i'll be getting my incredible in a few days, and i've heard varying reports as to how to charge the unit right out of the box.
from what i understand, li-ion batteries no longer have a 'memory' feature that requires a full charge before any use. i've heard a few folks mention that the phone should be charged for as long as 6-8 hours before use. some say to do so with it powered off, others say it's cool to play with it while it charges, and still others say to power it on but not touch it.
what has everyone done with their new phones and what kind of results did your method produce? again, thanks in advance.
When i got my phone i just plugged it in and charged it while it was still off. Then i unplugged it and let the light turn green again then turned it on. Incredibles need a bump charge to actually reach 100%. This means when its on and charging after it finishes you have to unplug it then turn it off and plug it in again and wait for it to finish
Just charge it when you get it. The battery doesn't store memory like older ones, but they still are only good for so many charges.
Charging new Incredible
I followed goht its lee's directions and worked as he says. Mine showed green.
When finished charging. Unplug, turn off, plug charger back in. Is sitting there charging up to full with amber.
as always... fiftybucks
I used mine during it's initial charge so it was getting ready.
If you are anal retentive, leave it off and bump charge it for 72 hours.

Hi every one,
As far i know, there is a BUG on every official ROM for European GSM Touch Pro2.
When your battery get full charged and keeping it plugged to the wallcharger, then your Pro2 start taking the power from your battery and NOT from the charger.
This can be checked by yourself and you will see that even with it connected, the battery in running down charge, till you unplug it and plug it again after some minutes/seconds.
Yeah, I have noticed it as well. Anyone have a solution?
Not a bug. LiPoly's do not like being trickle charged, therefore the charger turns off.
I have not verified it on the TP2 but I suspect that if you let it sit long enough the battery level would drop to some level and the charger would charge it back to 100%.
This is a rather good new if it can manage battery loads cycles...

It oughta turn the charger off and run the device from the mains, though, not from the battery. Is it doing that?

No it is NOT doing that, so to me it is a BUG.
just thought i would add this
for some reason on saturday i charged my phone via usb/pc and it lasted less than 24 hrs
so on sunday i drained it and charged it vis the plug
its still going noe
72 hrs 23 mins in stanby 30 mins talk and 4 hrs 7 mins use since 17.43 on 18/10/09
is never been this good so i thought it may be the new rom

Lithium-ion
(Li-ion)
Do charge the battery often. The battery lasts longer with partial rather than full discharges.
Do not use if pack gets hot during charge. Check also charger.
Charge methods: Constant voltage to 4.20V/cell (typical). No trickle-charge when full. Li-ion may remain in the charger (no memory). Battery must remain cool. No fast-charge possible.
Rapid charge = 3h
also i have read some where on xda that once it reaches 100% it'll stop charging

You know of any other modern phone that runs off the mains without the battery? None of my last three phones would without the battery.

My Kaiser will. It turns off when you pull the battery, but you can turn it right back on.
Every one is talking about battery and it's components but no one speaks about that with charger pluged in, it should supply power and by pass the battery once it is fully charged like others models do.
sounds like you all need to do warranty exchanges for that lol

Have in mind that once the battery is fully charged, it never go to charge again till you unplug the cable of your wall/car charger... so what will hapen then???
hello anyone know about the issue with the battery ok when i charge my euro tp2 all night and when i go to start>settings>all settings>system>power i then click on the infomation tab and under last full charge i get "not applicable" and get 0 hours and 0minute for the rest
im running the offical htc 6.5 rom
To me this sounds CRAZY. So people are saying that when the device is fully charged it starts to use its battery, thats just crazy... So basically charging it overnight leaves you with "almost" full battery in the morning...
I havent noticed anything out of the ordinary, and every morning when I come and take my device from the charger the charging light is green (opposed to the orange when started charging) and the battery shows to be 100% full.
I will check this again in the morning as I havent really paid 10000% attention to it, but I think I would have noticed the weird behaviour…
noticed this since day 1. my dash didnt do this. i did notice that a soft reset will resume the charge.
This is normal behavior for battery powered devices.
When it's plugged in, the charge circuit charges the battery.
The device itself always runs off the battery when it's available, this is why some devices won't power on without the battery installed, and many devices won't power on with a failed battery installed.
Laptops do the same thing, though they can switch to AC only without losing their state.
It's a holdover I think from when electronics couldn't switch between power sources fast enough to not lose anything (I remember the original game boy would reset no matter what if you tried to switch between batt and AC). It's possible that cell phones can't make this transition since there isn't really extra space to stuff in the bits that allow this (some large-ish caps).
I've also heard that this reduces wear on the electronics, because the voltage is more reliable, but I've never seen that documented.

I don't think this is true for (modern) laptops. All the macbooks and thinkpads that I've owned had a feature that if you plug it in while the battery is above X% (usually around 96) it will not charge. It even gives a message saying "Not Charging" in the battery status. The battery percentage then stays constant no matter how long I use the laptop, so it is not DIScharging either. Therefore it must be running from AC. If it can do that, I doubt they would have it run off the battery as soon as it is charged to 100% on a full charge cycle. I think any time AC is plugged in, a modern laptop will run from AC rather than battery, regardless of whether it is currently charging the battery. However, that's just my theory from personal observations.
Does anyone have a link for the thread that discussed the correct way to wipe battery stats when upgrading to a new Rom? I remember it went something like drain dead, charge to full, drain dead again then charge to full and wipe stats. I can't remember the complete process. Thanks for the help.
Sent from my PC36100 using XDA App
I've seen a couple different threads on that here, one saying discharge fully then charge while powered off, and the other saying to do a full charge "conditioning cycle". I did the latter and it seems to have made a difference.
Here's what I did:
Charge the phone fully with it powered on
When fully charged, disconnect cable
After green LED goes off, power the phone off
When phone is fully powered off, reconnect cable, amber charging light should be on
When LED goes green, disconnect cable
Repeat previous two steps 10 times
After 10th cycle, boot into recovery and wipe battery stats.
I am using Amon Ra recovery which has the wipe battery stats option under the Wipe option. I never did this when I had Clockwork recovery installed, so I don't know if the option is in the same place.
Being an electrical engineer, I find this business of battery conditioning interesting, along with the Ni-Cd "memory" vs. Li-Ion "no memory" issue. If anyone has found a decent physics-based explanation as to why these things do or do not have any basis in fact, I'd appreciate a link. Yes, I'm too lazy to Google it at the moment.
Hmm, I may have to look into this again. I charged my phone all night (powered off) and unplugged it this morning. I did nothing with it this morning but turn it on and look at it, then put it in standby (quick press of power button). It lost 16% of charge in less than 2 hours!
I'm running BS1.2 with the Baked1 (low voltage/best battery) kernel.
Damn, just installed System Panel and found that my CPU is at 100% constantly!
I'm trying this now. The longest I've pushed my battery was 22 hours... and that was with 39 minutes of screen on time, lol. In standby almost the entire 22 hours....
Ok, I believe my issue was related to a camcorder problem, my CPU usage has dropped back to normal levels after fixing that separate problem. After my battery recharges fully I will see what happens with the charge.
the other methods to do "calibrate your battery" (which isnt really calibrating the battery but the battery stats of the phone so it can accuratly judge when it stops and starts charging)
1) charge the phone to full
2) unplug and use phone till it shuts off from no battery (do not plug in until it shuts off)
3) charge phone to full again with out unplugging till 100% (check under about phone > battery it shoudl say full charge there)
this should reset the battery stats.
the last method is one from HTC
1)Charge the phone for 8 hours uninterupted with power on
2) turn off the phone and charge for an additional hour
3) turn ont he phone unplug it and let it sit for 2 minutes then plug it in for an additional hour.
all 3 methods listed should help. I personally dont like the x10 method because it has the potential and basically over charges the battery to make sure it is acctually at a full charge. It is much faster then the other 2 methods though so to each there own.
Dont waste your time on...
plug/unplug 10 times. It really doesn't recal the battery.
the unplug/plug 10 times.
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
You are good to go!
If I tether during the day (5+ hours) a lot, is it bad on my battery? Isn't that like a constant charge or does once the LED turn green it stops trying to charge?
Thanks.

the evo doesnt do a trickle charge so when the light turns green it stops, this is why you will almost always drop 1-5% battery rather quickly.
Are you sure? My light has been green for a while, and my phone battery status says 'Full'.

There's a lot of confusion over how the battery / charging circuit works and how it reports. My advice is to just charge until it's green and full, then unplug it. If you leave it plugged in all night, unplug it for 10 mins in the morning, then plug it back in to top off.
That doesn't really help me SilverZero, my question is only if leaving it tethered (which means connected to USB) is bad for my battery.
Well on mine i would check it every once in awhile and i would see that once it get downs to under 90% that it would charge again till it recognized that it was full again. So based on that i dont think you should have to worry about it. It seems to only draw the charge when needed. I also leave mine plugged in alot when im home so its good to go when i leave and havent noticed a loss of battery life at all.
You guys don't want the charger to trickle charge. Li-Ion does not accept overcharge, even 0.01C (15 mA on the stock Evo battery) will cause it to vent and probably combust.
So does "calibrating the battery" calibrate the phone or the actual battery?
I ask because I have 3 spare batteries, wondering if I have to do this for each of them??? They are all standard size, one of them OEM
I have browsed the threads on the issue with the bump charge, but not a lot of people complaining about it so it made me think there was a fix. I cannot find the fix if it exists. The only issue I see people complain about is the length of time it takes to charge, but I'd rather just get a FULL charge with the phone on instead of having to charge it while its off....
I haven't heard much about it in a while, either, but did notice this with 2.2: Bump charging still works (as in, the LED turns red again when I turn off my phone and charge it) but the charge doesn't last as long as it did on 2.1...UNTIL I plug in my phone again. Then it takes a while to charge back up to 100, but then stays charged. It seems like bump charging now tells the phone that it can hold more charge, but it doesn't happen until you charge up the phone again while it's on.
I get a lot better life just charging the phone while it is off, at night.

thread title is Battery Recalibration
im trying those instructions. I hope that deleting the battery stats will force the phone to "bump" charge while still turned on rather than turning it off to get the extra juice
I've tried the battery recalibrate thing, didn't seem to do much for me...
...
Bump charge still works.
The kernel lets the battery charge only so far, and if you really really really think about the bump charge solution, it is simply "charging with the power off". Then the kernel is not so much in charge.
Ironically, if you charge with the power off, and then you turn it on but leave it plugged in, you will start expending the battery even though you never unplug it. It will ultimately settle at the level that a powered-on-not-bumped battery would settle at fully charge.
Problem:
I have been reading as many posts as possible but I haven't come across my exact situation. I apologize if this is posted elsewhere.
I am running a rooted Dinc using CyanogenMod 7.0.3. If I charge the phone while it's powered on, the amber led turns green as soon as the battery indicator hits 100%. However, recently I've noticed that if the battery is close to being full, say 90%, and i power it off to charge it, it actually takes longer for the amber led to turn green. It might take 20-30 minutes longer.
I've also noticed the amber light turn green when the indicator only showed 92%. In trying something different I also noticed that if I charge the phone while it's powered on, then turn the phone off, the led goes amber and takes another 20 minutes to turn green again (I might be accidentally bump charging in this example but I'm not sure).
Attempted Solution:
I've read that a battery recalibration might help. I tried one method that requires the battery to be pulled after a full charge, but my phone won't boot while plugged into the wall if there's no battery. Then I tried booting into recovery, where I found an option to reset the battery stats... which I just did about 5 minutes ago.
I'm going to see how things go tomorrow, but is this normal? Has anyone else experienced these things? Thanks.

The kernel and the hardware charge it in different ways. That's why there are differences. DInc is famous for ending charging before the battery reads full. There's already a thread on that. there's not much point in getting hung up on how that thing charges. Be glad yours isn't like mine; a battery that discharges faster than it charges. Seriously.

Before I had a fast charge kernel (thanks Chad!) Using GPS with the stock VZW car charger, my battery would go down while it was on the charger!

On AOSP roms, the LED will turn green at 90% and charge slower from 90%-100%. Perfectly normal, and I think on any rom it will charge slowly from 90%-100% to protect the battery.
The battery will charge further when you turn the phone off, what you described is what's known as bump charging. If you do this, you should notice a slower drop from 100%-90% than usual, because the battery is charged to a "true" 100%. When the phone is on and charging (above 90%), it simply keeps the battery above 90% even if it says it's fully charged, and this is why the inc is notorious for the quick 100%-90% drop.
If you do a bump charge and then clear the battery stats and use the battery calibration app will you need to bump charge again or will it know what the true 100% capacity is and keep the droid lasting longer. Not noticing much of a diffrence when i went from 1300 battery to a 1500. May get a bigger batter that'll fit the stock battery door cause I'm trying to get the best battery life i can get.
Thanks guys, I appreciate the help. I think something else that has thrown me off is that before I rooted the phone I wasn't able to see the actual battery percentage in numbers... all I could see was the battery icon. Things are now making more sense.
After recalibrating my battery I bump charged the other day and I was able to get almost 2 days out of my phone on light usage. Without bumping, I was able to end my day yesterday at 50% under my normal usage. Which is a noticeable improvement. Normally I end the day with about 10-20%. The big test will be once I go back to work next week. The cell reception is real spotty in my classroom, which I know makes the cell radio work harder.
Thanks again.
I found a lot of answers I was having about battery charging in this thread:
Your battery gauge is lying to you (and it's not such a bad thing)
So I've noticed for a while now that when I disconnect my dInc after charging, the battery will drain almost 20% within the first couple hours (almost no use at all). I suspect that the battery isn't being fully charged when the green light first goes off. After I plug/unplug the cable and charge a couple more times, it holds a higher charge more consistently. I've read this is due to the phone not wanting to over-charge the battery, however in the case of my battery (Seido 1750), it doesn't even fully charge.
Is there any way (aside from the plug/unplug scenario) to fully charge the battery in one go? An app maybe?
My phone is rooted.
Thanks.
The battery could be losing its ability to hit its capacity. In other words its wearing down.
Nothing will fix it. There are no apps to bump charge.

Charge the phone powered on until the light turns green. Leave it plugged in but turn it off. Leave it plugged in, off for about 20 minutes, you will notice the light is still orange even though its already "charged." Once the light goes green again, unplug it and power it up. When I do this, my battery will go for 3 or 4 hours before it hits 90 percent with my regular use.

Just be aware that bump charging as it's called, can reduce the life of your battery over time.
