Im trying to recalibrate my batter because of terrible battery life. After letting it die and charging it while its on I had no issues getting it to 100%. I powered down the phone to charge it while it was off and it seems like its hanging at the last percent and wont go to 100. I have had it plugged in for a few hours now and its still showing the same charge but wont fill up the last little bit of the meter. Anyone have any ideas? Im really thinking about tossing the battery and getting a new one. It seems like i got a bad one. no matter what I do i can only get about 12 hours of light use. I work 10-12 hour days so I have to constantly worry about my phone dying everyday I work.
I had the same issues. Tried every battery trick I found on the forums, but nothing worked. I went to ATT, they sent me a new battery and it everything's good now
So try talking to ATT and getting a stock OEM battery before you buy one
I picked this up and it gives a lot of peace of mind: http://www.amazon.com/gp/product/B004206TQ8/ref=oss_product
Dngen. Are you getting greater battery life now that your using a different battery? I'm convinced the first batch of batteries and phones were bad.

At first I thought it was the phones that vary in battery life.
My first captivate had really good battery life. But it bricked after I tried to do the JH7 update. So I got the phone exchanged, but they used my original battery in the new captivate. For some reason my phone was draining really fast compared to my old captivate, and this was weird because both used the same battery.
This was really annoying me cause I loved this phone, but the poor battery life was ruining it for me. So I went to an AT&T store and told them how bad my battery life was. They shipped an OEM battery for free and I've found a new battery to significantly work better than the old one
Hmmm. I just got a replacement phone and everything works better...GPS ect... but the battery was the same as it is now.....10-12 hours. I've been thinking about getting another battery but I don't know if that will fix the problem. I guess I will try to anyway.

How long have you had your replacement phone? I know my battery life got better after a few days with my original captivate
I got my replacement phone about a week ago...I've been trying to drain and charge to make sure the system is getting a good read....I've had the battery since launch...the only time I got great battery life was when I used unhelpfuls undervolting and the first time I flashed jh7. I have only flashed one rom on my new phone. It just bothers me that it drains 5-6% an hour in idle. I don't have any Widgets and the only thing that is updating is email once an hour

I think I might have caught a break....on my fourth day of charging and draining and I'm at 16 hrs with. 27% left. I guess ill continue with the whole charge and drain thing for the next couple of days.

I somehow doubled my battery life. After draining and charging the last few days I managed to go from 12 hrs to 24 hrs of battery life while using it the same amount as before. I have had had my phone since launch and battery life sucked. I don't know it its because I got a refurbished phone that did it or what. I flashed my old phone almost every day for awhile. Even when I didn't flash I couldn't get it to last.

Have you guys seen this thread?

Good stuff, thanks
I've seen it and read most of the battery threads out there. I've come to the conclusion that: 1. There's a bad batch of phones out there that cause battery drain issues or 2. Since most of us ATT android users are new were unaware of the proper procedure to flash roms. I believe the second to be more true since most of the batterry drain issues happen due to flashing new roms according to most of the threads I've read. I would like to see the percentage of people out there who are still running there cappys stock with never Modding or flashing to see what type of battery life they are getting.

Before rooting, sideloading and flashing unhelpful kernel I was getting the same battery life, 10-15 hours depending on use. The only thing unhelpful seemed to help with was my idle usage, about 1%/hour. I still need to tinker with the kernel and try wiping my bat stats. My phone reports the battery is at 5% but when I shut it off and plug it in it's more like 30% lol
Sent from my SAMSUNG-SGH-I897 using XDA App
I had the same issue. Charge until full. Turn off and charge full... turn on and repeat. Erase battery stats via CW. The key is to let it die. Do not charge your battery until it dies....once it died I plugged it in and turned it on. If its at 1% then just let it charge completely. If its at 30% then you need to unplug and let it die again. Keep doing this until its at 1% when u plug it in. If you have to do the latter you have to start the process over again and erase stats and drain and fill the batterry. From here on out anytime you flash a rom make sure your phone is at 100%. Always let the phone die before charginging it the first time. I think the android system has to get a read of the batterry.
I think at some point along the way I charged my phone when it was at 30% after a flash so anytime after when my battery was dying I still really had 30% battery left but android was telling me my phone had no juice.. let me know if this works for you....

Hello I am new to this forum, I just got the Samsung galaxy s 4g this Wednesday and I was wondering if anyone else was having battery issues. Right now I have my phone set to minimum brightness, auto sync off, black bckground and juice defender on. So I don't understand why am I getting only about 3 hours of battery life when all I'm doing most of the time is surfing the web(this forum) and facebook. I even get better battery life from my dads vibrant which is completely stock, has auto sync on, no juice defender, and screen brightness set to 50%. From reading the stats of both phones, the vibrant 4g is supposed to have a slightly better battery. I also don't understand why if the screen is at the minimum it still takes up 94% of the battery whereas on my dads vibrant 50% screen brightness takes up 30%. Is there anything I can do? Will wiping the battery stats help? If so how do I do that from a stock unrooted vibrant?

Check your notifications settings. I know that Samsung's contacts integration with social networks takes a big toll on the battery, hence why I've disabled it. Also, disable T-Mobile's Contact Backup Sync, just use Google's contacts integration.
Thanks for helping, but yeah I have those disabled already.

No, I charged mine this morning at 630AM, and I have been playing with it all day. It is currently 610PM, and I am at 60% still. Seems pretty good to me.

Does the trick to fully discharge and recharge 3 times work with these batteries? According the the Li-on technology this is not supposed to be necessary but I've heard stories in the forums of folks getting great battery life on other phones after doing this. Many people also say their batteries work a lot better after a week of use (supposedly after "training" them as well.)
I believe the G2 is clocked down for this reason. You could try CPU-set app, clocking down to 500-800mhz when not gaming.
Anyone tried these tricks?

Will ill try to cycle charge the vibrant and use it for a week, and ill try out cpu set. if this doesn't improve I'm definitely returning this phone. I had soo much expectation for this because I have seen people getting up to 24 hours. I can't even get halfway through the day barely using the phone.

Im having the same issue with battery life.. for me its a deal breaker.. I use my phone pretty heavily for keeping up with email and a little web browsing as well as talking quite a bit.. My iPhone 3Gs lasted me all day of heavy use and with the SGS4G I have to charge the damn thing at least once a day with light usage and if I have to be on the phone a lot then its twice a day.. Not acceptable at all...
Thats with wifi and gps disabled..
On the 3Gs I had wifi, bluetooth and the gps running all the damn time...
Took my phone off charge at 6:30 this morning haven't put it on charge yet at 88% never had this much juice with the nexus one.

I'm not having any issues with battery life or heating. I use wifi teather most of the day and I'm getting to use it all day without issue. I did cycle my battery 4 times already just in case it matters. FYI
The batteries that our phone uses DOES NOT require u to cycle the battery. In fact, doing so will harm your battery. To avoid damage to your battery always charge ur phone when u r at <15% battery level. Trust me I thought the same until I did the research. I will post more info when I get on my PC later.

I just bought a Galaxy S 4G on wednesday. First android device coming from iphone 3G. I'm still trying to figure out the best way to preserve the battery life.
I took it off the charger at 6:30am and the battery was at about 2% at 8:30pm.
I haven't rooted the phone yet to remove some of the bloatware that comes pre-installed.
I've got email accounts synching, brightness set at about 10% w/ a static wallpaper. Played about an hour of angrybirds throughout the day and didn't really do any web browsing with a few phones calls. I mean 14 hours is decent but from what I've read there are plenty of people getting a full day of use and still have 50% battery left.
I guess once the battery fully charges I'll put inception on, turn off syncing and try a few other things.
So I guess I said all that to say this, my battery life isn't great but it's not downright horrible either. Any suggestions would be much appreciated.
And yes I'll continue browsing all the forums to see what else I can find.
Edit:
Played through half of Inception in airplane mode, brightness at minimum. I dropped from 93% to 80% in an hour and a half. Not too shabby.
Also created a shortcut to toggle between 4G modes and Edge. I know 4G is going to be a pretty big drain so I'll see how much that helps.
I'll keep tweaking it.
this is completely true and if you read the manual on page 13- h t t p:// downloadcenter . samsung . com/content/UM/201102/20110224044646930/T959_Galaxy_S_4G_English_User_Manual.pdf it says that
"• Do not wait until your battery is completely depleted before charging
your device. Repeating this process of a complete discharge and
recharge can over time reduce the storage capacity of any battery."
right now my phone is at 23% battery level with up time of 46:46:40 hrs/mins/secs. with skype calling (around 10 minutes), text messaging, browsing the net (for around 5 minutes about 6 times a day), and talking on the phone (around 15 minutes)
the settings i did:
1. took a picture with my finger blocking the camera to get pitch black picture and set that as my background and deleted all the shortcut icons (i short, i only have a blank screen with the only 4 icons down below)
2. changed the brightness settings to 2 clicks to the right from 0% brightness (or you can lower your brightness all the way down during the night, and 2 clicks away during the day, this will save you more)
3. disabled haptic feedbacks and audible touchtones, selections, and screen lock sounds
4. disabled animations
5. disabled background data and syncing when not in use
6. disabled packet data (3g), wifi, and gps when not in use
the last two are the biggest settings that made my battery last longer.
7. i only charge my phone when it gets to 20% and the manual recommends not to use the phone while charging
i hope this helps.
and yes it is recommended to charge your battery to 100% before you turn on your phone for the first time and this is also stated on the manual.
one more thing, don't forget to set your browser's brightness setting as well

I've been using it for ten minutes on the charger and for some reason the screen brigntness was low. So I went to the settings and it says "to avoid overheating maximum brightness has been reduced".. and my temperature is 47 degrees now. Anyone elses phone getting hot?

This used to happen with my Samsung Vibrant 4g... i believe you could burn the phone if it continues, it might be a factory issue.
Same here, charging on the wall charger with screen off, it hit 47c and won't go to max brightness.
I've also jist noticed after 50% the charging time decreases significantly. I went from 50% to 90% in 45 min

Mine got hot and I lost all service. It was up to about 93% charge and it just lost all cellular service. I had it rooted but didnt carrier unlock it. Got a replacement phone this morning and Im leaving it alone to see how it does while charging. With the long charge times this could be an issue. Not everyone can let a device set and not mess with it for 3-4 hours, lol I know I cant.

Technically I don't think you are supposed to be using your phone while on the charger... This happens to all phones just some heat up faster than others.... My old ATT Startac did that, SE W900, Captivate, and this one.
It really kills the life of the battery too as well. Nature of the beast....

So I just switched from a rooted Evo to a Charge. I rooted it on day one and have had what I consider to be poor battery life. With everything off except mobile data, I'm losing about 5% per hour just idling. My Evo would lose 1% an hour or less when running AOSP roms an little more with sense roms.
I took my phone off the charger around 9 this morning. I've sent 50 texts, maybe a few more. My battery is as 52% right now. Maybe I expected too much, but I didn't get a TB because of the crappy battery life.
Right now I'm running Gummycharged 1.8.1 with the standard kernel that it came with. I don't have 4g here so I have that auto search turned off as well.
Is normal or should I unroot and bring the phone in?

From my day to day use, this sounds about right. You have 4G kn right? Not 3G? If on 4G this sounds totally accurate from my experience.

I get roughly 19 hours on a charge with my thunderbolt..so not sure what you ment there...anyway it looks like you are getting 8-10 hours.. that's normal
I get anywhere from 8-10 hours of heavy use, when I say heavy I mean it, music and browsing the web at the same time, calls and browsing the web at the same time, txting, skype, email.. but keep in mind while I do have the stock battery I kill EVERY task and clear RAM whenever I set my phone down, the biggest killer of battery life is just tasks running in the background, remember this phone has a built in task killer, even when rooted & ROM'd.
Another tip would be to keep a spare battery in your wallet, when I stay over at a friends and don't have my charger or I just need a quick full charge I just pull out my wallet and switch the batteries, it's only like $10-$20 for a spare battery depending on where you get it.
If you want longer battery life, you left on the only one that is key to saving the battery !! If you are just in standby or just using the telephone and textings, turn off mobile data, that is the power sucker. Turn it on as needed. Even if you are in a 3G area, the LTE chip stays powered up and this is a big drain.
My phone will last the weekend using this method.
What actually drains the battery is having your screen on. Look at your battery stats in your settings. That will show you what is killing your battery the most and then you can adjust what is needed

Hey guys,
Normally I would want to charge overnight, because the time other than my sleep is when my phone is near a charger or when it's not in use hahahaha . But, I don't want to charge it a lot more than it should be charged, in fear of destroying the battery (I'm planning on holding onto this phone for quite a while). So I have two questions coming from this...
1. What ways do you guys charge your phone that suits you?
2. Any ideas what could be a good way to charge my phone at night without overcharging it? I've seen some adaptors that have "30min, 60min, 4hr different charge timers" but I'm not sure if those are the way to go.
Any help is appreciated,
Thanks
