notifyitemchanged() frame skipping every second

Question

app lags when scroll the recyclerview tried on physical device one plus 9 pro same thing happen minor lags when scroll. If i remove countdown it work smooth. below is my recyclerview adapter.I also used custom countdown timer in runnable class same thing lag. in first try i have created countdowntimer in onbindviewholder but according to this answer onbindview create countdown timer every time when scoll so i moved in viewholder.

public class AdapterFixturesList extends RecyclerView.Adapter<AdapterFixturesList.MyViewHolder> {
    private List<BeanHomeFixtures> mListenerList;
    Context mContext;
    CountDownTimer timer;

    public AdapterFixturesList(final List<BeanHomeFixtures> mListenerList, Context context) {
        mContext = context;
        this.mListenerList = mListenerList;

        long maxTime = 0;
        for (BeanHomeFixtures item : mListenerList) {
            if (!item.getTime().equalsIgnoreCase("")) {
                maxTime = Long.parseLong(item.getTime());
            }
        }

        timer = new CountDownTimer(maxtime, 1000) {
                @Override
                public void onTick(long millisUntilFinished) {
                    for (int i = 0, dataLength = mListenerList.size(); i < dataLength; i++) {
                        BeanHomeFixtures item = mListenerList.get(i);
                        if (!item.getTime().equalsIgnoreCase("")) {
                            item.setTime(String.valueOf(Long.parseLong(item.getTime()) - 1));
                        }
                        notifyItemChanged(i , "time");
                    }
                }
                @Override
                public void onFinish() {
                }
            }.start();

        }
public class MyViewHolder extends RecyclerView.ViewHolder {
        TextView tv_TimeRemained;
        ImageView im_Team1, im_Team2;
public MyViewHolder(View view) {
            super(view);
          
            tv_TimeRemained = view.findViewById(R.id.tv_TimeRemained);
        }

    }
@Override
    public int getItemCount() {
        return mListenerList.size();
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        final View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.adapter_fixtures_list, parent, false);

        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int position) {
final String time = mListenerList.get(position).getTime();
if(Long.parseLong(time) > 0){
                long FlashCount = Long.parseLong(time);
                long millisUntilFinished = FlashCount * 1000;
                long Days = TimeUnit.HOURS.toDays(TimeUnit.MILLISECONDS.toHours(millisUntilFinished));
                long Hours = TimeUnit.MILLISECONDS.toHours(millisUntilFinished) - TimeUnit.DAYS.toHours(TimeUnit.MILLISECONDS.toDays(millisUntilFinished));
                long Minutes = TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millisUntilFinished));
                long Seconds = TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished));

                String format = "%1$02d";

                    holder.tv_TimeRemained.setText(String.format(format, Days) + ":" + String.format(format, Hours) + ":" + String.format(format, Minutes) + ":" + String.format(format, Seconds));
            }
            else{
                holder.tv_TimeRemained.setText("Entry Over!");
            }
    }
}
