Wow. That's a good idea to automate the topping off in the morning. I might give that a try.
and technically how does this resolve the issue? I would love to know how having admin rights to your phone suddently corrects charging woes.
haha, this is what guys with diesels do in the cold climates when they have block heaters.
yeah, i'd have to agree with this too. i was obsessing over the battery life for quite a while after getting this phone and it was really bothering me. i finally removed every app that would show me the actual percentage. now all i use is the battery bar at the top of my screen.
i'm sure the battery is draining at the same speed that it always has but when you are just seeing the bar at the top, it doesn't "appear" to drain as quickly. in short, i am much happier with my EVO now
Still, there's a role for the battery-percentage app, such as telling me when an app is using an insane amount of power. That's how I noticed something was wrong with Stitcher after the Froyo upgrade. Maybe iheartRadio is supposed to drop the battery 10% in 30 minutes over 3G, but not Stitcher (which didn't in Froyo).
Agreed.... If any thing you get a quick drop of 5 - 10% and then the drain is slow any way. I throw my phone on the charger when I go to bed and take it off after I go down and start the coffee.... I use to obsess about the battery life but the more you ignore it the better you are.
Even with Froyo at first it seemed like worse battery life but over the last few days (as I have stopped obsessing about the battery life) just using the phone like normal and checking battery life when I go to bed it's easily 10x better than when I checked it every 20 minutes or so....
I am basically back to 16 hours with 25 - 40% remaining depending on how hard or light I am on it....
I agree to a point... I have a few battery charting Apps on my EVO but as long as my phone last me from the start of my day until I go to bed there is no reason to check those Apps Hourly or even daily..... If I pull my phone off the charger at 7:30 in the morning and at lunch I am at 30% remaining... Yeah, I am going to plot and see what is eating battery life.... But if you pull it off the charger and you get what you expect out of the battery for your use then whats the point???
I did have a program get hung but it never pointed to a specific program. it would just say some thing was at 100% and no name in the block or graph.. hard rest cleared it up.... But because of those graphs and Apps I was able to notice SOMETHING was eating it up (I went from 16 hours a day to less than 6 because some thing got hung)
Other than that I typically check battery life/performance each night before I plug it up and that is it.....
Pull the Evo off the charger RIGHT when it hits 100%.
Unplugging the phone when the battery hits 100% won't change a thing. Look at it logically:
The reason for the sudden drop when you unplug the battery charger has been well documented: Once the battery hits 100%, the charging circuitry in the phone shuts off, and the phone starts running off the battery. There's no "trickle charge" mode on the Evo. (It will start charging the battery again if the charge drops below a certain point.) But the battery indicator stays at 100% as long as the phone is plugged in.
So what's really happening is that the battery is discharging while the phone sleeps, but the indicator doesn't show that. But once you unplug, the indicator catches up with the actual battery level pretty quickly. So while it appears the battery drops from 100% to 90%, the battery was really at 90% all along.
So if you leave your phone on the charger once the battery is fully charged, the phone runs off the battery, and the charge gradually drops.
If you take your phone off the charger once the battery is fully charged, the phone runs off the battery, and the charge gradually drops.
No difference at all.
How to fix it? As others have suggested, use an external charger. The $10 charger + 2 battery deal from ebay is hard to beat. But I find repeatedly removing and replacing the battery a nuisance, and I want my phone ON at night, so I can see missed calls, get SMS, etc., so other options include:
When you unplug the phone, turn the screen on, wait a few minutes, then plug it back in and let it charge back up to 100%.
Or, if you're rooted, install setcpu 2.2. This will dramatically reduce the battery usage when the screen is off, so the battery won't drop as rapidly after it reaches full charge.
Or, don't worry about it. Just top off the charge at some point during the day.

How is this no difference at all? You said it yourself, the battery was really at 90%. So isn't it when you remove the charger once it turns green it's truly 100%? That's kind of the whole point in topping off.
Exactly, there IS a difference - 100% and 90& are two different things, and frankly I'd rather start the day at 100 rather than 90.
But this isn't a battery widget problem - its' a real problem (that we've all seen). If the drop was 1 or 2 percent, then yes I'd agree with you - get over it and move on. But 10% is meaningful. Have you ever seen another consumer electronics device that can't charge its battery properly?? I sure haven't and I've owned an awful lot of them.
Look, we're not talking about a new technology like 4G, nor are we dealing with a complex problem that's new to smartphones. Being able to charge a battery correctly is a problem that's already been solved (50 years ago?) - and frankly there's no excuse for screwing this up. I would encourage anyone who is bothered by this (and I'm not sure how you couldn't be - even if only a little) to get in Sprint's and/or HTC's ear about this.

It's not a screw up.
The Nexus One does the same thing. So do other HTC phones.
The reason is, continuously trickle charging batteries has been proven to shorten the overall life of the battery. If you are really anal enough to have a problem with 10% battery + or -, then you need to either take some of the suggestions here, or have a method to add 10% to the battery sometime during its discharge.
You might not like how its been engineered, but it's not a screw up. I suggest either what I've mentioned previously or returning the phone and getting a something that's not HTC branded.
Is being annoyed by a loss of 10% really being anal? Really? If you're EVO came with a 1350mAh battery instead of a 1500 like advertised would you really not care?
I've owned lots of HTC phones and have never seen this before, though admittedly I've not owned the N1. If you've had experience with it though, then I'll take you at your word.
I have no in-depth knowledge of battery technology by any means, and therefore I cannot refute what you said about trickle charging being bad for the overall life of the battery. I guess I'm just skeptical. HTC has a track record of sloppiness, and when they do something different like this I tend to assume it's a screw-up until proven otherwise. (screw-up or not, I still stand by my statement that it's not "normal") If all future smartphones start exhibiting this type of charging behavior, then I'll believe it.
How do you know your percentage isn't misrepresented and you are getting not the 1500mAh?
What if they just tricked battery percentage to go down from 100 evenly to not alarm you but it was still the same battery capacity? Would you be OK with that?
Well first of all, I do question the rated capacity of most batteries out there - especially the aftermarket ones. However, the battery widgets take their data from an API built into Android itself. I guess what you're suggesting is that HTC modified that code to bring back a skewed (and skewed in a bad way) result? Not likely.
But as Crackbone and many others have stated, this is not a "perception" problem. There is a real difference here with how the Evo (and apparently other HTC devices?) charges as compared to other smartphones. Rather than maintain the battery at 100% by trickle charging, it's stopping when the battery hits 100 and then kicking in later to cycle it as necessary.
I wish there was a lil polymore battery for phones, you would get a week at least on one charge and they are lighter..

You misinterpreted what I wrote. I was not suggesting HTC had done that...I was suggesting what if they did that to calm your fears?
I suggest you do some reading over at Battery University... Your battery does not like 100% charge.
Charging lithium-ion batteries
I have been plugging my phone in at night. Then in the morning I plug it into the car charger on the way to work. By the time I get there 20 minutes later, I am good to go at 100% battery charge.
I do agree this is annoying, though.
I do agree this is annoying, though.
i've seen this topic posted in both the incredible forum and the evo forum. but the nexus one doesnt have this problem. at least mine never has done it.
on the nexus, the green light turns on at 90%. this is by design and done on purpose. green light does not mean 100% charge. you still have another 10% to go.
i think everyone is seeing the light tunr green and thinks they are full.
also for those who say that at 100% the battery charge does not trickle and uses the battery, that's not correct. the phone will run off the charger all night long and the battery will not deplete. see my logcat below:
