That's my usual method (early gta02a5)

Use the charger not USB. The charger gives 1A instead of the 0.5A from USB. If 
it still has trouble, disable the GSM and/or dim the display. GSM occasionally 
demands high current so you may just have been unlucky when you were swapping 
the battery. The display backlight at full brightness uses as much current as 
the rest of the phone put together, so dimming it can save a lot of current.

Other than using the charger I've never needed any tricks. I've probably used 
every distro but the debian-based ones.
