[Q] Getting the most out of new Samsung 2000mAh Bat - Galaxy S II Q&A, Help & Troubleshooting

Hi
I just received my new 2000mAh Samsung replacement battery. When I say "getting the most" from it, I mean get the best performance and prolonging it's life. Now I've read about many myths regarding Li-ion batteries. Some say that upon first use you should do a full discharge and recharge cycles for at least 5 times. Some say that you should never allow it to discharge below 50%.. Some recommend to charge it only when the phone is in shutdown... Some say you should not charge it all the way to 100%...
What do you guys say based on your experience? Does this bat need a full charging cycles? What is considered a full cycle? Is anyone here using this bat? Did you notice any major difference compared to the stock bat?
Thank you for your cooperation

Mate there are tons of information regarding battery life here on XDA. In most cases it depends on your ROM and Kernel as well as usage. You can do a search but for starters you can try here http://forum.xda-developers.com/showthread.php?t=1909996. I personally have the 2000mAh battery and yes there is a very noticeable difference compared to stock battery. It is probably best to fully charge your battery and let it run all the way down for at least 2 cycles. If you want to get more technical and tweak settings you can visit the thread I posted or do a search if this is not what you are looking for.

Just do what I do, don't care. Of course I don't want my phone dead around noon. That's why I use betterbatterystats, I just look for wakelocks and processes which eat up battery. That's it! It obsesses you if you always want to improve. Getting rid of wakelocks and stuff is all you want. Trust me, focus on not caring about the battery, find a ROM you like charge cycle it a few days and battery is fine.

[Q] Will an everyday battery charge harm my phone or my battery?

Hello dear members
I'd like to ask if an everyday charge will harm my battery.
It's my first week with my phone, and I can't keep my hands off it
As a result, battery runs out every day!! So I charge it...
Will something happen to the battery?
thanks in advance
This phone has a litium ion battery. They don't have a memory effect but in the first time they need some time to become the full potential. So it doesn't matter if you charge the phone every day.

Thank you so much!!!!
It's a relief
To maintain better battery life it might be a good idea to make sure that u dont fully drain the battery
That shouldn't be a problem the most battery's should have electronic inside to prevent this but I can't guarantee it. You can read also the Wikipedia article about lithium ion batteries it's quite interesting.

It is better for you to charge daily and often when the battery still has charge and not leave it until the battery is totally flat.
Thanks so much everyone Point taken
I'll never let it fall under 10%.
Well, Battery is average. If it weren't for the 2.3.3 bug, it would rock! In order for it to be normal, I keep ****ting Services.(under Services menu) like Voice talk, SocialHub(which drains a lot of battery) etc
Anyways, thanks to everyone

Isn't it actually opposite, I mean somewhere I heard that if a Full charge is given after a Full drain then the battery gets conditioned (optimized I think), can't remember the source but I do remember the fact.

I'm glad this thread exists. I'm so used to running a battery down to the minimum before charging it that I probably would have been in that habit for my SGS2. I'd actually come here to ask the same question now I've been through my first four or five "full" -> "red" -> "charge to full while off" cycles.
Is it confirmed both from the SGS2 & LION technology point of view to now keep it charged up, even if using only half/quarter charges etc to do so?
My battery is giving me around 40 hours a time so not too bad but I'd like to keep it running as well as I can.......

Nope. Li-ion batteries these days prefer constant top-ups and full drain actually kills it faster. Totally opposite of what people have been taught over years of NiCD battery use that I've got friends who absolutely refuse to charge their iPhones unless it's at 10% or less. Their loss.

No that's only good to do once in a while. Full discharges daily put stress on the cells and wear out li ion batteries quicker.

Yes it's common for all lithium ion batteries to charge as often as possible. Its true for all phones on the market today and quite a lot of discussion on this is all around the web.
Also a replacement stock battery for any cell phone today is around 20 dollars, so really you can't do much wrong since its so cheap to buy a new OEM battery replacement.
Thanks for the replies. I think this will catch a few people out so hope the thread doesn't get missed amongst all the other battery ones!
Looks like I'd better change my charging habits!

[Q] Control charging

Hello, is there a way to have the charger connected but only use it as an external power source like on laptops without charging the battery? I use my tablet often near the charger and don't want to start the charging process 5 times a day.
Thanks!

I don't know, but I'm curious why you want this? Did they put a Nickel Cadmium battery in your GT10?
I want this for the same reason as on lenovo laptops. With this feature you can save some charging cycles and the battery would last 1+ years. On my dell with the charging plan same as my p7500 the battery was dead (less than half capacity) after 10 months. And I do not necessarily need my battery charged to 100% all the time..

No it's Li-Ion, don't really understand why you think that Li-Ion is not impacted at all...

Sorry, I'm just having a bit of fun messing with you, but you need to update your understanding of rechargeable batteries.
Ok, no prob I realized that you don't know the answer, can you at least share your opinion why this looks like an unnecessary thing to you and prove it? (link)

I think that slack04 is refering to the properties of Li-Ion batteries. These are very different from the older technologies like NiCd or NiMH.
In short ... Li-Ion batteries realy love to be charged all the time. Keeping them attached to a charger all the time or multiple small periods of time will not hurt them.
There are only a few things that will realy hurt Li-Ion batteries:
- time : Li-Ion batteries degrade over time, even if they are not being used. You can expect a Li-Ion battery to work OK for about 2 years. So, never buy second hand Li-Ion batteries or batteries that have been stored in a shop for some time.
- heat : do not keep a Li-Ion battery in a hot place (like your car in the sun) It will severely reduce its usefull lifetime.
- undercharging : If you let a Li-Ion deplete to a too low level, it can be damaged beyond repair. But, our tab will turn itself off way before that low level.
So, just let it charge itself as much as it can.
This is not true for the older technologies. I think that's why lots of people are still thinking that very controlled charging cycles will prolongue the lifetme of their batteries.
Cool, so we can use tab connected to sector all long as we want with ion battery! ?

Thanks a lot for the link, it's interesting reading that the best would be keeping the battery at around 40% charge.
BTW is it a Li-po or Li-ion battery in galaxy tab 10.1?

Read it again, and don't post stuff that will confuse new folks. Here's a quote from the article:
"The smaller the depth of discharge, the longer the battery will last. If at all possible, avoid frequent full discharges and charge more often between uses. If full discharges cannot be avoided, try utilizing a larger battery. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles other than to calibrate the fuel gauge on a smart battery."
slack04 > I've read the article very well... and I feel that your posts don't add that much value to this thread. maybe you could read it again as well.
Please check the table from wiffeltje's link. It clearly states that at 25C at 40% charge the yearly loss in capacity is 4%, and at 25C 100% charge level it's 20%.

I don't want to make it even more difficult, but the table you refering too deals with 'storage'. That's a good table to follow if you need to store your device for a couple of months without use. Then it's best to have a 40% charge.
For normal use the simple rule is : keep it connected to the charger whenever possible.

[Q] Low charging current?

i just got a new momax 2700mah battery still fresh from the box and put it on my phone.. initial battery level shows 22% but then after a few moment it jumps to 62% and stop charging afterwards.. i check using battery monitor app and it shows i only got about 100ma of current even though im using an AC charger to charge..
what should i do now? im puzzled because i can't even know what is my current battery level??
Try to charge it for couple of hours

Hello,
You need to let him charged during few hours and after calibrate your battery stats with "Battery calibration".
Battery apps on the SGS2 only give a rough estimate of battery available at any given moment (a limitation of the hardware).
Non-stock batteries probably don't have the fuel gauge chip stock batteries have, so any reading you get whilst using one of these is probably going to be even less accurate than using a stock battery.
Obviously using non-stock/genuine batteries is a case of caveat emptor.

i see.. no wonder the batt percentage suddenly rides a rocket
it charges normally now but slightly slower than stock.. definitely
so any battery apps are rather useless when using an extended battery particulary on S2?
They're not useless, but there's no way to absolutely 100% accurately measure how much juice you've got left, even with stock batteries. The numbers reported by battery apps are normally 'close', but you can sometimes see all kinds of weird results like the ones you saw with that battery you just got.

ok, i get it.. but would it affect to the actual battery life?
i mean battery life should scales according to its battery capacity right? even though the phone thinks that it still running on stock battery..
No, it shouldn't have any bearing on the life of the battery.
Yes, at the end of the day you'll get the right 'capacity' regardless of any inaccuracy shown by a battery app at a given point in a charge cycle. For example, I have a 2000mAh Samsung battery, and my testing shows I do indeed get on average around 20% more juice out of it compared to the original 1600mAh one that came with the phone.
Tho non stock batteries are notorious for often not having a capacity the same as what they're advertised at. I bought a 3500mAh non-Samsung battery in December, tested it out for two weeks & found it was only roughly 1800mAH. It also used to get really hot (45°C) when charging so I took it back to the place I bought it from & got a refund then bought the Samsung 2000mAh.

Will check for improvements soon after 2-3 cycles..
Wait, what? So ur saying that the bigger the capacity the more inefficient it gets? How did you know the actual capacity of the battery ur using?
Sent from my GT-I9100 using xda premium
I didn't know the actual capacity for certain because I don't have the equipment to test that kind of thing, but my testing gave me around 10-15% more juice than the stock battery so I figured it was around 1800-1900.
Not exactly scientific, but after two weeks and a bunch of charge/discharge cycles, it was nowhere near the 3500mAh it was alleged to be, so I returned it. For me, I'd rather stick to a 2000mAh Samsung battery which was the same price as the genuine 2000mAh battery (~$40). I get fantastic battery life as it is, and 2000mAh is plenty for me. Plus I have the original 1600mAh which I store/keep charged @ 60/70% as a spare which I can charge to full quickly if I need it.

[Poll] New device: Discharge or charge first?

I know that many people will tell me that with new batteries it doesnt matter, but I need to know anyway, because nobody seems to be really sure.
Think of this as a research.
When you buy a new phone, what do you do first: let it drain the initial battery charge or fully charge right out of the box?
How is your battery life (considering what you did)?
Thanks.-
I usually drain the initial charge
Sent from my amazing Nexus 7 using xda developer's app
I usually charge it and then drain in on the first use. It doesn't have an effect on the batteries, its more of a way to calibrate the device to its battery. But I don't really think it makes a huge difference. Your battery life early on is usually bad due to all the time you spend setting up a new deice.

[Q] Any way to ACTUALLY calibrate a new battery?

Hello
So my GS2's battery was seriously getting crappy, and I ordered a new original battery (more expensive, but I really wanted it to work properly). Before the replacement, it was all over the place, and I think I may very well have a phone that's seriously confused about its battery options.
Thing is, after the replacement the phone isn't charging the new battery properly (AFAICT). If I'd have to venture a guess, I'd say it charges it to 33% and then it states 100% full.
So, I get just a handful of hours of regular on-time with this new battery. Sometimes the phone hard-dies when saying about 50% remaining, other times it actually says something like 2% remaining, then dies, but still awfully far from logical, considering the fresh battery replacement.
I've searched for how to calibrate this thing, and most results simply recommend the "fully deplete, then fully charge, extract, reinsert, etc." method.
However, this does nothing to help me.
I read somewhere that for some custom ROMs (Dorimanx kernel?) you could do a more "explicit" recalibration, but I'm not sure if that'd work — as I'm on ParanoidAndroid ATM, and here I don't have such option.
So... Does anyone here know of any more "legitimate" way of recalibrating? I really don't want to buy a new phone, as these days I don't see any phone I really want to buy...
TIA,
Daniel
new batteries require a few charge discharge cycles before they reach max capacity, you may need to leave it on charge for longer than the "charged" info appears.

Thanks, Sparks, but I've already done this many times. I've had the battery for a couple of months now, but I really need to figure out how to calibrate the phone so that it starts behaving "normally" with my new battery...
Let it die, juice it up while it's off, take the batt for 90 sec when it hits 100% and put it back in?

No. The whole 'calibrate the battery thing' (and the apps that claim to do it) on the S2 is Kool Aid.

Something definitely needs calibration, and yes, of course it's not the battery itself when buying a fresh original battery does not fix one's battery problems, it must be some battery controller somewhere. I just started a new job, and my CEO has a Galaxy S3 which started having battery troubles. Like me, he replaced the battery, and like me, nothing changed.
In the meantime, my S2 died completely, so problem "solved" I kinda feel retarded for planning on buying a Note 3... Probably ought to run from Samsung devices altogether...
