I use the tablet a few hours a day (say, 6 hours) and among those most of the time (say 4 hours) it is on my desk so I can plugin the charger if I want.
My question is in this case what's the recommended behavior, for the purpose of saving battery cycles (I mean, say, after a year, the battery life per charge is reduced less compared with when it was new)? Would it be better to use the whole day without charging it, and charge at night? Or Charge it whenever I can?
Thanks for your advice!
Keep it plugged in. The battery will not overcharge and it wont effect the battert cycles as much as draining it and then charging it. Its better to do shallow charges (above 50%) than deep charges.

I am using p500 from one and half years and i use it heavily so i have to charge it every day. Now i feel that the battery has done his job
And now i am getting a poor battery life

> how poor is it? about how many hours on normal usage? I use mine heavily on one day and it last 8-9hrs
I'm using my phone since 19 months and battery is fine heavy usage gets me 8-10 hrs battery while moderate gets about 24Hr and simple usage(just for call and msg) gets me more than 50hrs..
A Lithium-ion battery has normally 400-1200 charging cycles (Ref. Wiki).
Couple of things that shorten life span of a battery:
1) Complete discharging, it is recommended not to go below 20%
2) High temperature which implies that if you OC too much your device will heat up and battery life shortened
3) If you consume 50% of your device battery on day 1, recharge to 100% at night, and do the same thing on day 2, then you would have just finished up one charge cycle of its battery life. Constantly recharging a lithium ion battery does not shorten the battery life more than normal usage would. Hence constantly recharging a lithium ion battery does not shorten the battery life more than normal usage would. Avoid letting it sit on empty for too long; instead, keep it charged-up if you can. (REF.)
My battery behaves in a funny way. With moderate use it dissipates very fast. and then if I keep screen off for more than 10 mins then my battery starts regenerating automatically(5-7%)
I noticed a few times, with some of the phones or devices I used to own, that if you, for example, after charging the phone, let's say play a graphics intensive 3D game for 15 minutes, the battery meter will drop quite a lot(e.g. 15%). But if you leave it on stand-by immediately, you will notice that after some time, the battery meter will indicate with 3-5-7% more than before.
My battery life is under 2 hours in 3g continues downloading!

I think it's "normal" to charge it every day!! if you use it!! i charge it at least one time a day..
Lithium battery's do last a long time but they do loose there charge and become weak. After a year and a half I would defiantly consider buying a new battery. I wouldn't recommend the cheap $3.00 battery's but I would look on eBay or amazon and find a stock o.e.m battery. Brand battery's are more expensive but last probably 3-5 times longer then cheap battery's. I've read and heard that lithium battery's are not suppose to get hot but they can get warm, if the battery gets hot then it can destroy the battery and won't hold a charge as long as it should.
It also depends on what ROM you are running and what applications you are running, all that can add up and drain your battery fast. I would change a battery on a phone about 5-7 months or maybe even up to a year. Depends on your budget and what you can afford. hope this helps

So I'm starting to remember how weird the charging of Note 10.1 is. I left it chargong for a couple hours and it barely charged, course it was on.
Do people "Power off" there notes before they charge it, or just plug it in and walk away?
Is there an app or some setting to auto "hibernate" or even shut off when it gets plugged in and not used? Just seems like an annoying habit to have to power it off regularly.
Note take a long long time to charge 5 - 7 hours for a full charge.
I always care mine while on, usually wifi and it charges from 20% to full in about 5 hours using AC. If you're charging via USB and it's powered on it will barely charge (its charging at 1/4 the current).
If you're using AC and it's still taking that long, you must have a battery hungry app running, try killing a) apps before you charge.

mine usually takes 5-6 hours to get fully recharged from 15-20%
I usually just leave on in the night. Wake up and it's fully charged.

any "speed charger" option? 6hr sounds ridiculous, particular if it's used heavily on the go ...
You're talking about 7000mah of raw power. So this takes some time to charge...this is just plain physics

You may be able to charge faster, I know there's a fix for the SGS3 but faster charging causes more heat which will kill your battery VERY quickly...
Unlike the SGS3 you can't just get a replacement battery and swap out easily... Slower charging will maximise your batteries life....
Yep, forget about charging quickly. The battery is high capacity so it should take maximum 5 hours. It may charge faster with a different adapter but that will shorten your battery life in the long run. If you want, you can buy a battery pack type portable charger I guess...

As everyone else has mentioned. Charge it at night.
Is it safe to charge the battery overnight?
I mean, charging more than 100%, charging over the 3-4 hours needed, charging for 7-8 hours..
I think it won't effect it cuz i charge my phone from overnight too.nothing happens.
when battery gets full it stops charging after that
Of course
I've been doing that for a year.
Usually my battery reaches 10% at the end of the day, then I just leave it charging over night.
Thanks, i've been doing it since I bought the phone but I've never really cared until now..
Do you guys turn off the phone before charging overnight?
No. I don't know how does it affect the quality/capacity of battery though!
I remember as a kid I had those RC-cars and there were always warnings about how it will 'destroy' the battery if it is charged for too long. lol.
I don't have any battery problems.
Just make sure your LED isn't turned on!
I once forgot it on overnight...
It's a little dimmer now. :c
They said once it reachs 100% to stop charging. It can have an negative impact on your battery. Lithium technology or not. But I do it too. I think it just shorten the life span on a slow scale.

Here is the thing...
Yes the phone has a voltage shut off when it reached 100%.
However, it will start to drain battery immediately once it cuts off charging. Even when idle with teh screen off it uses some power. And once it drops to 99% it will start charging again until it reached 100%.
Depending on your set up and how much the phone runs when idle it would keep 'topping off' the battery several times overnight. This is harsh on the battery.
So it's not like once it cuts off charging it stays off until it's unplugged and replugged in. It'll keep charging everytime it drops to 99%

Hello. My Moto G since I bought it has some major battery issues. It charges very slowly on the USB charger and a range of wall chargers. One night the phone turned itself off within 10 minutes of me putting it down from 35% battery to 0%. Then last night I was charging it and saw it go from 65% to fully charged in a split second. From the moment I unplug it after full charge, it will last 7 hours with moderate use. Mainly msging on whatsapp andbrowsing in chrome. So I do use it a lot in those hours whilst I'm out etc but it seems to drain whilst it's in my pocket with the screen off. The screen on time has never passed 3.5 hours with brightness on lowest.
I don't find that too bad but the random flash drainage and charging of the battery I have experienced is concerning. I mainly have 3G/H+ on and very few apps other than whatsapp and instagram plus chrome. I have tried a factory reset too. The battery usage stats is just my screen And the usual stuff.
I really think you should considering buying a new charger.

It seems pretty common this battery issues with Moto G, i was considering buying one but now i'm not so sure..
Hmm, today I carged with iPad charger (2A) and after unplug, half hour later (autosync is disabled, no games, no music, no chat etc, all possible apps disabled, not rooted) checking once email the battery level was 87%.
Strange.
I read somewhere that charging at 2A well degrade the battery with the benefit of charging it faster. Is this true?

There is current limiting built-in, with Li-ion so you won't damage or over-charge.
However, heat generated by long-term charging can degrade the battery....
See this:
Battery Charge Levels
Quite simply, it is not possible to overcharge a cell phone battery. However, leaving it plugged in for more that 24 hours can cause it to overheat, thereby shortening its overall lifespan. Most Li-ion batteries and chargers contain internal circuitry that stops the charging when it hits 100 percent, but always unplug it after long charging intervals, just to be safe.

Hi,
The battery in my moto g, the system oper. android drain a lot of % usage, 34% more than display in 6h usage.
In most cases this drain over 5 or 10% battery. What can be responsable for this consumption ?
my battery status:
5h usage - 32% screen (1h) sist oper.(35%) 4h
regards
Here is the full question: Does modern smartphones protect the battery making energy bypass baterry when it is full charged? (like most laptops do)
This is related to: is it bad to keep my phone plugged to the wall charged for 15 hours? is it true that doing this makes the baterry go 100%-99%-100% and it "drains" battery's life taking cycles?
Is this the same for all devices? I have a Samsung Galaxy S Advance (i9070)
Thanks!
EDIT: MODS, feel free to delete, i couldn't because there is not such option! I posted this in the wrong sections.
thanks.
The charging circuit lowers the charge to a trickle, to keep battery charged.
I find I can get an hour or two more phone time if I keep charging after it says 100%.
If every thing is working right you shouldn't damage the phone or battery.

Subscribed to this thread as I am very interested in the answer myself.
It is float charging at that point. Battery levels are determined by the battery's voltage. A fully charged lithium ion battery sits at about 4.2 volts while a nearly drained one would sit at about 3.3 volts. This is how your phone knows when to stop charging the battery. So when it gets to the highest point, it stops and lets it trickle out a bit. Then when a little bit of energy has bled off, the charging circuitry kicks back on until it reaches the threshold again. Then the process repeats. It does this to maintain a healthy battery level without overcharging. Hope this helped

Thanks for the information. Its very informative. :good:
Will constantly charging a phone result in reduced battery life?
Constantly charging a phone will not affect battery life because it's just float charging. Float charging keeps batteries charged but not too charged, drained but not too drained. Of course lithium ion batteries will just eventually wear out because they're good for about 300-400 full charge and discharge cycles. But that's FULL charging and discharging. If it's float charging, the battery will stay good for years.
