New battery, disappointing runtime.

Apple Premium Reseller & Authorised Service Provider.

I've had a quick look at %CPU and kernel_task is top with 17.9%, but Time Machine is having the biggest impact under the Energy page - could it be that?

Not liking replying to my own reply, however back up has completed and I charged to 100% (green light on charger lead) and battery time remaining is showing at 3hrs/90% and it's been unplugged around 20mins. Any suggestions?

Here are the results (and thanks for helping).

I'll try resetting the SMC. The manufacturer is SMP.

Thanks for helping.

Are you saying that CleanMyMac has be proven to reduce battery life and if yes by how much? Or do you just not like it?

Thanks again for the help.

Susan

OK, removed it yesterday and zero impact on battery life so I guess it's not that 😮.

However, I've just stopped Time Machine trying to do backups on battery power and that does seem to have made a positive impact in increasing battery life by over 2hrs within 10 mins of making the changes, and it's still going up 😎. 69% and over 4hrs so far, so I think that might be it.

Thanks for the help again.

Susan

PS If this has solved it I'm going to try reinstalling CleanMyMac - rebel that I am, and will let you know if it does reduce the runtime
