[Lenovo K900] rdosti:
Sorry was out of town celebrating Diwali (our Hindu festival of lights). I took my device with me and watched movies during my flights, took photos and 4K videos while I was in Coorg (a wonderful hill station)!

I have had absolutely no problems with the software. In fact they released a firmware update for Stability issues and the UI is quite fast. I have not had a single reset, hang, restart, screen lock issues or whatever else you have noted as rumoured problems. In my opinion these are words from lousy people who want to bad mouth one of the best devices ever launched this year. They have not advertised much but from what I have been told, read and heard :) .. .the engineering team at Lenovo were given an open budget to work on a device they felt was "everything" to make it the smartest device ever and they did just that. This is probably the first UI I have found to be simple yet informative for a person like me, and yet offers advance functionality to make the device one of the greatest devices ever made/build.

Let me put it this way - If you don't buy this device (if it's on your consideration list) , you're making a big mistake. I think this is truly at it's price tag (low!) a fantastic buy. However, having said that - the next best thing (or perhaps better) would be the new Nexus 6, which probably beats this device (2nd best).

MY battery lasts almost two days with moderate calling, 2 hour video a day (720P), internet access, games , etc.

I only use bright mode for the movies though otherwise I use Auto Brightness modes throughout the day. I use the Vibe UI with the latest firmware update released two weeks ago.

I slept last night at 68% and when I woke up had 67% (slept for 8 hours!).

So no, I am not experiencing your battery drain issues. I would suggest checking the extensive list of settings. Download and Install "Clean Master". I have found my device both fast and stable before and after using the app.

Yes 4K screens do use up battery life fairly quickly on the Snapdragon 801 set. This is better on the 805 set though currently used by only two devices - Note 4 & Nexus 6.

LG 3 users face a similar problem as us, thats why they put a larger battery considering the problem as well as the larger screen. Larger the screen, the larger the battery you need for 4K screens (at least until a better chipset comes out).

Hope that helps.

Rooting generally removes the option to get OTA updates for almost all phones/devices..

However, I might be wrong. Best to ask Lenovo.

No for both.

GSM Arena has tons of people who don't have the device and comment stupidly.

You are worrying too much. I would suggest not buying the device if you have so many worries. If you are within the one year (obviously) warranty period just get your piece repaired or replaced. MY device is flawless (so far) and I use it as my primary device. I am quite surprised with what user complaints are - but then again it may be a total box of faulty devices. Get them replaced immediately. I have a solid set of buttons on my device (volume and power). I have found no over heating at all which is quite surprising - that being said I watch 720 P movies and not 4K videos (Can you really get good 4K movies ??!! Where!!?) I do understand everyone has his/her doubts before buying a product, but I think if you're over conscious this may not be the phone for you (if your expectations are the moon). That being said, you would probably be better off buying the Note 4.

If you want to see a Heating issue phone - its the Z3 - It can not record more than 15 seconds of 4K video before a stupid error popups warning you that your phone is over heating, etc. Now that's just stupid. There are large XDA users complaining of broken screens, etc. So if you were to worry about any phone the Z3 would scare the living **** out of you (and me!).

:)

Relax.
