I never played PvZ2 on Lollipop. However, it runs smoothly on my device (4.4.4 KitKat), so you may need to factory reset your phone.

Warning: Factory resetting your phone will delete all your data.

Another possibility of why it's laggy is because your GPU is Mali-400. It's not really good for gaming since its specs is lower than my Adreno 305, so you may need to get a better phone. My recommendation is to get a Xiaomi phone since it's cheap and high-end. BTW, here's my phone info:

Xperia L

OS: Android 4.4.4 KitKat CyanogenMod 11
