Ios 11.3 on my iphone 6

[Sendmenudes02]

hello everyone. I’ve been having problems since I update to ios 11.3. I was on ios 11.2.6 but it was very laggy. So, a few days ago I update to 11.3 by a clean install (using the IPSW from the official page) and installing it from Itunes, But still being laggy, I don’t know why. My iphone 6 is new and the battery capacity is 100%. Should I do a restore from itunes to see if that fix my problem?
I’ve have installed it by OTA and then by clean install using IPSW but neither of two worked for me, its laggy as hell and shouldn’t be like that even though is an iphone 6. Last thing might work is doing a restore but i Dont know. Lets see ehat you think. Somebody help me please.

Laggy as hell = opening and closing apps delaying time. Iphone get hot even using instagram , facebook or youtube, even whatsapp....

Your hitting the limits of the hardware your phone is equipped with.. It will take a bit longer to accomplish tasks compared to newer phones

If you have time, you can try a DFU/restore via iTunes to alleviate some delay but i do believe possibly due to hardware limits of the CPU similar to 5S. It is slightly better than 5S. The significance performance boost for SE, 6S and up.

The 6 and below only have 1GB of system ram available, 6S and above have 2GB - that alone means a step-change in performance between the two, particularly when lots of apps are open.

Minimise the number of apps you keep open and you’ll make the best of the limited hardware, maybe turn Reduce Motion on too.

It's iOS 11, it even lags on my iPhone X here and there.
