Battery life has been reasonable for me since the day I got it. And that was the first day it was available. But just within the last 36 hours, the battery drains in a matter of 3- 4 hours, and when I put it on a charger, it takes forever to gain any charge. Plugged it in 2 hours ago and its only climbed from 9% to 24%. Thats way slower than normal. Bad battery? Its not that old.

They can't go dead for no reason, but they do go dead for reasons that might not be apparent. :p

I assume you've used Watchdog or something to make sure you don't have any CPU hogs out there, and you've checked your battery usage charts and not seen any wild swings away from display to other things, correct?

If that's the case, then it's quite possible that the battery is simply wearing out. Maybe it got too warm one too many times, or was completely discharged or bump charged too many times. Hard to say for sure, but I've had Li-Ion batteries go kaput after 6 months, even good-quality ones. Then again, I've had cheap crappy ones last for years with only the expected linear drop in capacity. It's a combination of the quality of the battery and how it's been treated, and sometimes mistreatment is unintentional and done unawares (leave your phone in a jeans pocket while walking around on a nice hot day, your battery is going to get a little warmer than it likes to be).

If it's still under any sort of initial warranty, I'd go into a Verizon store and see if you can easily get the battery swapped. If it's not, you can still ask nicely if they'd please do a courtesy battery replacement for you.

Failing at that, the extended life battery is apparently on sale for $25 at the moment. Buy yourself an early Halloween present.

Batteries can go bad prematurely... and so can chargers. Try to test the charging on two different chargers to see if is charges any faster.

If all else fails, the battery is under warranty and can be replaced. Call in and ask Tech Support about their current battery warranty policies, as for some reason I forgot them lol.

Well I disabled 4g and most of the auto sync functions, still pretty useless. Been on charger for over 5 hours and still only 65%.

Dont think anything is hogging the battery, cell standby is the top battery drain today at 30%. Not even using the phone much at work. I would have boughtt an extended battery a long time ago if it wasnt for my extensive use of the phone in my car mount. Extended battery wont fit into the dock! That is a real bummer. Between GPS, Pandora, Sirius XM, and of course using the phone as a phone, the windshield mounted car dock with an AUX jack running into the stereo system is easily the most used accessory of my phone. Guess I'll be stopping by the Verizon store tonight

Is the phone getting pretty warm. If it is taking a long time to charge, and draining the battery quick, then there is a high load on the battery. And the battery/phone should be getting noticeably warm.

If it is NOT getting warm, then I would suspect you have a charger issue, and you simply aren't getting much out of the charger.

And install the battery monitor widget. It will indicate current into and out of the battery to let you know more.

I had that problem about a month ago... phone was taking forever to charge. I was able to fix it by recalibrating the battery and switching kernels... phones rooted. It didn't survive too long after that though.. a few weeks later my phone wouldn't charge past 78-80%... had to get a replacement. It was caused by using a bad charger which originally gave me a warning that I was using an incompatible charger and that it may cause damage to the phone... well, it did.. it was a car charger I bought off of ebay.

Hmmm.... charging battery while in car dock, potentially in the sun, and using phone heavily equates to a very warm, bordering on hot phone/battery. Heat is a big enemy for batteries. Bet that's what killed it prematurely.

Any battery can go bad at anytime. Phone. Car. It happens. I had a battery go bad on an LG a few tears back.

Well, I have several chargers I use regularly. Home, work, and car charger. Have used them extensively with no issues. Anyway, rebooted and charged for 9 hours, now it seems to be back to its normal self. Weird.

I would not trust it. See if it charges faster on any one charger (home or work... the car charger will be lower amperage and so ignore that one), and see if the battery dies faster after using any one charger. If one of the chargers is bad and causing damage, you may need to get the battery and chargers replaced. The battery can be replaced for free by Tech Support under warranty... the chargers often times only have a 30 day warranty, so you may be on your own there.

The battery is covered for a year. I had this happen with my Blackberry and the battery and the charger were both bad. They replaced them both.
