[Q] Charging Overnight?

Does anyone know if charging this phone overnight will "mess up" the battery , because I use an alarm every morning and I need the phone to be on when I wake up. I checked at a lot of sites ( and of course xda too) but i couldn't find the final answer?

No it will not. It has a charge script that stops when it reaches 100% then monitors the battery after that and will trickle charge when it drops a couple of percent.

Actually this is a process used to calibrate battery when you first buy one or is the first time you buy a phone. You drain it and charge it overnight. I do this too but not recently because airplane mode allows for no percentage drop..... I don't believe it is harmful but may prove to be over an extended period as are many things. Id say just turn the phone on airplane mode and it shouldn't drop but 1-2 if any percentage.

No it is not harmful. However any rechargeable battery wears over time. I have charged my phone overnight since the September 2010 without issue.

No it will not harm it is what I discovered
Here are some sources that say it will not damage it:

Honestly for me to say, its your choice...
I leave mine in, it's much more convienient...

A general charge overnight will not harm ur battery. But every now and then..u want to perform a charge cycle. Fully chargee it, and let it drain completely. U do this twice. It just basically resets the battery cells. Our phones use a lithium-ion battery plus..its the improved lith battery.

NO. NO. NO. Uberpinguin, the one who posts cm7, hates battery calibration, and I'll preach his message for him. Cycling the battery is stupid, it wears life, and wiping battery stats is stupid. Each battery has a specific uuid (I think that's what it is) that tells batterystats.bin what battery it is, and then it THEN locates the info it needs. Not "oh hey, my phone is calibrated for someone elses battery".

Explain ****ty battery life then when i don't calibrate it when i flash a rom.
When i flashed over to CM7 my phone was getting on average 10-14Hrs depending on usage if i was heavily using it it would be from 6-8Hrs.
After i calibrated it i went from 6-8 on heavy to 12-15 on Heavy and medium usage went from 10-14 to 18-20Hrs. And minimal use ending me up with 24+Hrs
So please explain? because i hate calibrating it but it works.

Ugo, have u ever hard tested a battery? My assumption is no. Are u aware that per manufacture and engineering specs, sometime u have to do calibration. Have u performed appropriate research? I will link 1000 sources that will stat, u should cycle battery once in awhile. Its like a pc..there is the hardware function and there is the software function. Are u an advanced mobile technician? Are u. A mobile engineer? I use to be a technician. Ur basing ur statment from someone else. Have u done this "yourself"?

Battery drain always seems terrible for a short time after flashing a new rom. It does clear up.
Letting your battery drain completely is NOT good for your phone, though I'm unaware of what how it may affect the battery itself. But as I understand it, it is not necessary in any way for the battery itself- so it's useless and doing so will only help you corrupt the data on your phone.
I've been charging mine nightly since Nov 2010 and it's fine.
Those of you with serious battery drain - do yourself a favor and try staying on the same rom for more than 36 hours.

That is an EXT4/journaling thing and has nothing to do with your phone. MTD and RFS do not have this problem. At time of purchase the Techs and Samsung recommend this battery cycling and running the battery all the way down.

Battery life problem!!!!

My wildfire s battery life is very bad.
When fully charged,the phone works for a long time without even 1% drop but when it goes down to 99% then battery began to discharge quickly.
Is there any way to solve this?

HTC is popular for having low battery life so it can't be blamed but
U can underclock it
Sent from my HTC Wildfire S A510e using xda premium

solution
in my case, I left the phone to discharge and shut off completely. Then, with the last drop of battery juice, I powered it on into CWM recovery and went to advanced -> clear battery stats. Afterwards plug it and charge it to 100% (until the LED turns green), preferably with the phone off.
I know some say it's only a placebo effect, but in my case it makes my 806Mhz overclocked & automatic sync enabled phone to last around 35hours.

You dont want to empty battery in our wfs completely ever
Lition-ion batteries dont like full dischard and they tend to loose juice after that process
Good tip-never discharge your phone so you can't turn him on without charger

My battery life sucks, I think its the quality of HTC batterys, I need to go on eBay and buy a new one
Sent from my HTC_A510c using xda premium

my battery is doing the same, plus it never charges 100%, stops on about 90%, after few hours of charging it gets to about 91

I've never had any real problems with my battery life, but with the CM9 that I'm running as a daily at the moment, it just can hold up a long working day till I get home. Really annoying, but damn I like CM9 to much ! I hope that get's sorted quickly!

Agree with that,its quite correct.
Also guys try this...
-HTC checkin service apk...its a bigeest consumer next to wifi,cell,and display...amongst two top ones.
Do following:download rom toolbox or titanium backup or any similar app
here the links https://play.google.com/store/apps/...wxLDEsImNvbS5qcnVtbXkubGliZXJ0eS50b29sYm94Il0.
https://play.google.com/store/apps/...DEsImNvbS5rZXJhbWlkYXMuVGl0YW5pdW1CYWNrdXAiXQ..
with this in app manager find that app...long press on it and choose FREEZE (u can unfreeze it later if you want)...also freeze the maps if not using them...etc...just DO NOT MESS with system apps if you dont know what you are doing.
I prefer Romtoolbox cause its all in one app...you can also wipe your battery stats from there as well...great app for root users...try it out
Hope i helped with giving some of you some ideas what can you do amongst other battery tips im sure you all know by now.
Enjoy

Battery calibration
if you use a custom rom you have to calibrate your battery with néma's battery calibration you can find it on the market .my battery last longer since i did it at any rom instalation

I freezed those two apps with titanium backup.i wil report later about battery life.
Thanx for the info.

How to calibirate battery on miracle v4

Hi can anybody help on calibirating battery on miracle v4 rom

no....nothing can be done
Sent from my GT-S5830 using xda premium

Do bump charging instead of battery calibration. Search it on google.

-Charge your phone to 100%
-Use this battery Calibration app:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=de
This app needs root
-Then let your phone discharge until it turns off itself
Notice: in this time you're not allowed to plug the phone to the pc or to the charger again until it turns off
-after it turns off plug the phone to the charger and let it charge without breaks to 100%
-Done

I recall that battery calibration was bogus, there was a post which explained why it was bogus in detail. In other words, don't bother, but charge your battery around 50% if you want a healthy battery.

http://bit.ly/KZdfJJ - Why cant you just google it like he said?
also you can go to recovery and select wipe batterystats.bin
Calibrating your battery does not give you extra battery life, just improves the battery level indicator. Android calibrates battery itself anyway (when battery info change to a few seconds)

batter calibration is of no use i have tested it many times on many roms. our ace has not a good battery. so follow common steps like brightness to 0, application background off etc etc.

thnx will do as u suggested

There is a way to get good battery life in miracle v4 but it took me about 5 days now I get 16 hours off battery with heavy use and about 22 hours for normal use
How I did this
1.let your battery totally die
2.leave your phone off and give full charge
3.still with your charger pluged in boot to cwm recovery
4.now select advanced then wipe battery status
5.now still with with charger pluged in reboot you phone
6.when your phone is fully booted remove charger(you will notice the battery will drop to about 86% in about 10 mins the first time but will get better each time you repeat all these step)
NOTE:I have done this on my wife's s.g.ace with rom miracle v4
And on my Sony Ericsson x8 with many different Rom's
And on my friends Sony Ericsson x10i with many different rom's
YOU MUST USE MAINS CHARGER NOT USB FROM P.C OR LAPTOP AS USB WILL ONLY TRICKLE CHARGE.

according to the miracle v4 developers the battery indicator doesn't indicate about the battery properly ...will charge now to the max even after 100 % and will let you know what happens

I know battery calibration is useless, but how can ace have better accurate reading. And my problem is that whenever my phone deep sleep for a while and i start to use, the battery decrease rapidly after screen in for a while. Its like the battery is leaking even in deep sleep. Is this a common problem for ace user?

Calibration does not improve or increase battery life. It would just help in getting a more accurate battery level reading. Or so i read somewhere.

This is not needed anymore.
if the battery takes to long to kill then simply its already calibrated
many people don't know how a none-calibrated battery acts and think "battery life is great but it will get better later!"
if anyone of you happened to have a nokia phone in year 2000ish and still have it around i recommend you to go get a replacement battery for it and see for your self
unless the new battery jumps from 100% down to like 80/70% in no time then take too long to drain from 10% or something like that (in short battery acting weird)
then its already calibrated which is the case in all new phones/batteries
TL;DR
unless the battery is acting weird and not taking too long to kill then you dont need to do that

Thanks a lot I got my retail set from a carrier, so glad to have joined the note 2 community coming from the s3 :X so I just charge it up to full as per normal yes?
Sent from my GT-N7105 using xda app-developers app

This charging a long time first usage is also an old thing from the old nicd and nimh batteries..
in fact li-po and li-ion wont even charge after they are done, overcharging them means they explode/burn or get damaged.
there are built in safety features to prevent that.
and pulling it down to 0% means nothing since modern nimh, li-po, li-ion batteries don't got the memory effect.
actually going down to 0% would only test if the low voltage cutoff works as it should or if you damage your battery.

no need for that!

You can preserve the life of you battery by not fully charging it and you can damage it by draining completely. I've no source for this information.

[Q] Battery Issue

So here's my problem:
About few weeks ago, my battery started to fooling with me. When I use it for Facebook, Twitter and normal web surfing, the battery goes down, fast, from 100% to 10% took only about one hour plus. Then I left it aside. Check it again after 30 minutes, the battery went up to 27%. So I think battery was miscalibrated so I tried to calibrate the battery using all the guides I can find on the net for weeks but none worked.
So what should I do? Should I change a new battery?

Did u try calibrate it properly, eg.. wait till its charged fully then wipe them. using an app from playstore is the best way. If u wipe stats when its not charged100% then it will start jumping percentages.

Well try to underclock it and make the screen brightness lowest. Try to look at the battery stats too as you may have an app which is using a lot of resources of your phone. If you can live without your phone then switch it off completely, try to find the charger with highest mAh output (the higher the mAh output is the quicker it is charging), connect your turned off phone to the charger, make sure it's charging, leave it for 2 days charging like this and then disconnect it, boot it straight to the recovery, wipe the battery stats from recovery. If this is not going to help then I seriously have no idea what else you can do.

Phone's not overclocked, brightness is always low, I used it for texting my gf for whole day, played word search for a while and my phone left 50%, no data no WiFi nothing, When I turned on WiFi and keep using it, battery drops fast. Reached 4% I left it, went back to 16%, continue using, left 4 % again, left it again went back to 10%, then I used it till 4% again, now left 6%. Using stock charger but with different cable since my stock cable is broken. Is that related? If yes I'm going to get a new charger.
