[Q] Disappointed with the battery life... :( - Samsung Infuse 4G

Hi folks - this is the first thread I have started, hence requesting the non-noobs to go easy on me... (this forum is a scary-kind-of-cool)
I mustered up the courage to install Infused 1.5.0 on my stock... the instructions were superb and everything went great... really enjoying the improved speed and looks. But my battery life has degraded. It has been more than a week since I flashed my phone - and it is only getting worse. Now I have read a lot about how Infused is getting great battery life for some folks... and i have gone through those threads, trying to figure out what I am doing wrong. This is my typical usage profile
1) I put the phone on charging before I go to sleep... when I wake up (around 7 AM) it is fully charged.
2) I quickly check overnight messages, finish the daily ablutions, and 30 min later when I check the phone it is already at 95%.
3) By 10 AM, I have made a few long phone calls (no bluetooth) (totalling 60-90 minutes) - and the battery is down to 75%
4) At work I use a bluetooth A2DP headset - maybe 30-40 min of calls and by 12 I am at 50%.
5) More calls in the afternoon, intermitted mail checking and sometimes 30-40 minutes of music streaming on my bluetooth headset - and by 6 PM my phone is down to critical level 12-15%.
This is in now way the same experience that others are having with the Infused ROM and with the Infuse phone in general.
Other points:
6) I run Juice Defender... (don't know if it helps)
7) My screen brightness is just a few notches over 0%
8) My data is always on - except when I am using Wifi of course
9) I turn bluetooth off when I am not using it
So that's the story guys... and I would eternally grateful if the awesome folks out here can help me figure out what I am doing wrong... or there is some logic behind the sad battery life of what is otherwise the best phone that I have ever owned.

It depends how long Infused has been running on your system. After about 3 days I noticed my phone was adjusting to the ROM and the battery life improved significantly. Aside from that, try this trick. Drain your battery next to nothing and then charge all the way. Do this a couple of times. Not quite sure about the logistics but it seems to work. Another thing that has improved my battery life is to make sure I don't have background apps running. You can check this by going into apps > manage apps > and then running. Sometimes Media Hub will begin a background process and that eats up a whopping 8 MBs alone. Force close these pointless background apps and you should see an improvement there as well.

have you conditioned the battery and reset battery stats?

Thanks popesmasseuse (you really aren't are you?)... the ROM has been running now for a week... gets worse rather than better. I do typically wait for my battery to drain completely before I charge it... but when I do have to do it at 7 PM - then I can never charge it fully, before I have to start using it again. I wonder if the fact that my phone goes through "micro charges" is a reason for my declining battery life...
Will check the running apps... and see if closing them improves things... thanks!

Fact: Installing a ROM greatly improves battery life... Try it....
Turn of GPS and Bluetooth when not in use.
Same here I uninstalled media hub... period... just useless...

Phone calls are a pretty heavy battery drain. Sounds like you're in call for hours each day. Most people don't talk on the phone more than a few minutes a day. Poor signal will also significantly reduce your battery life... how many bars you usually have at work?

My battery life got better the longer I had the infused ROM. But personally I only talk on the phone maybe a total of an hour each day, but I am constantly using internet and youtube, and if I have spare time I'm using my Kindle app to read some books. I keep my GPS, sync, and wifi on all day long and my brightness all the way up (I just can't stand a dim screen lol) and by the time I got home today my battery was at 40%, which I am perfectly fine with.

Ah...the man himself.
Yes I talk a lot on the phone - nature of the job. 3 hours minimum in a day. Signal at home is terrible - 15% strength... that could be the reason why the battery runs dry after the morning routine. Any way to offset that?
At work signal is great. But in office I also tend to use my desk phone more...

Read this post in another battery thread I am doing this right now to see how it performs afterwards.

Read the thread in my sig.
Never use task killers.
For me, battery life on phones gets good after about 2 weeks or so.
With light to medium use I can easily go for 2+ days.

Consider not streaming music through Bluetooth. Also don't auto sync stuff every 15 mins. If you can use Gmail they use Push notification. I'm on my phone all day literally and I make it home with some battery left. BTW connect to a Wi-Fi when ever possible, 3g data streaming will kill your battery quick.

has anyone tried this method?

It's a Lithium-Ion battery which means it does NOT respond to "conditioning".
"Reconditioning a battery involves completely discharging the energy from a battery then recharging the
battery. Li-Ion batteries do not require reconditioning to maintain good battery performance since Li-Ion
does not have a memory effect. It is necessary to complete drain and then recharge a Li-Ion battery in
order to determine its current capacity level, but that is not the same thing as reconditioning the battery. Li-
Ion batteries do not have a condition that needs to be reconditioned." lxe.com

Keiht's tutorial is effectively a technique called "bump charging" for putting that last extra percent or two of charge into a battery. However - with Li-Ion batteries, charging like this will SEVERELY reduce their charge cycle lifetime.
The only thing that "calibration" should affect is how your device reports battery charge level, NOT actual power usage. You should get the same total battery life whether your device is "calibrated" or not, with the exception possibly of the device shutting off prematurely because it thinks the battery is lower than it really is.

I would have to agree with you. I followed his directions as i was having horrible battery issues after going to 1.5.0 and it seems to have helped the reporting as far as I can tell. I think the big problem and it is only a guess is how the phone is reporting the battery condition not actual battery left. In any event I am running JD and the longer I run with 1.5.0 the battery seems to be lasting a lot longer but I have ti disable most everything which hobbles the phones best features to get that battery life still searching for the perfect solution.

[Q] How can we improve the battery life?

My Droid 2 global's battery life is not good,nearly 1 day for each full charge(i used room fission 2.4.3)Is there any way to improve the battery life
If you're getting a whole day out of one charge that's outstanding battery life.
Sent from my Droid 2 Global running Fission Rom
Too sad to hear that exacly i used about 20 hours.How about you?i heard that if use CDMA the battery life will better?
I've heard something of the like, but nothing conclusively. I've heard that underclocking the cpu can help (if you want to root your phone). So can using a rom like Fission, which doesn't have the stock Blur that, although somewhat nice, is a big drain on batteries. This would naturally be a pretty big change though. You can also get the extended battery for <$50 which I heard helps a bunch.

Yep,underclocking the cpu and use room Fission make the battery maintain more longer(i'm using gsm not cdma).In my country (VietNam) someone sells Droid's battery for only 10$,i'm thinking to get one
Just got my D2G, I put it on CDMA only and the battery still sucks. It went from 80% to 40% overnight and it was set for night time battery save mode.

Wow that's strange, I left my phone overnight not charging because it hit 100% before I went to bed, and 10 hrs later it was still at 90%, sitting idle my phone uses nearly no power. However I never used the battery save mode and I only just recently put it in only CDMA mode just to see if that makes life any better.
I've found that the biggest drain on the battery is having mobile data switched on in an area where the phone can't keep a clear lock on 3G and is constantly switching between 1x and 3G.
After switching to Fission, underclocking, keeping gps and wifi off unless I'm using them, turning the brightness down to 10% except when outside in the sun, and managing apps that sync background data, I can use the phone pretty heavily and get a full day (15-18 hours) out of my battery. Considering I put it in the media dock for use as my alarm clock every night, that amount of battery life is perfectly fine.
BTW, I use SetCPU for underclocking. I set the max speed to 1GHz with On Demand scaling. I also have profiles to scale down the speed to 600MHz when the battery gets low or when the screen is off (which helps with the background data stuff). At 600MHz it's still faster than my original Droid, thanks to the doubling of memory in the D2G.
So far Today after 5 hours of moderate use I went from 100 At 50 on the battery. Is this normal?
Update:
Phone on for 7 hours and the battery is down to 30%, something must be wrong, right?

zse45tgb,
Does SetCPU only require root and SU?? BTW I used SetCPU on my Eris and it was a lifesaver.
Haven't gone the Fission route just yet but loved ROMs on my Eris, such a battery saver. Really hope the dev's can make it happen.
Don't mean to sound like a twit here, but I used to have a huge problem with the battery life... when I was dicking around with it for hours at a time. Try only using it when you need to. Don't sit on facebook/maps/using it for pointless things for extended periods of time. I have found that just using it moderately has had the most dramatic impact on battery life. I can maintain complete functionality of my phone when I need it, and still have at least 50% battery by midnight. If you are using it that heavily, then maybe you should carry a charger around with you? Hope this helps.
Idk how you guys get such terrible batt life. i have mine OVERclocked to 1.35 ghz. i also have profiles to lower that as the batt goes down. I have everything that updates set to update every 30 mins, which is quite frequent. i dont mess with screen brightness, i let it auto adjust. I play games on occasion (SNESoid), facebook frequently, alot of texting and my battery lasts 18-20 hours every day, consistently. When you first got the phone you let it charge for 8 hours right away right? if not...theres your problem, and your battery will probably self destruct in a few months...give or take a few months lol.
Use The Following Settings to Help Maxmize Your Battery Life
I've been using the following settings on the Fission 2.4.3 Rom and I've noticed my battery life has increased at least 6-8 hours longer. I was considering returning my D2G before, but now it is definitely manageable.
Installing the SIM Card HotFix using the Fission Rom Manager
Adjusting my mobile networks to "CDMA / EvDo auto" in "Settings" -> "Wireless Networks" -> "Mobile Networks" -> "Network Mode"
Underclocking my CPU to 1Ghz using SetCpu
If you really want to save some more power combine these settings with Juice Defender. I've noticed a bit of lag here and there while using it, but that's the trade off for longer battery life.
I can confirm zse45tgb post about losing a lot of battery in an areas with poor 3g reception. When I'm at work my battery will drop much faster then when I'm at home where my 3g reception is great.
Props to AngDroid and the rest of Team Defuse.
Hope this helps someone else out there begin to enjoy their D2G.

these are li polymer batterys...not nicad. lol. so they dont need "warming" up the first time... the first charge is the same as the rest. it should be charged in around 90mins tops. a li-pol battery isnt able to accept a trickle charge (would damage it) so leaving it on past 100% is uneccessary and potentially damaging. i wouldnt recommend ever leaving your battery on for 8hrs. as soon as its charged unplug it. if you leave it connected then the charger will switch off, you will then be using the battery, the battery will eventually drop to 90% and then the charger will turn back on. youll be continuously topping the battery from 90 up to 100 and back again. a waste of electricity and im sure it wont do the battery or charger any good.
theres also no need to fully discharge the battery.
a quote from http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
"Preparing new lithium-ion for use
Unlike nickel and lead-based batteries, a new lithium-ion pack does not need cycling through charging and discharging. Priming will make little difference because the maximum capacity of lithium-ion is available right from the beginning. Neither does a full discharge improve the capacity of a faded pack. However, a full discharge/charge will reset the digital circuit of a 'smart' battery to improve the state-of-charge estimation"

I purchased the BP7X extended battery from a local Verizon store for $37 with corporate discount. It makes a HUGE difference. With corporate e-mail, two POP accounts at 30-minute intervals, and about 2 hours of music playing, I had 40% left after 12 hours yesterday. I know some people want to see more than that left, but coming from a number of -gasp- Windows Mobile devices, this is pretty much what I'm used to.
T BP7X is 1820/1860mAh, vs. the stock BP6X at 1390/1420mAh. I've seen other batteries listed with as much as 3500mAh. I would think such a battery would get one throught the day with very heavy usage, but I don't want to think how large that battery door would have to be!
The first post at this link shows a comparion of a D2 with the normal battery door and the Moto/VZW extended door. As somebody posted somewhere, the extended door actually makes the device "feel" better in the hand.

Easy steps for battery life preservation

This is not a guarantee of battery life extension or performance. These are merely steps (in most cases) to possibly help prolong and restore battery longevity.
First lets understand something about battery charging. The most common mistake is to overcharge a battery. While one is inclined to charge when they see the low battery message, overcharging is detrimental to the battery. This is not good for the life expectancy of your cell phone battery, especially if you are expecting longer life from your battery. Over charging heats the battery, and drains its life expectancy.
Second, it would appear that after flashing (ROM’s, Kernel’s etc.) multiple times, your battery might not hold a charge all that well. Trying these steps may help improve battery life.
> Turn the phone on. Plug in the charger (not the USB to computer) and charge completely> Disconnect the charger and turn off the phone> Once completely shut down, plug the charger back into the phone. Let the phone completely charge, while phone is off. In some cases the phone may give a tone when charged. You can check its status by touching the volume up or down> Once again unplug the phone from the charger> These next steps are curcial. 1.Turn the phone on (give it time to boot completely) 2. Power it off again. 3. Connect to the charger once again. 4. Let charge to full one more time. Unplug the phone!
In most cases, this procedure need only be done once. Remember turn off bluetooth, intranet and other applications when not in use. These accessories pu a tremendous drain on a cell phones battery life. This is why they should be turned off, when not in use.

i feel like i do this every time i recharge my battery because every time i charge to 100% then turn it off and plug it in, it takes another 5 min to charge to 100 while its off. Literally, every time i bump charge it.

Mhmm, an explanation of the bump charge. Been written here before, but eh. Maybe someone lost theirs. I lost my txt file with the instructions a while back lol.
The way I see it these instructions only help to provide a more accurate battery count. Whether the battery is displaying correctly or not, juice in the battery is juice in the battery. Nothing more nothing less. This whole battery issue is ridiculous.
I think it'd be a good idea to remove the battery icon from the notification bar all together.

No. Your phone has software in it to detect how much battery life is left for a variety of reasons; it turns more battery-intense functionality off at 5%, the camera for instance, and keeps enough battery power so that it can run its shutdown procedure, instead of just dying and losing whatever's in memory at the time.
You also don't want your phone thinking that 19% battery is 1% and turning off or telling you to charge it, as charging a battery that isn't fully discharged is a great way to lose long-term battery life. Additionally, how much would it suck if your phone software thought that 75% was 100% and stopped charging? You could then be leaving for the day with 3/4 of your battery, thinking it was full.
There are plenty of reasons to want this to be as accurate as possible. Unless you just don't give a crap if your phone is usable or not

I was having all kinds of issues with my battery draining too fast. I unplugged at 7:30AM and by 10:30AM it would be at 60%. I tried the bump charge and all that, but then I realized "It's the apps, stupid!" I started running a task killer after I unplugged it, and now I'm making it to noontime and I'm only down to 80%.

If you are running a custom rom it is also good to delete the battery charge stats when booting back up after step 4. If you have CWM just boot into recovery, go to advanced, then clear battery stats.
There is a way to clear it if you don't have CWM, but I don't remember what it is and I think most people have CWM anyways.
I check my apps frequently. One day my weather widget was going nuts and was using GPS non stop. I pulled my phone out at lunch and the battery was in the yellow. Granted I haven't seen that happen again it has made me reconsider even using apps/ widgets with GPS
widgets kill battery. I had several pages of widgets and I had to wipe by phone, remarkable how much "better" the battery was after that. Weather widgets look great but it costs to run them.

I've a feeling it has less to do with the actual widget and more to do with their constant updating when there is a poor or nonexistant connection.

I would love some advice as a noob here. I've only had my Cappy for a little over 2 weeks. I've done the battery calibrate trick, but still don't see very good battery life. I unplugged from the charger at 100% at 10pm last night and left the phone on all night. Wifi and GPS were turned off. Beautiful Widgets is set to update weather every hour. The phone received 7 sms messages during the night. When the alarm went off at 6:30am I was at 70%. It's 10am now, so it's been off the charger for 12 hours. Here is what I show:
Voice Calls 34%
Cell Standby 23%
Phone Idle 16%
Display 15%
Android System 4%
Beautiful Widgets 3%
Android OS 3%
Android Core Apps 2%
antivirus 2%
Battery currently shows 51% left

Would anyone suggest Advanced Task Killer or Juice Defender?
There are some good tips for prolonging and caring for your Battery here: (Can't post links, google search: site:arstechnica.com battery life ask ars)
However, cell phone batteries rarely run over $30 (I have seen capivate batteries as low as $13), if you just always fully charge it you will still see a good 8-12 months out of it, and then just buy a new one. $30 a year is worth it to me to just let the thing fully charge so that I can use it for longer.

If you fully charge and run the battery, done several times, the battery will eventually run better. Surprisingly, there is a "break in" period for the battery.
I appreciate the advice on the task killers and such. I don't use one, and after reading that stuff, I won't. I pulled my phone off the charger yesterday at about 1pm. By the time I played some games, did some web browsing, made some calls and did some texting, it was still at 70% when I went to bed at around 10pm. This morning at 7am, I was shocked to find that it was still at 67%! I don't have a clue what was different. It typically hogs up 25-30% overnight, but this time it only did 3%. I wish I knew what was different. This is so weird!

[Q] How Many Times Did You Calibrate Your Battery Before You Gained Full Potential

I am now on my 2nd full charge. Drained completely and full charge while off. I have the battery calibration app and i use it. Im about to take my phone off the charger and put it to work.
How many times did you calibrate your battery before you got the full potential of it. I see some people are getting as much as 30+ hrs on their device while im getting 7-9 on moderate use.
I've never done that. Always read that draining lithium-ion batteries hurts the battery if done repeatedly. Instead I just charge to full then delete battery stats in clockworkrecovery. Battery has been great ever since that and a factory reset.

What does deleting the battery stats via ClockWork do? Do you delete them on each charge?
I was getting great battery life and then I used the calibration software and I'm getting good, but slightly less great battery life. Does uninstalling/freezing that app do anything or once it's calibrated, it's done?
The phone has a dual-core processor, and the best GPU you can get in a phone these days, so you can't expect it to get super battery life unless you never use the phone much. I did the calibration once, and have been able to go all day under moderate to heavy use. All day being 8am-7pm and still having ~20% charge.
Sadly my first g2x that I received wasn't able to go through more than 4 hours of standard use even after fully charged the 2nd time. I sent it in last Friday for exchange and now I'm waiting for the 2nd g2x to be send to me. Well see how it goes by then.
@himmelhauk - I noticed in your signature that you have the Paul O'Brien fix... I saw in that thread that that noticeably increased speed/smoothness, but I haven't heard anybody talk about its influence on their battery. Have you noticed a difference in your battery life after making that tweak?
Me
I only calibrated once, and that plus some other simple tweaks i saw great results. I usually get about 20+ hours of medium use(A few calls, non-stop texting, occasional game or youtube video, and checking email every couple of hours). If you want to see what I did you can click the link in my sig.

it gets rid of the battery information stored within the os so that the phone reads the battery charge correctly. this was common practice for vibrant owners after flashing a new ROM. I've seen people saying that this phone has horrid battery drivers so I dunno how that will effect the battery stats but after a factory reset and deleting the stats my battery is double what I was getting on my vibrant.
I only do this after flashing a new ROM or in this case upon getting and setting the phone up. I would do it again if I swapped the battery for a different one also. just charge to 100%, reboot into clockwork, advanced menu, wipe battery stats, done. it DOES NOT increase battery life. it only allows the phone to read the battery more accurately which would keep the phone from thinking its dying when it still has considerable charge left. that's why you hear about people seeing their battery life read 1% yet the phone last for hours.
I only calibrated once because I realized the values were off a bit.
Tried every battery trick in the book. If you actually want to use the phone, nothing will help. Android is a battery eating nightmare. Hopefully one day the platform will mature so adults can use it as a business phone. I think I am returning mine or giving it to my kid.
I did a single calibration and am now seeing 20+ hours with decent usage. Fully charge the battery, use battery calibration app to erase settings, let it drain till it shuts itself off, try pressing the power button to make sure there's no remaining charge, then fully charge to 100% with the phone still off (you can tap the power button while its plugged in and off to briefly bring up a battery indicator on the screen with out actually powering up). Its true that lithium ion batteries last longer if they don't go through fully discharge cycles, but thats referring to repeated occurances, not a rare or occasional situation. And when calibrating, draining from 100 to 0 is the best method of getting a good calibration. Additionally, while its healthy to do the mid charges most of the time, about once a month or so you should do a full drain. This helps keep the calibration accurate (remember that android will continue to modify the file, albeit at a greatly reduced level after the initial discharge of a new calibration, hence why that occasional full discharge is valuable). A full discharge once a month won't significantly reduce your battery's life expectancy.

Draining a li-ion battery past the safe shut off is an easy way to damage or completely kill the battery. Your phone is set to shutdown before complete discharge for this reason. The full discharge then charge method was for NiCd batteries. This has no use for lithium-ion batteries.

True, but the method of attempting to power back up won't actually drain it past the safe point. The point is bad calibrations (either from the factory or by an incomplete calibration) can cause the OS to shut the phone down prematurely during your new calibration run (before the actual safe cut off), resulting in the calibration being off scale. When you attempt to power the phone back on, if it is at the true safety cut off, it won't reactivate, where as if the calibration from before was skewed, it will allow it to boot back up and finish draining down to the safety cut off. This is in line with the reports of people having incorrect readings on battery %, where they have a low number, reset the phone, and suddenly seem to jump up 10 or 20%.

I honestly don't know if it made any difference on battery life, as I did the battery calibration before I installed the fix. At any rate, I get much better battery life after the calibration for certain.

I dunno about this phone but I know the galaxy s can still be powered on after the safe shut off and drained completely. People were doing exactly that and messing their batteries up. I would hate for people to misunderstand your post and end up making the same mistake. So the LG doesnt let you power on after the safe shutdown unless its connected to a charger? If so thats pretty good. In any case its a lot easy to just use clockwork, terminal emulator, or any other app to delete battery stats once your charged to 100%. No need to drain first

I hadn't heard about the Galaxy S phones having that issue. Like I said, I came from the Eris and this method was the way to go with that phone, so perhaps its a manufacturer dependent function. In any case, I agree that the cwm method is better, but I meant my post to be accessable by those who may not have taken that particular plunge yet, since it only requires root. Thanks for the info though; its good to know in advanced that the safety shut off being unavoidable isn't a guarentee on all phones (though frankly it should be).
EDIT: Not sure if I'm reading it wrong, but it sounds like you thought I meant to drain the battery before calibrating, which isn't true; all you need to do precalibration is have the charge at 100%. The only time I was suggesting to drain it is during the actual calibration run, so that Android has a full scale of your battery's range. If thats not what you meant, than ignore this edit. Just wanted to make sure I was explaining myself correctly.
Also, if you open your battery cover and look at the battery, it's not suppose to go above 40 degrees celsius, or 104 degrees fahrenheit. I found that the temperature often goes past this, especially when watching movies for extended periods of time, or playing games, which leads to a significant decrease in battery life because heat and li-ion batteries are not a good combination.

You can use SetCPU to make a profile according to battery temperature and underclock it when it gets to 40 degrees or something. I have profiles for when the screen is off and for temperature.

[Q] What are people's battery usage?

Well now we are all S-OFF and running custom rom's/kernels, was just wondering what drain people are seeing on battery under normal usage?
I'm getting 228mAh overclocked to 1.728Ghz with on demand with Leedroid 1.1 (kernel 1.2).
About 4 times as much as my old HD2 used to drain!
Kind of mental battery usage really. And not too impressed, it doesn't seem to be any different with or without background data usage.
Not sure I can be happy with this device the way it stands!
Getting about a days battery life and that's coaxing it through the day. God forbid I actually use it!! Done all the calibration and followed all the guides, still terrible battery life. Battery technology is shocking. Think I'd need a 10,000mAH battery to have any reasonable sort of battery life.
So what's other people's opinion??
its all about the setup man. takes time to find the settings right for what u use the phone for, and every phone is different. moderate use i can get 10 hours on android revolution 1.1.5. give it a few solid charges (all the way dead until you cant even get the phones screen to power on and then charge until the green light is on for over an hour) and then wipe battery stats when its at 100%.
If your that unhappy with it and nothings working call up your carrier they'll replace it for you, I did that with my G1
I feel the same way. I love this phone, but what's it good for when you can't use it. I find the battery levels to be a bit unusual. It could stay in 100% for a good two hours, and then it would drop to 90% in 10 minutes. And it just goes downhill from that on. I did battery calibration and cycling , but still the same result. I find myself avoid using the phone. I just ordered higher capacity battery. Hopefully, I have better luck with that one.

Moderate use (aka no gaming just emails, xda forum app 15mins, music 30mins, video 15mins and occassional internet), I've been able to last the work day til I get home. I usually still have range from 25% to 50% battery when I get home.
When I do any gaming app, it won't last me the day.
I end up having to charge the battery every night for the next day's use.
I carry the usb charger for wkend usage. I can almost always find somewhere to plug the usb in for charge (car, laptop, etc).
I love this phone and it's QHD screen. The display eats up a lot of battery though. I've calibrated my display lighting to 33% brightness (it's still looks great) as default to conserve on battery but will boost it to 100% when I'm plugged in.

Extended Battery

Anyone know where to get an extended battery? Thanks.
I can't even find a place to buy a regular battery for the phone. I'm not sure if I would need one, but it would be nice to have. I'm in the habit of charging it the last hour I am at work so no matter what, I'll never run out of battery even if I go somewhere straight from work, but a spare battery is always a good thing to have.
I have a wild guess as to why not.
I noticed this phone battery has the "near field communication" labeling on the BATTERY. The other phone that I'm aware of having NFC, (the galaxy s2) does NOT have this wording on the battery.
Why did I notice this? I randomly read that there is an SD card manufacturer that is putting NFC chip's into their microSD cards, and even some ipod cases are getting NFC chips built into them as well.
I don't know too much about NFC, but with the labeling being on our battery, and not the S2, I kinda think our NFC chip is actually in the battery, and not the phone itself. If an NFC chip can be put into an SD card or case on a phone that never had NFC to begin with, I don't see why it couldn't be put into a battery, especially since one of the terminals might not even be for power, but just for an NFC connection.
That's my theory, I could be wrong!
you're probably right. This is how it is with the Galaxy Nexus, also built by Samsung. I hadn't noticed the label, but I also wasn't looking for it.
I'd be curious to find out what an "extended battery" for this phone would look like. I'd be all for it so long as it kept NFC and didn't bulge out of the back
I'd be interested to find one. Being on a stock rom and standard battery, my battery drops about 5% in five mins just checking Facebook. GPS drains it another percent per min it is in use. Half way thru the day my battery is dead. It really sucks having to carry around a charger. I'm also using juice defender and other tweaks I know to save battery
I'd bet you a waffle cone your screen brightness is set too high.
Forget most of those "battery defender" apps, especially if they are those stupid task killing applications.....a program being in active memory is not necessarily actually doing anything, which means it is not using your battery, and if it gets killed, if the OS needs it open for any reason, it having to be re-opened will just use cpu cycles anyway
I'd agree with most people that using the automatic brightness option is very annoying, it's really sensitive and it also tends to make the screen not be bright enough. Having said that, using any of the many available brightness widgets can be a very good thing.
The stock one is not so bad, personally I've been enjoying powerful control, http://goo.gl/2vZXl but I've had great battery life and easy readability if I use the brightness setting where it looks like a half moon.
If you're outdoors in the bright sun, you'll need the screen to be as bright as possible if you want to read it, but otherwise it's fine. The screen brightness is always the single biggest battery usage factor.
Personally I've always disabled the haptic feedback as I think it's annoying and I'm sure that using vibrating alerts is also a huge battery drain.

My screen brightness is at zero without automatic brightness on, and im not using haptic feedback. The phone battery is fine if its just sitting over night, but as soon as I turn on GPS to use maps for 5 mins or to check facebook the battery just drops a % every min. So i guess the phone is fine if Im not using it, but then whats the point?
You're exaggerating.
I've never had a phone battery drop 1% per minute.
Look man, I just spent 5 minutes playing music at max volume, while getting directions to 8 different places in google maps, sent two emails, downloaded a new app from the market, and received one text message.
Battery level after all this? Still at 100%. Does that mean I can do this an unlimited number of times? No, it does not.
Frankly, I don't believe you. I've used this phone, and my previous phone for playing movies at full screen brightness with the audio being played through bluetooth to my stereo headsets. Does it effect the battery status? You bet it does.
Two weeks ago when I last played a snes game on my phone I did so at full screen brightness over bluetooth to a ps3 controller. When I wasn't playing the game I was sending or receiving text messages and had vibrate on. I played super metroid from the very beginning to almost through the end of the game. When I play snes games on my phone I tend to use quick save and quick load and frame skipping very commonly, effectively letting me do things "perfectly" but this is a lot of saving and loading and running the game even faster than how it normally is. I started at 2, and the next thing I knew it was 6:00 and I was supposed to meet a friend for dinner at 6:30.
But for crying out loud you are saying you can drain your battery from 100% to zero in less than 2 hours.
I'm calling shenanigans. I don't think you could even do that intentionally, unless you sat there and forced the phone to vibrate the entire time.
Phone batteries don't last for days like they used to. Batteries have not changed too much in the last few years, but the things phones do, and the screens they do them on certainly has. Stop expecting your phone to last over the entire weekend even when you actually use it.

Something to keep in mind:
When this phone hits 100%, it STOPS CHARGING. Even plugged in, it will no longer be drawing power into your battery, yet it'll still be running on battery.
If you plug it in when you go to sleep, it finishes charging within 2 hours, then it goes 6 hours idling on battery power but it still says 100% until you disconnect it. Then, while you're using the phone it'll adjust as you use it until it gets to the right level. This is likely what you're seeing.
If I use my phone from the moment it finishes upping to 100%, I get great battery life. I get great battery life in general and have been happy with the phone.
Of course, this might be a totally different issue where you just got a bum battery. But it's something worth considering.

I don't believe this is true. I hate to constantly be a naysayer in this thread, but this didn't seem logical to me so when my battery went to full, (when the battery is full, unplug charger text showed in the notification bar) I kept it plugged in and set it to play a couple tv episodes on full brightness while I did laundry and made dinner.
Two hours later, I first looked at the battery status while the phone was still plugged in. As expected, it was at 100%.
I unplugged the charger, waited a couple minutes, and checked again.
Still at 100%, which completely makes sense because I've never had a phone that behaved as you've described.
I also would have noticed the battery dying very early, *every single day* because my habit for the last week or so has been to plug the phone in when I go to sleep. I have an app called syncme that pulls files off my computer such as music and video while I'm sleeping, and on average it transfers about 6 gigs of data this way, every single day.
I don't know if you've ever transferred 6 gigs of data on a phone via wifi, but yes, it's not exactly battery power friendly.
My phone's always been 100% battery when I leave for work, just like my last phone was where I also plugged it in at night.
Just saying!

Actually he is pretty close to the way it operates. The way your phone gauges battery life is similar to your car with gas. When the meter reads 100%, it is really more like 98%. When the battery reaches true 100%, the phone will stop charging the battery (but will run off of USB power, not the battery). They do this to account for small variations in the many variables that affect a battery's performance (like temperature). Likewise, your phone will read 0% before the battery is truly completely drained (this is also to protect the battery - they don't like being charged to 100%, nor drained to 0%).
This could also greatly affect your previous test on battery performance. To get a more accurate result, let the phone drain to about 60%, then test the time to drop a percentage point.
What you are talking about is a suggestion that the battery meter doesn't necessarily update it's strength meter all of the time, and you even say that the phone runs off the plugged in power at this point.....

Before you discredit anyones post, you should understand how many battery chargers work, and the importance of them shutting off following a complete charge. Here is a quote regarding Li-ion battery maintenance :
Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
Many chargers have this feature built in to avoid any overheating and/or damage to the cell. I'm not saying this is the case because I have not tested whether the battery charging circuit in this particular phone, or it's charger operate, but I will say that this has been the case in MANY of it predecessors.
That being said, I think an extended battery would be a welcome addition to the options of this phone. Mine too only lasts a day at it's best. Perhaps not 1% a minute...but then again who knows?
