Hello, I recently purchased an LG Gram and have been experiencing battery problems that seem connected to driver settings. The product listing claims 14 to 20 hours of usage, but I’m seeing much shorter ranges. With a 90Wh battery and a low-power CPU, the numbers don’t match expectations. I usually get around 10 hours of web browsing before the battery drops significantly, but anything else cuts it nearly in half. For instance, at about 60% charge I’m left with roughly 6 hours, and this drops to around 2.5 hours when playing videos on YouTube. Last morning I attended a Teams call for 1.5 hours and my battery fell from full to 70%, suggesting only about 5 hours of usage. Chrome was running in the background with Bluetooth headphones on, yet the battery still dropped fast. I suspect the video decoding process is draining power too much. After turning off Bluetooth, the remaining time improved slightly. This leads me to believe the Bluetooth, WiFi, and possibly iGPU drivers need updating. My concerns are: the Intel website mentions that updating the graphics driver might affect LG’s optimizations. Should I proceed with the update, or should I be cautious? Additionally, I noticed "searchhost.exe" using more bandwidth than Chrome over the past week. That’s unusual since Chrome is always active, so I’m unsure what this process does and whether it could be the real issue instead of the drivers. Any advice would be appreciated.

Utilize enhanced power settings to cap processor usage below 100%, switch wireless transmission from peak performance to power-saving mode. Check if background scripts or Chrome are consuming excessive CPU resources—consider using add-ons like NoScript or Privacy Badger to block unwanted content. Try Firefox, which has been available since 1994 as Phion or Firebird. Disable Wi-Fi constantly unless accessing web pages or downloading files. Once a page finishes loading, turn off Wi-Fi. If you have access, adjust your router to emit 10 beacons per second unless the network is congested. This default setting may force devices to react to every beacon, potentially draining batteries faster; test changing the limit from 100% to around 1000 time units or nearly one second. You may also boost DTIM to 2, but be cautious as it impacts UDP packets—consider a test voice or video call first.
