We were starting to think that JiaYu had forgotten all about the thin version of the JiaYu G4, but a recent forum post shows us the phone is very much alive and currently undergoing final tests.
Currently the only version of the JiaYu G4 available is the thick model with standard 1.2Ghz MT6589 CPU, 1GB RAM and large 3000mah battery, but Jiayu always promised that a more powerful Advanced model (seen here) would go on sale along with a thin version of both phones.
The only differences between the thick and thinmodels are the body thickness, size of the battery and about a days worth of usage! The 3000mAhbattery version of the G4 easily lasts 2 days of use, but engineers at JiaYu say the thinner option gets just 20 hours of use.
Gizchina News of the week
20 hours is more than enough to get the average user though the day, but those of you who spend your free time gaming might be wise to by the 3000mAh model. It should also be noted that the phone tested was a 1GB RAM, 1.2 Ghz version not the more power 2GB RAM MT6589T Turbo version.
More details and photos of the test can be found over on the JiaYu Forum. Thanks to 2PointOBoy for the tip.
Is 20 hours enough for you? Let us know in the comments below.

Shocking, given that the A7 is meant to be a more power saving chip as compared to the A9 and the A15 counterparts.
My HTC Sensation had a standby time of 59 hours (I joke you not) and it only had a 1500 mAh battery.
I feel disappointed really :\
Standby time does not equal usage.
I can smash a battery on pretty much any phone flat in a few hours, even though it may do a week on standby.
20 hours of usage is pretty decent if you say.. have 1 hour of web browsing, 1 hour of calls, 1 hour of video and 1 hour of audio, the rest of the time just background polling ect.
I guess, but Even so, that 59 hours was me using the phone, surfing and whatsapp messaging.
20 is decent in that sense, but I’m not sure if I should be expecting more out of an A7 Chip.
Ehh, I don’t really know what good battery life is like, i live in an area where reception is between low and non existent, so all phones and phablets get poor life. My Note II gets just over a day standby :S
Hmm. I’m using a Note 2 as well, and I pull about 30 hours on a normal day (with plenty of Whatsapping, surfing and gaming), and about 40 hours on a very dull day, with minimal whatsapping and surfing, no gaming.
Yeah, signal strength plays a real big part in the secret to having a good battery life, but I think the other lot really boils down to how well the engineers programmed their Kernel, and the “lightness” of the ROM.
I extend my battery life installing a Custom ROM and Kernel onto my Note 2, and heavily tweak the Kernel’s voltages to the bare minimum needed to run stable, which in turn makes my phone run cool and draw less power.
It would be interesting to see a benchmark comparison of power draw vs performance with the MTK6589 vs Qualcomm’s new Snapdragon 400 Quad Core A7’s. Assuming they then run the same fabrication process, it’s easy to see which has the more efficient Kernel/ Radio.
And I’ve gone on and ranted :\ yeah.
I ended up breaking the USB socket on my note from plugging/unplugging too often 🙁 lucky replacement parts are cheap.
Well, since the a7 core is 100% the same [if same process/lithography node(because they are arm’s IP)] it would just come down to things like kernel, memory interface and gpu. I *think* the qualcomm has an external radio, whereas the mediatek has one built into the SOC, so if you just measured SOC power consumption the mediatek would lose.
Radio NVRAM configs and kernel play a big part, and since mediatek is very closed with their chip information, i don’t think there is much we could do.

I wonder how you fit 40 hours in 1 day.
