i treat gadgets as consumables nowadays. I dont need it to be in pristine condition after 2 years. Anyhow i will change it in 18 months. Why let the next owner enjoy a brand new look device? lol, that's just me anyway

That will not happen for sure with TW.

Based on the initial reviews, looks like it will have a good battery life since Samsung limits CPU and GPU clocks. The new raw exynos is simply overpowered hence their decision would be reasonable plus to match with Snapdragon variant of it. Anyway we don't know if that's the final setup until retail units are out.

Oreo itself is already more power efficient. No where is oreo for my note 8?

I had Oreo on my ex Mi A1 and I found it to be less power efficient compared to Nougat before I updated though. Don’t know if it was some setting or some rogue app. Anyways, I believe they just updated the S8 and S8+ with Oreo (before pulling it and reinstating it again) so maybe your Note 8 update is 3 months away or so

Ya, I suspected so. Naturally using a device with Vanilla Android I didn’t think twice to update it, and after I did, mi also pulled the update due to bugs Anyways, I didn’t encounter any significant issues, just felt that the power efficiency was not as good as before. So, yeah, you may have a point. Might be best to stick to Nougat at this point of time.

Battery life is similar to S8 series according to one of the Youtuber named Xeetechcare.
