IPhone 5 short battery life?

I was lucky and got my new phone yesterday, but the battery barely lasts. After checking my email for about 30 seconds i lose 2%. I made sure nothing was running in the background, but the drain is worse than my 3GS I just upgraded from. Any suggestions?

Hi from Vancouver. Just thought I'd add my voice to the mix. Yes same exact thing happening with mine as well. It was in standby for about 3 or 4 hrs and dropped from 100% to 77%. It was almost completely dead after 6 hours of using it lightly yesterday as well. Tried a hard restart a few times too with no luck. Hopefully we'll figure it out! There must be something going on.

Has anyone encountered drastic shorter battery life both on iphone 5 and ipad since updating to iOS 6.1.2? How can this problem be solved?

Dear all,
I am new to this community even though I have been a Apple user for years, so please forgive me if this question is not in the right section.
Has anyone encountered drastic shorter battery life both on iphone 5 and ipad since updating to iOS 6.1.2? I've always been happy with these two products until the update - now the battery life is considerably shorter which is extremely frustrating.
How can this problem be solved? Is there any way to go back to the previous version?
Thanks for your help.

If you update using iTunes the phone is first wiped clean, then the new OS is installed, and finally the backup is restored. After this finishes if you sync your music should be restored. Music is not in the backup, because it is already on your computer and duplicating it would use up a lot of hard disk space.
An OTA update just patches what has changed; it does not disturb content.

Iphone 5 VERY short battery life since 6.0.2 update.. Is there anything to change that? :/

Very short battery life on my iPhone 5 since 6.0.2 update. I got up this morning and it was only half an hour in use and it already lost 10% of battery life! Please fix that apple!

Apple is still signing for 6.0.1 so you can RESTORE BACK to 6.0.1. Just download the 6.0.1 IPSW for your device and then press the shift key while pressing restore (on windows) which will open a window. Select the downloaded IPSW and you'll be back on 6.0.1. And since Apple is still signing 6.0.1 THIS IS NOT A HACK
OR AN UNAUTHORIZED downgrade. So it DOES NOT void your warranty because Apple is allowing you to downgrade because they've allowed the 6.0.1 window to remain open. I did it for a friend's iPhone and it all worked out fine.

Possible work-around for v3.0 short battery life

First: be aware there's a difference between "Push" (which is for some email account types & some MobileMe features) and "Push Notifications" (which is for apps). They are controlled in separate Settings screens.
Short story:
If you've upgraded to v3.0, usually have Wifi ON, and experiencing short battery life, and if you can live without Push Notifications (at least until Apple finds a better solution), TRY TURNING "Push Notifications" OFF.
Alternatively, if you can live without Wifi but need Push Notifications, try turning Wifi off & let the data travel via 3G.
Long story:
First I ran alternate days with Wifi ON, then Wifi OFF, and noticed with Wifi OFF my battery life was nowhere near as short (I could get through a day), but with Wifi ON, I can barely get through half a day. This is very different to v2.21, and in my setup the only significant difference was Push Notifications being ON.
Then today I've been running continuous pings from my Mac to my iPhone, with various combinations of Push on/off, Push Notifications on/off, email accounts on push / fetch / manual, and discovered there's a huge difference in how often Wifi gets turned on when Push Notifications is enabled.
With Push Notifications ON, while your iPhone 3G (and probably 3GS) is asleep, Wifi will be turned on for 15-20seconds every 1 to 2 minutes!
This is in stark contrast to Push Notifications OFF, but Push (for email, MobileMe, etc) ON, where Wifi is on only as often as your email account settings dictate.
This explains a lot, I think. With Wifi OFF, data goes through the 2G/3G radio, which is inherently ON all the time (for phone functionality), so the incremental 'cost' (to battery life) of Push Notifications is comparatively small.
But with Wifi enabled, data is instead sent via Wifi. The incremental cost (to battery life) is dramatically higher having to turn on the Wifi radio, find the WLAN, get an IP from DHCP, then exchange data with various Internet servers, when it happens every couple of minutes!
Though I'm not really sure what Apple can do about this situation. They appear to be turning Wifi on frequently to give the illusion of true (ie timely) push notifications. I think this situation runs parallel to those who found, with v2.x, that enabling Push on email accounts & Wifi enabled had similar major negative impact on battery life. Except now heaps more people want the Push Notification feature. Interesting conundrum...

The main thing that helped me with the short battery life was lowering the brightness. My 3G was so bright I could'nt sleep at night.

Short Battery Life and Very Slow Data on 4S

Short Battery Life and Very Slow Data on 4S,
anyone else noticing the slow speed of data on this phone?

Yes, I measure my slow data on Sprint in kpbs, not Mpbs. Like standard is download maybe 250kpbs, upload 100kpbs (that's 0.25 Mbps and 0.1 Mbps). On the same tower my buddy who has an AT&T iPhone 4 shows 2.5Mbps download and 1.5Mbps upload (that's 2500kbps and 1500kpbs), a LOT faster. Sprint has not been much help.

IPhone 6 battery life draining since 8.1 update

Is anyone else having problems with their iPhone 6 battery life diminishing since the latest 8.1 update? I notice I'm getting much less usage time per hour. For example, before 8.1, it would take about 3 hours of usage time to get to 70%. Now it only takes 2 and it gets worse after that. Here is a screenshot I took of the battery usage before the 8.1 update:
This is pretty normal usage timings for me (it was taken Monday, October 20th). Now, here is a screenshot from today, after starting out with 100% this morning:
As you can see, it's quite a huge difference. The weird thing is that messaging seems to take up more battery life than it used to. Yes, I do text quite a bit during the day but the frequency of this has not changed between now and October 20th. It shouldn't be using THAT much battery life. I took it to the Genius Bar yesterday to ask them about this problem and the girl told me that she saw some crashing from the Messages app in Diagnostics Information and she felt that maybe since the update, there was something causing that app to use more battery. So she suggested erasing the phone and restoring from an iCloud backup. I did this yesterday when I got home but, as you can see, the problem is no better (though there are no more crashes listed in the diagnostics information).
I have no idea what else I can do to fix this and I'm getting really tired of having to charge this twice a day now (I used to have to do this with my iPhone 5, as well). If anyone has had a similar problem, I would appreciate suggestions. And before you ask, I'm doing all of the normal battery saving tricks, like turning off background app refresh, not having it check for mail all the time (it's manual), brightness is down, I turn wifi off when not using it, I don't leave apps open, etc etc etc.
Any help would be appreciated. Thanks in advance!!!

I turn off background refresh, mail push/fetch, and I turn off wifi and bluetooth if I'm not using them. I also minimize which apps use location services. Even when doing all of that though, the battery life became terrible on 8.1. Since updating to 8.1.1 all issues seem to have been fixed so I'm very grateful for that. I recommend anyone on 8.1 who is having issues to upgrade to 8.1.1 immediately.

When I got a new iPhone5, I experienced short battery life, and system sofware issues were not the cause. The camera also takes a blury picture regardless of lighting and I have the black one. Has anyone else experienced similar problems?

What makes you so sure it isn't software?
The camera can be focused by take the point of focus on the touch screen.
If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

My MacBook Pro is really hot and the fan is on constantly. It didn't use to do this, does anyone know why this is happening? I have a very short battery life, so I have to keep it plugged in probably more than I should.

Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

Want to increase iPhone parts battery life

Hi..Friends i want to increase my iphone parts battery life ..Please share some tips with me...

Hmm.....
the phone is solid state.... there's hardly any parts to wear out.
I guess you avoid pressing the home button? Carry a bluetooth keyboard?
the old phone connector can wear out, but I hear the lightning connector is improved. You do need to charge the phone regularly and you need to have it disconnected when the phone is away from the charger
avoid water or moisture. Potentially a problem in humid climates and having the phone in your pocket
avoid drops or impact that can crack the screen or dent the case?
perhaps a "bumper" or case to keep away scratches?

The cause of the whine, heating and short battery life.

It seems like we've discovered how we could fix the whine, heating and the short battery life.
If you take a look at /var/log/System.log
You will find this line:
localhost configd[37]: com.apple.SystemConfiguration.DynamicPowerStep load failed
Yes, that's right. Intel SpeedStep is not implemented in Mac OS X.
It seems like Apple wanted to implement it, either the engineer in charge of it was screwed up or apple was hurrying to get macbook pro released...
This also explains why Macbook pro has a higher battery life, runs cooler without whine on a properly configured Windows XP (with updated intel drivers and microsoft hotfix). On Windows XP, when the system is Idle, CPU is throttled to 1GHz.
So we have two options:
1. Get Apple to implement it correctly - but so far it doesnt seem like apple is really concerned about this issue. Or rather, they don't seem to care.
2. Implement it ourselves - A guy called Cryptonome was trying to implement the proper power management for MacBook Pros on Mac OS X to solve these "CPU whine", heating and battery life problems, and he did have some fruitful results, but it seems like he's currently too busy or something to finish the implementation.
Unfortunately I am not a genius so I cannot implement anything like this... anyone?
What do you guys think?

That's exactly what I am doing : expecting a solution from Apple. And you know what, Apple today released a new system update for the keyboard. This update is for all the MacTels including MacBook Pro. And guess the next thing... This update fix a power draw in the MacBook USB... Great... Oh, no, in fact not so great because this bug is THE bug that allows to stop the whine (through Mirror, etc)...
Is there anyone in Apple that tests fixes before to release them ? Do those engineers working on the whine fix have given a look to that patch ? I really hope that Apple is doing something, but releasing this Keyboard patch for MBP now can mean 3 things (IMHO) :
- the whine patch is on the final steps and will be released soon, so killing the workarounds for the whine is not a problem,
- or Apple has a partial (or even none) knowledge about this problem, and they should hire better engineers, because many people made a lot of discovers about this whine, not beeing engineers,
- or Apple definitly doesn't care about this whine problem, and they will loose myself as a customer (and probably others).

Does anyone know what's up with the iPhone 4s' battery life? Some days it last a long time and other days it drains extremely fast.

Does anyone know what's up with the iPhone 4s' battery life? Some days it last a long time and other days it drains extremely fast.

Not to point out the obvious, but battery life depends very much on what is running and how much the device is being used.
If the battery lasts longer on a day you make no phone calls, but lasts less the day you make 5 hour long calls, this is to be expected.
If however the iPhone has the same level of use on both days, with different power consumption, this would infer a background process (or App) is trying to do something (connecting to server or creating a back up etc).
I switched off all thrid party apps from being included in my iCloud backup, which saves a huge amount of space on the cloud and allows the back up to take barely a couple of minutes.
Battery life seems ok so far on my 64GB 4S (Bluetooth on, Wi-Fi on, Location Services on, Push notifications on, Screen set to just under half brightness with Auto Adjust on)

Hot battery and short battery life after download of Mountain Lion.

Hot battery and short battery life after download of Mountain Lion. Any suggestions?

As in, shortly after install?
Note after you install Mountain Lion it's likely that the Spotlight index will be rebuilt. This will take some time and the machine will run hot. After this completes, which could take 1-2 hours, things should return more to normal.
If they don't, I suggest running Activity Monitor and seeing if you can trace what is eating up CPU cycles.
