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?

Just want to share my experience of 'best' charging method that can maximize the battery life of my Nexus one.
Firstly, let me introduce my equip:
- Machine: Nexus one
- Rom: FRF91 Stock, Deodexed, rooted, busybox... (Geo411m)
- Kernel: intersectRaven's 2.6.35_AVS-925mV_CFS_20100802_1056.zip
- Control: SetCPU, Interactive: 245-960Mhz when on, and 245-245 when screen off
The key method of obtaining max. battery life is the 'GOLDEN' time from 100% drop down to 99%. Once the battery shows dropping from 100 to 99%, the dropping speed is quite stably fast onwards
So, how to retain 100% longer before dropping to 99%? Below are the steps that really work for me:
1) Charge the phone to green light, some where between 90% and 100% (say: 95%)
2) Disconnect USB charging cable
3) Turn off the phone
4) Connect USB charging cable and charge the phone, it should show orange light
5) Set a timer, remember to *ONLY charge the phone for around 20-25mins*
6) The concept is NOT to charge the phone until you get green light. In order words, you need to charge the phone from 95% for 20-25mins where the light is kept ORANGE with the phone turned off!!!
7) After 20-25mins, disconnect USB cable and power on your nexus phone
8) You are done and the battery should last longer before dropping to 99%
9) Time in step (5) depends, you need to trial-&-error
For my experience, I normally charge the phone before I sleep and disconnect the charger. In the morning when I get up, it usually shows around 95% of battery. Then, I power off the phone and charge it. And then I take breakfast, bla bla bla ~ and after around 20mins, disconnect the charger and go to work. The battery can retain 100% for around 30mins of continuous web browsing, facebooking... and when I reach my office, sometimes, the battery still shows 100% !!!
So, above is my experience of how to maximize the 100% retaining time.
Please feel free to try and share with us whether it really works for you
Great advice.
Personally, I can't really be bothered with going out of my way to be overly concerned about battery life. I don't play games on my phone -- that will change when Angry Birds is released for Android -- nor do I watch movies, and I don't really do too much web browsing. Sometimes I listen to music, but not often.
I can go 12-14 hours of normal use (mostly Twitter and text messaging) and that will put me around 45-50%. I'm never somewhere that I can't charge the phone if I need to; USB at work, regular charge at home, and a charger in the car.
All of these tips and tricks for extending battery life are neat, but why bother?
^ Well looking at your usage, and the plenty charging points, of course you dont care. However, some ppl browse a lot, play games, so every last inch of battery life means something.
I just keep spare batteries in my pockets =D
I will try your golden tips.. then I will write my thoughts.
I thank you for sharing.
Screwing up the battery meter does not get you more battery life, period, and I suspect your shenanigans here is doing that. The battery has a set capacity, it's not going to charge more than that.
The Nexus One and a lot of other modern phones with modern batteries DO NOT trickle charge, they charge to 100% and STOP charging. When the phone drops to a certain limit, it charges more. Repeat as long as it's on the charger. This is why you might see it "drop a few percent" when you pull the charger.
Yea this sounds like a huge placebo effect.
Well I just did this, been off charger for over an hour.. still 100% after over an hour and two reboots.
At 1378mAh right now, didn't get a reading straight after first reboot unfortunately.
I'm also trialing autorun killer. Disabled a free services I don't use.. seemingly increased startup time.
heya,
Don't you mean decreased startup time?

Yeah, that's what I mean.

How do you figure out your mAh level? Spare parts only shows me mV.

This is placebo. In the OP you even say after it finally drops to 99% it drops fast after that. It's because the phone wasn't at 100% all that time. It was giving you a false reading from messing with the charging pattern.
The best way I've found to charge the phone is to delete the battery stats, turn the phone off, and charge it until it's green. I get a great day of battery life with the phone that way.

Totally agree...I just charge when & where necessary and never worry about it! Don't have the time and it seems to last long enough for me to work & play
I had already discovered this and was looking for a fool proof way but I guess you beat me to it. Happens when you traveling alot. For me, I have gotten over 1500mAh more than once..some times 100% would last me half a day too. So it's worth it, my question is whether or not this is bad for your battery? or long term battery life.

I'm fairly sure that the Milliampere-hour (mAh) is the capacity of the battery (the amount of energy it will store). How can you get "over 1500mAh" on a 1400 mAh battery? None of you are making any sense what so ever. You can't get more energy out of a battery by charging it a specific way. If I gave you a bucket that held 10lbs of sand and you filled it with 8lbs of sand and waited a few minutes then started filling the rest slowly, it wont hold more sand. This is nothing more than a placebo effect. The only way to get more time from a battery is to reduce the amount of consumption. The only way to do that is to use your phone less or make your hardware use the battery less such as undervolting your CPU. I tried for the longest time to explain to people that underclocking your CPU does absolutely nothing. If you're still running at the same voltage you're still consuming the same amount of power.
Stop messing around with the battery and the battery stats.
Could someone please use the phone until it goes off in the evening? What percentage is shown on the batteryicon when it goes off? 20% or what?

I have been using ultimate juice defender and battery life has doubled with usual usage. Maybe this can be considered as an alternative to longer battery life
Sent from my Nexus One using Tapatalk
I have two Arias, one freshly rooted with the rooted stock ROM and one running attn1's FR008 flashed straight from the freshly rooted state. The only additional app installed is BattStatt, so I can easily monitor battery state. One battery is new, with only a few cycles (over about a week) and one battery is older, purchased in August.
Over the next few nights I will be doing an experiment. Both phones will be on, same settings for GPS, WiFi, Data, and Bluetooth. They will only have the displays set on about every hour or so to check battery states. The following night, the test will be done again, with the batteries swapped. I will then run the test again with WiFi on, with intermittant connections due to my work environment.
I expect to update this thread after each night's experiment.
The first night is an exception, I'm comparing my normal ROM (loaded with apps, widgets, and running Tasker) My first night has been interesting...one running freshly rooted is still 100% after 1.5 hours. The FR008 with many apps is down to 89% (note that this is the older battery). Perhaps at the 4 hour mark, I shall swap them. It would be nice to do this with 2 new batteries, but I have what I have.
This is being done to lay rest to the claim that one ROM gives better battery life over another. Seems like it is going to be conclusive if the first night is any indication. Perhaps we'll see what app is the culprit? (Widgets??Tasker??)
Phone calls?
Interesting article regarding battery life
Interesting experiment !
Just FYI - an provocative article :
Your Battery Gauge Is Lying To You:
Everything You Need To Know About Bump Charging
And Inconsistent Battery Drain
No phone calls on either. Just to be fair, since one is without a sim card, both of them have data turned off.
At the 4 hour mark, the original rooted ROM is still at 100% and the FR008 with mucho is at 82%. I have swapped batteries.
This gave me an opportunity to race bootups. The stock ROM booted up and was usable before the FR008 (with UOT cooked startup bootup animation) even got to the dancing droid. Makes me want to undo that to see if that is slowing down the bootup.
I am eager to do this full swing with clean ROMs tomorrow. I shall make a backup of the FR008 ROM then go back to the aria_shipped_rooted_signed.zip
(found at http://forum.xda-developers.com/showthread.php?t=783508&highlight=Original+ROM). I will then flash FR008, adding only a widget for easy monitoring of battery levels, BattStatt.
This experiment is going to have to wait. Part 2 of last night's experiment indicated that my older battery drains fast in either device/ROM. The article linked in this thread is good reading. Thanks for that info.
My last Intruder was a Grumman A-6E.
Awesome idea
What a great idea - I hate the battery life on my Aria, and have tried multiple ROMs and multiple battery programs. I look forward to watching your progress with different settings and ongoing informational reports

I have two Aria phones - both the same age
one is stock 2.1
one is FR008
I set them both up the same - running HTC Sense -
I set the phones down (while I slept) for 8 hours
the stock phone drained 10%
the FR008 phone drained 43%
Did it twice
I know its not a 'real' test , but it does make you go hrmmmmmmmm.

You set the phone down for 8 hours and your phone drained 57% battery on idle for FR008? I find that very hard to believe because I have set my phone down over night and it drained 2% of my battery if even that. FR008 has shown the best battery life to me over the entire FR series. As of right now, my battery has been off charger for 6 hours, and Ive used the internet, wifi, and light texting with my battery at 100% still.
Edit: Im also using SetCPU...I dont know how much of a difference that would make, but there should be a difference. Try using SetCPU
FR008 is a battery drainer from hell. I just accept it.
SetCPU slows down my phone to epic proportions--no thanks.

let me try this - i am currently at 100% -
its 8:17 AM PST
I will let it sit 'idle' on my desk at work - off charge.
in one hour - i estimate that it will have dropped 2% now (new ROM)
I will report back

I'm hitting 41 hours and still have 19% battery life. I noticed it took around 10 full charges before my phone started to get this great battery life. I've been using it as normal and even listened to howard stern for a couple of hours yesterday. Talked on the phone a bunch of times around 30 texts and even used my 4g for a few minutes. I've never had an andorid phone last this long for me even when I had my Optimus S which I thought was awesome.
Anyone else getting this awesome battery life? I'll post screen shots when its about dead as I dont want to plug the phone into usb to get the pics.

I would investigate as that shouldnt be. My shift lasts almost 2.5x my hero. I bet if I had your phone in front of my I could find out whats killing it soo fast.
Is your phone getting hot? I would do a full system wipe and start over from scratch and see if it doesnt get better after you try the things I've listed below. Note, I didnt have this great of battery life until 6 days after I purchased the phone and charged and discharged numerous times. The first few days the battery life was not good at all.
A little list of things to do, check and or disable;
1. Use spare parts and find out whats killing your battery ie partial wake usage, cpu etc.
2. Turn your window animations from all to only some animations
3. Turn off automatic display and keep it around 20-30%
4. I have auto sync off on all my appz (E-mail, Gmail, Facebook etc.). I update my E-mail and such manually.
5. Turn off data when not using it. I find data accounts for around 15-25% of juice used and thats just when on idle.
6. Only use widgets on the homescreen if you really have to (Running widgets use a lot of power over time)
7. Use Android Hackers tool from the market and it will break down how long your cpu was in a certain state. ie my cpu spent 65% at 245mhz and 28% at 806mhz.
8. Keep off 4G, Bluetooth, wirless networks for location and GPS if not using it (GPS uses less power than wireless networks and is more accurate anyway) I assigned Quick Settings to open when I hold down the search button. That makes it easy to enable/disable any of these setting within seconds.
9. Turn off google talk and make sure it doesnt sign in automatically (most people dont realise this)
10. Turn screen timeout to 15 or 30 seconds (if longer your phone can keep the display on accidentally while in your pocket if a button is pressed, wasting power)
11. Dont use a task killer unless its to kill an app you know drains your battery and therefore must be closed to save juice
12. Check your apps. Some apps keep using cpu etc because they were not programed correctly. (some appz I've found to drain my battery are; Yahoo Mail, Craigslist, AndTorrent and the market if a download is hung up. There are a few others I cant remember off the top of my head) If your phone is getting hot for no apparent reason this may be the cause.
13. Calibrate your battery by bump charging (charge your phone till its full while on, turn it off and charge till its full again. Then bump charge it around 5-7 times) Wipe battery stats if applicable. If you have a car charger, plug your phone in on the way to work to account for the little bit of drain that occurs once the phone is fully charged yet still on the charger.
Remember you can get china made batteries for very cheap. I paid $12 for 2 batteries and a wall charger off ebay. This phone uses the same batteries as the Hero and Evo by the way.

yahoo mail DESTROYED my battery life on my hero so i havent used it in forever...sad to see it still had that problem....also I stopped using any battery widgets that show the exact percentage (as these are usually wrong anyway) and went back to using stock browser (Miren browser, while I really liked it, was eating my...)....i now check my battery through the settings....I was having varying battery life but after recalibrating by letting it die all the way then charging it up full i most recently got like 30 hours off the charger with moderate use and got down to 10%....coulda probably squeezed out a few more hours too if i left it idle....not too bad

I find that Battery indicator doesnt draw much power if any as I've always used it and never had a problem. The maker of the app states it uses no extra power. I love the circular battery indicator version found in the market. Its not a widget, it stays in the upper left corner of your notification bar. You should give it a try.
Phone doesn't get hot. I've started from scratch twice, I've ##DATA# reset. I had terrible service and data speeds before I did that and it did a number on my battery. Now it'd fine, but it just drains while doing nothing.
I never use task killers or auto sync, I live with spare parts and and monitor it, no real partial wake usage to speak of. I know how to save battery, my hero get 20+ hours with use and auto-sync on.
I'm thinking my battery might be bad. Feels like your talking down to me too, captain.

I haven't had mine a week yet, but atm I'm not getting half the battery life I did outta my Hero running AOSP's Gingerbread alpha.
I'm blaming the crap bloat that's part of the stock ROM.
With the display set to 15-20% I've got the display accounting for 69% of the battery usage. :/
Turning off sync is not an option and I feel defeats the purpose of a smart phone. Additionally, I fail to see the point in paying for 4G and not using it. (I do turn it off if I'm out of area for it or don't expect to be using much data.)
So thus far I'm disappointed in the battery life... but still think it'll improve vastly once rooted and cleaned up.
EDIT: Just did a test running Angry Birds for about 10 minutes... maybe 15. It ate up 9% of the battery in that time. Added another 1% to the display usage.

I'm just trying to give advice so that other people understand what to do to get the most out of the battery. This wasnt meant to be just directed to you. Sorry for trying to help you out, Captain.

Miren's latest update last week is supposed to have "reduced battery usage". I've had no problems. Maybe time to come back to the Light..?
I was able to hit the 48 hour mark with light use.

hey that's really impressive. I thought my 20 hours battery life was pretty good...kudos to you.
def getting better bat supply. especially from my hero which only lasted about 6-8 hours, just got my shift yesterday afternoon. from a full charge: Constant texting, facebook, Zenonia 2 (Downloaded wifi), Snes emu + 11 roms (3G), and customizing it to my hearts content. almost 12 hrs later had 20% until i plugged it up at work.
so far this thing is a golden brick to me
Just out of curiosity, how do you calibrate the battery? Just in case my battery life doesn't match the reports (I know my luck )

Its under # 13 on my 3rd post.
getting great battery life isn't that surprising given you've got a 1500mah battery much like the evo and epic however 48 hours is rather impressive.
Sent from my cm7 Evo 4G!
Working on calibrating my wifes battery and damn this thing is hard to kill. Even with with everything running for 5 hours its still over 20% finally decided to bring out the big guns. Turned on navigation and the flashlight. I'll post when I see the battery life after calibration.

Edit: Phone plugged in at 7:53pm PST. Now to see how long it takes to charge.
Edit #2: Phone finally fully charged almost an hour after my evo finished its 0 to 100 at 12:19am
Edit #3: Holy F***. This phone takes forever to die and to die. Finally on the second off charge. I wouldn't still be doing this but for the fact that its saturday.
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...

Wait nevermind my previous post. I just read that you have frankenstein rom. so idk maybe your battery? Try. Different rom and see the partial wake usage in spare parts?

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.
