Device: Kindle PW5, Kobo Libra 2, Kindle PW1
It is. I have both devices (and have been comparing everything about them for past 2 months, still trying to convince myself to resell the Kindle (because previous 2 PW5 ended up in a bootloop) and keep the Kobo) so no point in trying to convince me. Especially when a know Kobo fanboy is trying to do that.
The only good thing about Libra 2 is its screen.

Facts are facts, no matter what is "the truth" in @JSWolf's fantasy world.

1) Fact #1: Over 12 month period I've charged my PW5 6 times, and for that period of time I've read ~7200 screens. Add ~35% to that number to get total page count of typical paperback book.
You can do the math to get how many pages / screen that is for a single charge.

2) Fact #2: Kobo Libra 2 battery is empty by the time I've read about 500 screens 10 days is the average time I get between 2 charges.

3) Fact #3: I even tested and made notes on how Kindle PW5 discharges the battery while not used. Each night at 23:00 I would wake it up, use it for couple of minutes (to give it chance to flip the percentage value is it was close to doing that) and the made a note of battery level percentage:

Code:
- 13.01.2024. at 01:20 - device booted - 51% 
- 13.01.2024. at 23:09 - 50%
- 14.01.2024. at 23:00 - 50%
- 15.01.2024. at 15:00 - 49%
- 15.01.2024. at 23:00 - 49%
- 16.01.2024. at 23:00 - 49%
- 17.01.2024. at 23:00 - 49%
- 18.01.2024. at 23:00 - 49%
- 19.01.2024. at 23:00 - 49% > device restarted > still 49% > used for a minute > 48%
- 20.01.2024. at 23:00 - 48%
- 21.01.2024. at 23:00 - 48%
- 22.01.2024. at 23:00 - 47%
- 23.01.2024. at 23:00 - 47%
- 24.01.2024. at 23:00 - 47%
- 25.01.2024. at 23:00 - 46%
Basically Libra 2's battery lasts less than even my 11 year old Kindle PW1 (that has similar battery capacity and has in last couple of years finally started to last noticeably less than it did originally) and instead of expected 25-30% less (= 70% of) battery life of PW5 (expected since PW5 has 1700 mAh battery capacity and Libra 2 has 1420 mAh) Libra 2 in reality has more like 30% of PW5's battery life. Which is appalling and pathetic for a eInk device.
