HELP. need to know. TP2 Battery longevity

[jkraze]

ok serious question here because i would like to know if by plunging in the charger and keeping the data on all night ruin the battery longevity? i understand we must train the battery by letting it run out of juice and recharge but im curious to know if by leaving it plugd in at 100% ruin it.

dont lithium Ion batteries tell you NOT to leave it plugged in all the time? i know my laptop says not to... i do have a TP1 that stays plugged in 24/7/365 for tethering, but i dont use the phone for anything else so it doesnt reallymatter if it detroyes my bettery life

thank you for the reply

I think once it's plugged in and gets a full charge, it stops charging the battery and then runs off AC power.

yea i thought about that also but didnt understand how come a laptop can run without a battery and just ac power and tp2 cant..but even so if the tp2 runs off pc power i think the juice flowing from the ac through the battery would still drain it a little... talking like .0000001 or something but in time increases..im not sure though.

Thats a good question.....

I believe that on the phone (newer phones in general probably), some of the cicuitry is in the battery from what I remember. I would imagine that increases reliabilty, should someone fry their battery from using a poor quality after market charger or something likw that, replacing the battery will replace that circuit that regulates the battery.

That might be why newer phones dont have big ol stupid transformers for chargers anymore either, at the same time most laptops have big transfors inline on the power cord, while some have them built into the laptop itself.

As far as using data and getting power off a PC, the thing to do would be to get a program that measures your battery current, they'll tell you how much juice is coming in and how much is going out. Not all USB ports and phones are created equal. I have an old computer that I built in 2001 (non usb 2.0 I believe) I also have a long USB extension tied into it because I use it to play media on a TV, so having a long USB makes it conveinent. The downside is the extra length creates resistence, which decreases power (so to speak) which will cause the the TP2 to give me a warning telling me that the charging current isn't enough if I've got teahtering and maybe another program running. Basically if you've got more power going out then in.

I think in that case, yeah your probably decreasing battery life. But again batteries are cheap, I didn't do ANYTHING to try and maintain the life of my old mogul/6700 and I had that phone since new, that battery lasted me unitll the phones death, which was around the time the tp2 was coming out. Not ssure if the battery had gone bad at that point, but by then phone had enough other problems for wear and tear that it didn't matter anyhow.

Yes, I believe that is absolutely correct. Battery management on the tp2 is better than it was on the tp1. I think that it doesn't charge the phone 100% either just in case you are constantly taking the phone on and off AC power.

Also, I wouldn't worry about it, because batteries are cheap.

Thank you for explaing that bobturismo, i agree with the resiesnt with longer cable but wouldn't that be a super long cable in order to lose that much juice. according to omls law

Here is the battery guide. But from what I have been told they last so many "charge hours" so if you charge it 10 minutes every hour for a day, you only took 2 "charge hours" off it's life span. If you drain it and it took 2 hours to charge you still used 2 "charge hours" off it's life span. So don't be afraid to keep it topped off, it works better that way.

such a touchy subject.. wish i was a battery expert so i could answer this question 100% .. :/
