So I recently bought an extended battery for my evo. I've been having some problems though. I charge it & it says its fully charged but it starts to come up on my battery widget that its going down quickly. with library usage. like yesterday I fully charged it at 5. Left it on overnight. Then had moderate usage with the music app. Dies around 5. Ive heard of it dying in about 20 hours with heavy usage... Anybody know the prob?
Extended battery problem...

It doesn't even tell you how man mAh it has?
It's definitely not an HTC battery, then. No matter. I only wanted to know so that we can get a baseline on what to expect out of the battery, as there was a thread somewhere that tested the various batteries from different manufacturers to determine how they actually compare to the stock HTC battery. But I can't find that thread, so can't check anyway.
The more important part of my first post, which you seemed to have ignored, is to calibrate the battery to your phone, so that you can actually get a full charge out of the battery, and have accurate readings on your phone.

Battery Calibration Instructions
The credit for Method #1 goes to Aaronw143 and coiledwire. Method #2 is thanks to HTC and many others who quote them. Method #3 is thanks to HipKat and others on XDA. Method#4 is courtesy of Marosige's thread on XDA.
These methods are meant to help increase battery life. I take no responsibility if it doesn't work or your phone explodes, you get eaten by aliens etc.
Method #1:
1) Plug in and charge until LED turns green.
2) Implug for a few minutes, then plug in again until green.
3) Check battery stats to verify it says that the battery is full (while still plugged in).
4) Reboot into recovery and wipe the battery stats.
5) Boot fully into phone, then unplug.
6) Use phone until it shuts itself off. Ie: until it dies!
7) Turn on again and again while taking the battery in and out of phone. Keep turning on until it won't even power up for a second.
8) Keep phone plugged in until fully charged (LED turns green).
9) Turn on and use normally for a few charge cycles.
Method #2:
1) Turn your device ON and charge the device for 8 hours or more.
2) Unplug the device, turn the phone OFF and charge for 1 hour.
3) Unplug the device and turn ON.
4) Wait 2 minutes, turn OFF, and charge for another hour. "Your battery life should almost double".
Method #3:
1) With the phone on, fully charge the battery (until the LED turns green).
2) Once the LED turns green , unplug the charger until the LED goes off.
3) After the LED goes off, plug the charger back in.
4) When the LED turns green, power off the phone.
5) With the phone fully powered off, unplug the charger.
6) Wait until the LED goes off, then plug the charger back in until the LED turns green.
7) When it turns green, unplug the charger again and go to step 5.
8) Repeat steps 5 through 7 ten times. This may take anywhere from 30 seconds to 30 minutes per cycle. It typically takes only about 1 minute, though.
9) Reboot into recovery and wipe battery stats.
10) Reboot and enjoy!
Method #4:
1) Download the Battery Calibration app from the Market and follow their instructions.
2) That's it. Seriously!

I purchased a seidko (spelling?) after market 3500 from a third party quite some time ago. my phone started having reboot issues. It would especially when using mobile network just shut off, and not turn back on with out shutting its self off again. I called sprint, jumped threw some hoops, still kept shutting off. Once shut off, it would not power on, unless plugged into a charger, no matter how much of a charge the battery held.
Sprint sent me a replacement phone. While waiting for the phone to arive, I saw online that some people were having problems with aftermarket batteries. Just to see if it would help, I put the factory 1500 battery back in the phone and it worked fine. I notified sprint, and sent back the replacement.
Could the problem be that I did not calibbrate my batery? or was it infact just a different problem with the battery causing my problems? Are the problems I described above similar to problems people have when their battery is not properl calibbrated?

Guess ill just put in the replacement battery, calibrated it, and let you guys know if it still shuts my phone down.
Well to update the situation, the Amazon seller claimed it was a seido, turns out it is a cheap knock off. I got the batter out of my closet, and it was swollen, and buldged out from back to front, and will not fit in the phone. I made no attempt to chare it or even turn the phone on with that battery. However 2 Evo batteries will fit in the back plate. So you can have one fully charged on standby, and the other hooked to the phone for emergency use.

I got a 3500mah battery from amazon for $6.50 with the extended back cover I notice it doesn't fit the EVO so I stuck a piece of paper in between the space so it wouldnt move and its doing okay so far O
Don't cheap out. But a quality battery and you'll have ml problems. I bought the sedio extended battery.
Tazman, thanks for the information. - I have the Seido 3500 Mah battery too with the same problems described above. I have since root my phone, and once you have done that you can download the Battery Calibrate application from the Play Store. I've used it a couple of times but it didn't fix my problem. I'm going to run through method #2 since it's from HTC and get back with an update.
In summary, I like most people with EVOs want to have a charged phone before leaving the house, so you probably stick it on the charger when you get home regardless of the charge remaining on the battery. I'm assuming this causes some bad cells over time like the older batteries use to do. Nonetheless, something I found intriging as I proceed through the steps, after 100% charge, and power down and charge for an hour, the phone was 80%. This tells me the calibration must be off. Ill keep you and everyone posted as I complete the steps.

Not the Li-Ion batteries. They can be topped off as you described and not be affected too much.
