how to take good care of you batt

http://www.batteryuniversity.com/parttwo-34.htm
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

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!

Only charges up to 95%

Hi guys,
I've noticed that if I plug my phone to the wall charger, when it reaches 95% it just stops charging. I can unplug it and plug it again, and I can reach 100% by repeating the process multiple times, but not in one sitting?
Is this normal? Does it happen to you? Does it get better?

Same here
(Using SuperAosp-ST 4.4)

i have that 2

I got to 98 once !

as far as i know, its an known bug

Its by design - charging the battery to only 95% level & then the following discharge. It elongates the battery life. It should never charge to level's exceeding the above.

It's not a bug.
Most batteries lifespan drop if being on high voltage too long (100%)
So usually manufacturers will try to let it state it is fully charged before it even reach 100% to extend the lifespan of the battery.
But if you really want to see it charged fully you can do a battery stats wipe in recovery after a ROM flash. It will be able to charge to 100% fully.
Hope that helps.

tried this methode, but no success.
i come from a X10 and SE build in a charging algorithm: battery charged fully, hold this value for one hour and let the battery fall till it reaches 90% and charge again.
do you mean such methode to extend battery life??
the phone from my boss (i9020) charges to 100%, my (i9023) only to 96%

96% is ok, as i said, being in high voltage often kills the battery. 96% keeps it's lifespan much longer.
Being said that, even extremely low voltage kills the battery too. So usually your phone will die before the battery reach 0%

Not this again
From the FAQ post, in this very forum, which should be read before posting a new thread:
Q: I unplugged my phone, and my battery dropped from 100% to 95% immediately, or it won't/takes along time to charge past 99%, what gives?
The answer leads to this informative article about what your battery gauge is telling you, and why 100% is probably not what you want ...

While I thank you for your reply and linking to that article, that is a related issue but not exactly the same. The usual behaviour is for the battery to indicate a 100% charge and then drop to a lower level, as you bolded in your post. The behaviour I'm talking about is it never going over 95%.
Not a big difference, but enough to notice the change and ask about it. Don't you think?

I myself own a GT-I9020T & have never seen the charge levels exceed beyond 95%.

You are right, your description is subtly different than the post in the FAQ. I have to admit laziness in assuming that they would be one and the same 'problem' ... apologies if they're not.

Well, you did give useful info even though you thought it was an old, tired question. I can't see a reason to give apologies there

Turn the tethering on while charging; it'll charge the battery up to 100%

I think my Vibrant had the same issue / feature. It's probably a Samsung feature and not a bug.
Sent from my Nexus S using XDA Premium App

Mine hits 100pct sometimes but will always stop charging until it drops below 90. A good feature to save the battery. Makes 0 sense for it to be charging every time it drops 1pct for hours at night while on the charger.
I'm wondering if people seeing a difference in the overall charge cap is a matter of rom? I've been using cm for practically ever but I know some people are on stock. I'm sure it's possible something is modded in there to make sure it hits 100 before it stops.
Just a thought.

On nexus s with stock rom I was able to charge to 100%

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!

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%'...
Xperian8~ click thanks if it helps...

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.

Battery cycles and fast charging

I have gone through about 3 cycles if battery, with fast charging turned on. Battery life has not been good, especially with screen off drain. Getting about 3hrs SOT while I've heard people say theu get around 6.
So my question is how many cycles should I go through before I judge battery? And should I disable fast charging? Does fast charging damage the battery?
I have the verizon US variant, so there isn't much I can do to improve battery life without root...
Thanks

Turn fast charge off. Turn off AOD. I have an AT&T model. Helped my battery immensely....

I can go the entire day, 6am to 11pm, with average usage and have about 40% battery left. VR drains my battery like butter on a stove.

I'm also on VZW and I've had my S7 for a week. After about 3 days of poor battery life (~2hrs SOT), I turned AOD, location, BT, and NFC off, and disabled a bunch of bloatware (I posted what I did in the battery thread). That improved my SOT to over 4 hours +more standby time. I've since re-enabled BT and location and haven't noticed a difference. I left fast charge on but I use a slow charger at night, just because that's what's plugged up behind my bed.
Sorry, I don't have a source but I'm pretty sure I read something credible that said fast charging doesn't affect battery life/quality. I know that's pretty flaky, so take if with a grain of salt because plenty of other people are saying it helps.

I too have some similar questions just like @gleggie has posted
"how many cycles should I go through before I judge battery? And should I disable fast charging? Does fast charging damage the battery?"
Also how to measure battery cycles? Any credible app for the same?

Fast charge doesn't affect battery life immediately, charging your phone faster causes heating and overworking of battery, so slowly, average battery life decreases.
Slow charge when possible! (Wireless charge generally heats more than wall charge!)
... My 2 cents

My phone on fast charging, even wireless doesn't get any hotter than previous phones. My other half has a HTC One M8 for two years and still gets 5-6 hours SOT and has fast charged since day one.
I use fast wireless charging and get 6 hours SOT.
All I turned off is NFC, and my signal is usually full.

So, to slow charge a S7, do we have to turn off fast charging from the settings and then charge via the charger that came with the phone(the so called fast charger) or should we use a charger from an old phone say SIII etc.?
Does this hold true for Motorola's phone also which have turbo charging option?
Also how to measure battery cycles? Any credible app for the same?

Just turning off fast charge you do a lot good for your mobile..
One thing you can do is check battery temperature as you change charger or method. I don't know about Motorola, but maybe its battery is user replaceable... I personally don't know any app that keeps track of battery temperature

Thanks for replying. I wasn't able to find any battery cycle file/log in that location, quite strange. And yes I have the Exynos version. I will test your app and will get back to you.
Of the little what I have understood from various threads here is to charge the battery when it is between 20-40% to 80-90% if you want to have a good battery life. I used to do the complete opposite charge, when the battery is at say 6-7% and charge it till it is maxed. I used to do the same for my laptop, any other tip for the battery?

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.

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.

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.
