Green is first run.
White 2nd run.
- Couldn't get the car slowed down in time for turn 1. missed the apex and that cost him. That makes you go wide and then you have to slow the car down more, later on the throttle.
-Same thing in turn 5 and turn 7.

He seems to adjust his braking after that, he's coming off the throttle earlier, but he's lost too much time by then.
If had to guess at his thinking ..... He didn't get as much braking with the new set of soft tires as he was expecting.
That set him off on the wrong foot. Then he tried to brake later to make up for it and that's always going to be really touchy. It didn't work for him.
If he did use used tires on the first stint, that might explain why he was surprised by the lack of improved braking. Either way, I think his first run was a banker, then the 2nd run was high risk endeavour to move up the charts cause the car wasn't fast enough.
Yes, he didn’t took t1 in the best possible way, he did run a little bit wide compared to first lap,
and as I said, he is using different braking points and at some corners slightly different lines.
I am not sure if we can blame the breaking performance everywhere, or Alonso just changing his breaking points and his lines a bit, on purpose. He did say after the lap, that it was a good lap after all.
The real problem though starts with the breaking at turn 5 how he enters and how he exits that corner. After exiting t5 he is mostly losing time and that goes on through 7,8 and also exiting turn 9 and up to turn 12.
The break even point though, where his second run became even with the previous lap was at turn 12.
Up until then he was managing to be slightly faster, even with the breaking points he had and the lines he took.
In your telemetry graph, the point in time that you marked is when exiting turn 12. As you can see due to better traction probably, or slightly different line, he exits the corner with higher speed than the previous lap (135km/h to 131km/h). Logic say, that with better tires, better grip, better traction and higher speed at the exit of t12, you will reach a better top speed just before t14.

But he doesn’t !!! As you see in the telemetry graph above in which i have marked the end of the straight just before t14, he keeps loosing time in the straight and he ends up with a lower overall top speed (341km/h to 343km/h). It is there, where i think following a car around 4 seconds behind may be helpful in this circuit. Not only there actually, but in other straights as well.
Notice, in the bottom part of graph, the white graph line is slower in kph but is moving further up and away from the bottom green graph line? The green is going faster in speed at the end of the straight. The white line moving further above the green line means, on that run the white line was accelerating faster than the green. Alonso nailed the braking and the fresher tires allowed Alonso to get on the throttle earlier and apply more power down. Since they are the same car, once they both get on full throttle, they'll both accelerate at the same rate but since the white line was on the throttle earlier it keeps a speed advantage for most of the straight. The top speed difference is likely because on the white line he applied the powerer sooner and harder that he ran out of battery. The Xtra 2 kph had little effect on his lap time cause it lasts such a short time, literally a fraction of a second. Under breaking he loses time as he brakes harder and scrubs off speed faster on the white graph line than on the green line. Guess on the green run when he smoked the right tire he still hit the apex.
It's the opposite.
The white line moving further above the green line means Alonso is losing time (overall) in the straight compared to his green line lap. The white line didn't keep a speed advantage. It lost the speed advantage and lost time overall.
Yes Alonso with better tires, grip and traction had better exit and better speed at the begging of the straight, but he kept losing speed and ended up with a lower top speed having lost in the process almost a tenth (around 0.090) in that straight.
With better tires and better acceleration doesn't make sense for this to happen.
As i said IMO that happened either because he didn't had a car in front running 4 seconds ahead or they had adjusted something regarding balance/df in the pits, or (as you said) something else regarding battery, deployment etc.
But watching how other cars run out there, i believe running 4 seconds behind another car, overall is beneficial in this circuit.
