Best Way to save i7500 battery

[kalanjeya]

Almost 8 hrs, i am seriously looking for the best way of utilising i7500 battery. I got confused with many advise....and setting.

Could anyone give a brief of what the setup do we have in samsung ??

 

[cbfatw]

which version you used?

as I knew, original version of my i7500 is IH8, the battery life of this version is very very short, lower than 10hours without any action like call,sms,internet, or market. after I changed version above IH8, like IL1, IL3, now I used JB2(Android 1.6(Donut)), it would be used about 2days with normal calling, and internet.

besides, try to disable Auto-sync function in Setting->Data synchronization. it would be save battery. you can enable sync function whan you really need.

 

[Mr.DNA]

Limiting the data connection to 2G only when I am not actively using the phone seems to be the biggest battery saving setting for me.

I want to chime in here. I tried the IH8 almost within hours of buying the phone. After 2 days, my conclusion, the battery life is horrible. I'm experimenting with JB2 now. At the moment, too early to tell if it's better or worse.

jb2 has good battery life

Too bad for all other problems JB2 got

Switch the phone off. Battery lasts for -weeks- then.

The phone does that, all by itself. When it's out of battery. In a sense, I guess it's conserving what little charge is remaining...

I had trouble odin'ing JB2. In fact, I think I nearly 'bricked' my phone. I'm on JC2 now.

Battery looks like it might last 24 hours now. -sigh- Still means I'll need to recharge my phone every night... oh well.

TBH, I've never had a problem with "having" to plug my phone in overnight. It's not like I'm going to be using it much when I'm asleep. It's part of my nightly ritual now; check the doors are locked, turn off the TV, plug the phone in... I've done it for years, long before getting the Galaxy.

What -is- an issue is when it doesn't last the day. If it keels over mid-afternoon then we're tending towards the realms of "not fit for purpose."

THIS, I agree with. About the rest, it's just that I've been spoiled with the battery of my old E71 and I miss it because of it.

- turn off 3G or turn off APN entirely when u don't need net (using APNdroid)
- turn off WiFi
- turn off GPS and detect by wireless networks, this also helps the no-sleep bug in JC versions

In 2 days my battery dropped ~20% (JC1).

MrBrdo,

I agree, but many people won't.

I don't use the phone as an e-mail device (mainly as an internet tablet, phone and calendar), but those people for whom this device is supposed to serve as an e-mail client, it is simply unacceptable to turn off APN.

I tended to give the same answer as you do, but I learned that there are people who expect to be online all day with their phone. And indeed, they should not be forced to charge during the day (0600 to 2200h should be possible on any device, with any usage pattern, imho)

If I keep my APN on, I might get there, but only barely; and I'm a light user hardly representative of the average smartphone addict.

I still think Google and all their OEMs should bundle their forces to do something about the battery usage of this OS (which I quite like, and which I want to hang around for a long, long time... but a prerequisite for that will be that it improves in some key areas...)

I'm no 'heavy' user by any standards, though, I agree with the sentiment you make. Battery life IS a perrequisite for a phone. (To an extent, I can tolerate low battery life in a laptop, but only to a degree)

Though, I doubt if Google can do anything about it. This looks more like a hardware issue to me. I mean, if it really were a software matter, android users of other phones should be complaining as well.

My 2 cents.

Do you think the Galaxy is any worse for battery life than any other Android phones? The answer is that it's not

Yeah, they're complaining too

You can charge it during the night, in your car, at the office... All touchscreen phones have low battery life, it's a technological limitation of the batteries.

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.

touch screens are eating more battery than normal ones, that's the connection.
What I meant to say was that battery technology did not evolve as fast as handheld technology, they need to improve the battery's energy density in order to provide decent battery life for modern devices.

it's not THAT bad, my battery lasts for 8 hours no matter how hard I try to drain it (3g, wi-fi, connected to IM server, twitter updating every 30 minutes etc.)

I have my old dumb phone for these cases but if I turn data connection off I think I can get 3 days of battery life on my Galaxy, you don't need real time email when your out in the nature, do you?

 

[porga]

Best way to preserve battery is to charge it full then turn off the phone.

That way, the battery can last for weeks, but bad thing is you cannot receive any calls...



Joke, ofcourse...

 

[carthesis]

I've found that the battery on the Galaxy has gotten better after a month or so of discharge/recharge cycles too. I can get 2 days of light/moderate use out of it.

It's still a bit galling this is all you get though, considering it sits in my pocket for a fair chunk of the day, with the screen off, doing not much. Especially when it's meant to have a class-leading batery and a low-power OLED screen... but that's a different discussion

 

[mrbrdo]

I did not state you need to turn off APN entierly. Depending on your preference, you can just switch to 2G only mode, which still improves battery life tremendously.

I totally agree with you. Yes, I suppose I could try 'running' from one power socket to the next, but it defeats the purpose of a 'mobile' phone.

In my opinion, a 'reasonable' battery life should be somewhere between 36 - 48 hours on full blast. i.e. with Wifi, 3G ... etc ON and IN-USE. Any dream phone out there with these specs ?

-sigh-

[MichaelW]

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.

 

[iNick]

I was wondering how long can your mobile last while listening to music.
The other day my phone used 45% of batery in app 60 min of listening to
music at highest volume and it was pretty warm which I think is wery strange
for operation like playing music.

Is this a firmware bug or the player is too heavy for the phone?

2-3 hours of music at 100% of battery

 

[Mr.DNA]

I usually listen to about an hour of music each way of commute, and if I am not using the phone for any other purpose the battery will only drop a few percent.
