Great Review, but the stamina of the battery really seems to be the problem...Would Juice Defender help?


I read that the battery level reported by my current firmware is pessimistic and had been upgraded with latest firmware. In add, as I said, I think that current applications are not optimized for RK3066, and uses more CPU than an optimized software (GPU decoding for video). Dice player or Mobo player with dedicated plug-in should be great for video decoding.

My phone: Galaxy S2, Sony Xperia Z Ultra 4G
My tablets: FNF iFive X2 16Go, Window N90

Is there any opponents for real racing 3? ?

Can it be solved by a firmware?

CONS:

* a periodicaly an error message "android.process.acore has been stopped". Perhaps solved with last firmware ?

I had the same problem
but new firmware 20120711-ZZ solved this problem

The really big problem is long charge time - more than 7 hours when battery life only 3 hours 30 minute

Maybe, maybe. So far, no one can say.

Perhaps it depends on the charger. From standart cheap package is usually very poor quality.

At least they can make a firmware to solve this or put usb to charge it. I really like the tablet but the real down fall is the battery stamina.

My N70 has been delivered with a 5V 2A charger. As the battery is a 3,7Ah, it should take less than 2 hours to fully charge it. I didn't make a full charge yet, but it takes less than 2 hours to charge from 40% to 100%.

I would like to update my firmware, can somebody reply to my question ?

How should I proceed to update the firmware ?

* I've downloaded and installed Moborobo. I run it and my N70 is correctly connected.
* I've downloaded and run SuperOneClickv2.3.3-ShortFuse Modded and I can root and activates SuperUser rights
* I've downloaded lastest official firmware (20120711). It's a .img file. And I don't know to use it to upgrade my N70....

Firmware update attempts (N70双擎版-4.0-20120711-ZZ.img):

With Android maintenance boot:
1) save firmware on SD card, rename it update.img
2) Boot in maintenance mode (power + volume up buttons, long press)
3) With menu (power + volume up buttons), select "update rkimage from /sdcard" and press power button

=> FAILED, "not support firmware"


With RKBatchTool.exe, found here: Firmwares & update tool
FAILED!
2 problems:
=> I cannot install supplied USB driver for my N70 (Windows 7 64 bits, french)
=> RKBatchTool.exe is in chinese even if I select english in config.ini file. The program crash if I try to load my .img file.

:(

Files taken from original yuandao website
http://yuandaocn.com...309888-1-1.html
3. Micro USB cable
4. N70 Dual Core

1. Extract the flash tool with winrar
2. Rename the chinese characters on the image file and flash tool folder to non chinese. (it gives me error on the flash tool when i don't do this)
3. Power off you device
4. Connectr the USB while holding on to the vol up button
5. You should get a driver not found error, if you don't Start -> Run -> devmgmt.msc
6. The drivers is located in the Flash tool RockusbDriver
7. Choose install anyway if there's a no signature error
8. Run RKBatchTool.exe
9. Click the bottom left most button to change the language to english

Thank Kaggy, it works perfectly. FYI, step 13 takes less than 2mn with my N70, and step 14 about 2mn too.

Battery Test: about 3:35 for video playback
Wifi On, Brightness Max, Volume Max
Test ran on 1080p AC3 MKV file

Doesn't run 10bit, Hi10 or whatever you call them.
Lots of artifacts when playing Hi10 video.

The battery life isn't awesome but i find it fairly ok.
I think games will drain faster

Can't charge with device switched off, when connected to power it starts up the device.

I can agree with you Kaggy, received mine yesterday.

Starting with a lot of craches with the factory firmware, the N70 is running fine now after i updated to the newest firmware.
Compared with the aurora II which i sold, the N70 runs more smooth and is even a bit faster, and the screen is almost equal to the blackberry playbook, which is in my view one of the best you can buy.
Score in vellano benchmark 1675, above the transformer prime and one x, and in quadrant benchmark above 4000.

On order, nothing, and am i am finished with Chinese cpu's, i prefer my exynos devices.
Favorites, in order of use, Samsung galaxy note 8 inch, Ramos W42, Ployer Momo11 quad exynos 4412.
Sold last months, PiPo U1, Teclast P85, PiPo S2, Teclast P85HD, Cube mini U30GT, Yuandao Vido N80IPS, Ainol Novo 10 Hero ii: very bad, Ployer Momo12, Onda V812, Yuandao Vido N80 RK3188, Teclast P88, Google Nexus 7-8Gb, PiPo M8pro RK3188, Chuwi V88 RK3188, Samsung galaxy tab 7.7, Ployer Momo8 IPS, Yuandao Window N70, BB playbook.

The stock video player.
I doubt the difference would be great even when you use another player.

Charging is really slow thou, it took around 5-6hrs.

>>I doubt the difference would be great even when you use another player.

Do you mind trying this test with MX Player in software decoding mode (there is an option for that) and with hardware acceleration (there is option called "force GPU rendering" in Android settings, as far as i remember) disabled? I just have an idea that GPU is eating up most of the battery (user lubomyr running test now with CPU frequency set to 252 Mhz and for now it seems to show same results - about 3 and a half hours), so I just want to check if there is a way to avoid high battery drainage in casual (internet, reading etc) usage of N70).

When playing video, most of battery is drain by the display, especially if brightness is set to maximum. In add, hardware acceleration (video decoded by GPU) consume less battery than software decoding.

MX Player allows SW (software) & HW (hardware) video decoding with push of on-screen button. Software uses CPU. Hardware uses GPU. Should have better battery life with HW decoding but have not tested this out to make sure.

Stock video player likely uses SW decoding?

*MINIX NEO X5 (RK3066) - OK. Not fun because uses mouse cursor.
*YUANDAO N80 DUAL (RK3066) - Very good
*CUBE U30GT (RK3066)- Defective; buttons broke in 2-3 weeks; Bad quality control!!! I will never buy a Cube again!!! - Very good while working
*WOPAD I7 (RK2918)- About OK. Sluggish because has weaker ARM chip (RK2918) & less RAM (512 MB).

It seems good, but brightness at 20-25% must be too dark.

As for me not dark.
Default brightness 35-40%.
IPS-AFFS screen have good brightness also on low values.
