Battery Swapping !! - Galaxy S II Q&A, Help & Troubleshooting

Hey Guys,
From the past month or so i have been swapping two original 1650mah batteries once in every 2 days on my SGS2.
I charge one of the battery thru external Wall charger device almost everyday.
A frind of mine was telling me it is not a good idea to swap battries as it may brick the phone and also reduce performance for both the battries and even the calibration will not be correct..
how far is it true ? will there be any issue on my phone if i keep swapping batteries regularly ?

I rotate three batteries and it's fine. Don't listen to your friend. What's his basis?

That's nonsense. Is your friend an iphone user? Because it sounds like something someone with an integrated battery would say...
I swap between my stock and anker battery quite often, no issues.

Some phones have a "coulomb counter" type fuel gauge (google it for more details) - such gauges require calibration, and can get confused by a battery swap.
The fuel gauge in our phone requires no calibration. Swapping batteries won't brick the phone and won't throw off the gauge.
The one thing I will say is: If you are not using a battery, and do not plan on using it soon, do not store it fully charged. Lithium-ion batteries are best stored at around 50-60% state of charge, they will lose capacity rapidly if stored at full charge.

Using another battery

Hi guys:
Is it possible to use a battery from another phone? Because sometimes chinese mobiles can be compatible with Nokia's batteries and for a little amount of money, we can get some cooler Nokia's ones.
I'm getting a ZTE Blade this week, so I will tell you my impressions ASAP.
Regards.
I wouldn't recommend using any other battery than the official one provided. You're asking for trouble otherwise.
Why not? If it has the same voltage and fits perfect, there isnt any reason for using this battery. There are other manufacturers of mobile phone batteries that make compatible batteries, so It wouldnt have any problem.
Anyone tried it? I will make a study of MP batteries and then I will tell you if I found something interesting.
Regards
why would you do that when a new oem battery is so affordable?

More capacity power than the stock one. Finally, I have bought an emergency charger for 10 euros, that have 1900 mah and its affordable for my Samsung Wave and this phone.
Hope that it will solve all battery problems.
Regards.

OK, give us some results once you have

Interested aswell in the review,was considering carrying a spare battery but this looks handier.
I considered using another battery too, but this option has multilple advantages:
1) It has 1900 mhAmp, so it lefts 500 mAmphs free to make another charge.
2) I'm using two smartphones, so I can charge both ones.
3) I don't need another charger or charging it in the phone and removing it. I just charge the emergency charger and I can use the phone again.
BTW, my ZTE Blade seems to be the AMOLED version, with low battery consumption. I'm using stock GB firmware, and after a day using 2G network, WiFi, playing Angry Birds for 30 minutes, using Whatsapp and a few phone calls, I have 30% left. SO I'm quite impressed with battery life, hope it will be as good as my Samsung Wave (I use it around 2-3 days with no problems)
I will make a full review when I will receive the charger.
Regards.
I bought the 2800mAh version of that charger, and man does it work great.
I suppose it's the only must have accessory I can think of to a smartphone.
1500mAh Battery for ZTE San Francisco Blade on ebay i dont have enough posts to paste the link.
not sure if its any good,has anyone tried it?
of course u can
I got this one: (1500mah) it works .
http://www.ebay.com.au/itm/ws/eBayISAPI.dll?ViewItem&item=180712611702
how much time does it take to full charge the battery?? think u need a bigger capacity charger with this to charge it speedily...

[Q] check for original charger

i bought a charger online it looks very much like the original bundled one. However i have a couple of questions
1. is there a way i can check the output quality using the phone itself and not a multimeter . Like variation in voltage/current?
2. using a multimeter do i have to tear apart the charger to check the output quality.
any inputs are welcome

Depends on what you mean by 'output quality'. If you mean the ripple (noise), especially in response to load changes, then no, you can't without oscilloscope and dummy load.
If you do not have this measuring equipment, then I would use these two simple tests:
does the empty phone fully charge within 2 - 3 hours ?
does the touchscreen stay responsive while charging ?
If you can answer both of these questions with yes then one could assume the charger is of good quality.
thanx for an informative reply man. the thing is i use usb charger usually battery is 8 months old . i dont know how long it will charger to recharge. giving these conditions u still think it will take 2-3 hours to charge ? yes the touchscreen stays remains but i think there is the usual "noise " that makes minor error in touchscreen smoothness. do u understand wat i am trying to tell u.

the minor 'touch screen smoothness' issue will be there while charging thro wall charger for sure and also the charging time do wary depending on how old the battery is

If the battery is fine (and it should still be after 8 months) charging of an empty battery should happen within 2 - 3 hours.

If you are able to normally operate your phone while charging, then this is ok.
ok. i will do that and get back to u guys. just one thing. wat info can i get from phone regarding charging current /voltage ? also the original capacity was 1650 mAh . can i recalibrate and get the "new" mAh is there anything like this ? i calibrate my laptop' battery every two months and get its capacity in terms of mW. anything similar to phones ?

Search the play store for Battery Monitor Widget. It can give you some more information about your battery, charging, discharging etc.

[Q] Anyone else use spare battery?

Just curious to know who else uses a spare battery? i bought a recharger kit like the one in pic and love it. just pop the cover, take battery out and replace with the fresh one and your good to go.

Except this is more of a discussion about the question, not really Q&A material.
OP I don't use one, mainly because I don't have one if I did I would probably use it.
No offence OP, but this should be in the accessories forum, I do believe, so on your behalf ©®™ for moving
Bought two anker batteries at the same time I bought the phone, the Samsung battery is still in the box and I've never used the phone to charge. Swap the battery between the phone and charger every second morning, it's the first smart phone I've not had to worry about battery life.

I've always been a battery swapper since the early Nokia days. Can't bear the thought of not having a fresh battery there ready to go when I am. No waiting for phone to charge at the last minute when heading out of the door.
Ah, maybe I should note that for most tasks I use my Nexus 7 :laugh:. Oops-a-daisy. I use Galaxy S 3 mainly for music and when I study on bus. No gaming or movies.

boomboomer I was looking at the anker batteries when i first got the phone last year too.. but ended up going with this official samsung kit that had a spare that game with it. What capacity Anker's did you end up getting? I had a look at those big 4400mAh ones as a backup for when travelling overseas but never went through with getting one.
the one thing i hated about the iphone 4 I had last was waiting for sufficient charge whenever I had to quickly be somewhere unexpectedly. Some times Id go out for a few beers in the evening with a low charge thinking id be home soon.. end up having many, many more and so Id end up with a dead phone as im trying to find a way home.
Can honestly say that I havent ever had that issue again since investing in this phone and extra battery haha.
The ankers are the same physical size as the standard battery, just 2200mAh. The only draw back is the capacity drops quickly once below 10%, but I usually swap battery when it gets below 20%.

I use one. love it. All Samsung Galaxy S III phones ships with an extra battery so why not use it? So convenient to have one always charged in the battery charger and your phone charged with wireless charging. Qi!
R: [Q] Anyone else use spare battery?
I bkught a 2800mah battery a while ago...great, lasts a lot.
If i ever need another battery i will put back the old one...i could of course get ANOTHER 2800 and then keep switchingg it...but it would be tiresome...thats why they made rechargeable batterues in the first place...as soon as the battery wears out (5months my guess it will be 40-50% worse than when u first started using it) get another one. If you go on a trip and forget the charger, pop spare under the hood and hit low energy mode!

Attention for every fellow xdaian with battery problem in LG L9

Attention for battery issuses...
Recently my phone started acting weird...like my battery charging to full in more than 4 and a half hours...discharging quickly then in 6 hours...or sometimes i noticed my battery percentage struck at a level(example at 95%) and the charge not going up from 95% even after connecting charger for more than a hour..
What happened. .
Since i am a 4 year old Lg mobile customer(started with THE VERY FIRST OPTIMUS-GT540) i knew the service centre executives very well..when i decided to pay em a visit and explained my problem...they checked my battery,charger,and its cable. After that they took my phone and told me that IT WAS NOT BATTERY PROBLEM...RATHER THAN THE CHARGE PORT PROBLEM. .
EVERY L9 OWNER CAN CHECK IT...
there is a major design defect in every L9.as you can see, .the charge pin is placed way past (inside the phone ) from the actual charging pin hole in L9 body...which is rare considering in every phone the charging pin is placed right next to outermost part of hole created in the phones body...
OKAY...BUT WHATS THE PROBLEM WITH THAT. ..
the problem is ..since i/o port or charging port is way inside...so it is eventually going to get screwed faster by multiple insertion of charging cable into it(for charging your phone Lol) that means its a major defect and because of this design flaw...your charging pin is going to become wreck very sooner as compared to other mobile devices(depends upon your usage too...mine got f##kd in 4 months due to heavy usage). So if you are experiencing any problems related to battery like i did...dont blame the poor lithium ion fellow...instead get your port replaced...
#Note..ive been given an appointment of wednesday to change it for free..(in warranty) normally it costs around $15 in India.
#May your phone remain intact as long as it belongs to you...
Tmobile has no idea what about any port defect, neither did the LG rep I talked to.
this is total b.s.
No bs! My old LG (P970) already had the.same problem. Many devices had broken USB ports, but of course it either takes a lot time, or a rough/intense usage, to break that thing.
Just my 2 cents.

Can the port be replaced for a reasonable fee or the phone is dead if that occurs?
people break their ports because they treat them poorly. to say the l9 has a major design flaw is laughable. sure there are problems with individual handsets but to make users think their bad battery life is a result of the port being a design flaw and just to get it replaced is foolish. usually when i see port problems at work it's because the people are idiots and damage it themselves or dump liquid on it, get stuff jammed in there. i feel like the l9 is well above average in this regard, in fact at least on my handset the port feels better than most devices i've had my hands on. treat your things well and they will work like they should.

I see your point, but I feel differently. Yes there are lots of idiots, who damage their ports, but I think it is a design flaw concerning all micro USB ports in general.
My port e.g doesnt seem to be straight. Sometimes i gotta fiddle a little, till I get the cable in. Did you ever try to get the cable in, when it was dark? It s pretty sure, you ll try it the wrong way around.
Iphone port is a perfect example, of what it should look and be like.
Oh and battery drain probably really has got nothing to do with it.

port is not defective...but the way it is placed inside the phone body makes its wear and tear a lot to happen than other phones...its not a company agreed defect..but the port gets ripped off a lot faster due to its deep placing..that's all.

please read carefully...i said if your charge gets stuck at a level example 95% even if u connected charger for a while or your phone disconnects/reconnects from charge when given a little tap...then its a i/o port defect..if this defect persists in your phone...then your BATTERY wont be charged in less than 3 hours..and will give erratic battery life response. .rest known...every machine performs different to its master.i hope u understand

Why do you need to replace the battery so often? An average L9 battery lasts 1 day easily on CM and 1.5/2 days on stock.

you have to actually TEST the battery to see if it's good. i work with Cadex 7400ER.. google it. its a commercial analyzer. People get rid of good batteries all the time. I have a box at work with good smartphone batteries.. most samsung. I took a good hard look at my device and i couldnt find anything to support your statement devil, sorry. I get days on my battery.. on 10g, 20d, and CM 10.1 and 10.2. Sometimes had to get some wakelocks under control but no big deal after that. The phone model i've seen the most port problems on is the Samsung Galaxy S 2 Epic 4g Sprint. love you guys.

Then buy an ICrap or old BlackBerry and get a swirl... live free with equally fast discharge...
Fast charge is disabled by default (on obvious reasons, google it), but hey... anyone is free to make it work if he can find a proper solution.
Said that, 3 hrs should be more like 2 hours or 2 hours and a a half... but seen OP never stated specs, it's all right.

In fact, the most other phones charge with ~1A+ and they don't have any big draing issues in common. It doesn't matter which OS they run.

ill never buy an iphone,s2 does charge really slowly and s3 too,but s4 no,so its a matter of samsungs technology which is slow,plus i agree that battery is good for 1650,i guess ill have to get used to it.Im going to send it to samsung to see if they can change something,like the usb port to handle more voltage,do u guys think its possible?

Use s4 charger. It has 1amp output current. .
But not recommended though.

Oh, you're very polite :/
In fact, the most other phones charge with ~1A+ and they don't have any big draing issues in common. It doesn't matter which OS they run.

Yes I am , thank you, cause the slow charge issue was elaborated and mentioned so many time around XDA but seems no one cares to search and read.
This phone with and with original charger, and AFTER teh update from Gingerbread to ICS/JB is charging as per specs. On Gingerbread there was a flaw that permitted to charge it upto 900-1000 mA but the phone was rather hot, I recall charging mine in an hour and a half or 15-20 minutes more, from 2-3% to 100% back when phone had GingerBread.

Nope, they won't do anything, but you can try all along if it's free service.

You can use 2.1A output chargers too, it is simply not going to draw all that but you might get the better on the go recharging while you're using the phone with heavy apps. Just think of the dual car chargers - they have both 1A (phone) and 2.1A (tablet) output. SatNav on 1A is zeroing or still draining your phone battery, while 2A can slowly charge it on the go.
You just give it a needed juice and if the discharge is so greater then recharge, there's not much you can do about it.
Call it a flaw, but Samsung did it cause of longevity of their batteries and li-ion technology.
That is why I indicated iCrap and BB - their fast charge is provoking rather fast discharge too cause the battery will not hold it. I have colleagues with BB who're charging in an hour but get their phones depleted in 3 hours of usage... I wouldn't want that from my S2 for sure. :good:

With stweaks you can let usb charge from 450 to 650mAh.

It doesn't matter what the output current of the charger is... the phone will only draw 650mA.
The charger I got with my S2 delivers 1A but my phone only draws 650mA. Actually the hardware doesn't support it.
IMO, 3hrs is pretty fast for a full charge.
Edit: Just noticed that Fevves already mentioned all that...
adressing sfafrorn
Some kernels have the Option to change the charge rate but even at 650mA the phone will get very hot if you are doing something on it while charging
Sandm4n is right :good:
