How to make subplots bigger and title in one line?

Hi all, I would like to make my subplots larger so that all four fill my window (quarter the window, so to speak)
Furthermore I would like to have the subplot title in one line and not a line break at each title where I write my initial values.
Any help is appreciated!
%plotting
fig1 = figure();
fig1.WindowState = 'maximized';
subplot(4,2,1)
plot(elapsedTime, volt/1000, 'b')
hold on
for i = 1:length(time)
if boole(i) == 1
line ("xdata",[elapsedTime(i),elapsedTime(i)], "ydata",[max(volt/1000)/1.5,max(volt/1000)], "linewidth", 0.5, 'linestyle', '--')
text(elapsedTime(i), max(volt/1000), [num2str(volt(i)/1000) "V"], 'HorizontalAlignment', 'left', 'VerticalAlignment', 'top', 'FontSize', 14);
end
end
title(["Battery Voltage over Time (Initial RSoC = " num2str(rsoc(1)) "%)"])
xlabel("Time in s")
ylabel("Battery Voltage in V")
xlim([0 elapsedTime(end)])
ax(1)=gca;
grid on
zoom on
subplot(4,2,2)
plot(elapsedTime, curr/1000, 'r')
hold on
for i = 1:length(time)
if boole(i) == 1
line ("xdata",[elapsedTime(i),elapsedTime(i)], "ydata",[min(curr/1000),max(curr/1000)], "linewidth", 0.5, 'linestyle', '--')
end
end
title(["Battery Current over Time (Integrated Capacity Q = " num2str(round(100*Q)/100) "Ah)"])
xlabel("Time in s")
ylabel("Battery Current in A")
xlim([0 elapsedTime(end)])
ax(2)=gca;
grid on
zoom xon
subplot(4,2,3)
plot(elapsedTime, temp, 'k')
title(["Battery Temperature over Time (Initial Battery Temperature = " num2str(temp(1)) "°C)"])
xlabel("Time in s")
ylabel("Battery Temperature in °C")
xlim([0 elapsedTime(end)])
ax(3) = gca;
grid on
zoom xon
subplot(4,2,4)
plot(elapsedTime, rsoc)
hold on
for i = 1:length(time)
if boole(i) == 1
line ("xdata",[elapsedTime(i),elapsedTime(i)], "ydata",[0,max(rsoc)+10], "linewidth", 0.5, 'linestyle', '--')
text(elapsedTime(i), max(rsoc-10), [num2str(rsoc(i)) "%" ], 'HorizontalAlignment', 'left', 'VerticalAlignment', 'top', 'FontSize', 14);
end
end
title([" Relative State of Charge over Time (Initial RSoC = " num2str(rsoc(1)) "%)"])
xlabel("Time in s")
ylabel("State of Charge in %")
ylim([0 100]);
xlim([0 elapsedTime(end)])
ax(4)=gca;
grid on
zoom xon
linkaxes(ax, 'x')

Ran in:
Using tiledlayout here seems to be a better option, as it gives you a better control over the spacing and padding.
Also, while concatenating with a string array, use +. When you simply place a numerical value in between strings, the value will be convert to a string scalar and the result will be a string array, which when provided as input to title() displays each element in a separate line -
x1 = ["String" 55 "Yo"]
x1 = 1x3 string array
"String" "55" "Yo"
x2 = "String " + 55 + " Yo"
x2 = "String 55 Yo"
tiledlayout(2, 2, 'TileSpacing', 'compact')
[X,Y,Z] = peaks(20);
% Tile 1
nexttile
surf(X,Y,Z)
title("Battery Voltage " + 55 + " %")
% Tile 2
nexttile
contour(X,Y,Z)
title("Battery Current " + 65 + "Ah")
% Tile 3
nexttile
imagesc(Z)
title("Battery Temperature " + 42.0 + "°C")
% Tile 4
nexttile
plot3(X,Y,Z)
title("Relative State of Charge " + randi(100) + "%")
