Again: The Life of the Battery
Hi, I've read a lot of messages with this problem, but, i can't still understand how difficult is to make our batteries have at least more than 2 hours life, using all the resources this kind of computer give us.
I follow all the steps to make it better, all of them, but still my battery has 2hours life. Charging about 4hours or more.
Of couse I use the MBP with all I have to work: web, airport on, bluetooth on, various applications, but I think, most of the people does. So, shouldn't a machine like this deserves a better battery????
Thanks all
Sorry, I'm a little disapointed with THE BATTERY!
It's a simple proposition really; more work a processor can do the more energy it takes. All that heat that people complain about has to come from some energy source and that's the battery. There's a price to be paid for using screaming Intel chips and this is one of them.
I'm getting about three and a half hours out of my MBP running a 2.16 GHz processor. That's optimized for battery life. I suspect that it'll average out to be about two hours forty-five minutes to three hours. My two year old iBook does about that now, averaging just about three hours. Not exciting, but not all that bad either. I honestly don't know how they do it considering how much energy these Intel processors need.
All things considered, the MBP battery lasts longer than my Sony Vaio ever did, and longer than every Dell notebook I've had the occasion of using. Newer Dell machines seem to be on par, however.
The advice of others is good. Turn-off bluetooth, and if you're not using the Airport card, turn that off too. Set up your use while on battery for maximum energy savings. If you're concerned about watching movies on a trip, rip the DVDs to hard disk instead of playing them from the superdrive. Every little-bit helps.

What is the problem with my ipod? what can I do to solve it, I even restored it once
Sounds like the battery is dead. Bu try the following to rule out a software problem:
- Reset the iPOd
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory defaults/new iPod.
If still problem your battery is very likely dead. An appointment at the Genius Bar of an Apple store is in order. -
Is this a sign the battery is on the way out?
I got this laptop about two and a half months ago as a refurb. Apart from some dodgy RAM that I replaced it's been a great laptop. Only thing I noticed at first was the battery didn't seem to last very long. I seem to recall reading the specs that from new the battery was rated at 5 hours? I can charge the battery up fully and it'll say in the menu that it has around 4 & half hours of time, but just sitting there surfing the net seems to zap the juice away.
I think that maximum I've only ever managed to get two and a half hours out of it, maximum and that's just surfing the net, not doing anything else. However, today I was just sitting there surfing the net again, the battery was running down as usual since I hadn't charged it since the night before but it must have had at least an hour left in it. I didn't get a warning, the battery indicator in the menu wasn't displaying red. Then all of a sudden, while I was in the middle of reading something interesting, the screen turned off, then after about ten or so seconds the light on the front turned off indicating the whole thing had shutdown.
I tried to turn it back on but it wouldn't let me. I flipped it upside down and pressed the button on the battery and the first LED flickered as if the battery was empty?
I have tried to recondition the battery by emptying it completely then leaving it on charge overnight but it didn't seem to make any difference. Should I be looking to get a new battery? If they weren't so expensive I'd get a new one anyway.I'm not so sure you have a problem. You seem to be saying you get 2+ hours to a charge? And it charges fine? This is not unusual, and your System Profiler specs look fine for battery capacity and cycle count.
The battery life quote of 5 hours is an advertising figure under atypical conditions - minimum backlight, reduced processor performance setting, no wireless wifi or Bluetooth, harddisk sleep when possible, etc. 2 hours under normal conditions seems about right to me.
The sudden shutdown without warning can happen when a battery is older and drops voltage faster than usual, or isn't calibrated. Try following the Apple battery calibration procedure:
http://docs.info.apple.com/article.html?artnum=86284
Sometimes resetting the PMU (power management unit) and/or PRAM helps:
http://docs.info.apple.com/article.html?artnum=14449
http://docs.info.apple.com/article.html?artnum=2238
Resetting won't magically give you twice the battery life under typical use, but might help with the shutdown warnings and life estimate readings. -
My iPod touch 4G will not charge. I charged it and when I got it off charge it was really hot but showed it was fully charge then when I turned it on again the battery was dead. Now it won't charge. Please help thanks!
Try the standard fixes to rule out a software problem:
- Reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod
if still problem that indicates a hardware problem and an appointment at the genius Bar of an Apple store is in order.
I suspect you have a hardware problem. -
Ibook G4 overheating: not because of the battery, so why?
Hi everybody,
I left my iBook G4 last night on my desk: it was shut down and NOT connected to the power supply, but with its battery in and charged. I found it some 12 hours later very hot and not starting at all (no chime, nothing). I checked it was not already running with a dark screen and it was not. They were no peripherical device connected. I took off the battery: il was cold. The main areas where the iBook overheated during the night were the hard disk (despite the fact it was not spinning) and below the display, in that area where the Airport Extreme Card is installed.
I removed the Airport Card and checked below (Suppl. RAM slot) for signs and smell of something burned. There was none to be found.
Once cooled down to room temperature, the iBook resumed services just as if nothing had happened.
Any clue on what could have happened or hints to what I should be aware of?
Thanks,
Fred
PS: my iBook was eligible to the battery replacement programm and I did replace the battery. I checked again today, and the correct one is in. And, again, the battery temperature was normal, while the frame was very hot.
Message was edited by: Fred FreedI have an iBook 1.33 taken apart here for resoldering. I found one of the two bolts that hold the heat sink to the CPU had broken loose.
Also check to see if your vent grill is clear and freeflowing.
You should feel heat coming from there.

I usually charge my iPad after all the battery drains out but someone told me it damage the software so I wanna know if draining out the full battery is good or not. Thank you.
Lithium based batteries as in the iPad do not respond well to repeated draining.

I dropped my iphone 5 in the water, its dead and when I try to charge it the apple logo comes and goes, thats my only sign of life, I've done many after market repairs but what I want to know is if I should replace the ligntning port or the battery... or just buy a galaxy s5?
If you dropped it in water, and then plugged it in, you may very well have destroyed the battery and/or the logic board. Charging/plugging in to a power source is very damaging to wet electronic devices. There is not much you can do but replace the entire iPhone...and since you did repairs yourself Apple will not do an out-of-warranty replacement.
You can try replacing the battery, the lightning port is another issue, but I would not expect that iPhone to work again. -
''Well When i plug in my ipod touch the battery life is low..i let it sit a wyhle.And it starts up to the apple logo and it stay there some time then it restartsback over to the very low battery and repeat(Over&Over)
Can you reset the device by holding the sleep and home button until the Apple logo comes back again?
If this does not work, try to connect in recovery mode, explained here: iOS: Unable to restore -
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...

Can someone explain what Apple did to remedy the battery life in version 1?
My original post got deleted...i guess it violated the TOS for "ranting" and "speculation".
Yes, the 3g iPhone is an amazing piece of technology with MANY features....but I simply cannot use them and expect it to be a dependable functional telephone at the same time. For years, I have had phones that remain on standby possibly for days, make lots of calls, do lots of texting, browse the net...etc...you get the point.
I purchased the iphone for the push feature, the 3G feature, the wifi feature and the ability to use it as a telephone ......dependably. I work on-call and need to have a phone on at all times day or night. I charge my phones overnight but still have NEVER had a phone lose a charge as quickly as the iPhone does.
Apple's solution right now is to turn off all the features that make the phone so attractive in the first place.
I suspect that I am like a lot of others in that I did not buy this PHONE (yes, it is a phone after all and should have adequate battery life to serve as a phone) to selectively and actively take the time in between calling, browsing, etc. to remember to turn wifi on and off, turn my 3G network on and off and then manually push email. This kind of defeats the purpose.
Is there something Apple can do to remedy this situation via software updates or are some of has hoping for a pipe dream that simply will/cannot happen? I know with the first iPhone there were updates that dealt with battery life. Does anybody know what the formaer updates did physically? I hope something can be done with the 3g version, because right now it is not usable and may need to be returned.
Any software/hardware engineer types out there who can advise if this is indeed a fixable thing or should I return the phone? I REALLY REALLY REALLY want to keep this thing, but as it is now, it is totally not usable for me.
Thanks for reading. . . .hope there is a solution!
(hope this isn't "too speculative" to be tossed again for violating the TOS)
Message was edited by: Woostiwa2I suspect this is your first 3G phone and if so, this is a common problem with all 3G phones and a big complaint. Other 3G phones have a swappable battery which having is a requirement. Since the iPhone does not have a swappable battery, an extra wall charger or keeping the wall charger handy is required. Or having a computer nearby with a USB port along with having a vehicle charger.
If you aren't interested in turning off available features to conserve battery when needed or wanted, and you use your iPhone regulary for web and email account access via 3G, the battery won't last the day - which is the same for any 3G smart phone. With no swappable battery, if the other alternatives are not acceptable, you should return it. -
My question is which better to use every time my iPad until the battery is 0% then charge it to 100% then use it again until it is 0% or i use it until the percentage is low then charge it until it is 70 - 80 % percentage then use it but not let it charge until it is 100% to reduce the number of circles and increase the life of battery as i read that it must at least one time a month use the device until the battery drain to 0% then charge it again to 100% but i don't understand is it must be one, two, three times a month or properly most of the times to reduce the the number of circles and increase the life of the battery?
wuzradioman,
I was originally on your side in the discussion of batteries, however, after being contradicted by Meg St._Clair and others I took a leap of faith and took their advice with my Apple devices. Much to my chagrin their advice has proven true.
Long story short I have not noticed any differences in my battery life by changing my charging habits to what is convienant over what is more in line with conventional battery myths. -
What's with the battery life on this thing?
Okay...I've had my Mini for 18 months. Just yesterday...I charged it at work. Work day ends. I pop in the ear buds...turn it on (fully charged)...and the "low battery" message immediately flashes. I look at the battery "meter" and right before my eyes it goes from "full"...to "empty".
Then the thing shuts off! Tried it again today...and after several repeats...I finally got the thing to play (so far two songs...we'll see).
I can deal with the limited battery life...but the NO battery life thing...well...that's a problem.
Anybody else have this problem?...hear about this?...is there a battery/program flaw in the Mini?See if these links helpS:

I have upgraded my iPod touch and it didnt respond to the upgrade. Cant remember which iOS i was upgrading but when i try to switch it on the apple logo comes up but than it just goes to the loading logo until the battery life is gone. I have tried restarting it , that doesnt work. I need help i am lost without my ipod please help. Any ideas besides restarting it ?
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Hi,
I asssume it's a laptop!
1st I would run it right down & then do a full recharge, then run it down again + a full recharge..
Check that you do not have any apps running in the background, reset PRAM..
When all's done I usually run a movie & time how long the battery lasts..if after that & no joy call Apple Help.. -
