Multiple Batteries? - Captivate Q&A, Help & Troubleshooting

I have two batteries for my Captivate If I let one of them run down, then switch it out for the other that isn't fully charged (its somewhere around 60% or so), do I risk having battery calibration issues?
Thanks!

yes. you risk battery calibration issues even if the other battery was fully charged. not all batteries are created equal. both batteries could say they are full but still be off by a couple percentage points.
that being said the issues shouldnt be too severe perhaps slightly more drain...but who cares you have 2 batteries so you'd still come out ahead

I don't believe your battery calibration would be that off swapping between two same size batteries. I could see there being issues if you go from an extended battery, to a regular one.

I have five batteries and swap between them all the time. (I bought them while running CM7 ) I always shut-down, and then swap in a fully charged one. I have never noticed an issue.

[Q] When should i charge the battery?

hi!
guys, when should i charge the Galaxy S battery to maximize his life?
In my old phone, i only charge it when the phone shuts down himself. It can run for 7 days with no problems until i need to charge again.
Should i do the same thing with Galaxy S battery?
Well, when i need to connect the phone to the PC using USB cable, it will charge anyway. Is it bad? Should i do it only when i know the battery needs to be charged (when it has low battery)?
any time you want
it should always be topped up, there is no memory effect
Some people say that we should charge when the phone has 25% or 30% of the battery. And every month we should make a complete charge and discharge.
Is this a good method to keep the battery ok?
best way is to cycle through 2 or 3 batteries
charge them full
then use them down until you get the warning, and change to new battery pack, then take the used battery to the charger

Although I don't really have any definite sources to back this up, I've read several places that Li-Ion and Li-Polymer batteries can (and even should) be charged as often as possible. You should avoid letting them run flat, apparently.
What is certain though, is that they themselves have no memory effect like NiCd and NiMh batteries have.
our SGS will nag you to death as soon as it reaches 10%, and it will constantly annoys you to charge the battery at 5%
so, no worry about running flat
Technically to maximize the life (ie. capacity) of a Li-ion battery you should charge to full when it gets down to 40%.
The cooler the ambient temperature the better - A Li-ion battery operating at 25 degrees C will lose 20% of its capacity in one year. Higher temperatures drastically increase this degradation.
Given that most people will move to a newer phone after 2 years or so, and spare batteries are cheap as chips, it doesn't make a whole lot of difference.
So, people say that we should charge the battery when it has 30-40% of the capacity.
But what is the thechnical explanation?
Sent from my GT-I9000 using XDA App
that's exactly what i would like to know as well at 30%-40% will make the battery totally useless if that is true
might as well take the phone with a super long extension cold with you if that were true
LMAO

I don't think that would be the best strategy, AFAIK (and read)
Li-ion packs prefer more frequent charges, even if after partial discharges, than full charge-discharge cycles.
Its also not good to store the pack fully charged. Best to store at 40% charge.
Following these 2 concepts, I imagine its better to charge the battery as often as possible, like every day, than to let it discharge until you get the warning.
Also, if you cycle through several packs, letting each one discharge almost completely, then charge it fully and move to a different pack like you suggested, that means you will be letting the battery unused at full charge for a longer period (the more packages you use, the longer the pack will stay stored at full charge).
Thats how I understand the behavior of those batteries. Just my 2 cents.
Paulo
I will say what the first reply said, charge as often as you feel you have time. Do not wait for any percentage of drain. There is no memory effect and yes about once a month do one full uninterrupted cycle. The point of which is to let the device's power management recalibrate where 0 (or thereabouts and 100% of the current fill are.
Cooler is better, this is also true.
All educated advice on Li-Ion batteries is that they remain healthier for longer the fuller they are, but the chemicals must be exercised occasionally, thus the full charge cycle in one go.
One charge cycle also actually counts over multiple charges, and not just uninterrupted ones. You can drain then charge 25% 4 times and that is counted as one cycle for these batteries.
I have always stuck to this advice since I learnt of it several years back and I find my batteries work better and longer than many people I know (who stick with drain, charge methods (lack of updated information).
i agree with nailerr
Simply charge it when you need to. It's better to have a fully charged battery when you need it, than run out of battery when an important call is coming through
So, the main reason to charge it with 30%-40% left is to avoid the battery heat too much?
I found this: h**p://batterycare.net/en/guide.html
It says more or less what you guys said here.
But you need to know that i always charge from 0% to 100% my old phone. It is 4 years old and it has no problems with the battery. It can run up to 7 days without any charge... Looks like charge it that way is not so bad anyway i guess...

Two batteries with Darky's Rom

After flashing the recommendation is to recalibrate the battery, or let the phone do it over several charging cycles. Any idea how this would work using two batteries?
I have two genuine SGS batteries and swap them over when necessary. Does always keeping one charged and swapping mess the stats up.
I am in the same boat. v9.5 ROM and two Samsung batteries. Swapping them does not seem to make much difference. I did do a few full discharge and charge cycles to begin with with the one battery. Getting the same run time out of each battery now.
No real difference if both are fully charged .
The rom drains the battery not the stats the stats play less of a part than people think .

3500 extended battery decline in performance

I purchased the 3500 extended battery about 4 months ago. It was a great battery. It lasted me all day & then some off a single charge. Now it's not lasting as long as it used to. I'm having to charge in the middle of the day now. I put my original OEM battery in, & I'm getting better performance from it than with the 3500 battery now.
Anyone else experiencing less than stellar performance from the 3500 battery after having it for 4 months or longer?

I have the 2150 OEM, I can only suspect some reasons why
1) Cheap battery that does not hold charges well
2) You are draining the battery down to 0% a lot, killing the ability for it to keep a charge
3) Your phone is not calibrated properly so it shows it is charged to 100% but in fact it may have only charged it much lower

1) It's a Seidio brand, not some knock off, so it should be of good quality. It's been working fine up until the past month or so. I've had it for over 4 months now.
2) I've never drained the battery down to 0%. Contacted Seidio and they suggested that I let it drain to 0% for the next 4 to 5 charges, along with charging it an additional 2-3 hours after a complete charge. I'll see if that helps.
3) I've always had to bump charge it. It helps in making it last longer.
I don't think bump charging is helping the longevity of your battery. Not saying it doesn't last longer on a charge, but that it isn't good for the battery's overall lifespan.

Draining all the way down and overcharging it are the biggest ways to kill it off. The Seideo and most other batteries I think have a fail-safe for draining it all the way down, cutting it off early before it actually does.
This article is pretty helpful about your battery, if you haven't had the chance to read it, it may benefit you:

Bump charging did it.....
Where's ma rosie at?
I have been using the 3500 for about the same length of time you have been. I haven't really noticed a drop off in performance. Maybe a very slight drop off.. not much though. Still could get 2-3 days use on one charge if I wanted to.
I have the same issue with my 3500. I will try to re-calibrate it.
4 months seems to be pretty quick for a decline in performance like that. I would press Seideo to replace it.
You can try resetting the cells to how they were when it was brand new. All you have to do is completely deplete the battery of all charge (so it wont even turn on) then short it out with 3x the voltage (a 9v battery should work, make sure to keep the polarity the same) and fully charge it again, then it will be like new!
My dad (who is an electrician) found a guide for this on ebay and bought it just for the hell of it to see if it worked. We tried it on a battery I had for an LG VX8300 I had at the time and it worked beautifully, I've been doing it ever since!
I have no idea how this works, all I know is that it just does.

When ever you get a new battery you must condition it, exactly as sedio said full charge it, then drain fully 5 times. It makes the battery last much longer

I got some 3,500mAh cheapies off ebay about 6 months ago and they are holding up just fine. I always run mine down to about 5% then fully charge. I bump charge them about once a month.
Well of course... After I'm pimping how great these batteries are, one quit working! My phone would just shut off with a light tap against something so I pulled the black sticker off of the battery, pulled it all apart, found the loose connection, bent the tab to make better contact, and put it all back together. All is good again.
I recently purchased this same battery read tons of good reviews not sure how i feel about the bump charging after reading the article that was within this thread but all in all it is a giant leap beyond the stock battery now if i could just find a case that would fit around it
To the OP. If youre running a kernel with SBC (Superior battery charging [trickle charging] w/e you wanna call it) they're known to reduce your battery life. also you may wanna charge the battery to 100% then wipe the battery stats on your phone.
I have the same battery and I've found that the phone has trouble reporting the percentage correctly. It tends to make jumps of about 5-10% instead of a steady decline. I switched to the original battery and it did not have this problem. I've also noticed that clearing battery stats several times helps (most of the time). As far as bump charging goes, it's perfectly fine to bump charge these batteries. The worst thing you can do to them is discharge them all the way.
Clearing the stats and cycling the battery through the phone a few times should fix that. It does that (big percentage jumps) when it's poorly calibrated.

3500mAh battery

Hello, I recently purchased the 3500mAh 3.7V extended battery for my dinc. Can someone tell me what voltage I should charge it up to? I am not seeing amazing results, so I believe that my battery is not completely calibrated. I did run it through multiple complete uses (fully charged, to drain, and repeat) so I don't know what the problem could be. Thanks.

What were you expecting for battery life? Depending on the brand it may not be a real 3500mAh battery. One full discharge and recharge should be enough to calibrate the software though Li-Ion batteries have no memory in them. Check this out. It mentions extending the life on the battery but is still interesting stuff.
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries.
In fact that whole site has a lot of info on batteries.
Hey tiny. Well, from what I was reading about this battery, users got two full days with heavy usage (they described heavy usage to be streaming music, surfing the Web, testing, playing games, etc.) but, this is what I get, and it's the best I got (3 hours display,half an hour talk time). I even went down to gb to see if it would be good, but I didn't see much of a difference. And I did look at battery university a bit, but I didn't delve into the material. I'll check that link out.

Wow, that's pretty abysmal for a 3500mAh battery, especially in a lower consuming device like the incredible. How does that compare to your stock battery? It should be at least 70-80% better assuming that it's not really a 3500mAh battery. It may be a false claim that it's 3500mAh from the makers. I think 4 hours screen time on 3500mAh should be more reasonable for about 35 hours total time. I usually get about 1-3 hours screen time over a period of 10-30 hours total on my Galaxy Nexus. On my Inc on CM7 with stock battery my usage allowed me to go up to 30 hours, usually 20 on a charge with 30% left I think but it's been a while and I don't know the screen on time. It might have been about 2 hours.

Yeah, that's why I am worried. And actually, my stock battery usually have me like a day with good use. When you put it in perspective, my 1300mAh battery gives me about 67% of the battery life that I get from a 3500 mAh battery. Is there any way I can measure the power of the battery? I take physics, so even finding a way to calculate the current, voltage, and/or resistance of the battery would help.

Check batteryuniversity.com, they have a link for calculating the actual capacity, or if you know your model which you should you can Google for actual capacity. Someone probably has posted capacities of a battery.
just going to add that in my experience(I have 3 Dincs), just a 3500 mah battery isn;t going to give you amazing results on it;s own. power management on the Dinc requires some attention. i find that charging the battery in the phone doesn;t necessarily yield a full charge, especially if you are charging it while the OS is loaded(topping it off). so my strategy has been to run my batteries down to empty,replace with a fresh one and charge them in an external battery charger-but not just any charger but a RAVpower universal charger. I have an "official" Seido charger and that doesn;t charge my batteries fully either even though it thinks it has by showing a green LED. I know some people will say that batteries shouldn;t be treated like this and that they don;t suffer from memory effect so you are free to not do what I am doing.
the biggest things that use up the battery is the 3G radio and the Display so of course if you are just using your phone to do stuff non stop of course you'd be lucky to get 4-6 hours of usage. Even if you have your phone doing useful stuff over wifi like checking for email in the background, it does consume battery. but with my phone in Airplane mode(like overseas where I would have no 3G or Wifi), I;ve gotten a couple of days of Standby time.
other stuff I have done is remove any apks in memory that might be consuming cpu cycles and memory. less is more on a limited platform like the Dinc. biggest cpu hogs on my phone believe it or not is Facebook and Amazon App Store(my guess is that it;s periodically checking my licensing for some apps that I got from them). it;s not uncommon for me to boot up the phone and for the battery to go from 100% to 90% in 5 minutes as the phone is initializing and doing whatever it;s doing. then slowly deplete from from 90% to 80% in 8 hours or so.

Your battery gauge is lying to you (and it's not such a bad thing)
So, I looked through all of battery university, but i still have 1 unanswered question. The website states that most Li-ion batteries should be charged to a mximum voltage of 4.20 V. However, does this apply to all batteries? I mean, my extended battery is a 3.7V battery. Was the htc dinc original battery a 3.7 v battery? If the voltages are different, then wouldn't the 3.7V battery need to be charged to a higher voltage so that the potential difference would equal that of the original battery and thus store the same charge? (theoretically)

Is the quick charge harmful?

Hi, I'm using my samsung phone with quick charger, however, I saw some people discuss that quick charge is harmful to the phone, is that true? anyone can confirm about this?

I can't say that quick charge is harmful however what is usually not a great thing to do is to stick the phone on the charger all the time when there's plenty of power left. Like charging it from 80% to 100% is just wearing on the battery life faster and causing it to use an extra cycle.. Think of it like this say the phones battery can ONLY be charged a total of 100 times and that's IT no more it's dead after the 100 charge.. if you stick it on the charger at 95% and charge to 100% well now you just lost a cycle and you only have 99 charges left.. Wouldn't it have been better to use the entire battery power until it shuts off and then charge it?! Doing it this way actually extends the batteries life and keeps it working a lot better than constantly doing small charges.

Ive always been taught that the faster u charge a battery the less charge it holds. And decreases the life span faster. That slower is always better on lifespan.
The added heat from quik charge also puts strain on device if being used at same time.
Just my opinion
Ive googled this and according to some psyhics, it doesnt matter how fast the electrons get to 3,000 mah. What really harms the battery is getting above 90% and below 10%. Everytime you get to 100% it counts as an cycle, and batterys have a limited life cycle. My orignal barttery went bad after 11 months...degraded from 3000 mah to 2,200. I manually replaced the battery myself

i just personally dont think its good on them to quickly dump voltage to them either
Not sure it will harmful to the battery life span, but sometimes I charge my phone to 100% and continue, so this will also harmful to battery?
You can just not use your phone battery at all. Once lithuim ion batterys reach 100 thats it, they then drain from your electricty So by turning on your power case when uts at 100%, the phone drains from the case. Of course if your using like an 1amp charger, theb battery will drain if using while plugged in., because the screen is eating more energy than the 1 amp can provide
Batteries are cheap....replacing them isn't that difficult. I got 20 months from my original battery(always fast charged).
If I get the same from the replacement then it's all good.
Use the phone....that's why you bought it.

Yes, forcing a lithium battery above it's operating voltage, something like 4.7v with a 5v to over come is ok. But 9v!?!? That's degraded it's performance. In the great scheme of things does it really matter? Probably not, chances are you will get a new phone in a year or so anyways and thats about when the battery fails.
Oops
I don't want to change the battery, and for now, more and more phone come with battery non-removable, it's not a good choose to change battery.

It's difficult? Could i ask you which battery to buy and where you bought it?
Its only hard if u want to keep your glass back. I tore up and shattered mine and dont care because my phone is always in a case, so youll never see the back. Got the oem battery from ebay for around 10 dollars. Then its just a matter of taking out all the screws, connecting the really small connector, and screwing back tightly. Like you need put pressure on screen when putting back together because for example volume down button might not work if press 2 lightly
It's easy, use a heat gun and the simple tools. Took me 20 mins and I didn't break anything. Just bought the battery off eBay
