Battery Charging

mjodotcom · #1 (**permalink**) 10-24-2009, 02:06 PM

I noticed that anytime I charge up my battery until my TP2 thinks its "full" (green notification light), that if I unplug the phone for not even 10 seconds and plug it back in, it continues to charge for at least another 15-30 min. Does this mean my phone is not fully charging? Anyone else seeing this problem?

Can you do this an infinite amount of times in a row? If so, I'm sure it just has to do with how often it's checking the battery levels or something like that, rather than an actual charging issue

i've noticed this too actually. checking it out yesterday and saw that after a full charge (green light) within 30 minutes i had it down to about 70% with only casual texting. today after sitting idle on a charger all night it's holding a charge much longer. since i've only had the phone for 5 days, i'm typically draining the battery to 0 and then fully charging it. think that's a bad thing?

What happens is once you reach a high battery level, HTC uses a technology called "trickle charging" It charges at a slower rate to perserve your battery's integrity for a longer amount of time.

This is a GOOD thing. It is supposed to happen. But you still shouldn't leave it charging all the time.

Yep, I was gonna say that once a battery indicates that it is near full capacity, an intelligent charger will go into trickle mode as to not damage the battery.

i'm familiar with trickle chargers, but they also have the intelligence to cut off charging once the battery has reached 100%. why wouldn't htc work that into the mix? just seems to me that if the phone is reading 100 percent and the light is green (i've seen it read 100 with the light still orange)... apparently full doesn't mean full.

Thats why I wonder if my battery woes have something to do with this. I have been through two batteries now, and my phone still won't make it longer than 16 hours with moderate use (even after uninstalling S2U2). Perhaps I am never getting a full charge?

I'm seeing the same thing, my battery lasts for maybe 16 hours.

I take the phone off the charger when I leave for work in the AM, after I get home (Light to moderate use at work 4-8 calls, Data doing weather, and some light internet usage) get home, and battery is at 30 percent. by the time I go to bed battery is down to less than 10 percent.

I do have S2U2 Installed, along with a bunch of other games (around 10), and a few apps (Internet Sharing, and HD Tweak) but other than that is is stock. I'm using HD Tweak so it disconnects my data after 1 min of non usage, and still battery life is bad.

Any ideas on what we could do to get better battery life?
