Even though I do not have any iPhone, I am reading all the news and discussions in the forums about this new toy. I am not into all the nice features, I am more looking into the battery issues. There are a lot of helpful advises how you can save energy on the new iPhone. Here I list some of them
- Do turn off WLAN
- Do turn off Bluetooth
- Reduce the brightness of the display
- Do not check too often your email
- Switch of 3G and use 2G instead (so why was there a 3G iPhone at all?, yes the GPS stuff!)
and here my personal advise
- Do not switch it on at all (operational time -> infinity).
Even though I have to admit that battery issues are not limited to the iPhone, I am quite happy to read all about it and use it for my students to explain why we need to work on energy saving strategies at all. As my research area is on energy saving mechanisms, the iPhone is a very good example. Steve Jobs made a very clever statement referring to the 3G chipset as power hogs. At that time he used this as an excuse why there is no 3G chipset on the devices. If you look at http://www.apple.com/iphone/specs.htm, you can see that APPLE states, that the talk time for 2G is twice as high as for 3G. The GPS chipset is switched off automatically if not needed, but the 3G can only switched off manually.Therefore I changed the slogan of Apple "Twice as fast - Half the price" to "Twice as fast - Half the battery"
So whatever the 4G technology will be, as you should rarely use 3G, 4G you should never use if you care about battery. So long, I need to read more about it, very good motivation for my daily work.

I really like iphones. They are an entertaining electronic machine. I really interested in new model. It is faster and high battery power than previous version. It is a very good example in energy saving mechanism.

Today it was the iPhone 3G launchment in 22 years around the globe. Almost every newspapers had a note or even entire pages talking about this... phone. Is it the iPhone the Nokia's funeral, on smartphones devices?
We didn't see another crazy mega-succesful phone since the launchment of the Motorola RAZR V3, 4 years ago. Motorola V3 has become the most selling mobile phone in history. Now V3 is dead.
It is dead because Motorola didn't launch anything better and more inovating, next to V3. So the question is: is iPhone about to stay in our lives since now and other companies will loose costumers because of this Apple's mega success, or is it just must-have item for now?
The difference is that Razr V3 had a poor software and it was the most successful phone because of it's design, but iPhone has become a mega hit not just because it's uncommon design, but yes for it's inovating software. An inovating software that Nokia and other companies don't have.
iPhone is for sure the most carismatic phone ever made. The question is: iPhone success will last forever, or it will have the same destiny than V3? Maybe yes, maybe not.
Maybe yes if Apple does not create more inovating devices like this one, in the next times, but maybe not because Mac is selling more and more every year, maybe yes because despite there are hundreds of mp3 player's by Sony, Creative, Nokia and Sony Ericsson's mobile devices with powerful mp3 players, and many other companies, despite all this, iPod is still a mega hit, a must-have for every music lovers, because it is made by Apple, because it has an original and even so simple design, because... what more? It's Apple. Who has an iPhone, can easier buy mps songs on iTunes and play them easier on their Mac as well. It means that Apple is earning money through 3 products, one takes to the other.
The point is: Is Nokia and other companies doing well their homework, when a single device like this one is going into our lives around the globe in a massive way like iPhone's doing?
Nokia has become famous because of it's original devices design, that no other company would imagine that it could be possible to be made, and the some about the software. But since some years ago, we don't see any must-have Nokia device anymore, in what concerns about the design and software. Almost everything you get on a Nokia device, the other companies have it too, since the same level of design and software. Nokia is failing on US market since ever, maybe the very best market in the world they could have.
Nokia is probably being successful in it's lovely China and India, but be careful, iPhone and other mobile companies are not in coma at all, and they will fight for those markets too, and it will become quite embaressing for Nokia, as a company as it is, to go #2 in Europe and maybe other places like latin America, for consumers wonder. Maybe you should start hiring again the same industrial designers and developpers who have created N-Gage, 7610, the Fashion Collection 3 years ago, 3650, and many other weird and wonderful and respected and successful devices that Nokia made before. Maybe a lot of Nokia developpers, as they are, they obviously prefer Nokia's software, but the other hundreds of millions of mobile consumers may not care about that when they have the best design and inovating software on a device like iPhone, for example. As the subject title sugests, Nokia must kill iPhone, before iPhone kills Nokia.

I'm reminded of the line towards the end of Bladerunner "The light that burns twice as bright burns for half as long - and you have burned so very, very brightly, Roy."

It seems that almost every new electronic gizmo eats up batteries quickly. That's one of the reasons I avoid new gizmos - every time I try to turn one on to use it the batteries are dead and have to be recharged, which is a huge pain in the neck!
Battery life

Battery life has always been one of the major issue with a PDA type phone for me. Until just recently, I have not had any phone that would give me more than 1 day of use and have to be charged every night. Now I have an Nokia E71 and I am very impressed with the battery life on this phone. Even after using it for numerous calls, 1 hour of WiFi, GPS, Push email active and general use of the applications sitting in an airport waiting for my delayed flight, I still had at least 40% left at the end of an 18 hour day. Could not say that for my previous phone, an Imate 9502 which had below 20% with only a 3rd of that kind of usage. Most impressed with Nokia on this one. I think the E71 will be with me for a quite a while.
