Huawei just announced the Ascend Mate. It has a gigantic 6.1" 1280x720 HD IPS+ display. Is it similar to the Nexus 4 and LG Optimus G display but only bigger? The other big number is the huge 4050mAh battery. That's almost as big as the batteries in many 7" tablets like the Nexus 7, Playbook, Kindle Fire, etc.
Powering all this is a custom Huawei processor with a 1.5 GHz quad-core Hi-Silicon K3V2 + Intel XMM6260 GPU. I've never heard of the Intel XMM6260 but the K3V2 is a Cortex A9 design so it probably won't be as fast at non-graphic duties as a Quad-core Krait.
Other specs include 2GB RAM (very nice), Android 4.1 and 802.11 ABGN dual-band WiFi. Like the Ascend P1 and D Quad XL it's listed as having penta-band support. Hopefully they'll bring out an LTE version for North America.
Software-wise there's a one-handed mode which looks familiar, limited multi-window support (reminds me of the Xperia T). Guiding wizard is Navigation that uses the camera to overlay the directions over what you actually see. I've seen Navigation with augmented reality before but it was only a demo. I hope it works well because it's a feature I've been waiting for.
The specs are interesting. It's got the biggest screen out there but it's not a 1080P display which makes me think it's a mid-upper range device rather than a range topper.
Anyways, it looks like a great device for the 'mine is bigger than yours' crowd. Can't wait to check one of these one and lord of the poor saps squinting at their Note II displays.
I tried Clean Master app as suggested but didn't improve much. It was also suggested to reset to factory settings and that worked. Battery life is as before. Just back up pics and things you want to...
