9. Lenovo P2
An amazing battery for a low price
Weight: 177g | Dimensions: 153 x 76 x 8.3 mm | OS: Android Marshmallow | Screen size: 5.5-inch | Resolution: 1080 x 1920 pixels | CPU: Snapdragon 625 | RAM: 4GB | Storage: 32GB | Battery: 5100mAh | Rear camera: 13MP | Front camera: 5MP
There's one reason to buy this phone: a genuine, actual, real two day battery life. Not in optimum conditions or if you're a light user... it'll just keep going and going for two whole nights.
The phone itself is very cheap as well, making it our top budget buy, and while some of the specs are downgraded to hit that price point (the chipset won't please everyone and the camera isn't the best) we think it's worth it.
Not the best out-and-out Android phone on the market right now, and it is heavy thanks to the larger battery - but it's kind on the wallet and will mean you spend far less time tethered to a charger.
