One hundred twenty frames per second changes how a shooter feels. Motion turns buttery and tracking a moving target becomes easier. Aiming feels connected to your thumbs in a way sixty frames never quite achieves. Once you play at 120FPS going back feels like moving through water.
Many phones hide the 120FPS option behind device checks. A game may offer it only on approved models even when your hardware could handle it. Other phones offer it but throttle within minutes because heat builds fast. Unlocking the option is only half the job. Holding the frame rate is the other half.
This guide covers all three games separately because each gates high frames differently. You will learn the official path first and the safe config tweaks second. You will learn cooling and graphics tradeoffs that keep 120FPS stable. By the end you will know whether your phone can truly sustain it.
Check hardware before chasing 120FPS
Your screen must support a 120Hz refresh rate or higher. A sixty hertz screen cannot display 120FPS no matter what the game renders. Check display settings for a refresh rate option. If only sixty hertz appears then the hardware caps you and no tweak changes physics.
Your chip must sustain high frame rendering under load. Flagship chips from recent years handle it in most scenes. Midrange chips may hit 120FPS in lobbies and collapse in fights. That collapse feels worse than a steady ninety. Judge by busy scenes and not by menus.
Cooling capacity decides sustained performance. A phone with a vapour chamber holds high clocks longer. A thin phone without one throttles sooner. Play a demanding match for twenty minutes and watch the frame counter. Sustained frames matter more than peak frames.
Battery health also plays a role because a worn battery cannot deliver peak power steadily. A phone at eighty percent health may throttle sooner under load. Check battery health before blaming the game for drops. Hardware reality sets the ceiling for every tweak.
Unlock 120FPS in PUBG Mobile
Open PUBG settings and go to Graphics. Look for a frame rate option that includes Extreme Plus or 120FPS. The label varies by version and device. If it appears then select it and lower graphics quality to Smooth. Smooth graphics free the processor to hold high frames.
If the option is missing then your device is not on the approved list for that version. Updating the game sometimes adds new devices. Check the patch notes after each major update for expanded support. Approval lists grow over time as developers test more models.
Config file tweaks exist in community guides but they carry risk. Editing game files can trigger anti cheat detection on some versions. A flagged account can lose ranked progress or face a ban. Prefer official settings over file edits whenever the official path exists. No frame rate is worth an account.
Test PUBG 120FPS in a hot drop area with many players. Lobbies and empty fields flatter performance. A busy town with vehicles and gunfire reveals the truth. If frames hold above one hundred there then the setup works. If they collapse to sixty then lower settings further.
Unlock 120FPS in COD Mobile
Open COD Mobile settings and go to Graphics and frame rate. Select Max frame rate if your device shows it. Pair it with Medium graphics quality as a starting point. High graphics with Max frames overheats most phones within a match.
COD Mobile ties frame options to device profiles that update with the game. A phone that lacked Max frames last season may gain it this season. Keep the game updated and recheck after major patches. Developers expand profiles quietly without announcements.
Disable extra effects like depth of field and bloom when chasing stable frames. Those effects cost heavily during explosions and smoke. Their loss is barely visible during fast combat. Clarity and stability beat cinematic effects in a shooter.
Use a controller or a cooler for long ranked sessions at 120FPS. Touch play generates hand heat that adds to chip heat. A controller keeps hands off the back panel. A cooler removes heat directly. Both help sustain the frame rate you unlocked.
Unlock 120FPS in Genshin Impact
Open Genshin settings and go to Graphics. Set FPS to 120 if the option appears. Genshin gates the option by device and by graphics preset. Lower render resolution to Medium if frames struggle. Resolution costs more in Genshin than in shooters because the world is vast.
Genshin is the most demanding of the three games at high frames. Open world exploration with weather and particle effects taxes every part of the chip. Expect drops in busy cities even on flagship phones. A stable ninety in Genshin often feels better than a swinging 120FPS.
Turn off motion blur and crowd density extras when chasing frames. Those settings beautify cities but cost heavily. Shadows at Medium rather than High free significant performance. Genshin still looks gorgeous at tuned settings because art direction carries it.
Play Genshin at 120FPS near a charger on long sessions. High frame rendering drains battery fast. A session that lasts two hours at sixty frames may last barely one hour at 120FPS. Carry a power bank for travel play and reserve 120FPS for home sessions.
Keep 120FPS stable with cooling and settings
Remove the case and keep the room cool during high frame sessions. Heat is the enemy of sustained 120FPS above all else. A phone that starts at 120FPS and throttles to sixty feels inconsistent. Cooling discipline keeps the experience premium.
Cap background activity before launching any of the three games. Close streaming apps and pause cloud backups. Background work steals processor cycles that high frame rendering needs. A clean launch gives the game full access to the chip.
Lower one graphics setting at a time when frames drop in fights. Shadows first and then effects and then resolution. Each step frees a chunk of performance. Stop lowering when frames hold steady in the busiest scene. That point is your personal sweet spot.
Revisit the general performance playbook when problems persist. A guide to stop lagging in mobile games with 5 performance fixes covers heat and network and memory systematically. High frame play rewards the same discipline at a higher standard.
adb shell dumpsys display | grep -i refresh
adb shell dumpsys gfxinfo com.example.game | grep -i -A3 "frames"The code block above is an original example written for this article. It shows diagnostic commands that report display refresh rate and frame statistics from a computer with developer tools. Replace the example package name with the real package of your game. It is a learning aid for verifying that 120FPS actually renders.
Account safety deserves emphasis when chasing high frames through unofficial means. Community config edits circulate widely for all three games. Some edits only change graphics flags while others alter files the anti cheat watches. A single flagged file can cost ranked rewards earned over seasons. Official settings and patience for device approval protect an account worth far more than a frame counter.
Screen protectors and cases interact with high frame play in small but real ways. A thick case traps heat during 120FPS sessions and shortens the time before throttling. A matte protector reduces glare outdoors but can dull colours slightly. Test your full physical setup during a long session rather than judging frames in a cool room without a case. Real world conditions decide real world performance.
Cross progression between phone and other platforms affects how you value high frame play. Progress that syncs to a console or PC lets you switch devices freely. A phone session at 120FPS and a console session later share the same hero. Check sync settings before investing heavily in one platform. Shared progress makes every device in your setup more valuable.
Display overdrive settings on some phones push refresh rates higher at the cost of battery and heat. A 144Hz panel running a 120FPS game still renders at the game cap. Higher panel rates help only when the game itself renders above 120FPS. Match panel rate to game cap for efficiency. Extra hertz beyond the cap waste power without visible gain.
Common mistakes
The first mistake is unlocking 120FPS and keeping graphics at maximum. Maximum graphics plus maximum frames overheats almost every phone. Lower graphics to Smooth or Medium first. Frames matter more than shadows in competitive play.
The second mistake is editing config files to force an unsupported mode. Anti cheat systems may flag modified files. An account ban costs far more than a frame rate gain. Use official options and wait for device approval.
The third mistake is judging 120FPS in a lobby. Lobbies run easily and flatter every phone. Test in busy combat zones for five minutes. Real fights decide whether the unlock truly holds.
The fourth mistake is ignoring battery drain at 120FPS. High frame rendering consumes power fast. A dead phone mid match helps nobody. Carry a charger or a power bank for long high frame sessions.
Frequently asked questions
Why is 120FPS missing on my 120Hz phone?
Games gate high frame options by approved device lists. Your screen may support 120Hz while the game profile for your model does not. Updates expand the list over time. Recheck after major patches and keep graphics modest.
Does 120FPS improve my aim?
Higher frames reduce motion blur and input latency perception. Tracking moving targets feels easier for most players. The gain is real but modest compared with practice. Frames help skill show and they do not replace it.
Is 120FPS worth the battery cost?
For ranked matches the smoothness justifies the drain. For casual story play sixty frames saves battery with little loss. Choose per session rather than per phone. Competitive play earns high frames and casual play earns long battery.
Conclusion
Unlocking 120FPS across PUBG and COD Mobile and Genshin Impact starts with hardware truth. A 120Hz screen and a strong cool chip set the ceiling. Official settings and modest graphics and disciplined cooling hold the rate steady. Avoid risky config edits that threaten your account.
Your concrete next step is to open one of the three games today and check whether a 120FPS option already exists. If it does then pair it with Smooth or Medium graphics and test a busy scene for five minutes. If frames hold then you have your setup.
