You guys saying that an external charger is better, could it be that the external charger is charging at a lower amperage, which would make it take longer to charge and actually let the phone charge farther before it cuts off the cycle, I run lipo (lithium polymer) bateries in my rc cars, so I have some knowledge with the batteries in our phones, look and see what your externel charger is putting out then look at your other charger and compare.

[EVO 4G General] generalExpert:
how would you know if its off? Why would it be off for 2 weeks? Why would you care about the battery if it's off?

oh of course, since you're, you know, the expert... *rolls eyes*
[EVO 4G General] krazyflipj:
It works but the only thing that sucks is that you have to do it everytime u charge...
[EVO 4G General] Kubernetes:
I've said it before and I'll say it again:

Do not charge your battery with your phone on. Either get an external batt charger or turn off your phone when it charges up past 95% or so.

Lithium batteries don't have memory, but your OS does. It's recording battery stats and will shut off charging once it thinks the battery is at 100%. The problem is that if you charge while the phone is on, the battery will never reach a true 100%--you can't top off a battery completely while the OS is regulating flow.

The takeaway from this is that many many smartphone owners are missing a fraction of their battery capacity. Your OS has never seen a real full charge, and consequently thinks the battery is much smaller than it really is. I've seen screenshots from Evo owners showing a 100% charge when the battery is only 4.12v. That's a huge gaping hole considering that a lithium's nominal full charge is 4.25v or so. (edit--in my experience, I'm at about 85-90% charge when my battery hits 4.12v, so that owner was missing 10-15% of his battery).

The whole "charge until 100%, pull and reinsert plug" trick is doing two things, IMO. One, you're evening out the charge throughout the elements in the battery, and two you're overcharging the cell a bit. If you keep it up you'll likely kill the battery (or explode/catch fire). I'd say one or two overcharge cycles is enough.

Last point says 'turn your device off', nowhere it says to turn it on again. This indeed saves your battery a lot

Seidio battery and new charging method

so, I bought the seidio extended battery and I then tried the method for charging explained in this post.

right now my battery is at 43%

Up time

27:39:31

Awake time

17:26

Ive been using it pretty frequently, like I would normally use (email, web browsing, rss reading, youtube, wifi and sometimes 3g)
[EVO 4G General] HiDefinition:
I've done this and i went from 6 hrs use to right about 11 hours and I still have 33%. it clearly works but i want to give it a few days before i make my final decision. hopefully this will be a (semi)permanent fix
[EVO 4G General] Shane112358:
I'd like to add my anecdotal experience coming from the Epic. As soon as I got a wall charger/extra battery and started swapping batteries back and forth instead of constantly charging the phone (with it on), my battery life went up for sure. So I think charging with it off or using a wall charger is what does the trick here.
[EVO 4G General] wmstwo002:
Ditto......battery wall charger puts a great charge out.

3500mAh Extended Battery + Cover for Sprint HTC EVO 4G

I got this battery and cover for less than $11 shipped and it works great. I also bought the external charger and charge the stock and the extended battery in the wall charger. Seems to make a marked differnce and the 3500maH battery will last all day with heavy usage. Only issue that I have is that I don't have a rubber protective case when the extended battery door is on like I do with the stock one.
[EVO 4G General] letshaveDEX:
I've been looking for an external battery charger but I don't know what's reliable. Can anyone help me out?

Also, I think it's ridiculous I can't use my phone without worrying about whether the battery is gonna last. None of this should be necessary.

I've tried these half baked methods, as well as custom ROMs and kernels that are "optimized", my battery life is still the same. Both AOSP and Sense. I'm gonna try using a external battery charger now to see if there's any difference.

Any help would be appreciated, thanks.

HTC EVO 4G | CyanogenMod 6 RC2 | Snap v7.6 CFS
[EVO 4G General] bolesroor:
WOW! This really worked

This is a one-time only procedure.

1.Turn the EVO on and charge it for 8 hours.

2.Unplug it and turn it off.

3.Plug it back in and charge for 1 hour.

4.Unplug it and turn it on.

5.Wait 2 minutes and turn it off.

6.Plug it back in and charge for 1 hour.
[EVO 4G General] Ares91:
Hi!

I was wondering if the charge procedure mentioned in post #1 has to performed when you charge your phone for the first time?

Or can you, hypothetically speaking, also do the procedure a few weeks after you have received the phone?

Thanks in advance!
[EVO 4G General] blkout01:
I have several batteries some new and some used. I did this on both new and used and saw the same results. So the answer to your question would be you can do this to your battery whenever you please but YMMV.
[EVO 4G General] dkdude36:
just tried it. holy ****... worth the 10 hours+2 minutes
[EVO 4G General] devnulldroid:
Yeah..i do this with my toaster, refrigerator, microwave and all my consumer electronic devices. It works too. Sure. Dials number to Better Business Bureau in hopes that HTC, Sprint or battery manufacturer will get the hint and issue a massive recall.

What a BS response by HTC..

Here want a free battery?

Between that response from HTC and Sprint giving out free batteries they might as well be saying.. Now, laydown and shutup.

Satisfy the few to keep it quiet and that way we wont have a massive recall to replace every EVO battery and poss other HTC device batteries which will cost us $$$.

Personally, I bought an extended OEM battery from Sprint and it does no better..hmm maybe a device issue..we'll see. That would cost someone even more..

Hey Guys

Does anyone know if the battery has to be fully empty to start this 8hour charging cycle or can i just plug it in with 75% battery remaining or so ?

Thanks
[EVO 4G General] marclile:
no, it does not have to be empty.
[EVO 4G General] horsovski:
I just ended first 8 hour cycle, now when i turn it off and charge it its green from the start. Its that how it is supposed to be?

I am doing this on HTC Desire HD, will these methods work here aswell?

EDIT im on the last step of the HTC method and while waiting on the "2 minutes" to pass my phone droped from 98% to 92% in a matter of seconds :( idk what else to do cuz from the looks of things this isnt working either!
[EVO 4G General] mykenyc:
This happened to me, now watch as your batter drain, when I get real low it will stop at like 7% it will stay there for like 45 minutes.
[EVO 4G General] Slippin:
well im goin thru and removing all tha apps i hardly use and my battery is at 93% but its droppin like every 2 mins or so...
[EVO 4G General] mykenyc:
Yes i know, this has happened to me too, i just deal with it, nothing wrong with your battery, seems as if the system is not reading the battery right. Just a little irritating because when the battery seems to be dying, since the battery isn't really dying the system will stay on 15% warning with the led flashing as if it's dying, but it will like 2-3 hours to officially go dead.

[EVO 4G General] DrRyder:
This is all good and all, but I would really NOT like to have to go through all that for a full charge. I use Netarchy's 4.3.2 SBC CFS HAVS - More Aggressive kernel.

I just went 1 day, 3 hours unplugged before plugging in at 11% remaining. I was unplugged for 5 hours and was at 93% during that same charge.

ggz

TL;DR: Change kernels if you want better battery.
[EVO 4G General] lrosenman:
Normal for me. Weak cell signal at office as and twitter/facebook sync. Before doing this, it would only make it 6 hours before i'd have to put it on the charger.

24 H uptime, almost 2 hr wake time, 82% remaining. Yes, extended battery, but trick is to turn off data (3g) when not needed. Performed some web browsing using wifi, sent/received several texts, about 30 min in phone calls.

non EVO user help

I'm a total noob and kinda jumped in the deep end. I have a Sprint Hero and installed CM7/Gingerbread. Even with Sense, my battery didn't last long. Now it's draining like crazy. ~20% per hour.

I've checked other threads and the Hero section and didn't find anything comparable to this thread. I tried the steps outlined by the OP and had no change in battery behavior.

Does anyone have any suggestions or can point me to a thread I couldn't find. Thanks.
[EVO 4G General] prettyboihenry:
thanks a lot dude
[EVO 4G General] Dan330:
1.. you should look in the CDMA hero section.. there are several "hero" phones.

i used to be a cdma hero user. it is a good phone if you have it setup right.

2. check to see if your battery uptime is same as your sleep time. it is on the settings under battery. if they are equal.. you phone is not sleeping.

start your search on that. There was a trick to fix it... plug in turn off plug in again..thingy.. but I dont remember. you will have to find it. there also might be an app that is causing sleep issues.

3. what made my phone.. great:

ASOP 2.2 ROM with launcher Pro.. and the Firerat Memory Partition mod.
[EVO 4G General] jneg123:
Thanks for the suggestions Dan330. I jumped right into 2.3 so when I get a little more time, I'll try going back to 2.2. May not be the "latest and greatest", but more stable and useful.
[EVO 4G General] Dan330:
well.. hell.. did not know you are running 2.3

that might be part of your problem. it aint very stable yet on the hero.
[EVO 4G General] Dan330:
over the weekend I did 2 things...on sunday..

this battery conditioning technique and updated my kernel to Nectarchy-Toastmod 4.3.2

I am running Myn's ROM.

I did not see much change on the first charge. Because I used it a lot...

today..

unplugged at 11am...@ 86% battery

i only made 1 phone call for 4 mins.

it is now 7pm... still @ 86%

that is right 8 hours.. NO change in battery!
[EVO 4G General] nomadicthoughts:
You can't honestly believe in 8 hours it didn't even go down 10% do you?
[EVO 4G General] Dan330:
i hear you... it is nutz...

but now.. it is 9pm..

it finally dropped to 85%

those are the facts.
[EVO 4G General] dkdude36:
i've had something like this happen before. it'll be at 30 in the next hour. or just shut off at 80.
[EVO 4G General] Dan330:
soo... you think the battery reading maybe off.. or stuck ..

while in actually it is still draining and way lower than indicated.

no real use..

and at 10pm.. it is at 82%

it is not stuck.. but moving faster than before.

hmmm...

but still 11 hrs.. and only loosing 6% of battery.
[EVO 4G General] dkdude36:
one way to check. download battery moniter widget and put the widget on ur homescreen (so it can stay open and monitor) and open the app. check ur voltage. 4200 is full, 3700 is empty.
[EVO 4G General] Dan330:
got the widget..

it is a little nutz..

show now.. 76% ... whichi is what is... me playing with it.

but the voltage.. has been flying around...

112mA up to 448mA.. and many points in between..

different each time I wake up the screen.
[EVO 4G General] dkdude36:
no thats the usage voltage. that is how much is being sucked. whats the number between 4200 and 3700 to the right if you hit battery history?
[EVO 4G General] Dan330:
3889mV

73%

328mA
[EVO 4G General] dkdude36:
so ya, you should be at like 30%. 3889mV is alot closer to 3700 (totally empty) than 4200 (totally full)
[EVO 4G General] Dan330:
ok.. well.. it s at 72% as of midnight.

I am going to play some video games "Dungen Hunter" before bed.. I will not put it on the charger.

see what happens by tomorrow morning..

if my alarm will not go off...

and if I will be late for work or not.. LOL
[EVO 4G General] dkdude36:
well, good luck. i just dropped 20% in an hour (from 50 to 30) after a day of heavy use. so the same may happen to u.
[EVO 4G General] Dan330:
played "Dungon Hunter" for about an Hour..

went to sleep at 1am... it was 49%

i am now in the office at 9am .. @21%

that is with it overclocked to 1036mhz with screen on; 422mhz off. (on demand)

with 2 hrs left and at 21% battery .. till 24 hrs without charge and some use.

I think it is good. :)
[EVO 4G General] jc8081:
Dan may I asked what u did to get this great battery life?
[EVO 4G General] Dan330:
not really sure... here is what I have

1. rooted

2. Myn's RLS5

3. Netarchy-Toastmod 4.3.2 kernel

4. Setcpu : profile for "screen off" = 422 - 128mhz ondemand

5. did the battery conditioning at beginning of this thread.

6. i had GPS, wifi, 3G = on

7. i also did the proxy patch for data speeds: http://xdaforums.com/showthread.php?t=922978

8. Myn's ROM also use adfree to block ads.

not sure what the last 2 does for battery... just wanted you to know.
[EVO 4G General] gpz1100:
Dan, does your phone spend most of its time in proximity of wifi? If so, that in itself will increase your battery life significantly.
[EVO 4G General] jc8081:
I'm kind of new i've never used a kernal only roms. Would that kernal work on miui? And can someone link me to how to install kernals?

I'm new to all this so I'm not very credible but I just wanted to throw this out there. No matter what you do if you want better battery life because you love your evo and can't keep your hands off of it like me then its way worth it to buy an extended battery. I did and now I could never go back to a stock size battery. You can go name brand or generic. I have both. EBay has the generic for good prices. Im not affiliated with eBay or any of its sellers. I actually bought my stuff from Amazon. Unbuttoned only cuz I don't have PayPal. Anyway just wanted to spread the news. Hope it helps.

as for some help for some.... PLZ shut off 4g network if ur not using it or even in a area that can. i kno when i get it i would have to drive 2 hours to the closest location to use it(SCREW THAT) so shutting that off will help. also kill the auto brightness and set it to a very low state. and bluetooth can be useless. also "Juice Defender" has helped my hero for a couple more hours.
[EVO 4G General] ILLFINGAZ:
WOW!!! This is by far the best information I have found on here. Tried it on 2/12/2011 and it has doubled my battery life.

I have no idea if this works or not but willing to try. I thought my Eris had a short battery until I switched to the Evo. I mean Damn, My kids psp will play for six hours.

I have started the process, charged all night, battery showed to be 100 percent charged, turn off for hour and charged so more. When I did the 2 minute turn on deal gauge only showed 94 percent charge. Don't know if this means anything or not. Turned Evo back off and charging again for last hour. Guess I will see.
