SGS2 Weaknesses - Are they corrected in SGS3? - Galaxy S III Q&A, Help & Troubleshooting

1) Wake up lag - On SGS2, when you press home button or power button to wake the device up, you wait 1 to 2 seconds before you see the screen. How is it on SGS3?
2) Home button lag - When you press the home button, does it react instantly, or does it wait for a double click and waste time?
3) High Android OS use with some ADSL routers, especially D-Link based ones. This made me keep wifi off all the time. I hope it's corrected on SGS3.
4) Very long charging time, espeically from USB - On SGS2 with even a relatively small 1650 mah battery, it takes more than 3 hours to charge the device on USB. I wonder how fast it is with 2100 mah on SGS3. If it takes 5 hours, forget it.

The charging wont change.. It's a limitation of USB rather than the phone.. A USB2 port has a max rating of 500ma
Some sgs2 roms had the option to force the phone to try and charge at 1amp when connected to USB.. Some machines it worked on, others it didnt and crapped out the port.

wake up lag fixed basing on a post by user who already has that phone.

It will probably take around 4-5 hours to charge on USB as the phones battery is larger.

Earlier reviews state about 3 hours. Yea, I can't find any links now but I remember reading that.

Oh fair enough I hadn't read any which mentioned charging through a laptop.

The battery of the Galaxy Note (2500ma) takes around 6 hours to charge via usb, so expect 4 or 5 hours for the S3

LMFAO..from where did you get that.. galaxy note takes only 3hrs 15mins to charge from o to 100..

My charging time about 3.5 - 4 hours from 1% to 100%. If you start charging from 15% you will spend 3 - 3.5 hours
I'm charging my S3. 50% in 1 hour this time . Super charging

You guys reliaze we are talking about charging from usb, through a computer right?
USB2 has a maxium output of 500mA so it will take atleast 4.2 hours to charge a 2100mAh battery... and of course even more when it's powered on.

Code:
1) Wake up lag - On SGS2, when you press home button or power button to wake the device up, you wait 1 to 2 seconds before you see the screen. How is it on SGS3?
Sometimes it's instant, sometimes (after not using it for a while) it takes a second to light up the screen.
Code:
2) Home button lag - When you press the home button, does it react instantly, or does it wait for a double click and waste time?
There is a lag of about 0.5 sec.
Code:
3) High Android OS use with some ADSL routers, especially D-Link based ones. This made me keep wifi off all the time. I hope it's corrected on SGS3.
I'm connected to a AVM Fritz!Box 7170. My current battery stats. This was heavy use (playing games for an hour, watching two hours of HD video, surfing the web for another two hours while listening to music).

Charging via AC was ~3 hours, via USB it's ~5 hours.

to op who asked about wakeup lag.
this vid shows no wakeup lag.
aren't lags like that supposed to be only on those who underclock to very very low speeds during sleep or deep sleep thus on wake-up those who set it to incremental step up in speeds experience this kind of lag?

Nope, on SGS2, you get wake up lag with all voltages and all speed settings. It's the time the kernel wakes the modem up and it can't be changed because it's designed that way.
The video is interesting, but I'm not sure it gives an idea about wake up lag. In the beginning, the guy doesn't give the phone enough time to go to deep sleep, so it doesn't count. In 2:22, he turns off the phone with video playing in the background, so the phone doesn't sleep either.
I wish there would be a video where someone wakes the phone from deep sleep and we can see if there is a lag or not. Most weaknesses corrected by flashing CM9 or AOKP, but this one is a hardware problem, and I'm never buying another phone with this kind of lag.

Can't link to the video (tapatalk blah too lazy blah blah) but I do remember seeing one of the reviews and the device DID have the same damn lag... I died a little inside when I saw screen turning on a bit more than 1 sec after the guy pressed the power button.

I'm finding USB charger on my S3 very quick compared to the S2.
However, there is definite home button lag. It's better now that I've disabled the double home button tap for S Voice (homescreen shortcut instead) but there's still a lag. It could be Apex rather than the phone.
All said, battery life is excellent. FAR better than the S2. S2 got me through about 8 hours. S3, with similar use, is about 60% after those same 8 hours.
The S3 seems slower to me. I'm looking forward to having the kernel, rom yada yada mucked around with!

I got a little starting lag. It's not that bad but may reach up to one sec.

flyer power down and power on

hello all
just gost my flyer and its awesome I thought the 7inch factor would suck but quite the opposite. it is very fast.
I shut it down and shut it off constanly because its comes back on so fast is there is problem with that, hardware wise would I be damaging anything? just curious I guess
thanks in advance
Sent from my HTC Vision using XDA App
How about leaving the flyer in sleep/standby mode?
For this I use Screen Off FX available on the market for free.
Clearly, it depends on how many times in a day, and how gentle or otherwise you shut off and turn on the device. Wear and tear on the power button will happen sooner on those devices that are frequently played with in this way.
Is there any reason why you shut off your device often in a day?
Are you powering off or putting it to sleep mode? You can also look into the screen time-out period.
I feel as if Im using it like my netbook have it on for what I need then completely shutting it down to conserve battery life ie I use it in the morning and then head to work for a few hours so its shut down then come home to use it and then shut it down again before I sleep, but i guess no other reason for me doing it other than trying to conserve battery life. I was thinking it comes on so fast why not turn it off when not in use to conserve battery
Battery life on the device is not bad. It easily lasts an entire day... That's with WiFi on and push Exchange mail.
If you want even better battery life, turn on airplane mode also.

You should be able to get a whole days use and change with a full charge. The only time when you might notice heavier battery usage is when you use the pen. With 1-2 hrs of pen use, coupled with push and web surfing, I can still squeek by for the day. So use it and enjoy
HTC Flyer power down problem
Can't turn on HTC Flyer after power down during 10h ... power button is green after charge but device doesn't start.
Any ideas?
I would recommend to use the built in standby function, under settings/power you can select a time frame in which the device will turn off all radios while screen is off. But i do not think that this is necessary. I am just using this during nighttime. I can give you an inside view of my Flyers working day:
0530 disconnect from power supply
10-15 minutes surfing over WLAN
0630 in office surfing HSDPA until 1200
1200 Connecting the power cord with my laptop (charging over normal USB is slower than over power supply)
1530 disconnect from laptop with roundabout 50% Power
1600 arriving at home and start surfing and sometimes watching a tv show episode
2330 connecting the Flyer with its power supply. Power level is ~25%
If you do not have the time to surf or otherwise use the Flyer over the day for more than 8 hours i would guess you will come home with 10-15% power left.
Not to forget, i am using a lot of social and news apps, games and checking my 3 mail accounts automatically hourwise.

[Q] Rezound Battery Usage concern?

I just received my Rezound new yesterday, downloaded some apps from the market, and set everything up for normal use today. I got it off the charger this morning around 7:30am at 100% and its dead at 4:30pm. I would consider my use light today as I only used the web for maybe 10 minutes. I mostly did things like add contact shortcuts to my home screens and move icons around, and download maybe 2 new apps.
I came from a Droid 2 which got pretty awesome battery life running Liberty 3 and I'm wondering if my usage time is normal.
Total Time 8h 22m 33s
Display 80% (Time on 2h 45m)
Call Stand 5%
Phone Idle (Time on 5h 37m)
Android System 3%
Dolphin Browser 2%
Android OS 2%
Wi-Fi 2% (Time on 1h 38m)(I don't believe I was connected to any networks though)
Drop box 2%
The screen is what kills it along with LTE. If your screen was on for 2:45 that is why. The display sucks battery on this phone.
Thanks for the reply, I figured that was the case, but I still thought I would have gotten a little longer. I hope a custom ROM will help some with the battery life.
I am on stock rooted and don't really have battery issues. Typically I get 12-14 hours which by then I have easy access to power. If it is going to be a long day, I use the extended battery. It is not uncommon to still have charge left going into late at night.
I have the screen less than a third of the way on the selector and have Auto brightness turned off. Screen timeout is set to 1m but when I set the phone down, I have a widget called ScreenOff that I click to blank the screen. Primary reason for doing that is so I don't accidentally enter some app, but a secondary is that it turns off the screen before it would normally timeout.
When I am at home or at work, I use WiFi almost 100% of the time which due to strong WiFi signals there, (for me) uses less battery power than LTE.
Otherwise, I have LTE on.
Right now today, I am about 50% with 9h 12m of use. I fully charge nightly with the AC charger on my night stand so when I get up it is 100%.
I have an extended battery, but normally use the stock battery unless I know I am going to be away from the office for long periods of time.
I am not much of a game player, but I do watch short videos from time to time. I have streamed music, but don't normally. I get 10-20 calls a day typically and use my browser on a regular basis (reddit as well).
The camera is Awesome!
Unless your display was on max brightness and you were streaming HD movies. That's bad battery life. I get 2 times that even with autobrightness, maybe your battery isn't broken in yet
A good measure is 30minutes display time per 10%, and 1% per hour with 3G and normal sync scheduling... If your apps sync ever 15 minutes that will kill it, and 4G should kill it a little more than just 3G... Minor fluctuations are still OK, but you shouldn't have 15 minutes per 10% unless everything is basically on full blast
My battery life using the setup in my sig is usually very good.
I can easily make it through a normal workday listening to mp3s from my card/texting etc using the standard battery. My screen is set to 30%, screen timeout to 30 seconds.
I do like to stream audio however using iheart radio or Sirius radio online. If I do that, I'm lucky if I make it 4 hours on the standard battery (without ever turning the screen on) When I am going to do that, I use the extended battery and keep a 2nd one in my pocket. I have two external chargers I use so I always have spare fully charged batts.
I actually prefer the feel/weight of the phone with the extended battery and the HTCPedia cutout hard rubber case.. That gives me a better grip on the phone and I barely notice the weight difference when it is in a Jean pocket.
I guess it just depends on the actual phone itself. My phone charges everynight. I pull it off the charger at 6 am and by 10am the battery is dead. I have 3 batterys, and a wall charger that I carry around. I don't consider myself a heavy user either. No music or videos. Only text, gtalk, gmail and a phone phone calls that last a few min each. I only have google and exchage set to push. My 2 yahoo accts sync every 4 hours. I do have fecebook as well. Screen is very dim. This was all using rooted cleanrom.
I am now back to bone stock, with a CLNR phone that just arrived yesterday (due to connection problems with my computer) So maybe a stock rom unrooted will make a difference. Heres hoping!
Sad.....great phone, I love it!

This. I was playing "draw something " with friends today at work and even with a fully charged extended battery it only lasted about 3.5 hours with the backlight at 100% and oc'd to 1.7 GHz. But that was constant usage for those three hours.

Diff. Roms equal diff results for me. All of the ICS roms I've tried all keep my phone up time and awake time the same. Is anyone else having this issue? Due to this, I typically end up getting around 5 hours of life even if I leave my phone off for the duration of that time. It's annoying because I really want to stay on ICS but get double the battery life out of the GB Roms.

On Scotts CleanRom 3.6, with fairly heavy usage (hour of solitaire, hour of browsing xda, texting, 30 minutes of phone calls) I can get about 10 hours before needing a charge again. Before I updated to 3.6, which has the 3.8v battery fix, I could only get about 5 or 6 hours of similar usage. I don't recall if prior versions had my awake and up times the same, but I haven't noticed it recently.

I take it you don't stream audio like I do??
I just got my Rezound yesterday, and have noticed a surprisingly poor battery life. I did all my setup yesterday, and fully charged the battery over night. After unplugging it this morning, I listened to music off the sd card for about 45 min, browsed the net for about another 45, then stopped using it for a while. I noticed the battery was about halfway through, so I plugged it in to my car charger and did some more Internet stuff. However, after checking the battery info, I realized that even plugged in to the car charger it was consuming more power than it was taking in. I finally had to turn it completely off and let it charge to get the battery from yellow back to green.
This is the same charger I used for my Droid X, so I know that it is working...

I've been running BAMF ICS v0.9 for a few days, and the other versions before that. I get 12-14 hours with 4G on, and 20-23 with 4G off....I keep the screen on 40% brightness
Watch your clock speeds if you are on ICS. They constantly Max out, both cores. That's where your battery life is going.
Sometimes data flickers for me on random days, that's the only thing that wears my battery down fast. But I can still go through the day have 40ish percent left. If it doesn't flicker I can go through through day with about 50% left. And if in on Wi-Fi most of the time I have nore than that left over. And that's with using the phone for a couple of hours with the display on.
Trying ineffabilis with DSBs 1.1.3 kernel and undervolt it some
for me, battery life killers can be streaming audio (sirius xm or espn radio) and definitely jelly wars. Phone will die on extended battery in about 4 hours of continuous play.
Otherwise, normal usage, I get 10-16 hours of use on my extended battery before swapping it out (use 2 extended batteries).
4g definitely runs the phone hotter than wifi (about 20 degrees hotter for me)
The only time my phone gets around 95 degrees is if it's on a charger and I'm watching a movie, and it takes about an hour for it to feel warm, which could even be caused from me holding it the whole time. 4G doesn't get my phone any hotter than 3G Or Wi-Fi. Guess every phone is different though. least we get signal xD

Battery problems

This is my 4th note. The 3 I had previously the battery lasted a long time. I kept the same battery from the first one in all three exchanges. I took the new battery for this fourth one. Could this battery be a bad one or should I return the phone again for a 5th time. I don't wanna take a chance getting a phone with the problems I had on the other 3.
Just looking for some opinions

Good Lord, 3 exchanges! Wow... try running the battery all the way dead where the phone shuts itself down, keep it on the charger and charge it overnight (or in the realm of 8 hours) while leaving it off and see if that makes a difference. I ran my batt that way once and I'm getting 18 or so hours per charge (depending on how much I play with it).

Reflash your modem, rom, and kernel. See if that helps
I only get about 3 hours of screen time myself. Seems normal for this phone. The huge screen eat up battery fast. Plus if your using LTE, so good bye to your battery.
I don't think you have a bad phone, That's just how it is in my opinion...
so whats your total at the end.. like say.. 5%..?
If you're getting about 3hrs screen time, I'd say you'd be on par with what I'm getting. Some days I can eek out close to 5 hours screen time, usually on the weekends when im at home and on WiFi.

I don't know why you guys are getting such horrible times. With regular use I'm getting an average of 8-10 hrs screen time, depending on what I'm doing. I'm running Saurom RCVI, with Da_g OC Kernel, and tweaked a few of the JKay settings. I recommend charging to 100%, wiping batter stats, and doing a power cycle on it. That's what I did after installing above Rom/Kernel, and battery went from from 4-5hrs to at a minimum 7hrs.

I would like to see a screen shot of that
Fighting battery problems here as well. I'd assume it was normal for this phone, except when I see people posting great times.
1 week old phone. Switched to Saurom yesterday to see if it's any better. Screen regularly at 5%. Usually on Wifi most of the day (and I'm not in an LTE market yet). I set all my synchs (rss, weather) to 4 hours. Others (Twitter) are manual. Only Exchange Email is push.
Using Cpusy & BetterBatteryStats to try to see what's going on. Could be a bad battery - could be that the number I'm seeing is wrong.
Anyway, I'm getting about a 7% drain an hour *with the phone off* ! I'm even rebooting as needed to make sure it's in deep sleep & not 384 (which is very, very annoying). Unplugging the phone @ 7am means a dead battery by 3pm. And if I'm using the phone, it's more like 12-15% an hour (min screen, reading a book). Been charging in the car and at work - whenever I can for now.
Going to try to run some tests on the new rom. Leave phone off for 30-60 minutes & track % loss. Then, maybe put it in airplane mode & try again.
Some weird ones I see to often - Adfree, Maps, Alarm Manager (which I understand can come from almost any of my apps). Oh - tried Juice Defender, no help there either (didn't make any difference at all)
Finally, in the car with Waze (gps), a Podcast Playing, and the screen cranked up for visibility - the car dock/charger keeps the phone about even. On my HD2, a drive to work would charge up like 20-30% of my phone.
Really, really hope I don't need to carry a 2nd battery for days when I can't keep the phone charging.

How often do you get exchange emails? I stopped using push exchange email as it was a huge drain on the battery with the volume of emails I get...
With this phone the screen draws some serious juice, so if your using you phone in the car with the screen on its using about 950mah of juice, so your car charger will likely only keep this phone from losing power, it may not gain any juice, and it may even loose juice depending on charger power and what the phone is doing currently.
This is also why most of us are seeing about 3 hours of screen on time, as while the screen is on its using probably 700-800mah of power. divide that by the 2500mah battery and you can see why...
You can try other programs to try and help with things like background data, undervolting, etc, but that's all going to have a small effect as the "problem" is the screen, its eats up most of your juice. If you want to save battery you need to go after the big thing, the screen, not the little things. However short of reducing the brightness there's not a ton you can do about the screen. It is a big screen, and it needs big power to drive it.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

I *think* (need to double check) that the charger is putting out 1A. Where did you get the 950m number from? Is there an appx. chart for different levels of screen brightness (how about 50% for example when in the car? oh - and how much lower is the 5% I use indoors?)
Agree, the #1 thing is the screen itself, which is why I get very confused when I have the large drain with the screen off.
I'll also have to try a test today where I turn on my podcast, but leave Waze off - and turn the screen off while it's charging in the car.

950mah is an educated guess. If you have root you can run this in a terminal to see how much power you car charger is giving the phone... (su first)
cat /sys/class/power_supply/battery/batt_current_adc
I usually get about 9100 for a result, which is 910.0 mah. and my phone will charge barely if I dont have gps going (screen on). if screen is on and gps is on the phone will slowly discharge, so that puts the phone power usage at about 900mah with screen on, so maybe 950 was too high of a guess. So when the phone screen is on, your using a ton of juice for such a small battery.
If I use just a podcast app and the screen is off the phone will charge much faster while in the car. If I have google maps running, it stays almost even...
You could even calculate your usage. She how many minutes your were driving with the screen off and the phone charging and note the amount of battery% gained in those minutes. You'd see a huge difference in charging times with the screen off. In my 50 minute commute to work, I gain about 20% battery charging with the screen off... With the screen on, I see almost nothing.
Seems like some days are better than others.

New Battery

So I started a new thread cos its kind of different to my other one. The last little niggle with my Prime seems to be the battery. I read the instructions for once and it said to charge it all up. So i charged it till it was green and then powered it up for the first time. So as the instructions say i need to break the battery in. At the moment i am getting about 5-6 hours. The pad is on balanced with auto brightness. Does this seem normal for new battery. I would hope to end up with 9-10 or are my expeditions too high?
From what I remember the instructions stated that for the first time you should leave the prime charging for 6 to 8 hours. I personally didn't follow this and I'm still getting pretty good battery life. My advice is to let the battery drain out and charge it to full again and leave it connected for at least a couple of hours. The battery should calibrate itself through a couple of charge/discharge cycles and get better over time. Forgot to add, I have my wifi set to turn off when screen goes off.
If you're on firmware .21 it may be due to wifi. Check your battery stats. I have great battery life but as soon as i turn wifi on and use it battery goes down waaay fast.
I hope the new firmware thats coming adresses that, because before .21 that wasnt the case.

Lol i was too eager and only charged my prime until it reached 100% at a mall. But i still have great batterdy life

People that didn't fully charge it up the first time for 6-8 hours, exactly what kind of life are you getting and could you please explain what things you are doing on it. I didn't charge it fully and it accidentally got turned on during its first charge.
Thanks,
If you are on .21 don't expect the battery to be near 8hrs while on wi-fi surfing/video/screen on/etc. I had it on .15 for 2-3 days while deciding if I wanted to root or not and it was near 8hrs wi-fi on. I'm also hoping for the next update to fix whatever they implemented in .21 that's causing a significant amount of drain.
I am on 4.0.3, is that the right one
Sorry, wi-fi is .22
Thr charging over night for 10 hours or whatever is nowadays just a Myth that came from the old NiCd batteries (It was true back in the day), new LiPo / NiMh batteries have no Memory Effect and the first charge is nowhere near as important as with old ones.
In fact is actually better not to stress the battery doing full discharges / charges cycles.
These batteries get to their full capacity after about 10 charging cycles.
So if you didnt not charge X hours for the first time, dont worry, yout battery ill work fine.
The only thing that should be pointed out is that if you use very often your battery, every 2 - 3 months is recommended to let the battery discharge to 0% and charge while off to 100%. If you dont use the battery often (always connected) then is better once every month. Thats to keep the internal chip from the battery calibrated.
Well atm i am draining it down to <10% then charging. Is it ok for these modern batteries to be left on charging past 100%?
Battery life still seems pretty poor after 3 0-100 ish charges. 1-2% seems to last less than 5 minutes when on the net on balanced mode and screen brightness mostly down.

Yes, once the batteries are at 100% they stop charging. You can have them 100000 hours connected.. and they wont go past 100%.
im on .21 and i get great battery life. i never cut my wifi off. its on 24/7. battery drainage will more so be dependent on display brightness and what you are doing. wifi is already a known, wifi on any device drains battery at a faster rate than wifi off. it takes power to make wifi work ya know..lol i can easily get 9-10hrs. + with my brightness set to less than 25% & wifi on all the time.
also the two biggest drainers, as far as programs go, is gaming and web surfing. especially web surfing and especially while using flash. since web browsing is very ram intensive. I've noticed some browsers drain battery faster than other. Meaning some browsers are more optimized than others when it comes to power consumption. This shouldn't be nothing new. Everyone's battery drainage will be different because people use their device in different ways.
we have an update about to hit us any moment or day now so don't get too stuck on battery drainage on .21. it'll be time to test how it is on newer firmware.

Web surfing and gaming and WiFi are 3 major things in this tablet, what should we use it for then??
here are some battery saving tips!

That's what I'm saying. Everyone web browsing and gaming is different. Some web pages people visit might be loaded with flash content vs. Someone who visits a site with less flash content. The one with the loaded flash content will drain or use more battery than the other one. Same with gaming. I might like to play Dead Space or Shadowgun and you like to play hang man or some other simple game. The battery will drain faster with me playing the 3d graphic intensive games vs. The person who is playing simple or less graphical intense games.
Wifi is a must have and no way around that if you want to web surf. The amount of screen brightness, 3D gaming, and web surfing will influence how fast your battery drains. Wifi drains battery but not at a faster rate than those other things listed.
I think some people here expect to have brightness up to the Max with super ips+ on, gaming and web surfing all day and expect to get 10+ hours out of it. Lol. Its not happening. There are easily things you can check for and change to make you have better battery life. -
-First one being not to use auto brightness and don't have brightness higher than 25%. That's if you so concerned about making the battery last long.
-Second thing you can do is go into settings and change screen off display settings. I have mines set to 30 or even 15 secs. That means once 15 secs. Or 30 secs. Pass and I haven't touched the screen, the screen will cut off. That's a huge battery saver right there. Because my screen isn't on as long when its not in use.
-Third would be to go into settings and lower the frequency of sync settings. I don't need my email syncing every 5mins. Or my Facebook syncing every 5 mins or etc.. cut them down to maybe every hrs, or every 12 hours, or once a day. The best would be to sync when you open up the app instead of it doing it automatically in the background. Completely cut off sync to apps you never use. Constantly having things sync in the background is a major battery drainer when the screen is on or even while device is sleeping. If you put device to sleep and its always waking up to sync data, don't be surprised if battery drains at a faster rate during sleep or when device is awake.
-Fourth, cut of unneccessary sounds. Do you really need the keyboard or screen presses to make a sound when you press it? If so, don't be surprised your battery draining faster.
-Fifth, cut off that stupid vibration motor. Do you really need your tablet to vibrate when ever you press something on the screen or keyboard? Do you really need it to vibrate when your gaming? If so, don't be surprised your battery is draining faster then. Because everytime that vibrate motor goes off, it drains battery.
SIXTH, you can go into settings and have wifi cut off when device is asleep. Or you can go into Asus customized settings and have it cut off network activities when the screen is off or device is asleep.
All very easy steps people can take. Same thing as in saving gas in a car. There's things you can do or not do to make it last longer.

Its Def the firmware Asus should fix it soon hopefully

It does seem to be getting better though. I have had it on for over a day now and it is at 50%. Probably had a good 3ish hours of actual use. During the breaking in of the battery stage is it better to let it drain then fully charge or charge whenever I can?

Well hopefully after a few charges I will make my way unto that region, I think it has climbed though to a closer to 6-6.5.

Batterylife comparison: Stock VS CM9 VS CM10

Hi all
This is my first post, so let's hope I've gotten it right and am abiding by all the rules and the n00b video. And yes I did search for a good 10 minutes about batterylife and battery before posting and didn't find anything relevant.
I've recently swapped over from Apple iPhone and I'm now very much enjoying being on Android. However batterylife is a big concern for me, as on iPhone I could go 2-3 days without charging and now I can barely make it home from work and I definately have to plug it in before dinner. And yes this is with me closing down applications, wifi when not used, bluetooth when not used, running latest kies released PHONE:LFB firmware and so on.
So my question is... how is your batterylife after having rooted and installed a custom rom? The one I'm thinking mostly about using is definately the new Preview 3 (or perhaps wait for 4 or 5) of CM10, that XpLoDWilD is working on. Does anyone have any experience with the batterylife before and after?
Thanks a lot for any help you can provide! :highfive:

That's very weird. Are you international or a US S3? I easily get 3 days battery, very easily. Perhaps try turning off useless stuff like bluetooth, gps, wifi, etc when you're not using them. Turn off push email and other useless crap. See how it goes then?
I still have the stock ROM, usually 3.5 days battery before it gets to 10% and i charge. I'm going to go to OMEGA rom soon though.
I have tried almost all custom roms out there. And I can easily say the battery life is not any better if not worse on custom roms.
Stick with the stock rom. I would however recommend flashing a custom kernel like speedmod or phenomenal. They definitely give you that extra juice you need at the end of the day. The idle time and screen time has increased for me 10 to 20 % compared to stock.

I'm using the international version. I did turn off bluetooth and wifi, but not gps. Will try that aswell. I have manuel mail check every 1 hour, but will try to set it to 4 hours.
However from what I read in the reviews on GSMarena and other sites, it's quite normal to only get 1 day worth of battery.
Description of a pretty basic day with the Galaxy S3:
I usually unplug mine at 6 am, with wifi and bluetooth off and screen always on auto brigthness. Then at 7 am i turn on bluetooth for my earphones and bike to the train station and browse the web and such for about 45 minutes in the train. When I arrive at work it's usually around 80% battery and I turn off bluetooth. Then I'm at work from 8 am to 4 pm and check mails, texts, calendar and possibly make 1 or 2 short phone calls. At 4 pm I think the battery is often around 40-50%. Then again on the ride home I use the same, so it's usually around 20-30% when I come home. I then usually turn on wifi and play a couple of games, or watch some Netflix on it while I'm doing some other stuff or attach it to my stereo and play so music from Spotify on it. At 6-7 pm it's usually beeping at the 5, 10 or 15% marker for more power and wants me to plug it in to a power source. If I try to wait till I go to bed, I usually end up having it automatically shut down from lack of power.
I'm wondering if this seems normal or if perhaps my battery is faulty. From the review at GSMarena it seems quite normal and that's just the way Android is. They even gave it a good battery rating inspite of saying that it would only last them a day.

Okay, thank you for your reply
it all depends on the usage i have an iphone 4 as well and i have to charge it by the end of the day (at 10pm). So it dpends on what you do with your phone if you use 3g all the time thats not gonna last long if you have syncing on all the time and gps that wont help...if you just let it idle then you can get 3 days uptime with maybe 1 hour screen time.

My basic day is charge the phone at around 8pm, unplug at 10pm. I never charge overnight it's pointless (not that i think it'll hurt it). Wake up battery is usually around 95% after my alarm goes off. Brightness is about 60%. I don't browse the web very much, and I don't play many games, let's say 1 hour of web and 1 hour of games/videos/music per day. Maybe 1 hour of maps too. Mostly though, I text message and phone call.
I don't think yours is faulty, i think it's quite normal, it seems like you're a heavy user, I'm a light user. If I used my phone as heavily as you did i'd be happy with 1 day of battery.
One day of charge (the battery being at 20-40% at the end of the day depending on the usage) is quite normal.
I've found CM9 with Siyah to give the best standby battery (1-2% drain per hour with 3G and Sync enabled) since it's very lightweight and has no battery-draining bloatware other than what you install.
CM10 is still too new and unfinished to be battery-friendly, it's not that bad though.
However sometimes it will chew the battery for no freaking reason (at least I cannot found any) and the CM9/CM10 stock kernel is not that battery-friendly on active usage. No Siyah yet =(

No way is that good man, that means that if you leave it on standby alone you lose 25% per day. 0.5% per hour would be good/normal IMO.
