96% Battery and only 3:44 Hours ??

[DeltaMac]

OK, I read what you said, but you have very little information to go on, just the software indicator that estimates how much battery is left.
How accurate is that - really?

When you tested the battery for actual duration during your normal use - how long did it go on a full charge?
Did you try again after using it for a couple of days?
(I doubt that you stood there in the store, trying the battery out ... 😀 )
Wouldn't the only way that YOU can tell how long the battery lasts, is to actually use it?

The example that you saw in an Apple store is really an unknown - you have little idea how it is configured, for example.

is that for the 2016 15" rMBP that you are talking about ? The one that I am talking about I saw it in an Apple Store.

What you saw was just the reported estimate. What I am talking about are real tests. Yes, its the 2016 15" MBP

is reported estimate showing on the screen does it vary with the Actual one ?

An estimate is just an estimate. It's a guess that the system makes based on history and current consumption and other factors. It can be bugged out, it can be inaccurate or it can be plain wrong. You obviously need to look at the real world performance and not what OS guesses for you.

is there any app that shows total amount of time on battery power? like how the iPhone tells you usage time. Only apps i found just show estimated time and nothing about how long its been off a charger for.

 

[azntaiji]

I think it's important to note that the "time remaining" number is not very accurate. It's based on how you are currently using your MBP - i.e. if you're rendering on FCP, it's going to be really low. Once you quit the app and go back to regular web browsing, that # will skyrocket.

Better to do reactive monitoring/analysis of your battery than proactive. i.e. run it till the battery dies, then look back and see what kind of battery life you got based on your usage.

I have the 13 inch 2016 no touch bar. Interestingly if I turn off bluetooth even though nothing is connected to computer my estimated time almost triples. It goes from 3 hrs to 14 hours.

Depends on what background processes were running on that machine. At the beginning a MBP will not dleiver 10 hours as processes like spotlight indexing the computer, eat a lot of resources.

But there definitely are people who reach the 10 hours as advertised, else Apple will face a class action lawsuit very quickly.

Please point me in the direction of these users who can confirm they used their new MacBook Pro for 9-10 hours. I have yet to read one article or view one review showing the MBP lasting more than five hours. The average with normal use (no streaming video/music) seems to be around 3 hours.

Does it only "show" 14 hours? Or have you actually used your laptop for 14 hours straight? The estimated time is not accurate. My Retina MacBook says I have 8-9 hours of battery life all the time, then it lasts about 5-6 hours using the Internet and MS Office.

£2500+ and i get a whooping 4 hours... this was a screenshot earlier, when i had one website open

The screen brightness of my 15" MBP 2016 has a huge impact on the battery life. If set at 75%, (12 clicks from lowest setting per an Apple bulletin copied on this forum) I am on track for 10 hours. Battery drains quickly at higher settings.

 

[gngan]

So Guys should I take the plunge in buying one or not I am scared that If I buy one and that might just not give me the 9-10 Hours battery.

I doubt it will give you 9-10 hours. If you are only basing that then don’t buy. You will just end up returning it and whine about it. Good luck with other laptop with advertise battery life.

 

[Krme Papak]

So can someone please tell me what all do I need to get 9-10 hours of battery ? Like things to do and not to do !!

Sleep mode 🙂

Same problem! Contacted support. Getting a replacement!

 

[heymonroe]

Brightness plays a huge role. Also if you haven't reset pRAM and SMC you should try that before going the replacement route.

That's great your estimate is showing 9 Hours of battery that's impressive. What have you kept your bightness on ?

is resetting pRam and SMC a mandatory exercise even if the machine is just bought ? What is pRam and SMC ?

Today I saw another 2016 15" rMBP with a fully charged battery 100% just showing 3:05 Hours of battery.

Which means nothing!

 

[capelesshero]

Like many have said, power consumption varies with the applications that are being used. Even the air temperature affects battery life! I unplug my MacBook Pro after a full nights charge and use it throughout the whole day, boot up windows 10, switch back OS X and so far I have only ran out of battery once throughout the day. I use apps like safari, word, excel, and autocad sometimes. There is a LOT of criticism for this notebook but I am very pleased with it and plan on using it until it runs no more. My 2010 MBP is still running strong too!

 

[augustya]

How is it that the same machine 2016 15" rMBP in the Apple Store which with 100% charging was saying 4 hours of estimated battery is the next day showing 10:30 hours of estimated battery the same machine with the same charging status ? Which is 100% !

 

[DeltaMac]

Because the number is an "estimate", and can vary, sometimes wildly, when YOUR setup, the settings that you have in use, the apps that you have open, changes that you make to various hardware settings, such as screen brightness, etc - all of those can directly affect the "estimate".
One way that can help you is to make those changes to the system that may be recommended to give you better battery life, and watch as that estimate changes. It may change immediately, or might take several minutes, depending on what is happening with your system.

But, to answer your question about which estimate is correct for 100% - the answer is "Both"
Keep in mind that the estimate is a real-time estimate (what is happening right now)
High drain, then the estimate can drop dramatically, Low drain (or minimized), and the battery life estimate will climb up.

The real question is: How long does the battery actually last in real use - the way you use it?
(hint: you can't answer that question by monitoring a sample system in an Apple store. You have no idea how it is set up, or even how often the operating system is re-imaged. I think that the display systems are frequently re-imaged, perhaps several times per week - mostly to clear out customer-caused "cruft"

The general consensus is that the battery life is worse than last year, go figure...

We were all expecting atleast a modest increase given more efficient processors but Apple instead is obsessed with thinness.

Can anyone help me out?
difference between macbook batteries serials ?
my battery is model A1331 020-6809-A ...... Can i fit an A1331 020-6810-A? will it work?

thanks.

Looks like a good swap, as the two numbers are just different models of the same battery, maybe different manufacturers - but the batteries should be the same.
If you purchase from some dodgy retailer, and get it really cheap, maybe less than 80$US, then you want to try it out, and hope that retailer has a good return policy 😀 )
(Cheap batteries are almost never a good buy 😀 )

 

[MarcBou]

I think what's wrong is the indicator. Once I checked at 90% and said 3.45 hours left of battery. Then next day was on 79% and said 7.20 hours left. Both times I was just using a couple of tabs in Chrome and spotify.

The battery life indicator it's what's messed up.

Thank you a lot bro! yep actually worths $90, but thank you for clearing me up that question! 😀😎

Like many have said multiple times, it's best to completely ignore the estimates. I'm my experience with the 2016 MBPt it has never once been accurate. Watching Activity Monitor's "time on battery is much more telling.
