Uh oh. So it looks like T-Mobile’s Windows Mobile-based Wing handset might be having some battery troubles. Wing owners have been quietly receiving replacement batteries in the mail. The new batteries are manufactured by Celxpert, which marks a departure from the original Dynapack-sourced juice packs. The new batteries are accompanied by a short note that reads:

T-Mobile and HTC are providing a replacement for the T-Mobile Wing battery made by Dynapack at not charge to you due to rare occurrences of the battery overheating.

"Rare occurrences", eh? Sounds a bit ominous. Has anyone out there experienced any issues with the Wing battery? Let us know!
