Battery drains too quick - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hey guys,
I have had the skyrocket for a week now, my main issue with this phone is battery. I get up at 8 with 100% battery. By the time lunch time roles around i am at 68% with light usage.
Sw version: 2.3.6
Rooted using bloat free and have frozen all bloatware pretty much.
I use original battery charger.
I have yet to reset my phone to factory settings. Will that help?
What should my next step be?

this phone to be completely honest has had the best battery life i have ever seen on a phone so far( stock that is) i get a day and half if i use the stock rom and kernel.
when i use a Launcher (Go Launcher ) i notice a big drop and then on top of that im oc with da g's kernel and if i start the day with 100 percent at 7am i get home at 5pm with about 25 percent. with the stock i would make it home with about 50-45 percent easy.
not saying your wrong.....im sure there are variables at play here.

I also use stock launcher, and i have stock rom. I dont use it for multimedia at all.
Only thing i use throughout the day is gmail, exchange activesync, tweetdeck.
Ocassional text messaging and a call or two.

I loose about 8% an hour with no use.

Using the stock launcher and after manually killing most of the stock services (facebook, and a bunch of others) it consumes about 1% an hour with all the radios off. It actually consumes less than that during the night, about 2% in 8 hours.
Question: how did you root the phone? Did you use the long-winded ODIN method or did you find a one-click rooter?

Root your phone and remove all the crap bloatware and your batt life will improve 100%.. Juice Defender is good.. I get at least 15 hours on mine. with light/moderate use... text. surfing the net..etc...

How to save battery on nexus S

Hello there..
i just rooted my nexus S 9020T..i flashed CyanogenMod-7-08312011-NIGHTLY-NS,Build number GRJ90,Android version 2.3.5
my problem is the battery keep draining faster..
fully charged at 7.00AM..10% at 4.00PM
i using Juice defender ultimate (said longer my battery 1.5x)
please help me...
Juice defender is a waste IMO. You could try an undervolted kernel like matr1x or Trinity.
Sent from my Nexus S 4G using xda premium
I suggest teuv kernel by Trinity, best battery life I've seen.
The nexus is a battery hog, especially with all kinds of background apps people have like whatsapp and facebook. If you get Trinity, follow instructions and you wont news any outside monitoring app as the kernel is very good about ram and CPU allotment

There are numerous ways to increase battery life. Firstly, you(Android) do not need battery apps and task managers/killers.
Secondly, try this.

Flash through recovery. Make a backup first. Choose the correct kernel for your device. Disclaimer: I'm not responsible for your flashing mistakes.

any other tips how to save battery longer??
Any further tips after a new kernel and rom would be cutting on the use of the phone and are therefore meh. I want to use the phone, not use it less.
So Trinity is better than Netarchy???, what about Pete #5 which is built in Formels MIUI, so far this is the best Rom I have tried on my NS, stable and fast+good battery compared to the others, also I have my phone OC at 1.2G via Setcpu.
Set wifi sleep policy to never.
Turn off auto brightness
Turn off sync and just refresh your gmail manually when you need to and refresh your contacts from time to time. You still get app updates from the market with sync turned off.
Go through all your apps that update regularly (facespace, twitter etc.) and reduce the sync frequency to something that is acceptable for you. I don't need my twitter updating every 15 minutes and can just manually sync whenever I want.
EDIT: Turn off NFC.
... and buy one or two of these: http://www.amazon.com/Samsung-1440m...TUEW/ref=sr_1_1?ie=UTF8&qid=1316132022&sr=8-1
Make sure to condition them properly - it really makes a difference.
Wifi Sleep Policy to never fixed alot of my battery issues
Turning off NFC will do nothing as NFC does only consume power (like GPS) when used.

PROTIP: Stop using the phone so much. None of these tips are going to do squat if you're using the screen and wifi/3G all day.
Trust me on this. I easily get 12+ hours of use with battery to spare (usually around 30-40%) with the following usage:
NOTE: Matr1x Kernel with the stock undervolting settings, and TSM Pool Party ROM running on top.
The screen is on (a little over 1/4 brightness) with wifi/3g blasting, surfing bright white web pages for about 2-3 hours total. I may play 30 minutes of Furious Neornithes D), screw around on the market for a few minutes, check FB updates, etc. I also probably take/make about 10 short phone calls and send/receive about 50 texts. The remaining time, the phone sits in standby.
Not bad, considering the phone is beefier than most home computers from 10 years ago. Also worth noting: The battery scale isn't the most accurate thing in the world. Battery percentage drops off sharply up until about 60%, where it seems to level off.
So what's the best kernel to use???, Trinity or Trinity UV?, Netarchy?, Matrix?, is not only about the battery but also stability, doesn't matter if u can make ur phone last forever if u can't use BT while browsing cause the thing crashes so u either have to use one or the other.
As this is the save battery thread, there's only one answer: lowest voltage trinity kernel.

Battery Life

Have one of these, rooted, stock rom on Rogers (LTE).
The battery life seems inconsistent... Some days it seems fine but days like today with 11 hours off the charger, with the two highest battery culprits being android OS (46%) and android system (16%) the battery life is already at 26%.
Other days when its on my desk it uses nowhere near as much...

You talking about the TMo version? I did a search and I cant find a Skyrocket or Rogers version of a BeastMOD ROM.
BTW I get have been getting 34-37 hrs @ 20-15% on the BoneSTOCKeteer-v1.0 ROM with med to light use. Your mileage may vary, but stock ROM only lasted a day with the same use.
edit: the more you play with/use your phone the faster the battery is going to peter out no matter the ROM
I noticed that wifi has a big impact on battery life. I hit about 50% of battery life with it on in about 5 hours but with it off and moderate use I can get 2 days use.
Just a thought and I froze lots of the SNS syncing apps with TB. I dont use those since i use another program for FB.
I actually like the ATT Smart Wifi app. Shuts down wifi when not in use. I think the free version of Juice Defender doesn't do that.
I have now owned my 727R for 6 weeks, coming from an iphone 4. I am finding the battery life inconsistent from charge to charge and anywhere from barely adequate to downright poor. Maximum I have ever gotten was 26 hours with minimal use and minimum has been 10 hours with minimal use.
I have installed and use Juice defender, and have looked at a variety of apps such as cpu spy, cpu hound, traffic monitor. I have turned off notification as much as possible and all other tricks under the sun.
My phone does not seem to go to deep sleep often and a lot of times it shows as awake even though the screen was off for a while.
The straw that broke the camle was when I cmpared notes with my clleague who has a Galaxy S (I know, no 4g, no LTE, smaller csreen). But he is getting 90% battery life with wifi and bluetooth on after 7 hours 15 minutes (minimal use). In the same time period I am down to 60% with bluetooth off!
I am not planning on rooting the phone and using custom ROMS or Kernels right now.
What gives? What do I look at to improve battery life?
Thanks
i notice with out a lot of changes i get horrible horrible battery life. but with a custom rom like quick wiz. i turn screen down. wifi off. under clock it and use a battery saver plus task killer i get two days moderet (use
Sent from my SAMSUNG-SGH-I727 using xda premium
I would suggest since Roger stock rom sucks the life out of the battery to root it and use faux123 kernel and Gideon's script to under clock it. Im using at&t stock rom rooted and faux123 kernel and I haven't had a bad battery day yet.. currently 12hrs moderate use 73% still.... not bad at all. Give it a try.. its not like it could any worse lol

It looks like this isn't available for Skyrocket.
1) Does it work like it should, and does it save battery, or is the battery savings negated by other junk running with it in the background? Reviews seem very mixed.
2) If you got it on a SR, how? Would pulling the APK from another device work?

I hated my skyrocket when I first got it because the battery sucked. Never could make it through a full day of average use. I did a search, found out how to root and install a custom rom and now I love it. I can go a full day and still have 20% left. All I can recommend is rooting and at least remove bloatware. I've never seen a single skyrocket user happy with their battery life on stock. Maybe sell or trade it for another iPhone.

[Q] Zapping and Extended Life Battery... should I root?

Hello All,
I've got a Droid X with the handy and convenient one-click root method Z4root. However, my wife's Droid Charge is an entirely different story. So far I haven't rooted it because I'm hoping to use that as a last resort (I don't want to brick her phone).
She was having some trouble with battery life, so she bought a Samsung extended life battery. Instead of her phone dying within 4 hours of a full charge it could make it pretty much all day. But this week all of a sudden, even with that, she's back down to 6 hours, if that.
Early on when she got the phone I downloaded Advanced Task Killer for her and gave her some basic tips (low brightness, no mobile data, etc.), but I'm at a loss. I'm not sure if it's the GB update or what. I'm almost ready to root her phone and roll it back to Froyo because I think that's part of the problem, but I'm at a loss. Do you guys have any suggestions? Or is rooting, battery calibrating, and cleaning out bloatware my only option? I'd appreciate any help. Thanks Droid experts!!!
Don't use advanced task killer first of all. It will probably reduce battery life. GB update has made the battery better in all situations.
Whether or not to root is really up to you however if you do decide to root it is actually quite easy to root EP4D(the latest OTA update). Here is an easy to follow write up that I did:
http://forum.xda-developers.com/showthread.php?t=1434738
Personally I rooted my phone and I have loved it. When I was using stock rom debloating did help some with my battery life. The biggest difference I found however when when I flashed eclipse and imnuts pbj EP4D kernel on to my phone. Eclipse is an awesome rom that is already debloated and has been tweaked to run super smooth. Imnuts pbj kernel has lots of great performance and power saving features(for example the ability to undervolt). Running stock I would get about 8 hours of moderate use from my standard battery(1600mah) and 4 hours of heavy use. Running Eclipse with imnuts kernel I get 18-20 hours moderate use and 8-10 hours heavy use.

calibrating the battery would probably help. id check to see whats running; gps, wifi, bt, etc. also it could be a rogue app that is sucking up all the juice. juice defender could help and if u have no use for location apps u can go into setting/location and turn off stand alone gps, google location, and vzw location. but def root the phone and put a custom kernel and rom on the phone, there will be a big difference.
I find that Facebook often runs rampant and needs to be told to stfu constantly. Also, a custom kernel with aggressive undervolting will help too.

4.0.4 heavy battery drain

Hi,
Has anyone else had problems with the battery draining with the new 4.0.4 ? My GF Nexus S was still on 2.3.6 so I got the factory version of 4.0.4 and installed it. I obviously wiped the data/cache/etc. Also I rooted it with the latest superuser.
I'm running the latest nighly of CM9 and everything is perfect, so I thought it was time to give her the sweetness of ICS.
So with all that useless information, has anyone found a fix for the battery drain in 4.0.4?
Thank you,
WarpedMonkeys
Since I installed 4.0.4 my battery lasts up to 20 hours, no problem at all.
I'd suggest manual full wipe with fresh 4.0.3 stock rom and then manual ota update to 4.0.4.
I'm also using matr1x kernel, it's just awesome
Hope it helps

Yeah, me too! Try another ROM. I am currently using CyberGR-MOD|NS.NGN ICS v10 HYBRID and getting superb battery life (and performance, mind you ).

Stock rom is ok, but updating with ota from 2.3.6 to 4.0.4 may lead to bad battery behaviour. Someone says that battery stats wipe could lead to better battery performances, but I think fresh install could do the trick

Check your battery usage, if Android OS is using more than 8-9% after some regular usage, then that's the cause.

A full battery cycle could do the trick. Don't let it die, anyway, because it can cause battery wear... Just take it to 10% and recharge it nighttime... You may also wipe battery data before, if you wish...

Heavy battery drain ??? i don't have any issues with it, infact i have not touched my phone for 1 day 6 hours and 25 minutes and my battery dropped from 95% to 82%. My phone was fully charged (didn't go higher then 95%). I am very impressed by the results.
I changed 2 settings:
1. Automatic screen brightness.
2. Turn screen off after 30 seconds.

Do you use 3G to connect to the internet? Never got more than 20 hours on 3G/HSDPA... without even using the phone!
Hello,
my Nexus S was updated automatically to version 4.0.4. I will tell you. My problem is with data. Now I can not open any WWW page in default viewer,Opera sometimes opens some pages but quite rare. I can not get any email in K9 Mail. Update of Google maps took several hours, unfinished, eaten all my battery! Sometimes I am without signal or with bad signal.
It is for sure problem with 4.0.4 because I have unlimited data. So, no FUP in this case.
I was satisfied with 2.3.6. How can I do downgrade without rooting etc. my phone ?

Best rom on battery saver

Does any one know what is the best rom to save more battery or the best kernel. Now i have gb 2.3.6 here is an screenshot
Sent from my SGH-T959V using Tapatalk
Look at the guide in the first link of my signature. The ROM's listed (icbinb included) coupled with AntonX's kernel and one of the tweaks, I think, will give you the best combo available to us.
Remember to keep wifi and sync off when not using. Use Gemini App Manager or similar app from market to stop apps from unnecessarily starting when you don't need them to. If you don't use wifi calling remove or freeze the app along with other apps you don't use. Read about undervolting your phone. I feel like that has helped me.
Thanks a lot...

I run the latest version of Valhalla black(not FB) and I can get a day's use no problem. Looking at my phone now, it has 8 battery left and is at 18hr 41m. This isnt right as I took it off the charger at 8am this morning and its 2:30am now. Hasnt been on charger since, so thats pretty good in my book. I leave Wifi on, but it only connects when I'm home. I did a full shift of work, 8-5 on 4g. Heavy texting, some web browsing and small time on other apps, downloaded some apps. Just all basic use of my smartphone. I never had to worry about the battery on this rom. Use the music app to play music through my car during commute. Yeah, this is what I would suggest to use as a rom. I have been on Valhalla for a few months now. Only thing that is weird is random reboots. Which only happen... maybe once a week. It doesnt affect anything, well, not anything to my knowledge or the basic use of my phone. So yeah, results may vary but give it a shot!
Thats pretty good.... I charge my phone two time a day... May be bad battery.... But i think that i need to change my rom first...

I'd say Hebrew Valhalla with atonx's latest kernel and undervolting has had the best battery life for me. I can easily get through the whole way with moderate to heavy use while still having 50% battery left when its time to go to bed. As long as you don't change the localizations, its completely in English so think of it as Valhalla final but updated. I love it!
