[Q] Weird "battery drain" when lightly using the phone

Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance

I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.

Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).

I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.

Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.

@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?

Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?

Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/

I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.

I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.

Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.

What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.

The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.

Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.

I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.

[Q] Is it normal for my battery to be so bad?

Hey all!
I've bought my Optimus 4X HD recently. I'm loving everything! Except the battery...
Today, I've tested it again and here's what the battery is able to do!
- 6 hours of standby, 3G and Sync enabled
- 4 times checked mail for like 4 minutes total
6 Hours later: 30% remaining.
Is it normal for this battery to be so weak? I've "calibrated" (drained to 0% and charged to 100% - left it for a long charge the first time too)
If it's abnormal I'll contact the helpdesk and see if they can replace my battery, just want to be sure if it's normal or not.
Software is latest available, non-root, very few apps -- verified with taskkiller of AVG: nothing is running in background or anything.
Thanks!

I think there are some wake locks denying the system to go into deep sleep.
Search the forum for solutions, it's a well discussed topic on here
Sent from my LG-P880

I usually get at least fourteen / sixteen hours on a single charge when I unplug it in the morning before work, varies with how long the Wi-Fi turned on, and I get at least three hours of screen time, one or two of voice calls. I also have mobile 3g data always on with alerts for email, Facebook and Google+. Usually I listen to music for about an hour and half too. I'm running the 20a euro rom official, rooted. Try factory resetting and rooting to remove bloatware and LG logging software.
Hope this helps!

Very few apps installed by you... there is a lot of stuff running in background that you don't even imagine.
Search for the threads about "battery drain" and you'll get some more info.

Do you run the new 4.1 Jelly Bean? There is some huge debate going on, how the update affects battery life. Personally, I ran into huge battery problems after updating to 4.1. The drain was especially heavy during the night, when I usually active airplane mode. With ICS I lost about 1% during an 8 hour night, under JB it was 20-30%. I read up on the threads in this forum and followed many suggestions. I started to monitor battery drain with different apps running/frozen, wifi, 3G, airplane mode enabled/disabled and so on. To analyse the battery I found the apps "CPU Spy", "Wakelock Detector", "GSam Battery Monitor", and "Battery Log" helpful.
But to be honest, I am no "android pro". I monitored my battery drain for over a week and did not find a satisfying solution for the problem. Thanks to this forum and many excellent posts I managed to roll back my phone to 4.0.3 ICS. Now my battery drain is the way I remember it and I am happy again
For me, this solved the problem. Although I do not run JB, and some of the enjoyable improvements it had, anymore. I know that for some people rolling back is no option. If you cannot locate the battery killer easily and you are willing to play around with your device (rooting, freezing apps...), you might as well roll back and give that a try.

You should explore your device and your stock apps...
My battery last in JB for so long as in ICS.
If there are differences they're small.

Yes!
Thanks all, very useful replies!
I've tried simply factory resetting it and, for about 3 hours it stayed on 100%, 2 hours on 99% and etc, very awesome!
I then set up my mail and other things and it went bad again. I had this sync symbol in my notification bar -- no clue why it was there all the time.
I googled why it was there and it's because the sync fails so it keeps trying. I removed the picasa for the email account (because uni mail doesn't support picasa and other google services) and my battery is top notch again! For now at least .

Looks like you're on WiFi which has good standby time. 3G standby is not good at all. That's when baseband_xmm_power starts acting up for me.

Following is my Battery usage still left some 17% with normal usage.

mine is bad because of the baseband_xmm_power wakelock, had this on stock 20A but didn´t had on 10h... as far as i can search, there is no solution other than revert to old 10h....
I bought a spare battery so i never run out of juice! Reverting firmware is not an option for me.

P30 pro bad battery life

Hi guys! I have p30 pro with 153 software. I see that many people are getting SOT around 10 hours. I'm light user, i have disabled everything that i don't need to save battery, togled dark mode, apps to manual launch too, I have good reception but I am getting about 6 hours,
6.5 hours of SOT and as I see everybody is getting better SOT with similar usage like me. Look at the screenshots.

Any rogue apps? Apps which keeps the phone awake?
Usually with 6.5 hrs of sot, you should have at least 20% left.

puzzled because other people getting great battery life.
After a little while (1 week) , I did a factory reset and did not import any setting through Hi Suite. I start fresh. I did not update any apps at all, just the system update. Then my battery life is great as it suppose to be.
It last for 5 days with great battery life. Then, suddenly the problem reappear again. Not sure what caused it. For me, I realised the "Phone Services" usage was at 34% ( normal usage is adound 0.8%) - >look at setting>battery>usage. I really hope somebody can provide ideas on how to solve this permanently.
Atleast I have confirmed it is not hardware problem. Most probably is software related issue.
Wjat kind of app caused this kind of battery drain.

I may have a solution to drastically improve battery life but it's a bit tedious and time consuming.
Go to Settings - Apps-Apps again and open each app installed on your phone and for each app go to Data usage and uncheck Background data.
Warningo this only for the apps you know you won't need them to be running in the background!

I had the same problem.. Had battery drain 10% per hour with/without using the phone..
I have cleared the cache and turned almost all apps in apps launch in manual mode.. Since then I have around 7-9h on screen time, it varies but I am not sure why.. However, a few days ago I chose only 3g in network mode in settings and got 11h on screen time after that (youtube 4,5h, fb 2,5h, instagram 2,5h and some other apps)-basically all SOT was on apps, so those 11h makes an amazing result... It is yet to be tested whether that 3g settings made the difference, maybe it is just a coincidence..

I did this for every app and disabled background data for all apps with the exception of a couple of them I use daily (Whatsapp, Gmail, Phone, Sms) and it made a tremendous difference in battery life.

If you have better signal with 3g it would explain the better battery, poor signal is the worst for battery.

I guess that is the catch, my 4g coverage is not so good.. I am getting 12-13h on screen time regular now, using apps like youtube for around 4-5h, facebook 3h and instagram for 2h.. The rest are phone calls, camera and other apps... The battery life is amazing..

I think I figured out why my p30 pro had a poor battery life before. The battery are draining abnormally even without using it.
Previously, I was using dual sim card.
1st sim was a 4G sim that can (call sms and internet)
2nd sim was also 4G sim but solely for internet purposes (cant call or sms- it has been set that way by the telco).
What i noticed was whenever this 2nd sim card was inserted, the "Phone Services" usage will spike and it was used by Sim Toolkit apps requesting Location all the time which sucked out the juice.
I didn't suspect the 2nd sim card at first because I did use it on my Huawei Mate 20 and the battery was superb.
I did not know why the second simcard behave this way when inserted in my p30 pro...
So now, as a solution, I only use my main simcard. Battery was again great. Got around 7hrs SOT with 25% battery left.
This is good enough for me. Also today I was recording 4K videos. Perhaps that affect my SOT.

Hello, do you know what is the Huawei data management services,it drains 7% of my battery
Thanks

I wouldn't swap my phone for anything else even after the ban.
5:30 hours sot with 50% left.

If you have Facebook ,Instagram, or Snapchat that could be why.. Lightroom is using a lot as well

Terrible SoT..
Hi guys,
I have serious battery problem with my p30 pro. While others are getting 8-9 hours of SoT. I am getting max 4.30 hours. I don't play games there is not a one in my phone. Usually using just for whatsapp and surfing. I don't have Facebook either.
Always on mobile data and, 2-3 hours hotspot on in a day.
Could you please tell me your opinion what is wrong with this device. I added some screensshots from batterystata app

You know Hotspot really drains the battery right? Can you not use that for a day to compare battery stats?

This is the current SoT from my Huawei P30 Pro (VOG-L29) with the brand new EMUI 10.0.0 (Android 10, stable).
Amazing work from Huawei ???? ??

This is the current SoT of my 2nd day of continuous usage without charging the battery (down from 100%).
I have always the GPS signal turned ON, as well always a net connection (Wi-Fi or mobile data, but not both at the same time). I've also kept every single app open (w/ minimize swipe-up ?? gesture).
I also have my Huawei Watch GT-614 continously connected by Bluetooth to my Huawei P30 Pro, using Huawei's own Health app always running in the background, continuously measuring my heartbeat and counting my footsteps as well.
PS: this time, half battery gave me more SoT because I didn't turned ON the Performance Mode at any time

Although I turned off the settings I used, I still could not do this for more than 5 hours.

Battery is draining extremely fast on Android 12 (BULK) as well...
Is there a way to know if our phones haven't been manufactured by Samsung?
- There is Korea but also Vietnam etc... this might have an impact somehow?

What are you doing on whatsapp....that's a huge drain....

whatsapp is always a huge drain if you use to send and receive messages. My solution to this was enable multi-device login. I, now, use Whatsapp mainly on my computer when I'm at work and then revert to the phone when I'm off. The led to a huge difference. What used 25%+ for whatsapp..now stands at 4-5% over the day.

Morning 7 to 5pm I m using WhatsApp for work. I m using 2 WhatsApp. Work WhatsApp isn't stop every minute always receiving several message. I can't stop WhatsApp because of work. I think that's why WhatsApp percent is so much

I've seen a maximum of 5 hours of SOT since I got the phone. My sot time is very short when I see other people's sot times. I always use the phone with the following features; +4G +always bluetooth +always location + no wifi +always sync +dolby atmos +dark mode +when i got notifications aod. Although I turned off the settings I used, I still could not do this for more than 5 hours.

Does your battery run out by the end of your typical workday? Do you have to charge it during the day everyday, or can you get to the charger comfortably when going to sleep at night? SOT by itself isn't a very good metric when seen in isolation.

In a day average I have 4 hours screen on time and I m using in a work phone around 4 - 5 hours. That's mean every noon I m charging phone if not it finish before leave work.

Are you mainly on Wi-Fi or mobile network? OP is on a building site so most likely on mobile network most of the day

So your battery level goes to 20% or below by every noon? Sheesh, that is indeed potato battery life...
But your screenshot suggests a pretty good standby time, nearly 11 hours usage and 72% remaining...
Maybe post the battery usage screenshot once your battery dips below 20% so we can try to pinpoint the issue?

Actually my battery level around %50 in noon. For example this screen shot is today after noon. In noon was %100

I am 90% sure that your battery drain is caused by the mediocre 4G signal which is used for internet at all times. A lot of power is basically being allocated to get a better signal and thus while you use WS all the time, your batt drains FAST. If you happen to have Wi-Fi for a day or two and the signal is maxed out, the battery will surely last longer. Generally speaking though, you cannot compare other peoples SOT to yours as most people do not use WS as much as you, nor 4G at all times.
There might be some other extra settings that could be altered to improve battery, like:
adaptive battery ON
enhanced processing OFF
location OFF
background data OFF
resolution to FHD
background usage limit to put rarely used apps to sleep
NFC OFF
nearby device scanning OFF
And of course the last version of android 11, as it seems A12 is not yet worthy or ruling the S21U. Sadly I have a feeling that Samsung might not fix A12 for the S21U as they are now releasing the S22. Hope I'm wrong.

The Big Battery drainers:
Screen - If you have manually set it high - Try Auto
Mobile Signal - Nothing you can do if its poor - unless possibility of WIFI
Location - Always On is a no no if you can help it - try use when app open only.
Background Data - Turn off for apps which its not reqd .
Also Since Android 12 I also seem to get lower SOT although my phone battery has been same since android 11. Im not sure if they changed the way they show/measure SOT now.

Question Battery life on my Redmi Note 10 Pro became unexplainably crappy

My phone was purchased a little over a year ago. At first it probably needed a full recharge maybe once per two days, so I doubt it went through more than 200 charge cycles.
The screen on time when new regularly surpassed 12 hours with browsing and some YouTube. I suppose it became a bit worse as time went by, but the current SOT is terrible and also unpredictable. Again, it's mostly browsing on Chrome and YouTube, and it can be between 7 hours SOT to 10 maybe. The MIUI was updated to 13.0.15 I think a couple of months ago, and perhaps it became this bad after the update.
Does anyone else have this? The battery usage breakdown also doesn't make much sense. Chrome is often at the top but it counts as if only a small fraction of its usage was CPU foreground. Android System is often third-fourth, and the Cell Standby can be about 5%, but the drainage when not using the phone is sometimes a few percents every hour.
I revoked almost all of the system apps and also removed "Modify System Settings" for all of them as suggested somewhere, but that doesn't help.
Any solution?

use the dialer and tip *#*#6485#*#*
MF_02: should be the full battery cycle
MF_05: remain capacity in mAh
MF_06: designed capacity in mAh

I have MF_00, 01, 03 and 04 but not those suggested values.
Also, it seems this phone uses a lithium-polymer battery and according to online resources that material is rated for about 300 recharge cycles. Does to mean it's actually expected to degrade significantly after just over a year? I will note there's a battery health status (MB_06) simply saying Good.

Had the same problem, but I bought mine two months ago with global MI 13. Didn't use phone much but Chrome was always on top of the list with minimum to no usage at all. When I disabled Chrome with mi tools, battery was good again. Try debloating with mi tools if you don't have root, should do the trick.

The question is whether it's actually because of Chrome or that there's something inaccurate with the battery readings? I prefer not to disable Chrome.
What SOT do you have with full charges?

To know that. Disable Chrome temporary and use another browser that time.
There could be a good chance that background use of Chrome is because of installed bloatware.

Are there any examples of removing Xiaomi bloatware actually improving battery life?
I know you can't remove Security as it bricks the software and this seems like it might be the one thing that actually uses background battery, but the app is revoked on my phone anyway if that actually does anything.

I know there is a list of removeable Miui bloatware, but because I choose for a custom rom, I don't know of explicit examples.
In the past, with another Xiaomi phone I have done this and I know that this minimized the ads then, but can't remember the BB improvement.
I depends what the bloatware apps tries to do and how.
If they use network connections or cause wakelocks that prevent deep sleep etc. removing them should improve battery life.

I don't have any ads on anything other than regular ads in some third party apps.
Does the debloating method delete or just disable the apps?

You better read the threat about debloating
Without root you can only remove this app for a user.
So in theory the app is gone for you, but it will be still there and is easy to install again.
You need adb for this and can remove/install apps the easy way with a script or manually for every app.
Personally I think you must be conservative with removing system apps to prevent malfunction.

SOT was good, 1st few charges (using from 20-85%) i got between 7h and 8h. I never go to 0 and 100% if i can help it.

On what kind of usage? Because as I said, for light usage I got around 12 hours SOT at first.
EDIT: Ah, you referred to 85% to 20%, that could be around 12 hours for the entire battery.

Something similar happened to me this night. Bought the phone a couple of months ago, currently on miui 13 eea, rooted, sleepy kernel with limited cpu freq. With light usage the minimum SoT i got was 12 hours. However this night battery went from 15 % to 3% and the phone was totally inactive. This is the first time i see this issue. Dont know the cause.

Just this night it seems my phone has lost almost 20% on its own. The breakdown is like this:

"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

And "other", whatever that refers to, is at another 31%.

For me "phone idle" was about 20% of the usage. However this night everything was fine.

It seems the issue might be a bit better now, as so far the phone has been off the charger for about 5 hours and I have around 92% charge left over 50+ minutes of SOT.
I did "uninstall" through ADB a bunch of built in apps and software as suggested in some bloatware lists, although not everything (and some that weren't suggested in all cases but were supposedly related to mi account stuff), although another thing I did was unlog the mi account from the phone. I think I might have logged it in about a month ago when I wanted to change something with my mi router, and although nothing is set to backup to their cloud perhaps it did work in the background in some ways which heavily drained the battery?
I'll see when the battery is close to 0 what is the actual SOT.

Honestly i don't really know. For example the past night i left my phone on and everything went fine, no drain or strange issues. I always use the battery saver mode and i disabled most of the miui apps with luck patcher, except security, clock and some basic apps

Listen, the change in battery drain after the debloating I did (or just the logging out of the mi account, I don't know) is incredible! As I mentioned, it used to drain almost 20% over a 7-8 hour night with the battery breakdown I pasted above, and now it's 2% to 3% and looks like this:
Makes me wonder what it was doing in the background when all of the optional battery-draining features were supposedly disabled.
