Solved battery-lasts-half-an-hour prob

I've had a big problem with my ipod mini (4GB). Battery lasted only for half an hour, and sometimes, not even that long.
Tried everything (during the last few months), have read bunch of tips, hints, etc. and didn't solve the prob. Took it to an apple service (in Croatia) and they didn't want to even try to fix it.
Yesterday I've just dissasembled it. I reconnected the battery, blowed it a bit and cleaned the connector with fingers, and assembled it again. Also, I've installed the original firmware v1.0. And now battery lasts for 2 hours and counting... :))))))
DO THE DISSASEMBLY AT YOUR OWN RISK. FORGET THE WARRANTY IF YOU DECIDE TO DO SMTH LIKE THIS!!
Is it possible that cleaning the battery connector helped? Ipod was used on the beach all the summer (actually 2 summers) and one time it was a bit wet (with seawater, one bottun didn't work for one hour).

You can follow these steps to save battery.
1. Turn on Auto-Brightness - The iPhone has an ambient light sensor that adjusts the brightness of the screen based on the light around it (darker in dark places, brighter when there's more ambient light) to both save battery and make it easier to see. Turn Auto-Brightness on and you’ll save battery because your screen will need to use less power in dark places.
Find it in the Settings app -> Brightness & Wallpaper -> Auto-Brightness On
2. Reduce Screen Brightness -the brighter the default setting for the screen, the more battery it requires. Keep the screen dimmer to conserve more of your battery.
Find it in Settings -> Brightness & Wallpaper
3. Stop Motion (iOS 7) -It's really cool, but it also drains battery. You may want to leave it on to enjoy the effect, but if not, turn it off this way:
Settings -> General -> Accessibility -> Reduce Motion -> move slider to green/on
4. Turn Bluetooth Off- Turn off Bluetooth except when you’re using it to squeeze more juice from your battery.
Find it in Settings -> Bluetooth -> Move Slider to Off
5. Turn Off Location Services -
This allows your phone to know where you are and give you exact driving directions, give that information to apps that help you find restaurants, and more. But, like any service that sends data over a network, it needs battery power to work. If you’re not using Location Services, and don’t plan to right away, turn them off and save some power.
Find it in Settings -> Privacy -> Location Services -> Slide to Off
6. Don't Automatically Update Apps (iOS 7)-
If you've got iOS 7, you can forget needing to update your apps by hand. There's now a feature that automatically updates them for you when new versions are released. Convenient, but also a drain on your battery. To only update apps when you want to, and thus manage your battery better:
Settings -> iTunes & App Store -> Updates -> move slider to off/white
7. Auto-Lock Sooner -
You can set your iPhone to automatically go to sleep – a feature known as Auto-Lock - after a certain amount of time. The sooner it sleeps, the less power is used to run the screen or other services. Try setting Auto-Lock to 1 or 2 minutes.
Find it in Settings -> General -> Auto-Lock -> Tap your Preference
Few more things that would consume battery even when not is use are the applications that run in background.
Follow the below steps to quit all running applications.
1) Double tap on the home button on the iPhone ( this will display all apps that are running in the back ground).
2) Just click on the tiny red X to quit application ( if iPhone is running on iOS 6 and below) else just swipe yhour finger over the running app upwards to quit ( if running on iOS7).

I have an iPhone 4s just eight months, it is normal that the battery lasts only 3 hours? please help me thank you very much.

I have an iPhone 4s just eight months, it is normal that the battery lasts only 3 hours? please help me thank you very much.

Three hours if definitely NOT normal. I get at least 48 hours out my 2 year old iPhone 4S' battery with light usage. Did you do the iOS 7 update on the phone it self (OTA) or through iTunes? In my experience most problems are caused by the OTA updates. For this reason I ALWAYS update using iTunes on my computer.
I would suggest restoring your phone using iTunes on your computer and setting it us as a new phone. This downloads a fresh copy of iOS 7.1 from Apple and installs it on your phone. Just make sure that you transfer all purchased items (apps, music, etc.) as well as photos to your computer before restoring as the restore will completely wipe your phone. Do not restore from a back-up. Yes, you will loose all your data on the phone but restoring a back-up can restore the problem you are currently having back to your phone. Once your phone has been restored you can manually sync back your apps and music.
Before restoring you can also check to see that battery-killers like Location Services, Background App Refresh, etc are only turned on for the apps that really need it. I recently read and article that said that the Facebook app can be a real battery killer. If you have this app installed turn of location services and background app refresh for this app and see if that helps. Also go to Settings / General / Restrictions / Location Services / System Services and turn off all the options in that menu. Your phone does not need any of those to function. Constantly using your phone's GPS is a huge battery killer. I only have Location Services enabled for Find my iPhone and Background App Refresh is turned off completely.
I hope this helps.

I currently have an I5 and as with the previous I4, both buttons have failed and now my battery lasts almost six hours if I don't use it. I cannot upgrade my phone until March, 2015 even though I recently upgraded my phone to the More Everything Plan. Am I destined to be a nonuser for three months until I can upgrade. This is very unacceptable as I've been a Verizon Wireless customer for probably 20 yrs!

As a 20 year customer of ours, we certainly appreciate your loyalty Richey_Rich. I know the importance of ensuring you have a properly operating phone. Can you please clarify which button on the device is not working? Is there any physical or water damage to your phone? Any applications that stay running?
Thank You,

Updated ipad 2 now battery last about an hour?.

Can I download an older version of ios? this new one is a battery vampire. With no new apps and all apps closed in background ipad now barely last over an hour compared to 5-6 before. if you surf the web you can watch the battery drain around a percent per min. Anything i can do?

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. If the above test does, in fact, indicate a problem, read this.
Also, 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.

MBP 15'' 2011 battery lasts only 3 hours!

Hi
I bought MBP 2011 15 inch last week and received it on Monday.
My configs are
Model Name:          MacBook Pro
Model Identifier:          MacBookPro8,2
Processor Name:          Intel Core i7
Processor Speed:          2.2 GHz
Number of Processors:          1
Total Number of Cores:          4
L2 Cache (per Core):          256 KB
L3 Cache:          6 MB
Memory:          4 GB
and I also upgraded to high resolution.
So far, I'm pretty much enjoying my new MBP
But I have one main concern with my new laptop's battery time.
The battry time is really really short!
When I first turned it on, it took 3 hours to drain the battery. (starting from 98% or so)
And I did calibration thing so that the battery runs more "efficiently"
Of course, I didn't expect that calibration would make the battery last longer, but no matter what,
I only get 3 hours of battery life and I'm not even doing something that would drain my battery fast.
I just do simple web surfing and word documenting on about 30-40% brightness (or even lower sometimes)
And I get only 3 hours of bettery time.
So is this because my MBP has four i7 cores or or what?
Previous MBP 15'' models seem to last at least around 5 hrs doing exactly same thing.
And considering that I have been using my MBP only for 5 days or so, I'm worried that the battery life will become even less!
Maybe like 2 hrs?
Is this a particular issue with my laptop, that I can return and exchange to new model or get fixed without fees?
Or is it just built this way that all the MBP 2011 15'' models have this kind of short battery life?

OMG turning off the Bluetooth just gave me like extra 3 hours of battey time! (6 hrs total)
I didn't even know it was turned on in the first place because I never touched it.
I guess bluetooth is on as a default setting.
Thank you so much for advice.
I feel so stupid, but please be understanding since it's actually my first MacBook.
But I'm really glad to find out that I was wasting battery with bluetooth on, and now I can get better battery time.
Thanks once again!

2 year old iPhone 3GS battery lasts only 4 hours?

Hi,
My iPhone 3GS (bought in July 2010) battery lasts from 4-6 hours with light usage (no 3G, 5 mins of web browsing, 15 mins of music playback). It is definitely not an issue of iOS 5 as it was giving much better battery life even after the update. Tried restoring but no change. Also, sometimes it displays random battery charge percentages and shuts off on its own. When it is fully discharged, it takes 30 minutes minimum for the iphone to boot up even when connected to an iPad power adapter. Should I replace the battery?

Did you restore from backup or as new? If from backup, restore as new and see if the problem continues.
If it does, take the device to Apple for evaluation of the battery.

After Bell Update - My battery lasts only 8 hours

Hello
I have a Nokia N8. As there was Symbian Anna on it, I have optimized my battery consumption. It was running at least 2-3 days.
Now after upgrading to Anna it lasts only 8 hours. This is really not much.
What can I do? I have no Apps like Skype or WhatsApp running. Also I disabled all autostart apps with SafeManager.
Thank you

Hello
I think I found the solution.
I am patricipant of Nokia Beta Labs. So I have a lot of Beta Apps installed.
The last update for Store QML client (http://betalabs.nokia.com/apps/store-qml-client?req=true) helped a lot.
But the major Battery consumer was the new Nokia Maps Suite 2.0 (http://betalabs.nokia.com/apps/nokia-maps-suite?req=true).
If you have installed this, than you have to install Pulse as well!! (http://betalabs.nokia.com/apps/nokia-pulse).
In Pulse, there are two options, wich you have to disable both.
Then Symbian Belle goes even longer than Anna! =)
Here is some ohter discussion about the same topic: http://betalabs.nokia.com/apps/nokia-maps-suite/bugreport/43877/complete-battery-drain-overnight
This helped alot.
Thank you all.

Macbook pro mid 2011 battery lasting only 3 hours

How can I get my brand new Macbook pro mid 2011 battery to last longer, now it's lasting only 3 hours.

Do not believe the advertised specs from any manufacturer regarding battery life. In the real world expect about 60% to 70% of those figures. Battery life is influenced by many factors, Among these are display brightness, the number and type of applications you are running, if the optical drive is used, external devices that may be attached etc.
3 hours seems a bit low but not necessarily out of line. Go to SYSTEM PROFILER>POWER and see what it says by 'Condition'. If it is other than 'normal' you may have battery issues (Explanations then can be found in FINDER>HELP).
Ciao.

My iPhone 4 is only 14 months old over dropped very well looke after, one day the lock button stops then the volume buttons, now the headphone port does not work and the battery lasts about 4 hours after full charge I still have a year left on my contract

My phone is 2 months out of warranty, it's never been dropped or miss used yet the past week every day something has gone wrong with it. First the lock button stopped then the side volume buttons. Then the head phone port when I putt headphones in the phone turns the volume
Down automatically and it won't turn up until I take my headphones back out. The battery lasts 4 hours max after a full charge and today I took my phone off the docking charger and all my music has gone! The phone is breaking down more and more everyday what is going on! I know people who have had there iPhones years an non of this happen! I still have a year left on my contract too!

Who is your carrier and what is your coverage with them? If you are with say Verizon, and have Total Equipment Coverage or Extended Coverage, they will swap it out for you under Manufacturer Warrantee.

New battery lasts 1.5 hours...

I recently noticed the battery in my 7 month old MBP was not holding a charge for much more than an hour and a half. I took the machine into the Apple store where a Genius said he could find nothing wrong with the battery. He asked me to diminish the brightness of the screen, be mindful of running too many applications at one time and use wi-fi only when necessary. And he told me that the advertised 'up to five hours wireless productivity' for my machine was a 'perfect world' scenario, unlikely to be repeated in the real world. He said I should probably expect 2-3 hours of battery life on a full charge.
Within a few days I was back in the store complaining that after making those adjustments I was still getting the same battery performance...about an hour and a half of wireless internet off a fully charged battery. The same genius I saw previously handed me a new battery and said my problem should be resolved with the new battery.
I went home, calibrated the battery and charged it overnight. The next morning, I disconnected the power adaptor and the computer said the battery was fully charged and had an hour and a half of life...or almost 2 hours when I turned off the wi-fi. And that seems to be about what I am getting...an hour and a half of wireless internet or two hours of word processing. I think that seems really paltry and seem to remember getting about 3.5 hours of time playing a DVD when I first bought the machine.
Can anyone confirm for me whether or not I should be getting more than 1.5 hours of wireless internet or 2 hours of word processing (with wireless turned off)?
Thanks!
Here are the specs for the battery I am using now:
Charge Information:
Charge remaining (mAh): 5262
Fully charged: Yes
Charging: No
Full charge capacity (mAh): 5519
Health Information:
Cycle count: 3
Condition: Good
Battery Installed: Yes
Amperage (mA): -3094
Voltage (mV): 12009

Yes, you should be getting more battery life than that.
Check Applications > Utilities > Activity Monitor, set the popup to Show: Active Processes and click on CPU to sort. My guess is that there's a background process that's using a fair amount of CPU capacity, which definitely causes the battery to run down faster.
Failed print jobs, certain widgets, etc., are common culprits. If you find something, you can kill it with the Stop button.
Hope this helps...

MacBook Pro 13" Battery Lasts Only 2 Hours

I have Snow Leopard (10.6) installed. Why is this happening?

Hi LeonardoGolden,
You should definitely be getting more than 2 hours with that sort of Full Charge Capacity on your machine. I have the same model and a slightly lower battery capacity and I'm getting 4+ hours of web surfing and document composition.
Out of curiosity, how is the machine being used? It's obviously a pretty new unit (with only 3 cycles), if you go into Activity Monitor, change the drop down to "All Processes" is there anything consuming more than 10% CPU load? What applications are using during this two hour window?

Battery lasts only 4 hours

My I phone 3 helded a charge much longer. does anyone know why these don't. I shut the apps. any other suggestions?

The iPhone 3G battery loses around 20-30% of its original capacity after 300-400 charges/discharges. That means around 2 years of use.
If you charge your iPhone before being full discharged you're wasting a charge cycle, so you could lose 20-30% of its original capacity much sooner.
Apple offers a battery replacement program. You can find more information about it here: http://support.apple.com/kb/index?page=servicefaq&geo=United_States&product=ipho ne
Left side Menu > Battery Replacement.

My battery lasts only 3 hours or 4 with the new OSx Lion instead of the 6 to 9 that lasted with Snow Leopard

Anybody has the same problem?

Yes, same problem. There are a lot of people having the same issue, as noted in this thread: https://discussions.apple.com/thread/3194235
Resetting the SMC has done nothing. I'm on a 2011 15 inch MacBook Pro running 10.7.1.
This is not good.

How long does the macbook pro 13 retina battery last

I just recently got my macbook and was wondering this because i am a bit scared. Apple says their battery lasts around 9 hours, what does that mean? If just doing simple work like pages and other programs a like, my battery will last up to 9 or 10 hours but that is when my brightness is less than 60%, it lasts maybe 8 hours at full. However, when I'm doing searches on safari like going on websites and youtube, my battery only lasts about 6.5 hours at 40% brightness, for some reason if i am on netflix it will last longer, maybe for about 7.5 hours 40% brightness. I personally would be happy with 6+ hours and keeping it at a low brightness but if I'm supposed to get more battery than why not?! P.S. When i go on activity monitor it says that none of the applications are using more than 5% (except activity monitor).

Hey samraymond,
Welcome to the Apple family, I’m glad to hear that you have purchased a new MacBook Pro with Retina Display. Our marketing pages state that the 13-inch MacBook Pro with Retina Display can last up to 9 hours. However, please keep in mind that battery life will definitely vary by use and configuration. Our technical specifications page provides more information on the testing that was conducted to determine battery life:
Apple - MacBook Pro with Retina display - Technical Specifications
http://www.apple.com/macbook-pro/specs-retina/
Testing conducted by Apple in July 2014 using preproduction 2.5GHz quad-core Intel Core i7–based 15-inch MacBook Pro units, preproduction 2.2GHz quad-core Intel Core i7–based 15-inch MacBook Pro units, and preproduction 2.8GHz dual-core Intel Core i5–based 13-inch MacBook Pro units. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%. The HD movie playback test measures battery life by playing back HD 720p content with display brightness set to 12 clicks from bottom or 75%. The standby test measures battery life by allowing a system, connected to a wireless network and signed in to an iCloud account, to enter standby mode with Safari and Mail applications launched and all system settings left at default. Battery life varies by use and configuration. See www.apple.com/batteries for more information.
