    I have problems with battery and heating I used my phone for 3.5 hours since full charge with intervals and my charge is at 27 and with 20 min of gaming my phone is at 42°C.

    Gallery is slow

    Even after unlocking there's always a banner telling me unlock for all features and data

    My last phone was OnePlus 7 pro and it was the best phone ever I had it for 2 years I had no battery or heating issues the phone was good as new when I bought my 9 pro,it never slowed down and the software was perfect..

    Based on oneplus official support centre solution abt 3 weeks back to the above problem is to go into recovery and clear cache and issue would be resolved. Nothing happened. About 3 weeks back some 3 guys sent DM to me to help resolve it. Shared log files and continuous followup yielded no results. Then a 4rth guy asked for log files and same process. Then came the display. While watching netflix the display went wild white grainy screen. I thought the phone was gone. Used feedback to highlight it. Now again no response.
    Now comes the response of yesterday during my discussion(chat) with oneplus support.
    Asked them again for solution they said clear cache since the functionality OS parts are not updated or works on the previous workflow it is always better to clear cache so the new functionality can operate smoothly. This is why it is always better to clear cache when OS gets updated and some apps which are crashing we clear cache to get it working again. then discussed regarding data transfer no issues with it either. They categorically mentioned that restoring backup of call logs, messages and contacts are not an issue at all and are a basic functionality for all phones. So I asked them this phone has the best configurations from the hardware perspective so why is this happening. We will get back. So waiting for their response.

    How does the banner look? Something seems very off on your device. Never any issues with unlock on mine.
    Were you on 10 or 11 on 7 Pro? Did you transfer all apps and settings via Switch or start from scratch?
    I always start clean with no transfers apart some files I copy back from online storage.
    When it comes to battery you might want to take a look at my guide.

    Normally caches are rebuilt when necessary. Doing a wipe mostly forces the system to recreate them and using more resources until building them up and thus it could generate more heat until done. While it's not impossible that it fixes a problem sometimes it can also create one (rebuild and higher level of heat during that time). One of the links in my guide describes caches and the optimizing process.
    I never wipe caches. I follow the ideas described in my guide and verify the the device has finished a background optimize via the bg-dexopt-job command I mention. An optimized device takes like 2 minutes to finish. A not optimized device can take more than 30 minutes depending on amount of apps.
    If doing a major version upgrade like switching OS version from 10 to 11 I do a factory reset and don't use either "previous device" data during setup nor a backup from Switch. I simply reinstall apps manually.
    The same thing when moving to a new device. I only copy a few files manually via Onedrive. I let all contacts sync via the Google account.
    I prefer the manual ways and not want to risk any conflicts or additional issues. Some cases of Switch transfers have created issues for some. For example one user that had an Huawei. Some Huawei specific apps also got transferred. He suffered from random reboots. Eventually it was found that the Huawei apps was the cause. Removing those got rid of the issue.
    A minimal transfer like messages and stuff like you mentioned should not cause an issue though.
    And regarding the Netflix issue. I've been trying hard to replicate this issue but failed. I've also been trying to help a other user that simply got his device wiped by support but never got an solution to this specific issue. He has been able to capture the bug while happing and sent it to the bughunters. It's not possible to do the screenshot step of the log collection though (or at least not for him. When it happens it's already too late)... I forwarded his errand via a staff member. Have you received some type of service number at the first contact with support?

    Hmm..
    Could it be some of those being in the background is in the status bar? That could possibly be an explanation of why you need to unlock twice. A locked app is already running in that case.

    Problem is why it happens for some but not everyone. I took a walk and recorded 4k 120 fps the full 5 minutes. 18-19°C in the shades. Had a Sandstone case on. Battery raised from 23°C to 26°C. Pretty decent I'd say.

    Don't know if using high efficiency codec can make a difference. I always use that.
    And then we have all the other possible reasons some phones could be hotter even before actually doing anything with it.
    Some seems to have a rather elevated idle activity for example.

    Outside temperature also plays crucial role in heating.
    If you're shooting 8k 30fps or 4k120fps in a sunny day the device will get hot within 2-3 minutes. It won't get hot while in a drizzling weather.
