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.

    I am getting almost 12 hours SoT on 23+ now lmao. Like you, my battery was draining at like 10-12@, now its like 5-6 an hour, crazy. I checked, after 5 hours of usage I was at 74 percent. (Mixed usage)

        Keep in mind i am 90% on Wifi Dark mode, light profile, adaptive battery off etc. I was getting better battery life than you even on UI 5 lol, but it also strongly depends what you use, do you game etc. I have discharged the phone exactly 18 hours ago and am now at 54%.

                I was the same. Look, if the battery lasts you 24 hours and more without charging, and you dont game all day - its good. Its nice not to have to worry much about the charge, compared to having to charge like twice a day. Its good, worry not.

    I started my day at 7AM woke up (my phone was 85%), and turned my music on (youtube music) then at 8AM got ready for breakfast watched the rookie on my phone (tv show) now im getting ready to do some grocery shopping and my phone is 60%

    Specs: S23U Wifi and 5G are always enabled (developers settings) Bluetooth always on. Max screen resolution and and full refresh rate.

    Usually my phone would be at 70% or even 60% I like this new battery optimization.

    I have base S23 and really concerned with my battery backup. I might be on heavy usage but I have enabled light profile but still on 120hz refresh rate and mostly on wifi. Still I am hardly getting 4 hrs of sot. I had read about some reddit post mentioning about the initial data transfer technique used might cause this issue. Anybody has any idea about it? How can I improve my sot? Daily usage: Instagram majorly and routine apps PS: I charge till 85 only.

      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 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.

        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’ve noticed quite a dramatic difference too on my S23U! It seems significantly better

    That is pretty impressive. I thought 7 hours on my Galaxy Note9 at max brightness was good. Still is good IMO, but the more battery life, the better. What brightness level do you have your phone set to?

    I didn’t do the update yet because I was waiting for battery reviews. It conforts me, you are not the first one to say that the battery has improved!
