Adjusting the volume levels in the engineer menu MTK * # * # 3646633 # * # *

Max Vol is the same for the whole subsection, as a rule, 150 (you can change 0-160 - it changes if you select the Media item in the subsection).
If in a submenu, for example, Audio - Normal - Sph, the general level is not accessible to regulation, then enter another subsection, for example,

Audio - Normal - Media - there will be an opportunity to adjust the overall volume level.

Sub points:
Sph - volume levels during a telephone conversation,
Mic - microphone sensitivity levels,
Ring - the volume of the call,
Media - volume when playing music, movies, in games.

Call volume levels are set in Audio - LoudSpeaker - Ring
Max Vol = 150
Levels: 120 130 145 160 180 200 (more begins to wheeze)

Telephone speaker volume levels in Audio - Normal - Sph
Max Vol = 150
Levels: 100 120 130 135 140 145 150 150

Audio microphone talk volume levels - Normal - Mic
Levels: 100 172 172 172 172 172 172

Multimedia volume levels are set in Audio - LoudSpeaker - Media
Max Vol = 150 (it is the same for the whole section)
Levels: 110 130 160 190 210 230 250

All the same can be configured for the Headset mode (Headphone), by analogy:

Speakerphone volume levels are set in Audio - LoudSpeaker - Sph
Max Vol = 150 (it is the same for the whole section)
Levels: 80 100 110 120 130 140 150 (more starts to wheeze)

Improving energy saving by setting GSM (3G)

The cellular communication system is designed in such a way that the mobile phone constantly searches for the “best option” - it continuously scans the radio air, finds cellular communication stations (“towers”), communicates with them, analyzes the signal strength of each station, and switches to the station with the best parameters. A regular GSM phone can operate on 4 radio frequencies, collected in two pairs: "900MHz + 1800MHz" and "850MHz + 1900MHz". The first pair is allowed for use in Europe (including Russia), the second pair is used for example in America. With the default settings, the GSM phone constantly scans all 4 radio frequencies in search of a signal from cellular stations. But for example in Russia at frequencies "850MHz + 1900MHz" there is no cellular radio signal (they are used / reserved for other purposes), and precious electric energy is literally wasted in analyzing these frequencies.
In many phones (including Android), there are ways to call the so-called "Engineering menu" - a program that allows you to change the hardware settings of the phone. In this menu, you can disable the work of the radio module of the phone with frequencies that are not used in the country of location. For Russia, this is a pair of frequencies "850MHz + 1900MHz".
Open the "Engineering menu"*#*#3646633#*#* A menu will appear on a black background, find and select the item "BandMode", there will be a menu with one item "SIM1" (for single-SIM-cell phones), or with two items "SIM1" and "SIM2" (for two-SIM full-time phones). You need to enter each item, and remove the check marks from the items "GSM850" and "PCS1900", then press the "SET" button.
For phones with UMTS (3G) support, it is also recommended to turn off the “WCDMA-800”, “WCDMA-CLR-850”, “WCDMA-PCS-1900” points that are not used in Russia, also remembering to press the “SET” button.
And if you do not use the UMTS mode (there is a GSM SIM card in this slot), you can turn off all the "WCDMA- *" items, leaving "WCDMA-IMT-2000" as the most economical in terms of power consumption (completely disable all the checkboxes at least for me - just like that). So go to the item "RAT Mode" ->"SIM1", and switch the radio "Set preferred network type:" to the "GSM Only" mode

Also very useful in add. wifi settings tick "Wifi in talk mode - only when powered from the network "(call the additional menu with the button or" three points "in the corner)
To enter the engineering menu MTK dial on the phone*#*#3646633#*#* (iron tests, GSM setup, sound setup)
Attention! You can spoil the device! record your values ​​before making changes.

Checked the work of the GPS. On a city street with WIFI and 3G disabled, a “warm start” took half a minute. Then he got on the subway, moved several kilometers, went out - a “hot start” for 10 seconds. At the same time, there was no difficulty in reading the Navitelov card in the midday sun (on the question of the screen in the sun).

[Vadim_ja]

So. About mobile communications. Detailed report.
Yesterday, when buying SIM cards, it was not possible to launch 3G in the operator’s office. And 2G worked, but 3G refused. After much suffering (3G connected after 7-8 minutes of waiting, the phone was losing the network, I did not achieve data transfer) spat and did a factory reset. I want to note that turning on the volume with the volume rocker clamped down sends the body to the Chinese recovery with hieroglyphs and tea ceremony, but from MobileUncl the download of the recovery results in a normal English language recovery. Now it connects to 3G in seconds, the network is stable, SpeedTest has issued almost 2M reception and 322K transmission.
Operator 3mob (Ukraine), package "Start".

Hooray!

Charge report
The tablet was charged in the off state. Charging was done through the UT33C device included in the ammeter mode in the gap of one of the two left wires of the broken cable. The tablet was discharged to 1%. The voltage on the battery according to the testimony of the internal sensor 3,25V. Charging lasted 9 hours and did not end, unfortunately had to interrupt the process by 88%. The charger voltage remained stable for the entire charge of 5V. The current changed slightly. In this case, the charger may well produce more current, tested on the example of a smartphone charge. That is, the current is limited by the tablet charge controller.

After 9 hours, 20.8125 W * h were transmitted to the device in the direction of the capacity declared by the manufacturer of 16.65 Wh. That corresponds to a very plausible charging efficiency of 70%. Nargev tablet was not marked. Charging was heated moderately.

Summary. The claimed capacity of 4500 mAh seems to be quite plausible. It should be remembered that a full charge of the tablet from ANY charger will take at least 10 hours.

Happy owners, please share information about the self-discharge of the battery:
How long can the device keep off, how long does the battery last in the standby mode in airplane mode (with the network disconnected), and how much can it reach in the phone mode (with the GSM module in standby mode)? Thanks a lot in advance.

[Vadim_ja]

Pafnutij007 @ 08/04/2013 02:00

in standby mode in airplane mode (with network disconnected)

While I can reliably say only about it :) In 10 hours in airplane mode, the tablet ate about 2% of the battery.

Pafnutij007 @ 08/04/2013 02:00

phone mode (with the GSM module in standby mode)

It strongly depends on the conditions of reception and use of 2G / 3G. Experimenting - accomplish your goal.

[Vadim_ja]

Much depends not only on the brightness of the screen. Good eats WiFi battery, it consumes 2G / 3G in conditions of poor reception. But in general, 6-7 hours of active use seem to be a very plausible figure.

I take this opportunity to inform you that Ntfs Mounter did not start with me, and Paragon NTFS & HFS + safely mounts flash drives marked in NTFS.

On the issue of performance and battery life. Below are the parameters of the film, which comes in delivery with the MXPlayer tablet when hardware decoding is played with occasional slowdowns. At the same time, the installation of software decoding allows you to watch a movie without visible brakes, but after 30 minutes of watching a movie, the battery charge is reduced by 18%.

Is ipad mini case suitable for this device?

Depending on what to call a cover)
any sleeve from iPad mini will certainly fit
and smart covers won't fit (dimensions are different)

[Vadim_ja]

Mikhaillll @ 08/06/2013, 10:25

(dimensions differ)

Cube U55GT: 200.2 * 134.8 * 7.4mm
iPad mini: 200 * 134.7 * 7.2 mm

Taking this opportunity I want to ask. The set of quick launch icons (in the right curtain) is not edited by system tools. How to be? Gravibox set somehow dumb ...

[Narkusoid]

Yes, I was joking, in Photoshop I put the images of one device on another, I got differences only in the location of the speakers (they are more spread apart in the cube, about half of each is closed on both sides), and the rest of controls coincided.
as an option it should be finehttp://www.aliexpress.com/item/2013-New-Ar.../722192380.html

Energy consumption measurements continue. I hasten to please the questioner - 3G is turned on (with the data transmission turned off) the battery is practically not eating. 1% in 4.5 hours, which is comparable to the discharge in the "flight" mode.

[umbr42]

I thinksuchcovers should be viewed from the sides only and the speakers will not close.

Thank you very much, the results on the battery are encouraging.

Also very good news. And with his (Paragon NTFS & HFS) using HDD drives you can mount?
Here I sit and think, order now or wait for the release of the 32Gb version, or this will not happen at all?

Can. The program from the market. Free However, it may be necessary to supply external power, I have not yet experimented.

Pafnutij007 @ 08/06/2013, 20:19

On the night of charging. Not every night. I have more than an hour a day to watch a movie on the tablet, there is no need or possibility :)

Pafnutij007 @ 08/06/2013, 20:19

Did this mean that in phone mode (GSM only)?

In WCDMA phone mode. In principle, GSM should consume even less. But this is subject to the stillness of the device. On the road, he will move from cell to cell and waste energy.
