My phone battery is taking a hit after more than 1.5 years of extensive use. Since it is still under warranty, can I claim it? There was a popup from Huawei app (support) telling me that my battery is degrading but I am not able to find it anymore after clearing it.

Just a finding between One UI and EMUI 12. After testing both phones (S8 and mate 20 Pro) for their screen mirroring capability, (wireless projection and smart view), it is clear that oneUI is far superior. Mate 20 Pro is laggy and did not fill the screen entirely. Smart view in Samsung filled the entire screen with very minimal stuttering and artefacts. Both also have desktop mode and Huawei version is totally laggy and unusable. Is it just me or everyone is facing the same experience?

My Huawei Mate 20 Pro finally kicked the bucket yesterday. Just scrolling through Facebook and suddenly hang and restart. I was just recently replaced the battery for RM99 at SC. Probably mainboard issue from googling, CPU detach from chip is the most likely culprit). Contemplating on buying another board from aliexpress for RM160~ or send it for CPU reball just to make it alive again. Great thing I was able to back the data up since it can be booted fine if I let it cool down.

I really hate to replace phone (need to reinstall apps, banking app all need to reauthorize and wait 24 hours, and Desktop Projection feature is the best!)

Phone is alive now with a replacement mainboard. I was just wondering anyone here successfully able to upgrade from EMUI12 to HarmonyOS 3 by changing region to China? I have tried but update is still not being pushed to me device.

Yes. Total damage was around RM180+. My mainboard kaput few days after I replaced the battery at Huawei SC. Not sure whether it is coincidence or during battery change (removing back panel), the phone was subjected to a too much heat on the heat plate, causing chip to detach

I am very surprised that Huawei also provide update for HarmonyOS 4 for mate 20 Pro which is already 6 years since its release.

The replacement board kaput after 6 months. :/
Total surgeries throughout its lifetime:
2 battery replacements
1 main board replacement

Total lifetime = 5 years ++ (Nov 19 - May 25)

It's been a great experience with Huawei which made me opt for Honor Magic 6 Pro (need the desktop projection feature)

ps: I guess I'm late to the party but 120hz is nice yo

Yes I got the phone to not reboot by playing Spotify in the background in order to recover the data. Both original and replacement mainboard kena 4 cpu offline.

Regarding the reball service, last time I did survey, in my area quite a few able to do it for RM400++

Any phone also is advisable to back up the data regularly. For hassle free, can use cloud solution but need subscription. If your FIL don't use any banking apps, I don't see the need for updates. Unless apps no longer working.
