2150 Charge Time

For all the owners of the 2150 battery
How long is it taking you to get the green light? Today I burned it down to 11%, put it on charge and it's been 3 hours so far. spare parts says its at 98%. Anyone's charging quicker/slower?

3 Hours is about right. Then if you turn OFF the phone the battery will take another 30-40 minutes to get the light to go back to green.
Thats what I am experiencing...

I would have to agree mine is taking quite a while to charge. Fine with me because it also takes quite a while to discharge!

Yeah, you'd need to do the math to determine difference - but if charging the 1300mAh battery takes 1.5 hours sometimes then the 2150 battery taking 3 hours makes sense to me because of how slowing down the charge once the battery approaches 80% is going to slow down the entire charge process.
I'm consistently seeing 3 hours to get back to full charge after I totally killed it...

[Q] How often to change batteries

My phone dies so quickly it's not even funny. ~20% in 1 hr even after just barely using it.
- Using Android (CoreDroid Nand)
- Bought it second hand, but I've had it for about 4 months.
Should I get a new OEM battery? or is this just normal?

That's not normal amigo.
Get CurrentWidget from the market and see how man mAh it's using, even when the screen's off. Can help diagnose the issue more clearly then.

Have done, and it's often hovering between 4-6 ma during screen off, otherwise, when just playing with animations, it stays below 300-350 ma.

yes you need a new battery. on android my battery lasts from 24-36 hours depending on how much I use the phone.

wrap it up so no moisture can get in then put it in deep freeze over night or 24h, take it out and then let it thaw at room temp and then charge to full.
In some cases this will work and has worked for me on a laptop battery and a phone I had a few years back. They used to die after a hour or so and then after freezing they was back to normal for a good while.
If it works or you get a new battery always make sure never to put it on charge unless its nearly dead, ie 1-5% or max of 10%. If you keep on putting batteries on charge when they are not dead this f*cks them up as some battery types have a sort of memory.

Yeh , i learnt that in my physics class too Make sure that there is no condensation when you put the battery back in the phone.. it could spoil the internals!

Those actually sound normal. What you should do is check how much juice the battery is retaining. Let it charge fully - charge until current widget is reporting single digit charge. Use spare parts to check the battery information. If it's significantly less than 4200mv at full charge then try to wipe the batterystats.bin from /data/system, reboot and charge again. If it's still very low voltage then you need a new battery.

NiCad had memory problems like this, but NiMh and LiIon are not supposed to have this issue.

I always wipe batterystats when flashing a new rom, and it's pretty much at 4.2 - 4.22 at full charge

My sd android builds will last 24-36 hours if I don't hardly use it and keep it on standby... that's with getting 4-6ma drain. If I use it, though, it will only last 4-6 hour of straight use, depending on what you're doing. That's with 150-350ma drain during use. So with normal use I can usually make it through a 12-18hr day before charging. I usually carry a spare battery with me just in case though.
Normally, Li-ion batteries life-span is around 300 charges before they start degrading and not holding a charge as well... so if the battery has been used a year, it's probably time for a new battery.

I think this is a great topic. My battery uses about ~350 mA on just browsing internet, and dies within several hours (about 3). At 100% charge it says 4202 mV in spare parts, but dropped to 99% and 4138 mV within next minute. In another nibute it dropped to 98% and 4108 mV. It means battery not holding charge well? Stats were wiped before flashing

Three hours of browsing is not bad - but three hours of continuous screen turned on is a sure battery killer. Have you set your screen to a dim setting, or is it bright?

My battery dies very quickly too, about 4 hours on Android, with heavy usage, and about 2 hours on WP7
I have the official extended battery, though, and also the Cheap Chinese one, so i have backup

Depends. I often keep it on auto. The place I work has very bright lights. I read a lot about HD2 Before I got it. Powerful phone with a tiny battery. On the stand by it actually isnt bad. Eats about less than 1% per hour. With little use, texts and calls, it can last quite a long time. I asume my battery is fine.
What is your mV reading at 100% and less than that?

Dunno. I don't generally check that kind of data. My phone is at 69% right now, mAh is 8694.
NRG ROM includes tBattery. This particular battery showed 12296 MaH at full power, but this is only the first discharge cycle for the battery.

Not true man. On NiMH rechargable batteries (those are really old - I've never actually seen them in phones although I'm sure they were used sometimes... I still see some AA batteries of that kind laying around though) have a memory effect and get screwed if you charge them without depleting the battery life first.
However, we have Li-Io batteries - which, although there's been a lot of controversy, it is basically agreed upon that either it doesn't matter when it's charged or it is actually better NOT to fully discharge (except for around once a month in order to calibrate the battery).
But the freezing the battery thing is pretty cool! I have to try that on a friend's laptop battery that got screwed up!

that is way beyond normal. change your build.

Have done (flash one every couple of days), and still the same problem, also tried what TheAthiest said, but didn't make a dent.

Would Task29 make a difference for this person? Just throwing that out there

standby battery drain?

Sooo. I have had my Optimus 2X for 2 days now. I charged the phone fullt before goint to bed and left wifi on. (should turn off when phone sleeps)
The first night i lost about 3% of the battery. Great....
But... The second night i lost 42%!!!
I have been trying to investigate the issue and after some digging with spare parts i found out the wifi was on all the time the second night... Also for some reason car home allways runs in the background (starts at boot and restarts if killed) and spare parts claims car home uses the phone sensors 100% of the time.
Anyone else having battery draining issues?
Im going to charge 100% again tonight and run with no installed user apps. If the problem persists i try and freez some of the loads of sys apps that run in the background all the time.

I also noticed some battery drain on mine but not over 40%... its more like 20%. The battery really disappoints me anyway. I have to recharge two or three times a day?l maybe thr battery needs to get trained over time, I hope...

My battery already holds up alot better now, then when i got the phone four days ago.
About 60-70% left after a 14 hour day with some surfing, benching and calling/texting. Much better then my Desire on stock ROM, but still nowhere near the Desire on custom ROM.
Looking forward to some community goodness
BTW, removing carhome.apk seems to make quite the difference.

Same here

Quick question about best used on the battery ...
Should we dry the battery to 0 for the first cycle ?
Or only to 20% ?
Is it bad if we start to charge the phone whent the battery is at 60% ?

On the contrary:
modern Li-Ion batteries don't like it if you discharge them to a minimum. Moreover they don't have the memory effect that you seem concerned about.
In a nutshell: Charge your phone whenever you can, at any charge level. Your battery will thank you.
On the first few charges though, you should always charge to 100% to help the battery gain her full efficiency

hey thx about those informations
but then i'm concerned about people saying stuff like "have been doing 3 life circle" for me it does mean they put the battery dry clean ...

Went to bed with 64% charge on the battery. When I woke up (8 hours later), still 64%.

What's your usage like?

Hmm... My phone last for 6 hours before drained... Had it for a week now... Takes about 2 hours to fully charge up again..
I even hardreset, turned of wifi etc... but alas, 6 hours and it was out of power again...
And that was just by being in standby.
If I actually use the phone, I can see the percentages going down from 100 - 0 in no time..

My battery is useless to. Yesterday ive charged my phone 3 times hehe.
On moday I'll send it to the service as DOA.

Gonna try getting a new battery tomorrow... Hopefully it isnt the phone that is faulty...

2:nd day in my phone lasted about 5.5 h before I hade to recharge. Turned off the option for applications to sync and 20 hours later im at 32%

[Q] How long does it take to charge your phone?

As topics says and like your battery is under %20 percent approximately how long does it take to get it fully charged

About 1.5 - 2 hours

Mine seems about the same, however if your using the phone wile charging it takes a lot longer, which is strange because there should be enough current to charge and use simultaneously.

1 hour 45 minutes from 25%, also I have juice plotter installed and theres a widget that you can put on your homescreen that changes from time left to how much time it takes to charge when it is actually charging which is kind of neat.

ty i think my phones charge time is increased will try tonight again

3:35 from 0 to 100

yep! for a moment was wondering if there was something abnormal with my phone.
/h2

You guys could try a 2 amps charger (such as the one that comes with the ipad), theres some evidence it will charge faster, although not by much.

30 seconds.
(battery swap )
But seriously, about 3 hours from empty to full on the charger that came with it, and about 2 hours with my 2amp galaxy tab charger.

True when I charge my GS2 with my Galaxy tab charger its dramatically faster.

._. there must be something wrong with my gnote then ... it takes around 4h30m to fully charge from around 10%... and even longer if using phone at same time...
I had several smartphones and this one is the one with the worst battery ever ... my dell streak's battery charges faster and even tho it also has a 5" screen, its 1500mAh battery lasts longer with the same usage.
Yesterday my gnote battery took 3h30m to go from 100% to 13% just from playing 2h30m of games and 1h browsing... innaceptable! and I do use betterbatterystats and I have few wakelocks that could be draining battery...
This phone charging scheme is really crappy, as I understand from my use, while charging instead of the charger powering both the phone and the battery at same time, I think it only charges the battery and the phone is always powered by the battery alone...
I din read about it yet, but I almost sure the gnote works like that, cause if i use Skype video call for example, i only get a 1% charge increase around every 10mins, which is really ridiculous ...
plus, while with my other smartphones I could take out the battery while charging it and the phones would keep powered, same thing doesn't happen with the note... battery off while charging, phone also off, which can only mean IMO that the phone is 100% only powered by the battery even when charging...
Besides making it take longer to charge, won't the battery life also decrease that way?..
.

How's my charging routine?

Is my charging routine bad? Here is my daily recharging
I let it charge over night. By the time I get home its normally in the 60% or so. So its left on all night until about 7am.
Then about half way through my day I charge it again while I'm at on my office. By then the phone is around 70%. So I let it charge to 100% then move on with my day.
So about 2 times a day I charge my phone. Is this healthy for the battery or does it not matter? I'm trying to get the most out of my battery. I seem to burn about 3-4% per hour with it just sitting on desk. Thanks for any advice!

Nothing wrong with that
You are charging twice a day though so you will half as many days until your battery dies. Still a couple of years until it reaches 80% capacity though

Well yeah, but don't worry about it. You'll get another phone by the time you notice a battery drop on this phone.

Ideally you should be charging the phone when the battery gets down to around 40% and charge it to almost full, 97%-99%

I've always felt that the less you charge s phone, the better in the end. And once its done charging, unplug it. So don't leave it charging over night. I have a timer set up so my phone charges only for a few hours a night then shuts off. When I wake up, my phone is usually in the 90%+ range

That's simply not true.

Lithium-Ion batteries are designed to be used - not to be used as permanent storage (thats why batteries in always-coorded laptops die faster)
(storing li-ion batteries should be done at 50% charge, never 100% nor 0%... )
Li-ion batteries should never get below 30% and likewise never hit 100% - The reason why, is because you are stressing the battery the most in the extreme ends... an almost empty cell is stressed when it has to deliver .. and an almost full cell has to charge at higher voltage to reach 100%.
So the best thing you could ever do is to charge from 30% to 95% if possible.
Regarding the amount of charges... with Li-ion you shouldn't think about the AMOUNT of charges, but the SUM OF HOURS that your charge..
so lets say you charge 500 times a year and you in total charge for 500x4 hours = 2000 hours of charging..
the battery usually last for 5.000-10.000 hours of charging ..
The reason why it is so, is because charging li-ion burns the Kathode (or Anode, can never remember) -- and when its all burned off, the battery wont charge anymore ...
Discharging too fast, also burns the Kathode (Anode) !!

Everyone is all over the place in this thread. The two things I will tell the OP to do is not leave the phone plugged in over night, and stay away from 100 and 0% and you will be fine.
But even if the OP keeps treating his battery the way he says, it will be okay. Not ideal, but still okay.
I personally try to keep the phone between 30-80%.
