Greetings all, I was wondering if anyone else has noticed that their battery doesn't charge to full when using the wall charger or USB? I have LiPo chargers from RC cars and I have used one to discharge and fully charge the battery to 1400mah and found that the phone seems to have much better battery life than when charged with wall charger / USB.
When charged with the external ("direct") battery charger, I can get to 4211mv whereas normally with the wall/usb it only goes to 4173mv max. From what I know of LiPo/LiIon batteries, they need to get to their max charge voltage (~4200mv) or so and stay there for some time to get full charge.
I have noticed that my phone has terrible battery life when compared to my Touch HD which used to get 20hrs+ of full use on 3G/HSDPA, same usage pattern with push e-mail and I can't even get 12hrs with the Nexus One before the battery runs right down. And I thought the Touch HD had bad battery life!
Any help / feedback would be most appreciated. Thanks!
It's interesting I see this as today has been a very odd battery day. I woke up and unplugged it at exactly 5am. For 7 minutes I checked e-mails and twitter and it had dropped 3%!!! By 8am I was down to 82% (ride in to work, listening to music for 25 mins, thats about all) I was thinking this was getting silly. It's now 5pm here and I'm still at 61%?!?! So, over the first 3 hours it went 6%ph, since then it's done 2.3%... that's the best I've ever got from it.
Could this be related? It's not really fully charged, even though it shows 100%, drops very quickly and then when it returns to where it perhaps should be (around 80%) it acts as normal?
What is a LiPo charger and how can I use one to charge my Nexus battery?

iMAX B6 is what I have been using. I have another heavier duty one but this one is good enough for the battery. I have a generic battery charger thing which I got from China which holds the battery while the other unit charges it. Right now as I write this, my phone has been on for 1hr 25minutes after being charged with the charger, I have used the browser for 10minutes, on 3G, downloading things etc. and it is still on 4211mv and 100% charge.
Curious if this is an issue with the onboard battery microchip, or the radio/firmware. Does anyone know where to source an original replacement battery (non-generic replacement)?
The batteries in these smart phones makes no sense. The other day, I charged the phone overnight using USB, and the next day, I was at 97% after 3.5 hrs. Then, another day, with basically the same usage, I'm down to 85% after 3.5 hrs. No rhyme or reason. I wish someone could explain it.
I also wish someone could make a battery that lasts for 48 hours on normal use
"Drops very quicky"
same here but ive had this 'problems' since stock firmware. its not CM related.
I also noticed that its dropping from 100 to 80ish very fast when starting many apps in the morning for example. Like stopping airplane mode, starting some apps and opening browser. stays at 80ish for some hours then

Yep. That was the same thing with my Pre. It would never stay at 100% for more than a few minutes, and then it would plummet into the 80's, and then it would be okay.

I purposely left the phone not to charge last night from about 1AM - and I woke up (around 9:30AM) with it at 99% charge still. Used it for a bit and it dropped to 89% and now it's 1:06PM and it dropped to 75% with calls, web browsing and some other stuff. Previous days to this it would be at 75% after just 2-3 hours!
I also noticed that the phone didn't download any e-mails overnight (since there's no "scheduling" for peak/offpeak like in WM I assumed this shouldn't happen?) which may account for the minimal discharge.
All in all very strange, seems like I am not the only one with these problems - maybe I'll try get another battery and see what happens!
The thing about the battery in a smart phone is that it has a micro chip in it, and the phone reads info from it to give us the battery meter(this is true of any phone, actually)... your LiPo charger reads charge in a similar manner, only it doesn't talk with the batteries chip, instead it does it's own thing(I will spare the details)
With this in mind, what you want to do to get the most out of your battery is get the chip in the battery, and in turn the "circuit" it completes with the phone properly calibrated. To do this, you want to run the phone's battery down until it turns itself off. Do a battery pull and let it sit for a little bit (at least 30 seconds, I usually wait several minutes)... then, put the battery back in, and turn the phone on. One of two things will happen, it will either power off before fully booting, or if it does not you will want to use the phone until it powers off again.
At this point, pull the battery again and let it sit out of the phone for a bit again. Then put it back in, and without trying to power the phone on, put it on the charger and leave it on the charger until it is fully charged "green light comes on" plus a couple hours.(best to leave it on the charger overnight) At this point, take it off the charger, and then turn the phone.
This will properly set the low point and the high point for the battery stats. Do not do this a lot, it is bad for a LiIon battery to be "deep cycled", which this comes really close to doing. Ultimately, the phone is not going to charge the battery as high as a LiPo charger will, nor will it discharge it as low, because unlike an RC car's batteries that are used for rapid discharge, these batteries are designed and used in a slow long term discharge.
Thanks, I'll try that myself
Do you run any risk of damaging the battery when charging with a LiPo?
How to Make Your Cell Phone Battery Last Longer when you need it the most
Tips: How to Make Your Cell Phone Battery Last Longer when you need it the most:
1. Always try to drain your battery or wait till its 15% or below then charge your phone. Its very important to turn the phone off before you plug it to charge. This help maximizing your battery charge.
2. Stop searching for a signal. When you are in an area with poor or no signal, your phone will constantly look for a better connection, and will use up all your power doing so.
3. Switch off the vibrate function on your phone, and use just the ring tone instead.
4. Turn off your phone's back light.
5. Avoid using unnecessary features. If you know it will be a while before your phone’s next charge, don’t use the camera or connect to the Internet. Flash photography can drain your battery especially quickly.
6. Keep calls short. This is obvious, but how many times have you heard someone on their mobile phone say, "I think my battery’s dying," and then continue their conversation for several minutes? Sometimes, the dying battery is just an excuse to get off the phone (and a good one, at that), but if you really need to conserve the battery, limit your talk time.
7. Turn off Bluetooth. It will drain your battery very quickly.
8. Same goes for WIFI, GPS, and infrared capabilities, if your phone has these features built in. Keep them off; save more power.
9. Use GSM - Using your phone in 3G / Dual Mode will drain the battery quicker than if you just use GSM mode - have a look at your phones spec and you'll see it will quote two different battery life times - normally 50% more for pure GSM use.
Very Important:
Anyone purchase a new phone. Its best DO NOT USE the phone with the little remaining power the battery has. It is best that you put the battery in the phone and turn off the phone and change for minimum of 5-6 hours.
The 1st charge for the battery is very important for lithium ion battery. Leaving the phone off will give the full maximize charge the battery can take. Normal when phone shows charge complete by integrator light or on the screen means its 95% complete. To complete the 100% charge you need additional 1-2 hours after the full charge integrator show. Having the phone off also help keep the charge. A phone that is on and charging will never get that 100% charge because there is alway a little battery being drained just because the phone is one even if its plugged in to a charger.
If you see your battery is not giving the same performance what it use to. You can try this method at least 3-4 times for 1 week and follow up every other month. Meaning turn the phone off and charge it every night. It is best if you can drain the battery to 15% or less before charging the phone.

10. Keep the phone off, it'll not drain the battery at all!
So one person says don't let it drop down low very often, the next person says let it drop to 15% all the time...
Personally I've heard not to let it drop low more often these days. The old 'let it decharge regularly' was talked about a lot 4 or 5 years ago... no?

I think you didn't understand a LI-ION battery!!!
1. completely false
2. I've a mobilephone also I wan't to use it!!!
3. Maybe... Have you tested it with a ampere meter?
4. A black display is always a good idea!
5. Why not buying a Nokia 3210 ?
6. Better: Don't use it for call.
7. Correct! (If you don't use a headset)
8. See Pt. 5
9. See Pt. 5
A few facts:
- a new lithium-ion pack does not need cycling through charging and discharging
- Limit the time at which the battery stays at 4.20/cell. Prolonged high voltage promotes corrosion, especially at elevated temperatures.
- 3.92V/cell is the best upper voltage threshold for cobalt-based lithium-ion
- The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

I second this as well. The tips given by nuc70st is only applicable in the old days with nickel based batteries (Ni-cd and Ni-MH), which for the past 5 years mobile phones have in general stopped using and have shifted to lithium varieties. Nickel Cadium and a smaller extent Nickel Metal Hydride suffer from "memory effect" so it was important to deep cycle the batteries to maintain its capacity.
Lithium batteries in contrast should be treated in the opposite. You should keep it charged up whenever possible, and fast discharging (draining its charge as fast as possible) actually does more harm than good. Most mobile phones don't discharge it fast enough for it to be problem, but plugging a lithium battery in a purpose made discharger is still a no-no.
I dont know if anybody else can try this with their N1 but I have recently noticed that when my battery does its initial.. drop to 95% before you can wonder what happened, I can charge it with the phone on and the green light stays on, implying that the phone is fully charged.
Then I turn the phone off and charge it, and the red light quickly comes on and allows another hour? of charging before the green light will re-appear.
I think i'll be trying leaving my phone on and on charge overnight and then turning it off while I get ready in the morning and don't necessarily need it.

I'm right and the other guy is dead wrong. Deep cycling was better for nickel metal hydride batteries, because it helped delay the memory effect.
No such issue for Li-ion batteries, plus charging makes Li-ion batteries HOT, which isn't particularly good for the battery. So numerous charges leads to less exposure to prolonged heating.

Since applying the 1.47... OTA, I can literally watch the battery drop minute by minute while the phoe is active.
Within the first 1 minute of removing the phone from the charger the Battery Status Pro reports the charge droping from 100% to 97%. That's a 3% drop in 60 seconds.
Within the first 3 minutes of active use BSP reports the battery drops to 93% charge. That's 7% loss in less than 200 seconds of use.
Now I'm not saying BSP is 100% accuerate but I expect it's not too far off.
Battery life with the Evo has never been phenominal but this seems rather extreem. The drop seems far faster now than when running the 1.32 release. And... while I am in a 4G enabled market, this is with 4G disabled and the phone running purely on 3G with no flickr, twiter, facebook or other feed widgets running and autosync disabled for all of them.
When I look at Battery Use under settings / About Phone / Battery the Android System is by far the largest user of battery, nearly twice the next closest user which is Cell standby.
Am I the only person experiencing this?
The phone was doing this before the 1.47 OTA, it's a problem with charging the battery in the phone. It does not charge properly for some reason and it will drop all the way down into the 80's within an hour of unplugging it. If you get an external battery charger and use it to charge the battery the phone will stay on 100% for an hour or more...
Have you removed the HTC people widget from home screen? The day I removed that was the beginning of decent battery life. Also try turning off the phone when charging - seems to work better that way.
I would try charging to 100%, unplug, wipe the battery, plug it back in again until the light turns green and try again and report back.

I wondered if it was the powered off portion of that battery trick that was doing it. Hmmm. I'll have to watch. Is there any link/source on the idea that the phone itself is not working so well at charging?
Out of that voodoo on the getting better battery life the only thing I could come up with was...-charges better when off, - you need to charge for a bit while on to reset the battery indicator, - and charge a bit while off to top it up.
So I was leaning toward it being a charging thing and not a battery thing...would like to see any technicals though and not just my guessing.
People widget has been long gone.
I gave the charge it with the phone powered off thing a try. The device was down around 80% charged when I powered it off and plugged it in. In about 5 minutes the charge indicator turned from amber to green as if it were fully charged.
I can't believe that the battery charged 20% in 5 minutes.
This leads me to believe that the first response is correct. The battery simply isn't charging fully in the phone. I believe I'll look for an external battery charger and give it a try. See if it makes a difference.

Seriously, try full-charge, wiping your battery data and then shutting it off and 'topping it off' and reevaluate the situation.
EDIT: The "topping it off" thing is all voo-doo as far as I'm concerned. I just do it to be safe, though I'm pretty sure it's ineffective.
I screw with my phone so much, so much flashing/restoring back and forth while on charge, between
charge, car charger, USB charge at work, wall charge, flashing again, kernel swap, restore back again...etc etc etc...that if I don't wipe my battery once I hit a full charge there is no way I can trust that meter to do anything more than change colors. I do it every few days when I notice the meter isn't being trustworthy.
If this doesn't work for you I'd say you probably have a bunk cell in your battery, and failing that your phone just might not be charging well.
Also, charge with the wall and not USB. USB takes forever. And 20% in 5 minutes isn't TOO far off if you are plugged into the wall and getting full-power charge. Maybe 10-12ish minutes, unless you were timing it very specifically....
I just got my bricked replacement. Here is the data from a 100% charged battery usage up time 18:13 .. Awake time 15:27 the battery is at 87%

with heavy usage
I have allready read:
Battery recalibration (Thanks to Cyanogen for this and to fachadick for bringing it to my attention).
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2. Boot to recovery and wipe battery stats.
(To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for your ROM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue.)
3. Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off. Take out the battery, and keep trying to turn on your phone until it will not turn back on at all.
4. Recharge the phone completely and then use as you normally would.
This is a method that has been proven to work, I am sure there are other ways. My battery lasts longer after doing this and the reading is much more accurate. It might be advisable to do this after every ROM install if you want the most battery life and most accurate battery reading by the phone's software.

My question is dose the phone need to be off or on for stage 4 the recharging of the battery?
If it can be off for stage 4. Dose it need to be charged in one sitting or can I charge it partially then take it to work and then charge it the rest of the way before I turn the phone back on?
This my second attempt at doing a battery stats wipe. The first time I tried I left the phone on wile charging and the battery only charged to 3800mV calming it was at 100%. I had to bump charge it 3 times over 3 hours before the battery was up to 4100mV-4200mV and clmaing 100% charge capacity.

I wonder if this means that I will not be able to have proper battery stats as my phone likes to stop charging and claim that it's at 100% when its actually at 50-80%/ (It dose this 95% of the time... It even did it with the stock battery stock battery a couple of times)
Hi to all i am facing massive drains in battery
My phone recharges in 1.5 hours completely.
But i dont think that this is reliable as if i use my ideos with automatic brightness and on demand 400-1000 franco kernel.i can play game for continously 1.5 hours maximum.
And on wifi its about 4 hours.
I think its battery calibration issue.
If any expert here make a guide to properly calibrate our batteries than we can get most out of them.
So experts please come one step ahead.
Sent from my HTC Pyramid using xda premium
To calibrate the battery you have to charge the battery to 100% and leave charging after 100% for about 30 minutes. After the 30 min, reboot into CWM, go into advanced and select Wipe Battery Stats. Reboot the phone again.
You won't notice much of change initially, because you have to repeat this process at least 3-4 times. In about a week time, you'll see that battery will last twice as longer.
This may not work for everybody, but it DEFINITELY worked for me.
Just download this app, plug your phone to charger, when that app shows over 4200mV press "Battery Calibration" button and then use your battery to 0% and then charge it back to 100%.

Gonna try this. The first time I did it I didn't notice much but today my battery has surprised me greatly.

NO juice defender app! That's making things worse, in my opinion.
Yesterday, my battery was running perfectly fine. Today, the battery goes for about 10 minutes on screen time. Getting it charged from 10% to 100% is very quick, maybe takes about 10 minutes. But going from 100%, it can discharge at about 5% per minute, regardless if im using it or not. When I was at 70%, i tried to restart my phone to see if it would fix it, but when It was going to turn back on, i was greeted with the low battery sign, signaling that the phone wasn't able to turn on. 70% = No Battery? Battery drains by 2% per minute when screen is off.

Your phone needs to re calibrate the battery. This is probably the bit I like the least about these phones. Near as I can tell the best method is to let it drain till dead - then plug in with your charger and leave for several hours. Power on while phone is still plugged in - let it continue charging another hour.
Use normally. You may need to repeat this a few times.

Your phone needs to re calibrate the battery. This is probably the bit I like the least about these phones.

I've done that about 4 times. It didn't really make a difference... then I used a battery callibration app from the play store which didn't even require a full battery drain or charge and it worked very well... weird.
