My guess is that you have a pile of apps running that are killing your battery usage.

I've had my Eris and prior to getting the 2.1 update, it would last about 2 days... call it 40 hours of total up time.

Since 2.1, it barely lasted 18 so I tried an experiment. I found that my Eris wasn't closing apps properly. So yesterday, I made sure that I had a full charge in the AM, and around noon and then again around 10:00 pm, I ended tasks on apps that weren't closed out properly. Woke up this AM to about 1/2 battery and am hoping that it goes for the rest of the day or until the drive home when I can charge it again.

This will now become part of my routine until HTC can fix the closing of applications.

Since 2.1 I can hardly make it through the day and I don't use my phone much at work. Sucks hope something can be done. Did 2.1 do more bad then good?? sheesh.

 

But what does a new handset give you? You mean to go back to 1.5? Or do some phones work good with 2.1? I like the new things 2.1 added but at what cost.

 

Your battery is most likely just bad or something else is going on. It shouldn't have anything to do with how you treat your battery. I never treat my batteries "nice". I don't charge them properly when I first get them, I don't discharge them properly, I never EVER worry about how or when I charge my battery or anything like that and mine is just fine.

I've never worried about the batteries in any of my previous phones and I've only had one problem from a battery than wouldn't last long, but that was after I'd had the phone for 2 years.

 

ya.. i feel like a d-bag. how do i go back to 1.5?
