Mine is about the same as it was in 4.3.2, 4.3.1 and 4.3. But 4.3 was better than 4.2.x.

IOS 8 update causing drastic decline in iPhone 5 battery performance.

Since the IOS 8 update, my iPhone 5's battery performance has drastically declined. Anyone else having this issue?

does the battery monitor not tell u what is using it? go into settings for it.
dunno where your based but in the uk we have 4g but not everywhere so with 4g enabled on the phone it keeps searching for a better signal so turn that off. Try turning off mobile data when your not using it to see if that prolongs the battery. Like an issue I have if there is a data connection issue then the phone will be doing a lot of "trying to connect" and using up battery fast.

Wat is best ios for iphone 3g as far as battery performance is concerned?

wat is best ios for iphone 3g as far as battery performance is concerned?

According to tests done in the wild iOS4 lasted 5% longer than iOS3 (about 10 minutes). Not much of a notible difference. Best bet is to upgrade your phone. A 3Gs on iOS4 ran more than 30 minutes longer on the same test.

Does ios 7.1.1 improve battery performance ,also what is its effect on the speed of iphone 4s????

Does ios 7.1.1 improve battery performance ,also what is its effect on the speed of iphone 4s????
if it increase battery i want to know if it reduce the iphone speed ,as after ios 7.1 my iphone got more speed but the battery drainage increased

Tx modular, I mean by speed the general performance of iPhone which optimized after iOS 7.1 but I am afraid to update to iOS 7.1.1 not to lose this perfect performance but also I need battery life optimization

Iphone 6 battery drain ios 8.1.2

Tormented by Battery Life
IOS 8.1.2 upgrade caused it
iPhone 6 64GB Grey battery constantly drains now, from full charge at 7 am it will die around 2 pm with minimum or no use.
It even drains while on standby, no serious culprits the phone was setup as new and all apps are upto date downloads form app store
The phone and apps worked fine before it,
Post update did the following so far
Soft Reset
Hard Reset with Restore all backup from cloud
Hard Reset with Restore all backup from pc
Restore again from pc with and without the restore backup
currently using a new setup with data synced once with icloud login
I have following tweaks already from various battery performance tweaks
Location Services to minimum (Google maps), no system services enabled
Background app refresh disabled
Reduce Motion is on (parallax effect disabled)
Notifications to minimum
Auto Brightness off and brightness is 25-30% from manual selection
Wifi and Bluetooth is usually off
Carrier Phone signal is usually ok but shows low signal in small percentages across email, phone but not too much its like 5%, 6% variants
iCloud is off
Autoupdate of apps is off
mail is on manual sync every 30 mins (4 accounts)
Can't see any obvious app which will cause this
Generally the drain increases if I use a heavy app like Google Navigation, or Marvel Content of Champions, gets hot too when using a heavy data app and battery can run flat in plain 1 hour of use
The full charge of the phone also takes longer and then discharges (with some emails (not on auto fetch), small use of whats app and 1 phone call) within 4-5 hours with tweaks 1-11 in place
Can anyone help, I have booked an appointment with genius but what if they say its just software even though I tried everything
Any genuine issue here?
Please don't redirect me to tweaks etc I have almost tried every blog out there on tweaks on battery and almost tried all combos

Addendum
Last night charging for around 3-4 hours only charged a dead phone by 55% then left it to charge overnight
Today the battery dropped from 6:15 am full charge to 53% at 10:38 am at time of writing this with
1 phone call out for 30 secs
1 incoming missed call,
Whatsapp fetched around 10 msgs
Email fetched around 20 ermail from 4 accounts but not viewed yet on phone

What does Apple mean by "For best battery performance, leave your device connected to a power source until the restore is complete."

I just recently returned an IPad air and exchanged it for another. I first set up this new one as a new IPad but then deleted all content and settings right away (since I wasn't getting the progress I had made in apps and games) in order to restore it from my previous IPad Air. I then checked after on how to backup via icloud and saw this line under the subtitle of how to restore from a backup, "For best battery performance, leave your device connected to a power source until the restore is complete." What does Apple mean by "for best battery performance"? Im just a bit worried of issues.
p.s. And yes I did have it connected to the power. And the ios is the default ios for new IPad Airs.

Welcome to the Apple Community.
It only means you should restore whilst it is connected to a power supply, so that your battery doesn't go flat during the process.

IPhone 4S Poor Battery Performance SOLVED!!

iPhone 4S Poor Battery Performance SOLVED!!
I found the issue with the iPhone 4S battery performance.
I bought 2 iPhone 4S models on the first day. One for my wife and one for me. The strange thing was that mine would kill the battery in 4-6 hours and ran VERY WARM to the touch. My wife's phone worked great. It was cold to the touch. She would forget to charge it at night... and the battery performance was great... even better than our prior 3GS models.
What was the difference? I have my phone connected to Exchange for my corporate email. But exchange is not exactly the problem. The issue is in Notification Center. For some reason, I had hundreds of calendar reminders that kept refreshing on notification center. Furthermore, the reminders would flicker between the time remaining and the start time for the event at such a fast rate that it could not be read... (clearly a bug)
What is the solution? Go to Settings>Notifications>Calendar and disable Notification Center. You can still have the "alert style" set to Banners, or Alerts and you will still receive notices about your events, but it will not BUILD a summary in the Notification Center drop down screen. This is where the BUG exists. [Oddly, this does not affect my iPad 2, but is an issue for iOS 5 on the iPhone (different builds, maybe?)]
So, it appears that Notification Center has an endless loop in collecting the calendar events from Exchange and this is burning up our 4S batteries. Once you stop the madness from Notification Center, your iPhone 4S will perform as advertised.
Enjoy!

Iphone 5s battery performance

I am very happy with my iphone 5s battery performance when it is on ios 7.0.5, standby time can reach 20 hours with usage time of 4 hours after every full charged. But, after updating to ios 7.0.6, the battery life became very poor, even now with 7.1 also same problem!!
Please, i want to have the previous battery performace.

One thing to check is Settings > Bluetooth. The update process turns it on. Turn it off if you don't use it.

Battery performance worst after 5.0.1 upgrade

Battery performance worst after IOS 5.0.1 upgrade. I Did upgrade my iphone yesterday and I notice the battery has ran out faster today after 6hours in standbay and 2.30 hours of use. Hopping to get final update that fix this issue.

ok, do you have a technical support question?

Battery performance reduced abruptly

I just bought my MBP 15" with a 2.8 GHz intel core i7 processor, 8 gb in ram, and 500 gb hard drive in december 2010 (6 months ago) and it worked perfectly until after a couple of months later. I decided to restore it and install windows 7 with bootcamp, but after restoring OSX, battery life performance was all of a sudden reduced abruptly. It only had gone about 80 cycles and now battery was not lasting more than 4-5 hours at 5 %. The battery icon on finder went totally crazy, going from 10 hours to 1 in just a second no matter the charge percentage; every time i checked it, it showed a different time. I calibrated it at least 3 times before deciding to go to a service center.
I took it to an authorized apple service establishment to claim my applecare plan. Neither the battery nor the MBP showed any problems and apple would only blame it on usage, but the service guy did detect something wrong, so he kept trying and after A LOT of scans and tests, battery finally showed a problem, which allowed him to order a replacement battery.
When i got my device back, I started noticing the problem was not really fixed, so i kept monitoring the battery performance only to find it was still going wrong. This time I did not bootcamp windows. I finally convinced myself that i was being too tough with my MBP after a few calibrations until battery started to go even crazier than the first time, plus this time, also the hard drive was showing problems since it would take literally about 10 minutes to start and it would never turn off unless I forced it to do so. I took it again to the service station where they ran test and got me a new battery replacement and a new hard drive.
This is my third battery in less than 6 months, and now I am starting to detect those same symptoms in the battery performance that in the past. This time i decided to take it to technical service before it totally crashed like past times, but since it was a different guy who checked it, he did not detect anything and did nothing to it. I am pretty sure my MBP is totally sick since this time, with only 20 cycles, battery is lasting from 1 to 4.5 hours with minimum usage, but no one seems to know whats wrong with it. I tried asking for a whole MBP new replacement with my applecare extended warranty, but they just keep blaming it to the usage i give to my device (which by the ways has been kept to minimum since the last time I got it back)
Please any help from anyone? I am kind of desperate and disappointed at this point.

I'd be concerned that it might be some other controller component or a bad logic board if other parts are repeated failing, maybe something else is causing them to fail.
I'm probably flirting with the terms of use here, but I'd recommend trying out small dog electronics in vermont for your repair (google them, don't want to post a link to risk losing the post before you get to see it). I get no compensation from them, I'm just a fan of their work. they're very thorough and if you explain the whole problem and what you've done before, they'll go above and beyond to test and retest after they do work to confirm they've fixed things. they have a mail-in service option too so it doesn't matter where you live. if you haven't resolved this yet, I'd check them out. as an independent apple reseller and repair center, they seem to be more of a consumer advocate than just a fixit genius bar looking to resolve an immediate problem and move on to the next. that said, I've had great experiences with my local genius bars. I'm just saying that maybe someone like small dog would have a better chance to test, fix, and re-test over some time or a few days to confirm a fix before giving it back. I'm thinking it's more than a battery if other components aren't behaving as well. I'm not a tech so I can't suggest what to try, only where I'd try next and expect good results.

Decreased Battery Performance when using SL. Apple states I am alone..

This thread is mainly aimed at people that are using a mid 2009 unibody MacBook Pro 13" or upwards that came pre-installed with Leopard. Since upgrading to Snow leopard have you noticed a significant decrease in how long the battery lasts while using the machine in the same fashion?
Am I alone? I first reported this issue to the Dutch customer service team back in October 2009 and since then have fought it all the way to make Apple admit that there is a problem with a minority of customers. To this day according to executive customer relations, I am the only person who has reported this issue to them. I find this hard to believe as there is a mass of information/threads/blogs etc on the internet with many people complaining about the same issue.
The following is an email I sent to the [email protected] email as a last resort.
Dear Steve,
I am writing to you as a last resort hoping that my complaint will be dealt with professionally as I have actually given up all hope with the Apple customer service. I do not expect that you will personally read this letter but I just trust that someone will care and pass this to someone that will treat my complaint seriously as I really am losing all faith with Apple.
I purchased a brand new Macbook Pro 13" mid 2009 model at the end of June 2009. Around 3 weeks after I purchased the machine I received a message from Apple stating that I was eligible for a copy of Snow Leopard as it was compatible with my machine and because I had just purchased a new Mac. I upgraded the Mac to Snow Leopard without any issues. It wasn't until a few weeks later that I noticed a massive reduction in battery performance. When I ran the machine on Leopard I would easily get the advertised 7 hour battery life while doing basic web browsing with all the battery settings set to the Mac default recommended settings. On Snow Leopard I would not get anything more than 4 hours completing the same tasks.
I contacted Apple about this and was provided with the following reference number XXXXXXXXX I was basically told that I should monitor what I was doing etc and try using the screen on the lowest setting to see if this would improve the performance, it did not. I am a busy man and work in graphic design so unfortunately I put up with the battery issue until my Hard Drive decided to die in April. I contacted Apple again about this and was again provided with a reference number XXXXXXXXXX this time I was asked to do various steps to help fix the machine which did not work. Eventually I had the machine booked in for repair. When the machine was booked in for repair I also stated that I would like the battery issue addressed once and for all as I still only get around 4 hours charge. I was told this would be looked into. After 2 weeks of having no machine (and losing out on work) I received my Mac back with a new Hard drive installed as the old one was corrupted. I asked the Apple employee if my battery had been addressed and it had not. I refused to except my machine back as the battery issue was not resolved. After another 2 weeks of not having my Mac (more loss of work on my account) I received it back this time a new battery and motherboard had been installed.
I returned to my office and reinstalled Snow Leopard, my Adobe Master Collection and charged to 100% I then tested the machine on battery. Again I received no more than 4 hours using BELOW recommended Mac battery settings. I contacted Apple again by telephone (another 0900 number call at my expense) and was messed around left right and centre. The employee on the telephone did not know what to do so transferred me to one of the Mac level 2 agents. I have never been spoken to so rudely and was even told that the only way I could expect 7 hours battery life from a MacBook Pro 2009 model is to use it with the lid closed. Ridiculous hey? I was also even told by one of the previous customer service agents that I could try using the machine with the battery disconnected. Even more ridiculous considering it is a unibody model.
At this point I started doing research on the issue and found that I was far from alone with the battery issue. I have found numerous people suffering from the same issue. Below are a few links containing the same issue.

At this point I decided to try something different, something that was not recommended or mentioned by any Apple employee, sales or technical. I decided to reformat the HD and install Leopard back on the on the machine. I then completed a battery test and low and behold my 7 hours of battery life were fully back. I think this can safely say that the issue is clearly with the OSX and not the hardware.
I then contacted Apple customer service by phone (more 0900 numbers at my expense) I spoke to a senior Applecare advisor called XXXXX XXXXXXXX and explained my issue in full. I told xxxxxxx that I wanted this matter looking into and that I wanted a machine that would give me what is advertised using Snow Leopard, as know where on the Apple site or in the Snow Leopard documentation does it state ' Expect to lose 3 hours '
I provided xxxxxxxx with a system info file and he sent it the Apple engineering team. A week went by and I received an email from him with the report from engineering. Engineering basically blamed it ALL on 3rd party applications, they even blamed it on the weather widget stating that it is constantly updating and will drain power. My remote access software was also blamed which was not even running in the background.
1: The weather widget updates when you select it not constantly.
2: The weather widget is by DEFAULT installed on a machine so thus would be classed as an Apple product in my opinion.
That evening I decided to reformat my HD and reinstall Snow Leopard. This time I installed ONLY Apple software updates and nothing else. I then tested the battery again (getting very boring now) using the same settings as previous tests. This time I managed to have 4 hrs and 15 mins. Just 15 minutes more than what I had previously had. I then contacted xxxxxxx again and provided him with another system information file from the clean install. I explained that I had tested this with just the airport on and basic web browsing on various sites (my exact words) Another week went by and I received a call from xxxxxxx with his report from engineering. He said that Engineering wanted to know if I had tested this with basic web browsing or sat on Youtube or other flash based video streaming sites for 4 hours as this could reduce the battery life.
As you could imagine I was furious. I repeated myself to xxxxxxx about my tests and was told that he would go back to engineering. I received another call from xxxxxxx stating that engineering are looking into it. I asked how long it would take for an answer on this and we agreed on a 2 week time frame. It is now over 2 weeks and I have sent 2 emails to xxxxxx and still have not received a reply.
This issue has been going on since October 2009 when I first reported it. We are now in July 2010 and I am still suffering with this, as you can imaging this is unacceptable and not what one would expect from a company like Apple. My complaints summarized are below, I believe the obvious speak for themselves.
1: There is no disclaimer on the Apple site stating that Snow Leopard will decrease the performance of a battery on a machine that did not come preinstalled with Snow Leopard. Neither is this information provided on the installation PDF instructions that come with the Snow Leopard disc.
2: If there were such a disclaimer on the Apple site then why would I have my battery and motherboard replaced by the Apple repair team when there was clearly nothing wrong with them in the first place. Why was I never told this by any agent on the phone or in the Mac store? The answer seems clearly that this information is not available to the public or to Apple staff which is a big waste or my time as well as theirs.
3: I have missed out on work because of having my Mac in for repair for a total of 4 weeks. As mentioned above there was clearly no need to have had the battery or motherboard replaced.
4: I have spent money calling the 0900 numbers on numerous occasions simply getting passed around from Apple employee to Apple employee and still have no answer to my problem.
5: I have wasted so much of my own time clean erasing my hard drive including zero out of sectors and reinstalling operating systems, not to mention other software and Apple updates. All of this comes to many hours of total wasted time at my expense when I could have been working.
Where we stand now is that I am on the verge of taking legal proceedings with the Dutch Consumentenbond as this machine is not suitable to run with the Snow Leopard OSX when Apple advertise that it is.
I expect either a full refund of my MacBook Pro 13" mid 2009 or an exchange for a Macbook Pro 13" that comes with Snow Leopard preinstalled with the disc in the box. I also expect to be compensated for my loss of time, money I have spent on the phone to Apple and the loss of work while the machine was in for unnecessary repair.
I am really at the end of my patience with this issue and feel that I have been much more than fair with my reports, honesty and patience.
I trust to hear from somebody soon regarding this issue so that we can finally put it to a close once and for all in a professional manor.
Regards
I received a phone call within 14 hours of sending the email from executive customer relations. They came back with new information from engineering but did not think it was acceptable as engineering were now blaming my battery decrease on the assumption that my apartment might be too hot this causing the CPU to run at a higher temperature making the battery decrease quicker. We both agreed that it was an unacceptable answer.
The day after I received another call from them stating that engineering had now finished tests and came to the conclusion that when testing on Leopard and Snow Leopard on the MacBook Pro 2009 there was no difference in battery run time whats so ever. I found this hard to believe so asked exactly how the test was conducted. Was it conducted in the same fashion that I had spent the last 9 months talking about. ' Using below default energy saving settings with only airport on while completing basic web browsing '???
They confirmed this was not the case, engineering had basically turned the machines on, turned the screen right down to 1 bar and left them on screen saver over night. As you can imaging I was speechless (for a few seconds)
Apple seem consistent on NOT admitting that there is an issue with battery performance for a minority of customers. As is stands now engineering in Europe have now passed the case over to engineering in the US for further ' in-depth ' tests.
I know there are people out there that are suffering the same issues as myself and I welcome you to please contact me with your experiences. As the more of us that complain about this make it harder for Apple to deny this and brush it under the carpet.
Please feel free to reply to this thread or email me directly on [email protected]

Please, nobody's going to waste their time reading all that! I don't know what you possibly could have said about this issue that took up so much space, but if you can't express it more concisely, it's probably not worth reading.
I have used SL on both a unibody MBP and an older MBP. On the older MBP, when I upgraded from Leopard to SL, I got a noticeable increase in battery life immediately. I have no such comparison on the unibody MBP, since it had SL installed to begin with, but I'll put it this way: I haven't come close to running out of power on it. I used it once for about 4 hours and still had more than a 1/3 charge. I could have easily used it for another couple hours, at least. And this was with a 17" MBP, which uses more power than your 13", and without much in the way of battery-saving going on. (Screen at full brightness, AirPort on and in use, Bluetooth on, etc.)
It's difficult to say that SL is the problem when it clearly isn't for everyone. What your problem is, I don't know, but maybe if you posted a more concise question you'd get some answers.
I think ..
This thread is mainly aimed at people that are using a mid 2009 unibody MacBook Pro 13" or upwards that came pre-installed with Leopard.....
at the beginning of the thread I made it pretty clear, if you are not affected by this then I'm happy for you, but then the thread is clearly not aimed at you. I can guarantee that I have tested this exactly the same way I did with Leopard and there is a significant decrease. I also know there are people out there that have gained battery life but there have also been many threads containing people who have lost battery life.

What's wrong with my iphone 4 battery after ios 7 ?

Literally:
What's wrong with my iphone 4 battery after ios 7 ?
I've tried all tuning tricks - nothing changed.

This is not a current feature of any iphone, it never has been! I've heard that there are apps in the app store that allow you to transfer contacts but i'm not sure about anything else! Again you would need to look in the appstore, but again it will be very specific to that app if there are any at all!

10.6.4 shorten my battery performance

After upgrade to 10.6.4, I found the battery performance does not perform as before.
It used to have 9hrs (displayed in menu bar) that I can work with.
However, after 10.6.4, the battery indicator shows 7hrs only at same working environment (safari, iwork, msn, endnote, and some small research software, and 50% screen brightness).
Is this my self-suspicion or it is the problem comes with 10.6.4?

FWIW, I have not noticed much difference in battery life with my white 2008 MacBook after updating it to 10.6.4.
I don't usually have the menu bar icon set to display time remaining because as noted by another poster it is just an estimate that changes often depending on what I'm doing. For example, with a fully charged battery, I see about a 5 ½ hour estimate with no apps running but as soon as I start Hulu Desktop & connect to its servers over Airport, the estimate almost immediately drops to about 3 hours & declines from there. But if I quit the app, the estimate jumps back up. If I then let display sleep kick in for a minute or two & then wake the screen, I immediately but briefly see an estimate of over 7 hours! For that reason, I leave the icon set to display percent of battery power remaining.
This behavior has been about the same since I got the MB with Leopard installed & remained so through all versions of Snow Leopard, 10.6.4 included.
One thing to check is your battery's condition. (As described in Mac OS X 10.6 Help: Battery conditions, this is very easy to do with Snow Leopard.) If it doesn't say "Normal" it may need service or replacement.
Another thing to check is if all your power related system preferences are still set to what they were before applying the update. Sometimes an update will reset one or more of them to a default or unexpected value.
Also, it might help to share battery info like charge cycle count, a rough indicator of how much the battery has been used & its remaining capacity to hold a charge. See Determining Battery Cycle Count for more about that. FWIW, my 2008 MacBook isn't used much & has only gone through 58 charge cycles. As recommended in Apple - Batteries - Notebooks, I occasionally let it discharge completely.

Battery performance on vista v osx

Hi there
I have a macbook which runs vista and osx and am finding that the battery performance on vista is pretty poor compared to running osx - has anybody else experienced this and what would be causing it?
cheers

try turning off all the eye-candy on Vista (that means turn off Aero), it will save your battery, it's because it's also making your CPU/GPU work harder.

How to properly use iphone 5s battery performance

Will my iphone 5s battery performance still be at maximum (full performance and capacity) if I charge it at any percent like 57%? I always thought charging it any time will weaken the battery life so i'll have to charge it more frequently as time goes by.
Also, is charging my iphone 5s in the car and/or through a computer the same thing as charging through an outlet?

No. The iPhone wall adapter supplies 1 amp. Most computers and built-in car usb ports only supply 1/2 amp. So it will take twice as long to charge using those. And, if the iPhone is actively being used (such as using it as a GPS in a car) it won't charge at all, because the battery will be draining as fast as it is charging.
You can get higher current adapters for cars (I just got an InCase 2.4 amp car adapter yesterday at an Apple store), and some newer computers can supply 1 amp (including all Macs since 2011). There is no iPhone benefit to an adapter that supplies more than 1 amp because the charging circuit in the phone limits the charge rate to 5 watts (1 amp @ 5 volts). An iPad, however, can use up to 2.1 amps (12 watts).
