The EU wants all smartphones in the future to standardise on micro-USB ports for charging to avoid millions of phone chargers going to landfill every year. The E52 obliges as the micro-USB port handles both syncing and charging duties.
Most of the E series handsets have been very impressive performers when it comes to battery life and thankfully the E52 doesn't change this trend. Nokia quotes a talk-time of eight hours and standby time of up to 23 days, which seemed pretty conservative in comparison to what it achieved during our test period. We used a range of features such as the GPS, Wi-Fi and HSPDA downloads over a few days and found that it managed to keep running for three days before it needed a recharge. With most smartphones you're luckily if you get a day or a day and a half from their batteries, so the E52's performance in this regard is highly impressive.
What's more, the phone's call quality is also first rate, but then with Nokia phones you kind of expect that. However, the E52 actually includes noise-cancelling technology that tries to cut down on background noise picked up by the mic while you're on a call. It works really well, although obviously there's the odd squelchiness that can be heard every now and again when there's a real racket going on around you and the noise-cancelling is working over time.
The E52 doesn't exactly break new ground. It's got a pretty standard candy bar layout and uses a normal mobile phone keypad for text entry, but perhaps that's the point. This is a smartphone for those people who don't really want a smartphone, but need some of the extra features they provide like good email support and the ability to view and edit work documents on the go. The fact that it does this while still offering great battery life and brilliant call quality is just a bonus.
