Just want to give everybody a heads up about fastboot on the Evo. First I'll give a little background of the things I have done with my phone.
Root & Nand Unlock
Running CM7 Nightly build #26
Custon Splash Screen and Bootloader
Nothing special about it but it was a work in progress..
Now onto the warning.
I had my phone in fastboot mode working on pushing a different Splash Screen to my phone when I realized that I was late for picking my girl up from work. Looking back now this was a dumb idea, but I decided to just leave and pick her up and I would finish when I came back. Meaning that I left my phone plugged into the computer in fastboot mode and I had the command prompt up as I was typing in the code to push the image. When I returned home my phone was off. I also realized that the charging light wasn't on. I tried turning on the screen and nothing. Tried booting into recovery and nothing again. So i decided to unplug it from the computer and plug it straight into the wall hoping that might help. I was wrong. 30 minutes later still no charging light at all. Not even blinking. Not exactly sure what caused the bricking of my Evo. If it was leaving it in the fastboot screen to long, having it plugged into my computer, having the command prompt up or maybe a combination of all of them.
So moral of the story is don't do this lol.
Wow, sorry to hear that. Have you tried removing the battery for a couple minutes? then put back in and plug in to charge?
My sisters phone was absolutely dead and wouldnt come on and no charge light. It took several attempts of pulling the battery, re-inserting it before the charge light came back on. (If im not mistaken the phone does not charge in fast boot, so maybe your battery is super dead like hers)
Yea, I would definitely try a known good battery before letting your Evo RIP. Sometimes li-po batteries get dead to the point that they wont take a charge.

Fantastic call!!!! My girl also has an Evo so I stole her battery and put it in my phone and presto it works just fine. So now I have my battery in her phone on the charger. It has been a little over 2 1/2 and still nothing. So I am thinking that the battery might just be permanently dead. If that's all that happened then I am satisfied. I can handle buying a new battery but I really didn't want to get a new phone. Thanks to both of you guys "elegantia" and "k2buckley". I appreciate your posts

Glad to help, and glad you got it going again! What a relief for you! Yea, these batteries don't like to die completely, despite what some people say. The fact is, lithium polymer/lithium ion batteries don't like to be drained to 0. But at least it's just a bad battery. Check on ebay, I've heard good results about some of the cheap ones on there. And best buy also has a 1750mah battery, that is the same physical size as stock, but has a little more juice (stock is 1500mah). Good luck.
You can pick up a brand new OEM battery off of Amazon for $13. I'd go that route before the 1750 mAh batteries off eBay. The tests I've seen show they actually have less capacity than the stocker.
Also, this may be kind of pseudosciency but try putting the battery in the freezer for a few minutes and then popping it right on a charger.

It's so wierd because my phone was fully charged when I left the house. So unless fastboot drains your battery like "super quick" I am shocked to say the least. I'm willing to try anything with the current battery I have so I might take the advice of "eventer289" and throw it in the freezer and then on the charger. Not sure what I will do yet if I have to purchase another battery but one thing is for sure, my girl is definitely not going to let me keep her battery so whatever I decide I am going to have to do it quick lol. Thanks again for all the advice
Let me know if it works. I've read about the freezer thing to revive lithium ion laptop batteries, so I figure what the hell, give it a shot.
Your battery got to low and that's why it won't charge it, I had the same thing happen to me last week. I just cleaned up my phone using my spare and took it in to sprint with the bad one back in it. They gave me a new one for free.

My girls phone isn't rooted. So I might just take hers in with the battery and do this. Not a bad idea at all. Thanks
Update- Have had battery plugged in for four hours now and nothing. So final conclusion is that the battery is shot!!! Sprint, here I come lmao!!
yes.. take it to sprint.. you have 1 yr warranty..
99% sure they will just give you a new battery. if they have one!

That's wha I'm hopin
The problem is, I think in certain modes - such as fastboot, the charging code isn't present. If you leave the device unattended, it drains and drains, even if plugged in (notice no charge light in recovery mode either, when plugged in). As stated, if the voltage falls too low, it won't accept a charge. There's probably some way of reviving the battery, but why bother. Hopefully the OP learned his lesson.
Lithium chargers have a built in safety that will check for minimum voltage before attempting to charge the battery. The EVO has this safety mechanism built in. The method to bring the battery back is to charge it in a dumb charger until the voltage reaches high enough for the EVO to recognize it as a proper battery and then charge it. I've never had to do this on a mobile battery but have done it a few times on Lithium Polymer packs for R/C planes. Some cheap Chinese chargers don't check voltage before charging. You could try jumping the terminals from a good pack to the dead pack for a few minutes being careful to jump the exact same terminal on both batteries. It's worth a shot. Excessive discharge can ruin the battery life going forward but you won't really know until you try. I would monitor both packs for excessive heat just in case but in all likelihood you'll be fine connecting them for a few minutes to boost the voltage on the dead pack. You can always get a two pack of batteries and an external charger on eBay for around $20.
^^^^ good info.. on why it is not taking a charge
Probably should change the topic now since this has nothing to do with fastboot. Simply having cmd open with stuff typed in it won't do anything to your phone.

I am scared that my battery will overcharge again! Cause the battery is new I wanna take care of it so it stays new!!! the thing about excalibur is that it tends to overcharge!!! is there application or anything i can do to prevent overcharging?! Thnxx in advance!
It should not be a problem. Do not worry to much about it.
it does happen!!! cause its not a cellphone that says its fully charged and stops charging!! the excalibur juss keeps on charging!!!! thats why my old battery is effy and turns off itself out of nowhere which i hated so much!!
what on gods green earth would make you believe that out of all the phones produced, htc would make 1 that never stops charging? id like to see some data on that to back up your claim. please dont say "a friend who works for so-and-so told me"
Dude it stops charging when the light goes green man on the top. It goes from orange to green (greening meaning that its charged). You can also verify if you look under the topbar with the batter (once the phone is charged the battery turns regular but when the phone is charging there is a USB cord like icon next to the batter or going around the batter, once the phone is charged this icon leaves just showing the battery by itself.
Humm, never get tired of hearing this. Todays Li On batteries cant be "over charged". They are microchip controlled. They cant be damaged due to "undercharging" either, thanks to that wonderful microchip thats installed.
No doubt some CSR (customer support rep) told this person that his battery was damaged due to "over charging" (a standard reply by CSR when they dont understand why a battery wont hold a charge is "it was either overcharged or undercharged to many times").
Dude - read more about Li-on .
There is no way to overcharge it .
The battery life is no so long - 8-12 mounths anyway.

Haha I was trying to tell him that in more basic simple way lol.
my battery started giving me problems not long ago, just got my 2200mah battery in today to replace it. i had to keep it on house or car charger the entire time else it would power off randomly (usually within 2 minutes idle, less if touching keys)
battery was replacement with replacement dash, stupidly kept the replacement battery instead of my less than a month old one.
as for "overcharging" my dash stayed on the charger that came with the phone, for a week straight (vacation time and lots of video games) and then stopped working, i know lion arent to overcharge, but alot of people have this same issue . chalk it up to a bad battery or well use battery at the end of its rope.

No matter how much you take care of it the battery will last for a maximum of 1800 charges or so. As a lithium battery that means it increases life by 3x over nicad batteries. I have a dash and know 3 other dash owners and not one overcharges. My friend and I had to change our batteries but due to its life cycle and the battery dying a few times. When your phone dies like that generally that means the battery cannot support the same charge capacity and is need of replacement.
These batteries are dirt cheap anyway.
I got a OEM Simplo for .99 on Ebay, plus there are tons of after market ones out there also.
I keep one in my wallet as a backup.

I know! Not to mention that a lithium ion battery is designed to be more efficient anddesigned not to overcharged when full.
Factory Defect!
And it doesn't seem to charge pat 70%. I'll leave it on the charger until it is at 100% (not 90% like some people have issues with), and then when I take it off, within 2-3 hours I am down to anywhere from 72-68%. This isn't with heavy use, for example this morning it has been off for 2 hours, it is at 75% and I did nothing with it except read one email.
Just testing things out, I charged it while the phone was off, and it seemed to discharge slower.
Is this a common thing with these batteries or is mine somehow defective?
Thanks.
Did you recalibrate the battery in your recovery? Charge to full, boot recovery, wipe battery stats, then let it run till it dies.

I did, but I might try that again. It may not have been actually at 100% (I didn't turn it off, because I didn't know about the issue when I calibrated).
All the other threads had the answer but.....
The driver that has the stats for the 3500mah battery isn't there.
They only included the driver with stats for 1500mah.
If you want to fully charge the battery, you have to do it externally. Even with phone powered off, it may not fully do it.

The evo can't charge the seidio or any non-htc battery properly. Get an external charger and watch your battery life increase with every charge. I don't even wipe battery stats anymore.

That would make sense... I might ditch it then, if I can't reliably charge it 100% because the battery door is pretty hard to remove compared to the stock one and I don't want to end up breaking it one day.
Is that something that would be in the ROM? I'm just wondering if it's worth holding out hope for someone to write a driver for it in CM6 or something.
Yeah I just let it charge until it turned green, turned it off and let it charge until green again (another half hour or so), unplugged it and did it again and it is now at 89% after literally just wiping the battery stats and booting up.
Maybe I'm just being too neurotic about it. It lasts 2 days, I guess I should be happy, but with the stock battery I got 30-36 hours using CM6 and Snap, so I was hoping for more than that.
Been having similar issues did a full wipe the last Rom I loaded and now two hours after unplugged I'm still at 100% so who knows.

It's hard to say if it's in the rom because the evo itself will not charge any non-htc battery correctly even when it is turned off. It seems there are both hardware and software controls to ensure nothing but the evo battery gets charged correctly.
Here is what I did about the battery door http://forum.xda-developers.com/showthread.php?t=786101
The fact that this battery has been out for so long, so many people have it, and HTC knows about this flaw and hasnt done anything about it is absolutely pitiful and HTC should be ashamed of themselves.
As everyone has said, the only way to get a proper 100 charge is in an external charger. The closest way to to do it in the phone is to leave the phone charging overnight, unplug it when you wake up, and plug it in about 5 minutes later to top it off. Youll get close but it still wont be true 100.
Either way, the only way to properly charge any extended battery for the evo is in a wall charger.
dang i should have canceled my order. Seidio's stupid cancellation policy made me not do it. "cancellations after 2 hrs incur a fee" Now im going to have a Evo with a pot belly and a empty stomach. BS

If you can get it charged properly youll be happy with it. You just have to work around HTC's dumbness.

Yeah it seems like I guess it's mostly HTC's fault in this manner. I'm back on the stock battery for now. I might just keep the extended battery at ~60 (apparently the best way to store Lithium Ion) and when I plan on heading out for a weekend trip or something like that, I'll charge the battery up and put that in my phone.
For everyday use, having to remove the battery to charge it sucks.
What would be ideal is if HTC allowed you to key in the MAH of the battery you have installed in your phone or something along those lines to ensure the battery gets charged correctly . I know its a long stretch but hey I can dream ROFL . This charging bug has been the one major thing preventing me from getting an extended battery . I have toyed with the idea of getting a chinese one for cheap just to play around with and so forth but not to drop the cash Seidio wants for theirs . HTC needs to address the charging issue anyways , most users that use a wall charger for their stock batteries have reported improved battery life . Its sad when a cheap wall charger from china out performs charging a battery better than a 600 dollar phone is able to .
I dug thru the code for the battery driver. There seems to be 3-4 different driver sets, but all are 1500mah or less.
It's been many, many years since I programmed, but the structure has an array of temps, max, min MAH, charge rate, and quite a few other specifics relating to battery.
I'm not sure the logic between the charge circuit, the battery and how it knows which battery is inserted, but some of this info is parsed into the logs while it's charging.
A decent programmer could probably code and recompile this into the OS. That programmer isn't ME. I switched to engineering and networking too long ago to remember enough not to blow stuff up.
This is the one thing keeping me from purchasing a hicap battery. Good to hear that it is software related though. Maybe if they got a pool going some enterprising dev will take a whack at it. Disclaimers work

im wondering if cyanogen and co can work their magic
I'm quite sure they and many others could, but not everyone has the Seidio battery, compared to the numbers of EVO users.
It's probably not worth their time and effort to bother.
What WOULD be nice is if the Seidio folks had programmers instead of just sales folks and could code their own patch for their own products.
I won't be holding my breath tho for any solution. it's ok for me, I have the external charger from my TP2 days. Plus spare batteries as well and don't mind switching when needed. I knew of the issue and was prepared for it before purchasing.

Yeah I wasn't so much prepared for it. I heard a few things about it, but nothing solid for sure, I should have done some more research. All the reviews on websites were glowing, but I usually take that with a grain of salt.
Too bad even if Seidio had programmers, I'm on CM6 so that wouldn't help me too much haha. On my stock battery I'm getting around 24-28 hours which is plenty fine I guess. Not looking forward to when the battery starts losing its maximum charge, though.
So i don't have an external charger...but i followed the instructions via seidio...
heres what i got:
Rom: CM6 Final Stable
SetCPU: 245/1152 Conservative (Freq Step = 10)

This is my first post on here,but I've been lurking for ages I just bought a Mugen 3200mAh battery from MugenBattery.com.I already know about not having to condition it(lithium ion),so I ignored the instructions about cycling it and plugged it in and used it right away,and at first it seemed okay for around an hour(I didnt use it at all up to this point,just left it there until I needed it).When I went to unlock my Vibrant from suspend(pushing on the power button),the phone shut off and seemed like it was rebooting...but it just had the first screen you see(the one with Samsung and Vibrant on it) blinking on and off,even when I plugged in the charger in this state,all that popped up was a battery that also blinked on and off.The only way to get it going again was to pull and replace the battery,and it went back on again...then did this all over again when it went into suspend and I tried to unlock it.All the while,the battery stated it had around 75% power,so I have no idea what could have caused this.I put my cheep chinese 2700mAh battery back in and all was well again,so I know its the battery,not the phone.Anyone else have or seen this problem before?This is the most expensive battrery I have ever purchased for a phone at $88.00US....I hate to think that a cheep($20.00US) chinese battery has better quality control than it....
i think you need to charge it for 12 hours first.

Thanks,you were right! An overnight charge of around 12 hours did it.This is the first phone battery I had to do that with to get them to just work at all.Seems to work just fine now Again,thank you!
Let us know how long the battery is lasting once you get a few cycles please!
Yeah, you should run the battery dry, recharge, run dry, recharge and after a few cycles your life should improve.

NO, NO, NO. PLEASE stop spreading bad information. This will HARM the battery, and will have 0 benefit. The only "benefit" you can get from this is that the battery meter on the phone's firmware will be calibrated to show a more correct remaining %. You can achieve the same by charging the phone 100% (overnight) going to clockwork recovery and selecting 'wipe battery stats'. Calibrated or not, the battery will last the same, regardless of what % left its showing.
Again for posterity, REPEATED DISCHARGING OF LI-ION BELOW 20% IS BAD FOR THE BATTERY, IT'S PHYSICALLY IMPOSSIBLE FOR IT TO GET BETTER.
I am having a similar issue with a battery that I ordered off of ebay. It's 3500mah.
When I plug it in it will turn off and get stuck in a boot loop on the vibrant screen, but if it is off then it won't turn on at all when plugged in. It has been plugged in for 9 hours so far and it doesn't even show the charging animation or anything.
Normal? Or is the battery defective?
Thanks.
Ok. After charging it overnight and still nothing, I'm going to assume its broken. Thanks.

How to use a new battery:
1. First when you received the battery,. you need to release the power in the battery, just put it into your phone without charging.
2. After the battery power is out, please charge it about 12 hours in first three times.
3. So the battery will be actived. So you can just charge it about 5-7 hours when use in the further.

I also recommend you to read the article "Everything You Need To Know About Bump Charging And Inconsistent Battery Drain" here:

So this a controversial matter, isn't it?

No controversies at all. Your info from the link is outright wrong.
Mannymal is correct on this one.
I also have this battery. By the time I got it, Team Whiskeys roms had gotten good enough to where I didn't need an extended battery for day to day use (stock battery usually has 30-40% when i go to bed), but I do use it when I travel, so I don't have to worry about using it like crazy. The battery lasts a long time, probably like 2 or 3 days if I actually tried to drain it, at least. And it's definitely adds bulk, but it's reasonably well made and feels sturdy.
My only complaint is that I sometimes cover the speaker with my finger when I want to silence it real quick, and it doesn't work with this because the cover's so far from the speaker. But that's just my weird thing.
Also, yeah, don't kill your battery. No es bueno.
What is this? How do I read?

I use a seido innocell battery and it works great after a few over night charges. I get about 8 hours average of talk time. The battery is pretty small compared to the one accessory greeks sell. Even though the ah battery ia twenty five dollars, that is like the entry level name brand battery, it will lady you a while longer than the cheap ones on ebay, but I don't knower about the ones on ebay although I do know about the one ag sells skies down charging after about 45 percent charging. The seido is charging pretty fast for me and is half the price of a mugen, the next battery I'm going to buy will be the nugent, not because I need it, just
Cause I want to enjoy it.

Yes I have searched for the answers and found some but not all. The charge light will come on to say it is charging but the battery meter does not change and says 0%. As soon as I unplug it it will die obviously. I have pulled the battery and unplugged and plugged the charger. The battery life has been fine on the battery until this. I just looked at the phone 2 minutes later and it says 99% percent charged. Now everytime I look at the phone it goes down atleast 5%. Im not sure if this is a kernal problem, bad plug, bad battery, or what.
I am running MikG 2.3 with the kernal that came with it.
Off hand, sounds like battery gone bad...

I tend to agree. If this cropped up suddenly with no changes in ROM or kernal you've probably got a dead battery. Replacements are fairly cheap, so give that a shot first. If you've got insurance, worst case scenario is a refurb which still isn't too bad. I haven't been reading about so many horror stories with the replacements.
whoa now

Before resorting to a replacement (which will most likely be 2.3 and unrootable as of now) try flashing a stock ROM and take it into a repair center. No TEP? It'll cost $35 bucks and you'll get your battery tested and replaced instead of the whole phone.
From troubleshooting phones in the past it could be the battery connections themselves. I don't think it's the charger port unless there's a short in it which you can't really check for.
I recommend flashing a stock ROM anyway, with a stock kernel. Then, recondition the battery, which is to say you should let it drain all the way until it dies, leave it off, then plug it back in and let it charge (still off) for around 5 hours. After that see what it does on the stock ROM while it's off the charger. The first 10% usually drains quickly, I would keep an hourly log just in case.
Got all that? haha
So my z play battery is acting up, mostly it dies suddenly from ~50%, but does some other strange things too, so I'm thinking its time to change it. Anyone have to change theirs out yet? What battery did you choose? I've seen Chinese knockoffs, OEM batteries and these so called "premium" x-longer batteries, has anyone tried those out before?
Attached pic of battery use. Quick drop off and guick recharge all around 50%

with batteries on these recent phones I would try to stick with OEM. Long ago with the removable batteries, I experimented widely, but for some reason, not now...
I would also be tempted to play with that battery by draining if completely a couple of times, but it may just have a bad cell in it. Was your most frequent charge by slow? of fast?
I've had it drain a few times and messed around with it, with really no change. At first I thought it was due to the ROM, for example it started when I'd plug it in to charge, and it wouldn't recognize being plugged it, I had to unplug then plug it back in to get it to charge right away, so its been this way for a little while. Maybe I'll get both and see how they compare and share my results. I've read good things about the x-longer batteries
Sorry forgot to add, I always charge it with the turbo charger it came with

My bet is your battery has a bad cell. Whether fast chargers cause this or not is anybody's guess. Grab a youtube teardown vid and go for it. (replace the battery)

Would be really interesting to see your feedback on those batteries. I've seen those reviews too, but they were too good to be true, had even the impression the sellers making them up.
Just ordered an x-longer, coming from Germany so hopefully in 2-3 weeks I'll have it. Only a few bucks more then an OEM battery, so I'll give it a shot

Where did you get the x-longer battery for Moto z play ?
I am from India and can't find original Motorola gl40 battery. The ones available on Amazon are off brand and I am.not sure whether to use them.or not.

I ordered it off of ebay, and it was ok. I dont have my z play anymore but the battery was finicky with charging, it would refuse to charge to full at times, but it did last as well as the oem one. maybe it was due to an issue with my phone, but overall it was a pretty good battery

ok thanks. i decided to go for an OEM battery replacement only. It is time taking but hopefully will be worth it.
