Possible Explanation for SIM Card induced battery drain - Xiaomi Redmi Note 7 Questions & Answers

I have no idea, what is happening with my sons phone, maybe anyone has an idea:
My son changed his pin and forgot it, so after numerous tries, we had to reset the whole phone. I never update the firmware, so the firmware version was MIUI 10.3.5.0 from Summer 2019, when we bought the phone. After resetting, I decided to update the phones firmware to the current MIUI 12. No problems so far, but in the next morning, we saw the battery drained over night 40% with no interesting apps in the battery drainage overview.
First step: I reset the phone again and just made the initial Configuration (Wlan Key, Google Account). The drainage was again 40% over night with no additional apps installed.
I decided to Install non Xiaomi Firmware, so I unlocked the phone, Installed Orangefox as Recovery and then tried the following firmwares:
- Lineage 17.1
- PixelExpierience 11
- MIUI 10.3.5.0 (the "original" firmware, we were happy with for two years)
All firmwares showed the same drainage with about 5%/hour (Of cause always deleted all caches).
Then I thought, maybe the Battery had already some problems, and we just saw them now, but that was not so: We use self hosted GPS track software in all of our phones, and the protocol showed, that the night before the first reset, the phone drained 7% over night.
Then we bought a new phone, changed the SIM card to the new phone, and since then, the battery drainage has stopped.
So the situation is, no matter which firmware installed, the phone beeing directly after first configuration and with Wifi (so no need for mobile data usage), no calls, drains 5% an hour BUT If I pull out the SIM, it looses only 1% over night.
How can that be?

@admins: please delete this thread here, I tried again in the general section.

[Q] Exynos KitKat Battery Drain - gpsd & l2_hsic

Hi Guys,
I upgraded my Exynos Note 3 to Kitkat about 1 month ago, and everything was fine till about 3 days ago when I started experiencing some really bad battery drain. For the last three nights, my phone does not go into deep sleep mode at all. I first noticed this because I usually switch off data and wifi at night. Normally, I'd loose 3% battery overnight, which is good. About two nights ago, I woke up in the morning and I had lost 40% battery (90% down to 50%) overnight! When I checked out the battery stats, "gpsd" had used 80% of the battery.
Since we no longer have batterystats access in Kitkat, I installed the desktop version of WakeLock Detector, enabled USB debugging mode and connected my phone. Phone had basically been awake 97% of the time. Under kernel wakelocks, "l2_hsic" was shown as being the culprit. Now I have searched through various forums online (including xda) to try and find a solution to this. Suggestions vary from home screen replacements (nova launcher) to mobile tracking software (cerberus/findmymobile etc) to generally anything that uses location services. Some even suggest clearing application caches, disabling location services etc. I have tried every suggestion with no change. I uninstalled all mobile tracking apps, turned off location reporting, location history, and eventually location services. I've removed all battery stats apps. I uninstalled all my apps and re-installed them one by one, all with no change. Finally, I backed up my phone and did a factory reset. That seemed to work at first, but after about 3 minutes, "gpsd" was back again, and my phone would not go into deep sleep.
I've done 3 factory resets, and with no google account or samsung account configured, I still get "gpsd" rearing it's ugly head, preventing the phone from going to deep sleep and draining my battery. I'm at wits end.
Anyone know how to fix this? Would appreciate any help!
Anyone!?
OK, so I decided to take out my SIM card, just to see it'd make a difference, and what do you know! "gpsd" no longer takes up CPU time! So this is somehow related to my SIM card? Funny though, coz I'd even tried putting the phone in Airplane mode, but "gpsd" was still taking up CPU time. Does that give anyone an idea as to how this can be fixed?
bump
I'm having exact same issue with my exynos Galaxy S5, shame Samsung.
For the record, my issue fixed itself. Didn't do anything at all. It just went away and never recurred. I'm on the Russian lollipop ROM now, loving it!
Almost a year after the issue fixed "itself"... I have the same problem with my SM-N900 running offical lollipop, Im afraid I cannot wait a year to let the issue fixes itself... and cannot find a solution either.
Anyone that have managed to solve this?
THANKS IN ADVANCE!!

All of the sudden major battery issues

Hello,
My phone was working great since March - lasted all day and then some.
Within the last 3 days however, it has been discharging at an incredible rate...the biggest issue battery user is "Android System" at 47% ... with only 2 hours on battery the phone is at 80%.
I saw a thread similar to this issue and I spent two hours doing a complete factory reset and setting everything on the phone back up however that provided no relief to the issue.
Why did this all of the sudden just happen and for the love of god can we fix it? I am about to ask for a new phone.
What is your firmware version ? When did you last update the firmware ?
Do u have exynos? The newest update raised android drain for whatever reason
First of all , do a factory reset and wipe cache.

Within the past week, battery drain went from 7% over night to 40%?? (G950U / At&t)

Within the past week, battery drain went from 7% over night to 40%?? (G950U / At&t)
This past week, I've noticed my battery is draining excessively faster than it has over the past 2 months?!!? I can literally watch it drop a percentage point ever couple of minutes. A few weeks ago, it was draining 7-10% overnight.... The last few nights, it's draining 30-40% overnight. I checked my battery usage, it shows nothing out of the ordinary (Screen, Android system, Kernel, Facebook, ect...).
I just did a factory reset to see if that help is, but what could have caused this?? A rogue app or something? I have downloaded, and deleted, several new apps over the past 2 weeks (not sure if that can cause issues??)
I downloaded the Samsung package disabler last month and disabled every "bloat" thing I could find, including Bixby (yes, I tried it the Bixby update the other day, but like Google Assistant better). I double checked this last week, when the drain started, and everything was still disabled. So, I'm at a loss??
I hope the factory reset helps??
Its always an app causing it or a sync issue with one of googles services.
have you received a SW update ? / are you on official ROM ?

Samsung S8 Oreo - Battery Drains FAST

Hi,
My Samsung S8 since last upgrade to Oreo was a complete disaster. Just to be clear battery life during Android Nougat was good and it was the first thing ive noticed that samsung completely stepped up their game since their battery disaster on their certain phone model. Battery life would run at least from a day to 2 before recharging. Ive noticed there are other threads similar to these so i knew im not the only one affected, my colleagues also experience similar issues since upgrading to oreo so this is not something isolated to my s8 phone.
Few key points that ive noticed since upgrading to oreo:
1. Going to settings then battery usage. Screen would be the foremost battery hog at 26%, followed by Android System at 13%, then Device Idle at 9-8%. Cell Standby and Android OS remains normal.
2. Go to Settings then App. Ive noticed by checking each one of the apps that beaming services, device maintenance, settings, gear vr services were among the ones that took up most of the battery usage this is excluding system apps like AASAservice, etc.
3. Go to settings then data usage. The Android OS is sending or receiving 100MB of data (still counting). I wanted to know what are these data that is worth 100MB.
4. Device easily gets hot even light use of facebook, ig or 7 minutes of youtube video.
5. It sometimes restart, this is rare but ive noticed it since fingerprint cannot be used initially when there's a restart.
Now what ive done so far:
1. Cleared partition cache by holding bixby btn, volume up and power.
2. Disabling unused apps, even certain bixby services, etc.
3. Went to developer option and disable always on mobile data.
4. Factory reset device hoping it would go back to nougat but it did not. With a mint condition reset, it still drain too much battery. (without any third part apps or data restore)
5. Called up samsung customer service but was told to go to service center. Went to service center they check the ASOC of battery (which i think is unrelated) and according to them reprogram oreo. which did not help. wasted my time.
Now what is the implication?
1. I need to charge my phone at LEAST twice a day.
2. It heats up the phone which would definitely have negative impact on the longevity of this device one way or another.
3. It drains too much battery, with the amount of charge discharge multiplied at least by 2, this will literally messed up the battery life in the long run.
4. Im currently using 2 phones and my samsung s5 which is a 4 year old phone had better battery life. lol. Since in just 3 hours it consume almost 40% of battery.
There are tons of related post like these on different forums and on reddit but i surmise i should dig more on this problem before writing a more concrete post. At this point, i can only see 2 remaining options: 1. There is a step online that would revert the OS back to nougat but this would involved third party apps like odin, there are risk involved like phone brick, etc. Im not sure if it will void the warranty. OR i can just wait for a patch from samsung.
Now SAMSUNG NEED TO FIX THIS ASAP or provide us a way to revert back to nougat. With the s9 just available at the market, this terrible oreo release could not come at better time. I know there are several issues like the battery issues with their previous note model and Apples intentionally slowing down their phone, Samsung got to fix this fast before this issue becomes a blowout and many people will start to notice.
There are several threads about this: https://forum.xda-developers.com/galaxy-s8/help/to-to-fix-battery-drainoreo-t3771716

What security patch do you have and what can you see under "Baseband"? Everything will be fine with latest March security Patch and CRC7 Baseband. Just be patient, if you do not have it, yet.

Man, i´m totaly on same boat!
In CRC7, i'm experiencing terrible battery life. Max 2.00 to 2.30 Screen on time in one charge. Now, for the first time, i have to recharge my phone befoure dinner.
Wifi , Bluetooth, Aod On, location history Off.
It´s the worst experience on any phone that i had in the past.
Like you, already disabled some apps, clear cache and already done a fresh install. Nothing works, nothing improved my battery.
I´m thinking send it to warranty, but it´s probaly not worth the time...
Maybe it´s time to forget about Samsung phone and move on. P20, or even iPhone X...
After updating to OREO and updating all galaxy apps, "beaming service" was draining my battery (67% of the battery actually). After uninstalling the updates on beaming service, the phone seems fine now. Maybe uninstalling the updates of which apps are draining the battery could help you guys as well.

ive tried that before but after fresh install. beaming service could no longer be disabled, nor its updates uninstalled.
Besides other apps are also draining battery like AASAservice, settings, device maintenance, etc.
I received an update yesterday for the CRC7 March security patch.
Battery life aint any better

You're right, that can't be disabled but I was simply able to uninstall the updates by clicking three dots top-right corner of app info screen. I've the latest version CRC7 on the phone by the way.
Hello !
I've been s8 for three months and I've never had any particular problems, I've upgraded to CRC7 (second update of Oreo) and I've already got twice the phone with a flat battery:
last week in the morning I found it at 1% from 35% the night before (during the night only the gsm network was active, everything else off); when in doubt I did a factory data reset by installing only minimal applications (FB, whatsup and little else) and I installed the Accubattery application to monitor the battery.
Last night put away (active gsm only) at 65% of residual charge and this morning after 10 hours it was 5%: 60% of charge consumed in one night.
Android does not report any abnormal consumption of any application .... it seems an anomalous battery drain
I enclose battery data screenshots; is not that the new Oreo update is buggy? or could the battery or the phone power circuit or the radio part that consume excessively might have a problem? Before bringing it to service I wanted your opinion and in case I wanted to try to put back the CRB7 version of Oreo .... how do I do it? do I lose the guarantee in this case?

i'vre tried with beaming service but clicking three dots top-right corner of app info screen not available for this app : three dots top-right corner are for all the apps
Do you have a drain simillar to mine ? Help me please !!

I have the exact same problem as you and many others. I have tried various things to solve it and I concluded on that the modem firmware has a serious bug . airplane mode consumes more battery than on cellular. To make sure we are talking about the same thing please try removing your SIM card and let it all night . By the morning you have to be -2% of the battery . With the SIM inside now you have to drain 15-20% . If thats the case for you , you make sure that its not a faulty device and there is no drain from your setup (like an application draining etc .. in this case factory reset should fix it).
Cinfirm your findings and lets hope they will release update soon.

he doesn't do it every night, but random : in a week it happened twice
It's not in airplane mode, modem is switched on only for phone line (LTE off) ; I already tried two factory reset
Yours is affected only in airplane mode ?
Tonight , my s8 have to drain 60 % in 9 hours !

It drains in general but while in cellular it's difficult to distinguish if it's a bug or bad signal . Each ones phone may consume different amounts of energy depending on coverage etc. But in airplane mode you can be sure it's a bug because antenna transmission should be off and therefore not consuming energy . Just try as I said just to be sure we have the same issue . One night with airplane mode and SIM card in and another night airplane without SIM. You should see great difference .

Tonight ( gsm on ) have no drain : 0,3 % / h. ( 3 % in 10 hours ).
if it is faulty the battery should always do it?
Did you try to see if it drains, leaving the radio part active?

This will not help determine the bug because as I told you it's signal dependant. It's 3% in 10 hours because you probably had good signal . Else it could be more and even if you contact a service they will say it's not a bug but the signal . Anyway if you were with data on and 4g seems more than fine to me . Now if you try this night airplane mode for 10 hours it could drop 15-20% ... is this reasonable ?

in airplane mode is a bug, but a 60% night-time consumption with active gsm?
0.3% / h. the device was in the same position the night before when it consumed 60% in 9 hours

Your case seems more like a random application wakelock . Did you do a reboot between the 2 nights?
To distinguish better the cause of the drain , when you see an abnormal consumption try removing your SIM card for a while . If this fix the drain it's the buggy modem/radio firmware ...

Massive battery drain mi 9T

Hello guys! Yesterday I updated to miui 10.3.15 and i experienced massive battery drain overnight from android os. Last night I charged it full 100% and in the morning it was 19%. And this is with only 20 minutes of SOT. What may be the cause? Airplane mode is on, because I am on vacation in country where i cannot use roaming. I deleted the cache and rebooted the device and I think it is fixed but i will know when I fully charge the device.
try new beta android Q, is awesome for battery life
"9.9.26 - First MIUI 11"
Install Europe version ?
Im on mi-globe 9.9.26 and i suffer battery drain and heating issue
The pix for reference
This happened to me once. I believe is not a battery issue it's more like a process keeping wake up and eating the battery. When this happened to me I reboot the phone and charge it again and issue not happened again.
This keeps happening to me every few days.
I had to manually disable autostart for all apps. And i did not even know which ones I need and which ones I don't.
But it did not help, it keeps reapearing.
Same
This happened to me a few days ago and happens again every few days. I don't remember if it was after the installation of MIUI 11 or earlier, but I would think it is a software issue that Xiaomi should investigate.
The only solution I found was to close all applications and restart the phone before charging it.
I have no issues, my advice is whenever installing an os update it's always best to do a factory reset in order for the phone to run at optimal performance. When i updated i did not reset my device but i made sure to clear all app cache and reboot the phone after update. My SOT is normally 8-9 hours, also i made sure all my apps are up to date and their are no background apps that are draining my battery.
