One year after the purchase of my Nexus 5, the battery held until noon while I rechargeais overnight. After careful consideration, with respect to mixed reviews on this battery, I still bought. To install the battery, it takes 5-10 minutes to be ready, which is quite correct, and nothing complicated.
It is now two days that I used, and I rediscovered the pleasure of not having to plug in his laptop 2-3 times a day. The battery stand the day. Now see with time if the duration of battery life is decent.
