How long does the first charge take? - Nexus One General

This is torture, I'm waiting for the light to turn green, how long did it take? I've been waiting over an hour.
This is the best cell phone in the world, I wanna play....

you can use your phone while it is charging...
the light turns green at 90%, but just charge it until the android battery does not show the lightning bolt on it anymore (first charge it will show it even after 100%).

Ahh, the user guide isn't clear on that, so as long as I leave it plugged in, the Lithium Ion won't go nuts?

If I turn it on that is.

Li-ion batteries actually dont have a memory, so you dont have to give it a full charge before using it. Its not a ni-cad.

HD2 battery never charges to 100% in Android

Hello, I'm using Mdeejay Froyo Sense 2.4 with hastarin 7.1 kernel.
I noticed that when I'm charging the battery in Android it never goes to 100%. It reaches 96-97%, voltage goes to 4.197V and the led stays red. If, after that, I restart the phone, both in WinMo and in Android, the indicator shows 100% and the led is green.
I'm worried if the battery charging is performed correctly in Android.
I would be glad to read your opinions on that.
Thanks!

In the hyperdroid thread there is a command to "calibrate" your battery or something.
Turn your phone completely off. Charge to full - green led instead of amber. Boot back up and restart android. You should be good to go.

Both of these are good advices; and remember when switching from build to build, you'll probably have to do this a few times.
u most likely have an extended battery ... it configures itself to your other battery , thats why its telling you that ... btw , it does charge too full battery (4.197v) only the % value is wrong
oi. hasnt this been answered 1111111 times by now? ..please people use the search feature, its not just a pretty button.
Thanks!
Thanks to all of you for the advices!

To malaeus: I used the pretty search button, but I didn't find anything similar, maybe because I didn't include the word 'calibrate' (I didn't know that I'll have to "calibrate" the battery). And if you had read my whole post, you probably would had noticed that this is only the first part of it. I also wrote that: "I'm worried if the battery charging is performed correctly in Android. I would be glad to read your opinions on that."
So, with no offence, I think you overreacted a little bit.
Thanks!
The full charge battery voltage is not 4.197 it is 4.202
LI-ION charges to 4.2 volts, this is 70% of full charge, after this a "Topping Charge" is applied, this can take longer than the original charge to 70%
once the battery stops absorbing charge current this is when the battery is 100%
I would suggest using "Current Widget" to observe this, android will often state a 100% charge when the battery reaches 4.202 volts, but current widget continues to show a charge current, wait until its below 50mah or so then unplug the charger, delete the batterystats.bin and reboot the phone, that should calibrate android perfectly.
If you can live with your phone turned off for a while, delete the batterystats.bin and shutdown, then charge with the phone off. this will perform a total and complete charge with full topping charge.
Just one bit of advice... do not leave your phone on the charger all night every single night after getting a perfect calibration like this, having a LI-ION battery sitting on 4.2 volts for like 7 to 8 hours a day will simply kill the battery in under a year if not within 8 months.

Very informative! Thank you very much!
Is my battery or adapter getting broken? I did both types of calibration and I never saw a value bigger than 4.197V. Even when I fully charged the phone while off and booted to Android the indicator was at 4.154V.
Otherwise, when fully charged, the battery lasts in Android almost as much as in WinMo - 40-48 hours.

Thanks for the info! I never charge my battery in Android, but I noticed, that percentage indicator readings is different between Android and WM.
One more thing, I searched for "calibrate" in HyperDorid thread, and here is what I found "charge full in windows then remove battery and charge full in android to calibrate..."
I do not get it. How can I boot Android without battery, and how can I charge already charged battery?
I copied this from another thread here, it has worked for me well.
Fully Charge while Device is Off before first boot, then upon first boot go to terminal and enter these (without the quotes) and press enter after every line.
"su"
"rm /data/system/batterystats.bin"
Ensure that Keypad Lights are on when Haret is launched and you will be healed.

[ISSUE:LAG] Homes Screen Lag

I noticed that after unplugging my phone when it said it was fully charged the battery immediatley dropped to 97%. I found a thread in the Vibrant forum with people talking about their Vibrants doing the exact same thing. No one seemed to know what was causing it. Is anyone else seeing this with their phone? Should I be concerned?
it's normal on a Samsung phone. There is no fix. Sorry for the bad news.

Thanks for the reply. It doesn't bother me as long as it's normal, just wanted to make sure nothing was wrong.

Yep. From my experience I've discovered the following:
1. Keep it on charger for a extra 1 or 2 hour.
2. Charge it while off.
And you won't see that drop again. If you do one of those things.
It's normal on every mobile phone.
Here's an explanation.

It is normal, it was designed to do that to prevent your battery from burning out sooner thus giving you shorter battery life in the long run.
If you want to truly charge to 100 percent, you bump it. Meaning when it says fully charged(its lying to you), pull out the usb charger, then plug it back in. When it says 100 percent again, pull out the charger, put it right back in, let it charge a few mins more. Keep doing this till you get bored. Doing this bumping technique will truly charge it to 100 percent, and it won't fall so quickly, but it burns your battery supposedly in the long run.
There was an article about it. Google bump charging battery, or something like that.

Yup -- once the battery reaches full capacity the charger stops (to avoid undue wear on the battery). The battery will discharge down to ~90% before the charger kicks in again.
On Nexus One we were able to run off of wall power once the battery was charged, significantly reducing the speed at which the battery discharged once full, and improving the chances of it being 99-100% when you took it off the charger. Nexus S has a different charge circuit configuration which does not allow it to operate in this mode.

battery wont charge to 100%
I was wondering if anyone else was having a problem charging their Nexus S to 100%. I have recalibrated it by draining it then charging it while its off for about 8 hours.
Ever since I first got it would only go to 97%. I also tried to delete the batterystats.bin file and that's not working either.
If I bring it back to Best Buy should I relock the bootloader and get a new one or will they replace just the battery for me?
Thanks
I'm having this issue as well and am wondering whether or not this a prevalent or not.

Charging battery to 100%

If you leave ur wirless tethering on while charging, your battery will charge up to 100% and stay 100 even if you take off the charger.
I hope nobody posted this method already
Nice! Ill test that later today

Charging to 100% will not shorten the battery life if any Lithium Ion or lipo battery, but if you discharge past 5% will kill the battery faster. This I know from using the lipo battery's on my big RC Helicopters and that the ESC's have a low voltage cutoff on them to keep from doing damage to the battery. All lipo batterys are built the same so before someone says it is not the same, YES it is!!!

Already posted, and already shown that it doesn't work...battery still only charges to 96-97%
And there is an issue with the firmware in the Nexus S that prevents it from fully charging to 100% (incorrect voltage cutoff level?). This is NOT a deliberate way to "save" battery life.
Charging to 100% does NOT harm the battery or shorten its life in any way. Li-Ion batteries work best and have a longer total battery life when topped up to 100% regularly.

i believe i heard 2.3.5 will fix this and many other issues we are having.
Another way to fully charge your Nexus S is by switching it off and plug-in it to a wall charger until it finish charging (you will notice that by means of the white battery icon that will show up if you press -just a single touch, do not keep pressing- the power button). Every time I charge my Nexus S this way I get a full 100% battery charge.

ive done this and i never reach 100%. the highest i have gone is 98%.
This is curious. I usually pick my phone in the morning and read some tweets and news before I get up, while the phone is still connected to the charger. When I 1st take it it has about 96-97% but after I use the phone for some time it goes up to 98 or 99%, but never got 100%.
does that 5% really make that much of a difference? maybe it helps the battery to not go to 100%, maybe it doesn't...
but are you really using the battery down to 5% before charging it where it makes that huge of a difference?

guys is better to charge the phone before it is <5% or not?
if you leave the screen on while charging, you can charge it to 100%, i do it a few times a week. as soon as the screen goes off over 95%, it will stop charging, at that point just unplug it, then plug it back in and leave the screen on. itll get to 100%. have patience, itll just takes some time.

If you want to wipe the battery stats so you can make sure you are getting 100% out of your battery use the phone till it dies all the way and it turns off. Then turn it on and use it to till it dies, and repeat that process till it will not turn on at all. Plug it into a charger and turn it on & boot into bootloader > select recovery > advanced > wipe battery stats > reboot system and let it charge for at least 8 hours with minimal use.
@kim, charging the phone for that long will not have any ill effect on these batteries. They use LiPo batteries which are extremely different from previous phone battery designs. Our phones actually have a programed system that will cut the charging back and turn it off as the phone battery reaches the max. Once it reaches the max the phone will not charge the battery. When you battery gets HOT from charging is when to be worried. Heat and overcharging (which is next to impossible) are the two biggest killers of LiPo batteries.

I only know this because i use LiPo, NiMH, and NiCad batteries in my Electric RC cars. Been into that hobby for going on 20+years.
Takes about 2.5 hours for my phone to charge fully from 0%
The battery ages, and the time it takes to charge it goes up. Perfectly normal.
if you take the battery out and shake it for about a minute it will charge faster.
Are you kidding? haha
yes lol was wondering how long it would take for someone to speak up.
I think it is actually healthier to charge the battery slowly. Fast charging heats the battery... 2-3 hours seems reasonable.
And of course, shaking does not help- without the ice

Battery readings are totally off!

Hi guys, I've got this phone passed down by my mum. It's an old Samsung Note 4 but it's still working fine except the battery readings are totally out.
When I mean totally out, it's like switching off when it hits 30%. Sometimes it keeps going on after it hits 0%. I tried keeping a battery pack on it but it'll just do the same thing.
Just like to know if it helps getting a new battery or is there anything I can do to 'reset' the battery?
Thanks folks!
When a Note 4 shuts off at 30% that usually means that the battery is toast. Get yourself a new Anker battery for $16.99.

Like previous stated, battery is most likely going bad. But I figured I give you an alternative to try first. It won't hurt.
Power off your phone and charge it to 100%
Turn it on.
In play store search for "Nema battery". The first result should be it. It's called "Battery Calibrater" and is by Nema.
Install it. And follow directions.
Most all battery apps are crap. But a few people told me this really does calibrate the phone.
Also take note of what amps capacity it says your battery has.
It maybe worth the try.
Thanks buddy, I'll give it a shot.

That's the voltage. When it's plugged in, it'll be close to 5v. Unplugged it'll be lower.
That app might not have the reading I'm thinking of. No matter, you can try it.
Just for comparative proposes, I just installed it. And yes mine also shows 4300mv max.
But unplugged it's showing 3995mv, I'm at 75%.

I see.
I think a different figure shows up when I charge it turned on or off. If I hit 100% charge, it'll show up with less than that when I try charging it turned off.
I'll try the app once I get to 100%. Is that 100% referring to the phone being turned on or off while charging?

They mean with it on.
I only suggested charging it off. Cause it's suppose to charge fully better that way I guess. You'll be able to tell when it's fully charged that way. Either way probably won't matter for your case. Cause it's either gonna help or nothing much, then you'll know if you should move on and try new battery.

Yeah, you're right, last ditch effort to see if the battery works.
Another strange behavior is the speed of charging. I use the same charger with the same cable for this test. Funny thing is sometimes the battery takes ages to get to 50% from 0% but on good days, it gets from 0% to 50% in a snap.
Is this behavior of a faulty battery? Or am I dealing with a faulty circuit board? I'm on stock ROM so it's easier to troubleshoot.

I couldn't say. But it sounds like fast charge is working on and off. Probably bad aging battery.

When a Note 4 shuts off at 30% that usually means that the battery is toast. Get yourself a new Anker battery for $16.99.
