Help Li-Ion Battery Charging Discussion

Once fully charged, the light goes green, charging stops. (See NeoteriX's post above.)

At that point, if on, the phone will start running off of the battery but continue to show a green light. Once the battery hits a factory-defined point (anywhere from 92~96% depending on make and model) the charging starts again.

This is all exactly the same as a laptop.

The chances of your battery actually being at 100% is quite low when you remove it from the charger.

Users note that in a few minutes they lose maybe 4~8% of battery and conclude that either the battery is bad or it needs conditioning.

Many note a slower drop the longer the battery is used and conclude that initialization is necessary.

Others claimed that the charging circuit needs calibrating, as happens normally over use. The following procedure is said to calibrate things quickly:

Charge phone while on until green led. Take off charger, turn off, put on charger until green. Take off charger, turn on, put on charger until green. Repeat until immediately green when on or off.

I followed that advice and procedure and got what looked like longer battery life immediately, but don't believe it was anything more than just calibration.

I've passed this on to newer model HTC users, and for example the Desire HD crowd immediately reported that this seemed to level off any early power variability as well.

NeoteriX, others with knowledge of this info, please chime - last thing I want is to misrepresent.

Have no idea how this applies to extended batteries, I've never had the need of one.

I would recommend this for anyone considering one tho -

Are third-party cell phone battery manufacturers deceiving their customers?

BatteryBoss Calls Out False Capacity Claims!

I'm not endorsing nor refuting his claims, just saying smart shoppers ought to consider them and investigate.
 
How long does it take the EVO 3D to fully charge the battery?

I've done both Google and forum searches on the topic to no avail, so please forgive me if this is repeative.

Currently I have a Samsung Infuse and it's a nice phone, but it take the $%^& thing 8-9 hours to fully charge.

The EVO 3D really appeals to me due to it's number of factors, but if the battery takes more than a night's sleep (5-6 hours) to charge I may have to go back to the (gasp) iphone...don't make me do it!!!!!

Thanks for any/all info!

mine takes about 2 1/2 - 3 hours for full charge from empty
 
I have found that using the USB cable to the laptop takes 4 to 6 hours or more from about 20% left.

Using the 110v outlet from 20% typically takes 2.5 to 3 hours.

anybody else having the issue where there e3d will stop charging once it gets up to 100% even when it is still plugged in. mine stops at 100% and starts discharging even while still plugged in. just want to know if anyone else is having this problem.
 
Long story short: It does this by design. It prolongs your battery's life (in terms of usability over years).
 
Mods- feel free to merge with other threads if you like. Not sure where to put this....

I have been running battery monitor widget trying to figure out a problem and noticed an interesting charging pattern (at least on my phone) according to the monitor. While leaving it on the charger overnight, I set the interval to 2 minutes so I got more detailed data.

In three hours and 33 minutes sample timeframe, the phone peaked at 100% charge 5 times with 4 minimums at 95%. It sustained 100% for a few minutes before trending back down again. The phone did not linger at 95% -- It is a V-shape back up. That means the phone spent the majority of it's time with a charge north of 95% regardless of the time I might have pulled it from the charger...

I don't remember my EVO4G ever charging in this fashion. It would hit 100% and then taper for a long, long time -- hours -- and wouldn't trigger until it hit 90% or so.

Has anyone else seen this sbc-ish pattern? I realize the sbc idea is to trickle it and keep it at or near 100% constantly, but this seems a good compromise in maintaining battery life and maintaining a higher ready-to-go charge. (this, of course, assumes battery monitor widget is accurate)

Perhaps maybe SBC kernels won't add much.

*** edit update ***. I monitored charging on my 3D this morning very closely (1 minute intervals) and I'm fairly convinced that adding SBC to this phone is a waste of time (and possibly battery life). The phone, as mentioned, goes up and down from 100 to 95% and back up again. At 100%, the charger kicks off and the phone discharges normally to 95%. It then kicks in at about a 300ma charge and jumps right back to abuot 97-98% within a few minutes. The charge rate then begins to drop rapidly as the % increases. By 99%, it drops under 100ma current and down to about 50ma when it hits 100%. 95-97% took 6 minutes. 97-99% took about 15 minutes and 99-100 to about 35 minutes.

That means the probability of pulling the phone off the charger at a true charge of 97% or greater is about 90%. You have about a 63% chance you are at 99%+ Worst case scenario is you pull the phone off the charger at 95% which, statistically, won't happen very often.

My .02, FWIW is that SBC isn't worth any risk of shorter battery life on the EVO 3D based on charging patterns recorded by battery monitor widget. Note that the battery was showing something like 4337 as a total which is higher than the 4208 my EVO4G would show. There's definitely something different about this battery and I won't be effing with it using SBC kernels...

definitely not going to let my phone sit, off, charging for eight hours to 'initialize' the battery. that is false information

Hey i just thought i should let you know it isnt false information it it has been sientificly proven it is an advantage to the batterys life however if you prefer to not follow this step to exeeding your batterys potential by all means ignore this whole forum. and do not say it is false evidence when you have no proof ;)

Actually, that is false information.

You're quoting a charging process for a battery chemical formulation that hasn't been used in a great number of years.

Sorry.
 
I got a new phone and a couple of batteries. How long a li-ion battery would last without any charge? Will they degrade after a certain amount of time?
Thanks
 
yes the batteries will degrade over time. the charge depends on environmental conditions and what options you have setup on the device, such as screen brightness, BT,wifi, etc.

this thread has good info you should research.
 
Yes, thanks, but sorry the batteries are not within the phone. So, how will batteries alone behave without any charge?
 
if a battery is sitting out on a shelf with no load, it will still discharge albeit at a slow rate. battery chemistry varies form battery pack to battery pack.

if a battery is discharged, its discharged. if it gets below a certain threshold, it will need to be trickle charged at a very low rate to build it back up to the minimum charge level for conventional charging

This amount of time is highly dependent on the battery's storage temperature.
After one year at 0
 
Yes, I wanted to confirm my suspects.

So, what's the best method in order to keep a battery as cool as possible avoiding crystals formation?

Then I got these 4 spare batteries i'd like to use on the time being, they'll lose inevitably capacity, but how long they'll keep an ipotetical 100% charge at a optimal temperature?

For long term storage -

Cool part of house, don't try to store them at 100%, go to about 40 to 60%.

After laying around for a week, place each in turn to see how well they're retaining charge. That can vary by brand, age and previous use of each sample.

See what to expect, and from that, you may want to charge each from times to time to keep them viable. Some batteries will need that every two weeks, others, every two months.

For short term storage, for rapid use -

Charge to 100%. Check each after a week. Expect at least 90%, adjust refresh charging intervals accordingly.

Cool, dark place on a shelf with good ventilation ought to be fair enough.
 
I have usually kept my phone on almost all the time ever since it came out off box. Battery runs down fast so I just ordered a new additional battery for my Sprint EVO 3D on mpj last week. Wondering is it bad for the performance of a phone not turning it off? Should I turn it off at least once a day?
 
No need to do that. That's a misunderstanding of the old "reboot at least once a day" Windows 95 problems.

Use the battery screen in Settings to see if you have wakelocks (ideally you see none because they're too short to show on the line), and Better Battery Stats to see what's eating your battery.
