My batter seems to go from 100% to 85% every day in a very quick manner. However, after that, it slows down. Maybe it is just the behavior of this battery (or the software that measures it).
Regardless, even with that, I get 12-14 hours (with moderate usage) before I get the 15% warning.

I noticed that as well, ill keep a close eye on it again today, i do have very heavy use
spare parts is helpful as well
If you're running a 2.1 ROM:
Don't forget to change the Network Mode to "CDMA Auto (PRL)". Do this by dialing "*#*#4636#*#*", and then pressing Phone Information. Even if it is already set to CDMA Auto (PRL), press it anyway.
Try using a 2.1 with a tweaked memkiller. It'll help to kill off apps that are still running and using battery. I usually get about 2 days of battery out of my phone while using TrevE's MOD.
I think the battery discharge curve that dictates battery level is off in the 85-100% range on these phones.

if you charge over night first thing in the morning do something to get it down to 99% then plug in charger again, i find my phone will charge for a good 15-20 minutes and the battery drops much slower

i had the same issue. download spare parts (as was mentioned earlier) and check 'partial wake usage'. sprint's voicemail was keeping my phone awake for some reason. i ditched it and have great battery life now. google voice all the way...
What is this TrevE Mod?
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
Have you guys noticed any issue with the charging speed of this phone?
Last night when I went to sleep, 8PM (i know early), the battery was at 9 or 10 percent. I plugged it into the charger and all that. So this morning I go to remove the charger to check e-mail and what have you. 94%.... Come on, its 4:30 AM so that is eight and a half hours and not 100%?
Is this in the experience of anyone else? (Also do not let stock battery meter fool you, it doesn't show accurate measurement of the battery.) If not, what are you guys doing? Or is there anything I can do?
Honestly, 8 hours to charge your phone does not seem right. Something is wrong with your battery. The vibrant does take a long time to fully charge, but never 8+ hours. It usually takes mine a good 3-4 hours when my battery is dead.
I highly recommend download the application juice defender. Research and learn how to use it. It will save you tons of battery.
I'm currently on my 38th hour since the last time I unplugged my phone and I still have 8% battery. Btw, I've been using my phone for phone calls, texting, and playing games.
First of all thanks for the JuiceDefender tip, that looks very promising.
But do you turn your phone off at night to charge? Because I just turned my phone off like 20-25 minutes ago and it popped it all the way to 100% just as I was typing this response.
Any other suggestions, tips, or concerns from anyone, please share.

No, I leave my phone on. Usually with Wifi too.
Also, I have a simple wallpaper that is mainly black (it has some blue designs, but the wallpaper is mostly black). Having a black wallpaper saves battery as well because the color black consumes the least of amount of energy from our screens.
Well my homescreen is pretty black. Black mesh background, black icons (bettercut). Black bar mod. Just got done configuring juicedefender, even bought the pro version. Figure if it doesn't work out I can simply return within 24h. And, I will know within 24 if it is helping the draining.
Leaving Wifi/Bluetooth/etc on will suck your battery down. Turn it on only when you need it. This is true of all smart phones.
My Vibrant will charge to full in a couple of hours from dead. I get 10+ hours on a charge even with heavy use but I almost never use Wifi or BT so YMMV. I definitely get better battery life from the Vibrant than the old G1.
Curious if you could pay attention some time when your awake... my phone rarely charges past 98%. Wondering if your phone is charging up to 94% quickly, and then hovering or if it's actually taking 8 hours to get to that point?
Maybe you should get a replacement.
I can plug my phone in around 10pm and at 6am my battery sometimes says 98-99%, but normally is good to go shortly afterwards. I do turn my phone off at night and those that need me do have my home number too unless I'm traveling.
As well I normal usage is 6am-10pm or so and I have typically 40-60% left on the battery depending on the usage. Yes I do check the About Phone and not relying on the wacked out battery meter.
I don't leave wifi, gps or 3g on all the time simply because I don't need them. Id rather squeeze the battery than have something on that isn't being used anyways. Having that quick settings drop down in the Notification bar rocks.
I have the same issue. It always takes about 4.5 -6 hours to 'fully' charge my Vibrant from <10% regardless of whether the phone is on or off. Then after unplugging the charger, the battery info states that the battery is charged to 96%. My belief is that there are firmware issues with at least some TMO Vibrant phones. I'm also dubious of the USB charger. I've ordered a regular charger and I'll see if my suspicion surrounding the USB charging system is founded. Maybe...

Mine takes about 3 hours to charge but I normally get about 13 hours a day on it with normal to serious use. I haven't had a problem with battery life since I purchased it but I have been trying new battery saving techniques to see how long I could make it last.
Currently using a mostly black background. Wifi only when I'm in the house. Brightness all the way up. Synching two email accounts and Facebook all day. Definitely getting the most out of the battery that I could expect.

Well mine takes a while but not that long. I'm going to try out the juiceDefender that was mentioned but the other thing I would recommend is the accurate battery mods that can be found in the Themes and apps section. You can flash with clock work and it's a great way to know what your battery is actually at so you can see how much you're using for various things.
Make sure your charger or USB port has high current output. There are some out there with only a few hundred milliamps. The phone will take nearly one amp and should charge in a few hours.
Excellent point. For me, I'm using the supplied Samsung USB to 110v adapter and I'm getting 4.5-6 hour charge times.

Also the USB cable is important too. 1 amp over a long, skinny 5 volt cable can drop the voltage. If the charging chip sees a lower voltage, it will think the USB port is at capacity.
I love this phone but I must be honest.. this phone is worst as the Motorola cliq battery wise. it's terrible. I had 100 percent battery life at 8am and at 10:50am I had 23 percent battery left............ no matter what I was doing.. even if I had the screen on full blast *i had it on the lowest* it still shouldn't be almost dead in 3 hours .... smh!

One poorly written application running in the background could be causing the CPU to wake up constantly. Yet I can talk for hours and the battery will still be nearly full.
I know for sure one of the latest versions of Facebook ate batteries like crazy. I ended up installing an older version and my battery life returned.
Update on the issue. I was using juice defender but it wasn't doing anything for me as far as I could tell. I have since turned off vibrate on touch, and noises coming on during clicking. I am using a usb hub with two vibrants on it. I'll plug it into the wall tonight and see how that goes.
I have been turning off my wifi when not using it. A little better I suppose. While typing this I went from 49 to 46 percent and I am a fast typer. No wifi bluetooth gps.

Yes the battery drains pretty fast, and it does take about 3 hours to charge... my main problem is... at night when I plug in to charge, couple hours later I get woken up by a beep and popup window telling me charging is done and to unplug...
anyone know how to turn that off?
My dad's Droid 2's battery life just took a nose dive about a week ago. He is running the rooted stock 2.2 rom, few widgets on the home screen, no task killing, and he hasn't gotten any apps in the last month (I don't think he knows how). Did his battery just die (unusable, not no capactity) or is there anything I can try?
What I would do, is tell him to get the battery to where the phone wont turn on anymore, its COMPLETELY DEAD. Plug it into the wall until its 100 percent, then drain it down to about 10 percent, then plug it into the wall again. After another complete charge, it should be good again. Its called reconditioning the battery. I do it about once a month.

I've heard a lot that Lithium-Ion batteries shouldn't be conditioned too often, because they only have so many charge cycles. I'm not expert though. (Don't let this keep you from trying what boogerburns suggested. I could work for you. I'm just stating that Lith-Ion batteries don't like to be drained a lot)
Anyways, the battery could have gotten a bad cell. You can check the battery condition by opening the dialer, and hitting *#*#4636#*#*
This will bring up a menu, and you can choose battery info (or something along those lines) If battery condition is anything but "good" then he'll probably need a bad battery.

I did check on the battery condition somewhere, and it was "good". However, I was wondering if there's a way to check uptime/awake time on the D2. My Inc had bad battery once, and I knew it was a lemon since the uptime was far more than awake time. I'm afraid that a rogue update is sucking my dad's battery.
How can I check my uptime and awake time?

Use the code I posted earlier, and this time select battery history. Select "partial wake" and see if anything is keeping your phone awake. Also look at network usage and see if anything is using that too much.
Alternately, you can download an app called Spareparts from the market (free) and you can get this information more quickly.

This looks like a bug and that the battery was never fully charged. Your screen shot "shows" the battery drained 90% in less than 3 minutes. I'm pretty sure a lithium cell actually subjected to that would have caught fire and exploded. There's no bounce back in voltage either, as would be expected after such a large drain. There's something wrong with how your phone is reading the voltage of the battery.

I wouldn't worry unless it does this again. The Nexus 4, on rare occasion, has some weird software bugs when it comes to charging. Nothing permanent or really inconvenient in my experience. Just 1-time errors.
ok i will keep your advice and i hope to never does it again...
