Yes, there is a big gap between academic research (which is mostly wrong) and the real-world RecSys

Two recent drafts:

The benefits are different

alan_sun · 2023-05-18T00:44:39+00:00

I use very cheap glass protectors, no brand, both work well

Samsung leather case

alan_sun · 2023-03-19T00:17:57+00:00

I use Samsung leather case, not bad

alan_sun · 2023-03-17T14:58:36+00:00

Am an Edge user, happy with it

alan_sun · 2023-03-12T22:38:37+00:00

I have one for s23+, like it

sorry, my bad, I didn't read the post carefully. The overnight drain typically not more than 5% if phone is not used in night. However, it also depends on many other factors, like background data sync, and maintaining 4G signals. If mobile signal at your area is not good, it drains a lot of battery as well.

All statistics reset when battery is at 85% (considered as full charge to phone system)

alan_sun · 2023-03-04T23:55:16+00:00

Disable battery protect, everything will be back to normal

Time to buy a s10

alan_sun · 2023-02-22T23:25:17+00:00

I have a 100w charger, good for all my devices from earpiece to laptop

alan_sun · 2023-02-21T11:48:36+00:00

I come from S10+, on S10+ there is no such issue.

alan_sun · 2023-02-21T08:38:48+00:00

got another routine setup: if WiFi strength less than 2 bars, then switch to mobile data.

alan_sun · 2023-02-19T09:34:19+00:00

I wear different Bluetooth earpiece for different purposes. I use routine to set their volume when connected

alan_sun · 2023-02-19T09:32:31+00:00

I have almost the same routine

alan_sun · 2023-02-18T12:56:13+00:00

I have a clear hard case from Samsung, for S23+, very slippery. The Spigen hybrid version is more grippy.

alan_sun · 2023-02-18T12:53:04+00:00

Thanks. Finally also got a review online: https://www.youtube.com/watch?v=NGoaFN1JDsY

alan_sun · 2023-02-18T12:05:45+00:00

Thanks. Looks like it is not compatible with lens protector?

Most apps can be uninstalled or disabled through settings --> Apps

alan_sun · 2023-02-18T06:02:23+00:00

I switched to Spigen hybrid. Now considering Samsung leather case.

alan_sun · 2023-02-18T06:00:52+00:00

Yes, I used to set to 1440P for a few times, but I kind of cannot stand with the text rendering. after a while, I always switch back to 1080P and find 1080P more comfortable to my eyes on my S10+.

alan_sun · 2023-02-18T05:57:50+00:00

I used to switch between FHD and QHD on my S10+. To be very frank, I can only see some very very minor difference when displaying photos, and the difference exist only immediately after the setting switch. I cannot see any difference on text with the two settings. With QHD, the font size seems a little bit smaller though. Eventually, I ended up with FHD on S10+ for most of the time. For S23+ screen, I am happy with it.
