Another weird battery issue.

I downloaded a battery power management tool that said that my mac was 20 months old and that the max for the battery was 4400 and my max was 4100. Anyway, the battery is fine, but when charging it goes fast to get to 85% or so, then the remaining 15% is about 45 min to an hour to charge. Any ideas as to why? Would this be related to why my battery loses a lot of power while sleeping?

The charge slows so the battery won't be overcharged. It will slow to a trickle when it reaches about 96% and at times will stop before 100% for the same reason. Here's a page with a lot of info and links about batteries and maintaining them.

How much power are you losing while the computer sleeps and over what period of time?

A new iOS update and another new battery issue on the iPhone 5

Has anyone else contacted Apple support and been given te same old "solutions" on the battery issues?
1) Turn off location services.
2) Turn off background app updates.
3) Restore as a new device.
These solutions turn a smartphone into a dumb-phone. I love my iPhone but with every new iOS update, the battery becomes incredibly unreliable. Has anyone found a solution that does not kill the iPhone's functionality?

You can try a soft-reset of pressing and holding both the home and sleep buttons for 10 to 15 seconds so that it reboots, but you are likely to get the same screen. If it does then it will need to be connected to a computer's iTunes so that it can be reset back to factory defaults - do you have a friend with a computer with iTunes installed on it, or is there an Apple store nearby that you could try going to (if there is then preferably make a Genius Bar appointment at it, or don't go at a busy time) ?
Has she been backing up to the cloud ? If she has then she should be able to restore to that. If not then what she can redownload for free from the stores will show in the Purchased tabs in the store apps.

Wicked Weird Battery Issue

Hey,
Over the past few days I have been having a very strange issue.
Here is how it unfolds-
1. Black MacBook goes in for repair
2. New logic board and heatsink
3. Get it back and there is an X in the battery icon
4. Fiddle around with the battery and it is fine
5. X again
6. When I hold the battery a certain way before I lock it in, the cpu recongnizes it.
7. Once I lock it in the cpu doesn't see a battery.
8. The battery doesn't sit flush with the bottom, trust me I have tried at least 50 times to get it to, but it refuses to be flush.
Therefore I only lock it about 3/4 of the way, and most of the time it will see the battery, but other times, it won't.
Should I send this back in, or live with it. Any suggestions?

Try to reseated that battery properly before you turn on anything, after that, try to turn on your macbook when it is in steady position. and do "calibrate battery" when you manage to get it on.
IF problem persist, show your problem to apple store,probably they not properly assembled your battery space, and it kind of loose and won't attached properly between battery and metal plate on the macbook.
Good Luck

Weird battery issue. Any help?

Here's one some of you may have not seen. Or you have.
So my iBook totally died on me one day (CPU and Hard Drive). I was within the warranty so I sent it back, got it all fixed, and it came back to me. However, it came back with a letter saying my battery was not up to snuff. What I think they did was discharge it, because the computer would shut off if I unplugged it. Well, for about two months I just left the crappy battery in the iBook for balance and overall weight distribution. In that two months, the charge went from a constant ~98% to maxing out at around 85% or so. I finally bought a new battery, and went I went to fully charge it, the computer wouldn't display a charge over 85%, and my battery life reflected that. A month later, my battery won't charge above 66% and my BRAND NEW battery only lasts 2 hours.
Now, I'm sending my replacement battery back for a new one, but I can't help but think this is an issue with my iBook, since my new battery charged to the exact same percent as my old battery left off. I tried resetting the PMU more than once, and did the standard calibration when I first got the battery. Nothing seems to work. Is there some kind of system memory?
Thanks for any help

If the router used as an expander of the original network
has its own name and configuration, see if you can choose
it so the original source is ignored. It may not want to do this
automatically; and in some cases, it may not work at all.
Does your configuration panel for networks give you an
option to choose AirPort to be in the top of the list? Is it?
You may have to be sure the correct wireless base is
chosen and see if that setup can be adjusted to allow
the iBook better access or power for the alleged range.
Does the network you have set up give the computers a
specific 195.xxx series of IP addresses behind the router
or other different identities? Since my setup is using the
10.xx.xx sequence, and I have Apple gear, it is a little easier
to set them up to include using the Express as a repeater.
Hopefully someone with general setup experience chimes in...
Good luck & happy computing!

Weird battery issue

Hello here,
I have an iBook 12" G4 @1.2GHz which is around 2.5 years old. Now, it's about 2 weeks that the battery doesn't charge more than 44%, I tried to discharge it completely then recharge it but to luck, it keeps stopping charging at 44%. Any idea?
Thank you for any suggestion or advice in advance.
Best,
Fabrizio

Probably the best thing to do is to go to:

This will give you all kinds of information and links that I think will answer your question better than I could attempt to explain it.

Yet another 920 battery issue; detailed mini-test

I have been having trouble with my 920 battery, but I waited the two weeks for the battery to "condition" assuming there really is such a thing. And, now my son received his 920, and he is complaining about his horrible battery life, too. So, I decided to do a test last night while driving home, and this morning when the phone was fully charged & not used. Former about the recharge speed while driving, and latter about idle discharge.
**** This morning:
7:28am: Phone is unplugged off the wall, at 100%. LTE, NFC, Bluetooth enabled, but no NFC or BT connections made. Email set to "As Items Arrive". Nothing running in the background as verified by holding down the BACK button; only the START screen. The "background tasks allowed" apps are basically the defaults, including NokiaDrive; but none of them are actually shown as "running" when you hold the BACK button.
8:30am: 92%. During the last hour, the phone has not even been switched on, so even the screen hadn't come on. 8% loss in 1hr?! Only a few emails had arrived, but not looked at.
9:19am: 81%. Again, no use of the phone in the meantime. It has just been lying on the countertop. No phone/data features used except those used by the phone in the background. Almost 20% off in 2hrs!!
Basically, with the default features of the phone, after two weeks of "battery conditioning", while sitting on the countertop, starting from a 100% charge, not being used for anything actively, my phone seems to drain at 10%/hr.
In the meantime, my iPhone4 went from 100% to 100%.
**** Last night:
I was driving home for about 30min. Before plugging the 920 into my 1amp USB car charger, it was at 57%. At the end of my drive, it was at 59%. That is 4%/hr recharge rate while the phone is using 10%/hr!
**** Also:
Only anecdotally: It seems because of the difference between recharge/discharge speeds, when I use NokiaDrive while my 920 is plugged into the car charger, I still arrive at my destination with a *significant* battery loss. There were days when I left home at 100%, drove for 30-40mins, and arrived at 57%. Totally unacceptable.
**** NOKIA: Given all the complaints on the web & here on your own boards, I think it is time for you to announce something publicly, not just as a post here, but as a News article & email to all your registered users. Otherwise, you'll see many people switching away from your flagship phone. This is not just a few people running into the problem because they are doing this or that.
Using Nokia 920 running on Windows Phone 8

Worth reporting: After the phone drained by itself very quickly yesterday, I charged it again on the wall to 100%. It actually charged somewhat quickly. I don't have numbers, but it "felt" like 4hrs to full charge.
This morning, over the first hour off the wall, under the same conditions as before (LTE, BT, NFC all turned on, no background apps running), even with slightly more phone/data usage than yesterday, the drain was only 1%. It went from 100% to 99% in one hour, even though I drove around with it in the car, not on a charger, thus moved from cell tower to cell tower, from WiFi to WiFi, receiving & responding to email & text, none of which was happening yesterday. In other words, it performed about 10 times better this morning after full drain & recharge, even in the face of slightly increased usage.
So, maybe there really is something to recalibrating the li-ion battery by draining it fully and charging it up again. Talking to my son last night, he also said that after his phone drained fully a few times, not on purpose btw, it is behaving better now.
Of course, why Nokia would ship these phones with less than optimally calibrated batteries is beyond me. It feels like that is something that should be done at the factory, before the phone enters the box and gets to the consumer, as opposed to being part of the user's initial out-of-the-box experience.

Black MacBook Battery - weird battery issue

I have read the posts about a battery that is asleep and have tried all the fixes but still no resolution. Charger shows green light never show charging. Any ideas as to how to get my battery to take a charge? Thanks in advance !!!

I've had good luck with 3rd party batteries. I've gotten 4 of them off of eBay.

Another weird media issue - red frames at the end of h.264

Tested with CS6 and CC, bunch of media exported using h.264 wrapped in MOV or MP4, this media plays fine in QT player, Windows Media Player, Media Composer, Sorenson Squezze, CatDV, Flame, Smoke, and any other app I try, but in any CC or CS6 app, the last frame is a red frame, which also takes time to show up if you park right in that frame, and some times crashed the app.
Something else is while any other app not from Adobe reports movies to have for example 300 frames, Adobe apps will report to have 301... I can repeat this on any machine I test.
Can provide a movie for testing too.
V.

here is:
https://www.yousendit.com/download/bWJyS3hjNDJUMFBFdzhUQw
open it with QT player and switch it to show you frames not time, you will see it says 60 frames (0 to 59) and there is no red frame, open it with any CC or CS6 app and you will see 61 frames, last one red. This is not very noticeable in Premiere Pro CC when playing, but if you park on the last frame you will see it, After Effects gets pretty slow and not responding for a few seconds when you park on the last frame.

Yet another (different?) battery issue

I have two batteries for my Powerbook, one I keep as a spare and which has only been used about half a dozen times.
Over recent months I have noticed that the original battery (and the unused one) seemed to take an increasingly long amount of time to recharge, but in the past few days it won't seem to recharge at all. The percentage of remaining charge on both batteries will only go down, with one currently at 25% and the other at 37% and no matter which battery I have installed, whenever I click on the battery menu, in the first line it says "10:00 until full"
I've tried all the suggestions that I've seen in responses to other battery issues, including resetting the PRAM both with the four key shortcut and using open firmware and reset-nvram and reset-all. I've also tried resetting the PMU by holding down the power key, until the long bleep and I've just tried the Powerbook G4 Battery Updater, but with both batteries I get the following message "Your battery was not updated. Make sure you have a battery properly installed and then try to update your battery again. Be sure to complete the update process for this battery before starting the update of another battery"
The information in the system profiler for each battery is as follows:
Original battery -
Charge Information:
Charge remaining (mAh): 861
Charging: Yes
Full charge capacity (mAh): 3508
Health Information:
Cycle count: 110
Battery Installed: Yes
Amperage (mA): 10
Voltage (mV): 11320
Relatively new battery -
Charge Information:
Charge remaining (mAh): 1621
Charging: Yes
Full charge capacity (mAh): 4381
Health Information:
Cycle count: 3
Battery Installed: Yes
Amperage (mA): 10
Voltage (mV): 11331
I notice there is a massive difference in the "Cycle Count" for the two batteries (110 and 3) although I haven't got a clue what this means.
Any advice or suggestions would be most welcome, as at present I am worried that eventually I will have run both batteries down and there will be no point in me purchasing a new one if my laptop cannot charge it for some reason.
As ever my utmost thanks in advance to anyone who takes the trouble to get back to me
Kind Regards
Bernard
PS. the charger info in System Profiler is as follows
AC Charger Information:
AC Charger (Watts): 50
Connected: Yes
Charging: Yes

Thanks a million for getting back to me Louie
The ring on the power socket is orange, suggesting that it is charging. However I didn't noticed the 50watts in my System Profiler details for the AC Charger. My Power Supply says that it is a 65w one with the correct model no. for this Powerbook (I think it says A1021 on it but I don't trust my eyesight at this time of night)
Both batteries do appear to be charging but incredibly slowly. For example I have been trying to charge up the battery all week and I had it up to 33% at one stage, before I neglected to plug the power chord in when I turned it on and it slipped back down to 22%. Three days later with it plugged into the power constantly (with me using the computer only during the day and putting it to sleep at night - should it charge when in sleep mode?), it's only crept back up to 30% again.
This battery could be knackered but I hardly have used my spare battery and even that won't seem to charge any quicker
I am also pretty certain that this incredibly slow charging is a recent problem, as I've had that power supply for some time (a year maybe) and I am sure that in the past the batteries have charged up at a more normal rate.
My power supply socket got a little knock recently when I tripped over the cable (as seems to be a common problem on the old non-magnetic sockets) and since then, with the connection not being nearly so snug, it happens quite frequently that I wake the computer from sleep and only realise that the plug is slightly out of the socket when the warning comes up that the laptop will put itself to sleep because the battery is low.
As a result, where previously I was always using the power supply with the battery fully charged and the light on the ring usually green, these days it seems to be permanently orange because I keep running the battery down and in recent weeks it will not seem to charge up because it takes so much time
I am guessing that I must've bought a moody power supply (I guess cheap is cheap, as they say) but I don't think it's the source of my problem because the issue has only manifested itself recently
Many thanks as always for taking the trouble to get back to me
Best Regards
Bernard

Weird battery measurement issue. [Lumia 920]

Hello,
So a few hours ago I noticed that the battery was 9% (seemed pretty normal, since I recharged it only 2 days ago)
I decided to play a game or two to push the battery to it's limit to fully recharge it again.
Okay, afer an hour or so the screen went off and said "Goodbye". Seemed pretty straight forward, but I wanted to boot him up again just to check if everything of the battery was gone. I started it, and what do I see? 48% battery left. I thought it was some mistake to I played a game again for 30 minutes and noticed that it went down to 46%.
It looks like my phone thought the battery was dead while it still had half of it's power over?
First time I try to reboot after it shuting itself down cause of battery, so I can't say that this happend before (yet).
Any idea what happened?

Another battery issue thread

hello heres my **bleep** battery story.
On 11/13/12 at 7pm I received my cyan lumia 920.The battery came with about 30% battery life and i played around with it for a little bit and put it on the charger. At 7am i removed the phone from the charger and went to work. between 7am to 12 pm
-I checked my email 3 times
-made 3 phone calls ranging from 3-8 minutes
-sent 3 texted messages
-checked twitter for maybe 5 minutes
-took 1 picture
-was on this forum reading some posts for about 10 minutes
and my battery dropped down to 52% from 100%
i called Nokia regarding this and i was on the phone with a rep and that phone call last 6 minutes and my battery went from 52% to 39%.By 1pm i had about 15% left. i called att about getting a replacentment and my battery dropped to 9% after 4 minutes.( if i return my phone to an att store i cant get a cyan. i have to mail it in and be without a phone for 2-3 weeks)
is this normal for thsi phone? did i just buy a phone with a sub par day time camera and a battery that wont last a few hours?
I have
-2 emails emails set to sync every hour
-battery saver on
-wifi off
-bluetooth off
-1 app running in the background (battery level app)
-tap to send off
-location on
-kids corner off
-brightness auto
-find my phone off
-feedback off
-high sensitivity off

Hi Joeynox and Sam87,
I too had battery issues with my new 920 when I received it, however after about two or three days and a couple of battery charge cycles, it stabilised and "broke itself in". I now get about 12 hours usage and still having 35% left after making 20 or so text messages, 2 two minute phone calls, ten minutes of Angry Birds, 15 minutes of browsing the internet, and listening to music on the phone all day, with the phone not being in flight mode.
If you are still having problems after a couple more days, i would suggest performing a hard reset, then if that doesn't work, to take your phone back to your point of purchase at AT&T. We have had numerous complaints and they seem to affect AT&T models of the 920, may have something to do with the AT&T applications installed on it causing conflict.
Also turn off your NFC through tap+send in the Settings, that may help....

Just Another N97 Major Issue ..

Here's Another issue in the Awesome N97 ... I left it recording a Video for like 22 min , then I pressed Stop .. It then
said " Processing " .. then .... TADAAA .. Nothing .. came back to camera View .. No Captured Video was there or even processed
Lovely Phone :/
Lens Scratch - Freeze After Phone Calls - SLOW - Self Restart -5MP Camera is Nowhere Near the Sonyericsson 3.2 Awesome camera -Vibrating issues - Mass Storage issues - & the list Goes On & On ..
This Device Does EVERYTHING that you dont want it to do for 620 $
I WILL NEVER GET 1 INCH close to a Nokia Device .
Thank You for wasting my Time & Money .
N97 .. Working or Not , it's still a *bleeing* Rip OFF .

I wouldn't recommend the N97 to anyone because it doesn't do what it says it does on the tin. It's the worse phone I have ever had and I've gone and tied myself in a 2 your contract so I better learn to live with it.
My handset constantly crashes (I would say a few times a week) it can be when a call is coming through to my phone. The only way to get it working again is to switch it off and reseat the battery. On a couple of ocassions it hasn't come back on and I've had to leave it and retry it and eventually I've been able to switch it back on.
My phone crashed this week and I got some sort of memory error (yes on a device that has 32GB internal memory and I have a 16GB memory card). I went into the file manager and noticed that the phone memory was low. I managed between clearing memory errors to get into some settings and changed the save location to mass memory and memory card.
Prior to the crashing I had a problem with the phone not holding the charge, luckily when I took it back to the Phone4U shop the assistant tested the charger on another N97 had the same problem so swapped the faulty charger for a new one.
Another weird thing my N97 does is that although I have a default ring tone set the phone intermittently rings with a different tone.
The BBC iPlayer doesn't work, well that's not strictly true I can get to it but every single TV show I try to view comes up with "Sorry, but to play to BBC iPlayer programmes you need to switch to a WIFI connection". So I exit BBC iPlayer and connect to the WIFI and then go back into BBC iPlayer and it still comes up with the same WIFI message.
Oh and yes I recently updated the firmware... and guess what it didn't make a blind bit of difference.
Nokia I challenge you to sort my N97 within the next 2 weeks and if not you provide me with a phone up to the same value from your Nokia store.

HP DV9000 Laptop Instant Shutdown Battery Issue

Hello everyone,
I'm new here and I am having some laptop issues and was hoping someone might be able to assist me with them. First I would like to list my computer specs:
HP DV9543CL laptop
Intel Core 2 Duo T7300 2GHZ
2x 160 GB SATA HDs
2 GB RAM
Running: Windows 7 x64
Below is a rundown of what is happening and what I have done to try and resolve my issue:
My laptop was making some retched loud noises from the fan and it wouldn’t stop or slow down at all, it would just stay on with its highest RPMs. With my warranty expired, I decided I would open up my laptop to try and clean out the fan and heatsink. I have worked on and built my own desktops for a while and I decided that I should be able to clean the laptop fan (a decision I currently regret). I got everything open and took everything apart and cleaned out the fan and as I was putting the laptop together I had a hard time putting in the flat cable for the HP Quickplay Switch Board and slightly damaged it. After everything was put back together, I fired up the computer and everything booted up properly. I noticed that the HP Quickplay buttons lights still came on, but the volume slider lights were no longer illuminated. The Quickplay buttons no longer work (which I can deal with because they illuminate properly) but I am having a bigger issue now.
I noticed when I booted up Windows, my battery icon showed that my battery was charging but when I hovered over the icon it said my battery had 0% but was plugged in and charging, however the percentage would never increase indicating it was actually charging. I thought this was weird so I decided to unplug the laptop from the AC adapter to see what would happen. When I did this, the computer stayed on but still told me that the battery had 0%. I decided to leave it that way (since I knew the battery had an almost complete charge) and check to make sure everything else worked. After about 5 minutes or so, my computer shut down instantaneously (like if you were to pull the plug without the battery in.) Knowing this was a bad sign, I decided to try and figure out what was going on. I tried plugging in the computer with the battery in and after about 10 minutes or so the computer shut down the same way. Next I thought I would try using the laptop without the battery in and use it on just AC power. This seemed to work and since I have been using the laptop this way, it has been running alright. My wife has the same exact laptop so I thought I would check my battery in her computer and her battery in mine because her computer is running fine, and, of course, her battery does the same thing in my computer and my battery reads just fine in her computer. So I am now resorting to working on my laptop only on AC power, but I’m sure you can understand my frustration in using a laptop this way. I also thought maybe it was a software issue in my Windows OS so I loaded up a Ubuntu live boot environment and found that Ubuntu was reporting the same battery issues as Windows (saying the battery was charging at 0% but not increasing in charge and reporting that the battery was empty when off of AC power but still running for a short time.)
There is one other issue that is happening. If I leave the computer on with the battery in (with or without AC power) and leave it sitting, eventually the battery charging indicator light starts flashing as if something is wrong. This also happened when I had the computer completely off but left the AC adapter plugged in with the battery in (as if to charge the battery). This led me to believe that the issue is a hardware issue but I had to check to make sure it wasn’t an OS problem as well.
I really have no idea what I could have done to the computer to have this happen. I checked everything that I did when disassembling the computer and I didn’t tinker with the battery or anything that controls it, to my knowledge. If anyone has any ideas or suggestions it would be greatly appreciated. I really regret ever opening up my laptop but now that it’s in the past, I’m hoping I may be able to at least fix what I’ve messed up.
Sorry for such a long post and thank you, in advance, for helping me with my issue. Let me know if there is any other information you may need to assist. Thank you for your time.

So I just had another shutdown but this time it was without the battery in and on AC power (which was working fine before). I decided I would load up World of Warcraft to play, since I thought it was working, and after about 5 or 10 minutes of playing the computer shut down. It doesn't restart when these shutdowns happen it just goes off and stays off. I have been monitoring temperatures to see if that could be a potential issue of overheating (although I still think there is a battery problem too) and found that just random web browsing has the computer idle around 44-45 C and when I am running World of Warcraft it was ~80 C. I don't know what normal laptop temps are but it didn't seem overly stressing but I don't know. It's working for normal web browsing and word processing but World of Warcraft is too stressing apparently. Any insight anyone has on this issue would be wonderful. Thanks for your time.
