Survey: Recent T-Series Battery Life

Hello everyone!
I've reposted this survey on Lenovo Forums due to it's increasing popularity and the relative stagnancy on TPF. I hope to get some more of your input and support over here on Lenovo forums. (mods, I put it in this subforum because it's primarily concerned with recent T-series)
I am conducting a survey (more like research) in order to find a correlation between components (software and hardware) and battery life. I am doing this because I have two friends with identically configured T510's (except for OS architecture) with vastly differing battery lives. In addition, my own T400 doesn't quite meet the tabook ratings for battery life. But beyond that, this information will benefit those who already own a ThinkPad (how to improve their battery runtimes) and prospective ThinkPad owners (how to pick the most power efficient components). Thus I am asking for a few minutes of your time for the following information (feel free to add anything relevant; anything at all!):
Model:
CPU:
GPU (specify switchability):
HDD (including manufacturer):
RAM configuration:
Wireless Adapter:
Bluetooth:
WWAN:
Display (manufacturer if convenient):
Battery (# of cells and % wear):
Advertised Battery Life (tabook, optional):
Actual Battery Runtime*:
Usual Battery Display Brightness:
Primary OS (x86 or x64 and SP and if is preloaded):
Firewall/Antivirus Solution:
Browser(s):
Task Resident Programs:
Please refrain from commenting on other people's posts on this thread for the sake of tidiness.
I am primarily interested in recent T-Series as the W-Series generally lives with the expectation of lower battery life, and the X-Series with higher battery life, but post anyway.
Thank you in advance for your participation. I will post tallied results at the end of the year. Hopefully enough people will have chimed in.
Happy ThinkPadding!
* Actual battery life will be defined as the runtime under normal office conditions/light web browsing/note taking/etc with wifi on and BT/WWAN/WUSB off. It's not very rigorous, but it's a tradeoff between statistical accuracy and convenience. OPTIONAL: Extrapolations of a full battery runtime (in case you use charging thresholds) can be done using the formula Δt/Δ%, where Δt is the runtime to drain Δ%, where Δ% ie expressed as a decimal value between 0 and 1. Or you could just write "3 hours on 80%"
W520: i7-2720QM, Q2000M at 1080/688/1376, 21GB RAM, 500GB + 750GB HDD, FHD screen
X61T: L7500, 3GB RAM, 500GB HDD, XGA screen, Ultrabase
Y3P: 5Y70, 8GB RAM, 256GB SSD, QHD+ screen

Just a quick note - if you have a T410 or T510 and find that you have a battery that is declinging in full charge capacity and run time at an accelerated rate, you may need to update the system BIOS and battery firmware to resolve this. Following the update, you will need to charge cycle the battery once or twice (or perform the battery reset).
Heres a link for more info - there are also similar updates available for W, SL, L, Edge series systems..
I realize that the survey and responses span several generations of systems, but I thought this was still worth mentioning .
Best regards,

I recently just updated my iPhone 4s to 5.0.1 and I am losing battery life at a faster rate. How do I help my battery life or can I go back to the old system?

This is my first iPhone I am having problems with my battery life. I recently updated to the new operating system for the iPhone 4S. I am losing battery life at a quick rate is there anything that I can do.

You can search the forum and read the many helpful posts with suggestions on how to improve your battery life.

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...

My battery life on my iphone 4 has been TERRIBLE since the most recent iOS update!

My battery life on my iphone 4 has been TERRIBLE since the most recent iOS update. Is anyone else experiencing this? At night I use a white noise app, and up to the most recent update, I never was below half battery in the morning. Now my phone is completely dead in the morning. I've noticed it draining faster in general since the update as well, but that particular app was just the best example.

One of the new features on the iPhone 4 is Multitasking ; it lets you do multiple things at once. For example, while iPhone is busy downloading a movie from iTunes, you can switch to the Safari app and browse IMDb in the meantime. So there's no more waiting around.
Each time you open an app and then press the home button, the app is still open. At the end, you may have too many apps opened at the same time.
To close apps, double click on the home button. Your opened apps will appear; hold one of them, then click on the red close to close an app.
Close as many as possible if you don't need them.

All you have to do is double tap the home button to bring up the multi-tasking view, then swipe up on the screenshot of the app you want to exit.

Hi, I have an iPhone 5s, recently its been a lot hotter than usual, also the battery life is going down a lot faster than usual, and it takes absolutely ages to charge up. There must be a serious problem with the battery, any ideas? thanks

HT1430 I have the Iphone 5 and just recently updated to IOS 6.1.3 and my battery life is just not what it was with the 6.1.2. I can start a day at 100% and in 6 to 7 hours be at 18%, (this actually occurred this past Monday) for no reason.

Hello, has anyone had problems with increase rate of battery life depletion? When I say increased rate I mean loosing maybe 80% in a 7 hour time frame while using the Iphone for nothing more than checking weather or stocks? This started after I went to the IOS 6.1.3. Before I could easily get 3 days out of the phone. Now I am wondering if it will hold the charge before I get home from work.

Hi imobl,
Thanks for your response, I forgot to add that the five 3uk sims we have in use, I have tried all of them none of them are recongnised non of them have pin codes, I even purchased four more sims Tmobile (original carrier) Vodaphone, 3 and giffgaff.

Battery Life is Very Short Recently

Hi, my MacBook Pro battery life has been really dying quickly in the past couple weeks. My MacBook Pro is new as of December, and has only gone through 107 cycles. I am only running Chrome and Microsoft Word and a couple of other applications (Mail and iCal) as occasionally needed. I have been using my computer for all of 20 minutes now, running just Chrome, and I have burned the battery down to 82% and it only has 2:13 left. I don't really know what is going on, and I like to think that I keep very good care of my computer. Any suggestions as to why this is happening? I am currently running 10.8.3 with 4GB of RAM.

While it's normal for your battery to discharge faster when running certain applications. Having your screen set at the highest brightness settings also plays a role.
Try this - set your screen brigthness down to 50% - turn bluetooth off if you're not using it.
Google Chrome does use up your battery resources - try using firefox instead.
With all those apps you have running in the background - it is normal for your battery to discharge faster.
Open up activity monitor (have a look at my screenshot below) - under " All Processes " not my " My Processes " see what using 10% and above in your % CPU section - highlight it and hit quit process.
See if that improves your battery life.
107 Cycles is quite high for 4 month old Macbook Pro.
You can keep it plugged in when you're close to a power outlet - it will not damage/overcharge your battery if you keep it plugged in.

Portege series, different battery life on R100 and M100?

Hello everybody,
I want to buy a new notebook with high battery life for mobile working. The R100 and M100 are shortlisted, but does anybody know if there are differences in battery life. I have tested the two NBs at my dealer, but I have no experience to work with them over a long time.
Bye Tanya-LB

Hi Tanya,
I had the honor to test these two notebooks in our company. They are both developed as business model for high mobility and battery life. On the one side you have the R100 with a ULV Centrino with 900Mhz (ULV = Ultra Low Voltage) and a lithium-ion-polymer battery. This combination enables a battery life of 2 hours and with the second additional battery up to 6.4 hours.
On the other side you have the M100 with a LV Centrino with 1200Mhz (LV = Low Voltage) and lithium-ion battery. If you need only one battery the discharging in use is about 4.5 hours and with an additional battery up to very good 8.5 hours.
So in my opinion these notebooks are really well designed and accomplish the specifications of high mobility. The M100 has the higher battery life and performance.
If you have further question, ask me.
You could also see the technical specifications at the Toshiba site

in the Product menu.
Hopefully this will help you.

Battery life on a Q10 after the recent update to OS 10.3.1

I purchased my Q10 in November of 2013 and one of the best things about it was the battery life. One time the battery lasted for four days (albeit with minimal phone use). I upgraded to OS 10.3.1 a couple of days ago and have noticed a drastic decrease in the life of my battery, despite the claim that the new OS was better at battery management. I went to bed last night with 46% battery remaining and woke up 9 hours later to find my phone completely dead. I even had the Wifi off and Bedside Mode on.
Has anyone else noticed this? Is there some way that I can get better battery management?
Jeremy

Try a hard reboot and then give it a few days, a new OS often means some background housekeeping is going on (this is more noticeable on clean installs).
Check the Battery in Settings -> App Manager -> Device Monitor after a week or so and see if anything obvious is causing the degradation.
If you've been helped click on , if you've been saved buy the app.

Battery life after recent update

Just installed an update on my Samsung Galaxy Nexus last night, which brought me up to 4.2.2. Battery life is absolutely non-existent afterwards. Normally, I go from 6:00 am to about 7:00pm before i have to put the phone on the charger. This morning, battery went from 80% to 14% in an hour.
Is there a way to roll back? Or is there a fix on the way? please help, as the USB cable plugged into my computer is not even able to keep up and recharge the phone with it on. It's off now, and charging, but that means i'm unavailable on the phone, not good.

No there isn't any official way to roll back an update.
I wouldn't use the USB cable connected to the computer to charge the phone. Plug it into the wall charger.

Battery life survey

Hi everyone.
I am getting about two hours of usage on my PB after a full charge (I have calibrated my battery when I got my PB, then several times thereafter and last about one month ago). I have had my PB since Feb 05.
My typical usage at any given time: Bluetooth & Airport on with about 6-7 applications running.
Please post your battery life below.
Thank you.

I was getting only 1-2 hours the first year and 1 hour the second....I tried a lot of things to fix this. I suggest that everyone reads http://www.batteryuniversity.com/ See if you are taking care of your battery.
My battery (model A1060) was not on the list for replacement, but I think it should be included. My 12 ibook G3 (4 year old) still has a great battery and runs for 3-4 hours typical (airport on). Otherwise I think it is too small a machine for the processor and the battery should be closer to the fan and further from the processor. The machine runs too HOT.
I reported this to Apple and would love to here if others are having the same problem. I was able to get a free replacement because I noted a problem from day one about excessive heat from the processor. You should note your battery model number too.

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.

X1-00 dual sim Less battery life

Recently i purchased x1-00 Dual sim mobile.
Its manual claims a battery ( stdby) life of some 1030 hrs.
however on checking ( stdby with two sims ) it is lasting only 72 hrs appx.
On approaching Nokia dealer they say its a cheap model so dont go by claims.
it has contact view problem where you can not select the searched contact ,if u r in doing it from inside of other menu like sms and adding to existing contacts.
what is the solution apparently this phone can notbe connected to pC
or how to upgrade FW

Concerning battery life until it has been discharged fully and charged fully over several cycles it will not deliver maximum capacity.
As a Series 30 device designed for emerging markets neither ability to connect to PC or software upgrade is a priority; music can always be dragged onto microSD.
