eh que no me lo he inventado yo...segun comentan en xda-dev es la respuesta de htc...
Aun asi tiene su lógica, las celdas no se cargan homogeneamente en una carga normal,y segun comentan el cargador del movil en este caso no tiene balanceador de carga... de hecho después de trastear con algun cargador de baterias de estos avanzados de 300 euros para aeromodelismo y demas, los ciclos de carga que hace para las de litio son bastante curiosos y raros. y suelen mostrar en pantalla el % del balanceo en las celdas.
aun asi os dejo el post original:

Dear XXXX, HTC and Sprint are taking steps to improve observed battery life. HTC is developing a number of handset software optimizations that are expected to increase device operating times. These updates are expected to be available as part of software pushes scheduled for later this summer. As with any software development effort, we cannot provide an exact date. Additionally, Sprint is working to optimize 4G network settings to improve battery life for customers in 4G markets. I will be happy to go over various setting with you that will help extend the battery life. Traditionally WiFi, GPS, Bluetooth, and display brightness all greatly impact battery performance. With Android 2.1 another feature that can kill your battery are the Live Wallpapers. If you’re using Live Wallpaper just turn if off. Adjust the Brightness of the display (Menu | Settings | Sound & Display | Brightness). By default it is set to auto adjust but you can manually adjust it down. Consider adjusting the display timeout (Menu | Settings | Sound & Display | Screen Timeout). The default value is 1 minute but you can reduce it to as low as 15 sec but 30 seconds. By default your HTC Incredible vibrates every time you press a key. Turn it off by un-checking the box ‘Vibrate when typing’. Menu | Settings | Language & Keyboards | Touch Input | Text Input | Vibrate when typing. If Facebook, Twitter, MySpace, Email, App Updates, or many other things are constantly popping notifications, consider turning some of them off as notifications do impact battery performance; This is done in each app. To also help with Battery Life you can do these steps exactly: 1) Turn your device ON and Charge the device for 8 hours or more 2) Unplug the device and Turn the phone OFF and charge for 1 hour 3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, we have tested this on our devices and other agents have seen a major difference as well. HTC has received some reports regarding this issue with the screen seperation, and are currently analyzing the potential causes. Most customers are not reporting any issue related to this problem. The issue appears to be cosmetic and should not affect the operation of the device. Additional information will be provided after we finish our investigation of the issue. If you have any other questions or concerns please Reply back to this email or give us a call at our HTC Technical Support Line, 1-866-449-8358. I want to thank you for contacting HTC.

This battery charging regimine is a one time operation, if you need to do this more than once a month, I would talk to Sprint about a replacement battery, but with the batteries we are looking into the issue further. We are not sure why this works, we like our customers have the HTC phones and were looking into forums and found this and it worked on all of our agents batteries, they all gained about 10 hours of battery life with regular use. We have also, tested how long the batteries take to charge and yes, this battery takes about 4 hours to charge, we are looking into this, but it is not an issue that will harm anything. You should be able to charge your battery while sleeping and you should not have a problem with the battery lasting all day, but again we are looking into the battery situation. With the Micro USB cables, most should work, but we recommend HTC Micro USB cables.

y otro post sobre el tema inicial, donde podeis ver que segun mucha gente si que funciona y que es problema del balanceo de carga, como en las baterias de modelismo RC...
http://forum.xda-developers.com/showthread.php?t=701567
si os fijais, varios hablan del tema de balanceado de la bateria... y del reseteado del ciclo de carga, apagando y encendiendo el movil. De hecho tambien comentan que sin la carga balanceada, el movil pasa de 100% de bateria a 90% en muy poco tiempo.
