Killed the battery already.

i charge it EVERY night and cant get that at all...not even a full day

*shrugs* I can get a full day of really heavy use out of it... about 30% left when I get home. By heavy use, I mean browsing, music, phone calls, lots of texts, etc.

I honestly don't ever have the battery life issues everyone else does - the only device that was the exception was the Apache. My battery sucked just as bad with that thing as everyone else reported.

Yeah, I've noticed better battery life with my phones when I take the initial charge and play with it until battery is down to 10% or 20% (which is what I did this time), then run a full charge overnight, then just charge it every night or when it's needed.

On my initial charge for my Touch, I think it lasted like 10 or 12 hours or something. Then again, I played with my TPro for much longer

A few questions regarding some of the comments made:

Is a deep discharged considered when the battery is completely dead and then charged fully?

Also, from what some are saying on this thread, you should never let the battery die out on you. is that correct?

If, so would it be wise to assume that you should shut the phone off when you get the warning that the phone is going to die out?

Lastly, is it safe to leave the phone charging overnight? It seems as if some are saying you can overcharge the battery.

Thanks.

I forgot to ask, what kind of battery does the Touch have, and can it be used with the Pro?

I've used many li-on and li-po batteries in various devices. Even though this information is for using li-pos in R/C vehicles, the same general principles apply that have been mentioned in previous posts by PPCGeeks members.

I've personally had a 2s li-po battery explode into a flaming ball of fire because the manufacturer labeled the capacity wrong and I charged it more than 1C. The battery was puffed up and hissing. I knew what was going to happen and luckily it exploded when I was opening the outside door of my house instead of while I was in my room. It can seriously burn a house or car down. I also realized that when a cell goes below ~3.2V in a battery pack, it ruins it. This happened to a 3s4p pack I was using even though I balanced it while charging, the setting on my voltage cutoff got messed up. When I recharged the battery, that particular cell was bloated and wouldn't balance out. Granted, some of this doesn't apply to a cell phone but it shows how serious it is to take care of your li-on battery.

Here is what I usually do with my batteries:

1. I make sure they're fully charged when I received them.

2. I never deep cycle a lithium battery. This is a no no. They aren't ni-cd or ni-mh batteries. If you've ever used lithium batteries on R/C vehicles, you know that you absolutely must have the proper charger which in this case, is supplied with our phones. For charging my R/C batteries, there isn't a cycle option on the charger for lithium batteries; it's only on ni-cd and ni-mh battery options.

3. I find it best to charge the battery whenever possible but not for a brief period because it'll get hotter when doing a short charge burst, then using the device. Heat is an enemy of lithium batteries. Don't leave it sitting in a hot area or it will catch on fire.

4. If you're going to store a battery, leave it at a 40% charge. You can stick it in the fridge but don't put it in the freezer!

Even though some of the information is repitive and the article applies more to R/C batteries than cell phone batteries, the general idea is the same. I'm glad that our cell phone batteries are safer and more forgiving than R/C li-pos because I don't want to charge my cell phone in a fire suppresent bag so that in case of a fire while charging li-pos, it doesn't catch everthing else around it on fire because of getting too hot. It's really easy to take care of lithium batteries and they're not any more dangerous than ni-cd or ni-mh batteries when you take care of them properly. It's when you don't know what you're doing when you can run into disaster.

You won't be able to discharge the batteries in these phones deep enough to do much harm. They have internal circuitry that shuts them off if they get too low.

Also, there isnt much danger of these bursting into flames or anything, their internal circuitry also monitors charge level, voltage, temperature, etc to make sure its always charging at a safe current level.

That's why I mentioned that the cell phone batteries are more forgiving and I realize it probably won't catch on fire. There is a major difference between a cell phone battery and a battery used in a R/C vehicle. Some of the info. from that article isn't relevant but charging and taking care of them is similar. Personally I don't recommend running it down until the phone shuts off but that's my opinion.

is it bad to charge it overnight? put it on around 10pm or midnight ish and take it off the next morning.

thanks..

I recall my Mogul giving me about 5 to 6 hours of good heavy usage before it died.

[saqer]

No, not really, but the idea is keeping ur phone docked/charged can generate extra heat. Whether or not that heat will lower the long term life of the battery is still controversial in my opinion, so for me just set the thermostat to a lower tempertature. It's good for getting to sleep quicker too.

On a different note, I also think that extended batteries are good in 2 things:

1. Increased mAH
2. Less charging frequency. So charging an extended battery once every two days is better than charging a standard battery multiple times a day or even just once a day.

That's why as soon as HTC/Sprint release an extended battery for the Touch Pro. I'm getting it!
