How long is a bit of string?
A few calls and a few text or emails and a photo and looking a some date in notes and maybe the use of an app, like a calculator and there should be no problem. The rest of the time you should be doing other things like being at work or getting a life.
If you are running a small business from your smartphone or using it as an ipod, a tom-tom or a games machine or spend all day on twitter, you should carry a few spare charged batteries in you pocket
Thats the one subject were a law should be brought in,Batteries an Batterylife on Mobiles,the companies produce different mobiles but do not seem to consider the cost of not just buying the mobile but running it,Batteries used to last 2-3 days but modern mobiles the batterylife on mobiles usually 1-2 days,they put loads of features on the mobiles but you can not use them to often because it drains the batteries out to quickly,Nokias seem to have the Strongest batteries but Samsung the Worst ,We also want the companies to make a Standard Charger they all use the same on Every mobile produced nowdays,then there no searching to do looking for a certain charger for the certain model,Why can"t all the Companies use the same Charger on any mobile produced now

Given the small screens they should performe similar to the iphone which they do. This tells me that the battery management efficiency of symbian is not really a big factor.
It is very interesting how did you compare Omnia HD with Iphone in measuring max battery. I'll give you some examples, please be free to try:
1. I'm jogging and my omnia hd is recording gps track of my marathon and at the same time it streams via stereo BT internet radio (by the way in asf/wma format) for 2 hours via 3g. At the end i still have 2 bars of battery (assuming battery was fully charged before). Absolutely IMPOSSIBLE to do this on iphone.
2. Watching 3 NOT converted movies of dvd resolution, divx, 1.4gb, 1h30min each and STILL 2 bars of battery (assuming battery was fully charged before). Absolutely IMPOSSIBLE to do this on iphone.
IMHO, a lot of the processor speed increases in recent phones are because Android's Java-like virtual machine setup is slower. Android phones operating at the same speeds as some Symbian phones (~400Mhz) are often noticeably slow, and a lot of the big MHz increases lately are in Android phones. Phones on Symbian, Maemo, and iPhone OS run native code and don't have to worry about bytecode translation at runtime, which means less work for the processor. Many were shocked when it was revealed the Nokia N8 "only" had a 680MHz processor (why not 1GHz? The Google Nexus One has 1GHz!), but Symbian doesn't NEED a 1GHz processor in order to run most applications at acceptable speed. Why put in something that is going to drain your battery faster if you don't need to?

Example? I don't se how Android's third party development language makes it any slower in actual use than a Symbian device. Rather on the contrary. Android apps are generally smaller in size than Symbian apps, they load up quickly and are much faster to install/uninstall. Ever actually used an Android device? Doesn't seem like you know what you're talking about to me.

Neither does Android. The 1GHz thing is mostly about marketing, comparable to the megapixel race. Besides, it's not just about clock speed. It's just as much about the architecture and GPU. Example: the Milestone (droid) running at 550MHz is in some cases faster than the Nexus One's 1GHz Snapdragon. Games that take advantage of the Milestone's superior GPU run significantly slower on the Nexus.The Milestone's TI OMAP 3430 CPU overclocked at 1GHz also runs better than the 1GHz Snapdragon processor. There are some tests done here - Google it. 😉
I'm a fairly new smartphone user (3 months). I own a Nokia N97. I feel that it is reasonable to expect my smartphone battery to last all day. I don't mind charging it every night. I do this with my previous Nokia phone (which by the way doesn't seem to be able to last 2 days without charging).
I do find that using GPS apps tend to drain my battery quite a bit. For that reason, I bought a car charger. I don't mind it that much since the car provides a source of power. What I do mind is when I use a poker timer application and the power runs out part way through our poker evening. I used a timer on my old time for our home games and never ran into power problems. I expect to be able to run my poker timer app on my smart phone and have it last the 4-5 hours.
The smartphone is a mobile device that can do many things. The more things it can do, the more it will be used while away from your primary charging location. I think that manufacturers need to ensure that their smart phones be able to last a full day with moderate to heavy use. If I have to worry about finding a place to charge my phone during the day, then the device no longer feels like a mobile device anymore.
I think as a smartphone, it's crap that manufacturers cannot include a larger capacity battery. If Nokia can include a 1500mAh battery for E72 (of course Nokia got it wrong for N97 and N97 mini), why can't others follow suit? Mind you, E72 last 2 days with heavy usage of calls, games, music, FM radio and data.
Having said that, buyers then need to be aware what they are letting themselves in for when they buy a smartphone. Big screens cannot sip battery like a E72. Do you need a 4" screen to sms and make a call?
For me, I carry an iPod Touch and E72. The former is for games and video but E72 is my communications hub for emails and sms and calls. And E72 is not too shabby as a music and games machine when the iPod battery is low. (By the way, why doesn't iPod Touch have a file manager?? I installed 2 office suites and I need to upload the same file TWICE for both suites to see the file!)
Ideally, a smartphone should have the ease of use of iPhone (with a file manager and task manager, please! Users are not that stupid!), screen size of HTC and the battery management of Symbian and E72.
Long buttery,I received a 2800mAh battery and new phone back to accommodate it, Just charging it as I type, and to be frank it makes the phone look horrendous, however if it lets me use the phone for a day or two without carrying a spare battery or charger, I think I can live with the bulk and weight. I'm hoping it will give me two days of heavy use and if it doesn't, the only thing I can think of is a very very very long usb charger cable, which somewhat defeats the concept of a mobile phone,after a some time buttery problem occur,change it.
Very nice article 😊
I ALMOST agree with you, though it's more on a personal note than general. I recently bought a 5230 (which has the same processor as the 5800), and I really REALLY wish 3D gaming was better. They run at 10-20 FPS. I wanted 30 ;_;
Oh well, it IS a phone after all, but more importantly, it's NOT a gaming device. For everything else, I'm quite happy. The battery lasts for a day and half in general (I browse the net for about 30mins a day on a 2G connection, play games for about an hour).
