Impressive battery life after juicedefender install

DeAtomizer said:

what phone do you have. Im using juicedefender on my Galaxy 2S and i get a days worth of normal use and thats it

I have an S2 as well, lasting full day of semi heavy use for me is a good deal as I charge it over night. My last phone would only last half a day even with no wifi on

Twinn any chance you can post your settings

Yep, you are all right. I'm on holiday right now so not using the phone that much.. even so.. 2 days in anyone's eyes is very good.

Yes my phone is rooted..

Not at all, if you dont use it at all and let it stand by, it will keep working for over a week.

Then again, whats the point? It's the screen that kills the battery in general. There are some apps that are power hungry of course.

The bottom line is, if you want to preserve the battery, dont use the phone.

I am sgtarting to get a bit frustrated with mine, the phone is fantastic, the battery is rubbish. It's a real design issue.

i dont see hows its the battery's fault?

a 4.3 super amoled screen which is EXTREMELY bright and vivid...its amazing.
thats your "design" issue.

put the same battery in a different phone and do you think it would do worse than its own battery???
its not the batterys fault at all. make the same phone with a smaller crap screen and it would last over a week easy. whilst your there, grab an iphone battery, put in this phone and watch the difference. none i expect.

yeah, 2 days is impressive no matter wat use.. my phone would die in a day just idling, i feel. lol. are u rooted?

No.. i just bought the Samsung galaxy s2 and i downloaded the juice app.. it slows down the scrolling and restarts the mobile when i tried opening my tom cat game.. it sucks.. when i uninstalled it the S2 got it's SOUL back!! ur a bunch of liars..

A smart phone sucks up battery. So just live with it. I don't think its actually the battery's fault other than that you can always use a larger capacity battery. But then its not gonna be as thin, or good looking.

Anyway, My SGS2 could probably last 2 days with light usage. Heck probably even 3. But truth is, I can live with charging every night. Last time I couldn't maintain 1 days usage but now no problem.

I maintain screen brightness at 25% and I off data (3G) unless I want to use it. Today, I had 30minutes of calls, using Go launcher Ex (which uses more battery than stock launcher), use the polaris office for 5 minutes, use Kobo to read a short story, browse the web, update apps through android market, and played angry birds for 1 hour (boring meeting and after noticing I had 67% battery left after 8 hours of usage).

Its now 13.5 hours and its down to 11% and I am charging it now.

Anyway, like I said I could get it to last 2 days with light to moderate usage, but I am more than willing to live with one day since its a SMARTPHONE. And I want to use it.

Didn't bother with juice defender or anything like that. I notice a big difference if you leave the 3G running, which you don't really need to. Just on it after a couple of hours or when you want to use it. It helps a lot. Now I get to play games too before the day is out .

Cheers

PS-Doubt most smartphones can actually last as long as the SGS2 with the same specs and usage. Don't forget, IPhone got a smaller screen.

I agree with Russell, for a phone with such an impressive screen and doing all the things it is capable of I am more than happy with the battery life I get. As long as I can get a days use out of it under heavy useage I am happy. The best I have managed so far is 3 days 16 hours and by that time it had gone down to 6%. That was on relatively light useage but even so thats' impressive for a modern day smartphone.

Unlike most phones it doesnt seem to drain power when it isn't in use.. for example after charging during the night I generally wake up to find it at 100% and unplug it. By the morning after a further 3+ hours it has remained steady at 100%. Currently 5 hours after unplugging the charger it is showing 99%.

Occassionally I will see the battery drop quite quickly but I have found that simply turning the phone off for a few minutes and then re-starting cures this. I can only assume that some app is stuck working in the background that the task manager isn't able to kill.

Clearly some people are having problems and I can only assume that they have dodgy batteries.

yes! once i come back on friday i need to get sober!

Off on the nerd twinn

That should say beers. Predictive text!

In reality, all talk about battery life extension is futile if you use any smart phone as it is intended to be used, ie web browsing, video watching, music listening, call making, texting, GPS, etc.

No matter if you use juice defender or not, when you use any smart phone to its full potential, you will see the battery drain before your eyes. At the end of the day the Galaxy S2 is a powerful little computer in your hand and current battery technology has unfortunately just not managed to catch up... yet!

Same as with a netbook and lap tops, you will see the battery drain as you use it!

So I dont see the point in comparing idle battery times?! There is also no point in complaining about battery life with the S2 because with mid-high usage, it drains as much as any other smart phone!

But i will agree that for those times when your phone is idle and screen is off, juice defender is definitely worth having. I recommend flight mode overnight!

I don't understand whenever someone mentions putting a phone on flight mode overnight to save battery. If you're going to sleep overnight, wouldn't you end up with more juice (100% to be exact) by plugging it in as opposed to entering flight mode? I also assume people sleep in rooms with outlets. Another benefit would be missed calls being logged.

I wouldn't like to leave my Phone plugged in most nights while i sleep, especially when it's not completely drained. It will take less than 3 hours to charge and the rest of the time it will be receiving power to which it cannot store or use. Repeatedly doing this can (not saying it definitely will) cause damage to the battery either by shortening workable use or cutting the amount of recharge cycles it can handle before it dies.

Interesting concept. I am a power user who streams feature films, surfs and games and absolutely must charge nightly, and it never occurred to me there are those who can get through the day with 80%+ juice. I always assumed that after our phones reached 100%, it somehow stopped charging to avoid damaging the battery, whereas before smart phones, you had to manually unplug chargers to avoid damaging the battery. I do notice a 100% icon on the top left after fully charging, and assume, much like a laptop with no battery inserted but plugged in, that the electricity from then on would safely only affect the phone and not the battery.

I have just bought a spare battery for the sgs2. But when I got it home, I realised that I have to put it in the phone to charge it.
Does anyone know if you can buy a battery charger separate from the phone. This would solve my problems as I am trying to alternate charging and use of these 2 batteries to extend battery life of both of these batteries. IMO I don't mind charging overnight, but I didn't know you could shorten battery life by leaving on charge overnight. As long as you let the battery discharge completely before recharging, I think is OK. It is difficult to let the battery completely discharge before reconnecting to charger. Also, I am not able to turn phone off whilst charging as I don't want to miss any calls as I am on 24 hr call.

Any separate battery chargers available?

I think anker do one, stick it in amazon

Am pretty new at all this...how do I install 'juice defender' ..I mean, step by step. Thanks

Really pisses me off people claiming days and days worth of battery - you look and they have not "used" the device.
No Internet or HD Games, no GPS apps or Media - just OS running.

Best you can get out of the S2 with proper use is a day. 4-10 hours heavy use (big games, gps navigation etc) if that.

Then move on to another topic - simple.

Your "proper use" will surely differ from mine, as will that of many others. Even with the same person, usage can very greatly depending on circumstance on a particular day. That's why people compare battery performance at idle - it limits other influences.

After all, nobody expects a smartphone to not use power when working. Minimising unnecessary use when not working is surely a good thing, however?
