Guys...I have been doing some calculations. Here's my screenshot... it says that I'm at 41% down from 85% (I'm using the in-built battery charge limiter). The SOT is at 200 mins. I.E. in 44% of battery usage, I have achieved 200 mins of SOT. So, wouldn't 100 to 0 mean 7.5 hours of SOT...sooo...is the battery life bad? Or are my calculations really off?

looks quite good to me. I went from 85 to 45 with 1hr 38min SOT :ROFLMAO:

I know I'm posting in the wrong place but can someone with the knowledge of modding apks to work with newer android versions fix this live wallpaper. The original cosmic flow wallpaper was modded and works perfectly but is limited to 6 colours. This one I have attached has loads more, @dr.ketan maybe you could help me. ☺️☺️ I'd be forever grateful.

Do you game a lot? My SOT includes normal browsing, emails and whatsapp...So, yes, if I game the battery life will never be like this...
No gaming at all. Just regular stuff. I do use two SIM cards though. Stand-by drain seems to have increased. Overall i feel the Android 11 battery was better.

As far as smoothness goes, overall i think things are much more buttery on Android 12, but there are those random jitters throughout the day that spoil the entire experience. They never completely go away.

I remember it took many months for A11 to reach its peak performance and stability on this phone, so for a first release of A12, it's not that bad and I'm hoping it will improve just like A11 did.

Surprisingly, i haven't faced a single stability or compatibility issue or crash, or any other bug so far except the WhatsApp video green line bug and some random graphic bugs like in the screenshot.

The only issue for me right now is the battery life.

Yes, I think dual-sim does have its disadvantages. Again, I remember when I first got the phone on the release date, the battery drain was horrible but then over the course of 3 or 4 software iterations, the battery became amazing. So, yes, we need to give Android 12 it's time to be stable. Also, I think Android 12 reports battery drain differently compared to A11. In A11, I feel it's something like iOS where you r on 100% for a long time and then drop like a lead ball once it starts ticking down..but in A12, it's more aggressive...

Honestly I installed BUKG from BUK8, but it's not much optimized...nevermind, to be honest it still sucks:

- Battery consumption is still high.
- Some animations glitches are still here and ugly lag, during fast app switching, drive me crazy everytime.
** Some remaining apps (Cloud, Wearable, Email) still have the old overscroll and loading animations.

I hope I don't have to wait for One Ui 4.1 to get something that works well.

Yep it's got to be the software that's causing high battery consumption as my battery health is perfectly fine. Also if you check Gsam battery monitor and android system wakelocks. The camera service is at it still !!!!!

    BULF might be the worst one yet, previous versions had bugs and glitches but 120hz was always smooth for me, but now..

    On BULF it feels like the phone drops to 15hz, never mind 60hz, the slow down and stutter is ridiculous, completely lost the fluidity of my device.

    Good day to you both. Just dropped in for a bit of thread cleaning and a friendly request. Both of you have been excellent and helpful members on XDA for many years now, and for that we are grateful. Having said that, I am politely asking both of you to please end this pointless feud here and now on the public forums. If you wish to malign and prod each other, please do so via PM's since this is not Mega, IG, Twitter or whatever other site you choose to use.

    Please keep this thread on topic, and do not detract further from information that other members are asking and posting about.
    I greatly appreciate your cooperation, and wish everyone a pleasant day. Now back to your normally scheduled programming. (y) :cool:

    Yep your right, im past caring. Might give one plus a go.

    If you want to, that's fine.

    But SPOILER ALERT : you're gonna find issues, if you look for them.

    That's what I'm trying to make you people understand, you overthink all of this. Just use your phone and wait for the devs to update.

    I was just like you, but today I've past this obsession of the efficiency. You are wasting too much time trying to mesure and compare.

    But that's your time, use it the way you want ;-).

    In this thread, you can discuss and share the Mega links of new firmwares (OFFICIAL STOCK) for the Galaxy S21 Ultra 5G!
    NO CUSTOM ROM's and/or ROOT-talk

    How to flash the firmware to your phone:

    Odin.png


    1. Extract (un-rar) the firmware file (i.e. to folder C:\Odin) ***
    2. Download Odin v3.14.4
    3. Extract the Odin ZIP file (i.e. to folder C:\Odin)
    4. Open Odin
    5. Power OFF your S21 Ultra 5G
    6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone. Or use the command "adb reboot-bootloader".
    7. Wait until you get a blue sign in Odin
    8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!
    10. Click the start button, sit back and wait few minutes for the device to automatically restart.

    *** You can always find the LATEST firmware in message #2

    Thread cleaned. Just a friendly reminder to all. While a certain amount of OT discussion is usually always allowed on XDA, that does not condone starting a flame war based on one's
    opinion over another's. So please be respectful to each other, and please keep OT discussion equally respectful. Remember: "If You Can’t Say Something Nice, Don’t Say Anything at All." Is still a good rule to follow. Thank you for your cooperation, and a pleasant day to all.
