[Samsung Galaxy S21 Ultra] blackhawk:
Even that won't save you if it's running hot... plus it takes up a lot of space.

Larger batteries also make thermal runaways much more exciting.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Have you seen this guy: https://root-nation.com/en/gadgets-en/smartphones-en/en-samsung-galaxy-a72-review/ -- 7000mAh battery!

Big battery = better phone.

That is not too big and thermal runaways are not a problem anymore, especially when the system can easily down-throttle to manage that.

I have turned off any and all power management on my S21U and I don't witness any noticeable battery drain.

I do keep Power Saving mode ON for when I don't use the phone much. It's nice to have that bit of control.
[Samsung Galaxy S21 Ultra] blackhawk:
Thermal runaways ie "events" are always possible especially if Li plating is present. I just replaced my 10+ battery that failed. It was swelling. I was fortunate it didn't damage the display...

Larger battery though means you can more effectively use partial midrange charging to prolong battery life. However I can tell you there's no extra room in the 10+ and to make it thicker for a larger battery wouldn't have been worth the added bulk.

What's needed is the denser energy of the newer generation of Li's; same space, more mAh.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Exactly. And, we need non-root access to limit charging percentage and bypass the battery when plugged in.

Where are these mythical creatures in everyday phones?

Has Li battery technology even improved/changed in the past 10 years? Not that I can notice.
[Samsung Galaxy S21 Ultra] blackhawk:
Doubt you'll see the bypass and that would probably lead to more busted ports.

$1G+ should have more robust charging options no doubt.

Not sure as I haven't look into the Li variants especially if I don't owe or plan on buying them.

They probably wouldn't be compatible with existing phone if they fit because of cell voltage and charging parameter differences.

The bag Li's used in phones are strange critters. Autopsy one sometime and see for yourself. You won't be as comfortable or confident in them afterwards...
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
I can't tell much from these photos.

Has it just swollen up?

If so, did you expose the device to high temperatures combined with a high state of charge (close to 100%)?
[Samsung Galaxy S21 Ultra] blackhawk:
That another one. The one shown is a normal one at the end of it's service life.

What you see there is surrounded by a 8 mil or so bag that's hopefully completely sealed.

The failed one had been losing capacity gradually. One night I slow charged to 100% at about 50°F. From that moment on it would fast charge erratically. It wasn't until over a month later I found the damage (it lives in a case).

It didn't leak. Unfortunately due to a mixup I didn't get the original back. I think it only out gassed but no way to know without a autopsy.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
I only use a 5W charger and avoid going to 100% unless absolutely needed.

Typically stick in the 30-80% range.
[Samsung Galaxy S21 Ultra] blackhawk:
That's a good range. My battery lasted almost 1.5 years under heavy daily usage. Because I'm in the desert it is hard to always protect it from heat. I used fast charging for nearly 75% of the charging as well usually in midrange 20-30% partial charges.

So while I didn't get 2 years out of it, I did get it replaced without damage.

The 10+'s battery is supposedly a hard one to replace, but after watching and learning a few tricks I know I can do it. The adhesive (not hot glue) can be weaken with small amounts of anhydrous isopropyl alcohol safely. Some heat is also used to weaken the rear cover adhesive/seal bond. Easy does it.

With the battery directly on the display, a little isopropyl alcohol and gentle prying gets it done.

Also get the OEM seal/adhesive if at all possible for easy reassembly.

Going forward battery changes will be a cake walk. Better to replace then too soon then too late!

Battery conservation is more a game than a necessity but partial midrange fast charging fits well with my usage. I try to limit cold start temp and maximum temperature. Failure to do either increases the chances of an outright battery failure. Aging Li's are more susceptible... as I have learned🤣
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Yeah, doing 30-80% (or an even smaller range) with fast-charging each time would easily give you a comfortable 4 years of battery-life.

I don't bother with battery replacements.

Battery replacements are now $60-100 thanks to Apple and BatteriesPlus and UBreakiFix.
[Samsung Galaxy S21 Ultra] blackhawk:
On a 10+ the tools you needs less the heat gun are about $30 and parts are cheap, another $20 or so. Small shops will do for $50 but I trust my skill more... now.

You -might- get 4 years but with a phone worth $600 in good condition replacing the battery is a no brainer. The C port pcb is only $20 too. Glass rear covers are under $20 if you accidentally break one.

As the battery degrades past 80% of its original capacity it's best to replace it.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Yes, because internal-resistance and other factors will make it so that whenever there is a jump in power-consumption by the device: boom, shut-down.

This is why the low-power-mode (70% CPU limit) may help over time and as the battery ages.
[Samsung Galaxy S21 Ultra] blackhawk:
On the 10+ low power mode is a nightmare; it alters the homepage layout forcing you to reconfigure it back once you reset to Optimize mode. It's easiest just to leave it in the Optimized power setting🤣 I average about 7-10% @hr SOT as such.

With Androids once you have a fast, stable platform that does what you want, updates especially OS "upgrades" are a bad plan. The security risks are almost nonexistent if you don't make stupid mistakes. A factory reset* is about the worst that can happen anyway. In over 6 years, much of that on outdated OS versions I never had to do a factory reset due to malware.

There's a steep learning and optimizing curve with Androids to get them dialed in well. More bang for the buck not to take everything that Gookill says you need... you don't.

With Android you decide what OS version to run.

*always be ready to do a factory reset though Android crashes are very rare they do happen. Having a full plan, complete redundant backups minimize the time, and prevent data/sanity loss.

A SD card slot allows for a data drive so you don't need to reload 100's of gb of data after a factory reset.

An installable copy of all apps and updates can be stored there as well. Simply backup the SD card then for total data redundantcy. Sweet.
[Samsung Galaxy S21 Ultra] Limeybastard:
Lets be brutally honest and take one look in the mirror, anyone who spends over 1k on a mobile device has some bolts loose in the northern territories . Myself including. Back on subject, delayed notifications isn't something new on android devices. Welcome to Android 8. Plenty of fixes for it, without the need to use ADB LOLzz
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
I never had this issue until Android 11.
[Samsung Galaxy S21 Ultra] blackhawk:
Same maniacs that ran XPx64, refuse to leave W7 and built their own PCs, no doubt.

My first mobile Motorola phone had a similar price tag with a really cool red LED readout.

We've been conditioned to reach for the fruit at the top rather than the low hanging stuff🤣

Android 8 has some vulnerabilities that 9 doesn't have, like that nasty rootkit that requires a reflash to kill.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
I'd love to hear this fix for GMail notifications.

[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Doesn't justify Google's failings with Doze killing our notiifications here.
[Samsung Galaxy S21 Ultra] dovahkiin4756:
Using Outlook is the only fix I found.

The app allows Gmail accounts and notifications are instant (at least on my phone).

Thanks for the adb tip, though.
[Samsung Galaxy S21 Ultra] blackhawk:
Outlook, destroyer of worlds.

Outlook was never secure🤣

It's always been a nesting place for malware.

Keep all email in the cloud; download attachments, jpegs, etc only when needed.

Gmail is bulletproof when used correctly.

In over 14 years of use it's never been responsible for a malware infection on any of my PCs or Androids. That's impressive to me.

If you're really antsy you can always manually refresh Gmail. I use manual sync only... just not in a hurry.
[Samsung Galaxy S21 Ultra] felloffthetruck:
Yes, please let us in on the fix for the notification problems?
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
This isn't 2005.
[Samsung Galaxy S21 Ultra] blackhawk:
Doesn't matter. Keep it in the clouds or suffer.

Tell me when you get nailed🤣
[Samsung Galaxy S21 Ultra] Dizzyrul3z:
Edit and deleted.
[Samsung Galaxy S21 Ultra] KingFatty:
I don't understand. Why did you post the screenshot. Does it somehow demonstrate a delay or non-receipt of your notifications?
[Samsung Galaxy S21 Ultra] Dizzyrul3z:
Sory i made mistake in posts.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
I do keep my mail in the cloud.

But, as far as Outlook being bad is concerned: it isn't bad these days.
[Samsung Galaxy S21 Ultra] blackhawk:
It's reputation precedes it.

My PCs are all off the internet now. This also allows W7 to run with impunity. Been over 6 years since I had any type of malware on them.

Androids stand up much better. With phones like the 10+ the PCs are mostly for data management or photo editing for me now.
[Samsung Galaxy S21 Ultra] Pojosamaneo:
From the bottom of my heart, thank you. Saved me from buying another phone on short notice.

I'll keep an eye on this issue for my next phone, or the next android update on this phone. I will not buy another phone that has this problem, especially one that retails for over $1,000.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Truly ridiculous. I don't think it's a Samsung issue though. I think it has to do with Android 10 or 11.

And, now even iPhone people are reporting notification problems.

What a disservice!
[Samsung Galaxy S21 Ultra] amwbt:
I have had both iPhone and android together for about 5 years or so. As I am a tech guy I often carry both (mainly cause I can’t get my android notifications timely). I can tell you since android 9 there has always been an issue with delayed notifications. Does not matter the android phone. I’ve had pixels 1-4XL, Samsung notes, OnePlus 7 Pro and 8 Pro, and I now have Galaxy S21 Ultra, along with iPhone 12 Pro Max. I cannot rock android as my daily driver (which I much rather do) because I may not get some very important notifications until I unlock my screen. I have tried every trick in the book. There is no way around it. Besides the trick posted here. Again, I’m very disappointed cause I’d rather rock android as my end all be all.
[Samsung Galaxy S21 Ultra] amwbt:
There is an app in the App Store called LADB. It allows you to run ADB commands from your phone. You can google how to use it. It’s still not automatic but if you do have to reboot your phone and don’t have a computer handy (you have to be on wifi or it won’t work!!!) but you are on wifi this app will allow you to run the ADB command right on the phone via wireless ADB. https://xdaforums.com/t/say-hello-t...l-without-needing-root-or-a-computer.4204855/
[Samsung Galaxy S21 Ultra] amwbt:
Of course the other workaround is rooting the device. Then you can make a script that runs at boot to trigger the ADB commands automatically.
[Samsung Galaxy S21 Ultra] Pojosamaneo:
Does anyone know if this fix works with Android 12 on the S21 Ultra?

It has been working great on 11.
[Samsung Galaxy S21 Ultra] amwbt:
I'm on Android 12 beta for the Samsung Galaxy s21 ultra right now works fine.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
Wait, so you're saying that the notifications work fine WITHOUT any adb modifications?
[Samsung Galaxy S21 Ultra] amwbt:
They asked if this ADB command worked on Android 12 beta I said yes.
[Samsung Galaxy S21 Ultra] lywyn:
Same for me, open laptop working at home and the phone pings an email notification before Gmail in the browser shows it. I would say almost all my emails appear on the phone within a minute or less from send time. My son has notification delays on his Pixel device from Gmail but I think that has to do with him permanently on power save mode to get more use of a full charge.
[Samsung Galaxy S21 Ultra] nixnixnixnix4:
I see your point.
[Samsung Galaxy S21 Ultra] resarfekim:
This is a pretty old thread, but I come back to it every time I restart my Pixel 6.

An example of this: I get an alert when my garage door opens/closes. Sometimes I'll get an alert 20-30 minutes after the door closes. But if my phone is unlocked, the alert comes through right away.

Thanks for providing this solution.
[Xiaomi Mi 11] iamrance.asa:
WARNING: DO NOT ATTEMPT TO USE THE BOOT.IMG ON ANY DEVICE OR FIRMWARE VERSION EXCEPT THE ONE STATED!!! IT WILL MOST LIKELY RESULT IN A SOFT BRICK/BOOTLOOP!

Hello everyone,

Today my Xiaomi Mi 11 received its MIUI 12.5 OTA update. I snagged the OTA update and extracted the boot.img from the payload.bin. Thought I would save you all some trouble since the Rom can currently not be downloaded online (c.miui, etc). If you need any of the other files, let me know. I already have 12.5.1.0 installed on mine with Magisk working. :)

Device: Xiaomi Mi 11 (VENUS)

MIUI: 12.5.1.0 (RKBMIXM) - Global Rom

If you need it for a different xiaomi device/variant:

Snagging the OTA

Start update in Updater.

Use a file explorer and go to the "Download" folder. There should be a folder named "downloaded_rom" go into it.

Wait for OTA to download, it will start the "updating" phase and will say "updating" instead of "downloading." Copy the zip that is in the "downloaded_rom" folder somewhere else.

Now you have the OTA rom.

** This has to be done during the updating phase since the folder is deleted, otherwise.

Extracting the boot.img

Copy rom zip to a PC (Windows)

Extract .zip

Download and Extract the Payload Dumper Tool from here: Payload Dumper Tool (make sure you have Python Installed)

Copy the Payload.Bin and Payload.Properties files to the extracted payload dumper tool folder.

Click Shift+Right-Click in the folder with Payload_Dumper.py file and the Payload files in it. Select the option to open Powershell

Type "python -m pip install protobuf" and hit enter. Let it install.

Type "python payload_dumper.py payload.bin" and hit enter.

Now you should have the boot.img file.
[Xiaomi Mi 11] g0mes1:
Works with version EEA?
[Xiaomi Mi 11] iamrance.asa:
It's not pulled from it but if you want to try, you can use "fastboot boot " then the location of where you downloaded the boot.img. If it doesn't work, then you can just restart the phone and it will boot with the oem boot.img. If it does work, then you should patch it in magisk and use the "fastboot boot" command with the patched img, then "direct install" with magisk manager. That's the safest method to use it on the EEA ROM since this is from the Global ROM.
[Xiaomi Mi 11] rippledrums:
Hi,

Where did you find the OTA update file?

Want to update my EEA but need the boot.img to patch with Magisk after updating.

Thanks in advance!
[Xiaomi Mi 11] iamrance.asa:
When you download in Updater, it is stored in /sdcard/download/downloaded_rom but it deletes itself so you'll need to grab it while it's in the updating phase.
[Xiaomi Mi 11] Sld_Ultra:
No matter what I do, I just get this error :

payload_dumper\payload_dumper.py", line 86, in <module>

assert op.type in (op.REPLACE, op.REPLACE_BZ, op.REPLACE_XZ), \

AssertionError: unsupported op

Even tried doing the extraction on my phone using Termux and get the same error. I'm trying to extract boot.img from EEA 12.5.1.0.RKBEUXM OTA ROM.
[Xiaomi Mi 11] iamrance.asa:
That is referring to the type of compression so it could be a number of things. If you have python3 installed (and working), then check the your payload.bin to see if it's healthy (should be around 3GB in size). I wouldn't imagine they'd use a different compression type on it.
[Xiaomi Mi 11] Sld_Ultra:
Around 3GB?! Okay, you meant extract the boot.img from a full OTA ROM of 12.5.1.0.RKBEUXM. I was using the OTA incremental ROM which is 656MB in size, which I copied from the download folder during it's update phase.

The zip file name was "miui-blockota-venus_eea_global-V12.0.13.0.RKBEUXM-V12.5.1.0.RKBEUXM-9a04415c08-11.0", that I was using. But the full OTA ROM I find for 12.5.1.0.RKBEUXM is stable beta, ctsprofile for safetynet won't pass so I installed the safetynet fix module in magisk. The magisk props module wouldn't work.
[Xiaomi Mi 11] iamrance.asa:
Oh. This is how large the 12.5.1 update was on my phone when I updated with updater. I just pulled it from the downloaded_rom folder from the official update. The payload.bin on it is 3.03GB. I did this because the stable 12.5.1 ROM isn't available online yet.
[Xiaomi Mi 11] AniTigerRu:
What should I do, if my device is Poco F2 Pro?
[Xiaomi Mi 11] iamrance.asa:
Snagging the OTA and unloading the bin should be the same for the Poco F2 Pro. That's if you have a new OTA that isn't available in a full zip yet.

You can check here for full official ROM downloads if it is available. Just make sure you use the right variant if your bootloader isn't unlocked.
[Xiaomi Mi 11] Sage:
Hope some people smarter than me use this as a method of developing some Custom ROMs for our device :)
