Overcharging the battery?

Is it possible to overcharge the battery? I ask because when I first got the phone and fully charged it, it would stay on 100% for at least a couple hours (using circle battery widget which reads in increments of 1%) but one night I fell asleep with it plugged into the charger and when I got up it still read 100% but as soon as I unplugged it it went immediately to 99%. I have not yet been able to get it to read 100% unless its connected to the charger. Think I could get the batt replaced under warranty since its only 2-3 weeks old?

Your battery is fine, it is set up so that it will not overcharge. I tried searching for an article that explained how the system is set up but couldnt find it.

I'll look in to that. But what about the battery immediately dropping to 99% when I take it off the charger?
sent from my Motorola Atrix 2 via Tapatalk

Every android phone I've had has dropped like that as soon as I've taken it off charge, nothing to really worry about.

They do a think called power cycling. It will charge it to 100% then shut off then once it goes back down it will charge it to 100% again. Ill try to find the article. Your battery is fine.

Weird. My SE Xperia X10 didn't do that, it would stay at 100% for at least an hour. I recalibrated my battery a couple days ago, thinking it would remedy this "problem" and after it died on me I charged it back to 100% and took it off the charger at 10pm, set my alarm on it and let it sit overnight. After pressing snooze on my phone 3 times and finally getting up at 630am it still was at 100%! So it's strange to me that this drops to 99% immediately but if it's happening to everyone else I won't worry too much.

Well if I were to judge off that, mine stays at 100% for hours......im going on 7hrs right now. But I use battery circle widget which reads in 1% increments......as soon as my phone comes off the charger it goes straight to 99%......it didnt do that before.

Battery Charging & calibration query
What difference does it make if you charge from empty to 100% in switched off stage and the same in on state? Which is better? How should we calibrate the battery and how often using which app for unrooted MB865 Asia retail? Also if phone dies (switches off) constantly due to insufficient charge does it harm the battery in terms of cells getting destroyed gradually & finally does switching off or switching on the phone while charging have any effect issue on phone or the battery?? Thanks in advance for inputs for all queries.

Battery issues! Running out of ideas. Can someone help? (SOLVED)

I can't seem to figure out whats wrong with my phone. I have a draining issue with my battery and i don't know if my battery indicator is not accurate. I used odin and went back to stock on a full indicated battery. Then I flashed VB and adrenaline shots 1.4-1 and camera tweak and scrolling mod and booted the phone and let set for 10 minutes before I reloaded all my apps. My battery was indicating it was at 100% ok so i unplugged the battery and wham it dropped to 79% plugged it back in and it started charged from where it left off at 79%. After a few min and the phone goes to sleep mode and indicates 100% i unplug the phone and it charged from where it left off at 79%. So i kept unplugging it and plugging it back in every few minutes till i got to 100%. So sounds ok now but i had to reboot my system and wham again down to 79% and even with the uv settings my battery drains fast. I tried calibrating the battery and also charged it with the phone being off and no results. All I want is a full charge as I work long shifts lol. thanks and i hope this is understandable the way i tried to describe it.
Also Thanks to the devs on here who dedicate their time to making this device do what it was meant to do..

Try letting the phone die completely. After about ten minutes power it back on then let it die completely again. Leave it off for an hour then plug into wall charger. Let it charge to 100% while off. After it hits 100% unplug it and leave it sit for an hour while off. Then turn it on and use normally.

Not to contradict hechoen - but take note that Samsung recommends against completely discharging your battery in the manual for the phone.

+1 (edit: on previous calibration routing)
also you may try to "jump start" MAX17042 (fuel gauge) chip... when your phone at 100% on a charger (verify this by looking at battery voltage - OS Monitor / Misc tab. or other similar apps) - voltage should be around 4.15 - 4.2V. When you disconnect charger - what would be the voltage then? If around 4.0V then may be your battery is going south.
To "jump start" FG - turn off the phone, pull battery out and wait for 5 - 10 min. - just to be sure internal circuits got completely discharged.
When you install battery, FG chip will use "average" model for new lipo... see if it makes difference.

Yeah I've heard that this kind of batteries last longer if charged continuously (short and often charges) instead of full charges after letting it die. Something about battery cycles or some.
I'd recommend fully charging and battery calibration from market. Also, reflash rom but not tweaks yet, and see how it behaves. Then install tweaks/mods and see if the battery continues to decrease rapidly. If it does, get an app for battery info, check its health.. Your battery might be dying for good.

Google has also debunked the battery calibration myth. There is a thread about it in the General Section with a link to the article.
To add to the recommendations...
Check how often your phone is set to sync. Big battery drainer. Auto starting apps. And display brightness.

if all fails you could try to reflash and see if that fixes it

Wait, I didn't say battery calibration is going to make your battery last longer. It doesn't do that.
But it's a fact that after installing a rom a battery calibration is needed. Normally, developers code their install scripts to perform a battery calibration when installing the rom, so this is not needed afterwards, I still do it anyways when charging the first time to 100%.
I for one had the issue for the first time when installing a rom (don't remember which one) and after rebooting or shutting down the phone, the battery would go from >90% to <20% for no reason at all. Someone here at XDA suggested battery calibration app (or, manually at CWM/advanced, clear battery stats) and the issue was gone. Maybe the rom is misreading battery data and that could cause this kind of issues... which a battery calibration would fix it.
Just saying.. if there's an option for it in CWM, then chances are it is needed for some reason!

Indeed. It's on our wiki, too, under the batterystats.bin Buzz Word entry.

So i think I needed to do a factory reset. I re flashed vahnilla black and then did a factory reset in the rom. Before I re flashed the rom I
had 60% as soon I restarted the phone on the freshly flashed rom it dropped to 1% then I did a factory restart within the rom and when I rebooted the battery indicated 20% and I am in 16% charge now, only went down 4% within the last 6 hours. So I will run it till it dies tonight and charge it with the phone off to see the results tomorrow.
Thanks Raver for the help in this matter. Will keep everyone posted on the end results.

No contradiction at all. You shouldn't fully discharge all the time. But once in a while it's actually good for the battery. Especially lithium ion. Take a look at this. For those of you who don't like to read that much just skip to the bottom.

I fully charged my battery last night while it being off and let it sit for a hour before turning it on. Well great seemed to now indicate it's fully charged after a hour I threw on adrenaline shots 14-1 with camera and scrolling mod. Let it air for 30min went into recoveryand fix perms. When I rebooted the phone the battery dropped again from 80 to 60 and then went back up to 75. Then I rebooted again it dropped to 25% and then I rebooted again and now it indicates 59% I believe this battery is heading south. What do you guys think?

How old is the battery. If it is a quality battery it should take between 500 and 900 recharges. Do you own a volt meter?
Also calibrating your battery should be done occasionally. Not to somehow make your battery last longer, but to clear out the old data and use new data to show your batteries usage. Just like resetting the computer in your car that shows average MPG. Fresh input will give you a better idea of what your car is getting today and same goes for your battery stats.

I have calibrated the battery. Everything seems to of been working fine until I added adrenaline shots. Once I rebooted after installing adrenaline shots my battery started acting up again. I pulled the battery out for 10 min and popped back in and now I'm indicating 56% after 4 hours of heavy use with wifi on. :/

Is this a factory battery? Or a aftermarket ebay/amazon battery?
Im sure people will disagree but some of those aftermarket batteries are not the greatest quality.
Do you live in a town that had a battery store, like the interstate battery shop or something of the likes? Most of those places can do a brief diagnostic of the battery and tell you if it is bad. Or if you have a volt meter fully charge it and test it that way.
It really sounds like the battery is being stupid. There should not be any reason installing A.S. could cause a instant battery drain. If that were the case your phone would be so hot you could not hold it. Because draining that much juice in that little of time would indicate you have a short or something of that nature.

Serious Battery Problem !

There is an unusual ..battery problem is going on wid my fit!

That option is not really helpful..! Either Calibration is totally messed up....or battery is dead!

Battery may have been swollen or dead
Same happened to me too, you have to buy a new battery now....my battery had swollen 2x its size , It charged from 0-100 in 5minutes and then discharged in 2minutes.....It had swollen and died.
I think the same happened with you , either it has swollen or it died.
Battery Swells when due to over charging and high temprature!
Hope I helped you...

mine too died buy a new one

[Q] Huge Battery Drain on Reboot

Hello Folks,
I m facing a wierd prob on my device from last 3 days and its about my battery. its not about how frequently my battery is Draining. When i charged my Mobile fully to 100% and Reboot the device , after reboot the Battery comes to 93%. same when my device was on 35% and after reboot it came down to 3% WTF.
I thought its battery callibaration prob. i was on DDLF2 when this prob occured so i made Full Flash using XXKPE--> XXKPQ. But still prob Persisted. Then i used a app Called Battery Callibration From market By "Nema" and follow the Procedures as mentioned by app to callibrate my battery. bt still the prob persist.
one more thing , after doing 100% charge the app showed battery has 4185 mV of charge and After the reboot the perc. came down to 93% then app showed the battery still had 4122 mV but with 93%.
im currently on Stock XXKPQ

I'm having this problem aswell. Don't you worry, its quite offten appear after flashing. Use your phone as usual ant and your battery stats get normal after couple weeks. Don't do any calibrations, android does it by himself.

Thanks mate , i will try it and post feedback after a week

Charge to 100%, drain to 5-10%, charge to 100%. Repeat a few times. This is battery calibration, the app does not work.

I feel battery calibration is most rediculous method that android users have to do. A dumb nokia 3310 can show us accurate battery indicator even if we reboot it 100 times.
Google developers really have to concentrate on this battery part.

It is normal for a newly flashed ROM. I always had 20% drain after reboot after new flashes. It's normal if:
1. Newly flashed rom - let the android calibrates itself.
2. Fully charged battery which was left attached to the power source for sometime. Battery discharges itself quietly despite it showing 100%.

Probably you need a new battery...there's a limit to how many charges...happened to me, my battery was no more than 12 months old...try this..charge with the phone on till 100%, then shut down the phone, charge with phone off till 100%..switch on the phone and if you do not get 100%, repeat the process until you have 100%...

me too, when my phone fully recharge (showing 100%),I reboot it. after I reboot it shows 92%

Charging time

Hello, I have bought rooted htc sensation and am very upset with it's charging time, it takes about one hour to charge 10% of battery. Example today I started charging it at 7:05 when it had 49%of battery. Now it's 11:06 and battery shows 88%. I know it's not normal. Is there any way how to fix it, or maybe test my phone somehow? Should new battery solve this problem?

Try deleting battery stats in recovery, this can lead to misreading. Also, usually the battery is higher than the percentage shown, just reboot your phone and you'll see how much battery is left (one time it showed me 2% when I actually had 45%, but that's because I put my phone in a -20C freezer).

Try the 'battery calibration' app on the play store, I believe it can do this. But keep in mind that the battery an lose it's calibration with time, and even if uncalibrated, it will last about the same (although the OS starts saving at 30%).

Battery calibration didn't helped. But I noticed strange thing:
My friend also has htc sensation and his battery fully charges in 4hours. I exchanged my battery with him and charging time is same! He fully charged my battery from 14% to 100% 4 hours and my phone still charges very slow. I started charge his battery from 44%, at first it was charging very fast, but after 4hours it charged only to 88%. I rebooted phone and then it showed 100%. Where is the problem? My phones charges very slow with any battery. I don't want to reboot it every time to show 100%

Wiping battery stats won't help you.
Put your phone to charge overnight, discharge it completely. Do this for a few days.
Do not wipe battery stats, or you'll have to go all over again.
Happy to help.
