rolling back to Factory Default Settings, and I cannot live with Safe Mode. Please help.

And FYI - the following is the message I wrote to Samsung and am waiting for their test to validate the result of my S4 Mini. Based on what Samsung told me, the Safe Mode calls out same phone settings as Factory Default, but it seems the following test cases did reveal different resutls from what Samsung told me...
Message to Samsung
-----------------------------------
Hi,
Thanks for advising to check battery under Safe Mode. The following is the 3 test cases I have done but I still have BIG battery drain issue with my S4 Mini.
All the test cases were performed under same conditions:
1. 3G on
2. Power Save Mode on
3. Standby for 8 hours overnight, from 12:00am ~ 8:00am
Test Case-1: All the extra apps installed
- Battery drain: 3% per hour (as I already reported)
Test Case-2: Safe Mode; long press volume-down key, with Safe Mode shown at lower-left corner on desktop
- Battery drain: 0.7% per hour
Test Case-3: Factory default settings; reset to Factory Default setting; all the data were deleted and no extra apps were installed; the phone was back to the original Factory default setting
- Battery drain: 2.9% per hour
Test Case-1 and Test Case-3 almost came with same battery drain issue at same drop rate, so those extra apps installed for Test Case-1 shouldn’t have contributed to this battery drain issue so significantly. However, looks like Safe Mode and Factory Default were very different, although you thought the conditions of the 2 should be same.
I still have battery drain issue even after rolling back to Factory Default Settings, and I cannot live with Safe Mode. Please help.

Hi pudin! You can turn off Google location services from maps app. Go to settings->google location settings and uncheck allow Google to use your location. And to further improve that you can turn gps off, and turn it on when you need to. Yesterday I decided to root my phone because greenify was asking for root permission and everybody was putting the good word for that app. Turns out it's a total croc... you can hibernate downloaded apps, but you can't do the same with pre installed. 0 use. Further more I started to receive an annoying notification that my phone's security has been compromised and it needs to reboot. Got angry, downloaded an official firmware from sammobile, preinstalled, turned google location services off and got this pretty decent battery life. Screenies are below, feel free to post your thoughts. Please note that I keep BaterryGuru and PowerSave on at all time.
Battery drain
Thanks for prompt feedback iconata! Now I can confirm the Google location services have been disabled on my S4 Mini. Also, I don't enable GPS unless I need it so those battery consumption numbers were tested without GPS running in the background. I got the call from Ssmaung tonight telling me my phone consumes more power than what they tested, so I'll return it to Samsung for further diagnostic tomorrow. Will keep you posted if any update.
BTW, I'm not that kind of guy brave enough to root my phone like you guys...
im having 3% battery drain over night

ill repeat the test today from 100% battery and see
battery drain during standby
Hi,
Checked the image you posted and it looks like you were still doing something such as making calls and playing game over night. Your 3% power consumption per hour is similar to mine, but in my case Cell Standby and Device Idle are the 2 major items consuming the power the most over night, when the phone really enters the standby mode. Try to have your phone enter the standby mode without doing anything over night and check if the result is still the same.
strange thing... my battery was showing 16% left.. and went dead..

New FW update that improves battery drain
In coincidence I got notified of a FW update just yesterday night, one day before I sent my phone into Service, and it did improve battery drain significantly, from 3% to just 1% per hour over night after I checked the phone this morning. You guys may want to check the update as well, and I'll test my phone again tonight.

Which firmware?
I flashed the pre-rooted MG4 (over the stock MG4) yesterday, wiped the phone and froze all the samsung bloatware stuff.
That thing is still draining about 4-6% per hour while just lying around untouched. The phone is in power saving mode.
new test factory reset, all bloatware removed, just whatsapp is installed

I still have 1.7% battery drain per hour I think is still bad
GMS arena seems to be the only site mentioning that issue:
Unfortunately the higher than average battery drain in stand-by mode prevented the Samsung Galaxy S4 mini from getting an impressive overall endurance rating. Even so it did more than well and if Samsung improves the stand-by time with future firmware updates, it might be one of the longest-lasting smartphones on the market.

Hello guys, yesterday I noticed an huge battery drain on my RN8.
The phone is new (received it on 18 December). I state that when I use it I always have 4G on (because right now I'm without wifi connection at home, damn my ISP) but of course sometimes when I don't use the phone I turn it off. I stay with GPS off, Google Assistant off, and still I notice a battery loss of around 3% every 45 mins, even when the phone is in standby, every 10-15 mins when in use (too much!)
And, as I use WhatsApp, I recently noticed that it is lirerally eating my battery, you'll see on screenshots.
For the charge, I always try to keep the phone from 30/40% to 80%.
What can I do? Are there some settings to improve? Maybe a way to manage apps working in background? I don't always want to stay on Energy Saving mode, or is it the only way?
oh that is a huge amount of battery drain, the Facebook app used to do that some years ago, and the advised solution in whatsapp make a backup of you data first, then go in to; settings, apps, and clear cache and data for the app. could also try reinstalling the app.
as you dont have a internet connection at home but you still have wifi, you phone/whatsapp might be trying to make backup but it can't cause of no internet. try change the settings in whatsapp to back over cellular aswell.

Hello buddy and thanks for the reply.
I haven't noticed any backup settings on: however I followed your tip and tried to reinstall WhatsApp, seems that now consumes are normal. I also tried to go on Settings -> Battery and performance -> Power save app -> selected WhatsApp and selected "limit activity in background" so maybe this is also doing its work. I know that I won't receive notifications if phone stays idle for a bit but its no problem as the first thing I do is to check WhatsApp when I get phone in hands.
Now on stats, screen is again at 1st position (as it should be I guess) with 35,66% power draining;
2nd is WhatsApp. (13,57%)
However there is still a bit of battery drain caused from something else. When I go to sleep I always turn phone off. This night it was at 43% of charge. When I turned it on it was still at 43%, but went down to 39% in less than 5 minutes even if not in use (used for, maybe 30 secs? Just checked WhatsApp).
I don't know what's going on.
idk why but this started happening on 11.0.3, before this it wasnt draining as much, but ya I noticed this very recently, it went up to 40% batt drain for me too, I reinstalled it and used the battery saving thing on it and my battery drain's fine now, I don't see WhatsApp in my battery usage menu, but sometimes I miss push notifications so that kinda sucks :/
hope WhatsApp and/or xiaomi fixes it, or if LOS or pixel experience gets stable enough I'll flash it, hope the battery drain's fine on those roms
I am also having huge battery drain in standby , around 2 -3 % per 1 hour.
Tried unistalling all social apps but the drain persists, also phone is not going to deep sleep. Now im trying PE rom and standby drain is down to around 1.6% per hour which is too much for this chipset (k20 pro in standby with same apps is around 0.5% per hour)
