Re: Battery Use Question...

Hello all -- Well, I've got my new battery for my Powerbook G4 1.67 now after going through a second one in less than 8 months. So my question is this:
- Does it make sense to remove the battery when I am able to plug in the A/C adapter to the wall? This way, I don't run up the Cycle count and reduce the battery life when not necessary?
- Does the computer slow down if the battery is removed but plugged into A/C power?
Thanks,
Jason

When the PB is plugged into the wall, you are not running up your cycle count, unless it's recharging, which it would need to do in any event. If you haven't already, you might read these two Apple notes, the first on what constitutes a cycle: http://www.apple.com/batteries/ and this note on Powerbook battery maintenance: http://www.apple.com/batteries/notebooks.html . Note that lithium batteries need to be used, to maximize their life.
Your system speed doesn't change with or without the battery when plugged into the wall.

Battery Use Question

Is it better to plug in whenever possible? I know for other types of laptop batteries it is bad to do that. I guess what I'm asking is what is the appropriate way to use the battery power (only when necessary? always drain it?)

As you may aware that the battery for MBA is "irreplaceable"
You can replace the battery in a MBA yourself. Just follow these instructions.

Battery uses with iOS 4.2

Hi,
I have noticed a battery use issue after upgrading to iOS 4.2 My iphone and ipad battery is draining quicker than it did before the upgrade. For example, if my iphone (Model 3GS, 1.5 year old) was charged full and left idle for 24 Hrs, the charge drops just a few percent. I used to get 90-96% charge remaining after one day idle. Similarly, in ipad too, the charge will retain 85-95% if left one week idle after full charge. But after updating to iOS 4.2, the battery is draining quickly. iphone charge drops to approx 80-85% if left idle for one day and by 3rd day it drops to 20% if left idle. Similarly in ipad too the charge is dropping faster too. If kept idle for one week charge drops to some 70%. Did any one notice this? I am unhappy with this issue as it requires me to charge the devices quickly. Also the drain in charge is unreasonable as i have not used any extra feature which may use more energy.
Thanks,
N

Are you sure? I'm using 4.2.1 and don't have any battery issues with mine.
Did you check that nothing is running in the background? Some apps like Skype can still run in background even if you exit out of the app.
Also try this:
Delete your mail account by going to Settings > Mail. Once deleted, do a hard reset, by holding the home button and the power button for 10-15 seconds until apple logo appears. Then re-set up your mail account. Sometimes the mail server can get stuck.

Speakers for the iPod running on batt, do they cut battery use in half?

I know that volume has a lot to do with battery drain on a battery radio, and I imagine it is the same with the iPod. How much drain do speakers (the kind specifically made for the iPod) cause? Do they cut the battery useful time down to 2 hours? 1 hour? before needing to be re-charged?
I'm interested, but not if they are a huge drain on battery life. How do they compare with drain caused by ear buds?
Let's say all of this would be at a moderate volume, not loud.
Thanks for any input on this,
Ken

No one can give you a definite answer on this. Every speaker uses electricity at a different level so the only way to know is to call the manufacturer and test them out yourself. I can say that it will drain a lot of your iPod's batteries if it uses your iPods batteries in the first place. Usually speakers have a power source of its own so you can plug the speaker's adaptor to a outlet on the wall.

Battery use by the APP GPS Status & Toolbox...What's Up with this APP???

Thursday - 12/15/2011
All,
When I turned on my phone this morning I decided to check my battery usage and what a surprise. But first let me say that in all the time my Charge had Froyo 2.2.1 and also using GB 2.3.6 my battery usage ALWAYS had "Display" as the biggest user of the battery. See attached Screen Shot
This morning the APP GPS Status was the biggest user of the battery even more than Display. I did check to see if GPS Status was running and it was NOT running. I have not even used GPS Status for several days.
What's up, does anyone know??? I hope this APP is not a stealth off spring of CarrierIQ!
JerryF
PS, After using the phone I re-checked battery usage about 3 hours later and Display was again the biggest user at 51% and now GPS Status is in second place at 19%.

Richs10 and OTHERS,
I think I figured it out and it appears that GPS & Toolbox is NOT constantly running and is no longer using battery power. It seems that once you use an APP it appears in the "Battery USE" display. Look at settings>about phone>battery use if you want to see your Battery Use display. Therefore, when you use an APP and it used a lot of battery juice it goes to the top of the Battery Usage list even though it is NO LONGER running.
It stays there until some other APP tops it as the biggest user or battery power or the Battery Use list is reset..
That said, go to the following URL because I found a way to reset my Battery Use display and GPS & Tool Box disappeared from my Battery Use list because it was no longer running.

Is there a patch planned for the increase in battery use after I upgraded yesterday?

Is there a patch planned for the increase in battery use after I upgraded yesterday? I've closed all the open apps, I'm not using wifi and my battery is going down really quickly.

Restore the phone as NEW. There's no patch needed.

An app to show battery use????

Hi. Recently I have noticed my phone getting rather hot and the battery going down faster than it used to. I haven't really added any apps, but i've noticed alot of apps (mainly googles) have had updates in the last week or so.
Are there any apps that show the phones battery use per app, so i can see which 3rd party apps etc maybe causing the problem.
Cheers

I won't suggest you to use any 3rd party battery savers or anything,they might affect the battery life itself. Use the graph from power management.
All we have to decide is what to do with the time that is given to us - J.R.R. Tolkien

Need to increase battery use time.

Since updating my iPad2 to iOS7 my battery use time is reduced. Are there any alterations that I can make to my settings to maximise my battery use time?

Hi
You should charge and discharge the battery until it would be completely empty.
This should be done always and this helps to calibrate the battery and to increase the battery life time

Battery Big Question Mark Symbol

My pre plus has suddenly developed a battery big question mark symbol. Any advice?
Post relates to: Pre Plus p100ueu (02)

Battery symbol with a question mark indicates no battery present in the device. You can try cleaning the battery contacts with a pencil eraser, or replacing the battery.

Ipod hifi battery use

Bought myself a nice ipod hifi, perfect sound, only one terrible disapointment, batteries of hifi don't charge in the ipod-hifi.
For such a design this is a lack of thinking, it is quite simple to make batteries charge themselves, see all the cell phones.
MacBook Mac OS X (10.4.7)

I honestly don't think Apples intent was for the Hi-Fi to be remarkable via battery use. Due to the weight and size of this unit, its really not a feasible unit for portable use. Sure, you can do it, but I can't see myself lugging this big boy around. I think there are many other solutions that may not provide nearly the sound quality, but will most certainly be lighter and provide much, much better battery useage including rechargeables.
I suppose there are some situations where I could see myself using the Hi-Fi on batteries, but those situations would be far and few between, so buying regular good alkalines would be no big deal. My understanding battery life isn't that good anyway.

High % battery use is "standby" after Lollipop 5.1 on Moto X 2013

Thanks to AT&T for finally pushing out Lollipop to the Moto X 2013, it love it. Except, now the highest user of battery, buy a significant amount, is "cell standby". What is doing this and how can I "fix" it? Cell standby never showed anywhere close to the top of the list of battery use until the upgrade.

Tried all of the ideas that one can actually do; the battery isn't removable on the Moto X, of course. Nothing, including factory reset, solved the problem of high battery usage on Cell Standby.
I was able to have no use of cell standby almost all day today by turning off Location Services. For some unknown reason, in a two hour period this afternoon, in the same location in my office as I had been for the rest of the, even with Location Services off, it burned 14% in cell standby.
This is quite apparently an issue with Android 5.1 that AT&T pushed via OTA update. I understand that AT&T has stopped the OTA updates for the time being. Hopefully, when they resume, this issue will be fixed and they will include us with a patch for the problem, and any other problems that compelled AT&T to stop the push.
Anyone else have any other ideas?

HT1446 Battery use

I have Macbook Pro Retina Display. Should I plug in the wire at all time so that I don't use the battery or should I charge it to 100% then use it to maybe 10% then recharge it again to 100%? Which one is the best way to preserve the battery power? And which one is the best to preserve my battery?

You can leave it plugged in all the time if you want, ...and OFF.
*However if you dont plan on using it for a few hours, turn it OFF (plugged in or otherwise), ...*you dont want it both always plugged in AND in sleep mode
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
Keep it plugged in when near a socket so you keep the charging cycles DOWN on your LiPo (lithium polymer) cells / battery.
*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
You certainly CAN leave your macbook plugged in all the time, take it off charge and drain the battery down to 15 or 20% every couple of weeks or so.
LiPo (lithium polymer, same as in your macbook) batteries do not need conditioning. However...
LiPo batteries do NOT like to be dropped down to 15% or so often,....key word being "often"
A lot of battery experts call the use of LiPo cells the "80% Rule" ....meaning use 80% of the charge or so,.. then recharge them for longer overall life.
Never let your Macbook die from power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to LiPo cells is instances when often the cells are repeatedly drained very low.
Contrary to what some might say, LIPo 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 dont take a new car out and speed and rev the engine hard first 100 or so miles.
*Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.
*Cycle count / use/ lifespan is one thing that cant be countered.
Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.
Just use and enjoy your new macbook,
From Apple on batteries:
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1446
but really all you would keep in mind is --"consider 15-20% is the same as 0% and recharge it"
and best "tip" is if its near a socket, .....plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)"
Important useful info on your Lithium cells as compiled from battery experts:
Heat increases battery performance but shortens life by a factor of two for every 10°C increase above 25–30°C (18°F above 77–86°F). This is yet another important reason for the cooling of any notebook, not just keeping the processor and GPU cool. Mavericks lower power tasking (app nap) and combined with the cool running Haswell processor both greatly protect battery life on your Macbook now more than ever before.
Good news: *Mavericks not only increases a single charge cycle for longer battery use off a full charge,… but also prolongs the overall long term life of the LiPo battery in a Macbook by reducing the load conditions the battery experiences from heavy peak-use.
Counting cycles is not conclusive because a discharge may vary in depth and there are no clearly defined standards of what constitutes a charge cycle on a Lithium Ion battery empirically. Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count.
The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine.
Frequent HIGH depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
Although better performing when warm, lithium polymer batteries live longer when kept cool.
Lithium cells prefer draining conditions at a steady pace rather than fast pulsed or quick discharges, …this fact is idealized now with the Haswell and Mavericks app-nap low power tasking for battery use.

Sensor battery use when inactive

I use a shoe pouch for my sensor. It's quite a tight fit and is laced into my shoe so it's not very easy to remove the sensor if I want to place it into sleep mode.
Is it sufficient for me to solely rely on the automatic inactive mode of the sensor to suspend any use of the battery? My expectation is that ...
1. If my shoes are sitting in a cupboard then the inactive mode will result in zero battery use.
2. If I wear my shoes, but not connected to my iPod, then the sensor will be continually woken up unnecessarily, thus depleting the battery.
Are my assumptions correct - will I need to leave my shoes in the cupboard and only use them when connected with the iPod in order to prolong battery life?

You are not alone. I have had my Nano for several weeks now and have noticed the same thing. I would use it for short trips in the car while I ran errands and find that after only technically using it for maybe an hour or so (over the course of several days), I would already be low on battery. I read the manual and you can only put the ipod in sleep mode. It stays on for 36 hours and only then will it actually turn all the way off. So technically the battery last for several days but that doesn't do you any good unless you are using it for long periods of time all at once. I'm really frustrated because I really like it other than the fact that I'm always having to charge it.

Battery use in settings

i`m not sure if this is even a problem but when i click on settings and try to see what is using up the battery all i ever see is display and cell standby. I use my phone almost non stop. checking these and other forums. facebook. texting and a lot of internet searches and i would assume that the battery usage would reflect all of these programs and not just display and cell standby. If this is the norm than thanks for letting me know but if it isnt then i`m hoping someone could shed some light.

No worries this is normal. With the larger screen that your phone has the more that it will use your battery. The more you begin using the programs the more battery use they will use. Hope this helps

Poor Performance when using Question Pooling

I'm wondering if anyone else out there is experiencing
Captivate running very slow when using question pooling. We have
about 195 questions with some using screenshots in jpeg format.
By viewing the Windows Task Manager, CP is using anywhere
between 130 to 160 K worth of memory. What is going on here? It's
hammering the system pretty hard. It takes a large effort just to
reposition the screenshot or even move a distractor.
I'm running this on a 3.20GHz machine with 3GB of RAM.
Any Captivate Gurus out there care to tackle this one?
Help.

MtnBiker1966,
I have noticed the same problem. I only have 60 slides with
43 questions and the Question Pool appears to be a big drain on
performance. Changing the buttons from Continue to Go to next slide
helped a little, but performance still drags compared to not using
a question pool. I even tried reducing the number of question
pools, but that did not affect the performance any. The search
continues.
