Battery life after initial charges- your opinions

As we all know, the Galaxy S uses a Li-Po battery.
Having previous expirience with those batteries (R/C Helicopters), i know that they require 5-10 cycles of full drain-full charge to reach full capacity and start their normal life cycle.
Not too long ago, there was a thread complaining about battery life here, but i think it was due to people checking usage time on the first or second charge only.
In this thread, i'd like to hear your opinions about battery life, but please-
Only those who passed 5 FULL drain-charge cycles, reply. We need some objective information about it.
Personally-
I'm after my 4th charge, and already seeing HUGE improvement. When i recieved it i barely managed to go through a single day, and now i'm almost 2 days since i last charged it, played some games, browsed a little, made a few calls, and i'm still over 65%.
Waiting to do 2-3 more charges and reach optimal state to see what it's worth.

Mine is a Li-Ion and lasts about a day with almost constant use.

Li-ion? what the hell?
What battery did you get?
If it's a G7, it's Li-Po

My G7 is li-ion

You are correct in that initially we were told the battery type would have been a Li-Pol.
However, since the phone's release it has now come to light that the battery is in fact a Li-Ion.
I made a post that mentions this here if you wish to have a read.

I’ve had my phone approx 2 weeks, so I’m on my 5 or 6th battery recharge. My phone has been on for 1 day 20hrs now. I’ve talked on the phone for about two hours and surfed for about ¾ of an hour. Wifi has been on all the time – Bluetooth about 3hrs. Current battery level is 70% - I must say after all the gloom and doom re the latest smartphones I’m more than happy with the battery life so far and does seem to be getting better all the time.

Wow this is too nice to read, I was starting to worry about my battery being wonky

In contrast I have had my phone since Thursday... I've charged it 4 times in 48 hours so far. I am using it a lot and am hoping I get thee performance rise soon.

I'm pretty sure it will.
When i got my phone i charged it to full, and before the day ended i needed to chrage it again.
And now:
Last charge was thursday morning (GMT+2), and now, after 2 and a half days, i still have 40%.
I could probably go on for another full day.

My first few charges barely made it through the working day, but now the phone still has plenty of charge after 24hours. Although right now is an exception, as the lady is playing Abduction on it and will probably keep at it until the battery dies
She really should get her own Galaxy S. Although we're waiting on some GPS improvements before replacing her phone, she cant afford to get lost.

Correct.... She's far too busy keeping me in check, looking after our Granddaughter and the Farm.

I got my replacement SGS today (had to send the original one back as Carphone Warehouse messed up the order so had to send everything back just to get a new SIM) and been hammering it for 14 hours, literally 80% of that running games, using WiFi, bluetooth and GPS and I only got it down to 25% and hadn't even charged it to 100% before I couldn't wait any longer. If the battery does get better after the initial charge, I will have no problem with this phone.

Further to my earlier post...
Charged the phone to full before bed last night... All of the power widget functions of two exchange email accounts and hotmail updating every hour.
So with no other use for 8 hours the battery was at 91% when I woke up. Battery status confirmed that 57% had gone on standby and 29 % on idle
So... Presuming this bsttery use is constant when idle... My phone will be down to 70 % by 24 hours with no use?
Crabby

It varies greatly according to reception.
Good network coverage= less work for the transceiver inside the device=less power drain.
It's not really constant.

Turning off 3G other than when you need it helps as well.

Is this something you do as routine? I don't know if I have the patience to do that.
And my signal was 5 bar edge signal for my 'test'.
Since this morning, I watched 90 mins of video, surfed for 10 mins and made a 5 minutes voice call on the train... By the time I got to work, the battery was at 53%.
I don't feel my phone will last my journey home at 6 tonight, so I have had to put it on charge again.
But still... on 3 days old...

Dramatic Battery Improvement with latest update.

I have changed NOTHING - I'm all stock and have always done the DRM kill in services and toggle of airplane mode.
For the first time, today, my phone is 13 hours in and still at 50 % - I can't believe it.
I used it just as much as always, sending about 50 texts, reading and responding to emails.
I EVEN LEFT THE GPS ON ALL DAY by accident.
I don't get it, but I love it!
Finally the Epic is showing me what's up!!!

Great to hear!

yea, sunday i went on a motorcycle ride and was jamming out to slacker the whole way (killed 4g since i knew i'd be outta 4g coverage on the ride) roughly 4hrs of straight slacker streaming and came home with 65% batt left and today on a normal usage day i am @ a flashing 0% batt after 10h 25m since unplugged.
wifi on during my work shift (8:30-5:30)in a low (2-3 bars) environment casual web/facebook on the pooper and smoke breaks moderate txting and about 16mins talking. FWIW i also keep mobile data and sync (facebook sync set to 3hrs) on and get quite a few emails throughout the day

Mine is working well too...just over 14 hours so far today and I'm still at 64%. This is with pretty light use, 3G on all day with sync, about 15 minutes of calling and about 15-20 texts. I'm pretty happy with my battery life, couldn't expect anything more!

This remind me of the early Samsung Moment days! So how did you treat your battery? Do you let it drain all the way down? Or do you charge it about half way like some people?

I'm pretty sure my battery has been WORSE since the update. Today my battery drained from 100-20% in less than 3 hours.
Not sure if its because I go through many deadzones throughout the day, or if its because I was using my phone a bit more than average, but was rather disappointing.
Good other users are getting better battery life though!

Whoops cancel that.
We're back to normal ****ty battery life again.
Unplugged at 6am it's now 9 and i'm at 80%. Haven't even USED IT ONCE!!! Did NOT reboot last night at all.
At this rate it's going to be dead by 6pm. Pretty sad considering like I said I've done nothing with this phone at all.

I got about fourteen hours yesterday. around half left.

Weird, I got the update last night and charged it to full around 11pm. Unplugged it and left it off the charger. Now 11 + hours later I'm still at 81%. This is with airplane toggle and drm kill

Same here..
I was at 89% when I went to sleep last night, woke up about ~7 hours later with 74%..sitting here 4 hours after waking up and i'm at 58%, time since unplugged at 10h 56m 38s

Well Now 2 hours later I'm still at the same exact battery level. Not sure what's going on here.....

Have to second that.
After update yesterday morning I charged it to 100% and 24 hours later still have 28% left (9,5 hrs of use left according to JuicePlotter).
I have full stock none-rooted. Screen brightness set to minimum (do not need it any brighter indoors), DRM and all useless to me services are shut down. I do not use JuiceDefender ( have it installed but disabled). I count myself as an average to heavy user.
Best time I got from the battery before last update was around 13 hours.

The stock battery meter in the task bar is not very accurate. I recommend Battery Indicator. There is a free version on the Market. I doesn't consume any power to run.
When I was running DG27, I usually got about 14 hours of moderate use per battery. With the DI07 update that dropped to about 6 hours per battery because of Sleep issues caused by bugs in DI07. Now with DI18, I'm getting about 16 to 18 hours of moderate use per battery.

I can't give a before and after since I just got my epic last night. However, I can say on my first day of use I have been using it on and off all day and I unplugged at 5AM, it has been a little under 9 hours. It is at 70% or so. This is 100% better than my old touch pro that wouldnt last a full day most the time.

Well Sadly I have to come back here and tell you about how f****g horrible my battery life has been the past two days.
I unplugged at 7am this morning, double checked that DRM is closed, did airplane mode, no gps, wifi ON (which is strong at my desk) - no other apps running.
After LIGHT use, (only checked a few emails) NOTHING ELSE. Here I am at 1 pm, SIX HOURS LATER and it wants to be plugged in.
This is absolute b****t.

my battery life has definitely been better since the upgrade. it was also convenient that just a day or two after i upgraded i had two extra batteries arrive. now battery life isn't even a concern.

battery is drain

so i just got the epic like 3 days ago and i noticed that it darins the battery super fast unlike the mesmerize well today i had it fully charged and i unplug it from the wall and then sat it on the counter and took a shower and then i checked it and it was already on 90%..... its only be like 5 mins give or take lol i did the calibrate trick to and everything was on 100% when i did it and right when i turned it back on after the wiping the battery it was already at 98%
so do i have a bad battery or umm is it just me lol the only thing i did on the phone was root it and turned it into EXT4 and then installed the franken rom

Get used to it. Buy spare batteries.

It is Samsung's crappy software probably. Make sure you do the airplane mode trick and kill the drm service. Also make sure any apps you installed are not misbehaving. Battery life is still going to be the worst of any phone out there though.

I have had my Epic for about two weeks(I came from a Moment, then a Transform). I havent run a stock rom since I got it. I use my own modified DK28 rom. I have no sprint bloatware. Average use my batter lasts 14-16+ hours.
Im guessing probably around 45 mins of calls, and 100+ texts, and 1 hour or so on the web/market is my average use.

I found when I first got my phone I was using it constantly checking out all the cool things it could do. Four or five hours with the display on drains it pretty fast.
The battery I have in now is showing 18h 4m since unplugged with 24% remaining. Display on time is 2hours 28 minutes, which is taking up 86% of the battery.
I purchased a wall charger with two spare batteries off ebay for $10. The two spares last almost as long as the stock battery but not quite. The wall charger seems to charge the batteries better then the USB port on the phone.
Definately get some spare batteries and make sure to carry one around with you. One fits in your wallet with no problems. As I have told people before you are basically walking around with a handheld laptop.. Be glad we get the hours out of a charge we do...
Also baffles me why people want dual core phones.. They think batteries get drained now, wait till the next generation phones come out. Unless they add much larger batteries then those things will go quick.

My battery life has gone from below average to 'functional' after rooting and installing JuiceDefender. I had Tasker running similar scripts before but eventually replaced it with JuiceDefender.
Root: Nebula 1.07 EXT4. Removal of bloated Sprint software and non-essential apps.
JuiceDefender Settings:
Controls > Data, Wifi (AutoDisable), AutoSync (Ping)
Schedules > Schedule 1hr, Night (12am --> 6 am)
Triggers > Battery 15%, SCREEN
NOTE: System Panel confirmed that CPU now idles at 1%-3% during screen-off with the expected jump to 10% during the 1hr interval syncing.

18 foot long charging cable then just keep it plugged in. Get the portable charger that you can charge while on the go
Or just close some widgets and apps using the internet and all the 4g/GPS etc. to save battery....

Well I just thought the epic use as much battery as the mesmerize and my mes was really good

Its your kernal and stuff. Stock 2.1 di18 has horrible battery life. Put the phoenix kernal in or flash stock dk28. I constantly get over 24 hours on a charge with 2:30-3:30 screen on time with stock dk28 and would be atleast 30hour charge wth the phoenix on 2.1 with same usage...

Probably the Time without signal bug in the radio firmware. Read this post for info on the workaround. My phone went from 10 hours to well over 24 hours by following these steps. The short answer is, every time you unplug the phone or reboot toggle airplane mode on for 15 seconds.

Yea battery sucks, welcome to the world of monster smrtphones. Anyway, once we get source for 2.2 (IF we ever do I should say), devs can optimize the kernel and hopefully give us better battery life. If you care about battery, stay on 2.1 and flash a custom kernel. Good luck tho, best option is rly to buy a spre battery, as has been suggested already.

I just some of the upgrades in the development forum, and even added the Midnight Rom, and my battery is doing better than what it was before. I am very impressed with the things I added to my Epic 4g and this site for all of the awesome info.

Battery suddenly drained completely

Before I left the house to go to work, my 10.1 Tab (Google I/O Limited Edition, rooted with 3.1) was at around 80%. I get home 9 hours later and the battery is completely drained. I plugged it in to the charger and turned it back on to see the battery at 1%. That just doesn't seem right to me. I can usually go about 2 days without putting it on the charger.
I've attached an image of the Battery Use graph, you can see it just drops like a cliff for no apparent reason. Has this happened to anybody else? Also, I just noticed that the time it was off (approximately 9 hours) is missing from the graph, so it only shows just under 5 hours.

I had the same issue last night. It had ~40% battery left when I went to sleep last night and this morning it wouldn't turn on, so I plugged in the charger and found the battery drained completely.

Interesting that it happened for you the same night. For me, it seemed to have happened around 5-6pm Pacific time on June 23. I don't know the exact time because I didn't have it with me at the time.

Happened the same to me a couple of weeks ago.
Battery was at 40% and overnight went to 0% and the tablet turned off.
Very weird

Came home to find mine with the screen on but completely black so you could BARELY tell it was on. Had to reboot as it wouldn't respond. When it did I only had 20% charge. I had unplugged it about 5 hrs earlier and left it with about 95% charge. Only happened once though so I haven't worried too much, maybe a similar issue though

If I had to hazard a guess.. it would probably have been a runaway process in the background somewhere that totally drained the battery. If it was the battery itself losing a charge like that, I would be worried.... When batteries discharge like that for no reason, they can actually explode... (it is rare, but possible..not trying to cause a panic).

Wouldn't a runaway process drain the battery slowly over time? This seems to have happened instantly.

I really hope i dont find mine doing this... If I watched a laptop do it I would say the battery was shot. Now that its been charged does it hold a charge just as good as it was prior?
Im jealous you got the google I/O tab, was trying to get one on ebay but to hell with spending all that money for an army of androids you wil never see in a case. I heard they were giving them away for free @ the conference...

first to make sure these power saving settigs are alright ,especially gps which will be turned on by so many location iasking apps.
i originally thought it happened twice on me . now i got to. say the first time my gps is on ,second time , the 10.1 looks no response /dead , but press power burton longer, it will be back in desktop without boot,kind of like hibernation on pc ......maybe after a quite long time no activity, 10.1 manage to hibernate itself .....just guessing

Also, CNN and USA Today apps seem to consistently get active on 1-5 hour intervals even though I disabled Notifications, etc. Anyone knows the reasoning?!

Last night I was browsing the web at about 30% battery, when my tab just clicked off out of nowhere. I wasn't able to turn it back on until I'd plugged it in. Once I got it back on it showed 1% battery.

I wouldn't suspect the ROM, but rather battery, charger, cable, port... store can check those things out for you.
In re to what you can do in theory, modern ROMs/android OS handle things pretty efficiently so I don't think it is something you have done - that is if you are not overclocking and leaving it on your oven when cooking.

Make sure you are at like 3 percent before recharge. Do that a couple times and out will restore your battery, worked for me

Wow I hope your battery worked itself out in the end. I just have another question. How long should a stock MyTouch 4G battery last?
Even before I rooted my phone and tried a bevy of roms known for their battery life, but I never get passed just about 9 hours. I used my phone moderately text messaging, surfing periodically and playing music and podcasts in between classes. I have turned off auto sync and did the battery stats wipe.
Just wondering if my expectations are too high. Nine hours is nice, it gets me through the day but then I lose it for a couple of hours in the afternoon to charge up for the remainder of the day.
Thanks again guys!

Try TDJ's CM 7.2 kang. I have gotten over 24 hours on that ROM.

Battery life is like fuel mileage. Its how you drive it. One person may get 17 mpg on a car that someone else gets 22 in. Screen on time is better to go by. A good ROM/kernel combo will get you around 4 hours screen on time. Maybe more.
