Column: Not so smartphone power

Which brings me to an interesting question......How does the samsung Note's battery life compare to the Iphone4's...?
Click to expand...

Should be better as it has a 2500 mah battery while the Iphone4's battery is 1432 mah. The Nexus Prime has a slightly larger battery and only did half as well in battery life in the review I read. I've posted the url before, I'll try find it when I'm on a pc/ tablet.
 
The thing that takes away battery life is when you enable packet data. Turn that off and I guarantee your battery will last for days. Only turn it on when you need it and rather use Wifi if you can.
 
If battery capacities cannot be improved charging times need to. I doubt we would mind too much if we could charge our batteries from 0-100% in around 30 minutes off of ac power supply.

The phone has the latest firmware installed, I think that manufactures have forgotten about Ohms Law - The law stating that the direct current flowing in a conductor is directly proportional to the potential difference between its ends. It is usually formulated as V = IR, where V is the potential difference, or voltage, I is the current, and R is the resistance of the conductor - and simply that, accordingly if Nokia or any other manufacter of smartphones do not correct this power problem then the phone model is a "Lemon" as the yanks say.

Yes, the latest firmware still has bugs... They haven't forgotten. It's just a little screw up. Some software is keeping the phone from going into sleep and thats what usually causes battery drain.
 
Okay, found it:

You just need to drop down to GSM (GPRS/Edge) instead of 3G. It is the 3G that does most of the battery chomping.
On Edge, I get through the whole day with moderate use and home in the evening with battery between 65 and 70%.
 
By controlling both the hardware and software, Apple are able to better manage the power consumption of their batteries - precisely the reason I chose the iPhone 4 over the various Android phones. And if that's not enough for the super user, options like the Mophie case (www.mophie.com) are available.

Those little things go for years how awesome would it be to buy a phone that you'ld be outdated before the battery was flat.

Smart phone me you need to smartmanage your phones. I got a car charger for emergency and when I using my phone as a GPS, USB charger at work to top it up while am at my desk then I make sure I don't charger it during the afternoon so when evening comes it can get a full charge over night. And that way I am never without my smartphone. :D

Man I hope they make a GSM version of the RAZR MAXX. It is the RAZR but a bit thicker and with a massive 3300mAH battery

This, was reading an engadget review on it and they did more than 2 days on it.

It's not just all about the battery! Battery tech has improved drastically over the past few years. I still remember having to carefully discharge the early Nokias which had NiCad. Then NiMH became mainstream and phones would last for days on end.

Now try and imagine what did those batteries back then have to power? A tiny black and white LCD, no GPRS, no MP3 player. My first colour phone was a Nokia 3510 and it's battery lasted only a day (as a result of heavy snake II playing, in COLOUR! Lol).

Now step forwards ~10 years and what do the latest LiPO/Li-ion batteries have to power? Massive 3-inch + Hi-Res brightly backlit screens, HSDPA, 1 Ghz + CPUs, 3D GPUs, WiFi, Bluetooth, video playback, music playback.... You get the picture!! So no, a comparison back to days of old is not substantiated.

Cellphone technology has just moved too fast for battery tech! Like it has been mentioned in this thread, phones like the iPhone last quite a bit longer than most other brands and I think this is purely because of well engineered circuitry.

My 1610 lasted about a week between charges, my 5110 lasted about the same, my talk radio lasted about a week between charges, even my k810i lasted around 4 days between charges.
 
The writer does not disclose which smartphone he uses, albeit he does mention his first smart phone. My guess would be that he is using an iPhone because he refers to the battery indicator turning red. What do you think?

My HTC Desire's indicator goes red as well.

Android also goes red. First yellow when getting low, then red.

GSM/EDGE also eats battery. Not as much as 3G but it does.
 
I cant honesty believe that one mans bitch about the battery life of his phone constitutes a quality frontpage article on my broadband.

Many people all over the world complain. If you feel like attacking mybb, you've chosen the wrong article to attack.
