Apple's 14-inch and 16-inch MacBook Pros offer phenomenal battery life, especially against the competition. Battery life (hours:mins) MacBook Pro 14-inch M1 Pro: 14:08: MacBook Pro 16-inch M1 Max: Jul 11, 2021. #1. Hi everyone. I am trying to troubleshoot my MacBook Pro (Retina, 13-inch, Early 2015). I’ve had this laptop since 2016 and it just won’t turn on. I’ve tried all of the keyboard reset prompts (NVRAM and SMC). I’ve unscrewed the back panel, unplugged and replugged the battery connector, pulled out and reinserted the SSD
OK, I've pulled the battery and connected the charger. Computer has been sitting there for 5 minutes, no sign of life. I then pressed the battery indicator button on the left side and got the same 5 blinking lights. I then pulled out the RAM and tried again, plugged in and waited. Then pressed the power button. No sign of life at any point.
Macbook Pro Retina early-2015. 2.7 GHz Intel Core i5. Currently on Mojave ver. 10.14.6. This has happened a total of 4-5 times within the past month. Prior to these occurrences, I did change the old battery with a direct replacement Simplo battery. I did not have any difficulties installing the battery and battery life significantly improved FWIW, I just replaced the battery on my late 2013 MBP myself. I initially went with a battery sold by iFixit, but found that after conditioning it, the battery would discharge normally to ~60% and then immediately drop to 7%, which would then last for several more hours. Lots of other people saw this too. iFixit's customer support was great in
This is how Apple tests to get their battery life figures (it's a footnote on the product page): Wireless web testing conducted by Apple in October 2011 using preproduction 2.8GHz dual-core Intel Core i7–based 13-inch MacBook Pro units, preproduction 2.4GHz quad-core Intel Core i7–based 15-inch MacBook Pro units, and preproduction 2.4GHz quad-core Intel Core i7–based 17-inch MacBook Pro
The following lists detailed specifications of the current and previous MacBook Pro lineups. The models are listed through the following method: Screensize. Processor. Processor Speed. Release Date. Features. MacBook Pro | Core i5 2.7 GHz | 13 Inch | Early 2015. MF839LL/A.
