I've heard different things when it comes to taking care of your new battery.
When I get my new S2, should I use it right away at the 60% or so battery life and let it die, then fully charge it?
Or, should I fully charge it before using it?
Is there even a difference?
Batteries these days damage and get reduced life by holding litre levels of charge. Don't cycle the battery, keep it charged, keep it happy.

Exactly.People tend to being stuck with the old types of batteries.Complete cycling(Meaning charging up to 100% and then discharging down to 0%) was needed by nickel-cadmium batteries.Lithium ion/polymer batteries DON'T need to be treated as such.
Also,some people make the mistake to think that leaving their battery charge overnight will destroy it.Also partially wrong.Firstly,modern-day devices have smart circuits that stop supplying current when fully charged,thus preventing the damage.But the battery will get damaged when this is being done every day for a long time period,because they aren't able to discharge properly.
Finally,a full cycle is needed every once in a while for calibration,althought that "every once in a while" is more like every three or even six months.
Hope I helped!
Thanks guys. This helps.
When I charge my phone it only charges to 99%. I'll leave it in for a while, come back and it's only at 99%. Either charging in the wall, or on the computer. It used to make it to 100% then all of a sudden it just stays at 99% regardless how long it charges. So the charging light always stays on and never lets me know when it's fully charged.
Any idea why?
Thanks.
Mine does that too once in a while, randomly.
But the Sensation would do that to randomly.
Dunno why.
Battery is strange...
I get that too. But eventually it will get to 100%. There has been times where it was charged to 100% then suddenly drop to 99% even though it still plugged in.
Did you get your phone recently? I'm thinking its because the battery needs to be conditioned.
Mines always does that, as soon as I unplug it it jumps to 98%. Im hoping ARHD fixes this
I've installed Battery Widget (from Market) and it reports 100%. I plug in every night and in the morning it reads 100%.

New Amaze Android Revolution HD ROM by mike1986?
This happens with many devices. I have not seen this yet on my Amaze but I am sure at some point it will happen. Try turning the phone off and charging it to 100% then power it on also try running the battery all the way down and letting it charge to full UNINTERRUPTED over night. If those dont help you can always try another rom with better battery management or go into a t-mobile store and get a battery replacement if your battery is still under warranty. Hope this helps
HTC does this on a lot of phones. It is a safety default to keep the battery healthy and safe. I had this issue with the Evo. The only way to fully charge a battery is to have other a wall charger or a SBC kernel.
its the best sense rom known to man in my opinion.

My stock battery is 3.8v, and it only goes to 100% if I charge it in the phone. If I use my wall charger, it shows up at 99% when I put it back in my phone. I have two aftermarket batteries that show about 98% when charged from the wall. I am thinking that the phone charging circuit is set for 3.8v, and might possibly overheat the aftermarket batteries (3.7v). I saw one review that said these batteries melted the top of his SIM card. I'm not planning on trying that; I use the stock, charging every night, and swap the spares in if I run out of charge during the day.
I just remember hearing the same stories when I had my evo. You could charge for hours and unplug it and it would almost immediately drop to 99 or 98. So my previous statement may or may not help.
I charged mine over nite and woke up to it being 99%, left it for another hour or two and it hit 100%. I would say to leave it a little longer to get that last 1%.

I find that if my phone its powered off while charging, it shows 100. If powered on, it shoes 99.

this is normal for lithium ion batteries...it also depends how the manufacturer perceives the battery...some manufeacturers say that your phone is 100 percent but it might only be around 95-98...overcharging lithium ions are bad...also some manufacturers say you have 10 percent left while you might actually have 15 or maybe to percent left...this is a fail safe method to shut off the phone and keep the battery from draining completely WHICH IS REALLY REALLY BAD FOR LITHIUM IONS...OVER CHARGING THE BATTERY IS BAD TOO...perhaps htc's thresh holds are a little different and actual to the real battery life.
also not a good idea to use your phone or any lithium ion device while its charging
powering off your phone to charge it overnight is the best idea to give you lithium ion a long life but this is not practical. this is why it says 100 percent when you turn off the phone and 99 when you're phone is off....it confuses the phone: " A portable device must be turned off during charge. This allows the battery to reach the set threshold voltage unhindered, and enables terminating charge on low current. A parasitic load (which means using phone or turning screen on while its charging) confuses the charger by depressing the battery voltage and preventing the current in the saturation stage to drop low. A battery may be fully charged, but the prevailing conditions prompt a continued charge. This causes undue battery stress and compromises safety."

Any idea why the Xperia S only charges to 95% if you charge it whilst off but is happy to charge 100% when left on to charge.
It charges up to 100% then decharge down to 90% and so up again to 100% and it continues like this, to keep the battery as good as possible over a long time.

I have the same problem. I turned off the phone at 23:00, put to charge, woke up at 07:00, removed from charge and turned on, it was %95. Actually it changes, sometimes %97 sometimes %98. But if i charge it when phone is on it charges to %100 and keep it like that..
On or not the battery will be jumping from ~95% to 100% when left on charge. If you use a battery monitoring app you can see that, even whilst on and charging at 100%, the voltage changes from about 4.2 to 4.1 volts and continually up and down again. This is to increase the battery life because lithium batterys do not like to be kept at 4.2 volts for exessive periods of time.

Battery monitor clearly shows the phone charging to 95% or 100% dependent of its off or on state, there is none of this charging discharging you are on about.

When the phone is on, some battery power is used to maintain the screen backlight and the SoC. Therefore the overall battery consumption is higher, thus the system will charge the battery more, but it will actually stay at the same voltage.

The phone should charge to 100% when switched off and it clearly doesn't, you can give me all the charging mumbo jumbo you like but the handset should be at 100% when turned on but it never even achieves anything past 95%. Once the handset reaches 100% it should revert to a trickle charge not fanny about dipping 5% as is being suggested.

It works this way, whether you like it or not. If you don't, go modify it and enjoy killing your battery.

Yes, but things use to work in an optimized way, not in the way you would like to... Sony prefers to optimize the phone and the battery life than to make people happy by keeping 100% while decreasing drastically battery life...

Right I'll try one more time.
Turned off the phone charges to 95%, no higher and no lower and battery monitor widget can confirm this.
Turned on the phone charges to 100% and remains at 100% without variation until unplugged from the charger and battery monitor can confirm this.
You can see variations in both voltage and current as the charge cycle maintains either the off state 95% charge or the on state 100% charge but in either case the actual level of charge is without fluctuation.
Just picked my phone up from the changer. 99% battery.
I put the phone to charge overnight without turning it off and everyday I wake up at 100%

Not showing 100% even while left ON and charging
Tops out at 95% or 98%, but keeps varying from time to time ..... I have had the phone (XPS) for three days and not seen a 100% charge till now . Also one thing I have noticed is that the Notification light turns from Orange to Green. That's when I normally take the phone off charge.
Mine charges to 100% and stays at 100%.
mine SXS takes 20 minutes from 99 to 100%.

Which of these two ways is better?
1. Use your phone to 20%~10% of battery and charge it till fully charged.
2.Frequently use and frequently charge(charge from 60% and unplugged at about 80%, then use to 50%~60% and charge again)
Which is better for the battery's life of phones and tablets,1 or 2?
Here's how

The batteries in our phones (and most newer electronics) are Lithium-Ion (and in some newer phones Lithium-Polymer). these batteries have no 'memory'. in fact discharging them all the way is very bad for them, and can actually cause the battery to rupture if its done too extreme (you would have to short the terminals for this to happen)
The reality of this is that the less you let your battery discharge, the longer it will last. Every time you let it drain all the way (or almost all the way) you are harming it and reducing its lifetime.
The best way to take care of your phone's battery is to try to keep it between 50% and 80% full. Even keeping the battery fully charged for very long periods of time can be just as bad as discharging it fully.

The "cycles" which supposedly prolong our battery life are not true. This used to be the case, but like TopDroid said, with lithium batteries they do nothing.
Its like how on older versions of Android, task killers were useful, but newer versions don't need them and is actually bad. With batteries, the technology has progressed from that time.

I prefer 5%-15% because it gives more accurate battery stats + if you use go power master it would say "Healthy Charging"
or Method 1 as well
...
Perform shallow discharges.
Instead of discharging to 0% all the time, lithium-ion batteries do best when you discharge them for a little bit, then charge them for a little bit. The table below, from Battery University, shows that discharges to 50% are better for your battery's long-term life than, say, small discharges to 90% or large discharges to 0% (since the 50% discharges provide the best number of cycles-to-usage ratio).
Don't leave it fully charged.
Similarly, lithium-ion batteries don't need to be charged all the way to 100%. In fact, they'd prefer not to be—so the 40%-80% rule you heard is a good guideline. If you do charge it to 100%, don't leave it plugged in. This is something most of us do, but it's another thing that will degrade your battery's health.
Fully discharge it once a month.
This may seem contradictory, but hear us out. While lithium-ion batteries shouldn't be discharged regularly, most modern batteries are what's known as "smart batteries". This feature can get miscalibrated after a lot of shallow discharges. So, manufacturers recommend fully discharging your battery once a month to make sure this stays accurate.

Is this true?
you can be as neurotic as you like over this, but it really d doesn't make a lot of difference, just enjoy your phone.
Sent from an abused battery
The only big no no is to constantly discharge to below 5% and recharge . That according to the experts leads to a much shorter battery life .
Yes leaving on charge is a waste .
Wiping Battery stats does not improve battery life .
But all this is an old story posted time and again and bring nothing new .

It may be a waste but is it detrimental to the battery? I always plug my phone in when I go to bed and take it off the charger when I get up in the morning.

there is a built in feature that stops charging once battery level reaches 100%. so there will be no harm to your battery. I have doing the same since gs1
My old Nokia 3510 needed a battery replacement after 4-5 years since it only held 3 days worth of charge instead of the usual 7-8.
I constantly let it discharge from 100% (overnight charging) to empty, the replacement battery cost me 5 bucks.
My Galaxy S1's battery has, after 2 years, no observable loss in capacity with overnight charging to 100% and dropping to 10-15% over 1-2 days.
A replacement battery would cost roughly 15 bucks.
I could go on the same about my Laptop, Netbook, Tablet and other devices with rechargeable Li-Ion batteries.
The point is; don't try to forcefully extend your battery life, enjoy your phone. Most people replace the phone every 1-2 years and the batteries are designed to live that long with high usage and deep-discharging. If yours should not or you plan to keep the phone longer, a replacement battery is cheap.

All Lithium batteries have it (and need it) since there is a risk of damage, fire or even explosion when it is overcharged. That's why not the phone but the battery itself has the corresponding controller. Since the controller cannot measure the exact capacity of the battery (only an estimate), it is recomended to deep-discharge and fully charge (charge-cycle) the battery once in a while to reset the controller's counter.
Battery replacement is cheap and easy as abc. That's the benefit of having removable battery. Just enjoy your phone.
