Smartphone battery life
Hi all,
Does anyone know why these smartphones have such short battery lifes? I don't mean the batteries wearing out early, but rather the fact that they run down so quickly. I have seen manufacturers' claims for some models that they retain a charge for up to 600 hours on standby, but then when you read the customer reviews and see so many users complain they have to recharge them every day! Are there any models that provide superior battery life, or can one configure them to consume less juice? Thanks, cc. |
600 hrs on standby is probably possible, at ideal operating temperature and with the phone never ringing and never being picked up, opened or turned "on", and with no backlight or kbd lights, and not connected to the internet, and not running any applications in the background, and very close to the nearest tower it connects to so as to use as little transmitting power as possible...
I'd wager the primary reason for early battery drainage is internet usage (which means images, image processing (scrolling, enlarging, etc..) and FLASH/Video (or it's smart-phone equivalent is). Video and graphics, just like with a PC or laptop, is going to suck the power the worst.. |
I see. So the key to getting good battery life is not to use the phone at all. Figures.

Pretty much.. Those specs given by many manufacturers of many products, do not reflect real-life situations or usage at all.
Consider CFL's (Compact Fluorescent Lights - or ANY fluorescent light for that matter) which boasts "10,000 hours lifespan". Well sure, the thing may turn on and emit light for 10,000 hours or more - but, by the time 3,000 or 5,000 hours has ticked by, the emitted light is so degraded, discolored & dim, that you pretty much need to replace the bulb anyways, making the 10,000 hour figure irrelevant. |
I am sure you are right. I just read elsewhere that it is now considered pretty meaningless to quote battery life figures for smartphones in the same context that is used for regular cellphones (standby and talktime) as they are extremely misleading.
Thanks for your thoughts. |

I'm not interested in social networking sites so those apps will be never be used. I shall be mainly using it for navigation (GPS) and checking websites at wireless access points. |

Just for clarity, this really is an older generation phone. The processor is slower and less efficient. There is a lot of math to be done in the mapping part.
It is not going to anywhere that extreme on a phone with a more efficient processor (higher clock rate, and hence throughput, at a similar level of consumption) but it is still going to be a relatively big consumer. I have, in the past, managed accidentally to leave the sat nav program running in the background and suddenly being shocked to see where the battery level had gone down to. |
Yes, I am agree that Smartphones's batteries has shortest life cycle.
I brought smart Phone last year only. I had to change battery last weak only. Because I had to charge a phone twice time a day. So I shown the phone to the person from whom I brought these phone he told me battery period i over you have to change it. |
I don't normally have such a problem with smartphone battery life but I always turn off the 'battery-intensive' features and turn them on when I need them etc
I only have to charge every 2/3 days with my Motorola Cliq :) Turning down screen brightness works wonders too, you can always turn it up :) |
To improve the life of the battery in the smartphones than use follow this :-
Use simple ringtones. Update your operating system Talk, don't e-mail Push less Turn off unused radios Watch the time Use a corded headset Use auto shut-off |
