Roomba i7+ battery run short

Hi,
I have a 1300sqft house which I used to clean with Roomba 980 in the last 3 years. The 980 was great and cleaned all the house with 1 run without any battery charge in the middle.
I replaced it to a i7+ this week and it can't complete my house in 1 run like the 980 did. After 1h and 15min it goes into charging station till it full and then he will continue.

What is wrong? Does the i7+ work slower? The battery is defected?

Please assist.

The 980 uses a 2130 mAH Lithium pack and the i7 uses an 1800 mAH Lithium pack. The i7 pack is a much lower capacity pack which will lead to shorter run times.
