Best way to maintain battery?

Hi,
I've heard a lot of conflicting reports about the best way to maintain ipod batteries. Does anyone have advice? I just got my nano yesterday and I would like the battery to last as long as possible.
Thanks!
Rachel

The following was copied from this link which includes a repeat of the other good information provided here.
http://www.apple.com/batteries/ipods.html
For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month. If you use your iPod infrequently (gasp), you might want to add a reminder to your calendar program.
A properly maintained iPod battery is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles.
With a Lithium-based Battery, I don't believe it matters if you charge the battery when at 50%, etc. The main thing is to go thru at least one complete charge cycle per month.
Check http://www.apple.com/batteries/ about charge cycles with Lithium-ion Batteries.

What is the best way to maintain your Battery Life for Iphone 5 ?

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 ??

What is the best way to maintain state in Java web apps?

Hi,
been looking at best way to maintain state between requests in JSP.
Ive been trying to use URL rewriting but been getting problems. I understand I can also achieve this using cookies.
Are there any other better ways of doing this.
I don�t know if the problem is with JBuilder4 or something in the Tomcat server?
Any suggestions would be appreciated.
thanks.

I think if you use JavaBeans that implements Serializable , it might maintain state (but not sure of this).
HttpSession is one option but , sessions have limitations - they timeout, they don't work when the page is cached by the browser and they don't work if Cookies are disabled in the browser.
Database is always an option, and there are two types of DBs , in-memory like HSQLDB etc , or the regular RDBMS like MySQL , Oracle etc.
If you only want to maintain state between HttpRequests, then use the request object which is implicit in JSPs.
I think your URL Encoding is not working most likely because you have disabled Cookies in your browser and that's why you see jsessionid.
If you enable Cookies in your browser then, the jsessionid should not appear.
There are other options I'm sure, but I'm only aware of the above at this time.... may be someone else might know more.

Satellite U405 - What is the best way to increases battery life

Hi everyone!
I've been looking for this quite a bit and all I could find are conflicting answers and some confusing instructions... :)
Even the PDF file for my U405 has some conflicting tips (is it recommended to fully discharge it or not?)
Let's say that I don't want to remove it and store it with a 40% charge in a low temperature location (?) because I also want to trust it as a UPS (power failures are common where I stay).
So, in short, what is the best way to prolong my battery life to its maximum? Should I fully discharge it once a month or only half way through? Should it never be fully charged or that's actually a good thing?
Thanks in advance for any wisdom anyone can offer on this!
David

The best way would be indeed to put it out of the notebook, but you already said, you won't do this.
So, I would say to fully unload the battery once in a while and load it to a maximum.
This is all I can tell you right now, but don't know how much this will increase the battery's life.

Best Way To Optimize Battery Life?

Just got my new iphone and I'm just wondering what the best way to optimize/charge the battery is. With other cell phones I've been warned about overcharging (keeping it plugged in once it reaches 100%), and I've heard that this is not the case with the iPhone's lithium battery. Is this true?
Also, I've been hearing that I should avoid letting the battery drain and to charge it whenever I get the chance rather than waiting until it's getting close to dying. Once again, with other cell phones I've heard the opposite of this. Is this the best strategy?
Thanks!

Yes to both.

To create or access a second (or more) library on a Mac, hold down the "Option" key (labelled ⌥ and/or alt) when launching iTunes: Using multiple iTunes libraries -Mac
Note: You can only have one Library open at a time and iTunes will default to the last library opened if you don't use the keyboard command to choose one.

What is the best way to maintain my battery?

What is the ideal charge cycle to be maintained?

Here's what Apple says:
http://www.apple.com/batteries/notebooks.html
Now I'm gonna share a dirty little secret about all lithium batteries: Fact is, the biggest killers of these batteries are frequent full discharge/recharge cycles & heat. I'm well aware what Apple recommends, but I'm telling you that if you want your battery to last avoid discharging below 35 ~ 40% of capacity as much as possible & avoid heat. Every 3 ~ 4 months, it's OK to discharge to ~ 35% of capacity & then recharge to full. More often than that is not needed & will do more harm than good.
The battery in the MacBook Pro I'm typing on right now is over 5 years old & still going strong...long past its rated life span. Don't know how much longer it will last, but if you keep in mind the biggest killers of these batteries, & act accordingly, yours will last as well.

What is the best way to maintain models with common components?

I work for a company that uses MatrixX/SystemBuild (v62.2) to build functional models of trains for use in driver training simulators. We are currently in the early stages of a project in which we will need to build and maintain multiple train models which are likely to have some common components, but may have some significant differences. Before we get too far into the modelling, I would like to come up with a decent method of maintaining the common components while keeping the differences separate.
Ideally, I would like to find a way of quickly and easily determining the difference between two models and a way of conditionally pushing the differences from one model to another - in a similar way that one might diff two text files and conditionally copy the changes in one to another.
I found a script (mx_62.2\sysbld\scripts\compare_catalogs.msc) that seems to accept two catalogs for comparison, outputing a difference log. However, I'm unsure how to use this as I don't know how to load two catalogs within the same instance of Xmath or how to assign a catalog to a variable for passing in to a function. Does anyone know how to use this script?
I am also thinking that it might be useful to be able to convert a catalog to an xml - I can probably write a script to do this, however I am wondering if there's anything freely available to do this.
Does anyone have any other ideas?

Let me first discuss about comparing models, then I'll talk about my ideas about modularization.
Comparing models in anything before v8 is difficult. In v6 or v7, there's no way to load to separate files containing the same yet different superblocks. The tool scripts you found don't seem to be documented anywhere. Given the history of some of the things added into the product, I'm not surprised. Which means that it's useless to us. After looking at the scripts, it's difficult to figure out what the inputs to that script should be. You can launch multiple instances of xmath/sysbld and load the models separately, but that's about it.
One suggestion if you have to compare models is to use the exportcatalog.msc script which will generate a text file containing the SBA commands to re-create the model. Do the same for both models then perform a text difference between the generated SBA commands in the generated files.
Another possibility is to use SBA to get the details of each superblock (similar to exportXXX.msc scripts) into a form that's easier to compare between. I'm going to guess that some kind of generated SBA content is the expected input to the compare_catalogs, but I'm not sure.
Now, within v8, we've created a hierarchical compare tool, that compares model files and shows differences. Copying changes between the compared models is a future enhancement. However, in the context of using v8, you could manually copying the changes between the models using the editor and/or project system as appropriate. Yes, in v8 you can separately load models containing the same named superblocks. Try it, I'll bet you'll like it and it will save you lots of time!
Now, on to modularization. I'm not sure you're use of 'components' is the meaning of the Components feature in Sysbld or not. I'm going to assume that you are not using Components and you're generically using the term components as a set of logically related superblocks, or as I perfer to call them, a module.
The only modularization tool you have in Sysbld is the file. What I mean here is that you are able to group sets of superblocks into separate savefiles (.sbd) then combine them to create a complete model. So, essentially, you will need to partition your model into modules and each module is a separate savefile. Then, you can choose which module (i.e. savefile) to load to construct a complete model.
In v8, there's a project system specifically designed to make this kind of modularization within a project easy and straightforward to use and maintain. I'd suggest that you use v8.
For previous versions, the best you can do is create xmath scripts for each complete model you need. The script will contain all of the steps needed to load the separate modules to make a complete model. Thus, you'd have a different script for each model. Also, becareful in v6,v7 that you'll have to manually manage which superblocks are part of which modules, it's tricky stuff. Again, you'll need to use scripts to help maintain this level of complexity in these versions of the Sysbld.
Now, I do not want to recommend FileSuperBlocks, it's a legacy feature to deal with limited resources not applicable on today's machines.
Also, I can't really recommend the the Component feature in Sysbld. It's really not a component, but more of an object, sort-of. And it sort-of gives you unique names and it sort-of gives you parameters. It will not help with the modularization I think you want so don't use these.
In general, there are features within our latest v8 release of MATRIXx that will help you with all of your issues. If you can, upgrade!

What's the best way to preserve battery life?

I know obviously make sure your backlight isn't always on and keep Wifi off, I've read www.apple.com/batteries throughout.
I'm talking about preserving the battery itself.
Like is it better to let the battery run all the way down before you recharge it or charge it as soon as it gets around 40-50% or every couple of days?
I have my blackberry which I charged every night regardless for months and months and now about a year later, the battery is basically crap and I'm lucky if I don't have to charge it every night now.
Same concept apply?

Yup, the backlight is the biggest battery drain.

Rechargeable batteries don't last forever. I supervise a cell phone repair department. We generally tell customers that, with average use, a battery will last about a year. Heavy users, it can be six months. Many Blackberrys have big screens, too. Over time, no matter what you do, a rechargeable battery will lose capacity and eventually, not hold a charge. At least your Blackberry has a user replaceable battery and you can pick one up for less than $40 dollars!
Best of luck.

Best Way to Retain Battery?

I've done some research and gathered that most people think that it's better to let you macbook sleep than shut it down all the time, but now I have another question... Is it better to run the battery down all the way then recharge all the way or just charge whenever or leave it plugged into the wall whenever possible? I want to keep my battery at it's best. Thanks

+*I got the idea from the cell phones, some where I read or heard that it is better to let it drain all the way down and recharge it all the way up , because then it messes the charging cycles and I have seen it happen.*+
Actually, that's not quite correct either. Cell phones for pretty much their entire existence (maybe excepting those when they first came out nearly 20 years when they were carried around in little bags) have used lithium ion batteries... pretty much the same technology used in the batteries in your MacBook. While it was true for older battery technologies such as nickel metal hydride and nickel cadmium that you needed to fully discharge and fully charge the batteries each time... this is no longer the case with newer battery technologies. The older batteries would exhibit what was called a "memory effect". If you regularly only used half the capacity... it would eventually only hold half the capacity. This is just one of those things that has been handed down from the good old battery days and doesn't seem to want to go way.

Best way to extend battery life?

I have been using my IPAD with it being plugged in when I can. I feel this may help to prolong battery life than for the battery to charge/discharge so often. Any thoughts? Thank you!

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%.
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. Also look at The iPad's charging challenge explained http://www.macworld.com/article/1150356/ipadcharging.html
Also, if you have a 3rd generation iPad, look at Apple: iPad Battery Nothing to Get Charged Up About

Best way to charge battery of macbook air

i have a macbook air 13 inch 256 GB SSD. it is early 2014 version . i bought it in dec 18 2014. i have had 11 charge cycles up until now. the issue is that my battery full charge capacity has dropped from 7280 mah (100%) to 6818 may (95%) in a span of just 9 days . i fail to understand how it can be normal? my battery usage is normal . i charge my battery and take precautions as not to overcharge it . so once my battery is 100 % charged then i disconnect the cable and let the MAC run on battery. i do so because i have heard from many people not to keep the machine always plugged on charge. i want to know whether the % drop in my battery flu capacity happened because of my faulty charging practice? . please some expert tell me as what is the correct way to charge and use the MAC battery as i want to use it in a proper way . there is no constraint in my case as i normally use my MAC at a place where i keep it plugged all the time.
thanks

Hello!
This sharp drop in F.C.C. isn't normal no matter how you use your battery. The degradation of the F.C.C. should occur slowly over the span of months, not days.
Please reset the SMC to make sure that it's not an reporting error of the hardware: Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support
If the degration keeps happening this fast, take it to an Apple Store.

Best way to preserve battery?

I just got a new macbook and I was wondering which of the two scenarios will best preserve my battery for better quality, or if it makes a difference at all:
1) Charge my battery to full, unplug, use up battery to empty, and plug in to charge to full again. Repeat cycle always.
2) Keep my macbook plugged in at all times when possible.
Thanks everyone.

I will try and answer your first question as best I can, as I am not completely sure about this.
What I have heard, is that the computer runs completely on the power adapter when plugged in. But the charger is also charging the battery at the same time. I'm pretty sure that the MacBook's power adapter, has two circuits inside. One is for powering the computer, the other is for charging the battery.
Your second statement is also partly true. The battery that is used in all current Apple notebooks are designed to automatically be used on battery no matter what from time to time. This is to help prevent the battery from dying a premature death by being plugged in all the time. What happens is that when the battery reaches the fully charges state, the computer begins to run on battery power, while still plugged in, but only for a short time. (Something like 3-5% I think.) This is to make sure that 1. the battery does not overcharge, and 2. the battery's ions move around a bit. (That keeps a battery healthy, thus, using the computers battery is good for it...)
Your third statement is also partly true. Batteries are only perfect for up to 300 charges, or so Apple says. Once you get to 300 cycles, the battery is not dead though. Apple states that all of their batteries are designed to hold about an 80% charge at full capacity once they reach 300 cycles. This said, your battery is going to die weather or not you leave it plugged in all the time, or use it like it is intended to be used. I for one recharge my battery whenever the low battery warning comes up, I don't wait for the computer to go to sleep, or I recharge it when it is low if I know I will need it later.
I still stand behind my recommendation that not leaving a battery plugged in and using it normally, will allow it to9 last longer than leaving it plugged in all the time. Here is a real life example that I personally have seen: My dad purchased a Gateway notebook 5 years ago, he has it plugged in all the time. My aunt purchased a IBM ThinkPad about 6 years ago, and only plugged the battery in when it died. Guess what, my aunt's old notebook runs on battery for almost 3 hours after 6 years, my dads battery on the other hand last about ~30 minutes at the most.
