So it's already been established that after the EVO charges fully to 100% it then stops receiving a charge and runs off the battery before charge cycling again. All the while displaying 100%.
Has any effort been put into changing the way this operates? Seems like it'd be nice to leave the phone on a charger and when you take it off, it would actually be at 100% and not at some arbitrary percentage between 90% and 100%.
It's better for the battery life.It's really good option if you ask me.

You mean make it so that the battery's status bar shows a realistic value once it stops taking a charge, even though it's still plugged in, right? Not actually changing the way it takes a charge. I'd be interested in seeing that happen.
Is that why when you unplug it, the first 5% or so disappear within minutes?

Yup. This is why when you charge overnight the battery plummets right after.

Don't leave it plugged it after it reaches 100%. Problem solved.

Valid point. Lol
There are some people who don't want to wake up in the middle of the night to unplug their phone. Like me.
annoying, but just unplug your phone when you do wake and plug it back in after about 10 seconds. let it finish fully charging while you get ready.
it's better for the battery though, case closed. Lenovo has been doing somehting similar w/ their laptops for years. It never charges the battery past like 97%, and when it does reach the top it stops charging until it falls below like 92 then recharges. HTC needs to loook out for the battery they already have enough flak from all of us for the last few years w/ every touch device they have had. We want more life, and they are giving it to us, just wish they could figure something out like lenovo, let it go down to mayeb 94 then charge up again perhaps.
it really isn't true, mine dumps 10% or so off the charger regardless of if it has been on the charger all night or 2 seconds after it turns green.
So I've done the:
1 charge to green
2 unplug
3 turn off
4 charge while turned off.....to green again.
And here are my honest results.
Boom........phone has 20% left after 16.5 hrs of moderate use (calling time total 1 hrs talk total, surf /post 1 hour total, load up 5 apps from the market, listen to audio clips on the speaker phone for almost an hour straight, podcast this morning for 30 min...and other randomness)
And still have 20% left. Going since 6:30 a to 10:30 p...........approximately 16 hrs equals 80% so about 3.2 hrs left to use before dead.
THIS EQUALS APPROX 19.2 HOURS OF MODERATE USE BEFORE RECHARGE NEEDED.
eat it Apple 4G . You can't even reliablly make calls let alone last that long without charging. My 3g never lasted that long. You still need a wall Apple we are truly mobile. If I was on the road I could (don't need to just yet) swap out for another battery.
I'm loving xda for all their brains helping me get the most out of this phone. Thanks to all.
Sent from my HTC EVO 4G using the XDA App.
The point here is that we shouldn't have to do the "charger circle jerk" to have 100% battery. I should be able to unplug it and have a full battery. Not 90%. I might need that 10% later on today, its accomplishing nothing sitting on my nightstand.
If the battery is toast after a year instead of a year and half, i don't care. I want a fully battery, not an almost full battery.

My phone used to do this, even after i followed all the little tips and tricks of playing hide and go seek with the charging cable and my phone.
Know how i solved it?
Bought one of those $10 Ebay 2 1500mAh TP2 Battery And Wall Charger bundles, now i dont use the OEM charger at all, the cable turned into a permanent USB cable on my comp and never sees the actual HTC charging unit it plugs into for AC power. I have 3 batteries and i rotate them in that little wall charger which actually charges them to 100%. Its also proven because if you take one of the batteries, put them in the phone and charge them until the green light comes on, supposedly to "100%" and then take the actual battery out and put it in the ebay wall charger, it will still charge for another 15-25 minutes. Charging it in the phone, as soon as i unplug, it almost instantly always drops to 90%... charging with the ebay wall charger, it will stay at 100% for a while before it falls off.
Below is the link to my thread which contains linkage, pics and info about the ebay bundle, others also claim the same issues and fixes in my thread. I mean for $10 bucks, does it really matter if it works for you or not? Its worth the shot and for me, it was a great investment.
Best of luck.

So I just got this battery hm around Wednesday or Thursday, and I have let it die down to around 10% or less and recharged it overnight several times and I still only see a slight difference in battery life. I am (I would say) a moderate user and I know some people say they get around 2 days on heavy use so I wonder what I'm doing wrong..? I ran the SU command to delete the battery.bin file to wipe the stats while it was fully charged, then let it run the whole day again only getting around 12 hrs (probably would have been shorter, but I have juicedefender running, and I was at work for 5 1/2 hrs of those 12) and then I stuck it on the charger at about 7:45 and then around 12 it was fully charged and I of course turned it off, then back on and it said it was around 80% so I let it charged to full, reset it again then when I turned it back on it said it was full. I took it off the charger and within minutes it dropped 1% every minute or 2 and now around 15 minutes later it's at 86% and I'm not even doing anything, just sitting here with the screen on and Skype is running. I've only drained it/fully charged it a few times maybe 3 or 4 should I just keep doing that or did I just get a crappy battery? It's better life than the stock, so I can't help but think that it's not crappy just not fully calibrated or "worn in" yet. Any help would be greatly appreciated!
I too have a cheapo extended battery from eBay, for the first week I hated it, but finally I actually just let the thing completely die to wear the phone shut down and wouldn't turn back on, then I recharged the battery completely in a standalone charger(also ebay), then put it back in the phone and used normally, charging and discharging and now I can't even dream of going back to the OEM battery, my battery life has much more than doubled. I use my phone like most here with CM7 up to date on nightlys and I'm happy as can be. I also like the ext back on the cheapos much better than the seidio flavor.
So you use the wall charger from eBay to charge it? I don't want to take my battery out to charge it though every night, let alone turn it off because I use it as an alarm clock :X. I've read a whole bunch of different ways of how to charge it in your phone and most people even one of the legitimate companies (Seido) who sells it, says that if you let it go an hr or 2 after the light turns green its good to go, but I don't believe it charges after the light turns green hence why the charging icon on the battery goes away. people may "think" it does but I honestly don't think it does and if anybody can prove otherwise I might have to buy the external charger :/
Yes get an external charger, Preferably 2 batteries and 1 external charger.
I just ordered a wall charger for like $15 I hope this works. I'll just charge my extended battery at night and use my other battery when the extended is charging
Sent from my Evo!
I used the external charger just once to "calibrate" the battery it seemed? Since then I've not taken the battery from the phone and just charged it with the phone charger(plugging it in) and I have noticed a huge change in run time.
How do you charge it though now that its calibrated? Do you just leave it on the charger for a few hrs after it hits green or do you have to turn the phone off and back on then stick it on the charger

Yeah, its been about a week and my battery still can't even hold a charge, even if it isn't fully charging. It dies quicker than my stock battery. I told the guy I bought it from, and he said he'd send me a new one so I'm back to the stock battery for now until I get this one next week :/

Oh right. So its okay to leave the phone on charge overnight. I think i'll just do that then and every month just drain battery and recharge fully !
I actually don't plug my phone into the charger. I bought some after-market batteries that are the same as the stock battery. I used to have 2 spares, but one was faulty, so I'm down to my main battery and the spare. I leave a battery on the charger until I need it, then stick the other one in the charger. I'd say they stay on the charger for up to 24 hours.

So you take each battery out of the Xperia Play and charge them ?
Yup. Once you take the battery out, wait about 30 seconds before putting it in so the battery usage gets wiped. Once you put the other battery in, boot up and you're good to go.
Depending on my usage, I usually just charge it over night, leaving it plugged in from when I go to bed, normally around midnight, to when I get up again at 7ish. I've never had any problems doing this, I am however a VERY high usage person, so a lot of the time I have to give it a top up in the middle of the day, before I go to work.
I usually charge up to 100% right before I go to bed and unplug it and reboot it. I've still got 99~100% in the morning.

Is it okay to charge the Xperia Play through a extension unit ?
I charge 1-2 times a day. Basically every night before bed I plug it in and it stays for about 6-7 hours, But the bad cell signal at work eats through my battery if I do a lot of texting or anything so by around 4 pm sometimes I plug in for an hour and top up (I'm usually around 25% at that point), or sometimes when I get home but know I'll be headed out I plug in for 1/2 hour or 45 min to get it up around 70-80% or so and I'm good till I get home, even if I play games and stuff or whatever else.

Yeah fair statement, I had thought about that. I wasn't sure if it was bad to say plug the phone in at 11pm until 7am (8 hours) charging whilst it being turned on? I assumed if it was going to be plugged in say for that long that you should turn it off.
I just plug it in - went to bed on 80% last night but fair enough I'd hardly used the phone all day (standby battery life is incredible)

So you stuck it on charge just to boost that extra 20% yeah? How come you didn't just leave it until it was low?
Should of asked if people would partially charge it or if they always ensure its fully charged.. Can't amend the poll now though.

Where did you hear that? Mines dropped to 14% before and I then turned it off and charged it and the battery still seems fine. Wasn't aware you could damage the battery if it got too low...

I have always charged with the phone on, all my phones since way back having an analogue Nokia mobile and never had any battery issues. Only time I have ever switched my phones off is if I was getting on a plane or the battery got really low and didn't want it to go completely flat.
Just plug it in whenever. Modern li-poly batteries doesn't have memory and charge cycle life is based on full charges.
Part charges actually increase life due to low % cycling

Agreed.
One thing to note is that you should never let it completely drain the battery, the phone will switch itself off once the battery reaches critical level then it needs a charge. I'd recommend charging it when it reaches 5-15%.
Also I'd never leave it charging over night it interrupts the cycle, if I have to charge it over night I set an alarm to go of after a few hours and unplug it.
i have 3 or 4 charges from different makes-and only htc charges the quickest. the worst is usb cable and car charger. but due to usage i need to charge twice a day

You are 100% right most modern phone battery’s don’t have memory any more so no need to worry about it, and no need to do full discharge and recharge cycles to maintain battery health, and if they do they normally tell you in warning labels or in instruction manuals, for example I recently bought a new shaver and it tells you to do a full discharge and then leave it on charge for at least 12 hours every 3 months to maintain battery life.

batteries have safety features built in so don't worry. What for you looks like 0-1% left - what android is showing you, might be actually 10-20% as seen internally by the battery.
Also, I have completely discharged my phone once, I simply left it at 1% and waited until it shut off. Then I charged to 100%. From then on, I charge whenever I want, phone is always ON.

Right, but do you know if this is actually the way to go with the Li-Po battery or are you, like me, just winging it?
When i first got my phone i let it run down till it asked for the charger, then left it on charge over night.
I did this for the first 3 or 4 times as i found this yields the longest battery life, since then i charge every 2 days regardless what percentage is left always over night though.
Going to leave it tonight & see if it will go till tomorrow night, its been off charge since 7am on Friday morning so far & is still on 46% a total of 39 hours so far.

You get two days on a charge? Are you a wizard? Although, having just got the phone (and possessing the patience of a 5 year old), I've done a lot of start-stop charging, which I suspect isn't optimal.
I'll try to refrain from trickle charging for a while, see how much difference it makes. Thanks.

I have noticed that the battery does drain in strange amounts.
I have my wifi & gps on constantly, my phone went for 2 days 5 hours & i received a text at which point the phone was at 34% battery.
The phone was put back in stand by & the phone went totally flat in the next 4 hours, this i find strange as over night in stand by it only uses 1 - 2%.
There is obviously a bug in the way the phone reports its battery state, by my reasoning this must be some 10 - 15% lower than what it is reporting.
It does seem to have some difficulties reading the battery level correctly. I've noted a couple of times that it shows a significantly higher charge level (+5-7%) after a reboot. Which is hardly likely to recharge the battery. (Unless I got me one of those perpetuum mobile, in which case, yay!)
Guys this issue is annoying me. My device is having some charging problems. I have measured the charging time for last two charges, and its taking 3 hours 40 mins for 10% to 100%, and 4 hours from 0% to 100%. Where most people are saying it takes around 3 hours, from a complete drain to full 100%.
So have any of you guys ever measured the actual time of charging? A lots of comments I see say around this or around that, or from 2 hours to 3 hours, well that's not what I need. If anyone has measured the time then please post here. I'm thinking about going to SC, but I don't wanna go there until I'm totally sure that there is a problem.
PS: I'm talking about Stock charger, (2A) plugged in AC power source. And device should be on, not off.

I don't know the math stuff but why don't you try calibrating the battery - worth trying !
Knowing that info is only half the truth. How the phone charges the battery and how much energy your phone uses during the charge matters too.

The time taken to charge is a pretty simple mathematical formula. But the rest of the calculation is complicated.
If you phone is on, how bright is the screen, is the display on or off, are you on wifi or network data, are you syncing email every 15 minutes or every hour, are you using the phone to send messages during charge, have you got gmail, dropbox, facebook, instagram, whatsapp, etc etc etc all doing a sync at regular intervals during the charge?
All of those things will use up some of the charge as its going in, so the charger is fighting against you.
I've been charging off usb at work and struggled to gain 20% in 8 hours because of my usage pattern.
Theoretical time for charge is about 1:30 hrs. Reality, start and ending charge should slow down (for safety), heat slow downs, plus usage of phone as spoken above I guess it could take up to 3 hrs.
It's not great to do a full charge regularly. I tend to keep mine between 40-90% for maximum life cycle of battery.
Perhaps try resetting battery stats? Try a different 2a charger?

Mine takes 2.5 hrs to charge from 10% to 100% with phone on using stock wall charger and cable (when charged continuosly with no activity on phone). It charged from 1% to 96% in 2.5 hrs with phone switched off (switched it on exactly after 2.5 hrs to check). But, usually i avoid charging my phones to full 100% (also always charge it when at 10%).

It charged from 1% to 96% in 2.5 hrs with phone switched off (switched it on exactly after 2.5 hrs to check). But, usually i avoid charging my phones to full 100% (also always charge it when at 10%).

Try with another note 2 charger first. The thing with these chargers is they will behave erratically when there is voltage fluctuation or if you use in a train and other cases. So go to SC and tell them its taking almost double time for me to get charged. They will replace the charger as well the cable. My cousin has the same problem with s3. He got it replaced by the SC.

Thanks Chaitanya. But the SC guys are so stupid here. First thing they do always are to take the phone in their custody and deal with it badly. Still I will ask them to replace the charger and check.
Some of us have noted that if you let the screen time out and not manually shut screen off after connecting the charger. ..The charging is faster. . If you manually shut off the screen. .. The charging is slow.... It is weird but don't know why. .it definitely is happening

Mine takes about 3 hours to charge fully from 15 %

Op: I said theoretical it will take 1:30.. Realistically it should slow down during stages due to safety reasons.
Mine took probably 3 hours the other day I ran it down, but this was combination of using 1a and 2a charger.
I think on the note 2 it doesn't ramp up power till it gets to 20-30%. Took a while to get there from 2%. If only battery widget was working on the note 2..then I could confirm.

Are you using the charger that came with Note2 ? I was using my old blackberry charger and it took for ever to charge the phone.
The output of the Note2's charger is more than twice the output of my blackberry charger.
^ Yeah, of course I am using the stock charger that came with Note 2! I'd not create this topic if I had used another charger.
Anyway, after a long week in Service Center now my phone is back, they provided me a new charging adapter (not the cable) and I was very happy because I thought everything will be smooth and like before but guess what? No improvement. It's still taking long! I just measured it for 30 mins exactly, it went from 70 to 83%, i.e 13%, where it should be 24% as stated in this thread,

Now I am really angry. I will try with another Note 2 USB cable first, if that fails, there is something wrong with the device, I guess?

I really don't think it's your device or your battery for that matter. I have a question as well (sorry to hijack...). When you were charging it for 30 mins, were you using it? Was the screen off or the phone totally turned off? I noticed one night that I had an email notification and the phone did not charge because the notification LED was on all night while I slept and it was plugged into my 1A Samsung charger from my original Note. I have yet to check if the charging disconnects itself if the LED comes on. I don't even know if the phone charges at all if the screen is on either. Can anyone confirm? I guess I'll try it out tonight! The battery last forever I got to admit, perhaps most of the time I'm slow charging it at 1A max with the original Note's charger? I guess it does the battery some good
Thanks a bunch!
No pal I am not using the device while charging (because I am testing and measuring the times, that's why I restrain myself from touching it), and it's on, not off.
Anyway, yesterday I went to a friend's home and found he has a Samsung ACE and has same USB port like Note's and I was carrying the charging adapter, so I took that Ace's cable and plugged in to my Note's adapter and let it charge for an hour, and I was amazed and happy to see that it increased 38% in 60 mins. Well this tells me that the USB cable of my Note 2 is gone to heaven.
And oh, if you charge and use the device at the same time it will charge pretty fast even then too. I can confirm this when I first got the device, always was using it and charging, and I was surprised to even then how fast it was charging.
I (and many other users) have similar problems with Galaxy S3. I've made an app that shows the actual charging current: http://forum.xda-developers.com/showthread.php?t=2076078
I'm not sure if it works on the Note 2, but it is worth a try.
Please check if your device is charging at the optimal charging current (I think it is 2000mA for the Note 2 charger, instead of 1000mA as pointed in the SGS3 thread).
