How to increase battery HEALTH

i checked my battery health after installing istat pro today, and it said my battery health was currently at 46%. how can i bring that back up if that's even possible?

The MacBook Power and Battery forum is a better place to ask about this:

How to increase battery life, and how this could be automated by Apple

This is something I submitted to iPhone feedback via their webpage. I thought that some of the suggestions (if you do them manually) would help out with battery life a bit, obviously disabling and enabling services all the time is a pain, but it will for sure help, and if it was automated that would help as well...
There are several settings you could add to the iPhone that would greatly increase battery life for users
1. Have the GPS radio shut off after a period of inactivity from the accelerometer, if the iPhone isn't moving there is no point in wasting battery life keeping the GPS radio on, have it remember the last position before shutting off to help speed up location reporting once the iPhone starts moving again.
2. Have an options screen that allows users access to all the iPhone services that consume battery, this would make it easy to understand what services use battery and will make it easy to disable those that are not currently required, order the list with the highest battery consumer at the top and the lowest at the bottom, this way people will understand that disabling those services at the top of the list will get them higher increases in battery life. Currently to toggle the battery consuming services requires visiting several menu screens, some several layers deep into the settings pages, people don't bother doing this and thus complanin about battery life.
List of services to include on this page at minimum:
Push, wifi, wifi auto ask to join networks, bluetooth, 3G, location services, notifications, ringer/vibrate, screen brightness, time to sleep, airplane mode
Would also be good to be able to schedule ringer type/volume/vibrate, a lot like profiles on the blackberry.
3. Have the option to schedule times for various battery consuming services to be available. I don't have wifi at work, i would save battery life if wifi was automatically disabled between 9am to 5pm, sure i could do this manually every day i get into work, but most people won't, if they can schedule it then there is no worry that the iPhone will always only be running those services that are required at the time. Of course there needs to be a manaual override in case something changes, like lets say i don't go to work on wednesday i would want wifi on for that day. Would be best to have these programable services on a 7 day schedule, or at least 5 weekdays and 2 weekend days, but the ideal is obviously that each day can be set seperately and accomodate all sorts of life schedules, just like a 7 day programable thermostat.
Currently a lot of people are complaning about battery life, mostly it is because they don't know what to do to conserve it, or they are too lazy to change settings all the time based on current usage and service requirements. Adding these functions would give people the ability to bettery manage the battery life on their iphones and would help to reduce the amount of complaints.
Thanks very much!

Actually it is already that way. GPS radio is usually off, unless needed by applications. The problem is that many applications need it (including free apps that include geo-location based advertising) and that's when GPS works some extra. There's also another factor in making GPS drain battery: it is not the GPS radio itself, but communicating with apple's Map server while using it even if you're not looking at any maps. The thing is that location services rely on some information that can only be obtained through communicating with a geo-location server. Which is another drain factor.

Unfortunately it is not that straightforward at all. It depends too much on the type of network you're using and on many other factors. It is impossible to have a reasonably reliable ranking like the one you're suggesting.
What could be useful is to have a single switch that controls all services that rely on persistent connections (push, application notifications, some other things) but it is not that trivial at all.
3. Have the option to schedule times for various battery consuming services to be available. I don't have wifi at work, i would save battery life if wifi was automatically disabled between 9am to 5pm,
Having WiFi on while having no WiFi coverage consumes, err, well, almost nothing. Especially in standby, when the phone keeps WiFi radios off at any rate. WiFi is the least expensive bi-directional radio and iPhone manages it very well.

A lot of people are complaining (including myself) because *it does not work right*. Not because I can't switch things off when I don't need them.

How to measure battery health?

My 1-year-old iPad 2 seems to hold significantly less charge than it did when it was new. I know that Apple has a 50% health threshold for warranty service, but is there any way I can see that number without a journey to an Apple Store.

I was prepared to say that the app recommended above wouldn't do the job but after looking .... maybe it will, in the way it approaches things, but I don't think you really need it.
The only way to really know the state of your battery's health is through how it performs in normal use, which is the only spec that is provided by Apple. The test you go through is a multi-stage one, as follows:
Run your battery all the way down, in normal use, all the way until the iPad shuts itself down.
Now re-calibrate your battery metering by plugging it into a known good charging source, for which read the Power Adapter which came with it, and charge it all the way up to 100%. It will take a few minutes before you see and hear your iPad come back to life.
Once it reaches 100%, leave it overnight. The next day, just use it like you normally do, do whatever it is that you normally do; but keep on doing it until the battery goes flat and shuts it down agaion. Make note of how long this took. The average user should expect about ten hours of use out if it, on wifi, less on cellular, depending on how heavy your video loadng is.
The recalibrating needs to be done every month or so to ensure that the metering (the percentage that you read) remains fairly accurate. If you fail to do that, eventually it will no longer be.
If you get less time before it shuts down, try it again. If you consistently get much less time than you should, then you definitely have a battery capacity issue and need to start talking to Apple.

How to check battery health..

My battery seems to be having issues.. How do I check the general health of the battery?

I'm in a similar position. I was told about a widget you can download for the dashboard called istat nano.
It gives you a health percentage of the battery as well as other diagnostic details about the mac. The only thing I'm unsure about is how accurate the information it gives you is.

How to INCREASE Battery Capacity

Just drop the advertising - I know that battery capacity varies, and that the capacity of the phone battery - regardless of models, will degrade as the phone is used.
I contest the "specialists" to provide some straight simple guidelines to how one can treat a battery to increase the capacity.
That the layers gets closer and short-curcuits is a known reason. So, exposure to heat will make the substance that keep the layers apart into gas that escapes the battery. Now how can such a battery be fixed? In old days with NiCd we could freeze the battery to -36C, that would make the iodine to solid. if iodine is still used, this will still work. Other semiconductors needed more than -100C to regain state - but with access to liquid Nitrogen, that was fully possible. Maybe Ni is not so common, but freon is, and LPG (Butane/Propane liquified). A home freezer can at times go as low as -38C.
So, can charging in heat / cold change the capacity of the battery?
Other: If I completely drain the battery between every charge - will that improve it?
If I start to recharge it when it is 80% of capacity, and disconnect immediately and use everything, Bluetooth, WLAN - to drain it to 80% and the recharge - can I restore the good old capacity?
if the battery degrades to 10% of capacity, is it possible to restore it? How?
Don't change anything that works.

That, and I've been reading to not constantly charge it, or leave it in at 100%. It can be charged too much from what I've seen. I've had mine since 2006 almost 2 years, and till recently left it charging all the time. Not sure that's been a good idea. This is Battery University website information...
gure 1: Permanent capacity loss of lithium-ion as a function of temperature and charge level.
High charge levels and elevated temperatures hasten permanent capacity loss. Improvements in chemistry have increased the storage performance of lithium-ion batteries.
The mentioning of limited service life on lithium-ion has caused concern in the battery industry and I will need to add some clarifications. Let me explain:
If someone asks how long we humans live, we would soon find out that the longevity varies according to life style and living conditions that exist in different countries. Similar conditions exist with the batteries, lithium-ion in particular. Since BatteryUniversity bases its information on the feedback from users as opposed to scientific information derived from a research lab, longevity results may differ from manufacturer' specifications. Let's briefly look at the various living conditions of the lithium-ion battery.
The worst condition is keeping a fully charged battery at elevated temperatures, which is the case with running laptop batteries. If used on main power, the battery inside a laptop will only last for 12-18 months. I must hasten to explain that the pack does not die suddenly but begins with reduced run-times.
The voltage level to which the cells are charged also plays an important role to longevity. For safety reasons, most lithium-ion cannot exceed 4.20 volts per cell. While a higher voltage boosts capacity, the disadvantage is lower cycle life. Figure 2 shows the cycle life as a function of charge voltage.

HT4275 how to increase battery life

My battery life suddenly decreased substantially. Just in the last couple of days

I've seen the same phenomenon as well. The trackpad batteries sometimes last a month or more and then suddenly they only last 3 days. I haven't pinned down what's causing the devices not to go into low power mode yet, but certainly a software bug. Until then I use rechargeables and always have some ready.

How to increase your battery health - anyone with similar experiences?

this is my very own self made instruction of "how to increase your battery health"
it is the procedure how i have done it serverall times on my powerbook g4 12".
my stats: 374 cycles, health 86% (3790 of 4400mAh)
age of my mac: 57month (battery bit newer)
**if you to try this: it is on your own risk!**
**this may not be suitable for mac newbies**
**be sure to read this twice before you do it once!**
you will need:
-a pocket lamp or comparable light (to see anything on your sreen when it is dark --> light from the back through apple logo)
-coconutbattery (coconut-flavour.com/coconutbattery) or comparable programm to track your battery information in realtime
-activity monitor
-cool enviroment (to ensure your fans don't have to work that much)
-some time and patience
the intructions:
step1: load your mac until the orange light turns green
step2: disconnect the power adapter
step3: use your mac until 15-25% battery life (track this information in your menu bar)
step4: slow down your activities. the order of the following actions depend on your usage of your mac:
__close programms that use lots of cpu/gpu to ensure the fans slow down to 0rpm (!!)
__turn off everything that needs battery power: airport / bluetooth / speakers / etc.
__eject dvd or cd
__close all programms with important data
__eject idisk / .dmg files in your finder (this is not only a matter of data security)
__dissonnected from peripherals such as ethernet / internet / mouse / keyboard
__use lower brightness level
__open activity monitor to ensure that your hard drive activity is very low, may be you need to close more active programms, close activity monitor when hard drive activity is very low
__open system preferences >> energy saver preferences >> choose longest battery life
when your are ready with those actions go on and ensure you are able to connect to power adapter with your mac quickly (be able to charge - don't do it yet!)
step5: be patient. now it should take some time until your battery level goes down to 3-5%
now there should be no programm running.
do not open any programm now!
do not have a look at your dashboard!
now your mac should be really quiet:
-no fans (0rpm!)
-nearly no hard drive activity!!
-->> if this not the case break go on with step 11&12, try again in a week or two
-->> if you are ready go on with step6
step6: open coconutbattery und use the lowest brightness level
play with your trackpad to ensure your screensaver won't start. waste time until you are at 1-2% battery life.
step7: take your lamp and spot through the transperent apple logo, position your coconut battery window somehow that you can see the current battery charge und the maxium battery charge in the spot of your lamp through the apple logo.
step8: go from the lowest brightness level to the level under the lowest brightness level (a dark screen)
step9: watch your current battery charge carefully und keep on playing with your trackpad to ensure your screensaver won't start.
step10: there is kind of battery buffer made of approximately 1% (once when my "current battery charge" was 3624mAh and this kind of buffer was at 36mAh)
to empty this kind of battery buffer takes much longer as you might expect!
when your current battery charge turns under this kind of battery buffer, your maximum battery charge should change. hopefully it is higher or stays the same. when it is lower now: i'm sorry - i have warned you. may be you have to go through this 'how to' more carefully!?
step11: plug in your power adapter before the battery is cero!
step12: load until the orange light turns green
step13: if it was helpful do not repeat it more than once a week, better once a month

anyone with similar experiences about increasing battery health!?
(yes, i'm sorry for my poor english, i've tried my best)

Me too! My battery lasts for 10 minutes. It is awful and I am on my 4th power adapter since they keep breaking too.
From coconut battery: Maximum battery charge 310mah, original 4400, age of mac 45 months, 140 cycles.
From system profile:
Battery Installed: Yes
First low level warning: No
Full Charge Capacity (mAh): 310
Remaining Capacity (mAh): 213
Amperage (mA): -1205
Voltage (mV): 11557
Cycle Count: 140
I went to an apple authorized retailer and they said nothing I can do if it is out of warranty.. is this true?

How to increase the battery life of your N series ...

What I am about to post here is valid for any 3G phone or device regardless of model but it is particularly focused towards the N series devices and their power hogging features.
Your battery life is dependant on many many things. How often you take calls on the device, the condition of your battery, the features you use on the device and so on and on. Therefore it is impossible to say that by following the information in this post you will get x amount of days battery life, but it will get you more time out of the battery than you otherwise would have got.
So with that out the way, if your looking to increase your battery life then follow these tips and your battery should start looking a lot healthier.
First of all lets start with THE big one. The one that is going to save you the most juice. Switching 3G off.
Yep, you heard me right. Just by switching the 3G capability of your phone off you will add hours and hours to your battery life. How is this so? Allow me to explain...
Due to the rather poor delivery of 3G in the UK by the network operators, it is rare for any 3G phone to maintain a constant 3G signal. Instead you will find that the phone constantly flips between 3G and GSM mode (Keep an eye on your signal one day). Even those of you on Vodafone who probably have the best 3G network coverage will find this is the case.
Unfortunately, this constant flipping between the two modes sucks power from the battery like a vampire as it alters its reception state for the different modes and the constant flipping is..well...causing it do this constantly! It can sometimes even make your phone unavailable for calls for very brief periods as it trips from GSM to 3G and vice versa.
If you need to use 3G for video calls or whatever then I'm afraid your just going to have to live with this but if you don't (And lets face it few of us do) then you can switch 3G off and increase your battery life considerably.
To do this, go into the "Settings" application (Found in the menu somewhere, by default Nokia normally stick it in "Tools"), and then to the "Phone" tab. In there you will see an option that says "Network mode" and you have a choice of "GSM" or "Dual Mode" (I.e. UMTS and GSM). Set it to GSM and your phone will restart. Once it restarts it will be working in GSM with GPRS speeds only but really for most purposes this is fine.
You have now just extended your battery capability considerably. You can further extend it by going to the "Connection" tab, going into "Packet data" and changing it to "When needed" so it is not constantly checking for a data connection.
The second big change you can make is to turn your phones wifi scanning capability off. The last time I looked not all Nokia's phones that have wifi capability can have their wifi cards switched off entirely but if you can, turn it off except for when you need to use it. Wifi is a power hog.
The next big change you can make is to lower the screen brightness settings on your phone. The less bright your screen is the less power is being used to light it up. Nokia by default leave the screen brightness at something like 50%. Lowering this a bit more will conserve more juice. Before you do this though please consider the fact that lowering the brightness setting will have a big impact on your ability to see the screen clearly in sunny conditions although you will be fine in the dark as you can't lower the brightness that far.
To lower the brightness, go to the settings tool in your phone and into the display option (Hidden in a subcategory called "Personalisation" on the N95). It won't hurt to set the power saving time out to 1 minute and the backlight time out to 10 seconds while your here (Although these are the Nokia default so they should already be set to this).
Finally in regards to the screen, although they may look pretty, animated screensavers use more battery power than the standard blank screen with time and date so avoid them if you can.
It also helps to keep Bluetooth switched off until you need it although the power savings are minimal in comparison to the other changes but every little milliamp counts!
Using the above methods I generally get about 3 to 4 days with about 3 hours talktime on my N95 without using Bluetooth, GPS or anything like that (I might be able to get more but so far I have not paid attention to the battery state before I put it on charge). If I am on a long train journey I can get about 4 hours worth of full screen video and about 2 hours talktime over the period of about 24 hours before it needs a recharge. As I said at the start of the post your mileage will vary greatly depending on how you use your device.
Hope this helps.

no keffa it is a cop out from nokia
its not unfai as its a premium device with a premium price
the n95 battery is atrocious
dont change the post content as the title is 'How to increase the battery life of your N series device'
your talking about nokia phones specifically
the networks are not to blame
they do not make the handsets : Nokia do !!!!!!!!!!
I'm going to choose my words carefully here...
I would never deny the battery on the N95 is not really up to the job of powering the N95 with its power hungry features. To put the same battery into a phone that has WiFi, GPS and a large 320x240 screen, the same one that goes into the E65 which has comparatively nothing compared to it is a bit pants.
However at no point was I criticising them for the band hopping problem. I labelled the post as how to increase the battery life of your N series device because this is a board for the N series devices. It was a simple choice of wording and not intended to be cutting in any way and I did make a remark that the details would be true of any 3G device at the top of the post.
What I was trying to point out in my second post is that the constant band hopping the phone is being forced to do that is draining its battery so much more quicker than it would if it had a constant signal of one kind or another isn't quite Nokia's fault.
They build it to conform to a laid out specification for 3G. However if the network operators cannot be bothered to roll out their 3G infrastructure adequately enough that the phone can find and remain locked onto a 3G signal that is usable then what are Nokia to do other than offer you the capability to turn 3G off until you need it (Although note to Nokia: That **bleep** reboot the phone does when you do this is entirely unneeded and you know it).
Blaming Nokia for this would be like blaming the manufacturer of your radio for failing to pick up radio because the radio station does not have any transmitters within range of your radio's receiver.
Finally...this band hopping is exhibited by all 3G phones built by Samsung, Nokia, Sony Ericsson, etc, from their most budget 3G model to their priciest piece and is the reason that all phones with 3G capabilities have batteries that do not last for any respectable length of time because these phones are also having to band hop between 3G and GSM.
Finally the proof is in the pudding. Turn 3G off for a few days. See your battery improve. Then (Although admittedly this will be harder to do...mcuh harder) find an area where you get a fairly decent 3G signal constantly. Again, see your battery improve. Try it with a different 3G phone...different manufacturer even. The same will be true.
So I stand by my comment, the network operators and their woeful 3G rollout are the villains costing you a fair chunk of your battery and Nokia cannot be expected to mitigate this....but a better battery would be nice all the same...

How to turn on Optimized Battery Health Mode

I recently bought a G505 laptop and a popup window tells me I should use the "Optimized Battery Health Mode".
However, nowhere on the popup does it tell me how to do this.
I have searched online and also with the Lenovo Solution Center and find there are all kinds of battery modes
that are spoken of and various ways to access them. However, I cannot find "Optimized Battery Health Mode" anywhere!
I see "Balanced Mode" and "Power Saver Mode" but no "Optimized Battery Health Mode" anywhere.
If I go to the Lenovo Solution center, I cannot find battery settings anywhere under the system tab.
Can anyone tel me how to get my G505 laptop into "Optimized Battery Health Mode"?
Many thanks!

I finally figured it out. If anyone else needs to do this here how I did it.
1) Right click on the battery icon on toolbar, then choose power options
2) From here click on "Change Plan Settings"
3) From here click "Change Advanced Power Settings"
4) This opens up a small window, choose the "Lenovo Energy Management" tab on top
5) Click the "Enable Lenovo Energy Management" button
6) This opens up yet another window with the option for "optimized Battery Health"
Wow, they sure don't make it easy do they?

Having serious issues with battery health, how could it be?

hello,
newbie to this forum but not to apple devices.
my big brother gave me his MacBook Air about 2 months ago. he bought it in august of 2009. when i got it, it ran Windows 7 (dont ask me why that what he wanted). i did update to the system and installed snow leopard etc...
after install the iStat pro i noticed that the battery is in good condition, 93%. i thought he ruined the battery cause he always plugs his laptops/netbooks to a power source.
i dont understand why but in the first month i had 90%-92% health, and in the past few weeks it went down to 88%-90% and a few days ago it was 86%. today i went to school and when i opened my mac the battery health os on 84%!
i really dont understand why.
i follow the instructions and wait until the battery is empty, recharge to 100% and again waiting... etc... there is no overuse and when im home i usually work on my stationary computer.
the computer overall is in great shape, i dont understand the problem maybe one of you guys can help a brother out...
thanks in advance!!!

hello,
newbie also to this forum, does anyone can confirm that when the battery gets older, the maximum load percentage will decrease so that 100% capacity will never be reached anymore?
Tks.

MacBook Pro 13'' late 2011 battery health problem!!! HELP!!!

I have a MacBook Pro 13'' late 2011.
It's this normal? How do I increase my battery health?
Can I change my battery?

When did you buy it?
Do you run it down to near zero % before recharging? Which is a bad thing to do.
Do you charge it to 100% before you take it off the charger?
Do you always disconnect the charger once it reaches 100% even if you are right next to an AC outlet. Which is a bad idea.
Batteries only last so long. Over use it and it will go bad sooner.

How to improve battery life??

hi this is siva bought g580 2 days back everything except battery backup is up to the mark .........though it is a new one my battery backup is only 2:30 hrs could u please provide me with a solution to increase my battery performance to the level as stated in lenovo website(5.5hrs)

Hi
Welcome To Lenovo Community
We are really sorry to hear about the issue you are facing,
Fully charge battery, then unplug & restart the system and Enter BIOS setup. (Press F2 key at Lenovo screen.) , Let laptop sit until it shuts off, and note how long it runs.
Or you may also try Battery Gauge Reset
Open the Lenovo energy management, and where you have the options for Optimize for battery health or battery run time, at the bottom it says
Battery Gauge Reset
Start.
click it and do the on screen instructions.
Do give this a try and let us know
Hope This Helps

Battery health decreased rapidly after charging problems.

Hy a few weeks ago the health of my mid 2010 MacBook Pro was still 79% which is normal since it has more than 1000 cycles.
Then following incident happened:
My battery was almost discharged, 30% or so, so I connected it to the AC power. After a while I wanted to see how much it was charged but the indicator in the corner still indicated the same 30% or so, only when I disconnected it it changed to something in the 80% range. I used my computer for a while like that and I noticed that the battery indicator was not chaning. Only when I connected or disconnected the AC power did it update.
I decided to reboot the machine and this solved the problem. I recently noticed however that my battery health now dropped to 63% which seems very much in a short period of time.
I know that normally charger will deliver less current to the battery when it is near 80% in order to prevent overcharging and maintain battery life as much as possible. I wonder however if the drastic decrease could be because of the power management thinking that the battery was only partly charged and thus delivering to much current to an almost full battery? If this is the case do you think that Apple would intervene for the costs of a new battery? I know I would have had to replace it sooner rather than later but this does change a lot I think. My computer is not in warranty anymore and I don't want to pay 49€ for one intervention. There are also no official Apple stores in Belgium and the authorised resellers really don't offer the same service.

sweex,
since your battery has over 1000 cycles and has 79% of its original full charge capacity remaining, Apple considers your battery “consumed”; they will not intervene for the cost of a new battery. It’s entirely your decision when to replace your battery, but irregular charging results are to be expected for as long as you use your present battery.
If no Apple-authorized service center in Belgium offers the option of changing the battery, then you should let Apple know so that they can find an organization who will do so. I don’t know where you are in Belgium, but this search around Brussels shows seven different Apple-authorized service centers which all claim to service Macs, and the one in Aalst is noted as being a Premium service center.
