If you guys want great battery life, charge your battery in a TP2

That's right... For some stupid reason, our phones don't detect when the battery is ACTUALLY full. Getting annoyed with the having to charge my phone twice a day, I stuck my battery in my old Touch Pro 2 (left it powered off) and plugged it in... It took about 5 hours for it to fully charge and I let it sit for another hour.
I took it off the charger at 11AM... It is now 11PM and I'm at 68% and I've been doing more browsing and downloading than usual. Previously, I would have hit 20% by now and had to plug in the charger.
Once you charge the battery in this manner once, it should be fine from there because the cells have been fully charged for the first time. As long as you don't drain the device completely, you shouldn't run into battery issues.

Ordered a multi-function battery charge and two aftermarket TP2 "1500mAh" batteries from eBay, all for $11, hopefully they're good

I've been pounding the hell out of this thing today... I've racked up 8 hours of "active" usage... so actually I've used my phone more than normal.
The first clue for me was the fact that my battery didn't drop from 100% to 90% in five minutes like it was before... It would usually drop to 80 within an hour, even on standby...
It was at 92% when I got to work at noon.

Unreal, I never thought I would search ebay for a phone with a BAD esn

What I think is unreal is that our 2010 devices can't do something other devices have been able to do since 2006... AT LEAST 2006...

I'm running fresh .3 and I've had the phone unplugged for 1d 0h 15m and still have 30% left... so I don't have an issue with the battery at all.

I have an IPAQ Pocket PC from 2002 that detects and charges its lithium battery just fine!

I have two of these chargers and 4 batteries. I keep two at work and two at home.
These chargers top the battery completely off. I can take a battery that is "fully charged" in the phone and put it in the charger and it will still need 20-30 minutes of charging. The batteries off the charger will stay at 100% for up to 20 minutes, the ones charged in the phone plunge within 1 minute for me.

I really hope this issue can be fixed with a software update. Charging once a day is one thing, but having to take the cover off, battery out and reboot every morning is not acceptable. Not to mention that I rely on my phone while it is charging for emergency calls.

AFAIK it affects all HTC Android devices. HTC is lazy. Anyway I even put my old TP battery which hasn't been charged for at least 6 months in and charged it with the TP. It appears the first 5% is dead but it is still kicking ass and taking names over the charge I get from the evo.

Your battery was probably charged to capacity before they sold you the phone. Once a lithium ion battery has been charged to 100% it maintains its charge unless you screw it up by running it down to empty a few times. The problem is that for whatever reason HTC didn't see fit to charge all batteries to their max first even full well knowing that they won't get conditioned properly by the phone.

I did too, but think mine is defective. The batteries are pretty good for backup purposes and do their job. My wall charger sucked though. I had a Droid Eris hooked up via USB and a battery on the charger. After about an hour and a half, the Eris charged fine, but the battery was like at 30%.
Now the deal breaker is when I got home. I tried to charge a battery and my EVO via USB. When ever I hooked up the USB my phone litterally lagged almost would freeze to a point. I removed the USB cable and phone worked fine. So in all my charger sucked and can charge the battery but really slow.
I ended up just charging the batteries with the OEM charger and EVO turned off.

Yes, but an HTC Windows Mobile device, not Android.

I think OP is talking about the TP2 OEM battery, not some knock off that you buy off ebay. FYI there are tons of battery for TP2, so it would have been better if the OP can tell us exactly which one he got. Check out batteryboss for comparsion:

Could there potentially be a software fix to make the evo handle battery management better, like the tp2?

Actually i was talking about putting your evo battery IN a touch pro 2 in order to charge all the cells.

So this is the reason why the EVO appears to be charging its battery so fast. I plugged it in, and it takes less than an hour to start beeping "I'm full."
......Because it's not really full.
That would explain why I was about to sleep, the EVO was charged, and I got an email, so it kept beeping every 10 minutes or so. which was annoying. I had to unplug it so I could sleep. I slept only 7 hours, and I heard the phone on the little table beeping again like crazy in the morning. I checked what it wanted, and it was the super warning that the battery was about to die.
No use at all in 7 hours, and the battery went from "fully" charged to almost ZERO.
I was almost crying of laughter. I just thought what a piece of junk. Hopefully I'm wrong.

Now, let's watch the soccer game, let's see how the USA does.

Battery Power Drops from 100% to 90% in about 3 mins?

Has anyone else seen this? From 100 to 90% the power just drops almost instantaneously but after 90% its normal.

Already been brought up, a lot.
Apparently when your phone charges up it stops once it reaches ~100% and begins discharging, even though it is still on the charger. People will turn their phone off after a full charge and charge for an additional 20min to an hour before they get another green LED. People have reported much longer battery life when doing this, but it is a pain in the ass.

Ahh interesting. I thought I was running into an old winmo rom flashing issue where if you flashed under 50% battery life you could never charge the device above that point.

Yea it sucks but it works... I just ordered an external battery charger since I have 2 batteries now so I don't have to do this anymore

Hmm i tried and it acted the same way.

Apparently the HTC models act like older phones did back in the day. What HTC needs to do is put something on the phone face itself when new that says "CHARGE FOR 4 HOURS BEFORE INITIAL POWER ON FOR MAXIMUM BATTERY LIFE."
Once you do this once you dont have to keep doing it. I also powered on my phone the minute I got it and activated it without charging it first and I was seeing this issue until I did a power off charge. The phone runs from 6am to 11pm without an additional charge cycle in the day and that is a huge improvement for me. I was charging the phone twice to three times daily.

How long does it take to fully charge on average?

I just got my phone and purposely used as much stuff to kill the battery as fast as I could. I didn't expect it to take so long to charge, it is like barely half way after an hour +.

For me like 3 hours to 3.5 total...

Is it that necessary to let my phone full charge before taking it off the charger and messing with it.
It's so awesome and I am just sitting here looking at it.

Yeah, about 3-3.5 hours for full charge from about 25%. Play away with it plugged in and enjoy!

Aren't you supposed to allow it to fully charged for optimal battery life? Like breaking in the battery?

I suggest letting it get a full charge before taking it off the charger, but hell, play with the damned thing while its on the charger, its an awesome device.

It also depends on if its plugged in via USB to a PC or via the included AC adapter. PC Im sure takes longer. I just plug it into my PC every night via USB and its fully charges when I get up. I think the charge time is prolly 4 hours or so.
Atleast this device charges when plugged into a USB port on a PC. There are some phones where the USB does not give enough juice to even charge. I have a Touch Pro 2 that I use for work and it wont charge when connected to a PC via USB as it states its not enough power to charge it and run it at the same time. Lame.
WinMo FTL. Android FTW!

3 Hours from 0-100% via ac adapter

I just noticed a flaw in the charging cycle last night. I put my phone on the charger when I went to bed. Halfway thru my sleep I heard the beep denoting that it was fully charged, showing that stupid message to un-plug it. In the morning, it was still plugged in, but I had 50% battery and the charging icon was not lit saying that it was plugged in. WTF, I want it to stay FLOAT charging while it is plugged in, not waking up to a half dead battery in the morning.

Yet Another Battery Tip

Well... I completely stopped charging my phone with the wall charger and I am now just using either my car charger or USB and i've noticed my phone over the last two days has probably doubled in being able to hold a charge. Today I made approximately 2 or 3 30 minute - 1 hour calls, used the internet approximately 20 times for about 5 minutes each time and used SNESnoid for approximately 1 hour straight and my battery was at 40% after a 10 hour work day, not too shabby. Not to mention I also don't get that annoying 10% drop within 10 minutes of unplugging the phone anymore
I've seen a ton of other battery tip's but I've yet to see any actually say stop using a wall charger all together. Here's to hoping this helps someone

Lol thanks for the tip. I highly doubt this is anymore then a placebo but good luck to whoever tries it. Not calling you OP I am just finding it hard to believe.
Furthermore, have you tried reseting your battery stats. I mean the initial 100-90 percent drop you are calling to quick sounds like its the fault of bad battery stats. If you need a link to how to reset your battery PM me only because I might not check back to this post lol.

Hmmm... I don't think that USB/Wall would actually make a overall difference in battery life but it could be that it doesn't "idle the charging" when you hit close to a full charge. So you're probably just getting the extra 5-10% that you mentioned.

I know for a fact im getting the initial 10% but I looked at my battery today at 12:40 tonight before leaving work thinking "ahh crap I haven't charged it it's got to be at, at least 5-15% and nope, it was exactly 39%, I was amazed. Talked to a girl for about 40 minutes on my drive home, talked to another friend for 5 and battery dropped to 35%

I've noticed this as well. Days that I've only used my moto car charger, the battery (even the cheap ebay ones) seem to hold the charge better, which I thought was strange, because you would think it would be a worse -maybe equal- change.

Charges more slowly and fills up more?

That's my theory

This is the case with most batteries, and I thought it was common knowledge with Li-ion. The lower the current you charge with, the better the charge.
Using the higher amperage wall charger lets you hit the voltage peak quicker but, the topping charge will take longer. A lot of car chargers are just as high amperage as wall chargers.
Other things you can do to try maintain the capacity of the battery over the course of its life:
-NEVER let it get hot (whether from heavy usage or keeping it in a hot car or the sun)
-never deep cycle (totally kill the battery)
-try to keep it between 40 - 60% charge for most of its life (Li-ion batteries do not like being at full charge or no charge)
Doing any of these things once will not destroy the battery, but by the 500th charge cycle, you can bet your ass it will.

Sounds like my kind of job! Seriously, I use USB (through a laptop) and car chargers almost exclusively and I have no real complaints about battery life. And by that I mean it gets me through the day, which is all I've come to expect from phones for the past few years. But I did happen to use a wall charger last night, and I have JuicePlotter active, so I did some checking.
Comparing my last overnight charge using my laptop's USB to last night's charge through a wall adapter, I found that the charging was actually faster through the laptop. I see that the charge tends to drop off as it approaches 100%, so I took pairs of points from uniform sections of each plot for my comparison:
Laptop USB:
44% to 82% in 41 minutes = 0.927% / min
Wall:
63% to 91% in 37 minutes = 0.757% / min

Hah, yeah my job is pretty amazing sometimes but I have def quit using the wall charger (unless I absolutely have nothing else around)
As far as for droiddev... this is my first phone where charging it from different devices gives me different results. I don't see where it would be common sense, Li-ion batteries are not supposed to not have these memory leak/hold issues like past batteries. A charge is a charge to li-ion batteries, but not in this case.

Not sure what you mean, but you will get the most life out of your battery by charging it short spurts at a time over USB. Read the article I linked to and you will see what I mean, but you can get the best charge into your battery by slowly ramping up in steps with a low current charger.

Charging while in use

If I have the screen on while plugged in, my battery % continues to drop and the device itself feels kind of hot. Could I have a problem or is this normal?
My battery life has also not been so great.

Mine doesn't it keeps going up, though I haven't tried playing games. It does depend on what you are doing with the device, if you are running applications that max out the processor it will possibly drop.
The GSII would drain while plugged in if the screen was on. You would see a noticeable drain while using GPS and Music and driving. The only way to make it work was to turn the screen off on the device, the GSIII has a better charging chip in it, and it isn't limited to 650maH (from what I can tell since it is charging when using GPS)

I noticed it while using a usb car cigarette adapter as well as a usb port on my laptop. the car adapter is a 2 amp charger capable of charging a tablet. I will see how it performs with the oem wall charger.

Yeah I was charging my phone earlier using a car was adapter with the oem micro usb cable and they phone got very hot.
What do you guys think? Is this a cause for concern? Do I need to buy a manufacturer approved adapter?

Is it safe to leave the phone plugged in overnight? I usually charge the phone when I go to bed, but I've the this might damage some batteries.

I'm curious about this myself....I'm leaning towards not leaving mine plugged all night. I 2 have done this in the past with other phones and can't be certain but maybe this is a rEason I had horrible batt life despite efforts to Better it. So I'm gonna stick with charging/topping off when I can. Gonna start just charging when I wake up while I'm getting ready for work. I did notice that when battery is completely charged a message comes up telling u so and to unplug. So I'm gonna follow directions haha.

All modern smartphones have chips that control power, and cycle charging appropriately to not abuse the battery. Many phones monitor the temp of the battery and such to ensure a good and safe charge. You can leave it plugged in overnight just fine..

It definitely doesn't like 3rd party adapters. I'm hoping it will at least accept the tab adapter with samsung's cable so that I can charge it at work without buying a dozen chargers, but...
(One charger I used is understandable - turns out its only 300ma. Whoops! But using full 1A chargers wasn't helping either, it went up maybe 1% every 15 mins. The stock charger ran it up fast enough that it was charged from 70% in under an hour.)

I use SetCPU and have a setting to reduce the clock when it exceeds a temperate parameter. You could also set a max clock for when it is plugged into a USB (Computer/Car charger). That could help it stay cooler and charge faster while not plugged into the wall.
I charged from empty to full this morning when plugged into the wall in about 3 hours. I haven't tested on my computer yet.

I went through this when I first got my Evo 4G. I did not realize at the time that the 500mA charger I was using with my Blackberry Storm (horrible device) would not charge my Evo while doing anything power intensive (like using GPS) and I quickly drained it on a car trip.
I went on Amazon and bought a $20 Schosche iPad charger that claimed to provide 2.1A which should be plenty. On that charger the phone would charge while using GPS but very, very slowly.
After some more research I found that some chargers caused the phone to switch into "USB" charging mode and others would switch it to "AC" mode which would draw much more power and charge faster.
This is the charger I ended up with and it works great:

My Evo charges just as fast as it does on the OEM wall charger. I don't have my SIII yet (thanks Verizon for being the LAST in the US to ship them out...) so I can't yet say if this holds true for the SIII but I assume it will. At $1.22 it's not much of a gamble.
