T410 vs T410s [battery life comparison] ?

I'm currently thinking about buying either T410 or T410s laptops. T410s is tempting for its size and nice form factor, but I've read that there are some notable differences in construction between it and the t410, and one of them is quite different battery construction, which may result in lower battery life in t410s compared to t410.
As both mobility and battery life are important to me, I need to decide which one is more important - T410 is a little bulkier and heavier than T410s, but may work longer. That's where I need Your help - what are the differences?
I'd like to be able to get about 4 hours or more of DVD playback, with all desktop effects turned off, wireless off, about half of monitor brightness. Is this possible?
And what about battery life while browsing the internet wirelessly? Can You give any examples of usage and estimates of battery life for both T410 and T410s?
PS.: As I value mobility (as previously said) I think I'd choose the 6-cell battery and Ultrabay battery. (I know it's important)

hey ssbc,
i recommend using this psref : http://www.lenovo.com/psref/pdf/index.pdf
to compare the difference in specs.
for the battery consumption, do note that the consumption is based on usage, brightness of screens and other factors.
thus if you would like to do a comparison, both units should be using the same power manager versions and both be at the same settings

Battery life comparison between 1.0.2 and 1.1.1

I had to have Apple Care send me a replacement phone because of battery issues.
I received the replacement phone, and interestingly, it still had the 1.0.2 firmware on it.
If enough people are interested here, I can run a fairly scientific test to see if there's any difference between 1.0.2 and 1.1.1 in regard to battery life.
I could leave the 1.0.2 software on it, charge it fully, then at 10 pm, put it in a specific place in my house, then see what the battery is at @ 7 am. Then, the next day, I can update to 1.1.1 and do exactly the same thing with the same settings.
But if the battery issue has been put to rest, or if people think this isn't a scientific test at all I don't want to waste my time.

Your post is helpful in that it points out that it'd be a very difficult thing to do a scientific test that proves anything.
In your usage, you left out surfing the web, which I do quite avidly. I also check my email much more frequently (every 30 minutes, as I've said). I can't test for surfing the web while I'm sleeping.
Your saying that updates have nothing to do with the battery is not at all a scientific case study and has very little resonance, but it's great that in your personal experience you haven't seen a degradation in battery life. A bug can rear it's ugly head in many different places, and your usage of the phone may not hit it if in fact there is one.
Just as an endless loop in a program can cause a computer's CPU to spike if an uncommon set of events leads to it, something could be happening with the phone for some users who are using their phone in a specific way.
So, having said that, I think I might've answered my own question in that there might not be any scientific way to do a test.

X61 battery life

I am yet another X61 customer who is extremely disappointed in the short battery life of this model.  Our company previously had 35 of the X30/X31 model, and all of those batteries lasted four to five years. We now have 39 X61's. Imagine my surprise when multiple users started notifying me that the batteries were dying after only 16-17 months of use.
Here's my question:  I have two users whose four-cell lithium ion enhanced batteries died after 16 months of use.  One user reports that he uses his laptop on battery power twice a day every workday during his train ride to and from work. The other user reports that she rarely if ever uses battery power since she's in the office virtually all of the time. Why did both batteries die within weeks of each other, when one had heavy use and the other had virtually no battery use?
My only consolation is that I located new generic Li-ion batteries from an eBay seller for less than half the price that Lenovo is asking, even at Lenovo's sale price. I just ordered my first dozen; I'm sure I'll be ordering a couple dozen more in the coming months.

Welcome to the forum!
While there are a few Lenovo employees roaming around in here helping out on a volunteer basis, this is not an official support channel. Instead, this is designed to be a user-to-user support and discussion forum. You may or may not get an answer directly from one of the Lenovo employees as there are way more of us than them and all of them, even Mark, have full-time jobs doing other things.
It's likely that no one who knows the answer to your question has seen it. There are a number of variables to consider when trying to determine why a battery may have died. How long is user #1's train ride, and what was the cycle count on it? Did he drain the battery twice a day 5 days a week for 16 months? User #2's battery was never used but stayed the notebook doing short cycles which tends to kill a battery. On the other hand, she probably never lost any data during a power outage because the battery was there to keep the system running until she could gracefully power it off.
Notebook batteries are consumables just like the batteries in your car and flashlight, and usage patterns play a big part in how long they'll last. The fact that these two died within a week of one another is probably just a fluke.

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 .

HDD adaptor vs battery life...?

Hi guys,
Pardon me if my question have been discussed before, could not locate any threads...
I am thinking of buying the HDD adaptor for my T410 so that I can place a 2nd HDD in the optical drive, thought of putting in 1Tb. My question is, how much battery life will be affected if I go that direction?
Any inputs will be greatly appreciated
omar
Solved!
Go to Solution.

Generally it will drain as much as relugar HDD inside. Usually going to have impact about 30-60 mins battery life - depending on usage of that HDD.
7200rpm HDDs drain more and often are more loud and definitelly get a bit more hot than 5400 prm. Therefore I would suggest to with 5400rpm HDD.

T420s hard drive noise / speed /battery life trade off and Screen Roll Cage Info

I know this is a brand new laptop but has anyone over at lenovo spent enough time with both the 7200 rpm and the 5400 rpm version of the 320GB hard drive in this laptop? I am trying to decide between ordering one and would like to get the 7200 rpm but I really dislike hard drive spinning noises in quiet environments. I am currently using the t400 with the 5400 RPM 320Gb drive (which I realize may be different from the drives in the new t420s) and do not find the noise objectionable but would like to get the 7200 in the t420s if there is no noise penalty and very little battery life penalty. Also, does the T420s have a "screen" roll cage like my current T400. I had heard that the T410 did away with the screen roll cages....
Thank You for any assistance.
Solved!
Go to Solution.

The T420s's rollcage is made of a hybrid carbon fibre reinforced plastic. It's not metal since that interferes with the wireless signal.
It's apparently a bit better than the one the T510 has right now (which is the same carbon-reinforced plastic)- and the T410, with a "weaker" roll cage, should pass a 1.6 metre drop anyways.
I can vouch for that plastic's use since you can step on another laptop who's lid (I'm pretty sure it's made from this) is made from that (an old 600E) and it will survive.
Also, the noise isn't all that different for 5400 RPM vs 7200 RPM. The fan will be louder if you are using it.
And if you really hate hard drive sound and want a bigger boost than just an RPM bump, consider an SSD. That'll blow any hard drive out of the water in terms of speed, but will do the same to your wallet if you need anything larger than 40-60 GB. And, if you choose to do this, be aware that the T420s only takes SSD's that are 7mm high- so you'll probably need to get an X25-M or Intel 320 to accommodate that.

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

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...

MacBook Air battery life/standby time destroyed by Lion!

My girlfriend's 2010 MBA used to be able to be in standby mode forever (for weeks, if not the advertised month) and still maintain a charge with Snow Leopard. After upgrading to Lion, the battery drains overnight.
Anyone else have this issue?
And does anyone know how to solve it? I tried resetting the SMC which seems to have helped battery life slightly when the computer is in use but had no effect on standby time.
Any help would be much appreciated.

My wife's MBA (Late-2010 11" 2GB) had its standby and operating times destroyed by Lion. Prior to the Lion upgrade, useful operating time were 5+ hours and standby forever it seemed. After the Lion upgrade, immediately useful battery life was 2 hours and standby barely lasted overnight. I ran Coconut batttery to discover that, at idle with no applications running in the foreground, the machine was drawing 16.7 watts. The case was also uncomfortably warm when operating on battery. On charge, it showed 434 watts (shocking don't know if this is normal for Snow Leopard though). My MBP (mid-2010 13" 8GB Snow Leopard 10.6.8) only consumes 9 watts at idle on battery by comparison (and it doesn't have SSD and other power saving features available on the MBA).
So, I downgraded to Snow Leopard by reinstalling the machine from scratch. Power consumption in coconut battery shows 5 watts at idle with no applications. When I wake the machine from standby, coconut battery shows 0.1 watt consumption. So, I believe this may have solved the battery longevity problems. Since I only downgraded today, I have to test for some time before I can declare the problem fixed.

Average battery life of 3GS?

How long should I expect the battery to last in an iPhone 3GS while in Airplane Mode? Since upgrading to 4.1, my phone's battery will discharge completely overnight, even if left in Airplane mode.
I am not asking for any fixes (I've already performed a number of the suggested fixes in this forum and I have spoken w/Apple tech support), nor am I suggesting that my battery life is directly related to the upgrade; I just want to know for purposes of comparison what other users are experiencing.

Thank you for sharing your experiences, Alain. At this time I have a replacement 3GS while Apple tries to figure out the problem with mine. In all likelihood I will probably end up keeping the replacement. Before iTunes would allow me to restore from backup on the new/replacement phone, I had to upgrade the OS to 4.1.
The first night, the battery was 100% and I left the phone on all night (not in Airplane mode, Bluetooth off, push notification for mail off) and I had 30% battery life left after about 8 hours. It's an improvement over what I had been experiencing on my old phone, but still not ideal by any stretch.
I will heed your advice and on this phone I won't open the Game Center. I'd like to delete it altogether if I could!
If the battery drain worsens on this new phone, I will try resetting and restoring as you suggest, though I found that the apps don't restore properly if you have any folders, and it's a PITA to reorganize them.

T400 Dock and Batteries - will they fit a new T410 or T410s?

I have a T400 with docking station and extra high capacity battteries. I'm looking at a new T410 and T410s - will my docking station work? How about the batteries?

the T400 uses a different battery to the T410/T410s (these two machines also use a different battery to each other).
T400 battery is compatible only with R400, R61/T61 with 14.1 inch widescreen.
Advanced dock and advanced mini dock (and the port replicator) used for T400, is compatible with:
T6x, R6x, Z6x, T400/T500/W500, R400/R500

T420 vs T420s Battery Life/ Specs

Appreciate any input provided on the differences in specs and battery life between a 6 cell battery on both systems.
Was told the 420s 6 cell would last 6 to 10 hours, and on the initial 100% charge it read 3:50 in time, and after about 15 minutes it read about 4:15. Not sure why this is, but I'd like to do an apples to apples comparison of the two machines given indentical configurations.
Thanks.

Battery Life on a 60GB 5th Gen Ipod!!

Does anyone know what the battery life is supposed to be (what does Apple claim) on the 5th Gen 60 GB Ipod?? My video's are only playing for approx 2 hours, is that right?? Apple claims up to 20 hours for music and I am getting 6. I have followed ALL the battery life saving tips they give. What's the deal.

Yes I played JUST music. Do you know what Apple Claims the battery life should be for both music and then for video's? My 60GB photo lasted closer to 10 hours playing music....bummer.
It is frustrating to read all the poor batt performance claims, so I would like to make sure that everyone understands... Apple does their tests under ideal conditions, as any person would expect. But there is no benefit to them in overstating the results since this would certainly raise the ire or their users.
Ideal conditions in general are:
Batt tests are done with 128 kbps AAC music only, file size of 4 MB per song, backlight off, Repeat-Off, EQ-Off, Soundcheck-Off, continuous (one long playlist) on a conditioned battery (several normal batt recharge cycles completed), nominal temperature.
Now, I have a 5g-60 and have been seeing roughly what I expected, between 16-17+ hours depending upon settings and how much fiddling I do with the controls during play.
Here is an excerpt from iLounge.com's report:
Apple claims that the new 30GB iPod will play music for 14 hours, photo and music slideshows for 3 hours, and iPod on-screen video for 2 hours. In our tests, it outperformed Apple's claims in two out of three categories, but missed one as well. It played music for 15 hours and 30 minutes, photo slideshows for 2 hours and 32 minutes, on-iPod video for 2 hours and 10 minutes, and iPod-to-TV video for 3 hours and 10 minutes. Apple similarly claims that the new 60GB iPod will play music for 20 hours, photo and music slideshows for 4 hours, and video for 3 hours. In our tests, it missed the music claim by 10 minutes, playing for 19 hours, 50 minutes, but exceeded Apple's photo and video claims, playing a music photo slideshow for 4 hours, 47 minutes, iPod-screen video for 3 hours, 23 minutes, and on-TV video for a hefty 5 hours and 24 minutes.
To provide a frame of reference, color 4G iPods were able to achieve music playback times of around 17 hours a piece, beating Apple's estimates by 2 hours. By comparison, the black-and-white 4G iPod that was introduced last July ran for 12-14 hours, and 3G iPods ran for much less. Therefore, regardless of whether they meet or miss Apple's estimates, the new iPods are at least acceptable overall. The 30GB 5G iPod is a bit under the color 4G in battery performance, while the 60GB 5G iPod is superior. The only iPod that's ever done better than the 60GB 5G was the second-generation iPod mini, which actually ran for over 26 hours in our testing.
The two biggest contributors to sapping the battery's energy are use of the backlight and hard drive. Whenever you use the volume control, menu system or select your favorite song as the next one, you are draining the battery at an exponential rate.

Does Mavericks have any effect on MBP battery life?

Does updating to Mavericks have any effect on the battery life of the MacBook Pro?

It's suppose to have a postive affect on battery life. At least that's what I'm seeing in comparison to OS X Mountain Lion (Macbook Pro Retina).
See Conclusion at the bottom of this PDF from Apple. You can also skim through the PDF to see how battery life is extended.

Possible Internet Tethering/Battery Life Issue

When either Cellular Data is turned Off, or Airplane Mode is turned On, Internet Tethering (Settings>General>Network) appears to have some process that runs continually in the background (evident by continuously spinning wheel next to the option). The running process has a demonstratively negative impact on battery life (1/3 reduction in ~ 30 mins). The Apple Genius at my local Apple Store and I verified the issue on numerous iPhone 4s that were on display. Turning Cellular Data On and ensuring the phone is not in Airplane Mode stops the activity. But obviously that defeats the purpose of having those options.
So if you are experiencing poor battery life, this might be your issue.

Could this be causing the unexplained usage and data transfer? I have been trying to find what is causing this. http://discussions.apple.com/thread.jspa?threadID=2603718&tstart=0

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.
