Battery question - General Questions and Answers

hi guys
I have always been wondering what to do with the battery after purchasing a phone. normally its about 50% charged and im not sure if i should let it drain normally or just charge it up straight after i get the phone out or something?
i know that with the old batteries u supposed to charge the 1st time about 12h but dont think its a way to go in the later batteries?

Same applies mate, its always best to charge battery fully before first use to get full potential of battery

fair enough, thanks mate for a quick reply

for lion battery u have to discharge fully for 2 to 3 times initially to get max.. performance

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.

that would kill the battery life fast, yea u wont run out of battery soon but keep it up and ur battery is gonna die on u after talking for 1hr

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

This is the exact opposite of what this article says.

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!

[Q] how to make the battery charge life longer

hi friends
i wanna ask a question about how i can make the battery charge life longer?
thanks

It depends what type... I know one where you'd almost have to drain it but not all the way then fully charge it would make the battery life longer than having its life cut short.....
Sent from my S using Tapatalk
Try this technique which I used on SE XPERIA X10:
Charged the phone to 100% and while still plugged to the charger remove the battery wait 5 seconds put the battery back unplug the phone switch it back on and plug back into the charger. Ur battery should now show 88% charge not 100%. will wipe the battery stats as well when I will fully charge to see if it makes a difference.
Need to fully discharge the battery at least once a month until the phone off .. then you load up to 100%, and doing what was said above, remove the battery, and turns the charge again for up to 100%

A simpler way is just to use Battery Calibration app, it can be found on the market.
Is it a bad thing to charge the battery at 50% still?

[Q] Mango messed up my Samsung Focus Battery?

Hey, I've had my Samsung Focus since launch, the battery used to be good for a whole day and a half, and I'm sure it would have lasted at least 6-8 hours of constant use. But since I installed Mango, it only survives 3 hours or less of constant use, depending on what I'm doing. It loses about 5% every 10 minutes of doing normal tasks. And this is without 3G (WiFi only since I'm not in the US right now). With 3G the battery would die almost just as quick when it was just in standby.
Did something go wrong with my Mango installation? Because this is the kind of performance I would expect while playing a game
Dude, its not the system draining your battery. Its that you need to calibrate your battery.
Let the battery totally run out. Recharge 50%. Use until it dies again. Recharge 100%.
This may correct it.
Letting a l-ion battery run completely dead is never a good idea, and it does nothing to improve its calibration.
So what should I do? I'm honestly desperate enough to try anything now lol. Well, without necessarily spending money lol

The phone turns off automatically before the battery is completely dead, so there's no risk.

So I decided to take your advice, and it's been on 1% for like over 20 minutes with Angry Birds running, and that's with battery saver off. It just finally died. I assume the fact that it spent 20 minutes on 1% means something good? Because usually it'll spend just 2 minutes on 1% lol
It means your battery is not calibrated (phone is reporting a wrong charge)

I did this last night, it made the battery quite a bit better (maybe 50% better), but I don't think it's as good as it used to be. Should I try again?

Yes, l-ion batteries are smart. They need to be trained. If it knows it's going to get a charge the same time every day, it will adjust itself to last till then or so that's how I see it.

Wait what? That's not how they work! This is a good article on Li-ion battery.
Battery calibration is useful when your phone reports a wrong battery charge.
You are entirely wrong, RoboDad. Without a firmware update (which I hear Samsung will be offering for Mango to correctly report the battery) draining the battery is the only way to correctly have the phone report battery correctly.

Ok so I think my battery went back to being the same way again today lol, and now it's losing quite a bit of charge in standby as well

battery question

hi, is that tru, that is better to charge your device the first 3 times 12 hours? because i know that with the new batteries don´t need that like some smartphones?
and i hear that is better if i discharge totally the battery and then i charge until 100% so if that is true, that means that is not good to charge like 1 hour?
thank you.
It is actually bad for the battery (Lithium-ion or Lithium-polymer) to discharge it completely. You should always aim to grab the charger at around 20%, refill to 100%, then remove the charger.
Newer batteries don't worry so much about 'trickle charging' once the battery is full (and newer, more energy-conscious chargers may actually switch themselves off internally to prevent wastage and damage to the cell).
If you have a brand new phone, the first charge should be for 12-18 hours, preferably without use (if you can bear it). You won't see the maximum battery life from the cell until you 'cycle' (charge/discharge) it a few times, but after a week or so you should get a profound increase in battery life.
Just remember - no lower than 20%
Hope this helps!

NO! This is bullsh*t that u need to load battery 12 hrs, better take ur battery off and throw in sh*ting bowl and w8 sb to go toilet or you can urinate too and see, what happen! u can try it high voltage battery too, i hope that result is same..

for first time it is good for the battery so that it gain its max capacity..so when you get the phone first charge it to 10 hrs.and dont use at that time and also charge your battery only when it goes below 5% because every phone is having its charge and discharge life...
I usually have my charger connected to my phone, is that a bad idea then?
No special reasons to do it but if must go out suddenly and i don't have enough battery...
Yes it is....your battery ruins day by day..just charge when the battery level is below 5%'...

Thanked! My old cell phone could still power on without a battery using the charger, that's one of the functions which i miss on this smart phones.

A question about Zerolemon's Extended Battery.

Hello guys! So I just bought an extended battery from Zerolemon for my S5.
My question is, should I charge it for 12 hours before prior use like the manual stated? Or fully discharge it first before charge as some reddit folks suggested?
Thanks!
Like manual say

After first full charge, run it down to 2% like it also recommends. Help to condition battery, I do it to mine once in a while. Have this one for almost a year now and it is working quite well, can't say there has been any depreciation to run time yet.
Which app is this ??

By first full charge do you mean after charging if for 12 hours before use?

That is correct,
I may be mistaken as I don't have the little instruction sheet., but there is some additional time in hours after the phone says it has reached 100% full charge that it needs to remain connected to finish "topping" of the battery. Although I would argue that it is almost impossible, given that any algorithm the phone uses to charge one brand of lithium battery vs. another hasn't changed when the battery has been swapped out, and charging should stop once the phone see the correct internal voltage. Yet ZeroLemom recommends to leave it to charge.
The final ~10% is quite misleading as far as how long it will stay on before it finally turns off due to low voltage cut out. I had mine running for over a day and a half sometimes before it finally turns off. Very annoying that low battery message, would have liked to know a way to change the notification, or either actually entering a new mAh rating in the ROM's data so a more accurate approximation of useful charge still remaining can be properly calculated/displayed.

I see, thanks for the tip. Last question, how did you treated the battery after the first charge cycle? Did you still charged it for 12 hrs or only until the phone says it is "charged"?

I personally only left it on for about 8 hours. Typically plugging the phone in to the charger when going to sleep and disconnecting when I wake.

Hey so I got it last 2 days ago and it on its way to its first discharge now. Should I fully let the battery drain to 0% or just charge it when it hits 1%? What would you do?
It's really up to you, I would at least reach the 2%. Any further past that point may or may not matter. I've let it go before until it turns off on its own, but like I said in a previous post the low battery warnings drove me nuts.
