Is it any differences in battery life between the different processors (MBPr late 2013)?
Is it any differences in battery life between the 2,4GHz i5, the 2,6GHz i5 and the 2,8GHz i7?
I'm planing on buying a macbook pro 13" but I'm a little bit uncertain which processor I should chose. I want as much power as possibly but if it's any significent battery diffrences, then I would chose battery over power. I've read that there is about 45 min diffrence between the 2,3GHz and the 2,6GHz in the 15".
I imagine that there are but since Apple makes no such distinctions, I suspect that the differences are not that great. I have not seen any reports or studies to that effect.
If battery life is of paramount importance to you, consider a Macbook Air. The advertised battery run times are significantly longer than the Macbook Pro.
Ciao.

Difference in battery life between MDR-ZX550BN and BTN200?
I am looking to buy either the MDR-ZX500BN or the BTN200. There are, however, some information that I can not seem to find or get confirmed anywhere. Therfore I hope that it can be sorted out here.
The differences that I can find (correct me if I am wrong) with the newer MDR-ZX500BN are:
- Texture (material?) on the earcups and hinges have switched (metalic and platic)
- Noice canellation (90%)
- Minor changes in button layout (button for anwsering calls)
- 10 grams heavier.
Another thing I noticed is how it claims a battery life that support up to 25 hours of music playback, while the older BTN200 calims 40 hours!
At first I wash shocked at the Idea that Sony would cap their own product like that (only 62,5% of the previous model's capacity).
I personally do not care for the nocie cancelling feature that much and would rather have the extra battery life (especially if that feature reduces the capacity as much as it has done in this case).
Then I thought it made more sense when I read that the 25 hours is measured when noice cancellation is ON.
Though, I can not find any information on how long the battery lasts when the nocie cancellation is OFF.
Some of the questions that this raises:
- These models look quite similar and the older BTN200 seems to be going out of stock soon, but the names are not very similar at all. So is MDR-ZX550BN really a successor to BTN200?
- Are there any minor or major differences, other than the ones that I listed before?
Last and certainly my main question:
- How long is the expected (up to) battery life on the MDR-ZX500BN when the nocie cancellation is OFF?Never mind.
I found it.
However, It says nothing about it on Sony's dedicated website for my country (Sweden).
I found it on the US website.
It can handle up to 29 hours of music playback with the noice cancellation OFF...
That is still less than 75% of the older and much cheaper BTN200.
Sony... this is not good.
While 29 hours is still quite good. The much higher price (effectively the double in stores, here in Sweden) and extra (even if it is minimal) weight, just won't cut it when your older version is way better.
I have not tried the noice cancelling feature on this particular model. But a lot of reviews says that is the weakest noice cancelling that they have experienced and that it is quite useless.
What the older BTN200 had going for it, was low weight, low price and the most astonishingly superior battery life. If something that makes a more universal impact on society, like an electric generator, was engineered to be as efficient as the BTN200 is among bluetooth headphones, I bet Sony would win the Nobel prize.
The successor MDR-ZX550BN has managed to be worse on all these points, is just generic and hardly worth the price it has.
I have decided that I will buy two (maybe more) BTN200 for the price of one MDR-ZX550BN. So that I may have a some spare ones, just in case Sony does not improve on upcoming versions.
If someone who reads this has any power to influence Sony's decisions on future models. Please make them realize this! -
The battery life between charges on my iPad has plummeted to about 2 hours. The guy at the genius bar said the charge should last about 10 hours and suggested it might be an app (unfortunately I didn't have the device with me and the nearest Apple Store to me is 2 hours away). Does anyone know of apps that cause heavy drains on power? It also does not charge when it is plugged into my MacBook while I am using the iPad but it does when I am not using the iPad. I mostly use the iPad to read e-mails, play Team Lava games, read books through iBooks or Kobo and the ABC Player. Any thoughts would be greatly appreciated! Thanks!
Restore is about the only option left, short reinstalling the whole thing as new.
Before you restore, go to I tunes and turn off automatic sync. Then plug the machine in. Upload any photos that you have taken with the pad into I photos, or where ever you keep your pictures. Then, in I tunes, transfer any purchases.
If any apps or purchased music get lost in the process, you can download them again for free.
You do not want to make a backup of what you have on the pad now. If you do, when you restore, you will simply recreate the same problem.
What you want to do is restore from a prior backup. Do that.
Then run the system status app and see what the CPU numbers look like. If they are ok, then you can start to re add apps until the problem shows up.
If this does not do it, then the last step is to set the pad up as new. Check the numbers, then add the apps and settings back one by one. While it is likely to be an app, it may be a setting somewhere. -
Optimizing iPhone battery life: Between charges and before replacement
FYI. An excellent iPhone battery care article by iPhoneAtlas.com:
Optimizing iPhone battery life: Between charges and before replacement
http://www.iphoneatlas.com/2007/07/09/optimizing-iphone-battery-life-between-cha rges-and-before-replacement/OK, I agree that is a completely false statement. The rest of the article is pretty good.
If you assume a linear decrease in battery charge for each full cycle (which it really isn't, but much easier to model in a spreadsheet). Then 80% of original charge after 400 full cycles is approximately 0.8% loss in battery charge per full charge cycle (again this is a simplification, stay with me). This means that after 400 cycles, you are at approximately 80% of your original total charge level. As stated by Apple.
So, extrapolating that out to EOL (end of life) which Apple assumes to be 50% battery charge, it would take approximately 1,000 full charge cycles for your battery to be EOL (according to Apple). It would actually be slightly less than that since it won't be a linear function.
For me, that's 2 to 4 years of use depending on whether or not I continue using the iPhone as much as I have this first full week. -
Battery life. The elephant in the room or is it just me?
So the trade-off against integrating the antenna into the case (at such cost) was to make room for a bigger battery, so we could enjoy longer battery life between charges on our shiny new iPhone 4s. Really? My 3G was nearly two years old when I traded up to the iP4, yet its battery discharged at a far slower rate than the 4's battery from out of the box. Is mine just fitted with a battery that came off the production line on Friday afternoon, or am I expecting too much from the new model given its enhanced capability (as compared to the 3G and bearing in mind I skipped the 3GS), which must be expected to consume more power? Whatever, I am disappointed by the battery life of the iPhone 4, yet surprised to read no mention of any battery issues in these posts, especially as battery life was supposed to be one of its selling points. The reviews also seem to confirm an improvement in battery life that just doesn't square with my own experience. Anybody got a view?
I'm surprised my battery is doing well although I have replaced my iphone for the 2nd time. But here is the result from the first replacement:
[IMG]http://i7.photobucket.com/albums/y256/kwopau/photo-7.png[/IMG]
comparing to what others have posted, similar stats but seems like mine only goes for 5 hours at tops or a bit over. So i took it to the genius bar, and this is why they replaced my iphone for the 2nd time.
Here is what I do with my iphone 4,
Basically I unplug it at exactly at 7 am, through out the day, I only check my phone every hour. Do some textings, check 2-3 apps every hour. of course i get phone calls in the morning and at night so during the day it's not a problem. From the time my phone is in sleep mode, and the time I wake it up, sometimes it stays, but sometimes I lose 1%, but then the moment I text or check few apps, I lose 2% more, which is fine i guess as the apps does eats small amount.
As seen on my stats, I can only get 5 hours of usage somehow. Even though the standby stats says 1 day 14 hours.
As for my 2nd replacement, even if it has similar stats (still on first charge so I have to drain it to calibrate the accuracty). I'll probably just keep this one, as long as the phone last the entire day is fine with me. -
I just bought my first iphone. I am so disappointed in the battery life of the iphone 5. Is this the norm for iphones? Are they working on a fix to this problem? Almost wishing I had bought something else.
Without knowing what battery life you are seeing we can't determine if you have a problem. Have you compared your usage to the Technical Specifications?
Talk time: Up to 8 hours on 3G
Standby time: Up to 225 hours
Internet use: Up to 8 hours on 3G, up to 8 hours on LTE, up to 10 hours on Wi-Fi
Video playback: Up to 10 hours
Audio playback: Up to 40 hours
Under normal use, unless there's a problem with your phone, battery life is comparable to any other smart phone and better than some. If you've never owned a smart phone before you will be disappointed with the battery life on all smart phones. You should expect to charge any of them daily. It's a mistake to think of it as a phone at all; it's a very powerful pocket-sized computer that can also make phone calls. -
What can I do to save my battery life with the new ios 7.3 update
I Loved the ios 7.3 update. My battery lasted for the whole day and I use my phone a lot. I did the ios 7.3 update yesterday and my battery life is horrible. With 2 hours into my day today I was down to 80% battery and I hardly used my phone at all. I love my iphone, but this update was a horrible mistake for Apple!
Thank God that I am not the only one who lost battery life in 7.0.3.
I haven't changed settings from 7.0.0 to now. So I am not going to change settings. With that said my brightness is always at about half or lower, depending on the ambient light. Bluetooth is always off. LTE has always been on since I bought the 5 last year. Wifi stays on, connected or not. So with all these settings as they are, there has been a huge difference in battery life from 7.0.2 to 7.0.3.
I could swear that I went from 100% to 83% charge while I slept for 7 hours. ***??? Really?
I'll test it out again tonight.
I am at work and I turned off LTE for s&g. And still saw 5% drop in 40 minutes with a 2 or 3 minute use.

Has anyone noticed a big drop in battery life from the iPhone 4 to the iPhone 4s?
In the 36 hours that I've had the iPhone 4s, the battery life is much worse than the iPhone 4. I'd like to hear if anyone else has experienced this as well.
iOS5 has removed the option to turn off just the 3G and have only 2G/Edge and WiFi. I used to do that routinely because I got much more reliable cell coverage in hilly San Francisco and it extended battery life between charges significantly. I only turned on 3G if I wanted to use the web while I was away from wifi or while on a call. The fact they removed this choice seems to have caught both Apple and AT&T staff by total surprise.
This is a problem in the UK as well as in the US and it isn't not carrier specific. It seems to be part of the iOS 5. I most certainly had it with my iPhone 4 and with iOS 4xx.
While the phone will revert to 2G if it thinks it needs to, that isn't good enough. I can't go a whole day (even half a day!) even on mostly standby. I've taken to turning off WiFi when I'm away from it because I can't turn off the 3G. I realize Siri won't work on 2G and maybe that is what has driven it-Apple's special, incredible new feature but if my phone has a dead battery it won't matter anyway.
Spread the news. Complain. We need to get this option back! -
I've just upgraded to the Iphone (4) update and now battery life of the poor is very poor (3 hours). Is there anything I can do to fix this?

Is there any character set translation facility between the database and th
We are upgrading a character based SQLforms version 3 application to forms6i running over the web against a 9.02 database.
Is there any character set translation facility between the database and the Forms server / web browser?
Our database character set is NEE..P4 (North European). However, the user needs to see the data in the BLT..P13 (Baltic) character set.
In the old application, users accessed these forms through a telnet client and this did the translation. For example :
The database character :
� (Unicode hex value = 00D0)
would be translated by and displayed on the telnet client as :
� (Unicode hex value = 0160)
A colleague of mine has done some experimenting. By changing the NLS_LANG registry setting to BLT..P13 in his oracle home and loading the Baltic character set for his Windows 2000 environment, he has been able to achieve the same translation in SQLPLUS.
However, we have been unable to do the same in a forms web runtime.Oracle automatically translates characters between the display CharacterSet and the database characterset
The statement
In the old application, users accessed these forms through a telnet client and this did the translation
worries me a little because it implies that the data you have stored in the database might not actually encode the characters that you think you've put in.
This aside you need to set you NLS_LANG parameter on the application server for the client side character set - if you are using the forms listener servlet architecture then this would be set in the default.env file. -
My MacBook will not turn on unless it's connected to a charger/power source. However, when it is on and charging, it says that it has 0% battery life despite the green light on the charger. How can I fix this?
Your battery has reached the end of its life. If you have a MacBook with the removable battery you can get a new third party battery fairly cheap on eBay.

How much real world performance difference would there be between the 1600MHz memory of a 4,1 Mac Pro and the 800MHz memory of a 3,1 Mac Pro? My main app is multitrack audio with Pro Tools. Thanks so much. The CPU speed of either one would be between 2.8GHz and 3.0GHz.
What are the differences.... firmware and build, there were tweaks to the PCIe bus itself. As a result 3rd party cards and booting is better.
Support in 5,1 firmware for more 56xx and W35/36xx processors. Also memory timing.
The 4,1 was "64-bit boot mode optional" and 5,1 was default. I don't know if there are changes but I assume so, even if it is not reflected elsewhere or in version number.
I don't know what the prices are but 2009, to buy one today, when the 2010 is $1800.
The 2008 of course was test bed for 64-bit UEFI and it sure seems even Lion and then ML are not as well engineered - outside of Linc who would be the least likely to have a problem.
I would assume 2010 has better support for 8GB and even 16GB DIMMs as well as for 1333MHz.
Nehalem family had only come out in fall 2008 and a lot of work went into making improvements well past 2009.
If you remember, there were serious heat problems with those and 10.5.7+ up thru 10.6.2 even with iTunes, audio, and hyperthreading and cores hitting and staying in 80*C range. That I assume was both poor code (sleep does not mean poke and ask constantly) as well as changes in SMC and kernel improvements, to work around. Microcode can be patched in firmware, kernel, by drivers and by code, but it is best when the chips and core elements don't need to be.
If someone is stretched, and can get 2009 for $1200 it might be a fine fit. That year offered the OEM GT120 which isn't really as nice and matched for today both OS and apps that rely on a GPU. And for odd reasons two such 120's don't work well in Lion+ but that is probably minor. Having the 5770 is just "nicer" though.
There are some articles about trouble booting with PCIe SATA/SAS/SSD and less trouble with 2010. Also support for graphic card and audio I think was one of those "minor" 5770 related support issues. But shows some small changes were made there too.
I wish someone would come out and pre-announce DDR4 + SATA3 along with PCIe 3.x (for bandwidth and more power per rail) along with say Ivy Bridge-E socket processors was going to be this summer's 3 yr anniversary and to replace the 2010 designed motherboard. But that is what is on Intel's and others drawing boards simmeringn in the pot. -
Core i7 Haswell's - Significantly Less Battery Life Than The Core i5's?
Is anyone with a Core i7 macbook air, new one with the Haswell processors, seeing less battery life than the same system with a Core i5?
Long story short, I started out with the Core i5 and 4gb ram (store bought) and decided after a week to go with 8gb ram and figured I'd up the CPU to the i7 as well and ordered from Apple.com.
The original Core i5 REALLY WAS getting upwards of 12 hours on battery; this Core i7 is more around 6+ hours. I took it to my local Apple store, they tested it out, showed everything hardware wise was fine and suggested reloading to factory...Done (nothing installed/change from factory; NOTHING)...Same issue...
I know, and expected, to get less battery life with the Core i7, but almost 50% less? ***?
Anyone else seeing this?
Thanks!
ScottSeveral have reported same, contrary to vociferous statements by others to the contrary, since the I7 idles at a low power consumption, and bursts data quicker than the I5
You are not supposed to be getting that, if as you say you have NOTHING installed at all, just factory. However that rating is for minor web surfing and word processing etc.
More important than longer batt. life to me are these stats. Id return it and get your orignal I5 13" ..but get 8gig of ram.
Geekbench: i5: 5868, i7: 6287 (+7%)
Handbrake: i5: 12min12s, i7:12min5s (-1%)
Cinebench: i5: 11.13fps, i7:11.54fps (+4%)
iMovie: i5: 5min1s, i7: 4min56s (-2%)
PhotoShop: i5: 68.7s, i7:57.4s (-17%) <<<<only "real" improvement area of the I7
Final cut: i5: 2min7s, i7: 2min 4s (-2%)
But your I7 experience is not supposed to be normal however,.....despite many others reporting same.
Love my new macbook Air, ....sounds like you loved your original I5 13" , .....seems youve come full circle. -
To many different suggestions as to battery life of the MacPro. Is there one way to keep your battery life, do I keep it plugged in to AC or do I not?
To be honest, I would only plug it in when necessary. On my older 2009 MBP, I plug it in at night and it lasts me a solid 5-6 hours, if it needs to be plugged in during the day, I usually do it with about 2-3 hours left.

I am very disappointed with the battery life I am getting out of my Iphone 5S 64G. I charge it every night, and would be lucky to make 15 to 20 minutes of calls during the day and yet I am lucky to get much more than 12 hours of life out of the battery.
I have to make a conscious decision not to use it to avoid it running out on me. I had it back to the Apple Store last week and they ran diagnostic checks on ot and said that the hardware was within specs.
They replaced the software as it was showing that Springboard had crashed on several occasions. The other problem I was complaining about was that at least 2 or 3 times a day, the phone would refuse to wake up when I hit the home button. It would take sometimes up to a minute of pressing the button before anything would light up. The guy at the Apple store said that this was caused by Springboard crashing and that this would also be what is reducing the battery life.
I did notice that after they replaced the software, the waking up problem appeared fixed for a few days, but the battery life had not improved. Now the waking up problem is starting to return.
It is very annoying and somewhat embarrassing when you are with a client and go to make a call and your shiny flashy new Iphone 5 won't even light up. Especially when you have to borrow your clients Nokia....My best bet would be to restore the phone. Back it up to itunes, and then reset it Factory settings. This way, any corrupt software will be removed, and you can start fresh. Make sure you back it up first. By the sounds of it, you are using the phone for business and probably need the data from it. Hope this helps!
