Turning off a few hidden Chrome settings made my phone browser faster

Chrome on Android can feel slow even though it is meant to be fast. Jon Gilbert of Android Police says he fixed the lag by changing a few buried settings. Turning off one of them, called Preload pages, gave his Google Pixel 10 Pro almost an hour of extra battery.

What changed

Gilbert describes slow page loads, stuttering animations and a browser that was slow to respond. He also says Chrome can drain hours of battery life. His fix was a handful of changes, some in the regular settings and some in a hidden menu reached by typing chrome://flags into Chrome's address bar.

The four tweaks

• Turn off Preload pages, which loads your most-visited sites before you open them.
• Clear Chrome's cache using the Settings app on your Android phone.
• Turn on GPU rasterization in chrome://flags.
• Turn on Experimental QUIC protocol in chrome://flags.

Preload pages tries to guess which sites you will visit and loads them early. Gilbert found it slowed Chrome for the first few minutes after opening. He says it makes sense only for long browsing sessions, and his are usually a few minutes.

The cache is temporary data Chrome keeps to speed up loading. It also keeps data from sites visited only once. Gilbert says clearing it removed 622MB that had built up over three months. It does not delete logins, though some sites may load a bit slower the first time afterward.

The hidden settings

Rasterization is how Chrome turns website data into the pixels on your screen. Usually the phone's main processor does that work. GPU rasterization hands the job to the graphics chip. Gilbert says it fixed slow loads on his MacBook Neo, then helped on his Windows PC, Chromebook, Pixel phone and Samsung tablet.

QUIC is an experimental way of moving web data, built as an alternative to older methods. Gilbert says it speeds up browsing by skipping the need for a response from servers. The downside is that network problems are harder to troubleshoot. He says that matters only to people who handle network admin tasks.

What to do

These are one writer's results, and he says no Chrome setting helps everyone. Change one thing at a time, so you can tell which change helped and which caused trouble. Watch how your phone behaves afterward.

If you browse for long stretches, you may want to leave Preload pages on. If you open Chrome briefly many times a day, turning it off may help speed and battery. Clearing the cache is the lowest-risk place to start.
