G2 Battery Life Log - G2 and Desire Z General

G2 Battery Life Thread
Please state if you have a different battery than the 1300mAh it comes with original.
My experience
First day
Received it with 25% ~4pm
Powered off at 0% ~ 6pm
First day (first charge) - wall charge
0 - 100% from 6PM - to 11PM (it took less to charge but i left it a few more hours)
Unplugged at 11PM - played with it till around 1AM
1AM - 7AM - did not charge, it was on standby
7AM - 1:30PM - school / text / web / a few games
1:30 - 2:45PM - a few phone calls / light texting
Battery died at 0% ~ 3:00PM, at around 15-16hours with use, but also no use for about 6hours overnight.
I have installed Advanced Task Killer, whenever I end apps, it ends between 5-15.. average being around 10.. lol
but so far, my first charge from 100%-0%, without overnight use, i got around 15 hours.

drain first or charge first?
nick, you drained your batt before fully charging it.
arent the instructions always telling us how important it is to fully charge it first after you unbox it, before use?

formatting the batt is completely use up all power and then do a full min. 8h charge... best to complete this about 3 times to get full battery capacity

jus use this thing as you want.
this curiosity about battery life...
if the battery is dead, buy a new one. i dont want the phone dominating my life. i use it when and how i want. if battery cant handle it will get replaced.

That was true for NiCd batteries, which are not in use for many years. You don't need to format your battery anymore.
@nickbunyun: now try it without ATK.

Gee, I do so wish there was a G2 forum for all these G2 threads to go in hehe
http://forum.xda-developers.com/forumdisplay.php?f=750

Well, G2 or Desire Z, it's only the first charge... and whether you've fully discharged it or not at first time use, at the first charge batteries aren't at their maximum performance.
See my first charge experience:
HTC HD2: 1st - 10 hours ..... after some charge/discharge: entire day playing on it for the entire morning and texting for the rest of the day (or two days without playing)
Motorola Milestone: 1st - 6 hours ..... after some charge/discharge: same of HD2.
We'll see the battery performance only when you'll use it and you'll charge/discharge it for at least three times!
Anyway, thanks!

I started following this thought process when I got my Motorola Milestone. Sitting it in the dock to charge when not in use and overnight helped but I'm still suffering a little from battery obsession. It's a hard habit to break.

i started it with my htc magic and continued with the desire.
the battery tool it perfectly fine.
at the beginning the battery wouldnt last a day. so i bought a second charger for my work place
so first days i charged it everywhere and after some3-4 days, the battery lasted a full day.
so i started charging over night. no matter how full the battery was.
this works out perfectly well. so i will kepp it.

Battery life sucks?!

So last night was NYE. I took my phone out with me and the battery was at 100% according to Touch IT ROM.
I took 4 or 5 pictures which were terrible, the camera sucks.
I stayed at a mates and woke up this morning, the battery was down to 20%?!
I haven't even used the phone and after 16hours or so the battery was nearly dead. What the hell, am I doing something wrong.
I always thought the battery sucked but this is a joke

same here ill try to get a new one
Check if you have any applications running in the background. Do you have Wifi turned on, bluetooth? Every module that is enabled keeps sucking power. If you don't turn them off, your phone can indeed get drained pretty quick. The battery is just fine, 1500mAh isn't bad at all. Do keep in mind that - due to the big screen and many options - phones like this just don't last for a week.
Also, did you fully uncharge your battery when you first used the phone?
If the problem persists, you can always contact SE to get a new one, as it's not supposed to drain that fast.
I know on the old P990 if you didn't exit the camera app correctly it just ran in the background and drained the battery. I do a double check in the task manager every so often to ensure that nothing was left running that shouldn't be.

This is a thread from Touch HD about AE Button Plus.
I am testing this now on my X1 because I am alos not happy with MY battery life.
dingolino
the camera is not that bad, actually it's one of the bests I seen in a mobile device... anyways, don't expect to take, for example, good night photos, but actually, with good lighting the photos came really nice.
as for battery; I'm sure you shoudl have something (maybe wayfinder) running in the background, with moderate use I get 3-4 days of battery without problems; and I never let it get down 40%.
i get about 2 days max on my battery. thats with nothing running in the background, althought it does ckeck my emails every 15 mins.
shame u cant buy a bigger battery like a 3000 that would last twice as long as 4 days on one charge would be amazing
Hm.... i have another one for you guys. I was using the phone non stop for the past couple of days. Wi-fi is always on and i watch media and use opera a lot. The battery lasts for about 8 hours. When i got the phone the battery was almost dead. I did charge it but for a couple of hours only. Then i charged it overnight for 12 hours. Did the fact that i did not charge it for a long time from the box affects my battery life???

yeah, i did that with a phone i bought about 2 years ago and had to get a new battery as the original one would die after a day or 2 (should last about a week as was standard phone). i always leave a new phone on charge overnight now so i know its charged all the cells
I'm not going to say that you guys are wrong, but...
This phone, does not need to be fully drained the first time you use it, nor does it need to be fully charged. That was only an issue on older batteries, it's not an issue anymore.
I also believe it says so in the manual somewhere So, I'm guessing you guys had some defect batteries, cuz it's not an issue with the battery thats in the X1.
are you using Itjes latest HD based rom?
I found I got really bad battery life out of it for a couple of days till I let it run down to under 10% then charged it again. It's working fine now.

I heard the same thing from a couple of people. Older batteries had that problem but modern ones don't. I just wanted to make sure =P
u might be right. like i said it was about 2 years ago it happened to my phone. but why take the risk
The only thing I had on was wifi and check mail every 30minutes.
I only use general useage (8 pictures and a few messages)
but that was it. I dont understand. I charged it for 20mins and its gone from 20% to 60%.
7hours later its only on 50%. Strange thing is, my phone has been on a radiator all day and it hasnt last that much charge.
Last night it was freezing -4c outside and wasnt that warm inside, then I slept in a cold room. I wonder if heat has anything to do with it :S

Did you flash your phone recently? was the battery at full before you flashed it? it's been reported as a problem on other phones (I remember the UNI used to do this) that if you flashed when the battery wasn't at full it messed up the power levels.

Mine was crap the first few days. I read somewhere on this forum to run battery to zero and charge overnight with the phone off. Mine now lasts all day and is recharged each night.
Just a sidetrack with regards to batteries...
When I charge my X1 with the device turned on, the battery tends to heat up till even the casing is hot to the touch. Is anyone else encountering the same thing?
However, when the device is off while charging, the battery doesn't heat up.
Weird...
It depends on what applications you've installed.... Touch flo drains it like hell.
My phone looks like this.
I use SE panel 1, no other gimmicks.
Pocket player for music 2 hrs each day.
15 min of video here and there.
2 hrs of phone calls, and a hell a lot of messages, which means keeping on switching the phone from potrait to landscape and so on...
SPB phone suite.
SPB wallet.
SPB Wireless manager.
I get a solid 2 days with about 15% remaining at the end of the second day...

As much as possible put the phone in sleep mode when you charge the battery. And the battery gets more heated up when charging over USB.
Hi!
I had the same problem some days ago. Even if the X1 slept on my desk with no application running, after 2 days the battery was empty.
I thought about what I installed last and deinstalled Batti. And now the battery lives much longer.
Btw... does anyone know a good app to show the status of the battery? Or how I can show it instead of the clock?
Batti was great but charging every second day was not.

How I fixed My Battery drain

Hi!
I've made a n interesting discovery with my battery.
3 weekends i have drained my battery until it shut itselfs off, and then i have charged it up again. And now i realy can live with my HD2 battery life.
When i come home from work i have about 80% and now as i write i have 76% left at 20.44.
Before i would have about 30-40% left at this time, i have never drained my battery before to 0, so when it happens the first time i noticed a slightly improvement. So the next weekend i did the same, and this last weekend i unplugged my charger at 06.00 in the friday morning and did not charge before sunday morning at 10.00. And for me THAT's a BIG/HUGE improvement.
Glad you resolved your issues .
I've found that having any kind of TSR apps installed on the device memory instead of the storage card, has made the battery life livable on my HD2 .

Hey guys!
I really need to try this. my battery life is just so pathetic.I hope it works for me too.
TSR - Terminate and Stay Resident.
Anything like G-Alarm/G-Profile, task managers etc. Any program that stays on or runs in the background I install to the phones memory. I think there is increased battery drain caused by accessing the storage card constantly IMO, so installing stuff like the above has made battery last 48hrs no problems. I too like to do a couple of full drain and recharge cycles a month .
I'm willing to bet that the majority of people who have battery issue probably has like a **** load of apps installed and/or unaware that some of their apps that they installed were running in the background. I've had the t8585 and the newer t9193 and never had any battery issue. The battery will easily last me 50hrs with light-to-moderate usage.
i can only confirm this.
after draining ur battery a couple of times, u need to fully charge it and it lasts longer than the first few days with the HD2
from new my battery life was totally useless. would barely last until 9pm no matter what i did.
two weeks ago my phone decided to forget it's pin lock number so had no choice but to hard reset the phone. since then i get a couple of days out of it and that's with heavy texting and web browsing.
i loved the phone before but battery life drove me up the wall but now i'm getting more life out of it i am now loving the device!
On the first couple of days I had the phone I had <40% by the end of the day but now even though I use my phone alot more I find I get to bedtime with ~50%
charging it unpowered after the drain also helps. (like with USB not the charger)
Most battery "manuals" state that completely draining the battery from time to time followed by full recharge is considered "good exercise" for the batt

Not to hijack the thread, just wondering if you're the talented skin designer that created some of the BEST for Wizbar? I still use them on all my HP PDA's
Few days ago i bought my HD2, and before that i saw problems about battery life on this forum.
When i bought it I drain the battery until he died, then i left him turned off and let him recharge over night (cca 8h). In the morning I turned him on and i used him all day max...and in the end of the day battery died at 23h, again, when he was off I let him chargeing over night (cca 8h). In the morning I turned him on and used him average, at evening, 23h, the battery was on 54%, I went to sleep and in the morning (after 7 hours) the battery was 52%.
2% in 7 hourse is very good...and 50% over day. I'm ok with that

All that does for Lithium-Ion batteries is to reset the "estimated remaining charge" circuit. It wont increase the available battery life it just makes the battery report more accurately as to its remaining charge.

i use energy rom with the gtx, and my battery life is so bad. it hardly reach one day!!
when i sleep at +- 10 p.m, i have 90%
when i get back from school( as most school here don't allow mobile phone), it left at 70/60 %, i get back from school at around 2.00 pm, i don't have any program running, gprs off, running at edge, i use 2.12 radio, how can you guys achieve 2 days?

energy rom's use a lot of power. i didnt knew that untill i flashed the Anastasia rom ( link ) battery life is great and it looks better than energy imo. and it easy runs 2 days for me
I've been very annoyed at the rapid battery loss with Dutty's series of excellent ROMs.
I started from scratch and didn't install any apps to the Storage Card just to be absolutely sure. I even put the phone into Flight Mode.
Tonight I finally nailed the culprit for the huge drain (we're talking 50% in a few hours): it was a 16GB "Memory2Go" SDHC card. With the card removed, I lost just a few percent over a couple of hours.
I also don't get the same drain with an 8GB Sandisk card installed.
Any ideas on how to get the 16GB card to play nicely?

I NEED HELP!!!! My battery gets empty too fast

I've been reading and readind all the post i can get and tried do deactivate al the functions i could remember but without any good results. My phone isn't rooted and it is as it came ( beside some apps I've installed). I don't know what to do more. PLEASE give me some more advices.

ok. thanks for the imput
can you give me the idea of how much time should i expect to complete charge of a nexus one battery, while using it. mine takes 2 or at most 3 h. i think ot is fast. should i be worried?
I prefer to charge it while it's off. Using it while it's charging emits more heat than usual, thus being bad for the battery :x.
You don't need to turn it off to charge it, it's true it may become warmer but it's far from being dangerous to the phone and won't harm the battery. How long is your battery lasting? You said you're new to Android so I'm not sure if you've had a smart phone before but it's typical for a smart phone to last between 8-24 hours depending on how much you use it. It will last less than that if you're streaming music and youtube all day.
yesterday my phone lasted 5 h at most. and yes i'm a newbe.
during last night after emptied
my battery i did a full charge while the phone was off. lets see today
The screen is a battery eater, avoid watching movies or playing games or it will last 5h. My N1 battery can last 4 days if I don't turn on the screen but if I turn it ON it loses 1% every 2min
For better battery results:
-Use a task manager/killer app from the Market to kill running apps
-Use Undervolted Kernel (Root needed)
-Use 2G only when you don't need 3G
-Don't use CM Roms because they eat more battery than other Roms
-So far the best Rom for battery is the Desire Rom(but still no BT)
the thing that bothers the most is that 90% of my battery use goes to tbe screen. so it doesn't matter how well i tweek my phone... do you get my point.
i don't watch movies in it. i use a taskmanager as you said, and since yesterday stop using 3G (and i think I'm seeing some diference). it's amazing when you say 4 days (with the screen tirn off) - but to me is a little hard to not using it: I bought this phone so i don't need to allways bring my laptop with me. about what you said about the roms i don't feel able to mess with that.
1. Choice of wallpaper matters. Experiment to see which ones use less battery power for you. (e.g. Magic Smoke live wallpaper is good for saving battery power.)
2. Brightness of screen setting important. NO auto. Select lowest possible manual setting & you still have plenty of light. You can raise level for those instantces when you need extra light.
3. GPS off, except when needed.
4. Seidio 3200 mah battery with provided cover is excellent. No battery longevity problems ever since using this battery. (also using other tips mentioned here)
5. Bluetooth always on, no problem.
6. Wi-Fi on when you need it.
7. 2G/3G switching unnecessary.
8. After total discharge or new battery, let charge at least 12-24 hrs. (this particularly applies to the first few cycles of battery use) After several total discharge/recharge cycles, recharge whenever. Nothing is gained by letting battery totally discharge after that. If you have correctly charged your battery to 100%, remove it, reinsert it, & find % power loss, you may have battery with leak. Replace battery.
I have tried many methods of saving battery, and by far
JUICE DEFENDER
is the best method I have tried yet.
It basically makes it so your APN(Data) only turns on once ever 15 minutes Or when the screen is on.
You can adjust settigns with pay version, but the free version is VERY good still..
Combined with the 850mv undervolted kernels I am draining maybe 3% per hour on average with some light use(regular amount for me, light for most)
I would give it a try. No risk with it.

can you elaborate on that what implicated? and what do i have to? doesn't the phone need to be rooted?
I'm starting to see the light at the end of the tunel. usually by this hour I'm beginning to use my second battery charge of the day. right now I'm at 50% of the charge i made last night (after totally emptied the battery made a full charge with the phone turned of). deactivated GPS, sinc, using only 2G and a lot of self motivation to not touch the screen. it's better, but still made my order at expansys for a backup battery and a dock to use at home with the possibility to charge the spare battery.
today my battery had juice for 13h. from 9am to 10pm. it's a improvement. .. really is.

Dude, my advice - don't worry too much about wallpaper/wifi/BT and all that.
Here's my short battery story.. I bought it 3 weeks ago and no matter what I did, it'd last me 4-6 hours and die. No matter what I did with brightness/WiFi, it made little impact on the battery life.
Now, 3 weeks later, I have:
100% stock AT&T N1
Only 3G, never 2G
100% brightness
more phone calls per day
Wifi/BT/GPS always ON
Always use live wallpaper (gray neural network)
2 email accounts on PUSH (exchange + gmail)
And my battery lasts me 8am to 10pm easy. I just charge it overnight.
So, cycle it (full, complete drain) 1-3 times, then just use it normally. It'll be much better after 2 weeks or so. Also, HTC tech recommended me to use "trickle" charge (charge it with USB, not AC).

hope you're right. mine is now 2 weeks old. i though that was better to charge using AC. i had another cellular some years ago and the battery got messed up because the i charged very often with the computer through usb. are you sure?

Battery life experiences

Just starting a thread for battery life experience as people use the phone. Mine is pretty freakin' great right now, but I'll post some initial results after I get home later tonight. I finished charging to 100% almost 2 hours ago, and with just a bit of usage (maybe 10 minutes total screen on time) I still am at 100%. Though, we know that it sometimes takes a long time to drop from 100% to 90%.
What are other people's experiences? Please post display on time in battery stats, as that gives a good feel for how much you're actually using the phone.
Unplugged it at 6:30am with a full charge.
Took it to work, I put it in airplane mode when I'm in the building because I don't get a signal and don't want the radio searching for a signal and wasting power. GPS/Bluetooth/Wifi are all turned off. I turn the radio back on when I'm out of the building, and I'd estimate it's been on 2 hours since it was charged.
Have watched the latest episode of Family Guy and started on the latest episode of Dexter using Rock Player.
I estimate the screen has been on for about 4 hours. I can only estimate because I had to plug the phone in to transfer a file a couple hours ago which reset the stats.
I've downloaded and installed about 20-30 apps today over 3G networks.
At the current time of 3:15pm (8 hours 45 minutes since full charge), I have 30% of the battery left.
I think you're supposed to do a full charge and full discharge so the phone can "calibrate" the battery meter, which I have not done yet, but so far I'm very pleased. Puts my 2 yr old G1's battery life to shame...
Yeah it sounds decent. A bit better than my Nexus One was.
I would say it is on par with the Nexus One. Should get you through the day but you will be plugging it in at night. It is comparable to most android phones.
Sent from my T-Mobile G2 using XDA App
Without explaining a bunch of boring details, it's definitely better than my N1 so far. Charged it up right after getting it from the UPS guy today for a couple of hours while I took a nap.
We'll just have to wait and see after a few days of use, charges and discharges. Looking great so far, though!
Played around with it at the store today, came in at 3 p.m after school. The demo unit was already at 45% when I got it, surfed the web for about half an hour, downloaded an app, watched YouTube for about 5 minutes and the phone died at about 4:30.
Not really impressed, but its an Android phone. Hopefully it can be better, the good thing is that the web browser is a lot faster than my iPhone 4. That's what keeping me on returning the iPhone, and it starts up a lot faster as well. Took about 20 seconds to boot up after the phone died on me, and the rep charged it.
Definitely will be needing to charge it every night.
3 hr bike ride with music playing used about %50 of the bat. So its way better then my G1 but not as good as my Iphone 2g.
I'm getting much better battery life then I was getting on the G1....love this phone

How about someone download Battery Left widget and tell us what it says.
Will vary by user but it will be more accurate with remaining battery life.
So far the battery life on mine is terrible compared to my nexus one, and that was terrible as well.
I woke up 10am, phone on the charger, took it off, around 2pm made two phone calls. Went to work at 5pm, phone's battery was at 23% around 7pm. My nexus one around that point would be at ~50%. So far I'm not impressed with this phone, more work could have went into it.
I loaded a few webpages... did a video chat with someone on Fring for about a minute (lol), downloaded a few apps, had a few phone calls... one lasting about 10 minutes... and after being off the charger for 5 and a half hours.. i'm at 44 percent power... this is my first android device so I'm not sure if that's good or bad
Have you all that are reporting poor battery life done the full-charge/full-discharge thing to "calibrate" the battery meter. I'm not sure that it really matters, but I'm assuming it does since battery info is one of the things you can wipe in the recovery roms.
I'm still extremely pleased with my battery life.
I got the phone yesterday and played with it right out of the box till it was at 5% battery... i plugged it in lastnight and let it fully charge and i unplugged it at 6:15am this mornining... i used the gps to get to work to see how it was... i have watched videos on youtube, gone on the internet, checked and sent emails and texts, downloaded some apps... and played around with it today... i had it plugged into the computer thru usb for approx 5 min tops to set up some media files... and as of now at 3:33pm my battery is at 50%
Opening mine at 930/10pm, heavily used it to burn it to 0% and did that by 12/1230am. Charged it to 100% by 330am. Played with it a bit then went to bed, left it unplugged. Woke up today and burned it to 0% by 330pm. It's charging right now and we'll see how it goes throughout tonight. It will get a bit of pocket time so I'll get a real feel for the battery life.
Took mine off the charger at 7am throught the day had 20 incoming/outgoing calls all lasted at least 2or 3 mins each, downloaded a couple of apps, checked facebook and twitter a few times. showed it off to some friends and now it is almost 5:00 and still have 60% battery, so I am impressed especially since I had a G1 before this

They aren't changing them long enough. Lithium ion batteries don't have to be trained like the older style ones. Other other culprit could be the batterystats.bin but you can't access or delete that without root. Jut discharge the battery till it powers off and charge for 4-6 hrs.
charged mine last night while tethered to my laptop browsing - took it off about midnight
this morning the alarm sound (pre-alarm 5 minutes, full alarm for 10 mins and never woke me btw), spent about 2 hours+ talking, browsed the web for maybe 15 minutes, downloaded a few apps from the market and ran a few quadrant benchmark test - it's now almost 6:00PM and it's at 40% -
i'm happy with that - and from experience with my MT3G and the vibrant, battery life should improve with some cycling or useage

leave it on the charger for 4-6 hours after its full or just to charge it from empty to full?
I'm very glad to hear about the excellent battery life. A friend of mine has even reported his phone being on for a full day and still having battery life left.
People make sure that you charge up your battery fully before turning the phone on. It's better to be safe than sorry. I know people say it does not matter but otherwise the battery won't be accurate if you just turn it on out of the box.
10 hours and some change later after normal phone usage and I had to charge it... I'm impressed to say the least

[Q] Does battery get better after a day? If not, what can I do?

So I got my G2 yesterday at about 4:30. I LOVE it, absolutely (a bit of a weak hinge, and I had a random reboot and trouble starting WiFi at first, but it's seriously fantastic). But I'm having problems with the battery. At the store the guy turned it on and handed it to me, and I used it on the way home to the point that, by about 1.5 or 2 hours after turning it on the first time, it was at about 15% battery. So I started charging it, and then read an article online that it should be discharged, so I unplugged it after it went up about 4 or 5% in battery life to 16% and used it a bit more to drain it all the way. Then I read a different one saying you should never discharge it because it's Lithium Ion, and so I turned it off until I could get to the charger and then charged it and left it charging until I woke up at 6. Then I unplugged it, used it for about 20 minutes in the morning, and turned it off. I turned it back on at 3 today, used it mildly (Angry Birds, an emulator, and the camera, but couldn't get data access except very intermittent EDGE, no Wifi or GPS enabled) until 4:10, and noticed that it was at 65% battery life. The screen is on automatic brightness, and I have animations and a live background, but those are my only concessions. It said 45% of battery use was Android and that was the highest thing, I think display was only second or third (unlike my parents' Vibrants where it's like 66% display).
So that's 1.5 hours for a third of the battery, with moderate usage (I would argue that no data or GPS or wifi or internet usage at all is very moderate). So, on average, I could expect to get 4.5 hours of battery life? At one point it went from 55m unplugged to 1:07 unplugged and the battery went down about 10%. That's worse than my parents' Vibrants, and they say they didn't do anything to train their battery--and I've seen reports, especially on here, of people getting 10 or more hours of use with more usage than I had. I know you train Android and not the battery, but still, I have seen SUCH conflicting information on this that I don't even think it'd be helpful to search anymore (and trust me, I have). So does anyone know about this, definitively? Does the battery life get better after I charge it and discharge it for several days? Should I let it go down to a full discharge or keep it above 35-40%? Does it harm it to keep it plugged in after it finishes charging, or does it have a thing to stop charging the battery and just run off AC once it reaches 100%? Is it too late to train my battery now? Are there any official or reliable large-capacity ones for the G2, like a 1750 mAh?
Thanks,
Rocky
Don't trust the battery meter. Fully charge your phone up, and it runs for forever. I've gone days where I unplugged it at 7:30 AM, and didn't plug it back in until 5:30 AM, and the battery was still above 20%. That was a day of fairly light usage, so that's not necessarily typical; with my normal usage (which is somewhat heavy), it's at about 30% by the time I plug it in at around 10:00 PM. The only time this isn't true is when I go for hours on an Angry Birds marathon :S
I have noticed on all my android phones that the first couple charges seem to drop much faster and each subsequent charge seems to get better. I run mine all day with push work email and vibrate all day and am upset when it is below 65% at 10PM and I unplug it at 7:30 am each day.
But did you guys do the same thing I did (15% then charge overnight) and then get around the same life, on your first day? Is it likely my short charge the first time did any damage? And are there any apps to provide a more accurate battery meter, preferably in place of the stock one?
Thanks,
Rocky
I did nothing special. I put it on charge when I got it but did not do a full charge before leaving work and going home. Did a full charge that night.
I plug it in each night when I go to bed and it has been as high at 70% and as low as 30% depending on how much phone and data time I spent that day.
I unplugged mine today at 7:36am and at 4:06PM it is at 79%.
I use battery indicator from the market. It does not poll and only listens for the OS battery change broadcast so it does not use up battery by running. Some poll and as such use battery to report.
The general thing about Lithium Batteries is that a full discharge is bad if the voltage level goes below a certain point to where the onboard circuits will disable that battery permanently. Most of the time the boards only do that if it's left discharged for a long time I believe, correct me if I'm wrong here.
Ideally, you're not supposed to turn on the phone when you got it. You were supposed to charge it till green and then you could use it, but I'm pretty sure not everyone can resist the temptation to turn on such an awesome phone . The battery life will blow the first week of use. I don't know why, but it just does; you'd have to break in that battery. Then the general rule I follow is to perform a full discharge once a month and then do a full recharge.
I also placed my phone on GSM AUTO PRL but for doing that I just exchanged some low 3G signal threshold for Edge; the extra battery life I got though is just that much more useful to me. Using WCDMA Preferred, the phone just wasted so much
To answer your questions, my experiences with the N1, Vibrant, and G2... battery life just blows in the beginning but gets better with use. The first charge you did shouldn't have damaged the battery but I think you may have wasted 2 of the possible 400-500 cycles that battery is capable of doing what you did. Finally, I use BatteryTime by Motalen for the status bar battery indicator which shows the % left.
Yeah, it just sucks because the guy at the store literally put my SIM card in and then turned it on and handed it to me. I probably wouldn't have turned it on until it had charged if he hadn't, or at least I like to think so.
So it's good to do the discharge thing once a month, and probably not bad for the battery to let it dip down as long as I don't prolong it too much? And I'm okay to just charge it and use it during the day, basically, from now on?
Does battstat poll the battery or just listen?

Nonsense. The battery runs down fast the first week because you got a new toy and you can't help playing with it all the time. After a while the novelty wears off and you use it a lot less. The battery doesnt just magically get better

See but if that's true then I can only expect 4.5-5 hours of battery life which is not what the G2's supposed to get. Which means either I DID mess up my battery instead of just running through some cycles, or I have a bad one, but not horribly bad, just for some reason only like 60% as good as everyone else's. I do agree about the novelty thing (it's my first smartphone), but understand I was not really doing all that much when I drained my battery like I said. Not nearly as much as it should take.

Those damn birds aren't content to kill pigs; they have to go after our batteries too!

I'm hoping that's the case. I remember receiving my N1 and I got to relive my childhood days for 12 straight hours. Regardless it's pretty sad to say that I leave my G2 at home while at work and it's down from 100% to ~60% with Wifi on (and with it staying on in the advanced settings) and GSM Auto PRL; I work a 8 hours shift. I left my N1 at home to mess with my G2 at work and my N1 went from 100% to ~80%.
Those 100 extra milliamphrs shouldn't do that much of a difference. Not to mention the N1 is slower and on a 65nm process. Did I also mention that both my G2 and N1 run the same services and 3G is also disabled on my G2 since I don't have my new SIM activated yet? Also, Latitude is always on for my N1.
It's just my experience though. I'll give this a good thorough test when I get the time. That or pony up for an extended battery.
On the other hand, my wife's GalaS is doing just fine in terms of battery life. Matching my N1 with the same settings and services.
