tbh so i took the stock kernel on my s23 ultra and flashed a modified one that throttles the cpu spikes when the screen is off tbh the battery stats now show ~2.8 days standby vs 2 days before

key changes:

• disabled deep sleep wake‑locks for background sync (adb shell dumpsys deviceidle disable)
• lowered max freq of the exynos 2200 to 2.2ghz when screen off (set via /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq)
• patched the power HAL to ignore wakelocks from com.google.android.gms (biggest drain)

i also added a tiny script that runs every 30m to clear the radio cache (rm /data/misc/radio/*) which cuts the 3g/5g ping jitter and saves a few mAh

anyone else tried similar tweaks? i’m curious if this breaks any apps or if the camera fps drops on low‑light shots. drop your thoughts, i’ll keep tweaking based on feedback lol

i've had my s23 ultra for like a month and the 5000mAh battery is already a joke tbh. i charge it to 100% and within 2 hrs i'm at 40% and the UI shows background apps like samsung daily board and some random adware hogging cpu. i disabled adaptive battery but still the drain is insane. i switched to a 45w charger and it still heats up like a toaster. i thought the exynos 2200 would be efficient but it's just a power hog. i even tried a custom kernel to trim the bloat, no luck. why does samsung keep pushing this nonsense when the iphone 15 pro barely drops below 80% after a full day? i need validation that i'm not the only one dealing with this garbage, and maybe some tips to actually fix it without rooting the whole thing. rn i’m considering dumping it for a pixel 8 pro because at least that thing respects my battery lol.
