Juice Defender - >3 days battery life

I installed Juice Defender (free version) and shockingly I am now getting at least 50% more battery life (I normally get around 1.5 days out of my SGS2).

I havent changed my usage style (games around 30 mins a day, WIFI/Data around 1hr a day, etc).

I originally tried Juice Defender back in November last year on my HTC Desire Z. It didnt seem to make much difference back then. But obviously it has improved vastly since then!

matt can you try this for everyone? i would be fascinated to see if you can get up to 8 hours.

Nothing improves my battery life, without compromising ultimate performance, though on the other hand I probably have one of the fastest phones in the and roundabouts.

Oh and I can already get 8 hours...just use the phone less. When the screen's off it runs at 200mhz max.

can i ask... are you saying you get 8 hours if your phone is off???

matt101101 / MOD  Sep. 27, 2011 at 19:17

Yeah, pretty much. Well "asleep", whatever the phone version of a laptop being asleep is officially called. I get about a week (bit less maybe) if I just leave it asleep, barely uses any power at all.

Turn the screen on and the beast awakens....and eats all the battery om-nom-nom-nom, hmmmm lithium-ion, yummy.

Just out of curiosity, what phone do you have Matt?

On my next charge I am gonna try Juice Defender with the phone maxed out (GPS/WIFI/BLUETOOH/DATA/Full brightness, etc.) to see how long the battery lasts.... 12hrs? 8hrs? 6, 3? Place your bets (sorry, no £5 Amazon voucher on offer here (_;)).

I have a Galaxy S2 with the CPU OC'd to 1.6ghz and the GPU OC'd to 400mhz, from the stock 267mhz (less well known than the stock CPU speed). I run that with everything (bar GPS), on all the time: 3G, Wi-Fi, Full brightness, most regular background syncing apps will allow, the full works basically and my battery lasts around 6 hours with my very heavy use. Down to about 3-4 streaming 1080p video.

Why do you it? Are you some sort of power junkie? :p

I bought the fastest phone available because I wanted speed (then tweaked it to my liking), if I cared about battery life, I'd go and buy a Nokia 3310 :p

Except you cant buy a Nokia 3310 (well not new anyway).

So anyway, with the phone tweaked out to the eyeballs (And as a result you getting pathetic battery life) is the phone serving its purpose? Yeah sure its faaaaast, but do you actually use it as a phone or is it a toy to play with on the side... whilst your Nokia 3310 does all the main tasks of calls and texts? (_;)

he doesnt use a 3310 for calls and texts... he overclocked the phone to the point it blew up ;)

matt101101 / MOD  Sep. 27, 2011 at 20:36

Well you know what I mean, I'd buy some cheap **** phone, the 3310 was the first one that came to mind :p.

Yes, my phone is serving it's purpose, which isn't a phone. I rarely make calls outside of my office so it's more for personal use, text messaging, facebook, twitter, email (though that is predominantly business emails). So it's more a toy than anything, I'm a self confessed tech geek, so the powerful processor and beautiful screen appealed to me :p.

I don't really have a 3310 for calls haha :D, I don't have a second phone at all, apart from my Virgin landline and my office landline, which is BT, I think (the IT dept. deal with that, so I'm not sure).

Treab, an OC'd what like 20mhz ;)?

Treab  Sep. 27, 2011 at 21:09

after knowing you for 20 mins i wouldnt put it past you bro ;)

matt101101 / MOD  Sep. 27, 2011 at 21:21

First phone I ever OC'd was a Desire :p. Before that I had an...erm....iPhone...*hides ashamedly*...which I hated so much I used it as little as possible. Before that I had feature phones, not OC'able :p!

Shuwaz, I'm currently using a BB Torch 9800 - a phone with a horrible reputation re. battery life. Some fiddling done, I now get 2 days out of the ****. 3 email accounts on push, posting here and on Twitter. Persistance pays :D
