In Redmi phones, balancing the processor frequency, closing unnecessary background apps, and clearing system cache with lightweight cleaning tools usually works well. To extend battery life, smartly adjusting screen brightness, using low power mode on a schedule, and disabling unnecessary sensors are good approaches. You guys, what settings do you prefer on these devices? Any experiences with custom kernels or ROMs? Would love to hear your thoughts 😊
Ways to maximize system performance on Redmi series phones

Hey man, how much does increasing the CPU frequency in a custom kernel affect battery life? Any experiences to share?
Yeah bro, I also increased the CPU frequency to 2.2 GHz using MIUI's developer options, disabled unnecessary preloads, and froze background apps with Greenify. Plus, after installing a custom kernel via Magisk, temps dropped and I felt a noticeable boost in performance. Honestly, scheduling battery saver mode during daytime also helped extend battery life.
My go-to settings for the Redmi series are enabling **Game Turbo** only during gaming sessions and disabling it otherwise. This minimizes heat buildup and battery drain caused by continuous CPU boost triggers. Also, under **Developer Options**, setting "Window animation scale" and "Transition animation scale" to 0.5x makes the UI feel smoother, and turning off **GPU rendering** reduces RAM pressure. Bro, these tweaks aren’t just for Redmi—they work similarly on **OnePlus** devices too. OxygenOS already keeps animations low for better performance, but since OnePlus lacks Game Turbo, it doesn’t offer that extra "speed boost."
When it comes to custom ROMs, **Pixel Experience**-based ones have worked great for me. LineageOS or Pixel UI, being close to AOSP, cuts out unnecessary bloatware and auto-cleans system cache more often. Compared to Redmi’s MIUI, which sometimes feels bloated due to background services, this setup reduces RAM usage by **15-20%**. For kernels, I’ve seen **Kirin 990**-based devices with custom kernels hitting stable boosts between **2.2GHz–3.1GHz**, which is more consistent than Redmi’s stock kernel. This helps with long-term heat control too.
In short, MIUI’s built-in power tools (like "App Sleep Mode") are a decent start, but if you want **aggressive optimization**, pairing **Pixel Experience with a custom kernel** gives you a more balanced experience—better performance and battery life than Samsung’s One UI on the same hardware. If you’re trying it out, clear the system cache a couple of times first, then flash the ROM and kernel. You’ll notice the difference within a week.
The fastest method I've tried is turning off "GPU render" and enabling "Hardware acceleration" in Developer Options, then using Greenify to put background apps to sleep and reduce RAM usage. Honestly, switching to the "performance" governor via Magisk gave me around a 10% FPS boost on my device, bro.
