Fed up with stock battery life

[yash777]

Got about 14 hours today with more than 6 hours of continuous wifi and 2 hours screen time with 12% remaining right now. Hope its consistent!

The. You ha e some back ground issues my friend. Take facebook for example. All those auto updates and push notifications will eat your battery. Live wall papers will eat your battery. Hi brightness will eat your battery. Weak cell signals will eat your battery.

I just have push notifications for fb. No live wallpaper. Auto brightness. I got 19 hours yesterday though with significant wi fi time

this time wifi was off. 3g data connection.5 email accounts,internet,text and phone. the big drop at the start was watching tvcatchup

 

[cyanogen-man]

sadly yes. The lte radio as fast and glorious as it is. Is like a v8 With a 12 gallon gas tank. Not gonna keep the motor running long.

GPS on?? That's a major power draw

Gps is not a major power draw.
Its a receiver. It doesn't transmit. It takes virtually zero power. Mine is never off.

Turning GPS off did help me with the Map draining power issue.

Ok see I rest my case. it is also a radio it sends data to ping off the satelite to get an accurate location. Ok do this go down the road with navigation, and no charger take a 20 minit ride. see how fast your battery takes a death plunge.

The gps does none of those things.
It's a receiver. It doesn't ping (what ever the hell that means).

It listens.

Wrong.

[gattzzz]

I have 21 mins of on screen time, 4 hours idle and I'm at 49%. The only thing I have synced is gmail and yahoo mail.

Your source is wrong.

First sentence in the second paragraph tip you off that this clown hasn't a single clue about how radio receivers work.

You don't POWER a receiver's antenna.

Got that? You just don't. It just sits there and quietly picks up the transmitted signal. The braces on your teeth pick up the signal just as effectively.

The math involved is trivial. The phone's main processor isn't even involved. It's all done in a tiny chip that does nothing else but listen for satellites, and spit out 3 numbers.

It takes almost no power. To obtain your position.

It takes more power to find your position with the gps turned off. Because then you have to have the main cpu wake up and try to triangulate its positive from cell towers which is actually a more difficult task.

So, here's your task list:
1) take a course on elementary radio principles of operation. Learn how receivers work. The Boy Scouts could probably help.

2) look up the model numbers of the GPS chipsets used in your phone. Google bill of materials for your phone.

3) download the spec sheet for that gps receiver, an read the power consumption figures.

4) do some basic math.

5) sit down and be amazed what a wonderful time we live in where someone can own a high tech piece of equipment like a cell phone, and earn enough money to pay for it without possessing even a single clue about how even the tiniest part of it works.

Right or wrong, this is a little snipey. At least the guy looked something up instead of just saying "Nu-uh" like some other forums I've been to...
That said you seem to know your stuff, but it seems like I have heard of a powered receiver before, but maybe I dreamed it.

Anyway, how would Airplane mode effect this? I have to put my phone in AP mode all the time because I work in a cave.
And wouldn't turning the GPS off keep the phone from searching for it's location? So there would not be a drain from searching by other means, if it's not searching anyway.

Did that make sense?

 

[icebike]

Airplane mode shuts down all the radios.
That saves lots of power, because it's the transmitters that take power.

If the radio can't hear the tower very well it cranks up its own transmitter power (and requests the tower to do the same).

Working in a cave, or far from the towers costs a lot of battery. Just driving through rural areas burns a lot of battery, because the phone is always carrying on a conversation with the towers.

If you have wifi in your cave the phone will switch to that and shut down the expensive cellular data radio, and just listen for calls on gsm. Alternatively you can switch to EDGE (on some phones) and save about 2/3rds the power that 3G uses.

If you only need to receive calls, just turn off cellular data in settings. There's a widget for that too.

Ok cool thanks.
I have the data off all the time. I only turn it on in the rare occurrence that I want to look something up and I'm not and work or home.
Even with the data off though, I do get a lot of battery loss. I think there is just enough of a signal for it to search and die and search and die.

There isn't a way to get calls over wi-fi is there? Bc that is on all the time for me, and works pretty well.

 

[icebike]

Yeah i get calls on wifi all the time.

I use Google voice, so when my phone is on airplane mode (every time I visit relatives in Canada), I turn wifi back on when at their house or in hotels.

Google voice rings my free Ipkall number which throws the call onto the net to a free SIP account, which ring Csipsimple running on my phone. All free. All easy.

Some of my accounts in Europe call me via SIP directly, for free

Yeah, snippy is a good word. But if you read his posts that's a frequent style of his. Getting "snippy" when you are challenged about something is a sure sign of an inferiority complex. Anyway, having your GPS on when it's not needed is an unnecessary battery drain. Unless the laws of energy conservation are suspended in an android phone the GPS system (antenna, chip, flux capacitor, whatever) consumes energy. People can argue about how much but it is an unnecessary drain. Even the little GPS notification symbol consumes energy.

 

[yash777]

I was looking up battery life issues due to poor mobile reception. I get 3 bars on my One X for 99% of the time on T-Mobile and I just looked up my network info and it says Signal strength is -91dBm and 11 asu. Can this be the reason my phone is struggling to last a day?

Edit: Its also fluctuating upto -99 dBm

 

[cyanogen-man]

Yes low signal makes the cell radio power up more to grab more signal. The better the signal the lower the power cunsumption. And on tmo?? You mite not be getting full signal due to their bands not exactly being the same. Get a t mobile device and test signal strength side by side.
