The new iPad battery life is too short. I left the hotel with the iPad at 100% charge.  All apps were closed. When I got to airport; iPad was showing 95% - I then turned on WiFi to flight plan as the overseas connectivity on cellular mode was hanging up and not useable. By the time I had finished flight planning with the iPad and was heading for the aircraft; it was showing 82%. I used it for cockpit set up and briefings and taxi charts discussion. At pushback it was showing 71% - now in airplane mode. At top of climb I noticed the iPad was now showing 58% - then; buy mid Atlantic it was down to 42% - The only apps open were FM; FOM and Jepp FD Pro.I do not consider the iPad is useable as an alternative to Jeppesen documents. I also urge a return to the cockpit of the FOM; FM and WOM in paper form. I was getting very concerned about losing ability to consult the company publications for reference purposes. This is not a viable alternative to paper pubs. Sadly submitted.
Air Carrier Captain believes that the iPad battery life is too short for international flying and laments the demise of paper charts and manuals.
