But i used to charge my phone till 100%, since i bought my phone from 2020.
I am using that 85% restriction, after i saw that 94% to 100% charge jumping.
So, not sure about that.
If in future i feel battery degradation impacting my regular life, i will try to change the battery first as this device can be used for at least next 2 years easily.

Hopefully, there will be some solution!

I think as both of our phones are already 3 year old, thus battery is losing it's earlier backup capacity, hence the problem you mentioned happening with our phones.
I am also using my phone now with that 85% charge restriction on as watching that 92% to 100% jump charging impacts mind more than regular usage.
My daily usage is not impacted because of this battery problem for now but if i face more problem in future, then i may consider replacing the old battery with new one and continue to use it.
You can do the same as our devices can be used for at least next 2 years easily if 5G is not a major need.

I am facing the problem of battery now on my M31. Phone charges normally upto 93% but after that it reaches to full battery within 2-3 minutes. I have tried both fast and normal charging, done battery Calibration but didn't work!
Now battery drops very quickly if i charge my phone beyond 92% but charging approximately upto 85% gives better endurance!
Can anyone help....?

ApriliaGman, 02 Oct 2023I hope this might help some of you with the reboot problem ... morePlease leave a comment if any of you try my fix method and let me know your outcome. It is possible that it is a BGA problem that needs reballing with a hot air rework station. But I am reluctant to try this as it is so easy to damage the board and components trying to reball. And am hoping it remains stable just using the thermal pad fix. So far things are still going well for my beloved M31

I hope this might help some of you with the reboot problem on the motherboard. I had the same reboot problem after upgrading to android version 12. It was so bad the phone was unusable. I think the issue lies with the thermal heat transfer pad that sits between the CPU and the aluminium heatsink. My thoughts are that it is a thin spongy material that loses it's pressure against the CPU and heatsink over time and that the extra work done running android 12 causes the CPU to over heat and shutdown continually because of the loss of pressure of this heat transfer sponge type material used. The fix for me was to replace this thermal pad with a 1mm thick silicone version that you can buy in different thicknesses from AliExpress. It's used in high heat dissipation for computer CPU's. I cut a square the same size as the CPU after removing all traces of the old foam type material and cutting the new material to the same size as the CPU. From memory it was about 12x13mm. The phone is now stable and I'm using it again as my main phone. For now the phone is working perfectly with no issues. The phone is very easy to take apart as the back case just clips on and can be removed by going around the case gently with a spudger tool being careful not to damage buttons etc. If you have this issue then you have nothing to lose trying to use this fix that worked for me. I hope this helps some of you as it's such a shame that such an awesome value for money phone is now letting so many people down. And in my opinion Samsung should be fixing this issue as it's a manufacturing fault due to this stupid thermal transfer sponge. At least that seems to be the issue from what I've found. I'm an electronics technician btw
