HTC EVO 4G Won't - Stopped Charging Battery Issue

Hey Guys,

Two nights ago I woke up to an EVO that was plugged in with a Cellet

extractable charging cord, as it is just about every night. But, the phone was

still showing that it was charging the battery, animation with lighting bolt,

at only 50% charged after about 6.5 hours of charging. Hmmm....

The latter after trying to charge in the coffee shop first with Cellet chord in the

wall then a portable 3500mah solar portable charger; the phone not seeming to

charge at or past 50% charged.

My EVO is rooted but still with the stock ROM and the gingerbread 2.3.3 OTA

update. The battery is a Seido 1750mah and SetCPU is at 245 - 998mhz. The

phone has only been rooted for a few weeks, but I don't see where rooting

would interfere with battery charging.

I've pulled the battery out, several times to no avail. Switched back to the

stock battery, same results. However, if the battery is less than 50% full

the phone will charge the battery to 25% or 50%, weird. If the battery is

at 75% or more full, the phone will top off the charge to a green LED at 100%,

sometimes. Sometimes it won't fully charge the battery. Weird.

I read different posts regarding poor USB chords so I pulled out the stock

micro USB to USB, a charge only chord I figured, and am trying to top

off the Seido battery, which it seems to be doing as it's now full green but

still charging as the animation shows the bolt in the battery and the LED

is still orange.

If put the batteries in the Seido wall charger, the thing the size of a deck

of cards, both batteries fully charge.

I also use Screen Off by Iwashi Soft. That app has worked pretty well with just

a little funkiness now and then. However, while plugged in, I hit the power

button, instead of the home button to turn on the home screen. The phone

wouldn't open to any screen nor would turn on or off. So I ended up

yanking the battery to turn it off then reinstalled battery and turned phone back

on. I don't know if that had any effect on the charging issue, but I took

the icon off the homescreen and am using the power button only, for now.

I don't think both batteries are faulty at the same time at this point. I

don't know if the screen off app caused some wake issue that interferes with

charging the battery.

I do know that when plugging in the phone to charge there's a bit of clunkiness

initially as the phone locks for a second before allowing use for screen or app

and that's always been the case since the gb update. Also, the LED doesn't

always turn green from amber when fully charged with the screen off until

you reboot or use the phone in some way while still plugged in. So there is

some kind of wake issue in the stock ROM. But the latter has never stopped

the battery from charging.

I do know that Plume, the twitter app, started acting clunky with not updating

in the background unless I opened the app at least once after a reboot. But

I don't know if the latter is a wake issue.

Battery still seems normal. Heavy normal use, lots of SMS, tweets, Pulse reading,

Dolphin browsing, I'll kill 50% or more of the battery in 4+ hours. Otherwise, the

phone mostly in standby with periodic email and twitter reads, the battery lasts

all day or more than 24 hours. But the latter rarely happens anymore because I'm

a user.

The battery just went full charge with the stock charging cable just now.

This morning, I woke up with a dead phone, auto shutoff even though it was

plugged in which I did after solitaire and before going to sleep; as a charging

test.

I don't know if it's the phone or the Cellet retractable cord or both that's

stopping the battery from fully charging normally and consistently. I'll need

to get another data-charge combo chord and do more testing; and a new ROM.

Any ideas anybody?
