As far as I can recall, that is even better than charging it to 100% all the time.
You can charge it as much as you want before going out
Its important to cycle your battery properly when new, (i.e. charge to 100% and the near enough get it to 0% before recharging to 100% at least 2 - 3 times), but once cycled, you can charge it as much as you want but try to keep it above 12 - 15% mark, (once cycled).
Most phones use Li-Ion batteries, these can be topped up repeatedly without ill effects
Guys I am wandering, can you harm you're phone if it's left on charge overnight on the quick charger? I put mine on to charge right before I go to sleep, then I take it of if I wake up during the night, or first thing on the morning. Is this dangerous for either the phone or the charger??

Nope. Android will charge to 100%, then let it drop to 90%, then recharge to 100. It wont cause damage/fire etc.
Thanks so much for clearing that up for me

I have always charged my phones overnight and it has never done any harm. Looking on the battery monitor widget the Xperia S charges just like everyone other Android phone i have owned, up to 100% full then just remains on a trickle charge.
Be carefull. It will blow up..

As the title days. I bought the spare battery and wall charger from sprint for $41 and after 2 min after I turned on the battery I decided to check what mv it was at. Was at 4255mv. I bought it cause I usr phone constant especially on my bike rides and coming from the Evo I know now that batteries Def have so many charges till battery performance goes down.this way I van go from 100รท till phone dies swap out and out fresh one in. Every time you hook up the charger even for a sec its a battery charge cycle.

Have always wondered this about smart phones and batteries. If I buy a spare battery and charge it fully then take it out of the phone. Does it dissipate at all? And if so at what sort of rate? Cheers
Eventually.

Li-ion batteries will hold a charge for quite some time. I have 2 spares for my fone and I use a dock to charge them.. generally only use 2 a day but sometimes the 3 on a busy day and always got 100% showing when I change the battery out.. you can Google the battery university there is a link on here but I can't remember where it is. That explains a lot of stuff .. hope this helps

I use two battery's and never have problem with it losing charge sometimes I don't use the spare battery for 3-4 days and still get 100% battery when I swap them over.
Hope that helps.
Pretty much will start to loose change the moment you take them out of the charger but still still have a lot of juice in them weeks later. Normally when you buy a battery it has about 50 or 60% charge already and think about how long that has been away from a charger ... shipping time, time in a warehouse, then in the shop etc.
No worth worrying about unless you aren't going too charge them for 6+ months. In fact I had a spare for my sensation which sat in a drawer for 3 months and it still had over 90% charge from full.
Then again I got a cheap tablet which the store owner said had been in the shop for a year and that battery was almost flat, like 3%.
It would have left the factory some time before that with around 60% charge so it will have taken far more than a year, maybe as much as 18 months, to go completely flat. Also remember it would have been a new battery which hasn't been thru a few charge cycle to reach maximum efficiency.

Thanks for everybody's input. I think I've got our down now Lol. But I'd like to keep the discussion open for anyone that would like to be better informed.
New topic: Tips & Tricks for getting the most out of your battery.
Thanks guys!
Don't run it dead regularly (that was for ni batteries), don't charge it all the time (ie topping off everytime you're near a charger). If going to store powered down for long periods do so at like %60 capacity.

Just to clarify, you saying to not charge when battery it has more than 60% charge remaining? If yes. Then how low do you recommend as to minimum charge left on battery when you plug it in?

It's been a while since I have actually cared about a phone enough to really want to take care of every part of it, including the battery, and I was wondering what the best way to keep it fresh is?
Use until it dies and fully charge every time.
Use until low power warning and recharge.
idk what other methods there are....
Anyway, appreciate any and all tips guys:good:

Best way is to not worry about it. Only thing you want to avoid is letting it die in standby over and over.

Sorry I was so brief was at work on lunch.
In the ideal world you'd probably charge around %20-%30. Lithium batteries do not like being over drained or overcharged. Overcharging isn't really an issue since our phone handles charging. Over draining repeatedly will drain max capacity, same with overcharging. The %60 i refer to is a rough number if you were going to be storing the phone powered off for weeks or months, lithium batteries should not be stored at max voltage or drained.
You don't want to be constantly "topping" your battery off either. The life of a lithium battery is generally going to be measured in charge cycles. So charging it every time you're sitting at a charger will really just wear it out faster.
I generally just charge my phone every night when i go to bed. With as long as these phones last on a charge; I've yet to burn through my entire battery in less than a day more than a time or two. Don't put too much thought into it or worry too terribly much. Running it down once or twice isn't going to do much that you'd immediately notice, but doing it every time is certainly not a good idea!

Okay. Thanks for all the info. It really helps to know that stuff. I'm not to worried about burning through charge cycles. I'm getting 2-3 days of a charge. 4 if I drain it. Battery on this is the best I have even seen. Truly incredible. I don't know how they managed it. But I am absolutely loving it.

The only thing you need to worry about is not letting your battery reach below 14%. Unless your out or not near a charger it's understandable.
Charge your phone once it hits 14%. Let it fully charge don't interrupt it (unless you have too)
Sometimes don't charge your device to 100% I sometimes charge mines to 90%.
Let the battery die once or twice a month.
Just don't worry about the battery. By time you hit anywhere near 500 charge cycles you'll be on the m9 or a new device.

Why would you only charge to %90? And why would you let it die once a month?

Because you wanna train your battery and get the most out of it. A lot of people say those are old rules because these batteries don't have memory cells. But you'll find yourself not needing to replace the battery as fast as you would by just letting it die all the time
I have replaced a cell phone battery yet and I've been using that method since flip phones days

Hhrrmmm. i think you're thinking of nickel based batteries (nicd, nimh, etc). Generally lithium cells really dont like low voltages or have memory.

I think he's correct on the letting it die once every month or so. I did a lot of research on this a while back and ideally you don't let your phone drop below 50% regularly and don't let it sit on the charger all night since its going to be at 100% for many hours before you wake up a li ion batteries prefer to not be at 100%. The discharging it fully will calibrate it and make sure all the cells are being used since if certain cells don't get discharged every so often they start to lose ability to hold a charge. Keep in mind I looked all this up 2 years ago and most of the issues only affect people who keep phones for 2+ years unless the do 100%-0% every day then their battery won't last long.

These phones all have battery protection circuitry built into them.
As the battery approaches 100% charge the charge current reduces to almost nothing to prevent overcharging.
Having said this I would not leave the phone on charge for weeks on end but there is really no reason to worry about taking it off charge the moment it shows 100%.
Likewise for discharge. When the phone indicates that the battery is getting flat it will make sure that even if you run the phone till it dies, the battery will not have been allowed to overdischarge. When your phone switches off software is telling the phone to power down to protect the battery.
Also, to touch upon Lithium battery charge cycles, one charge cycle is the 100% charging of the battery, now keep in mind this can be from 0-100% OR it can also be the sum of multiple chargings up to 100% capacity of the battery
I.e.- charging from 75% to 100% once is not considered a charge cycle to the battery, but do it three more times from 75% (25%x4=100%"rated" capacity) and it considers THAT one charge cycle. So if you charge from 50% regularly, two times charging from 50 to 100% is ONE charging cycle.

Few months back I was speaking with HTC support, the rep said don't put your phone on charge for more then 1 hour with any lithium batteries.

As usual, speaking with reps can be cause for alarm. In this case, it's obvious he/she was blowing smoke. Read the links posted in the thread.
Updated OP. This is now more of a help thread for those who need it. Thanks for all the info and tips.
Let's keep it going guys!
