Question How's the battery life & SOT after weeks of usage? [S21 FE Snapdragon ver.]

[szerwony]

How do you all get those crazy long work times? I have S21 FE Snapdragon since 2 weeks. AoD is turned on at day and screen has adaptive refreshrate with Galaxy MaxHZ app. The best I can do is 2-3h SOT and after 24h phone needs charging.

Every app I don't use I have put to deep sleep. I have about 84 apps that are permanently shut off which contributes to the SOT. Also, I never fast charge, 5G is always off and dark mode is always on.

Cell reception.
snap888 is made by samsung, it's still crappy, but less than exynos

I have this phone and the battery is okay. If you're on wifi it is amazing but you use any data it drains a lot faster. I'd get like 4-6 hours of SOT on data and 6- even 10 hours of SOT on wifi!

On my S21 FE the battery drains very fast, even though it's connected to wifi (as opposed to 5G or LTE) most of the time, and almost all apps are on battery "restricted" mode and "background data usage" is turned off (and I had to manually go through each app to toggle those settings). This is in additon to the touch response (or lack thereof) glitches.

Does anyone have a Snapdragon variant of the S21 FE? I have it and the battery is horrendous. I've been tweaking many settings from simple battery settings, all the way into developer settings. There's been very little change in performance throughout my testing. A friend of mine on Twitter found a way to combat this issue but when I alter my settings to match his, it doesn't improve nearly as much as his did. He can get over 7 hours of SOT compared to the previous 4_5 we would both get. We also have similar scenarios in which we use mostly Wi-Fi compared to data (and 5G). I really hope future patches fix this. The January patch came in just after a week from getting One UI 5. You can tell the update was rushed as there's many new bugs. When selecting something like files or images, the checkmark just disappears. When connecting to a Bluetooth device, it will try and try for as long as the phone runs. Every now and then the fingerprint activation animation will freeze. Yeah... Samsung has a lot to fix, hopefully it is all fixed and more with One UI 5.1, when the S21 FE gets it. (Thx for reading, this is so damn long...)

It seems today I have different results. I had a 100% charge yesterday morning. So, today at 10 AM I have 13 % left. During nighttime, it uses about 4% without turning on airplane mode.














































Do you have snapdragon variant phone and using it with which carrier sim I can see 4G+ on my phone

 

[Randi03]

Snapdragon with 4G+.

I have an A53 that has great battery life, and compared to that phone the S21 FE isn't that much far off (Both are on Android 13). I'm not a huge power user so the S21 FE can easily last me 3 days or more. I do have the refresh rate set to 60...120 looks amazing, but not worth the battery drain to me. Plus, I have it heavily debloated with Univeral Android Debloater. I love the phone, it's fast and no issues with battery life at all. I always have Wi-Fi, mobile data & battery saver on, & Bluetooth and NFC off. Overnight idle drain is between 2-4%.
