Android OS takes a lot of cpu

[erna56]

I bought my Xperia XA 3 months ago, it worked perfectly but after last update it started showing my Android OS is using 1.6 gb of cpu and lag. Is there any way to reduce it?

can you try to download CPU -Z on the google play store and see your realtime RAM usage.

try to restart your device to free up ram

Thank you for reply
And yes, I did download CPU-Z, it shows my RAM is quite high. When I restart my phone it works normally for half an hour and lags again. I guess I'll need to wait for new update to fix this bug 😕
