Hello i am new to android and smartphones period
And i am little confused
I went to school withal a 95 percent battery
And did not touch it for 7 and a half hours
And it went down 30 percent i made sure all the applications were closed
But some still seem to re open or some open with out me opening it
When i put it on airplane rode i only use 3 percent battery any suggestions appreciated
 
You certainly have something configured incorrectly or have things taking too much resources. The battery life on this phone is excellent.

What are your settings under screen and do you have apps syncing in the background on set to notify you frequently? What apps are running in the background?

Have you tried Juice Defender with the proper settings?

Did you properly calibrate the battery prior to extensive/normal use?

I have my customized screen settings but i don't touch the phone at all games and the web nite i make sure they are all closed
What is juice defender
 
First step would be to check the battery stats to see if there is an app or something else causing excessive drain.

Next (if any of the following are applicable) would be turning off live wallpaper, configuring any apps such as Facebook, Twitter, or weather that refresh regularly and increase those refresh times. For example, on Facebook, you can set it up so it never refreshes automatically, and only refreshes when you open the app. The less apps are refreshing, the less battery drain there should be.

If none of that helps, you can try Juice Defender (which is an app that turns data off while you aren't using it, and adjusts some other settings to try to help add battery life) and see if that helps.

You can always do a factory reset and add apps back one at a time and see how it affects the battery life (very tedious, but sometimes the only way to pinpoint an app that is causing trouble).

That being said, when I am not using the phone I tend to get a drain of somewhere between 2% and 5% per hour. One thing that can affect it is the reception you have at various locations (the poorer the reception, the harder the phone will have to work to find/keep a signal, and the more the battery will drain, and vice versa).

You can also try a different launcher - one like Zeam that is pretty streamlined and light on the battery - and see if that helps. As an anecdotal example, I recently switched from ADW EX to Zeam Launcher and so far it has increased the battery life at least a little bit.

At the end of the day, a lot of it is trial and error.
 
in 12 hours of non-use my phone will drop from 100% to 85%. i have syncing turned off, wifi off, apps closed and run the free juice defender app at default settings.

the battery life on my skyrocket (idle and while in use) is about the same as the iphone 3gs which i think is pretty good.

Yea that may be the problem i go to school on an perforce base and it has almost no reception

Little or no reception will kill ANY smartphone, and it can do it in as little as an hour.

The phone is constantly struggling to maintain a connection, bouncing from tower to tower.

If you are in class and have no need of the phone, it's prolly best to turn it off, or use airplane mode

turn off airplane mode/turn phone on when on breaks and when you leave...

;)
 
I was having battery problems too and thought the Skyrocket's battery was just shit. It would go from a full charge to 30% or less by the end of the day with little use. Just a few texts and a call or two. I was frustrated so I came onto these forums and others were complaining about the Skyrocket's battery as well. I finally figured out what was draining the battery, the Wi-fi.

Wi-fi DRAINS THE BATTERY EXTREMELY FAST!

Turning off Wi-fi improved the battery life significantly! Before I was charging my phone every day but since turning it off the phone can last about 2 days, maybe even more if you turn your brightness down (I have mine at max, can't stand dim screens) and use some battery app.
 
Wow! I noticed that my Skyrocket has horribly short battery life, and yes I have Wi-Fi enabled...

I've got Juice Defender, and set it to slightly modified Extreme setting. Will report here how it fares now.
 
Instead of turning WiFi off, go to settings>wireless and network>WiFi Setting. Hit the menu button and select advanced, select WiFi Sleep policy, and set it to turn off when the screen turns off. Mine is now on all the time and my battery lasts forever.

For whatever reason, every time I go back to find where that setting is, it always seems as though it's reset itself to "never," but my battery doesn't drain like it's set to never. another bug a suspect.

And... burying that option that deep is an annoying OS design.
 
Hmm... In combination with Juice Defender Ultimate, this setting killed my Wi-Fi completely. I had to turn it off and reboot the phone to get Wi-Fi back...

Yeah, I keep seeing references to this mythical procedure too. There's nothing about it in the manual.

Because it is known to decrease the life of lithium ion batteries


calibrating the battery is simply this

plug phone in and charge to 100%
unplug and let drop to 99%
plug phone in and charge to 100%
unplug phone and turn it off
plug phone in and charge to 100%
unplug phone and wait 5 minutes
plug phone in and charge to 100%
repeat until the time it takes to reach 100% is minimal


per those that have electrical engineer experience, this is bad for these batteries, as well is letting them drain completely and recharging them. The "sweet spot for charging is between 35-80%" supposedly.

now me being the rebel that I am...I charge the phone when it's dead, and have done the calibration and have yet to see an ill effect on this phone or others.

The top battery drainers:
-Wifi WHEN NOT CONNECTED TO A WIFI HOTSPOT the wording above is a little misleading, your battery is actually going to be twice as long while connected to wifi.. If you are not connected, the wifi radio searches for a spot to connect to every 30-90 seconds...the carriers did this. They want you connecting to wifi whenever possible.
-GPS when constantly web browsing with location sharing turned on, and ONLY in that situation
-Social media apps and syncing apps
-The screen on these phones..use auto brightness

that being said, I turn wifi off automatically
a. by schedule with timmeriffic
b. by gps coordinates with auto wifi enabler


I sync facebook and google

I actually uninstalled juice defender because it seemed to do more harm than good (connections not coming back on, battery drain actually increased)

I try not to discuss my battery life because it is biased, I am rooted running custom pretty much everything lol, and get 20+ hours with heavy usage


for more information on the battery tech just look up li-ion battery care

all of the above are in the links I posted in the other thread btw :p

I am working on a skyrocket specific battery thread but I am swamped right now
 
Interesting. Yeah, that procedure would be very bad for a L-ion battery, especially if repeated often. I just got a new battery from AT&T today. It won't fix the stuck indicator issue which is the reason they sent it to me but I figured if they're giving away free batteries, I might as well get mine.

It's a Samsung battery in a small plastic sleeve but it is enclosed in a much larger AT&T printed zip-lock bag. On the bag it says:

1. Fully charge your battery until the "Charge complete" indicator appears on your phone display.
2) Continue to use your phone as normal without charging until the battery indicator shows LOW.
3)At that time, please fully charge your batteryuntil you see the charging completed indicator.

So, yeah, LOW... is not DEAD.

I probably shouldn't be charging it every night when it only drops to 80% typically in the 16 hours I'm awake. I could easily go 3 days between charges with my typical use.
 
hmmm then i guess i'm doing something wrong or am an extremely heavy user? i do web browse a lot, and my phone usually lasts less than a day, and sometimes when i go to sleep the phone dies from 30%... i go close the programs and clear the rams before i sleep... but i notice a significant drop.. and i tried the juice defender, but i mentioned before that i need google voice to have access to internet at all times, since people call and text me on that number. does anyone know how to fix these issues? and know how to enable google voice on juice defender?

p.s. i have my wifi off, gps off, and have battery saver mode on (and i use much less battery on wifi on than off)
 
My trouble started mid nov when i took this phone... I charge phone 100% and without usage charging drop morethan 20% hr....by evening 4 pm my phone is dead... This is happening like that almost everyday.. I used iphone 3g, 3gs, 4 and i am really surprised that someone even comparing charging with 3gs... If that is true there is definately something wrong with my phone.
1. Tried closing all apps and just keeping factory settings...
2. Tried close wifi and 3g and check.
3. Use juice defender, not much improvement infact that app made my phone loose 4g forever till i reset to factory settings...
4. Att sent me a new battery but still problem is same with new battary..

i am almost loosing confidence on this phone...
Finally after all tries i reached this forum... If anyone know a solution please let me know...
As a final option
Is there anyway i can change this phone 2 months old (i dont even want samsung at all)
 
Open Google talk

Menu.settings.unchecked auto sign in

Turn off Facebook sync


Another's strange issue I have heard of....do you guys/gals have active alarms set during this time period of drain

Turn them off and let me know the results

Thanks ed for response.
My phone is reverted back to factory settings so facebook is not setup anf gtalk is not even there.
Today t turned off 4g and wifi still my phone lost 8 % in 45 min... This is with new battary sent by att...
About alarm there is one alarm in the morning, but nothing in day time. I turned that off and will update you.
Few days back i observed one more bug even after removing all alarms my phone raise an alarm at previously set time...
 
I've become pretty good at shutting down everything except the phone features, to preserve battery life. I figured out that if I have email set to MANUAL, I use more battery clicking on the icon over and over to see if an important message has arrived, than if it is set to automatically download.

I charged mine to 100% at 4pm yesterday. No usage over night and it alerted me it was 30% battery life remaining at 8pm this morning. No alarm, no syncing to anything automatically, no wifi, and the signal strength on LTE is excellent.

I have now fiddled around and went past my 30 day return window. Wow, how nice it was back in the day when I could work in the shop and listen to my favorite music without having the phone plugged in.......
 
Ok i will try and find an app that can help is tact the battery loss

When you go to menu.settings.about phone.battery use

Take a screen shot and upload

Now press the graph and screens that

I haven't figured out how to take a screen shot yet......

My Display shows 25%; Android System 16%; Dialer 14% and everything else is single digit numbers at 22h 4m 56s on battery. I guess the time means since the phone was turned off last because I charged it for about 2.5 hours this morning to make it through the day.

I have my screen brightness on the lowest setting possible and only turn it up when I'm outside and need to read something and the screen timeout to 30 seconds.

I must have a bad battery. What is the use of having a smart phone that has every feature turned off or the power runs out? If everyone has these issues, folks would be jumping off the Samsung ship in a hurry.

My screen shots/ battery life are with everything on fyi..

If you aren't getting that kind of battery life you are doing something wrong. Yes I am rooted, but the average user should be getting that life with no tweaking to the software.

Sorry, it's plain and simple truth.

I can't help you guys If all you want to do is complain.

I'm out of here
 
Not trying to make anyone mad.......I thought I was just telling the story and hoping someone could point me in the direction to cure my mistakes.

Sorry if I insulted you or your Skyrocket. :rolleyes:

You don't have to leave, I'm outta here for good.
