[Vivo X80 Pro] wimbawaya:
Exact same experience here. During the heat wave the phone was easily idling at 46º C, meaning that even the slightest CPU activity caused it to overheat and start lagging. This never happened on my P30Pro...

2) Same here with the animations, I also thought it was probably a hurried LTPO implementation. But even switching to 60Hz, I still get a small lag.

3) Yeah, a lot of SD8Gen1 phones seem to share this issue. Such a shame 'cause this phone could be "the one to rule them all". I sooo wish they'd shipped to Europe with the Dimensity chip. Having the SD, aside from more over-heating and worse battery life, means we'll get fewer updates, and much later, since the amount of SD units sold will be way less than Dim9000, which is where Vivo is going to focus.

4) Yeah, IMPRESSIVE camera. My only gripes to far is that the best stabilization is on the 2X telephoto, which is kind of pointless for video, and that you can't use all 4 lenses in 8K, 4K, with AI on or with HDR10+ on. Night video is AMAZING though, although in my experience, AI does cause a bit of stuttering when panning (while completely smooth with no AI)

My only other gripes:

a) Notifications: I thought I'd gotten them fixed for Protonmail by unrestricting background power usage (Not that you have to do it twice: if you change it via app info > battery and select Unrestricted, and then go to Settings > battery > background power consumption management and look for that app, it's power profile will still appear as Smart switch, so you have to change it there too). But now they've started failing again. I often don't get notifications for Telegram or Whatsapp either, even though both have unrestricted power usage and were giving me no problems until now. 🤷‍♀️

Maybe Vivo will fix this at some point, but I use this phone for work (I'm a freelancer) and have lost a couple of projects already because I didn't see an email until an hour later and the project was urgent and assigned to someone else, so I can't really afford to have this kind of bug.

b) Bluetooth for calls often fails. I choose my BT earbuds (paired and used for music before making the called), and while in the call, the audio/mic being used are the phone's internal ones instead of the BT device, even though it shows the BT device as the active device for the call. This has happened with two separate BT devices and the only solution I've phone is to reboot the phone (which doesn't always solve it), or to unpair and repair the BT device.

c) I use the travel tracking app Polarsteps since I'm a digital nomad, and it took forever to get it working properly. It uses a mixture of wifi, cellular triangulating and GPS to determine your location in the background, and refused to update my location. After setting "unrestricted background power usage" via the two different ways mentioned before, to no avail, I had to delete cache and data, uninstall, and reinstall several times. What worked in the end was changing all these settings and granting all the right permissions

before

launching the app for the first time. Who knows...

d) Idle battery drain is pretty bad. Right now I've had my phone on for 10.5h since last full charge, with 3.5h SoT and 45% battery left (battery life seems to be improving gradually), but battery drain is 67% higher with the screen off the with the screen on. According to GSAM Bat. monitor, most of the background drain comes from Android system and Kernel.

Overnight, with WiFi and mobile data off (and, obviously, screen off), the phone drained 10% over a 7-hour period. With battery saver on and the same conditions, battery drain was 3%. Tonight I'll try with Flight Mode enabled.

On the plus side:

- I just discovered the "effect master" mode in the camera. It's awesome to be able to control exposure and saturation so easily, jus dragging you finger left/right and up/down. Try it out if you haven't!

- Motion autofocus works really well (as long as there's good lighting). How to use here. The video is actually worth watching in its entirety, good tips on certain features I wasn't aware of (Like "effect master" or "Super.raw".

- Again, the camera on this thing is AMAZING.
