Best long term battery life Should I leave plugged in when I can?"

Hi
If I want to get the best life out of my battery, it would seem to me to get the lowest number of full "load cycles", that I would leave plugged in as much as possible.
Is this logic corrrect?
thanks

Charging to max capacity reduces battery service life. Getting close to max (but never waiting till the plug symbol shows up) will extend your service life.
So if you charge it this way (charge close to, but not full capacity--i.e., plug symbol does not appear)...won't this mean the iPhone's "Usage" meter would never display any figures since IIRC once the iPhone 3G detects that it's receiving power from an external power source (e.g., charger), it resets the Usage stats...at which point the Usage meter will then not display any usage info until/unless the phone is fully charged?
IOW--if you don't charge the iPhone to full capacity, you'd never be able to see how long it's been in use and/or in standby since the Usage meter will start to tick only from a full-charge condition (it even says "Time since last full charge" at the top of the Usage screen).

Long term battery life

Any idea how many cycles the battery can take before being replaced... anti-iPhone types are telling me only 400... anyone know for sure?

I believe that is true. But it's not counted as how many times you hook it up to charge. It's 400 full deplete and recharge cycles.
So, if you charge it when it's halfway down (as an example), that only counts as 1/4 of a charge cycle.
I think if you don't overheat the iPhone by leaving it in a hot car or something, it should last at least until you are ready to upgrade to a newer iPhone (like 2 years or more). I'm well into 2 years with my iPod Video with no signs of the battery going bad.

Long term Battery preservation...

A genius at Apple retail told me this tip for longterm battery life:
don't leave the computer plugged in while it sleeps. It's cool to let the HD spin down and let the screen sleep, but down let the system sleep without pulling the AC.
He also said that when it comes thime t do a weekly calibration, that letting it dry up all the way is sort of a wives tale... In fact, its better he says to let it go down almost to 0 and similarly not to let it get to full capacity on the recharge (this is achieved automatically whenthe AC is in and the system is still awake. Basically the system tricks the battery into not charging all the way which for some reason save it in the long term.
Does any of that make sense, and if so are there any other means by which one can keep the battery lving and lasting longer (short term and long term suggestion welcome, many thanks in advance.

It seems geniuses ain't what they used to be...
1) You can choose to have the disks spun down when attached to external power.
2) I'll take the word of the engineers who designed the device and chose its components over that of an hourly guy in a retail store any day. By that I mean I'll follow Apple's published instructions on maintenance. It's not that they might not discover a better way, but I just consider them a lot more authoritative.
The whole power and battery area seems rife with folklore. Folklore and computers don't mix!.
Take your advice from the horse's mouth. Follow Apple's instructions and recommendations. They publish a great deal of information on-line. I have to believe it's generally well vetted by their engineering staff.

How can i extend the battery life of my iphone 4s? when i left it in standby mode when i saw in 5hours it drains to 5%, i thought when i leave the phone the percent is still the same. whant am i goin to do?

I was not aware of the fact one could use ringtones as alarms, this will suffice! Although I foresee some very awkward times as the sound does not stop once I respond to the reminder (it keeps going for good five - ten seconds after I "stop" the reminder), but it's better than missing it altogether!
Thank you very much!
Regarding the Alarmed app, doesn't it have to be running to actually remind you?
-Modular747: I don't know anyone who actually reads the terms of service agreement, those things are usually up to thirty, small print pages full of legal jargon. Rules, I do read - not the legal documents (also they often contradict the laws in my country, but that's a whole different story).
I agree with you - the average customer support consultant mostly cares about keeping his job and earning his salary (don't we all?) and thus racking up completted tasks (i.e. getting rid of customers as fast as possible - in a good mood). The "threat" none the less is real, if a cell phone causes me more trouble than it is worth, I will indeed throw it away (I have done so before) - and recommend a different brand to anyone willing to listen.
Don't get me wrong, I love Apple and I've been faithfully using and recommending their producs for twenty years now, not because of fanboyism, but because they earned it. This calendar issue, however, is like a toaster that doesn't automatically eject the toast at the set time. I see it as a major flaw and after googling around a bit I see that it's been around since at least 2007 (THAT'S SEVEN YEARS!!) so I strongly believe they are aware of this problem by now, but are choosing to ignore it for some mysterious reason and it really ****** me off.
I will send the feedback but based on my observations I suspect the Send button is merely a cleverly disguised Delete button.

I am staying long term at a hotel. Is there a way I can boost the wifi signal?

I am staying long term at a hotel. Is there a way I can boost the wifi signal?

I think you may have better luck working with the hotel management and have them contact their wireless service provider to see if they can improve the signal in your room.
The only other option might be an external Wi-Fi antenna for your iPad ... but I'm not aware of anyone providing these at this point in time. Sorry!

Does it adversely effect the battery to keep the IPad plugged in when fully charged?

Does it adversely effect the battery to keep the IPad plugged in when fully charged?

Copied from Texas Mac Man ...
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.

Unicode escape sequence - what is its purpose?

Best settings for battery Life?

And away they go! Has anyone experimented with settings for optimal battery life?

Well, you have to decide what you want to use and when. To get the best battery life, you'd turn off everything (phone, WiFi, GPS, Bluetooth), and turn the screen down to the lowest setting. But that eliminates most uses of the phone (calls, email, web, location functions, handsfree).
I've been leaving 3G and BT on, turning off WiFi and GPS until I need them. Searching for WiFi networks can drain power quite a bit (judging from my experience with the 1st gen iPhone), and it seems to me that the location services were sucking power even when I wasn't using them. I haven't confirmed this last theory yet, but my battery does seem to last longer with it off.
I suppose a somewhat less-extreme approach than shutting off everything would be to leave on the phone, but disable 3G (and everything else). This would give you phone calls and (slow) network access, but no location services or handsfree devices. To me, this seems silly - it effectively downgrades your phone to a 1st gen iPhone, unless you don't mind flipping 3G on and off as you need it.

Long Term Battery Storage

Hi! Last week at my local Apple Genius Bar, I was advised to long term store my unused PowerBook battery at a 50% charge (okay, standard advice I know)....the rest of the advice was "stored in the freezer and it didn't need to be protected in storage bag". Has anyone tried this? Does freezing offer more protection than just sitting in a drawer with a 50% charge? I want to prolong my battery as long as possible so all help is very much appreciated.
15" PowerBook Mac OS X (10.4.9)

Sounds like the tech was misinterpreting. According to this source, 40% charge in a refrigerator is good for long-term storage, but freezing is FORBIDDEN.
So 40%-50% charge, cold but NOT frozen.

How long of battery life can you actually get on your U410/U300?

Hi --
I got my U410 Ultrabook today and thus far have been extremely happy. The internet isn't spotty, the touchpad and keyboard work great, and it looks beautiful. The only concern I have is the battery life. Lenovo advertises 8 hours but I expected five or six realistcally.
I started mine up right off the bat and it was at around 80%. I did some hardcore downloading and was using it constantly and it died in maybe 2.5 hours (to be generous). I'm charging it right now and am hoping to get a better result off a full battery.
What's everyone else's actual batery life experience? What are you usually averaging from a full battery? I figure if I turn down the brightness a lot and don't download a lot I can probably max out the performance.
Honestly I'd be happy with five hours on a full charge.

I was the one who reported 5.5 hours of battery.
On the first day, when the battery was dying pretty quickly, I went into Resource Monitor (quickest way to get there is to start Task Manager, go to the Performance tab, and click Resource Monitor at the bottom of that window.)
You can sort that list by the CPU column.
Anyway, I saw Quick Update eating up a large amount of CPU time.... like 25% or more. Quick Update is bloatware, designed to update email and social media in the background. Do people still even use local email clients??? ;-)
After uninstalling Lenovo Quick Update my CPU usage dropped dramatically and battery life went up 2x.
Thanks, battery life has definitely improved after a week now and with brightness settings adjusted and uninstalling Quick Update it's even better.

I'm having major issues with battery life on my iphone 5 . When I'm on 3G my battery on lat 6 hours . But when I'm on edge network I get almost 8 hours usage and full day stand by . That's a. Major difference. But these phones were built for 3G and LTE .

The battery only last 6hrs complete with basic normal usage . I tried all the suggestions and nothing was helping. I finally tried switching off the 3G to EDGE and what a major difference in battery life . My phones last more than a day . I got so far 8 hrs usages And 25 hours standby . But that's phones were created to handle lte and 3 g why is it killing the battery life ?? How can I resolve this issue ?

Thanks for the replies. It took a while not hearing anything so thought I was alone. I have done many of the suggestions already. The key here is that it occurs on both phones with apps, and phones still packaged in a box.
A Genius Bar supervisor also checked his Verizon data usage log and found the same 6 hour incremental use. Suprisingly, he did not express much intrigue over that. Maybe he did, but did not show it.
I think the 6 hour incremental usage is the main issue here. I spoke with Verizon (again) and they confirmed that all they do is log exactly when the phone connected to the tower and used data. The time it records is when the usage started. I also found out that the time recorded is GMT.
What is using data, unsolicited, every 6 hours?
Why does it change?
Why does it only happen on the iPhone 5 series and not the 4?
Since no one from Apple seems to be chiming in on this, and I have not received the promised calls from Apple tech support that the Genius Bar staff said I was suppose to receive, it is starting to feel like something is being swept under the rug.
I woke up the other day with another thought ... What application would use such large amounts of data? Well ... music, video, sound and pictures of course. Well ... what would someone set automatically that is of any use to them? hmmm ... video, pictures, sound. Is the iPhone 5 succeptible to snooping? Can an app be buried in the IOS that automatically turns on video and sound recording, and send it somewhere ... every 6 hours? Chilling. I noted that the smallest data usage is during the night when nothing is going on, then it peaks during the day. The Genius Bar tech and I looked at each other when I drew this sine wave graph on the log print outs during an appointment ...

Updated to OS 10.7.3; fan runs constantly and battery life dropped to under 2 hours when 100% charged. How do I get back to 10.7.2, I don't have a backup prior to this upgrade. This is a newer Macbook Pro 13", no modifications.

Help! This new version of Lion is making me miserable. The fan runs constantly, the computer is hot and battery life has dropped to under 2 hours on a fully charged battery. I updated yesterday, nothing but misery today. Even running the mail program alone make the fan run like I have everything open. Using Pages, iPhoto, and iTunes simultaneously makes the computer blistering hot.Yesterday, I could use all three without any trouble. Any suggestions to either jettison 10.7.3 or how to fix without any expense? I haven't modified this computer at all, it is as it came from the box in August 2011: 2.3 GHz Intel Core i5, 4GB 1333 Mhz DDR3.

I updated to Lion 10.7.3 and started noticing my fans running on high all the time and my battery would drain 2-3x faster. I was going to take my computer into an Apple store until I found this thread. I did the SMC reset by shutting down my computer, plugging it in, and then pushing down shift+control+option while also pushing down the power button. Nothing happens on the screen and the computer did not turn on. I then released all the buttons at once after holding them down for 10 seconds.
After that, I simply turned my computer back on and everything seems to be working fine. The fans are not blasting anymore. I have a newer MacBook Pro where I can't access my batteries. The SMC reset may differ for other types of laptops.

Since the new software up date my battery life is going down very fast. How can i fix this?

Ever since i updated my iphone 4 with the new software. My cell battery life is gone so fast. I dont know how to fix this and wondering if there is any one that can....

There are numerous posts in this forum on how to maximize battery life. Either look in the "More Like This" box to your right or do a forum search.

Hello just got my iPhone 5s but notice the battery life only holds up for 12 hours. Can't be normal?

Hello just got my iPhone s everything went well when I all was connected..but battery life not holding up to at least 48 to 72 hours like I thought it would..doesn't last 24hours! help

That would depend on how you are using your phone.
