What's the difference between B and F phones again? Did I miss something? Perhaps Frank and Barney were both in charge of testing the devices on different shifts and one was always coming into work drunk.

Cheers
[Nexus One General] vegetaleb:
Perhaps it's a country serial number.

Bought my N1 just 1 week ago from a fresh batch so F is not old.

So if it's true that batteries are defective Google should make a statement here (Toyota syndrom) so we know if we should get another one
[Nexus One General] hah2110:
It isn't the battery as I have a Seidio 1600 that suffers the same fate. There is no truth to the whole "way you charge the battery deal"... If there was, every manufacturer with a LiOn battery would have much more explicit and forward instructions about charging. You also can't charge a phone for 16+ or 12+ hours as noted by this rep because the phone will stop charging once it is full.

I have a (Nexus One/Droid/G1): Nexus One

My phone is (rooted/full stock) and I'm running this ROM: Cyanogen 5.0.5.3-N1

I bought this phone (when?): Mid January

My P/N number has this letter in the end (B/F): F

Using the test, my battery has drained (%): 5%

By the way, 2 minutes of a phone call later and I'm down another 2%.

In general, my battery life is awful.
[Nexus One General] hah2110:
12:14pm - 68% (and it had been there for a good ten minutes already). Test #2. I just installed the 2.6.33_AVS_xtra kernel and am testing the new kernel. See below...

I have a (Nexus One/Droid/G1): Nexus One

My phone is (rooted/full stock) and I'm running this ROM: CM Baked Goods 1.1 w/AVS Xtra

I bought this phone (when?): Warranty replacement came this week

My P/N number has this letter in the end (B/F): Nada!

Using the test, my battery has drained (%): 3%

Seems like this kernel helps?

About Nexous One battery life

I bought my phone on feb 16th ( F phone) and the day i bought it I fully recharged it before i used it. Battery's keep memory so if you don't do the right thing when you get the phone you will not get the full potential out of the phones battery. I also have done fully discharges and recharges 2 times and month. When i take my phone off the charger at about 7:30 am and i go out to work all day i use my phone a lot for music with headphones and a lot of text messages and I'm always on 3g not edge and i have email sink on and i keep my screen about half way. At the end of the day (7pm) i have about 60% battery life left. After i get home i play with the phone a lot more and at about 11 oclock at night i have about 35% left.

I set setcpu profiles at when the battery drops past 80% i have it at max691 and min 245 and if the battery past 50% i have it at 578max 245min.

the other thing that really really helps is every time im done using anything with my phone i have the task killer widget on the home screen and i press it and it kills everything and frees up memory.

if i keep my phone on edge all day i can go all day with heavy usage and the battery will be at 75% at 7 pm and at 11pm i still have 70% so it goes down super slow on edge

hope this helps guy all add more later thanks
[Nexus One General] hah2110:
LiOn batteries don't have a memory though. What ROM are you on? Could you run our standardized test?

Sent from my Nexus One using the XDA mobile application powered by Tapatalk
[Nexus One General] DarkDvr:
Well, they do have some kind of a cell voltage range.. perhaps, and I'm not a hardware tech, they need to be "trained", as in "provided a constant medium-range voltage" for the cells to be broken in properly?

I can see that in the mechanics, how you break in your new car... What if the LiIon batteries from htc (or maybe all of them) need that first 12-24hour period of constant power to be able to retain future charges?

By the way.. one more thing I forgot to mention.. HTC support dude told me that these letters (F/B) have nothing to do with batttery life. They have 3 version of N1 - TMobile, AT&T and Google Employee. Maybe it's as simple as that? My AT&T has B.
[Nexus One General] jz9833:
This is a flawed thread because you also need to ask what ROM you are using.

Mine ends in F, and stock gave me decent battery life. It was better than my Fuze or tilt 2.

On CM 5.0.5.3 it was downright awful. I had to have a charger on me everywhere I went. I'd lose 5 to 10% on a 5 min walk from the car to my desk at work while it was on stand-by.

EM 1.8.1 give me what I'd call great battery life for how much i use my phone.

I know some batterys might be better than others, but there are much more variables to be concidered.
[Nexus One General] DarkDvr:
We do, check page 6 - there's a test and an answer template. Try it out.
[Nexus One General] hah2110:
Of course they will say this about the batteries. If they thought/knew there was a difference... they would mitigate it!

Agreed - but we do ask for the ROM in here. I'm on baked goods and that was the only one that worked with the AVS kernel.

Thanks!
[Nexus One General] ram130:
Hmm i think my battery life has now improved. I unplugged at 4am and my phone died at around 11pm. Now I had it on 2G since unplugging it and it stayed at 100% for over 3hours, even after my alarms went off!! I was like what the hell got into my battery lol...

Now around 4pm I started using it heavily, 3g on and off, listening music, streaming music and playing around with the phone. I guess your question would be, what did I do different? Well I did a full discharge. But instead of turning it back on, I put it in fast boot or what ever its called when you hold the down volume button with the power button. Its a white screen mostly with some green androids and its at full brightness. This ensured my battery was fully drained(android would shut off my phone at 2% more time).

Anyway, to conclude, I did the same thing to my second battery and its charging now. So lets see if it works again.
[Nexus One General] vegetaleb:
I don't have any battery problems as long as I don't use the screen more than 2 mins :eek:

I think HTC doesn't know how to take profit of the Amoled/battery usage, they should ask Samsung how they managed to do it with Omnia 2 and HD.

I can't play Raging Thunder 2 being afraid to loose 10% in 5 mins :(
[Nexus One General] DarkDvr:
So far it seems that it's not HTC's engineering fault.. a decent amount of people have having 36+ hour battery lives.

IMO, it's either 1) Big batch of batteries is defective or 2) we really, really have to break in the first charge exactly by the book.
[Nexus One General] larsrya8:
Since Li-Ion (and Li-Poly) batteries don't suffer from memory effects, wouldn't a complete drain and recharge only reset the battery's circuits and re-calibrate the reported State of Charge? If so, this can be performed at any time (not necessarily the first charge), and if no improvement is detected, it can assumed the battery is defective.

There are a few of these battery threads floating around (so forgive me if I simply don't remember reading this) but has anyone had only their battery replaced (not the phone) and seen an improvement?
[Nexus One General] ram130:
Had a replacement battery sent out. They are both the same.
[Nexus One General] DarkDvr:
Well, really quick I can say that battery life definitely improves overtime.

It's now week 3 and after a full day of some phone calls + PUSH email on exchange and gmail + some gps navigation.. and I have 44% left. That's with 100% screen brightness!!

(100% 3G, BT always ON, GPS always ON, SYNC Always ON).

I'd say battery lasts about twice what it lasted first week.
[Nexus One General] vegetaleb:
So ram130 it's HTC who sent you the replacement battery?

What did you tell them so they accepted?

Too bad if the replacement is weak too, it means that you don't have chance and you got another deffective one or it's just not the battery the problem but the screen management
[Nexus One General] hah2110:
HTC will send you a battery for free if you just tell them your battery sucks... No questions asked. It isn't the battery though. No way. My Seidio (and my co-workers) is bad as well.
[Nexus One General] ram130:
LOL what hah said thats basically what I did. By the way, my original stock battery seem to have improved. I don't know if its because I'm now listening music through my bluetooth headphones(over 7 hours, lasted all day) or if I'm on edge all day(3g is a lil weak in my house). I just see a improvement. So far the 2nd battery is worst though..I'm gonna keep testing and see if I'm not going crazy..:D
[Nexus One General] DMaverick50:
I wish knew what "light" and "moderate" usage meant. I text and use the internet with the middle brightness level (under halfway) and after school I'm at 30%-60%. I don't feel like I'm texting/surfing much, but who knows...
[Nexus One General] ram130:
I guess everyone should state in detail what they are doing, including but not limited to how many texts? exact mins on calls? sites browsed?(well maybe nt..), length of time on wifi, 3G & 2G? ..etc.. and battery usage after. If yall wanna do a general test, regardless of apps then do this:

Turn off phone, charge to full.

Plug it out.

Press the volume down and power button.

You should see a white screen with green androids at the bottom.

After which take a look at your time and wait 10min EXACTLY.

Turn phone on and wait until its booted. Depending on apps you have that starts with your phone, a margin of error would be around 1-2% after you manage to check your current battery %.. If no apps, then its no error.

Post the results in the following format:

*What rom or stock?

*Percentage after you turned it on back?

*How long you have the phone for(days)?

*What is your P/N on your phone?

Good Luck.

About Nexous One battery life

Ok so i took the phone off the charger at about 8 am. I own a Auto Detailing business so i use the phone as a mp3 player for about 5 hours today. Made and received about 20 calls all about 2 mins long i also used the web about 10 times for about 5 mins each time. I used the camera to take 5 pics I'm on modoca r20 rom and its now 11:00 at night and i have 50% battery life left. so total i have used my phone for over 15 hours and still have 50% left.

THE REASON MY BATTERY LIFE IS SO GOOD IS

1) I have setcpu set up like this (profiles)

charging is set to 998max 691min

sleep/standby 384max 245min

first power setting is set at 70% battery life i have it at max 768 min245

second power setting is set at 51% battery life and its 652max 245min

last is set at 30% battery life at 460max 245 min

make sure you set prefiles on and refresh on auto

The next thing I i do is set my screen brightness to the first notch

I always keep all wifi,gps,blutooth all off in less i need it

The last think i do is make sure none of my widgets auto sink i manually sink them (tweeter,android and me widget) stuff like that

And the last think i do that helps the most is i always every time I'm done with my phone i press the task manager widget (kills all apps) set on my home screen and i put the phone to sleep.

evey time i us something on my phone i kill it right after I'm done to save battery life.

My phone p/n is 99HKE002-00

and yes my phone is a F phone
[Nexus One General] nellyspageli:
i have set cpu profiles, underclocked kernel with avs, screen set to auto, 15 sec timeout, rarely use bluetooth or wi-fi, but sync and gps are always on.

my battery lasts from 7am and dies at around 5pm.

so i called up google's support and they talked to htc and they are gonna send me a battery.

if u want a battery just talk directly to htc. they google customer support was very nice and he said that htc had a really long hold time so he just took care of everything and called me back after talking to htc which took about 30-45 minuntes (after he hung up and called up htc). but on second thought maybe you do want to talk to google's support so they can wait on hold for htc for you. either way, its htc thats sending out the battery. the google rep mentioned that it was very straightforward when he talked to htc.

the rep also mentioned that if this doesn't work, they might replace my device. maybe i can get the one without the F in the part number. i wonder how this replacement will work with my engraving though. anyways the CS people are really nice from my experience.

i know my post is long and boring. sorry!
[Nexus One General] ram130:
Its kool. I found that out of the two batteries I got from htc, they are basically lasting the same. I unplug at 9am and its dead by 7pm. With moderate usage. Now I just got my bluetooth headphones and I can't stop listening music. So far my battery lasts about 5 hours with EDGE and WIFI....so much for the 20 hours music playback claim.:mad:

[Nexus One General] DarkDvr:
Decent advice, but sorry if I say that your phone is boring as hell then. And the way you're using it sounds more like a boring job (turning things off, manual everything) than an exciting use.

After 3 weeks, my battery is lasting me a full day with moderate use. I got everything turned on, brightness at full, 2 accounts PUSH email, facebook, RSS.. I just charge it every night.
[Nexus One General] hah2110:
I'm off the charger since 8am and am down to 91%... it is ridiculous. I'm on an AVS kernel and Enom with not much running in the background.
[Nexus One General] Raymond77:
On Cyanogen's 5.0.6 test ROM, and after 8 hours, with some ShoutCAST streaming (20 minutes or so) and a 25 minute call, I'm showing 74%.

The signal strength seems to make a substantial difference to battery life.

In the office that I work, Vodafone's HSPA reception is inconsistent - some days I'll have "H" shown all day (and the battery will leech power more slowly), and others it'll either sit on "3.5G" or flip between the two, all day. Today this has been the case, and it's reflected in having lost 26% power so quickly...

I was using the Alpha Desire ROMs up to a week ago or so, but battery life for me was not to good. I also have to add that I am running an Innocell 1600mAh Extended Life Battery so my times are going to be better. I did not drop to 3% until 22min. into this test. PS..market has an app called toggle display that I use when in my car to keep the screen from blanking or dimming down. Normally I use 100% display and screen dimming set at 1 min.

Just to prove the battery drain stuff is junk:

http://batteryuniversity.com/partone-12.htm
[Nexus One General] drewstiff:
I've been led to believe that a complete discharge is quite unhealthy for LiOn batteries and shouldn't be done... I have no proof of this, but I believe it was mentioned by another user on XDA recently.
[Nexus One General] hah2110:
This is accurate and shown in the article above.
[Nexus One General] drewstiff:
Ha sorry I didn't spot that before I posted. I think the chap that wrote that article is adequately qualified that we can say he knows what he's talking about.
[Nexus One General] cjacks519:
I think you're exactly right about the B/F in the part number referring to the version. My part number shows a "G" at the end. I bought my phone from a Google employee and if the HTC Support guy is right, that would make sense.
[Nexus One General] ram130:
Yea but my battery life has now improved....funny thing is I do it with my old 5 year Nokia flip phone and it still lasts me over 3 days...
[Nexus One General] vegetaleb:
In opposite to S60v5 phones the first 50% of the battery deplete fastly but the second half is 2x slower.

My battery can run for 40h now and I think that in a month from now I should get about 60h, new batteries need at lead 1-2 months to give good results and 3-4 months to give full potential
[Nexus One General] Rusty!:
Your 5 year old Nokia most likely doesn't have a Li-on battery, that's why :)
[Nexus One General] ram130:
:o oh it does. Here is a pic of the battery http://dragonsystem-web.com/catalog/images/bl-5b.jpg
[Nexus One General] DarkDvr:
Don't compare a 5 yr old flip phone to a AMOLED-powered Snapdragon super-PDA :D
[Nexus One General] DarkDvr:
Yes, that is the official specs.. I know them, I read them.. but using these badboys in practice doesn't quite agree.

I dunno, I'm monitoring my new battery (came in last night) after a 12-hour break-in. We'll see how it goes.

Also, remember when you got the N1, firs thing you saw when u opened the box was a separate sheet of manual telling you that it's crucial to let the phone charge for 12 hours without use the first time. Something made them print that paper and put it on the top - must be something to it.
[Nexus One General] DarkDvr:
Well, here's the update.

Got my new battery from Google/HTC yesterday. Turned off the phone, put it to charge for 12 hours.

In the morning, unplugged it at 9:30am. During the day I had:

- about 10 minutes of phone calls

- 70% screen brightness

- Wifi on for about an hour

- BT always on, GPS always on, 3G ONLY

- 2 emails PUSH (gmail and exchange)

- For about an hour or so played with pairing/unpairing devices with BT (remember, 70% brightness)

- Wrote some emails

- Played an online game for about 20 minutes

Overall I don't conserve energy at all. I use my phone as I please, I'm running several widgets (News/Weather/RSS), live wallpaper.. I use it like I stole it.

It's now 4:50pm, a little over 7 hours on battery, and I have 61% left. That's a projected battery life of about 17.5 hours. And if experience is any indicator, it'll improve somewhat over next week or two.

So, my advice (based on 2 batteries, one broken in, one not):

MAKE SURE you break in your battery as google advises (12 hour charge with phone off) Then you won't have to cycle anything and u'll get a really nice battery life.
[Nexus One General] sousafrui:
if you really had get a N1 recently, you sould know that what says in that peace that comes with the phone is that you should let the phone charge until the light turns green. that p. of sh instructions you are simply wrong. read yours first. .. if you have one
[Nexus One General] sousafrui:
PLEASE! !! if you're advising people be sure you have your facts right. What says in the paper that comes with N1 is that you should charge your phone UNTIL THE LIGHT TURNS GREEN. THAT'S ALL!!! DOESN'T SAY ANYTHING about number of hours or any thing related with that. i did that and a still can't take out of my battery more of 5 hours of normal use (comparing to your use, is much more intensive). there's much more to it about this battery claims than we know. finally, you say nothing about your phone being rooted. ...
[Nexus One General] elecious:
really weird

i've had no issues with my battery at all sometimes going a couple of days with no charging but today having been in meetings all the time so not much chance to play with anything suddely my battery is at 2% out of no where, the temp of the battery is over 36degrees as well, this is after a full charge this morning and when i last checked it would have been around 85-90% life left in it, then over the space of a few hours its all gone. This is also with wifi, gps, sync and the screen birhgtness all off

What could have caused this?
[Nexus One General] sousafrui:
something definitely went wrong. probably some app or service that became blocked or stop responding, and because you were not there it drained you battery. go to your configs and see what sistem drained you battery (in the menu configurations - about the phone - battery use) in there you should see what app drained the battery
[Nexus One General] DarkDvr:
Sheesh, calm down Mr Nerd Rage.

I'm simply pointing to the fact that there is a paper that recommends you to charge the phone fully before using it. To supplement that, there's also an advice from HTC Support that says it should charge for a longer period.

And regarding rooting - used it for a month on stock, now rooted and flashed AmonRa/Cyan. Didn't affect the battery life for me.

Calm the hell down.

i'm absolutely calm. don't worry about it. just don't like when people only see their side of a prob. i've been reading your posts in severeral threads, mostly about batteries, and i allready know that your battery last a whole day with everything on bla bla bla. i'm glad for you. .. really. but once in a while try to really help the others who didn't had your good luck, without puting in their minds misconceptions about this matter. and how can you say that a rooted phone is the same regarding battery use. with a rooted one you can at least use setcpu. with just this app you can probably gain 30% in the battery's life. when i received my N1, i did exactly what that paper said,... and what i get is a battery who lasts 6 h Max. only in the last 24h i fully charged my battery 2 time... about to start the third now. what about the beautiful and miraculous paper now? what happened? finally i seriously doubt that you really do a intensive use. best regards from the stressed on!
