[Q] Draining battery on first use?

Hi guys
I should be picking up my SGS2 today and I was just wondering what exactly I should be doing with the battery? I've read in a bunch of places that draining the battery fully and then recharging it fully gives better battery life, but I've also read this:
Lithium ion batteries do not respond well to full discharge, you will see reduced capacity and early failure if it happens too often. In any case it is not possible to overcharge the battery on a BlackBerry because the battery and phone have enough intelligence to control the charge (unless the battery is already defective).

(this is from crackberry.com but you get the idea)
What's the best thing to do?
And on Android phones, when the battery indicator shows 20% or something, is that when the phone is going to die? Or will it die at 0%? Obviously at 20% it would be to protect the battery but maybe Android has been programmed to show 0% when the battery is actually at 20%.
Thanks,
Elliott

read manuals !!!!!! You can see this

Did not receive an owners manual with my phone. Anyway...phone is charging now so too late I guess...

The manual is probably stored on the phone, at least my new Ascend II came with its stored on the phone, you have to goto the big menu (forgive me for not knowing the technical term for it) to find it however

i got my battery fully charged...then in the first day i discharged it till 10% at least that's what my phone was saying
i read too that the new li-ion batteryes do not need to be "formated" (fully discharged till the phone dies and then fully charged with the phone turned off) in android case i think that thing is not posible coz it needs at least 5% to pass the bootloader and then begin to charge
anyway in my manual it says that the battery will begin the normal state after 8 days of use, until then it may disschage quick
i have a motorola defy

Calibrate the battery. Charge the phone while its switched off for about 6 hours, and then use the phone untill the entire battery runs out and it switches off on its own. After this, the phone should be able to use the battery properly.

i just used my galaxy and made it empty, then charged it full.
nowadays i have runtimes from 3days (72 hours) and then its @ about 5%

there seems to be a lot of back-and-forth regarding whether or not draining a battery is healthy; i drain my iphone battery down to zero about once a month and the battery has been doing fine for two years . . . whether it would be doing just as well without the draining time is anyone's guess.

I have always been under the impression that lit-ion batteries do not need any kind of special care or break in. But since our phones estimate the charge, we should occasionally let the battery run out to reset the calibration in case it gets screwed up.

I don't think you need to worry about draining the battery till it's dead. My phone dies often and the battery is still kickin It's my understanding, that the purpose of draining the phone before you charge it is to calibrate what the OS says for charge remaining to the battery's actual charge.
Or something like that...

Hi all,
I have my sgs 2 since June and it's working pretty well apart from the battery drain which is very harmful in my daily life
I've recently flashed the Cognition 1.30 (last friday). Before that, my sgs was able to last the entire day before discharging with a moderate use (10-20 mn on games, few sms, 15 mn consulting mails, 1 hr on internet). Since i've flashed with the cognition Rom, the battery drain is really awesome!!!!!!
I fully charge the phone (switched off) then when i switch it on and the phone stays idle, after 1 hr or so, i've already lost almost 20%. When i'm on internet or playing games, the battery loss is approximatively of 1% per min.
I've made a full wipe and recalibrated my battery so normally it should at least last a day and thats not the case.
Could somebody help me or should i buy a new battery and test it ?
Because i relly like this rom and from others users, it has a good feedback concerning the battery use

[Q] battery takes 2X time to charge after flashing the ROOM??

Hello everybody,
to begin with i must say that my phone's battery used to take 2 to 3 hours max to charge from wall charger but now since i flashed the ROM and it has been acting so weird when charging. I have monitored the charging time and found that
after 1hr the battery goes to 50 %
after 3 hrs its up to 70%
after 5 hrs its up to 89%
then after being on charge for 6 hrs its fully charged !!!
p.s the battery lasts the normal time it used to.
so what's going wrong here?
your help is much appreciated!

You're using the same charger right? I believe aftermarket chargers are slower and suck!

Yes its the same original charger!!

The only suggestion I have now is to double check if it's really because of the rom?
Try using another rom for a day or so and see if it also takes you that long to recharge. Don't restore apps or anything yet either! (could be an app causing it, however that's unlikely) Mine only takes long to charge if I'm using too much stuff while charging it.

It is normal. Charge voltage is lowered when reaching 70% (or 80%, you can check it at battery stats) and then even lower when almost full until it is really 100%, not to harm the battery pack. Your previous cycles only semmed faster, the more you use your phone the better your battery stats will be.
If you wiped battery stats before, it could be another reason for strange figures.
Most importantly, if you want to have a good battery life on the long run, dont fully discharge/charge it.

Battery trick

Ok guys often we unplug charger when fone says 100% but i found a simple trick. I installed battery saver app
https://play.google.com/store/apps/details?id=com.ijinshan.kbatterydoctor_en
Even after 100% the charging system enters trickle charging system which takes 10 mins even after 100%. Point to note is when the status is at 3 the fone reports the batt is 100% but that is the time trickle charging kicks in..and doing this my battery did showed little more improvement
Please note : I did not use any batt saving options via app i just used it for monitoring the trickle charge...​

Really puzzles me why such a basic app would need to many permissions. Better apps on the store that requires much less permissions to run.

No idea bt it did help...thats all

No need for any app to do this, I always let my devices to charge at least 10 mins more after reaching 100%.

No need for this application as phone does not give message of fully charged even after reaching 100% and status will be " (100% charging). Once the trickle charging is complete you will get message on lock screen" Fully charged".

80%
There is an option on my Samsung laptop to only charge to 80% to prolong battery lifespan. My Note 3's battery is so good, I would rather see such an app that would stop charging at 80% or 90%.
I usually have 50-60% battery left by the end of a long day. And that's with quite heavy work. I stopped plugging in the charger in the car for my commute, there is no need!

Wow! I agree that the note 3 battery life is the best I've experienced so far but mine is not as good as yours. Will have to try your method of charging to 80%.

When i forget my phone in the charger all night, i get like 20% more battery life out of it!

Just charge it overnight.

On the big screen U do not do anything ... For normal use the battery life is max 2 days. With gaming max 1 day maybe less...

Charge every night?

Coming from a Nexus 4 I have got used to charging my phone every night. The battery on the z3 is a lot better, it comes off the charge at 5am and as I type it is 10pm and the battery is still on 66%.
Would I be doing the battery any harm by putting it on the charge every night? I know it can last me through work tomorrow but I like the have it fully charged for peace of mind.

Lithium Ion batteries last a number of charges, slowly losing the capacity to hold charge as the number of charges increases. Why don't you charge the phone when it needs charging? You can always use stamina mode to keep it going until you get to a charger if you need it to last a few more hours.

I believe its about 350-500 cycles to 80% capacity. Also when your phone says 0% Battery its more like 60% (Don't quote me on that) capacity to prolong battery life.
You should be fine for the life of the device.

TL-DR - charge every night, don't worry about the rest.

you should not be worry about battery problem in xperia because there 2 power saving option normal stamina and ultra stamina so you can take your phone for whole day usage even on ~60% of battery
:good:

so is it ? or is it not bad to charge it every night? even if the battery isn't low

Standby is really good. If you go to sleep at 66%, it will likely be at 66 or 65% when you wake up. You might not need to charge till tomorrow night.

You don't complete a discharge cycle, when you charge with some charge % left so its good to charge it, you are fine.

I charge it every night. It is between 40-60% full when i connect it. If there are some 350-500 charge cycles untill capacity drops to 80% then it is time to upgrade anyway so...

for lithium ion batteries in mobile phones just recharge as it suits your day. Yes, you might be able to preserve some single digit percent over the long run but there won't be any dramatic losses if you don't take special care

will using the 6x while charging does any harm ??

can using the phone while charging can harm charging port or battery ? im asking this because i was using some days ago my galaxy note 3 like this one day and it stopped charging and was dead..

I don't know about harming the port but, it will definitely hurt the battery, So I don't recommend doing this except when it is an emergency

Note 3 was launched 4 years ago. Battery would have gone bad, you would have noticed the degradation.
In some phones, especially those which charge very fast, the temperature can rise to a high level which reduces the life of the battery, but should not impact much if you are using a phone for 1-3 years. Though one needs to stop charging / using the phone if the temperature reaches very high (say above 60 degree Celsius).
Honor 6X charges very slowly while using and the temperature doesn't rise as much (as compared to other phones), hence that impact is likely going to be lower.

Generally it's not a good idea to use whil charging all the time.

I strongly suggest you to use the phone while is under charge the less that you can, especially being careful about using it in combination with mobile data/GPS services/internet browsing and apps that requires particularly usage of RAM. This because the li-polymer battery plugged on charge with the original charger of 6X, that supports fast charge and so will "push" inside it a stronger power than a normal charger, will almost immediately reach a voltage of 4.1-4.2V to ensure the fast charge service and this is the limit that you want to maintain for being sure that the battery will last the longest time. Using it under charge with mobile data or others mentioned above, will easily overcome the 4.2V limit to 4.3V or even more, depending on what you'll be using, and so the ions capacity will be reduced faster, letting them contain less energy than the original capacity while time passes by.

It definitely does hurt the battery.
I try to never use it, except when in emergency

It doesn't but thats not a good practice in general. With continuous usage, it may get more heated that is not good for battery, phone and eventually you.
Because charging itself will hear up the phone and using it may increase further so avoid it buddy.

Agreed. Charging phone for long time may impact the battery health in long run

I always charge my phone overnight for these years and nothing happens... maybe I switch phones too fast to notice battery issue... :silly:

Hehe may be. I will take time to charge in morning or in night during dinner for 20-40% and then in morning for another 40-50% or if wake up early then may be i charge full 100%. Anything above 80 ia good for entire if couldn't charge full still have 20-30% left when reach home in night.

Almost the same here; i limit the charge to 80% with Battery Charge Limit, i wake up at morning with 79-78%, i go at work and when i come back at evening usually i have around 55-60% left due various jumps here on XDA, internet browsing, some calls and a few messages. When i go to bed i plug in the phone just for a mid-hour so it can reach 80% again, then i remove it from charge and so on.
