Battery Life Question
I heard someone said that they waited til they're EnV Touch phone die, then fully charged and overtime repeated it gave him more battery life. Is this true with alot of phones?

Basically, your standard lithium ion battery has some interesting charging properties. The battery is designed to be charged within a certain power range and within a certain amount of time. For instance, if I were to make a charger with higher voltage than a standard charger, the time difference would be nominal at best. There's a lot of technical stuff in there.
As part of the design, a lithium ion (or polymer lithium ion) battery has no memory effect, but does lose it's internal stability over time with subsequent charges.
What I've found over the years (and others have seen it too), is that the longer you can go on one charge, the longer your battery will remain stable internally. In some cases, I've seen people charge once a d...

Also, something else I've seen over time - if I happen to have a partial charge (going against my own habits), I usually find my battery life is diminished for about two to five days. Meaning, my battery dies sooner at the end of the day until I've had a few normal charge cycles. This might have something to do with the built-in charging protection on most LiOn batteries, because your charger has to do a final stage charge after about 70-75% charge. If that final stage doesn't happen, your battery is only partially charged AND still needs to complete that final stage charge to be "full."
I've also seen it before with car chargers, but I think that's because people rarely fully charge their phone with a car charger.

Without diving into the chemistry, the best advice I could give is to charge as infrequently as possible.
A failing lithium ion battery isn't like the old school battery failures. Old school rechargeables with "memory" effects charge up to 99% or so of their most recent full charge each time they're fueled up, so they die gradually over long periods of time. Lithium batteries typically work great for a really, really long time, then drop down to almost worthless in a period of weeks (or less).
A lithium ion battery is basically good for a fixed number of charging cycles after it leaves the factory. The average is between 300 and 500 charging cycles, then your battery will start to fail.
Here's the kicker: It doesn't matter if y...

About a year and a half ago, RIM released a software upgrade for my BB Storm 9530. Prior to the update, I was getting 2 - 4 days out of my battery. Immediately following the upgrade, I began getting on 6 to 8 hours between charges.
I never did figure out what caused it, exactly, but I was able to fix it. I charged my battery completely, then let it completely discharge to the point that it actually shut down because it didn't have anything left to give.
I then left the device powered off, but plugged it into an A/C wall charger and allowed it to completely recharge before pulling it off the power supply.
Battery life immediately returned to 2 -4 days just like it was before the s/w upgrade.
It worked fine for another 8...

I recently had this happen to me when I did a factory reset on my Incredible. I was getting 15-17 hours of charge on the phone, then after the reset I was getting 6-8 hours on it. After a few full charge/discharge cycles, it's back to normal (aside from Angry Birds killing my battery now).
I've also noticed diminished battery life following a charge on a vehicle charger or an incomplete charge of any kind. Always better in a couple days, with good full charges.
I have a theory that there's something in a smartphone's programming that might see the charge on a battery incorrectly. Almost like the battery sees the battery charge at the incorrect level, and doesn't calibrate to the battery until a few charges are done.
