Start by identifying whether the problem is network lag or slow, uneven rendering: connection fixes may help high ping or disconnections, but they will not necessarily fix low FPS, freezes, or heat-related slowdown. Then work through the game-specific, reversible steps below before considering disruptive actions such as logging out or reinstalling.
First identify what kind of lag you are seeing
High ping, lost connection, and rubber-banding point toward a network problem. Low or unstable frame rate, stuttering, freezes, or slowdown when the phone heats up point more toward rendering or device performance. These symptoms can overlap, and the official support steps do not provide diagnostic thresholds, so treat this distinction as a starting point rather than a definitive diagnosis.

- Connection symptoms: Check the connection and signal before changing graphics settings.
- Rendering symptoms: Try app and phone maintenance, then use only frame-rate options offered by the game on your device.
Check the connection
BGMI
Make sure the connection is stable. If the problem continues, try switching between Wi-Fi and mobile data (4G), or move somewhere with a stronger signal. These are troubleshooting steps, not a guarantee that one connection type will always have lower ping. If network fluctuation remains after trying them, BGMI advises contacting support.

Call of Duty: Mobile
Use a stable Wi-Fi connection and check whether the connection itself is troublesome. If Wi-Fi is the issue, Activision suggests restarting the router. Changing networks may help isolate a connection problem, but Wi-Fi is not automatically faster or more reliable in every location. Call of Duty: Mobile slow-gameplay troubleshooting

Try low-risk maintenance for slow or stuttering gameplay
Call of Duty: Mobile
Try these steps one at a time, checking whether gameplay changes after each one. Activision recommends them for slow gameplay; they are not a promise of higher FPS.
- Update Call of Duty: Mobile.
- Install available system software updates for the phone.
- Close background apps, messaging pop-ups, and overlays that may be running over the game.
- Restart the phone.
- Uninstall apps you do not need if you need to free RAM.
- Clear the game’s cache. The cited guidance recommends clearing cache, not clearing app data.

BGMI
Exit the game and free up phone storage. If the problem continues, use the Repair option on the right side of BGMI’s login page. Reinstalling is a later step, not the first one to try. Before logging out or reinstalling, guest players should secure account access: BGMI warns that logging out as a guest may erase character progress. BGMI’s troubleshooting and guest-account warning

Use only frame-rate settings your game supports
BGMI: check for the Ultra Extreme option
BGMI’s 120 FPS option is limited to select high-refresh-rate devices with the necessary hardware and software support. In the game, check Settings > Graphics for Ultra Extreme. If that option is absent, BGMI’s guide says the device does not support 120 FPS. A phone display set to 120 Hz alone does not make the option available. BGMI’s 120 FPS guide

Call of Duty: Mobile: choose from the options shown
The reviewed Call of Duty: Mobile support guidance does not establish a universal high-FPS device list or a best setting combination. Use the frame-rate choices displayed by your game and device. If performance remains unstable, lowering graphics is a device-dependent troubleshooting option to try—not a guaranteed or universal fix.
Do not confuse screen refresh rate with game FPS
Refresh-rate behavior can vary by game even on the same phone. For example, Xiaomi says the POCO X7 Pro’s Game Turbo high-frame-rate mode supports 120 Hz for Call of Duty: Mobile while BGMI runs at 60 Hz. That is a model-specific manufacturer statement, not a rule for other phones or proof that a 120 Hz display produces 120 FPS in a game. Xiaomi’s POCO X7 Pro Game Turbo FAQ
