My impressions about GS3 battery

I have bought GS3 2 days ago from Dubai the GS3 is amazing, this phone is the smoothest android phone I have ever used.
The only problem I have noticed with the battery it never reaches 100% it only reaches 99% when trying to get a full charge
So far I get with this battery nearly 8 hours and 30 mins to 9 hours with heavy usage, my phone is still unrooted so I didn't have a chance to try any juice defending apps.

I dont think anything is wrong with that....mw galaxy s doesnt reach 100% eighter...i think it has something to do with android protecting battery from overcharging

That isn't too impressive. However, you can expect the battery life to improve quite a lot after about 4-5 full charge cycles. Thanks for posting your experience

When I was on stock roms with gs1 I had the same problem with 99% but cm7 and cm9 goes to 100%

Yes indeed, batt stats plz

Without more stats 8hrs doesn't mean a lot..... 8hrs gaming would be impressive though

Thanks for sharing your experience. Out of all my experience i can tell after few charges you would get a better battery life, up to 15% increase.

guys dont forget,if you need better battery life your first charge cycle should be a complete one without any interruption.

for a full charge cycle do i have to discharge the battery to 0% or just 1-5%

should that be with the phone off as well? i have read that as well.
thanks for sharing. 8.30 hours of heavy use is respectable(if you can define heavy use it will be better though), but i had managed to get that with HOS on heavy use, even less so im confident it should be fine!
So confident i have already pre ordered a second battery as well! haha

I have been using the phone heavily since the past 12 hours which includes constant connection to 3g or wifi networks, app downloads, navigation for about half an hour, half hour of calls, 20+ texts, about an hour of streaming YouTube to my tv using twonky and I'm still at 35%.
And since the device is new so all my friends and colleagues have been checking out its sound, video and camera.
I haven't even been through my first full cycle yet and the results for me are pretty satisfactory so far.
Also it was connected to the car Bluetooth for about 45 mins and I had 15 mins of calls during that time.

Urban legend...
"It is important to condition (fully discharge and then fully charge) the battery every two to three weeks. Failure to do so may significantly shorten the battery's life (this does not apply to Li-Ion batteries, which do not require conditioning). To discharge, simply run your device under the battery's power until it shuts down or until you get a low battery warning. Then recharge the battery as instructed in your user's manual."

Moderate usage ...

Guys, the screen on time is the one we really need to see. It's the screen that really impacts the battery life on an amoled phones. Please try to include those in your screen shots.
Take this screen shot I just took from my GN for example. May look like great battery life but what you don't see is that the screen has only been on for 35 mins, so it's nothing at all special.

Anyone else getting ridiculously GOOD battery life

1 day 1 hour+ and it still was showing 100% battery life and discharging, with about 45 minutes of on screen time.
I thought the battery gauge/meter was frozen at 100% and was about to reboot it, but it finally dropped to 99%.
Granted it was idle a lot and I usually turn off wifi overnight, but still pretty impressive IMO.

Nope lol what was the 45 minutes of usage?

i took mine to my inlaws and used it for a chunk of the weekend and never charged it. I got home sunday evening and i still had 40%. But i am not running stock either... so that may be a difference.
Right now, I have been on battery for 1d 4h 4m 48s on battery and have 74% battery left

75% right now, I am at 1d 23h 14m 56s on battery with screen use at 1h 40m 24s, rooted but stock ROM.
at this rate, it would go 8 days with about 7 hours of screen time.
it never used to be this good. something is not right, lol.

Well tablets do tend to have good battery no cellular radio (wifi only) so no texting or calls, my ipad last a week without charged over 10 hours screen time. Now my nexus 7 I'd taking the hit because is new, I'm not getting rid of the ipad it has a low good games for my son and movies as well, 16gb is no enough sometimes, so I just keep important apps for my n7 and ipad as a backup, I'm only taking n7 to work now I got wifi there and thetering so that helps

What's the longest screen-on time you've ever had?

Sometimes the problem with a big screen is that it can use up a lot of juice.
Even before I bought my Note I had heard of the rumours about really bad battery drainage that came with ics.
Well today, a Sunday (in Australia at least), rather than studying hard for my Maths test tomorrow I was on my phablet, watching youtube (a friend showed me this really awesome channel recently) videos, surfing the web and xda, whatever; pretty much the phone was hardly on idle/standby at all.
Except for when I had lunch in the middle.
Anyway, it was the best battery life I have ever had.
Here are some screenshots:

In fact the battery life was so incredibly good, I thought I was using one of my two Anker 2700mAh batteries and it wasn't until I took off the battery cover to change the battery did I realise that I was actually using a stock Samsung 2500mAh battery.
Typically, when I'm at school and the phone is just idle in my pocket all day, I get around 3 hours screen on time with the stock battery, and 4 hours with the Anker batteries.
So this 5 and a half hours with little idle time is absolutely mind blowing for me (hence why i felt the need to post about it on xda).
Without needing to charge it, what is the longest screen-on time you've had with your 5.3 inch beast?

4.5~5 hours, stock gb, with some crap freezed (unasomething, samsung push,and some other) and k2-12 speedmod kernel on lb1(regional/device dependant) modem. Just browsing and tapatalk on dark theme.
But, this should be in q&a section

ics with cf-root.

rom was xme latest gb, but had simmilar results on latest dbt,and open europe latest gb rom
edit I posted not for discussion, but for means to replicate, should someone want to
ps, result only thought ultra clean install with fresh install of everything, no restore of backups and such
ps2 learned hardway, make efs backup and safe across multiple locations so you have way back, as flashing different csc roms can damage efs easily and before you know it no service. Hacking your way back is costly, so backup efs and dont make same mistake as me.

Well I've never gotten anything.

On stock ics 4.0.4 using a stock battery, min brightness, mobile network 3g
currently 4hrs 14 mins with 48% battery left
total time on battery is 7hrs 55mins 47 secs

10 hrs while reading e-book on aldiko
with grey text on black background
7% juice left
3g and phone on

Flight from Atlanta to Orange county Ca. 3.7 hours. Plenty left. I never use the device screen on for hours on end unless couped up in a plane.

Battery lies.

OK so I have had this phone two days now and noticed an oddity. I had about 43% battle according to the phone. I rebooted and then jumped down to 20% or so. Anyone else see this.

I think all Android users faced some issues with battery status..
Ex. When the phone charged 80% if restart it the battery might decrease by 5% each time... while when it's less than 10% each time the battery decrease from 1-2% max ! ... that's really not reasonable
In addition, when i charge my phone 8 hour the battery would stay 17 hour.. while if i change it until it's got 100% charged "according to battery status" it wouldn't stay on more than 10 hours!!! Wipping battery and other solutions also didn't help by the way !!!!

I will try that

I had a similar problem and never solved it. My battery typically lasts 32 hours new. After a few weeks it went to 16. Frustrated I let it "die" to find that it actually continued to run for 16 additional hours literally at 0%.
Unplugging the battery fixed it for that current charge cycle but upon recharging it went back to its old ways.
I eventually went through the trouble to purchase an OEM replacement and further open up my Razr M to replace. Things were great for another couple of weeks until the same exact problem happened again.
Frustrated I go back and forth between my Inc 4g and my Razr M depending on if I need a reliable battery read (traveling, etc). I like the Razr M so much I might just buy another and hope it doesn't crap out like this one, but then again there is probably a new season of Droid devices coming in a few months.

have you tried one of those battery calibration apps? they require root though.
as for me, my battery yesterday showed 34% while in the system. but then when I booted in TWRP recovery, it said my battery was at 22%.

Can't you wipe battery stats in cwm too? That could help...

Hi all!
I just bought my g2 for a week, after flashed slimkat, I found that the battery stay at 100% for quite long time. In my case, at least 3.5h, include 12 minutes screen on, 3 minute phone call.

Yeah. Its been estimated that the 100% to 99% is actually about 5 percent. I think I had something like 30 minutes of screen time before I went to 99 percent. the standby time can be quite hilarious. I wish I still had screenshots, but I had one of my phone sitting for about 9 hours 100 percent the whole time . As soon as it drops to 99 percent my estimated time was like 980 hours lol

Yeah, this.. Staying at "100%" is completely artificial. As soon as you hit 99.4% it should show 99%, but I imagine that leads people to think the battery is depleting fast, so they've done something to make it show 100% longer.
What's interesting to me is that it's the same on custom ROMs as well, so it's not something the ROM itself is doing.

I think it's the battery technology that does that. Android seems to be written for different battery tech.
Also I don't like the flexible metering. Play for hours, set it aside a few minutes and battery percentage increases.
I hate it in cars also, I want a meter to show how much I got exactly lol.

On CM11 mine will usually adjust down to 99% fairly quickly. If I wake up and start browsing after taking it off the charger, the circle will get a notch out of it usually within about 5-10 minutes.

Basically leaving it charging despite having reached 100% so it trickle charges for an extra hour. It seems to have improved the battery life.
