[Huawei MediaPad X2] Benjiro:
If you only look at the basic specs, the LeTV Max "looks" better. More memory, higher resolution screen, slightly faster CPU, faster GPU, compacter...

But there is also where it ends. The 810 is a know throttle monster that easily hits its thermal limits ( what most manufactures solve by limiting the SOC ). Its also not exactly friendly on the battery. My X2 even after hours of playing Fallout Shelter ( what is a know battery eater ), was just "warm". Not hot, just warm. I doubt that the same can be said about the 810 in the LeTV.

1440x2560? I do not care... On the X2 7" 1080p, you need to have 21/20 eyesight to see the pixels or have the phone right in front of your eyes. What people forget it, that the higher resolution = less space for light to pass = more / higher back light is needed = more power usage. And my eyesight is 20/20.

4GB Ram ... everybody love more ram. But lets be realistic... on my Sony ZU, i always had a health 500+ MB ( 0.5GB ) free in regards to ram ( comparing Android 5 on both systems ). And that was with a device that had two years worth of programs active. On my X2, i have between 1.7GB and 1.8GB free. So assuming the same program load like the ZU, there will be close to 1.5GB ( X2 had 1GB more ram then the ZU ) still free. That means on the LeTV, your looking at 2.5GB memory free with the same load. Nice ...

Camera ... If you come from a ZU, anything is a massive upgrade *lol*...

And now we come to the real reason to own the X2: 5000 mAh x 3400 mAh ...

Its not just 50% more battery power. The ZU also had a 3050mAh battery. Yet, my own battery results are more then impressive. So far the X2 is hitting 2 a 3 times the battery life consistently against then ( 2 year old ) ZU.

Technology has improved... While the X2 has a bigger screen, it seems to be more power efficient. The SOC is designed around those power efficient cores from bottom to top. Its a monster, not just pure on battery but in regards to battery life.

My best proof are some of the basic usage test i did before.

And i forgot that i still had the GPS on for the X2. *oeps*. And the GPS like most receivers/transmitters are more battery eaters.

Real life battery:

On 25/08 at 21.30 i charged up the battery to 100%.

We are 28/08 around 22.30 and my battery is ... 68%.

In that time i spend around 20 minutes calling ( 2 * 10 min ), checking wechat, some quick surfing on 4G, doing some basic battery testing ( one day with 4G+Wifi, one day with 2G+Wifi, one day with 2G. And Wifi on at night ) and a bunch of other thing. For this same amount of time, my ZU will hit 15% on the battery left, with only 4G on during the day and Wifi at night.

Its a battery life monster! And thanks to some testing, i found that the best combination is:

Set 2G when your at work and only need to check wechat or other chat messages. 4G drains twice as much. Enable 4G only when you need to surf. For basic text chatting 2G is the same effect as 4G, you do not notice the difference ...

Wifi/basic phone active drains about 3 a 4% in about 12 hours at night/morning.

2G/basic phone active / some times chatting during the day ( at work ), drains about 3 a 4% ( depends on the intensity that you chat/check/etc ) in +- 9 hours.

So with this combination, found that i can survive 24 hours, using maybe 6 a 8%, 10% in extreme for basic thing that i did before with my ZU, that took out maybe 30 a 40% ( yes, its not accurate because the ZU was using 4G all the time during the day ).

But to get back to the basic comparison:

The LeTV has a maybe more powerful CPU, GPU, more memory and higher resolution smaller screen combined with a smaller batter. Do the math? You know that your battery life at best will be "average". If you can live with that, then the LeTV is for you. But if you are like me, fed up with average battery life, then the X2 is way more up your alley.

Frankly, i do not know of any device that offers this size, battery life and still has phone capability... Beyond the X1 but that is running older A9 Cpu cores. The X2 beats the ZU with 25% in Antutu and frankly, i notice no slowdowns or other problems. And regarding faster GPU's. Sorry, but what do you care about the GPU? Those 3d games kill any device its battery, for what? If you want to really game, there are PC's, Console etc, where you can more enjoy the 3D experience. I found devices like this better with games that are more designed for the platform ( hard to explain ).

O and here is other a counter argument:

PRICE! X2 for 3GB/32GB = 399 Euro. The LeTV Max cheapest i found is 620 euro's... And i was lucky and was able to buy my X2 in a auction at 341 euro :D

I long time learned that specs alone do not make a good device, its the combination of those specs. I am frankly fed up with phone's that has a zillion "look how fast or how big resolution or " ... but they forget to mention that those things in general eat battery life and force people to spend every two or one! day recharging there phone. And the more you recharge, the more your battery capacity goes down. Fun these days with non-replaceable batteries.

Speaking of non-replaceable batteries. How is the LeTV its battery replacement? Also non-removable like most devices these days. I ask because the ZU its a disaster... you need to heatgun the glass to remove the glue, and then deal with a annoying flat cable. The X2 its just popping off some plastic, a few screws and you can simply unplug the power connector. The X2 battery replacement anybody can do.
