Help Will the battery last?

[razorgamez]

Going on a trip to boston on bus. Tak sabout 8-10 hours. Will the galaxy play music for that long?

 

[informale]

probably yes, esp. if you turn off autosync, background data and internet connection.

Don't see why not. If your worried about battery life then install SetCPU and restrict it to ~200MHz max. The experience will be shit, the music will play fine and the battery will last


Or, configure the CPU to only scale to higher clocks when its under 95% load to clock to the next stage. (122 -> 2xx -> 3xx -> 4xx -> 5xx MHz)

Honestly I'd be amazed. Just based on experience, not tried shutting everything off for any length of time.

 

[razorgamez]

thanks for the reply. I am also thinking of putting galaxo on it....a) is galaxo that much more amazing than the 1.5 cupcake installed? and b) will the remarks about the battery life be the same on galaxo?

You have a lot more control over your phone with root. That is the main advantage imo.

My old non-smartphone could not play music for 8 hours straight. Just bring a spare battery and pop it in of the the first one dies. Android phones have that feature, while certain competitors do not.

certain competitors do not need two batteries to get through the day

iPhone 3GS Audio playback: Up to 30 hours...

hehe

I'd love to see an iPhone last 30 hours while powered on. I'm sure caveats apply to that condition, along the lines of being powered up in Airplane mode etc.

My i7500 lasted 5 hours of constant internet use plus a 2 hour car ride each way (in which it just sat in my pocket, using 2G only for its normal background stuff but I wasnt touching it) and still made it home so I'm sure it will last 8-10 hours playing music as long as you arent constantly turning the screen on to fiddle

You could also try switching Airplane mode if you arent requiring its services as a phone during that time, or if you are then disable data connection (via APNDroid), turn off autosync, background data, wifi and GPS.

Of course there are, but I'm pretty sure it is achievable.

 

[mrqs]

i'm pretty sure it's also achievable on a galaxy if you use cheats like airplane mode

If I disable data conn with APNDroid is autosync and background data also off? i have also turned off wifi and gps.

yes

well, no, they are "on", but they have no data connection to use, so in practice they are "off" (and not eating battery)

not true. they are eating battery.

idle phone in airplane mode with AS/BD on - sleep 3%
idle phone in airplane mode with AS/BD off - sleep 0.8-1.2%

 

[mrqs]

that's weird - hopefully google has fixed that in

 

[informale]

you're sure it was as/bd interrupting the sleep?

*edit* now that i think about it, it kinda makes sense - they have to keep checking if the data connection has become available
still, would be better if the event of a data connection becoming available sent that info to the as/bd module, rather than it periodically checking for it

I thought so too, but a simple experiment proved me wrong. I too think it makes no sense. I would understand if some badly written app was desperately trying to access the Internet, but it is weird OS connectivirty services are runing, while the system 'knows' there is no connection.
