Conditions: S23 Ultra - WiFi (some mobile connection), Full Res, full refresh rate, running AndroidAPS in background all the time (custom app for diabetes management)

So on Android 13 I was getting about 1 hour SOT for each 11-12% battery used. On A14 I’m now getting 1.5 hours for every 9%.

Yesterday I had 6.5 hours SOT and had 63% battery left before bed. I did wirelessly charge in the car for about 20 mins though.

Honestly I didn’t think this phone could amaze me anymore - as usual, I was wrong.

    Guys!
    I got a new S23 Ultra (8 GB Variant) and purchased an official Samsung 2 months ago with a 45W charger and used in-box cable with it. I was constantly getting only 3 Hour of SOT. I tried every setting but nothing was improving the battery time. Read every Reddit chat. It was so disappointing. Every Youtuber was praising it to be a BATTERY KING and I was literally getting a battery life of a 3 year old smartphone. Then:

    I started using a wireless charger (15W | random Chinese brand) and my SOT went up to 6 hours now.

    Seems like a heaven now. Even though it is below the acclaimed ideal SOT of 7 or 9 hours but 6 hour is fine too.

    I guess the slow charge is causing less heat and more stable charge in the battery (somehow) but it is working fine. Please give it a try and report your findings too.

    Rest of the settings are:

    - 120 Hz display (obviously)
    - Performance profile on more battery

    - Deep sleep for all random unused Apps.

      I must say, I want to try this. I am getting 4-5hrs SOT currently with location always on, WiFI > 20 hrs, 4G+ mobile data otherwise, dark mode, adaptive battery, adaptive power saver, 120Hz, FHD+ resolution) I have noticed some day it goes to 6hrs. I use two chargers, 45W one by Samsung and a 22.5 Xiaomi charger. I didn’t correlate this until I read your comment. Let me monitor this and update here if charging speed really makes so much of a difference.

      I have experienced similar thing by deactivating fast charging option. I charge my phone on normal mode when I charge it overnight. And whenever I had to charge it again during the day I choose fast charging. Battery discharge is faster when I use this option. Got your point. I’ll try with wireless charger and see if I can get more battery than what I get while normal charging through adapter.
