Downside: the knock Code Mode [I chose this mode lock but other alternatives are available: PIN, graph] is generally efficient, but sometimes slow to relax: gender 10% of the time, I have to type in a 2nd time the code, the phone has not responded to the first attempt.
Consumption very reasonable battery. It takes the load 3 to 5 days. Well, I do not play it. Major uses: phone, msg, Twitch streams (with or without Chromecast) web.
In short, nice to this unit. I hope him a beautiful career as 4 years of my HTC Desire, retired but indestructible.
