[Q]Charging the brand new Incredible S

Hi
I have a question about charging the phone when I first get it. I wanna maximise the battery life. But usally when I first get the phone, the battery has a bit of charge. I've been told to charge 8hours.
So do i drain the remaining battery and charge 8hours with the power on
or
Do I charge it straight away even though its not low battery for 8hours
Or do I just charge it till the battery is full?
Thanks

drain it completely, than put it on the charger for like 8-12 hours
drain max again
charge it long time again
drain max again
charge it and your done
this will give u the max result of your battery

Thank you very much. I shall try that, Should I Leave it on while charging?
Is it okay to play around with the phone while it is charging?

1; There is no need to do that with current technology batteries.
2; Once the battery reaches 100% it doesnt charge or do anything else.. so useless to leave it in for 8-12 hours.

I second TimMun.
The process of charging the battery for 8 hours is for old batteries...
and i believe even that was a myth.. apparently the concept was that the acid in the battery needs to be charged for a LONG time for maximum efficiency.
I think you are good to go once the new battery shows full charge..

Hmm wonder what was in my study about batterys, well do w/e u like, i know a bettery has a memory which only can be reset by a deadly shock which can be fatal

[Q] Any disadvantages of frequent charging?

Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?

Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..

True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.

Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.

As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.

Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.

frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....

FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

Battery % drop

Recently I have been taken tablet of charge at full 100%, yet it drops to 99% immediately and then down to 98% after about 4 mins.
Anyone got any suggestions to keep battery holding 100% longer?
Ta.

never better than ipad. battery charge daily.

will the battery be ruined if phone is constantly plugged in?

i'm currently using my note 1 as a secondary monitor and it is plugged into the standard charger while doing so. Will the battery be constantly 'zapped' as I use it? or the battery can remain 'like new' if it's always plugged into AC?
Thanks!

Might be,might be not. I did that sometime, even on my laptops without any problems. But the recommended is unplug when it full charged and charg when its 1-10%. I use battery doctor app for trickle charge for long live battery. And btw the OEM stock bettery is cheap anyway. From now till ur battery is getting drain like hell its would be take like 6month to a year.
Just saying ...

It's better to discharge it completely, then recharge it completely from time to time.

Full cycles of charging and discharging keeps the battery healthy for a considerable time.

Also, keeping the phone on charging even after it hits 100% causes the battery to swell. You will not see the effects immediately, but after 4 months, the battery will be swollen on one side. And swollen batteries like to self destruct.

Every battery can be recharged several times[for exm: 500] If you charge it 5 times per day = 100 days battery life. So i think its better to dont remove adapter when battery hit 100%. The new cell phones and laptops got protection and they dont charge the battery when its fully recharged.
This is just my opinion.

Some time ago I did a little research, because I was using my phone as a wi-fi modem for my laptop. Most opinions said, that constant plugging may affect your battery life and best is not to keep it plugged when fully charge too often and for too long.

no it actually does not cause this... the batteries and phones have smart circuitry which prevents battery overcharging.
now fully cycling a battery 1-2 times a week will extend the life of the battery..

As far as I remember from the tech-news, newest energy cells (li-ion and li-poli) shouldn't be charged like the old ones - I mean charge 12h, then empty it completely and repeate the whole process 3 times. I read it on polish site some time ago and they we're also saying, that keeping phone under chargerer can harm battery or even mainboard.
But as we can all see, there are many different opinions about that

My old note battery swelled and it was because i put it on plug before sleeping to get 100% in the nornibg my battery swelled within months and i had to change it....
I have experienced the battery awelling.

hmm, that's what i do every night (for sleep tracking), but my battery didn't swell (both OEM and original).

Mine did. Swelled a bit on the side, cover used to creak whenever I pressed on the other side

All (reputed) devices that use Li-Ion batteries use controllers that will automatically cutoff charging once the voltage reaches 4.200V/cell.
So you cannot over charge a battery by leaving it on for long duration.
Unlike the older Ni-Cad batteries, there is no memory effect. so there is no need to fully discharge it periodically
In fact, deep discharge of Li-Ion battery will irreversibly reduce battery capacity (Wikipedia -> Li-Ion battery -> Battery life )

[Q] Charging questions and asking for tips

Just an inquiry. I just got my sony xperia z1 last week and may I ask if its okay to charge it even if it's still 30% . And if it is okay to remove it from being charged when it is not yet 100% charged.
i read on some articles that the battery of my xperia should not be 100% charged because it can hasten the aging process of my bat.
any suggestions ? thanks! I just love Xperia so much. It's so awesome! :good:

No that was a very old technique, not applicable anymore

yes. charge it to full, plug it in whenever you want, etc.

how long should it take to fully charge the phone ftom let's say 20 to 100%?
I have the impression it is taking too long for me as it went from 20 to 50% in 3 hours
Is there an app I can use to check?

That is so long. Are you using the charger that comes with it or an old charger?
mine takes ~2.5 hours to fully charge from 15%. But when I use my old X10 charger, it takes twice the time.

in case youre not using the phone during the charge:
(this calculation will not be perfect but good enought)
20% left means, that 2400mah of your 3000 are used.
your default sony charger has an max. output of 1,5A.
that means you can charge 1500 mah /hour
that means you need 8/6 hours to charge from 20% to 100%

wot?
the phone is supposed to fully charge in 3 hours...

I guess my estimates would be like 2hours tops to get me full charged. From 4%

Just charge it when you go to bed if less than 30% if more than that, Charge it it morning If above 50% should last a working day on stamina mode then charge it fully when you get in, I get about a day and a half which sometimes makes it awkward, unless you can charge it at work?:fingers-crossed:

I really don't understand this z1.mine took 6hours to charge today turned off at 1%.first time charge took more than 3hours.and once it took 3hours to charge 40 then another 2hours or so.but I searched the Web and people have said 3hrs to 4hrs max.and under 3hrs if phone turned off. Is there something wrong with tye Xperia z1?
