Getting good battery life

Hey guys, so I have a new macbook pro 15 inch, and I am wondering if I should do somethign first to it maybe the calibaration to get good batter life? I just charged it all night, and I am in class, and just doing webbrowsing, it is saying that I only have 3 hours left? Not sure why, but that number should be higher right? the brightness is on low and everything.

The time Apple quotes for use on battery power requires that Airport, bluetooth are turned off, no externals are connected, no cd in the drive, etc. As soon as you use these or headphones, mouse, etc your available time will be lessened considerably. Tasks that you have it doing can also affect performance, especially any that involve much reference to the internal drive or heavy processing.
Calibration is primarily to have more accurate stats. It sets the original actual capacity of the battery and enables calculations & comparisons to be more accurate. I'm not sure that it actually improves the life of the battery, rather it enables a more accurate estimate of condition & performance to be given.

My new iPod nano does not get the battery life that is advertised

Help me my iPod nano does not get the battery life that is advertised

Which battery life are you referring to? Apple's website states the iPod Nano 6th Gen will get "up to 24 hours of music playback when fully charged". There are going to be a lot of things that can change that. Are you using the stopwatch or the count down timer a lot? Are you using the FM radio a lot? Any accessories that you are using with the iPod? These will all have an effect on your battery life.

After 4.2.1 Dropped/Choppy calls and poor signal / Gets hot / Battery Life is bad when talking

What is this APPLE? I can see the Iphone 3G is old and no more support but atleast make a working OS and then go out on a high note. Instead of leaving us hanging with a broken phone. Not just me , scores of others have these very same symptoms. Also I wish there was a way to go back to an older OS , one that worked %100 for my phone.
Dropped/Choppy calls
Get REAL warm
Batterylife is crap only when talking
Never had these problems before 4.2.1 , it's like night and day. I was hooked on the Iphone since I bought this 3G brand new and its ease of use but Ill tell you one thing....
Im not under contract right now with anyone
I WILL NOT be buying a phone/contract with APPLE as long as 4.2.1 is left in our "lap".
I WILL be buying another smartphone if this is what we are left with. I was going to treat myself and buy the 5G with a contract to make it cheaper but as of now
Im feeling "used" by APPLE and not going to take it.
I know some might come here and post ..
"Me and others aren't effected by 4.2.1 , must be your phone"
BS! It was night and day when I downloaded/installed 4.2.1. This is NOT my Phone and IS the firmware. And my friend that is a phone nut said he didn't download 4.2.1 because of all the problems he was hearing about it, I should have done research. He said the biggest hit was the 3G and he can't belive I installed it.
APPLE DO YOUR JOB AND FIX THIS. MAKE 4.2.2 ATLEAST AND FIX THESE PROBLEMS!! IF NOT THEN WE MUST PART WAYS.

Cool
Did the new device and didn't do a restore from backup. Grabbed all my contacts from windows contacts saved list. So only thing the same on the phone was the same 4.2.1 that stays in there. Still bad signal and battery life, although the battery problem might be the age of the battery since its the same battery that came with the 3G.
I did the Field Test mode program
http://socialtimes.com/find-your-iphones-signal-strength-using-the-hidden-field- test-mode_b4690
- Open the iPhone’s dialer keypad
- Enter *3001#12345#*
- Press the Call button
-80 to -70 dBm: Reasonably strong signal
-107 to -90 dBm: Weak signal
-113 dBM: No serviceable signal
In my house im getting any were from -100dBm to -117dBm ( 1 to 2 bars with 3G)
Outside Im getting -85dBm and up. (2 to 4 bars with 3G)
I have to do more testing to get solid numbers though. I got almost full bars all the time if I switched to EDGE.
(4 to 5 all the time with EDGE). That makes me think that with the problem in 3G , it's the OS. Since ALOT of people saying that there 3G drops or is bad since 4.2.1.
Now I looked around and I playied with all my settings to insure that my battery should not drain thru improper settings. So I think given this is the original battery , it might be a good time to try and install a new one from here for $17.
http://www.iphonebatteryrepair.com/iPhone-3G-Battery-p/bat-1001.htm
Iv'e opened Iphones before (fixed my friends 3G) after he dropped his and the vibrate/silent button's screw came loose and he could not change it off silent mode and replaced a battery in my other friends 3Gs. SO i feel comfortable in there.
I dont know if the bad battery could be reducing my signal.Ill try the battery cause it's only $17 (Cheap investment) and because my battery life under a load drains it fast. Again I don't know if it's the OS or the age of it.
I was thinking maybe a poor contact/condition of my SIM card could be another possibility. I wonder if and how much a new SIM card from a AT&T provider is. I heard people saying you can get a new one but Ill have to ask my local AT&T dealer.
Although this seemed so odd how it all happened the same night till now RIGHT after the 4.2.1 OS install and all the others people saying the same symptoms.
Ill keep working with it and give you (and others users here) updates in my progress for the people who are in the same "boat" as me.
By the way I haven't tried to make Itunes re download the OS by deleting the file in the directory you gave me above. Ill try that as soon as I post this message.
Also Iv'e noticed that theres a way to download a older version of Firmware OS and put it in a certain directory and use the DFU mode (Deep Firmware Upgrade) on the Iphone to force the Iphone to re install the current version or an older version ( whatever version you download) of firmware. Now Im very worried that this might mess my Iphone up to were it wont even work so I really dont want to try this right now or until I exhaust all my other options. I have to do more research of this method.
Sorry for the long post but I think I kept it faily organized for a easy read, I hope.
                            Thank You Ingo !!

New iPod Nano... How to get best battery life?

Hi there. I just got a new iPod Nano. What is the best way to get the best battery life? I know there is a partial charge on the iPod already (it turns on and the batter meter shows it approx. 2/3 full). Should I plug it in a fully charge it first? Should I put some songs on it and fully drain the battery and then fully charge the battery and then fully drain it again?
How can I get the best battery life out of it? Are there any Apple documents to explain how?
Thanks,
Keith

There are documents, there are theories, there is folklore, there are opinions. I'll give you my opinions (but they are based on a fair amount of research and experience). The type of battery used in the iPod has a useful lifespan of between 3 to 5 years, and can be completely charged/discharged between 300 to 500 times. If you charge it totally, discharge 1/2, charge to full again, and discharge 1/2, this only counts as 1 total discharge, so don't worry about running it all the way down, etc.
You can leave it plugged in all the time if you want, because it's smart enough to stop charging when it's full. You can recharge whenever you want based on what I stated above.
Is there any advantage to running it all the way down and back up? There is an Apple KB document that suggests getting "exercise" like this is good for the battery on a monthly basis. Several people here swear by that, but when I have asked, the only source they usually give is the Apple article, or things based on that article. I've not seen this claim independently stated.
What is true is that you may need to let it run all the way down occasionally to keep the battery meter calibrated, but this has nothing to do with the actual condition or health of the battery.
Also, it's bad to let the battery run all the way down and then remain that way for a long period of time. Plus, if you plan to store this type of battery for an extended period (i.e. for a month or more) then the optimum charge seems to be around 60% of full, although it would gradually trickle down from that over time. Also, don't get it too hot as that's bad for it.
Is that way more than you wanted to know?

How does 2nd generation mini get better battery life?

Hey all
Just wondering basically if the 1st generation ipod mini can have the battery changed or something so as to give it the claimed 18 hour battery life of the 2nd generation rather than just 8 hours

You can measure and compare battery 'life' by looking at the capacity in mAh. As the Mini battery is 400mAh, you can expect somewhat proportional run-time increases as you get higher capacity.
See: http://pdasmart.com/products/AP39ipodpartscentermini.htm as an example. This is the largest that I have seen, but I'm not really looking at this time. Do a Google search for more like this.

I Have been getting BAD battery life after the ICS UPDATE !! on the DROID RAZAR MAXX have this happen to any one else ??????

i have been getting really bad battery life after install ICS on my droid razar maxx i can only go 1 day and 3 hours where i used to be able to go 2 day easy have this happen to anyone else can someone tell me how i can make my battery life better??????/ and do i need to let my phone go complete dead before fully chargeing it again ??????
before install the ICS update i had 30 percent of battery life remaining so i pluged it in and let charged for a little bit while it updated my phone and ever thing after it updated i unplug my phone and started playing on my phone to see what ICS was all about but when it got to 15 and said " connect to your changer so i did !!!!! should i haved let my phone going complete dead since i unplug without it fully changer or does it matter ?????????????? if someone could please help me !!!!:)

What was your battery reading right after the update when you unplugged the phone? I have never let my Maxx drain further than 20% battery ever before I charge it. Yesterday after the update I also played more with the phone trying to learn the OS, as did most everyone on this forum. Give it a few days of your normal use before you decide your battery life has decreased. I took my phone off charger today at noon, it was 100%, and now it's 80%, with about 30 min talk time, and mostly standby. that's about normal batt life for me, maybe a little better than before the update. I'm still going to watch it for a few days before I make a conclusion about battery life.

Getting more battery life with Mighty Mouse

Hi,
is there a way to make the Mighty Mouse read accurately the level of energy left in its batteries?? I have over 20 AA batteries of any kind (rechargeable or not, lithium or not, 1.2v or 1.5v, 2300 mah or else, etc.) and they all read "good-70%" when I test them with a simple battery tester. Still, the Mighty Mouse reads them very low, if not dead. What to do with that??
Thanks.

How interesting. I've been relying on the computer reading as valid. I guess I'll have to get a battery tester myself and check it. You might bring the batteries into a nearby Apple Store and show the techs there what's happening. If you do that, post again with whatever you hear. If I can get the same results, I'll bring the mouse and the batteries into an Apple Store and let them figure it out.

Turn off Wi-Fi, get more battery life

How big of an increase will there be in battery life on the touch if I have the Wi-Fi turned off?
Prof.

You will probably get some improvement, although if you aren't using it then it probably won't be spectacular.
Saw some posts here saying you can get 7 hours of battery using Safari/WiFi.
I get about 2 hours surfing the Discussions.

Why does my iPad 2 get worse battery life with iOS 7???

This new update has way too much white on the screen even when fully dimmed it seems to use more battery than before. Can there be an update to change that?
And in case anybody asks, NO, my battery has been properly taken care of. Charged perfectly each time. So that's not the issue.

Don't know how much the tips in this article http://osxdaily.com/2013/09/19/ios-7-battery-life-fix/ might help but it's worth a look.

Is this good battery life for an iPhone 4?

I have two iPhone 4's. (That's iPhone 4, not 4s! )   I was wondering how well their battery life was holding up.
Over several days of use, I found the following. (These are different usage patterns, after a full charge of the battery.)
iPhone 4 #1
     After 8 hours, the battery was at 34%.
     Another time, after 5 1/2 hours, 56%.
     Yet another, after 10 1/2 hours, 14%.
IPhone 4 #2
    After 7 hours, the battery was at 45%.
    Another time after a full charge, usage was 5 hours and battery 55%.
I used both phones similarly in the 5 usage periods.
Would this be the best way to determine which iPhone's battery is in better shape? (They seem similar.)
Or, is there an app that would provide the equivalent of what the Mac's System Profiler does--telling mAH remaining on the battery and a verbal adjective describing the battery's condition?

haleyfromtoledo wrote:
Is this normal?
I just charged my phone to a full 100%.
Now it is at 96%.
With usage: 13minutes.
And standby: 33 minutes.
The battery drains about 1% for every 4 minutes of use, so that seems normal. But it's too small a sample to be meaningful. You need to go through several discharge cycles and record the results to determine if you are within spec. Alternatively, stop being obsessive about battery life and just enjoy the phone.

What I did to get fantastic battery life on my iPhone 4

I followed loads of advise and tips in this forum and many others but the things that worked best for me was jsut to hard reset my iPhone 4 once after installing ios4.1 and then go into notifications and enable all notifications, especially selecting all three options under the game center and then i waited for a couple of minutes and turned off notifications entirely. I am at about 2 hours of usage, 2 days and 1 hour of standy and with about 45 minutes of talktime, my remaining battery is at 75%. I have 3g,push and all notifications turned off and only turn on 3g when i need to. I used the camera a little including taking a video and surfed around the app store and facebook a little. still at 75% after 2 days of standby? i can hardly complain.

Whether the battery performs to quoted specs is another thing but have any of you guys ever used smartphones by other manufacturers?? Fact remains that you can get a day of heavy use out of the iPhone 4 (if not, yours is faulty) and that's pretty good going! All these people who expect to use their phone for hours, have push on, 3G on, wifi on and then have 99% battery remaining just haven't owned phones by other manufacturers before - I'm sure of it. Your powerful phone has a small battery inside it, this will deplete when you use it. Go figure.
If you're a heavy user and charging your phone once every 24 hours is a problem, that problem is yours and not Apple's. I'm the pickiest person on the planet, you should have seen me over on the HTC forums complaining about just about everything 9 months ago! I'm on my first iPhone, my first iPhone 4, this is the first phone I've not had to send for a replacement and I'm very happy with it. Does it perform to spec? No. Does it have issues? Yes. Is it basically fantastic? Yes. I've never seen so many moaners as I do on these forums! I thought I was bad!!

Will the iPod touch every get a battery life percent gage

I was wounding if the iPod 5 will ever get the power percent gage

See:

However. % battery on an iPod is not accurate. The % battery shows large fluctuations

Good battery life

my iphone battery when fully charged last 1 full day and 3/4 of new day with avg usage (some phone calls, alot of txt, internet usage and video watching. I have 3G on, but i got push off, GPS off, BT off and wifi off. is this consider good, avg, or bad battery usage ?

Hi purplehaz20,
I don't think there's a problem with your iPhone. I would consider it between good and average battery usage.
You have to consider that 3G uses a lot of battery, and as you told you use it also to watch videos and text a lot, then I think it's pretty good to handle almost 2 days long!
Best Regards!

Anyone getting GOOD battery performance on 4S?

There are lots of threads on poor performance and what to do about it... but is anyone getting performance that is close to the specifications that Apple advertises?
200hrs standby and some calls/web could equal a charge every few days. Who can go Monday morning to Thursday Morning without a charge and still use thir phone normally?

I think that is impssible. I can go nearly two days with one charge on my 4S but I only make one or two calls a day and use data more than anything.
I have had every iPhone since the original and the longest I could go was two days and that was with no use.

E90 gets warm (battery life)

Since i purchased E90 i had some strange issues with phone,sometimes battery stays for 2 days and sometimes for 2 hours...
I dont know what can be the problem E90 becomes hot and battery dies....Any ideas what can be the problem? I already formatted the phone
nokia 8210->3310->3330->8890->6800->3220->6680->n72->E-90->5310XM->5610Xm->n82->n95 8gb->5800XM 8gb->2630

Take it to a nokia care point.. sounds like a faulty phone or battery or even both!
