charging battery - Galaxy S II Q&A, Help & Troubleshooting

i red some diffrent idea about battery and i got confused ! which one is better for battery health?
1-when battery is 30-40% connect to charger for full charge
2- when battery is about 1-10% connect to charget for full charge .

Just don't empty the battery ( 0% ).. idk if it's true, but a lot of people advised not to empty battery cause it's Li-ion..
I suggest you charge as soon as the phone notifies that it can be charged

Li-ion doesnt have memory effect so it isnt important when you charge it, imagine if jou have car dock you charge it every time you put the phone
in and the batery is still ok.

Every few months I empty the battery completely and charge it from zero and I do this because after flashing lots of firmwares etc the battery seems to give funny readings. This might not be correct procedure but it works for me.

[Q] HD2 Always connected via USB can harm battery?

Hello, when I'm in office I have my HD2 always "plugged" to a cradle connected to my PC via USB. I haven't selected the option to disconnect charging when the device is connected to a PC and now I wonder if the fact to keep connected the HD2 to a charging source yet when the charge is 100% can harm battery and reduce its "lifetime"....I have an app that monitors the battery temperature and this temperature has the same values when the battery is charging as well when the battery is fully charged but the HD2 is still connected...
Opinions about?
Thanks
Andrea
There is no problem in doing that!

Just be happy that You always have a fully charged HD2
When it´s 100% full it is simply not charged any more ........... no sweat
And you have the option of no charge when connected to a PC
Li-on batteries are happy to be bumped charged. Keep them charged and it will be good
Thanks to everybody, guys!!

I am using phone alarm which stops charging battery via USB when its 100%,to prevent overheating.It'll charge again when below 90%.
Overheating is the only problem there is i believe...no issues with lifetime of battery...

I think yes !
But only if you charge the battery when it's not low !
Basically charging it when it's more than 30 % can shorten the battery life !

Battery "lifetime" is dependant on a number of factors, but, to maximise the useful capacity just charge it as often as you can. Then when not on charge you will get the "best" performance" from it.

Lithium batteries last longer with top up charges rather than deep charges.
As PA49 says, keep it topped up as often as possible.

my phone never get more than 91% battery charge

need help with this problen
flash into xrecovery and wipe battery stats!
Also, calibrate your battery. Fully charge, remove battery, reinstall battery, fully charge again. Repeat 2-3 times until says 100%.
Stock charges to around 88%.

Read this thread: [GUIDE] X10 Battery Calibration
My battery is also causing trouble
I put the phone in charger is loading the phone up to 88 then stops
And when I take out and put in the charger my phone charges up to 100
While the charger still connected is again removed the battery to 88
I have to use the directory that you brought?
Sorry for my english lol
Yeah calibrating your battery almost always will help. Check the market if you haven't yet. There are a couple Apps that will help do it.

Ok thnx
dont use your phone while in charge and then see the status of ur battery.. if u use ur phone while charging, it never charges up fully..
Pls hit a thanks if u r satisfied
I experience this when I leave my X10 charging all night long (turned on). It seems it charges up to 100% and then keeps draining it, despite the connected charger. Have you ever tried offline charging?
I want to charge it when it is turned off. But I do not know if he filled it to the end. Because I do not know what percentage has
That there is no sign of a fully charged battery

[Q] URJENT help needed battery fall in 2 minutes [VIDEO]

hi people
please check this 2 min video and you will come to know what i am trying to say and what help i need
Note : this video is raw not edited.
100% to 81% in just 2 min
i use :
1. ics final by jusada
2. lagfreev1
3. volume battery drain fix
i recently did battery calibration also both by software and cwm recovery wipe method. due tho this i have to remain under power or other way is to switch off and charge, but guys i can't switch off my device its always ringing and my business also.
Youtube video link as i don't know how to embed here :

Calibrate battery:
Turn phone off
Charge until 100% appears on the screen.
Turn off charger and remove battery
Put battery back in battery after at least 90 seconds.
Use CWM to boot into recovery
Go to advanced and delete Battery Stats
Reboot phone & DO NOT recharge
When the phone reaches 10% charge, put back on charge.
Remember all battery start to loose their charge if used constantly. Re chargable batteries become less effective over time.
Wy u disconnect the charger when it reaches 100%?? Its fake dude. Wait till the system reminds u in the notification that battery charged!!.. Some ROMs might hav removed that.. Seriously charge ur battery from 10% to 100% for 3 HRS...

It's not fake. I charged for six hours straight and have th same result as this guy. cooltt is correct: the effectiveness of rechargable batteries degrade over time.

Ok everyone calm down.
My original post about how to calibrate this battery is correct, i'm using ICS final no tweaks by Jusada and i get the 100% charged confirmation when i charge with phone switched off.
I know some custom roms don't have this feature but you can still charge to capacity with the phone on, when it reaches 100% turn the phone off and charge for a further 20 mins.
This battery takes 2hrs 42 mins to charge from dead but you should never allow it to die as it strains the internal structure of the battery.
The battery icon is not a true representation of the remaining charge until the phone has been used over a couple of days and charged up at least once, this is the way all rechargerble batteries work
ya actually if i charge with my device off i get full charge in 2:30 to 3 hours but when i switch on and charge then it charges from dead to 100 in just 1:30 hours so by this i know we are not getting full charge while on.
but guys this is bad we need to find some way out this is really not good that we have to switch off our devices as there can be some emergency also, never did in my nokia,blackberry.
by the way in some thread i read this trick so today i followed this and will post my result after 24 hours :
How to Calibrate your battery ; guide by Hiroshirou :
1. (phone on) charge to 100% until it actually says full in settings > about phone > status > battery status
2. unplug charger and turn off phone
3. (phone off) plug charger in until it charges to 100%
4. unplug charger and power it on
5. (phone on) plug the charger in and charge it to 100%
6. unplug charger and reboot phone to recovery (into cwm5)
7. go to advanced and clear battery stats.
8. turn on the the phone and charge it to 100% - DONE!

Alright. I once accidently put my speaker output into 3.5mm jack instead of speaker input in my last phone and my battery didn't use to last more than 30 minutes. Maybe you can try to swap batteries temporarily to check if it's a battery issue or phone/software issue! That will narrow it down.
its a software issue only as my battery is new i purchased 1 month ago.
Backup data and perform a fresh installation and calibrate again.
It this doesn't work, it's definitely a hardware issue.
P.s. age doesn't matter. A bad battery will go bad whenever it wants to. I will still suggest you to try swapping batteries first to narrow down the issue. Try krne mein kya jata hai?
oki i am on a test of a procedure that will complete in 24 hours after that i will try to use fresh installation right now i am busy in editing custom ROM for me so i guess have to wait for battery to got down till 10%.

(Q) battery charging problem

Hi all,
Wanna ask did u all facing the same problem with me, when I charge my phone battery to 100% the charging will stop and the battery will drop until 80% the charging will start again is it normal or my phone problem .. need advised
Sent from my HTC EVO 3D X515m using xda premium
mine does the same but only drops to 90.. i think it does that so we dont fry our batterys when we leave them on the charger to long..

I'm facing battery issues from few days, my 3d would charge fine till the battery level reaches around 80% but then the level doesnot want to rise up.After a reboot it shows battery level around 98%. Also my battery charges above the max limit I.e. between 4350-4355mv when it reaches near 99% but it never goes to 100% . Is it the battery issue or is it my cable which is wearing out from the ends ?
Everything was working fine before few days . No issues , with the weared out cable.
Will the battery swell if I continue to charge it at this voltage ?
Are you using the stock battery ??

Battery Calibration And Bump Charging.

First and foremost...lets get this out of the way..if u want more battery life..get a newer more powerful battery...thats the best option..
But if you still wanna stick with your current battery and still want improvements..here is a little something i want to tell you..
Obviously you might have searched about how to improve and come across the method known as calibration.. this is the method as described by one of our members..
nickrule1896 said:
Steps:
1. Before flashing a new rom, use root explorer (with read/write set) to delete the file "batterystats.bin" stored in /data/system/.
2. Charge your phone with it being turned off.
3. After it is fully charged(100%), take out its battery without plugging off the power supply.
4. Wait for a few moments, and a ? sign will appear.
5. Put your battery back in. You should see that the battery percentage increases quickly to 60%. If it increases to 100% with seconds, please skip to step 6.
6. If it stops increasing at 60%, let the phone continue to charge until 100%(takes quite a while)
7. Once it reaches 100%, let it charge for a further 15-20 minutes.
8. Once that's done, you can boot to OpenRecovery and flash your rom!!!
Alternative way of calibration(thanks a lot zeppelinrox!!!):
http://forum.xda-developers.com/showpost.php?p=11803458&postcount=10
This method allows you to calibrate the battery and use ur phone at the same time!!!

This method..simply put is useless...
If you dont believe me...then read this post..http://forum.xda-developers.com/showthread.php?t=1460553
and subsequently read this post by Google Engineer Dianne Hackborn(funny surname i tell u) and you'll finally believe Battery calibration is just a myth..unless ofcourse you dont believe you know more about Android than the people who designed it
https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
As is mentioned.. "It has no impact on your battery life" !!!
So...BATTERY CALIBRATION IS JUST A MYTH!!! Still...if you dont believe me..continue following your stupid practices..
Coming onto bump charging...
When your phone shows u fully charged it is actually charged only till 90-95% and thus u may experience a sudden decrease in battery %age after u unplug the charger...
The method for bump charging as you ardent ritualists may already know is as follows..
" Phone on, charge to full
Shut Phone off, charge to full
Phone back on, charge to full, use like normal. "
The main disadvantage of this is that it increases your battery voltage...Also in some case of sudden overvoltage while charging this can damage your battery...what for? 5% increase...
also..all that extra heat is bad for the lithium batteries...
Therefore 95% battery is good enough for daily use
so..if you really want to improve battery life...dump all these methods and just buy a more powerful battery and give it a month to give you proper results..all new batteries require at most a month to work to their full potential...
P.S. : come to think of buying a new battery...this idea may be very helpful to you if you do happen to own a Galaxy NOTE..

If this is all a myth, and I'm none the wiser, why is my battery percentage all over the place? For example, went on a hike listening to music etc. Ran the battery out. Got home, plugged into charger, turned on and it said I had 46% though when I first plugged it (while off) the battery symbol showed obviously barely anything.

Android is very....insensitive when it comes to battery .
Android keeps track of the battery using a permanently running Battery Service , which polls at a certaon interval....
For our phone , deep sleep will affect battery polling and thus your battery will be displayed as being larger than it really is .

Heyy guys I have a problem regarding the battery life on my fone
On any rom be it cm7 cm9 or cm10 whenever i charge my fone to say for eg. 65-70% and unplug the charger battery starts draining quickly until it reaches a particular point like (45-50%) then the drain becomes somewhat stable
However when i charge the phone fully (ie.100%) the battery depreciates economically (like on stock)
This means I have to charge the battery full in order to prevent for drain
What should i do to prevent this from happening? Or should I buy a new battery
Any Help Appreciated
In my experience with any lithium battery not just android increase battery life by let it die fully so it wont turn on at all then charge till 100% and no harm done by leaving an extra 20 mins leave charger in while turning on should vastly improve an older battery

I am afraid you're wrong in letting old batteries to drain completely man...when battery is new like say within 150 cycles what you said is true but as it becomes old it's better to charge it when it goes below 15...coz the chemicals will become inactive and won't be efficient in taking up charge

All I know about Li-ion batteries is that when I dismantle them the real lithium strip inside reacts with the air and decomposes :/
I give up writing anymore signatures.
