Okay, been kicking around with the 3d for a month and decided to keep it. I am giving my ex the evo, but it looks like its not charging. After a complete battery drain does it take a few hours before you see the charge light?
Are you using the USB charge? It might not be getting a full charge due to the power restrictions from the usb. Why not try using a car or wall charger. Worst case scenario, give me the phone so I can try to fix it and I can keep it. lol

funny... been using the wall charger. I pulled the battery for 5 min and replaced -- still no charge light. Switched usb cords. Don't know why the battery would die after only a month of no usage.
It looks like you might have to get a new battery. You could still give it to me so I can get the evo and then have it fixed for myself lol but it's only because I have a spare battery.
The battery is completely drained. the phone wont charge it on its own so as to not damage the battery further. Take it to sprint, they can "boost" the battery to get the phone to charge it again.
When lithium ion batteries aren't in use they should be charged then stored in the fridge in an air tight bag. EVO batteries have circuitry designed to protect the phone that will resist charge if need be.
It is nice to be important, but it is more important to be nice.

for some reason, everytime i charge my battery, it stops at 96%..i would then need to unplug and plug the cord back in to let it finish the rest..do i have a bad battery? i tried different cords on pc, wall charger, car...
not sure if it's because i installed something on my phone that might up messed up some reg files or damaged something..
anyone else having this issue?

I have posted some weeks ago the same problem.
It looks like a charging bug courtesy of HTC that i allready reported to HTC Spain, but they don't know what i am talking about
I know you probably wan't the most battery life you can get but this might be a good thing! I'm going to test it out soon!
If you read up about lithium polymer batterys, like the ones in our phones it seems to sugest that keeping the battery between something like 40% and 80% charged and charging more frequently for shorter periods of time rather than leaving it on over night will prolong the batterys life.
If you want to be really geeky and store the battery properly at any time, charge it to 60% and put it in the freezer (in a bag).
I'm not sure about these or any other phones but laptops didnt use to come with overcharge protection (Ithink most do now) meaning that when the battery charged to 100% it would just keep charging and fry it! This might be HTCs overcharge protection!
Cheers
Tom
i noticed if i do leave it over night, it goes to 96%, then i slide to unlock (s2u2) and then it starts charging again, and then it reaches 100%...

On every PPC that i have owned before, as soon as battery gets fully charged, it keep fully charged, and the power is taken from the wall charger/Car charger while you keep it pluged on.
Why you keep trying to trick us with those % , if you know that this Rhodium is a BIG BUG ???
Cheers
Sorry if this subject has been beat to death, but i'm new to the EVO. Actually the fone belongs to a good friend of mine. She was told that if her battery gets so low that the fone shut's down, she'll need to bring it to a store for them to get it restarted. This seams wrong. I know with my Droid1, D2, And DInc1, all will power up as soon as they're plug'd in.
Both my friend and i are rather intelligent, and if a sales rep at Sprint can reboot it, so can we. (after all, her is the only fone i mentioned not rooted)
What i'm looking for is:
1. Does this condition really exhist?
2. If so, how do I! reboot it?
Sometimes the Evo's battery will drop so low that it won't charge - it happens fairly often. You'll need to take the battery to a Sprint store so they can boost the battery.
An external wall charger should charge it too. It isn't a given that the battery won't charge after dying completely, it's just a possibility. I have never had it happen to me, but people start threads about it all the time thinking their phone is bricked.

I have never heard of this happening and have never had it happen to me. Did a quick search and you may want to have a look at this thread HERE to see if you can find some answers.

Exactly what Jane said is correct. It will get so low sometimes that it will need to be "boosted". I have a battery right now that my wife let get so low I can't do anything with it so I just gave her my spare.

No it isn't. Its the protection circuit in the battery. In an undervolt (as in an overvolt) condition the charging circuit shuts down.
As was mentioned earlier, a wall charger can sometimes push the voltage high enough to "revive" the battery. I believe it depends on the battery.

Exactly. Or if you're like me, an aggressive under volter, when you let the battery hit 0 and it auto shuts down, once plugged in, the charging like blinks for a about a minute before it stays solid, which is normal.

I'm sorry I can't link to the secured site bug list for the Evo however I service 10-20 Evo's a week where the owner has let the battery die to the point where the phone won't power or charge the battery. Pull the battery and drop it in a HTC Hero/Touch Pro 2 or external charger and it will charge but simply will not charge in an Evo. This does not affect all Evo's. I'll say again, this is a known bug.
I'm feeling pretty doomed too! I ordered two batteries plus a wall charger from ebay and have been charging it but it = ZERO! Plus I tried to charge the stock battery with the cable, and it still never charged! I thought it was the cord, but when I plug it into the pc, the usb de-bug still comes on. Earlier, I was on the phone with my bf, and dead it went when it was at 81% charged and I was on the phone for no more than 15 minutes. WTF IS WRONG WITH MY PHONE!? Rooted.
I was wondering if it was possible to have the primary source of power be the USB port versus the battery. I tend to leave my devices plugged in a lot more than I probably should and figured if I could do this it would save on messing up my batteries. It's kind of like having a laptop plugged in without a battery (if you don't really take it out).
Doesn't really help, but if you charge your battery to 100%. you can pull it out as it runs on the usb port from then on. Only worked a few times for me

That's not what I was trying to get at. I was trying to avoid using the battery versus continual draining/charging it. I tend to use it as my hotspot at home for my primary internet connection and sometimes music.
My thought process was if I didn't constantly use the battery I'd keep phone temperature low and not mess up the battery.
Have you ruined batteries in the past by charging them/depleting them? Honestly, I have mine on and off the charger constantly. Today I used my phone to listen to Pandora most of the day and about half way through the day I video chatted with a friend and had it on the charger. I took it off the charger, ran around a little bit away from my house and then came back and it currently sits on the charger again.
From my experience with it, I've never had any issues with keeping it on/off the charger periodically through the day. I am also using a 3500mAh extended battery, but I did the same thing on the stock one.
I understand you are trying to keep temperatures low and play on the safe side, but unless you are noticing unusually high temperatures or something, I wouldn't worry about it being on and off the charger.

Yeah, if you're worried about the battery crapping out, I wouldn't. I've had mine on charger every night or every other night, and it's still like new.
Heck, even if it did die on you, you can get a brand new OEM battery on eBay for less than $6 shipped.
Quick tip on battery. If you go online and sprint chat with a representative, just tell him or her your battery life is no good on your phone. Then he or she will tell you go to buy one then get back on chat and sprint will credit your account. I bought $60 battery extended with case and got credited $60 on my bill
Plus now I can charge one night and last two days!

What is best in terms of battery longevity?
1 - Wait until battery level fall below a certain level (and which % is ideal to start charging)
or
2- Charge the battery as frequently soon as possible
Thanks for any advice
Lithium batteries last longer if you do not disharge them all the way..
I don't have reference material handy. If you really want some, I will try and find some again..
But basically charge the battery whenever you can or at least do not let it go below say 20 or 25 percent if you are concerned about that. Since our devices have a replaceable battery I do not stress out over it too much. If I cut 6 months off the battery and it only lasts me a year or so, I can always just put in a new one, they are not that expensive..
Now on a device without a replaceable battery is where you really have to be concerned..
Drain till 20% then recharge it. Best way to use lithium battery.

yea could be, just don't discharge or overcharge the battery :good:
i haven't looked into it lately. but i'm pretty sure our phones don't discharge the battery till it's technically at 0% (~3V)
i'll run my phone down tonight and check it with a mutlimeter to verify...
i wouldn't be surprised to find out the phone stops charging the battery before it's at a true 100% either. so i guess i'll check that too.

I was also puzzled by the warning of overcharging issue. I read somewhere that the GalNexus has an electronic which prevents overcharging. I am very interested by your verification if that is true. Because frankly, it would be very inconvenient to wake in the middle of every night to disconnect the charger.

there are wall chargers that have timers on them, they shut off power after a custom time
You can't overcharge a phone by leaving it plugged in all night, the charging circuit only allows it to charge to a certain point. You can overcharge a phone by plugging it in everytime it hits 90% because you're being all OCD about it. Over time that will screw up your battery
The main thing you want to avoid is heat, which will seriously degrade the life of the battery. I only charge my phone once a day(before I go to bed). I've been doing this since I got my first Android device(well, my Nexus S had to be charged like 3 times a day :| ) and have never run into any premature battery failures.

Quite the opposite is true, regarding the second part of your reply, actually.

Actually, it's never a bad time to charge a lithium battery because the charge you are using is always the oldest added. Consider it as a bucket with golf balls and a hole at the bottom. You load golf balls from the top and use them one at a time from the hole on the bottom.
All lithium batteries have circuitry built into them to prevent overcharging but at the same time the circuitry needs power to operate. If you drain your battery down to nothing and leave it uncharged for a long time the circuitry will drain the reserve and you will not be able to charge it at all.
Another fact about lithium batteries is that you can charge them more times than their natural life span. So as soon as a battery is manufactured it starts to go bad just sitting on a shelf. So buy them fresh. They have thousands of charge cycles and only about 2-3 years life. So even if you charge all cells inside 2-3 times daily (remember the bucket analogy) that's only about 1,000 charges in a year.
Also, you could plug your phone in and out 100 times during one day and still not complete one full charge cycle.
Conclusion ; charge it whenever you can, whenever you want. You'll need a new battery in about 2-3 years anyway in which time you'll most likely get a new phone.
Thanks obsanity. Oh wow, this is indeed even better. Thank you very much for the technical background explanation.

the cheap ebay batteries use a cheap/inferior chemistry. they may be capable of the same Mah as stock for example when new, but i wouldn't count on it to age as well compared to OEM.

I would say they are not only old but also fake claims of capacity. It's actually hard to measure how much a battery can hold so they take advantage of it. Who's going to prove them wrong?
system shutdown occurs on the Galaxy Nexus at 3.39 volts (assumed, measured voltage with no load is 3.42)
in theory you could get a bit better battery life at the cost of cell longevity by running it down to 3.2 volts. assuming the system could continue to function.
EDIT: full system charge is 4.2 volts, as expected. i don't see a practical benefit to modifying the system to run at below 3.4 volts, even if possible.
I found LG's Battery Charging kit BCK-5200 on Amazon https://www.amazon.com/dp/B01M5C23SV
I haven't bought it but am thinking about buying it along with the phone someday soon. Does anyone have this or something similar? And is it realistic to just have a spare battery, charge that, and then swap batteries whenever appropriate? That way I wouldn't need the charge cord under daily use.
Realistic?

Because I bought the phone specifically because I wanted one with a removable battery, I also purchased the extra battery with charging kit when I purchased the phone. I thought it was always a good idea to have an already charged extra battery just in case the situation arose where I drained my battery and needed an immediate charge and did not have access to a charger and/or did not want to wait for the phone to charge, even with the fast charging.

I bought the cradle and extra battery when I got the phone. I think it's totally worth it and the only way to really use this phone. I hate waiting for my phone to charge so now I just swap batteries on the fly.
For the record, I bought my H918 as a certified refurbished device.
I found that the charger (with a type C outlet to the phone) that came with my phone was delivering a spotty current. The phone also came with one charge cord, with USB C on each end. That was going to be useless to me since all my other power sources were type A.
Since then I bought a set of 3 adapters so I could use all my micro USB cords. As it turns out, none of them are effective and deliver extremely low current and don't allow me to connect to my computer.
No matter, as I'd also ordered a different package of 2 spare batteries and a wall charger for one battery. The guidance said I should let the battery charge a full 12 hours before I swapped it in, so I did that.
Ever since then, my solution has been to just switch out the battery when it's empty, and by then the battery is charged. To clarify, I feel like the battery charges on the wall better than 12 hours empty to full, but even if that was an issue I'd still have another battery, and I'd still have the usual charge cord option.

The phone should fully charge in around 2h if fast charging is operational. Do bear in mind that the screen needs to be off for fast charge to work otherwise charging rate drops to 5W
I have the kit and that charges at around 8.5W which was a surprise to me as a similar kit for the G4 averaged half as much
