It depends what type... I know one where you'd almost have to drain it but not all the way then fully charge it would make the battery life longer than having its life cut short.....

Try this technique which I used on SE XPERIA X10:
Charged the phone to 100% and while still plugged to the charger remove the battery wait 5 seconds put the battery back unplug the phone switch it back on and plug back into the charger. Ur battery should now show 88% charge not 100%. will wipe the battery stats as well when I will fully charge to see if it makes a difference.

Need to fully discharge the battery at least once a month until the phone off .. then you load up to 100%, and doing what was said above, remove the battery, and turns the charge again for up to 100%

In spite of reading a bit one sees immediately

A simpler way is just to use Battery Calibration app, it can be found on the market.

Is it a bad thing to charge the battery at 50% still?

Charging phone at overnight is bad?

Hey forums, very simple question is charging the phone overnight bad for the infuse? I always get a warning to plug out the phone in the morning. Can overcharging be bad for my battery? Merci.

Do you mean that you get a warning after leaving it plugged in all night?
If so, check to make sure that your cable is connected properly. On some cables, the connectors are not fully touching.

What I was trying to say is. Usually the battery is able to charge fully overnight. But then it probably just sits there with the charger in until morning when I pull it out. I was wondering if the extra time its charging on full battery is bad.

Nope, its not bad, whenever the phone reaches 100% it disconnects the charger till it drops to 95%,then it starts charging again and so on,at least that's the case with my phone on official and custom roms

Nope i've had 20 diff phones and never followed charging cycles and all that let your battery run down and charge it up nonsense. Never had any battery issues ever with any of my phones

I put it on charge when I go to bed, and unplug it when I wake up. Just make sure to keep it in open where the phone isn't covered.

Thanks for the responses! I wont worry about this anymore.

Make sure to always use quality, reputable chargers and not the ones you buy at the flea market that say "Made in the Democratic Republic of the Congo".

Lol no problem. I still have the charger that came with it

Yes it is bad, because it will overcharge your battery. It takes a while, but if you overcharge your battery constantly then the battery life slowly starts decreasing until it dies.

In a sense this is correct as the same as playing on your phone while its charging I wonder if we have a unplug app when I was on the evo we had a app that would disconnected the charger when full and wouldn't read it until the battery was at 80%

The phone doesn't actually charge the battery to 100% unless you're using an SBC kernel. You can leave it on the charger as long as you want and it will never overcharge unless you have some kind of malfunction.

Been only charging overnight since I got the phone last May.

I use my phone as alarm and it charges every night since I've had it. No issues with battery unless I flash a rom that is a battery hog.

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.

My Nexus 5 gets pretty hot while charging (charger too), is this normal?

So yeah I wanted to charge it yesterday and after about an hour the charger was really hot. The phone itself was hot too but not as much as the charger. Is this normal?
Thanks!

It's charging well, I think the first time it took less than an hour to charge but now it takes about 1hr and 20min. I also experienced some major battery drain by Google Services the second or third time I charged it. Today Google Play Services went from 52% down to 19%. I hope it goes to 0 from now on. Thank you.

Oke, enjoy your phone and flash away if you want to

I take it your charging the phone while its on, and googles services are to blame.
Try charge when the phone is off and see if it still gets hot,
It will get hot while something intensive is going on.

I plugged in the charger about 20-30 mins. ago and the phone went to 40% from 5%. The charger it's pretty warm now. The phone it's not as warm, just a bit. I'm interested to know if the process of charging in certain circumstances (like the charger being too hot) has any influence on some apps such as Services. Thank you guys for your replies.

[Q] About battery

So guys i just bought this phone few days ago, and the first charge was only untill 96% and then i unplugged it, because its take too long... is this can cause some problem to my battery? or is it still safe??

Did you use the original charger and cable? Of you don't use those you'll experience slow charging. Charging only to 96% won't have any bad effects on your battery.

so youre saying that my battery is still normal?
and btw yeah i use the original cable and charger, now i can charged to 100% after i let my phone die (0%) and then charge it uninterrupted overnight (like about 6hours)

Yes the battery should be perfectly ok. Sometimes the calibration can be a bit off but you've charged to 100% now it's all good.

I don't think charging your phone to 96% or whatever will cause any damage to your battery and why would it?

hey i have another question, this thing have been in my head for a while now i just wanted to make it clear for me
for example i have 80% of battery then charged it untill 85% and then unplugged it and use it for a while until drop to lets say 80% again, and then charged it again to 85%
is that also safe to do?
i just did that when unlocking bootloader and installing twrp recovery, seems like my battery been draining pretty fast after that..
sorry if this noob question annoy you, i just want to make it clear

That's perfectly fine with a lithium battery. Small top-up changes are actually preferred. It isn't recommended you let the phone fully discharge very often, it also isn't recommended to keep it at peak voltage (100%) for very long (try not to charge overnight). A lithium battery is at its healthiest within the 40%-80% range. So yeah, top-up charges are perfectly fine. About every 30-40 charge cycles (roughly once a month is fine) you should do a calibration by discharging almost fully (from 100%), then charging back to 100%.
