Yeah I've been using Da_G's kernels here and there, but because I wasn't really using any of the features at the moment, I just flashed back to stock... And yeah, that's entirely possible.

Check your app/battery usage. You could have the same wifi sharing issue I had. Once you stop and freeze that, Qwik Wiz should go easy on your battery.

Also, I didn't do any kind of battery calibration either..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] imtiaz3:
I need to ask, that is unreal battery life. Can you tell me according to your phone after such usage, how long the display was on for. I believe it says in in the regular battery management under settings. Just want to know the impact of that since that seems to be the main thing killing me, which there isn't much I can do about.

LTE unofficially turned on in my area (LA). I'm at 28% right now after about 13 hrs with light usage.

I'm only getting one bar in my office, though. Maybe that's the culprit?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Chouie:
I average around 1hr/10% battery life on LTE & 1.5-2hr/10% battery life on wifi & mobile data turned off. Both these ratings were done with juice defender set at balance.

Prior to LTE & Data Plan, my phone would reach up 18-20hrs on one charge and this is without any data usages besides moderate wifi usage. Right now, 1hr 56m 36s later w/ (moderate use at home connected on Wifi & LTE) my battery life is at 83%. LTE connection at my house is weak tho, 3/5bars.

So if you ask me, the battery life in general really sucks. Tell me this isn't the average battery life.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] L1near:
I've been messing around with some themes etc, rebooted and recharged. Let me grab the numbers tomorrow once my battery is depleted. One thing though, I usually have my brightness turned way down...

Here's where I'm at right now:
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] aretzios:
There is nothing wrong with the battery. LTE is certainly hard on batteries, and this not only true for the Skyrocket. Unfortunately, there is no switch to turn it off. Maybe there would be in future versions of the firmware. But there are other solutions such as Powerskin for Skyrocket and extended batteries.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Chouie:
Thanks, i feel better about my battery life now. But how are some people getting 20+ hours on their phone?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] yaiiyaii:
those are people who lightly use it. I able to use mine for 2 days if I just do light texting and short phones calls

i don't have LTE in my area yet, BUT i can lose less than 10% an hour, or around 10% an hour while streaming pandora for the entire hour......and that includes quite a bit of turning the screen on to like/dislike and skip songs
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] imtiaz3:
On my S2 I LTE I am able to go settings -> wireless and network -> mobile networks -> network mode and switch off LTE from here, although I don't think this really affect the battery life too much
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] orlandoxpolice:
LTE is automatically off unless you are in an area where it detects that LTE is present.

This is weird. My battery drains about 10% per hour.

Unplugged my charger at 8am, dropped to 97% when I left the house, now I'm already down to 15% at 4:15pm. I only made a couple calls and texts. Played a few games of Words.

I have the GO Launcher and other GO apps installed. I also have a live wall paper. Do you guys think that's what's causing the fast drainage?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Chouie:
I think many ppl would agree that 10%/hour is average...unless u flash to a different Rom&kernel and use EDGE when u don't need the speed.

I have Juice Defenders installed and my wireless and wifi are turned off when not in use. And all the browsing/games were done over wifi.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Chouie:
Are u using a stock Rom? Any services pushing or fetching less then every hour? TPC actually made me realize that juice defending eats up quite a bit of battery by itself. I noticed on my phone, the app was eating 10% of my battery life. So the amount it was saving it was using up.

I bought 2 charger/battery kits and leave one at home and one at the office.

When im at the office with a fully charged battery, i usually have to swap out batteries around 3PM.

then that new battery will usually last me the rest of the night.

at all times i have a fully charged battery at home and at work. I have a car charger but it doesn't charge fast enough to really matter (but its good when im desperate)

also, having 3 batteries (one that came with my phone + 2 new ones) helps me out because sometimes i have to work these day / weekend long festivals with little access to an outlet... so in those cases i'll actually grab the two spares and take it with me
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Kohawk09:
I've got to say, battery life has been great for me. 45 min of phone calls, texting a few dozen messages, screen on over an hr, on edge for 11 hrs while at work. It's about on par with my previous device, which had amazing battery life. This was my worry when getting the phone, now - zero regrets.

This is the second day in a row with these kinds of numbers. Just got the device Friday evening and loving it.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mushlafa:
It seems like some people are getting really good battery performance while others are getting terrible performance. My phone used to drain about 3-4% per hour overnight when it was in standby. I used to get around 10-16 hours out of the phone and around 2 hours of display time.

Juice defender in my opinion greatly reduced the drain when the phone is in standby. It seems like most people are argueing the opposite. I now get around 1% per hour drain when in standby. I typically get just under 3 hours of display time, which ranges from 12 hours and 1.5 days depending on usage.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] s3v3n777:
I guess I'm one of the "great battery life" people. I absolutely love this phone. Left apple and came to android after owning 2 android tablets. One day I realized I was being dumb and wasting my time with apple. I sincerely wish people would snap out of it and realize what a great platform this can be. Granted, as we can see from this battery issue, it isn't without some quirks as it may be hit or miss and each phone behaves differently. I for one am infatuated with my white skyrocket and the sexy glow of the white buttons at the bottom. LOL my girlfriend will soon be jealous.

Anyways, I'm easily getting 20 hours and I use my phone a whole heck of a lot. So no complaints from me. And when I said use, I do mean heavy data, text, downloading videos and more. I do enable the power savings mode at 70% and use juice defender as well. Using the power saving mode helps because it shuts down things like GPS which I don't need all the time and cuts synching all the time (which I don't need).
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] godfirst:
Just would like to add if know one has touch on it in this thread. I've owned quite a few android devices and as seen with most users and the display containing the most percentage by the end of the day is not suppose to happen. The only way display is suppose to be as high as others have reported is if your using your phone nonstop for hours. I've been on the htc hero, evo, evo 3d, etc. and none of these phones had display with a high percentage unless I put in a lot of hours of playing with the phones non stop. I think that the skyrocket may have a bug which causes drastic drain on people phones. How is your display going to be at the top of the list with only 19 or so minutes used, unrealistic. Has to be a bug!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] s3v3n777:
Or you can say that those phones were poorly optimized and everything else hogged the crap out of the battery. See how a simple observation can be so easily flipped around? :)

In any regard, it makes sense that the screen should consume the most amount if energy as there are lights and all kinds of magical electrical things going on. Lol. The system should consume less battery as all that is required of it is simply processing. Granted, if you run the crap out if the system synching continuously and performing tasks then yes, the system should consume the most amount of juice. Personally, Im okay with the display consuming the most amount of power since I am on my phone with the screen on a lot. It looks deceptive in the graph because you're looking at a 20 hour graph and the bursts of screen time wont look like one huge chunk.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] superprelude:
After using few apps to monitor the battery usage, I found that leaving WIFI always on, turn off latitude, turn off auto locations for weather, I get easily 24 hours medium usage with games, video, news, web...

I get 1.9%/hr drain while sleeping.

I really can "not plug it in" for 24 hours and still wakes me up by alarm in the morning, but then really no point doing that because it won't get me to 36 hours, so I will still charge it at night.

- Location finding will kick the system out of sleep for few minutes every time.

- if set WIFI off after screen is off creates a schedule task to check every couple minutes which has a wakelock as well.

- No need any battery saving app.

- Any monitoring will just wake the CPU up from DEEP sleep. Deep sleep is everything, only uses <1% of battery/hr in deep sleep state.

- Stock rom, rooted to uninstall some absolutely useless crap. Don't even need any blah blah blah kernel diet rom.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] Kohawk09:
+1 on signing out of latitude - it's a battery hog. I did some tests on my previous device with it on vs off, averaged 15% better batter at the end of the day when I had it off. Think they'd have better battery management with it...

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] aspexil:
I was one of the great battery life people until Friday night. Out with friends my phone was burning hot. The battery usage didn't show anything other than the usual Android OS and Display in the#1 & #2 slots respectively. Battery usage kept going down and even this morning after unplugging from the charger was down to 59% in only 2 hours. Finally decided to factory reset as I didn't know what else to do. When I rebooted I was down to 10% so I let the phone use up the rest of the battery. Now I'm recharging. We'll see if I'm back to normal here in a few hours. I'm stock not rooted.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] s3v3n777:
Dang. Maybe there is an issue with that battery. I purchased a double pack of batteries from Amazon. They seem to be pretty decent so far. I mean they haven't erupted in my hand and they seem to last as long as the original battery. Being realistic, I don't expect them to hold their charge for as long as the original battery but you never know. Keep us informed about what happened with the battery. I'm wishing the best for ya.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] papertreeprophet:
I was really hoping I would be on the good end of the battery camp, but its looking like im not. I can often just see the percentage drop, almost use it to count seconds sometimes.

I have another battery coming from Amazon, if that solves it then I will take the old battery to AT&T and get a new one. Right now it will drop about 5% every 25-30, with zero use, and everything off.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] aspexil:
Which battery did you get?

The saga did not end well. The battery never charged up again. It stayed at 0%. I left the charger in and the phone shut off. Ended up taking the phone into the local ATT store on Monday and got it replaced as it wasn't clear if the problem was the charger, battery or circuitry in the phone.

Fingers crossed this phone works out better.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] papertreeprophet:
Tried bump charging and even did a factory reset. Still too early to tell, but it looks better than before, but still no where near what others are getting.

Edit: Just had a 5 minute phone call, and the phone got so hot I could barely hold it to my head. I'm starting to think I might need to pay a visit to the AT& T store.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] s3v3n777:
The two batteries are labeled as Hyperion batteries. Just do a quick search on Amazon for skyrocket battery and you'll see the picture of the set. I've been using the set for about a week now and haven't had any issues. The batteries seem to hold a charge as well as the original battery. For about $25 I can't complain. Again, I'm not seeing the excessive battery drain others have reported. I'm going about 20 hours on a charge with no problem. In fact, the last 30% it seems to do better on battery. I'm running the stock rom and deleted most of the att apps I could delete. I do use the power saving mode at 70% (I'm paranoid after the Nitro) and I actually stopped using juice defender and am still getting good battery. I'll be more than happy to answer any questions if you need help.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] guygreller:
I had battery issues since day one, i tried different kernels, wipes, freeze apps - nothing worked.

at night i used to lose 4% per hour no matter what the status was.

i finally installed this amazing ROM and since i did not look back - i lost 3% after 9 hours in deep sleep.

Well I assume that's one way of saying you have good battery life...however, why don't we try and help those that aren't having good battery life instead of rubbing it in their face?

Anyways, it seems there is a polarization that has occurred with this phone. Either you have great battery life or you have horrible battery life. I use my phone plenty and feel it gets good battery, perhaps there is some app working in the background for those having issues that's killing the battery.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] s3v3n777:
I saw you were trying to help at the end there but I came from a phone that was terrible on battery. We are talking 5 hours max and it was miserable. I used to feel tethered to my charger so I know how some of these people feel with bad batteries. To add insult to that my friends with IPhones would just laugh at my "hd" Android. Perhaps it was just flashbacks of bad times so I sympathize with these people here. My apologies if I came off holier than thou but I felt their frustration and pain once. No one should ever go through that.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] appdroid:
Depends on what you like.

IF you like stock look with less theme, and more battery on rooted plus modified ROM than get TPC V3.

If you prefer more themed and modded look than P4S's skyrocketeer is good.

If its about battery and that's all you care about than i would recommend getting tpc V3.

On the original phone I exchanged because the battery would not recharge the last look at battery usage was Display and Android OS as the top 2 apps. Nothing else even came close in usage.

I have to say the exchanged phone is working better (been almost a week now). Not seen any of the issues I had with the first Skyrocket like staying at 100% battery after charging. Fingers crossed I am good.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] s3v3n777:
Well I hope you don't have issues. Glad to see it worked out.

I have noticed something quirky occurring recently though. When I swap the batteries the battery does stay at 100% for a while then begins to drop normally. I know there was an issue with the battery registering 100% for people but theirs seemed to stay there...mine stays for a while then slowly drops normally after a good 20-30 minutes. I'm not complaining but it is weird as it never did that before. I'm just going to (optimistically) assume my batteries are that good. Don't crush my dreams people! Lol

I'm getting about 10-12 hours with fairly heavy usage. I used to get about 16-18 with the same usage patterns on my iphone 4. With that said, the 10-12 is sufficient for me and a fair trade for the performance & screen size. I had a quick stop on the Nitro HD and with the same usage pattern I was only getting 4hours. That's unacceptable.

I have been seeing this as well. Both in stock form and with ICS on it. The battery shows 100% for a very long time and then drops dramatically.

Once, I played Need For Speed Shift on it for hours before I rooted it. It showed 100% battery right up to the point where it said the battery was dead and shut itself down.

i don't even mind touchwiz as I've grown attached to the touchwiz widgets such as calendar widget.

i'm at 23% with moderate use 1 DAY and 6 hours of use so far. i'm going to run this to 0%

I leave Wifi on all the time and use LTE when im away from wifi and when ever wifi is around i connect but i never turn Wifi off. GPS same way its always on. BT is always off.

facebook, google plus, dropbox, and light gaming here and there. no movie streaming yet.

My battery is starting to just plain suck. I thought is was bad in a HSP+ area. Well over the weekend I traveled to KC and got to experience LTE. My battery only got worse. In three hours it dropped 75%. During that time I barely used the phone.

So I really need to look at what apps might be causing this.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] yozh:
Got my skyrocket on Saturday night, really just comparing to an iPhone 4S and all the iPhones that came before that.

Battery seems to be sucky at best so far, I do have lots of widget and things, but I`m testing to see if I`m fully will switch from iP4s....

My Screen usage shows 55 after about 6 hours on battery, I did put it on Auto and at one point in the train I put on 0% brightness. What setting do people here use with a good battery life?

At my job in NYC downtown Wall St area, I used to get terrable battery life on the iP4S due to signal issues ETC.. Now I get LTE and seems that battery still sucks. I have to do more testing....

I`m wondering if there is something wrong, or I just need to start over and clean the ROM a bit maybe use the super stock 2.3.6 ROM ?

Really like the phone and like that it actually works at my desk and I can use the internet while walking around here in downtown, but with this battery it will really be a pain...
