Slower Charging While On Calls

Hello,

Has anyone noticed that charging speeds drop massively while on a call? Using official charger and charging has 45 mins left it estimated. Had a call for 20 mins and once off battery percentage only increased a few percent and still said 40 mins to full charge. Once off a call the charging went back to regular speed.

Any ideas anyone? Cheers

There's likely 3 reasons that cause this:
1) Making calls uses more power
2) Phones heat up while on calls, and so the phone slows down the charge in order to protect the battery at higher temps
3) The phone charges at different speeds when idle, and screen on vs screen off (slower when screen is on and phone is not idle, such as on a call)

I think all of those together is what's contributing to your issue.

thanks, that makes sense I guess. Just not used to it coming from Huawei phones unfortunately.
