April 10, 2007 Could the battery life challenge of mobile devices save the networks? Posted by Tommi at 04:12 PM | Categories: Devices

battery.jpg

The blog world seems to be a little upset by the (allegedly) poor battery life of the current über-phones Apple iPhone and Nokia N95. If you don't know what I'm talking about, check out:

The Apple Blog: Dvorak: iPhone battery dead after 40 minutes
Mobhappy: How To Shoot Your World-Beating Mobile Phone In The Foot

I don't want to get into this debate again, as we have already had great discussions about battery life in this blog. And as we concluded, there won't be easy answers in the future because:
- all the wonderful stuff in mobile devices improves exponentially
- battery technology improves more slowly (linearly)

Anyway, something odd struck me yesterday: the battery life dilemma might, paradoxically, be a good thing too. In a way.

Let me explain.

Charlie Schick wrote last December about something we all have experienced:

Like at all 'Net conferences, the folks at Le Web 3 were calling out for flat rate wireless data. Sounds great, but I don't think most operators are prepared for flat rate data from all their customers. I think for the most part, their networks are not designed to have a ton of folks sucking bandwidth from a single cell.

Jyri Engesrtöm referred to 'flat-rate hell' (or something like that) - what happened to AOL when everyone started 'getting' online life and dialing up in droves.

As a counterpoint, Orange was the provider of wifi services for the 1000 delegates at Le Web 3. The network was really flaky (I was one of the few actually posting photos - off my N73 via GPRS). I think it was the number of base stations and all the folks trying to get on that was the problem.

Ready for that in the real world?


This problem is, in its generalized form, known as Tragedy of the commons:
The parable demonstrates how free access and unrestricted demand for a finite resource ultimately dooms the resource through over-exploitation. This occurs because the benefits of exploitation accrue to individuals, each of which is motivated to maximize his or her own use of the resource, while the costs of exploitation are distributed between all those to whom the resource is available (which may be a wider class of individuals than those who are exploiting it).

For such problems, there are typically no easy answers. As the flat-fee plans come mainstream, the horror scenario would be that some ultra-heavy users could clog the whole network. After all, it wouldn't hurt you in any way if you to keep your data connections always on.

Now, as the battery life is likely to remain a major challenge in connected mobile devices, it sets up natural limits on how much individual people want to use the network. People will learn to use the network sparingly, despite having a flat-fee plan. And everybody wins, in a sense.

Heh. Always look on the bright side of life. Ta-dam-di-dam-di-dam.

(Ps. people struggling with battery life problems: apologies if this sounded like I was downplaying your distress. No intentions to do that. I think battery life is one of the most important things to take good care of nowadays.)

Wow, Tommi, that's one of the better "it's not a bug, it's a feature" pieces I've seen in a while :)

Nice try...! But actually an interesting point if you divorce it from the battery issue. That said the AOL stuff did sort itself out as I'm sure mobile would too. And networks have a lot more control over cutting people off if they breach AUPs etc.

Posted by: Rafe | April 10, 2007 06:53 PM

Interesting perspective. I think you have a point, and most will miss it and go back to the battery issue (which, as Rafe points out, is still a valid one. There's no reason the N95 shouldn't have gotten the battery that my N73 has) but I think there's alot of merit in the idea that it's one thing that can be used to limit network clog.

I also think that as new technologies emerge, they'll be more efficient at handling data.

Battery life to limit data traffic? That's a nice try indeed. First, we convince the whole world that 3G is absolutely necessary for the better of this society. And then, when we figure out that we opened the box of Pandorra with the demand for flat rate, we point to an underdeveloped feature of modern phones, good batteries, to put the lid back on the box.

As said, nice try but too simple minded, really.

On a serious note: there is serious work in 'unclogging' the networks despite flat rate. I would prefer these mechanisms getting in place and Nokia (as well as other vendors) doing their homework on batteries so that my 'multimedia computer' actually last some time longer.

I am working in the environmental sector, so just wanted to note that although your analogy to the Tragedy of the Commons helps to illustrate the point, the difference of course is that in the generic Tragedy of the Commons dilemma the use of that resource is indeed free and/or largely unregulated. Global climate change being the most pertinent example of our times.

Anyway, this reminded me also of something Nokia launched maybe a year or two ago: some kind of solution where the networks could push media content to subscibed customers at night time, when network demand is low, thereby allowing them to optimize on the network capacity. Did that product ever take off?

ps. The captcha code required to post a comment (if not typekey member) sucks.. some of them are extremly unclear.

I hope that we can get rid of that horrible captcha code already during this week.

I don't think it's good to tie these issues together. Battey life tech trends suck, but hey, that's why we have chargers.

The lack of flat rate for mobile internet however is the biggest challenge that Nokia faces as we reinvent ourselves as an "internet company" whatever that may ultimately mean.

"There is only one Internet" Kallasvuo says...

And he's right. What is more, shifting data around is not a premium service, no matter how it's currently charged when it becomes "mobile".

The flip side of the battery issue (that surely won't go away anytime soon) would be to off-load processing from the terminal on to network-resident resources. Of course, there are situations/applications where this suits better than in others.

Hello Tommi,

Even with a mobile flatrate I think it is unlikely that we will see wireless network congestions for two reasons: Power users will still tend to DSL or cable as prices are likely to remain lower than 3G/4G wireless flat rates. And should networks come into a state which is perceived as overload, data rates will drop which in turn is again something power users will not like. Thus, they will again drift over to DSL and that way free up resources in the wireless network. So I think there is a good auto control mechanism built into the system. And on top of that I don't really think it is necessary to have uncapped data usage price plans to get users on the network and thus make money. What's required is a large enough bucket of data a month that convinces users that it's good enough for their purpose and a clear notification when they overstep their subscription. Austrian operator ONE has an interesting approach to this: http://mobilesociety.typepad.com/mobile_life/2007/02/there_are_those.html

Cheers,
Martin

In long term - strategic thinking - the ultimate goal of mobility does not permit the path you described. There is a physical limit here, bound by the energy we can store and the energy we need to communicate but I think that the linear improvement you expect for battery life will not hold for the energy needed to communicate. Or better said, I hope it will be exponential improvement in screen technology & back lighting, wireless LAN processors and power requirement, processor power, etc...

for the short term, my expectation is that winners on the market wil be characterized by reasonably long battery life & reasonably good capabilities to communicate... I know... That avoids a clear answer about the future of the N95.

Although there is something you CAN do:
Educate users! What do we expect from a laptop? 2-3-4-5 hours? If we accept that Nokia's pocket computers ARE computers, 18-24 hours under heavy load should suffice...

I look at my E70 as a minilaptop with a battery life for one day of surfing on Wlan-s. Pretty good from that perspective... :-)

by the way in my opinion the E70 is the revolution... Are ther any public sales figures about the E70? I only see that shops are running out of them constantly in Finland...

Nice misdirection. But of course bandwidth isn't actually a finite resource, and certainly it is not one that can be spoiled for the masses by the greed of a few.

Over and over for the last couple of decades available bandwidth has increased to cope with demand,and it will continue to do so because everyone involved is motivated in the direction of more is better.

Thank you for this outstanding article.I thought Centrino was the best technology for laptop battery performance.
