Has there been any fixes to the battery drain issues with 7.0 update on Honor 8 (US)?

Hi, I have upgraded to Android 7.0 on my Honor 8 yesterday and since then the battery is draining at an insane pace.
I used to get an overnight standby drain of 3-5% on average with 6.0 and it is well over 25% with 7.0. Something called "Android System" has consumed a disproportionate majority of the battery. A similar problem is reported here: https://forum.xda-developers.com/honor-8/help/battery-dropped-40-nougat-honor-8-t3558197
The background app settings haven't been changed -- have about same 6-7 apps like Whatsapp, Outlook, etc. However, when I open the current background apps, I see a few unprotected apps (like Maps) also running in the background. Is this a bug?
Please help out, if there are any fixes.
Thanks.

try apps like greenify to fix wakelocks

Many users are dealing with this problem and I've reported before.. This update is broke, and shouldn't have been pushed officially. There are a lot of bugs, and the most irritating one is the battery consumption.
And I don't think Honor is going to fix any of it since we're used to them not caring about what we deal with.

My personal experience with the Nougat update was that battery drained quicker than usual for the first few days, then it stabilized to normal levels (i.e. more or less what it had been in Marshmallow). I was expecting this behaviour, since system upgrade clears out battery optimization data, and it takes a couple of days for the OS to learn what to optimize. Also I suggest you recheck your battery saving settings (Both the Huawei version under Battery settings and the Google version under Applications).
And since someone is going to ask anyway: no, I haven't done factory reset. There was no need.
But this was just my personal experience with nougat. It's of course quite possible that for some people there is a real constant battery drain (wouldn't be the first time, I had a similar experience with my old Motorola when I upgraded to Lollipop a couple of years ago).

It's not the update. From my experience, I had this issue since I bought the phone. I would factory reset it all the time and this issue would persist.
It turns out that in my case, I would always turn off LTE and use WCDMA instead. My logic being that WCDMA uses less power, so therefore I would get better battery life. Nope. There's a glitch that happens if you do this and have wifi on, It doesn't let the phone go into deep sleep. Ever. So your battery drains about 20℅ overnight.
The solution for me was to simply leave LTE on, and now my battery consumes like 1℅ overnight.

For those suffering from battery drain, check your consumption and see if Google calendar sync is taking up a lot of it.
I had that issue, and had to manually kill the sync (from the accounts screen).
It seems to be an issue on all Huawei devices on 7.0, the native calendar isn't playing well with sync, and unless you're rooted and can uninstall it, you're stuck. (I'm waiting to root until a patch comes out for all these issues first)
All in all, if this is how Huawei treats their devices, and their customers, I won't buy another one of their devices.
I updated via Charles method, but my mother's L04 still hasn't gotten the update. And probably never will unless I do it manually.
Very disappointing.

Thanks. I was thinking of waiting for a couple of days too. Its just been 12 hours and the battery is almost down to 25% from 100%. If it doesn't improve in the next few days, I'll revert to 6.0 with which I had solid 1.5 days battery life for my usage level.

On my frd 09 i got a update after the nougat update which fixed my battery drain it was around 356 mb big. But since maybe 1-2 weeks already. And my battery drain is lower as on MM

I do feel Nougat on my L14 is draining faster than MM. It's mostly Android System or Android OS so I have no idea what is within that taking the power. There is also a weird bug with LTE enabled when I make a call to another cell phone. Most of the time, my phone says it's ringing on the other side but there's no "ringing" sound on my side. Weird. Turn off LTE and you can hear the ringing.

It is always hard to determine what is going on in these sort of circumstances. For me, EMUI 5 doesn't seem to have badly affected my battery life. I just got almost 3.75 hours SOT using Waze for navigation, and still have about 30% battery. According to the detailed power info, Waze was using 1340.27 mAh.

Just for balance, my experience is more like this one, although I don't think I had to wait days for it to not be a battery drainer. Is everyone in this thread talking about b360? (for whatever variant you have)? I did see this on b320, but have used b360 for about 1-2 months now (Charles) and haven't had any noticeable difference in battery life from Marshmallow. It drains 1-3% / night. Screen on time , say browsing is pretty regularly 5.x hours, and typically I get 2-3 days out of a charge.
I believe everyone that says they've got a problem, but I guess some of us got lucky. Just so it's known: Mine is a US L04*b360 variant.
Note: Just as a possible point of difference. Before I was on b360, I had the phone rooted, with TWRP, and had to wipe the entire thing , rollback to b160 and use Charles to get b360. I never did a reset and I don't turn off functionality. Also, maybe most important. I don't use social media hardly at all. I haven't got Facebook or Twitter installed because I don't like either.

i would suggest a factory reset, then install only essential apps and test it for a couple of days.
L04 here, OTA updated and I'm seeing better battery performance than MM.

Try going into settings, accounts, google.
Look to see if anything looks like its stuck syncing. If there is, turn that off. Go into the app that was stuck, and swype down to cause it to refresh, then go back into the setting and turn that syncing back on (if you want it to sync).

Does root and Greenify help?

I contacted Honor Support and reported the problem.
I was suggested to "Wipe Cache Partition". It helped a bit but the battery was still draining at a faster rate than 6.0. So I have now been wiping cache partition on a daily basis after a full charge.
I know it doesn't make much sense but it helps contain the drain a bit, at least when connected to the Internet via WiFi. The drain rate remains the same as soon as I switch to LTE (about 2-3% drain per hour with roughly 5-10 minutes SoT).

My phone wasn't rooted. I'd have tried Greenify but it wasn't any app causing the drain; "Android System" is the culprit. I don't know if Greenify could help with that.

Thanks for your comment. My model number is: FRD-L14 and the build number is B360.
Honor Support recommended to "Wipe Cache Partition". I did that without much luck. I have now been wiping the cache partition after every full charge (which is a ridiculous thing to do!). It does help arrest the drain a bit but only on WiFi. As soon as I turn on the Mobile Data, the battery drains at insane speed (about 2-3% an hour with just 5-10 minutes of SoT).

Battery Drain on Android Pie?

Hi All--
I've been on the Android P Beta for a while.
However, starting with the final beta that was released (and now on the final version of pie) I've been experiencing really quick battery drain.
Tried a total wipe and restore, and the same thing. My wife (also the pixel) isn't having those issues at all.
Thoughts?
(nothing shows up in the battery section)

Yes, I had great battery life. Then once Android Pie was released, jumped on the beta to get 9 sooner. Then got the upgrade from beta to final and battery life is horrible. I did not factory reset, I have battery saver on and it doesn'tseem to matter. If I leave on standby, no issues. If I use the phone, it can bleed as much as 10% per hour! Unacceptable. I may try factory resetting, but idk...

have you allocated sufficient time for app battery optimization?

I also have a pixel, Android 9.0/Pie (bought it brand new three days ago) and think battery is draining very (!) quick.
Yesterday I had roughly 2.5 SOT (with battery saver enabled) and this seems consistent with what I can expect typically. I did factory reset and have tried restricting "background activity" for my frequent apps - seems to make no difference. Obviously it had not time to do full battery optimization yet I guess, but I doubt it would mean a that big difference?
Saw a thread where someone mentioned it seems CPU-freq is high/inc. very rapidly when just tapping the screen (GPU-0%), and I can agree with that although I have not the prev. experience of what to expect.
My previous experience is with Xiaomi mi6/mi5 (lineage 15.1), similar usage would give 2x or 3x SOT (however with some other hw-issues.. ).

Flashed factory image without -w/"wipe". Will that do or should it be "full" factory reset to make sense?

Thank you for your information, I will stay on Oreo.

I don't think it would make a difference. The user data is on a different partition.
You could try flashing the image again, without Magisk or any other additions.

I had used up 50% with only 21 minutes screen on time.
I noticed the app Device Health Services, was constantly active in the background.

I had the same like the OP: everything was fine until the last beta came, and battery is draining faster, phone gets hot from even the smallest usage even in the prod release of android pie.
I was thinking it has something to do with being about 36 degrees (summer time....), but it is the same even in cooler temperature rooms. It's like if the phone is constantly doing something in the background, but only if I use it.

It has been a few days since I upgraded my Pixel 2. Battery life is noticably worse, maybe 20-30% more battery drain in a day than what I saw in Oreo.

I notice the issue as well. I did factory reset after update it's been a week. I was on beta and started noticing battery issues in the first beta and throughout. I decided to install Accubattery to track my battery usage and ended up with a result.
My phone states the battery is in good condition but this app says otherwise. I guess it's time to change the battery along with cracked screen!

i'm curious if my battery is shot as well... Seems like after I purchased my used Pixel.. the battery is not as lasting as I hoped for the smaller pixel phone... I may try one of those battery testing apps to see if it will tell me its current health..

I normally welcome up updates, but this update screwed up my battery life so bad. I mean everything was perfect until the update. Now the battery drains so fast I can watch the percentage count down like a timer and now when the battery gets anywhere from 15-40% the phone will just shut down.
I would like to go back to oreo, but it's such a pain in the ass having to back everything up and flash a ROM considering I haven't done that since before I bought the pixel

I have the same problem. I hope Google can fix it.

Wow, that is not normal. Stock android 9 with root and elemental kernel.... I go back to android 8.1.0 and wait for feature releases

I think I found an Draining App/Setting
I disable the RCS Service on my Phone. It can be found under Messages >> 3 dot Menu >> Settings >> broadcast News. Disable it.
And then Bluetooth and WiFi scan disable.

Same here, crazy idle drain after pie, only 50% deep sleep, tried factory reset and no luck

Try BetterBatteryStats. People in that thread spend their free time analyzing logs to tell you what's eating up all your battery life.

Same problem :crying::crying:

Why did the August update destroy my battery life?

I'm not even kidding. Everything was perfect and I had absolutely no problems until they sent out that update. Now I can watch my battery percentage dropping by the second and my phone will shut off around 30%.
Once again, I had no problems until the August update. I never even rooted this phone, so the last thing I want to do is to figure that out to downgrade to the last version. I will if I have to though

If your phone spontaneously shuts down with the battery at 30%, then I see 2 possibilities:
It's overheating, or
The battery has reached end-of-life
Use an app to determine the remaining capacity of your battery (usually displayed in mAh). The results of such apps should be taken with a grain of salt, but if it says your battery is only at 60 or 70% of original capacity, then it's definitely not normal.

You could try to go to recovery, wipe cache and reboot. Or, if possible, wait for the next security update and see if it gets fixed if you have a spare phone to use. These are the only two opportunities without messing around or loosing data.
A downgrade always needs a full data wipe AFAIK. If you aren't afraid of data loss, you could try a full factory reset and see if the battery drain is gone.

I noticed the same on my Pixel - i don't use it a great deal and was seeing 6 days before it'd drop to 30 to 35% battery level, now i'm seeing 2.5 to 3 days - my usage has not changed
I really don't think it's battery nearing end of life - the phone & battery are just now hitting the 2 yr mark

I don't think it's end of life either. Like I said, everything was great until the update. My GF got the same phone around the same time and I told her not to update. So she's still running the last version and her phone is still perfect.

Is the battery life still abysmal when running in safe mode? if so, it may be a rogue 3rd party app.
my battery life was crap with the kernel and android system after i updated to August as well. I assumed it was a Magisk update or module that was the issue. Once I moved to Android Pie my battery life has returned.

I haven't tried safe mode - my battery was surprising decent under Android 8. the day it updated to Android 9 it went south in a handbasket. And i noticed "battery saver" selection is no longer available
i'm trying to read up and re-learn installing a custom rom, and which rom to choose - i last did a custom rom in 2010 and haven't been near the forums since then, but this issue and the more i learn about google's surveillance collection, i want to go custom

Since you're willing to install a custom ROM, why not try to reinstall the full stock ROM first?

appreciate the suggestion - that's what i originally wanted to do and posted here a few weeks back asking how to revert to android 8 and was told it couldn't be done but i could do a custom rom
and now, with the privacy issues i've been reading about, i think i'd prefer to limit my services as googles' "product". It kind of alarmed me how sensitive the phone's microphone was - i actually wrapped the phone in a heavy towel and left it 5 feet away, and said "OK google" in a normal voice - and bam, it was opened when i unwrapped the phone. There's no reason for the microphone to be that sensitive, imho
but i'm an old fart, and the younger generations don't seem to relish their privacy like i do - that's fine for them, no judgment on my part, i just like my privacy

Samsung Galaxy A13 Battery Problem

Hey there everyone, so i have been using that A13 for a while now, the battery used to last exactly 3 days when i only used the phone to talk, and 2 days with more usage, and now all of a sudden, it's now lasting 1 day without even using the phone, i haven't installed any new app, and i haven't changed any settings, i haven't even updated existing apps, the only thing i did that was out of the ordinary was keeping the phone on for 30 days straight without shutting down or restarting, i usually restart, but i forgot to do so this time.
I was forced to restart in the 30th day because when i plugged the phone into my computer, it wasn't detected, and there was no popup on the phone, after restarting, i noticed that the battery was draining a lot faster than before, and the phone actually consumes more power while idle now, i checked the Ampere app, and it's draining about 220 mA now instead of the usual 150 mA, i think the difference becomes even bigger when the phone is idle.
I tried safe mode to eliminate the possibility of apps causing trouble, but the result haven't changed, i also noticed that the charging amperage via cable plugged into the computer is now about a 1100 mA instead of the usual 200 mA, there's nothing wrong with the cable or the USB port because i've already tried another phone, any ideas ? i'd rather keep hard resetting or flashing as a last resort.
Update : i did a factory reset, it didn't work, i did a firmware flash AND a factory reset after that, and it still didn't work.

Clear system cache.
Remove any social media trash apps...
Clean logs with Device Care.
Clean with SD Maid.
Replace battery before it fails completely and potentially damages the device

Thanks for the reply, i actually removed all removable apps and cleared caches on the remaining apps on the device, the problem persists, i think your first suggestion implies a hard reset, i will do that if i have no other option, i'll clean logs now with device care, and try cleaning using SD Maid.
The phone is 3 months old at this point, do you think the battery might actually be failing here ? also, what are the odds that it's not calibrated and thus reporting wrong values ?

You're welcome.
No. Clear the system cache, the option is found on the boot menu. Factory reset if you have done a major firmware upgrade. Do Not use SmartSwitch if you do. If you did use SmartSwitch to do your current load that may be the issue; hand load for clean load.
You can also try a hard reboot (simulates pulling battery).
It's possible a 3rd party app altered hidden user settings. This would be hard to correct. Unistalling the app may not fix it, factory reset.
Load only trusted, vetted apps to avoid this.
Malware is another possibility.
Battery's can fail at any time. Any swelling is a failure. Erratic fast charging is also be a symptom. A failure at 3 months is improbable.
Is adaptive battery turned on? Try turning it off.
Only fast charging should be enabled from that settings page. All Samsung's should be optimized for best performance. All cloud apps including Google backup Transport can cause excessive battery drain.

Okay, i cleared the system cache, apparently it changed nothing, i have never flash any firmware since i got the device, i've only done an update through Samsung, i've also never installed SmartSwitch.
I did a hard reboot, and it also did nothing, i've only ever installed apps through google play store, i have yet to install an apk on this phone..
Any ideas to check if there's any malware ? keep in mind that CPU usage is fairly low while the screen is on, i could tell using GPUWatch.
Adaptive battery was indeed turned on, but it was on from the first day i started using that phone, i turned it off now, i'll see if it makes a difference, i've only used fast charging once, but i disabled it after seeing how far battery temperature went.

Track down the battery hogs and deal with each on a case by case basis. Package block if needed with adb edit or a package disabler.
Malware is a subjective call, scan with Malwarebytes. If you didn't do anything stupid there's likely no malware. If in doubt, nuke.
Obviously something changed... find it. Otherwise it's likely to reoccur even with a factory reset.
Use a fan and/or a damp microfiber cloth to cool the phone when charging. Li's prefer frequent midrange power cycling (40-72%). Small midrange charging generates less heat and battery stress.

The phone isn't overheating while charging, the only reason i'm using the computer's USB port to charge isntead of the adapter is to prevent that kind of thing, especially in summer, i've never let the battery go below 30, or above 85, and by the way, there's an option called Protect Battery, and this limits the charge to 85, i enabled it when i bought the phone.
I'm starting to think that the battery isn't calibrated, because this time it took the phone 3 hours to drop from 80 to 79 while mobile data was enabled, and after that, it started dropping like crazy, meaning it's not consistent.
I also noticed that while having the phone plugged in to the laptop, the current calculated by the Ampere app is sometimes 1100 mA and sometimes 30-40 mA, the former doesn't make sense because the USB port is a 2.0 one, and it doesn't provide more than 500 mA.
I'll try to re-calibrate the battery, and if that doesn't work, i'll just flash the firmware anew, and hard reset after that, i'll let you know if there's any update, thanks a lot for the help.

Ouch.
Battery calibration doesn't effect SOT. If not running warmer than it use to it may be the battery or other hardware failure. If under warranty, send it in.
The one thing that has broke my Samsung's multiple times are upgrades and updates...

You're right about the update thing, now that i think about it, this started happening about 2 weeks after a security update, i don't know if downgrading would solve the problem, and i'm not even sure that it's possible because i tried downgrading on an M30s via a firmware flash and it didn't work.
Although it's a little tricky here in my country, i think warranty is my only option, anyway, thanks a lot for the help.

With Samsung's over the years I learned this rule, the hard way: Rule #1 - If an OS is fast, stable and fulfilling its mission, let it be!
A rollback to the last known good version should fix it if that's the problem... then just don't allow it to update, block updates/upgrades. I'm a pragmatist, I use what works!
This N10+ is still happily running on Pie, last update over 2.5 years. Current load in over 2 years old, still fast and very stable with minimal maintenance. That's what a stock Android is capable of. Security is not an issue. Malware has given me zero trouble, app updates though have cost me quit a bit of time to fix. Any OS version from Pie up is relatively secure unless you do stupid things. You can't save dumb bunnies, but Google tries to make you think it can. It can't.
Screw the Samsung, Google and "trusted" reviewers hype. You'll find more trustworthy information on Samsung member forums and even Reddit. Sad but true. Ever notice how all the new Samsung flagships and Google Android OS's get glowing reviews? If pigs could fly...

That A13 i have (it's not the 5G version) actually came pre-loaded with android 12, the update i did was not one to a new android version, it was just a security patch, i'll try to downgrade to the first stock firmware if it allows me to.
I'm starting to lose my trust in Samsung, you're right, they do indeed screw things up with their updates, i experienced that first hand as well, i always tell myself that they might learn but i always end up wrong.
They hype up the product only for the consumer to find out that they were telling nothing but lies, i think i'll never buy a Samsung phone again if i can't fix the issue with that one.

You will be able to reflash pre update as long as you can find that firmware. 12 had a big security flaw in it, you probably want that patched. Hopefully it was before your security update... you might want to look into that.
As far as Samsung goes I can only speak for it's flagships as I don't follow it's other releases closely. Every flagship released since the Note 10+ has been a disappointment in my opinion.
It's no accident that I'm still running 2 N10+'s, Samsung didn't give me a better option nor did Google Android; scope storage sucks. The humpback N20U was the last flagship with expandable but it had issues and the spen on the wrong side. All the variant refresh rate displays suffer from poor SOTs, reduced color/gamma accuracy and reliability issues.
With a much smaller battery the N10+ gets noticeably better SOT. It just keeps running, this one has over 8k hours on it; it looks (including the display), feels and runs like its new. It's a joy to use. The newer flagships won't be capable of this. I've lost confidence in both Google and Samsung. Not sure Samsung will ever get out of the hole they dug themselves into. They're are now experts at dropping balls... bravo.

Confirmed, it's just like when i tried it with a M30s, once you upgrade the BIT/SW REV, you won't be able to downgrade.
I think i'll try to RMA, that is of course if i get lucky, because they're not even responding to my emails, that really sucks, just like you, i've officially lost my trust in both google and samsung.
Honetly, i'm not really that surprised, especially after that video from mrwhosetheboss showing that every single samsung phone he's ever owned had a swelling battery.

Meh call them and share the wuv...
Li's have reached the end of their usable service life when they reach 80% of their original capacity. They should then be replaced to avoid a failure. So that was more the owner's fault than Samsung. This N10+ had a battery failure but again it was very degraded even though it wasn't even 1.5 yo. Mostly from heavy usage, and a couple high temperature exposures, my bad. Fortunately the bloated battery caused no damage. Timely maintenance will help to prevent most failures.

That's the thing with my phone, i bought it brand new, and i am the first owner, i have been taking very good care of it, and i always keep an eye on both CPU usage and battery temperature, i've never let the latter go beyond 36 C, sometimes i was charging the phone using my laptop's USB port just to prevent high temperatures caused by fast charging, and i've never let the battery drop below 30 or go beyond 85, i did my very best to take care of it.
With regards to that video posted by mrwhosetheboss, it was very clear that it's samsung's fault, he has a large collection of phones, both new and old ones, and samsung phones in his collection were the only ones that had a swelling battery, he even reached out to other well knows youtubers, and they confirmed that a lot of their samsung phones did indeed have that problem, they didn't experience that with other brands.
I mean i'm not surprised after that incident with that explosive Note 7 battery ! here's the video if you wanna take a look :

After the N7 nightmare Samsung probably has more design, manufacturing and operational protocols in place than most companies. Their batteries come for Vietnam andsome from India (I believe). Much better quality than the Chinese junk.
I've had good results with all my Samsung batteries including multiple pairs of Buds, the exception was that one failure. It had a rough ride as I live in the desert. A few low temperature charges may have sealed its fate. I always fast charge but generally use a 40-80% cycle with a temperature limit of 72F to a max of 102F. I consider Li's an expendable asset, which they are. So with the high hours I have on this heavy used N10+, 2 batteries so far isn't bad. My other 2 Samsung a S4+ and a flip top still work. They had their batteries replaced years ago due lose of capacity not failure.
You never know but more than likely the guy with all the busted batteries unwittingly did something stupid, again and again or had ulterior motives. I don't buy that battery doom story. If the Li's aren't ever replaced they are likely to fail eventually. They start to degrade the day they're assembled.

Well, i do have terrible luck after all, maybe the battery inside my phone is the exception rather than the rule, it's probably just one of the few defective units out there i really can't find any explanation to this, i'm quite used to solving problems, but i'm still scratching my head because of that one issue, i think i'll try toRMA, and if that doesn't work, i'll get a battery replacement.

General Excessive battery drain

I have all the bells and whistles turned off, uninstalled a ton of bloatware via ADB commands, and everything's been fine - great battery life. But then I charged up to 100% last night and when I awoke it was at 80%, then by 12 noon i was at 64% and this was with battery saver turned on. I checked battery usage and nothing was amiss. I don't get it, how is my battery draining so fast when I'm not even using it? There wasn't any firmware update, so I'm at a loss as to what the issue is.
So I reset the phone and set it up again, charged it back to 100%, then lost 4% in 90 minutes without even touching it. I'm guessing it's a hardware/battery problem.
Anyone else having this issue?

Try temporarily disabling Google play Services.
Google backup Transport and Playstore are dependencies of it. Backup Transport can do this. Normally I keep Play Services disabled unless I need it.

I've just charged to 100%, heading to bed. If I wake up and I have excessive drain again, I'm going to try your suggestion. Thanks for the tip!

Well still had huge battery drain with play services disabled. I factory reset yet again, removed all the bloatware I could, yet a charge to 100% is down to 94% after 2 hours of just sitting on table. I got a lemon. This is a straight talk pre-pay phone, so I'm not sure what to do next.

Disabling Google play Services may not fully stop the Backup Transport drain....
You need to find the apps causing the power drain, this is common on Samsung's.
Disable adaptive battery and the other power management junk*.
Factory resets are generally worthless; you need to find the root causes!!!
Disable only apps that are proven power hogs or are just to terrible to look at like Digital Wellbeing. If you disable a service needed by an app it may constantly keep polling for it. Use discression on what is removed.
Install a logging firewall if you can or otherwise see what apps are using bandwidth. Kill by altering their settings ie no background data/battery.
All cloud apps will likely be hogs. Social media apps shouldn't be on the device. Activate Developer options and use its tools. Use the tools in Device Care.
Turn off all Google, Samsung and carrier feedback. Android 12 may give tracking tools as well, I don't run anything higher than 10.

For logging firewall, there's this one I'm using nowadays. Show you how many requests all your apps do (spoiler : it's a lot)

I have no idea what im looking at with that app. I'm losing 2% battery per hour overnight with it sitting on my nightstand. The only things i see being used is "google play store" , " play services". "netd" & weather. I don't see anything out of the ordinary.
I did a factory reset yesterday, removed all the bloat (disabled or uninstalled) everything not needed that the phone would let me. I used ADB to set RAM + to zero only. This drain started 2 days ago and there's been no updates so I'm at a loss & actually think its a hardware problem. Phone is only 3 weeks old. I contacted Straight talk and they said I have send phone in and they'll send me a used one once they get it. I'm pissed.

I hope you are aware of the risks with uninstalling "bloatware" with ADB. This may result in problems. Return the phone to default (factory reset) to get all back and only remove stuff you can without using ADB.

You can temporarily screw up the OS but nothing that can't be reversed it with a factory data reset, which I did. Anyway, it was fine. Let's just say I may have dropped it from waist height and that's when this battery drain came up. I have it in a UAG case and a glass screen protector (I've dropped my iPhone much worse about 50 times and never had an issue). The phone and the case are in mint condition, it shouldn't be malfunctioning from a 3 foot fall on a sheet vinyl floor with a case on it. But it is. Maybe its just my unit, but this is a fragile phone.

If you're in an area with a poor cell signal, your smartphone will try to connect to the nearest cell tower and drain your battery quickly. I thought there was an issue with my Pixel 6 battery but after buying an iPhone 13, I later found out that poor cell signal does drain your battery rather quickly.
Try enabling WiFi Calling and choose WiFi as your preference, then enable Airplane Mode with just WiFi turned on. This is what I do when I'm at home and then turn off Airplane mode when I'm out and about (obviously).

That's not true itself. I'm in a poor cell area and normally only see 4% drain overnight with phones over the years. This is the amount I expect, no more. If any phone ever sees 10% or more overnight then it has a problem either software or hardware.

I've seen this with my last Samsung but 1-3 reboots in a row always fixes it for a week or two. Normally only needs 1 reboot a week. Its in a system installed app or code.
However, battery drains can be caused by literally anything lol. Any app can cause it. Any system app can cause it. Even the OS can cause it. It could be in anything technically.
Batteries can go bad but you'd likely see something else happening if the battery was going bad or if the fall did it. I really don't think that's the issue here but suppose if it is then you have an odd situation where the battery drains from 100% to 0% smoothly.

No, it was dropped from 3 feet onto a sheet vinyl floor, no visible damage but that's when it started. Something internally got messed up. It took a month but Straight Talk sent me a new A53, and no battery drain at all now. Straight Talk is another issue...smh

Oh, I didn't notice the data gap with the last reply just made last week lol.
Really though a phone replacement doesn't mean it wasn't software. I'm an app developer and can't even go simply based on that.
Is it possible to have a smoothly draining battery from a drop? Probably in some rare weirdly odd corner of the universe lol. Maybe you did find the corner.
At least its solved anyway. That's really all that counts.

Yeah, the small drop was definitely the issue; Wi-Fi was not connecting or not staying connected. It wasn't software, I reset the device and same issue. It must've popped Wi-Fi antenna loose or caused a short somewhere. New phone and now I lose 1 - 2% overnight. Now to unlock it from straight Talk.
