100% to 20% battery life in 3 hours iPod 5

I have iOS 7.0.3 and my iPod 5 battery life is draining really fast. It used to go from 100% to 20% in 10+ hours but now it does that in 3 hours!!! I've done all the "switch off this and that" and all that stuff. My brightness is on 0% for goodness sake!!!!!!! Why is it like this!?

Using the battery level meter in this manner is comparable to using your car's fuel gauge to calculate miles per gallon. The only thing that matters is the total amount of operating time from full charge to auto-shutdown.
Use the wall-mount charger that came with the iPad and charge overnight. Do NOT use an iPod/iPhone charger. Do NOT use a computer's USB port. Then, operate it normally until auto shut-down (ignore any low level alerts that may appear). An irony is that doing that test to determine the total operating time is also the procedure necessary to calibrate the battery level meter.
I'm not claiming that you do not have a problem. I am stating, however, that we don't yet know.
According to Apple:
Use Your iPad Regularly
For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
Elsewhere, Apple elaborates and explains that two half-discharges (or four quarter-discharges, etc.) equals one full discharge.

When you "Restore from a Time Machine Backup.", the drive will be erased for you, but yes, won't hurt to:
Boot into Recovery (hold ⌘R on boot)

Battery life, only 3 hours?

Hello everyone I come to you tonight with a question regarding my Macbook Pro's battery life.
This computer is fairly new, it was purchased in September of 2011. At the time I was getting the advertised 6-7 hour battery life.
As time goes on, I do understand that the battery, will wind down. As of right now, I'm at 147 battery cycles and my batters "hp" (whatever that means, I don't know how that's measured.) is at 95%.
So with that, I'm now only getting 3-3.5 hours of total battery life, with my bluetooth off, and I'm only doing minor web browsing, with no flash. I'm writing this, with the only other application open being iTunes, and my timer is at 3:35 minutes @ 97% battery. My keyboard backlight is off, and my screen is only on 3 dots of the total possible. (Sorry that's very poorly described, I'm not sure of the proper way to go about it.)
So I'm wondering, is there anything that I could or should do to fix this?
The specifications for my computer are as follows, for those interested.
Mac OSX 1.7.2
2.7 Ghz Intel Core i7
8 gigabytes of ram
Thank you.

Does anyone know the battery life (how many hours)of new ipod nano 7th gen while using bluetooth?

Hoping to find out the battery life of the new nano (7th generation) while using bluetooth. Has anyone found out how many hours the new one gets with BT?
I have the 6th generation nano, and while using bluetooth it only makes about 3 hours before being fully drained.

About 9 hours continuous runtime with BT + music playback in this review at least - http://www.ilounge.com/index.php/reviews/entry/apple-ipod-nano-seventh-generatio n/P5

W520 - Battery Life Under 2 Hours!

Hello there!
I've been experiencing the problem where my Nvidia Graphics card does not automatically switch to the Intel Graphics card --- or if it does --- it does not allow me to have the 5 hours + of battery life that I use to have when I was using Windows 7 (right now I am using Windows 8).
I also don't have the Lenovo Power Manager program installed because I can't seem to find it anywhere on the installation pages for my particular laptop with Windows 8. I wonder if this is the problem since its using Windows Power Manager -- even though I have installed the Power Driver multiple times.
Even when I get it so I make sure that no applications are using the Nvidia Graphics card (confirmed by the Nvidia GPU Activity icon), I still get the under 2 hours battery life. I am using the 9v battery -- the larger one.
Any help would be greatly appriciated so I can get the full battery life out of this laptop, as when I had Windows 7 installed. Thank you :-)

Hi brooklotzkar
1. Go to Control Panel (Small icons)> Lenovo - Update and Drivers > Install all critical and recommended updates. Optional - Up to you to decide as you may not be using all the functions. If this options is not available, Download here and install.
2. Go to Control Panel > Power Options > Check Power saver. Power Plan make a big difference on both battery life and performance.
From what I tested on my W520 - Core i7 2720QM
Maximum Battery Life or Power saver: CPU clock speed at 800MHz constantly, but performance decrease. You wouldn't want to multitask too much when on battery.
Maximum Performance or High Performance: CPU clock speed will go up from 3 - 3.2GHz (Depending on how many core / thread the program will utilize)
3. Battery will vary depend on how many / what kind of apps are opened. I have tried using 5+h on 6-cell battery without any problem. (Battery Stretch, only running Microsoft Word and 1 tab of Internet Explorer) It is recommended to run Internet Explorer on battery as it requires less resource, hence battery life will not run out as fast.

Horrible battery life with brand new iPod touch 2G

There is definitely something going on with the battery life on my 2G. I just got a 32GB iPod touch 2G on Wednesday to replace my 32GB iPod touch 1G and the battery life is atrocious.
I charged it up fully and Fetch/Location Services is disabled. Backlight was set to auto and WiFi was on. I browsed the net for about an hour (no music playing), watched a 6-minute YouTube video, and played five minutes of X-Plane.
The 20% battery message came up after about an hour and a half of total on time from a fully charged battery. My 1G would have been above 70% at that point.
Then last night with a fully charged battery, I read a few posts on Apple Insider, played some Solitaire, then put the device to sleep, and awoke this morning to find the battery at 20% with a warning message. I always have WiFi on.
Now I am using my 2G no different than my old 1G -- I have the exact same usage patterns including WiFi usage, yet battery life is much, MUCH worse. What's going on?

Fully charge the iPod a few times, then use it until it goes out of battery. Do this 7-8 times, then check the battery life again - new batteries do this often in the beginning.

Is the battery life in my 4G iPod touch depreciating?

I have a question regarding my 4th gen iPod touch. I bought it on Sept. 22, 2012, so it's about 3/4 of a year old. I usually browse the web, watch YouTube videos, play graphics-intensive games like Infinity Blade and GTA Vice City, and I often have it in my dock so I could listen to music. I had it in the dock pretty much all day over the last four days listening to music, and I took it out a few times each day to check Facebook and engage in some hardcore gaming sessions. (I use my iPod touch like how a PSP or PS Vita would be used.) While writing this question, I had the screen at minimum brightness (I'm in bed) and the battery has gone down about 7% since starting this question.
I do follow the full cycle charge, however I often end up doing it more like 6 times a month insted of once.
Is this okay or is my iPod touch's battery life starting to become horrible?

And I thought that shallow charging cycles were bad for the battery. (I heard that keeping the battery constantly at 90-100% is bad for it.)
Nope, not the case at all with Lithium batteries. Frequent partial dischage and charge cycles will not harm them, nor will leaving it fully charged and using it plugged in (it has built in overcharge protection circuitry).
As lllaass mentions, it is the older technologies that had issues with recharge memory effects and so forth - NiCAD and NiMH batteries - but Apple dropped those technologies over a decade ago.

Battery life about 2 hours from a full charge

I ran an EtreCheck and see a lot of problems but am not sure how to deal with them. Any help would be appreciated!

future battery considerations:
Gaming: In cases of heavy and frequent use in gaming it is recommended, if possible, to keep your Mac plugged in since these frequent fast and deep discharges of the battery are not ideal for battery longevity.
If you were to always keep your macbook battery floating between 20% and 80% charge roughly, then you’d have no other considerations to make about your battery and its care,… except for long-term storage.
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*Contrary to some myths out there, there is protection circuitry in your Macbook and therefore you cannot overcharge it when plugged in and already fully charged
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity. Same way you don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

Battery life 5-6 hours?

So I called apple because I have only been getting about 2 hours running Garage band and text edit with Bluetooth and airport turned off and the screen on next to last darkness. They told me that they are only replacing the batteries that get 30 minutes of life when the computer is on. I asked what the settings are that get the claimed 6 hours, and she told me that this was in sleep mode. ARE YOU SERIOUS. how can you claim a computer gets bettery time when the computer is not even in use during that time. I could understand if it was not running anything and they just let it sit there with the screen as low as it could go, but sleep mode? is this really true?

Sleep mode will last substantially longer than 6 hours. At least several days.
Did the support person run you through:
calibrating the battery?
http://docs.info.apple.com/article.html?artnum=86284
resetting PMU?
http://docs.info.apple.com/article.html?artnum=303319
The 5-6 hours they claim is based on an unrealistic test scenario - much like EPA gas mileage ratings. How long does the battery last when you're not using Garageband, but just doing regular, everyday things like browsing with Safari, email, iTunes, etc?

IPhone iPod randomly shuts off, battery life is 2 hours

I really think there is something wrong with my iPhone because yesterday it was only at 2 hours of use time and 3 hours of standby time since full charge before it dropped to 20. I did use youtube and barely listened to music. Is that pretty normal?
Right now its only at 9 hours of use time and 10 hours of standby and its already drained down to 20%. I only listened to music with only 2 videos of youtube and about a quarter use of web browsing. I find myself having to charge it every night. Which means I cannot sleep with my iPhone while listening to music, or if I do that then it will be dead by the next day.
Then last but not least is at random times during web browsing, I haven't have proof to confirm that it does things outside of web browsing itself, the iPod music I'm listening to just stops. I double click the home button and it only brings me up to favorites.

I have the same iPod stopping during surfing... Your not alone.

MBA 11" battery life only 2 hours out of the box.

Should I have it replaced under warranty?

Out of the box... did you actually fully charge it? I somehow doubt it. Laptops are shipped with partially charged batteries to ensure they work. Read the instructions and let it charge for the appropriate time and try again. If it still does not work... take it back.

Limited battery life for 6th generation IPOD

H, a novice here! 6th generation IPOD, I only use Bluetooth wireless headphones. IPod will only hold charge for a little over an hour even when fully charged. Any suggestions welcome! Thanks

Sounds good. I'll keep an eye on this thread and watch for updates.
i have always used the Bluetooth because of its convenience
Most definitely.

I have no itunes app or safari browser also very poor battery life compared to my ipod touch 4. my phone is a virgin mobile usa iphone 4 i purchased 2 days ago ...stumped. i have not activated service on the phone because of this.or is that the problem?

a

The itunes app and safari app cannot be deleted. The came with the phone and are native to it. The must be on antoher screen or in a folder on one of the screens. Swipe across the screen from right to left to reveal other screen and look for them. IF you can't find them go to settings>general>reset then reset home screen layout. If you want to move apps touch your finger on the icon and hold it there until the icons wiggle and then drag the icons to where you want them then let go. Tap home screen once to make them stop wiggling

I want to save battery life on the new iPod touch 5th Generation, but I cannot find any solutions on the web? Has anyone got any solutions that I could use to extend the battery life?

If you have any solutions, please leave some under this discussion.
Thank you :-)

I'd say this article does a good job with that.

Ipad 2 battery life drain 10% by hour after 5.1

Hello, my name is Martin Vila.
I posted about this same issue a few weeks ago hopping that apple will give an update about 5.1 IOS for Ipad 2 but becouse I need my Ipad for dental school almost everyday i went and search a solution for my poor battery life. After upgrading to 5.1 my Ipad is almost useless with a battery life of 3 hours only with WIFI (this only happen hours after I update to 5.1) So i been searching on the web and I have found a few posts about this, but they are not confirm if this is an 100% solution, they say if i restored my Ipad from scratch using Itunes player my IOS will redownload and the battery will be ok ones again, so is this true, has anybody had this same problem before and had try this solution?, also if I restored my Ipad and I backup with Icloud my Ipad will be with the same apps and contents? I only care for "The skeleton system pro" app because I have a lot of notes in there.
PS: Sorry for my bad grammar, but english is my second language, greetings from Peru

Suggest you recalibrate the battery. See link below.
The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute.
