T500 battery life and extra battery

Hi,
I recently ordered and started using a T500 with P8600 processor and 9-cell battery (the one sticking out in the back). After adding 2GB extra memory and an Intel x25-m g2 SSD, I started using it with Windows 7. I have been using it for a little more than a week now, and I've noticed that battery life seems quite bad. Granted, I've only run it on battery for a longer period once, and then I got about 3h 10 min running time on battery. This was with graphics switched to intel, optical drive turned off, wlan and 3g-card off, screen dimmed to half, power plan set to power source optimized.Usage was fairly light, editing code inside Visual Studio.
Would this be expected running time? It seems quite short to me, considering my old HP nc8430 with T7200 processor (34W TDP) and 7200rpm disk got nearly 5 hours when it was new..
Is there any kind of extended battery available?

Heoo hugohallqvist, welcome to the forums,
You should see this link here http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T400-amp-T500-Battery-size-what-sticks-out-...
Battery life wise, I can get around 1:30 minutes, pure gaming to about 4 hours. If you have battery issues, get the larger 9 cell and 3 cell one that fits into the Optical Drive Slot so you can get double battery life. It will be a lot heavier but except 6-8 hours.

Poor battery life and WiFi connectivity on iPhone 5s

I have bought a new iPhone 5s 16GB running iOS 8.1.2 3 days ago. The device that I have got has a poor battery life and WiFi connectivity. I have tried lots of methods given on the internet like turned off the auto-brightness, reset the phone to default settings.
Then contacted the Apple Care for battery issue. They asked for the diagnostics to check the problem. They said its happening because of the crash of inbuilt app Springboard asked me to try "Set up as new iPhone". Even after doing all these, I am still getting battery not more than 4 hours.
This is not expected from Apple. Such an awful experience on my first iPhone buying.

Where exactly did you buy this new 5S?

3GS battery life and current location problems

I have a 3GS. Until I took a holiday in Mexico it worked fine. On return, the battery life is one half or less as before. I thought I may have picked up a virus or something connecting to the local WiFi (data roaming turned off). I restored a backup and no change. Then I noticed that the 3GS was not able to find its location. I tried several suggestions from several forums to no avail.
The details:
I recently took a holiday in Mexico. On return I noticed that the battery was not holding a charge as well as it did before I departed or while I was in Mexico for that matter. On return it takes two to three charges to make it thru the day. My first thought was a virus or malware. I did some research on the forums and it was suggested that I do a restore. Ironically, gratefully, I had done a backup before I left so I preformed a restore. There was no change to battery usage. Trying more trouble shooting I discovered that my iPhone cannot find its current position. Once again I researched the forums. I tried changing the international location and back again, resetting the network settings and turning airplane mode on and off. I was able to find a location that was incorrect (several blocks away compared to right on before my holiday) one time and now once again my iPhone cannot find its/my location. On occasion, not every time, when trying to find my location I receive an error message “Could not activate cellular data network”. My theory is the battery life and in ability to find its location may be connected.
Any help will be appreciated.

I read this and felt a funny coming on....
I know its not funny when an appliance that we depend on doesn't work right, but my funny bone said, "Did you shake the phone to reset the GPS, and did you fly backwards from Mexico to reset everything as it was before you left?"
Forgive me!!!!

Poor battery life and high temperatures on MacBook Pro Retina 15"

I'm having never-ending problems with poor battery life and high temperatures on a MacBook Pro Retina 15"
I took it in for service and they told me it needed a new logic board and replaced it. When I asked why they were vague about the reasons, they said "it just needed one, it failed some test". I now have the computer back and it runs the same way it always did. I bought this laptop because it was supposedly capable of high end video editing in 1080P (or so Apple's website claims) and also photo editing.
"The processor, graphics, all-flash architecture, memory, and display in the 15-inch MacBook Pro give you unprecedented mobile video editing capabilities. Super-responsive flash storage delivers up to nine streams of 1080p ProRes (HQ) content for multicam editing in Final Cut Pro X,3 while the latest quad-core processors on the 15-inch MacBook Pro decode multiple streams of video, and a powerful GPU renders millions of pixels onto the screen. With flash storage that offers up to four times the performance of a traditional hard drive,1 you can even edit four streams of uncompressed 8-bit 1080p HD video, right from the internal storage on your 15-inch MacBook Pro with Retina display.4"
However, when I'm just browsing the web and emailing it runs quite warm and battery life is quite poor. Sometimes doing those same activities I would say it gets so warm it's almost uncomfortable to have on your lap and the fans are running fast enough to become noticably noisy. I'm also driving only one screen at and a time and I heard that the MacBook Pro can supposedly do three screens.
If actually try to do something like video editing with final cut pro the laptop gets really hot, the fans are on full blast and battery life drops to only an hour or two. I think when I rendered just a 3 or 4 minute clip once I got less than hour of battery life. I will have to time again.
Anyway most people (including the sales guys) are telling me no way this is not normal. When I play with demos in the store browsing the web they are not getting warm or hot to the touch. My friend's 2013 MacBook Air is also NOT getting warm to the touch doing the same activities.
I installed iStat Pro so I could check the temperature and fan speeds. I'm seeing temperatures of 70+ on the GPU, 85+ on the GPU diode and 65+ on the CPU heatsink along with elvated fan speeds above 5K which becomes noticeably noisy. I understand that might be normal for the most processor intensive tasks but it really doesn't seem right for just light web browsing and e-mailing. (I also may have viber and skype open but that shouldn't matter). CPU usage is usually running between 2-10% as this is all happening to.
Furthermore, straight from the specs:
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
I am assume "GPU" and "GPU diode" are temp measurements on the discrenete NVIDIA video card, especially since MacBook Airs from the same and newer generatio do not have this reading. Since Apple Claims the graphics "automatically switches" it seems all the harder to believe the GPU is reaching 85+ when in theory it shouldn't even be activated. I mean, shouldn't the INtel HD Graphics 4000 be capable of simple web browsing and e-mailing? Especially with only one screen activated (be it it the internal or an external)?
What should I do here? When I asked the repair guys "OK well what is the normal operating temp range for the various sensors" they said "Sorry Apple doesn't provide that info".

Yes I have.
Just web browsing and basically doing nothing I'm hear a lot of aduible fans, I'm getting 85C+ on GPU diode, 65+ on cpu heatsink. I since installed anohter program that shows me not just the CPU heatsink but the cores and the cores are at 90C+.
Seems like a lot of heat for doing nothing. Not only that but I have these problems with no external monitor while on battery power too.
I don't know what to do. They already replaced the logic board. Others seem to get advertised battery life out of Apple products and not have products that get **** near hot enough to burn you while just web browsing or watching a movie let alone advertised tasks like Photoshop and Final Cut Pro.

Battery Life and apps - specifically: Whatsapp, Gr...

Experiment: Smartphone battery life and Web 2.0 applications
Objective: To determine the battery life of a Nokia Symbian S60v3 {or ^3} phone under the use of web applications, the majority of which are social networking apps.
Apparatus: Nokia S60v3 FP1 (E90 Communicator, E71, etc) {or ^3 (N8, E7)}, Gravity, Nimbuzz, Nokia Email, Joikuspot, Whatsapp, MXit, BirdStep SmartConnect & Lights On. 3G/GPRS internet connection.
Method:
Install the latest versions of the softwares mentioned, activate Whatsapp (through sms). Use all apps as desired.
With Nokia Email, set sync period for wake/daytime only, i.e. when you are awake - say 06h45 to 22h45, daily.
For Network mode, select dual mode (S60v3: Menu/Tools/Settings/Phone/Network; ^3: Menu/Settings/Connectivity/Network)
At commencement of sleep period (first night), exit all apps. Set your alarm. In the morning, check Log (S60v3: Menu/Log; ^3: Menu/Applications/Tools/Log), scroll across to the list, note all Packet Data connection attempts.
Use applications at will on day two, shutting down/going offline with those you do not require. If the battery gets flat, charge it, continue to use apps/browsers if you can/need.
At commencement of sleep (second night), select go offline for Nokia Email (S60v3: Nokia Email {main menu}/Options/Go Offline), exit all others apps. In the morning, check and note Log parameters.
Repeat steps 4, 5 & 6 with varying Network mode (step 2). In all cases, phone should stay in a non-offline state - people should be able to reach you via phone call or sms at all times.
Make sure you clear browser cache every night prior to bedtime. You should check Browser (Menu/Web/Options/Clear Privacy Data/Clear Cache). Further, remove or disconnect battery to completely freshen the system.
Finally, delete Whatsapp, and repeat step number 4.
Observation:
The results for steps 1 to 8, inclusive, are essentially similar, in that access points (S60v3: Menu/Tools/Settings/Connection/Access Points & Menu/Tools/Sett. wizard, alternatively use your service provider to define access points) are activated throughout the sleep period, as follows (13 July 2011):
Internet .Vodacom(01): 00:38; 00:46; 00:54; 01:03, etc.
Internet.GPRS: 00:37; 00:41; 00:45; 00:49; 00:52; 00:57: 01:00 , etc.
Internet.GPRS(Joiku): 00:38; 00:46; 00:54; 01:02 , etc.
Vlive!: 00:39; 00:47; 00:55 , etc.
WAP.Vodacom: 00:39; 00:48; 00:53; 00:56 , etc.
Vlive!Streaming: 00:41; 00:48; 00:56 , etc.
Vlive!MMS: 00:43; 00:51; 00:58 , etc.
Internet.Vodacom: 00:37; 00:42; 00:45; 00:50; 00:58; 01:01 , etc.
BS_Gravity App: 00:41; 00:49; 00:57 , etc.
BS_Browser: 00:42; 00:50; 00:58 , etc.
Basically, an app is active throughout the the night. All data connections are outwards, last 5 or 8 seconds, a few last 34 seconds, most receive/transmit zero data, a few receive 1 kB. The final connection was an outward 12 minute 55 second at 05:08 using the Internet.Vodacom access point, sent 65 kB & received 360 kB.
Upon deletion of Whatsapp, no data connection attempt is made throughout the sleep period.
Conclusion: There is no way of turning off completely Whatsapp. Further, general phone use throughout the day disguises minute-by-minute data connection attempts by Whatsapp. This is wholly unacceptable app development in light of limited battery development for all smartphone platforms. All other apps installed on these devices have kill switches if you do not wish to continue use. All other apps, including the pricy Gravity, operate within the limits of the battery technology available and within the capabilities of the Symbian system. I do not think the trade off - all-encompassing IM service over sms sacrificing battery life is fair.
Facts:
BS_Gravity App & BS_Browser are access points defined in the Birdstep SmartConnect Client for Nokia ESeries phones. It's a client that aggregates normal network operator access points as well as Wi-Fi access points so that you do not have to continuously change access points on apps. BS_Gravity App for Gravity and all other social IM apps, BS_Browser for Web browser and Opera browsers.
Following deletion of Whatsapp, my E90 is back to around 4 hours battery duration under heavy use, primarily a very active Gravity & Web browser, up from about an hour with Whatsapp.
I am extremely content with general day to use of my Nokia phones, E90 & N8 alike. The E90 continues great operation, what I'd expect, the N8 covers base primarily browser capability - all other strengths complimentary.
Joikuspot is a considerable power user for extended use, but this is understandable, as the app gathers and transmits data which requires lots of power - basically, it's like having a 3G connection going boths ways. I'd imagine that any similar app on any competing platform saps power.
Recommendation: Install an on/off switch on the Whatsapp application. Please. Thank you.
Symbian connected me to the world, to my dreams.. Thank-you Nokia

I found unacceptable issues with the software, namely very high battery use. Many consumers will come to Nokia first before they complain to a developer - if indeed they ever do complain there. Use of the app in question paints Nokia batteries in a much harsher light than reality - people should be aware of this before they install the software.
There's a software issue here (developer x), and a software solution (developer y). The following link explains how to use y to defend from the excesses of x: http://softvision.posterous.com/39438314

When I got a new iPhone5, I experienced short battery life, and system sofware issues were not the cause. The camera also takes a blury picture regardless of lighting and I have the black one. Has anyone else experienced similar problems?

What makes you so sure it isn't software?
The camera can be focused by take the point of focus on the touch screen.
If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

Blackberry Torch 9810 battery life and build quality

I'm going to be getting a new Blackberry soon and I wanted to know what the 9810 was like. Can someone please tell me how it compares the the other Blackberry 7 devices, especially the battery life and the build quality of the handset?? I'd also like to know what the call quality of the handset is like, through the earpiece and the loudspeaker.
Thanks to anyone who replies.

Thanks for replying,
Were you a heavy user of your 9810 (i.e. leaving the phone signed into Facebook, twitter, etc... and heavy use of BBM)?
How long did the battery last on average?
And how strong and sturdy was the slider mechanism??
I use twitter all day long, facebook set to evey 3 hours, and have 11 BBM groups.
Usage is tough to measure as there are many factors. I can go a whole day or mabye need to change once during the day when too active on it.
my 9800 not 9810, lasted me very well and the slider was still like new. it is built well. I sold it to a friend so i could have a 9810.

2010 MBP battery life (and hot power pack)

Hi All.
2010 MBP here and I am finally getting around to troubleshooting very short - like 2 hour - battery life. The battery pack gets /very/ hot as well. I do let it run down to nothing once in awhile.
Supposedly (acconrding to experts on the list) the fact that the MBP gets /very/ hot to the touch on the bottom is not an issue based on the specs I posted (I forget the name of the software I used to generate these specs).
Can anyone help me with whether I should bring this in or if there is anything I can do to troubleshoot this further? I basically can't take if from my office to the living room without bringing the charger which is sort of annoying.
Can anyone offer this new mac user any help while I reasearch this further...?
- Jon

best bet is apple store. they will help you fix the problems you are having with your mac. It may also help if you don't run intens applications which use a lot of CPU and RAM. also running a lot of apps at once drains battery and strains the computer. Macs tend to get hot because of the aluminum, but it keeps the internal components cool. Battery life, I cannot help you there. Let me know if that was helpful

Curve 9300 Battery Life and CPU Discovery

Carrier: AT&T
Model: Curve 9300 3G / Wi-Fi
OS Version: 6.0 Bundle 2342 v 6.0.0.526 Platform 6.6.0.195
Since downloading 6.0 on 6/21 (two days ago), I have been having NUMEROUS issues with my BB Curve 9300 retaining battery as well as having the timer spin and stick.
I had only been using my phone to text or send emails, and had the wi-fi off, and even changed my screen to 20 backlight with 10 seconds, no vibration, and anything else I have read to see if that helped with battery life. The battery was draining at lighting speed, and I could not find the reason why. I think I may have found the culprit.
This morning, I took the battery out for five minutes and let it re-boot. That seemed to work great most of the day. Then a couple of hours ago I started to have the same issues again. I searched around on my phone and was able to find CPU usage, which revealed something very interesting that hopefully someone can explain on here:
I went to Options - Device - Application Management. Then I scrolled sideways to get to the CPU Usage area. I let that sit and watched it for a few minutes. What I found was that my "Phone" app (part of 6.0) was running at a very high CPU on and off when I wasn't even using the phone. For instance, yesterday, I MAYBE spoke on my phone for 15 minutes total, tops. The CPU shows that the "Phone" had 5Hr9M of use. Today, I probably spoke for 30 minutes total. It shows for today CPU is 7h18m. How is this possible? Just on the screen 2 seconds ago, and it went from 0% to 96% CPU usage for the "Phone". What is doing this? I believe that this app is draining my battery life. Anyone else have this issue? How can this be resolved? I hate this new 6.0 and hadn't downloaded it for my BB until two days ago, and totally regret it. Please help if anyone has any ideas here?

I downloaded 6 on my 9300 about 2 weeks ago, have had the same problem with draining battery fast, i hardly ever use my "phone". I use to get atleast 2 days with some left over on a charge, now it hardly last 8 hrs and I have to limit what I'm doing.
I just discovered all that cpu stuff last nite and was looking at it, I will have to see what it says my phone app is doing?
I just on my post yesterday and today got instructions on how to go back to os5, cuz I am completely not happy with 6, I do like the apps and layout of it, but just cant deal with no battery!

Does turning the LTE feature drain the battery life and battery lifespan?

Does turning on the LTE feature drain the battery life and lifespan of the iphone 5S. Also checking emails and going on the internet drains the lifespan of the battery?

yes
wifi and bluetooth does too
batteries lifespan is being zapped when used and also when not used
it will get worse and worse and in the end it will stop working

3g iPod battery life and hard drive head...

Hi all!
I have a 3G 20GB iPod, and sometimes the battery drains itself out even with a brand new battery and the iPod being shut off.
I can barely get 4-5 hours of playing time, no backlight, equaliser, and no songs skipping.
I found out that you can hear the head of the hard disk moving even when the iPod is turned off. One of my relative has a 3G 15GB iPod and she's experiencing the exact same problem of battery life, and her iPod's hard drive make's the exact same noise. And she also has a brand new battery.
So can you listen to your iPod, (even between times when the iPod has stored the data to it's RAM the head of the hard drive is still making some kind of movement) and tell me what you think.
I've tried to install all previous versions of iPod software to no avail.
For now I have completely erased the drive with "zero all" along with a surface test by Tech Tool Pro, and it seems to have made a difference.
Time will tell, post your observations and I will keep you posted.

The largest detractors for battery life are the obvious ones like backlight usage, anything that makes the HDD seek (FFW, skip track, etc...) using EQ, and volume. There are many other areas but most are pretty minor. Alot of it actually depends on the chip that regulates energy to the player. Supposedly we will be seeing new chips that double or triple battery life on these mp3 players in the near future but we shall see.
Hard disk is by far the biggest user, backlight uses some (but you wouldn't have the backlight on, and it's not good for the life of the EL panel either). EQ seems to have issues on some players where it uses far too much power in my opinion, specifically the Smart Volume function. I hope Creative can address the power demands of this if possible. Creative managed to double the base battery life of the Touch with the changes they made in some of the hardware, so greater li'ves are definitely achievable.
Rich_T: I've used your excellent test data as the start of a battery curve graph I'm putting together. I'm taking Creative's benchmark data and anything else I see to try and create curves for the players under different circumstances. I think once we have a base curve for one circumstance we can probably extrapolate it to all the other players, at least as a guess.
If anyone at Creative has any battery life figures for different scenarios (which I would be amazed if they didn't) it would be very useful

Short Battery Life and Very Slow Data on 4S

Short Battery Life and Very Slow Data on 4S,
anyone else noticing the slow speed of data on this phone?

Yes, I measure my slow data on Sprint in kpbs, not Mpbs. Like standard is download maybe 250kpbs, upload 100kpbs (that's 0.25 Mbps and 0.1 Mbps). On the same tower my buddy who has an AT&T iPhone 4 shows 2.5Mbps download and 1.5Mbps upload (that's 2500kbps and 1500kpbs), a LOT faster. Sprint has not been much help.

If i download CAD software how will it affect my battery life and macbook speed?

If i download CAD software how will it affect my battery life and computer speed?

Welcome to Apple Support Communities
CAD software requires the best CPU and GPU performance, so your battery life will be affected while running CAD apps. The same will happen with your computer performance with other apps, so if you do not need any application while using CAD apps, it is better to close them.
However, your battery life and your computer performance will be the same if they are closed. The only exception would be if your MacBook's hard drive is running out of free space
