I bought the Forma in October 2018, and have been using it intensively since. The battery hasn't been the best, still manageable. But recently it has started draining much faster, like some 50% after 4 hours' reading, just reading, no wifi, light at 100%. I haven't changed F/W recently (skipped the last one).
Am I justified in thinking that would warrant an exchange?

EDIT: also it seems to take longer to recharge.
