2015 13″ MacBook Pro owners complain of lags in the UI, and poor battery life

by AshwinApril 7, 2015

Last week we reported about how the 12″ Retina Macbook had scored rather badly in a benchmark test, the rsults of which, ranked it on par with the 2011 MacBook Air.

And now it appears that the 2015 13″ MacBook Pro isn’t faring well either.

Apple launched the 13″ MacBook Pro last month, but some users of the 13″ device have reported that its performance is terrible. Reports have surfaced which claim that the device has choppy performance, and the lags occur even in basic tasks like Mission Control, switching between windows, opening new windows, scrolling web pages, etc.

Instance 1:

One user at MacRumors forums has declared that the device has “the most significant lag”, of “any laptop on Yosemite” he’s ever used, which includes a 2010 MacBook Pro. The user who also owns a 2013 MacBook Pro, says that his 2 year old device is super smooth with several third party apps installed, his forum post says.

In spite of trying a PRAM reset, the lags returned on the 2015 device, which eventually led him to give up, and return the device to Apple.

Instance 2:

The second user says he experienced lags almost everywhere, and even PRAM resets, or lowering the display settings didn’t solve the issue, but turning on high-contrast mode, made it a little better. Another complaint he had was the extremely poor battery life which he experiencing. The device could only manage 6 hours of web browsing with just one tab open in Safari browser, against Apple’s promised battery backup time of 10 hours for browsing.

So what is it that makes the 2015 13″ MacBook Pro lag?

Let’s a take a look at the technical Specifications to analyse the cause:

The device flaunts a 13.3-inch Retina Display which has a resolution of 2560-by-1600 pixels with a pixel density of 227 PPI.It runs on a 2.7GHz/2.9Ghz dual-core Intel Core i5 processor. It has 8GB of RAM, and has an Intel Iris Graphics 6100 GPU. It also has a 720p FaceTime HD camera, and 128/256 GB of internal storage. The 2015 MacBook Pro weighs just 1.58 kg, and measures 18 x 314 x 219 mm.

The device is WiFi and Bluetooth capable, and has Dual microphones and Stereo speakers. It has several ports: Headphone, MagSafe 2 power port, Two Thunderbolt 2 ports, Two USB 3.0 ports, a HDMI port and an SDXC card slot.
Like the 12″ Retina MacBook, the 2015 MacBook Pro also has a Force Touch trackpad, which has sensors to detect pressure as clicks. It also features a full backlit keyboard. The device runs on Apple’s latest operating system, OS X Yosemite, and has a battery backup of up to 10 hours  for wireless web, and up to 12 hours iTunes movie playback. The 2015 13″ MacBook Pro costs $1,299.

On paper it looks to be a great device, but the reports from users are disconcerting. Both users have come to the conclusion that the problems aren’t isolated. Of course, it is possible that they may have had the misfortune of receiving defective units.
