The Asus' chunky 1300mAh battery gives the P750 a reasonable run between charges. We only found ourselves reaching for the charger every other day even with fairly regular use of the Wi-Fi and – very efficient - GPS receivers. Certainly it was significantly better than the HTC Diamond, a handset that had battery inadequacies which in retrospect we perhaps dismissed a little too lightly.
Asus claims five hours of talk time and 240 of standby in a 3G signal area, which didn't prove to be too wide of the mark, the call timer recording four hours 38 minutes of usage before the battery curled its toes up. A full charge also managed to support for the GPS receiver for the best part of six hours, which impressed us.

Power and wired connectivity come courtesy of a mini-USB port and while Asus get a pat on the back for including a separate headphones jack it also gets a kick in the dangleberries for making it 2.5mm rather than 3.5mm.
Call quality was more than acceptable, as was signal reception, though since the screen lacks an “H” icon you are never sure if you getting HSDPA or just Plane Jane 3G.
Verdict
Competent is the world that springs to mind when looking at the P750. It doesn't really advance the science of smartphones but it's a robust and usable example of the breed and can be picked up for between £300 and £350. Assuming the one you buy actually works with a Micro SDHC card and assuming you're happy to cough up a few quid for CorePlayer, Mobile Shell and the like, you will end up with a not half bad handset that should last the course.

@H
Thanks for that Richard.
We are starting to think that our handset was perhaps non-UK standard or an early model as we didn't get the H signal icon in any of the places we expected it (and where we had it on a K850i and HTC Touch Dual, all three using T-Mobile sims which we swapped about to double check). Also the user guide to all the icons that can appear on the screen also made no reference to the H icon. This may explain our MicroSDHC issues too.
Looks boring, sounds interesting
Finally, someone manages to combine 3G, WiFi, touchscreen, a solid keypad and the ability to take SD Micro (albeit not necessarily SDHC) into one device. Wonder how much weight dropping the mediocre camera would have saved, though...
I get the 'H' all the time
Wrong on no 'H' icon. You're not getting HSDPA. This is a problem with providers. I had to fight with T-Mobile techs to get them to 'activate' my 'enabled' HSDPA. This was after fighting with the Customer Service agents who swore I had to pay another £10 pm to get it.
If you're on T-Mo, you show 3G until an actual data transfer starts with GPRS. Then if the signal has 3 bars, it will switch to H.
I get the 'H' on P750 with T-Mo at my desk on the 9th floor at Canary Wharf, and speeds from 900K to 1.3M bps.
