Best Way to save i7500 battery

[chronodekar]

wifi on and in use for 36-48 hours? Yeah right.

Lets be realistic here. Mine lasts me 36-48 hours with moderate usage, but I don't use wifi.

Weelll, ok, perhaps I went a bit overboard there, (no, I've not seen even a laptop do it).

But, compared to my old E71, the battery life on this one leaves much to be desired. However, the other features of the phone make up for it, so I'm keeping it.

to report on the battery life of the fimware JC4,

The battery now lasts a lot longer than the various firmwares i have used.
My usage includes 3hrs of Wifi, 3hrs+ of music, 10 calls < 3min(each), a few smses.
with my above usage, i could get about 35 hrs approx. of the battery bfore it required a recharge.

This seems much better than the previous firmwares that i have used.

Wall charging is faster than usb charging. Does usb or wall charging gives more battery backup?

My wife has an E71 and the battery life is fantastic compared to EVERY phone, so its a pretty high benchmark to compare against.

FWIW, her E71 with wifi on constantly could last as long as my Nokia 6230i (ie: pretty old-skool) which did nothing much more exciting than phone calls :\

It definately outlasts my i7500, especially with wifi on. If we leave both phones connected to our WAN and doing normal wifi actions like checking email every so often and the occasional facebook update mine is gone within the day, while hers will last 48 hours.

Yeah, that was one good thing about the E71 - outstanding battery life. Better than any phone in its generation or a few after it too... -sigh-

Wall charging is definitely faster than usb charging. . . However, i ve never noticed any difference in the battery backup (ie, if they are charged for exactly the same level. . . .)

turn off background data (if you do not use the auto sync facilities and only enable it when using the market

you will find that it will prolong bettery life by a huge amount

Well, you can't compare E71,E72 with I7500. As like the model number it has got big screen to drain your battery enough while operate.

the exterior design was top notch as well - looked and felt really nice

too bad about the whole symbian thing...

Cough cough cough! I'm sorry, but I have to object. If you more or less have to run from power outlet to power outlet, doesn't that take the "mobile" out of the phone? We expect reasonable battery life -- measured in days, not hours. Not all of us take the car to work, and not all of us work right next to a power outlet. And that's just work; how about a nice extended weekend out in nature?

I'll agree that modern phones tend to be more battery-hungry than older ones, and that modern phones tend to have touch screens ... but technically there's no connection between touch screens and batteries -- that's just comparing apples and oranges. More likely, the problem is that the devices require more hardware for the same experience; an interpreted OS platform demands a Gigahertz CPU, whereas an embedded real-time OS would run just fine on a measly 30 MHz.

Battery capacity did not increase as much as average power consumption. So it is only natural that battery life will be shit. Considering the devices do all they can to conserve power when they can, we have amazing battery lives (~2-2.5 days for me).

Now if the galaxy had a 3000+mAh battery in it, then we would be talking.


As a comparison:
My old P1i Sony Ericsson had a 1050mAh battery!! A 240MHz processor, small (and shitty compared to the galaxy) screen. And nothing special (UIQ 3 operating system though)

The galaxy has a two processors, one clocked at 500+Mhz, a much bigger and brighter screen, GPS, Compass, accelerometer a better operating system.
And yet, the battery is barely 1500mAh. One would expect it to be in the high 3000 mAhs if it followed the other hardware.

You know, I never thought of it this way. It makes a LOT of sense, now that you mention it. Any chance someone has an external add-on to improve battery? .. on second though, never mind. Just thinking of how ugly some of those made the Palm Pre, makes me jitter.

too bad about the whole symbian thing...

I've only ever owned 2 phones before the i7500... a Nokia 3310, then a Nokia 6230i. The reason I only ever owned 2? They worked perfectly, never broke, had great battery life and were as robust as a tank. The only reason I ever upgraded was to take advantage of higher res screens and more internet connectivity (which tbh, was pretty limited in the 6230i but still a step up from 'non existent' in the 3310).

The only reason I jumped ship to Android was because Nokia is STILL hanging onto that damn Symbian.... Urgh. Its a horrible operating system, with horrible apps that are horrible to code for. Why are they still making phones and infecting it with this crap? Hey, Nokia.... take your good, robust hardware and stick something useful on it! Look at the N900... Nokia hardware + a linux based OS and its made every halfway tech-savvy phone user in the world masturbate simultaneously. Then what did they do? Market the buggery out of their flagship "N97" which is infected with Symbian. Urghhhhhh.

Anyway. I digress.

really good way of putting things !!! I dont think that galaxy is the only android phone facing battery problem . is it ??

Nope, look at any of the other Android phone model forums, you'll see they're all getting around the same.

If thats the case then Android battery management is the actual problem . .

Does the iPhone get better battery life then?

 

[angeamon]

vent used an iphone . . so ve no idea abt iphone's battery life . . .

however, I just cant phantom the possibility of android loosing to iphone on any feature .!!!!

Well ! when i spoke abt android battery management, i was thinking of the infamous sleep bug that eats away the battery life . . . since the bug has noting to do wit battery management, maybe i was wrong in concluding that android has a battery management issues.

 

[theredkrawler]

I put my phone on 2G data only and its increased the battery life significantly. The speed reduction for most tasks isnt noticable (ie: facebook) and normal background tasks like email checking and receiving tweets are fine, but when browsing its worth flicking back to 3G to save frustration at load times.

The problem is putting powerful hardware with a weak battery.

 

[chronodekar]

For that matter, does anyone know ANY android phone that comes with a battery that can handle it's processor ?

-chronodekar

 

[mrqs]

they all "handle" their processor
battery tech as been practically standing still ever since they came up with li-ion and they've just been left in the dust by the brutal development speed of ic's

 

[MichaelW]

nano technology will start creeping into batteries but that'll mainly just massively decrease the time needed to recharge (less than 10 minutes to fully charge).

What we want are radioisotope batteries, I'd like my battery to last the life of the phone

<face-fault> Ok, what I meant was does anyone know an android phone that has a good battery? My definition of good means, really long lasting, despite what you run on the phone.

-chronodekar

 

[theredkrawler]

Isnt the Galaxys battery one of the biggest in its class? By 'class' I mean compared to similiar generation phones like the Magic and Hero.

EDIT: 1500mAh .vs. 1340mAh.... so yes, bigger. But hardly earth shatteringly bigger

No, there isn't one and there won't be until battery tech gets better. And when it does we will all have the possibility of awesome battery life (if you'll purchase the new batteries)
