Battery calibration HELP

So I love the phone but I just can't stand this battery anymore I'm starting to think t mobile gave me a used battery. Ive tried draining the battery to 0 then charging it to 100 nothing. I tried the restart nothing. I work from 8 to 4 and I start the day with 100 and end with 10 if I'm lucky! As I'm typing this its at 87% and its only 9:04. Running services like app pack car home and such are off wifi is off brightness at 50 and I kill tasks a lot with ATK can someone please give me a step by step on how to calibrate even if I have to mod the phone Thank you =)

I'm having the same issue as well. I just received my phone yesterday and I charged it fully last night and kept it unplugged over night. Overnight it only lost about 3%. But after medium ussage this morning which consisted of checking email/texting/surfing the web, the battery dropped a significant 25% over the course of 40 minutes. Any suggestions?

Root phone if you havent already
Charge phone to 100%
Flash clockworkrecovery
Boot into recovery and under the advanced menu select "Wipe Battery Stats"
Reboot

That kind of behavior is normal. The phone loses very little while idle but checking email and web surfing both require a data connection and that uses a lot of power. More usage = faster battery drain.

My galaxy s would easily last a full day with constant email/text and a couple hours of talk. This phone doesn't even seem to be able to last me a few hours. Do you also experience this significant battery loss?

You prolly need to do a factory reset. For some reason some peoples phones use more power even at idle than they should. My phone was one of them. There is a whole thread about it but pretty much doing a factory reset should correct this issue. Did for me. I get almost twice the battery life of my Galaxy S.

No need to go into recovery to wipe the stats, just use Battery Calibration(requires root) its in the market and also includes instructions on how to use the app.

true story. ive never used it so it didnt come to mind lol.

In the passed hour I've now lost 40%. That can't be right, can it? :/ I'm running everything stock btw and I'm unfamiliar with rooting and things of that nature.

I had the same problem. I followed the thread below and it worked. I've ben getting 10-15 on moderate-heavy use. I also did the htc battery calibration before I ran the battery calibration app. I use juice defender as well.

Check out the link jsauce75 posted. If you are running stock that means you most likely have background services running that are pulling significant battery. You will need to root and then use titanium backup to either remove or freeze those services.
Before doing that thought I would download Battery Monitor Widget. Use it to see how much power (mA) your phone is using. When I first got mine I was draining battery fast and when I used that widget I learned that the phone was using over 100mA even when idle. It was like the phone would never go into a sleep state. After doing a factory reset my phone idles at 1-2mA.
There isnt much you can do about battery drain while you use the phone because the screen and data connection are huge battery drains. All these tips are to improve your power consumption while idling. As I said before all I have done is factory reset and removed unneeded services and I have been getting double the battery life of my Galaxy S with the exact same apps and usage for weeks now.

1) You said you're using ATK "a lot". This is adding fuel to the fire. ATK is not needed with today's android systems. These apps you see sitting in ATK are sitting dormant. It's like the task manager of a computer. I have 3-4 apps running in my system tray and around 20 other services running in my task manager.. They are all sitting dormant, using zero CPU. They have ram allocated to them. That's it. That's the same as the Android. They are sitting dormant, and they have memory allocated to them. The best thing about the android OS is that it will automatically shut down dormant apps on its own. A PC doesn't do that. So, look at it this way. Let's say I'm on my laptop's battery. I have 20 apps/services running, and they are dormant. They are doing nothing towards drainage of my battery. But, I decide to turn on my screen "a lot" during the day, and kill the apps. Boom... Battery usage for the CPU to turn the screen on, the screen takes away from the battery, usage for the task monitor to be running.. Then, there is a process to shut down the apps, that takes battery.. Then on top of all that.. When the apps restart on their own.. guess what, they have CPU/Battery usage. You're adding fuel to the fire.... a lot of it, imho.
2) Install Watchdog and Titanium Backup (pay the small fee so you can freeze the apps.. or you can learn how to manually remove them yourself. I like using the app). Now, just to prove the point.. Open up ATK... Then go into Watchdog.. You'll see the apps that are running in ATK are not using any CPU. But.. when they do start up/shut down, there is some usage going on that will contribute. So with Titanium backup, freeze the apps. The apps I have frozen: AppPack, Broswer (have dolphin installed instead), Car home (2 of them?), com.android.provider. applications, com.logmein.resecuesecurity and .rescue, email (using gmail instead), My account (2 of them?), nfs shift, nova, street view, tmo TV, tegrazone, telenav, videochat voice dialer, zinio reader, zsprovider. From there, you can see the apps running in watchdog and you don't need ATK.. But, watchdog also uses processor to "monitor" the usage of other apps.. So place the threshold setting at like 40%, and the frequency at 3 or 5min. This will keep Watchdog from using too much battery, but it'll also notify you if an app is running wild on cpu usage. Maybe for 1 day, put the threshold at 30% or maybe even 20%.. so you can see if 1 or 2 apps are using a lot of power. If they are system apps or apps you want.. just leave em be. If they are not, freeze them/uninstall them.
3) I have found that using wifi and wifi calling GREATLY increases my battery life. As soon as I turn on 2g/3g/4g... my battery starts to take a fast dive. Whenever possible, use wifi/wifi calling...
4) Screen down to the lowest brightness setting. Shut off screen manually whneever you are done, or set it to 15sec shut off. I only bump up the brightness when i'm outdoors.. The glare makes the low setting impossible to see the screen.
5) Shut off syncing, bluetooth, and gps unless you need it. If you're around a computer at all where you can get your email and such, there is no need to use the phone for it. I only use tmo's network and syncing when I'm away from work or the house... typically when I'm on the road.
Lastly, yes, some people want to use their phone... use the 4g service.. etc. I understand.. But also understand that if you're going to use the phone like a computer.. and you're going to get 8hrs out of the battery... I say that's pretty dam good. This post is not meant to say that there is nothing wrong w/ the battery... It's to help you out to determine if there is a problem in the first place. There was a guy complaining about battery usage left and right. When I got involved in disussions with him, he admitted that he's on his phone all day long... txting quite a bit. Well.. duh?
I don't doubt there could be some challenges with a bad app running wild, a bad battery, etc. But I also don't doubt there are people who are using the crap out of a dual core phone.. and are doing things themselves to add to the problem... and then they blame the phone.
That's my 2c....

Thanks for the great detailed response. The OP actually was the one who stated he uses ATK, I don't. I looked through the thread with the recommendations for 20+ hour battery life and noticed that those apps you mentioned above required rooting the phone. I hate to sound so naive when it comes to this stuff but i'm a fairly new android user and have not yet discovered a lot of the technical aspects behind it all. I'm not exactly sure what rooting is and what it entails. Is it something you suggest I do? Also, my battery is slowly approaching 0%. Should I let it drain all the way before charging it again? Others suggested letting it drain all the way and doing a factory reset and that seemed to help their issues.

By default Android restricts certain areas of the OS from being accessed by third-party applications (prolly for security reasons). Only problem is a lot of great apps require such access to function properly. In order to give them that access you must root the phone.
Here is the rooting thread. It is extremely easy to do.

Does rooting affect warranty in any way?
or the ability to perform a factory reset for that matter?

New to android is not an excuse, I was a religious crackberry user for the last 8 years, and I just switched over to android last month. I'd suggest you to root you phone so that you can remove the stock cr4pwares, and the ability to install custom ROMs. Took me 10 mins to figured out how to install andriod OS into my hd2, 25 mins to perm rooted and unlocked my g2(this beast is little bit more "lockdown" than the other), and 5 mins to rooted the g2x. Google is your friend, bud. If you want something more out of your g2x, use the "search" button. Just my 2 cents.

FYI: I'm a first time android user (smartphone user at that..) and I rooted my phone easily. You can unroot your phone just as easy as you rooted it. It's a 1 click method with that software.. check out the link. Seriously, it's easy.
You may have to have ABD ADB or whatever installed first.. Not sure. I heard about it, and did it... and then rooted.. and it worked.

Thanks for the help guys, appreciate it. I'll let you know how it goes
I'm also having another issue with the phone. I'll see if you guys can help without having to make a new thread.
Yesterday I installed Zedge and downloaded one of the wallpapers there. When I applied the wallpaper I noticed a bit of lag on my home screens, so I reverted back to the default wallpaper and the lag was still there. I deleted the app and wallpaper I downloaded but the lag was still there. I applied a default live wallpaper and the lag disappeared and everything was moving as smoothly as it had been originally, but when I apply the regular wallpaper the lag persists. Any ideas?

now if u do root and remove bloatware what all is safe to remove i have all but my account car home and i think one other can anyone provide a definite list and battery is significantly better after just that

LOL think there's not driver issues. Swapped a dead battery with a fully charges one today and been running almost 2 hours still shows 1%

Losing battery life while phone is idle

Hello everybody, I notice lately my phone is losing about 10 percent battery life every 2 hours while it is idle. The funny thing is I have data off no text message and made one phone call. I don’t know what’s going on. I am running stock.

The Newest apps I downloaded were comicbook reader, Spotify and Netflix, but that shouldn’t matter right? Because my mobile data is off

that sounds about average to me. since its stock, i would just put Juice Defender on it and leave it set to "balanced", then see where youre at battery wise.
additionally, you could try Watchdog to see if theres any background apps that are consuming a ton of cpu(it can happen)

do you ever charge your phone in your car?
i know when you charge it via a wall charger or your PC, there's overcharge protection so realistically you can leave it "plugged in" as long as you'd like.
apparently though, if it gets fully charged and you still leave it plugged in in your car it can eventually do some damage to the battery and eventually kill it.
i had that happen to my old Galaxy S 4G & when i went to get a new battery they confirmed that that was the culprit.

You need to go into settings/ power/ and uncheck fast reboot . It runs all the time and eats up battery.

phone idle isnt as important as the time it says it's without a signal. if you arent getting a signal, it's looking for one and really really draining the battery

Yep TWS is the biggest culprit of battery drainage on these Android phones. If you're in a poor reception area, you're SOL because the phone will eat through the battery searching for a signal. I have an Epic and have similar battery drain issues due to this.

First, you should seriously consider rooting, then flash a custom rom & kernel. The stock rom is no battery sipper, and custom roms & kernels are much more efficient. I was getting ridiculous overnight drain (>20%) on stock, but now I'm getting only 1% per hour (6-8%). Also, grab Autostarts from the market. It prevents unnecessary apps from launching in the background & wasting battery (& memory)

It'll show in the about stats when you press on the phone usage stats how long it was without a signal if you want to look (in case you weren't aware). Also I would make sure your phone is set to use wifi when sleeping always and not mobile (under wifi settings → press menu → go to advanced).

My mobile data off when I'm at work. So pulled my phone off at 6 am, made one call, checked my email and now I'm down to 93 percent. This is just ridiculous seems like my battery getting worst by the day.

I'm at home now on WiFi...my mobile data is usually off all day at work. Watch dog only alerted me to dolphin browser and I always close that out when I'm finished. I don't know what's going on.

Why do I need to baby sit my phone to get good battery life?

This is not correct. The battery charge is controlled by the phone itself. the battery also has some electronics in it to limit the charge. The car charger provides 5 volts just like any USB port. You can (and I have) leave phone plugged into a car charger with no issues.
It is true that you should avoid charging the phone when it is HOT. So leaving it in a HOT car or any place HOT is a bad idea.

Checked the settings and my phone is using 3% battery life while it is idle. So I shouldn't be losing so much power. Is my battery damaged?

Yep, backing this guy up. The battery has it built in where it'll cut off the charge after it's full- and android has it that after it reaches 100% it'll let it drain down to ~90% because keeping it at 100% for extended periods of time is bad for the battery health.
For those more interested in your phone's battery and how charging works, check out this post:

If you're losing battery life when you're idle you have a few main reasons.
- First check to make sure you have a low min. set for your CPU, you don't want to have your CPU rev'd all the way up all the time- it's just not good.
- Download "spare parts" and check under "battery history" and you'll be able to see if you have a lot of GPS usage, data usage, CPU usage, etc.
- I'm not sure if mobile data turns both 4G and 3G off. I know the 4G here totally demolishes the battery, even more if you don't have it in your area.
If you don't have 4G and would like to save your battery from a painful death, do this (easy to change back)
*#*#4636#*#* -- Go to "Phone Settings" >> change to "CDMA auto (PRL)"
This will turn off 4G and stop it from searching, while still allowing you to use 3G and not have to turn off all data.
Hope at least one of those points helped you out and hope you get some better life because that's pretty bad, shouldn't be normal.

Losing 5%/hour is normal for my phone when it's sitting doing nothing. The battery is a joke. I have Juice Defender Ultimate and that brings it down to maybe 2-3%/hour.

Battery Drains After Crash

My phone has been acting really weird the last few day. I had [ROM][MTD]CyanogenMod 9.0.0-rc2 UNOFFICIAL by TeamAcid[R5][Jul-20-2012 installed on my phone. But it would crash all of the time. Afterwards when the phone rebooted the battery would go from 100% to 9%. If I dont boot the phone back up right after a crash and wait a little while. When I boot it up the battery will be around 40-45%. I used [Heimdall][One-Click] The T959V Heimdall One-Click Collection [05/20/2012] earlier today, Just to see if I continued to have the battery problem. I only had the phone crash once while on the stock rom, and the battery did drain about 50% but I also started having a problem where I would lose my data connection all together. Rebooting the phone brought it back, only to lose it again after around 30min to 1hr. It has not crashed for about 3hrs now and I have not lost my data connection either. Anyone have any ideas what might be going on here? I tried deleting the battery stats with the battery at 100% before going back to stock but that did not seem to help at all. I downloaded a batter calibrator from the market place and tried that as well. Used it when the battery was at 100%. None of this has worked. Now that im back on the stock rom its only crashed once, but the battery did still drain. Any ideas? I would really like to go back to CyanogenMod 9 but its not worth it if the phone continuously crashes and kills the battery. Any help would be greatly appreciated.

Try Gremlins Remover.
sent from me

So you don't waste any more time, "battery calibration" is snake oil, lithium ion batteries don't need "conditioning" (and actually suffer from both high temperatures and deep discharge cycles), but the moon is made of cheese. Ok, at least the first two are true.
As you're having problems with one of the most stable and reliable GB ROMs for this phone, I suspect that you may have one or more of:
Bad battery
Bad user-land applications
Corrupt application data
Corrupt media data (for example, music on your microSD)
Bad phone
Bad luck
A "start over" approach with a complete clean-out either using the above-mentioned one-click, or doing the equivalent by hand (wiping all partitions, flashing stock, starting with a fresh microSD), then seeing how the phone/battery behaves without any apps would be the path I would take. If it passed that, I'd slowly start adding back apps, and only restoring data/preferences where you really need them.

Im doing the gremlin remover right now. I will let you guys know how to goes. Thanks for the advise, this has been driving me crazy.

Tried the gremlin remover last night and played with my phone today. Its still crashing and then when I boot it up back the battery is pretty much dead... I think i have a bad battery. Never had these problems with the phone before. Thanks for the help guys. I guess Ill get a new battery and see if that fixes the problem.

I have this EXACT same problem. I'm on AOKP and the battery with go from having a decent charge and die. Then if I take the batt out, hold the power button for 15 secs and let the phone sit with no batt for 10 minutes or so, the phone will go back to around 50% batt life. After gremlin remover and Bryan's one click back to stock multiple times, I've finally come to the conclusion that I need a new battery.

I ordered a new battery today. I will let you know how it goes.

Mine does the same thing... doesn't really crash often.. once in a blue moon. But if I reboot. . I get that instant battery drain ...GR didn't fix it.... I just attribute it to ageing battery.
Sent from my SGH-T959V using xda app-developers app

So I looked I to this issue more. For anyone having this problem, remove the battery and place it on a hard flat surface to see if it has swollen any, if it has then the battery is defective. My battery actually rocks a little. I could actually tell it had swollen before I even put it on my desk.

That is only for seeing whether a cell has busted. It is normal wear and tear. That is kind of like how u lose battery life after hundreds of cycles because it is just how the current li-ion battery technologies work.
I would download the one click and also reflash boot loaders and repartition your device.
Sent from my SGH-T959V using xda premium

Tried that, even with bootloaders. OP also stated they used gremlin remover as well. As we we're both having the exact same problem, I was giving him a better solution that wasn't the standard "reflash, repartition, etc."

I finally got my new battery in. And all is well now. Thanks everyone for the advice and help

thats crazy swapping you battery worked. lol, mine does it too. not so much the crashing just a simple reboot and it will be drop down from 70% to 1%. This was doing the same thing with my phone before my charging port got busted. So i had to swap out the guts from my old galaxy s with broken screen. When i put the new internals in i started with bh's one click back to stock and flashed antonx kernal. Then flashed cm9 and it still does it. i will try a new battery as well.

My thought (AFTER being solved)
Well, I don't mean to come off as rude, but come on guys! I've had this problem for a while, and as soon as it happened I knew I needed a new battery. On top of my phone being somewhat "old", the fact we all play around with it so much, and do so many battery pulls most likely does NOT help the matter. At least I screw around with my phone and try out many ROMs...
But I'm glad I have confirmation that a battery swap will do the trick. It sucks that stores don't carry the t959v battery anymore... Guess I'll be ordering online tonight.

[Q] How to increase battery life?

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?

Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn

ahh ok thanks guys ill do what you guys said and see if it helps

you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.

no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Download Gemini from the play store and manage the autorun for apps. That's what I do and it saves quite a bit of battery

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.

If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.

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.
