MacBook Pro 2017 battery life?

Ive had Macs since 1988. MacBooks since they were available. I bought a new MacBook Pro a month ago. The battery was a 3 or 4 hour battery. That's it. Really bad. I complained, traded for an Air (screen is shameful). Then got another Mac, lost money in the exchange. Hours at the store, with AppleCare, Chatting, get no where. Then, One chat advisor suggested resetting the "SMC". It resets lower level power issues. I did this and now have a 7 - 8 hour battery.

You hold shift-control-option and push the power button. Hold for exactly 10 seconds and release. That's it. Try that and resetting the p-ram. That's option-command-P-R and start the Mac. Let run with all buttons pressed for about 20 second. It should restart twice.

But I think the SMC is the key... Or get a PC. LOL

After a long talk and diagnostics with Apple, not much was found. I did have McAfee installed and my whole system was migrated over from my old MBP via Time Machine. I uninstalled McAfee and the time has slowly started to creep back up each day over the last few days. When I unplugged it today it said 12 hours of battery time remaining. After 30 minutes of use it says 7:30 remaining so that could have been a factor or the factor for me. I will try to reinstall McAfee later and see what happens then.

The only other option is to backup your machine, wipe it clean and reinstall each app one by one and see what could be causing the battery drain. Time consuming and a major pain in the butt but it may be the only way to figure out what's causing the problem.

How long have you had it for? When I first got mine the battery life wasn’t great and I noticed that lowering my keyboard backlight and my brightness down that it would last longer. Also anytime I would use a different web browser besides safari it would kill it more too. But give it a couple weeks for it to set up. Let me know if this helps!

Hi , it seems we have similar observation, i just got my mbp 13 2017 without touchbar 1 week ago and the battery consumption has been efficient until I plugged in an apple usb hub with a witrless mouse. The battery went from 100 down to 66 percent in just around 3hrs.

Do not use safari. That makes some difference. Still apple should do something about it. This is frustrating situation.

Batteries - Maximizing Performance - Apple

The Energy pane shows overall energy use and the energy used by each app:

• Energy Impact: A relative measure of the current energy consumption of the app. Lower numbers are better. A triangle to the left of an app's name means that the app consists of multiple processes. Click the triangle to see details about each process.
• Avg Energy Impact: The average energy impact for the past 8 hours or since the Mac started up, whichever is shorter. Average energy impact is also shown for apps that were running during that time, but have since been quit. The names of those apps are dimmed.

Use Activity Monitor on your Mac
Reset the System Management Controller (SMC) on your Mac
Thank you for using Apple Support Communities. Have a nice day.

Oh, and I keep the keyboard lighting at 4 bars and the display not over 10 bars. This also helps. But Apple should have put in a larger battery. This is really unacceptable! I am still thinking about returning the again and getting a Yoga 920! ****** off beyond belief...

Hi did you fix your bettery issue? i have the same issue my new macbook pro lasts only 2 hours i don't know why i went to the apple store they said everything is perfect if still you need more checkup leave this computer for 10 days, which is not good for me and my work.

did you solve this issue ?please let me know. Thanks

If you still have battery issues after optimizing your computer's performance and checking for malfunctioning software processes, test in Safe Mode. Safe Mode limits the active items on the system and allows testing in a more minimal environment. If the battery life is better in Safe Mode, you might need to do further software isolation for the items disabled by Safe Mode to determine what the power draw is while not operating in Safe Mode.

Have a good one.

My MacBook Pro 13 in with touchbar is draining out within a couple of hours; the battery is no good and I have tried the usual fixes.

PS: The MacBook Pro 2017 was bought a month ago and the battery worked well for a couple of weeks. Now it is in super fast drainage mode and for someone who travels this is a nightmare issue!

I am facing the same issue with new Macbook pro 15inch with touch bar (2017 Model). Battery is lasting for 4 to 5 hours max.

I got new macbook pro touch bar 15" my bettry life stands only 2 hours i was thinking my older macbook pro retina had the same bettery life why i bought this..

did you fix it in anyway?
