MacBook Pro i7 battery life

I discovered that after installing McAfee, my battery life went from great (10 hrs for simple processing tasks) to dismal (3 hrs - could literally see 1% disappearing every few minutes). I didn't check the Activity Monitoring but I uninstalled McAfee and the battery life returned to normal. I'm thinking that certain virus scan software are huge energy drains.

Hey everyone, I just had to return my custom configured 15" with 1TB. After numerous cases with Apple Senior Advisors and in store genius bar, my battery kept draining right out of the gate, just withe use of Chrome and surfing the web along with YouTube videos. With 90 mins of use on full brightness (which is the only way I like to use my computer) it went from 100% down to 69% with hardly any use and then when I brought it to the store, as they were running diagnostics which all came out normal, it was dropping 1 percent every few mins,. Decided to return it and I'm hoping they come out with a fix or perhaps wait for the next edition altogether. I really like the machine including the speakers are nice and loud, but 3-4 hours battery life on full brightness wont work for me. It's a shame, as I have a new iPhone 7+ and would like to sync everything across devices in a perfect world.

I promise I'm not trying to be snarky, but 69% after 90 minutes of Internet browsing and YouTube use is better than nearly any PC I've encountered, and better than quite a few Macbook Pro models I've encountered (including my own 15" w/nearly new batter and a 2TB drive).

Full-brightness burns battery no matter what. Battery life is calculated by manufacturers with pretty much every energy-savubg feature enabled. That includes screen brightness set pretty low.

Hi there, this is my first Apple ever (MBP 13" with touchbar) and I was very sad about battery life because it lasts for 3-4 hours only with no heavy usage but after the upgrade to Sierra 10.12.2 is much better. Even if not 10 hours.

Went into the regents street mac store in London UK today and on four different, identical specced MacBook Pro 13 inch touch bar laptops -

- all at 75% brightness

- 50% volume

- no open programs apart from safari showing the same homepage

On activity monitor with the charging cable removed and the battery at 100% charge, get ready....

One read 8 hours approx battery

One read 9.5 hours approx battery

One read 18.5 approx battery

One read 20 hours

Personally on identical machines, at the same energy settings running the same program and sitting idle, a small amount of difference is possible but 12 hours?!?!

Anyone else tested identical machines side by side. My one at home is 13 (possible processor upgrade to 3.3? 16gb ram), am returning it and apple can keep building me a custom one on their dime, until they get it right.

It appears the theory on differing battery suppliers is right. Make sure you check your machine against at least a few other machines.....

Consumer Reports tested several and got the same crazy variation in actual battery life. Their scenario is a bit different- they disable all battery-saving features in Safari and in the OS.

A couple of thoughts- first, Apple removed the "remaining" feature in a recent OS update specifically because there was a problem with the algorithm used that cause it to be totally unreliable.

Second- going back to the Consumer Reports testing- Apple sent then the latest beta and it fixed the battery consistency issues.

Well I just want to know one thing why did we all buy this new MBP 2016 ? I was told to dim my screen ?? to save bayyert ,when I dim it I can't see much ! Why it has such a great clear picture to dim your screen.There is an issue with the battery life hope that they will do something ,Replace the battery , Replace the computers or software issue .I think that something has to be done soooooooon .

Consumer reports for me I don't trust , one time they say battery problem and then they say something else .I care less all I know that my battery is running 4.20 H on a full charge and want my machine to be fixed .

100% of laptop battery life tests (any brand, and also including most electronics) are measured utilizing energy-savubg features, including but not limited to dimmer screen, reduced processor clock speed, and spinning down of any physical drives. if you want battery life that is anything like advertised life, you have to run under similar constraints.

Non laptop made will.cime anywhere near what you are looking for with brightness of screen set to max and heavy use. None. Not a brand or maker known.

I've been really upset with the battery life. I've read all the excuses and justifications for this MacBook Pro 15" with the TouchBar comparing it to other laptops of the same category etc. I was patient and waited for a patch to solve this, trusting Apple really does care for its products.

I don't care about excuses anymore. I'm comparing it to my 2012 Retina MBP. And it's absolutely embarrassing. I might get 4-5 hours out of this 2016 new laptop with writing in Word, answering emails in Outlook and playing music via BlueTooth in iTunes. This is my daily routine. With my 2012 MBP I could spend 8-10 hours outside of my office enjoying work without walking around with my bulky charger. Those days are over.

I don't have the freedom to go to any old coffee shop anymore, they must have power outlets now for me to be able to do my work. I'm forced to change the way I do my work by cruising along on 25% brightness to get an extra hour out of my laptop. On top of that the performance of running applications doesn't even seem much better than my old laptop. I truly thought this was going to be a step forward from my 2012 MBP which was already amazing, I regret replacing it. A true step backwards, I don't care what the reviews say -my colleagues, friends and myself know this not to be true.

Worst part is that Apple support just justifies this and doesn't see a consumer issue. I truly have patience and believe Apple tries to do the best for their customers, but this is a step back and not forward.

I've never been this disappointed with an Apple product and this change of heart about the quality of their products.

Here again my post was removed , Tough to post the truth here since this support is Apple and you can't post what ever I did earlier .So I am still facing the same problem with the Lemon I bought MacBook Pro 13" hope that this time they will not remove it as I am still working with a senior advisor . Yes many people are upset due to this same problem Short battery life.Cant post more hope this will not be removed ........

Hi Sam,

So, I did not read that you reset the SMC. I have a 2016 MacBook Pro 15", 2.7 GHz i7....I updated to 10.12.5 and reset the SMC. The problem was completely resolved. I went from about 3.5 hrs of battery life to almost 10 with constant use.

I read this fix on the forum, was skeptical, and then applied it. So far (1 week in) it's working well.

Be well,

TGF

What kind of web browsing? If you're playing a lot of Java or Flash games, that might do it, but even then 3 hours seems extreme. I can easily get at least double that on an older battery. You may want to contact Apple about this.
