Manually stop battery charging to prolong battery life

I have a HP Pavilion G6 2320tx laptop with Win 8 preinstalled. I would like to manully stop charging the battery at - say 50% so I can increase its life. Is there a way to do this? I have tried disabling Microsoft ACPI-compliant control method battery but the charging light still stays ON.
Please help!!

Hi,
Keeping battery at 50% that means more charge cycles and this would destroy battery quicker. Please read the followinf articles:

I have a MacBook Pro 13inch 2.4GHz (Intel Core 2 Duo, 4Gb RAM, 250Gb HDD, NVIDIA GeForce 320M graphics, SD card slot, up to 10 hour battery life)bought in October 2010 in the UK. The charger has stopped working. Which model and voltage do I need please?

I have a MacBook Pro 13inch 2.4GHz (Intel Core 2 Duo, 4Gb RAM, 250Gb HDD, NVIDIA GeForce 320M graphics, SD card slot, up to 10 hour battery life) bought in October 2010. The charger has been playing up for a while now - the light going out but coming back on when I move the cable a bit - faulty connection it seems. It has now stopped working at all.
Apple UK charge a whopping £65 for a replacement - and the reviews are AWFUL for it!
I need to know which one I need - 45w, 60w and 80w are listed - can someone tell me please? If I'm going to pay this price I want to make sure I get the right one!
Also, is a genuine Apple one available on Amazon UK, does anyone know please?
Any help will be much appreciated.
Meanwhile my battery is going down.....

Thanks for that wjosten. Much appreciated.
I've read here on Apple's site that the 85W version will work, as you say, and that it would run cooler with a 13" Macbook - I have a 13" MBP of course but assume this would be the same with mine. I wonder if running cooler is a good thing (it sounds as if it is) and it would be better for me to get the 85W version than the 60W one?
Then I have to decide whether to pay the (extortionate as it seems to me, though I may be wrong) £65 from Apple (bearing in mind the rotten reviews here of the Apple product), or risk a cheaper alternative from Amazon UK, at around £20 (also with various rotten reviews)... Any suggestions? Please? :-)

At what percentage should I to charge my macbook pro and prolong the life of my battery?

I want to prolong the life of my laptop battery. I just got a new macbook pro and want to know the proper way to charge the battery.

The first days: leave it on the charger, until it says 100% for a few days.
Then from time to time use it without the charger connected. Let it loose charge until about 50-60% full, then reconnect the charger. You have to keep the "electrons flowing". In the past they said to "calibrate" the battery, but that just calibrates the electronics, not the battery, and you don't do that anymore.

Hello! I'd like to know about the battery. Can it lose the capacity? What can i do to prolong it life time? Full charge? How to proceed ? Thanks.

What is the Best Usage to Prolong MBA Battery Life?

Hello,
I have a new (1/27/2011) MacBook Air 13" (4G, 256G, 2.13Ghz CPU).
This is being written: 4/29/2011. For some time my charge indicator has not gone above 99% except very occasionally, and then, very briefly. I have noted an apparent decrease in battery 'life' (how long I can run the laptop from full charge to full discharge). Although I usually have only a browser (multiple tabs), WiFi (no Bluetooth) and, sometimes, a word processing application open with brightness at about 60%, but I don't usually get, lately, more than 5 hours max. For example I have running since fully charged (99%) for 2:40 min with the usage pattern described above, and I now have 39% power showing.
My normal usage pattern is to charge the battery fully and then let it discharge completely. If possible, I let it rest for at least a couple of hours fully charged on the charger, and fully discharged off the charger. This is not always possible but I probably do it 40 percent of the time, at least.
"About this Mac" (More Info) shows 66 cycles and Full Charge capacity as 6354 mAh and a capacity of 94%. CocoBattery 2.7 shows 66 cycle and 6352mAh, and age of the Mac as 19 weeks.
I feel that this decrease in ability to hold a charge is excessive compared to what Apple indicates is normal (80% loss in 2 years or 300 cycles). At this rate I will be at 80% of original capacity in 9 months, and 80% of capacity in about 200 cycles.
I have read several of the excellent posts on this forum as well as the Apple info on batteries, battery cycles, and laptop batteries referenced here, but still am confused as the best way to proceed in order to prolong battery life.
Would changing my usage pattern extend the working life of my MBA? Specifically (but not exclusively), would I be better off running on the charger more often, even if I were unable to fully charge or discharge the battery each time? As I understand it doing this will decrease my cycle count per unit of time, but it will also mean that I more frequently begin charging (or discharging) before current capacity (no pun intended) has reached maximum (or minimum).
If the battery were more easily replaced, I would be less concerned (though not happy ) for, otherwise, I am truly pleased with this elegant and generally capable computer.
Any information anyone can provide would be very much appreciated.
Pete

hi,
so what would you suggest to do here then. let it get to 50% then run the battery down and at say 5-%ish re-charge it fully.
is there anything i could switch off on my phone to save battery power. ive taken off he location services apart from ym locate my iphone, stopped the fetch new data and set it to manaul . this is also the same for the icloud as well.more or less everything has been set to manual or set to off ??

HT1414 IT SEEMS LIKE EVER SINCE I UPDATED MY 4s TO THE OS 6 MY BATTERY LIFE HAS BEEN CUT WAY DOWN!!! I NEVER HAD TO CHARGE THE BATTERY THROUGHOUT THE DAY LIKE I AM NOW WITH THE OS6 UPDATE

IT SEEMS LIKE EVER SINCE I UPDATED MY 4S TO IOS 6 MY BATTERY LIFE IS NOT WHAT IT WAS BEFORE DURING THE DAY. I HAE TO PLACE IT ON THE CHARGER MANY TIMES THROUGHOUT THE DAY

Please stop shouting at us.
All caps indicates shouting, is considered rude, and is difficult to read.
Many will not read such posts.
Have you tried the bascis from the manual?
restart, reset, restore.
Have you checked your settings to make sure that you do not have something running that you do not want to run?

Save and Protect your iPad Device: How to Save and Prolong the battery life of your new ipad

Please, as you read add more answers to this on how to prolong and save your ipad battery life. Thank you
Saving the battery life of your iPad
1.Keep Your iDevice Out of the Sun
Whatever you do, don’t leave your iPhone or iPod sitting in a hot car—heat kills batteries faster than any other factor, and your device that used to keep a charge for hours will eventually barely hold a charge, and you’ll have to pay Apple to get it replaced. The same thing holds true for any really hot environment: try and store your device in a cool place.
Reduce the Screen Brightness
If you keep the screen at maximum brightness all the time, you’re wasting a lot of battery life—and the screens these days are so bright anyway that you don’t really need to, especially at night. Head into Settings -> Brightness & Wallpaper to adjust the default level of brightness, which you can probably keep as low as 30% most of the time.
2. Make Sure the Screen Locks Quickly
Even if you’ve adjusted the screen brightness, there’s still no substitute for having it turn off quickly when you’re not using it. Head into General -> Auto-Lock to set the screen lock to happen as quickly as your device will let you. This makes a big difference if you are always picking up your phone and putting it back into your pocket without turning the display off.
3. Use Airplane Mode When You Don’t Need Internet (iPad/iPhone)
If you’re busy spending the next 8 hours playing Angry Birds, there might not be a good reason to have internet access, so you can consider using Airplane Mode, which turns off both Wi-Fi and the regular wireless radio. Of course, this will prevent phone calls if you’re on an iPhone—but if you’re busy with Angry Birds you probably don’t want the interruption anyway.
4. The more important reason to use Airplane Mode is when you’re mobile in an area with a really spotty connection—because the iPhone or iPad will try to stay connected at all times, it’s going to be constantly searching for a connection, which can drain your battery. Head into Settings and flip the Airplane Mode switch right up at the top of the screen.
Use Wi-Fi Instead of 3G if Possible
According to Apple, the iPad will get 10 hours of battery life under regular use with Wi-Fi enabled, but will only get 9 hours using 3G—the iPhone gets 6 for 3G and 10 for Wi-Fi. Of course, if you’re heavily using the Wi-Fi, you’ll still be draining the battery—the point is under similar workloads, Wi-Fi is better than 3G for battery life.
You can enable Wi-Fi under Settings -> Wi-Fi, and then pick the network you’d like to connect to.
5. Reduce or Eliminate Mail & Calendar Checking
If you’ve got a bunch of email, calendar, or contact accounts configured, and they are all being checked and downloading email on a regular basis, you’ll be draining the battery an awful lot faster than you need to.
Head into Settings -> Mail, Contacts, Calendars -> Fetch New Data and change the setting to the least frequent check possible. If you don’t use it often, you can just turn Push off entirely and then manually check when you need to.
6. Reduce or Eliminate Push Notifications
Do you really need notifications from Twitter or whatever other apps you’re running? You can turn these off one-by-one, or turn off Push entirely by heading into Settings -> Notifications, and save a bit of extra battery life since your device won’t be pulling in data for those applications anymore.
7. Reduce or Eliminate System Sounds
This one is probably a little silly, but if you really don’t care for the system sounds you can save a small amount of battery life by removing the sounds. A very, very small amount, most likely. Head into Settings -> General -> Sounds to change them.
8. Disable Location Services
If you don’t really need the location services, you can disable them to save some battery life. Head into Settings -> General and flip the Location Services setting to off.
9. Disable Bluetooth If You Don’t Need It
If you don’t use a Bluetooth headset or keyboard, you should keep the Bluetooth radio disabled to save some extra battery life. Head into Settings -> General -> Bluetooth to flip it on or off.
10. Disable Vibrate Feature in Games
If you’ve got a game that uses the vibrate feature, you can turn that off to save some battery life. This mostly matters if the game heavily uses it, and you’ll need to change the setting for the game. As a side note, and it should go without saying, if you’re running really intensive video games, they will kill your battery very quickly.
11. Charge and Discharge Your Battery Regularly
Your iDevice needs to be fully discharged and recharged at least once a month to operate at maximum efficiency and keep the battery from dying. You’ll also want to make sure that you don’t store the device with a dead battery, as that can also cause the battery to lose charge capability—when your battery dies, make sure to recharge it quickly.

Irem Bright writes and would love your own addition if you got other helpful tips.
Thank you all.

The reason that Apple suggests you drain and recharge your battery once a month is not because it affects the life ofthe battery. What it actually does is calibrate the battery sensor, giving you a more accurate reading.
Other than that, you done an admirable job of summarizing the Knowledge Base article:

Question about full cycle charges and battery life

So I've had the new iPad since day 1 and absolutely love it, though recently I've noticed that my battery life doesn't seem to hold up as well as it has in the past. I've done three full cycle charges since getting it however during my latest one I accidently brought along my iPod wall charger and not the one that comes with the iPad. My iPad was fully discharged and I plugged it in assuming that in the 7 hour window I had that it would be fully charged within 5 hours, but this was not the case due to me having the wrong charger. After about 7 hrs of charging it was only at around 60-70% so I had to unplug it, bring it home, then plug it in once more using the correct charger. Probably a fairly obvious question but does this not count as a full cycle charge because I unplugged it? Should I perform another full cycle charge even though this most recent one was not even a week ago. I know you're supposed to completely discharge your battery as few times as possible so it worries me having to do it again so soon.
About battery life, I've noticed lately that my iPad battery seems to be depleting quicker than normal, and was hoping that perhaps this was caused by being overdue for a full-cycle charge which I may have flubbed as seen above. I'm aware of a majority of the little tips and tricks to prolong battery life however I'm not so knowledgeable on the "do's and don'ts" of charging the actual iPad so any information on that would be helpful. I should also note that unfortunately I accidently left by iPad in a hot car for a little over an hour and was tremendously devastated knowing what this can do to the battery, so could this be the main cause for a seemingly weaker battery?
Thanks for any feedback!

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. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

Apple care is useless in India. I bought an iPhone 5 from a Maple store in June 2013. Also got convinced at the store and purchased an additional Insurance worth Rs 1000 at the same time. The iPhone 5 has a very poor battery life. Needed to be charged at

Apple care has been of absolutely no help to me. My 10 month old iPhone 5 stopped charging one fine day and Apple denies any responsibility for the same. Between my Family of 4, we Re currently using 5 Apple devices. Am so disappointed with the service from Apple. Although my cell phone is well within the warranty period , I have been denied a replacement. And the Shield Insurance that I purchased is now declining the insurance amount even. They insist I prove that it is an accidental damage. And Apple refuses to cover what they choose to call a 'physical damage'. So where does that leave me ?!

I cannot see the damage. But the screening centre has pics showing it is damaged. Apple refuses to cover a physical damage. But the reason the device is damaged could only be coz it had a poor battery life from start. The iPhone 5 is infamous for the same. We all know it. Apple conveniently denies responsibility.
And the Insurance company says it covers only accidental damage. Now how am I to prove an 'accidental' damage ? Unless I lie to them....

How to prolong my battery life

Hi guys. I had a 12 inch powerbook a few years ago and I had it plugged in for ages. Its battery was horrible and would last a matter of minutes. On my new PB (15") I decided I would use the battery sometimes. I would have it plugged in, and when fully charged I would unplug it. Then when I got to about 15% I would plug it back in. I have a widget that shows me the capacity status of the battery. After a year it was 80%. A month later, 70%. After a 2-week leave and another month of use it was down to 40% and 3 weeks later 30% where it has stayed for a few weeks now. I was about to buy a new battery when mine got recalled. Isn't that convenient? Anyways, do you guys have suggestions on how to prevent this fast paced degradation of batteries or will I have to dish out 120 bucks every year if I want a half way decent battery. Also should I calibrate my new battery?
thanks,
axel

Note Apple measures battery life by the number of
charge/discharge cycles, and not calendar time. They
say a properly maintained battery should retain 80%
capacity after 300 charge/discharge cycles.
Slight adjustment to that...measuring in cycles is not an Apple quirk. It is an industry accepted way to measure lithium-ion battery usage.
See: How to Prolong Lithium-Based Batteries
In that tech note you'll find that for laptop use, battery life is usually affected more by heat exposure than usage habits.

How to prolong battery life

How often should i calibrate the battery? does calibrating the battery more often help to prolong battery life? I usually leave airport on even if im not using the internet, so does that drain the battery life much faster than if I left it off? I use my laptop sometimes in class with airport on, but im not using the internet. And it went from 100% to about 85% in about 40 minutes. Text edit was the only application I had open. is this normal? Idk i might be wrong, but it just seems to me that my battery drains really fast. bluetooth is always off. at home even when its at 100% i leave the charger plugged in. is that affecting battery life?

How to calibrate:
http://docs.info.apple.com/article.html?artnum=86284
Do that for a couple of month or whenever you think the battery starting to behave erratically.
Some more explanation :
http://www.apple.com/batteries/notebooks.html
And 15% for 40 minutes is about right even if you using it only for text edit, considering the screen is on most of the time.
Yes airport consume power too, if you not need that for a long time (in class for 1 hour), turn it off. But some user posted that the different is only couple minutes only.
And new battery technology won't let you over charge the battery, so it still safe to leave it plugged let say overnight.
Good Luck.

Stop battery charging with plugged MacBook Pro

Hi,
is it possible to stop battery charging on a MacBook (Pro) with the power plug connected? I have looked into the PM api docs but cannot find anything to do that.
The idea is to make a menu app to toggle between "Preserve Battery Life" and "Full Power" modes. According to http://www.batteryuniversity.com/parttwo-34.htm, Li-Ion batteries loose less capacity over time when charge level is about 40% of max. capacity, escpecially with the comparatively higher temperatures that are given in a running notebook.
So the "Preserve Battery Life" mode would charge to say 50%, then let the MB run on battery to about 30%, then charge again etc. Before taking it on the road, one would switch to "Full Power" mode to charge the battery to 100%.
Thanks,
Bastian

Prolonging battery life

I bought an 11 inch MacBook Air a few days ago. I find the battery life isn't as long as with my other portable Macs, I just did a test, keeping the MacBook Air on, not letting it sleep or energy save, running Mail and iCal and occasionally using Safari, with the screen light about three bits along so not too bright and the keys not illuminated at all - the battery lasted 5 1/2 hours. I gather that is is quite acceptable for this MacBook Air as it's so small. My question concerns how to keep my battery life good. I normally use my computer at home, I simply want the ability to take it out easily and to take to different rooms in the house.
Should I run the MacBook Air on the plug almost always ? Or should I run it on battery whenever it gets charged fully and then plug it in when it's nearly empty ? Or doesn't it matter one way or the other ?
I note from Apple that there is no need to calibrate this type of battery - http://support.apple.com/kb/HT1490 - but there's no advice about how to prolong the battery life.
Anne

The general rules are, use the battery just when you need to, but do some periodic deep cycling to keep the battery in shape.
Here is a tech article from Apple that give some basic guidelines.

HT204054 How to prolong battery life?

The question is how to help the battery live its longest life--not runtime for each charge but how to prolong overall battery life??

"Full discharges put a lot of strain on the battery, and it's much better practice to do shallow discharges to no lower than 20 percent."
