how to take good care of you batt

good read as it seems many still maltreat their li-ion
acording to old ni-cam myths

Also, make sure you read http://wiki.xda-developers.com/inde... revolutionary, comparative, numeric results!

I've always said this simple statement about LiIon: Charge early and often.
Do you need to plug the phone in every time you get off a call? No. Do you need to worry about it dropping below 80%? No. Just charge as often as is convenient. Sitting at a desk for a hour working on something? Charge. Driving for more than 15m? Charge.
I think if you obsess too much you might wind up with USB connector problems from all the cycles on the connector itself, but intelligent use of the above statement should get you the most out of your battery.

er.......what?

i believe that you have to charge your battery all the way full then use all the power until it dies then you can charge it back again
but not sure

conditioning the battery the first time you get a new phone also helps, alot of us just charge for a while them use it. all my phones i let them charge for a full 24 hours right after i get them

My battery only last 6 hours

Ugh, why don't people read the article BEFORE they comment?

Ehh, doesn't the charger uncharge when the battery is full? Like a safety thing?

Some articles say that one battery life cycle is used up everytime when a full charge is done. Other articles say that one battery life cycle is used each the battery is connected to the charger.
I have not seen one article that shows the truth with facts.

No offence but I always found this to be stupid reasoning.
What if you leave home with a quarter full battery and you get caught in the middle of a natural disaster (earthquake as an extreme example) and need to keep in contact with rescuers after being stuck in a building for 2 days?
Personally, I always charge my phone/laptop whenever convenient.

The only problem that your battery lasts only for 6 hours is due to too much charging...So when you will buy a new battery then make sure that only charge your battery when it will remain only 10%...And try to charge your battery with phone switched off..

Charge little and often, try to avoid deep discharge/charge cycles.
Back in the days of NiCd batteries there was the posibility of memory effect where if you didn't do a discharge/charge the battery wouldn't hold as much charge.
NiMH batteries do not suffer this, but discharge/charge cycles were required because when they started being used very few people had smart chargers so had to discharge to be able to time when to stop without overcharging, and also due to confused information pulled over from NiCds.
Top up charges are better for them too.
Lithium batteries also don't have memory effect, and are better off with top up charges.
Ask yourself this:
What would stress the battery more; running 1A through it for 10 minutes or 1 hour?
Also, as the battery discharges, its voltage drops so the current drain has to increase to compensate, discharging the battery even quicker (remember how capacity graphs drop off quickly?)
Say your phone needs 2W to run, with a 4v battery that's a drain of 500mA (P=VI)
When the battery has dropped to 3.5v then to produce 2W it takes approx 571mA.

batt problem
how to keep my batt good?

I've always just charged my phones overnight while I sleep. Never seen ill effects. If I don't make it home that night my phone still lasts through the next day.
It's not like that battery is irreplaceable. Go get a new one if your battery is nearing the end of it's life. By then you would have probably moved on to a new phone.

skimmed a few parts, but thanks for the read mate, learned tons.

as others allready mentioned, there are many different suggestions how to take care of the battery. I usualy reload the baterry only if the capacity is <= 5%, without unpluging it before it reaches 100%.

thanks for the info!

Defective thunderbolt battery?

Good Morning everybody!
I think I have a defective thunderbolt battery, sometimes when I pull my phone off the charger it drops to 95%. Funny thing this is not a everyday thing. Anybody having a similar problem like this? Sorry if this been discuss before. Have a bless day everybody...on my way to the office.

I have the same thing happen. There is something goofy with how the meter reports battery level. If you reboot your phone it drops even more.
Sent from my ADR6400L using XDA Premium App

Yea I notice that too. I seen my battery drop down 15 percent after rebooting. Is the battery defective? Or the phone is defective?

Bump charge it. Charge it all the way. Unplug, turn it off, then on, and keep charging.
Sent from my ADR6400L using XDA App

The phone/battery aren't defective. I have the extended battery so I never bump charge it, but he is right. Charge it up until your charging light goes green, unplug it and then turn it off. Once it shuts down, plug it back in and will now be orange. Charge it until it's green again. Sometimes it will take a few minutes, sometimes an hour. I'm also color blind so I can never tell whether that damned light is red/orange/green. >.<

is this all the time we have to do, I have the extended battery and it doesnt drop and I read about clearing the batterystats.bin but is this something we always have to do when we charge the phone? when I use the standard stock battery it drops with no problem

I didn't have any issues until I wiped the battery stats and now, my battery is constantly inconsistent. I would not recommend doing it as it has nothing but a pain in my arse since.
Have tried "bumping it" which essentially means to charge it to 100%, restart it, then charge it back again from whatever it dropped to.. Mine initially was around 85ish.. After a few "bumps" it crept up to 90 or 91 and then wouldn't go any higher. I charged it back to 100% and decided to follow the advice from another article which said to let it deplete to 0%.. In doing that, surprisingly it "froze" in a couple of places, I don't recall the 1st % but the 2nd % was definitely at the 28% mark. It literally sat there for a good 2+ hours with screen on max and didn't go down. Eventually it went down to 1% and I charged it back to 100%.
Issues still remain, wondering if I should've let it completely die out and force itself off?

Where do I get into CWM, to do this?

Thanks for your help everybody! I'm sorry if this is a dumb question...what is CWM? My device is stock.

CWM = Clockwork Mod.. Goto Market, download ROM manager, then you can flash CWM. Not sure if that'll do you any good if you're not rooted though.

why when I reboot my phone like 15% of the battery life drops I love this damn phone man...i cant put it down while im at work

The battery reading after reboot is wierd.
Yesterday I was at 51% and draining are at a pretty steady rate like normal. After rebooting, it showed 41% but then it say at 41% for AWHILE.. after like an hour, it read 40% and started discharging at the normal rate.

Thanks for the repost, I had skimmed this thread earlier but don't recall it being so detailed. Seems like the moral of the story is that while "bump charging" works, it's not really recommended as it can reduce the overall life of the battery. Wonderful, now I regret ever messing with the battery stats at all, although I can't say for sure I didn't have this issue prior to doing so.

My OEM battery wouldn't hold a charge even after charging it all day... I took it to the VZ store and they replaced it for free...... I also just bought the larger 2750 mAh battery.... works great!

[Q] full battery charge only reaches 98% after 8 hours

Hi i dont know why my battery isnt completely charging! or the battery charger info is broken! anyone else not charging to 100%?

It probably hits 100% then starts draining slightly to keep it from over charging. Mine gets to 99% then I unplug and replug it and it hits 100. But that has happened with a lot of devices for me.

Happens on my evo as well. You can get around it by flashing a kernel that does trickle charging which I'm sure we'll get for the tf sooner or later.

I would NOT use an sbc kernal on this battery, they are known to shorten battery life. Cell phone batteries are a dime a dozen, this thing is both non-user replacable and most likely not cheap.

Pretty sure its a lithium ion battery inside and you shouldnt overcharge those. You're best off keeping it between 30-90% and doing a drain and full charge once a month to prolong its life. The charger should stop charging when the battery is full on it's own anyways if you do leave it plugged in. I think it's a European law to have that as a safety feature, probably an American law for this too. So if the charger is staying hot a few minutes after your device has hit 100% charge, you've got a problem. Mine does get to 100% but yes it takes a while to top up, that's just the way these batteries operate.

Issues regarding battery charging, won't fully charge.

Ok, so I've been experiencing this for the past few weeks now, and I'm getting sick of it. I plug up my phone to charge it overnight, or just to charge it when I know I will be in a place for a while. After a while, the phones battery will say 100%. But when I take the charger out, the battery isn't fully charged. It IMMEDIATELY jumps down to around 40% - 70%. I can get it fully charged after unplugging and replugging the charger in, sometimes numerous times of unplugging and replugging. Also, my battery has died on numerous occasions on between 10% - 15%. I calibrated my battery the first day I got it (as a replacement) and got decent juice from it, a noticeable improvement from the old battery. Am I the only one experiencing these issues? Is there a fix for it???
*NOTE* I'm on my 2nd battery (replacement) and this is also a replacement phone. Also running GummyCharged 1.8 GBE on EP1Q, RFS, w/Minimal Gummy theme, if that matters. Also, its not just my phone, my wifes Charge phone has the same setup and it does it also. So it may just be something wrong Gingerbreak. Never did it on FroYo. Gonna Odin back to FroYo and report back.

This is because you cannot leave the phone plugged in to charge for an extended period of time. Once the battery reaches 100%, it stops charging. It will start charging again later, after the percentage goes down to a certain set level. This is why you have the huge initial drop-off after taking it off the charger. If you want to leave the phone plugged in for an extended period of time, turn it off and plug it in to allow it to charge, then it won't discharge as quickly. Otherwise, this is normal behavior for all android phones, and trying to make it so that the phone stays at 100% full charge is bad for both the battery and phone.

I've been having some strange problems. My phone will die with between 4-8 percent battery left. I can turn it back on and once it drops another percent or two it will turn off again. I have calibrated it and my battery life is good but this is a strange issue. Upgrading to rc2 today.

I have the exact same problem. It will just go from 50% to 100% in a second and then unplug and plug back in to make it work. i haven't been able to figure it out either. 2nd phone and 2nd battery as well with same issue. I guess it has to do with my habits somehow.

I believe the use case he is suggesting is a little different than what you are describing. When the phone is plugged in at say 12%, it charges for a while and gets to say 63%. At that point it jumps to 100% immediately. The phone must then be unplugged from the charger and re-plugged in and then it will continue properly to 100%.
Hopefully that is a little clearer.

I mean, usually I turn it off to charge. And I have that No Moar Powah app installed. So I set it to reboot at 100%, it does and when I take the charger out, it immediately drops to between said percentages. almost like clockwork. Very annoying. I understand what u mean Imnuts, but my Vibrant, HD2, or others never experienced this issue. Also, my first Charge, would keep a charge if I left it on the charger once it hit 100%. Maybe an issue with the charger itself? A Verizon rep told me to bring in the charger itself if the issue persists.

Almost exactly my issue. I'm not understandings what the problem is. I'm assuming u have that issue also???
Sent from my SCH-I510 using XDA Premium App

Hmm i have the opposite of that problem every time i unplug my phone from charging overnight the battery meter would always read 100% never below that.
Also does anyone know which battery meter i should follow for battery calibration? The battery meter in the status bar, the battery level in system settings/about phone/status, the battery percentage at the lock screen or the battery meter on the screen when the phones off? They're all giving me different readings for some odd reason.

Sometimes I get that too, but for the most part, its the false readings from the lockscreen, and the about phone settings. I may send off for a new phone, run stock for a few days to calibrate my battery then root on a full charge.

Well I went back to FroYo GummyCharged v1.9 and lo and behold, the charging issues VANISHED. Charged my phone overnight last night and when I removed the charger, 100%. No drop immediately back down to 56% or some weird number. Maybe its a Gingerbreak leak issue. I've noticed that it only happens to my phone on Gingerbread. Also must mention, my wifes phone does it also. She's on Gingerbread. She complains that I broke her phone lol.

The mis-information in this thread regarding Li-ion batteries is getting out of hand.
I think many of us are thinking about ni-cad batteries in which all the "bad" things we are talking about in this thread apply.
for a Li-Ion Battery, there is no "memory" effect. this means you can charge it at any point during the discharge phase. You also do not need to allow the battery to drain fully and charge to full to "condition" the battery. Li-Ion batteries can be charged at any point up to any point (from 30% to 70%, then 50% to 90%) and it will not effect the batteries performance.
Li-Batteries also do not suffer from overcharging. The charging circuits in cell phones will charge the battery until it is full, and then trickle charge from then on. And because Li-ion batteries do not have memories, this type of charging will not effect performance.
Li-Ion batteries can only be charged a finite number of times. However, the number of times does not translate to the number of times you happen to plug it in. The batteries have a rated number of "charge cycles", this is when the power from the battery has been exhausted and then re-filled. If you always charge your battery at 50% - 100% then every 2 charges you are using 1 full charge cycle. The batteries in the charge are 1600mAh and have approx 500 charge cycles. if you discharged and charged your phone from 0 to 100% every day, your battery would last 500 days before it would start to suffer from poor performance.
the OP in this thread is having software related issues related to the phone mis-representing the correct charge level of the battery, and then stopping the charge cycle prematurely.
Remember, it is perfectly OK, and expected of you to charge your battery as many times as you need to. Keep the thing on the charger any chance you get, it is not going to hurt it, its designed to be used that way. This is why Li-Ion took over as the battery tech of choice compared to Ni-cad.

This coming from a person WHO KNOWS WHAT HE IS TALKING ABOUT is very beneficial to us. Knowing that there is no way to actually "condition" a Li-Ion battery means that us who are actually suffer from poor battery life either have defective units or defective batteries. I hear of this miraculous 2 day battery life, yet I struggle to get thru a full 7 or 8 hrs with moderate usage. And this is a replacement unit AND battery. None of my other phones had that issue of immediately droping percentages like that, so I figured it was a software issue, that's why I went back to FroYo to test it out. Seems I was right. Gingerbread has a software issue that keeps the battery on some phones from reaching a full charge. Also my phone would be boiling hot during the charging process. Since reverting back, I've had no issues. Thanks for the insight. Coning from a knowledgeable source, it means a lot. Thanks!!!

How to make your battery last longest?

So I just got my galaxy s3. I haven't turned it on yet. But I heard that you were supposed to charge it fully and then let it die. Then charge it fully again and then start using it. That when. Doing this you will optimize your battery so it will charge faster, hold a charge faster, and just last longer.
Is this myth or fact? And if fact how do I do the steps so I get it right?
Thanks for the help and sorry for any mistakes it was typed on my phone that has aa small touchscreen.

Now is this ALWAYS the case?
To clarify what I am asking I am saying does it always harm the life of the lithium ion cell by letting die fully? Like even after 6 or 8 or 12 months of owing the phone (or any device), not just one the first charge. This could be very useful for further reference...:good:

There are some things can help increase life of litium batteries. First, don't let it go down to 0% as mentioned, keep not lower than 50%. Once per month it is recommended to discharge battery to 0% and then charge it to 100% again for device callibration.

This is a good question. I always thought that by discharging and charging batteries at full cycles, you would make their total useful life last longer.
In fact, this happened to me with a notebook, which I used to play with and charging at the same time. In the end, the battery lasted for a few minutes and I had to sell it.
But in all: is this really true? I would also like to know if is truth or myth.

This happened too (as funny as it is) my grandma. She would ALWAYS have her little nnotebook plugged in and eventually it drained. I found out because one day I took it off the plug a d it died while I was on facebook after around 7 minutes.
So I bought a new battery and now she charfes iit and takes it off the plug to use it and twice a month she lets it die and it has worked

Sir i just want to ask If we charge our battery even if its above 20% or if the battery icon is not yet colored red will it affect our battery life in the future? Or we should only charge our battery when it is below 20-15% ?

So I just got my galaxy s3. I haven't turned it on yet. But I heard that you were supposed to charge it fully and then let it die. Then charge it fully again and then start using it. That when. Doing this you will optimize your battery so it will charge faster, hold a charge faster, and just last longer.
Is this myth or fact? And if fact how do I do the steps so I get it right?
Thanks for the help and sorry for any mistakes it was typed on my phone that has aa small touchscreen.

It is true if you have a phone like Nokia 3310 if you do not have a NiMH battery do not do that you will lose time also you do not need to "format" a Li-Ion battery
read about lazy-battery effect on Wikipedia

rooting you phone to underclock/undervolt should also help out battery life pretty significantly ^_^

Lithium ion cells do not suffer from the "memory" effect as older rechargeable batteries. You do not have to let the battery run all the way down then fully charge it again to get the best performance that way, that was for the older types of batteries (again so you wouldn't get that "memory" effect) matter of fact its rather harmful to the battery to run it all the way down.
Charge the battery as often as you want no matter at what level it is. If you are going to do some high power **** (play a game, watch a movie) then plug it if if you have a charger around. The longer the battery stays at a high level the better for it. Try not to let your battery run your phone at a low state (charge it asap). Its ok to leave it on the charger even after its fully charged. Your phone and charger are smart enough to know when to start/stop charging the battery. This will ensure a long life for your battery.
...as for your phone...simple rules...if you are not using it( DATA, WIFI, GPS, SYNC, BLUETOOTH) then turn it off. Screen is the biggest battery drainer...KEEP IT ON AUTO!...darker themes really help alot...make your screen go off at 30 sec. or less. Have fun with your new phone homie.
